[0002] A reservoir refers to an artificial lake that stores water resources. It is usually located above a river channel. Water is accumulated into an artificial lake by introducing river water from all directions. The characteristics of a reservoir are that the water flow is relatively static, but there is still a certain degree of fluidity. In addition, the water level of the reservoir varies greatly. Since the water quality of the water introduced into the reservoir varies greatly and the water in the reservoir also has a certain degree of fluidity, it is necessary to conduct continuous water quality monitoring of the water quality in the reservoir. The basis of water quality monitoring is the acquisition of water samples. The existing sampling mainly has the following problems.
