Description

L'invention concerne une unité mobile de nettoyage d'un réseau d'égout depuis un regard.The invention relates to a mobile unit for cleaning a sewer system from a viewpoint.

On entend par unité mobile à la fois un ensemble autotracté tel qu'un véhicule sur roue, de type camion, ou bien un ensemble qui sera lui-même tracté, tel qu'une remorque, un wagon ou encore un ensemble susceptible d'être monté sur une remorque ou le châssis d'un véhicule.By mobile unit is meant both a self-propelled assembly such as a wheeled vehicle, of the truck type, or an assembly which will itself be towed, such as a trailer, a wagon or an assembly likely to be mounted on a trailer or chassis of a vehicle.

Il existe des camions, appelés combinés hydrocureurs, permettant de réaliser à la fois l'hydrocurage et l'aspiration des réseaux d'assainissement, c'est-à-dire permettant d'enlever les dépôts accumulés dans les regards et les canalisations adjacentes au moyen d'un tuyau de nettoyage comportant une tête de curage envoyant de l'eau à haute pression et d'un tuyau pour l'aspiration des boues et résidus liquides.There are trucks, called combined water purifiers, to perform both the hydrocure and the aspiration of sewerage networks, that is to say to remove deposits accumulated in manholes and pipes adjacent to means of a cleaning pipe comprising a cleaning head sending water at high pressure and a pipe for the suction of sludge and liquid residues.

On comprend que ce type d'équipement doit permettre à l'opérateur, qui reste près du regard d'égout situé sur la chaussée, de placer le tuyau de nettoyage comportant la tête de curage à son extrémité dans le regard d'égout, à (aux) l'emplacement(s) souhaité(s), de le tenir en position tout le long de l'opération de nettoyage sous haute pression, tout en commandant l'envoi de l'eau sous haute pression, puis de le remonter sur le camion. Ensuite, l'opérateur doit réaliser les mêmes opérations de positionnement, de commande, de maintien et de remontée avec le tuyau pour l'aspiration.It is understood that this type of equipment must allow the operator, who remains near the manhole located on the road, to place the cleaning pipe with the cleaning head at its end in the manhole, to the desired location (s), hold it in position all the way through the high-pressure cleaning operation, while ordering the high-pressure water to be sent and then reassembled on the truck. Then, the operator must perform the same operations of positioning, control, maintenance and recovery with the pipe for suction.

De ce qui précède, on comprend qu'il y a donc beaucoup de manipulations que l'opérateur doit réaliser, sans pouvoir avoir une bonne vision de la position dans l'intérieur du regard, et donc sans garantir un bon nettoyage si des zones n'ont pas été lavées et/ou aspirées.From the foregoing, it is understood that there are so many manipulations that the operator must realize, without being able to have a good vision of the position in the interior of the gaze, and thus without guaranteeing a good cleaning if areas n have not been washed and / or aspirated.

En outre, notamment lors de la remontée des tuyaux, et en particulier du tuyau de nettoyage, il peut se produire des éclaboussures parvenant en dehors de la bouche d'égout ce qui, combiné à la souillure éventuelles des tuyaux, va conduire à une situation et des manipulations parfois très inconfortables pour l'opérateur.In addition, especially during the ascent of the pipes, and in particular the cleaning pipe, it may occur splashing out of the mouth of the sewer which, combined with the possible contamination of the pipes, will lead to a situation. and manipulations sometimes very uncomfortable for the operator.

On connaît, du document DE 102 46 041 un véhicule de nettoyage qui comporte un bras monté sur le véhicule en étant mobile par rapport au véhicule en pivotement autour d'un axe vertical et en translation horizontale, le bras portant un tuyau d'aspiration et un tuyau de nettoyage.We know from the document DE 102 46 041 a cleaning vehicle which comprises an arm mounted on the vehicle being movable relative to the vehicle pivotally about a vertical axis and in horizontal translation, the arm carrying a suction pipe and a cleaning pipe.

Egalement, le document EP0698696 présente un véhicule de nettoyage équipé d'un tuyau de nettoyage à haute pression et d'un tuyau d'aspiration montés sur une flèche télescopique pivotante horizontale.Also, the document EP0698696 has a cleaning vehicle equipped with a high-pressure cleaning hose and a suction hose mounted on a horizontal swiveling telescopic boom.

Le document DE 43 35 188 porte sur un véhicule comprenant une unité mobile conforme au préambule de la revendication 1.The document DE 43 35 188 door on a vehicle comprising a mobile unit according to the preamble of claim 1.

Les documents DE 29 48 780 A1 , DE 299 09 623 U1 , AT 377 297 B et DE 296 24 308 U1 concernent également des véhicules de nettoyage.The documents DE 29 48 780 A1 , DE 299 09 623 U1 , AT 377 297 B and DE 296 24 308 U1 also concern cleaning vehicles.

Cependant, on cherche à permettre une plus grande précision de la position des tuyaux d'aspiration et de nettoyage, notamment au dessus du regard d'égout, et en particulier à proximité du regard, et dans le regard, à la fois en direction verticale (hauteur/ profondeur) et en direction radiale autour d'un axe vertical passant par le regard d'égout.However, it is sought to allow a greater accuracy of the position of the suction and cleaning pipes, especially above the manhole, and in particular near the gaze, and in the eye, both in the vertical direction (height / depth) and radially about a vertical axis passing through the manhole.

La présente invention a pour objectif de fournir un une unité mobile de nettoyage d'un réseau d'égout permettant de surmonter les inconvénients de l'art antérieur et en particulier offrant la possibilité de faciliter le positionnement précis de l'extrémité de travail des tuyaux d'aspiration et de nettoyage à chaque étape, à savoir dans la phase d'installation des tuyaux, pendant le travail de nettoyage, puis lors de la sortie des tuyaux hors du regard d'égout.The present invention aims to provide a mobile sewer cleaning unit to overcome the disadvantages of the prior art and in particular offering the possibility of facilitating the precise positioning of the working end of the pipes suction and cleaning at each step, ie during the installation phase of the pipes, during the cleaning work, then when the pipes come out of the manhole.

