WIND ENERGY CONVERSION SYSTEM INCORPORATING AUTOMATIC PROTECTIVE GEAR Russian patent published in 2007 - IPC F03D3/00 

FIELD: wind-electric power engineering; automatically protected wind energy conversion systems.

SUBSTANCE: proposed wind energy conversion system incorporating automatic protective gear has vertical positioning shaft that mounts core with several bushings equally spaced apart; shaft carrying bevel gear wheels on both ends is passed through these bushings; these gear wheels are engageable with gear wheel having twice as small number of teeth and all of them constitute part of vertical positioning shaft; bevel gear wheels on other side disposed on opposite ends of bushings are engageable with similar bevel gear wheels disposed on vertical shafts mounted in bearings; spherical or articulated joint is provided in top part of vertical shafts for connection to upper inclined cantilever parts of ascending shafts that function as supports and guides for wind-driven folding blades.

EFFECT: enhanced reliability, operating effectiveness, and efficiency of system.
