[0021] Example 1, as Figures 1-4 As shown, the UAV wire-laying device proposed in this embodiment includes a UAV body 1 and an installation mechanism; a housing 2 is provided on the UAV body 1, and two mounting shafts 7 with coincident axes and two countersunk holes are rotatably connected to the housing 2, and a wire roller 8 is provided on the mounting shaft 7.

[0022] The mounting mechanism includes a fixed plate 4 mounted on the drone body 1, a connecting plate 3 rotatably connected to the fixed plate 4, multiple first bolts 5 penetrating the connecting plate 3 and abutting against each other, and a fixing component mounted on the mounting shaft 7; both the drone body 1 and the housing 2 are provided with multiple threaded grooves for the first bolts 5 to be screwed into; the fixing component includes an insert 9 mounted on the online roller 8 and two second bolts 11 threaded into the inside of the countersunk hole and penetrating the insert 9; the mounting shaft 7 is provided with a positioning groove 10 that is compatible with the insert 9.

[0023] The housing 2 is provided with four symmetrically distributed positioning blocks 6, and the drone body 1 is provided with a sliding groove for the positioning blocks 6 to slide.

[0024] In this embodiment, when it is necessary to replace the wire roller 8 inside the housing 2, first unscrew the first bolt 5 on the connecting plate 3 from the threaded groove on the drone body 1 and the housing 2, then slide the positioning block 6 out of the slide groove to remove the housing 2 from the drone body 1. Then unscrew the second bolt 11 from the countersunk hole of the mounting shaft 7 to remove the insert block 9 of the wire roller 8 from the positioning groove 10 of the mounting shaft 7, thus completing the disassembly operation of the wire roller 8. A new wire roller 8 can then be installed. The operation is simple and convenient, avoiding the need to disassemble all transmission components and the splicing structure of the housing 2 when replacing the wire roller 8. This reduces the difficulty of replacing the wire roller 8, optimizes the convenience of using the device, and has good practicality.

[0025] Example 2, as Figure 2 and Figure 4 As shown, this embodiment of the unmanned aerial vehicle (UAV) wire-laying device differs from Embodiment 1 in that, in this embodiment, the housing 2 contains a drive assembly. The drive assembly includes a motor 13 housed inside the housing 2, a worm gear 14 driven by the motor 13, and a worm wheel 15 coaxially mounted on the mounting shaft 7. The worm wheel 15 and the worm gear 14 are meshed together. A fixed seat 12 is provided inside the housing 2, and the motor 13 is mounted on the fixed seat 12. A connecting shaft 16 is coaxially mounted on the worm gear 14. The fixed seat 12 not only secures the motor 13 but also provides some protection. When wire laying is required, the motor 13 is started to drive the worm gear 14 to rotate, causing the worm gear 14 and the worm wheel 15 to mesh and transmit power. The worm wheel 15 then drives the mounting shaft 7 to rotate, which in turn drives the wire roller 8 to rotate, thus performing the wire laying operation.

[0026] Example 3, as Figure 4 As shown in the figure, the UAV wire-laying device proposed in this embodiment, compared with the second embodiment, has a guide assembly inside the housing 2. The guide assembly includes two symmetrically distributed mounting blocks 17, a first rotating rod 18 and a second rotating rod 25 respectively rotatably connected to the two mounting blocks 17, a guide wheel 22 coaxially arranged on the first rotating rod 18 and the second rotating rod 25, a first bevel gear 19 coaxially arranged on the first rotating rod 18, a second bevel gear 20 coaxially arranged on the connecting shaft 16, and a first cylindrical gear 23 and a second cylindrical gear 24 coaxially arranged on the first rotating rod 18 and the second rotating rod 25 respectively. The first bevel gear 19 and the second bevel gear 20 are meshed together, and the first cylindrical gear 23 and the second cylindrical gear 24 are meshed together. When laying the wire, the wire will pass between the two guide wheels 22, which plays a guiding role for the wire.

[0027] The housing 2 has a horizontal plate 26 inside, and the mounting block 17 is mounted on the horizontal plate 26. The horizontal plate 26 is used to fix the mounting block 17 located above. The housing 2 has multiple support frames 21 inside. The worm gear 14 and the connecting shaft 16 are rotatably connected to the support frame 21. The support frame 21 is used to support the rotation of the worm gear 14 and the connecting shaft 16 to ensure the stability of the transmission structure.

[0028] In this embodiment, when the drive roller 8 rotates to feed the wire, the worm gear 14 drives the connecting shaft 16 to rotate. The connecting shaft 16 drives the second bevel gear 20 and the first bevel gear 19 to mesh and transmit power. In turn, the first bevel gear 19 drives the first rotating rod 18 to rotate. The first rotating rod 18 drives the first cylindrical gear 23 and the second cylindrical gear 24 to mesh and transmit power. This causes the upper and lower guide wheels 22 to rotate relative to each other, so that the wire passing through the two guide wheels 22 is transported under the action of friction, while avoiding knotting and tangling during the wire feeding process.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
