Abstract

A Taiji fishway structure includes fishway pool chamber units arranged sequentially along a water flow direction, each fishway pool chamber unit includes an curved side wall, an curved deflector, and a first longitudinal side wall, a fishway vertical partition plate, and a second longitudinal side wall provided on the same side of the fishway. A head end of the curved deflector of the i-th fishway pool chamber unit connects to a head end of the curved side wall in the (i+1)th fishway pool chamber unit, and forms a fish passage vertical slot that matches target fish body size with an end of the fishway vertical partition plate in the (i+1)th fishway pool chamber unit, and water flow of the i-th fishway pool chamber unit is ejected toward the curved side wall in the (i+1)th fishway pool chamber unit through the fish passage vertical slot.

A Taiji fishway structure, comprising a plurality of fishway pool chamber units arranged in sequence along a water flow direction, wherein each fishway pool chamber unit comprises an curved side wall, an curved deflector, and a first longitudinal side wall, a fishway vertical partition plate, and a second longitudinal side wall provided on the same side of the fishway, wherein:

the curved side wall is arranged on an opposite side of the second longitudinal side wall, the curved side wall is bent toward the second longitudinal side wall and extends along the water flow direction, the curved deflector is arranged on an inner side of the curved side wall, and the curved deflector is bent toward the curved side wall, the curved deflector comprises a head end and a tail end arranged opposite to each other along the water flow direction, the head end of the curved deflector is connected to a tail end of the curved side wall, and the tail end of the curved deflector extends from the head end of the curved deflector to a middle area of the fishway pool chamber;
the first longitudinal side wall is arranged upstream of the fishway vertical partition plate and extends longitudinally along a fishway, the fishway vertical partition plate is perpendicular to the first longitudinal side wall, and the second longitudinal side wall is arranged downstream of the fishway vertical partition plate and extends longitudinally along the fishway;
the head end of the curved deflector of the i-th fishway pool chamber unit is connected to the head end of the curved side wall in the (i+1)th fishway pool chamber unit, the head end of the curved deflector of the i-th fishway pool chamber unit and the end of the fishway vertical partition plate in the (i+1)th fishway pool chamber unit form a fish passage vertical slot that matches target fish body size, and water flow of the i-th fishway pool chamber unit is ejected toward the curved side wall in the (i+1)th fishway pool chamber unit through the fish passage vertical slot;
wherein i is a positive integer, i≥1.
