Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] In order to eliminate or reduce the potential safety hazards in the existing technology, reduce labor costs and maintenance costs, and improve the accuracy of fire extinguishing, a lithium battery fire extinguishing method and fire extinguishing device based on a fire detector tube is proposed. Compared with the existing complex design, the fire extinguishing device of the present invention is simple, has higher fire extinguishing efficiency, and can prevent battery re-ignition for a long time.

[0034] The lithium battery fire extinguishing device based on the fire detection tube of the present invention includes a controller, a smoke sensor, a temperature sensor and a fire detection tube 6; the fire detection tube 6 has a pressure sensor, wherein the controller includes a host; the smoke sensor and the temperature sensor are set In the battery prefabricated ...

Abstract

The invention relates to a fire extinguishing device, a fire extinguishing method, a controller and a computer readable storage medium, a smoke sensor and a temperature sensor are arranged in an electrical area of a prefabricated cabin energy storage system of a battery, the smoke sensor and the temperature sensor are both connected with the controller, and collected smoke sensor and temperature sensor signals are sent to the controller; the fire trace tube is used for extending into a battery area of a prefabricated cabin energy storage system of a battery; the controller is used for judging whether an electrical area of the prefabricated cabin energy storage system of the battery is on fire or not according to the received smoke sensing and temperature sensing signals, and if yes, heptafluoropropane is adopted for extinguishing fire; and judging whether the battery area of the prefabricated cabin energy storage system of the battery is on fire according to the pressure of the fire trace tube, and if so, breaking the fire trace tube and extinguishing fire. According to the invention, the fire detection tube extends into the battery cabinet, so that the front-end detection is high in interference resistance and cannot receive external electromagnetic interference; the fire extinguishing device can effectively and quickly extinguish open fire of the battery through a fire extinguishing agent.

Description

technical field [0001] The invention belongs to the technical field of battery fire extinguishing, and in particular relates to a fire extinguishing device, a fire extinguishing method, a controller and a computer-readable storage medium. Background technique [0002] Lithium-ion batteries have the advantages of large specific capacity, high working voltage, long cycle life, small size, light weight, etc., and they have been used more and more as high-energy power sources. However, the heat generated by the lithium battery can easily cause safety hazards, especially when the battery is charged and discharged with a high current, it can easily cause the battery to explode, thereby causing harm to personal safety and the environment. In addition, the internal heat of a battery module composed of multiple batteries is higher, and after a single battery fails, if it explodes or burns in an abnormal situation, how to quickly extinguish the flame, reduce the impact on other batter...
