BLADE PITCH CONTROLLER FOR SMALL-SCALE WIND POWER GENERATION SYSTEM

摘要

Disclosed is a blade pitch controller for a small-scale wind power generation system. Movable segments are integrally formed on an outer circumferential surface of the movable block, have moving grooves, and move backward and forward along with the movable block. Pitch adjustment pieces have adjustment pins formed at one end of each thereof, key grooves into which blade shafts are fixedly inserted are formed in the middles thereof, and pitch angles of blades are changed by angles changed when the movable block moves backward and forward. Pitch adjustment cylinders are coupled to fixing pieces formed at one end of each of the pitch adjustment pieces by hinges so as to be able to be located near the adjustment pins, are compressed when the movable block moves backward, and cause the pitch adjustment pieces to return to an original state after being compressed.

1. A blade pitch controller for a small-scale wind power generation system, comprising:
a plurality of movable segments that are integrally formed on an outer circumferential surface of the movable block, have moving grooves formed in outer circumferential surfaces thereof, and move backward and forward along with the movable block; pitch adjustment pieces in which adjustment pins inserted into the moving grooves are formed at one end of each thereof, key grooves into which blade shafts are fixedly inserted are formed in the middles thereof, and pitch angles of blades are changed by angles changed when the movable block moves backward and forward; and pitch adjustment cylinders that are coupled to fixing pieces formed at one end of each of the pitch adjustment pieces by hinges so as to be able to be located near the adjustment pins, are compressed when the movable block moves backward, and cause the pitch adjustment pieces to return to an original state after being compressed.
