The invention relates to a soft cloth subsealing type shallow water undisturbed surface
sediment sampler comprising a sampling sleeve, a sampling mechanism and a sampling liner. The soft cloth subsealing type shallow water undisturbed surface
sediment sampler is characterized in that the sampling sleeve comprises a sampling
drill bit, a sampling cylinder, an outer counterweight
deckle board, an upper cover plate and a hard connecting rod; the sampling mechanism comprises a lifting
rope, a lifting rod, a lifting rod fixing frame, a side face connecting shaft, a side face connecting shaft baffle, a cable wire, a
pulley, a slide rail of side face connecting shaft, a bottom connecting shaft, soft waterproof subsealing cloth, a spring bolt and a fixing mechanism of soft waterproof subsealing cloth; and the sampling liner comprises a sampling liner outline border, a sampling liner soleplate and a sampling liner soleplate inserting mechanism. The soft cloth subsealing type shallow water undisturbed surface
sediment sampler disclosed by the invention has the advantages of large sampling area, high sampling success rate, non-damage on
physical structure and
sequence structure of surface sediment, and the like, and the sampler is capable of meeting collecting demand of shallow water surface sediments and is particularly suitable for collecting surface sediment samples within 3m
water depth.
