Abstract

A primary blade (2) is oriented so that its rotation forces air through an auxiliary turbine. Wind flow (1) drives the primary blade (2) at a speed which is low for electric generators. The auxiliary turbine (6) is moved through the air at the velocity of the tip of the primary blade, resulting in a high shaft speed in the auxiliary turbine, allowing electricity generation with smaller ratios between the turbine and the generator. Electricity can also be generated by the auxiliary turbine (6) if the primary blade (2) is rotated by, for example, an electric motor when there is no wind.

Description

La présente invention concerne les dispositifs destinés à capter lténergie cinétique d'un fluide en écoulement tel que le vent par exemple et ceçi en vu de transformer cette énergie recueillie sous forme d'autres énergies: de type domestique; électricité par exemple. The present invention relates to devices intended to capture the kinetic energy of a flowing fluid such as wind for example and this in view of transforming this energy collected in the form of other energies: of the domestic type; electricity for example.

L'invention présente, a pour but de réaliser un ensemble capteur, ou le dispositif destiné à transformer lténergie mécanique recueillie; Alternateur ou dynamo dans le cas de production d'électricité, soit entrainé par un second dispositif capteur, tournant plus rapidement que le premier du fait d'un écoulement de fluide, de vitesse plus élevée, cet écoulement étant crée artificiellement pour ainsi dire. The purpose of the present invention is to produce a sensor assembly, or the device intended to transform the mechanical energy collected; Alternator or dynamo in the case of electricity production, either driven by a second sensor device, rotating faster than the first due to a flow of fluid, of higher speed, this flow being created artificially so to speak.

Le fait que le second capteur ait une vitesse de rotation plus importante que celle du premier capteur, permet ainsi de réduire, voir supprimer les organes multiplicateurs, entre le second capteur et le dispositif transformateur de lténergie recueillie. The fact that the second sensor has a higher speed of rotation than that of the first sensor, thus makes it possible to reduce, or even eliminate the multiplier members, between the second sensor and the device transforming the energy collected.

Selon une réalisation de l'invention, faite dans une optique de construction rationnelle par la suite, le type de capteur retenu, est celui ayant un rapport U/V supérieur à 1, U étant la vitesse de déplacement la plus importante des aubes motrices du capteur, V étant la vitesse d'écoulement du fluide entrainant l'ensemble. According to one embodiment of the invention, made with a view to rational construction thereafter, the type of sensor selected is that having a U / V ratio greater than 1, U being the most significant speed of movement of the driving vanes of the sensor, V being the flow speed of the fluid driving the assembly.

Conformement à l'invention, sur le premier capteur décrit çi dessus, est disposé solidairement un second ensemble capteur, étudié et réalisé afin d'entrainer un dispositif quelconque, transformateur d'énergie, tel qu'un alternateur par exemple. Ainsi réalisée, l'invention fonctionne de la manière suivante. Le fluide en écoulement par son énergie cinétique entraine le premier capteur par l'åntermédiaire de ces aubes motrices. In accordance with the invention, on the first sensor described above, there is arranged a second sensor assembly, studied and produced in order to drive any device, energy transformer, such as an alternator for example. Thus produced, the invention operates in the following manner. The flowing fluid by its kinetic energy drives the first sensor through these motor vanes.

L' énergie mécanique ainsi captée, se présente ici sous la forme d'un mouvement ou déplacement résultant de la rotation des aubes motrices, et par la même du dispositif capteur dans son ensemble. Le second ensemble capteur d'énergie cinétique du fait de sa fixation solidaire sur le premier ensemble capteur, entre lui aussi en mouvement, se déplaçant ainsi dans le fluide ambiant. Dans ce cas, lténergie cinétique captée par le second dispositif, est due au déplacement m8me de ce dernier par rapport au fluide ambiant, apparemment immobile. The mechanical energy thus captured, appears here in the form of a movement or displacement resulting from the rotation of the driving vanes, and by the same of the sensor device as a whole. The second kinetic energy sensor assembly due to its integral attachment to the first sensor assembly, also in motion, thus moving in the ambient fluid. In this case, the kinetic energy captured by the second device is due to the same movement of the latter relative to the ambient fluid, apparently immobile.

Le dessin (fig. 1) annexé, illustre à titre d'exemple un mode de réalisation du dispositif conforme à la pressente invention. Tel qu'il est représenté; le dispositif est entrainé par le fluide 1 et 1'. Le capteur 2 accomplit un mouvement de déplacement 3, ici en l'occurence un mouvement de rotation, et entraine du fait de la fixation solidaire 4 un second dispositif capteur 5 entrainant un dispositif transformateur d'énergie 6.  The appended drawing (FIG. 1) illustrates by way of example an embodiment of the device according to the present invention. As shown; the device is driven by the fluid 1 and 1 '. The sensor 2 performs a movement of displacement 3, here in this case a movement of rotation, and causes, due to the integral fixing 4, a second sensor device 5 driving an energy transformer device 6.

Selon une réalisation de l'invention, dans une optique de construction rationnelle par la suite, le premier capteur sous l'action du fluide en écoulement, accomplit son mouvement ou déplacement, à une vitesse multiple de celle de l'écoulement du fluide. Ainsi le rapport U/V est supérieur à 1. Toujours dans la même optique de construction, le second capteur d'énergie, dans une réalisation particulière de l'invention, est disposé solidairement à l'extrémité du premier capteur accomplissant la vitesse de déplacement U la plus importante. According to one embodiment of the invention, with a view to rational construction thereafter, the first sensor under the action of the flowing fluid, accomplishes its movement or displacement, at a speed multiple of that of the flow of the fluid. Thus the U / V ratio is greater than 1. Still in the same construction perspective, the second energy sensor, in a particular embodiment of the invention, is disposed integrally at the end of the first sensor achieving the speed of movement U the most important.

Dans une autre réalisation de l'invention, le ou les sens de rotation du second capteur ou ensemble capteur, sont définis afin de permettre une amélioration du rendement de l'ensemble, en faisant converger le fluide en écoulement, directement sur le premier capteur, tout en permettant sa divergence à l'arrière de ce dernier. Le dessin (fig. 2) annexé illustre à titre d'exemple cette disposition particulière. Le second ensemble de capteur 5, par son ou ses sens propres de rotation 7, provoque une convergence 8 du fluide en écoulement directement vers le capteur 2, et une divergence 9 du fluide en écoulement à l'arrière. In another embodiment of the invention, the direction or directions of rotation of the second sensor or sensor assembly are defined in order to allow an improvement in the efficiency of the assembly, by making the flowing fluid converge, directly on the first sensor, while allowing its divergence at the back of the latter. The accompanying drawing (fig. 2) illustrates this particular arrangement by way of example. The second sensor assembly 5, by its own direction or directions of rotation 7, causes a convergence 8 of the flowing fluid directly towards the sensor 2, and a divergence 9 of the flowing fluid at the rear.

La présente invention s'applique principalement à la construction de capteurs éoliens, toutefois une variante intéressante pourrait être appliquer à la captation des courants marins par exemple.  The present invention applies mainly to the construction of wind sensors, however an interesting variant could be applied to the capture of sea currents for example.
