Problems solved by technology

[0003] At present, the sampling of sediment is still carried out through the traditional sampling method, and the sampling method cannot be changed according to the softness and hardness of the bottom of the river. In addition, the existing sediment sampling device for river management cannot directly separate the sediment. , can not improve the efficiency for the follow-up work

Abstract

The invention discloses a sediment sampling device for river regulation. The device comprises a sampling cylinder, a first box body, a second box body and a third box body, openings are formed in thetwo ends of the sampling cylinder correspondingly, cylinder covers are connected to the two openings in an abutting mode correspondingly, the two cylinder covers are symmetrically arranged, and a first arc-shaped block and a second arc-shaped block are welded to the top of the sampling cylinder; the second arc-shaped block is located in the center of the top of the sampling barrel, the two first arc-shaped blocks are located at the two ends of the top of the sampling barrel correspondingly, a tensioning mechanism used for tensioning the two barrel covers is arranged on the side face of the sampling barrel, and grooves are formed in the tops of the two first arc-shaped blocks and the top of the second arc-shaped block correspondingly; the interior of the sampling cylinder is divided into afirst inner cavity and a second inner cavity, a filtering mechanism used for filtering silt is arranged in the second inner cavity, and the first box body is rotatably connected into a groove in the top of the second arc-shaped block. The practicability of the sampling device is improved.

Description

technical field [0001] The invention relates to the technical field of sediment sampling, in particular to a sediment sampling device for river channel regulation. Background technique [0002] River management is the engineering measures to control and transform the river. Scouring and silting often occur in natural rivers, which are prone to water damage and hinder the development of water conservancy. It is necessary to sample sediment during the process of river management. [0003] At present, the sampling of sediment is still carried out through the traditional sampling method, and the sampling method cannot be changed according to the hardness of the bottom of the river. In addition, the existing sediment sampling device for river management cannot directly separate the sediment. , can not improve the efficiency for the follow-up work. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose...
