Abstract

The generator includes a float strongly made of steel attached to a guide tube. The guide tube slides up and down on a fixed post whose height depends on the size of waves encountered at the operating site. Vertical movement of the float is transmitted by a shaft to a piston sliding in a cylinder with seals at either end. Two connections to the top of the cylinder and two connections to the bottom of the cylinder with appropriate one-way valves allow the piston to do useful work on the hydrodynamic fluid on both up and down strokes. Valves control the flow of fluid from the reservoir into an accumulator to even out irregularities in the flow. From the accumulator the fluid flows via a hydraulic motor back to the reservoir. The hydraulic motor may drive an electric generator or other equipment.

Description

D E S C R -I P T I O N AMENAGEMENT DE DIVERS APPAREILS ET MATERIELS EN VUE DE LA RECUPERATION D'UNE PARTIE DE L'ENRAIE DISPONIBLE DANS LA
HOULE ET LES VAGUES DES MERS ET DES OCEANS
L'invention a pour but la transformation d'une partie de l'énergie naturelle contenue dans la houle et les vagues des mers et océans en énergie mécanique ou électrique.DESCR -IPTION LAYOUT OF VARIOUS DEVICES AND MATERIALS WITH A VIEW TO RECOVERING A PORTION OF THE BODY AVAILABLE IN THE
SURF AND WAVES OF THE SEAS AND OCEANS
The object of the invention is to transform part of the natural energy contained in the swell and waves of the seas and oceans into mechanical or electrical energy.

Le problème posé consiste a utiliser l'énergie contenue dans la houle et les vagues dont : la longueur d'onde, la hauteur (ou creux) la forme, etc... varient pratiquement sans arrêt en fonction : des marées, des courants, des vents, de la forme du fond ou du littoral etc... En outre le matériel doit être très robuste pour pouvoir résister aux fortes tempêtes et à la corrosion marine. The problem posed consists in using the energy contained in the swell and the waves of which: the wavelength, the height (or hollow) the shape, etc ... vary practically without stop depending on: tides, currents, winds, the shape of the bottom or the coast etc ... In addition the material must be very robust to be able to withstand strong storms and marine corrosion.

Le principe de fonctionnement de l'installation est donné par le schéma de la figure 1. The operating principle of the installation is given by the diagram in Figure 1.

Un flotteur lesté repue 1, de construction chaudronnée très robuste, en tôles d'acier, fortement entretoisé et cloisonne est solidaire d'un tube guide repère 2. A weighted float repue 1, of very robust sheet metal construction, made of steel sheets, strongly braced and partitioned, is integral with a guide tube mark 2.

La forme générale du flotteur et ses dimensions sont étudiéesen fonction du lieu dXinstallation et des renseignements hydrographiques connus pour ce lieu. The general shape of the float and its dimensions are studied according to the place of installation and the hydrographic information known for this place.

Le tube guide glisse sur le tube fixe repère 4 grâce à des diabolos de guidage repère 3 les longueurs du tube guide et du tube fixe sont définies en fonction des hauteurs maximales des marées rencontrées au lieu d'installation, auxquelles il faut en outre ajouter les creux maxima possibles. The guide tube slides on the fixed tube mark 4 thanks to guide diabolos mark 3 the lengths of the guide tube and the fixed tube are defined according to the maximum heights of the tides encountered at the place of installation, to which it is also necessary to add the maximum possible lows.

Le flotteur peut ainsi se déplacer verticalement a chaque variation de niveau (entre la basse muter et la pleine mer) provoquée par la houle ou les vagues. The float can thus move vertically at each level variation (between low muter and open sea) caused by swell or waves.

Chaque déplacement vertical est transmis a un piston repère 6 au moyen d'une tige repère 5. Le piston equipé de segments ou joints toriques se déplace dans le corps de pompe repère 7. Les dispositifs de presse-garnltures repère 8 assurent l'étanchéité entre tige de piston et corps de pompe. Ce dernier a évidemment une longueur identique à celle du tube guide ou du tube fixe. Each vertical movement is transmitted to a piston mark 6 by means of a rod mark 5. The piston fitted with segments or O-rings moves in the pump body mark 7. The press-packing devices mark 8 seal between piston rod and pump body. The latter obviously has a length identical to that of the guide tube or the fixed tube.

Le piston se déplacera donc à marée basse à la partie inférieure du corps de pompe et à marée haute à la partie supérieure, toutes les positions intermédiaires étant possibles. The piston will therefore move at low tide at the bottom of the pump body and at high tide at the top, all intermediate positions being possible.

