[0040] When the above structure is in use, the driving motor drives one of the second driving shafts 902 to rotate, and under the action of the transmission belt 904, the two second driving shafts 902 drive the two driving gears 903 to rotate synchronously, so that the driving gear 903 can drive the conveying ring 3 to rotate stably.

[0041] Working principle: When in use, the invention uses the drone to land on the top of the parking platform 2 in the landing port 13. At this time, the stepper motor 416 is powered on and drives the first drive shaft 414 to rotate 90 degrees, so that the first drive shaft 414 drives the second drive platform 403 to rotate through the second connecting ring 503, and then the second drive platform 403 drives the first drive platform 402 to rotate;

[0042] Since the protrusion at the bottom of the first connecting ring 501 is movably connected to the groove at the top of the second connecting ring 503, when the second driving platform 403 rotates, the first driving platform 402 will be driven to rotate synchronously. In the initial state, the connecting line of the protrusion structure at the bottom of the first driving platform 402 is in a vertical state with the threaded rod 504.

[0043] When the first driving platform 402 and the second driving platform 403 rotate 90 degrees, the first driving platform 402 drives the first driving arm 404 to be hinged, and the second driving platform 403 drives the second hinged arm 408 to be hinged, and the first driving arm 404 drives the two first clamping seats 407 to move toward each other through the first movable block 405 and the first connecting column 406, and the second hinged arm 408 drives the two second clamping seats 411 to move toward each other through the second movable block 409 and the second connecting column 410, so that the two first clamping seats 407 and the two second clamping seats 411 are synchronously moved. Move toward each other and clamp the drone on the parking platform 2 in the center. When the first driving platform 402 and the second driving platform 403 rotate to 90 degrees, the line of the protruding structure at the bottom of the first driving platform 402 is parallel to the threaded rod 504, that is, the first connecting ring 501 and the second connecting ring 503 can move toward each other and disengage along the direction of the threaded rod 504, wherein the first guide groove 412 and the second guide groove 413 are provided to cooperate with the first connecting column 406 and the second connecting column 410 to guide the movement of the first clamping seat 407 and the second clamping seat 411;

[0044] When the two first clamping seats 407 and the two second clamping seats 411 move toward each other synchronously, the first movable block 405 drives the movable sleeve 506 to move on the surface of the threaded sleeve 505, so that the two first clamping seats 407 and the two second clamping seats 411 can normally clamp the drone in the center;

[0045] After that, the servo motor 511 is powered on and starts working, and the servo motor 511 drives the threaded rod 504 to rotate, and the threaded rod 504 is threadedly connected with the threaded sleeve 505. Since the driving head 502 cooperates with the third guide groove 507 to prevent the threaded sleeve 505 from rotating around the threaded rod 504, the threaded sleeve 505 and the threaded rod 504 can rotate relative to each other, and the threaded rod 504 drives the threaded sleeve 505 to move along the direction of the threaded rod 504. When the threaded sleeve 505 moves along the direction of the threaded rod 504 toward one end of the transmission position of the conveying ring 3, That is, when the threaded sleeve 505 moves toward the end away from the second maintenance station 11, the threaded sleeve 505 will drive the driving head 502 to move, wherein at this time, since the line of the protruding structure at the bottom of the first driving platform 402 is parallel to the threaded rod 504, the first connecting ring 501 and the second connecting ring 503 can move toward each other and disengage along the direction of the threaded rod 504, that is, the threaded sleeve 505 will drive the first driving platform 402, the first driving arm 404, the first movable block 405, the first connecting column 406 and the first clamping seat 407 to move through the driving head 502;

[0046] By setting the guide bar 509 and the guide fence 508, when the first driving platform 402 moves, the guide bar 509 will be parallel to the guide fence 508 and fit closely with the guide fence 508, that is, the guide fence 508 cooperates with the guide bar 509 to prevent the first driving platform 402 from rotating, that is, the two first driving arms 404 cannot rotate relative to the first driving platform 402, that is, the two first clamping seats 407 will always stably clamp the drone and move it until the drone moves to the conveying ring 3. At this time, the first connecting ring 501 moves to the position of the second guide frame 510. As the first The connecting ring 501 continues to move, which will make the first connecting ring 501 fit with the second guide frame 510, and through the protrusion at the bottom of the first connecting ring 501 cooperating with the guiding action of the second guide frame 510, the first driving platform 402 will rotate 90° in the opposite direction, that is, the two first driving arms 404 cooperate with the first movable block 405 and the first connecting column 406 to drive the two first clamping seats 407 to move away from each other, and place the drone on the conveying ring 3. After that, the conveying ring 3 rotates to drive the drone to the first maintenance station 10 for maintenance, and moves another drone between the two second retaining frames 7. At this time, it is necessary to When the UAV between the second retaining frames 7 is transported to the parking platform 2 for takeoff, the servo motor 511 drives the threaded rod 504 to rotate in the opposite direction, and the threaded rod 504 drives the driving head 502 to move toward one end of the parking platform 2 through the threaded sleeve 505. At the same time, the protrusion at the bottom of the first connecting ring 501 cooperates with the second guide frame 510 to make the first driving platform 402 rotate again, and make the two first clamping seats 407 approach each other to clamp the UAV. At the same time, the two first clamping seats 407 will drive the UAV to continue to move toward one end of the parking platform 2. When the first clamping seats 407 complete the clamping of the UAV, That is, after the first driving platform 402 rotates 90°, the guide bar 509 is parallel to the guide fence 508 again and fits tightly, so that during the transportation of the drone, the two first clamping seats 407 always stably clamp the drone until the protrusion at the bottom of the first connecting ring 501 moves into the groove at the top of the second connecting ring 503. At this time, the stepper motor 416 drives the first driving shaft 414 to rotate 90° in the opposite direction, so that the two first clamping seats 407 and the two second clamping seats 411 move away from each other synchronously and release the drone. At this time, the drone located on the top of the parking platform 2 can fly out from the landing port 13 to operate;

[0047] One of the second drive shafts 902 is driven to rotate by a driving motor, and under the action of a transmission belt 904, the two second drive shafts 902 rotate synchronously, and the two second drive shafts 902 drive the two drive gears 903 to rotate synchronously, wherein the two drive gears 903 rotate synchronously because there is a gap between two adjacent conveying rings 3, and the conveying rings 3 are driven to rotate synchronously by the two drive gears 903, so that the conveying rings 3 can rotate stably, and the conveying rings 3 can transport the UAVs that need to be repaired to the first maintenance station 10, the second maintenance station 11 and the third maintenance station 12 in turn, and perform various types of maintenance, so that multiple UAVs can perform different types of maintenance synchronously, which greatly reduces the maintenance time, wherein the first maintenance station 10, the second maintenance station 11 and the third maintenance station 12 can be maintenance stations such as image recognition maintenance and automatic cleaning as needed.
