MACHINE UTILISANT LA HOULE POUR EMMAGASINER L'ENERGIE
La présente invention concerne une machine hydraulique placée sur des fonds marins, de différentes profondeurs et transformant i 'é- nergie des vagues en énergie stockable et utilisable au moment opportun.MACHINE USING SURF FOR STORING ENERGY
The present invention relates to a hydraulic machine placed on the seabed, of different depths and transforming the energy of waves into energy that can be stored and used at the appropriate time.
Parmi les dispositifs actuellement destinés â domestiquer la houle il faut noter, en Angleterre et au Japon.Among the devices currently intended to domesticate swell, it should be noted in England and Japan.
- Le batteur ou les "canards" - inventés par Stephen Salter.- The drummer or "ducks" - invented by Stephen Salter.
Le système est articulé autour d'un axe parallèle au front de vague. Sur cet axe se fixent des batteurs. I1 s'agit de corps arrondis vers 1 'arrière et effiles en bec de canard vers l'avant.The system is articulated around an axis parallel to the wave front. On this axis are fixed beaters. They are bodies rounded towards the rear and tapering in duckbill towards the front.
En arrivant, la vague souleve le bec qui retombe ensuite, se soulève de nouveau et ainsi de suite, battant au rythme de la houle autour de son axe. Un système interne de pompes utilise ce mouvement de haut en bas pour comprimer un fluide qui actionne une turbine électrogène.When arriving, the wave lifts the beak which then falls, rises again and so on, beating to the rhythm of the swell around its axis. An internal pump system uses this up and down movement to compress a fluid that powers a generator turbine.
Cette technique pose une difficulté particulière ; la construction d'un axe suffisamment résistant pour supporter ces formidables flexions en mer. En outre, si la récupération de l'énergie est excellente, sa reconversion parait tres difficile.This technique poses a particular difficulty; the construction of an axis strong enough to support these formidable flexions at sea. In addition, if the energy recovery is excellent, its conversion seems very difficult.
- Les radeaux articulés de Cockerell, étudiés depuis I97I. Le principe est assez comparable à celui des "canards". I1 s'agit de grands radeaux comprenant une partie centrale ou se trouvent les unités productrices et deux panneaux avant et arrière articulés.- Cockerell's articulated rafts, studied since I97I. The principle is quite comparable to that of "ducks". These are large rafts comprising a central part where the producing units are located and two articulated front and rear panels.
La vague soulève et baisse periodiquement ces parties mobiles dont le mouvement sera récupéré pour produire de l'énergie.The wave periodically raises and lowers these moving parts whose movement will be recovered to produce energy.
- Le rectificateur mis au point par l'équipe de Robert Russel. I1 se compose d'une sorte de caisse ouverte sur le large et divisée en deux compartiments superposés. La vague haute remplit le réservoir supérieur puis l'eau retombe dansle compartiment inférieur en actionnant au passage une turbine de basse chute. A la différence des systèmes précédents, celui-ci n'est pas flottant mais construit sur le fond ce qui pose de délicats problèmes en raison des marées.- The rectifier developed by Robert Russel's team. It consists of a sort of box open to the sea and divided into two superimposed compartments. The high wave fills the upper tank, then the water falls back into the lower compartment, while driving a low-drop turbine. Unlike previous systems, it is not floating but built on the bottom which poses delicate problems due to the tides.
- La colonne d'eau oscillante inspirée de la filière japonaise du
Dr.MASUDA. On utilise un caisson à clapet dans lequel la montée de l'eau poussée par la vague joue comme un piston pour comprimer la bulle d'air emprisonnée. L'air ainsi comprimé fera tourner une turbine. On peut mettre en batterie une série de chambres pouvant former une sorte de gigantesque moteur multicylindres.- The oscillating water column inspired by the Japanese industry of
Dr. MASUDA. A valve box is used in which the rise of the water pushed by the wave acts like a piston to compress the trapped air bubble. The compressed air will turn a turbine. We can put in battery a series of chambers which can form a kind of gigantic multi-cylinder engine.
