RENEWABLE ENERGY POWER GENERATING APPARATUS

摘要

A renewable energy power generating apparatus includes: a tower; a nacelle including a nacelle base plate disposed on an upper part of the tower, and a nacelle cover supported on the nacelle base plate and including an opening formed along an outer peripheral surface of an upper end of the tower; an oil-using unit disposed in an interior space of the nacelle; a yaw rotation bearing including a first rotation ring fixed to the tower and a second rotation ring fixed to the nacelle base plate, and rotatably supporting the nacelle on the tower; a seal member disposed so as to fill a gap between the tower and the nacelle cover; a seal cover attached to a part of a stationary section including the tower and the first bearing ring, and disposed above the seal member so as to cover the gap; and an oil storing part disposed below the seal cover and in a rotational section including the nacelle. The oil storing part is configured to receive leaked oil which leaks from the oil using unit and flows down the seal cover.
