The fixed unit 1 adopts a wall-mounted design, and the main body 2 of the sampling device is suspended at the wellhead through the fixed unit 1, and its height can be adjusted as required. This design can prevent sewage from entering into the main body 5 of the sampling device and cause the structure to be corroded and damaged. The outline of the fixed unit 1 is a cylinder, which is suitable for the wellhead shapes of most waterways. Compared with other shapes, it has no edges and corners, and the force is more balanced. It has a higher safety factor and is convenient for drilling relatively narrow wellheads.

As shown in Figures 2-4, the main body 2 of the sampling device includes: a peristaltic pump 21, a sampling bucket 22, a filter unit 23, a liquid leakage sensor 24, a flow sensor 25, a liquid level sensor 26, a refrigeration unit 27, an inflammable and explosive gas Sensor 28, battery 29 and control unit. in:

The peristaltic pump 21 is equipped with a hose. One end of the hose is immersed in the sewage at the sampling point. After passing through the peristaltic pump 21, the other end is connected to the sampling bucket 22. The sewage water sample at the sampling point is sucked through the hose through the peristaltic pump 21. In the sampling bucket 22. When working, the runner of the peristaltic pump 21 will compress the flexible hose with resilience, and keep the seal before and after the pressure point. As the pressure wheel rotates, the pressure point on the hose moves accordingly. Because the hose has resilience, the hose on the inlet side of the peristaltic pump 21 naturally rebounds as the pressure wheel leaves, and negative pressure suction is generated at the inlet of the hose. liquid. With the continuous rotation of the rotor of the peristaltic pump 21 , the sewage water sample is continuously sucked into the hose and discharged into the sampling bucket 22 from the outlet side.

The sampling barrel 22 is connected to the peristaltic pump 21 through a hose, and is used for collecting sewage samples, and has good sealing performance. In this embodiment, the sampling barrel 22 is made of HDPE, which can collect 5L of water samples.

The filter device 23 provides a variety of screen mesh specifications for sampling personnel to switch according to the water quality of the sampling site.

The liquid leakage sensor 24 is located at the pump head of the peristaltic pump 21 and is used to monitor in real time whether the hose of the peristaltic pump 21 leaks. When the moment of water leakage is detected, the main body 2 of the sampling device sends an alarm in time and stops working. Sampling personnel can replace consumables in time according to the prompts of the APP software.

The flow sensor 25 is arranged on the hose connected between the peristaltic pump 21 and the sampling bucket 22, and its signal output end is connected to the input end of the control unit for real-time detection of the sewage flow in the hose.

The liquid level sensor 26 is installed at the high position of the sampling barrel 22, adopts a non-contact design, and is used for detecting the liquid level of water samples that may contain various toxic substances or acid-base sewage. When the water level of the sewage water sample in the sampling bucket 22 reaches the set threshold, the sampling device will give an alarm in real time and stop working automatically. Sampling personnel can extract or replace water samples by themselves after receiving the information through the client APP.

Open the fixed unit to form a stable wall-mounted structure, which is suspended at the wellhead, and its height can be adjusted according to the specific situation. After confirming that the sampling device is firmly fixed, monitor the data fed back by the flammable and explosive gas sensor, and carry out subsequent experiments after the data is stable. The flammable and explosive gas sensor remains open during the operation of the sampling device. Once the concentration of flammable and explosive gas in the well is sensed to exceed the threshold, the sampling device will immediately alarm and stop working.

Remotely control multiple sampling devices at the same time through the client APP, click on the number of each sampling device, you can edit the sampling point address and other specific information, you can set the parameters of sampling frequency, sampling volume, sampling times, and observe the instantaneous Flow rate, flammable and explosive gas concentration, and sample storage temperature parameters.

After passing through the peristaltic pump, the sewage finally enters the sampling bucket. The sampling device contains a flow sensor, and the system stops filtering when the sampling volume reaches the threshold set by the system. At this time, the system controls the peristaltic pump to back flush to empty all the water samples remaining in the pipeline of the instrument. While using the residual water samples in the pipeline to back wash the impurities in the filter unit screen structure, it can also ensure that the water accuracy and independence of the sample collection process.

According to the set sampling frequency parameters, the sampling device enters the static stage and suspends its work. The subsequent sampling process continues after the rest time has elapsed. Cycle in this mode until all samples have been collected.