- I1 a eté pensé à beaucoup d'autres systèmes
De gigantesques sacs déformables sur lesquels la vague ferait pression pour comprimer l'air, des sortes d'"houléoliennes", éoliennes sous-marines actionnées par les vagues, des trimarans articulés, des sytèmes à piston flottant ancrés au fond, les bouées oscillantes, les aubes basculantes....- I1 has been thought of many other systems
Gigantic deformable bags on which the wave would press to compress the air, kinds of "swells", underwater wind turbines activated by the waves, articulated trimarans, floating piston systems anchored at the bottom, the oscillating buoys, the tilting vanes ....
- Toutes ces "centrales " fourniraient de l'électricité en puissance extrémement variable dans le temps et totalement désyn-chro- nisée par rapport à la consommation. Une telle fourniture d'élec tricité n'est utilisable que si elle peut être stockée, car nul réseau d'utilisation ne peut être branché directement sur une source fantaisiste et au débit imprévisible.- All of these "power stations" would provide electricity with power that is extremely variable over time and totally out of synch with consumption. Such an electricity supply can only be used if it can be stored, since no use network can be connected directly to a fanciful source and at an unpredictable speed.
C'est pour pallier à ces defauts que la machine proposée par cette invention ne produit pas directement l'électricité mais emmagasine une réserve d'eau à une hauteur telle qu'elle puisse être utilisée au moment désiré pour faire tourner des groupes turbines-genérateurs électriques.It is to alleviate these faults that the machine proposed by this invention does not directly produce electricity but stores a reserve of water at a height such that it can be used at the desired time to turn turbine-generator groups. electric.
Principe de la machine.Principle of the machine.
I1 s'agit de pompes animées par les mouvements verticaux irréguliers des vagues, destinées à remonter l'eau à un niveau supérieur permettant l'utilisation modulable de son énergie potentielle ainsi acquise. These are pumps driven by the irregular vertical movements of the waves, intended to raise the water to a higher level allowing the modular use of its potential energy thus acquired.
Un ballon flotteur accompagne, dans le plan vertical de la houle, les vagues dans leur amplitude et leur période. I1 se place, dans le plan horizontal, dans le lit de la vague gràce à des dérives directionnelles immergées.A float balloon accompanies, in the vertical plane of the swell, the waves in their amplitude and their period. It is placed, in the horizontal plane, in the bed of the wave thanks to submerged directional drifts.
Suivant la profondeur à laquelle se trouve la base de la machine fixée au sous-sol marin, il est utilisé : - soit une bielle oscillant dans le plan vertical et tourillonnant dans le plan horizontal, pour les faibles profondeurs (planche NOI) - soit un poussoir guidé dans un bâti vertical, lequel peut-être maintenu par des haubans (planche N"2) ou par un flotteur immergé (planche N"3), ce dernier dispositif étant déjà utilise par les pétroliers,pour les forages en mer, pour relier le ballon-flotteur à des pompes à double effet qui refoulent l'eau admise sous une certaine pression et un certain débit dans un réservoir situé à une certaine hauteur par rapport au niveau moyen de la mer. Depending on the depth at which the base of the machine is fixed to the seabed, it is used: - either a rod oscillating in the vertical plane and swiveling in the horizontal plane, for shallow depths (NOI board) - either a pusher guided in a vertical frame, which can be maintained by guy lines (plate N "2) or by a submerged float (plate N" 3), the latter device being already used by oil tankers, for drilling at sea, for connect the float ball to double-acting pumps which discharge the water admitted under a certain pressure and a certain flow into a tank located at a certain height above average sea level.
Ce réservoir alimentera au moment opportun un ou des groupes générateurs d'électricité. Les pompes hydrauliques alternatives à double effet sont groupées par 2, 3, 4, ou davantage, suivant les conditions générales à remplir.This reservoir will supply one or more electricity generating groups at the appropriate time. The double acting alternative hydraulic pumps are grouped by 2, 3, 4, or more, depending on the general conditions to be fulfilled.
Conditions d'utilisation.Terms of use.
Les vagues de la mer présentent, pour leur exploitation énergetique, un défaut commun à la plupart des énergies renouvelables : la variabilite. The waves of the sea present, for their energy exploitation, a defect common to the majority of the renewable energies: the variability.
