[0002] As we all know, water is the source of life. Human beings cannot live without water in their lives and production activities. The quality of drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Drinking water mainly considers the impact on human health. In addition to physical and chemical indicators, its water quality standards also include microbial indicators. For industrial water, whether it affects product quality or is easy to damage containers and pipes is considered.

[0003] When conducting water quality testing, a sampling device is usually required to collect samples. Since the contents of microorganisms, chemical elements, etc. in water are different at different depths in the same area of ​​water, a sampling device is required to separately sample water at different depths. However, the sampling device in the prior art is usually a simple bottle structure, and it is difficult to achieve automatic sealing when underwater, which makes it inconvenient to sample water at different depths.
