風力発電装置の組立方法、及びそれに用いられるカウンターウェイト

Document Type and Number:

Japanese Patent JP5872061

Kind Code:

B2

Abstract:

This wind power generator assembly method is provided with: a step for coupling a counterweight with a first flange of a rotor hub; a step for coupling a first wind turbine blade with a second flange of the rotor hub; a step for subsequently rotating the rotor hub so that a third flange of the rotor hub reaches a desired position; a step for adjusting the position of the center of gravity of the counterweight in the circumferential direction of the rotor hub; and a step for coupling a second wind turbine blade to the third flange after the step for adjusting the position of the center of gravity of the counterweight. When rotating the rotor hub, the position of the center of gravity of the counterweight and the position of the center of gravity of the first wind turbine blade are adjusted in such a manner as to be approximately symmetrical to each other relative to the rotation axis of rotation of the rotor hub. The position of the center of gravity of the counterweight is adjusted in such a manner that the position of the center of gravity of the counterweight, the position of the center of gravity of the first wind turbine blade, and the position of the center of gravity of the second wind turbine blade are approximately the same distance from axis of rotation of the rotor hub, and are positioned at approximately the same angular intervals around the rotor hub.
