Abstract

The invention relates to a device for harnessing the vertical energy and profile of waves, comprising a floating platform that includes a deck (4) which rests on three floating elements (1, 2, 3) and which accommodates a closed circular duct (9) containing a high volume of water called "gush" (10). Said gush (10) is made to rotate using the swirling effect and directly drives a bladed wheel (11) that has a vertical shaft, is rotatably immersed in the water, and drives a power generator (8). Three identical floating elements are disposed under the deck (4) in the form of an equilateral triangle and are always oriented such that any two floating elements are aligned in the direction of propagation of the waves. The device further comprises a mooring system including three identical units that are arranged in an triangle. Each unit has two cables (17) that are tied to the same anchored floating case (18), the cables forming a V and being attached to two mooring points (16) which are 120 degrees apart on a ring located on the deck (4). Said ring (20) allows the power plant to be angularly displaced by 360 degrees using orienting motors (22) and a roller assembly (21) that rolls on a circular rail (23).

Description

DISPOSITIF DE RECUPERATION DE L ' ENERGIE DE LA HOULE MARINE DEVICE FOR RECOVERING THE ENERGY OF THE MARINE HOLLY
L'invention présentée ici concerne un dispositif de récupération de l'énergie de la houle marine pour produire de l'électricité.The invention presented here relates to a device for recovering the energy of the marine swell to produce electricity.
Parmi les technologies connues, on trouve celle de la centrale hydroélectrique flottante tripode à élévateur dont les trois flotteurs captent les oscillations de tangage et de roulis, pour créer un phénomène de rotulage.Among the known technologies, there is that of the floating tripod hydroelectric plant elevator whose three floats capture the pitching and rolling oscillations, to create a swiveling phenomenon.
La Centrale Flottante Tripode Centrifuge (CFTC), objet de la présente demande, permet de transformer directement le mouvement de rotulage généré par la houle en rotation de l'axe de la génératrice électrique.The Centrifugal Tripod Centrifugal Fluid (CFTC), object of the present application, allows to directly transform the swiveling motion generated by the swell in rotation of the axis of the electric generator.
Rappelons le principe du captage de l'énergie de la houle par rotulage (Figures 2, 3, 4): Une plate-forme est constituée par un pont et trois flotteurs disposés en un triangle équilatéral.Recall the principle of collecting swell energy by swiveling (Figures 2, 3, 4): A platform is constituted by a bridge and three floats arranged in an equilateral triangle.
Deux flotteurs sont alignés avec la direction de propagation de l'onde de houle (flotteurs de tangage, côté bâbord). Le troisième flotteur (flotteur de roulis) est à distance égale des deux premiers, du côté tribord. Lorsque les flotteurs de tangage sont à une hauteur identique en chevauchant une crête, le flotteur de roulis est sur la ligne de crête et incline le pont à bâbord. Quand l'onde aura avancé de la moitié de sa longueur, les deux flotteurs de tangage seront à nouveau à même hauteur, mais en chevauchant un creux. Le flotteur de roulis sera dans un creux et inclinera le pont à tribord. Une demi-onde plus tard, le pont aura repris sa position initiale, inclinée à bâbord.Two floats are aligned with the direction of propagation of the wave of waves (pitch floats, port side). The third float (roll float) is at equal distance from the first two, on the starboard side. When the pitch floats are at an identical height overlapping a ridge, the roll float is on the crest line and tilts the deck to port. When the wave has advanced half its length, the two pitch floats will again be at the same height, but overlapping a hollow. The roll float will be in a recess and will tilt the deck to starboard. Half a wave later, the bridge will have returned to its original position, inclined to port.
Durant le cycle (celui de l'onde), le pont de la centrale roule de bâbord à tribord, puis de tribord à bâbord. Simultanément, il tangue: de l'horizontale, il plonge vers l'avant, revient à l'horizontale puis penche vers l'arrière, et retrouve sa position initiale horizontale.During the cycle (that of the wave), the bridge of the station rolls from port to starboard, then from starboard to port. Simultaneously, he pitched: from the horizontal, he plunges forward, returns to the horizontal and then leans backwards, and returns to its initial horizontal position.
