Description

Water quality monitoring device Technical Field The invention relates to the technical field of water quality monitoring, in particular to a water quality monitoring device. Background Still water is subject to stable thermal stratification, typically three layers, due to solar radiation heating and density differences, while in deep water bodies, such as sea areas, there are more than three layers, more than ten layers of which are monitored for scientific grade profile of the body, for example in bodies where parameters such as Dissolved Oxygen (DO), hydrogen sulfide (H2S), pH, chlorophyll etc. often undergo orders of magnitude mutation within thin layers of a few centimeters to tens of centimeters. In view of the foregoing, the layering capability of the monitoring device has a certain correlation to the monitored data result, and in the prior art: The embedded fixed-point monitoring depth is single, water conditions such as a jump layer, a thin layer algal bloom and the like are difficult to analyze, and the more point positions are needed to be erected for realizing multi-depth monitoring; Although the input type mobile monitoring has flexibility, each movement can form disturbance to the water body, the monitoring result is influenced to a certain extent, and meanwhile, the input depth reference is difficult to obtain.
