Abstract

La présente invention concerne un équipement de génération d'énergie à liaison de bouées multiples comportant un système de bouées (1), un système de bielle (2) et un système de conversion de couple (3). Le système de bouées (1) est une bouée rectangulaire (101) avec un angle circulaire. Des joints universels (110) et des tiges de dispositif hydraulique (120) sont installés sur la face latérale du système de bouées. Le système de conversion de couple (3) est installé à l'intérieur ou au-dessus du système de bouées. Deux bouées adjacentes (101) sont connectées à travers une bielle par le joint de universel (110). La bouée se déplace verticalement le long des vagues pour entraîner les bielles pour la génération d'un couple et le système de conversion de couple (3) convertit le couple en énergie électrique. L'équipement de génération d'énergie à liaison de bouées multiples est peu coûteux et possède un taux élevé de conversion d'énergie et une bonne stabilité intégrale, avec une bonne capacité de résistance aux tempêtes.
