Description
Technical field
This utility model relates to the version of fish pass dividing plate, is specifically related to a kind of band down-the-hole vertical seam type fish channel structure.
Background technology
Water resources dam construction can provide safety that is many convenient and that protect downstream resident for the mankind, but dam is built
Many impacts that brings on local river ecological, main impact: building up of dam improves water level, has blocked river,
Fish (such as onychostoma simus, blue or green rasbora etc.) are difficult to, and fish reproduction that migration lays eggs to upstream brings adverse effect.
From the standpoint of protection Fish natural resources and improvement of the ecological environment, dam engineering is built fish pass, as ditch
One important remedial measure of logical fish migration route.At present, the Chinese utility model of Application No. 201210258999.0 is special
Profit discloses a kind of vertical seam type fish channel structure, and this structure exists some defects:
Tracing back current for ensureing that fish can be found smoothly, fish pass has certain letdown flow, can make flow velocity at the perps of room, pond
Relatively big, physical demands can be increased during fish migration, not easily pass through.
The Chinese invention patent of Application No. 201510867103.2 discloses the fish pass of a kind of band energy dissipating post, and this structure is disturbed
The disorderly current at perps so that the flow rate of water flow in fish pass reduces, reached to substantially reduce the effect of energy dissipation of resistance to water-flow,
Can pass through at perps when guaranteeing fish migration, reduce the fish consumption to muscle power during migration, improve its migration effect
Rate.
Room, pond current can only be less by other position flow velocitys from perps, there is certain backflow, easily upsets fish migration
Time sense of direction.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of the construction of existing regulating barrage engineering, it is provided that a kind of band down-the-hole erects
Seam fish channel structure.This structural adjustment flow direction, optimizes room, pond fluidised form, and can be in relatively slow the stopping of current when making fish migration
The finishing of breath room, regains one's strength of body.(we are exactly mainly to offer down-the-hole on wide partition with above-mentioned difference), down-the-hole solves and reduces
Pond indoor return situation, current are more suitable, and flow velocity is little.
For achieving the above object, a kind of band down-the-hole vertical seam type fish channel structure, described fish channel structure designed by this utility model
Including fish pass sidewall and diaphragm structure, fish pass is divided into room, multiple fishpond by described diaphragm structure, described diaphragm structure include wide every
Plate and narrow dividing plate, described wide partition is oppositely arranged with narrow dividing plate, forms stream perpendicular between the end face of described wide partition and narrow dividing plate
Seam, described wide partition is provided with the weather board contrary with water (flow) direction near crossing stream perps end, and side, described wide partition top is opened
It is connected with down-the-hole.
A progressive ground, the cross section of described down-the-hole is square structure, and they are long a width of 30～50cm x30～50cm years old.
Yet further, the length of described down-the-hole a width of 40cm x40cm.
Yet further, the spacing of described diaphragm structure is 2.5～3.0m.Room, every 10 fishponds 3 is provided with lobby, has a rest
Room length 5.0～7.0m.
Yet further, the bottom surface gradient of room, described fishpond is 1:30.
Yet further, described wide partition and narrow block board thickness are 20～30cm, shape between described wide partition and narrow dividing plate
The A/F becoming stream perps is 30～50cm, and the described angle crossing stream perps and fish pass axis is 30～45 °.
Yet further, described weather board a length of 50～55cm.Preferably, a length of 53.6cm of weather board.
The beneficial effects of the utility model:
Arrange on the dividing plate of a kind of band down-the-hole vertical seam type fish channel structure designed by this utility model that down-the-hole crosses stream, weather board is adjusted
Throttling state, makes current after room, upper level pond perps enters, continues to let out along under the trough rim wall downstream of narrow dividing plate limit, water-flow equation
More uniform, flow velocity is suitable for the medium-sized Fish such as onychostoma simus, clear rasbora and traces back, and there is area of slack water, by perps, weather board, down-the-hole
Lower sluicing stream is made to meet the requirement that Fish are traced back.Being beneficial to trace back Fish and keep muscle power, increase fish pass crosses fish effect.
