Rather, these embodiments are provided so that this disclosure will be thorough and complete.
The invention discloses an intelligent test device for penaeus vannamei boone, which comprises a test module and a regulation and control module.
It should be noted that, when the hatching test of the prawn eggs is required, the temperature of the water in the test tank 101 is adjusted to the preset temperature required by the test through the water temperature adjusting and controlling component, and the oxygen concentration of the water in the test tank 101 is adjusted to the preset concentration required by the test through the oxygen concentration adjusting and controlling component; then, the shrimp eggs are put into the water body of the test groove 101, the first driving motor 202 is controlled to drive the power plate 209 to move, so that the shrimp eggs are continuously incubated around the annular test flow channel 105 along with the flowing water body in a flowing mode, after the incubation time is up, the first driving motor 202 is controlled to stop working, the water body in the test box is in a static state, the incubation condition of the shrimp eggs is observed and recorded, and therefore the incubation rate data of the shrimp eggs under a certain water turbulence intensity is obtained, and the test process is completed.
As shown in fig. 1, 2, and 3, the test module includes a test tank 101 and a support frame 102, the test tank 101 includes a first annular tank wall 103 and a second annular tank wall 104, an annular test flow channel 105 is formed between the first annular tank wall 103 and the second annular tank wall 104, a first mounting plate 106 and a second mounting plate 107 are provided on the support frame 102, a driving turntable 108 is rotatably connected to the first mounting plate 106, a driven turntable 109 is rotatably connected to the second mounting plate 107, the driving turntable 108 and the driven turntable 109 are cooperatively connected through a rotation belt 201, a first driving motor 202 is further provided on the first mounting plate 106, an output end of the first driving motor 202 is cooperatively connected to a rotation shaft, and the rotation shaft is cooperatively connected to the driving turntable 108.
It should be noted that the first annular groove wall 103 and the second annular groove wall 104 are both made of transparent glass, so that observation and recording during testing are facilitated, and test data can be obtained more quickly.
As shown in fig. 6, 7 and 8, the supporting frame 102 is further provided with an annular guide rail 203, the annular guide rail 203 is slidably connected with at least two sets of sliding assemblies 204, each sliding assembly 204 includes a sliding block 205, two sides of the sliding block 205 are rotatably connected with sliding wheels 206, the sliding wheel 206 on one side is slidably connected with the inner side wall of the annular guide rail 203, the sliding wheel 206 on the other side is slidably connected with the outer side wall of the annular guide rail 203, the sliding block 205 is further provided with a connecting block 207, and the connecting block 207 is fixedly connected with the rotating belt 201.
Fixedly connected with connecting rod 208 on the sliding block 205, connecting rod 208 fixedly connected with power board 209, a plurality of S-shaped through-holes 301 have been seted up on the power board 209, just the power board 209 stretches into in the cyclic annular test runner 105.
It should be noted that the first driving motor 202 drives the power plate 209 to move, so as to adjust the turbulence amount of the water body in the test tank 101, and thus the water body obtains different turbulence intensities. Specifically, after the first driving motor 202 is driven, the first driving motor 202 drives the rotating shaft to rotate, so as to drive the driving turntable 108 to rotate, so that the driving turntable 108 drives the rotating belt 201 to rotate, so that the rotating belt 201 can rotate continuously around the driving turntable 108 and the driven turntable, and during the rotation of the rotating belt 201, the sliding block 205 can be driven to slide along the annular guide rail 203, and during the sliding of the sliding block 205 along the annular guide rail 203, the sliding block 205 can guide and limit the sliding block 205 through the guide wheel, so as to improve the reliability of the sliding block 205 during the sliding process, and during the sliding of the sliding block 205 along the annular guide rail 203, the sliding block 205 can drive the connecting rod 208 and the power plate 209 to move, so that the power plate 209 moves around the annular test runner 105, and during the movement of the power plate 209 around the annular test runner 105, the water in the test trough 101 can be stirred, so that the water in the test trough 101 can continuously flow around the annular test runner 105, so that the turbulent flow rate of the water in the test trough 101 can be adjusted, and when different turbulent flow intensities are required for the incubation tests, so that the water flow can be controlled, and the intelligent incubation test can be suitable for controlling the water flow speed of the water flow, so that the water flow can be controlled. In addition, the test device pushes the water body through the power plate 209, so that the water body has different turbulent flow rates, and compared with the traditional device for preparing turbulent flow through a water pump, the test device can reduce the damage of the prawn eggs to a great extent, and further improve the test precision and reliability.
It should be noted that, a plurality of S-shaped through holes 301 are formed in the power plate 209 in an array, and in the process that the power plate 209 rotates around the annular test runner 105, part of the water in the test tank 101 can flow through the S-shaped through holes 301, so that the turbulence difference degree of the water at the front and rear area positions of the power plate 209 is reduced, the water environment at the front and rear positions of the power plate 209 and the water at the rest area positions of the test tank 101 are more consistent, and the incubation is more stable, and in the process that the water flows through the S-shaped through holes 301, the water can be extruded with each other, and a high-flow-rate spiral water flow is formed, so that the disturbance to the water is increased, the turning degree of the shrimp eggs in the water is increased, the dispersion degree of the shrimp eggs is improved, and the local oxygen deficiency condition caused by the tight accumulation of the shrimp eggs is avoided.
As shown in fig. 4 and 5, the regulation and control module includes a regulation and control groove 302, the regulation and control groove 302 is disposed below the test groove 101, the regulation and control groove 302 is separated from the test groove 101 by a partition plate 303, a plurality of through holes 304 are formed in the partition plate 303, and a gauze is disposed on the through holes 304.
It should be noted that the test tank 101 and the regulation and control tank 302 are separated by a partition plate 303, and the partition plate 303 is provided with a plurality of through-flow holes 304, so that the water in the test tank 101 can flow through the water in the regulation and control tank 302, and the temperature of the water in the test tank 101 can be regulated when the water passes through the temperature of the water in the regulation and control tank 302; similarly, the concentration of oxygen in the water in the test chamber 101 can be adjusted by adjusting the concentration of oxygen in the water in the control chamber 302. Furthermore, a gauze is provided on each through-flow opening 304, so that shrimp eggs can be prevented from falling down through the through-flow openings 304 into the adjustment groove 302.
It should be noted that, the purpose of setting the partition plate 303 is also to avoid that when the oxygen concentration in the water body is regulated and controlled by the oxygen concentration regulation and control assembly, the water body oscillation in the regulation and control groove 302 affects the turbulence intensity of the water body in the test groove 101, thereby affecting the reliability of the test data, because in the process that two high-speed fluids in the regulation and control groove 302 collide with each other, the water body in the regulation and control groove 302 oscillates to a certain extent, and the setting of the partition plate 303 can limit the oscillation wave generated by the oscillation water body to enter the test groove 101 to a certain extent, thereby reducing the influence of the oscillation water body on the test when the oxygen concentration is regulated, and further improving the reliability of the test data.
