Abstract

La présente invention concerne un convertisseur d'énergie des vagues. Le convertisseur d'énergie des vagues de la présente invention comprend un corps flottant (100), qui est déplacé verticalement par les vagues, et une unité d'actionnement. L'unité d'actionnement comprend : une unité rotative combinée (210) qui est couplée au corps flottant et au sol et qui comprend un rotateur mobile (212), ou est formée par une combinaison d'un rotateur mobile et d'un rotateur fixe (214); un élément linéaire (220), qui est raccordé à l'unité rotative combinée et qui effectue un mouvement alternatif en fonction du mouvement du corps flottant; et un élément de maintien de tension qui maintient l'élément linéaire tendu. Le convertisseur d'énergie des vagues comprend également une unité de conversion qui convertit l'énergie de vagues en d'autres formes d'énergie. Par conséquent, au moyen de la présente invention, la distance sur laquelle l'élément linéaire est déplacé est augmentée de plusieurs fois par rapport la distance de déplacement d'un corps flottant, ce qui permet d'assurer une conversion d'énergie efficace.
