A blade locking device for wind power is characterized in that a base is fixedly installed on a hub of a wind power generator, a shaft sleeve and a bearing seat are installed on the base, and the bearing seat is connected with a transition seat; the bearing is mounted in the bearing seat; one end of the lead screw is connected with the bearing and locked through the locking nut, the other end of the lead screw is in threaded connection with the tooth locking pin which is of a cylindrical structure, one end of the tooth locking pin is sleeved with the shaft sleeve, and the head of the other end of the tooth locking pin is a gear which can be meshed with a variable-pitch bearing gear on the wind turbine. The gear motor is arranged on the transition seat, and an output shaft of the gear motor is connected with the lead screw. The gear motor drives the lead screw to drive the locking tooth pin to move axially, unlocking and resetting of the blade locking device are achieved, the locking tooth pin is meshed with a