A cet effet, selon la présente invention, l'unité mobile comprend :

  • un tuyau d'aspiration monté sur un dévidoir et relié à un réservoir de collecte et à une pompe d'aspiration,
  • un tuyau de nettoyage à haute pression monté sur un dévidoir et relié à une citerne d'eau, à une pompe haute pression et à une tête de curage,
  • un bras de support et de guidage du tuyau d'aspiration et du tuyau de nettoyage, ledit bras comportant une partie horizontale reliée à l'unité mobile en étant mobile en rotation autour d'un axe vertical et en translation horizontale par rapport à l'unité mobile afin de permettre le positionnement de l'extrémité de travail des tuyaux d'aspiration et de nettoyage au dessus du regard d'égout,
ledit bras comportant en outre une partie verticale reliée à la partie horizontale, la liaison entre la partie horizontale et la partie verticale du bras formant un coude articulé par une rotule et ladite partie verticale présentant un module inférieur mobile en rotation et en translation verticale par rapport à ladite partie horizontale,
les tuyaux d'aspiration et de nettoyage étant reliés audit module inférieur, ce par quoi le positionnement du module inférieur correspond sensiblement à celui de l'extrémité de travail des tuyaux d'aspiration et de nettoyage.For this purpose, according to the present invention, the mobile unit comprises:
  • a suction pipe mounted on a reel and connected to a collection tank and a suction pump,
  • a high pressure cleaning hose mounted on a reel and connected to a water tank, a high pressure pump and a cleaning head,
  • an arm for supporting and guiding the suction pipe and the cleaning pipe, said arm comprising a horizontal part connected to the mobile unit being rotatable about a vertical axis and in horizontal translation with respect to the mobile unit to allow positioning of the working end of the suction and cleaning pipes above the manhole,
said arm further comprising a vertical portion connected to the horizontal portion, the connection between the horizontal portion and the vertical portion of the arm forming a hinge articulated by a ball joint and said vertical portion having a lower module movable in rotation and in vertical translation relative at said horizontal portion,
the suction and cleaning pipes being connected to said lower module, whereby the positioning of the lower module corresponds substantially to that of the working end of the suction and cleaning pipes.

De cette manière, on comprend que par les différents degrés de liberté du bras de support et de guidage, on obtient une précision importante de la position du tuyau d'aspiration et du tuyau de nettoyage portés par ce bras de support et de guidage.In this way, it is understood that by the different degrees of freedom of the support arm and guide, one obtains a precision important position of the suction pipe and the cleaning pipe carried by this support arm and guide.

En effet, par les équipements prévus au niveau de la partie horizontale du bras, celui-ci est mobile dans son ensemble en rotation autour d'un axe vertical et toute sa partie verticale est mobile en translation horizontale par rapport à l'unité mobile.Indeed, by the equipment provided at the horizontal portion of the arm, it is movable as a whole in rotation about a vertical axis and the entire vertical portion is movable in horizontal translation relative to the movable unit.

De plus, de façon spécifique à l'invention, la partie verticale du bras comporte des aménagements permettant à son extrémité inférieure, le module inférieur, d'être mobile à la fois en rotation autour d'un axe vertical et en translation verticale.In addition, in a specific manner to the invention, the vertical portion of the arm comprises arrangements for its lower end, the lower module to be movable both in rotation about a vertical axis and in vertical translation.

De cette façon, on comprend que l'on obtient aisément le positionnement souhaité du module inférieur, et donc de l'extrémité de travail des tuyaux d'aspiration et de nettoyage à l'intérieur du regard d'égout.In this way, it is understood that the desired positioning of the lower module, and therefore of the working end of the suction and cleaning pipes inside the manhole, is easily achieved.

Cette solution présente aussi l'avantage supplémentaire, d'éviter un mouvement intempestif des tuyaux d'aspiration et de nettoyage, et notamment que l'extrémité du tuyau de nettoyage, équipée d'une tête de curage, ne remonte et percute l'opérateur, ou encore que ce tuyau de nettoyage ne s'use en frottant la paroi de la bouche d'égout ou des canalisations.This solution also has the additional advantage of avoiding inadvertent movement of the suction and cleaning pipes, and in particular that the end of the cleaning pipe, equipped with a cleaning head, does not rise and collide with the operator. or that this cleaning pipe is worn out by rubbing the wall of the manhole or pipes.

Globalement, grâce à la solution selon la présente invention, il est possible de faciliter grandement le travail de l'opérateur qui devient plus précis et moins pénible, ce qui procure une plus grande efficacité des opérations de nettoyage.Overall, thanks to the solution according to the present invention, it is possible to greatly facilitate the work of the operator which becomes more precise and less arduous, which provides a greater efficiency of the cleaning operations.

De préférence, la liaison entre la partie horizontale et la partie verticale du bras forme un coude articulé par une rotule n'autorisant qu'un débattement maximal de 15°, et préférentiellement de 5°, tout au plus de 3°, entre la partie horizontale et la partie verticale.Preferably, the connection between the horizontal portion and the vertical portion of the arm forms a hinge articulated by a ball joint allowing a maximum deflection of 15 °, and preferably 5 °, at most 3 °, between the part horizontal and the vertical part.

Avantageusement, la partie horizontale du bras comporte des premiers moyens d'entraînement et une première articulation à pivot permettant ledit mouvement de rotation autour d'un axe vertical par rapport à l'unité mobile , la partie horizontale du bras comportant en outre des deuxièmes moyens d'entraînement et plusieurs profilés emboîtés les uns dans les autres qui sont aptes à réaliser ledit mouvement de translation horizontale de la partie horizontale du bras par déplacement télescopique entre les profilés grâce auxdits deuxièmes moyens d'entraînement. Par exemple, ces deuxièmes moyens d'entraînement comprennent un vérin hydraulique situé en position centrale de l'ensemble de profilés emboîtés.Advantageously, the horizontal portion of the arm comprises first drive means and a first pivot joint allowing said rotational movement about a vertical axis relative to the mobile unit, the horizontal portion of the arm further comprising second means and a plurality of interlocking profiles which are adapted to perform said horizontal translation movement of the horizontal part of the arm by telescopic displacement between the profiles by said second means drive. For example, these second drive means comprise a hydraulic cylinder located centrally of the set of nested sections.

Selon une disposition préférentielle, la partie verticale du bras comporte en outre un module supérieur qui est relié à la partie horizontale et qui présente des troisièmes moyens d'entraînement aptes à permettre le mouvement de translation verticale du module inférieur. Ces troisièmes moyens d'entraînement comprennent par exemple un treuil électrique associé à un câble avec possibilité de débrayage pour passer en commande manuelle. D'autres formes de mise en oeuvre peuvent être prévues pour ces troisièmes moyens d'entraînement, telles que l'utilisation d'un vérin de commande.According to a preferred arrangement, the vertical part of the arm further comprises an upper module which is connected to the horizontal part and which has third drive means able to allow the vertical translation movement of the lower module. These third drive means comprise for example an electric winch associated with a cable with the possibility of disengagement to switch to manual control. Other forms of implementation may be provided for these third drive means, such as the use of a control jack.

