When unmanned aerial vehicle 1 descends on platform 9, horizontal plate 4 is put on frame 10 top, and guide post 5 inserts inside frame 10.

The frame 10 is provided with a first push plate 11 inside two opposite end faces and a second push plate 12 inside the other two opposite end faces.

A first telescopic rod 1101 and a second telescopic rod 1201 are fixed below the platform 9, the end of the first telescopic rod 1101 is fixedly connected with the bottom of the first push plate 11, and the end of the second telescopic rod 1201 is fixedly connected with the bottom of the second push plate 12.

The width of the first push plate 11 is smaller than that of the end face of the frame 10 where the first push plate is located, and the width of the second push plate 12 is the same as that of the inner wall of the end face of the frame 10 where the second push plate is located.

First push pedal 11 and second push pedal 12 are all inlayed in frame 10 inner wall, and first push pedal 11 width is greater than the diameter 1 ~ 3mm of guide post 5.

The inner wall of the frame 10 is provided with a first slide 1001 arranged horizontally in a concave manner at positions on two sides of the first push plate 11, a partition plate is arranged between the first slide 1001 and the side wall of the first push plate 11, and two ends of the second push plate 12 are provided with slide blocks which are arranged inside the first slide 1001 in a sliding manner. The arrangement of the first slide 1001 and the inner slide thereof makes it impossible to clamp the guide post 5 when the two second push plates 12 move to the end.

The frame 10 is externally sleeved with a rotating ring 13, and the axis of the rotating ring 13 is superposed with the central line of the frame 10. An annular convex disc 1302 is convexly arranged at the bottom of the outer circumferential surface of the rotating ring 13, an annular pressing plate 14 is arranged above the convex disc 1302, and the outer circumferential surface of the annular pressing plate 14 is fixedly connected with the top surface of the platform 9. The rotary ring 19 is rotatably connected to the platform 9 via the annular pressure plate 14.

Two arc-shaped grooves 1301 are concavely arranged on the top surface of the rotating ring 13, and the radian of each arc-shaped groove 1301 is 120-170 degrees.

And a straightening rod 6 is vertically arranged below the two sides of the horizontal plate 4, and the height of the straightening rod 6 is smaller than that of the guide post 5.

The straightening rods 6 are cylindrical rods, the diameter of each straightening rod is smaller than the width of the arc-shaped groove 1301, and the two straightening rods 6 are respectively inserted into the arc-shaped grooves 1301.

The cover is equipped with the ring gear on the periphery of swivel 13 outside, and the ring gear is connected with gear 15 meshing, is fixed with first motor 1501 on the platform 9, and first motor 1501 output shaft drives gear 15 and rotates, first motor 1501 and unmanned aerial vehicle 1 control system wireless connection.

The unmanned aerial vehicle 1 flies above the platform 9 under the self-navigation effect, and the guide post 5 of the unmanned aerial vehicle is positioned in a method of opening the frame 10. Then unmanned aerial vehicle 1 descends, frame 10 top surface is equipped with the wireless distance sensor of practising with 1 control system of unmanned aerial vehicle or is equipped with infrared correlation photoelectric sensor at frame 10 inner wall top, a position for detecting unmanned aerial vehicle 1, guide post 5 stretches into the inside height of frame 10 promptly, when guide post 5 stretches into the inside distance of frame 10 and reaches the threshold value, when the distance that distance sensor detected promptly reaches threshold value or infrared correlation photoelectric sensor and detects the signal, unmanned aerial vehicle 1 stops descending. Then, the first push plate 11 and the second push plate 12 move to the center of the frame 10, and the second push plate 12 moves to the final position, i.e. the maximum stroke of the second telescopic rod 1201, and the indirect distance between the two first push plates 11 is larger than the diameter of the guide post 5.

Then unmanned aerial vehicle 1 continues to descend and sets for the distance, and the pole 6 of putting right this moment inserts inside arc groove 1301, and swivel 13 rotates 180, drives unmanned aerial vehicle 1 rotatory. A two-dimensional code or a bar code for detection is fixed at one end of the platform 9, which is positioned on the shelf 26, and if the reader 3 scans the content, the first push plate 11 continues to push to clamp the guide post 5; if the reader 3 does not scan the content, the swivel 13 is rotated again by 180 deg., at which point the reader 3 is rotated to the correct orientation.

In this embodiment, the platform 9 can charge the unmanned aerial vehicle 1. At least one sliding hole 9011 is provided with a brush 17 in a protruding manner on the inner wall, a conductor rail 1901 is recessed on the circumferential surface of a sliding rod 19 penetrating through the sliding hole 9011, the conductor rail 1901 is vertically arranged, and the brush 17 is electrically connected with the conductor rail 1901.

The brush 17 provides power for the first motor 1501, the first telescopic rod 1101 and the second telescopic rod 1201.

A bottom plate 16 is arranged below the bottom of the frame 10, the bottom plate 16 is fixedly connected with the platform 9 through a plurality of second connecting rods 1602, and charging devices matched with each other are arranged on the bottom plate 16 and the guide posts 5, and wireless charging or wired charging can be adopted.

When wired charging is adopted, a plug 1601 is convexly arranged above the bottom plate 16, and the plug 1601 is electrically connected with the brush 17. An insertion hole 501 is arranged below the guide post 5. The length of the plug 1601 is less than the depth of the arcuate slot 1301. Meanwhile, the bottom of the jack 501 is inverted funnel-shaped, so that the plug 1601 can be conveniently inserted.

When unmanned aerial vehicle 1 needs to charge, just with reader 3 earlier, then first push pedal 11 stops, does not produce the displacement, and unmanned aerial vehicle 1 continues to descend, and inside plug 1601 inserted jack 501, then first push pedal 11 produced the displacement, presss from both sides guide post 5 tightly.

A wire groove 2202 is concavely arranged below a second slide 2201 of the lower guide rail 22, a wire is arranged inside the wire groove 2202, one end of the wire is electrically connected with the conductive rail 1901, the other end of the wire is electrically connected with a power supply through a remote control switch, and the power supply adopts a power supply inside a warehouse.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
