Description

Wind generator of blades and kites.

Technical sector

The technique used is framed within the industrial applications of wind turbines; specifically in their blades, in order to optimize them and facilitate that they can act in situations of low wind, wind gusty, or strong wind.

Object of the invention

The present invention, as expressed in the statement of this specification refers to a generator wind that includes blades that revolve around the axis, which in its upper part is provided with a kite-like element, with the in order to face them in the wind during the rotary movement, to favor the rotation of the blades around the axis, facilitating in this way the rotation displacement of the blades, so which reduces the wind capacity needed to start or enhance the rotating movement of the blades around the axis thereby obtaining greater energy efficiency in conditions of little wind.

Background of the invention

Wind generators or wind turbines of state of the art are constituted by a mast in whose part upper is a head on which shovels are supported that they are located in a plane perpendicular to the ground, so that said blades can rotate on said plane. In addition the head is equipped with the corresponding means to transform the Rotational displacement of the blades in electrical energy. At state of the art no wind turbines are known in which the blades are joined together by an element as a Kite.

Description of the invention

The present invention proposes the development of a new wind generator comprising a mast (6) in whose part top is a head (11) in which the axis is hollow cone-shaped center (2), where the housings are housed blade rotation mechanisms, from - 45º to + 45º to be able to capture more or less wind and optimize the rotation of the group. This mechanism has several solutions that can be applied, proposing which is formed by a hydraulic with double arm and mounted on a pneumatic shock absorber, (3) each arm drives 2 blades and said pneumatic shock absorber allows some tolerance in case of gusty winds.

The axes of the blades are in the part Front axle or hollow cone and mechanisms at the rear to make maintenance and repair possible. It consists of four blades (4) with similar structure to those used by helicopters; flat throughout its length, that is, to Unlike the propellers normally used by mills conventional, and in its cross section are shaped like an eye elongated with a thicker area in its anterior part and a thinner one in its back. Articulated arms (5) that by markers (10) on the back of the kite or trailing edge and about pivot axes at the front of the kite or edge of attack, all located at the end of the blades to hold the kites and that give them the possibility of hunting more or less wind according to the orientation they have, the wind conditions and the Computer optimization of the electric generator. The kites (1) configured with a specific design mainly for offering a curved leading edge (8) and a straight trailing edge (9), with the purpose of being able to take advantage of all the wind possible without reaching touch the mast that supports the set in rotation. The kites (1) as well as the whole of the proposed invention will be preferably built in the following materials: fiber glass, carbon, balsa wood, keblar, epoxy, polyurethanes and filling foams. It would also be possible to use a structure multitubular as a hollow wing with some coating of materials, fiber or plastic type etc ... as a solution for Blades and kites. By the characteristics of the elements previously cited and the proposed structure of the own wind turbine the set of parts to be assembled can be reduced by 1/3 compared to the models currently used, but having the same alar surface or its size and consequently the same power capacity, it follows that at an equal size we will obtain a power 60% higher than the design of 3 propellers conventional.

The lightness of the set is due to the fact that parts are much smaller and the ability to "fly" from the kites that once started their rotation would generate a self-sustaining the set, thanks to its design Novel will gradually increase the speed of rotation, getting more revolutions and less weight.

The flexibility of the kite material allows the sides of it at the trailing edge to yield to the tension of the blades actuated by the blades, in this way the kite also adopts a somewhat deformed form in said trailing edge ends that help group rotation. All this has to be controlled by the computer supported by software specific that will be responsible for governing according to the values previously indicated. The leading edge of the blade it is much finer than the known propellers with what the Spin resistance is significantly reduced.

The blade and kite spinning system mounted on a hydraulic and pneumatic system as a sileblock eliminates vibrations and allows blades and comets to fall in conditions of strong gusts of wind with what is achieved that do not suffer the group and eliminates the possibility of breakage extending the useful life of the wind turbine assembly.

The manufacturing and transportation costs of pieces of the invention proposed here are minor in relation to known wind turbines since there is a reduction of the elements and parts that are used that in the case of propellers would be of about 1/3. Consequently, assembly also requires less effort and smaller cranes. A smaller visual impact, lowering the costs of the production process of the parts of the wind turbine as well as assembly and transport. It's more silent because there is no end of propeller that cuts the wind. The ability to fully knock down the set from -45º to 0º and + 45º (Less 45 Degrees, Zero Degrees and More 45 Degrees) allows us to capture all available wind, also zero capacity wind uptake in case of storm or hurricane and the possibility of braking the assembly in counter-rotation position to stop it in case of breakage or emergency, adopting kites a certain form with low power and maximum power.

We have eliminated the problem of losing lift at low revolutions as the blade has an edge of Very fine attack and the kite helps in the rotation of the group. For facilitate a better understanding of this specification and forming an integral part of it, a series of figures in which the object of the invention has been represented. The sizes, shapes, number of pieces, mechanisms and materials constitutive of the invention may be varied to adapt them to the advantages that can be derived from its concrete application always that this does not affect the essentiality of the invention. The terms in that this report has been written should always be taken Illustrative and not limiting.
