People's parasol etc..Compared with manned aircraft, it has small volume, low cost, easy to use, low to operational environment requirement, battlefield
The advantages that survival ability is stronger.Because UAV has great significance to Future Air Combat, each main military state of the world
Family is all stepping up the development work of progress UAV.
In recent years, because multi-rotor unmanned aerial vehicle do not limited by place, can hover, low cost and other advantages are influenceed, 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's request.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.
Following defect also be present in 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.
The content of the invention
It is an object of the invention to provide one kind to allow propeller to pinpoint stopping, and consistent with aircraft cruise direction, reduction is patrolled
Resistance during boat, propeller can also be avoided to be swung during cruise, improve can pinpointing for security and stop
The propeller of car.
In order to solve the problems existing in background technology, the present invention is to use following technical scheme：One kind, which can pinpoint, stops
The propeller of car, it includes propeller, motor, magnet one, power arm and magnet two, wherein, the propeller is consolidated by screw
Dingan County is in the rotating shaft of motor；The two panels blade of the propeller is mounted on magnet one close to one end of machine shaft；Institute
Motor is stated to be fixed by screws on power arm；Magnet two, and the magnet two and magnet are installed above the power arm
One position is corresponding.
As a further improvement on the present invention；The S of described magnet one is extremely downward.
As a further improvement on the present invention；The N of described magnet two is extremely upward.
After adopting the above technical scheme, the invention has the advantages that：
1st, simple in construction, material is seen everywhere in life, the operation without complexity；
2nd, the stopping a train at a target point of propeller is realized, the resistance during unmanned plane cruise is reduced, realizes energy-efficient；
3rd, the swing of propeller in flight course is prevented, lifts the security of unmanned plane during flying.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of embodiment provided by the present invention；
Reference：
1-propeller；2-motor；3-magnet one；4-power arm；5-magnet two.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with accompanying drawing and specific implementation
Mode, the present invention will be described in further detail.It should be appreciated that embodiment described herein is only explaining this
Invention, is not intended to limit the present invention.
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 rotating shaft of motor 2；The two panels blade of the propeller 1 is mounted on magnet 1 close to one end of the rotating shaft of motor 2；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 described magnet 1 is extremely downward；The N of described magnet 25 is extremely upward.
The present invention principle be：
One piece of magnet 1, the S of magnet 1 are respectively installed close to that one end of the rotating shaft of motor 2 in the two panels blade of propeller 1
Down, 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, the rotating shaft of propeller 1 and motor 2 is 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 fly-cutting magnetic line of force of propeller 1, 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, lift the operating efficiency of oil machine.
The present invention realizes the stopping a train at a target point of propeller with the attraction between magnet；At propeller both ends, same chi is all set
Very little big small magnet, it is ensured that dynamic balancing of the propeller in rotary course.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
