[0002] During the application of the energy storage cabinet, the safety of use plays a crucial role, especially the fire-fighting module. In the process of using the energy storage module inside the energy storage cabinet, spontaneous combustion is likely to occur. Therefore, a fire-fighting module is usually installed inside the energy storage cabinet to deal with special situations. However, currently, the fire-fighting module usually installs a temperature-sensitive conduit inside the battery module, and uses a fire-fighting gas cylinder to fill fire-fighting gas into the temperature-sensitive guide rail. During use, if the temperature inside the battery module is too high, the temperature-sensitive guide rail will rupture and the fire-fighting medium will be released. But currently, the fire-fighting measures are relatively single, and further dangers are likely to occur when the fire and temperature cannot be effectively controlled. Content of the Utility Model
