Embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the present apparatus includes the inside that the tank 5 of periphery and poly (methyl methacrylate) plate 2 are formed with plate 15
Small tank.The rotating speed of variable-frequency motor 8 is adjusted by frequency converter 10 so that current from right to left can be produced in pipe 4 of swimming, and
The water velocity swum in pipe 4 can be adjusted by adjusting output frequency.Current pass through " W " shape deflector after being flowed out from swimming pipe 4
1, swimming pipe is reentered to tank right side flow, and by water inlet 16, forms water circulation.
Plate 15 can be slided up and down on rail plate 13, and can be taken off, the installation of convenient pipe 4 of swimming；Plate 15
Swimming pipe 4 is just blocked when being snapped down to extreme lower position, avoids it from causing position to shift due to reasons such as water impacts；It is organic
Glass plate 2 and plate 15 form internal small tank, can avoid due to the spray caused by current and ripple, and the water surface is put down in guarantee environment
It is quiet, the observation to testing fish swimming behavior can be achieved；
Swimming pipe holder 17 and the semicircular indentations for having matches mutually on plate 15, when plate 15 is snapped down to bottom, the two is just
Circular opening is formed, the circular opening diameter is identical with swimming pipe overall diameter, and swimming pipe 4 extends there through, and can fix swimming pipe
Wherein, while reduce internal small tank and exchanged with extraneous current, beneficial to the formation of the small tank Lentic environment in inside；
The rotating speed of variable-frequency motor 8 and propeller can be adjusted by adjusting the output frequency of frequency converter 10, and then adjust swimming pipe 4
Interior water velocity.Different water velocities can be produced in swimming is managed in this way；
" W " shape deflector is installed in front of the swimming delivery port of pipe 4, the water resistance of the swimming delivery port of pipe 4 can be reduced, while reduces current
The loss of kinetic energy, beneficial on the right side of flow direction tank；
The top of poly (methyl methacrylate) plate 2 is provided with opaque cover plate 3, positioned at the surface of swimming pipe, slidably and removes.Testing
During the cover plate provide sheltered situation for test fish, reduce the stress reaction during experiment fish swimming；
Being erect in the middle part of two swimming pipes has an opaque dividing plate 12, avoids the energy during swimming of the experiment fish in left and right swimming pipe
Enough see to other side, result of the test may be had an impact；
There is cystosepiment 7 top of variable-frequency motor 8, and cystosepiment 7 is located among poly (methyl methacrylate) plate 2, prevents because current cause its position
It is mobile；Cystosepiment float with the water surface, can be freely up and down movable with the height change of water level, beneficial to preventing propeller 14 at a high speed
Whirlpool is up produced during rotation, is caused in bubble suction swimming pipe 4；
The peripheral right side of tank 5 stretches out, and object disposing platform 9 is provided with, to install frequency converter 10 and put other articles；
The depth of water may influence water resistance, and change the flow velocity of swimming pipe.Therefore the water level in tank needs quantitative, by being installed on
The graduated scale 19 of tank inwall is completed；
There is discharge outlet 18 lower section of swimming pipe holder 17.When preventing water channel drain, water is internally put aside in small tank, can not be discharged；
Preceding mozzle 6 includes pore mozzle 21 and gross porosity mozzle 22, and thin stainless steel is mounted on inside two kinds of mozzles
Piece forms lattice, and the lattice in gross porosity mozzle 22 is bigger, passes through the secondary guide functions of mozzle so that propeller produces
Raw rotary water current becomes steady；Pipe 4 of swimming is constant in this section of external diameter, and internal diameter becomes big, just holds mozzle 6, in mozzle 6
Footpath and swimming pipe 4 are consistent, and outer wall is close to this section swimming inside pipe wall, and the two wall thickness sum is the normal thickness of swimming pipe 4.In addition
Constantly increase in the low order end internal diameter of mozzle 6, form similar bell-mouth structure of air, reduce after mozzle 6 is installed the volume in swimming pipe 4
Water resistance caused by outer；Mozzle 6 can take out from the swimming right-hand member of pipe 4 and be cleaned or be changed；
The left end of mozzle 21 is provided with stainless steel wire inside deep swimming pipe, avoids test fish excessively close with mozzle 6.Simultaneously
Stainless steel wire end is spherical shape, avoids the injury to test fish；
The grid of stainless steel substrates composition is also installed afterwards, and right-hand member is also provided with stainless steel wire 20, prevents from trying inside mozzle 11
Test fish swimming during too close to or lean on after mozzle 11；Section swimming pipe external diameter is constant, internal diameter increase, can just hold
Mozzle 11 afterwards, the rear internal diameter of mozzle 11 is consistent with swimming pipe 4, and outer wall is close to the inwall of this section swimming pipe 4, the two wall thickness sum
For the normal thickness of pipe 4 of swimming, extra water resistance is reduced；In addition, the rear high order end 1cm of mozzle 11 length wall thickness and the phase of pipe 4 of swimming
Together, the taking-up of mozzle 11 after facilitating（Load test fish, cleaning or replacing）.
