[0002] Groundwater refers to the water that exists in the pores, cracks and caves of rocks and soil below the earth's surface. It is one of the important freshwater resources on the earth. Groundwater is often the main source of local water supply. Groundwater quality monitoring requires regular sampling of groundwater quality in order to timely understand the pollution status of groundwater. At present, groundwater sampling is usually done after drilling a hole at the sampling point. The operator puts the sampling tube into the borehole to pump out the groundwater. When sampling groundwater, due to the complex sampling environment and the difficulty in controlling it, when the sampling tube sinks to absorb water, the water suction port may be blocked by foreign matter in the underground environment, and the purity of the sampled water cannot be guaranteed, and the sampling efficiency cannot be guaranteed.
