AI Technical Summary

Technical Problem

Existing sediment sampling devices often result in incomplete sampling because samples from different layers tend to mix during the sampling process.

Method used

A sampling bucket comprising a flexible encapsulation sheet and a sandwich structure was designed. The movement of the encapsulation sheet is controlled by a drive component to ensure that the sample is not squeezed and mixed after sampling, and moisture is discharged by a pressure plate. Combined with a secondary sealing component, the integrity of the sample is further guaranteed.

Benefits of technology

This effectively prevents the mixing of sediment samples during the sampling process, ensuring the integrity and stability of the samples and improving the accuracy of the sampling results.

Abstract

This invention discloses a sediment sampling device, relating to the technical field of sediment sampling. The device includes a sampling bucket with an open bottom and a flexible encapsulation sheet. The lower section of the sampling bucket has a sandwich layer that can accommodate the vertical movement of the encapsulation sheet. The inner wall of the sampling bucket has a second through-hole and a first sliding groove. The second through-hole communicates with the lower part of the sandwich layer, and the first sliding groove communicates with the sandwich layer end to end through the second through-hole. One end of the encapsulation sheet is slidably connected to the first sliding groove via a connecting rod, and the other end extends into the sandwich layer and is connected to a driving component. When the connecting rod slides to a set position in the first sliding groove, the encapsulation sheet seals the bottom of the sampling bucket. After sampling, the encapsulation sheet stores the sediment in the sampling bucket. This sampling method does not penetrate or compress the sediment sample, thus ensuring the integrity of the sediment sample.
