Description

-1 - L'invention présentée ici concerne un dispositif permettant-1 - The invention presented here concerns a device allowing

d'exploiter d'énergie des vagues et de la houle. Du fait de son abondance, de sa régularité et de sa relative prévisibilité, l'énergie contenue dans les vagues présente certains avantages sur les autres énergies telles que solaire et éolienne. Cependant la non linéarité du mouvement de l'eau, le caractère corrosif de l'eau de mer ainsi que les conditions difficiles régnant dans l'environnement marin ont jusqu'à présent empêché d'apporter une solution économiquement viable à son exploitation. Le dispositif présenté ici se propose de répondre à ces défis. Il reprend certains des éléments contenus dans dans la demande de brevet 0404371 présentée par le même inventeur. Les différences avec ladite invention sont énoncées plus bas.  to harness energy from waves and waves. Due to its abundance, regularity and relative predictability, the energy contained in waves has certain advantages over other energies such as solar and wind. However, the non-linearity of water movement, the corrosive nature of seawater and the harsh conditions prevailing in the marine environment have so far prevented an economically viable solution to its exploitation. The device presented here proposes to answer these challenges. It contains some of the elements contained in the patent application 0404371 presented by the same inventor. The differences with said invention are set out below.

La présente invention se compose : - d'une structure flottante (1) supportant un minimum de trois organes rotatifs (2) tels que poulies ; -d'un minimum de trois organes d'ancrage (3) disposés sur 25 le fond marin ; - d'un ou de plusieurs organes de tension (4) ; - d'un minimum de trois organes de transmission flexibles (5) tels que câbles, courroies ou chaînes, - connectés à 30 une extrémité auxdits organes d'ancrage, exerçant une pression sur les organes rotatifs 2) et reliés à l'autre extrémité à l'organe ou aux organes de tension (4) ; - d'un ou de plusieurs appareils de transformation (6) tels 35 qu'alternateurs connectés aux organes rotatifs (2) ; - d'un ou de plusieurs agents conducteurs (7) tels que câbles électriques ou tuyaux, reliant la structure (1) à une unité de transformation ou de distribution située sur -2 - le rivage, ou bien à un second dispositif du même type. Les organes de tension peuvent être constitués d'un ou de plusieurs contrepoids immergés, de ressorts, de tendeurs ancrés sur le fond marin, de dispositifs pneumatiques, hydrauliques, oléopneumatiques ou de tous autres dispositifs permettant d'exercer une tension appropriée sur les organes de transmission (5). Les dessins annexés illustrent l'invention : La figure 1 représente une coupe de l'ensemble du dispositif de l'invention, un organe de tension unique étant placé au centre du dispositif. La figure 2 représente une vue de dessus de la partie 15 flottante de ce même dispositif. La figure 3 représente une coupe de l'ensemble du dispositif de l'invention avec une configuration différente, plusieurs organes de tension étant placés aux 20 extrémités extérieures des organes de transmission. Le dispositif de l'invention fonctionne de la façon suivante : les mouvements du liquide à la surface provoquent le déplacement vertical et horizontal de la 25 structure flottante (1). Le ou les organes de tension (4) maintiennent les organes de transmission (5) tendus, de sorte que tout mouvement de la plateforme est retransmis aux organes rotatifs (2) et converti en mouvement rotatif 30 bidirectionnel, permettant ainsi l'exploitation de l'énergie produite par ces mouvements. Les organes de tension (4), les organes de transmission (5) et les organes d'ancrage (3) ramènent la plateforme (1) à sa position 35 initiale après chaque déplacement. Le mouvement rotatif ainsi obtenu peut servir à produire du courant électrique sur la structure flottante même au moyen d'un ou de plusieurs appareils de transformation (6) connectés à un ou à plusieurs desdits -3 - organes rotatifs (2) ; le courant ainsi obtenu peut être transporté sur le rivage à l'aide des agents conducteurs (7), en l'occurrence des câbles électriques, pour être distribué sur le réseau électrique.  The present invention consists of: - a floating structure (1) supporting a minimum of three rotary members (2) such as pulleys; a minimum of three anchoring members (3) arranged on the sea floor; one or more tensioning members (4); a minimum of three flexible transmission members (5) such as cables, belts or chains, connected at one end to said anchoring members, exerting pressure on the rotary members 2) and connected to the other end the tension member or members (4); one or more transformation apparatuses (6) such as alternators connected to the rotating members (2); one or more conductive agents (7) such as electric cables or pipes, connecting the structure (1) to a processing or distribution unit located on the shore, or to a second device of the same type . The tensioning members may consist of one or more submerged counterweights, springs, anchors anchored to the seabed, pneumatic, hydraulic, oleopneumatic devices or any other devices for exerting an appropriate tension on the transmission (5). The accompanying drawings illustrate the invention: FIG. 1 represents a section of the entire device of the invention, a single voltage member being placed in the center of the device. FIG. 2 represents a view from above of the floating part of this same device. FIG. 3 represents a section of the entire device of the invention with a different configuration, with several tensioning members being placed at the outer ends of the transmission members. The device of the invention operates in the following way: the movements of the liquid at the surface cause the vertical and horizontal displacement of the floating structure (1). The tensioning member (s) (4) hold the transmission members (5) taut so that any movement of the platform is transmitted back to the rotary members (2) and converted into bidirectional rotational movement, thus allowing the operation of the energy produced by these movements. The tensioning members (4), the transmission members (5) and the anchoring members (3) return the platform (1) to its initial position after each movement. The rotary motion thus obtained can be used to produce electric current on the floating structure even by means of one or more transformers (6) connected to one or more of said rotating members (2); the current thus obtained can be transported to the shore by means of conductive agents (7), in this case electric cables, to be distributed over the electrical network.

