The water inlet valve is arranged at the water inlet to allow water to flow in, and is controlled by the controller through the control line to adjust the pressure difference inside and outside the detection cabin, so that the water pressure in the detection cabin is kept constant.
The water outlet valve is arranged at the water outlet and comprises a water outlet pump, and the water outlet pump is controlled by the controller through a control line and pumps water out of the detection cabin.
The controller is installed in the detection cabin, the inner hydraulic pressure meter and the outer hydraulic pressure meter are installed on the controller, the pressure in the detection cabin is detected, and the detection end of the outer hydraulic pressure meter is located outside the detection cabin and used for detecting the pressure outside the detection cabin.
The controller is connected with the water inlet valve and the water outlet valve through control lines and receives upper layer signals through signal lines. The controller controls the water inlet valve to adjust the pressure difference between the inside and the outside of the detection cabin according to the pressure difference between the inside and the outside, so that the water pressure in the detection cabin is stable, and the controller controls the water outlet valve to change water according to an upper layer signal.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The detection chamber 7 is a cylindrical chamber body.
The water inlet 10 and the water outlet 5 are positioned at two ends of the detection cabin 7.
The water outlet valve 6 is arranged at the water outlet 5, and the water inlet valve 9 is arranged at the water inlet 10.
The controller 2 is installed in detecting the cabin 7, and outer hydrostatic gage 12 and interior hydrostatic gage 3 are installed on controller 2, and outer hydrostatic gage 12 sense terminal is located outside detecting the cabin 7, and interior hydrostatic gage 3 sense terminal is located and detects the cabin 7.
The water quality sensor installation position 8 is positioned in the detection cabin 7.
The controller 2 receives the upper layer signal through the signal line 1 to generate a water changing control signal, and controls the water outlet pump 64 to work through the water changing control line 4. The controller 2 generates a differential pressure control signal according to the data of the inner water pressure gauge 3 and the outer water pressure gauge 12, and controls the operation of the stepping motor 93 through a differential pressure control line 11.
The outlet valve 6 is cylindrical, wherein the outlet plug 62 is conical, and is pressed by the return spring 63, and the outlet pump 64 is controlled by the controller 2 through the water change control line 4. When the detection chamber 7 does not change water, the water outlet pump 64 is stopped, the conical surface of the water outlet plug 62 is attached to the valve body, and the water outlet channel 61 is closed. When the detection chamber 7 changes water, the water outlet pump 64 works, the water outlet plug 62 moves rightwards, the water outlet channel 61 is opened, and water flows out of the detection chamber 7.
The water inlet valve 9 is cylindrical, wherein the water inlet plug 91 is a cone, the differential pressure spring 96 is arranged between the water inlet plug 91 and the pressure spring plate 95, the pressure spring plate 95 is fixed with the lead screw 94, and the lead screw 94 is driven by the stepping motor 93 to move left and right. The stepping motor 93 is controlled by the controller 2 through a differential pressure control line 11, the left and right movement of the screw 94 drives the pressure of the differential pressure spring 96 to change, and the pressure acts on the water inlet plug 91, so that the pressure outside the cabin acting on the water inlet plug 91 is equal to the sum of the pressure in the cabin and the pressure of the spring. When the detection cabin 7 does not change water, the conical surface of the water inlet plug 91 is attached to the valve body. When the detection chamber 7 is changed with water, the water outlet pump 64 works to reduce the pressure in the detection chamber 7, the water inlet plug 91 is opened, and water flows into the detection chamber 7 through the water inlet channel 92.
The water outlet valve 6 and the water inlet valve 9 are one-way valves, and are automatically opened when water is changed and automatically closed when the water is changed.
