Sampling device for water bodies with different depths

Abstract

The utility model discloses a sampling device for water bodies at different depths, which belongs to the technical field of water body sampling and comprises a frame and a plurality of sampling mechanisms, each sampling mechanism comprises a fixing component and a sampling component, the fixing component comprises a fixing cover, the fixing cover is of a cavity structure with an opening at the bottom, and the sampling component is arranged in the cavity structure. A plurality of water permeable holes for exhausting are formed in the top wall of the side wall of the fixed cover, two square grooves symmetrical about the axis of the fixed cover are formed in the side wall of the fixed cover, the sampling assembly comprises a folding water bag, the folding water bag is arranged on the inner top wall of a cavity of the fixed cover, and a water inlet pipe is arranged at the bottom end of the folding water bag. A matching plate is arranged at the bottom of the folding water bag, and arc-shaped clamping blocks located in the square grooves are arranged at the two ends of the matching plate. When the different-depth water body sampling device is used for sampling water bodies, bubbles cannot be discharged in the sampling process, and the probability that the water bodies with different vertical depths are mixed together due to the bubbles during vertical sampling is reduced.
