If the fire is judged by adopting the visual identification technology, the cost is higher. If the temperature sensing is adopted to judge whether the equipment is on fire or not, misjudgment is possibly generated, and when the temperature in the equipment is too high due to the external environment or the heat dissipation problem, all the fire extinguishing agents are released at one time, so that the serious waste of the fire extinguishing agents is caused.

As shown in fig. 1 to 3, the present embodiment provides a temperature-sensing self-starting fire extinguishing apparatus, including a fire extinguishing pipe 1, where the fire extinguishing pipe 1 has a double-layer structure, and includes an inner-layer pipe 2 and an outer-layer pipe 3, and fire extinguishing agents 4 are filled in the inner-layer pipe 2 and between the inner-layer pipe 2 and the outer-layer pipe 3; the bottom of the fire extinguishing pipe 1 is provided with a plug 5, and the top is provided with a sealing membrane 6; a self-starting device is arranged on one side, away from the fire extinguishing pipe 1, of the sealing diaphragm 6, the self-starting device comprises a cylinder body 7 with an opening at the bottom, a control module 8 and a puncture mechanism are arranged inside the cylinder body 7, a plurality of release holes 9 are formed in the side wall of the cylinder body 7, a temperature sensor 10 is arranged outside the cylinder body 7, and the temperature sensor 10 and the puncture mechanism are respectively and electrically connected with the control module 8;
when the temperature sensor 10 detects that the temperature of the air outside the cylinder 7 exceeds a set threshold value T1, the control module 8 controls the puncture mechanism to puncture the sealing diaphragm 6 on the outer ring of the top of the fire extinguishing pipe 1, and at the moment, the fire extinguishing agent 4 between the inner layer pipe 2 and the outer layer pipe 3 is diffused to the outside of the cylinder 7 through the release hole 9 on the side wall of the cylinder 7 to perform primary fire extinguishing and temperature reduction on the environment outside the cylinder 7; after the delay time T, if the temperature sensor 10 detects that the temperature of the air outside the cylinder 7 still exceeds the set threshold T1, the control module 8 controls the puncturing mechanism to puncture the sealing membrane 6 at the inner ring at the top of the fire extinguishing pipe 1, and at this time, the fire extinguishing agent 4 inside the inner pipe 2 is diffused to the outside of the cylinder 7 through the release hole 9 on the side wall of the cylinder 7 to perform secondary fire extinguishing and temperature reduction on the environment outside the cylinder 7.
In the embodiment, the fire extinguishing pipe 1 is of a double-layer structure, so that the fire extinguishing agent 4 can be released in stages, and waste caused by releasing the fire extinguishing agent 4 at one time due to small fire or overhigh internal temperature of the equipment is avoided; meanwhile, the installation space of the fire extinguishing device can be saved, so that the fire extinguishing device can be installed in small and miniature electrical equipment; the fire extinguishing agent 4 between the outer layer pipe 3 and the inner layer pipe 2 can be fully released into the electrical equipment by setting the delay time, and the misjudgment of the temperature sensor 10 caused by the insufficient release of the fire extinguishing agent 4 is avoided.
Preferably, the puncture mechanism comprises a telescopic motor 11, a telescopic rod 12, a mounting plate 13 and a puncture column, wherein the telescopic motor 11 is electrically connected with the control module 8; the telescopic motor 11 is arranged at the top of the barrel 7, one end of the telescopic rod 12 is connected with the output end of the telescopic motor 11, and the other end of the telescopic rod is connected with the mounting plate 13; the barbed columns comprise a first barbed column 14 and 4 second barbed columns 15, and the first barbed column 14 is arranged in the right center of the mounting plate 13; 4 second spikes 15 are circumferentially arranged along the first spike 14; the first barbed columns 14 are positioned above the inner-layer pipe 2; the 4 second barbed posts 15 are positioned above the interval between the inner layer tube 2 and the outer layer tube 3; the second spike 15 is longer than the first spike 14.
