Technical Field

The invention relates to the technical field of fire extinguishing of unmanned aerial vehicles, in particular to a fire extinguishing system for a high-rise building of an unmanned aerial vehicle.

Background

With the rapid increase of high-rise and extra-high-rise buildings, the fire extinguishing and fighting problem of the high-rise buildings is increasingly severe, more than 6000 buildings at 120 meters in China already exist, and more than half of super-high-rise buildings in the world exist in China.

At present, the maximum height that fire control aerial ladder can reach is 110 meters, to the super high-rise building that these fire control aerial ladders can not be considered, the current method of initiatively putting out a fire through the outside mainly has two kinds, firstly utilize the high-accuracy point but putting out a fire of expensive fire-fighting guided missile to put out a fire, this method carries out with ground group vehicle-mounted remote launching's mode, like application number 2012100484453.2, a fire control unit that is applicable to high-rise and super high-rise building fire suppression, secondly along with unmanned aerial vehicle aerial launch remote fire extinguishing rocket that has developed along with unmanned aerial vehicle's technological progress in recent years, like application number 201710604649.8, unmanned fire extinguishing system of high altitude mooring and application number 201710604649.8, unmanned fire extinguishing system of high altitude mooring. Both ground grouped vehicle-mounted launched fire-extinguishing missiles and unmanned aerial vehicle aerial remote launched fire-extinguishing rocket missiles have problems. Firstly, the cost is too high, the fire rescue cost is difficult to bear, and for small products such as fire extinguishing bombs for high buildings, whether laser guidance or infrared guidance, the cost of accurately measuring and controlling each product is only about 3 ten thousand yuan, which can be negligible for the missile for military use, but means an unacceptable luxury price for the product for fire fighting use; secondly, the problems of projectile body strength, flight speed, precision required by hitting, and the like required by glass breaking are integrated, and the manufacturing difficulty and cost of the product are increased; thirdly, the risk of damaging the building body due to inaccurate shooting exists, no matter the fire-extinguishing missile is launched on the ground vehicle at a distance of more than one hundred meters, or the fire-extinguishing rocket missile is launched in the air by the unmanned aerial vehicle at a distance of more than ten meters, the possibility of not entering a window exists, and once the high-speed flying missile body required by 19mm safety glass is deflected, the building wall surface or the building body is damaged; fourthly, in order to meet the requirements of two work tasks of fire extinguishing bomb flight and window breaking, the power source of the fire extinguishing bomb is a small rocket engine, and the fire extinguishing bomb also brings high-temperature tail flame or a high-temperature engine into a fire scene while flying power, so that the possibility of igniting combustible materials in the fire scene is increased; fifthly, the fire extinguishing bomb is in an explosion spraying type, when the fire extinguishing bomb works, the explosive in the fire extinguishing bomb enables the fire extinguishing agent to be thrown to a fire scene, meanwhile, the shell of the fire extinguishing bomb is smashed, fragments of the shell of the fire extinguishing bomb are thrown to the fire scene together, and people waiting for rescue in the fire scene are injured; sixthly, the condition of card bullet appears easily as the guide rail when fire extinguishing bomb launches in the T shape slide rail, makes the fire extinguishing bomb can not break away from unmanned aerial vehicle, draws to turn over unmanned aerial vehicle or explode to turn over unmanned aerial vehicle, causes the unmanned aerial vehicle accident of falling.
