WIND-DRIVEN POWER PLANT WITH DARRIEUS ROTOR Russian patent published in 2012 - IPC F03D3/06 F03D11/04 F03D11/02 

FIELD: power industry.

SUBSTANCE: wind-driven power plant includes rotor made in the form of vertical shaft with bent or straight blades attached to it by means of cross beams. Rotor shaft is suspended by means of a swivel on bearing, which is installed on lower side of plate from which tie rods are branched, the other ends of which are hitched through blocks and fixed on masts symmetrically located around the rotor. Each mast is fixed at least with two tie rods and anchors. Lower end of suspended rotor shaft is connected to shaft of energy receiver. Rotor shaft is loaded with longitudinal tension force which is taken at the top with radial thrust bearings of swivel, and at the bottom - with radial thrust bearings of shaft of energy receiver or an individual sleeve fixed with anchors. Blades are made in the form of tight fabric cover. Cover is made in the form of a sleeve with ribs of aerodynamic profile, which are arranged inside the sleeve. Ribs are attached along their perimetre to the cover material. Inner space of the cover is connected by means of air pipeline to compressed air source in order to maintain the specified excess pressure inside the blade.

EFFECT: reducing the weight and improving stability and reliability of the plant.
