[0002] In the field of environmental monitoring, liquid contact measurement is an important and conventional monitoring method, but it also has many shortcomings. For complex environmental samples, such as samples containing multiple pollutants or unknown components, the accuracy of liquid contact measurement is difficult to guarantee, and when the liquid contact sensor is in contact with pollutants for a long time, it will age due to chemical corrosion, physical wear and other reasons, resulting in a decrease in measurement performance. There are still many technical means for monitoring liquid volatile gases on the current market, but these means often have high equipment complexity, cumbersome operation, high cost, and are difficult to adapt to the needs of continuous field monitoring. The demand for monitoring means in the field of environmental monitoring technology focuses more on continuity, convenience, and economy, which means that the ideal monitoring solution should be able to achieve real-time tracking of environmental changes, be simple and easy to operate, and keep the cost within a reasonable range to facilitate large-scale promotion and application.

The aeration component is fixedly connected to the waterproof chassis, and the aeration component is arranged inside the waterproof chassis. The blowing end of the aeration component is inserted into the detection circulation pool, and the blowing end of the aeration component is located at the bottom of the detection circulation pool. The suction end of the aeration component is threadedly connected to the detection circulation pool. The PH sensor is inserted into the detection circulation pool, and the PH sensor is threadedly connected to the detection circulation pool. The temperature sensor is inserted into the detection circulation pool, and the temperature sensor is threadedly connected to the detection circulation pool. The sample outlet valve passes through the waterproof chassis, and the sample outlet valve is threadedly connected to the detection circulation pool. The sample outlet valve is connected to the detection circulation pool, and the sample outlet valve is connected to the detection circulation pool. The sample outlet valve is located above the connecting valve, and the sample outlet valve and the connecting valve are located on both sides of the circulation pool body.

[0005] The connecting valve is normally open. When the detection device is working, the test water sample enters the filter module through the injection valve. When the flow rate of the test water sample in the injection valve is too fast, the overflow drain valve discharges part of the test water sample to ensure that the filter module will not overflow. After the test water sample is filtered by the filter module, it enters the detection flow pool through the connecting valve. The height difference between the connecting valve and the sample outlet valve forms a liquid seal cavity at the upper end of the detection flow pool. The aeration component works to extract the gas in the liquid seal cavity, and then injects it into the test water sample through the blowing end of the aeration component for aeration, so that the gas in the test water sample is released faster. The air blowing component extracts the released gas and blows it to the detection end of the monitoring sensor through the blowing end of the air blowing component, which is convenient for the monitoring sensor to monitor and prevents liquid from splashing to the monitoring port of the monitoring sensor to affect the monitoring. The PH sensor and the temperature sensor monitor the PH value and temperature of the water sample respectively, and the monitoring data are fed back to the controller in real time. Finally, the water sample is discharged by the sample outlet valve, and the controller controls the opening and closing of the filter module and the detection flow pool to achieve timed sewage discharge and cleaning.

[0006] Furthermore, the filter module includes a filter pool, a filter cover plate, a filter partition plate, a drive motor, a rotating shaft and a slag discharge valve, the filter cover plate and the filter pool are fixedly connected, a column is arranged in the filter pool, the column separates the filter pool, the column is lower than the filter cover plate, one side of the column is a filter area, the other side of the column is a filtrate area, the upper end surface of the column and the filter cover plate are a connecting area, the connecting valve is connected to the filtrate area, the connecting valve is located at the lower end part of the filtrate area, the filter partition plate is arranged between the upper end surface of the column and the lower end surface of the filter area, and the connecting valve is connected to the filtrate area.

During filtration, the drive motor starts to drive the rotating shaft to rotate, and the centrifugal force is used to accelerate the precipitation of impurities to improve the filtration efficiency. The filter partition separates the filter area. After the water sample below the filter partition is filtered by the filter partition, it undergoes secondary precipitation under the centrifugal force generated by the rotating shaft, making the water sample entering the filtrate area purer and reducing the impact of impurities on the monitoring data. The controller controls the slag discharge valve to perform regular sewage discharge and cleaning of the filter area.

The aeration component works to extract the gas in the liquid-sealed cavity, and then injects it into the test water sample through the blowing end of the aeration component for aeration, so that the gas in the test water sample is released faster. The air blowing component extracts the released gas, and then blows it to the detection end of the monitoring sensor through the blowing end of the air blowing component, which is convenient for the monitoring sensor to monitor and prevents liquid from splashing to the monitoring port of the monitoring sensor to affect the monitoring.

