Abstract

L'invention concerne la production d'énergie électrique et notamment les centrales houlomotrices et marémotrices. Une installation de production d'énergie houlomotrice et marémotrice comprend un ponton flottant sur lequel est montée une roue de transmission ainsi qu'un cylindre vertical disposé sous l'eau, présentant une flottabilité positive et relié à une ancre par un lien souple posé sur le fond; un piston disposé à l'intérieur du cylindre et doté de la capacité de déplacement aller-retour sous l'effet de son propre poids, d'un ressort ou de tout autre mécanisme de retour; il peut se déplacer vers le haut sous l'effet de déplacement du ponton flottant, ce qui assure l'aspiration et l'évacuation du milieu de travail flottant depuis le cylindre et sont acheminement vers le générateur électrique ou sur terre ferme. Un lien souple passe par la roue de transmission du ponton flottant qui est relié par une extrémité au cylindre et par l'autre extrémité à la bielle du piston. L'installation de production d'énergie houlomotrice et marémotrice permet d'assure un rendement plus élevée grâce à l'augmentation de l'amplitude des oscillations du piston.
