Abstract
The present disclosure relates to a fire extinguishing device and system for suppression of electric vehicle battery fire and, more specifically, to a fire extinguishing device and system wherein in the event of a fire caused by a battery of an electric vehicle, the fire extinguishing device is moved to a space under the electric vehicle, a nozzle tip rod protrudes upward such that a part of the nozzle tip rod is inserted into the battery pack mounted on the bottom of the vehicle, and then firefighting water or a fire extinguishing agent is injected and charged into a space inside the battery pack, thereby quickly stabilizing the battery and preventing additional fires caused by battery explosion.
Claims6
A fire extinguishing device for suppression of an electric vehicle battery fire, the fire extinguishing device comprising:
- a mobile vehicle body equipped with a movable wheel to move to a space under an electric vehicle, and having a plurality of outlet holes formed through an upper surface thereof and a connection terminal formed on a side surface thereof;
- nozzle tip rods vertically installed under each of the plurality of outlet holes of the mobile vehicle body, having a pointed upper end to penetrate a battery pack placed on a bottom of the electric vehicle when rising vertically, so as to be partially inserted into the battery pack, and having a plurality of nozzles formed on a side surface inserted into the battery pack, to inject firefighting water or a fire extinguishing agent supplied through the connection terminal;
- hydraulic or pneumatic cylinders installed inside the mobile vehicle body to vertically move the nozzle tip rods by receiving hydraulic or pneumatic pressure through the connection terminal;
- and
- a control panel connected to the mobile vehicle body by a wire to control operation of the hydraulic or pneumatic cylinders,
- wherein a hydraulic or pneumatic lift is further installed on the mobile vehicle body such that a support protrudes downward to raise the mobile vehicle body when hydraulic or pneumatic pressure is supplied thereto, thereby enabling operation of the nozzle tip rods when the mobile vehicle body is in direct contact with the bottom of the electric vehicle.
