Title (EN) WAVE ENERGY HARVESTER WITH THREE DEGREES OF FREEDOM
(FR) RÉCUPÉRATEUR D'ÉNERGIE HOULOMOTRICE À TROIS DEGRÉS DE LIBERTÉ
Abstract:
(EN) Irregular motion of waves creates a challenge to obtain energy efficiently. Heave type devices have been found to have high efficiencies, but they are limited to capturing energy along one or two directions of freedom. A new system and method for obtaining energy from the heaving motion of the waves is presented. It consists of base and heave structures connected through arm devices comprising three degrees of freedom, said arms powered by the motion of the heave structure in the fluid. These arm devices allow capture of wave energy by mechanical, hydraulic, or pneumatic systems.
(FR) Selon l'invention, un mouvement irrégulier d'ondes pose un défi à l'obtention efficace d'énergie. L'on a découvert que des dispositifs de type pilonnement offrent des rendements élevés, mais sont limités à la capture d'énergie dans une ou deux directions de liberté. On décrit un nouveau système et un nouveau procédé d'obtention d'énergie à partir du mouvement de pilonnement des vagues. Le système est constitué de structures de base et de pilonnement reliées par des dispositifs bras présentant trois degrés de liberté, lesdits à bras étant alimentés par le mouvement de la structure de pilonnement dans le fluide. Ces dispositifs à bras assurent la capture de l'énergie houlomotrice par des systèmes mécaniques, hydrauliques ou pneumatiques.
