Title:
FLUID FORCE POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/173139
Kind Code:
A1
Abstract:
Provided is a fluid force power generation device in which shaft power loss caused by the fact that one propeller works as a brake on the other propeller can be prevented and thereby the power generation efficiency can be improved. A first propeller (5) and a second propeller (6) having different rotational directions from each other are disposed on both ends of a main body (4) and are coupled to a first rotational shaft (7) and a second rotational shaft (8), respectively. The power of the first rotational shaft (7) is transmitted to a first element (41) (differential (40)) by a first one-way clutch (20), and the power of the second rotational shaft (8) is transmitted to a second element (42) (differential (40)) by a second one-way clutch (30). When the number of rotations of the first propeller (5) decreases and the number of rotations of the first rotational shaft (7) becomes relatively smaller than that of the first element (41), the power transmission from the first element (41) to the first rotational shaft (7) is blocked by the first one-way clutch (20). The first propeller (5) is prevented from working as a brake on the second propeller (6) having the larger number of rotations, the shaft power loss can be prevented, and thereby the power generation efficiency can be improved.