Le mouvement rotatif peut également être utilisé pour comprimer de l'air ou de l'eau, qui sont acheminés sur le rivage à l'aide des agents conducteurs (7), en l'occurrence des tuyaux ou conduits. Le liquide ou gaz comprimé peut alors actionner un ou plusieurs appareils de transformation situé(s) sur le rivage. Dans le cas d'eau sous pression, le procédé peut servir à des opérations de pompage ou bien de désalinisation.  The rotary movement can also be used to compress air or water, which is conveyed to the shore by means of the conducting agents (7), in this case pipes or ducts. The liquid or compressed gas can then operate one or more transformers located on the shore. In the case of pressurized water, the process can be used for pumping or desalting operations.

La présente invention diffère substantiellement de la demande de brevet 0404371 présentée par le même inventeur en ce que, notamment: 1) en lieu et place du ballast se trouvent des organes de 20 tension pouvant être constitués de tendeurs, ressorts, pompes, pistons, etc. 2) la tension exercée par ce ou ces organes de tension peut être produite depuis le centre du dispositif comme depuis 25 les extrémités extérieures des organes de transmission ; 3) en lieu et place de la plateforme se trouve une structure composée le cas échéant de plusieurs plateformes permettant au dispositif d'exploiter une plus large variété 30 de configurations de vagues ; 4) la transformation du mouvement rotatif peut être opérée depuis seulement un, voire deux des organes de rotation ; 5) la disposition différente des organes de transmission 35 autorise des configurations d'installation différentes ; 6) l'invention permet de diversifier les configurations dans le processus de transformation de l'énergie.  The present invention differs substantially from the patent application 0404371 presented by the same inventor in that, in particular: 1) instead of the ballast there are tensioning members that can consist of tensioners, springs, pumps, pistons, etc. . 2) the tension exerted by this or these tension members can be produced from the center of the device as from the outer ends of the transmission members; 3) in place of the platform is a structure composed of several platforms if necessary allowing the device to exploit a wider variety of wave configurations; 4) the transformation of the rotary movement can be operated from only one or two of the rotating members; 5) the different arrangement of the transmission members 35 allows different installation configurations; 6) the invention makes it possible to diversify the configurations in the process of transforming the energy.
