Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 6 As shown in the figure, a buffer fishway suitable for emergency flood discharge with reduced damage includes a fishway body 1, a migratory channel 3 is arranged in the fishway body 1, and one end of the fishway body 1 is rotatably connected with the fixed seat 2 , and the other end is rotatably connected with the counterweight floating dock 4 , and a plurality of swingable buffer plates 5 are hinged in the migratory channel 3 .

[0031] Preferably, the buffer plates 5 are arranged equidistantly and parallel to each other along the length direction in the migratory channel 3 , and a transmission link 6 is provided between each buffer plate 5 , and the side surfaces of the transmission link 6 and the buffer plate 5 rotate. connect. After this design, through the swing of one buffer plate 5, a plurality of buf...

Abstract

The invention discloses a buffering fishway and a buffering method suitable for emergency flood discharge with reduced damage. The buffering fishway includes a fishway body, and a migratory channel is arranged in the fishway body, and one end of the fishway body rotates with a fixed seat. The other end is connected to the counterweight floating dock in rotation, and a plurality of swingable buffer plates are hinged in the migratory channel; in addition, the present invention also discloses a corresponding buffer method; the present invention can reduce the potential energy of floods and reduce the impact on The impact force caused by the fish can effectively avoid the phenomenon that the fish in the fishway are easily injured by the violent impact of the flood when the sluice dam discharges the flood, and has a high protection effect on the fish.

Description

technical field [0001] The invention relates to the technical field of fishway design, in particular to a buffer fishway and a buffering method suitable for emergency flood discharge with reduced damage. Background technique [0002] The design of the fish pass mainly considers the upward habit of fish. Downstream of the dam, fish often rely on the attraction of the current to enter the fishway. In the fish pass, the fish swim upstream to overcome the current flow by their own strength. The fish pass is composed of inlet, tank body, outlet and fish-baiting water supply system. The inlet is mostly arranged on the bank or power station with stable water flow and a certain water depth, near the outlet of the overflow dam. The cross-section of the commonly used tank body is rectangular, and the water level difference between the upstream and downstream of the tank is divided into several small steps by the partition plate. excess energy. Due to the different hole shapes, it...
