WIND POWER GENERATION DEVICE CAPABLE OF VARYING ANGLE OF ROTARY BLADES, WHICH GENERATES EVEN AND STRONG ROTATING FORCE IN A FIXED DIRECTION REGARDLESS OF WIND BLOWING DIRECTION

摘要

PURPOSE: A wind power generation device capable of varying angle of rotary blades is provided to increase service life by preventing overload on a rotary shaft and a rotary blade.;CONSTITUTION: A wind power generation device capable of varying angle of rotary blades comprises a housing(110), a generator(120), a rotary shaft(140), a rotating arm(150), an eccentricity rotation blade(160), and a stopper(170). The generator is installed in a housing and generates electricity. The rotating arms are installed on the lower part of the rotary shaft around the rotary shaft. A support stand(151) of the rotating arm is formed outside of the rotary shaft. The stopper elastically restricts the rotation angle of the eccentricity rotation blade.;COPYRIGHT KIPO 2012
