Abstract

The device has masses (6) whose pendulum-rotary movement is generated by pitching of a float (1) to drive oscillation of a bearing axis (4), where the bearing axis remains in an oscillation plane perpendicular to a face of swell. The masses are fixed at an end of arms (5), where the masses behave like pendulums driven in perpendicular planes at the bearing axis during each inclination of the axis. Distance between the axis and a center of gravity of the masses is adjusted according to frequency of the swell to transform a pendulum movement into rotation.

Description

DESCRIPTION 1 A / LE FLOTTEUR (1) . Le plan de tangage du flotteur doit rester toujours perpendiculaire au front de la houle. Un capteur (16) enregistre en temps réel les caractéristiques de la houle . Dans le cas d'une bouée amarrée au fond, la carène doit être , dans ses dimensions et sa forme, adaptée au site où elle est implantée . Le flotteur (1) porte le bloc (2) auquel il est relié par un double système mécanique . B / LA DOUBLE LIAISON MECANIQUE DU FLOTTEUR (1) AVEC LE BLOC (2) . Un jeu de paliers (3 & 12) solidarise le bloc (2) avec son porteur, le flotteur (1) . Le tangage plus ou moins rapide du flotteur (1), lors de l'arrivée de fa crête de houle , 10 est amorti grâce à une liaison élastique (15), ce qui évite au bloc (2) , contenant tous les organes de pendulo-rotation, un brutal redressement . Par la même occasion, la liaison élastique (15) récupère une partie du moment cinétique du bloc (2) . Deux solutions techniques sont envisageables : a ) La plus simple consiste à utiliser deux ressorts ; 15 b) Plus sophistiquée, la seconde solution requiert des vérins comprimant un gaz stocké dans des réservoirs et un système électromécanique libérant le gaz selon besoins. B / LE MOUVEMENT PENDULO - ROTATIF. Lors du tangage du flotteur (1), l'axe (4) , porté par le bloc (2), oscille à la fréquence de la la houle, ce qui met en mouvement les deux bras (5) , entraînés par leur masse (6).DESCRIPTION 1 A / THE FLOAT (1). The plane of pitch of the float must always remain perpendicular to the forehead of the swell. A sensor (16) records in real time the characteristics of the swell. In the case of a buoy moored at the bottom, the keel must be, in its dimensions and shape, adapted to the site where it is located. The float (1) carries the block (2) to which it is connected by a double mechanical system. B / THE DOUBLE MECHANICAL CONNECTION OF THE FLOAT (1) WITH THE BLOCK (2). A set of bearings (3 & 12) secures the block (2) with its carrier, the float (1). The more or less rapid pitch of the float (1), at the arrival of the wave crest, 10 is damped by an elastic connection (15), which avoids the block (2), containing all the pendulo organs -rotation, a brutal recovery. At the same time, the elastic connection (15) recovers a part of the kinetic moment of the block (2). Two technical solutions are possible: a) The simplest is to use two springs; B) More sophisticated, the second solution requires cylinders compressing a gas stored in tanks and an electromechanical system releasing the gas as needed. B / THE PENDULO - ROTARY MOVEMENT. When pitching the float (1), the axis (4), carried by the block (2), oscillates at the frequency of the swell, which sets in motion the two arms (5), driven by their mass ( 6).

20 Pour éviter tout effet de roulis, les deux bras doivent rester symétriques par rapport au plan dans lequel oscille l'axe (4), plan appelé plan d'oscillation. Cette symétrie, qui implique des sens de rotation opposés, est assurée par un double jeu de renvois d'angle (7 & 8). Les gros pignons ((7) sont solidaires des bras (5), les petits pignons (8) sont solidaires 25 du bloc (2) ; leurs axes moteurs sont situés dans le plan d'oscillation. L'un des pignons (8) entraîne une génératrice (9) tandis que l'autre entraîne un capteur de mouvement (10) , mesurant la vitesse et la position des bras, et surtout un cliquet anti-retour (11) pour assurer et maintenir les sens de rotation des bras. D / LES ORGANES DE REGLAGE . Un système électronique (non représenté) mesure en temps réel l'amplitude et la fréquence de la houle.In order to avoid any rolling effect, the two arms must remain symmetrical with respect to the plane in which the axis (4) oscillates, called plane of oscillation plane. This symmetry, which implies opposite directions of rotation, is ensured by a double set of angle references (7 & 8). The large pinions (7) are integral with the arms (5), the small pinions (8) are integral with the block (2), their motor axes are located in the plane of oscillation. drives a generator (9) while the other drives a motion sensor (10), measuring the speed and position of the arms, and especially a non-return pawl (11) to ensure and maintain the direction of rotation of the arms. D / THE ADJUSTING ORGANS An electronic system (not shown) measures in real time the amplitude and frequency of the swell.

30 L'ajustement de la période d'oscillation des bras (5) s'effectue par un réglage de la position des masses (6) grâce à deux moteurs (13) actionnant deux vis sans fin (14). De même, l'énergie cinétique du bloc (2) , récupérée par la liaison élastique (15), peut être libérée , soit immédiatement ( cas des ressorts non contraints) , soit selon une programmation (non décrite ici) si la solution des vérins est retenue .The period of oscillation of the arms (5) is adjusted by adjusting the position of the masses (6) by means of two motors (13) actuating two worms (14). Similarly, the kinetic energy of the block (2), recovered by the elastic connection (15), can be released, either immediately (in the case of unconstrained springs) or according to a programming (not described here) if the solution of the cylinders is retained.
