[0002] With the rapid development of the power, transportation, and forestry sectors, the demand for inspection of infrastructure such as power transmission lines, railway tracks, and forest protection is increasing. Taking the power industry as an example, ultra-high voltage transmission lines are long and have complex environments. Traditional manual line inspections are inefficient (≤30 kilometers per person per day), rely on experience-based judgment, and pose safety risks associated with working at heights. Railway line inspections need to cover tracks, bridges, and facilities along the line, and manual inspections are insufficient to fully capture potential hazards. In forest protection, efficient monitoring methods are also needed to detect illegal logging, fire hazards, and other risks.

[0003] With its advantages of mobility, wide coverage, and accurate data collection, drones have become a core tool for modern power line inspection. By carrying camera devices, drone inspections can quickly collect data such as visible light and infrared thermal imaging, enabling intelligent identification of line defects (such as damaged insulators on power transmission lines, cracked railway tracks, and forest fires), which is a key link in "digital operation and maintenance".

[0004] Regarding the existing related technologies, the inventor believes that the following defects exist: In the existing technologies, the camera devices of some drones are fixed to the body or fixed by bolts. When it is necessary to disassemble, maintain or replace the camera device, the bolt fixing requires the use of tools to disassemble and install, which seriously reduces the efficiency of operation. Summary of the Invention

[0005] To address the technical problem that existing camera devices require tools for disassembly and assembly when disassembling, maintaining, or replacing them, which severely reduces operational efficiency, this utility model provides a camera mounting structure for unmanned aerial vehicle (UAV) power line inspection.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1: Please refer to Figures 1-4. This example shows a camera mounting structure for UAV line inspection, including a UAV body 1 and a camera device 2. A fixed plate 3 is fixedly connected to the bottom of the UAV body 1. Two upright plates 4 are fixedly connected to the bottom ends of the fixed plate 3. The camera device 2 is located between the two upright plates 4. A knob 8 is provided at one end of the fixed plate 3. A movable rod 9 is fixedly connected to the inner side of the knob 8. Two sliders 10 are fixedly connected to one end of the movable rod 9. A rotating shaft 11 is movably connected to one end of the movable rod 9. A gear 12 is fixedly connected to one end of the rotating shaft 11. Two racks 13 are meshed at both ends of the gear 12. A connecting plate 14 is fixedly connected to one end of the racks 13. A movable column 7 is fixedly connected to the bottom of the connecting plate 14. A prism block 6 is fixedly connected to one end of the movable column 7. Prism grooves 5 are machined on both sides of the camera device 2. The prism block 6 is plugged into the interior of the prism groove 5.

[0023] When it is necessary to disassemble and replace the camera device 2, first pull the knob 8 outward. The knob 8 will drive the movable rod 9 to move outward. Then rotate the knob 8. The knob 8 will drive the movable rod 9 to rotate. The movable rod 9 will drive the rotating shaft 11 to rotate through the slider 10. The rotating shaft 11 will drive the gear 12 to rotate. The rotation of the gear 12 will drive the two racks 13 to move. The racks 13 will drive the connecting plate 14 to move. The connecting plate 14 will drive the movable column 7 to move. The movable column 7 will drive the prism block 6 to move, so that the two prism blocks 6 are disengaged from the interior of the prism groove 5, thereby making it easy to remove the camera device 2 for replacement and maintenance. The operation is simple and convenient.

[0024] Furthermore, the interior of the vertical plate 4 is machined with a connecting groove 15, and the connecting plate 14 is movably connected inside the connecting groove 15. When the rack 13 drives the connecting plate 14 to move, the connecting plate 14 will move along the interior of the connecting groove 15, and the connecting groove 15 will limit the movement of the connecting plate 14.

[0025] Furthermore, a limiting groove 16 is machined inside the fixed plate 3, and the rack 13 is movably connected inside the limiting groove 16. When the rack 13 moves, the rack 13 will move along the inside of the limiting groove 16, and the limiting groove 16 will limit the movement of the rack 13.

[0026] Furthermore, the fixed plate 3 has a rotating groove 17 machined inside, and the rotating shaft 11 is rotatably connected inside the rotating groove 17. When the knob 8 is turned, the movable rod 9 will drive the rotating shaft 11 to rotate, and the rotating shaft 11 will rotate along the inside of the rotating groove 17.

[0027] Furthermore, the rotating shaft 11 has a movable groove 18 machined inside, and the movable rod 9 is movably connected inside the movable groove 18.

[0028] When the knob 8 drives the movable rod 9 to move outward, the movable rod 9 will move along the inside of the movable groove 18. At the same time, the movable rod 9 will pull the return spring 19 to extend. With the return spring 19 provided, when the knob 8 is released, the return spring 19 will return to its original position and retract. The return spring 19 will drive the movable rod 9 to move, thereby causing the knob 8 to move back to its original position.

[0029] Furthermore, two sliding grooves 20 are machined on the inner wall of one end of the movable groove 18. The slider 10 is movably connected inside the sliding groove 20. When the movable rod 9 moves along the inside of the movable groove 18, the movable rod 9 will drive the slider 10 to move along the inside of the sliding groove 20. The sliding groove 20 will limit the movement of the slider 10, so that when the knob 8 drives the movable rod 9 to rotate, the movable rod 9 will drive the rotating shaft 11 to rotate through the slider 10.

[0030] Furthermore, the inner side of the knob 8 is fixedly connected to the limiting post 21, and one end of the fixing plate 3 is machined with two limiting holes 22. The limiting post 21 is plugged into the inside of the limiting hole 22. When the reset spring 19 returns to its original position and retracts, the reset spring 19 will drive the movable rod 9 to move, and the knob 8 will drive the limiting post 21 to move, so that the limiting post 21 can be inserted into the inside of the limiting hole 22. The knob 8 is limited by setting the limiting post 21.

[0031] Working principle: By first pulling the knob 8 outward, the knob 8 will drive the movable rod 9 to move outward. Then, by rotating the knob 8, the movable rod 9 will rotate. The movable rod 9 will drive the rotating shaft 11 to rotate through the slider 10. The rotating shaft 11 will drive the gear 12 to rotate. The rotation of the gear 12 will drive the two racks 13 to move. The racks 13 will drive the connecting plate 14 to move. The connecting plate 14 will drive the movable column 7 to move. The movable column 7 will drive the prism block 6 to move, so that the two prism blocks 6 are disengaged from the interior of the prism groove 5, thus making it easy to remove the camera device 2 for replacement and maintenance. The operation is simple and convenient.
