Description
Technical field
The utility model is related to hydraulic engineering field, especially a kind of fish pass import moisturizing attracting experimental trough.
Background technology
In this year, with dam, the connectivity of the construction on weir and sluice, river is destroyed.The stock of fish is reduced year by year,
River ecosystem is resulted in go wrong.Therefore in order to protect the integrality of river ecosystem, more and more water conservancy projects to set
Meter persons propose to build the stabilization of the fish migration path protection stock of fish.In China in the dam built, to have many
Engineering have begun or be completed fish migration channel.For example, the Cui Jia battalion power station built up on Han River, using tabula
Board-like fish pass, finds that its effect is fine in crossing fish monitoring to it, and a good example is provided for country's fish pass construction.?
In the construction on the two river mouth power station dams Deng Gao of Yalongjiang River, dam was helped using fish lift etc., some smaller engineerings will also start
Fish migration is helped using fish pass structures such as fish locks.As helping fish to cross the important component on dam, but most fish
The effect is unsatisfactory in road Practical Project.The main reason is that the effect is unsatisfactory for the attraction of fish pass import, cause fish on dam
Under get lost, reduce fish pass import cross fish efficiency, keep the operational effect of entire fish pass undesirable.
The reason that fish pass import attracts the efficiency of effect undesirable, which is mainly fish pass import, does not have suitable attracting flow to have
Close, this is related with the flow of fish pass entrance with the complex flowfield under dam, so often designed in Practical Project one it is auxiliary
Help water system（Auxiliary water system）To provide additional flow or setting individually attraction for fish pass import
Stream（Attraction flow）The attraction effect for reinforcing fish pass import, improved fish efficiency.Therefore understand fish pass inlet flow rate with
The correlation of refill flow and influence set transformation and its transformation side of the individual attracting flow to micro flow field under dam
Formula attracts fish pass import the quality of influential effect, is the emphasis that fish pass workers study from now on.Existing document proposes at present
Above both of which promotes the attraction effect of fish pass import.Although domestic and foreign scholars did largely fish pass import
Research, but assist probing into for water charging system less in fish pass, just from the point of view of current research, only know and use this in engineering
Method can improve the success rate of fish pass import, all be supported without detailed experiment to its principle.Currently, laboratory and field
It tests to probe into its moisturizing form and does not form corresponding ripe research system and experimental program, especially attracting flow and fish
The experiment of road import, most of at present is all to use for reference Practical Project generally to change fish pass import, and come with some shortcomings place on the whole：
1, in recent years, it although fish pass import attracting flow is increasingly paid close attention to by vast fish pass builder, individually lures
The research of the moisturizing form in fish channel is still weak link.
2, the channel of fish pass import moisturizing, at present build in be rarely employed, reason with the independent benefit to fish pass import
The principles such as water form are not known.Although there is engineering experience foundation on the spot, for different engineering geological conditions, different fishes
Type, create flow field effect have significant limitation, can not effectively promote.
3, it tests on the spot there are certain risk and uncertainty, the form of moisturizing, fish pass goes out stream with different downstreams
Water level conditions have apparent difference, and the then measurement of the hydraulic indexes such as measurement of dam Fluid field has certain difficulty and wind
Danger, and put fish and test limited and technological means and fund etc., it is difficult to carry out prototype experiment in laboratory.
4, laboratory experiment is tested, maximum problem can only select stock of fish amount nearby in the selection with fish species.And
The rare stock of fish in prolonged transportational process it is difficult to ensure that keep its vigor, and in the experiment fingerling in laboratory due to life
Dis environment etc. can not survive, and secondary injury is carried out to stock of fish amount.So being tested in laboratory, if not nearby
The stock of fish, can cause prodigious experimental error, experimental provision applicability that can have a greatly reduced quality.
