  • Fig. 1 shows the structural layout of the wind power generator.
  • Fig. 2 shows a cross section of the wind power generator with three possible variants of the design of the guide plates and the system for optimizing the operation of the rotor. Detailed description of the invention
  • the wind power generator comprises a rotor with a vertical axis of rotation inside a fixed stator composed of wind guide plates (1).
  • the rotor may have a diameter of e.g. 70 cm, and the stator of wind guide plates a diameter of 1.2 m; their height (length), may be e.g. 2.2 m.
  • Wind guide plates (1) are arranged between fixed toroid rings (2).
  • the rotor is formed by blades (4) attached to supporting cylinder (3). They form slit aperture (5) between themselves and supporting cylinder (3).
  • Supporting cylinder (3) is mounted in bearings (6), and is mechanically connected to a converter of the mechanical energy of the rotor into electricity, e.g. to a magneto-electric generator (not shown).
  • Each blade (4) has longitudinal main swirlers on the front of its plane.
  • the swirlers are in the form of delta- shaped or I-shaped projections (7) perpendicular to the plane of blades (4).
  • the side facets of the delta-shaped projections are concave or flat.
  • Projections (7, 14) may be made e.g. in one with blades (4), or may be independent elements fixed firmly to blades (4).
  • Blades (4) may be solid (all metal) or hollow. They may be made e.g. in the form of three-dimensional hollow structures of thin metal by the pressing method.
  • the cavity in hollow blades (4) may be filled with a polymer foam filler such as solid foam polystyrene.
  • Each wind guide plate (1) is set radially along the axis of the rotor, is hollow, and has a smooth bend (8) in the narrow part of the confuser channel (9) formed by adjacent wind guide plates (1) to guide the flow of air running onto the wind power generator at an angle of 80°-90° to the longitudinal section of rotor blade (4), and has at least one rotating plate (10) turned by a drive (not shown), said plate being arranged along the surface of wind guide plate (1) with axis of rotation (12) parallel to the axis of the rotor.
  • Supporting cylinder (3) has extendable plates (13) arranged radially and able to be displaced radially to close off or alter the size of slit aperture (5) between bearing cylinder (3) and each of the rotor blades (4).
  • Axis of rotation (13) of each rotating plate (12) may be arranged in the middle part of the cross section of wind guide plates (1), on which are mounted two rotating plates (12) arranged either side of wind guide plate (1), or the axis of rotation (13) of each turning plate (12) may be arranged on the entry sector of wind guide plate (1), the latter having on it one rotating plate (12) or two rotating plates (12) either side of wind guide plate (1) (see Fig. 2, where all the variants described above are shown).
  • the wind power generator operates in the following manner.
  • the wind flow runs onto wind guide plates (1), is accelerated on them and flows onto blades (4) of the rotor, so that the device accomplishes useful work by the rotation of the rotor. Furthermore, the air flow exerts direct pressure on blades (4), between which a high pressure zone is created.
  • the presence of slit aperture (5) enables possible breakaway of the airflow in this zone to be prevented - such breakaway, if it occurred, would reduce the effective working area of blades (4), by removing the compacting of the air from the space between the blades.
  • the excess pressure is passed through slit aperture (5) into the space beyond the blade, which is a low pressure zone forming a vortex cavity.
  • Extendable plates (13) make it possible to alter or close off the slit aperture and thus to regulate the pressure difference created on each blade (4), and consequently, to regulate the rotor operating regime.
  • the main swirlers on the front of blades (4) serve for additional take-off of the energy of mechanical motion of the air flow, including that part of it which slides off blades (4) after they have turned through a certain angle.
  • the flow of air coming onto the main swirlers in the form of projections (7) is swirled by the projections, slowing it down, and thus taking off additional energy from the air flow and passing it to the rotor.
  • the shape and dimensions of projections (7) exert significant influence on vortex formation (turbulence induction).
  • Projections (7) assist swirl formation on the front of blades (4) for different vectors of the oncoming air flow, which raises the efficiency of the rotor.
  • the height of projections (7) is determined for the specific design of the wind power generator, e.g. experimentally, by the increase in efficiency. Their number is selected depending on the power output for which the rotor of the wind power generator is designed.
  • the air flow entering the confuser channel is speeded up in it as it passes through due to the narrowing of the cross section in the confuser channel (equalizing the continuity of the jet), then changes the direction of the flow vector, due to the bend in wind guide plate (1), towards the frontal surface of rotor blades (4), and goes onto blades (4) at an angle of 80°-90° to the longitudinal section of rotor blade (4), enabling maximum use to be made of the kinetic energy of the air flow for conversion into mechanical work. As the speed of the oncoming air flow increases, so does the generation of electricity in the electric generator.
  • rotating plates (10) are installed in the gap of the confuser channel formed by wind guide plates (1), at its entrance or in the middle part of it.
  • the rotating plates can regulate the passage section of the confuser channel and thus also the flow rate of the incoming air flow (see Fig. 2).
  • rotating plates (10) are diverted to close off part or all of the passage section of the confuser channel.
  • the rotating plates (10) may be turned by electromechanical, pneumatic or hydraulic rotating mechanisms.
  • the parameters of the rotor are optimized for each wind speed value by altering the width of slit aperture (5) and the passage section of the confuser channel formed by wind guide plates (10).
  • a wind power generator made in accordance with the invention has efficiency 15-20% higher by comparison with analogous known ones. It is more efficient to use and cheaper to make.
  • This invention can be used everywhere that it is possible to utilize wind energy to produce mechanical energy and/or electricity.

Abstract

La présente invention concerne le domaine de l'énergie éolienne et peut être utilisée dans des aérogénérateurs pour produire de l'énergie, principalement de l'électricité. Le générateur éolien contient un rotor sur un axe de rotation vertical, ledit rotor étant placé dans un stator fixe de plaques de guidage du vent et étant formé par des pales fixées à un cylindre porteur, les pales formant une ouverture en fente le long de leurs bases entre elles et le cylindre porteur, chacune des pales comportant des coupelles de turbulence principales longitudinales le long de l'avant de son plan sous la forme de saillies en forme de triangle ou de I perpendiculaires au plan des pales ; et, à l'arrière du plan de chacune des pales, sur son bord vertical le plus près de l'axe du cylindre porteur, se trouve une coupelle de turbulence secondaire sous la forme d'un épaississement longitudinal possédant une coupe transversale en forme de triangle ; chaque plaque de guidage du vent est disposée de façon radiale le long de l'axe du rotor, est plate et se courbe progressivement dans la partie étroite du canal conique formé par les plaques de guidage du vent adjacentes afin de diriger l'écoulement d'air circulant sur le générateur éolien selon un angle de 80 à 90° par rapport à la coupe transversale longitudinale de la pale du rotor, et possède au moins une plaque mise à tourner par un entraînement, ladite plaque étant située le long de la surface de la plaque de guidage du vent avec un axe de rotation parallèle à l'axe du rotor, pendant que le cylindre porteur possède des plaques extensibles disposées de façon radiale et installées de sorte qu'elles puissent être déplacées de façon radiale et qu'elles puissent se fermer ou modifier la taille de l'ouverture en fente entre le cylindre porteur et chacune des pales du rotor. Il en résulte que l'aérogénérateur obtient une plus grande efficacité, et que son fonctionnement à des vitesses de vent élevées et pour une utilisation avec des générateurs éoliens haute puissance est optimisé.
