Description
Technical field
Unmanned air vehicle technique field is the utility model is related to, especially a kind of fixed-wing VTOL formula unmanned plane, specifically relates to
And it is a kind of can be with the propeller of stopping a train at a target point.
Background technology
UAV is to utilize radio robot and the programme-control provided for oneself referred to as " unmanned plane " (" UAV ")
The not manned vehicle that device manipulates.Unmanned plane is actually the general designation of unmanned vehicle, can be with from technical standpoint definition
It is divided into：Unmanned fixed wing aircraft, unmanned VTOL aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aerocraft, nothing
People's parasol etc..Compared with manned aircraft, it have small, low cost, it is easy to use, to operational environment require low, battlefield
The advantages that survival ability is stronger.Since UAV has great significance Future Air Combat, each main military state of the world
Family is all stepping up the development work of progress UAV.
In recent years, due to the influence for the advantage such as multi-rotor unmanned aerial vehicle limits from place, can hover, cost is low, its model
And quantity rapidly increases, but the factors such as power, aerodynamic arrangement are limited by, more rotors are in voyage, speed, flight time etc.
It is difficult to meet more and more harsh user demand.Fixed-wing unmanned plane cruising time is long, speed is high, but needs takeoff runway,
Its availability is constrained significantly.
The generally applicable aerophotogrammetry of fixed-wing unmanned plane continuation of the journey, the monitoring of side room, military surveillance and alert fire fighting monitoring,
The industries such as power-line patrolling, urban planning, territory investigation, mineral exploration and exploitation, emergency disaster relief, forest fire protection, ecological monitoring, flood-control and drought relief
And the special trade of other unmanned plane operations.
Also there are following defect for current fixed-wing unmanned plane：
1st, stopping cannot be pinpointed, it is inconsistent with aircraft cruise direction, add the resistance during cruise；
2nd, propeller is easily swung during cruise, and security has much room for improvement.
Utility model content
The purpose of this utility model, which is to provide one kind, allows propeller to pinpoint stopping, consistent with aircraft cruise direction, subtracts
Resistance during few cruise, can also avoid propeller from being swung during cruise, improve can determining for security
The propeller of point parking.
In order to solve the problems existing in background technology, the utility model is to use following technical scheme：One kind can determine
The propeller of point parking, it includes propeller, motor, magnet one, power arm and magnet two, wherein, the propeller passes through spiral shell
Nail is fixedly mounted in the shaft of motor；The two panels blade of the propeller is mounted on magnet close to one end of machine shaft
One；The motor is fixed by screws on power arm；Magnet two is installed above the power arm, and the magnet two with
The position of magnet one is corresponding.
As further improvement of the utility model；The S of the magnet one is extremely downward.
As further improvement of the utility model；The N of the magnet two is extremely upward.
After adopting the above technical scheme, the utility model has the advantages that：
1st, simple in structure, material is seen everywhere in life, without complicated operation；
2nd, realize the stopping a train at a target point of propeller, reduce the resistance during unmanned plane cruise, realize energy-efficient；
3rd, prevent the swing of propeller in flight course, lift the security of unmanned plane during flying.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the structure diagram of embodiment provided by the utility model；
Reference numeral：
1-propeller；2-motor；3-magnet one；4-power arm；5-magnet two.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, is further elaborated the utility model.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, present embodiment uses following technical scheme：It is a kind of can be with the propeller of stopping a train at a target point, it
Comprising propeller 1, motor 2, magnet 1, power arm 4 and magnet 25, wherein, the propeller 1 is fixedly mounted on by screw
In the shaft of motor 2；The two panels blade of the propeller 1 is mounted on magnet 1 close to one end of 2 shaft of motor；The electricity
Machine 2 is fixed by screws on power arm 4；The top of the power arm 4 is provided with magnet 25, and the magnet 25 and magnet
One 3 position is corresponding；The S of the magnet 1 is extremely downward；The N of the magnet 25 is extremely upward.
The principle of the utility model is：
One piece of magnet 1, the S of magnet 1 are respectively installed close to that one end of 2 shaft of motor in the two panels blade of propeller 1
Downward, the corresponding top of power arm 4 installation magnet 25, the N poles of magnet 25 upward, motor 2 are fixed by screws in dynamic for pole
On the arm of force 4, propeller 1 and the shaft of motor 2 are connected by screw.
When motor 2 starts, it is only necessary to overcome attraction a little between magnet 25 and magnet 1, just can normally open
It is dynamic；
When motor 2 runs well, the 1 fly-cutting magnetic line of force of propeller, the magnetic force between magnet 25 and magnet 1, to electricity
The influence of machine 2 and propeller 1 can be neglected；
When motor 2 stops, propeller 1 is during gradually rotating speed is reduced, the attraction between magnet 25 and magnet 1
Power can make the parking direction of propeller 1 consistent with cruise direction, reduce during cruise propeller 1 because posture is indefinite to nothing
Resistance caused by man-machine, lifts the work efficiency of oil machine.
The utility model realizes the stopping a train at a target point of propeller with the attraction between magnet；All set at propeller both ends
With size magnet, it is ensured that dynamic balancing of the propeller in rotary course.