La combinaison des deux oscillations roulis et tangage fait décrire à l'axe perpendiculaire au pont un cône inversé. Le pont est soumis à une inclinaison en perpétuel pivotement autour d'un axe vertical. Il s'agit d'un mouvement oscillo-pivotant constituant un rotulage.The combination of the two roll and pitch oscillations causes the axis perpendicular to the bridge to describe an inverted cone. The bridge is tilted in perpetual pivoting about a vertical axis. It is an oscillating-pivoting movement constituting a swiveling.
Cette composition d'oscillations fait décrire à la ligne de plus grande pente du pont incliné un balayage de 360 degrés par cycle de la houle.This composition of oscillations makes describe at the line of greater slope of the inclined bridge a scan of 360 degrees per cycle of the swell.
La Centrale Flottante Tripode Centrifuge (CFTC) transforme sans dispositif intermédiaire complexe le mouvement de rotulage en une rotation de l'axe de la génératrice produisant l'électricité. Ce dispositif est indépendant de toute force de réaction externe, selon le principe du système isolé. Il flotte librement comme une bouée en reposant sur ses trois flotteurs. Il est inchavirable grâce à la disposition triangulaire de ses flotteurs et à la présence d'un stabilisateur annulaire ceinturant le pont ou de plusieurs stabilisateurs périphériques.The Centrifugal Tripod Floating Plant (CFTC) transforms the swivel movement into a rotation of the axis of the generator generating electricity without a complex intermediate device. This device is independent of any external reaction force, according to the principle of the isolated system. It floats freely like a buoy resting on its three floats. It is self-limiting due to the triangular arrangement of its floats and the presence of an annular stabilizer girdling the bridge or several peripheral stabilizers.
La centrale est amarrée afin de ne pas être déplacée par le vent ou les courants marins. L' amarrage est conçu de façon à ne pas contrarier les oscillations dues à la houle, et à permettre l'orientation de la centrale conformément au principe du rotulage et quels que soient les changements d'orientation de la houle.The plant is moored so as not to be displaced by wind or sea currents. The mooring is designed so as not to hinder oscillations due to the swell, and to allow the orientation of the plant in accordance with the principle of swiveling and whatever changes in orientation of the swell.
La technique de construction relève d'un chantier naval banal. L'architecture ne présente aucun défi technique notoire et utilise des matériaux et des composants facilement réalisables et recyclables. Une forme de l'invention est décrite dans les pages suivantes à titre indicatif et nullement limitatif. Les dessins annexés illustrent un mode de réalisation du dispositf.The construction technique is part of a common shipyard. The architecture presents no known technical challenges and uses readily available and recyclable materials and components. One form of the invention is described in the following pages as an indication and in no way limiting. The accompanying drawings illustrate an embodiment of the device.

La Centrale Flottante Tripode Centrifuge (CFTC) comporte différentes parties détaillées ci- après: I)- PONT (Figures 1, 2, 4, 5, 6, 7, 9)The Centrifugal Tripod Centrifugal Fluid (CFTC) comprises various parts detailed below: I) - BRIDGE (Figures 1, 2, 4, 5, 6, 7, 9)
Le pont 4 de la centrale repose sur trois flotteurs 1, 2 et 3, qui forment un triangle équilatéral. Deux quelconques des flotteurs sont toujours alignés selon la direction de. propagation de la houle (par une commande automatique) et grâce à un système d'amarrage spécifique.The bridge 4 of the plant is based on three floats 1, 2 and 3, which form an equilateral triangle. Any two of the floats are always aligned in the direction of. propagation of the swell (by an automatic control) and thanks to a specific mooring system.
A la périphérie de la plate-forme circulaire, un stabilisateur annulaire 5 assure la sécurité de la centrale pour les cas de gîte extrême.At the periphery of the circular platform, an annular stabilizer 5 ensures the safety of the plant for cases of extreme location.
2)- CANAL CIRCULAIRE (Figures 5, 6)2) - CIRCULAR CHANNEL (Figures 5, 6)
Un canal circulaire 9 est ménagé dans le pont. Il contient un volume d'eau captif 10 qui se rassemble, lors du rotulage, dans la partie la plus basse du canal en formant une "goulée". La masse de cette goulée crée un balourd et, du mouvement circulaire de celui-ci, naît une force centrifuge. La goulée tourne dans le canal à la même fréquence que le mouvement de rotulage du pont.A circular channel 9 is formed in the bridge. It contains a volume of captive water which gathers, during swiveling, in the lowest part of the channel forming a "goulée". The mass of this goulée creates an imbalance and, from the circular movement of it, a centrifugal force is born. The groove rotates in the channel at the same frequency as the swiveling motion of the bridge.
