Abstract

L'invention concerne un appareil de production d'électricité au moyen de l'énergie houlomotrice. Une pluralité d'arbres rotatifs entraînés par l'énergie houlomotrice et mis en rotation par les mouvements ascendants et descendants de flotteurs sont disposés au niveau d'un arbre fixe fixé sur une structure en mer pour convertir l'énergie houlomotrice en énergie électrique, et de l'électricité est produite par la rotation d'un arbre rotatif d'une génératrice au moyen de la force de rotation de celui-ci. Une pluralité de flotteurs (70a, 70b, 70c, 70d) sont placés à flot sur la mer pour générer une flottabilité, une pluralité de barres de raccordement (75a, 75b, 75c, 75d) de flotteurs sont respectivement reliées à la pluralité de flotteurs (70a, 70b, 70c, 70d), et une pluralité d'arbres rotatifs entraînés par l'énergie houlomotrice (50a, 50b, 50c, 50d) sont mis en rotation par les mouvements ascendants et descendants de la pluralité de flotteurs. La rotation de la pluralité d'arbres rotatifs entraînés par l'énergie houlomotrice (50a, 50b, 50c, 50d) est transmise à un arbre rotatif (20) d'une génératrice par des unités de transmission de force de rotation avant et arrière (40, 45), la pluralité d'arbres rotatifs entraînés par l'énergie houlomotrice (50a, 50b, 50c, 50d) et l'arbre rotatif (20) de la génératrice sont soutenus par une paire de plaques de support gauche et droite (30a, 30b), et la paire de plaques de support (30, 30) est soutenue par l'arbre fixe (10) et l'arbre fixe (10) est fixé à la structure fixe de manière à former un module unitaire (100). La génératrice convertit les mouvements linéaires ascendants et descendants en mouvements rotatifs en fonction des vagues par la configuration d'au moins deux modules unitaires (100) en un ensemble (200), et peut être conçue de façon économique sans limitation de capacité d'installation et d'emplacement d'installation en augmentant et en réduisant facilement sa taille en fonction de l'augmentation et de la réduction du nombre d'ensembles. La génératrice de l'invention peut également accroître le rendement de conversion de l'énergie houlomotrice en énergie électrique par maximisation de la capacité de production dans le même volume.
