Abstract

The wave energy converter has two independent volumes which are subject to variations of water pressure. The two volumes are assembled in one unit and submerged. Each volume is formed by a cylinder and piston. The piston is displaced by the difference between two pressures; the external pressure determined by the depth of water and a mechanically generated internal pressure that opposes the external pressure. The variation in depth as the waves rise and fall causes a reciprocating motion of the piston, which can be transmitted by hydraulic coupling to electric generators. An alternative configuration uses opposed pistons with air between them. USE - For conversion of wave energy to electrical energy.

Description

Le dispositif a pour but de capter l'énergie des vagues. Il est composé de volumes groupés et immergés, qui sont soumis à la pression de l'eau, qui varie de la verticale du sommet de la vague, à la verticale du creux de la vague. The device aims to capture the energy of the waves. It is composed of grouped and submerged volumes, which are subjected to the pressure of water, which varies from the vertical of the top of the wave, to the vertical of the trough of the wave.

Chaque volume est composé de deux parties, la première appelée cylindre, la seconde appelée piston et qui se déplace à l'intérieur du cylindre - Le piston est soumis à une double pression - une externe qui provient de la hauteur de l'eau, l'autre interne qui lui est opposée
Fig.l.Each volume is made up of two parts, the first called cylinder, the second called piston and which moves inside the cylinder - The piston is subjected to a double pressure - an external one which comes from the height of the water, l other internal opponent
Fig.l.

La pression interne est assurée mécaniquement au moyen d'un ressort, d'un fluide sous pression ou d'un poids. Elle est inférieure à la pression externe maximum et supérieure à la pression externe minimum
Selon la hauteur de l'eau à la verticale ou piston, la pression externe poussera le piston, sommet de la vague, et puis le piston sera ramené à sa position creux de la vague.The internal pressure is ensured mechanically by means of a spring, a pressurized fluid or a weight. It is less than the maximum external pressure and greater than the minimum external pressure
Depending on the height of the vertical water or piston, the external pressure will push the piston, top of the wave, and then the piston will be brought back to its hollow position of the wave.

En fonction des caractéristiques générales de la mer, marées par exemple, le mouvement de va-et-vient du piston est assuré au moyen de deux pressions externes - Dans ce cas, deux pistons sont opposés, distants l'un de l'autre et reliés entre eux - L'un est soumis à la pression maximum, sommet de la vague, l'autre à la pression minimum creux de la vague Fig.2. Depending on the general characteristics of the sea, tides for example, the reciprocating movement of the piston is ensured by means of two external pressures - In this case, two pistons are opposite, distant from each other and interconnected - One is subjected to the maximum pressure, top of the wave, the other to the minimum hollow pressure of the wave Fig. 2.

Les mouvements de va-et-vient du piston sont transmis par vérins ou mécanique à des générateurs d'énergie électrique. The reciprocating movements of the piston are transmitted by cylinders or mechanically to electrical energy generators.

Plusieurs volumes sont groupés pour former un dispositif d'ensemble - qui est immergé et fixé par tous moyens appropriés, ancrage ou poids. Several volumes are grouped together to form an overall device - which is submerged and fixed by any appropriate means, anchoring or weight.

Des cavités sont réparties à la périphérie du dispositif d'ensemble - Ces cavités sont réunies par deux, diamétralement opposées, par une conduite d'air - L'air est comprimé à la pression du creux de la vague Fig.3. Cavities are distributed around the periphery of the overall device - These cavities are joined by two, diametrically opposite, by an air line - The air is compressed at the pressure of the hollow of the wave Fig.3.

Quand une des deux cavités se trouve à la verticale du sommet de la vague, la pression est la plus forte et l'air est transféré dans la cavité opposée - Ce transfert provoque un déséquilibre > un mouvement de tangage et roulis qui est transmis à des générateurs.  When one of the two cavities is vertical to the top of the wave, the pressure is the strongest and the air is transferred into the opposite cavity - This transfer causes an imbalance> a movement of pitch and roll which is transmitted to generators.

Les cavités réparties à la périphérie du dispositif d'ensemble peuvent être remplacées par des volumes fixés aux deux extrémités d'une conduite d'air qui est articulée sur un axe - Le déséquilibre provoque sur cet axe une rotation partielle - Le mouvement de rotation est transmis à des générateurs d'énergie électrique Fig.4  The cavities distributed around the periphery of the assembly device can be replaced by volumes attached to the two ends of an air duct which is articulated on an axis - The imbalance causes a partial rotation on this axis - The rotational movement is transmitted to electric power generators Fig. 4
