Single fishway outlet structure capable for realizing layered fish passing
The invention discloses a single fishway outlet structure for realizing layered fish passing. The single fishway outlet structure comprises a single fishway outlet, wherein the rear end of the single fishway outlet is sequentially provided with more than two layers of connecting flow channels from bottom to top along the height direction according to the variable amplitude of the fish passing water level along the water flow direction, the tail ends of the connecting flow channels communicate with a main fishway channel, and the connecting flow channels are composed of lower-layer flow channels and upper-layer flow channels or composed of the lower-layer flow channel, more than one middle-layer flow channel and the upper-layer flow channel. According to the structure, more than two layers of connecting flow channels are sequentially arranged at the single fishway outlet from bottom to top in the height direction along the water flow direction according to the amplitude of the fish passing water level, so that the layered fish passing requirement is met, the number of the outlets of the fishway is reduced, the length of the fishway is shortened, and the investment is effectively saved.
本发明公开了一种实现分层过鱼的单鱼道出口结构，包括有单鱼道出口，单鱼道出口后端根据过鱼水位变幅顺水流向沿高度方向从下到上依次设置2层以上的衔接流道，衔接流道末端与总鱼道渠连通；所述衔接流道由下层流道及上层流道或下层流道、1层以上的中层流道和上层流道构成。该结构根据过鱼水位变幅在单鱼道出口顺水流向沿高度方向从下到上依次设置两层以上的衔接流道实现了分层过鱼要求，减少了鱼道出口的数量，缩短了鱼道的长度，有效节省了投资。
