Description
1 La présente invention concerne un dispositif aérodynamique à axe horizontal pour la transformation de l'énergie produite naturellement par le vent en énergie électrique.The present invention relates to a horizontal axis aerodynamic device for transforming the energy naturally produced by the wind into electrical energy.
Les éoliennes à axes horizontales représentent essentiellement des coûts de maintenance très élevés de par leur conception. Quant aux éoliennes à axe verticale, elles génèrent certes des coûts de maintenance moins élevés mais en revanche, elles sont moins performantes du fait qu'elles ont l'inconvénient majeur d'avoir d'importantes déperditions énergétiques due aux frottements plus importants pour maintenir leur équilibre en fonctionnement. Le but de l'invention est de remédier à ces inconvénients en proposant un concept d'éolienne étant un juste compromis des deux, c'est-15 à-dire une éolienne à haut rendement d'où une éolienne à axe horizontal, et à maintenance faible, d'où des frottements inexistants. De plus, cette éolienne de par son concept est moins bruyante pour les raisons évoquées. Cette éolienne de forme cylindrique est composée d'une partie fixe à l'intérieur de laquelle tourne en rotation sans contact physique une partie 20 mobile. Cette éolienne à énergie renouvelable à axe horizontal montée sur une axe rotulé (5), comporte une nacelle externe (1) et une partie centrale (2) appelée bulbe qui équipé d'ailerons (7) est capable de toujours se 25 positionner face au vent, permettant à ce dernier de s'engouffrer dans le couloir défini par la nacelle et le bulbe autour duquel est mis en rotation sous l'effet du vent une partie mobile appelée rotor. La nacelle externe (1) et le bulbe (2) sont tout deux assemblés concentriquement par l'intermédiaire d'une platine Avant ajourée (3) pour 30 laisser entrer le vent, et d'une seconde platine Arrière ajourée (4) pour laisser sortir le vent permettant d'avoir un alignement géométrique et de 3034818 2 garantir une certaine robustesse de l'ensemble. Ces platines (3) et (4) ajourées sont conçues de manière à freiner au minimum le vent venant s'engouffrer par l'avant et s'échapper par l'arrière dans le couloir se situant entre la nacelle et le bulbe où le vent prend son accélération.Wind turbines with horizontal axes essentially represent very high maintenance costs by their design. As for vertical axis wind turbines, they certainly generate lower maintenance costs but, on the other hand, they are less efficient because they have the major disadvantage of having significant energy losses due to greater friction to maintain their performance. balance in operation. The object of the invention is to remedy these drawbacks by proposing a wind turbine concept being a fair compromise of the two, that is to say a high efficiency wind turbine from which a wind turbine with a horizontal axis, and low maintenance, resulting in non-existent friction. In addition, this wind turbine by its concept is less noisy for the reasons mentioned. This cylindrical wind turbine is composed of a fixed part inside which rotates in rotation without physical contact a moving part. This renewable energy wind turbine with horizontal axis mounted on a rotational axis (5), comprises an external nacelle (1) and a central part (2) called bulb which equipped with fins (7) is able to always position itself in front of the wind, allowing the latter to rush into the corridor defined by the nacelle and the bulb around which is rotated under the effect of the wind a mobile part called rotor. The outer nacelle (1) and the bulb (2) are both assembled concentrically via a perforated front plate (3) to let the wind in, and a second openwork backplate (4) to let the wind take out the wind to have a geometric alignment and 3034818 2 to ensure a certain robustness of the whole. These plates (3) and (4) perforated are designed to minimize the wind coming rush from the front and escape from behind in the corridor between the basket and the bulb where the wind takes its acceleration.
