Abstract
A blade attaching method is provided for a power generating apparatus which may include a blade, a hub having a blade attaching part, a bearing, a generator, and a pitch drive mechanism. The method may include, but is not limited to: a step of attaching a suspension device to the blade; a step of lifting the blade; a step of holding the blade so that the blade attaching part of the hub faces the blade root part of the; a step of rotating the blade attaching part by the pitch drive mechanism to a set angular position while holding the hub; and a step of fixing the blade to the hub after rotating the blade attaching part to the set angular position.
Claims10
A blade attaching method for a power generating apparatus of renewable energy type which comprises a blade, a hub having a blade attaching part to which the blade is attached and a bearing which supports the blade attaching part rotatably, a generator to which a torque is inputted from a side of a rotor including the blade and the hub, and a pitch drive mechanism which adjusts a pitch angle of the blade by rotating the blade attaching part, the method comprising the steps of;
- holding the blade in such a manner that the blade attaching part of the hub faces a blade root part of the blade;
- rotating the blade attaching part to a set angular position by the pitch drive mechanism in such a state that the blade is held;
- and
- after rotating the blade attaching part to the set angular position, fixing the blade to the hub.
