Abstract

La présente invention prévoit un procédé de prélèvement de l'énergie des vagues frappant les rives ou des plateformes artificielles/plateformes naturelles. Ce procédé utilise l'énergie cinétique et potentielle des vagues pour générer de l'électricité. Le mouvement alternatif des vagues est utilisé dans ce procédé pour générer de l'électricité. La gravité et le gradient du bassin sont aussi utilisés pour constituer une partie du mouvement et générer de l'électricité. Le mouvement alternatif de vague possédant une énergie cinétique et potentielle est utilisé dans la production d'un mouvement alternatif (mouvement linéaire) dans un champ magnétique dans l'appareil/machine (dispositif électromécanique) ayant pour conséquence le développement d'électricité. Ces appareils autonomes ou en série/groupe produiront ensemble de l'électricité. Dans le cas présent, l'oscillation ou le mouvement alternatif et l'énergie cinétique ou potentielle des vagues sont utilisés comme source. L'énergie des vagues est prélevée de manière unique (expliquée ci-dessous avec des illustrations). L'énergie électrique est créée par le mouvement alternatif oscillant d'un piston magnétique. Dans le cas présent, deux appareils pouvant être utilisés sont montrés ci-dessous et, dans les deux, l'énergie des vagues touchant la rive a été prélevée de la même manière mais avec quelques modifications. Tous les deux créent un mouvement linéaire dans le champ magnétique dans l'unité de conversion d'énergie, qui est en fait lancé par le mouvement alternatif des vagues et également par la gravité et le gradient du bassin ou en étant chargé par ressort ou à cause du poids de la partie génératrice. Dans cette illustration de l'appareil, il y a une plaque qui est exposée aux vagues. Cette plaque est en mesure de produire un mouvement alternatif. La plaque est reliée à un piston ou arbre magnétique à travers une bielle ou tige de raccordement. Les bobines se trouvent autour du piston qui développera du courant s'il y a une perturbation dans le flux. Là, à l'extrémité, se trouve un ressort qui a tendance à amener le piston vers un emplacement particulier. Il y a une construction artificielle qui divise la plaque et l'unité de conversion d'énergie et, par ceci, seul la tige de raccordement ou la bielle peut se déplacer. Le dessin de l'appareil/machine montre que la vague frappera les plaques. Ceci créera un mouvement linéaire dans les plaques. Par exemple, les plaques se déplaceront vers la rive ou plateforme étant donné que cette plaque est fixée avec une tige ou une bielle, qui à son tour est fixée à un arbre (ou un piston magnétique). Ceci provoquera un mouvement dans le piston ou arbre. L'arbre/piston sera magnétique et ceci coupera le flux et générera du courant. L'arbre, enfin, pourra être chargé avec un ressort qui ramènera la plaque dans la situation dans laquelle elle sera à nouveau frappée par la vague afin de recommencer encore le mouvement et créer un déplacement linéaire dans l'arbre ou piston pour générer du courant.
