Abstract

The device has a roller (34) for circulating in a roller track (35) and for supporting a mass (31) which is carried by a bent arm (32). The arm is fixed along a rotation axis (33), and is integrated with a float. The mass is moved in a pendular motion when a ripple of a swell modifies an attitude of the float and a direction of the rotation axis. The float is balanced such that a platform (11) of the float supporting movable bodies is strictly horizontal when the float is in calm water. The platform has a guide tube (17) passed through a center of a hydraulic thrust of the float.

Description

2911927 DESCRIPTION A / ÉTAT DE LA TECHNIQUE . 1 - Le leu des flotteurs :2911927 DESCRIPTION A / STATE OF THE ART. 1 - The leu of the floats:

Les mouvements de ces derniers ressortissent de deux conceptions : - soit les flotteurs montent et descendent, à l'intérieur de guides ou de tubes, en fonction de la hauteur de la houle ou des vagues ; - soit ils tanguent et roulent en changeant d' assiette selon l' onde de la houle . La présente invention repose sur cette dernière conception.  The movements of the latter come from two conceptions: - either floats rise and fall, inside guides or tubes, depending on the height of the swell or waves; - or they pitch and roll while changing attitude according to the wave of the swell. The present invention is based on this latter design.

2 - Les organes de récupération de l' énemie de la houle : Là encore deux techniques sont utilisées : - des jeux de pistons compriment de I' air ou envoient de l' eau d' un compartiment à l'autre ou actionnent des moteurs hydrauliques. - une masse subissant la gravité agit comme un pendule en considérant le flotteur comme repère fixe et actionne des pompes hydrauliques ou un générateur directement . La présente invention repose sur cette dernière conception .  2 - The recovery devices of wave enemie: Here again two techniques are used: - sets of pistons compress air or send water from one compartment to another or actuate hydraulic motors . - A mass undergoing gravity acts as a pendulum considering the float as a fixed marker and actuates hydraulic pumps or a generator directly. The present invention is based on this latter design.

B / LES ORGANES PASSIFS . 1 - Les flotteurs : Le flotteur est composé principalement d' une plate- forme (11) , d' une carène immergée (12), profilée pour maintenir le flotteur dans son axe de roulis ( perpendiculaire au front de houle) et d' un capot (13). La plate- forme (11) est strictement horizontale quand le flotteur est stabilisé sur une mer calme .  B / PASSIVE ORGANS. Floats: The float consists mainly of a platform (11), a submerged hull (12), profiled to maintain the float in its axis of roll (perpendicular to the wave front) and a hood (13). The platform (11) is strictly horizontal when the float is stabilized on a calm sea.

Elle comprend deux platines (14) , systématiquement placées sur I' axe de tangage du flotteur pour la fixation du dispositif (15) d' ancrage au fond et éventuellement pour relier entre eux plusieurs flotteurs en cas de montage en ligne . Un dispositif étanche (16) permet le passage d' un câble électrique . Elle comporte aussi un tube de guidage (17) , strictement vertical quand le flotteur est stabilisé et passant par le centre de poussée hydraulique du flotteur.  It comprises two plates (14), systematically placed on the pitch axis of the float for fixing the anchoring device (15) at the bottom and possibly to connect them several floats in case of in line assembly. A sealed device (16) allows the passage of an electric cable. It also comprises a guide tube (17), strictly vertical when the float is stabilized and passing through the center of hydraulic thrust of the float.

Ce tube (17), recevant l' axe (33) , imprimera à ce dernier toutes les variations d' assiette du flotteur .  This tube (17), receiving the axis (33), will print to the latter all the variations of attitude of the float.

2 - Les omanes de récupération et de transfert de i' énergie .: Dans la coque du flotteur et dans le capot se trouvent les dispositifs annexes , dont la banalité nous épargne la description . Citons ( liste non exhaustive) : un moteur- alternateur (21) , analogue au démarreur-alternateur que I' on installe actuellement sur certaines voitures , un jeu de batteries (22) , un onduleur- redresseur et la connectique banale pour le transfert du courant à terre via un câble (28) . C / LE SYSTÈME PENDULO - ROTATIF .  2 - Omanes of recovery and transfer of energy: In the hull of the float and in the hood are the ancillary devices, whose banality spares us the description. Let us quote (non exhaustive list): a motor-alternator (21), similar to the starter-alternator that one is currently installed on certain cars, a set of batteries (22), an inverter-rectifier and the banal connectors for the transfer of the current to ground via a cable (28). C / THE PENDULO - ROTARY SYSTEM.

