Water body layered sampling device for environmental monitoring

The sampling depth is controlled by a threaded assembly and a motor-driven lifting plate. The filter screen is cleaned automatically, and the elastic component enables accurate positioning of the collection cylinder. This solves the problems of high labor intensity and inaccurate positioning of the collection cylinder caused by manual pushing of the cleaning mechanism in the existing technology, and achieves efficient and stable water stratification sampling.
