Abstract

La présente invention concerne un convertisseur d'énergie houlomotrice permettant d'augmenter la sécurité et la durée de vie du système en nivelant la variation du taux de conversion d'énergie d'une vague de surface dans un cycle et la tension du câble pour en supprimer les valeurs maximales. Le convertisseur d'énergie houlomotrice comprend un moyen de stockage de l'énergie disposant d'une poulie de tension (9) et d'un ressort de soutien (10). Un flotteur (4) flottant à la surface de l'eau est déplacé verticalement par la variation du niveau d'eau par vague. Lorsque le flotteur (4) est largement abaissé par une vaque d'eau de surface forte, la tension ff est augmentée. Dans ce cas, la poulie de tension (9) installée entre une poulie de commande (6) et une poulie fixe (7) rétracte le ressort de soutien (10) vers le bas pour stocker une énergie en fonction de la force de compression (F) du ressort de soutien (10). L'énergie est libérée lorsque la surface de l'eau s'élève, au moment où une tension de fil effective est considérablement réduite, pour la transformer en énergie de mouvement rotatif. L'énergie convertie est amenée à une génératrice (1) pour générer de l'électricité.
