Title:
VERTICAL WIND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2010/131891
Kind Code:
A2
Abstract:
The present invention relates to a wind power generator, and more particularly, to a vertical wind power generator configured with blades that are variable according to the wind speed in order to increase power generating efficiency. The vertical wind power generator according to the present invention comprises: a rotating shaft formed perpendicular to the ground surface so as to be rotatable; a vertical blade provided on the rotating shaft to rotate the rotating shaft by means of wind power, and having a surface area that is variable according to the wind speed; and a generating unit having said rotating shaft provided vertically at the top thereof, and including a generator for generating electrical using the rotation of the rotating shaft, and rotation transmission means for transmitting the rotation of the rotating shaft to the generator. Accordingly, the vertical wind power generator according to the present invention has the advantages of being able to improve generating efficiency by increasing the surface area of the blade in a low wind speed environment, and of preventing the mechanical failure of the power generator by minimizing the surface area of the blade in a high wind speed environment.
