The hot-melting overflowing air bag 9 comprises a conical heat conducting bag embedded on the heat dissipation source extinguishing box 2, an overflowing hole communicated with the air storage cavity and the heat insulation cover 8 is formed in the conical heat conducting bag, a hot-melting sealing ball is arranged in the overflowing hole in a plugging mode and made of hot-melting materials, the source extinguishing gas is a mixture of carbon dioxide and inert gas in a mass ratio of 2:1, when the heat insulation blocking pipe 10 is conducted highly, the temperature of the heat insulation cover 8 rises, the heat conduction sealing ball in the hot-melting overflowing air bag 9 is pyrolyzed to expose the overflowing hole, the source extinguishing gas overflows, is guided to the hollow heat conducting rod 503 through the hot-melting overflowing air bag 9, the heat insulation cover 8, the heat insulation blocking pipe 10 and the heat conduction cover 7 and is guided to the interior of the lightning protection device body 1 through the hollow heat conducting rod 503, and is used for inert source extinguishing in a high-temperature environment and fire conditions generated in the lightning protection device body 1.

According to the invention, the heat conductors 5 for heat conduction are arranged on two sides of the lower end of the lightning protector body 1, the heat conductors 5 conduct heat inside the lightning protector body 1 to the heat dissipation cavity of the heat dissipation failure source box 2 and diffuse outwards through the pair of heat dissipation bodies 4 to achieve sufficient heat dissipation, when the temperature in the lightning protector body 1 gradually rises to reach the dangerous range of fire, the high temperature enables the heat conduction deformation body to deform, expand and prop on the heat insulation blocking body so as to remove the blocking environment of the heat insulation blocking body, at the moment, the high temperature environment is transmitted to the heat insulation cover 8 through the heat insulation blocking body, so that the hot melting gas overflowing effect is achieved on the hot melting gas overflowing air bag 9, the extinguishing gas in the gas storage cavity is guided into the lightning protector body 1 through the heat insulation blocking body, the heat conduction cover 7 and the heat conductors 5, and the fire source is extinguished, so that the fire condition caused by the high temperature is effectively prevented.

The components used in the present invention are all standard components or components known to those skilled in the art, and the structure and principle thereof can be known to those skilled in the art through technical manuals or through routine experiments.

The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
