Vertical slot fishway rest pool

The utility model relates to a vertical slot fishway rest pool. The vertical slot fishway rest pool comprises an upstream partition, an upstream guide plate, a downstream partition and a downstream guide plate; the upstream partition, the upstream guide plate, the downstream partition, the downstream guide plate and side walls on two sides of a vertical slot fishway form a pool body; the upstream partition and the downstream partition are arranged on the side wall on the same side; the upstream guide plate and the downstream guide plate are arranged on the side wall on the other side; the bottom surface of the pool body is horizontal or has a slope smaller than the slope of the bottom surface of the pool; the width of the pool body is equal to the width of the pool; the length of the pool body is twice the length of the pool. The pool body of which the bottom is horizontal or nearly horizontal is adopted, and the length of the pool is increased on the premise of not increasing the width of the fishway, so that the flow rate of current in the rest pool is attenuated, fish can fully rest in the rest pool and gather strength to continue swimming upstream. The rest pool without widening the fishway has important significance for complex-terrain reservoir construction, can be applied to various terrain conditions and solves the problem of arrangement of the vertical slot fishway rest pool.
