Description

La présente invention concerne un convertisseur d'énergie de la surface et celle sous-jacente, des mers et océans en énergie électrique. L'énergie des mers et océans. est la plus répendue, la plus puissante et renouvelée, mais la plus difficile à convertir en raison des flux et reflux très lents, avec d'importants temps morts surtout dans l'utilisation de la marée comme force motrice. L'invention ci-après décrite se distingue par l'utilisation du mouvement des vagues mais surtout de l'énorme puissance sous-jacente 10 de la masse d'eau en mouvement continuel. Pour obtenir ce résultat de conversion d'énergies, selon l'invention, il est utilisé des éléments flotants, en partie immergés, reliés entre-eux, mais indépendants (1) Fig.A,disposés en chaine, dont les mouvements entre-eux et sur eux-mêmes causés par les différents 15 mouvements et poussées de l'eau, provoquent la rotation pratiquement continue-du. rotor des générateurs électriques •à l'aide d'éléments mécaniques. La Fig.B sembolise le mouvement de l'eau ( de A à B) avecmouvements des flotteurs.The present invention relates to a power converter of the surface and that underlying, seas and oceans in electrical energy. The energy of the seas and oceans. is the most widespread, the most powerful and renewed, but the most difficult to convert because of very slow ebb and flow, with significant downtime especially in the use of the tide as a driving force. The invention described here is distinguished by the use of the wave movement but especially the enormous power underlying the water mass in continuous motion. To obtain this result of energy conversion, according to the invention, it is used floating elements, partially immersed, connected to each other, but independent (1) Fig.A, arranged in a chain, whose movements between them and on themselves caused by the different movements and thrusts of the water, cause practically continuous rotation of the. rotor of electric generators • using mechanical elements. Fig.B sembolises the movement of water (from A to B) with movements of the floats.

20 L'action de conversion se fait sans utilisation de fluide intermédiaire, pompes, réservoirs, compresseurs, Turbines '6u autres Afin d'utiliser aumaximum les mouvements de-l'eau, les flotteurs ont leur base en partie immergée et lestée, ce qui confère à la chaine un effet stabilisateur et amortisseur indispensable. La distance rapprochée entre les flotteurs sera adaptée selon les particularités de la z8ne d'utilisation. La chaine de flotteurs peut être de nombre, longueur, importance, selon la puissance recherchée. Des chaines peuvent être juxtaposées en parallèle peur obtenir 30 de très grandes puissances. Vu leur fonction de surface active, les flotteurs n'ont pas de caractéristiques définies etpeuvent être de formes, dimensions, volume, très divers. L'intérieur de chaque flotteur renferme un générateur électrique, 35 lequel peut éventuellemnt être fixé à l'extérieur. Ne nécessitant pas d'infrastructure, la chaine de flotteurs est reliée au rivage ou au fond marin par tous moyens usuels. La réalisation de l'invention, dont la descriptionsuivante n'est pas limitative, peut recevoir des variantes ou des modifications 4.0 constructives que la mise en oeuvre ou l'usage révéleraient nécessaires mais sans s'écarter de l'esprit et du cadre de l'invention.The conversion action is carried out without the use of intermediate fluid, pumps, tanks, compressors, turbines, etc. In order to use the movements of the water at the maximum, the floats have their bases partly submerged and ballast, which gives the chain an essential stabilizing and damping effect. The close distance between the floats will be adapted according to the particularities of the use zone. The chain of floats can be of number, length, importance, according to the desired power. Channels can be juxtaposed in parallel to obtain very large powers. Due to their active surface function, floats have no defined characteristics and can be of various shapes, sizes, volumes and volumes. The interior of each float contains an electric generator, which may possibly be attached to the outside. Not requiring infrastructure, the chain of floats is connected to the shore or the seabed by any usual means. The embodiment of the invention, the description of which is not limiting, may receive constructive variations or modifications 4.0 that the implementation or use would reveal necessary but without departing from the spirit and context of the invention. 'invention.

