Document Type and Number:
WIPO Patent Application WO/2012/137311
Kind Code:
A1
Abstract:
[Problem] To provide a renewable energy generator device wherein hydraulic piping between a hydraulic pump installed in a nacelle and a hydraulic motor installed in the vicinity of a tower base end can support a turning motion of the nacelle. [Solution] In the renewable energy generator device (1, 100), the hydraulic pump (8) in the nacelle (4) and the hydraulic motor (10) in the vicinity of the base end (2A) of the tower (2) are connected using 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 has a first inside pipe (22, 72) and a first outside pipe (24, 74). The second double pipe has a second inside pipe (32, 82) and a second outside pipe (34, 84). An inside duct (44) is formed by the first inside pipe (22, 72) and the second inside pipe (32, 82), and an outside duct (46) is formed by the first outside pipe (24, 74) and the second outside pipe (34, 84). One of either high pressure oil or low pressure oil flows in the inside duct (44), and the other of either high pressure oil or low pressure oil flows in the outside duct (46).