Ce système est emprunté à une précédente invention ( demande n 07 00 605 du 26-01-2007) : il repose sur la tendance naturelle de toute masse pouvant se mouvoir à se positionner au point le plus bas de sa trajectoire imposée , comme tout pendule .  This system is borrowed from a previous invention (request n 07 00 605 of 26-01-2007): it is based on the natural tendency of any mass that can move to position itself at the lowest point of its imposed trajectory, like any pendulum .

1 - La formule basique du système : Une masse (31) coulisse sur un bras coudé (32) solidaire d' un axe (33) et reposant sur un galet (34) roulant dans un couloir circulaire (35) . A chaque inclinaison de I' axe (33) due au changement d' assiette du flotteur , la masse (31) amorce un mouvement pendulaire dans un sens ou dans l'autre et d' amplitude très variable . Ces oscillations pendulaires ne peuvent se transformer en rotation soutenue que dans certains cas de résonance avec I' onde de la houle . Les rotations partielles ou complètes du bras (32) sont directement transmises au générateur (21) via un démultiplicateur (39) . 2 2911927 2 - La formule classique du système : Cette formule repose sur le principe du positionnement fixe de la masse (31) sur le bras (32) . Selon une première variante de la présente invention , une roue à cliquet (36) est fixée sur l' axe (33) , lui permettant de ne tourner que dans un seul sens .Les rotations partielles du bras (32) sont ainsi 5 contraintes dans ce seul sens . Selon une seconde variante , deux dispositifs à billes (37), sur le chemin de roulement (35) du galet (34) sont prévues pour bloquer provisoirement le dit galet et donc la masse (31). La force des ressorts des dispositifs (37) est réglable pour que le galet (35) soit libéré dès que l' inclinaison du flotteur fournit à la masse une énergie potentielle suffisante . 10 Selon une autre variante de la présente invention , un ressort spiral (38) assure une liaison élastique l'axe (33) et le démultiplicateur (39) .  1 - The basic formula of the system: A mass (31) slides on an angled arm (32) integral with an axis (33) and resting on a roller (34) rolling in a circular corridor (35). At each inclination of the axis (33) due to the change of attitude of the float, the mass (31) initiates a pendulum movement in one direction or the other and of very variable amplitude. These pendular oscillations can only be converted into sustained rotation in certain cases of resonance with the wave of the swell. Partial or complete rotations of the arm (32) are directly transmitted to the generator (21) via a reduction gear (39). 2 2911927 2 - The classic formula of the system: This formula is based on the principle of the fixed positioning of the mass (31) on the arm (32). According to a first variant of the present invention, a ratchet wheel (36) is fixed on the axis (33), allowing it to rotate in only one direction. Partial rotations of the arm (32) are thus constrained in this only sense. According to a second variant, two ball devices (37) on the raceway (35) of the roller (34) are provided to temporarily lock said roller and thus the mass (31). The force of the springs of the devices (37) is adjustable so that the roller (35) is released as soon as the inclination of the float provides the mass with sufficient potential energy. According to another variant of the present invention, a spiral spring (38) provides an elastic connection to the axis (33) and the reduction gear (39).

3 - La formule régulée du système : Selon une variante plus élaborée de la présente invention, , les mouvements pendulaires du bras (32) sont transformés en rotation grâce à un ajustement de la période de rotation du système sur la 15 fréquence constatée de la houle . Cet ajustement est simplement obtenu par une modification adéquate de la distance du centre de gravité de la masse par rapport à son axe de rotation (33). Le déplacement sur le bras (32) s 'effectue grâce à une vis sans fin (23) actionnée par le moteur (24) . On utilise éventuellement le couple actif ou passif exercé sur l' axe (33) par le moteur- alternateur (21) . Un calculateur électronique (27) , connecté à un capteur d' assiette (25) fixé au sommet de (33) et 20 à un capteur de direction (26) du bras , commande les moteurs (24) et (21) pour , compte tenu des paramètres enregistrés , positionner la masse (31) à la distance adéquate de I' axe (33) . D I FONCTIONNEMENT DU SYSTÈME PENDULO - ROTATIF .  The Regulated Formula of the System: According to a more elaborate variant of the present invention, the pendular movements of the arm (32) are rotated by adjusting the period of rotation of the system to the observed frequency of the swell. . This adjustment is simply obtained by an appropriate modification of the distance of the center of gravity of the mass relative to its axis of rotation (33). The movement on the arm (32) is effected by means of an endless screw (23) actuated by the motor (24). The active or passive torque exerted on the axis (33) may be used by the alternator motor (21). An electronic computer (27), connected to a trim sensor (25) attached to the apex of (33) and to a steering sensor (26) of the arm, controls the motors (24) and (21) to given the recorded parameters, position the mass (31) at the appropriate distance from the axis (33). D I OPERATION OF THE PENDULO - ROTARY SYSTEM.

