BLADE ANGLE CONTROL SYSTEM OF WIND POWER GENERATOR

摘要

The present invention relates to a blade angle control apparatus of a wind power generator, and more specifically, to a blade angle control apparatus of a wind power generator which automatically controls a blade angle according to wind strength. The blade angle control apparatus of a wind power generator comprises: a shaft to transfer power; a plurality of blades radially mounted on a rotor mounted on an end of the shaft; a housing having a hollow shape into which the shaft is inserted and comprising a spiral groove of a spiral shape formed along an inner circumferential surface thereof; a stroke mounted on one side of the housing and provided with screw threads of a spiral shape formed on an outer circumferential surface thereof to be meshed with the spiral groove of the housing to be moved in left and right directions; and an angle control means radially disposed on each blade from the stroke.
