Abstract
Description
TECHNICAL FIELD

[0002] Water sampling refers to the process of collecting water samples from rivers, lakes, oceans, reservoirs, or other water bodies for the purpose of assessing, monitoring, or researching the quality and characteristics of the water body. This step is crucial in various fields such as environmental science, water resource management, ecological conservation, and public health. When sampling, it is essential to ensure representativeness, meaning that the water sample taken should accurately reflect the overall condition of the water body. Typically, this involves determining appropriate sampling points, depths, times, and frequencies, and using clean, uncontaminated containers for collection.
[0003] The existing water quality monitoring sampler has certain limitations in technology, mainly manifested as being able to rely on water pressure to passively squeeze the water body into the collection tank, thereby completing the collection of water samples. However, this passive sampling method is not effective when facing the sediments at the bottom of the water body. Since the sediments are often heavier due to their own weight, they are difficult to collect by simply using water pressure. However, the pollutants contained in these sediments also have an impact on the overall water quality. Therefore, there is still room for improvement in the structure of the existing water quality monitoring sampler. SUMMARY
