Abstract

The appts. has a vertical axis carrying horizontal arms each supporting a vertical vane pivoted at one edge and having a stop limiting its travel, so the vane is held across the wind or water flow while turning with the flow, and is free to turn edge on to the flow as the return motion brings the vane into the flow. The vertical axis (A) carries a rigid structure (B) having horizontal arms each with a vertical shaft mounted near the end. This shaft is attached near one vertical edge of a vane. Fluid flow tends to align the vane with the flow direction. A stop (D) fixed to each arm limts the travel of the vane in order that it presents a component of area to the fluid flow while the arm moves with the flow. As the rotation carries the vane into opposition with the flow the vane is free to rotate to present only an edge to the flow.

Description

DESCRIPTION
Solienne à axe vertical et pales mobiles.DESCRIPTION
Solienne with vertical axis and movable blades.

L'invention décrite concerne les machines destinées à convertir l'énergie éolienne en énergie mécanique, soit dans le but de produire du courant électrique, par exemple, soit dans le but de propulser un engin mobil.The invention described relates to machines intended to convert wind energy into mechanical energy, either for the purpose of producing electric current, for example, or for the purpose of propelling a mobile vehicle.

les machines les plus répendues sont à axe horizontal comportant de 2 à plusieurs pales du type "hélice". L'inconvétient majeur de ce type d'appareils est qu'ils sont obligatoirement tributaires d'un dispositif servant à diriger les pales face au vent, ce qui à pour résultat de les stopper lors de brusques changements de direction de vent ou lors de tourbillons. De plus, selon que l'on veut actionner une géhératrice ou une pompe, il faut deux types d'appareils, un à rotation rapide (2 pales) un à rotation lente (assez grand nombre de pales). les éoliennes à axe vertical avec pales en S et celles à pales en demi sphères ont un rendement médiocre. Les éoliennes expérimentales à axe vertical, constituées de lames cintrées en demi cercle ne sont pas puissantes elles non plus. the most widely used machines have a horizontal axis comprising from 2 to several blades of the "propeller" type. The major drawback of this type of aircraft is that they are necessarily dependent on a device used to direct the blades facing the wind, which results in stopping them during sudden changes in wind direction or during whirlwinds . In addition, depending on whether you want to operate a generator or a pump, you need two types of device, one with fast rotation (2 blades) and one with slow rotation (quite a large number of blades). vertical axis wind turbines with S-shaped blades and those with hemispherical blades have poor performance. Experimental wind turbines with a vertical axis, made up of blades curved in a semicircle, are not powerful either.

Enfin aucune éolienne n'est capable de fournir assez de puissance pour propulser dans de bonnes conditions un véhicule, qu'il soit terrestre on marin.Finally, no wind turbine is capable of providing enough power to propel a vehicle in good conditions, whether terrestrial or marine.

L'appareil objet de l'invention fonctionne de façon identique, quelque soit la direction du vent. Toutes les surfaces opposants une résistance au vent sont motrices. La vitesse de rotation est relativement constante ( Quand la vitesse du vent double, la vitesse de rotation n'augmente que de 209/0 en moyenne, alors que le couple est multiplié par 8.The device which is the subject of the invention operates in the same way, whatever the wind direction. All surfaces opposing wind resistance are driving. The speed of rotation is relatively constant (When the wind speed doubles, the speed of rotation only increases by 209/0 on average, while the torque is multiplied by 8.

La conception de cet appareil en fait un capteur d'énergie éolien -ne polyvalent à haut rendement, d'une souplesse d'utilisation et propre à actionner indifféremment une pompe, une génératrice etc, ou même un véhicule.The design of this device makes it a versatile high-efficiency wind energy sensor, flexible in use and capable of operating either a pump, a generator, etc., or even a vehicle.

