Problems solved by technology

[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

Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 6 As shown in the figure, an adaptively adjusted water replenishing fishway of a floating dock includes a fishway body 1, the bottom end of the fishway body 1 is rotatably connected with a floating dock structure 5, and an auxiliary swimming structure 2 is arranged in the fishway body 1 , the floating dock structure 5 is provided with an adjustment structure 6 for adjusting the angle of the auxiliary swimming plate 21 of the auxiliary swimming structure 2 .

[0028] Preferably, the auxiliary travel structure 2 includes a plurality of auxiliary travel plates 21, each auxiliary travel plate 21 is rotatably connected with one end of a linkage column 22, and the other end of the linkage column 22 is rotatably connected with one end of the slider 23. The other end of the slider 23 is slidably connected with the fis...

Abstract

The invention discloses a water replenishment fishway adaptively adjusted by a floating dock. The structure is provided with an adjustment structure for adjusting the angle of the auxiliary swimming plate of the auxiliary swimming structure; the invention can adaptively adjust the angle of the fishway body and the auxiliary swimming plate, and effectively assist the fish in the migration process.

Description

technical field [0001] The invention relates to the technical field of water replenishment fishways, in particular to a water replenishment fishway for self-adaptive adjustment of a floating dock. Background technique [0002] The fishway is the channel for fish to migrate, and the artificial water tank for fish to migrate through the sluice or dam. The design of the fishway mainly considers the upward behavior of the fish. In the downstream of the sluice and dam, the fish often rely on the attraction of the current to enter the fish. In the fishway, fish can overcome the flow speed and swim upstream in the fishway. The design of the fishway mainly considers the upward behavior of fish. In the fishway, it is necessary to rely on its own strength to overcome the flow speed and swim upstream, while the descending fish can flow downstream through the fishway; when the traditional fishway is installed and used, the adjustment of the fishway is not easy. The fish pass cannot con...