Le pont prend ainsi une gîte résultant de trois facteurs: a) le passage de la houle créant le rotulage, b) l'existence du balourd par la goulée, c) l'action de la force centrifuge due au déplacement circulaire de la goulée d'eau. Cet angle de gîte suit, en rotation, la ligne de plus grande pente du pont, constituant ainsi le rotulage autour de l'axe vertical.The bridge thus takes a heel resulting from three factors: a) the passage of the swell creating the swiveling, b) the existence of unbalance by the goulée, c) the action of the centrifugal force due to the circular displacement of the goulée d 'water. This heeling angle follows, in rotation, the line of greatest slope of the bridge, thereby constituting the swiveling around the vertical axis.
La partie supérieure du canal est fermée par un couvercle circulaire 6. Deux vannes, l'une de remplissage l'autre de vidange du canal sont prévues. La centrale peut fonctionner aussi bien avec de l'eau de mer que de l'eau douce. 3)- ROUE A AUBES A AXE VERTICAL (Figures 5, 6)The upper part of the channel is closed by a circular cover 6. Two valves, one filling the other draining the channel are provided. The plant can work with both seawater and freshwater. 3) - VERTICAL AXIS AUBES WHEEL (Figures 5, 6)
L'eau du canal entraîne, dans son déplacement circulaire, la rotation de la génératrice électrique 8 par l'intermédiaire de la roue à aubes 11 montée sur le même axe vertical fixe 24. Si le type de génératrice l'exige, un système multiplicateur de tours peut être prévu sur son axe. _ _The water of the channel causes, in its circular displacement, the rotation of the electric generator 8 via the impeller 11 mounted on the same fixed vertical axis 24. If the type of generator requires it, a multiplier system turns can be provided on its axis. _ _
Le nombre des aubes 12 de la roue est tel que chaque goulée d'eau (qui occupe environ une demi-circonférence du canal) exerce sa poussée sur plusieurs aubes en même temps.The number of vanes 12 of the wheel is such that each tube of water (which occupies about half a circumference of the channel) exerts its thrust on several blades at the same time.
La transformation du mouvement de rotulage du pont en une rotation de la génératrice est directe et de type fluide, sans aucun couplage rigide. Afin d'obtenir un effet de régulation de la rotation, les bras de la roue à aubes peuvent être suffisamment massifs ou associés à un volant d'inertie solidaire de l'axe tournant de la centrale.The transformation of the swiveling movement of the bridge into a rotation of the generator is direct and of fluid type, without any rigid coupling. In order to obtain an effect of regulating the rotation, the arms of the impeller may be sufficiently massive or associated with a flywheel integral with the rotating axis of the central unit.
Selon la longueur d'onde de la houle, le système permet un fonctionnement dans les deux sens de rotation possibles permettant ainsi l'utilisation sur un domaine étendu du spectre de fréquence de la houle. De ce fait, le plan des aubes 12 est positionné perpendiculairement au déplacement circulaire de la goulée d'eau. Les aubes sont maintenues par les entretoises d'aubes 26.Depending on the wavelength of the swell, the system allows operation in both possible directions of rotation thus allowing the use over a wide range of the frequency spectrum of the swell. As a result, the blade plane 12 is positioned perpendicular to the circular displacement of the water channel. The blades are held by the blade struts 26.
4)- GENERATRICE (Figures 5, 6)4) - GENERATOR (Figures 5, 6)
Placée sur l'axe de la roue à aubes, la génératrice 8 tourne grâce au couple engendré par la pression de l'eau de la goulée d'eau sur les aubes. Elle est éventuellement munie d'un multiplicateur de tours.Placed on the axis of the impeller, the generator 8 rotates thanks to the torque generated by the pressure of the water of the water tube on the blades. It is possibly equipped with a multiplier of turns.
Un couvercle étanche 6 coiffant le canal circulaire isole la génératrice de l'eau de la goulée, et une coiffe 7 la protège de l'eau de mer extérieure.A sealed cover 6 covering the circular channel isolates the generatrix from the water of the goulée, and a cap 7 protects it from the seawater outside.
