Partition plate type fishway with inlet water supplementing and energy dissipation structure
The partition plate type fishway comprises a horn-shaped fish inlet, a fishway side wall, a pebble bed, a fishway bottom plate, a partition plate and a fish outlet, a sunken inlet water replenishing pool with an opening in the top is arranged in the fishway bottom plate on the upstream of the horn-shaped fish inlet, and the inlet water replenishing pool is connected with a water replenishing valve chamber on the outer side through a water replenishing pipe; a flow adjusting valve and a flow meter are arranged on a water supplementing pipeline in the water supplementing valve chamber, a grating is arranged on an opening in the top of the inlet water supplementing pool, a pebble layer is laid on the grating, a pebble layer is also laid on the fishway bottom plate, and the pebble layer on the grating is flush with the upper surface of the pebble layer on the fishway bottom plate. Water replenishing flow is subjected to energy dissipation through a grating at the top of the water replenishing pool and an overlying pebble bed and then enters a fishway, and flow loss is prevented through water stopping between the water replenishing pool section and upstream and downstream; water supplementing flow and water flow in the fish tank are lowered to a downstream river channel through the horn-shaped inlet, and the flow speed of the fishway inlet position is increased so as to achieve the fish luring effect.
本发明公开了一种带有进口补水消能结构的隔板式鱼道，包括喇叭形进鱼口、鱼道侧墙、卵石层、鱼道底板、隔板、出鱼口，在喇叭形进鱼口上游的鱼道底板内设置下陷的顶部敞口的进口补水池，进口补水池通过补水管与外侧的补水阀室相连，补水阀室中补水管管路上设置有调流阀和流量计，进口补水池顶部敞口上设置有格栅，格栅上面铺设卵石层，鱼道底板上也铺设卵石层，格栅上的卵石层与鱼道底板上的卵石层上表面相平。通过补水池顶部的格栅和上覆卵石层对补水流量进行消能后进入鱼道，补水池段与上下游之间通过止水，防止流量损失；补水流量和鱼槽内水流同时经喇叭形进口下放至下游河道，提高鱼道进口位置流速以达到诱鱼效果。
