In the past, fire-fighting officers and soldiers have continuously increased casualties due to the fact that fire-fighting equipment of high-rise buildings lags behind and explosive cases are treated in a close range in the fire-fighting process, and the fire-fighting problem is not solved. At present, aerial ladder fire trucks are mostly adopted to solve the problem of high-rise fire fighting, and the common aerial ladder fire trucks have the effective operation height of 30-50 meters and the height of 60-70 meters. However, the fire truck is limited by the normal degree of the street when the fire truck is out of police and fighting fire due to large volume, is difficult to pass through the narrow street, and often cannot arrive at the fire scene in the first time, so that the fire is further worsened.
Once a fire occurs in a high-rise building, a remarkable characteristic is the chimney effect, namely: the hot air from a fire occurring at the bottom floor, because of its lower density, flows through the elevator shaft or through the stairway in a mesh, like the air flow in a large chimney, causing the hot gases to accumulate continuously at the top of the shaft, with the result that the fire creates another fire scene at the top floor of the building through convection of this air. Furthermore, as the hot air is exhausted, fresh air is continuously sucked in from the bottom flow path, which further increases the fire. The fire disaster mostly spreads along an elevator slot or a corridor passage, and fire fighters can not extinguish the fire from the outside like processing the fire disaster of a common building, only wear an air respirator to enter a fire scene, and attack and fight the big fire through the inside. However, in these narrow areas, the fire extinguishing apparatus cannot operate effectively, and once a fire spreads to a high-rise floor, a firefighter cannot carry the fire extinguishing apparatus to put out a fire, which brings great difficulty to rescue work.

when the spray pipe 4 is inserted into the locking cylinder 33, the projection 42 enters the first guide groove 336 through the mounting hole 339, then the projection 42 moves forwards to press the baffle 333 against the elastic force of the first spring 332, when the projection 42 is separated from the first guide groove 336, the spray pipe 4 is rotated, and at the moment, the projection 42 can rotate to the second guide groove 337 and is pressed into the second guide groove 337 under the action of the baffle 333, so that the spray pipe 4 can be quickly mounted through the arrangement of the projection 42, the first guide groove 336 and the second guide groove 337, the mounting efficiency is improved, and precious time is saved for fire extinguishing and disaster relief; meanwhile, due to the extrusion of the first spring 332 and the baffle 333, the projection 42 cannot slide out of the second guide groove 337, so that the stable connection between the spray pipe 4 and the locking barrel is ensured, and the safety is improved; in addition, because the opening direction of the second guide groove 337 faces one side of the auxiliary sleeve 23, when the spray pipe 4 is sprayed, the spray pipe 4 will move to the inner side of the second guide groove 337 under the action of recoil force, so that the spray pipe 4 will not be separated from the locking cylinder 33, further improving the safety during operation; the second spring 338 can provide partial clamping force to limit the movement of the bump 42, so that the situation that the bump 42 moves back and forth in the second guide groove 337 to cause the water spraying pipe 4 to shake back and forth to influence the flight stability of the unmanned aerial vehicle body is avoided; meanwhile, the second spring 338 can also timely digest impact energy caused by recoil when the spray pipe 4 sprays water, so as to achieve a better shock absorption effect; through the arrangement of the rubber strips 53, when the water spray pipe 4 sprays water, impact energy can be reduced through two modes of friction and elastic deformation, the flight stability of the unmanned aerial vehicle body is greatly improved, and the situation that the unmanned aerial vehicle body loses balance due to recoil and even falls down is avoided; through the arrangement of the elastic rope 5, on one hand, the elastic rope 5 can hinder the movement of the bump 42 after the second spring 338 is compressed, that is, after the second spring 338 is compressed to achieve the first shock absorption, the elastic rope 5 performs the second shock absorption on the bump 42 through the elasticity of the elastic rope 5; on the other hand, the elastic rope 5 can also enable the rubber strips 53 to be close to each other and extrude through tensioning of the elastic rope, so that the pressure of the rubber strips 53 on the outer surface of the water spraying pipe 4 is increased, and the three-time shock absorption of the water spraying pipe 4 is realized through improving the friction energy consumption mode, so that a better shock absorption effect is achieved.
