Definitions

  • the technique used falls 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, gusty wind, or strong wind.
  • the present invention refers to a wind generator that includes blades that revolve around the axis, which in its upper part are provided with a kite-like element, with the in order to face them in the wind during the rotary displacement, to favor the rotation of the blades around the axis, thus facilitating the displacement of rotation of the blades, so that the wind capacity necessary to initiate or enhance the rotational movement is reduced of the blades around the axis, thereby obtaining greater energy efficiency in low wind conditions.
  • the wind generators or wind turbines of the state of the art are constituted by a mast in whose upper part there is a head in which blades are supported that are located in a plane perpendicular to the ground, so that said blades can rotate on said plane.
  • the head is equipped with the corresponding means that allow
  • the present invention proposes the development of a new wind generator comprising a mast (6) in whose upper part a head (11) is arranged in which the hollow cone-shaped central axis (2) is located, where the mechanisms are housed of rotation of the blades, from - 45 ° to + 45 ° 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 that which is formed by a double-arm hydraulic 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 front of the shaft or hollow cone and the mechanisms in the rear to enable maintenance and repair. It consists of four blades (4) with similar structure to those used by helicopters; flat in its entire length, that is, unlike the propellers normally used by conventional mills, and in its cross section they have an elongated eye shape with a thicker area in its anterior part and a thinner one in its posterior part.
  • Articulated arms (5) that by means of markers (10) on the back of the kite or trailing edge and pivoting axes on the front of the kite or leading edge, 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 optimization of the computer 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), in order to take advantage of all the possible wind without touching the mast that supports the set in rotation.
  • kites (1) as well as the set of the proposed invention will preferably be constructed in the following materials: fiberglass, carbon, balsa wood, keblar, epoxy, polyurethanes and filler foams. It would also be possible to use a multitubular structure as a hollow wing with some coating of materials, fiber or plastic type etc. as a solution for the blades and kites. Due to the characteristics of the aforementioned elements and the proposed structure of the wind turbine itself, 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, from this it follows that at an equal size we will obtain a power 60% higher than the conventional 3-helices design.
  • the lightness of the set is due to the fact that the parts are much smaller and the ability to "fly" from the kites that once started their rotation would generate a self-sustaining of the set, thanks to its innovative design will increase the speed of rotation of Gradually, getting more revolutions and less weight.
  • kite's material allows the sides of the kite on the trailing edge to give way to the tension of the pads driven by the blades, in this way also the kite adopts a somewhat deformed shape at said ends of the trailing edge that help the rotation of the group. All this must be controlled by the computer supported by a specific software that will be responsible for governing based on the values previously indicated.
  • the leading edge of the blade is much thinner than the known propellers, so the resistance to rotation is significantly reduced.
  • the system of rotation of the blades and kites mounted on a hydraulic and pneumatic system as a sileblock eliminates vibrations and allows blades and kites to fall down in conditions of strong gusts of wind so that the group does not suffer and eliminates the possibility of breakages extending the useful life of the wind turbine assembly.

Abstract

La présente invention concerne un générateur éolien à pales et voiles qui comprend une nacelle à axe central creux en forme de cône dans lequel sont logés les mécanismes de rotation des pales. Le mécanisme comprend un système hydraulique à deux bras, installé sur un amortisseur pneumatique, chaque bras actionnant deux pales. Le générateur comprend, par conséquent, quatre pales, planes sur toute leur longueur, qui, au niveau de leur partie supérieure sont pourvues d'un élément tel qu'une voile, servant à les placer face au vent. Les voiles présentent un bord d'attaque courbe et un bord de fuite droit et sont fabriquées en matériau souple tel que de la fibre de verre ou du carbone. Le support et l'orientation des voiles sont obtenus au moyen d'un système situé au niveau de l'extrémité des pales qui est constitué de bras articulés fixés au niveau du bord de fuite des voiles, ainsi que d'axes pivotants fixés au niveau du bord d'attaque.
