Some specific implementations are described below.
The fire engine adopts a lifting fire engine with the lifting capacity of 45 meters, the fire engine is provided with a three-axle chassis, and the overall dimension is less than or equal to 12.5 meters when the whole vehicle is in a running state. The fire engine is loaded with two fire extinguishing agents, namely water and foam concentrate. The drift diameter of the fire extinguishing agent conveying pipeline of the elevating fire truck is more than or equal to 80mm. On-vehicle unmanned aerial vehicle is many rotor electric unmanned aerial vehicle, has 50 Kg's carrying capacity. The foam expansion ratio is set to 6 to 8. The unmanned aerial vehicle pulls the water hose 6 with the length of 100 meters, the drift diameter of the water hose 6 is 50mm, and the fire fighting of the high-rise building with the height of 120 meters and the span of 30 meters can be realized. The water belt weight of the water belt 6 is 150g/m.
The first working mode is a fire truck lifting fire extinguishing mode. Aiming at high-rise fire of below 60 meters, the fire monitor 14 sprays a large-flow fire extinguishing agent of which the volume is more than or equal to 60 liters/second (water) or more than or equal to 120 liters/second (compressed air foam, the foaming multiple is 6-8 times) to extinguish the fire mainly through a water-foam dual-purpose fire monitor at the head end of the elevating fire truck. In this state, the boom 7 can normally change its amplitude, and the limit curve S1 of the safe working range in the uplift fire-extinguishing mode is shown in fig. 5 and 6. In fig. 5, the working height refers to the height relative to the ground. The working range refers to the distance of the fire engine from the building to be extinguished in the horizontal direction.
The second working mode is coupled unmanned aerial vehicle extinguishment. Aiming at high-rise fire of more than 60 meters, the fire fighting truck is coupled with the unmanned aerial vehicle to operate in a fire fighting mode. Under this mode, drag hosepipe 6 through unmanned aerial vehicle, with the help of the fire extinguishing agent preparation and the conveying system supply of elevating the fire engine, through unmanned aerial vehicle's fire extinguishing agent injection apparatus 3, the injection is not less than 18 liters/second (compressed air foam, the multiple of foaming is 6 ~ 8 times) the small flow fire extinguishing agent rises to the near-fire source puts out a fire. In this case, the boom 7 no longer operates, and the position of the fire monitor 14 is within the range indicated by the safe operation range curve S2 in fig. 5 and 6, which are both considered to satisfy the position requirement of the unmanned aerial vehicle before takeoff.
The specific operation method for the coupled unmanned aerial vehicle fire extinguishing mode operation comprises the following steps: firstly, the operation arm support 7 reaches a standard working attitude required by the operation of the coupling unmanned aerial vehicle through the main control platform 10 of the elevating fire truck. The small-range limit curve S2 in the standard working posture is required to be within the limit curve S1 of the safe working range in the elevating fire-extinguishing mode during coupling operation, which mainly considers that the tilting moment is larger during coupling operation. Then, press the mode switch button, make it in coupling unmanned aerial vehicle mode of putting out a fire. Secondly, operating the unmanned aerial vehicle console 11, and opening a bottom plate of the storage device 12 and a bypass valve at the transfer pipeline 15; then the overlapped part of the water belt 6 falls and expands under the self gravity; subsequently, the drone is steered to take off and hover from the support platform 8, see fig. 6 where the drone is located on the right. Then, the compressed air foam system 16 of the elevating fire truck is operated to enable the unmanned aerial vehicle spraying device 2 to spray wet foam, and then the multi-rotor unmanned aerial vehicle is operated to fly to a near-to-rescue target to extinguish fire. Finally, when unmanned aerial vehicle accomplished the operation of putting out a fire, the operator controls platform 11 through unmanned aerial vehicle, opens the automatically controlled locking device 33 of the connection ultralight hosepipe interface of transfer pipeline department, and the automatically controlled locking device 33 that is located the lower extreme that introduces above promptly operates unmanned aerial vehicle and pulls hosepipe 6 and descend to ground.
