To achieve these goals, the technical solution used in the present invention is:
A kind of spraying operation system of rotor class aircraft, liquid reserve tank 1 bottom is provided with water connection, water connection is connected with miniature electronic water pump 4 use pipelines 2, valve 3 is installed in the middle of pipeline, miniature electronic water pump 4 is provided with a switch 9 and is arranged on instrument desk, miniature electronic water delivery side of pump is connected with high-speed joint 5 with pipeline 2, high-speed joint 5 is arranged on the lower end of the hollow spindle 6 of rotor head, the cross-drilled hole outside of hollow spindle 6 upper ends is provided with joint, be connected with the hole of rotor 7 roots with holes by pipeline 2, rotor wing tip with holes place is provided with adjustable shower nozzle 8.
Described system is that the centnifugal force that utilizes rotor wing rotation to produce sprays liquid from wing tip, without any engine installation of extra increase.
Described system is adapted at using on any rotor class aircraft.
The application of described operating system, take off and arrive after operating location, open miniature electronic water pump by button, make liquid arrive shower nozzle by pipeline, because rotor is at High Rotation Speed, the liquid entering in rotor pipeline also sprays because the effect of centripetal force is thrown toward shower nozzle direction, once starting ejection, liquid just can turn off miniature electronic water pump, the centnifugal force that utilizes rotor wing rotation to produce makes the continual ejection of liquid, liquid in liquid reserve tank is because siphon principle can be inhaled in rotor pipeline by nature, because line speed is very fast before aircraft, the liquid of ejection also has little time to drop on fuselage, aircraft flies all the time and can not pollute to fuselage in the front of ejection liquid, this design has utilized centnifugal force and the siphon principle of rotor cleverly, thereby complete sprinkling without any need for additional power, and beyond fuselage, can not increase any equipment and affect safety.
Wherein, liquid reserve tank: store and do the required liquid of industry;
Pipeline: carry liquid to shower nozzle while doing industry
Valve: do the complete cut-out liquid flowing pipe of industry road
Miniature electronic water pump: open electronic water pump while starting to do industry liquid is pumped into Pipeline transport to shower nozzle, make to be full of liquid in pipeline, the condition of siphon is provided to the rotor of High Rotation Speed.
High-speed joint: because the part of pipeline below from liquid reserve tank to rotor head main shaft is static with respect to airframe, and liquid need to be delivered in the rotor pipeline of High Rotation Speed, the effect of high-speed joint is exactly the hollow rotor head main shaft that connects static pipeline and High Rotation Speed, makes liquid to be delivered to shower nozzle smoothly and can not reveal.
Rotor head hollow spindle: liquid needs a passage to enter the pipeline of rotor from fuselage, and this passage is exactly rotor head hollow spindle
Rotor with holes: liquid needs a passage to enter the shower nozzle of rotor point from fuselage, and this passage is exactly the adjustable shower nozzle of rotor with holes
Pump switch: for starting and stop miniature electronic water pump
The liquid spraying system that rotor class aircraft is special, comprises liquid reserve tank, pipeline, is valve, is miniature electronic water pump, high-speed joint, hollow spindle, rotor with holes, nozzle adjustable, switch.
Connecting line on liquid reserve tank, mounted valve and electronic water pump on pipeline, the coolant outlet pipe of water pump is guided mast below into, Quick rotary joint is installed below mast, the top of joint is connected with the main shaft of aircraft rotary wing, main shaft is hollow shaft, and being provided with transverse holes in rotor position communicates with spindle hole, the transverse holes outside of main shaft is provided with the joint of connecting hose, the main body of rotor is provided with a hole of leading to rotor point from rotary-wing root section, inner side, hole is provided with an anti-corrosion pipeline and leads to wing tip, and the outlet that wing tip portals is provided with adjustable shower nozzle.
beneficial effect:
1, safe, simple to operate;
2, equipment package is no more than 500 grams, increases hardly the weight of aircraft;
3, stability is high, and wind resistance is strong, does not change the original pneumatic design of aircraft;
4, device structure is simple, working stability, and cost is very low, and cost performance is very high.
