VERTICAL-AXIS WIND TURBINE

WIPO Patent Application WO/2010/147301

A2

Disclosed is a vertical-axis wind turbine. The vertical-axis wind turbine comprises: a power generator; a rotary shaft, which extends in the vertical direction, for transferring rotational force to the power generator; a plurality of vertical blades disposed in a radial pattern on the rotary shaft, for rotating the rotary shaft by wind introduced; support members which extend outwardly from the rotary shaft, for enabling each of the vertical blades to hinge-rotate at the extended end of each of the support members around an axis parallel to the rotary shaft; and an elastic member disposed between each of the vertical blades and each of the support members, for elastically returning each of the vertical blades to a reference position when each of the vertical blades hinge-rotates by wind introduced, wherein the center of the hinge rotation of each of the vertical blades is positioned between the center of the width and the outer end of each of the vertical blades. The center of the hinge rotation of each of the vertical blades is tilted towards the outer side from the center of the width of each of the vertical blades, and thereby each of the vertical blades can rotate in stable balance when each of the vertical blades hinge-rotates while the rotary shaft rotates by wind introduced.
