DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment one

[0026] Please refer to Figures 1 to 8 The utility model provides a kind of technical solutions: a kind of fire extinguishing device convenient to assemble, including cable trench 1, cable trench 1 is equipped with cover plate 2, cover plate 2 is opened with round groove 20, cable trench 1 inside two sides are fixedly installed with cable support 3, cable support 3 is fixedly connected with the inner wall of cable trench 1, cable support 3 is equipped with three support legs 30, for placing and fixed cable, cable trench 1 is also equipped with dismounting device 4, dismounting device 4 is also equipped with fire extinguishing device 5.

[0027] Dismounting device 4 includes tray 40, tray 40 is fixedly installed in the bottom of cable trench 1, support frame 41 is rotatably installed in tray 40, support frame 41 outside is equipped with screw thread, support frame 41 two sides are equipped with clamping block 411, coil spring 42 is connected between support frame 41 and tray 40, shell 43 is screw thread installed on support frame 41, shell 43 lower inner side is equipped with screw thread, the size of the upper circular of shell 43 is equal to the size of round groove 20, round hole 430 is opened in the upper part of shell 43, the size of round hole 430 is equal to alarm lamp 410, fire extinguishing device 5 includes perfluorohexone bottle 44, perfluorohexone bottle 44 is equipped on support frame 41, signal processor 45 is equipped on perfluorohexone bottle 44, injection nozzle 46 is loaded on signal processor 45, smoke sensor 47 is installed on the upper part of signal processor 45, pressing plate 48 is equipped above smoke sensor 47, pressing plate 48 can freely slide in shell 43, clamping rod 480 is equipped on the two sides of pressing plate 48, clamping rod 480 can be clamped in the side of clamping block 411, spring 49 is equipped between pressing plate 48 and smoke sensor 47, alarm lamp 410 is fixedly installed on the upper side of pressing plate 48.

[0028] When the cable in the cable trench 1 catches fire, the smoke sensor 47 can sense the smoke generated by the burning of the cable protection layer and transmit a signal to the signal processor 45, and the signal processor 45 sprays the perfluorohexone nozzle 46 in the perfluorohexone bottle 44 immediately after receiving the signal, extinguishes the flame, and prevents the fire from spreading.
