Le couvercle d'extrémité supérieure (1) et le couvercle d'extrémité inférieure (2) sont munis de trous d'arbre, un arbre de roue à eau (5) étant installé à l'intérieur des trous d'arbre, un disque à lames (12) étant connecté fixement à la partie centrale de l'arbre de roue à eau (5), la partie supérieure et la partie inférieure du disque à lames (12) étant connectées à des tiges de lames (13, 14), les tiges de lames (13, 14) étant connectées de manière mobile à des lames (131, 141) aptes à tourner autour des tiges de lames. La volute est munie d'une admission d'eau (7) et d'une sortie d'eau (8). Des plaques barrière d'eau (15) qui empêchent le passage de l'eau sont disposées entre l'admission d'eau (7) et la sortie d'eau (8). Les plaques barrière d'eau (15) sont disposées sur la chicane avant de volute (4), le couvercle d'extrémité supérieure (1) ou le couvercle d'extrémité inférieure (2). Un espace pour le passage des lames (131, 141), des tiges de lames (13, 14) et du disque à lames (12) est réalisé entre les plaques barrière d'eau (15) ou entre les plaques barrière d'eau (15) et le couvercle d'extrémité supérieure (1), et les plaques barrière d'eau (15) et le couvercle d'extrémité inférieure (2). L'écoulement d'eau depuis l'admission d'eau (7) jusqu'à la sortie d'eau (8) fait tourner l'arbre de roue à eau (5). Le dispositif de conversion de l'énergie des vagues selon l'invention a une structure simple, des coûts de fabrication bas et utilise complètement l'énergie naturelle des vagues pour ainsi générer de l'électricité de manière rentable à partir des vagues.
