[0002] The water environment refers to the spatial environment in which water is formed, distributed and transformed in nature. It is the space surrounding human populations and water bodies that can directly or indirectly affect human life and development, and the overall natural factors and related social factors for their normal functions. Some also refer to the relatively stable environment of natural waters bounded by land.

[0003] At present, in the process of water environment management, it is often necessary to sample the water first, and the existing sampling devices usually use water pumps and suction pipes to extract water from the river, and by controlling the depth of the suction pipe entering the river, water samples of different depths can be extracted. However, in actual use, since the port of the suction pipe is often open, it is inevitable that more water of different depths will flow in during the process of entering the river. As a result, when extracting samples of a specified depth, other water bodies are easily mixed in, resulting in inaccurate sampling, which greatly affects the subsequent test results.