Dans ce cas, avantageusement, la partie verticale du bras comporte en outre une deuxième articulation à pivot comprenant une couronne et des quatrièmes moyens d'entraînement permettant le mouvement de rotation autour d'un axe vertical du module inférieur. Ces quatrièmes moyens d'entraînement comprennent par exemple un moteur de commande de la deuxième articulation à pivot pour permettre la rotation du bras vertical, la couronne pouvant revêtir différentes formes parmi lesquelles celle d'une bague à roulements, à segments...In this case, advantageously, the vertical portion of the arm further comprises a second pivot joint comprising a ring and fourth drive means for the rotational movement about a vertical axis of the lower module. These fourth drive means comprise for example a control motor of the second pivot joint to allow rotation of the vertical arm, the crown can take various forms, including that of a bearing ring, with segments ...

De plus, dans ce même cas, on prévoit de préférence que la partie verticale du bras comporte en outre un module intermédiaire, situé entre le module inférieur et le module supérieur, en étant relié à la couronne de l'articulation à pivot, et qui comporte plusieurs profilés emboîtés les uns dans les autres et aptes à réaliser ledit mouvement de translation verticale de la partie verticale du bras par déplacement télescopique entre les profilés grâce auxdits deuxièmes moyens d'entraînement de la partie supérieure, ce par quoi le module inférieur est entraîné selon le même mouvement de translation verticale, un des profilés du module intermédiaire étant fixé sur la couronne de l'articulation à pivot.In addition, in this case, it is preferably provided that the vertical portion of the arm further comprises an intermediate module, located between the lower module and the upper module, being connected to the crown of the pivot joint, and which comprises a plurality of profiles fitted into each other and capable of performing said vertical translation movement of the vertical part of the arm by telescopic displacement between the sections by virtue of said second drive means of the upper part, whereby the lower module is driven according to the same vertical translation movement, one of the profiles of the intermediate module being fixed on the ring of the pivot joint.

Selon une autre disposition préférentielle, le tuyau d'aspiration est relié de façon détachable à ladite partie verticale du bras. Par exemple, l'extrémité libre du tuyau d'aspiration est logée de façon télescopique dans un fourreau relié à la partie verticale du bras.According to another preferred arrangement, the suction pipe is detachably connected to said vertical part of the arm. For example, the free end of the suction pipe is telescopically housed in a sleeve connected to the vertical part of the arm.

Ainsi, de préférence, le module inférieur est muni d'une bague permettant de retenir le tuyau d'aspiration, via le fourreau, de sorte qu'il suive les déplacements du module inférieur.Thus, preferably, the lower module is provided with a ring for retaining the suction pipe, via the sleeve, so that it follows the movements of the lower module.

De façon générale, on prévoit avantageusement que le module inférieur permet de décaler le tuyau d'aspiration autour du tuyau de nettoyage formant la position centrale, par un indexage radial. Une telle disposition permet par exemple de venir nettoyer des zones adjacentes de la cunette qui fait face au regard d'égout, telles que les banquettes latérales.In general, it is advantageously provided for the lower module to shift the suction pipe around the cleaning pipe forming the central position, by radial indexing. Such an arrangement makes it possible, for example, to clean adjacent areas of the cunette which faces the manholes, such as the side benches.

Selon un mode de réalisation, le tuyau d'aspiration est mobile en rotation par indexage via une bague par rapport à une prolongation des profilés du module intermédiaire.According to one embodiment, the suction pipe is rotatable by indexing via a ring relative to an extension of the profiles of the intermediate module.

Selon une autre caractéristique préférentielle, les parties horizontale et verticale du bras sont munies d'un système de guidage du tuyau d'aspiration et/ ou du tuyau de nettoyage par éléments roulants.According to another preferred feature, the horizontal and vertical parts of the arm are provided with a guide system of the suction pipe and / or the roller cleaning pipe.

Avantageusement, le module inférieur comprend en outre un module caméra permettant, depuis le module inférieur, de visualiser l'intérieur du regard et les zones de canalisation adjacentes. Une telle disposition permet de faciliter le diagnostic avant traitement par hydrocurage et/ou le contrôle de l'état de l'installation après cette opération d'hydrocurage. Dans ce cas, avantageusement, ledit module caméra est relié à un système d'acquisition des données et/ou de visualisation par un câble longeant le bras de support et de guidage. Ainsi, on peut transmettre les informations recueillies via la caméra au système d'acquisition des données et/ou de visualisation qui peut permettre d'effectuer ces contrôles et vérifications à distance ou à moment ultérieur, en particulier par un autre opérateur.Advantageously, the lower module further comprises a camera module allowing, from the lower module, to visualize the inside of the gaze and the adjacent channel zones. Such an arrangement makes it possible to facilitate the diagnosis before treatment by hydrocuring and / or the control of the state of the installation after this hydrocuring operation. In this case, advantageously, said camera module is connected to a data acquisition system and / or visualization by a cable along the support arm and guide. Thus, the information collected via the camera can be transmitted to the data acquisition and / or visualization system which can make it possible to perform these checks and verifications remotely or at a later time, in particular by another operator.

Alternativement ou en supplément du module caméra restant relié au module inférieur, le module inférieur comprend en outre un support apte à recevoir un chariot autonome équipé d'une caméra mobile. Dans ce cas, la caméra mobile peut se déplacer dans le réseau et recueillir des informations visuelles relatives à d'autres zones que celle directement située dans le prolongement vertical ou à proximité du regard d'égout.Alternatively or in addition to the remaining camera module connected to the lower module, the lower module further comprises a support adapted to receive a stand-alone carriage equipped with a mobile camera. In this case, the mobile camera can move in the network and collect visual information relating to other areas than that directly located in the vertical extension or near the manhole.

De préférence, le module inférieur comporte en outre un organe d'appui déployable apte à venir en contact avec la structure du regard d'égout. Un tel organe permet de faciliter la précision du positionnement des tuyaux d'aspiration et de nettoyage et évite tout mouvement intempestif engendré par la pression de l'eau principalement en éjection sous haute pression pour le nettoyage. Cet organe est par exemple constitué d'un manchon déployable dans lequel est guidée l'extrémité de travail du tuyau de nettoyage, portant la tête de curage.Preferably, the lower module further comprises a deployable support member adapted to come into contact with the structure of the manhole. Such an organ makes it possible to facilitate the accuracy of the positioning of the suction and cleaning pipes and prevents any inadvertent movement caused by the pressure of the water mainly by ejection under high pressure for cleaning. This member consists for example of a deployable sleeve in which is guided the working end of the cleaning pipe, carrying the cleaning head.

Avantageusement, l'unité mobile comprend en outre une cloche de protection mobile en translation verticale autour de la partie verticale du bras et apte à venir entourer le bras au dessus du regard d'égout.Advantageously, the mobile unit further comprises a movable protective hood in vertical translation around the vertical portion of the arm and adapted to surround the arm above the manhole.

