ROTOR-TYPE WIND-OPERATED POWER PLANT

摘要

The present invention relates to power engineering, in particular to designs for wind power installations, and can be used for generating electrical energy by converting energy from an air stream discharged from various places (underground railways, factory floors, etc.) by ventilation systems, and also in wind power plants. The wind-operated power plant comprises a rotor which is in the form of a disc with blades mounted thereon, said blades being in the form of aerodynamic wings and being arranged so that a gap exists between the blades and the rotor shaft, which is mechanically connected to the shaft of an electric generator, a cowl which is mounted on the shaft upstream of the rotor in the direction of the air stream and encircles the gap between the internal edges of the blades, and a confuser which is arranged upstream of the rotor in the direction of the stream. The blade ends are tapered towards the axis of the shaft. The confuser is mounted on the peripheral parts of the blade ends so that a gap exists between the confuser and the cowl. As a result, an increase in the fullness of use of the energy from the wind stream is achieved, and also the design of a rotor-type wind-operated power plant and the operation thereof are substantially simplified.
