Description
Technical Field
The utility model relates to a super high-rise building fire prevention equipment technical field that disappears especially relates to a compressed air foam unmanned helicopter of putting out a fire.
Background
At present, the domestic fire-fighting unmanned aerial vehicle capable of extinguishing fire is mainly used for fire extinguishing in super high-rise buildings and forest. Along with the urbanization construction, super high-rise buildings are more and more, the height of a plurality of super high-rise buildings exceeds the working limit height of ground fire-fighting equipment, and once a fire disaster happens, self rescue can only be realized by people in the buildings. Fire control unmanned aerial vehicle can realize taking off and land fast, effectively solves the fire extinguishing problem of super high-rise building conflagration.
However, there are also the following problems:
1. load problem of unmanned aerial vehicle
If conflagration breaks out in the city, the unmanned aerial vehicle of certain only rotor can be fast and accurate hover and put out a fire in the conflagration place. However, the general load capacity of the existing large-scale multi-rotor unmanned aerial vehicle (the weight of the empty aircraft is more than or equal to 7kg) is within 20 kg. At most, only a few fire extinguishing bombs or a bottle of dry powder extinguishing agent can be carried.
2. Endurance problem of unmanned aerial vehicle
At present, unmanned aerial vehicles with strong cruising ability on the market are generally fixed-wing, but fixed-wing aircrafts cannot hover to extinguish fire within a certain range. Therefore, the unmanned aerial vehicle of putting out a fire on the market at present mostly adopts many rotor unmanned aerial vehicle, but, many rotor unmanned aerial vehicle's time of endurance is shorter, can not put out a fire for a long time.
3. Problem of low fire extinguishing efficiency of fire extinguishing agent carried by unmanned aerial vehicle
At present, the mode that the unmanned aerial vehicle of putting out a fire on the market mostly adopted the transmission fire extinguishing bomb or sprayed the powder of putting out a fire is put out a fire. The fire extinguishing bomb and the fire extinguishing powder are essentially dry powder fire extinguishing agents, and the dry powder fire extinguishing agents are low in fire extinguishing efficiency, poor in cooling effect, easy to reburn, incapable of rapidly permeating fire objects with complex structures, difficult to clean a large amount of dust and secondary pollution to fire objects. In addition, because the restriction of carrier, the dry powder fire extinguishing agent volume that unmanned aerial vehicle carried is limited, to slightly bigger type conflagration, hardly effective control condition of a fire.
Compressed air foam is a globally accepted high-efficiency fire extinguishing agent at present, and the fire extinguishing efficiency of the compressed air foam is 4-5 times that of the traditional foam and 7-10 times that of water. The compressed air foam has strong adhesiveness, has good adhesion effect on a vertical smooth surface, and can effectively extinguish fire and continuously insulate heat and cool. The compressed air foam is a film-shaped foam group generated by mutually mixing foam liquid, water and air through mechanical action. The gas in the bubbles is air, and the compressed air foam extinguishing agent has the function of preventing the steam of the flammable or combustible liquid from entering a flame zone after the compressed air foam extinguishing agent covers the surface of the flammable or combustible liquid by a certain thickness, so that the air is isolated from the liquid level, and the heat in the flame zone is prevented from entering the surface of the flammable or combustible liquid.
An unmanned helicopter is a vertical take-off and landing (VTOL) unmanned aerial vehicle flying by radio ground remote control or/and autonomous control, belonging to a rotary wing vehicle in a structural form and a vertical take-off and landing vehicle in a function. The unmanned helicopter has unique flight performance and use value. Compared with the existing helicopters, the unmanned helicopters have incomparable superiority in many aspects due to the characteristics of no casualties, small volume, low cost, strong battlefield viability and the like. Compared with a fixed wing unmanned aerial vehicle, the unmanned helicopter can take off and land vertically and hover in the air, flies in any direction, has a small take-off and landing field, and does not need to be provided with a complicated and large-volume launching and recovering system like the fixed wing unmanned aerial vehicle. Compared with a multi-rotor unmanned aerial vehicle, the unmanned helicopter has large task load and can carry more fire extinguishing agents. Because the unmanned helicopter adopts the gasoline engine, the unmanned helicopter has long endurance time and can extinguish fire for a long time under the condition of carrying sufficient fuel.
Based on the above statement, how to design a compressed air foam unmanned helicopter of putting out a fire is the utility model discloses the technical problem that will solve.