De cette façon, cette cloche referme le regard pour l'opérateur qui est ainsi protégé de toute éclaboussure et des éventuelles odeurs supplémentaires générées par les opérations de nettoyage par hydrocurage et aspiration, tout en permettant les manoeuvres du bras (en particulier le mouvement de translation verticale de la partie verticale du bras). On comprend que cette cloche, qui fait de préférence partie du module intermédiaire, apporte une protection pour l'opérateur, que ce soit en termes d'hygiène et de diminution des risques sanitaires et/ou plus généralement en termes de sécurité. De plus, on prévoit avantageusement que le mouvement de montée/descente de la cloche est asservi au mouvement du tuyau de nettoyage.In this way, the bell closes the eyes for the operator who is thus protected from any splash and any additional odors generated by the cleaning operations by hydrocuring and suction, while allowing the maneuvers of the arm (in particular the translational movement vertical of the vertical part of the arm). It is understood that this bell, which is preferably part of the intermediate module, provides protection for the operator, whether in terms of hygiene and reduced health risks and / or more generally in terms of safety. In addition, it is advantageously provided that the up / down movement of the bell is slaved to the movement of the cleaning pipe.

Selon une autre possibilité préférentielle, la cloche de protection comporte un module caméra, mobile au moins de façon verticale par rapport au bras de support et de guidage et permettant de visualiser l'intérieur du regard d'égout et les zones de canalisation adjacentes. Dans ce cas, il faut comprendre que ce module caméra de la cloche joue le rôle de l'éventuel module caméra du module inférieur cité précédemment. De cette façon, on dispose grâce à ce module caméra logé, au repos, dans la cloche, d'un moyen d'exploration et de visualisation du regard d'égout et de son environnement. De préférence, ce module caméra est autonome dans sa commande et ses mouvements du bras de support et de guidage, par exemple grâce à un système lui permettant de se déplacer selon un mouvement télescopique vertical réversible.According to another preferred possibility, the protection bell comprises a camera module, movable at least vertically with respect to the support arm and guide and for viewing the interior of the sewer manhole and adjacent pipe zones. In this case, it should be understood that this camera module of the bell plays the role of the possible camera module of the lower module mentioned above. In this way, it is possible thanks to this camera module housed, at rest, in the bell, a means for exploring and viewing the manhole and its environment. Preferably, this camera module is autonomous in its control and movements of the support arm and guide, for example through a system allowing it to move in a reversible vertical telescopic movement.

La présente invention porte également sur un véhicule comprenant une unité mobile de nettoyage telle que présentée précédemment.The present invention also relates to a vehicle comprising a mobile cleaning unit as presented above.

Sur la figure 1, un véhicule 100 comporte sur son châssis arrière 102 un ensemble d'équipements parmi lesquels une (ou plusieurs) cuve(s) 110 ainsi qu'une unité mobile 200.On the figure 1 , a vehicle 100 comprises on its rear frame 102 a set of equipment among which one (or more) tank (s) 110 and a mobile unit 200.

Cette unité mobile 200 comporte un bras de support et de guidage 202 constitué d'une partie horizontale 210 qui s'étend horizontalement au niveau de la partie supérieure de la partie arrière du véhicule 100 et d'une partie verticale 220 qui s'étend verticalement en formant l'extrémité arrière du véhicule 100.This mobile unit 200 comprises a support and guide arm 202 consisting of a horizontal part 210 which extends horizontally at the level of the upper part of the rear part of the vehicle 100 and of a vertical part 220 which extends vertically. forming the rear end of the vehicle 100.

Sur cette figure 1, l'unité mobile 200 est représentée dans sa position de repos permettant le déplacement du véhicule 100 car toutes les parties mobiles, qui seront décrites ci-après, sont rétractées.On this figure 1 , the mobile unit 200 is shown in its rest position for moving the vehicle 100 because all the moving parts, which will be described below, are retracted.

Cette unité mobile 200 est plus clairement visible sur la figure 2 sur laquelle il est possible de mieux distinguer toutes les parties constitutives de la partie horizontale 210 et de la partie verticale 220 du bras de support et de guidage 202.This mobile unit 200 is more clearly visible on the figure 2 on which it is possible to better distinguish all the constituent parts of the horizontal portion 210 and the vertical portion 220 of the support and guide arm 202.

Pour effectuer l'hydrocurage, l'unité mobile 200 est équipée en premier lieu d'un tuyau de nettoyage 230 comportant à son extrémité terminale de travail 232 une tête de curage 234, et, en second lieu, d'un tuyau d'aspiration 240 formé, à son extrémité terminale de travail, d'un cylindre 242 (voir figures 2 et 6).To effect the hydrocuring, the mobile unit 200 is equipped firstly with a cleaning pipe 230 having at its working end end 232 a cleaning head 234, and, secondly, a suction pipe 240 formed at its end of work, a cylinder 242 (see figures 2 and 6 ).

Le tuyau de nettoyage 230 et le tuyau d'aspiration 240 sont supportées par le bras 202 , le long de la partie horizontale 210 et le long de la partie verticale 220 par un système de guidage 204 comportant des éléments roulants 206 constitués préférentiellement par des galets de type diabolo (voir les figures 4 et 5). Certains de ces éléments roulants 206 sont des éléments moteurs permettant de déplacer dans les deux sens les tuyaux 230 et 240. En particulier, on peut prévoir que ces éléments moteurs sont des galets presseurs à serrage variable pour la bonne tenue du tuyau 230 et /ou 240 qui est entraîné.The cleaning pipe 230 and the suction pipe 240 are supported by the arm 202, along the horizontal part 210 and along the vertical part 220 by a guide system 204 comprising rolling elements 206 preferably constituted by rollers Diabolo type (see figures 4 and 5 ). Some of these rolling elements 206 are driving elements for moving in both directions the pipes 230 and 240. In particular, it can be provided that these motor elements are variable clamping pressure rollers for the good behavior of the pipe 230 and / or 240 who is trained.

La partie horizontale 210 comporte une embase 211 fixée d'une façon générale sur le véhicule 100, notamment sur le châssis 102 du véhicule 100 ou, comme on peut le voir sur la figure 2, dans le cas du mode de réalisation représenté, l'embase 211 est fixée sur la virole de la cuve 110.The horizontal portion 210 comprises a base 211 fixed generally on the vehicle 100, in particular on the frame 102 of the vehicle 100 or, as can be seen on the figure 2 , in the case of the embodiment shown, the base 211 is fixed on the shell of the tank 110.

