Description

Die Erfindung betrifft eine Vorrichtung zur Reinigung von Straßenoberflächen gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a device for cleaning road surfaces according to the preamble of claim 1.

Die maschinelle Reinigung von Straßen, Gehwegen und anderen Flächen wird üblicherweise mit selbstfahrenden Reinigungsvorrichtungen durchgeführt. Ein wesentlicher Bestandteil solcher Vorrichtungen ist eine Saugeinrichtung, mit der loser Schmutz in einen Sammelbehälter eingesaugt werden kann, der zur Entsorgung entleert wird. Die eingesaugte Luftmenge muss nach einer entsprechenden Reinigung wieder an die Umwelt abgegeben werden. Dies erfolgt üblicherweise an der Unterseite des Fahrzeuges, was jedoch den Nachteil hat, dass eventuell verbleibender Schmutz aufgewirbelt wird, was naturgemäß äußerst unerwünscht ist.The mechanical cleaning of roads, sidewalks and other surfaces is usually done with self-propelled cleaning devices. An essential component of such devices is a suction device, with the loose dirt can be sucked into a sump, which is emptied for disposal. The amount of air sucked in must be returned to the environment after proper cleaning. This is usually done on the underside of the vehicle, but this has the disadvantage that any remaining dirt is whirled up, which is naturally extremely undesirable.

Um diesen Nachteil zu vermeiden, sind Reinigungsvorrichtungen bekannt geworden, die eine Luftausströmung an der Oberseite aufweisen. Solche Vorrichtungen sind beispielsweise in der EP 0 261 553 A oder der EP 0 234 782 A offenbart. Eine Luftausströmung dieser Art besitzt jedoch den Nachteil, dass sich Schallemissionen ungehindert ausbreiten können, so dass solche Vorrichtungen sehr problematisch im Hinblick auf die Lärmemission sind.To avoid this disadvantage, cleaning devices have become known which have an outflow of air at the top. Such devices are disclosed, for example, in EP 0 261 553 A or EP 0 234 782 A. However, an air outflow of this type has the disadvantage that sound emissions can propagate unhindered, so that such devices are very problematic in terms of noise emission.

Aufgabe der vorliegenden Erfindung ist es, diese Nachteile zu vermeiden und eine Vorrichtung anzugeben, die sowohl eine schonende Ausströmung der angesaugten Luft ermöglicht als auch ein möglichst geringes Arbeitsgeräusch aufweist. Dabei soll zusätzlich eine möglichst geringe Emission von Staub oder anderen Teilchen durch die ausströmende Luft gewährleistet werden und es sollen möglichst große Wartungsintervalle erreicht werden.Object of the present invention is to avoid these disadvantages and to provide a device which allows both a gentle outflow of the sucked air and has the lowest possible working noise. In addition, the lowest possible emission of dust or other particles is to be ensured by the outflowing air and as long as possible maintenance intervals should be achieved.

Diese Aufgaben werden erfindungsgemäß durch die Merkmale von Patentanspruch 1 gelöst.These objects are achieved by the features of claim 1.

Wesentlich an der vorliegenden Erfindung ist die Erkenntnis, dass eine bedeutsame Geräuschreduktion dadurch erreicht werden kann, dass eine großvolumige Ausströmkammer vorgesehen wird, in der eine möglichst laminare Strömung erzielt wird oder zumindest die Turbulenzen, die von der aus der Saugturbine ausgestoßener mitgeführt werden, abklingen können. Wichtig in diesem Zusammenhang ist das Zusammenwirken mit einem Diffusor, der die Strömungsgeschwindigkeit verringert und zusätzlich eine Leistungssteigerung ermöglicht. Durch die räumliche Anordnung der Ausströmkammer oberhalb des Sammelbehälters wird in besonders vorteilhafter Weise erreicht, dass die Ausströmkammer flach und großflächig ausgebildet werden kann was die Wirksamkeit zusätzlich erhöht. Außerdem lässt sich auf diese Weise ein einfacher konstruktiver Aufbau der Vorrichtung erreichen.Essential to the present invention is the recognition that a significant noise reduction can be achieved by providing a large-volume outflow chamber in which the most laminar flow is achieved or at least the turbulence emitted by the ejected from the suction turbine be carried along, can subside. Important in this context is the interaction with a diffuser, which reduces the flow velocity and also allows an increase in performance. Due to the spatial arrangement of the outflow chamber above the collecting tank is achieved in a particularly advantageous manner that the outflow chamber can be formed flat and large area which additionally increases the effectiveness. In addition, a simple structural design of the device can be achieved in this way.

