Abstract

The energy expended in creating artificial waves and swells is recovered by holding the wave making ramp (1) between two floating pontoons (2,3) which may be ballasted such that upper edge of the tamp is level with the water surface. This is attached by two hinged lines (5,7) running across its width enclosing an 'S' shaped section (6). The upper hinge pivots along one edge of a reservoir (8). The reservoir moves between the pontoons maintaining a vertical position hold by pins (10) pivoted at each end. Turbo - generators (15,16) are driven by the reservoir contents via two conduits (13,14) attached to a shaft (17) between the pontoons. The conduits may be controlled by valves at their output ends. The energy recovery method may also be used in sea platforms, floating factories etc.

Description

Le présent additif se réfere à la demande de Brevet nO 79 14 850 déposée le 11 Juin 1979. Il a pour objet de décrire une centrale récuperant la force de la houle en utilisant l'énergie de vagues déferlentes artificiellement créées par cette centrale, comme dans le Brevet nO 79 14 850 mais suivant une autre variante de réalisation. This addendum refers to patent application No. 79 14 850 filed on June 11, 1979. Its purpose is to describe a power station recovering the force of the swell by using the energy of breaking waves artificially created by this power station, as in Patent No. 79 14 850 but according to another alternative embodiment.

Les vagues déferlentes artificielles sont toujours créées par un plan incliné (1) mais ce dernier au lieu d'être supporté par une structure fixe posée sur le fond, comme c'était le cas dans le Brevet ci-dessus, sert de liaison rigide à deux flotteurs identiques (2) et (3) avec lesquels il constitue une sorte de coque catamaran. Artificial breaking waves are always created by an inclined plane (1) but the latter instead of being supported by a fixed structure placed on the bottom, as was the case in the above patent, serves as a rigid connection to two identical floats (2) and (3) with which it constitutes a kind of catamaran hull.

Ces flotteurs peuvent être ballastés ou déballastés pour positionner le plan incliné (1) par rapport au niveau moyen de la mer de telle sorte que l'arête supérieure de ce plan incliné (1) affleure presque à ce niveau. Cette arête supérieure (4) est munie d'une charniere (5) sur laquelle vient s'articuler un tremplin galbé en forme de S (6). L'arête supérieure de ce tremplin vient à son tour s'articuler au moyen d'une charnière (7) sur le bord d'un réservoir (8) fixé sur un flotteur ballastable (9). These floats can be ballasted or deballasted to position the inclined plane (1) relative to the mean sea level so that the upper edge of this inclined plane (1) is almost flush with this level. This upper edge (4) is provided with a hinge (5) on which is articulated a shaped S-shaped springboard (6). The upper edge of this springboard in turn is articulated by means of a hinge (7) on the edge of a tank (8) fixed on a ballastable float (9).

Un levier (10) attaché d'un côté à un pivot (11) du flotteur (3) et de l'autre à un pivot (12) du flotteur (9), constitue avec le tremplin (6) une liaison déformable qui permet au réservoir (8) et au flotteur (9) qui le porte de rester toujours verticaux quel que soit le tirant d'eau du flotteur(9). A lever (10) attached on one side to a pivot (11) of the float (3) and on the other to a pivot (12) of the float (9), constitutes with the springboard (6) a deformable connection which allows to the tank (8) and to the float (9) which carries it to remain always vertical whatever the draft of the float (9).

Cette disposition permet le réglage en hauteur du bord (7) du tremplin et du réservoir en fonction de la hauteur de la houle. This arrangement allows the height adjustment of the edge (7) of the springboard and the reservoir as a function of the height of the swell.

Deux conduites au moins, (13) et (14), contenant en leur centre deux turbo-générateurs (15) et (16), permettent à l'eau accumulée dans le réservoir (8) de retourner à la mer après avoir fait tourner ces turbo-générateurs.  At least two pipes, (13) and (14), containing in their center two turbo-generators (15) and (16), allow the water accumulated in the tank (8) to return to the sea after having turned these turbo-generators.

Ces conduites sont montees fixes sur une traverse telle que (17) renforcant la liaison des flotteurs catamarans (2) et (3). Dans un mode de réalisation, elles débouchent dans le réservoir (8) à travers deux plaques verticales étanches (18) et (19) qui peuvent coulisser par rapport à la paroi arriere (22) du réservoir (8).  These pipes are fixedly mounted on a cross member such as (17) strengthening the connection of the catamaran floats (2) and (3). In one embodiment, they open into the tank (8) through two sealed vertical plates (18) and (19) which can slide relative to the rear wall (22) of the tank (8).

Deux vannes (20) et (21) permettent d'ouvrir ou de fermer l'arrière des conduites (13) et (14). Two valves (20) and (21) make it possible to open or close the rear of the pipes (13) and (14).

Suivant la quantité d'eau apportée dans le réservoir (8) par les vagues déferlentes on ouvre ou on ferme une au moins des vannes (20) ou (21). Depending on the amount of water brought into the tank (8) by the breaking waves, at least one of the valves (20) or (21) is opened or closed.

La centrale peut être ancrée par une ligne unifilaire en un point situé au milieu de l'arête inférieure de son plan incliné (23) ce qui lui permet de s' orienter automatiquement pour rester face à la direction de la houle. The unit can be anchored by a single line at a point located in the middle of the lower edge of its inclined plane (23) which allows it to orient itself automatically to stay facing the direction of the swell.

Le dispositif proposé est utilisable dans la récupération de l'ener- gie de la houle, et peut servir à alimenter soit des agglomérations sur le rivage, soit des installations sur plateformes en mer, tels des champs pétroliers ou des usines flottantes.  The proposed device is usable in recovering the energy of the swell, and can be used to supply either built-up areas on the shore, or installations on offshore platforms, such as oil fields or floating factories.
