Description
Technical field
The present invention relates to fire station field, and in particular to a kind of flight fire station.
Background technology
Existing fire fighting truck does not have effective saving method due to the limited height elevated for high-rise fire, so very
Many producers all are wanting to launch fire extinguisher bomb by ground either unmanned plane to put out a fire, but are wanted because transmitter has to fire extinguisher bomb weight
Ask, so the dry powder limit of bullet band is limited, bullet enters not necessarily just to explode around fire point within doors, while the blast production of bullet
Raw shell fragment is easily damaged to personnel.
Aircraft is when putting into flight bullet in the room of high level, and aircraft hovers in the air, using traditional shell
Transmitting, moment produces very big recoil, causes flight unstable, and shell is not easy to aim at, and influences actual extinguishing effect.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of flight fire station, and flight lift is big, flight temperature so that
Accuracy of putting out a fire is improved, and the moment recoil of fire-extinguishing gun is small, fire-extinguishing gun sustained firing, and the flight interference to aircraft is small, flies
Row device is also easier to keep floating state, and concrete technical scheme is as follows：
A kind of flight fire station, including aircraft and fire-extinguishing gun, the fire-extinguishing gun carry is on the aircraft；
The aircraft is multi-rotor aerocraft, and the aircraft includes fuselage, engine, horn and double oar rotors, institute
Engine is stated on the fuselage, double oar rotors, the horn more than one, and each institute described in the engine driving
State horn to be fixed on the fuselage, each described pair of oar rotor is individually fixed on each described horn；
The radiation pattern of the fire-extinguishing gun is sustained firing mode.
Further limit, the described pair of oar rotor includes upper propeller and the lower propeller, the upper propeller and described
On the same axis, and the upper propeller and the lower propeller are respectively positioned at the horn for the pivot of lower propeller
Both sides up and down, the upper propeller is variable-pitch propeller.
What the present invention was realized in：Aircraft carry fire-extinguishing gun, Wireless remote control flying device is flown into the air so that gun muzzle pair
Then the position that fire occurs, control aircraft hovering controls fire-extinguishing gun to spray the extinguishing chemical of powdery, and double oar rotors of flight are real
When adjustment position, with adapt to fire-extinguishing gun generation recoil, it is ensured that the accuracy of injection.Upper propeller is variable-pitch propeller, is made
The flight conversion for obtaining aircraft adjusts more flexible, the setting of lower propeller, improves the lift of aircraft.
A kind of restriction of concomitant regimen, the lower propeller is variable-pitch propeller.
Flexibility is good, and wind loading rating is strong.
A kind of restriction of concomitant regimen, the lower propeller is constant pitch airscrew.
Flight stability, lower propeller provides stable lift.
Further limit, the engine output end is installed with drive bevel gear, and the drive bevel gear passes through power transmission shaft
Power is transmitted to described pair of oar rotor, the power transmission shaft two ends are bevel gear structure, the power transmission shaft and the drive bevel gear
Engagement, the multiple power transmission shafts of the drive bevel gear correspondence.
Realize one drive bevel gear of an engine driving, the multiple power transmission shafts of active conical tooth wheel drive so that
Multiple pairs of oar rotors reduce the number of engine by an engine driving, and structure is simplified, and alleviate the weight of engine
Measure, and the synchronism of the velocity of rotation of double oar rotors on each horn is good, relatively reliable stabilization of flying.
A kind of restriction of parallel technical solution, the upper propeller is driven by upper rotor shaft, solid in the upper rotor shaft
Be cased with bevel gear, the lower propeller is driven by lower rotor shaft, be installed with lower bevel gear in the upper rotor shaft, it is described on
Rotor shaft and the lower rotor shaft are set and on the same axis every sky, the upper bevel gear and the lower bevel gear and same
The power transmission shaft engagement.
The reverse rotation of propeller and lower propeller is realized, the corner power that horn is born, the intensity of horn is reduced
It is required that reduction, so that manufacturing cost is reduced, while the reliability of flight is also higher.
A kind of restriction of parallel technical solution, the upper propeller and the lower propeller are driven by a public rotor shaft
Dynamic, the upper propeller and the lower propeller are solidly set in the two ends of the public rotor shaft, the public rotor shaft respectively
It is installed with public bevel gear, the public bevel gear and power transmission shaft engagement.
The synchronization for realizing propeller and lower propeller rotates in same direction, and reduces a bevel gear, alleviates aircraft
Weight, so as to increase the weight of carry.
Further limit, the fire-extinguishing gun includes gun tube, dress powder case and line pressure source, the gun tube and the dress powder case are solid
It is scheduled on the lower section of the fuselage；

Connection, the gun tube and the dress powder case junction are interflow fork, and the line pressure source is fixedly mounted on the big gun of the gun tube
On tail, and the line pressure source is connected with the gun tube；
The dress powder box top is provided with drive powder forcing pipe.
The sustained firing of fire-extinguishing gun is realized, moment recoil is reduced so that the flight stability of aircraft is improved so that
Point occurs for the fiery residence of alignment also more accurately, by driving powder forcing pipe so that the powdery extinguishing chemical in dress powder case can be smooth
It is pressed into gun tube, and forced air is ejected together.
Further limit, the drive powder forcing pipe connection secondary stress source.
Secondary stress source is separately configured, the squeeze pressure to powdery extinguishing chemical can be accurately controlled.
Further limit, the drive powder forcing pipe is connected with the gun tube, the gun tube and drive powder forcing pipe connection
Locate to shunt fork, the shunting fork is located between the interflow fork and the breech.
Reduce a secondary stress source so that the overall weight of flight fire station reduces.
Further limit, the communicating passage of the dress powder case and the gun tube is provided with traffic controller, the flow control
Making sheet blocks the communicating passage of the dress powder case and the gun tube, and the traffic controller plate passes through flow servo driving.
The folding degree of servo driving traffic controller, realizes the control to powdery extinguishing chemical uninterrupted, to adapt to not
Same fire hazard situation.
Beneficial effects of the present invention are：Launched by the sustained firing mode of fire-extinguishing gun, reduce moment recoil so that
The flight stability of aircraft is improved, so that fire-extinguishing gun is more easily aligned burning things which may cause a fire disaster；It is variable-pitch propeller by upper propeller
Structure, and lower propeller setting so that the delivery efficiency of engine uprise there is provided lift it is bigger, the stability of flight
Also it is more preferable；Set by the spacing of lower propeller, it is ensured that flight stability；It is displacement spiral shell by upper propeller and lower propeller
The setting of oar is revolved, the displacement pressure because single-blade displacement system is reduced, while up and down can be with displacement so that flight is more
Flexibly；Reversely rotated by upper propeller and lower propeller, and by same transmission shaft driven, on the one hand reduce horn
Corner power, another aspect drive mechanism is simplified, and the weight of aircraft is mitigated；In summary, the weight of aircraft is subtracted
Gently, while flight flexibility and lifting capacity get a promotion.
