Abstract

The generator uses the power available in the waves on the sea in order to produce electricity for industrial purposes. The assembly includes two floats on either side of a rectangular housing. Inside the housing is divided vertically into three main sections, the central section housing a turbine and electrical generator. The two outer sections each have a series of inclined shelves, with their free ends close together in the middle of each section. There are a series of anti-return valves on the edges of the shelves, so that as the sections rock to an fro, water moves from one shelf to another. The water is gradually lifted up through the section in order to fall back down through the central turbine.

"FLOATING DEVICE TRANSFORMING THE CORD MOTION
DB LA HOULE NARINE IN INDUSTRIALLY USEABLE ENERGY
André RODRIGUEZ
Patent prls April 26, I979
Requested January 19, 1981
This addition is intended to supplement, in the terms below, the description and claims of the principle patent
The circulation of water in the device can also be done in a closed circuit, thus constantly reusing the same water load. The device is then presented in the following form: with reference to the drawings, FIG. 1 is a plan view of the entire device at sea, its anchors resting on the bottom.

La figure 2 est une vue suivant li de la figure 1. La figure 3 est une vue suivant CC de la figure 2. Deux flotteurs 1 et 2 sont relié par des volumes 3 et 4 contenant les guindeaux de mouillage et de correction d'orientation du dispositif, ainsi que les chambres de stockage des lignes de mouillage pendant les déplacements du dispositif flottant. Figure 2 is a view along li of Figure 1. Figure 3 is a view along CC of Figure 2. Two floats 1 and 2 are connected by volumes 3 and 4 containing the anchor and orientation correction windlasses of the device, as well as the storage rooms for the mooring lines during the movements of the floating device.

Dans le cadre flottant formé par les flotteurs 1 et 2 et les volumes de liaison 3 et 4, sont installés ae part et d'autre de l'aie de symétrie de l'ensemble, des compartiments tels que 5-6-7-8-9-IO-II-I2-13-14-I5-16, sans communication avec les flotteurs6
La figure 4 est une coupe de la figure 1 suivant 2,B, par les compartiments 7 et I4, qui montre la disposi-tion interne des compartiments.L'ensemble des compartiments 5-6-7-8-9-10-11-12-I3
I4-I5-I6 est relié au sommet par un plume réservoir I74 Tous les compartiments communiquent avec le réservoir 17 par des ouvertures, telle que 22, dotées de clapets antiretour, tel que 23, pour le compartiment 14. Dans le volume réservoir 17 sont disposée es cloisonnements perfores, tel que 24, destinés à limiter les mouvements oscillants de l'eau, sans pour autant gêner son écoulement vers la conduite 21 de la turbine hydraulique,
L'ensemble des compartiments 5-6-7-8-9-10-11-12-13-14-15-16 est relié à la base par un volume réservoir I8 qui communique avec chacun des compartiments. L'espace I9, compris entre le réservoir supérieur I7 et le réservoir inférieur 18, reçoit une turbine hydraulique classique 20 accouplée à une génératrice électrique, avec leurs appareils de contre et de régulation, ainsi que la centrale de conduite automatique du dispositif flottant.In the floating frame formed by the floats 1 and 2 and the connecting volumes 3 and 4, compartments such as 5-6-7-8 are installed on either side of the symmetry section. -9-IO-II-I2-13-14-I5-16, without communication with the floats6
Figure 4 is a section of Figure 1 along 2, B, by compartments 7 and I4, which shows the internal disposition of the compartments. All of the compartments 5-6-7-8-9-10-11 -12-I3
I4-I5-I6 is connected to the top by a reservoir feather I74 All the compartments communicate with the reservoir 17 by openings, such as 22, provided with non-return valves, such as 23, for the compartment 14. In the reservoir volume 17 are arranged in perforated partitions, such as 24, intended to limit the oscillating movements of the water, without interfering with its flow towards the pipe 21 of the hydraulic turbine,
All of the compartments 5-6-7-8-9-10-11-12-13-14-15-16 are connected to the base by a tank volume I8 which communicates with each of the compartments. The space I9, comprised between the upper tank I7 and the lower tank 18, receives a conventional hydraulic turbine 20 coupled to an electric generator, with their counter and regulation apparatus, as well as the automatic control unit of the floating device.

