HIGH-DUTY WIND-DRIVEN POWER PLANT Russian patent published in 2011 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: wind-driven power plant includes vertical axis with blades, which is mounted in bearing supports, platform, arc screen covering some part of blades against action of wind, equipped with upper and lower rims, and support wheels contacting with the platform surface. Platform is mounted on supports, support wheels of arc screen are installed on it and lower bearing support of vertical axis is fixed. Upper bearing support of vertical axis is fixed on arc screen; support wheels of arc screen are mounted on chassis equipped with motor and transmission, having the possibility of being moved on the platform. On arc screen there fixed is wind parameter sensor; at that, movement of chassis is performed in automatic mode by means of the motor controlled with automatic angular orientation system of arc screen as per signals of wind parameter sensor. On platform there fixed is cylindrical guide surface, and on chassis there mounted are wheels with vertical rotation axis, which interact with guide cylindrical surface which can be equipped with a cap restricting the movement of support wheels in vertical plane.

EFFECT: invention provides the operation of high-duty wind-driven power plant in automatic mode with high use coefficient of wind energy.
