Abstract

The turbine has blades (1, 3, 4), where each blade is mounted on respective rotation axis (6) parallel to a general rotation axis (2). The blade is fixed on a support (8) by low wind and reacts under the effect of the wind, where the axle of the blade is liberated in case of more wind. The blade rests in a position facing the wind as a stickle arm, and not incident on an assembly of the turbine.

Description

Il existe déjà différentes formes de réalisations d'éolienne à axeThere already exist different forms of achievements of axis wind turbine

vertical. Elles sont destinées à transformer l'énergie du vent en énergie mécanique afin d'entraîner une pompe, une génératrice électrique, par exemple. La présente invention concerne les pales de l'éolienne, organe principal pour la 5 transformation de l'énergie du vent en un mouvement de rotation. La forme utilisée dans la présente invention a déjà été réalisée il y a plusieurs années. En forme d'auge, en matériau composite, elle a l'avantage de se déformer sous la force du vent et ainsi sa réaction a pour résultat la mise en rotation du système sur laquelle elle est fixée.  vertical. They are intended to transform wind energy into mechanical energy to drive a pump, an electric generator, for example. The present invention relates to wind turbine blades, the main member for converting wind energy into rotational motion. The form used in the present invention has already been realized several years ago. In the form of trough, made of composite material, it has the advantage of being deformed under the force of the wind and thus its reaction results in the rotation of the system on which it is fixed.

10 Le système en forme de roue à aubes ainsi obtenu par la multiplication des pales autour d'un axe, présente une surface très intéressante au vent et ainsi permet un bon rendement par vent faible. Par grand vent le comportement des pales souples ne suffit pas à freiner l'éolienne. Les effets dus au vent fort sont préjudiciables à tous les éléments constituant cette éolienne.The paddlewheel system thus obtained by multiplying the blades about an axis, has a very attractive surface to the wind and thus allows a good performance in low wind. In high wind the behavior of the soft blades is not enough to brake the wind turbine. The effects due to strong wind are detrimental to all components of this wind turbine.

15 La présente invention permet de remédier à cet inconvénient. Suivant la première revendication les pales sont fixées sur un système qui peut pivoter autour d'un axe parallèle à l'axe de rotation principal. La possibilité de rotation de la pale autour de son propre axe est provoqué par le déblocage ou débrayage automatique et mécanique de son axe obtenu sous l'influence de la vitesse du vent sur l'ensemble 20 général de l'éolienne. Cette influence peut être relevée à l'aide d'un anémomètre avec système de transformation du signal obtenu, ou une masse en déplacement sous l'effet de la force centrifuge ou de type mécanique en déplacement dont le signal ou le mouvement peut activer un système électrique, hydraulique, ou mécanique libérant ainsi l'axe de la pale lui permettant de tourner autour d'elle même. La pales 25 débloquées se trouvent folles autour de leur propres axes et ainsi se placent toujours face au vent en position de drapeau. La présente invention permet donc de maîtriser la vitesse de rotation de cette éolienne en débrayant des pales en libérant leurs axes. En effet il est possible de libérer les unes après les autres chaque pale obtenant ainsi la diminution du nombre 30 de pales réactives présentées au vent. Suivant le choix de réalisation de l'éolienne par très grand vent il ne pourrait rester que deux pales actives. Les autres pales sont en position de drapeau. Le système de déblocage de l'axe de chaque pale restant toujours actif permettra le rebloquage de chaque axe indépendamment dès la diminution de la 35 vitesse de rotation de l'éolienne. La forme des pales peut être différente sur une même éolienne. En effet des pales de forme appropriée peuvent être maintenant prévues pour réagir par petit vent car elle seront libérées et se placeront en drapeau ou reviendront en phase de réaction dès que le vent se modifiera en'vitesse.The present invention overcomes this disadvantage. According to the first claim the blades are fixed on a system that can pivot about an axis parallel to the main axis of rotation. The possibility of rotation of the blade around its own axis is caused by the automatic unlocking or mechanical disengagement of its axis obtained under the influence of the wind speed on the general assembly of the wind turbine. This influence can be detected by means of an anemometer with a signal transformation system obtained, or a moving mass under the effect of centrifugal force or mechanical displacement type whose signal or movement can activate a system electrical, hydraulic, or mechanical and releasing the axis of the blade allowing it to rotate around itself. The unblocked blades are crazy about their own axes and thus always face the wind in the flag position. The present invention thus makes it possible to control the speed of rotation of this wind turbine by disengaging the blades by releasing their axes. Indeed it is possible to release one after the other each blade thus obtaining the decrease in the number of reactive blades presented to the wind. Depending on the choice of realization of the wind turbine in very high wind there could be only two active blades. The other blades are in the flag position. The unlocking system of the axis of each blade remaining active will enable the re-locking of each axis independently as soon as the speed of rotation of the wind turbine decreases. The shape of the blades can be different on the same wind turbine. Indeed blades of appropriate shape can now be provided to react in small wind because they will be released and will be flagged or will return to the reaction phase as soon as the wind will change in speed.