Cette embase 211 comporte un moteur 212 repéré par son emplacement sur la figure 2, en particulier hydraulique, formant des premiers moyens d'entraînement qui sont reliés à une première articulation à pivot 213 (voir figures 2 à 4) permettant la rotation du bras 202 par rapport à l'embase 211 et au véhicule 100 autour d'un axe vertical Z1-Z1'.This base 211 comprises a motor 212 identified by its location on the figure 2 , in particular hydraulic, forming first drive means which are connected to a first pivot joint 213 (see Figures 2 to 4 ) allowing rotation of the arm 202 relative to the base 211 and the vehicle 100 about a vertical axis Z1-Z1 '.

La partie horizontale 210 comporte également une tourelle 214 montée au dessus de l'articulation à pivot 213 (voir figures 2 à 4) et qui comporte des éléments roulants 206 du système de guidage 204 (voir figure 4) pour le passage des tuyaux de nettoyage 230 et d'aspiration 240. Cette tourelle 214 est donc mobile en rotation autour de l'axe vertical Z1-Z1'.The horizontal portion 210 also comprises a turret 214 mounted above the pivot joint 213 (see Figures 2 to 4 ) and which comprises rolling elements 206 of the guide system 204 (see figure 4 ) for the passage of the cleaning pipe 230 and aspiration 240. This turret 214 is rotatable about the vertical axis Z1-Z1 '.

Au-dessus de la tourelle 214 est montée une série de plusieurs profilés 215, 216 , 217 et 218 de section rectangulaire de tailles différentes, emboîtés les uns dans les autres de façon à former un ensemble télescopique selon un mouvement de translation en direction horizontale (voir les figures 1 à 4). Cette mise en mouvement est générée par un vérin hydraulique (non représenté) situé à l'intérieur du logement 219 délimité entre les quatre profilés 215, 216 , 217 et 218 et formant des deuxièmes moyens d'entraînement en translation horizontale (voir figure 4).Above the turret 214 is mounted a series of several sections 215, 216, 217 and 218 of rectangular section of different sizes, nested into each other so as to form a telescopic assembly in a translation movement in the horizontal direction ( see the Figures 1 to 4 ). This setting in motion is generated by a hydraulic cylinder (not shown) located inside the housing 219 delimited between the four sections 215, 216, 217 and 218 and forming second drive means in horizontal translation (see figure 4 ).

Les profilés 216 , 217 et 218 sont reliés à des pièces, situées en dessous et qui supportent des éléments roulants 206 pour chacun des tuyaux de nettoyage 230 et d'aspiration 240, ce dernier étant placé au dessous du premier.The profiles 216, 217 and 218 are connected to parts, located below and which support rolling elements 206 for each of the cleaning pipe 230 and suction 240, the latter being placed below the first.

Comme on peut le voir sur la figure 4, la liaison entre la partie horizontale 210 et la partie verticale 220 est réalisée sous la forme d'un coude articulé 250 avec rotule. Plus précisément, cette liaison 250 est une articulation élastique apte à recevoir une forte charge radiale (par exemple de type SPHERIFLEX) et autorisant un débattement angulaire limité entre la partie horizontale 210 et la partie verticale 220, selon les deux axes de ces parties 210 et 220, tout au plus de 15°, et de préférence de 3° ou 5°.As can be seen on the figure 4 , the connection between the horizontal portion 210 and the vertical portion 220 is formed as an articulated elbow 250 with a ball joint. More precisely, this connection 250 is an elastic articulation capable of receiving a high radial load (for example of the SPHERIFLEX type) and allowing limited angular movement between the horizontal portion 210 and the vertical portion 220, along the two axes of these portions 210 and 220, at most 15 °, and preferably 3 ° or 5 °.

Cette liaison 250 est attachée sur le profilé 218 de la partie horizontale 210 et sur le module supérieure 221 de la partie verticale 220. Elle permet de rétablir, notamment manuellement, un positionnement correct de la partie verticale 220 dans certaines situations. Ainsi, lorsque la voie sur laquelle se trouve le véhicule 100 est en pente, le débattement autorisé par la liaison 250 permet de placer la partie verticale 220 d'aplomb, strictement à la verticale. Egalement, si l'entrée du regard se trouve encombré juste en dessous du module inférieur 226, après stationnement du véhicule 100 et déploiement du bras de support et de guidage 202, le débattement autorisé par la liaison 250 permet alors d'incliner légèrement la partie verticale 220 pour permettre l'entrée du module inférieur 226 dans la bouche d'égout 300.This connection 250 is attached to the section 218 of the horizontal portion 210 and the upper module 221 of the vertical portion 220. It allows to restore, including manually, a correct positioning of the vertical portion 220 in certain situations. Thus, when the path on which the vehicle 100 is sloping, the clearance allowed by the link 250 makes it possible to place the vertical portion 220 vertically, strictly vertically. Also, if the entrance of the manhole is confined just below the lower module 226, after parking of the vehicle 100 and deployment of the support and guide arm 202, the clearance allowed by the link 250 then makes it possible to slightly incline the portion vertical 220 to allow entry of the lower module 226 in the manhole 300.

La partie verticale 220 comprend en premier lieu un module supérieur 221 formé essentiellement d'une pièce mécano soudée qui loge la partie correspondante de la liaison 250 dans sa portion supérieure, ainsi que des troisièmes moyens d'entraînement 222 qui vont permettre le mouvement de translation verticale de cette partie verticale 220. À cet effet, les troisièmes moyens d'entraînement 222 comportent (voir figure 4) un treuil électrique 222a associé à un câble 222b et à un moteur 222c de type moto-réducteur. De préférence, on prévoit que le treuil électrique 222a est débrayable de façon à pouvoir effectuer un rembobinage manuel du câble 222b qui est attaché aux parties inférieures de la partie verticale 220, situées sous le module supérieur 221, et ceci pour permettre de remonter les parties inférieures de la partie verticale 220 au cas où un problème électrique interviendrait.The vertical portion 220 comprises firstly an upper module 221 essentially formed of a welded part which houses the corresponding part of the connection 250 in its upper portion, and third drive means 222 which will allow the vertical translation movement of this vertical part 220. For this purpose, the third drive means 222 comprise (see FIG. figure 4 ) an electric winch 222a associated with a cable 222b and a motor 222c motor-geared type. Preferably, it is expected that the electric winch 222a is disengageable so as to perform manual rewinding of the cable 222b which is attached to the lower portions of the vertical portion 220, located under the upper module 221, and this to allow to reassemble the parts lower part of the vertical part 220 in case an electrical problem occurs.

Comme il apparaît également sur cette figure 4, le module supérieur 221 présente une ouverture dans laquelle s'insère le tuyau de nettoyage 230, tandis que le tuyau d'aspiration 240 reste disposé le long mais à l'extérieur du module supérieur 221, sous le tuyau de nettoyage 230, le guidage de ces deux tuyaux 230 et 240 s'effectuant à cet emplacement par d'autres éléments roulants 206, afin de les amener dans une direction verticale.As it also appears on this figure 4 , the upper module 221 has an opening in which the cleaning pipe 230 is inserted, while the suction pipe 240 remains disposed along but outside the upper module 221, under the cleaning pipe 230, the guide these two pipes 230 and 240 being performed at this location by other rolling elements 206, to bring them in a vertical direction.

