Abstract

The vertical axis wind turbine gives improved omnidirectional capture of wind energy with maximum efficiency. The turbine is used to drive electric generators. The turbine is mounted atop a polygonal structure with tapered air ducts facing radially outward. The horizontal turbine is mounted at the centre of the structure, and has curved blades carried on a rectangular frame. The blade mounting frame is coupled to electric generators mounted above and below, and an automatic clutch couples the shaft of the lower generator to a brake. The absence of a central shaft in the centre of the turbine improves the aerodynamics giving improved performance.

Description

L'objet de l'invention concerne un moteur actionné par le vent. The object of the invention relates to a wind powered motor.

I1 est destiné à améliorer la captation de l'énergie découlant des vents et sa transformation en courant électrique. It is intended to improve the capture of the energy arising from the winds and its transformation into electric current.

Dans les dispositifs connus les capteurs étaient généralement à axes horizontaux ou verticaux de sorte que les pales ou ailes avaient soit des sections dégressives, soit un espace neutre diminuant les surfaces de captation et le rendement. In known devices, the sensors were generally with horizontal or vertical axes so that the blades or wings had either declining sections or a neutral space reducing the capture surfaces and the yield.

Le dispositif suivant l'invention supprime ces inconvénients et permet d'utiliser toute la surface de la voilure sans solution de continuité, tout en assurant omnidirectionnellement la captation des vents avec effet accélérateur. The device according to the invention eliminates these drawbacks and makes it possible to use the entire surface of the airfoil without a solution of continuity, while ensuring omnidirectionally the capture of the winds with accelerating effect.

I1 est constitué par la combinaison d'une turbine horizontale à quatre pales, sans axe médian mais montées sur un cache tournant dont les axes entretoisés supportent les flasques solidaires de deux arbres opposés entrainant deux dynamos, avec embrayage automatique, frein à tambour et d'un capteur circulaire omnidirectionel. I1 is formed by the combination of a horizontal turbine with four blades, without a central axis but mounted on a rotating cover whose braced axes support the flanges secured to two opposite shafts driving two dynamos, with automatic clutch, drum brake and an omnidirectional circular sensor.

Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente la turbine vue en plan.In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows the turbine in plan view.

La figure 2 est une vue en élévation des capteurs. Figure 2 is an elevational view of the sensors.

La figure 3 est une vue en coupe transversale du dispositif. Figure 3 is a cross-sectional view of the device.

La turbine (Fig 1) comporte quatre pales 1, 2, 3, 4 avec courbure et profils capteurs combinés. Leur longueur est telle que le vent sortant l'une des pales, puisse aller frapper la palette diamétralement opposée. The turbine (Fig 1) has four blades 1, 2, 3, 4 with curvature and combined sensor profiles. Their length is such that the wind exiting one of the blades can strike the diametrically opposite pallet.

Leur rapport hauteur-longueur est au moins de 1 à 5 ou 6. Their height-to-length ratio is at least 1 to 5 or 6.

Ces quatre palettes sont montées dans une armature quadrangulaire 5 avec entretoises supérieures et inférieures 6, 7 diamétralement implantées de façon que leur point de croise ment soit solidaire d'un flasque 8, 9, supérieur et inférieur cerclant et positionnant l'arbre de rotation 10, 11, relié aux dynamos 12, 13 avec embrayage automatique 14 et frein tambour 15. These four pallets are mounted in a quadrangular frame 5 with upper and lower spacers 6, 7 diametrically located so that their cross point is secured to a flange 8, 9, upper and lower encircling and positioning the rotation shaft 10 , 11, connected to the dynamos 12, 13 with automatic clutch 14 and drum brake 15.

La double dynamo empeche et modère l'emballement de la turbine. The double dynamo prevents and moderates the runaway of the turbine.

Ces axes déportés, ainsi que les organes reliés, sont pourvus de roulement à billes. These offset axes, as well as the connected members, are provided with ball bearings.

Cette armature motrice quadrangulaire tournant en même temps que les hélices de la turbine est montée dans l'axe des capteurs. This quadrangular drive frame rotating at the same time as the turbine propellers is mounted in line with the sensors.

Ces capteurs (Fig 1, 2, 3) sont constitués par un bati 16 supportant une série de capteur suivant une implantation polygonale déterminant une surface de captation circulaire et de ce fait omnidirectionnelle. These sensors (Fig 1, 2, 3) are constituted by a frame 16 supporting a series of sensors following a polygonal implantation determining a circular and therefore omnidirectional sensing surface.

Chaque capteur est de section pyramidale tronquée avec large ouverture 17 extérieure et petite base 18 orientée vers l'axe entourant périphériquement les hélices centrales. Each sensor is of truncated pyramidal section with large external opening 17 and small base 18 oriented towards the axis peripherally surrounding the central propellers.

Chaque capteur avec ouverture rectangulaire présentant une largeur supérieure à la hauteur constitue un accélérateur aéro-dynamique. Each sensor with rectangular opening having a width greater than the height constitutes an aerodynamic accelerator.

Leur opposition diamétrale favorise l'admission et l'évacuation de la veine motrice de sorte que le vent sortant de l'une des pales, continue son action sur la palette diamétralement opposée. Il s'en suit que la force du vent est intégralement captée et n'est évacuée qu'après avoir transmis la presque totalité de sa puissance. Their diametrical opposition favors the admission and evacuation of the motor vein so that the wind leaving one of the blades continues its action on the diametrically opposite pallet. It follows that the force of the wind is fully captured and is only evacuated after having transmitted almost all of its power.

Ces capteurs peuvent aussi bien s'utiliser sur des emplacements fixes qu'en tous lieux, même sur des mobiles tels que véhicules ou autres. These sensors can be used on fixed locations as well as anywhere, even on mobiles such as vehicles or others.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour celà la conception générale de l'invention qui vient d'erre décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as indeed the materials used for their manufacture, without changing the general conception of the invention which has just been described.
