摘要
在分析了乌克兰SES单位的消防和救援发动机上的消防和技术设备,特别是灭火装置的存在后,我们建议,开发并构建了一种用于获得低频空气机械泡沫的喷嘴。这种喷嘴可以作为水和泡沫灭火剂的组合,以扑灭尚未发展到重要区域和规模的火灾。最好在火灾发生初期就将其扑灭,防止其危险因素对生物和环境的影响。鉴于上述问题,作者设计了一种能够完全停止灭火剂供应的喷嘴,使用带手柄的高架起重机。在消防喷嘴出口处安装由1.5 x 1.5 mm管组成的金属网。喷嘴的外壳两侧装有橡胶保护层,这将保护救援人员免受可能的电击。使用这种喷嘴可以更有效地消除火灾和更经济地使用灭火剂。该技术特性对于后续设备的成功使用是可接受的。此外,其优点之一是在灭火过程中,如果救援人员的位置发生变化,可以停止灭火物质的输送,减少水和泡沫的流动,并防止可能的电击。
DEVELOPING OF BLOCKING NOZZLE FOR COMPLEX EXTINGUISHING ON THE INITIAL STAGE OF FIRE
After analyzing the presence of fire and technical equipment, in particular fire extinguishing devices, on the fire and rescue engines of the SES of Ukraineunits, we have suggested, developed and constructed a nozzle for obtaining low-frequency air-mechanical foam. This nozzle can serve as a combination of water and foam extinguishing agents to extinguish fires that have not developed into significant areas and sizes.It is preferable to eliminate the fire at the initial stage of its occurrence, preventing the influence of the effects of its dangerous factors on living creatures and the environment.
Given the above problem, the authors designed a nozzle with the ability to completely cease the supply of extinguishing agents, using an overhead crane with a handle.At the exit from the fire nozzle, a metal mesh consisting of 1,5 x 1,5 mm tubes is installed. The shell of the nozzle is equipped with rubber overlays on both sides, which will protect arescuer from possible electric shock.
The use of such nozzle allows for more efficient elimination of fires and more economical use of extinguishing agents. The technical characteristics are acceptable for the subsequent successful use of the device as intended. Additionally, one of the advantages is the possibility of ceasing the delivery of extinguishing substances in case of changing the position of a rescuer during the elimination of fire, reducing the flow of water and foam, as well as protection against possible electric shock.
