Abstract

Wave motion in the sea is used to pump water to a shore based storage tank in which a layer of gas is compressed above the rising water to assist in forcing the water through a turbine. Some of the turbine output power may be used to pump water to a storage at a level above the turbine to provide energy during calm sea periods. A float on the sea surface operates, via a rope and pulley, arrangement, the push rod of the pump which has a valved piston at its end. A submerged float acts as a counterweight to restore the piston. As the piston reciprocates water is forced up a pipe to a closed storage tank and supplied to a turbine. A water storage above the turbine can supplement the water flow.

Description

La présente invention a pour objet un moteur marin et, plus particulièrement, un dispositif produisant de l'énergie à partir de la houle marine et des vagues. The present invention relates to a marine engine and, more particularly, a device producing energy from sea swell and waves.

Le dispositif, selon la présente invention, est constitué selon la fig. NO 1 par
- Un socle (1) fixé ou non au fond de la mer, qui fera réaction aux différentes forces exercées par des flotteurs (6) et (7).The device according to the present invention is constituted according to FIG. NO 1 per
- A base (1) fixed or not fixed to the bottom of the sea, which will react to the different forces exerted by floats (6) and (7).

- Un cylindre (2) dans lequel coulisse un piston (3) est fixé sur ce socle. - A cylinder (2) in which a piston (3) slides is fixed on this base.

L'ensemble comportant des clapets d'aspiration (4) et de refoulement (5) constitue une pompe à eau aspirante et refoulante, mouvement alternatif. The assembly comprising suction (4) and discharge (5) valves constitutes a suction and pressure water pump, reciprocating movement.

Un petit flotteur (7) immergé près de la pompe, exerce une tension sur le piston (3) pour le ramener en arrière, par l'intermédiaire d'un câble (18) et d'une poulie de renvoi (11) de façon à lui faire effectuer le cycle d'as- piration, lorsque le grand flotteur (6) descendra dans le creux de la houle. A small float (7) immersed near the pump, exerts a tension on the piston (3) to bring it back, by means of a cable (18) and a return pulley (11) so to make it perform the suction cycle, when the large float (6) descends into the hollow of the swell.

Ce grand flotteur (6) qui suit en surface les mouvements de la houle, est relié au piston (3) par un bras rigide (17), un câble (8), une poulie de renvoi (9) et un moufle (10). Lors de sa montée sur la crete de la houle, il tirera sur le piston pour lui faire exécuter le cycle de refoulement. This large float (6) which follows the movements of the swell on the surface, is connected to the piston (3) by a rigid arm (17), a cable (8), a deflection pulley (9) and a block (10) . When it rises on the crest of the swell, it will pull on the piston to make it execute the delivery cycle.

Cette pompe, ainsi constituée, refoulera l'eau aspirée dans un accumulateur (13) comportant un volume gazeux (14) par l'intermédiaire d'une canalisation (15). This pump, thus constituted, will discharge the water sucked into an accumulator (13) comprising a gas volume (14) via a pipe (15).

Le gaz, comprimé par l'eau, la maintiendra sous pression, de façon à alimenter des turbines (18) à l'aide de vannes pressostatiques (16), s'ouvrant au fur et à mesure de l'augmentation de pression, proportionnellement à l'aug- mentation du débit. The gas, compressed by the water, will keep it under pressure, so as to supply the turbines (18) using pressostatic valves (16), opening as the pressure increases, proportionally increase in flow.

I1 pourra etre constitué une batterie, d'un nombre important de pompes, reliées à un ou plusieurs réservoirs, ou alimentant un lac artificiel creusé sur une hauteur, à proximité de la-batterie. En choisissant un site approprié, exposé à la houle marine du grand large, et en implantant la batterie par 25 mètres de fond et plus, et suffisamment loin du rivage pour etre en dehors de la zone de ressac, nous pouvons obtenir une énergie très -im- portante pouvant alimenter une centrale hydrauélectrique classique, alimentée depuis le lac supérieur par une conduite forcée.  I1 could be constituted a battery, a large number of pumps, connected to one or more tanks, or supplying an artificial lake dug on a height, near the battery. By choosing an appropriate site, exposed to the sea swell of the open sea, and by implanting the battery by 25 meters of bottom and more, and sufficiently far from the shore to be outside the surf zone, we can obtain a very - important that can supply a conventional hydrauelectric power station, supplied from the upper lake by a penstock.

We could consider the construction of a hydroelectric power station on a shore well exposed to sea swell.

Un socle en béton de 80 m x 50 m et de 0.20 m d'épaisseur pourrait être coulé par 25 m de profondeur, suffisamment éloigné du rivage pour être en dehors de l'influence du ressac. Sur ce socle, pourrait être adaptée une batterie de 40 ensembles de pompage, par exemple 8 rangées dans la longueur, et 5 dans la largeur. A concrete base 80 mx 50 m and 0.20 m thick could be poured 25 m deep, far enough from the shore to be outside the influence of the surf. On this base, a battery of 40 pumping sets could be adapted, for example 8 rows in length, and 5 in width.

Ce socle pourrait résister à une traction de 1.000.000 kg, pour une poussée de 10.400 x 40 = 416.000 kg pour la totalité des flotteurs, s' ils montaient en même temps. Cette batterie serait reliée à 1 ou plusieurs accumulateurs. This base could withstand a traction of 1,000,000 kg, for a thrust of 10,400 x 40 = 416,000 kg for all the floats, if they were mounted at the same time. This battery would be connected to 1 or more accumulators.

On aurait, d'après notre hypothèse, une puissance moyenne de 60 x 40 = 2 400 CV ou 1.766 KVA
Maxim de 320 x 40 = 12 400CV ou 9 420 KVA.We would have, according to our hypothesis, an average power of 60 x 40 = 2,400 CV or 1,766 KVA
Maximum of 320 x 40 = 12,400CV or 9,420 KVA.

On se rend bièn compte que l'importance de la centrale n'est pas limitée à notre hypothèse et que l'on obtient ainsi une énergie renouvelable très bon marché, et non polluante De plus, les machines profondément immergées ne peuvent etre endommagées par les tempêtes. We realize that the importance of the plant is not limited to our hypothesis and that we thus obtain a very cheap, non-polluting renewable energy. In addition, the deeply submerged machines cannot be damaged by storms.

Les accumulateurs pourraient être remplacés par des lacs artificiels et, dans notre hypothese, à une centaine de mètres au-dessus du niveau de la mer. The accumulators could be replaced by artificial lakes and, in our hypothesis, a hundred meters above sea level.

En cas de niveaux de mer supérieurs à l'hypothèse (tempête exceptionnelle), les flotteurs A seraient seulement immergés sans autre contrainte supplémentaire sur les appareils immergés. In case of sea levels above the hypothesis (exceptional storm), the floats A would only be submerged without any other additional constraint on the submerged devices.
