Description
Technical Field
The invention belongs to the technical field of fire fighting, and particularly relates to a fire extinguishing system and method for a high-rise building.
Background
The major problem threatening the safety of high-rise buildings is fire disasters, once the fire disasters occur, irreparable consequences can be caused due to the characteristics of the high-rise buildings, and at present, the fundamental cause of serious fire disasters of urban residences in China is the great difficulty and challenge of fire fighting. On one hand, the whole country has 34.7 ten thousand high-rise buildings with more than 8 floors and more than 24 meters, and 6000 super-high buildings with more than one hundred meters, and the number of the buildings is the first in the world. The traditional high-pressure water gun, the aerial ladder vehicle or the traditional unmanned aerial vehicle are still adopted in the existing fire fighting equipment for fire extinguishing means of high-rise buildings, and most of fire fighting elevating vehicles and fire fighting water guns can only spray the fire fighting water guns to the height of 50 meters at most. If the fire fighter climbs the building with a load and exceeds 20 floors, the physical strength is consumed, and the rescue action cannot be effectively carried out. Once a fire disaster occurs in a high-rise building, except for utilizing internal fire-fighting facilities, a more effective means for extinguishing the fire is not available, and the traditional fire-fighting means has the following technical defects: (1) the floor is higher, and climbing is difficult; (2) few evacuation ways and great evacuation difficulty; (3) Fire-fighting rescue equipment is greatly restricted, the existing fire-fighting vehicle equipment in part of areas can hardly meet the requirements of fire-fighting rescue tasks of high-rise buildings, and special fire-fighting vehicles such as aerial ladder fire trucks and the like can only be close to fire areas with corresponding heights to extinguish fire; and (4) lack of ascending equipment.
Therefore, a means which can ascend quickly, is flexible in deployment and convenient and fast to operate is urgently needed to be found, and the pain points can be effectively solved so as to deal with the fire suppression of high-rise buildings. Further, the selection of a multi-rotor unmanned aerial vehicle which is smaller in size and cost than a manned aircraft, can hover in the air, and can be deployed quickly to extinguish fires in high-rise buildings is a good way naturally. The appearance of the mooring unmanned aerial vehicle enables the problem that the endurance time of the common electric or oil-driven multi-rotor fire-extinguishing unmanned aerial vehicle is limited fundamentally to be effectively solved. The tethered unmanned aerial vehicle is a tethered multi-rotor unmanned aerial vehicle device connected with a ground power supply system through a photoelectric composite cable to obtain uninterrupted energy. However, the technical solutions of the prior art for applying the captive robot in the field of fire fighting still have the following typical technical defects:
(1) The foam fire extinguishing tank is suspended on the aerial operation subsystem, so that the load of the unmanned aerial vehicle is increased, and the fire extinguishing agent cannot be continuously supplied for a long time, so that the fire extinguishing efficiency is influenced;
(2) The technical means for keeping the flight balance under the fire extinguishing operation state is lacked, so that the fire extinguishing operation is accurately and continuously carried out; for example, the recoil caused by the large amount of sprayed fire extinguishing agent to the air working subsystem is not treated;
(3) The fire extinguishing can plus the spray gun is adopted to extinguish fire, and due to the lack of necessary regulation and control means, the fire extinguishing agent sprayed by the spray gun is difficult to accurately align to a fire point or align to the fire point through a rapid adjustment system;
(4) Unmanned aerial vehicle carries the roof and wastes time and energy, lacks the auxiliary means.
In view of the foregoing, there is a need to provide a more efficient fire suppression system and method for high-rise buildings that addresses the deficiencies of the prior art.