[0039] The circulation pool body 71 is divided into an aeration detection area 74, a pH detection area 75 and a temperature detection area 76 to prevent bubbles generated by the aeration assembly 10 during operation from affecting the monitoring accuracy of the pH value and the temperature value.

[0040] like Figure 2 and Figure 3 As shown, the air blowing assembly 9 includes an air blowing pump 91, an air blowing suction pipe 92 and an air blowing pipe 93, the air blowing pump 91 is fixedly connected to the waterproof chassis 1, the air blowing pump 91 is arranged inside the waterproof chassis 1, one end of the air blowing suction pipe 92 is fixedly connected to the air suction port of the air blowing pump 91, the other end of the air blowing suction pipe 92 is threadedly connected to the circulation pool cover 72, one end of the air blowing pipe 93 is fixedly connected to the air blowing port of the air blowing pump 91, the other end of the air blowing pipe 93 passes through the circulation pool cover 72, the air blowing pipe 93 is inserted into the aeration detection area 74, and the air blowing end of the air blowing pipe 93 faces the detection end of the monitoring sensor 8.

[0041] When the air blowing component 9 is working, the air blowing pump 91 is started, and the air blowing suction pipe 92 extracts the gas in the liquid seal cavity, and then blows it to the detection end of the monitoring sensor 8 through the air blowing pipe 93 for monitoring, thereby achieving the air blowing effect and preventing liquid from splashing to the detection end of the monitoring sensor 8 and affecting the detection effect.

[0042] like Figure 2 and Figure 3As shown, the aeration assembly 10 includes an aeration air pump 101, an aeration suction pipe 102 and an aeration pipe 103. The aeration air pump 101 is fixedly connected to the waterproof chassis 1, and the aeration air pump 101 is arranged inside the waterproof chassis 1. One end of the aeration suction pipe 102 is fixedly connected to the air suction port of the aeration air pump 101, and the other end of the aeration suction pipe 102 is threadedly connected to the circulation pool cover 72. One end of the aeration pipe 103 is fixedly connected to the air blowing port of the aeration air pump 101, and the other end of the aeration pipe 103 passes through the circulation pool cover 72.

[0043] When the aeration assembly 10 is working, the aeration air pump 101 is started, and the aeration suction pipe 102 extracts the gas in the liquid-sealed cavity, and then injects it into the water sample for aeration through the aeration pipe 103, so as to release the gas in the water sample into the liquid-sealed cavity more quickly for monitoring by the monitoring sensor 8, thereby improving the monitoring efficiency.

[0044] The working principle of the present invention is as follows: the connecting valve 6 is in a normally open state. When the detection device is working, the test water sample enters the filter area 58 through the injection valve 3. When the water sample flow rate in the injection valve 3 is too fast, the overflow drain valve 4 discharges part of the test water sample to ensure that the filter pool 51 will not overflow. During filtering, the drive motor 54 is started to drive the rotating shaft 55 to rotate, and the centrifugal force is used to accelerate the precipitation of impurities and improve the filtration efficiency. The filter partition 53 separates the filter area 58. After the water sample below the filter partition 53 is filtered by the filter partition 53, it is subjected to secondary precipitation under the centrifugal force generated by the rotating shaft 55, so that the water sample entering the filtrate area 59 is purer. The filtered water sample enters the aeration detection area 74 through the connecting valve 6, and the aeration air pump 101 is started, the aeration suction pipe 102 draws out the gas in the liquid seal cavity, and then blows it into the water sample through the aeration pipe 103 for aeration, so as to release the gas in the water sample into the liquid seal cavity more quickly. The air blowing pump 91 is started, the air blowing suction pipe 92 draws out the gas in the liquid seal cavity, and then blows it to the detection end of the monitoring sensor 8 through the blowing pipe 93 for monitoring, so as to achieve the effect of air blowing, and prevent the liquid from splashing to the detection end of the monitoring sensor 8 and affecting the detection effect. At the same time, the pH sensor 11 and the temperature sensor 12 monitor the water samples in the pH detection area 75 and the temperature detection area 76, and the monitoring data is fed back to the controller 2 in real time. The controller 2 controls the opening and closing of the slag discharge valve 56 and the liquid discharge valve 73 to realize the timed sewage discharge and cleaning.
