WIND-DRIVEN UNIT WITH HORIZONTAL ROTATION AXIS OF WIND TURBINE AND POWER LIMITATION Russian patent published in 2011 - IPC F03D1/00 F03D7/02 

FIELD: power industry.

SUBSTANCE: wind-driven unit with horizontal rotation axis 2 of wind-driven turbine 1 and power limitation has support 5 of wind-driven unit, side shovel 15, power counteracting unit with application points of force between head of wind-driven unit and device responding to wind direction, put on vertical axis in head with possibility of turn by not less than 90°. As the device responding to wind direction there used is tail vane 12 the head 14 of which is rigidly connected to side shovel 15 perpendicular to tail vane plane 12. Axis 11 of tail vane 12 is connected by means of mechanical transmission to pin gear 6 on support 5 by means of shaft 8 passing coaxially through vertical axis 13 in head 14. Axis 13 in head 14 is hollow.

EFFECT: improving serviceability and reliability of operation of wind-driven unit.
