Abstract

Mini generator of electricity by recovery of the energy from the swell. A sealed casing encloses a fixed plate 1 equipped with a circle of coils on cores 2 facing which magnets 5 fixed to a rotating plate 4 form an alternator. At the centre of the plate 1 a vertical spindle 3 serves as a pivot for the plate 4, as a support for the fixed disc 9 then, at its top, for a bearing supporting a rotating arm 10. At the end of this arm a fixed wheel 8 matched with a free wheel 7 turns freely. At the other side of the arm a free wheel 6 and then a weight 11 are mounted. The free wheels 6 and 7 engage on the plate 4. When the weight 11 turns in the clockwise direction the arm 10 pivots in the same direction, the free wheel 6 being in blocked mode drives the plate 4 which produces electricity in the coils 2. When the weight 11 sets off in the opposite direction the wheel 6 freewheels while 8 drives 7 which, being in blocked mode, drives the plate 4 still in the same direction. The device according to the invention is intended to supply power to marine buoys of all types, as well as to persons shipwrecked at sea, or to lifeboats.

Description

La présente invention concerne l'alimentation en énérgie électrique des boucles marines de tous types : bouées météo, dérivantes, de signalisation, de détresse, de sauvetage. The present invention relates to the supply of electrical energy to marine loops of all types: weather buoys, drifters, signaling, distress, rescue.

Les dispositif3 connus à ce Jours utilisent s la compression et décompression de l'air dans un cylindre vertical, tra- versant la bouée de haut en bas; ce système comprime l'air qui agit sur une turbine, qui entrain un petit alternateur. Ce ype de générateur n'est réalisable que sur des bouées d'une certaine importance. D'autre part le mouvement comporte des temps morts. The devices 3 known to date use s compression and decompression of air in a vertical cylinder, passing through the buoy from top to bottom; this system compresses the air which acts on a turbine, which drives a small alternator. This generator type is only achievable on buoys of a certain size. On the other hand, the movement includes dead times.

Pour les petites bouées de detresse genre " Argos te une batterie incorporée assure une autonomie de 50 heures environ. For small distress buoys like "Argos te a built-in battery ensures autonomy of about 50 hours.

La majorité des naufrages ont on général lieu par gros temps
Vautre part la dures de survie des naufrages est liée à la rapidité des secours Des la tombée de la nuit les reherches sont interrompues par impossibilité de localisation précise.The majority of shipwrecks usually take place in heavy weather
On the other hand, the hard survival of shipwrecks is linked to the speed of the rescue. As soon as night falls, the search is interrupted due to the impossibility of precise location.

Le dispositif selon l'invention permet de créer de l'énergie clectrique à partir des mouvements de la houle. The device according to the invention makes it possible to create clectric energy from the movements of the swell.

Un caisson circulaire en matériau léger et étanche en forme de galette renferme un plateau de base qui sert de lest Fig 9 (1). Sur ce plateau sont disposés en cercle des pions en acier doux Fig 1 (2) sur lesquels sont bobinées des spires de fil de cuivre émaillé. Au centre du plateau est soudé un axe vertical Fg 1 (3) qui sert de point d'appui à un plateau tournant Fig 1 (4) sur la périphérie duquel sont fixés des aimants Fig 1 (5)
Les aimants sont disposés de manière à se trouver en face des pions Fig 1 (2).A circular box made of light, waterproof material in the form of a wafer contains a base plate which serves as ballast Fig 9 (1). On this plate are arranged in a circle pawns in mild steel Fig 1 (2) on which are wound coils of enamelled copper wire. In the center of the plate is welded a vertical axis Fg 1 (3) which serves as a fulcrum for a rotating plate Fig 1 (4) on the periphery of which magnets are fixed Fig 1 (5)
The magnets are arranged so as to face the pins Fig 1 (2).

Le plateau lest Fig 1 (1) et le plateau tournant Fig d (4) constituent un alternateur à vitesse lente. The ballast plate Fig 1 (1) and the turntable Fig d (4) constitute a slow speed alternator.

