  • Patent number: 12221758
    Abstract: The present disclosure discloses a buffering fishway suitable for emergent flood discharge with reduction in damage and a buffering method thereof. The buffering fishway includes a fishway body, wherein a migration passage is arranged inside the fishway body, one end of which is rotationally connected with a fixing base, and the other end of which is rotationally connected with a counterweighting floating dock, and a plurality of buffering plates capable of swinging are hinged inside the migration passage, furthermore, the present disclosure also provides a buffering method corresponding to it. The present disclosure effectively reduces the potential energy of the flood and weakens the impact force on the fish. Therefore, the gate dam having this design effectively avoids the fish in the fishway from being fiercely impacted by the flood and easily resulting in damage during discharging flood, having a high protective effect on the fish.

  • Publication number: 20240183120
    Abstract: Disclosed are a step-by-step paired and up-down reciprocating combined fishway and a fish passage method thereof, belonging to the technical field of fish passage facilities. The present disclosure aims to provide an efficient fish passage technology for a low-head water control project, which overcomes the defects of long construction length and low fish passage efficiency of the traditional fishway. The present disclosure includes several fishway units, a mechanical transmission system, a fish repelling system, a control system, and a recovery cableway. Under the combined action of the mechanical transmission system and the fish repelling system, the fishway units reciprocate up and down step by step to form a fish passage way. The weight of the fishway units is balanced through the rotation of coaxial eccentric wheels, and the energy consumption of the mechanical transmission system is reduced.
