The working principle of the invention is briefly described as follows:
Before the test starts, the vacuum pump 23 and the air compressor 33 are used for vacuumizing or pressurizing the connected vacuum air storage tank 22 and pressure air storage tank 32 to meet the test requirement; the test observation tank 12 is filled with water, so that the water level in the test observation tank 12 is kept level with the water level in the bottom of the pressure regulating box 45; the fish is placed in the net bag 17 and put into the full water test observation tank 12, and the upper part of the net bag 17 is fixed on the hook 18 and then the tank body is sealed by bolts.
During the test, corresponding electric valve is opened according to the pressure demand, and the purpose of adjusting the pressure in the test observation tank 12 is realized by adjusting the pressure in the pressure adjusting box 45 communicated with the test observation tank 12, and simultaneously, video and image recording is carried out on fish in the tank, so as to observe corresponding physiological characteristics. The pressure in the test observation tank 12 is regulated by opening or closing the electric valves 41 to 43, specifically, when in pressurization, the high-pressure operation safety ball valve 35 and the pressure regulation electric valve 43 are opened, the vacuum regulation electric valve 41 and the exhaust electric valve 42 are closed, the pressure regulating valve 44 is regulated to a target pressure value, so that high-pressure air in the high-pressure air storage system 3 enters the pressure regulating box 45 through the third pressure regulating pipeline, the liquid level in the pressure regulating box 45 is reduced, and the pressure of the test observation tank 12 is increased; when the pressure is reduced, the exhaust electric valve 42 and the pressure regulating electric valve 43 are closed, the vacuum operation safety ball valve 25 and the vacuum regulating electric valve 41 are opened, air in the pressure regulating box 45 enters the vacuum air storage tank 22 through the first pressure regulating pipeline, the liquid level in the pressure regulating box 45 is increased, and then the pressure of the test observation tank 12 is reduced.
Due to the pressure regulating box 45, when the test simulating the alternating change of the high pressure and the vacuum in the water machine is performed, the quick change of the pressure in the test observation tank 12 can be realized by quickly switching the opening and closing states of the electric valves 41 to 43 corresponding to the regulating pressure and the vacuum.
After the test, the exhaust electric valve 42 is opened to discharge pressure, the sealing cover 13 is opened, and the net bag 17 is taken out for subsequent dissection or observation. To ensure safety, it is necessary to close the vacuum reservoir vacuum control ball valve 24 and the pressure reservoir pressure control ball valve 34 and open the re-compression ball valve 26 and the exhaust valve 36 after each test is completed.
During or after the test, the liquid product in the vacuum tank 22 and the pressure tank 32 can be discharged by opening the drain valves 27 and 37. Wherein, the hydrops is due to: 1. the air contains moisture, the liquid volume can be formed in the pressurizing or vacuumizing process and is left at the bottom of the tank, and a drain valve is opened to remove accumulated liquid so as to avoid influencing the effective volume and the vacuum degree in the tank; 2. in the test process, water in the observation tank can be pumped or pressed into the pipeline and then enter the vacuum tank or the pressure tank, and the effective volume is also prevented from being influenced by effusion, so that the water needs to be removed in time after the test.
The foregoing embodiments are only for illustrating the present invention, and the structures, connection manners of the corresponding components may be changed, and all equivalent changes and modifications performed on the basis of the technical solutions of the present invention should not be excluded from the protection scope of the present invention.
