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.

AI Technical Summary
In existing technologies, cleaning agencies rely on manual pushing of the push rod, which leads to high labor intensity for operators, and the collection tube is difficult to accurately position when sampling water layers, which can easily cause leakage.
The sampling depth is controlled by a threaded assembly and a motor-driven lifting plate. The filter screen is cleaned automatically. The collection cylinder is accurately positioned using an elastic component. The filter screen is detachable and the positioning ball is engaged to achieve accurate positioning of the collection cylinder through bolt connection.
It improves the ease of use and maintainability of the sampling device, reduces manual labor intensity, ensures the accuracy of sampling depth and the stability of collection, avoids leakage, and improves work efficiency.
