Along with the continuous development of society and the continuous increase of urbanization population density, the urban construction of China is in a leap-type development stage, super-high, super-large and super-wide building bodies begin to emerge continuously, and the fire safety hidden danger brought by high-rise buildings is increased year by year while the urban image is shaped and the living quality of people is improved. Because the super-high, super-large and super-wide building body has more personnel and is difficult to evacuate during fire, combustible substances and inflammable substances are relatively concentrated, the fire load is large, and various vertical well problems such as stairwell, piping shaft and the like exist in a high-rise building, once the fire breaks out, the fire can rapidly spread to the horizontal direction and the vertical direction, and great difficulty is brought to fire fighting. On the other hand, a water spraying fire extinguishing system is not arranged in the old building, the outer wall of the old building is generally made of flammable heat-insulating materials, once the old building catches fire, the old building can only be put out on the spot by fire rescue, the best opportunity of missing fire rescue is caused, and serious fire casualties with group death and group injury occur occasionally, so that a fire extinguishing device and a fire extinguishing operation method for the old building are urgently needed to be researched.
At present, a high-rise fire extinguishing and rescuing device mainly comprises a lifting jet fire truck, but the effective range height of the device is generally less than 60 meters, the problems that the higher the fire floor is, the more difficult the water pressure is to reach, and the like exist, the fire extinguishing of buildings at the fire-starting positions of more than 60 meters is difficult, and the fire of the super-high buildings can not be effectively extinguished. On the other hand, the existing height-lifting jet fire truck has huge volume and poor maneuverability, is influenced by a plurality of factors such as obstacles around a high-rise building, and the like, so that the due effect cannot be quickly exerted under the condition of a fire disaster, the situation is out of control, and serious casualties such as escape of trapped people inside the building and the like can be caused along with further spread of the fire. Therefore, at present, a fire extinguishing and rescuing device capable of quickly extinguishing the initial fire on the outer wall of the high-rise building is urgently needed to be researched, and the practical problem that the existing fire truck is difficult to extinguish the fire more than 60 meters is solved.
Chinese patent CN204723656U discloses a spray arm structure installed in a high-rise building, which has a major problem that the spray arm structure needs to occupy a certain indoor space when installed in the building. In addition, the water spraying arm of the patent only has a good extinguishing effect on indoor fire on the same floor with the water spraying arm, and can only extinguish the fire on the outer vertical surface even if the water spraying arm penetrates through the indoor wall arm and extends out of the window for indoor fire on other floors, and the water spraying arm cannot effectively extinguish the indoor fire on other floors. Therefore, the practicability of the fire extinguishing device is not high enough, the fire extinguishing device is not beneficial to wide popularization and application, and the fire extinguishing range and the extinguishing capability are both limited.
