Environment detection sampling device suitable for wetland soil

Abstract

The invention discloses an environment detection sampling device suitable for wetland soil, which belongs to the technical field of environment detection, and can specially measure the wetland soil with strong flowability. At the beginning, a communication hole and a sample introduction hole are staggered, so that the soil above cannot flow into a sampling area in the process of inserting a square sampling barrel into the wetland soil, elastic triggering balloons are arranged in a distinguishing manner, so that when the sampling areas are deepened to the matched depth, the corresponding communicating holes and the sampling holes can be automatically overlapped and communicated, soil enters the sampling areas to be sampled, and a plurality of sampling areas can be used for correspondingly collecting soil samples with different depths, so that the working efficiency can be greatly improved. When the soil flows into the sampling areas, the communicating hole is staggered from the sample introduction hole again, so that the soil above is effectively prevented from entering the sampling area when the square sampling barrel is taken back upwards, the sampling precision can be remarkably improved, and the accuracy of a detection result can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to an environmental detection and sampling device suitable for wetland soil. Background technique [0002] Soil environmental testing refers to an important measure to understand the quality of soil environment. For the purpose of preventing and controlling the hazards of soil pollution, the dynamic analysis and determination of the degree and development trend of soil pollution. Including the investigation of the status quo of soil environmental quality, the investigation of the background value of regional soil environment, the investigation of soil pollution accidents and the dynamic observation of polluted soil. Soil environment testing generally includes steps such as preparation, layout, sampling, sample preparation, analysis and testing, and evaluation. [0003] In a broad sense, wetland soil can be defined as a granular medium with a certain degree of soil ...

AI Technical Summary

Problems solved by technology

[0004] When testing the environment of wetland soil, it is necessary to sample the wetland soil, and in order to ensure the accuracy of the test, multi-depth sampling is usually required, that is, it is necessary to test the wetland soil at different depths, but due to the fluidity of the wetland soil Relatively large, the sampling device in the prior art, when sampling wetland soil, multi-depth sampling requires multiple sampling, which is troublesome to operate and low in efficiency, and during the sampling process, the soil above is easy to flow into the sampling cylinder. Lead to inaccurate sampling, which will affect the accuracy of test results
