Built-in fish collecting runner
The invention discloses a built-in fish collecting flow channel which comprises a fish collecting well communicated with an outlet of a water supply pipe of a water pump. The water pump water supply pipe inlet is communicated with a natural water area; the flow channel units are communicated with the fish collecting well, each flow channel unit comprises a plurality of volute chamber sections and rest pools which are communicated in sequence, the upstream of the first flow channel unit is communicated with the fish collecting well, and the downstream of the last flow channel unit is communicated with the flow channel outlet/fish channel inlet; the plane linetype of an overflowing surface on one side of a flow channel of the volute chamber section comprises a straight line section, an arc section and an offset section which are connected in sequence, and the plane linetype of an overflowing surface on the other side of the flow channel of the volute chamber section comprises a straight line section, an arc section and an offset section which are connected in sequence; and overflowing surfaces on two sides of the volute chamber section flow channel are arranged in a staggered manner. According to the invention, a vortex structure is formed by utilizing the guiding effect of the overflowing surface of the vortex chamber section of the flow channel, so that the local head loss of water flow is greatly increased, the overall gradient of the flow channel is increased, and the length of the flow channel is reduced, thereby shortening the upstream time of fishes.
本发明公开了一种内置式集鱼流道，包括集鱼井，与水泵供水管出口连通；所述水泵供水管进口与天然水域连通；多个与集鱼井连通的流道单元，每个流道单元包括多个依次连通的涡室段和休息池，第一个流道单元上游与集鱼井连通，最后一个流道单元下游与流道出口/鱼道进口连通；涡室段的流道一侧过流面平面线型包括依次连接的直线段、圆弧段和偏移段，涡室段的流道另一侧过流面平面线型包括依次连接的直线段、圆弧段和偏移段；涡室段流道两侧过流面呈错位布置。本发明利用流道涡室段过流面导向作用形成的涡流结构，大幅增加了水流局部水头损失，加大了流道总体坡降，减小了流道长度，从而缩短了鱼类上溯时间。