En partie basse du module supérieur 221 de la partie verticale 220, ont été prévus des quatrième moyens d'entraînement 223 qui vont permettre à la portion de la partie verticale 220 située plus bas d'effectuer une rotation autour d'un axe vertical parallèle à la partie verticale 220. Sur la figure 5, on peut voir un moteur 223a associé à une couronne 223b (par exemple de type ROLLIX) rendue ainsi mobile en rotation par rapport au reste du module supérieur 221 de façon à constituer à cet emplacement une deuxième articulation à pivot 223c.In the lower part of the upper module 221 of the vertical part 220, fourth drive means 223 have been provided which will allow the portion of the vertical part 220 situated below to rotate about a vertical axis parallel to the vertical part 220. On the figure 5 , one can see a motor 223a associated with a ring 223b (for example ROLLIX type) thus rotated relative to the rest of the upper module 221 so as to constitute at this location a second pivot joint 223c.

Sous le module supérieur 221, la partie verticale 220 comporte un module intermédiaire 224 constitué de quatre profilés 224a, 224b, 224c et 224d de section rectangulaire et de tailles différentes, emboîtés les uns dans les autres de façon à former un ensemble télescopique selon un mouvement de translation en direction verticale (voir les figures 5 et 6). Cette mise en mouvement est générée par les troisièmes moyens d'entraînement 222 présentés précédemment, le câble 222b étant relié à l'un ou plusieurs de ces quatre profilés 224a à 224d (liaison non représentée).Under the upper module 221, the vertical portion 220 comprises an intermediate module 224 consisting of four sections 224a, 224b, 224c and 224d of rectangular section and of different sizes, nested one inside the other so as to form a telescopic assembly according to a movement translation in the vertical direction (see figures 5 and 6 ). This setting in motion is generated by the third drive means 222 presented above, the cable 222b being connected to one or more of these four sections 224a to 224d (connection not shown).

De cette façon, lorsque le moteur 222c des troisièmes moyens d'entraînement 222 est activé, en descente ou en montée, le câble 222b entraîne le mouvement vertical de l'ensemble des quatre profilés 224a, 224b, 224c et 224d qui se déploie ou se rétracte selon la direction de la manoeuvre.In this way, when the motor 222c of the third driving means 222 is activated, downhill or uphill, the cable 222b causes the vertical movement of all four sections 224a, 224b, 224c and 224d that unfolds or retracts in the direction of the maneuver.

Comme il apparaît également sur ces figures 5 et 6, à l'emplacement du module intermédiaire 224 le tuyau de nettoyage 230 passe dans le logement intérieur délimité par les quatre profilés 224a, 224b, 224c et 224d, tandis que le tuyau d'aspiration 240 reste disposé le long mais à l'extérieur du module intermédiaire 224, et en particulier à l'extérieur des profilés 224a à 224d, aucun guidage particulier de ces deux tuyaux 230 et 240 s'effectuant à l'emplacement du module intermédiaire 224.As it also appears on these figures 5 and 6 at the location of the intermediate module 224 the cleaning pipe 230 passes into the inner housing delimited by the four sections 224a, 224b, 224c and 224d, while the suction pipe 240 remains disposed along but outside the intermediate module 224, and in particular outside the profiles 224a to 224d, no particular guidance of these two pipes 230 and 240 is performed at the location of the intermediate module 224.

Sous le module intermédiaire 224, la partie verticale 220 comporte un module inférieur 226 qui est destiné à venir se placer au fond de la bouche d'égout 300, sensiblement à l'emplacement de la cunette 304, et qui comporte donc les équipements nécessaires aux opérations que l'unité mobile 200 selon l'invention est apte à réaliser.Under the intermediate module 224, the vertical portion 220 comprises a lower module 226 which is intended to be placed at the bottom of the manhole 300, substantially at the location of the cunette 304, and which therefore comprises the equipment necessary for the operations that the mobile unit 200 according to the invention is able to achieve.

En premier lieu, le module inférieur 226 comporte un manchon souple 226a de section plus faible que celle du profilé intérieur 224d du module intermédiaire 224 et qui est logé dans une prolongation 225 de ce profilé intérieur 224d. Plus précisément, ce manchon 226a s'étend à l'intérieur et en dessous de l'ensemble des quatre profilés 224a, 224b, 224c et 224d du module intermédiaire 224, de sorte que ce manchon 226a sert de guide pour la partie terminale du tuyau de nettoyage 230. Ce manchon 226a est relié de façon solidaire à l'ensemble des quatre profilés 224a à 224d, de sorte qu'il suit leur mouvement. De plus, le manchon 226a retient l'extrémité terminale du tuyau de nettoyage 230 de sorte que la position en direction verticale du tuyau de nettoyage 230 est directement liée à celle du manchon 226a. Le manchon 226a comporte une ouverture 226b (voir figures 6 à 10) dans laquelle débouche la tête de curage 234 de l'extrémité de travail 232 du tuyau de nettoyage 230.First, the lower module 226 comprises a flexible sleeve 226a of smaller section than that of the inner section 224d of the intermediate module 224 and which is housed in an extension 225 of the inner section 224d. More specifically, this sleeve 226a extends inside and below all of the four sections 224a, 224b, 224c and 224d of the intermediate module 224, so that this sleeve 226a serves as a guide for the end portion of the pipe 230. This sleeve 226a is integrally connected to all four sections 224a to 224d, so that it follows their movement. In addition, the sleeve 226a retains the end end of the cleaning pipe 230 so that the vertical position of the cleaning pipe 230 is directly connected to that of the sleeve 226a. The sleeve 226a has an opening 226b (see Figures 6 to 10 ) in which opens the cleaning head 234 of the working end 232 of the cleaning pipe 230.

Egalement, ce manchon 226a est articulé à pivot autour d'un axe horizontal au moyen d'une jambe 228, ce manchon 226a se déplaçant entre une position verticale prolongeant les profilés 224a à 224d, visible sur les figures 6 et 7, et une position déployée visible sur les figures 8, 9 et 10. La jambe 228 comporte une première pièce reliée à pivot sur le bras 202, au niveau d'une extension du profilé extérieur 224d (figure 8) et une deuxième pièce reliée à pivot à l'extrémité libre du manchon 226a, ces première et deuxième pièces de la jambe 228 étant elles-mêmes reliées à pivot autour d'un axe également horizontal.Also, this sleeve 226a is articulated pivotally about a horizontal axis by means of a leg 228, this sleeve 226a moving between a vertical position extending the profiles 224a to 224d, visible on the figures 6 and 7 , and a deployed position visible on the figures 8 , 9 and 10 . The leg 228 includes a first piece pivotally connected to the arm 202, at an extension of the outer profile 224d ( figure 8 ) and a second piece pivotally connected to the free end of the sleeve 226a, these first and second parts of the leg 228 themselves being pivotally connected about an axis also horizontal.