5 Cet ensemble compact monté sur l'axe vertical (5) équipé d'une rotule (6) permet d'obtenir une rotation libre sur 360° autour de cet axe ainsi qu'une inclinaison horizontal de ± 30°autour de ce même axe. Le bulbe (2) équipé en partie arrière externe de ses ailerons (7) oriente cet ensemble compact face au vent telle une girouette permettant 10 de ce fait de capter les meilleurs vents du moment lors du fonctionnement de l'éolienne. Le rotor est constitué au moins de 8 pales (11) à géométrie évolutives 3D fixées en partie basse sur une couronne circulaire (9) et en partie haute sur deux demi-coquilles circulaires (12) et (13) équipées d'aimants (15) et (16), A son tour, le bulbe (2) sur son diamètre extérieur et la couronne circulaire (9) du rotor sont équipés d'un nombre différent d'aimants (8) et (10) évitant l'existence d'une position « repos stable » montés en opposition polaire afin de garantir leur positionnement radial l'un par rapport à l'autre sans contact sous l'effet de la sustentation magnétique produite, ne générant ainsi aucun frottement, (Figures 2 et 3) La nacelle (1) et la platine arrière (4) sont équipées d'un nombre différent d'aimants (17) et (18) évitant l'existence d'une position « repos stable » montés judicieusement en polarité identique à celles présentent sur le rotor en partie haute afin de lui garantir un positionnement axial sans contact sous l'effet de la sustentation magnétique produite, ne générant ainsi aucun frottement, 3034818 3 Les deux demi-coquilles (12) et (13) composant une partie du rotor sont équipées d'un nombre différent d'aimants (15) et (16) évitant l'existence d'une position « repos stable » montés judicieusement en polarité identique à celles présentent sur la nacelle (1) et la platine arrière (4) du stator afin 5 de garantir au rotor un positionnement axial sans contact sous l'effet de la sustentation magnétique produite, ne générant ainsi aucun frottement, Pour finir, la nacelle (1) est munie sur sa périphérie intérieure d'autant de 10 bobinages (14) que d'aimants du rotor, Le vent s'engouffrant dans le couloir défini par l'intérieur de la nacelle (1) et l'extérieur du bulbe (2) est équipé d'au moins 4 ailerons « bec de canard » 15 (19) qui permettent d'accélérer le vent pour lui conférer une vitesse mettant en rotation le rotor. Lorsque le vent devient trop important, la sustentation magnétique axiale générée par les aimants (15), (16), (17) et (18) n'étant plus suffisante positionne le rotor en contact sur la platine arrière (4) arrêtant ainsi ce 20 dernier en rotation, Lors de la mise en rotation sans contact du rotor, les aimants (15) et (16) lors de leur passage devant chaque bobine (14) produisent un champ magnétique générant un courant électrique, 25 L'éolienne à énergie renouvelable est réalisée dans des matériaux résistants aux intempéries maritimes.This compact assembly mounted on the vertical axis (5) equipped with a ball joint (6) makes it possible to obtain a 360 ° free rotation about this axis as well as a horizontal inclination of ± 30 ° around this same axis. . The bulb (2) equipped in the outer rear part of its fins (7) directs this compact assembly against the wind such a wind vane 10 thereby capturing the best winds of the moment during operation of the wind turbine. The rotor consists of at least 8 blades (11) with 3D evolutionary geometry fixed at the bottom on a circular ring (9) and at the top on two circular half-shells (12) and (13) equipped with magnets (15). ) and (16), in turn, the bulb (2) on its outer diameter and the circular ring (9) of the rotor are equipped with a different number of magnets (8) and (10) avoiding the existence of a "stable rest" position mounted in polar opposition in order to guarantee their radial positioning relative to each other without contact under the effect of the magnetic levitation produced, thus generating no friction, (FIGS. 2 and 3) The nacelle (1) and the rear plate (4) are equipped with a different number of magnets (17) and (18) avoiding the existence of a "stable rest" position judiciously mounted in the same polarity as those present on the rotor in the upper part to guarantee an axial positioning without contact under the effect of the magnetic levitation produced, thus generating no friction, 3034818 3 The two half-shells (12) and (13) forming part of the rotor are equipped with a different number of magnets (15) and (16) avoiding the existence of a "stable rest" position judiciously mounted in the same polarity as those present on the platform (1) and the rear plate (4) of the stator in order to guarantee the rotor axial positioning without contact under the effect of the lift generated magnetic, thus generating no friction, Finally, the nacelle (1) is provided on its inner periphery with as many windings (14) as magnets of the rotor, the wind rushing in the corridor defined by the the interior of the nacelle (1) and the outside of the bulb (2) is equipped with at least 4 "duckbill" fins (19) which make it possible to accelerate the wind to give it a speed which rotates the rotor. When the wind becomes too great, the axial magnetic levitation generated by the magnets (15), (16), (17) and (18) being no longer sufficient positions the rotor in contact on the rear plate (4) thus stopping this Lastly in rotation, when the rotor is rotated without contact, the magnets (15) and (16) as they pass each coil (14) produce a magnetic field generating an electric current. renewable is made of materials resistant to marine weather.
