PROBLEM TO BE SOLVED: To ensure high power generation efficiency without restricting the installation location of a device as much as possible.SOLUTION: In a hydraulic power generation device, a drive part 3 for rotating a rotating body 2 is composed of an annular member 5 longer than the circumference 2a of the rotating body 2. The annular member 5 consists of a suspension part 7 extending along the circumference 2a of the rotating body 2 and a hanging part 8 hanging down therefrom while not extending along the circumference 2a of the rotating body 2, and is provided with water receiving parts 6 at a predetermined interval. The supply of water W from a water resource S to the water receiving parts 6 allows the rotating body 2 to rotate more efficiently for potential energy corresponding to the length of the hanging part 8. Furthermore, an amount of power generation can be increased by making the length of the hanging part 8 longer even without changing the diameter of the rotating body 2, and therefore the installation location of the device is hardly restricted, and the hydraulic power generation device can be installed relatively easily even in a small space where a conventional water wheel cannot be installed. |
