Title (EN) SYSTEM FOR CONVERSION OF WAVE ENERGY
(FR) SYSTEME SERVANT A CONVERTIR L'ENERGIE DES VAGUES
Abstract:
(EN) A system for conversion of wave energy in a body of water having a floor, comprising a stationary element (9) rigidly mounted to the floor of the body of water, buoyancy means (13), coupling means for hingedly connecting the buoyancy means to the stationary element wherein the buoyancy means is pivotal in a vertical plane about a central axis in the stationary element (9), at least one piston means (49) for compressing and drawing hydraulic fluid when the piston means is contracted or extended, correspondingly, the piston means being hinged at one end to the stationary element or the floor and hinged at its other end to the buoyancy means or the coupling means, a hydraulic motor (53) mechanically coupled to an electric generator or to any other applicable device, and a piping system (57) coupling the hydraulic fluid in the piston means to the hydraulic motor.
(FR) Système servant à convertir l'énergie des vagues dans une masse d'eau possédant un fond, ledit système étant composé d'un élément fixe (9) monté rigide sur le fond de la masse d'eau, de moyens de flottaison (13), de moyens d'accouplement servant à accoupler de façon articulée les moyens de flottaison à l'élément fixe, lesdits moyens de flottaison étant pivotants dans un plan vertical autour d'un axe central de l'élément fixe (9), d'au moins un piston (49) servant à comprimer et à aspirer le liquide hydraulique, quand ce piston est en position respective de retrait ou d'extension, ledit piston étant articulé par une extrémité à l'élément fixe ou au fond et par l'autre extrémité aux moyens de flottaison ou aux moyens d'accouplement, d'un moteur hydraulique (53) relié mécaniquement à une génératrice électrique ou à tout autre dispositif approprié, ainsi que d'un système de conduits (57) mettant en communication le liquide hydraulique dans le piston avec le moteur hydraulique.
