Self-adaptive adjusting water replenishing fishway for floating dock

Abstract

The invention discloses a self-adaptive adjusting water supplementing fishway for a floating dock. The self-adaptive adjusting water supplementing fishway for the floating dock comprises a fishway body, wherein the bottom end of the fishway body is rotationally connected with a floating dock structure, an auxiliary swimming structure is arranged in the fishway body, and an adjusting structure used for adjusting the angle of an auxiliary swimming plate of the auxiliary swimming structure is arranged on the floating dock structure. According to the self-adaptive adjusting water supplementing fishway for the floating dock, the angle of the fishway body and the angle of the auxiliary swimming plate can be adjusted in a self-adaptive mode, and the auxiliary migration process of fishes is effectively conducted.

Description

technical field [0001] The invention relates to the technical field of water replenishment fishways, in particular to a water replenishment fishway with self-adaptive adjustment of a floating dock. Background technique [0002] The fishway is the channel for fish to migrate through the artificial tank of the sluice or dam. The design of the fishway mainly considers the upward habit of the fish. In the downstream of the dam, the fish often rely on the attraction of the water to enter the fish. In the fishway, the fish rely on their own strength to overcome the flow velocity and swim upstream. The design of the fishway mainly considers the upward habit of the fish. In the downstream of the gate and dam, the fish often rely on the attraction of the water flow to enter the fishway. The fishway needs to rely on its own strength to overcome the flow velocity and swim upstream, while the downstream fish can go downstream through the fishway; when the traditional fishway is installe...

[0002] The fishway is the passage for fish to migrate through the artificial tank of the sluice or dam. The design of the fishway mainly considers the upward habit of the fish. In the downstream of the dam, the fish often rely on the attraction of the water to enter the fish. In the fishway, fish rely on their own strength to overcome the flow velocity and swim upstream. The design of the fishway mainly considers the upward habit of fish. The fishway needs to rely on its own strength to overcome the flow velocity and swim upstream, while the downstream fish can go downstream through the fishway; when the traditional fishway is installed and used, it is not easy to adjust the fishway. When the upstream and downstream water levels change and the drop changes, The fishway cannot connect the upstream and downstream well, which is not conducive to fish migration, and there is no good fish rest platform on the fishway, and there is no good support and auxiliary resting device when the fish upstream is weak, which affects the fish migration efficiency