I1 faut donc prevoir pour la machine ci-dessous décrite une implantation sur un site - qui soit battu par des vagues venant de loin, pour se presenter de façon relativement ordonnée et monochromatique, - non loin d'une côte qui présente des possibilités de bassinréservoir aux moindres frais. It is therefore necessary to provide for the machine described below an implantation on a site - which is beaten by waves coming from far away, to present itself in a relatively orderly and monochromatic manner, - not far from a coast which presents possibilities of tank-reservoir at the lowest cost.
Les côtes atlantiques, entre les 40ème et 60eme parallèles présentent de telles conditions, c'est à dire - amplitude de la houle de 3 mètres de hauteur moyenne, - longueur d'onde de I50 mètres, - période de IO secondes, soit une vitesse d'une cinquantaine
de kilomètres à l'heure, - différence de hauteur entre mare basse et marée haute de
4 à 6 mètres.The Atlantic coasts, between the 40th and 60th parallels present such conditions, that is to say - amplitude of the swell of 3 meters of average height, - wavelength of I50 meters, - period of IO seconds, that is to say a speed about fifty
kilometers per hour, - height difference between low tide and high tide of
4 to 6 meters.

Planche nO I.Plate nO I.
Machine pour faibles profondeurs.Machine for shallow depths.
Un socle I est fixe horizontalement sur un sol qui est à une distance du niveau moyen de la surface de l'eau calculée en fonction de la hauteur moyenne des marées h, de la hauteur des vagues à marées haute hh, de la hauteur des vagues à marée basse hb.A base I is fixed horizontally on a ground which is at a distance from the mean level of the water surface calculated as a function of the mean height of the tides h, of the height of the waves at high tides hh, of the height of the waves at low tide hb.
Le socle I reçoit un plateau tournant 2 pouvant exécuter une rocation de 360 degrés autour d'un axe vertical creux 3. Une série de roulements à galets ou de billes 4 assure l'appui et les réactions sur un large rayon du plateau tournant 2 sur le socle I.The base I receives a turntable 2 which can execute a rotation of 360 degrees around a hollow vertical axis 3. A series of roller or ball bearings 4 provides support and reactions over a wide radius of the turntable 2 on the base I.
Un double bras 5 reçoit en tourillonnement vertical un pylone en tubes d'acier, soudés et remplis de sable,6 pour augmenter le poids et éviter les vibrations dues aux mouvements de l'eau. A double arm 5 receives in vertical journalling a pylon made of steel tubes, welded and filled with sand, 6 to increase the weight and avoid vibrations due to water movements.
A l'extrémité de ce pylone, â une distance L fonction de la profondeur moyenne pour qu'il reste incliné environ de 30 degres sur l'horizontale, un ballon spherique ou cylindrique à extrémités spériques 7 a un volume tel qu'il demeure à demi-immerge, compensant ainsi le poids du pylone 6. Des dérives 8 le guident dans le lit de la vague.At the end of this pylon, at a distance L as a function of the average depth so that it remains inclined about 30 degrees on the horizontal, a spherical or cylindrical balloon with spherical ends 7 has a volume such that it remains at half immersed, thus compensating for the weight of the pylon 6. Drifts 8 guide it into the wave bed.
A une longueur L I de l'attache tourillonnante sur les bras 5, un axe 9 relie les deux bras du pylone et sert d'entrainement par chape à une pompe hydraulique alternative à double effet IO. At a length L I of the swiveling attachment on the arms 5, an axis 9 connects the two arms of the pylon and serves as drive by clevis to an alternative double-acting hydraulic pump IO.
