Description

Technical Field

[0001] The invention belongs to the technical field of environmental vehicles, and in particular relates to a vehicle-mounted laboratory and a soil detection vehicle with ventilation and purification functions. Background Art

[0002] With the continuous improvement of the industrialization process and the relocation of urban and rural areas, a large number of polluted sites have been left behind. A large amount of soil organic pollution needs to be investigated and repaired. The top priority is to collect samples, test and analyze the polluted sites. At present, most soil investigation and remediation industries use drilling rigs to drill soil samples, and then require test personnel to arrive at the test site to collect and pack samples, and then send them to fixed laboratories for experimental analysis. There is no guarantee that the samples will not be contaminated again, and the authenticity and reliability of the analysis data cannot be guaranteed. In addition, the laboratory experiment cycle is long and the detection efficiency is low.

[0003] The soil testing vehicle is a mobile vehicle used for soil investigation and remediation. It integrates a pure electric chassis, an on-board laboratory, an equipment compartment, etc., to achieve the purpose of quickly testing soil samples and conducting experimental analysis. Most mobile laboratories on the market are modified from small vans. Limited by the space of the original vehicle, the instruments and equipment that can be placed are very limited (only soil nutrient meters are carried), the detection function is single, and the working space is narrow and the operator's comfort is poor. At present, the more advanced on-board laboratories of soil testing vehicles are equipped with workbenches, tool boxes, testing equipment, lighting, etc., which can detect organic toxins in soil samples, but cannot handle toxic gases during sample processing. There are risks such as secondary contamination of samples, pollution of ambient air, and harm to operators by toxic gases. In addition, the existing on-board laboratories have unreasonable layouts and low space utilization. Summary of the invention
