Definitions

  • This invention refers to wind generator which transform the wind power.
  • the wind generators are used in order to transform the aeolian power into mechanic or electric one.
  • the defects of the wind generator are the fact that for its operation is required a mechanism, which orientates the wind generator towards the wind direction. This has a great frontal resistance to the wind flow so as not being broken the blades, the use of very durable materials is necessary. In addition this has a low output.
  • the defects of the wind generator with the vertical revolving shaft are: the wind generator of this type is useful only when the wind power is big enough and a motor is required which puts the wind generator into operate at the initial moment. This wind generator has also a low output.
  • the purpose of the present invention is to delete all the defects mentioned above.
  • the achievement of this purpose comes true as follows:
  • the four wind generator blades are hung, in pairs, on two separated horizontal shafts which between them, form an angle of ninety degrees (90°).
  • These two horizontal shafts are placed on a vertical shaft. Every blade pair on the horizontal shaft is placed in an angle of ninety degrees (90°) between themselves.
  • These horizontal shafts along with the blades can rotate around their shafts in an angle of ninety degrees (90°).
  • p - is the density of the wind
  • ⁇ - is the flow speed
  • L - are the linear dimensions of the blade.
  • the blade which is located lengthwise to the wind flow has minimal resistance to the wind.
  • the wind revolving the wind generator without any additional mechanism, locates automatically the pair blades one lengthwise and the other across to the flow, regardless the direction from which the wind blows.
  • the implementation of this construction enables the creation of a simple, reliable and with a great output wind generator. All the equipment, such as: the electric generator, the pump etc. are located on the ground. This means that to facilitated their installation, service and repair.
  • wind generators can be located into levels, so as the power of the wind generator will increase, as shown in Fig. 3.
  • FIG. 1 The main point of this invention is clarified by the drawing of Fig. 1, where the shape of the wind generator is depicted.
  • a vertical shaft (5) where two separated and in perpendicularly position horizontal shafts (6), (7), are hung through four bearings (8).
  • On these horizontal shafts (6), (7) are fixed blades (1), (3) and (2), (4) in pairs, which form an angle of ninety degrees (90°) between them.
  • the four stoppers are fixed (9).
  • the horizontal shafts (6), (7) along with the blades (1), (3) and (2), (4) can rotate around their shafts in an angle of ninety degrees (90°).
  • the limitation of the rotation of the horizontal shafts (6), (7) with the blades (1), (3) and (2), (4) is achieved by four stoppers (9).
  • FIG 2 in profile is shown the method of setting the horizontal shafts (6), (7) on the vertical shaft (5).
  • the wind flow ( ⁇ ) from the left (Fig. 1) turns the blade (3) lengthwise and the blade (1) across to the wind flow.
  • the blade (1) is positioned across to the wind flow, along of it leans of the stopper (9).
  • the vertical shaft (5) starts to revolve because the blade (3) resistance to the air is minimal while the one of the blade (1) is big.
  • the force under which the vertical shaft (5) is revolved depends on the wind speed and the surface of the blade which is located across to the wind flow.
  • the blade (4) will be found lengthwise and the blade (2) across to the wind flow leaning to the stopper (9). At this moment the blade (2) puts in motion the vertical shaft (5) by a turn of ninety degrees (90°). In continuity , the blade (1) will be lengthwise and the blade (3) across to the wind flow. The blade (3) sustain its across position to the wind flow by leaning on the stopper (9). Now the blade (3) operates as sail turning the vertical shaft (5) to an angle bigger than ninety degrees (90°). After that the blade (2), under the wind pressure, will be placed lengthwise and the blade (4) across to the wind flow. Therefore the blade (4), which leans on the stopper (9), acts as a sail, turning the vertical shaft (5). This procedure is continually repeated putting the vertical shaft (5) into revolving.

Abstract

L'invention concerne un aérogénérateur à aubes rotatives et à arbre rotatif vertical constitué par un arbre vertical (5), deux arbres horizontaux séparés (6, 7), quatre supports (8), quatre butées (9) et quatre aubes (1, 2, 3, 4). Sous la pression du vent, certaines aubes sont disposées transversalement par rapport au sens d'écoulement du vent, les aubes opposées étant orientées longitudinalement par rapport au sens d'écoulement du vent. Du fait de la grande différence de résistance aérodynamique entre ces aubes, l'arbre vertical (5) commence à tourner. Corrélativement, les autres aubes ne produisent aucune résistance au mouvement de rotation de l'arbre vertical (5). Elles sont en position neutre.
