Abstract

The wind turbine speed is regulated by mounting the vertical shaft in a mounting which allows the wind turbine to tilt so as to alter the angle of attack of the wind and so reduce the speed of the turbine. A counter weight fitted to the vertical shaft below its multi-axis pivot counters the forces exerted by the wind. The turbine tilts from the vertical position about an axle which passes through the turbine shaft and is fixed to an outer ring by pins which allow tilting of the axle about which the shaft tilts. The outer ring has an external toothed wheel attached from which generator drive may be taken, and this ring runs on bearings about a mounting to the support frame.

Description

DESCRIPTION
Système de régulation de sécurité pour éolienne à axe vertical
L'objet de la présente invention est un système de régulation et aussi de séc@- rite adaptable à toute éolienne à are vertical. DESCRIPTION
Safety control system for vertical axis wind turbines
The object of the present invention is a regulation and also safety system adaptable to any vertical wind turbine.

L'objet de la présente invention est en l'occurence de créer, par tous moyens, un axe d'articulation au niveau du pied de l'éolienne permettant au sommet de eelle-ci de se déplacer afin de réduire les contraintes et la prise au vent.The object of the present invention is in this case to create, by all means, a hinge pin at the foot of the wind turbine allowing the top of it to move in order to reduce the stresses and the grip in the wind.

Cette articulation peut-être munie d'un dispositif quelconque assurant la prise du mouvement (par exemple : cardan) qui entraine lui-même un dispositif assurant la transmission du mouvement.This joint may be provided with any device ensuring the taking of the movement (for example: gimbal) which itself drives a device ensuring the transmission of the movement.

Le secteur de la technique sur lequel porte principalement la présente invention est la récupération d'énergie fournie par le vent en vue de la transformation énergie électrique ou mécanique. Actuellement, certains dispositifs sont connus mais ils sont souvent complexes, fragiles, donc plus coûteux. D'autre part, la simplicité de ce dispoSitif, objet de la présente invention, le rend fiable et lui permet de stadapter à toute éolienne à axe vertical tout en lui gardant un prix de revient raisonnable.The sector of the technique to which the present invention mainly relates is the recovery of energy supplied by the wind with a view to transforming electrical or mechanical energy. Currently, some devices are known, but they are often complex, fragile, and therefore more expensive. On the other hand, the simplicity of this device, object of the present invention, makes it reliable and allows it to stadapter to any wind turbine with vertical axis while keeping it a reasonable cost price.

La présente invention lie en rotation l'axe vertical de l'éolienne. Elle lui permet d'osciller dans tbus les plans afin de réduire l'axe de l'attaque du vent sur les palles de l'éolienne. Elle joue donc un double rôle : d'abord, de régulateur de vitesse afin de ne pas endommager les appareils de production d'énergie, ou l'éolienne, ce qui remplace le variateur de pas des éoliennes classiques. Ensuite, les efforts au niveau le plus charge de l'axe sont réduits
Il s'agit donc d'un système de régulation et de sécurité
Pour comprendre le mécanisme de fonctionnement de ce système de régulation et de sécurité, objet de la présente invention, on se reportera aux dessins qui figurent sur la planche unique annexée.The present invention rotates the vertical axis of the wind turbine. It allows it to oscillate in tbus the plans in order to reduce the axis of the attack of the wind on the blades of the wind turbine. It therefore plays a double role: first, as a speed regulator so as not to damage the energy-producing devices, or the wind turbine, which replaces the step variator of conventional wind turbines. Then the forces at the most loaded level of the axis are reduced
It is therefore a regulatory and safety system
To understand the operating mechanism of this regulation and security system, object of the present invention, reference will be made to the drawings which appear on the attached single sheet.

Exemple de réalisation :
L'axe de l'éolienne 7 est lié en rotation et en translation à la couronne I par l'intermédiaire de l'axe 8. Cependant l'axe 7 peut osciller autour de 8 suivant l'axe ZZ' du repère orthonormé (O I J K) d'un angle de #
La couronne I est liée en rotation et en translation par l'intermédiaire des deux axes 2. Mais, la couronne 1 peut elle aussi osciller autour des axes 2.Example of realization:
The axis of the wind turbine 7 is linked in rotation and in translation to the crown I via the axis 8. However, the axis 7 can oscillate around 8 along the axis ZZ 'of the orthonormal reference frame (OIJK ) at an angle of #
The crown I is linked in rotation and in translation by means of the two axes 2. However, the crown 1 can also oscillate around the axes 2.

suivant l'axe XX' du repère orthonormé (O I J K) d'un angle de - la couronne 3 qui lie la couronne T en translation et en rotation est lice à la bague extérieure de la couronne à billes à denture extérieure droite !. ta bague intérieure 4' de la couronne à billes est solidaire de la. pièce 5.along the axis XX 'of the orthonormal coordinate system (O I J K) by an angle of - the crown 3 which links the crown T in translation and in rotation is linked to the outer ring of the ball crown with straight external teeth !. your inner ring 4 'of the ball crown is integral with the. Exhibit 5.

Cette pièce 5 assure la liaison complète de la pièce 4' au chassis 5.This part 5 ensures the complete connection of the part 4 'to the chassis 5.

Elle limite également l'angle dtinclinaison de l'axe de l'éolienne. It also limits the angle of inclination of the axis of the wind turbine.

Principe de fonctionnement :
l'arbre de l'éolienne entraine en rotation la pièce I qui entraine à son tour
la pièce 3 et de ce fait 7a pièce '- (rotation de l'arbre de l'éolienne suivant
l'axe YY').Principle of operation:
the wind turbine shaft rotates the part I which in turn drives
piece 3 and therefore 7a piece '- (rotation of the wind turbine shaft following
axis YY ').

- Si une force est exercée suivant l'axe XX' l'éolienne s'inclinera suivant
l'axe ZZ'.- If a force is exerted along the XX 'axis, the wind turbine will tilt according to
the axis ZZ '.

- Si une force est exercée suivant l'axe ZZt l'éolienne s'inclinera suivant
l'axe YY'.- If a force is exerted along the ZZt axis the wind turbine will tilt according to
the YY 'axis.

les efforts dus au vent sont équilibrés par un contrepoids solidaire de l'axe (P) ou tout autre moyen.wind forces are balanced by a counterweight secured to the axis (P) or any other means.

Les possibilités d'applications industrielles sont nombreuses : ltapplication principale réside dans la transformation de l'énergie fournie par le vent en une énergie électrique The possibilities of industrial applications are numerous: the main application resides in the transformation of the energy supplied by the wind into an electrical energy
