Abstract

It is intended to provide a power generating apparatus of renewable energy type in which a hydraulic pipe between a hydraulic pump installed inside a nacelle and a hydraulic motor installed near a bottom part of a tower can handle the turning motion of the nacelle. In the power generating apparatus of renewable energy type (l, 100),a hydraulic pump (8) inside the nacelle (4) and a hydraulic motor (10) near an base end part (2A) of a tower (2) are connected by a first double pipe (20, 70) and a second double pipe (30, 80). The first double pipe is rotatably connected to the second double pipe. The first double pipe includes a first inner pipe (22, 72) and a first outer pipe (24, 74). The second double pipe includes a second inner pipe (32, 82) and a second outer pipe (34, 84). The first inner pipe (22, 72) and the second inner pipe (32, 82) communicate with each other to form an inner passage (44). The first outer pipe (24, 74) and the second outer pipe (34, 84) communicate with each other to form an outer passage (46). One of high-pressure oil and low-pressure oil flows in the inner passage (44), whereas the other of high-pressure oil and low-pressure oil in the other of the outer passage (46).
