Abstract

The assembly (200) has a floating structure comprising an inclined entry ramp (10). A set of wave sensors (40) is evenly distributed on the floating structure for capturing the force of input fluid wave. A set of transverse elements (50) is arranged to cooperate on either side of the floating structure by a cable sleeve (80) that is provided with a pair of notched wheels (62) on each end. The structure is fastened on both lateral sides with floats (105). The structure is fastened to an anchor (120) fixedly located at the bottom of water via a flexible stowing cable (110).

Description

Domaine technique L'objet de la présente invention a trait au domaine des installations énergétiques ; plus précisément, dans le domaine des installations houlomotrices adaptées pour exploiter la force cinétique des vagues. Etat de la technique Il existe 4 principaux types de dispositifs pour récupérer l'énergie des vagues : - - - - des bouées sous-marines en mouvement (colonnes d'eau oscillantes immergées), qui montent, descendent et tanguent au gré des vagues. Ancrées sur le fond, leur mouvement actionne un piston, aspire de l'eau de mer dans une turbine ou comprime de l'air ou de l'huile qui va faire tourner un moteur ; des colonnes d'eau oscillantes côtières : en fin de course, les vagues entrent dans un caisson où elles compriment l'air emprisonné. Cet air comprimé fait tourner une turbine des débordements de chenal : les vagues s'engouffrent dans un chenal qui se rétrécit de plus en plus. Elles enflent et débordent par-dessus la digue d'un réservoir qui se remplit peu à peu. L'eau du réservoir revient à la mer en passant par une turbine qu'elle fait tourner. Le réservoir peut se trouver sur la côte mais il existe aussi un projet de système de ce type flottant (qu'on appelle une plateforme à déferlement) des caissons flottants reliés entre eux par des charnières articulées. Les vagues déplacent les caissons dans tous les sens. On récupère de l'énergie au niveau des articulations mobiles entre les caissons, grâce à des pistons actionnant des pompes à huile sous pression. Résumé de l'objet de la présente invention L'objet de la présente invention est d'apporter une solution efficace, fiable et peu couteuse pour transformer l'énergie cinétique de la vague en énergie électrique. Et ce par un nouveau système couple mécanique de captation / transmission, qui transforme directement la force linéaire de la vague déferlante, en couple sur un arbre équipé d'un système de production d'énergie électrique Brèves description des figures: Les figures 1 à 2 annexées illustrent un exemple de réalisation dépourvu de tout caractère limitatif et sur lesquelles ; - la figure 1 représente de façon schématique une vue de face et de dessus du dispositif et détaille ses caractéristiques principales. - la figure 2 représente de façon schématique une vue de coté du dispositif40 Description détaillée d'un exemple de réalisation de la présente invention - le dispositif conforme à un exemple de réalisation avantageuse de la présente invention va maintenant être décrit dans ce qui suit en faisant référence conjointement aux figures 1 et 2.

STATE OF THE ART There are 4 main types of devices for recovering wave energy: - - - - underwater buoys in motion (submerged oscillating water columns), which rise, descend and pitch with the waves. Anchored on the bottom, their movement actuates a piston, draws seawater in a turbine or compresses air or oil that will turn an engine; Oscillating coastal water columns: at the end of the race, the waves enter a caisson where they compress the trapped air. This compressed air turns a turbine out of channel overflows: the waves rush into a channel that narrows more and more. They swell and overflow over the dike of a tank that fills up little by little. The water in the tank returns to the sea through a turbine that rotates. The tank may be on the coast but there is also a project of a system of this type floating (which is called a floating platform) floating boxes interconnected by articulated hinges. The waves move the boxes in all directions. Energy is recovered at the moving joints between the caissons by means of pistons operating pressurized oil pumps. SUMMARY OF THE OBJECT OF THE PRESENT INVENTION The object of the present invention is to provide an effective, reliable and inexpensive solution for transforming the kinetic energy of the wave into electrical energy. And this by a new mechanical torque capture / transmission system, which directly transforms the linear force of the breaking wave, in torque on a tree equipped with a power generation system Brief description of figures: Figures 1 to 2 annexed illustrate an example of embodiment devoid of any limiting character and on which; - Figure 1 schematically shows a front view and top of the device and details its main features.