Un réservoir repère 9 contient le liquide hydrodynamique qui, à chaque montée du flotteur remplit la partie inférieure du corps de pompe, et, à chaque descente la partie supérieure. A reference tank 9 contains the hydrodynamic liquid which, with each rise of the float fills the lower part of the pump body, and, with each descent the upper part.

La cylindrée de chaque coup de pompe est fonction du "creux't de la houle ou de la vague. Grâce aux jeux de clapets, le liquide aspiré est ensuite refoulé sous pression jusqu'au moteur hydraulique, repère 11, par le circuit des tuyauteries haute pression. The displacement of each pump stroke is a function of the "trough of the swell or wave. Thanks to the sets of valves, the suctioned liquid is then discharged under pressure to the hydraulic motor, item 11, through the piping circuit high pressure.

Ce circuit haute pression comporte les accessoires traditionnels des circuits hydrauliques : régulateurs de pression, de débit, distributeurs (non représentés sur le schéma pour plus de clarté) mais également une importante batterie d'accumulateurs oléodynamiques repère 10. Ces derniers permettent non seulement d'absorber les à-coups du pompage mais également de stocker une partie de l'énergie en réserve. This high pressure circuit includes the traditional accessories of the hydraulic circuits: pressure regulators, flow regulators, distributors (not shown in the diagram for clarity) but also a large battery of oleodynamic accumulators reference 10. These last not only allow absorb the surges of pumping but also store some of the energy in reserve.

A la sortie du moteur hydraulique le liquide retourne à la bache. At the outlet of the hydraulic motor the liquid returns to the tank.

Le moteur peut entrainer une génératrice électrique ou toute autre machine (repère 12). The motor can drive an electric generator or any other machine (item 12).

L'énergie mise en réserve peut être utilisée dans un moteur hydraulique auxiliaire entrainant une pompe rotative a haute pression. Par le moyen de distributeurs télécommandés on peut refouler du liquide à pression élevée, utiliser le corps de pompe repère 7 en vérin et provoquer - l'immobilisation du flotteur et son blocage à la position
la plus basse si une tempête menace sa robustesse.The energy stored can be used in an auxiliary hydraulic motor driving a high pressure rotary pump. By means of remote-controlled distributors, it is possible to discharge liquid at high pressure, use the pump body, item 7, as a jack and cause - the immobilization of the float and its blocking in the position
the lowest if a storm threatens its robustness.

- l'immobilisation du flotteur et son blocage à la position
la plus haute aux fins d'examen ou de travaux d'entretien.- immobilization of the float and its blocking in position
highest for examination or maintenance work.

- forcer régulièrement l'équipage mobile à parcourir toute
la course aller et retour pour nettoyer au travers de
dispositifs appropriés, la tige 5 : des mousses, algues
et autres accumulations qui pourraient y adhérer. - regularly force the mobile crew to cover the whole
the round trip to clean through
appropriate devices, stem 5: mosses, algae
and other accumulations that may adhere to it.

Il est évident que les distributeurs permettant l'introduction du liquide à très haute pression sur une des faces du piston 6 mettent en même temps le liquide de l'autre face en retour à la bache. It is obvious that the distributors allowing the introduction of the liquid at very high pressure on one of the faces of the piston 6 at the same time put the liquid of the other face in return to the tank.

La régulation de la génératrice et les différentes opérations peuvent se faire par télécommande électrique, ou autre dispositif existant ou à venir (automate programmable, microprocesseur etc...)
La figure 2 représente une unité autonome qui doit pouvoir être utilisée pour des marées de 6 mètres et des vagues avec creux de 2 mètres. Les dispositifs de nettoyage de tige, repère 13, sont installés à peu de distance du presse-garniture inférieur et accessibles par l'intérieur de l'enveloppe cylindrique de protection de l'appareillage.The regulation of the generator and the various operations can be done by electric remote control, or other existing or future device (programmable controller, microprocessor etc ...)
Figure 2 represents an autonomous unit which must be able to be used for tides of 6 meters and waves with hollow of 2 meters. The rod cleaning devices, item 13, are installed a short distance from the lower stuffing box and accessible from the inside of the cylindrical casing for protecting the switchgear.

Le panneau repère 14 sert au groupement des composants hydrauliques et électriques (régulateurs, distributeurs, servo-moteurs etc...)
La ligne de départ de courant électrique repère 15 comporte également les conducteurs de télécommande. Cette ligne est représentée aérienne , mais elle peut aussi bien suivre un parcours sous-marin.The reference panel 14 is used for grouping the hydraulic and electrical components (regulators, distributors, servo motors, etc.)
The reference 15 electric current starting line also includes the remote control conductors. This line is represented aerial, but it can also follow an underwater course.

