Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-3, a self-stabilizing agricultural unmanned aerial vehicle, includes organism 1, installs flight part 3 on the organism 1, and water tank 2 is installed to the lower extreme of organism 1, and a plurality of water inlets 21 have been seted up to equidistant on the circumference inner wall of water tank 2, and water inlet 21 sets up in the inside higher position department of water tank 2, and the communicating aqua storage tank 4 with water inlet 21 is seted up to the lateral wall of water tank 2.
It should be noted that, through setting up water inlet 21 in water tank 2 higher position department, on the one hand, can make water tank 2 can carry more water, and on the other hand, when the surge is less in water tank 2, the water fluctuation height is lower can not flow in the aqua storage tank 4, and the surge is less can not influence unmanned aerial vehicle's balance this moment, consequently need not to stabilize unmanned aerial vehicle.
Communicate through water course 5 between per two relative aqua storage tanks 4, and all sealing sliding connection has a sliding plug 7 in every aqua storage tank 4, and the lower extreme of sliding plug 7 passes through flexible gasbag 6 fixed connection at the interior bottom of aqua storage tank 4, communicates through pipe 8 between flexible gasbag 6 and the water tank 2 is inside.
The water inlet end of the guide pipe 8 penetrates through the side wall of the water tank 2 and extends to the inner bottom of the water tank 2, and part of the side wall of the guide pipe 8 is positioned above the liquid level in the water tank 2.
It should be noted that the natural inflow of the water in the water tank 2 into the conduit 8 can be prevented by making a part of the side wall of the conduit 8 higher than the liquid level in the water tank 2.
In this embodiment, when unmanned aerial vehicle turned or when the surge took place for the variable speed in the flight, the water in the water tank 2 will turn over and gush towards one side in the water tank 2 under the inertial action to in the water inlet 21 along this side flowed into the aqua storage tank 4. Using fig. 1 as an example, if rivers flow into left side aqua storage tank 4 after, will push down the sliding plug 7 in the left side aqua storage tank 4, and squeeze into the aqua storage tank 4 on right side with the air of sliding plug 7 below, force the sliding plug 7 in the right side aqua storage tank 4 to rise, will pull flexible gasbag 6 extension when the sliding plug 7 of right side rises, simultaneously with the water pumping partly to the flexible gasbag 6 on right side in the water tank 2, the gravity of the flexible gasbag 6 water of usable inflow right side comes the balanced surge water to the left impact force of organism 1, so can make unmanned aerial vehicle keep higher stability in variable speed or turn flight process.
So at the continuous variable speed of unmanned aerial vehicle or turn flight in-process, the sliding plug 7 of left and right sides constantly reciprocates, makes the water make a round trip to flow in aqua storage tank 4 and flexible gasbag 6, keeps the stable flight state of unmanned aerial vehicle. After the flight is finished, the water in the water storage tank 4 and the telescopic air bag 6 is poured out.
Example two:
referring to fig. 4-5, unlike the first embodiment, the sliding plug 7 is made of a magnetic material, the spiral coil 9 is embedded in the inner wall of the water storage tank 4, and the spiral coil 9 is disposed below the sliding plug 7.
The side wall of the water tank 2 is provided with a circular groove 10, the inner wall of the circumference of the circular groove 10 is fixedly connected with a plurality of electromagnets 13 at equal intervals, and each spiral coil 9 is coupled in a power supply circuit opposite to the electromagnets 13. The iron blocks 11 are connected in the circular groove 10 in a sliding mode, the iron blocks 11 are elastically connected to the inner wall of the circular groove 10 through a plurality of springs 12, and the springs 12 are distributed at equal intervals along the circumferential inner wall of the circular groove 10.
The second design embodiment is that the volume of the telescopic air bag 6 is limited, so that the pumped water body is less, and the situation of difficult balance can occur when the water body is overflowed too much.
In the initial state, the acting force of each spring 12 on the iron block 11 is the same, and the directions are opposite, so that the iron block 11 can be positioned at the center of the circular groove 10, and the balance state of the unmanned aerial vehicle can be kept.
Taking fig. 4 as an example, after the surge occurs, when the water that surges impacts the left inner wall of the water tank 2, the left sliding plug 7 is pushed to move downwards, at the moment, the sliding plug 7 gradually enters the spiral coil 9, and an induced current is generated to electrify the electromagnet 13 on the right side, and after the electromagnet 13 on the right side is electrified, the electromagnet 11 is attracted to a distance left, so that the impact force of the water on the left inner wall of the water tank 2 is balanced, and the flying stability of the unmanned aerial vehicle during speed change or turning can be further improved. In this process, the right spool 7 moves upward and is away from the spiral coil 9, so that the left electromagnet 13 is energized without changing the magnetic flux in the right spiral coil 9.
And the more violent the billowing, the water body can flow into the water storage tank 4 more quickly, the larger the impact force on the sliding plug 7 is, so that the movement speed of the sliding plug 7 can be accelerated, the size of the induced current and the magnetic force of the electromagnet 13 can be increased, the moving distance of the iron block 11 can be prolonged, and the impact force of the billowing water body can be balanced better.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
