A sediment sampling device

Abstract

The invention discloses a bottom mud sampling device. The placing platform is provided with an adjustment mechanism for adjusting the levelness of the placing platform, and the placing platform is provided with a through hole for communicating with a sampling pipe, and the end of the sampling pipe is snapped into the through hole. , a mud plug for pushing the mud column in the sampling tube is provided directly below the through hole, and the mud plug is connected with a driving mechanism; a sampling tube fixing frame is arranged on one side of the placement platform, and the sampling tube fixing frame is connected to the upper end of the sampling tube A knife switch is set at the level, and a sample cutter is set on the spring of the knife switch. The sampling tube holder directly above the sampling tube is provided with a rotatable sample dish turntable, and each sample dish can reach the front of the sampling tube. Above; the sample dish turntable is linked with the cutter switch. The horizontality of the placement platform is adjusted by the adjustment mechanism, and the sampling tube holder can keep the sampling tube in a fixed state during the sample dividing process; the mud plug is conducive to ensuring continuous and complete sampling of the sample under the premise of no disturbance, no deformation, and no pollution.

Description

technical field [0001] The invention relates to the technical field of water body depositional environment research, in particular to a sediment sampling device. Background technique [0002] The sediment of lakes and rivers is the main enrichment site and source of pollutant release in water bodies. The research on the properties of sediment and the characteristics of the occurrence and migration of pollutants can explain the pollution history and current situation of the water body environment. The results of the analysis and research of sediment are of great significance to the research and governance of the water environment. The collection and sub-sampling of sediment samples is the basis of research, which has a positive impact on improving research efficiency and the quality of research results. At present, the development of sediment samplers is diverse, but the research on sediment sampling devices is still relatively lagging behind. The existing sediment sampling ...

Problems solved by technology

At present, the development of sediment samplers is diverse, but the research on sediment sampling devices is still relatively lagging behind. The existing sediment sampling devices are often a supporting product of a certain sediment sampler, and the scope of use is limited and cannot be adapted to Requirements for actual sediment sampling

Moreover, when the sediment is manually cut, there will be some differences in the cutting of the mud column collected in different depositional environments, which will affect the accuracy and accuracy of the index analysis.

At the same time, various sediment samplers have the problems of easy sampling and difficult sampling. Field operations often require the cooperation of multiple people and work efficiency is low.
