Abstract

PURPOSE: To prevent a current of more than allowable range from flowing to a generator by providing shutters which close by the resilient force of springs and open upon high speed rotation by the rotational force of a propeller, in openings provided in vanes of the propeller, thereby to suppress the high speed rotation of the propeller.
CONSTITUTION: At the time of weak wind when the rotation of a propeller 1 is slow, and a centrifugal force applied on a weight 11 is small, the weight 11 is pulled in the concentrical direction by the resilient tensile force of a spring 5 and the opening 3 of the shutter 4 is closed. At the time of strong wind, when the rotation of the propeller 1 becomes fast and the centrifugal force applied on the weight 11 becomes large, the weight 11 is moved in the centrifugal direction by the centrifugal force counter to the resilient force of the spring 5, and the shutter 4 is gradually opened in response to the rotation of the propeller 1. Accordingly, the wind receiving area of the vane 2 becomes small, and the power of wind flowing against the vane 2 is lost to suppress the rotation of the propeller 1.
