WIND-DRIVEN GENERATOR PROPELLER Russian patent published in 2013 - IPC F03D3/06 

FIELD: power industry.

SUBSTANCE: wind-driven generator propeller includes horizontally located levers installed so that they can be rotated about vertical axis. On ends of levers there located are turning elements in the form of blades, which have the possibility of being rotated about vertical axis and kinematically connected through a reduction gear with transmission ratio of 1/2 to a synchronising gear installed so that it can be rotated about vertical axis. Propeller also has an orientation element formed with a turning impeller, a step-down reduction gear and an impeller screen; at that, turning impeller is connected through the step-down reduction gear to the synchronising gear on which the impeller screen is rigidly fixed. Blades of turning elements are made of two shutters hinged on a common axis and having the possibility of being fixed with calibrated force in a developed position.

EFFECT: easier operation of the device; increasing wind energy use coefficient and improving operating reliability at wide range of wind speeds, which will allow to arrange it in close proximity to residence buildings.
