Description
La présente invention concerne un nouveau procédé, concretisé par une installation permettant l'exploitation de l'énergie des vagues des mers. The present invention relates to a new process, embodied by an installation allowing the exploitation of the energy of sea waves.
Les installations de ce genre, proposées jusqu' présent, n'ont pas suscité assez d'intérêt, pout être appliquées à l'echel- le industrielle, à cause des conditions spéciales que leur exploitation implique. The installations of this kind, proposed until now, have not aroused enough interest, to be applied to the industrial scale, because of the special conditions which their exploitation implies.
A ce sujet on peut citer les installations qui nécessitent l'utilisation d'éléments spéciaux (des petites turbines, des pompes, des bobines d'induction, etc.) ou qui fonctionnent uniquement avec des vagues larges et reguliéres, ce qui fait que leur application soit difficile et non competitive. On this subject we can cite the installations which require the use of special elements (small turbines, pumps, induction coils, etc.) or which operate only with large and regular waves, which means that their application is difficult and not competitive.
L'installation qui fait l'objet de cette invention permet d'éviter tous ces inconvéniences parce qu'elle utilise des moyens très simples, faciles à réaliser et peu couteux. The installation which is the subject of this invention makes it possible to avoid all these drawbacks because it uses very simple means, easy to produce and inexpensive.
Le procédé prend en compte toute variation du niveau de l'eau, dans un point quelconque, pendant l-a houle, et se base sur le fait que le mouvement d'un flotteur, obligé à se deplacer seulement sur la direction verticale, peut être assimilé à un piston, dont le déplacement linéaire est facilement transformé en mouvement de rotation. Un tel flotteur-piston et le système de transmission de soh mouvement, constituent l'essentiel de l'installation, qui sera appelée par la suite "cellule énergétique. The process takes into account any variation in the water level, at any point, during the swell, and is based on the fact that the movement of a float, forced to move only in the vertical direction, can be assimilated to a piston, whose linear movement is easily transformed into a rotational movement. Such a piston-float and the soh movement transmission system constitute the main part of the installation, which will be called hereinafter "energy cell.
Plusieures cellules énergétiques agissent sur un mêe axe, dont les rotations sont multipliées, tant qu'il est nécessaire et finnalement transmisses à un générateur de courant. Several energy cells act on the same axis, the rotations of which are multiplied, as long as it is necessary and finally transmitted to a current generator.
Un nombre convenable de cellules --énergétiques, soutenues par une ossature métallique, forme une poutre tridimensionnelle et constitue une unité énergétique independante, appelée "plate-forme énergétique". A suitable number of energetic cells, supported by a metallic framework, form a three-dimensional beam and constitute an independent energetic unit, called "energetic platform".
Enfin, ces plates-formes énergétiques, disposées en chaines ou réseaux, forment une Centrale Electrique Marine. Finally, these energy platforms, arranged in chains or networks, form a Marine Electric Power Plant.
Les dessins annexés et les notes explicatives suivantes précisent les détailles de l'installation. The attached drawings and the following explanatory notes give details of the installation.
Cette installation posséde comme élement prinCipal un corp flottant, appellé "flotteur" par la suite, agissant pratiquement comme un piston. This installation has as main element a floating body, called "float" thereafter, practically acting as a piston.
Pour des considerations techniques et économiques on a choisi les caractéristiques suivantes:
Le flotteur 1 est formé d'un cylindre en tole (ou matière plastique), d'un diamètre de 1,0 m (soit d'une section d'environ
2 0,8 i ) et d'une hauteur de 0,9 m, avec le fond inférieur en for- me de calotte sphérique et le fond superieur plat. Le poid du flotteur sera de 150 kg. Ce poid sera obtenu par lestage, par exemple avec de l'eau.For technical and economic considerations the following characteristics have been chosen:
The float 1 is formed by a sheet metal cylinder (or plastic), with a diameter of 1.0 m (or a section of approximately
2 0.8 i) and 0.9 m high, with the bottom bottom in the form of a spherical cap and the top flat bottom. The weight of the float will be 150 kg. This weight will be obtained by ballasting, for example with water.
Le -cylindre ainsi constitué est obligé de se mouvoir seulement verticalement, à l'aide des guides 2 fixés sur une ossature métallique 3 supportant l'ensemble. The cylinder thus formed is forced to move only vertically, using guides 2 fixed on a metal frame 3 supporting the assembly.
Un câble 4 assure la transformation de ce mouvement linéaire du flotteur, dans une rotation de l'axe 6. Le câble est fixé sur la partie supérieure du flotteur en A, il passe derrière le tambour 5 et dans la gorge de la poulie 7, située n la partie inférieure de l'instalation et se relie de nouveau au flotteur au point B. A cable 4 ensures the transformation of this linear movement of the float, in a rotation of the axis 6. The cable is fixed on the upper part of the float at A, it passes behind the drum 5 and in the groove of the pulley 7, located n the lower part of the installation and connects again to the float at point B.
