WIND-DRIVEN POWER DEVICE Russian patent published in 2011 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: device includes vertical fixed post on which with possibility of free rotation there installed is central shaft interacting through a pair of conical gear wheels to electric generator, and two tiers of evenly spaced in pairs symmetrical horizontal levers rigidly attached to central shaft, the ends of which are hinged to flat blades which are non-symmetrical relative to rotation axes. Blades interact with single-sided stops installed on the appropriate horizontal levers. Device also includes rotation speed changing points interacting with central shaft, which are made in the form of centrifugal slide having the shape of cylinder and put on lever. Centrifugal slides are connected to central shaft by means of tension spring and can be installed on horizontal levers of upper tier. On vertical shaft there installed is cylindrical slide interacting through ropes to the above centrifugal slides. One-sided stops can be made in the form of spring-loaded retractable latches the tongues of which have the shape of wedge, or in the form of spring-loaded hinges some halves of which are connected to blades, and the other interact with the appropriate levers.

EFFECT: improving synchronisation of rotation of outlet shaft at simplifying the design.
