Abstract

L'invention concerne un équipement pour produire de l'énergie électrique au moyen de la conversion de l'énergie des vagues de houle. L'invention vise à assurer la possibilité d'un changement rapide de masse et de déplacement de corps de travail (d'éléments flottants) de centrales houlomotrice afin d'assurer une transition plus efficace de l'énergie de la houle de fréquence (de période) et de force différentes vers un convertisseur d'énergie (une génératrice). L'élément flottant de centrale houlomotrice se présente comme un corps ayant du volume qui possède des cavités fermées non communiquant avec l'eau et assurant la flottabilité et des cavités ouvertes communiquant avec l'eau et situées en-dessous de la ligne de flottaison, qui forment dans leur partie supérieure des chambres à air communiquant avec l'atmosphère au moyen de deux conduites d'air dotées de soupapes électromagnétiques commandées d'admission et d'évacuation d'air.
