Abstract

The generator has a number of floats (27) guided vertically and distributed round the periphery of the supporting platform (17). The height of the guides is matched to the swell in the location where the generator is installed. The floats drive a generator whose power is delivered to land through a cable (21). An inverter (22) passes the energy to the electricity network.

Description

La présente invention concerne la production d'énergie électrique, par laThe present invention relates to the production of electrical energy, by the

puissance de la houle et des vagues pendant la montée et descente de 17élément liquide.  wave and wave power during the rise and fall of the liquid element.

Divers utilisations de cette énergie la transforment soit en compression d?air ou de liquides en une rotation de sens approprié à la génératrice. Ici, I'eau élève les flotteurs selon le poids et 1'énergie captés. En descente, seul le poids permet la production correspondante. Cette production se fait par l'intermédiaire d'océanogénératrices, (vue de la tranche, fig I bis) constituées d'un rotor de huit poles bobinés sur un ensemble de  Various uses of this energy transform it either into compression of air or liquids in a rotation of direction appropriate to the generator. Here, the water raises the floats according to the weight and energy captured. On the descent, only the weight allows the corresponding production. This production is done through oceanogenerators, (view of the section, fig I bis) made up of a rotor of eight poles wound on a set of

toles empilées et collées (1), afin d'isoler les courants de Foucault.  stacked and glued sheets (1), to isolate the eddy currents.

Ces tôles, elles-mémes situées autour d'une poulie évidée pouvant étre faite de plastique (2),pour une meilleure réduction de poids inertiel entre 1'ase d'entramement (3) et les pièces des circuits magnétiques (4). Ces derniers ont la particularité d'étre bobinés de façon à ce que deux poles consécutifs soient Nord ou Sud, afin de minimiser les phénomènes d'hystérésis dans les circuits magnétiques des bobines induites venant de produire. La création du champs magnétique des inducteurs est du à un courant électrique dérivé de celui produit par la machine et injecté par le contact des balais (9) sur deux  These sheets, themselves located around a hollowed out pulley which can be made of plastic (2), for a better reduction of inertial weight between the mounting base (3) and the parts of the magnetic circuits (4). The latter have the particularity of being wound so that two consecutive poles are North or South, in order to minimize the hysteresis phenomena in the magnetic circuits of the coils induced just to produce. The creation of the magnetic fields of the inductors is due to an electric current derived from that produced by the machine and injected by the contact of the brushes (9) on two

bagues connectées aux circuits correspondants mis en parallèle (10).  rings connected to the corresponding circuits placed in parallel (10).

La partie statorique, également constituée d'un empilement de toles encollées, supporte les bobines productrices (5) générant un courant alternatif correspondant à la variation du champ magnétique. Il est d'autant plus brutal qu'il passe de zéro au maximum lors d'une rotation de 22.5 , quelque soit le sens de rotation donné en fonction  The stator part, also consisting of a stack of glued sheets, supports the producing coils (5) generating an alternating current corresponding to the variation of the magnetic field. It is all the more brutal that it goes from zero to maximum during a rotation of 22.5, whatever the direction of rotation given in function

de l'élévation des vagues.wave elevation.

Le courant alternatif est redressé par un pont de diodes (6) correspondant à chaque bobine, ce courant étant instable de par son origine. Les diodes boulonnées aux barres collectrices (7) sont reDroidies par les écrous radiateurs (8) grâce à la circulation ambiante générée par l'hélice en bout d'arbre (12). Cette ventilation passera aussi le long des bobines. 2 Le courant ainsi redressé est stabilisé par un condensateur (11) en dérivation sur  The alternating current is rectified by a diode bridge (6) corresponding to each coil, this current being unstable by its origin. The diodes bolted to the busbars (7) are cooled by the radiator nuts (8) thanks to the ambient circulation generated by the propeller at the end of the shaft (12). This ventilation will also pass along the coils. 2 The current thus rectified is stabilized by a capacitor (11) bypassing on

l'ensemble des bobines.all of the coils.

Les barres, diodes et portes balais sont fixés sur un support isolant coulé formant une couronne (13), positionné au sommet de la machine sous le capotage (14). Un  The bars, diodes and brush holders are fixed on a cast insulating support forming a crown (13), positioned at the top of the machine under the cover (14). A

second capot (15) se trouve en bas de l'ensemble étanche (16).  second cover (15) is located at the bottom of the sealed assembly (16).

Il est évident qu'une seule machine représente peu de production par rapport aux possibilités océanes. C'est pourquoi il est intéressant de grouper quatre machines par flotteur (27) qui, selon la houle, sont guidés le long de tubes (23) de longueur appropriée  It is obvious that a single machine represents little production compared to the ocean possibilities. This is why it is interesting to group four machines per float (27) which, depending on the swell, are guided along tubes (23) of appropriate length.

Cet ensemble en forme de tour océnogénératrice comporte en son sommet une plate forme (18), au centre de laquelle est suspendu la chambre (19) de réunion des câbles souples (20) formés de quatre conducteurs chacun. Chaque conducteur est relié à un ampèremètre puis à un sectionneur avec fusible, avant la liaison au câble de transport (21) constitué d'un seul brin, de section appropriée, relié sur la côte à un onduleur (22) au réseau. Le retour passe par la terre, via une liaison de chaque flotteur aux génératrices de base. Sur toute la longueur des tubes guides (23) diamétralement opposées se trouvent deux crémaillères (24) qui transmettent 1'énergie captée au pignon receveur, solidarisé des arbres terminés par des renvois d'angles enfermés dans des bo^tes à graisse étanches (25). Ces renvois d' angles ont aussi un rôle de multiplicateurs de vitesse de rotation,  This assembly in the form of an oxygen generator tower comprises at its top a platform (18), in the center of which is suspended the chamber (19) for meeting flexible cables (20) formed of four conductors each. Each conductor is connected to an ammeter and then to a disconnector with fuse, before connection to the transport cable (21) consisting of a single strand, of appropriate section, connected on the side to an inverter (22) to the network. The return goes through the earth, via a connection from each float to the base generators. Over the entire length of the diametrically opposed guide tubes (23) are two racks (24) which transmit the energy captured to the receiving pinion, integral with the shafts terminated by gearboxes enclosed in sealed grease boxes (25 ). These angle references also have the role of speed multipliers,

arrivant à chacune des quatre océanogénératrices.  arriving at each of the four oceanogenerators.

Le maintien face à face des engrenages est assuré par des patins (25) en téflon ou autre, fixés à l'intérieur des couronnes (27) formées par la fabrication des flotteurs, ceci  The face to face maintenance of the gears is ensured by pads (25) in teflon or other, fixed inside the crowns (27) formed by the manufacture of the floats, this

La tension possible de ces ensembles est à déterminer suivant  - 3 At the top of the floats there is a perfectly sealed cable guide outlet (28). In its vicinity (not shown) a hatch allows access to useful internal electrical connections. The possible tension of these assemblies is to be determined according to