L'énergie électrique délivrée est envoyée à terre par un câble sous-marin.The electrical energy delivered is sent to shore by an underwater cable.
5)- SYSTEME D'AMARRAGE (Figures 1, 5, 6, 7, 10) Sur le pourtour du pont, et à 120 degrés les uns des autres, sont disposés trois points d'amarrage 16. Trois paires de câbles 17 en forme de "V" y sont fixées et vont s'attacher à trois coffres flottants 18, eux-mêmes reliés par des chaînes d'ancrage 28 aux trois corps-morts 19 situés sur le fond marin.5) - MOORING SYSTEM (FIGS. 1, 5, 6, 7, 10) On the periphery of the bridge, and at 120 degrees from each other, are arranged three mooring points 16. Three pairs of cables 17 in form of "V" are fixed and will attach to three floating boxes 18, themselves connected by anchor chains 28 to three mooring 19 located on the seabed.
Afin d'assurer l'alignement de deux des flotteurs perpendiculairement au sens de la houle pour assurer le tangage, les points d'amarrage ne sont pas solidaires du pont lui-même mais d'une couronne circulaire 20 dont le débattement angulaire (de 0 à 360 degrés) permet l'orientation nécessaire du pont et donc celle des flotteurs.In order to ensure the alignment of two of the floats perpendicular to the direction of the swell to ensure the pitch, the mooring points are not integral with the bridge itself but a circular ring 20 whose angular displacement (from 0 360 degrees) allows the necessary orientation of the bridge and therefore that of the floats.
La rotation de la couronne, guidée par un rail 23 et des galets 21, est assurée par des moteurs d'orientation 22 commandés par un système asservi à la direction de la houle. 6)- REMPLACEMENT DE L'AMARRAGE PAR UN PIED TELESCOPIQUE (Figure 8)The rotation of the ring, guided by a rail 23 and rollers 21, is provided by orientation motors 22 controlled by a system controlled by the direction of the swell. 6) - MOTION REPLACEMENT BY TELESCOPIC FOOT (Figure 8)
Pour exploiter l'augmentation de l'amplitude de la houle dans les zones de hauts-fonds, le système d'ancrage par câbles ou chaînes est remplacé par un pied télescopique vertical 13, dont le trépied d'embase 14 est scellé ou posé sur le fond marin. Le tube comporte deux parties coulissant l'une dans l'autre et dont les sections (par exemple carrées ou hexagonales) interdisent toute rotation axiale. Le centre de la plate-forme est alors attaché au sommet du pied télescopique par une articulationTo exploit the increase in the amplitude of the swell in the shallow areas, the anchoring system by cables or chains is replaced by a vertical telescopic leg 13, the base tripod 14 is sealed or placed on the seabed. The tube comprises two parts sliding one inside the other and whose sections (for example square or hexagonal) prohibit any axial rotation. The center of the platform is then attached to the top of the telescopic leg by an articulation
15 de type Cardan. Tous les mouvements angulaires verticaux entre le pont et le pied-support sont libres, ce qui permet à la centrale d'osciller et de rotuler, mais pas de tourner sur elle-même. Cette fonction peut également être obtenue avec une rotule à doigt. . -15 Cardan type. All the vertical angular movements between the bridge and the support foot are free, which allows the center to oscillate and swivel, but not to turn on itself. This function can also be obtained with a finger ball joint. . -
La centrale effectue ainsi son rotulage tout en suivant, grâce aux tubes coulissants, les variations verticales dues au marnage.The plant thus performs its swiveling while following, thanks to the sliding tubes, the vertical variations due to the tidal range.
L'effet de réfraction de l'onde de houle tendant à diriger celle-ci perpendiculairement au rivage dans les zones de hauts-fonds, et le pied télescopique étant fixé à sa base, l'amarrage et son système d'orientation deviennent mutiles. On bénéficie en outre de l'augmentation de l'amplitude de la houle due au shoaling.The refraction effect of the wave of wave tending to direct it perpendicular to the shoreline in the shoal areas, and the telescopic foot being fixed at its base, the mooring and its orientation system become mutile. We also benefit from the increase in swell amplitude due to shoaling.
