Novel stable sampling device for water pollution control

The utility model provides a novel stable sampling device for water pollution control, which comprises a protective shell, an air cavity, a guide frame, a protective outer frame structure, a driving winding frame structure, a double-layer sampling frame structure, a top shield, a mounting frame, a storage battery, a control chip, a wireless module, an adjustable protective side frame structure, a collecting frame, a winding shaft, a rotating handle and a protective rope, the air cavity is embedded in the periphery of the interior of the protective shell. The guide frame is embedded in the middle position of the protective shell; the protective outer frame structure is installed on the upper middle portion of the protective shell. The driving winding frame structure is installed on the upper portion of the protective outer frame structure. The hoisting rope is wound on the outer side of the take-up roller, so that the height of the whole double-layer sampling frame structure in water can be conveniently and fl
