AI Technical Summary

Technical Problem

Existing fire extinguishing devices lack automatic adjustment capabilities when dealing with vehicle chassis fires. The sprayed water is prone to spillage and waste. They also lack the ability to cope with burning debris and complex environments. Furthermore, their electrical safety protection is inadequate, posing a risk of electric leakage.

Method used

A mobile circulating water curtain fire extinguishing vehicle was designed, which includes a water storage tank, an upward spraying unit, a water collection tray, a circulating filtration module, and an adaptive adjustment module to realize the recycling and automatic adjustment of the extinguishing agent. It adopts a closed insulating circuit and a tracked structure, and has electrical insulation and self-adaptive capabilities.

Benefits of technology

It achieves water conservation, improves fire extinguishing efficiency and adaptability, reduces water waste, ensures operational safety, and enables rapid and effective fire extinguishing in complex environments.
