The invention relates to the technical field of elevator safety early-warning devices, in particular to an elevator fire-fighting early-warning device which comprises a smoke sensing alarm and further comprises a draft fan detachably installed at the top end of an elevator car through an installation plate, and a smoke exhaust pipe is installed on the draft fan; the protection unit comprises a gathering bin installed at the smoke outlet end of the smoke extraction pipe and a flame extinguishing bin installed in the gathering bin, and the flame extinguishing bin is filled with fire extinguishing filler used for extinguishing sparks; a vertical bin is connected to the position, corresponding to the flame extinguishing bin, of the gathering bin in a communicating mode, and a dust filtering cylinder is installed in the vertical bin. According to the fire-fighting early warning device for the elevator, smoke in the elevator car can be sucked away through the smoke suction pipe and the suction fan, so that the smoke obtains guidance quality; the flame extinguishing bin is matched with the fire extinguishing filler, so that sparks in smoke can be extinguished, and fire spreading is slowed down; solid particles in the flue gas are further filtered by the dust filtering cylinder, so that the harm in the flue gas diffusion process is reduced, and more buffer time is won for crowd evacuation and fire rescue.
本发明涉及电梯安全预警装置技术领域,具体涉及一种电梯消防预警装置,包括烟雾传感报警器,还包括:抽风扇,通过安装板可拆卸安装在电梯轿厢顶端,抽风扇上安装有抽烟管;防护单元,包括安装在抽烟管出烟端的汇聚仓,以及安装在汇聚仓内的熄焰仓,熄焰仓内部填充有用于扑灭火星的灭火填料;汇聚仓上且位于熄焰仓对应处导通连接有竖仓,竖仓内部安装有滤尘筒;该电梯消防预警装置,通过抽烟管以及抽风扇,能够抽离电梯轿厢内部的烟气,使得烟气获得导向性;通过熄焰仓配合灭火填料能够扑灭烟气中的火星,减缓火灾的蔓延;滤尘筒进一步过滤烟气中的固体颗粒,降低烟气扩散过程中的伤害性,为人群撤离和消防救援争取更多的缓冲时间。
