The invention relates to a cable pit fire extinguishing device which comprises a bottle body, a powder outlet pipe and a blowing device, wherein the powder outlet pipe comprises at least one hard pipe, and the hard pipe is made of UPVC; one end of the hard pipe communicates with the bottle body, and the other end of the hard pipe is connected with the blowing device; and the blowing device comprises a diffusion unit, and the diffusion unit communicates with the hard pipe and is used for diffusing a fire extinguishing agent input from the hard pipe. One end of the hard pipe communicates with the bottle body, and the other end of the hard pipe is connected with the blowing device, so that the fire extinguishing agent in the bottle body smoothly reaches the blowing device through the hard pipe; the hard pipe is made of UPVC and has the functions of fire prevention, flame retardance and better insulating property, so that when a cable pit is on fire, the hard pipe can quickly reach a specified position; and the diffusion unit of the blowing device communicates with the hard pipe, and the fire extinguishing agent input from the hard pipe is uniformly distributed on the whole fire breakout pit through the diffusion unit, so that the problem that the fire extinguishing efficiency is low due to the fact that the fire extinguishing agent is difficult to accurately convey to a fire source because the deep condition of the pit is unknown is solved.

    本发明涉及一种电缆坑灭火装置,包括瓶体、出粉管、吹风装置,其中:出粉管包括至少一个硬质管,硬质管的材料为UPVC;硬质管的一端与瓶体相连通,硬质管的另一端与吹风装置相连;吹风装置包括扩散单元,扩散单元与硬质管相连通,用于扩散从硬质管输入的灭火剂。通过将硬质管的一端与瓶体相连通,硬质管的另一端与吹风装置相连,顺利的让瓶体内的灭火剂通过硬质管到达吹风装置;硬质管的材料为UPVC,具有防火阻燃且绝缘性能较好的功能,当电缆坑起火时,能快速到达指定的位置;吹风装置的扩散单元与硬质管相连通,从硬质管输入的灭火剂通过扩散单元均匀地布满整个起火坑道,解决了坑道深处情况未知,难以将灭火剂精准输送到火源使灭火效率低下的情况。
