Sludge multi-position sampling device for pond

Abstract

The invention belongs to the technical field of sludge sampling, and particularly relates to a pond sludge multi-position sampling device which comprises a sampling frame. A plurality of storage cavities are vertically and uniformly formed in the sampling frame; the top end of the sampling frame is fixedly connected with an electric push rod; the output end of the electric push rod is fixedly connected with a sliding plate, and the sliding plate is slidably connected to the inner wall of the sampling frame. The efficient pond sludge multi-position sampling device is achieved by combining the electric push rod, the sliding plate, the n-shaped plates and the multi-stage blocking structure, the sampling frame is inserted into sludge mainly through the power telescopic assembly, and the sludge at different position depths is collected into the n-shaped plates at the same time; the sludge is pushed into the storage cavities by the sliding plate for temporary storage and sampling, meanwhile, the adjustable partition plates are adopted, the required sampling amount can be selected according to different areas and depths, the positions of all the partition plates are synchronously adjusted through linkage of the limiting frame and the rack plate, or the positions of the partition plates are respectively adjusted, and the sampling effect can be improved.