Seule sera examinée ici la formule dite "classique" , dans laquelle les mouvements du bras sont limités à des demies rotations .  Only the so-called "classical" formula will be examined here, in which the movements of the arm are limited to half rotations.

25 1 - Les conventions : Pour une bonne compréhension des mouvements du bras (32) et donc de la masse , nous suivrons la position du galet sur son parcours circulaire grâce aux 4 points cardinaux : Nord sera I' avant du flotteur (face au front de houle) , Est à droite, Sud à l'arrière , Ouest à gauche . Les positions du flotteur (son assiette) seront mesurées par l' angle a (+ ou -) : trivialement, pour 30 ces quatre cas de figure, on dira : assiette " horizontale" , "montante", "horizontale" ou "descendante". Les directions du bras (22) portant la masse (21) seront repérés nord, est, sud ou ouest . La direction de la houle est Nord - sud ; les deux billes se trouvent en Nord- Est et Sud- Ouest .  25 1 - Conventions: For a good understanding of the movements of the arm (32) and thus of the mass, we will follow the position of the roller on its circular path thanks to the 4 cardinal points: North will be I 'front of the float (face to the front Swell), East on the right, South on the back, West on the left. The positions of the float (its attitude) will be measured by the angle a (+ or -): trivially, for these four cases, we will say: "horizontal", "rising", "horizontal" or "descending" attitude . The directions of the arm (22) carrying the mass (21) will be marked north, east, south or west. The direction of the swell is North - South; the two marbles are in Northeast and Southwest.

2 - Houle ample * Dans une première hypothèse, nous supposons que l' amplitude de la houle est suffisante pour 35 impulser au flotteur une oscillation régulière autour de son axe de tangage . a) le flotteur est horizontal en partie basse de I' onde (a = 0) . Le bras , orienté NordEst est bloqué. b) La fraction ascendante de l' onde arrive sur le flotteur dont l'assiette fait alors l'angle (+ a) . L' énergie potentielle de la masse " écrase" la bille : le bras est débloqué. c) La masse amorce alors une rotation par l' Est (sens choisi) pour rejoindre le Sud- Ouest , tandis 40 que le déplacement de I' onde ramène I' assiette à l' horizontale (a = 0) . d) Arrivé en Sud- Ouest, le bras est de nouveau bloqué par I' autre bille. Un autre cycle s' amorce .  In a first hypothesis, we assume that the amplitude of the swell is sufficient to drive the float a regular oscillation about its pitch axis. a) the float is horizontal in the lower part of the wave (a = 0). The arm, oriented NorthEst is blocked. b) The ascending fraction of the wave arrives on the float whose attitude then makes the angle (+ a). The potential energy of the mass "crushes" the ball: the arm is unlocked. c) The mass begins then a rotation by the East (direction chosen) to join the Southwest, while 40 the displacement of the wave brings the plate back to the horizontal (a = 0). d) Arrived in South-West, the arm is again blocked by the other ball. Another cycle begins.

2 - Mer calme:, * Dans une seconde hypothèse, si I' amplitude de la houle est insuffisante et que le bras se trouve libre , les petites oscillations du flotteur I' amèneront petit à petit , grâce au cliquet (36) , sur l' une des billes où , bloqué , il attendra l' arrivée d' une houle plus ample pour exécuter une demie rotation . 3  2 - Calm Sea: * In a second hypothesis, if the amplitude of the swell is insufficient and the arm is free, the small oscillations of the float I 'will bring little by little, thanks to the pawl (36), on the one of the balls where, blocked, it will wait for the arrival of a swell ampler to execute a half rotation. 3
