Title:
STEPPED, PAIRED VERTICALLY RECIPROCATING COMBINED TYPE FISHWAY AND FISH PASSAGE METHOD
Document Type and Number:
WIPO Patent Application WO/2023/169428
Kind Code:
A1
Abstract:
Disclosed are a stepwise paired vertically reciprocating combined type fishway, and a fish passage method, relating to the technical field of fish passage infrastructure. The present invention aims to provide an efficient fish passage technique for a low-head water conservancy project, to overcome the shortcomings of large construction length and low fish passage efficiency in conventional fishways. The present invention comprises multiple fishway units, a mechanical transmission system, a fish driving system, a control system, and a recovery cableway. Under joint action of the mechanical transmission system and the fish driving system, the fishway units move vertically and stepwise in a reciprocating manner to form a fish passage channel. By balancing weights of the fishway units by means of rotation of coaxial eccentric wheels, the energy consumption of the mechanical transmission system is reduced; and linking of the fishway units is realized by means of embedded sliding between sliding grooves and sliding blocks, and tangential rolling between roller rows and partition plates. The present invention can reduce the length of fishway construction, saving construction costs, can effectively lower the impact of water conservancy and hydropower projects on river connectivity, has wide engineering application prospects, and has significant ecological benefits and economic benefits.
