Abstract:
1. A hydroelectric power generation system, having: a first water storage tank with a high-pressure water injection port on a bottom face; a runner which is stored in a condition of floating in the first water storage tank; and multiple transmission members that contact an outer periphery surface of the runner and transmit a rotational force of the runner to a principal axis of rotation in a generator unit; said hydroelectric power generation system characterized in that the runner has a casing of a cylindrical shape with a bottom and having an opening at a center of the bottom face; an introduction pipe that rises upward from the opening to introduce into the casing high-pressure water injected from the injection port; multiple first guide pipes that extend radially from around the introduction pipe to an inner side face of the casing; first injection nozzles provided at tips of the first guide pipes; and wherein a reactive force of the high-pressure water injected from the first injection nozzles in a circumferential direction of the casing is utilized to turn the runner.
