Abstract

L'invention concerne un appareil de production d'énergie houlomotrice à énergie cinétique. Ledit appareil comprend une base, un dispositif de conversion d'énergie houlomotrice constitué d'un canal d'eau (16) et d'une turbine à impulsions (1), un ensemble générateur constitué d'un générateur (2), d'une boîte de vitesses (3) et d'un premier volant inertiel (11), et un ensemble volant inertiel constitué d'un second volant inertiel (6) et d'un embrayage (9). Le dispositif de conversion d'énergie houlomotrice est relié à l'ensemble générateur au moyen d'un engrenage à plusieurs étages unidirectionnel et d'une chaîne (12); l'ensemble volant inertiel est relié à l'ensemble générateur au moyen de l'embrayage (9); et un siège de support pour la turbine à impulsions (1) est monté avec un élément de réglage de hauteur. Dans l'appareil, l'énergie cinétique d'une vague est complètement absorbée à l'aide d'une large aube de turbine en forme de crochet; la vitesse de rotation des volants peut être réglée et la rotation inverse est empêchée à l'aide de l'engrenage à étages multiples unidirectionnel, ce qui permet de mieux contrôler la vitesse de rotation des volants. L'ensemble volant inertiel est introduit de telle sorte que la vitesse de rotation des volants inertiels soit plus stable, et que l'énergie cinétique soit sortie, ce qui améliore ainsi le rendement de collecte de l'énergie des vagues.