Cette unité autonome peut être soutenue aux moyens de supports divers - la figure 3 représente l'ensemble supporté par 3 pieux,
enfoncés à la sonnette (ou par d'autres moyens) entretoi
sés par des traverses boulonnées. Haubannage éventuel des
pieux.This autonomous unit can be supported by means of various supports - FIG. 3 represents the assembly supported by 3 piles,
doorbell (or other means) interview
seized by bolted crosspieces. Possible refitting of
pious.

- la figure 4 représente une station autonome fixée sur un caisson béton. - Figure 4 shows an autonomous station fixed on a concrete box.

L'ensemble est aménagé sur la côte puis remorqué à l'empla-
cement déterminé : il suffit d'ouvrir une voie d'eau dans
le caisson pour le faire couler. Cette solution est valable
pour un fond relativement plat.The whole is set up on the coast and then towed to the job.
determined cement: just open a waterway in
the box to make it flow. This solution is valid
for a relatively flat bottom.

- la figure 5 représente une unité autonome monté? sur un
support flottant utilisable pour les grands fonds.- Figure 5 shows a self-contained unit mounted? on a
floating support usable for deep water.

L'ensemble est arrimé à des corps morts ou à des ancres. The whole is secured to dead bodies or anchors.

- la figure 6 représente la vue en coupe transversale d'une
centrale qui peut comporter un nombre quelconque d'éléments. - Figure 6 shows the cross-sectional view of a
central which can include any number of elements.

Toutes les unités de pompage sont installées en ligne sur une structure métallique, en béton ou mixte dont l'axe longitudinal est perpendiculaire à la direction générale de la houle, ou incliné avec un angle déterminé. All the pumping units are installed in line on a metal, concrete or mixed structure whose longitudinal axis is perpendicular to the general direction of the swell, or inclined with a determined angle.

Une galerie permet l'accès depuis le batiment des machines et pupitres de commande à chaque élément de pompage. A gallery allows access from the machinery building and control consoles to each pumping element.

Elle contient les différentes tuyauteries de liaison basse et haute pression qui relient les corps de pompes aux baches et aux moteurs ainsi que les tuyauteries très haute pression permettant l'immobilisation en fin de course haute ou basse d; flotteur de chaque unité.It contains the various low and high pressure connection pipes which connect the pump bodies to the covers and motors as well as the very high pressure pipes allowing immobilization at the end of the high or low stroke d; float of each unit.

Le batiment qui abrite les accumulateurs, les groupes, les pupitres de commande, les réservoirs de liquide hydrodynamique, peut être installé soit sur la structure support, soit à terre. The building which houses the accumulators, groups, control consoles, hydrodynamic liquid tanks, can be installed either on the support structure or on the ground.

Ces installations de production d'énergie doivent être de construction très robuste pour résister au "gros temps" des océans. L'amortissement doit se faire rapidement. Le matériel hydraulique mis en oeuvre est actuellement parfaitement au point et nécessite très peu d'entretien. These energy production facilities must be of very robust construction to withstand the "heavy weather" of the oceans. Amortization must be done quickly. The hydraulic equipment used is currently perfectly developed and requires very little maintenance.

Dans l'état actuel de la technique, pour la mise en oeuvre d'un matériel très classique existant sur le marché, l'huile minérale et les liquides hydrauliques du commerce semblent apporter la solution la plus économique. L'idéal serait l'utilisation d'eau de mer filtrée, qui, éviterait ainsi la pollution toujours possible, par des fuites aux presse-garnitures. In the current state of the art, for the implementation of very conventional equipment existing on the market, mineral oil and hydraulic fluids from the trade seem to provide the most economical solution. The ideal would be the use of filtered seawater, which would thus avoid pollution, which is always possible, through leaks at the stuffing boxes.

Néanmoins, l'évolution de la technologie des tubes revêtus de résines, de plastiques, de nylon etc... laisse espérer l'utilisation de l'eau de mer comme fluide hydrodynamique. Les aciers inoxydables résistant à l'eau de mer sont actuellement très coûteux. Nevertheless, the evolution of the technology of tubes coated with resins, plastics, nylon etc ... gives hope for the use of sea water as hydrodynamic fluid. Seawater resistant stainless steels are currently very expensive.
