Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with the accompanying drawings.It is emphasized that it is following
That illustrate to be merely exemplary rather than in order to limit scope of the present utility model and application thereof.
A kind of liquid level feedback formula anti-oscillating medicine-chest as shown in Figure 1, including casing 2 and case lid 4, wherein casing 2 is cylindrical shape
Structure, internal diameter is
As in figure 2 it is shown, level is provided with a diameter of in casing 2Thickness is the cylindrical baffle 10 of 20mm；
The lower section of baffle plate 10 is fluid reservoir.Being provided with backing plate 5 at the middle part of case lid 4, both are connected by screw, nut.Baffle plate 10 and pad
It is respectively equipped with spring deep gouge 8 on plate 5, by spring deep gouge 8, spring 7 is connected between baffle plate 10 and backing plate 5, it is ensured that spring 7
The central shaft of central shaft and casing 2 on same straight line.A diameter of 200mm of spring 7, rigidity is 0.5N/mm.Spring 7
All the time being in compressive state, when the full medicinal liquid of medicine-chest, spring 7 is in complete compressive state, and spring force is 75N；When medicine-chest is without medicine
During liquid, spring force is 20N.Spring 7 is mainly used in offsetting the part vibratory forces of medicinal liquid, it is to avoid inclination or the deflection of baffle plate 10 are existing
As；Backing plate 5 makes the active force of spring 7 can be distributed on case lid 4, prevents case lid 4 excessive and destroyed because of active force.
Surrounding at baffle plate 10 is coated with the rubber skidding 9 that thickness is 2.5mm so that baffle plate 10 is interference in casing 2
Coordinate.The outer surface of rubber skidding 9 and the inwall of casing 2 have certain fineness, it is ensured that baffle plate 10 can be close to casing 2
Inwall straight up and down slides, the inclination of anti-baffle plate 10 or deflection；Ensure the sealing to fluid reservoir simultaneously, prevent air from entering
Enter, be conducive to avoiding medicinal liquid to shake, and ensure the accuracy of liquid level feedback data.
Have through hole at the middle part of case lid 4 and backing plate 5, be used for distance measuring sensor 6 is installed, when in medicine-chest without medicinal liquid
Time, distance measuring sensor 6 is 120mm with the distance on baffle plate 10 top；When full medicinal liquid in medicine-chest, distance measuring sensor 6 and baffle plate 10
The distance on top is 10mm.Distance measuring sensor 6 uses infrared sensor, simple in construction, and light weight is inexpensive, good stability, measures essence
Degree height, for the real-time distance detecting itself and baffle plate 10, and feeds back to unmanned plane.
Owing to casing 2 uses uiform section structure, in baffle plate 10 straight up and down sliding process, be always ensured that fluid reservoir is close
Envelope.Under the effect of external atmospheric pressure and the compression stress of spring 7, and baffle plate 10 self has certain rigidity, can have
Effect avoids the concussion of medicinal liquid so that plant protection unmanned plane is during dispenser, along with the minimizing of medicinal liquid, the overall weight of anti-oscillating medicine-chest
The heart only can be longitudinally varying, without in cross directional variations, it is ensured that the accuracy of liquid level feedback data.Unmanned plane by with medicine-chest without
During medicinal liquid, distance measuring sensor 6 the data obtained compares, and draws liquid level, is monitored liquid level in real time by distance measuring sensor 6 high
Degree, and then draw and feed back medicinal liquid surplus and the real-time change of medicine-chest center of gravity, beneficially plant protection unmanned plane and carry out the benefit of flight attitude
Repay and fly control.
The most equidistantly it is provided with four in the outer, upside of casing 2 and the outer, downside of case lid 4 and connects flange 3, on casing 2
The connection flange about 3 connected on flange 3 and case lid 4 coordinate one by one, be connected with nut by screw.Casing 2 and case lid 4 it
Between be matched in clearance, it is ensured that the air between backing plate 5 with baffle plate 10 communicates with ambient atmosphere, for medicine-chest normally work offer protect
Barrier.
The bottom of described casing 2 is provided with two through holes, is respectively equipped with the screw boss 12 with through hole outside through hole, its
In screw boss 12 be connected with check valve 1, as water inlet by water pipe 14；Another screw boss 12 is by water pipe 14
It is connected with ball valve 13, as outlet.Check valve 1 is able to ensure that when injecting medicinal liquid in medicine-chest, medicinal liquid only import but no export.Ball valve 13
For controlling whether medicinal liquid flows out, when injecting medicinal liquid, ball valve 13 is closed；When medicine-chest works, ball valve 13 is opened.Pass through pressure cap
Water pipe 14 is pressed in screw boss 12 by 15, prevents liquid leakage.
Described connection flange 3 respectively with casing 2 and case lid 4 integrated injection molding；Described screw boss 12 and casing 2 one
Injection mo(u)lding.
Working of plastics the most preferentially selected by casing 2, case lid 4, backing plate 5, baffle plate 10, check valve 1, the material of ball valve 13, it is possible to subtract
Light medicine-chest weight.
The duty of liquid level feedback formula anti-oscillating medicine-chest is as shown in figs 2-4.
Medicine-chest without medicinal liquid as it is shown on figure 3, when in medicine-chest inject medicinal liquid time, now it is ensured that baffle plate 10 is positioned at casing 2 end
Portion, prevents air from entering, and closes ball valve 13, is injected not less than 750Pa pressure by check valve 1 by liquid-injection equipment in medicine-chest
Medicinal liquid, medicinal liquid pressure should be able to overcome the active force under the complete compressive state of spring 7.
When distance measuring sensor 6 detects its distance with baffle plate 7 for full medicinal liquid setting value, as shown in Figure 4, stop injecting
Medicinal liquid.Before unmanned plane carries out dispenser operation, water circuit system is put up, wherein the water inlet end of water pump and the ball valve 13 of outlet
It is connected, and opens ball valve 13, it is simple to pump working.
When medicine-chest works with unmanned plane, liquid level is constantly reducing, as in figure 2 it is shown, distance measuring sensor 6 detects itself and gear in real time
The distance of plate 10, and send the data to unmanned plane, unmanned plane judges the center of gravity of medicine-chest according to the liquid level of feedback, and carries out
Pose adjustment controls with flight；When unmanned plane detects that medicine-chest inner liquid medicine will be used up, switching off the pump, unmanned plane makes a return voyage again
Inject medicinal liquid.
It should be noted that, this utility model not designs for specific plant protection unmanned plane type, it has can
Transplantability is strong, the feature of wide adaptability, perfect by profile, and this utility model is applicable to any plant protection unmanned plane type.