Ainsi, dans sa position déployée visible sur les figures 8 à 10, le manchon 226a sert non seulement de guide pour positionner la tête de curage 234 en direction plus ou moins horizontale, mais également d'organe d'appui. En effet, comme on le voit sur les figures 9 et 10, le manchon 226a peut venir en appui sur la banquette latérale 302 du regard d'égout 300 (cas de la figure 9) ou contre la paroi de la portion de la canalisation ou cunette 304, adjacente au regard d'égout 300 (cas de la figure 10).Thus, in its deployed position visible on the Figures 8 to 10 , the sleeve 226a serves not only as a guide for positioning the cleaning head 234 in a more or less horizontal direction, but also as a support member. Indeed, as we see on the Figures 9 and 10 , the sleeve 226a can bear on the side bench 302 of the manhole 300 (case of the figure 9 ) or against the wall of the portion of the pipe or cunette 304, adjacent to the manhole 300 (case of the figure 10 ).

Ainsi, on comprend que le manchon 226a facilite le travail de nettoyage par hydrocurage en augmentant la stabilité des équipements du module inférieur 226, et en particulier de la tête de curage 234.Thus, it is understood that the sleeve 226a facilitates the cleaning work by hydrocuring by increasing the stability of the equipment of the lower module 226, and in particular of the cleaning head 234.

Alternativement, selon une variante non représentée, cet organe d'appui est réalisé sous la forme d'un étrier basculant grâce à un montage par glissière réalisé sur l'extension du profilé 224d, ainsi qu'à des tringles de retenue montées sur la partie avant de l'étrier, cette dernière venant prendre appui par exemple sur le bord de la cunette 304.Alternatively, according to a variant not shown, this support member is formed in the form of a tilting yoke with a slide assembly made on the extension of the profile 224d, and retaining rods mounted on the part before the stirrup, the latter coming to bear for example on the edge of the cunette 304.

Le cylindre 242 (relativement rigide) formant l'extrémité de travail du tuyau d'aspiration 240 est relié au reste du tuyau d'aspiration 240 (plus souple)par une fixation de type raccord rapide 241. Ce cylindre 242 est disposé le long de ce module inférieur 226, en étant retenu par une bague 227 montée sur une prolongation 225 du profilé intérieur 224d du module inférieur 226.The cylinder 242 (relatively rigid) forming the working end of the suction pipe 240 is connected to the remainder of the suction pipe 240 (more flexible) by a rapid coupling type fastener 241. This cylinder 242 is disposed along this lower module 226, being retained by a ring 227 mounted on an extension 225 of the inner profile 224d of the lower module 226.

Pour permettre le détachement du tuyau d'aspiration 240, on comprend que le cylindre 242 est apte à sortir du fourreau 243 : dans cette position sortie, le cylindre 242 et de façon générale le tuyau d'aspiration 240, est retenu au bras de support et de guidage 202 uniquement le long de la partie horizontale 210, du module supérieur 221 et du module intermédiaire 224 de la partie verticale 220 (voir figure 5), par les éléments roulants 206 et par la cloche de protection 260 à l'intérieur de laquelle passe le tuyau d'aspiration 240 qui reste à l'extérieur des profilés 224a à 224d.To allow detachment of the suction pipe 240, it is understood that the cylinder 242 is able to exit the sleeve 243: in this extended position, the cylinder 242 and generally the suction pipe 240, is retained at the support arm and guide 202 only along the horizontal portion 210, the upper module 221 and the intermediate module 224 of the vertical portion 220 (see figure 5 ), by the rolling elements 206 and the protective bell 260 inside which the suction pipe 240 which is outside the profiles 224a to 224d passes.

Les opérations de montée (descente) du tuyau d'aspiration 240 par les troisièmes moyens d'entraînement 222 permettent également de sortir (rentrer) le cylindre 242 du tuyau d'aspiration 240 hors (dans) du (le) fourreau 243, ce dernier pouvant présenter (variante non représentée) un tronçon supérieur évasé. Le fourreau 243 est un cylindre de diamètre variable entre un maximum autorisant le dégagement (l'entrée) du cylindre 242 et un minimum bloquant par serrage le cylindre 242 par rapport au fourreau 243.The raising (lowering) operations of the suction pipe 240 by the third drive means 222 also make it possible to out (enter) the cylinder 242 of the suction pipe 240 out of (the) the (the) sleeve 243, the latter may have (variant not shown) a flared upper section. The sheath 243 is a cylinder of variable diameter between a maximum allowing the clearance (the inlet) of the cylinder 242 and a minimum blocking by clamping the cylinder 242 relative to the sheath 243.

Le repérage de la position verticale relative entre le cylindre 242 et le fourreau 243 est réalisé par un indexage à glissière entre un (ou plusieurs) picot(s) 246 et une (ou plusieurs) rainure(s) verticale(s) 227a traversant la paroi de la bague (voir les figures 7 à 10).The identification of the relative vertical position between the cylinder 242 and the sheath 243 is made by sliding indexing between one (or more) pin (s) 246 and one (or more) vertical groove (s) 227a passing through the wall of the ring (see Figures 7 to 10 ).

Egalement, il est possible d'orienter radialement la position du tuyau d'aspiration 240 autour de la partie verticale 220 du bras, et plus précisément de la partie verticale du manchon souple 226a et de la partie verticale du tuyau de nettoyage 230. A cet effet , comme on le voit sur les figures 7 à 10, la prolongation 225 est équipée de deux rainure horizontales 225a traversant sa paroi sur un angle au centre d'environ 180° (ce qui permet un réglage entre +90° et -90°), et qui coopèrent avec d'autre éléments saillants (non visibles sur les figures) de la bague 227.Also, it is possible to orient radially the position of the suction pipe 240 around the vertical part 220 of the arm, and more precisely of the vertical part of the flexible sleeve 226a and the vertical part of the cleaning pipe 230. effect, as we see on the Figures 7 to 10 , the extension 225 is equipped with two horizontal grooves 225a passing through its wall at a center angle of about 180 ° (which allows adjustment between + 90 ° and -90 °), and which cooperate with other projecting elements ( not visible in the figures) of the ring 227.

Un embout 244 est fixé sur l'extrémité libre du fourreau 243 et sert de filtre pour les matières aspirées par le cylindre 242.A tip 244 is fixed on the free end of the sleeve 243 and serves as a filter for the material sucked by the cylinder 242.