Besonders günstig ist es im Rahmen der Erfindung, wenn die Ausströmkammer in Draufsicht im Wesentlichen rechteckig ist und eine in Längsrichtung kontinuierlich abnehmende Querschnittsfläche aufweist. Seitlich gesehen, ist die Ausströmkammer bei dieser Ausführung keilförmig, so dass bei gleichmäßiger Verteilung der Ausströmöffnungen eine näherungsweise gleichmäßige Strömungsgeschwindigkeit im Inneren der Ausströmkammer erreicht, wird, was sich vorteilhaft auf die Geräuschemission auswirkt.It is particularly favorable in the context of the invention, when the outflow chamber is substantially rectangular in plan view and has a continuously decreasing in the longitudinal direction cross-sectional area. Seen from the side, the outflow chamber is wedge-shaped in this embodiment, so that, with a uniform distribution of the outflow openings, an approximately uniform flow velocity in the interior of the outflow chamber is achieved, which has an advantageous effect on the noise emission.

Besonders günstige Strömungsverhältnisse können dadurch erreicht werden, dass der Diffusor vollflächig in eine Stirnfläche der Ausströmkammer mündet. Dadurch werden insbesondere störende Druckverluste vermieden und Turbulenzen verhindert. Eine Entlüftung des Aggregatraums kann dadurch erreicht werden, dass die Ausströmleitung über einen Injektor in den Diffusor mündet.Particularly favorable flow conditions can be achieved in that the diffuser opens over its entire surface into an end face of the outflow chamber. As a result, in particular disturbing pressure losses are avoided and prevents turbulence. Venting of the aggregate space can be achieved by opening the discharge line via an injector into the diffuser.

Eine weitere wesentliche Reduktion der Geräuschemission kann dadurch erreicht werden, dass in der Ausströmkammer ein parallel zu einer die Ausströmöffnungen enthaltenden Oberfläche ein Schalldämpfer angeordnet ist. Insbesondere ist dieser Schalldämpfer als Jalousie ausgebildet. Es sind jedoch auch andere Konstruktionen, wie etwas parallel zu der Oberfläche verlaufende Profile möglich. Wesentlich ist, dass die Ausströmkammer durch den im Wesentlich waagrecht verlaufenden Schalldämpfer in einen oberen Abschnitt und einen unteren Abschnitt unterteilt wird, so dass sich allfällige resonante Schwingungen nicht bis zu den Ausströmöffnungen ausbreiten können. Eine weitere besonders bevorzugte Ausführungsvariante der Erfindung sieht vor, dass in der Ausströmkammer parallel zu einer die Ausströmöffnungen enthaltenden Oberfläche ein Filter angeordnet ist. Auf diese Weise ist es möglich, ein extrem großflächiges Filter zu verwenden, das entsprechend gering belastet ist, so dass große Wartungsintervalle erreicht werden.A further substantial reduction of the noise emission can be achieved by arranging a silencer in the outflow chamber parallel to a surface containing the outflow openings. In particular, this silencer is designed as a blind. However, other constructions, such as profiles parallel to the surface, are possible. It is essential that the outflow chamber is subdivided by the essentially horizontally extending muffler into an upper section and a lower section, so that any resonant vibrations can not propagate to the outflow openings. A further particularly preferred embodiment variant of the invention provides that a filter is arranged in the outflow chamber parallel to a surface containing the outflow openings. In this way, it is possible to use an extremely large-area filter, which is correspondingly low load, so that large maintenance intervals are achieved.

Im Zusammenhang mit der vorliegenden Erfindung ist es aus konstruktiven Gründen besonders günstig, wenn seitlich des Sammelbehälters Wassertanks vorgesehen sind. Auf diese Weise kann neben einer konstruktiven Vereinfachung auch eine besondere Stabilität im Fahrverhalten von selbstfahrenden Vorrichtungen erreicht werden, da Schwerpunktverlagerungen durch Strömungen innerhalb der Wassertanks aufgrund ihrer geringen Abmessungen in Querrichtung weitgehend vermieden werden können.In connection with the present invention, it is particularly favorable for design reasons, if water tanks are provided laterally of the collecting container. In this way, besides a constructive simplification Also, a special stability in the handling of self-propelled devices can be achieved, since center of gravity shifts can be largely avoided by currents within the water tank due to their small dimensions in the transverse direction.

Fig. 1 zeigt ein Fahrzeug 1, das eine erfindungsgemäße Vorrichtung trägt, die aus einem Sammelbehälter 2 besteht, der über eine Saugleitung 3 mit einer Saugöffnung 4 in Verbindung steht, die knapp über der Straßenoberfläche 7 geführt wird, um Schmutz und Staub aufzusaugen. In Fig. 1 ist die Saugöffnung zwischen den Achsen 8, 9 des Fahrzeugs angeordnet, es ist jedoch im Rahmen der Erfindung gleichermaßen möglich, die Saugöffnung an anderen Stellen, beispielsweise vor der Vorderachse 8 vorzusehen, um vom Fahrerhaus 5 aus die Funktion der Saugöffnung 4 beobachten zu können.Fig. 1 shows a vehicle 1, which carries a device according to the invention, which consists of a collecting container 2, which communicates via a suction line 3 with a suction port 4, which is guided just above the road surface 7 to absorb dirt and dust. In Fig. 1, the suction opening between the axles 8, 9 of the vehicle is arranged, however, it is equally possible within the scope of the invention to provide the suction opening at other locations, for example in front of the front axle 8, from the cab 5, the function of the suction opening 4th to be able to watch.

