[0002] Water conservancy and hydropower testing is a process of comprehensive monitoring and evaluation of water conservancy projects and hydropower projects. It aims to ensure the safety, stability, and compliance of water quality and the environment of water conservancy and hydropower facilities. Testing work usually includes inspection and testing of water bodies, reservoirs, dams, canals, pumping stations, generator sets, and other aspects.

[0003] When conducting water conservancy and hydropower testing, it is necessary to use sample collection equipment to collect water samples from the water body in order to analyze various physical, chemical and biological indicators in the water body, thereby assessing water quality, ecological health and possible pollution sources.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When using existing ordinary sample collection equipment, it is usually necessary to manually put it into the water and then lift it up with the help of a cable, which is time-consuming and laborious; 2. When using existing ordinary sample collection equipment, it can usually only collect a single water mass at a time, and cannot perform stratified sampling according to needs, so its applicability is poor.