Également, grâce à la deuxième articulation à pivot 223c entre le module supérieur 221 et le module intermédiaire 224, on comprend qu'il est possible d'orienter radialement autour d'un axe vertical la position du module intermédiaire 224 et donc du module inférieur 226, ce qui permet d'obtenir une plus grande précision pour la position de tous les équipements du module inférieur 226, et en particulier de l'embout 244 du tuyau d'aspiration 240 ainsi que de la tête de curage 234 du tuyau de nettoyage 230.Also, thanks to the second pivot joint 223c between the upper module 221 and the intermediate module 224, it is understood that it is possible to orient radially around a vertical axis the position of the intermediate module 224 and therefore the lower module 226 , which makes it possible to obtain greater precision for the position of all the equipment of the lower module 226, and in particular of the nozzle 244 of the suction pipe 240 as well as of the cleaning head 234 of the cleaning pipe 230 .

Il faut comprendre que la tête de curage 234 peut être déployée au-delà du module inférieur 226, et en particulier en dehors du manchon 226a car le tuyau de nettoyage 230 est associé à un dévidoir motorisé (non représenté) situé sur le véhicule 100.It should be understood that the cleaning head 234 can be deployed beyond the lower module 226, and in particular outside the sleeve 226a because the cleaning pipe 230 is associated with a motorized reel (not shown) located on the vehicle 100.

Enfin, l'unité mobile 200 comporte également une cloche de protection mobile 260 entourant le module intermédiaire 224 et qui, lorsque le module inférieur 226 est déployé dans la bouche d'égout 300, descend au dessus du regard d'égout, de façon à protéger l'opérateur. Avantageusement, cette cloche 260 comporte une portion de paroi transparente dans la partie supérieure afin de pouvoir visualiser les opérations se déroulant dans la bouche d'égout 300.Finally, the mobile unit 200 also comprises a movable protection bell 260 surrounding the intermediate module 224 and which, when the lower module 226 is deployed in the manhole 300, goes down over the manhole, so as to protect the operator. Advantageously, this bell 260 comprises a portion of transparent wall in the upper part in order to be able to visualize the operations taking place in the manhole 300.

La partie verticale 220 comprend en outre, dans un boîtier (non représenté) monté à l'intérieur de la cloche de protection 260, un module caméra (non représenté) apte à sortir du boîtier précité afin de visualiser, l'état de la bouche d'égout 300 avant et/ou après son nettoyage comprenant le lavage sous un jet d'eau à haute pression transmis par la tête de curage 234, puis une aspiration depuis l'embout 244 du tuyau d'aspiration 240. A cet effet, un tel module caméra comporte son propre système de commande et son propre système de mise en mouvement lui permettant de se déplacer depuis la cloche 260 vers et/ou dans la bouche d'égout 300, indépendamment des mouvements de la partie verticale 220 du bras 202.The vertical portion 220 further comprises, in a housing (not shown) mounted inside the protection bell 260, a camera module (not shown) able to exit the aforementioned housing in order to visualize the state of the mouth 300 sewer before and / or after cleaning including washing under a high-pressure water jet transmitted by the cleaning head 234, then suction from the nozzle 244 of the suction pipe 240. For this purpose, such a camera module has its own control system and its own movement system allowing it to move from the bell 260 to and / or into the manhole 300, independently of the movements of the vertical portion 220 of the arm 202 .

Pour compléter ces premiers moyens de visualisation, l'unité mobile 200 peut comprendre en outre un support (non représenté) escamotable sur lequel peut être placé une caméra mobile formant un engin détachable du module inférieur 226 pouvant aller examiner et contrôler l'état du réseau au-delà de l'emplacement de la bouche d'égout 300.To complete these first display means, the mobile unit 200 may further comprise a retractable support (not shown) on which may be placed a mobile camera forming a detachable machine of the lower module 226 able to go and examine the state of the network beyond the location of the 300 manhole.

L'unité mobile 200 comporte un système de commande de tous les équipements mobiles, en particulier des premiers, deuxièmes, troisièmes et quatrièmes moyens d'entraînement du bras de support et de guidage 202, mais aussi du tuyau d'aspiration 240, du tuyau de nettoyage 230, du module caméra et de l'éventuel support de caméra mobile.The mobile unit 200 comprises a control system of all the mobile equipment, in particular first, second, third and fourth drive means of the support and guide arm 202, but also the suction pipe 240, the pipe 230, the camera module and any mobile camera support.

De ce qui précède, on comprend qu'au niveau du bras de support et de guidage 202, les éléments permettant la rotation du module intermédiaire 224 et du module inférieur 226 sont disposés au niveau de la partie supérieure de l'ensemble des trois modules 221, 224 et 226 du bras de support et de guidage 202. De cette façon, on évite de disposer des éléments mécaniques, en particulier des éléments mécaniques mobiles, encombrants dans la partie du bras de support et de guidage 202 qui va se positionner dans le regard d'égout 300.From the foregoing, it will be understood that at the level of the support and guide arm 202, the elements allowing the rotation of the intermediate module 224 and the lower module 226 are arranged at the level of the upper part of the set of three modules 221. , 224 and 226 of the support arm and guide 202. In this way, it is avoided to have mechanical elements, in particular moving mechanical elements, bulky in the portion of the support arm and guide 202 which will be positioned in the 300 manhole

De plus, on a placé dans le module inférieur 226 du bras de support et de guidage 202 uniquement les éléments techniques indispensables (notamment mécaniques) à cet emplacement pour éviter qu'ils ne soient soumis aux contraintes de saleté, d'humidité ou des chocs susceptibles de se présenter lors du fonctionnement à l'intérieur du regard.In addition, the lower module 226 of the supporting and guiding arm 202 has only the necessary technical (including mechanical) elements at this location to prevent them from being subjected to the stresses of dirt, moisture or shocks. likely to occur during operation inside the eye.

Les cuves destinées à contenir d'une part l'eau propre pour le jet sous haute pression (citerne d'eau) et d'autre part les boues et eaux sales aspirées par le tuyau d'aspiration (réservoir de collecte) peuvent être formées par une seule cuve 110 présentant une cloison de séparation, déplaçable ou non.Tanks intended to contain, on the one hand, clean water for the high-pressure jet (water tank) and, on the other hand, sludge and dirty water sucked by the suction pipe (collection tank) can be formed by a single tank 110 having a partition wall, movable or not.

Alternativement, la citerne d'eau est séparée du réservoir de collecte, ce dernier pouvant être équipé d'un piston éjecteur pour faciliter sa vidange.Alternatively, the water tank is separated from the collection tank, the latter can be equipped with an ejector piston to facilitate its emptying.
