Description

Technical Field

[0001] This utility model relates to the field of rescue vehicle equipment technology, and in particular to a dual-combination transfer system for medium and heavy-duty hazardous chemical rescue vehicles. Background Technology

[0002] When transport vehicles carrying liquid hazardous chemicals (strong acids, strong alkalis, strong corrosives, and flammable and explosive substances) experience tank leaks or accidents during transport, it is necessary to urgently transfer the hazardous chemicals in the tanks to prevent large-scale leaks, fires, explosions, and other serious accidents, reduce environmental pollution, and quickly restore traffic.

[0003] In existing technologies, emergency rescue vehicles are generally used to transfer liquid hazardous chemicals. However, existing emergency rescue equipment is limited in function and has poor mobility. It is only equipped with a single system for transferring strong acid and strong alkali liquids, or a single system for transferring flammable and explosive liquids. Before the transfer, the transfer system needs to be evacuated, which requires an emergency rescue vehicle carrying the vacuuming system. This makes it very inconvenient to use and results in low emergency rescue efficiency. Utility Model Content
