Description
Technical field
The utility model belongs to hydraulic engineering field, more particularly to a kind of sink for field fish pass import experiment.
Background technology
The hydraulic structures such as dam, sluice are built, and have been blocked the connectivity in river, have been led to aquatic life habitat and life
Habit living changes, cannot be from root although the progress of the engineerings such as enhancement releasing protects the quantity of some straddling fish stocks
The destruction for alleviating fish pass resource in sheet, has document proposition, the most place of fish collection is still under Ge Zhou Ba dam.Therefore, it repaiies
Fish pass and fish lift etc. are built to help fish migration be the indispensable part of hydraulic engineering from now on.But research table in recent years
Bright, the operational effect of domestic fish pass is not obvious, the reason is that China's fish pass excessively indiscriminately imitates external fish pass design, Wu Fayu
The Burden-Swimming Ability of KM of domestic fingerling is combined.Hair dawn is in the present situation to Chinese fish pass import, the problem of analyzing fish pass import, fish
The attraction rate of road import is not enough the main reason for effect is poor, this is related with the fluidised form of fish pass import.Many fish pass are built in recent years
If person starts to study the water conservancy characteristic of fish pass import, Zheng Tiegang simulates dam Fluid field, analysis using FLOW-3D softwares
Select the position of fish pass import.Gong Li is analyzed with laboratory experiment sink for the fish pass import with migratory fish grass carp
Optimum flow rate is 0.3.
Since fish are very sensitive to flow, fish pass import water conservancy characteristic, such as flow velocity, tubulence energy, turbulence intensity pair are understood
Fish enter the influence of fish pass, fish can be enable to understand and differentiated with the flow condition for generating suitable fish under dam and tracing back
Where the position of fish pass import and it can smoothly enter in fish pass or in fish gathering channel.
In order to understand the hydraulic characteristic of fish pass import, observation fish are traced back in the track that fish pass import is traced back, and fish are analyzed
The preference hydraulics factor traced back.Fish pass entrance location location problem is solved therefore it is necessary to largely test, at present with regard to fish
Road import experiment, generally there are problems with：
（1）Mainly based on prototype on the spot and laboratory hydraulic model, that tests on the spot lacks for experiment both domestic and external at present
Be trapped in it is affected by environment larger, dam Fluid field is complex, is not easy to measure and there are certain danger.In laboratory
Hydraulic model is carried out main problem is that the difference of regional disparity, wild fingerling and cultivation is very big, in addition the fingerling in China
Large number of, inter-individual difference is very big, as the Burden-Swimming Ability of KM of the crack fish of Tibet region it is common compared to the Changjiang river four everybody
Its Burden-Swimming Ability of KM is eager to excel many for fish, and being directed to different fishes, we need different flow velocity operating modes is arranged and test.
（2）Some experiment in, in order to solve the problems, such as fingerling, using the equipment such as fish transportation vehicle by fish be transported in laboratory into
Row experiment, but according at present for, first the reason is that the cost of fish transportation vehicle is higher, the second chief reason also has its process pair
It is there is a great harm for fish and irreversible, it is easy to influence the accuracy of experimental result.
（3）For building facility in the wild, at present for, generally use concrete experiments device, defect Preparatory work of experiment
Time is longer, and quantities is larger, occupation of land face it is larger and also its experiment after can not move, dismounting it is complex.