Une conduite 21 relie le réservoir supérieur 17 au réservoir inférieur I8 à travers la turbine 20. A pipe 21 connects the upper tank 17 to the lower tank I8 through the turbine 20.

Chacun des compartiments, tel que I4, est divisé sur toute sa hauteur en chambres superpose-es dont les plans inclinés, tels que 25-26-27-28, sont imbriqués de telle manière qu'ils forment une série continue de chambres communicantes de bas en haut grace à des clapets tels que 29-30-31-32. Les matelas d'air emprisonnés dans ces chambres par l'eau en oscillation sont évacués grâce à des orifices, tel que 33, dans des gaines telle que 34, débouchant sur des évents tel que 35. En variant les dimensions des orifices des évents, il est possible de ralentir et de limiter les mouvements des masses d'eau dans les chambres0
La mise en action à la mer du dispositif suppose un remplissage préalable avec la quantité d'eau nécessaire.Les oscillations imprimées par la houle au dispositif et par conséquent aux masses liquides qu'il contient, aboutissent, dans tous les compartiments, à l'élévation d'un certain volume d'eau qui progresse par gravité à travers les clapets et se déverse au sommet des compartiments dans le réservoir d'alimentation I7 de la turbine hydraulique 20. Ce volume circulant à travers la turbine hydraulique 20 tombe dans le réservoir 18. Le réservoir 18 alimente par gravité la première chambre de base de tous les compartimente telle que 36 pour le compartiment 7.La figure 5 représente une coupe suivant BB de la figure l par les compartiments 7 et I4 du dispositif en action à la mer quand le flotteur 2 est soulevé, la figure 6 quand le flotteur 1 est soulevé, au cours d'une oscillation.Each of the compartments, such as I4, is divided over its entire height into superimposed chambers whose inclined planes, such as 25-26-27-28, are nested in such a way that they form a continuous series of communicating chambers of bottom up thanks to valves such as 29-30-31-32. The air mattresses trapped in these chambers by the oscillating water are evacuated by means of orifices, such as 33, in sheaths such as 34, leading to vents such as 35. By varying the dimensions of the orifices of the vents, it is possible to slow down and limit the movements of the bodies of water in the rooms
Putting the device into action at sea presupposes a prior filling with the required quantity of water. The oscillations impressed by the swell on the device and consequently on the liquid masses it contains, lead, in all the compartments, to the elevation of a certain volume of water which progresses by gravity through the valves and pours at the top of the compartments in the supply tank I7 of the hydraulic turbine 20. This volume circulating through the hydraulic turbine 20 falls into the tank 18. The reservoir 18 feeds by gravity the first base chamber of all the compartments such as 36 for the compartment 7. FIG. 5 represents a section along BB of FIG. 1 by the compartments 7 and I4 of the device in action at sea when the float 2 is raised, FIG. 6 when the float 1 is raised, during an oscillation.

Dans cette disposition, les volumes d'eau en circulation dans les compartiments varient avec l'amplitude des oscillations, le volume total d'eau dans le dispositif est maintenu constant grtce à des réservoirs aménagés dans l'espace I9. In this arrangement, the volumes of water circulating in the compartments vary with the amplitude of the oscillations, the total volume of water in the device is kept constant by reservoirs fitted in the space I9.

Cette disposition présente comme avantages de pouvoir utiliser dans la turbine et les clapets une eau filtrée, éventuellement neutralisée, rempote de sables, d'algues ou de produits corrosifs0
Elle offre une faible prise au vent et possède une grande stabilité
L'ancrage se fait à l'aide de 4 lignes de mouillage. This arrangement has the advantages of being able to use filtered, possibly neutralized water in the turbine and the valves, replenishes sand, algae or corrosive products.
It offers little wind resistance and has great stability
The anchoring is done using 4 mooring lines.
