Abstract
A kind of test fish of the utility model belong to the ecological environmental protection test field in hydraulic engineering to the swimming pipe of dissolved gas tolerance degree.Including：Power device and main pipeline.The utility model advantage is 1, can control different in flow rate, the individually Burden-Swimming Ability of KM test of progress fish；2, it can also be arranged in sealing flume, the measurement tolerance of fish to supersaturated dissolved gas water body in specific flow velocity；3, the activity condition of test fish can be preferably observed excessively；4, since the effect present apparatus of water inlet rectification grid and water outlet rectification grid and tap hole, equal scoreboard can cut down rotating flow caused by propeller.
Description
Technical field
The utility model relates to one kind to be used for Fish Swimming Traces pipeline, its trip can be especially tested while Fish Swimming Traces
The test pipe of the characteristics such as swimming ability and dissolved gas tolerance, belongs to pilot fish field.
Background technique
Gas diseases are a kind of diseases that fish physiological damage is caused due to physical cause.Mainly due to gas in water
Divide summation and more than fish damage or the disease of death caused by atmospheric pressure, that is, gas supersaturation.
Gas downstream supersaturation problem caused by dam flood-discharge is one of the important content of aquatile environmental evaluation.It is right
For the construction of hydropower stations, the central point of concern is that influence of the supersaturated gas dissolved in water for fish, supersaturation are molten
Solution gas itself will not cause damages to environment, it is contemplated that the practicability of power station flood discharge environmental evaluation, to fish to molten
It is very necessary that the tolerance for solving the water body of supersaturated gas, which carries out further investigation,.
Existing test fish lack the requisite measure for promoting Fish Swimming Traces to the device of dissolved gas tolerance.Fish exist
Water body activity without flow velocity, does not swim substantially, swimming shape of the fish in current water under test result and native state
State is very different.
The section of common Fish Swimming Traces device experiment device is usually rectangle, but rectangular section is asked there are following
Topic：1) rectangle edge flow velocity is lower, cannot be uniformly distributed on tunneling boring；
2) when having carried out pressure swimming test, rectangular cross section Stress non-homogeneity be easy to cause device to damage, it is difficult in high pressure
It is tested under state.
Utility model content
The purpose of this utility model is to provide a kind of test fish to the swimming pipe of dissolved gas tolerance degree, with simulation
The water body of supersaturated gas is dissolved under natural flowing water state, and the supersaturated water body of flowing water state is obtained to fish by this device
The influence of class.
The technical solution adopted in the utility model is as follows：
A kind of test fish include to the swimming pipe of dissolved gas tolerance degree：Power device and main pipeline,
The power device includes：Controller, motor, electric machine main shaft, spindle carrier, propeller；
The motor is submersible machine, is connected with each other with controller by signal cable and power cable, controller
Power and control signal are provided for motor；
Electric machine main shaft is fixed on spindle carrier by bearing, and propeller is fixed on electric machine main shaft；
The main pipeline includes：End plate, equal scoreboard, water inlet flow straightening grid, flow velocity measured hole, is set main pipeline diffluence pass
Fish hole, water outlet flow straightening grid；
The motor is fixed on end plate；
The main pipeline is that diameter is not less than 20cm, the organic glass round tube of wall thickness 2cm；
The main pipeline diffluence pass is four holes opened on main pipeline by proximal plate side；
Its arrangement on main pipeline is：1) on main pipeline, aperture is being set as at end plate 2cm close to end
The boundary of plate side；2) centered on the center of circle of main pipeline section, perimeter is divided into 4 parts, is uniformly arranged four apertures；3) aperture is another
Side boundary influences the flow induced vibration of spindle carrier with reducing the length of electric machine main shaft, and reducing away from spindle carrier 2cm；4)
Its total open area is 2 times of main pipeline section area, and hole shape is round or round rectangle, to guarantee its preferable fluidised form
With compared with low flow velocity.
Specifically, the benefit of the utility model is as follows：
1, different in flow rate, the individually Burden-Swimming Ability of KM test of progress fish can be controlled；
2, can also be arranged in sealing flume, measurement in specific flow velocity fish to supersaturated dissolved gas water body
Tolerance；
3, the activity condition of test fish can be preferably observed excessively；
4, since the effect present apparatus of water inlet rectification grid and water outlet rectification grid and tap hole, equal scoreboard can cut down spiral shell
Revolve rotating flow caused by paddle.