Deux collecteurs haut et bas II reçoivent l'eau que le mouvement du piston a déplacée, par l'action du flotteur 7 agissant par l'intermédiaire du pylone 6. Ces collecteurs, souples dans le plan vertical, canalisent l'eau vers le centre du plateau 2 dont l'axe creux 3 est muni d'un joint tournant de section correspondant aux collecteurs réunis. De là, part une canalisation I2 qui conduit l'eau refoulée par la pompe à double effet dans une reserve placee en altitude, en fonction de la pression délivrée par la machine.Two upper and lower collectors II receive the water that the movement of the piston has displaced, by the action of the float 7 acting through the pylon 6. These collectors, flexible in the vertical plane, channel the water towards the center of the plate 2, the hollow axis 3 of which is provided with a rotary joint of section corresponding to the collectors assembled. From there, a line I2 leaves which carries the water discharged by the double-acting pump into a reserve placed at altitude, according to the pressure delivered by the machine.
Planche n" 2.Plate n ° 2.
Machine pour profondeurs moyennes.Machine for medium depths.
Un socle I3 est fixé sur le sol. I1 reçoit une colonne creuse I4 maintenue verticale par les haubans I5 ancrés au sol. Une assise I6 sert en meme temps à l'origine des haubans et de supports aux pompes IO dont les collecteurs II rejoignent la colonne creuse I4 qui sert de collecteur général pour le départ de la canalisation
I2.An I3 base is fixed to the ground. I1 receives a hollow column I4 held vertical by the shrouds I5 anchored to the ground. A seat I6 serves at the same time at the origin of the shrouds and supports for the pumps IO whose collectors II join the hollow column I4 which serves as a general collector for the departure of the pipeline
I2.
L'extrémité supérieure de la colonne I4 sert de guide, à un cylindre coulissant I7 qui porte des bras I8 commandant les tiges actionnant les pompes IO. Une butée rotative à double action I9 permet au ballon 7 de se placer dans le lit des vagues grâce aux dérives 8.The upper end of the column I4 serves as a guide for a sliding cylinder I7 which carries arms I8 controlling the rods actuating the pumps IO. A double action rotary stop I9 allows the balloon 7 to be placed in the wave bed thanks to the daggerboards 8.
Planche n 3.Plate 3.
Machine pour plus grandes profondeurs.Machine for greater depths.
Le support utilisé par les pétroliers pour les profondeurs atteintes sur le plateau continental comprend un socle 20 fixé au sol un ensemble rotule 21 permettant à la colonne creuse 22 de decrire un cône d'un certain angle et de délivrer l'eau pompée à la canalisation I2. The support used by oil tankers for the depths reached on the continental shelf comprises a base 20 fixed to the ground a ball joint assembly 21 allowing the hollow column 22 to describe a cone from a certain angle and to deliver the water pumped to the pipeline I2.
La verticalité approximative de la colonne est assurée par un ou plusieurs flotteurs 23 totalement immergés.The approximate verticality of the column is ensured by one or more totally submerged floats 23.
La base des pompes est liée à un bras fixé sur la colonne 22, laquelle coulisse dans un cylindre 24 dépendant du ballon 7 qui communique l'amplitude des vagues aux pompes IO par 1 'intermédiai- re des bras 25.The base of the pumps is linked to an arm fixed on the column 22, which slides in a cylinder 24 depending on the balloon 7 which communicates the amplitude of the waves to the pumps IO via the arms 25.
Dans les 3 cas, il est à redouter un "coup de vent" subit qui augmenterait d'une façon importante l'amplitude des vagues. La pompe comportant des butées naturelles devrait subir un effort inadmissible. C'est pourquoi il est prevu une butée par gravitation, composée d'un filin 26 qui reste mou en amplitude normale, mais soulève, au-dessus d'une certaine amplitude, un poids 27 qui annule la flottabilité du ballon 7. Ce poids peut-être soit un bloc massif de densité élevée soit une chai ne de très forte section qui donne un contre-effort plus progressif. La solution à choisir est en fonction du site et de la profondeur d'implantation de la
machine. In the 3 cases, it is to be feared a sudden "gale" which would significantly increase the amplitude of the waves. The pump with natural stops should be subjected to an unacceptable force. This is why a stop by gravity is provided, composed of a rope 26 which remains soft in normal amplitude, but raises, above a certain amplitude, a weight 27 which cancels the buoyancy of the balloon 7. This weight perhaps either a massive block of high density or a chain of very large section which gives a more progressive counter-effort. The solution to choose depends on the site and the depth of installation of the
machine.
