[0002] As we all know, in the fields of environmental monitoring and water resources research, the detection and analysis of groundwater is of vital importance. Traditional groundwater sampling methods have many limitations. For example, the sampling depth is limited, making it difficult to obtain accurate samples from different aquifers; the sampling process is easily affected by surface pollution, resulting in reduced sample accuracy; some devices are complicated to operate, have high professional requirements for sampling personnel and are inefficient. The emergence of groundwater sampling and detection devices has effectively solved these problems. It uses a special sealing and filtering structure to avoid pollution and accurately sample in layers. It is equipped with automated control components, can be remotely operated and monitored in real time, and is convenient and efficient to operate, which has effectively promoted the development of groundwater-related research and environmental assessment work.

[0003] In the prior art, it is necessary to take water samples from different water layers at different depths. After taking water, the samples are uniformly placed on a rack for testing.
