DEVICE USING WIND FORCE FOR ELECTRIC POWER SIGNAL GENERATION Russian patent published in 2000 - IPC

FIELD: wind-power engineering. SUBSTANCE: device has fixed mount, slewing shaft installed for turning in fixed mount, propeller body mounted for turning on upper end of slewing shaft, propeller shaft horizontally mounted for rotating in propeller body, propeller blade mounted for forward and reverse rotation on propeller shaft, propeller assembly incorporating propeller unit with flexible locking facilities that function to maintain propeller assembly in perpendicular position when wind velocity is below preset level and to allow for its deflection backward through preset angle when wind velocity is above preset level; it also has power signal generator connected to opposite end of propeller shaft for its control. EFFECT: improved effectiveness of power signal generation process due to varying wind energy being taken. 9 cl, 11 dwg
