Abstract
The utility model belongs to hydraulic engineering construction field, more particularly to a kind of barrage dam with fish migration channel, including on dam body and dam body fish pass import and fishway exit, wherein, the inside of dam body is equipped with the first rest pond and the second rest pond, it is respectively connected with fish pass between fish pass import and the first rest pond, between the first rest pond and the second rest pond and between the second rest pond and fishway exit, is staggeredly distributed with several spoilers on the two sidewalls of each fish pass.Barrage dam described in the utility model with fish migration channel, the fish pass equipped with three-stage, and spoiler is equipped in fish pass, the tilt angle of fish pass is not only reduced, energy dissipating path is also added, keeps water flow slower；In addition, being equipped with the first rest pond and the second rest pond, takes a break for straddling fish stocks, effectively increase the migration success rate of fish, protect the ecological balance.
Description
Technical field
The utility model relates to a kind of barrage dams with fish migration channel, belong to hydraulic engineering construction field.
Background technique
Barrage dam is called rubber dam, is that a seat tool has flood control, irrigates, regulates and stores, generating electricity, supplying water and tourism development etc. is more
The water-control project of kind function, the setting of barrage dam have blocked fish and other certain species by the breeding offspring that migrates
The migration path of (such as white fine jade globefish), seriously affects the breeding of fish, is unfavorable for the ecological balance.For this purpose, some barrage dams are usual
Equipped with fish migration channel, still, the fish migration channel design that existing barrage dam is equipped with is unreasonable, in fish migration channel
Water velocity is too fast, and straddling fish stocks can not sail against the current, and hinders fish reproduction.
Utility model content
According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: providing a kind of structure letter
It is single reasonable, convenient for the barrage dam with fish migration channel of fish success migration.
Barrage dam described in the utility model with fish migration channel, including the fish pass import on dam body and dam body
With fishway exit, wherein the inside of dam body is equipped with the first rest pond and the second rest pond, fish pass import and the first rest pond it
Between, be respectively connected with fish pass, each fish pass between the first rest pond and the second rest pond and between the second rest pond and fishway exit
Two sidewalls on be staggeredly distributed with several spoilers.
Above-mentioned spoiler is " V " type, and a straight-arm of spoiler is fixed on the side wall of fish pass, another straight-arm of spoiler
It is deflected to water flow opposite direction, can not only play the role of slowing down water flow, but also can play the guiding role to fish migration.
Angle between two straight-arms of above-mentioned spoiler is 120 °~150 °, has higher success rate fish migration.
Possessed beneficial effect is the utility model compared with prior art:
Barrage dam described in the utility model with fish migration channel, the fish pass equipped with three-stage, and in fish pass
It is interior to be equipped with spoiler, the tilt angle of fish pass is not only reduced, energy dissipating path is also added, keeps water flow slower；In addition, being equipped with
First rest pond and the second rest pond, take a break for straddling fish stocks, effectively increase the migration success rate of fish, protect
The ecological balance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the overlooking structure diagram of fish pass in Fig. 1.
In figure: 1, fish pass import；2, fish pass；3, the second rest pond；4, dam body；5, fishway exit；6, the first rest pond；7,
Spoiler.
Specific embodiment
The embodiments of the present invention are described further with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, the barrage dam described in the utility model with fish migration channel, including 4 He of dam body
Fish pass import 1 and fishway exit 5 on dam body 4, wherein the inside of dam body 4 is equipped with the first rest pond 6 and the second rest pond 3, fish
Between road import 1 and the first rest pond 6, between the first rest pond 6 and the second rest pond 3 and the second rest pond 3 goes out with fish pass
It is respectively connected with fish pass 2 between mouth 5, several spoilers 7 are staggeredly distributed on the two sidewalls of each fish pass 2.
In preferred embodiment: spoiler 7 is " V " type, and a straight-arm of spoiler 7 is fixed on the side wall of fish pass 2, spoiler
7 another straight-arm is deflected to water flow opposite direction, can not only play the role of slowing down water flow, but also can play the guiding role to fish migration；
Angle between two straight-arms of spoiler 7 is 120 °~150 °, has higher success rate fish migration.
Barrage dam described in the utility model with fish migration channel, the fish pass 2 equipped with three-stage, and in fish pass
It is equipped with spoiler 7 in 2, not only reduces the tilt angle of fish pass 2, also adds energy dissipating path, keep water flow slower, make fish
Migration is more smooth；In addition, being equipped with the first rest pond 6 and the second rest pond 3, takes a break and turn to for straddling fish stocks, effectively
The migration success rate for improving fish, protects the ecological balance.
