Description
Technical Field
The utility model relates to an import and export layer-stepping fishway belongs to ecological hydraulic structure technical field among the hydraulic and hydroelectric engineering.
Background
According to the existing fishway research, due to the influence of water diversion and water regulation or power generation in hydraulic engineering, the water level at the downstream of the dam site is actually in a constantly changing state, and researchers generally select a proper traditional fishway inlet according to the downstream water level variation and fish preference. However, in actual work, the selection of fishway inlets is limited by the variation of water level, and inlets with different working elevations have to be arranged, so that the actual selection of the inlets does not accord with the preference of fishes, and multiple problems of overlarge fishway floor area, high operation management cost and the like caused by a plurality of inlets generate certain adverse effects on the development of the fishway industry.
In the prior art, chinese patent publication No. CN204370386U discloses a dam fishway structure, which proposes to arrange fishways in layers on a dam, but does not improve the most critical design link of a fishway, namely "fish luring import".
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an import and export layer-stepping fishway.
The utility model discloses a following technical scheme can realize.
The utility model provides an entrance and exit layered fishway, which comprises a fishway; the fishway is divided into a plurality of layers of sub fishways, and each layer of sub fishways are arranged in parallel; one end of the sub-fishway is an outlet, and the other end of the sub-fishway is an inlet; the inlets of the sub-fishways are respectively provided with a spraying water pipe; the interior of the fishway is a fishway pool chamber, and fishway clapboards and fishway piers are longitudinally and alternately arranged on the inner walls of two sides of the fishway pool chamber.
The fishway is integrally of a concrete structure.
The water spraying pipes are respectively vertically arranged on the inner walls of the two sides of the entrance of the sub fishway.
The outlets of the plurality of layers of the sub-fishways are positioned on the same side, and the inlets are positioned on the other side.
