高层灭火神器亮相国际消防展

2017-09-08 04:12:11   中国青年网

本报记者 马婧

在北京举行的第十七届国际消防展上,30多个国家和地区的参展商带来了世界最先进的消防设备,尤其是来自中国的企业,亮出了破解城市消防安全难题的“神器”。

长臂消防车“指哪儿打哪儿”

登高车、云梯车、高喷车……来到国家展览馆新馆,各类消防车映入眼帘,一排排伸直的“长臂”直指苍穹。

徐工集团展出一款举高消防车,它的工作高度已经从两年前的68米提高到100米,填补了国内68米以上超大型高举消防车的空白。

在跨度上,国产消防车也有了新突破。在三一重工展区,拥有6个关节的“长臂”大家伙格外抢眼。和直臂消防车不同,它的臂架可以自由折叠弯曲。据悉,这是三一重工和北京合作研发的大跨度举高喷射消防车,它的“长臂”可以跨越围墙、树木、平房等各种障碍物,臂架可灵活移动,让末端出水口最大限度接近火源,实现“指哪儿打哪儿”。

三一重工消防装备项目总监陈添明介绍,有了大跨度举高喷射消防车后,救援力量可轻松跨越障碍,直抵火场核心部位。针对狭窄街巷中火灾救援情况,大跨度高喷消防车可以伸出四条腿支撑在任意位置,支撑占地宽度最小只需3.3米,方便快速展开臂架进行消防救援。

据悉,48米大跨度举高喷射消防车已在北京试用,62米大跨度举高喷射消防车也将正式交付北京市消防局,为北京的消防安全保驾护航。

消防用水1000米一泵到顶

尽管各类消防车的举升高度不断刷新,但就目前的技术而言,消防车一般能抵达的最大高度为200米,超过200米的燃烧部分,只能通过建筑内部的固定灭火设备进行扑救,因此建筑物内部供水系统的可靠性至关重要。

然而,现行的离心水泵只能将水送至80米左右的高度,所以每隔80米左右,都要在建筑内设置泵房,以接力的方式将水运送到楼顶。发生火情时,如果停电或任何一部分管道出现问题,消防用水便很难运送到高处。

此次展会上,三一重工研发的全球首台超高压消防水泵首次亮相,虽然个头很小,但只需在楼内安装一条固定竖管,就可以保证1000米高楼消防供水一泵到顶,解决了目前超高层建筑的重大消防难题。

据悉,该套设备采用全液压柱塞泵组,输水压力达到12兆帕,双机组设备供水最大流量可达每分钟3000升,可以任意扩展设备实现流量的加大。此外,柴油机独立驱动的模式不依赖楼内电网,即使断电也能正常运行。

机器人可深入火场灭火

随着智能技术的应用,机器人开始在火灾中发挥重要作用。在消防展上,各类灭火机器人纷纷亮相,它们可以配合消防员更高效地开展灭火工作。

记者在展会上看到,一款防爆消防机器人个头不大,可以深入到火灾现场,自动寻找火源进行灭火。它的身上配置有红外热成像仪和彩色摄像头,可以采集和回传火灾现场多种环境信息,同时对有毒有害气体进行检测,将数据回传至后场的遥控器。更“能干”的灭火机器人还可以在火场寻找到燃气阀门并将其关闭。

无人机也逐渐应用在火灾救援中,起到侦察作用,一些无人机还可以凭借红外智能抛投系统,搭载绳索、药品等救援物资,为复杂、狭窄地形的救援提供支持。
