Description
Technical field
The present invention relates to aircraft technical field more particularly to paddle components and aviation atomization systems.
Background technique
Agricultural aircraft aerial pesticide has flying speed fast, and spraying operation is high-efficient, and it is excellent that reply burst fire-disaster ability is strong etc.
Point receives great attention in agricultural plant protection field.In recent years, in the big of China's agricultural modernization growth requirement and national policy
It pushes under moving, China's agricultural aviation pesticide application technology is quickly grown, and is more widely applied.
Aerial pesticide sprays instrument and Crop spatial spacing is larger compared with area spray mode, is administered droplet by surrounding
The factors such as ambient temperature and humidity, wind field are affected.To improve pesticide utilization rate, improving deposition matter of the spray liquor on crop
Amount reduces pesticide drift, therefore the aviation of specific pesticide has sprayed specific mist droplet particle size size requirement.Atomizer is to realize
The capital equipment of pesticide atomization, current atomizer mainly have pressure-type atomizer and two kinds of centrifugal type atomizer.Pressure-type atomization
Device is poor by spray liquor piping and the external space pressure of pipeline, realizes the atomization to pesticide.This atomizer is to atomization medical fluid
The controlling of droplet sizes is poor, and atomization medical fluid mist droplet particle size span is big and consistency is poor.It is carried out when using this kind of atomizer
When aerial pesticide, medical fluid drift is serious, easily the pollution of generation Pesticide environment.Centrifugal type atomizer be by by centrifugal turntable or
It is centrifuged atomization of the rotating cage realization to medical fluid, the controllability of the atomization mist droplet particle size of the type atomizer is larger, and atomization droplet is consistent
Property it is preferable, relatively be suitable for aerial pesticide.But it still exists that atomizer nebulization efficiency is low, the non-uniform problem of droplet sizes.
There are no manned aircrafts with independent intellectual property rights to be administered dedicated centrifugal atomizer so far in China.When
Before, manned large aircraft application mostly uses pneumatic rotating cage type centrifugal atomizer.This kind of atomizer is with Britain Micronair
The product of (Coudé is precious) company is applied more at home.The atomizer has the advantages that centrifugal type atomizer, but simultaneously with boat
The demand of sky application facility modernization, drawback also gradually show, and are mainly reflected in following aspect:
The type atomizer by driving blade by the high-speed flow in aircraft flight, revolve by paddle belt turn cage high speed
Turn to realize the atomization to medical fluid.When rotating cage output medicinal liquid flow is consistent, rotating cage rotation speed is faster, and atomizing effect is stronger, mist
It is smaller to change mist droplet particle size；Rotating cage rotation speed is slower, then atomizing effect is weaker, and atomization mist droplet particle size is bigger.Aircraft flight speed
Difference, the air stream drives power that blade is subject to is different, and then leads to rotating cage revolving speed difference, medical liquid atomizing degree difference, medical liquid atomizing
Mist droplet particle size is different.For specific medical fluid, partial size deviation will generate serious environmental pollution when the medical fluid requires atomizing particle size
With reduce pesticide utilization efficiency, and then influence disease pest and weed control efficiency.
When aircraft flight speed is fixed, the fluctuation of atomizer medical fluid input flow rate causes atomizer rotating cage rotation speed change, in turn
Influence atomizer fogging degree.
It is loaded with the aircraft of rotating cage atomizer, when aircraft spraying medicine completion is maked a return voyage or is operated without application, atomization
Device can dally, and atomizer critical mechanical device is not only easy to cause to strain and reduce its service life, and can turn because of atomizer
The dynamic flight resistance for increasing aircraft increases aircraft utilization cost to increase aircraft flight energy consumption.

It changes, utmostly reduces atomizer work energy consumption.
Pure wind driving and the switching of two kinds of spray patterns of wind-powered electricity generation combination drive are real by 12 setting speed value of rotating cage and rotating cage 12
The state of relationship and battery 22 between the tachometer value of border codetermines.
As actual speed value wx< setting speed value w, system are in wind-powered electricity generation combination drive mode, and driving motor is in power consumption
State, battery 22 are in discharge condition, power for driving motor, driving motor and wind drive atomizer to promote rotating cage jointly
12 revolving speed makes actual speed value wx=setting speed value w.
As actual speed value wx> setting speed value w, agricultural application are in pure pneumatic mode, at this time electric power storage with atomization system
Pond 22 is under charge mode, and blade 4 drives driving motor rotation to generate counter electromotive force U under the action of the wind1, at driving motor
In generating state, charge for battery 22.As actual voltage value UxWhen equal to 22 voltage rating U of battery, 4 angle of blade is controlled
Regulating mechanism 3 works, and changes 4 angle of attack of blade, reduces by 12 actual speed w of rotating cagexTo setting speed value w.
The above battery 22 has overload protection arrangement, disconnects automatically after charging complete.
One of embodiment according to the present invention, control module control driving motor by output pwm signal with certain
Rotational speed.It works in addition, control module controls the second driving unit by output pwm signal, to change 4 angle of attack of blade.
According to the agricultural application atomization system of above embodiments, control module is according to flow value q, actual speed value wxWith
The operating mode of relationship and battery 22 between setting speed value w adjusts 4 angle of attack of blade, realizes the maximization benefit of wind energy
With.Aircraft starting, control module control 4 angle adjusting mechanism 3 of blade and reset, and 4 angle of attack of blade is 45 degree at this time.Do not consider to store
In the case where battery 22, when atomizer medicinal liquid flow value q > 0, and wx> w, control module control 4 angle adjusting mechanism 3 of blade with
Reduce 4 angle of attack a of blade, makes wxReduce, while reducing by 4 windage of blade.On the contrary, wx< w, 4 angle adjusting mechanism 3 of blade increase blade
4 angle of attack a improve the utilization rate of wind energy, while wxIncrease.
As atomizer medicinal liquid flow value q=0, the voltage U of battery 22xLess than battery voltage rating U, 4 angle of blade
It is 45 degree that regulating mechanism 3, which adjusts 4 angle of attack of blade, is charged for battery 22；If Ux=U, 4 angle adjusting mechanism 3 of blade adjust paddle
4 angle of attack of leaf is 0 (along slurry), to reduce 4 bring windage of blade, improves the working efficiency of aircraft.
