Polluted site high-fidelity sampling device and method

Abstract

The invention discloses a high-fidelity sampling device and method for a polluted site, and the device comprises a vehicle body module, the vehicle body module is provided with a power module, the power module comprises a driving seat, a rotating shaft, a lifting sliding block, a main control assembly, a fixed frame, a winch, a mast, a first hydraulic rod, a second hydraulic rod, and a lifting guide rail; a first hydraulic rod and a second hydraulic rod are obliquely arranged on the vehicle body module, the lower end of the first hydraulic rod and the lower end of the second hydraulic rod are connected with a support of the vehicle body module through a first supporting hydraulic cylinder and a second supporting hydraulic cylinder, the upper end of the first hydraulic rod and the upper end of the second hydraulic rod are fixedly connected with a fixing frame, and a winch and a mast are arranged on the top of the fixing frame. The high-fidelity sampling technology for the contaminated site aims to solve the technical problems that in an existing soil sample collection technology, a device is insufficient in sealing performance, single and asymmetric in structure and insufficient in sample fidelity when sampling is conducted in a complex soil layer and a deep soil layer.
