Sampling device for contaminated soil regeneration

Abstract

The invention provides a sampling device for contaminated soil regeneration, which comprises a main body, a mounting part is fixedly mounted on the lower side of the main body, a movable baffle is movably mounted on the lower side of the mounting part, a driving mechanism is arranged on the lower side of the mounting part, and a rotating shaft is movably mounted on the front side of the driving mechanism; and the front end of the rotating shaft is fixedly connected with a driving gear. According to the sampling device for contaminated soil regeneration, when the main body enters the soil and continuously moves downwards, the pressure of the soil is pressed to the water pressure detection mechanism, the pressure borne by the water pressure detection mechanism becomes larger and larger alongwith continuous downward movement of the main body, water in the water pressure detection mechanism is pressed upwards, and meanwhile the water makes contact with the movable part; the sensing blockis in contact with the sensing part through buoyancy of the movable part, a user is reminded that the set distance under the ground is reached, and therefore the effect that the equipment knows the soil sampling depth through soil pressure is achieved.

Description

technical field [0001] The invention belongs to the technical field of polluted soil regeneration, and in particular relates to a sampling device for polluted soil regeneration. Background technique [0002] Contaminated soil remediation refers to the use of physical, chemical, biological and ecological principles, and the use of artificial control measures to reduce the concentration (activity) of soil pollutants, realize the harmlessness and stabilization of pollutants, and achieve the desired detoxification effect. Theoretically feasible remediation technologies include phytoremediation, microbial remediation, chemical remediation, physical remediation, and comprehensive remediation. Some remediation technologies have entered the field application stage and achieved good results. Remediation of contaminated soil It is of great significance to block pollutants from entering the food chain, prevent harm to human health, and promote land resource protection and sustainable d...

Problems solved by technology

[0003] Nowadays, pollutants are often stored in various forms in the soil, and different chemical forms have different effectiveness. Therefore, soil regeneration is required artificially. Before soil regeneration, the contaminated soil will be sampled and tested to determine the cause of soil pollution. To deal with the pollution situation in a targeted manner, the existing soil sampling equipment can only collect the soil on the soil surface, but cannot collect the soil under the ground, so that the pollution of the soil cannot be effectively detected, and it is difficult to achieve people's expected results , and the traditional equipment is complex in structure and has high limitations in use