Le plateau tournant Fig 1 (4) est percé d'une rangée de trous en forme de cercle correspondants à la denture de deux roues- libres Fig 9 (6)-(7). Monte sur l'axe vertical Fig 1 (3) audessus du plateau tournant se trouve un disque fixe Fig 1 (9) lui-m8me percé d'une série circulaire de trous correspondants à la denture d'une roue-fixe Fig 1 (8). En bout de l'axe vertical se trouve un bras monté sur roulement Fig d (10) qui sert d'axe support à l'ensemble Jumelé roue-libreXroue-fixe Fig d (7)-(8) et à l'autre extrémité à la roue-libre Fig 1 (6),et,se termine par un poids Fig 9 (11).  The turntable Fig 1 (4) is pierced with a row of circle-shaped holes corresponding to the teeth of two freewheels Fig 9 (6) - (7). Mount on the vertical axis Fig 1 (3) above the turntable is a fixed disc Fig 1 (9) itself drilled with a circular series of holes corresponding to the teeth of a fixed wheel Fig 1 (8 ). At the end of the vertical axis is an arm mounted on a bearing Fig d (10) which serves as a support axis for the Twin-wheel-free assembly Fixed-wheel Fig d (7) - (8) and at the other end freewheel Fig 1 (6), and, ends with a weight Fig 9 (11).

La fig 2 suivant la présente invention donne un exemple du processus du mouvement créé par la houle. Fig 2 according to the present invention gives an example of the process of movement created by the swell.

Supposons comme point de départ Fig 2 que le poids (11) soit dans la position F et que la houle soulève le point E en abaissant le point C. Le poids (11) par la force d'inertie va tendre à partir du point F vers C. La roue-libre (6) se trouvant dans son sens bloqué va entraîner le plateau tournant (4) ce qui va créer un champ magnétique alternatif et induire un courant dans le bobines entourant les pions (2) d'où il y aura production d'électricité. Le poids (11) emporté par son élan, va passer le point C et se diriger vers le point D. Assume as a starting point Fig 2 that the weight (11) is in position F and that the swell raises point E by lowering point C. The weight (11) by the force of inertia will tend from point F towards C. The freewheel (6) being in its blocked direction will drive the turntable (4) which will create an alternating magnetic field and induce a current in the coils surrounding the pins (2) from where there will have electricity generation. The weight (11) carried by its momentum, will pass point C and move towards point D.

A cet instant deux alternatives vont devenir possibles :
10/ La houle s'est inversée faisant basculer le générateur le point E s'abaissant, tandisque le point C se soulève; le poids (11) continue sa course de D vers E, le mouvement s'accélère, le plateau (4) prend vitesse et force.... ou .....At this moment two alternatives will become possible:
10 / The swell is reversed causing the generator to tilt the point E lowering itself, while the point C rises; the weight (11) continues its course from D to E, the movement accelerates, the plate (4) takes speed and force .... or .....

20/ La houle continue à se creuser soulevant davantage le point B et abaissant encore plus le point C. Le poids (11) va revenir de D vers C; la roue-libre (6) va cliqueter tandisque la roue-fixe (8) va tourner en s'engrenant dans les tous du disuque (9).La roue-fixe (8) étant Jumelée à la rouelibre (7) va entraider cette dernière, quise trouvant dans sa position bloquée, va par rotation obliger le plateau (4) à continuer sa course toujours dans le même sens. 20 / The swell continues to widen, raising point B more and lowering point C even more. The weight (11) will return from D to C; the freewheel (6) will click while the fixed wheel (8) will turn while meshing in all of the disc (9). The fixed wheel (8) being twinned with the freewheel (7) will help this last, which finding in its locked position, will by rotation force the plate (4) to continue its race always in the same direction.

Le dispositif suivant l'invention aura transformé un mouvement alternatif à balancier, en un mouvement circulaire à sens constant et à récupération des deux alternances. The device according to the invention will have transformed a reciprocating pendulum movement into a circular movement in a constant direction and with recovery of the two half-waves.

Le dispositif aura bénéficié de l'inertie des pièces en mouvement en évitant les temps morts par inversion. The device will have benefited from the inertia of the moving parts by avoiding downtime by inversion.

Le courant électrique généré sera de l'alternatif. Par un simple Jeu de diodes ce courant sera redressé pour obtenir du continu capable de recharger une batterie et de faire fonctionner.un émetteur, ou une radio-balise, ou un radio-phare. The electric current generated will be an alternative. By a simple set of diodes this current will be rectified to obtain continuous capable of recharging a battery and operating a transmitter, or a radio beacon, or a radio headlight.

Le surplus d'énergie pourra être utilisé dans un petit phare à éclats, qui de nuit sera visible en mer à plusieurs miles, et permettra le repérage et le sauvetage des naufragés.  The surplus energy can be used in a small flashing beacon, which at night will be visible at sea for several miles, and will allow the tracking and rescue of the shipwrecked.
