Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see Figure 1-12 , an ecologically imitative fishway adopting natural pebble partitions, comprising a fishway partition 10 and a fishway tank body 12, the fishway tank body 12 including a vertical side wall 8, an inclined side wall 9 and a fishway floor fishway bottom plate 5. The vertical slope of the fishway is 1:135. The length of the fishway tank body 12 is 4.5m, and the maximum width is 3.85m. The height is 0.5m, one side wall is ver...

Abstract

The invention discloses a zoological-imitated fishway with a natural cobble partition plate. The zoological-imitated fishway comprises fishway partition plates and a fishway aqueduct body, wherein vertical side walls are arranged on the left sides of the fishway partition plates; inclined side walls are arranged on the right sides of the fishway partition plates; the fishway partition plates comprise cobble partition walls, long partition plates, short partition plates and longitudinal pore plates; the cobble partition walls are connected with one side of the inclined side wall; S-shaped fishthrough holes are formed in different areas at different heights of the cobble partition walls; the long partition plates are connected with the other ends of the cobble partition plates; the longitudinal pore plates are connected with one sides of the long partition plates; the long partition plates and the short partition plates are distributed in a staggered manner to form fish through verticalseams. By adopting the zoological-imitated fishway, harmonies of through fishes and fishway water flows are improved, the fish through efficiency is improved, and a nature-imitated effect is achieved; in addition, due to adoption of the 'S'-shaped fish through holes, a flow field structure similar to a through fish target swimming track line is constructed, biological characteristics of target fishes are met, and furthermore, the purpose that the flow speed of a chamber is reduced and upstream sailing of fish targets is met are achieved.

Description

technical field [0001] The invention relates to the technical field of imitation ecological fishway of Jukou gate and dam, in particular to an ecological imitation fishway adopting natural pebble partitions. Background technique [0002] Since the construction and operation of the Jukou barrage has changed the hydrological regime and fish habitat characteristics of the river section affected by the project, in order to preserve the migration channels of migratory fish and promote the communication of groups above and below the dam, the Jukou sluice hub must build imitation ecological fish habitats. The so-called fishway is an artificial passage for fish to go upstream through gates, dams and other structures or natural obstacles. The initial fishway is often to solve the problem of specific fish. It was designed and built upwards, and its typical representative is the Daniel-style fishway invented by the Belgians. Later, weir-flow fishways and vertical-slit fishways appeared...
