<P>PROBLEM TO BE SOLVED: To provide a wind power generation device capable of generating power by preventing damage of a wind turbine and a wind collecting part in strong wind by rotating the wind turbine by guiding and releasing wind by the wind collecting part composed of a plurality of wind collecting vanes. <P>SOLUTION: This device is provided with the wind turbine 2 provided with a plurality of blades 21 around a rotary shaft 5 along the rotary shaft 5, a generator 7 driven by rotation of the rotary shaft 5, the wind collecting part 4 receiving wind in an outer circumference space and guiding the same toward the wind turbine 2 at the outer circumference side of the wind turbine 2. The wind collecting part 4 is constructed to adjust direction and quantity of wind received by the same for guiding the wind to directions other than the wind turbine 2 in strong wind during which air feed quantity to the wind turbine is excessive. The wind turbine 2 and the wind collecting part 4 are constructed as a single unit, the unit is additionally provided by connecting the rotary shaft 5 of the wind turbine 2 in a lateral direction, and the unit is constituted by coupling in such a manner that an adjustment mechanism of wind direction and wind quantity of the wind collecting part 4 can be operatively connected. <P>COPYRIGHT: (C)2009,JPO&INPIT |