40 Suivant les modes particuliers de fabrication, le nombre, la forme de pales, le nombre d'étages de supports pales n'ont pas d'importance. Les dessins annexés illustrent l'invention : La Figure 1 représente une forme particulière d'éolienne. Nous pouvons y voir au moins deux formes de pale. Les pales (1) les plus éloignées de l'axe de rotation ( 45 2 ) sont plus larges et l'aube est plus prononcée que les pales ( 4 ) présentant ainsi plus de surface et de piège pour un vent faible. La partie (10 ) sert à la fois de support et de local technique. La figure 2 représente l'éolienne vue de dessus. La pale (3) est représentée face au vent ( 5 ) en drapeau tournant donc autour de son propre axe de rotation ( 6 ) quand 50 l'éolienne tourne autour de son axe ( 2 ). ' La-figure 3 représente un bras support de pale, en vue de dessus. La pale (1) est bloquée en rotation et nous remarquons la déformation (.9 ) au vent ( 5 ) de la pale créant ainsi un mouvement de rotation (7) autour de l'axe ( 2 ) de l'éolienne. La figure 4 représente la même pale (1) libérée de son système de blocage en rotation tournant ainsi autour de son axe (6 ) ne présentant aucune réaction au vent ( 5 ). L'éolienne tourne autour de son axe (2 ) entraînée par d'autres pales non représentées sur ces figures 3 et 4. En même temps la pale (1) tourne autour de son axe (6) et donc toujours en position drapeau face au vent ( 5 ). La figure 5 représente un exemple de réalisation d'une éolienne à deux étages dont la partie haute est destinée aux pales plus larges réagissant ainsi au vent. faible. Ainsi le support de pales (8) peut être de plusieurs niveaux et de dimensions différentes afin de mieux atteindre le meilleur rapport comme par exemple hauteur au sol par rapport au.diamètre des différents. étages ou par rapport à la position et dimensions des pales afin d'obtenir le meilleur rendement en fonction de la situation topographique du lieu d'implantation. La figure 6 représente la même éolienne mais dont toutes les pales (3 ) destinées à la réaction sous vent faible sont çlébrayées et se trouvent en conséquence toutes en position drapeau. Les pales (4 ) sont encore fixes et réagissent sous vent plus fort. Elles se 20 débrayeront si besoin par vent encore plus ffi.According to the particular modes of manufacture, the number, the shape of the blades, the number of stages of blade supports do not matter. The attached drawings illustrate the invention: FIG. 1 represents a particular form of wind turbine. We can see at least two shapes of blades. The blades (1) furthest from the axis of rotation (45 2) are wider and the blade is more pronounced than the blades (4) thus presenting more surface and trap for a weak wind. Part (10) serves both as support and as a technical room. Figure 2 shows the wind turbine viewed from above. The blade (3) is shown facing the wind (5) in a flag thus rotating around its own axis of rotation (6) when 50 the wind turbine rotates about its axis (2). Figure 3 shows a blade support arm in plan view. The blade (1) is locked in rotation and we notice the deformation (.9) wind (5) of the blade thus creating a rotational movement (7) around the axis (2) of the wind turbine. FIG. 4 represents the same blade (1) released from its rotation locking system thus rotating about its axis (6) exhibiting no reaction to the wind (5). The wind turbine rotates about its axis (2) driven by other blades not shown in these figures 3 and 4. At the same time the blade (1) rotates about its axis (6) and therefore always in the flag position facing the wind (5). FIG. 5 represents an exemplary embodiment of a two-stage wind turbine whose upper part is intended for the wider blades thus reacting to the wind. low. Thus the blade support (8) can be of several levels and of different dimensions in order to better achieve the best ratio such as ground height compared to.diameter of different. levels or relative to the position and dimensions of the blades to obtain the best performance according to the topographical situation of the location. Figure 6 shows the same wind turbine but all blades (3) for the reaction in low wind are released and are all accordingly flag position. The blades (4) are still fixed and react under stronger wind. They will disengage if necessary by even more ffi wind.
