Abstract

The device has a rotor (1) with horizontal axle, where rotor has blades with selected and oriented bird feathers (2) associated to a brushless generator (3). The generator has a brushless motor that functions in inverse and delivers alternative voltage windings on outlet. The generator is connected to a continuous voltage regenerator mounting permitting production of light by high density LED (10).

Description

L'objet de l'invention est un petit aérogénérateur d'une puissance maximale de quelques watts, de conception très simple et de coût réduit. Il s'agit d'une micro-éolienne ultra sensible et ultra légère. Il comporte un rotor à axe horizontal, une nacelle contenant la génératrice et l'électronique, un gouvernail et un mât vertical. L'énergie produite est entièrement utilisée à bord de la nacelle, soit pour produire de la lumière avec des diodes électro-luminescentes (DEL) de très haute luminosité, soit pour recharger un accumulateur amovible, soit pour d'autres applications . The object of the invention is a small wind turbine with a maximum power of a few watts, very simple design and low cost. It is a micro-wind turbine ultra sensitive and ultra light. It includes a horizontal axis rotor, a nacelle containing the generator and electronics, a rudder and a vertical mast. The energy produced is entirely used on board the nacelle, either to produce light with very high-brightness electroluminescent diodes (LEDs), to recharge a removable battery, or for other applications.

L'utilisation peut en être variée, sous forme de balise lumineuse fixe, sous forme de balise transportée sur un vélo ou un sac à dos (la vitesse de la marche étant déjà suffisante pour démarrer la génératrice ), ou sous forme d'objet ludique se maniant facilement à l'aide d'un manche. The use can be varied, in the form of a fixed light beacon, in the form of a beacon carried on a bike or a backpack (the speed of walking is already sufficient to start the generator), or as a play object easily handled with a handle.

Pour la description des différentes parties, on pourra se référer aux figures 1,2,3. Le rotor est constitué d'un bloc (1) directement collé sur le boîtier de la génératrice (3), sur lequel sont insérées des plumes d'oiseau (2) de forme et d'orientation adéquates. For the description of the different parts, reference may be made to FIGS. The rotor consists of a block (1) directly adhered to the housing of the generator (3), on which are inserted bird feathers (2) of adequate shape and orientation.

Le nombre ( deux au minimum ) et la taille des plumes est déterminé en fonction de la puissance de la génératrice choisie pour l'application. Une hélice en plastique telle que celles utilisées en aéromodélisme peut remplacer les plumes mais présente un comportement différent : à taille égale, elle tournera plus vite et donnera plus d'énergie, mais il lui faut plus de vitesse de vent pour démarrer. Elle sera montée avec le côté concave des pales du côté du vent pour plus d'efficacité. La génératrice est un moteur brushless du type de ceux utilisés pour les ventilateurs de PC, qui a été inversé en ce que la tension alternative produite est récupérée directement à la sortie des enroulements. Des moteurs pas à pas inversés peuvent fournir une énergie plus importante, mais ils nécessitent un couple de démarrage plus élevé et donc ne fonctionnent qu'avec des plumes en nombre relativement élevé. L'électronique comporte un circuit régénérateur de tension continue, un limiteur de courant pour les diodes DEL et éventuellement un contrôleur de charge pour accumulateurs. La nacelle est composée d'une seule pièce taillée et percée dans la masse. Sa matière est préférentiellement un bois imputrescible. The number (at least two) and the size of the pens is determined by the power of the generator chosen for the application. A plastic propeller such as those used in model aircraft can replace the feathers but has a different behavior: at equal size, it will rotate faster and give more energy, but it needs more wind speed to start. It will be mounted with the concave side of the blades on the windward side for more efficiency. The generator is a brushless motor of the type used for PC fans, which has been inverted in that the AC voltage produced is recovered directly at the output of the windings. Inverted stepper motors can provide higher energy, but they require a higher starting torque and therefore only work with relatively large numbers of feathers. The electronics comprise a DC voltage regenerator circuit, a current limiter for the LED diodes and possibly a charge controller for accumulators. The nacelle is composed of a single piece cut and pierced in the mass. Its material is preferably an imputrescible wood.

Les diodes DEL (10) sont montées à l'extérieur soit à ras du bloc de la nacelle, soit à l'extrémité d'un tube (11) dont la pliure peut être modifiée à volonté par l'utilisateur, de façon à pouvoir orienter le flux lumineux dans n'importe quelle direction. The LED diodes (10) are mounted outside either flush with the block of the nacelle or at the end of a tube (11) whose fold can be modified at will by the user, so as to be able to orient the luminous flux in any direction.

Le gouvernail est composé d'une grande plume, ou d'une association de quelques plumes de forme plane, ou encore d'une fine plaque de bois ou de plastique. Le mât ( ou le manche pour la version ludique) est en bois. Le pivot permettant la rotation de la nacelle est une tige filetée vissée dans le 10 mât, elle traverse librement la base de la nacelle et est retenue à l'intérieur de celle-ci par un écrou dit de sécurité. L'ensemble a fait l'objet d'une étude de design, ce qui en fait un objet insolite, beau à regarder et à voir fonctionner tant mécaniquement que visuellement. La lumière des diodes est visible à plusieurs 15 centaines de mètres la nuit. De plus, dans la version ludique, lors de la rotation de la nacelle, le frottement de la tige filetée sur le bois déclenche un bruit stridulant rappelant le chant d'un oiseau. The rudder is composed of a large feather, or a combination of some flat-shaped feathers, or a thin plate of wood or plastic. The mast (or the handle for the playful version) is made of wood. The pivot allowing the rotation of the nacelle is a threaded rod screwed into the mast, it passes freely through the base of the nacelle and is retained inside thereof by a nut said security. The set was the subject of a design study, making it an unusual object, beautiful to look at and see function both mechanically and visually. The light of the diodes is visible at several hundred meters at night. In addition, in the playful version, during the rotation of the nacelle, the friction of the threaded rod on the wood triggers a stridulant sound reminiscent of the song of a bird.
