Abstract

L'invention concerne un dispositif servant à convertir l'énergie résultant d'un mouvement oscillant en énergie électrique, en particulier d'un mouvement oscillant induit par des vagues, qui comprend un corps de base (1) configuré de sorte à effectuer un mouvement oscillant sous l'effet de la force oscillante extérieure exercée sur le corps de base (1), un mécanisme de conversion, configuré de sorte à convertir le mouvement oscillant du corps de base (1) en un mouvement rotatif d'un élément de conversion autour d'un axe de rotation. L'axe principal du mécanisme de conversion est conçu pour rester sensiblement vertical pendant le mouvement oscillant, indépendamment de l'état d'inclinaison du corps de base (1). Le dispositif comporte également une génératrice configurée de sorte à convertir en énergie électrique l'énergie résultant du mouvement rotatif de l'élément de conversion autour de l'axe longitudinal. L'invention concerne par ailleurs un système comportant plusieurs dispositifs pour convertir l'énergie résultant d'un mouvement oscillant en énergie électrique.
