AI Technical Summary

Technical Problem

Existing methods for extinguishing electric vehicle battery fires, such as traditional sprinkler systems and fire hoses, are inefficient and pose risks to firefighters due to the inability to directly target the battery and the hazardous nature of jet-like directional flames and combustible gases.

Method used

A fixed fire detection and prevention system with upwardly spraying nozzles and a control system that activates water flow to the nozzles upon detecting a fire risk, using a permanent water supply and sensing elements to direct water towards the vehicle's underside.

Benefits of technology

Effectively cools the battery and contains the fire, reducing the risk to firefighters and adjacent vehicles by directly targeting the fire source and minimizing the spread of flames and gases.

Abstract

A system for fire detection and prevention including a frame, an inlet connected to the frame and connectable to a water supply and a plurality of spray nozzles located on the frame. Each of the spray nozzles is in fluid communication with the inlet and configured to spray water received from the water supply outwards in a substantially upwardly direction and one or more of the plurality of the spray nozzles includes a deflector plate secured thereto, to at least partially obstruct water flow and direct the water being sprayed from respective spray nozzles into a pre-determined direction. The system also includes at least one sensing element located on the frame configured to detect a fire risk associated with one or more components of a stationary vehicle located over the frame. The sensing element is controlled by a control system configured to allow water to flow from the water supply to the plurality of spray nozzles in response to the at least one sensing element detecting a fire risk.
