Water power revolving door type fishway

The invention provides a water power revolving door type fishway. The water power revolving door type fishway mainly comprises a fish passing tunnel, a round chamber, a revolving door and a water wheel. The water passing tunnel is arranged in a dam. The round chamber is communicated with the downstream end of the fish passing tunnel. The revolving door is placed in the round chamber. The solid wall of the side face of the revolving door forms an arc with a 270-degree central angle on the plane. Internal space of the round chamber is alternately communicated with the fish passing tunnel and downstream water of the dam in a revolving state, and the purposes of fish passing and water retaining are achieved. The revolving door is provided with a large number of small holes to control the flow speed of water flow in the fishway. A rotary shaft of the water wheel is connected with a rotary shaft of the revolving door through a reduction gear, so that power is supplied to revolving of the revolving door. The water power revolving door type fishway is high in adaptability to dam height and good in coordination with reservoir incoming water and hydro-junction operation.
