Abstract
To provide a small hydraulic power generator which adjusts an angle that water flow contacts with a water turbine while utilizing water flow near a water surface, at which flow speed becomes high, to enable efficient power generation according to a water amount in a water passage without decreasing the flow speed of water guided to the water turbine.SOLUTION: A small hydraulic power generator includes: a first water guide passage 20 located at the upstream side; a second water guide passage 30 located at the downstream side; a water turbine 40 located in the most downstream side of these water guide passages and having a rotary shaft in a direction orthogonal to water flow; a lateral movement device 50 which allows the second water guide passage 30 to move in an upstream direction or a downstream direction; and a vertical movement device 60 which allows the water turbine 40 to move in a vertical direction. The structure allows the small hydraulic power generator to generate power efficiently according to a water amount in a water passage.SELECTED DRAWING: Figure 1
