AI Technical Summary

Technical Problem

Existing methods for extinguishing electric vehicle fires, particularly those involving high-capacity batteries, are inefficient and risky, as they often require large water tanks and cranes, and traditional extinguishing methods struggle with re-ignition due to the battery's high heat and density.

Method used

A motor-driven drill lance device that automatically drills a fire extinguishing hole in the electric vehicle battery using a motor-powered drill module and injects water to extinguish the fire.

Benefits of technology

The device quickly and effectively prevents thermal runaway and re-ignition by directly cooling the battery, reducing wear on the drill mechanism, and can operate with low water pressure, making it suitable for indoor hydrants and existing water supply systems.

Abstract

To provide a motor-type drill lance device for extinguishing vehicle fires, which automatically drills a fire extinguishing hole in the lower part of an electric vehicle battery using the power of a motor when a fire breaks out in the battery, and then sprays water to quickly extinguish the fire. [Solution] The motor-type drill lance device for vehicle fire extinguishing of the present invention includes a height-adjustable trolley (110) that moves and positions under the electric vehicle battery, and a drill module (120) that is installed under the upper plate of the height-adjustable trolley (110) and is in close contact with the electric vehicle battery. The drill module drills holes in the electric vehicle battery using the power of the motor while in close contact with the electric vehicle battery, and then sprays water into the electric vehicle battery through the drilled holes to extinguish a fire that has broken out in the electric vehicle battery.