Le tambour 5 entrène l'axe 6 seulement dans un seul sens du mouvement, à l'aide d'un levier à ressort, voir seulement le mouvement ascendant du flotteur. Un deuxième câble 4' et le tambour 5' entrènent aussi l'axe 6, mais seulement pour le mouvement descendant du flotteur. L'inversion du mouvement est assurée à l'aide de deux poulies auxiliaires 8 et 9. The drum 5 drives the axis 6 only in one direction of movement, using a spring lever, see only the upward movement of the float. A second cable 4 'and the drum 5' also enter the axis 6, but only for the downward movement of the float. The reversal of the movement is ensured using two auxiliary pulleys 8 and 9.
On peut également transformer le mouvement linéaire du flotteur 1 dans un mouvement de rotation de l'axe 6, à l'aide d'un système de cremaillère 12 et du guide 13. It is also possible to transform the linear movement of the float 1 into a rotational movement of the axis 6, using a rack system 12 and the guide 13.
L'axe 6, disposé horizontalement, passe à travers 10 ensembles décrits précèdemment, appellés "cellules énergétiques". Axis 6, arranged horizontally, passes through 10 assemblies described above, called "energy cells".
Chaque cellule contribue à la rotation de l'axe, en lui assurant ainsi, une certaine uniformité de mouvement.Each cell contributes to the rotation of the axis, thus ensuring it a certain uniformity of movement.
A l'une de ses extrémités, l'axe 6 entre dans un multiplicateur de rotations 10, couplé à un générateur de courant 11. At one of its ends, the axis 6 enters a rotation multiplier 10, coupled to a current generator 11.
Chaque cellule énergétique fonctionne dans des espaces re servies dans le cadre de l'ossature porteuse formée de poutrelles métalliques profilées, constituant par leur ensemble une poutre réticulée tridimensionnelle 14. Une telle poutre d'environ 40 m longueur, de 6 m largeur et de 4 m de hauteur, contiendra 160 cellules énergétiques soit deux générateurs de courant. Each energy cell operates in spaces re-used within the framework of the load-bearing framework formed of profiled metal beams, constituting as a whole a three-dimensional reticulated beam 14. Such a beam of approximately 40 m length, 6 m width and 4 m high, will contain 160 energy cells or two current generators.
Cette poutre tridimensionnelle est supportée à ses extrémites par des poteaux, encastrés dans le sol du fond de la mer, formant ainsi une unité independante ou une plate-forme énergétique. This three-dimensional beam is supported at its extremities by poles, embedded in the ground of the sea floor, thus forming an independent unit or an energy platform.
Un système automatique, ou semi-automatique, d'immersion de toute une plate-forme, constituera une protection en cas de tempête. An automatic or semi-automatic immersion system for an entire platform will provide protection in the event of a storm.
Ces plates-formes pourront etre assemblées en longues files, paralléles, orientées perpendiculairement à la rive. La distance entre ces files sera déterminée en fonction du degré d'amortisation de la vague à la suite du frottement contre les éléments components de l'instalation. Une distance de 15 à 20 m, entre deux files sera suffisante pour que l'énergie de la vague reste assez grande pour entrainer toutes les plates-formes suivantes. These platforms can be assembled in long, parallel lines, oriented perpendicular to the shore. The distance between these lines will be determined according to the degree of damping of the wave following the friction against the components of the installation. A distance of 15 to 20 m, between two lines will be sufficient for the energy of the wave to remain large enough to drive all of the following platforms.
Dans une autre variante, les poteaux de support des plates-formes sont remplacés par un système "d'encrages" flottants immerges à une profondeur suffisante pour les rendre insensibles aux mouvements de surface de l'eau Ceci permet le montage des plates-formes au large et aussi dans des regions avec des marées importantes. In another variant, the support posts of the platforms are replaced by a system of floating "inks" immersed at a sufficient depth to make them insensitive to the surface movements of the water. This allows the mounting of the platforms to the wide and also in areas with high tides.
Dans le cas courant d'une vague de 1,0 m de hauteur et d'une periode de 5 secondes, le flotteur ayant un poids de 150 kg et un déplacement de 2 x 1,0 m (une ascension et une descente) il en resulte une énergie utile de 150 x 2/5 = 60 kgm/sec. soit 0,6Kw. In the common case of a 1.0 m high wave and a 5 second period, the float having a weight of 150 kg and a displacement of 2 x 1.0 m (an ascent and a descent) the result is a useful energy of 150 x 2/5 = 60 kgm / sec. or 0.6Kw.
Dans une première estimation, on pourrait compter, comme suite, sur une production de 0,6 Kw par cellule occupant une surface de 1,25 m2 en plan, autrement dit on obtient, aproximative 2 ment, 1,0 Kw pour tous les 2,5 m
D'autre part, si on considère une consommation de 100 kg d'acier par cellule, il résulte un investissement de 5000 Fr, environ, pour un Kw., tout en considérant que l'entretien est de même ordre de grandeur que pour toutes les constructions industrielles. In a first estimate, we could count, as a result, on a production of 0.6 Kw per cell occupying an area of 1.25 m2 in plan, in other words we obtain, aproximatively 2 ment, 1.0 Kw for both .5 m
On the other hand, if we consider a consumption of 100 kg of steel per cell, it results in an investment of 5000 Fr, approximately, for a Kw., While considering that the maintenance is of the same order of magnitude as for all industrial constructions.
