Sampling device for polluted soil

Abstract

The invention relates to a sampling device for polluted soil, and belongs to the technical field of environmental equipment. The sampling device comprises a positioning structure, a sampling structureand an elastic blocking structure, wherein the positioning structure comprises a positioning cylinder with a cylindrical structure; a positioning internal thread is arranged on the inner side of thepositioning cylinder; a plurality of connecting angle lugs are arranged on the outer side of the positioning cylinder; supporting rods are arranged on the connecting angle lugs; supporting threaded holes are formed in the supporting rods; and lengthened screws are arranged in the supporting threaded holes. The sampling device has the beneficial effects that the device is positioned through the positioning structure, then soil sampling is realized through the sampling structure, and storage holes are blocked through the elastic blocking structure, so that the purpose of soil sampling is achieved. The sampling device is novel in structure and convenient to operate.

Description

technical field [0001] The invention relates to a sampling device for polluted soil, which belongs to the technical field of environmental equipment. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out contaminated soil treatment and restoration plans, so a new soil restoration industry has also formed, with "high pollution exceeding the standard rate" and "trillion-level market" "Complex system engineering" and "emerging industries in the early stages of development", China's soil pollution prevention and control is now entering the United Nations' first "I...

Problems solved by technology

[0003] Before the large-scale remediation of contaminated soil, sampling must be carried out, and the method of soil remediation can be obtained through the analysis of the samples. The existing sampling methods are various, and some of them use shovels to dig the soil. This method is time-consuming and labor-intensive. Large; some use large machines to take soil, although this method is more efficient, but the cost is higher, in view of the above problems, the industry needs a sampling equipment with a new structure, which can reduce costs while improving efficiency