25 Exemple de réalisation selon l'invention : Les flotteurs sont reliée entre-eux par des barres 3 Fig.1 situées de chaque côté. Une extrémité de chaque barre est fixée à-un flotteur, l'autre 5 extrémité étant fixée à l'axe 17 Fig.0 de rotation de commande du générateur électrique à l'aide d'organes intermédiaires appropriés. Pour la transformation des mouvements des (1) en un mouvement rotatif des rotors des génrateurs électriques (2), il est utilisé un système de leviers (16) dont le rôle est de ptransmettre et 10 d'utiliser les deux sens des oscillations des flotteurs Fig.E ce qui permet un:.rendement maximum-. Bras alternatifs 6 et 7 , leviers 16 . Les impulsions des leviers (16) sont communiquées à une roue à jante plat (5) ou latéralement à un disque de fonction analogue, par une disposition en roue libre à sens unique de rotation Fig.D, 15 5, 6, 7 Le sens unique de rotation est obtenu par cliquet ,-mais-.de préférence pou-r raisons de simplicité et silence, par des coins de de blocage ronds (4) Fig.D, placés dans des logements .f ig ~6;7 avec ressorts, dors les parties des pièces de commande (6 et 7) Fig.Embodiment of the invention: The floats are connected to each other by bars 3 Fig.1 located on each side. One end of each bar is attached to a float, the other end being fixed to the axis 17 of control rotation of the electric generator by means of appropriate intermediate members. For the transformation of the movements of (1) into a rotational movement of the rotors of the electric generators (2), a system of levers (16) is used, the function of which is to transmit and use the two directions of the oscillations of the floats. Fig.E which allows a:. Maximum efficiency. Alternative arms 6 and 7, levers 16. The pulses of the levers (16) are communicated to a flat rim wheel (5) or laterally to a similar function disc by a one-way free-wheeling arrangement. Fig.D, 5, 6, 7 The meaning Unique rotation is obtained by ratchet, but preferably for reasons of simplicity and silence, by round locking wedges (4) Fig.D, placed in housings .fig ~ 6; 7 with springs , in the parts of the control parts (6 and 7) Fig.

20 D et E . La pièce de blocage (4) peut se présentersous forme de coin, avec un effet identique. L'utilisation des deux sens, inveres, des impulsions à chaque cycle des mouvements divers, permet une rotation continue des rotors sans a-coups et de doubler la conversion d'énergies - 25 L'action de rotationest soit directe ou par l'intermédiaire d'engrenages multiplicateurs. Fig. C & D 13, 14, 15 . En raison des faibles fréquences des mouvements de l'eau , afin d'obtenir unevitesse circonférentielle optimum du rotor des générateurs, ceux-ci pourront être avantageusement réalisés 30 sous une nouvelle forme, c'est à dire les inducteurs sous forme d'anneau séparé , distant de l'arbre central Fig.0 , moyeu 12 tournant sur l'arbre central 17 , Ces inducteurs étant du plus grand diamètre possible. permis par le flotteur. Le rotor comporte les éléments inducteurs magnétiques permanents 35 multiples 11, le bobinage induit 12 réalisé en nappe mince. - L'équipement électrique est usuel: appareillage, accessoires, protections, cablage;étanche, onduleur . - Un petit compresseur à membrane et soupape de pression maximum permettent d'éviter d'éventuelles infiltrations par les joints 40 d'étanchéité. Intérêts de l'invention: L'invention vise à supprimer ou surmonter les particularités restrictives suivantes: L'exploitation' de l'énergie marine reste inexploitée, faute 45 de moyens adéquats à ses diverses particularités, comme les très lents mouvements de la masse,. temps morts importants des marées. L'échec est aussi en raison des coûts exorbitants des moyens et installations proposés, des très rares possibilités d'implantations, généralement inextensibles, temps morts sans -production ,- 50 gênes diverses, rendements et productions dérisoires, trop grande complication, indigence ou utopie des moyens proposés. D and E. The locking piece (4) can be in the shape of a wedge, with an identical effect. The use of both directions, inverts, pulses with each cycle of various movements, allows a continuous rotation of the rotors without jolts and to double the conversion of energies - 25 The action of rotationis either direct or via gearing multipliers. Fig. C & D 13, 14, 15. Because of the low frequencies of the movements of the water, in order to obtain an optimum circumferential speed of the rotor of the generators, these may advantageously be produced in a new form, ie the inductors in the form of a separate ring. , remote from the central shaft Fig.0, hub 12 rotating on the central shaft 17, these inductors being the largest possible diameter. allowed by the float. The rotor comprises the multiple permanent magnetic inductor elements 11, the induced coil 12 made of thin sheet. - Electrical equipment is usual: switchgear, accessories, protections, wiring, waterproof, inverter. - A small diaphragm compressor and maximum pressure valve to prevent possible infiltration by the seals 40. OBJECTS OF THE INVENTION: The invention aims at eliminating or overcoming the following restrictive features: The exploitation of marine energy remains untapped due to the lack of means adequate to its various peculiarities, such as the very slow movements of the mass, . significant dead time of the tides. Failure is also due to the exorbitant costs of the means and facilities offered, the very rare possibilities of implantation, generally inextensible, dead time without production, - 50 different genes, yields and derisory productions, too much complication, indigence or utopia proposed means.