L'appareil objet de l'invention est constitué d'un axe vertical pivotant, sur lequel sont accrochés à son sommet et à sa base, des bras, destinés à supporter à leurs extrémités, des pales mobiles, guidées dans leurs mouvements par des cales. Les pales étant destinées à faire tourner l'ensemble sous la pression du vent. le dessin annexé, montre à titre d'exemple, l'une des reac lisations possible conforme à la présente invention Suivant le dessin, l'appareil comporte trois pales mobiles pouvant girer autour de leur axe d'environ 1000 par rapport à l'alignement de l'axe central. quand le vent vient fraper la pale Cl dans la position 00, celle-ci se plaque contre la cale D et se trouve poussées en arrière jusqu'à 1800 ou elle se retourne sur elle même de 1000, calée par une cale E, continuant de tracter l'en- semble jusqu'à 2250 (le retournement de la paie à 1800 est du au fait que la pale qui recevait la pression du vent à gauche avant 1800 la reçoive après)1800). La pale 02 qui se trouvait à la position 1200 quand C1 était à 00 continue dans le même temps sa poussée jusqu'à 2250 (après retournement à 1800) Tandis que C3 qui se trouvait à 2400 et en alignement du vent quand Cl- était à 00, remonte jusqu'à 0 ou elle prend la place initiale de CI, et le cycle recommence.The device object of the invention consists of a vertical pivoting axis, on which are hung at its top and at its base, arms, intended to support at their ends, movable blades, guided in their movements by wedges . The blades being intended to rotate the assembly under the pressure of the wind. the accompanying drawing shows, by way of example, one of the possible reac lations in accordance with the present invention. According to the drawing, the apparatus comprises three movable blades capable of gyrating around their axis of about 1000 relative to the alignment. of the central axis. when the wind hits the blade Cl in position 00, it is pressed against the wedge D and is pushed back until 1800 or it turns on itself 1000, wedged by a wedge E, continuing to tow the whole unit until 2250 (the reversal of payroll at 1800 is due to the fact that the blade which received the wind pressure to the left before 1800 receives it after) 1800). The blade 02 which was at position 1200 when C1 was at 00 continues at the same time its thrust until 2250 (after reversal at 1800) While C3 which was at 2400 and in alignment with the wind when Cl- was at 00, goes back to 0 or it takes the initial place of CI, and the cycle begins again.

A noter: que les pales restent plaquées contre les cales* parceque leur; axes sont déportés vers l'extérieur, et qu'elles se retournent à la position 1800 pour la même raison.Note: that the blades remain pressed against the shims * because their; axes are offset to the outside, and they return to position 1800 for the same reason.

Que les pales sont calées de O à 1800 par les cales D et de 1800 à 2400 par les cales E. Que le sens de rotation est défini par la position des cales. (selon qu'elles se trouvent placées à gauche
ou à droite de la pale). Que le nombre et la dimention des pales représentées sur le dessin ne sont pas limitatifs A noter aussi qu'en permanence, deux pales sur trois sont motrices et que ce rapport serait le même avec un nombre supérieur de pales ex: avec six pales, quatre seraient motrices en permanence.That the blades are calibrated from O to 1800 by the shims D and from 1800 to 2400 by the shims E. That the direction of rotation is defined by the position of the shims. (depending on whether they are placed on the left
or to the right of the blade). That the number and the dimension of the blades represented on the drawing are not limiting. Note also that permanently, two blades out of three are driven and that this ratio would be the same with a higher number of blades ex: with six blades, four would be driving all the time.

L'appareil fonctionne aussi avec deus pales, toujours avec le même rapport (pales motrices sur 2250). De plus cet appareil, peut être mû par énergie hydrolique, et un bon rendement est obtenu.The device also works with two blades, always with the same ratio (driving blades on 2250). In addition, this device can be driven by hydro energy, and a good yield is obtained.

en jumelant deux appareils placés dans 11 alignement du courant, l'un tournant à l'inverse de l'autre ( spécialement quand le courant est canalisé) le capteur d'énergie éolienne, objet de l'invention peut servir à actionner des générateurs de courants électriques pour suppléer aux fournitures traditionnelles de courant,ou pour l'alimentation des balises, réémetteurs et autres, en mer ; à actionner des pompe pes à eau, partout ou il est malaisé de transporter une énergie quelconque, parce que trop éloigné ou trop cher, en particulier dans les pays arides ou en voie de développement. Enfin, grace à la vitesse de rotation relativement constante, son couple très puissant, ne se souciant pas de la direction du vent, cet appareil est capable de propulser un véhicule, en l'occurence un "bateau". by pairing two devices placed in alignment with the current, one rotating in reverse of the other (especially when the current is channeled) the wind energy sensor, object of the invention can be used to activate generators of electric currents to supplement traditional supplies of current, or for powering beacons, transmitters and others, at sea; to operate water pumps, wherever it is difficult to transport any energy, because it is too far away or too expensive, especially in arid or developing countries. Finally, thanks to the relatively constant speed, its very powerful torque, not caring about the wind direction, this device is capable of propelling a vehicle, in this case a "boat".
