Description
Technical field
The invention belongs to unmanned plane fire-fighting technique fields, and in particular to a kind of six rotor unmanned plane and fire-extinguishing of single-shot.
Background technology
With the fast development of China's industrialization and urbanization process, 100 meters or more of skyscraper is on the increase, therewith
And the fire of high-rise building come happens occasionally.Due to story height, closeness is big and the factors shadow such as road and place limitation
It rings, traditional fire-fighting equipment such as motor ladder, giant and ground fire monitor is difficult effectively to send out when in face of fire of high-rise building
The effect of waving.Fire of high-rise building once will result in casualties and huge economic loss.For existing fire-fighting equipment
With the serious unbalance situation of fire of high-rise building, there is an urgent need for developing the novel fire extinguishing equipment that a kind of fire-fighting efficiency is high, mobility is good, with
Skyscraper is solved to put out a fire this global problem.
Application No. is a kind of tall-building fire fighting unmanned plane, including nobody are proposed in the innovation and creation of 2016101419566.X
Owner's body, camera and hydraulic giant carry hydraulic giant using unmanned plane and fly to high-altitude, and the water sprayed with hydraulic giant is put out a fire.The invention
The height of fire-fighting fire extinguishing operation, manoeuvrable can be improved by creating the unmanned plane proposed, but by the weight of hydraulic giant and its water pipe
Limitation, it is difficult to fly to too high floor.
It, should application No. is a kind of unmanned fire extinguishing system of high altitude kite balloon formula is proposed in 201720896766.1 innovation and creation
Invention combines the advantage for being tethered at unmanned plane and Extinguishing bomb, can put out a fire to skyscraper.But due to being tethered at nobody
For machine by cable power supply, the height that the length limitation of cable unmanned plane rises makes unmanned plane be difficult to reach very high floor.Together
When cable own wt limit the carry-on fire extinguisher bomb number of unmanned plane, fire-fighting efficiency is relatively low.
Application No. is proposing a kind of eight rotor high altitude firefighting unmanned plane and fire-extinguishings in 201710604634.1 innovation and creation,
The innovation and creation are flown to fire floor using unmanned plane carrying fire extinguisher bomb and are put out a fire by emitting fire extinguisher bomb, and routine is realized
The fire extinguishing of high building or superelevation building that fire-fighting equipment is unable to reach improves the single extinguishing ability of unmanned fire extinguishing system.But by
It is placed on body upper in fire extinguisher bomb, full machine center of gravity is higher, and the stability of unmanned plane is poor, can be made to the launch accuracy of fire extinguisher bomb
At influence.
It, should application No. is a kind of high building fire fighting unmanned plane and fire-extinguishing is proposed in 201810382139.5 innovation and creation
Innovation and creation, which by multi-rotor unmanned aerial vehicle carry more pieces of fire extinguisher bombs and rise to certain altitude, puts out a fire, and fire-fighting efficiency is high.But
Since its construction weight is heavier and it is more to carry fire extinguisher bomb quantity, cause unmanned plane take-off weight larger, power consumption is fast, cruise duration
It is short, it is difficult to it rises to higher floor and executes fire extinguishing task, and height big suitable for range on fire is not that very high floor is put out a fire,
It can be used for the very big inaccessiable forest extinguishing of personnel of range on fire；And unmanned plane layout is that half propeller is located at
Motor cabinet upper surface, half propeller are located at motor cabinet lower surface, and row is alternated positioned at the propeller of motor cabinet upper and lower surface
Cloth, although collision that such distribution form reduces the overall dimensions of unmanned plane, avoids propeller blade tip, but due to part
Paddle takes inventory the increase of the aerodynamic interference between overlap zone carrys out adjacent rotor so that pneumatic efficiency drastically reduces, finally so that fire-fighting
The flight time of UAV system greatly shortens.
Invention content

Six rotor unmanned plane and fire-extinguishing of single-shot it is small, it is light-weight, and horn is foldable, convenience in transport, can easily quickly exist
The building that catches fire nearby carries fire extinguisher bomb and takes off vertically and execute fire extinguishing task, solves existing fire-fighting equipment " into not going, open up not
Open, react slow " problem.
(3) use electromagnetic coil assist device, fire extinguisher bomb initial velocity high.
So that fire extinguisher bomb is obtained higher offtrack relocity, the guide rail that thrust is calculated is generated only according to fire extinguisher bomb itself gunpowder
Length is longer, and such unmanned plane overall dimensions can become larger, and in order to shorten rail length, using electromagnetic coil assist device, is going out
Fire makes fire extinguisher bomb first before playing propellant ignition there are one initial velocity, can reduce unmanned plane overall dimensions in this way.
(4) good environmental adaptability, fire accuracy are high.
Wind resistance is stablized under scene of a fire complexity air high turbulence environment of the unmanned plane and fire-extinguishing of the present invention between skyscraper building
Property is strong, can be with spot hover.In conjunction with it is pneumatic, promote, structure and the multiple subjects of ballistics, using integrated design optimization method,
Improve the stability and fire accuracy of fire extinguisher bomb trajectory.
