Abstract

The vertical axis wind turbine includes a cylindrical rotor (10) with blades parallel to the axis. Mounted on the same axis is an arm (7) extending along a radius of the cylinder, with a vane (3) on the outer end. The other part of the arm extending in the opposite direction supports a triangular wind deflector (1). This normally serves to direct air correctly into the cylinder, and cooperates with a rear deflector (2). A braking mechanism (8) is arranged to apply a braking force if the speed of the turbine becomes excessive. The mechanism also alters the position of the triangular deflector in order to reduce the force applied by the incident air, allowing it only to strike a reduced area of the cylinder.

Description

EOLIENNE A DEFLECTEURS MOBILES
La présente invention concerne les éoliennes ; appare utilisés pour produire de l'énergie avec la force du vent.MOBILE DEFLECTORS WIND TURBINE
The present invention relates to wind turbines; used to generate energy with the force of the wind.

I1 existe deux grands types d'éoliennes
1- à axe horizontal qui nécessite un renvoi d'angle
2- à axe vertical qui offre une prise au vent "négati quand les pales ne captent pas l'énergie.There are two main types of wind turbines
1- with horizontal axis which requires a bevel gear
2- with vertical axis which offers a hold in the wind "negati when the blades do not capture the energy.

L'éolienne selon l'invention est à axe vertical carac térisée par un déflecteur mobile qui dévie le vent qui produirait un effet "négatif" pour le propulser sur les pales qui transmette une force positive, c'est-à-dire allant dans le sens désiré de rotation de la turbine. The wind turbine according to the invention has a vertical axis characterized by a mobile deflector which deflects the wind which would produce a "negative" effect to propel it on the blades which transmits a positive force, that is to say going in the desired direction of turbine rotation.

Un deuxième déflecteur maintient le flux d'air dans les pales en lui donnant un mouvement rotatif. Les deux déflecteu sont solidaires l'un de l'autre et sont maintenus dans la positio adéquate par rapport au vent par une dérive fixée elle aussi sur un bras rotatif. U, dispositif de frein est prévu pour ralentif 1 turbine en cas de tempête. Ce frein, est composé par un aileron qu offre en position normale une faible prise au vent. Dès que ce dernier dépasse un certain seuil l'aileron se soulève et offre le maximum de résistance au flux d'air et cela agit sur un patin de qui frotte sur la partie supérieure de la turbine. Des masselotte, permettent de facilement régler le seuil à partir duquel on souha que le frein entre en action. A second deflector maintains the air flow in the blades by giving it a rotary movement. The two deflectors are integral with each other and are kept in the correct position relative to the wind by a drift also attached to a rotating arm. U, brake device is provided to slow down 1 turbine in the event of a storm. This brake is made up of a fin which in normal position offers little wind resistance. As soon as the latter exceeds a certain threshold the fin lifts and offers the maximum resistance to the air flow and this acts on a pad which rubs on the upper part of the turbine. Weights make it easy to adjust the threshold from which we want the brake to come into action.

Figures 4 et 5. Figures 4 and 5.

Ce freinage a deux effets
1- ralentir la vitesse de rotation de la turbine
2- modifier l'emplacement du déflecteur 1 qui diminue l'efficacité du vent sur les pales et dans la position extrême découvre les ailerons qui "remontent1, au vent.This braking has two effects
1- slow down the turbine rotation speed
2- modify the location of the deflector 1 which decreases the efficiency of the wind on the blades and in the extreme position discovers the fins which "go up1, to the wind.

Dès que le vent baisse en dessous du seuil désiré l'a du frein 9 retombe par son propre poid et l'éolienne retourne en I tion normale. As soon as the wind drops below the desired threshold the brake 9 drops by its own weight and the wind turbine returns to normal I tion.

Telle qu'elle est représentée cette éolienne à déflec mobile 1 est composée par une turbine normale a numbre de pale quelconque et de forme aérodynamique appropriée. La turbine est solidaire de l'axe principal 12 grâce aux deux roulements (coniques de préférence) 5 et 6. As shown, this mobile deflec wind turbine 1 is made up of a normal turbine with any blade number and an appropriate aerodynamic shape. The turbine is integral with the main axis 12 thanks to the two bearings (preferably tapered) 5 and 6.

Une poulie 13 permet d'installer la courroie transmettant l'énergie. à l'alternateur ou tout autre appareil. Au sommet de l'axe 12 est fixé un roulement b solidaire du bras rotatif 7. A pulley 13 makes it possible to install the belt transmitting the energy. to the alternator or any other device. At the top of the axis 12 is fixed a bearing b secured to the rotary arm 7.

Ce dernier maintient le déflecteur 1 qui dévie le flux d'air vers les pales de la turbine qui transmettent une force "positive". Le déflecteur 2 compense en partie l'effet du vent sur le déflecteur 1 et maintient le flux aérien dans la turbine. The latter maintains the deflector 1 which deflects the air flow towards the blades of the turbine which transmit a "positive" force. The deflector 2 partially compensates for the effect of the wind on the deflector 1 and maintains the air flow in the turbine.

La dérive 3 est aussi fixée sur le bras rotatif, elle permet de maintenir les déflecteurs dans la position adéquate par rapport au vent dominant. Le frein 8 est monté sur un petit axe 14 solidaire du bras rotatif 7. The fin 3 is also fixed on the rotary arm, it keeps the deflectors in the correct position relative to the prevailing wind. The brake 8 is mounted on a small axis 14 secured to the rotary arm 7.

En position normale l'aileron 9 offre très peu de prise au vent et le patin il ne frotte pas sur la turbine 10. In normal position, the fin 9 offers very little wind resistance and the shoe does not rub on the turbine 10.

En tempête l'aileron 9 (réglé par des masselottes 15); soulève offre le maximum de surface au vent et le patin 11 est poussé avec force sur la partie supérieure de la turbine 10. Cette dernière est ralentie et le déflecteur 1 masque une plus grande partie des ailerons "en positif" et découvre même ceux en "négatif".  In storm fin 9 (adjusted by weights 15); raises offers the maximum surface area in the wind and the shoe 11 is pushed with force on the upper part of the turbine 10. The latter is slowed down and the deflector 1 masks a greater part of the fins "in positive" and even discovers those in " negative".
