[0002] At present, in order to achieve comprehensive detection and accurate evaluation of the water environment, the environmental monitoring department, on the one hand, sets up multiple monitoring points in the water environment and uses water quality sensors to roughly understand the water environment pollution situation. On the other hand, it needs to use sampling devices to take samples in the water environment and send them to the laboratory for analysis, so as to clarify the composition of pollutants, improve the evaluation content, and formulate targeted water treatment plans.

[0003] When sampling water quality, it is necessary to use a small boat to reach the sampling point, and then use the sampling device placed on the small boat to sample. The sampling device in the prior art cannot perform water quality sampling operations at different depths very well, and generally uses a metal bucket / plastic bucket with a hanging rope, and throws the bucket into the sampling water body and then lifts it up to perform sampling. When the small boat floats on the water surface, the operator performs some large-scale operations (lifting the bucket upwards), which will affect the stability of the small boat and cause the sample water in the bucket to spill, directly affecting the stability of the sampling operation. Therefore, the utility model proposes a water quality sampling device for environmental evaluation to solve the shortcomings of the prior art. Utility Model Content
