WIND-ELECTRIC POWER PLANT Russian patent published in 1997 - IPC

FIELD: wind-electric power engineering. SUBSTANCE: power plant has tower, windwheel with shaft, step-up gear, dispensing device that forms working flows and incorporates flywheel, coupling, generator, and process flow with starting gear; it also has coupler, additional off-line flow step-up gears, mechanical brake, additional gear wheel, and intermediate shaft. Dispensing device is built integral with step-up gear to form multiflow dispensing booster incorporating slow-speed input shaft with central large gear wheel and sets of output shafts with small gear wheels mounted in parallel on one side over periphery. Each output high-speed shaft of multiflow dispensing booster placed in working flow is coupled with slow-speed input shaft of additional off-line step-up gear through clutch and additional intermediate shaft easily passed through hollow high-speed output shaft of multiflow dispensing booster separating clutch mounted on windwheel side from additional off-line step-up gear placed on opposite side from multiflow dispensing booster. High-speed output shaft of additional off-line step-up gear is coupled in working flow with flywheel and in process flow, with brake and starting gear via additional gear wheel combined with brake drum. Clutch may be made in the form of multidisk engageable friction clutch with drive, reduction gear, and motor series-interconnected in clutch drive incorporating screw-and-nut assembly; screw is coupled with reduction gear output shaft and nut, with pushrod of disengageable clutch. Windwheel shaft may be made hollow and coupled with input shaft of multiflow booster through gear coupling with driving members of blade operating mechanism placed inside. Plant brake may be of mechanical, block, or electromagnetic type. Additional off-line step-up gears are mounted on multiflow dispensing booster case coaxially to its output shafts with aid of flanges. EFFECT: improved design. 12 cl, 4 dwg