Das Fahrzeug besitzt weiters in an sich bekannte Weise rotierende Bürsten 6 und andere nicht dargestellte Reinigungsgeräte.The vehicle further has in known manner rotating brushes 6 and other cleaning devices, not shown.

Fig. 2 zeigt den Aufbau des Sammelbehälters 2 im Detail. Dieser ist durch ein Schott 10 in einen Sammelabschnitt 12 und in einen Aggregatabschnitt 11 unterteilt. Im Aggregatabschnitt 11 ist eine Saugturbine 13 vorgesehen, die von einem Motor 14 angetrieben ist. Über ein als Grobfilter ausgebildetes Leitblech 25, das sich im Wesentlichen horizontal im oberen Bereich des Sammelabschnitts 12 erstreckt, wird die Luft aus dem Sammelabschnitt 12 angesaugt. Stromabwärts der Saugturbine 13 ist eine Ausströmleitung 19 angeordnet, die in einen Ejektor 24 mündet, der in einen Diffusor 15 übergeht, der die Wirkung der Saugturbine 13 durch die Verzögerung des Luftstroms verstärkt. Der Ejektor 24 dient zur Entkoppelung des Körperschalls der Saugturbine 13 und zur Entlüftung des Aggregatabschnitts. Über eine Düse 16 wird der Luftstrom in eine Ausströmkammer 17 eingeblasen, die sich großflächig oberhalb des Sammelabschnitts 12 erstreckt. Über Ausströmöffnungen 18 wird die Luft aus dem Sammelbehälter 2 ausgeblasen. In Längsrichtung weist die Ausströmkammer 17 eine nach hinten abnehmende Querschnittsfläche auf.Fig. 2 shows the structure of the collecting container 2 in detail. This is divided by a bulkhead 10 into a collecting section 12 and into an aggregate section 11. In the unit section 11, a suction turbine 13 is provided, which is driven by a motor 14. The air is sucked out of the collecting section 12 via a baffle 25 designed as a coarse filter, which extends substantially horizontally in the upper region of the collecting section 12. Downstream of the suction turbine 13, an outflow line 19 is arranged, which opens into an ejector 24, which merges into a diffuser 15, which amplifies the effect of the suction turbine 13 by the delay of the air flow. The ejector 24 serves to decouple the structure-borne noise of the suction turbine 13 and to vent the unit section. Via a nozzle 16, the air flow in an outflow chamber 17 injected, which extends over a large area above the collecting portion 12. About discharge openings 18, the air is blown out of the sump 2. In the longitudinal direction, the outflow chamber 17 has a rearwardly decreasing cross-sectional area.

In Fig. 3 ist der Querschnitt der Ausströmkammer 17 im Detail dargestellt. Auf Verbindungsstäben 19, die sich in Längsrichtung des Fahrzeugs erstrecken, sind senkrecht angeordnete Lamellen 20 angeordnet, die dazu dienen, den Luftstrom gleichmäßig und möglichst frei von Turbulenzen zu machen, wodurch diese Anordnung als Schalldämpfer 22 dient. Oberhalb des Schalldämpfers 22 ist ein Filter 23 angeordnet, der als Gewebefilter und/oder als Drahtgeflecht ausgebildet ist.In Fig. 3, the cross section of the outflow chamber 17 is shown in detail. On connecting rods 19, which extend in the longitudinal direction of the vehicle, vertically arranged lamellae 20 are arranged, which serve to make the air flow uniform and as free as possible of turbulence, whereby this arrangement serves as a muffler 22. Above the muffler 22, a filter 23 is arranged, which is designed as a fabric filter and / or as a wire mesh.

Aus Fig. 4 ist ersichtlich, dass seitlich des Sammelabschnitts 12 Wassertanks 21 angeordnet sind.From Fig. 4 it can be seen that 12 water tanks 21 are arranged laterally of the collecting portion.

Fig. 5 zeigt die Ausströmkammer 17 in Ansicht von oben mit dem über die ganze Breite über die Einströmdüse 16 vorgeschalteten Diffusor 15. Der Diffusor wird von der Ausströmleitung 19 durch den Ejektor 24 angeströmt.FIG. 5 shows the outflow chamber 17 in a view from above with the diffuser 15 connected upstream across the inlet nozzle 16. The diffuser is flown by the discharge line 19 through the ejector 24.
