Abstract

The installation uses wave energy to compress air, then passes the compressed air through a turbine which in turn drives an electric generator (11). A reinforced concrete dam (1) is placed across a stream of turbulent water. The dam has oblong channels (2) with one way control valves (5) at the end further from the water. A large closed chamber behind the wall (6) acts as an air reservoir in which the flow of the waves through (9) the chamber causes pressure variation. A valve (10) at the top of the chamber allows compressed air to reach a turbine driving a generator (11).

Description

La pressente invention concerne les dispositifs du type houlomoteur,servant à récupérer l'énergie des vagues. The present invention relates to wave-type devices, used to recover wave energy.

Les dispositifs connus de ce genre se décomposent en trois familles:
-les systèmes flottants,très vulnérables lors des tempêtes
-les systèmes sous-marins moins vulnérable,mais d'un rendement souvent moins bon.Ces deux systèmes ont des difficultés en commun,l'encrage et le transport de l'énergie produite.Known devices of this kind are broken down into three families:
-floating systems, very vulnerable during storms
-submarine systems less vulnerable, but often less efficient.These two systems have difficulties in common, inking and transporting the energy produced.

La troisième famille concerne les dispositifs construits sur le fond et dépassant de l'eau.Dans les dispositifs connus de ce genre tous sont tributaires des marées et dans les meilleurs cas la moitiés de l'énergie des vagues est utilise à pousser de L'eau dans un réservoir en hauteur afin de faire fonctionner une turbine. The third family concerns the devices built on the bottom and protruding from the water. In known devices of this kind all are dependent on the tides and in the best cases half of the energy of the waves is used to push water in a high tank to operate a turbine.

Le dispositif selon l'invention remédie à ces deux inconvénients.Eh effet une jetée en béton dans laquelle des lumières oblongues alignées parallèlement à la surface de l'eau sont disposees au-dessus les unes des autres. Chaque rangée de lumière est décalée par rapport à sa voisine d'une demie lumière. The device according to the invention overcomes these two drawbacks. Indeed a concrete pier in which oblong lights aligned parallel to the surface of the water are arranged above each other. Each row of light is offset from its neighbor by half a light.

Ces lumières légèrement coniques dans le sens de la longueur traversent le mur de béton et débouchent dans un réservoir contenant l'air comprimé et l'eau des vagues.Le trop plein de l'eau est évacué vers les eaux calme grâce an principe des vases communiquants par un canal situé au fond du réservoir.These lights slightly conical in the direction of the length cross the concrete wall and emerge in a tank containing the compressed air and the water of the waves. The overflow of the water is evacuated towards the calm waters thanks to the principle of the vases communicating through a channel located at the bottom of the tank.

L'air ne peut s'échapper par le chemin d'arrivée,car par sa propre force il obstrue l'orifice avec un volume cylindrique en matière clastique maintenu en position grâce à une cage L'air se dirige vers la vanne de régulation alimentant soit un réseau pneumatique,soit un gsnérateur de courant. Après le passage dans le gAnérateur l'air est évacué du côté vague de la jetée par un tuyau sinusoidaze dont l'axe est oblique par rapport à l'axe de la digue.Pour obtenir un meilleur résultat on peut faire varier la pression dans le rdser- voir d'air comprimé.Pour améliorer le rendement de l'installation,une cuve d'eau morte et une citerne d'air comprimé peuvent entre aménagés pour chaque niveau.Ceci permettant de récupérer l'air à la pression de chaque niveau de vague,assurant ainsi un maaiium de rendement.L'Eir comprimé obtenu peut etre utilisé tel quel,mais lors des têmpête ,une partie peut être surcompressée grâce à l'autre partie, ceci permettant de ctocker aux pertes près la même quantité d'énergie dans un volume restreint.Cette énergie pouvant entre utilisée pour palier aux jours sans vague.Sur cette digue pouvant abriter un port est construit un quai. The air cannot escape by the arrival path, because by its own force it obstructs the orifice with a cylindrical volume of clastic material held in position thanks to a cage The air goes to the regulating valve supplying either a pneumatic network or a current generator. After passing through the gAnerator the air is evacuated on the vague side of the jetty by a sinusoidaz tube whose axis is oblique to the axis of the dyke. To obtain a better result you can vary the pressure in the compressed air tank. To improve the efficiency of the installation, a dead water tank and a compressed air tank can be fitted for each level. This makes it possible to recover air at the pressure of each level. wave, thus ensuring a maaiium of output. The compressed air obtained can be used as it is, but during the storm, a part can be overcompressed thanks to the other part, this making it possible to ctock at losses almost the same amount of energy in a limited volume. This energy which can be used to compensate for days without waves. On this dike which can shelter a port is built a quay.

Les dessins annexés sont une vue de face côté mer et une coupe  X A.  The accompanying drawings are a front view on the sea side and a section  X A.

Tel qu'il est représenté le dispositif est formé d'une structure I dans laquelle sont ménagés des canneaux oblongs et légèrement coniques 2.Du côté vagues une pente d'accès 3 facilite l'entrée des vagues.La pente 4 compense la perte d'énergie des petites vagues. La valve en caoutchouc 5 obstrue l'entrée de 2 après le passage de chaque vague à la pression ambiante de la citerne 6.La valve 5 est maintenue en position de fonctionnement par la grille 7.L' eau des vagues tombe dans le bassin 8 avant d'être évacué par le canal 9.As shown, the device is formed by a structure I in which are oblong and slightly conical channels 2. On the wave side an access slope 3 facilitates the entry of waves. The slope 4 compensates for the loss of energy of small waves. The rubber valve 5 obstructs the entry of 2 after the passage of each wave at the ambient pressure of the tank 6. The valve 5 is maintained in the operating position by the grid 7. The water from the waves falls into the basin 8 before being evacuated through channel 9.

L'air comprimé passe par la valve de régulation 10 puis à travers un générateur d'électricité Il et est évacué par le canal sinusoïdale I2.Lorsque la consommation d'énergie est inférieure à la production,l'air peut être acheminé vers un réservoir de stockage par le canal I3,c'est grâce à ce même canal que la pression de la citerne 6 est réglée en fonction de la puissance des vagues.The compressed air passes through the regulation valve 10 then through an electricity generator Il and is evacuated by the sinusoidal channel I2. When the energy consumption is less than the production, the air can be routed to a tank storage by channel I3, it is thanks to this same channel that the pressure of tank 6 is adjusted according to the power of the waves.

Le dispositif objet de 1' invention peut être utilisé sur toutes les côtes et sur tous les hauts fonds où il y a des vagues. Il s'intègre bien dans les digues ou jetées et particulièrement pour former un port ,un endroit qui a besoin d'énergie et dont il est nécessaire qu'il ait des digues,ce qui diminue le cotit de fabrication. The device which is the subject of the invention can be used on all coasts and on all shallows where there are waves. It fits well in dikes or jetties and particularly to form a port, a place that needs energy and which it is necessary that it has dikes, which reduces the cost of manufacture.

E.D.P. Il est bien entendu que la présente invention peut être exploitée tel que décrite et représentée ou en partie.Cette description représente un ex emple auquel de nombreuses modifications peuvent entre apportées sans que l'on s'écarte de la présente invention.
