Embodiment 1

[0026]An unmanned helicopter 1 with a carrying capacity of 70kg drags an ultra-light hose 3 with a diameter of 40mm and a length of 2m, and flies to the fire scene under the control of a wireless remote control device 8 and a Beidou navigation / gyro stabilization mechanism 1-2, and a camera 1- 1 shows obstacles on the way. The helicopter 1 hovers near the compressed air foam fire engine 5, and the lower end hose quick-release interface 4 of the ultra-light hose 3 towed by it is 2m in length, and the height from the ground is 1-1.5m. The ultra-light hose 3 of the foam fire truck 5 is connected with the hose quick release interface 4 towed by the unmanned helicopter 1 . Thereafter, the compressed air foam fire truck 5 inputs pressure into the ultra-light hose 3 and is a Class A foam fire extinguishing agent with a pressure of 1.2MPa. When the mixing ratio of Class A foam fire extinguishing agent and water is adjusted between 0.2% and 0.6%, the expansion ratio of the correspondin...

Embodiment 2

[0029] The carrying capacity is the unmanned helicopter 1 of 70kg, the ultralight hose 3 that the diameter of towing is 50mm and length is 2m, as described in embodiment 1, flies to the suspension near the compressed air foam fire truck 5 under the control of the wireless remote control device 8. Stop, the length of the ultra-light hose 3 dragged by it is 2m, the lower end hose quick-release interface 4 is 1-1.5m above the ground, and the firefighters will use the ultra-light hose 3 and The water belt quick release interface 4 towed by the unmanned helicopter is connected. Thereafter, the compressed air foam fire engine 5 inputs a Class A foam fire extinguishing agent with a pressure of 1.2 MPa and a foaming rate of 10 times into the ultralight hose 3, and the unmanned helicopter 1 drags the ultralight hose 3 to spray Class A foam fire extinguishing Agent edge lifts into the air (to avoid the influence of the recoil force that produces when the air is turned on and sprayed on ...

Abstract

The invention discloses a method and device for using unmanned helicopters to put out fires in high-rise buildings. The device comprises a water hose, a foam extinguishing agent spraying pipe, a compressed air fire-extinguishing foam tanker, a wireless remote control device and at least one unmanned helicopter, wherein the foam extinguishing agent spraying pipe is fixed below each unmanned helicopter, one end of the water hose is connected with the inlet end of the foam extinguishing agent spraying pipe, the other end of the water hose is connected with class-A foam extinguishing agent spraying pipe outlets of the compressed air fire-extinguishing foam tanker, and the wireless remote control device is used for operating the unmanned helicopters to conduct lift-off operation. The unmanned helicopters drag the class-A foam extinguishing water hose to lift off and put out fires in the high-rise buildings, and the method and device have the advantages that the reaction speed is high, the lift-off height is high, the working range is wide, and multiple machines can achieve interconnected operation. By means of the method and device, the efficiency of putting out the fires in the high-rise buildings can be greatly improved.

Description

technical field [0001] The invention belongs to the field of fire-fighting equipment, in particular to a method and device for fire fighting of high-rise buildings by unmanned helicopters. Background technique [0002] my country's cities are full of high-rise buildings. The characteristics of fire fighting in high-rise buildings are that the fire expands quickly to the upper space, and the burning range expands rapidly. The upward climbing passage inside the high-rise building is narrow, and it is difficult to transport personnel and fire-fighting equipment up. Plagued by high-temperature smoke, it is very difficult for firefighters to attack the fire from inside. The elevating jet fire truck used to spray water outside the building is not conducive to rapid maneuvering in the congested roads of the city because the body is too long, and the area outside the building where the fire is on fire is narrow, so the elevating jet fire truck is not easy to deploy, and the lifting...
