[0040] This application provides a cable inspection device, see [link to relevant documentation]. Figure 1 and Figure 2The system includes: a drone body 1, with at least two wings 2 respectively installed on the outer walls of both sides of the drone body 1, and a power component 3 installed at the end of the wing 2 away from the drone body 1, the power component 3 being able to drive the drone body 1 to take off; a detachable pod 4 is installed at the bottom of the drone body 1, the pod 4 having an opening at the bottom, a first electric cylinder 5 installed on the inner wall of the top of the pod 4, an angle adjustment component installed with the output end of the first electric cylinder 5 facing downward, and a detection component installed at the bottom of the angle adjustment component; the first electric cylinder 5 is used to drive the angle adjustment component and the detection component to move longitudinally along the pod 4, the angle adjustment component is used to adjust the angle of the detection component, and the detection component is used to detect the cable.

[0041] In this embodiment, the cable inspection device comprises a drone body 1, wings 2, a power unit 3, a pod 4, and a first electric cylinder 5, an angle adjustment component, and a detection component arranged within the pod 4. The power unit 3 is installed at the end of the wing 2 furthest from the drone body 1, and drives the drone body 1 to take off. The first electric cylinder 5 is installed on the inner wall at the top of the pod 4, the angle adjustment component is installed at the output end of the first electric cylinder 5, and the detection component is installed at the bottom end of the angle adjustment component. During inspection, the first electric cylinder 5 pushes the angle adjustment component and the detection component out of the pod 4, and after inspection, the first electric cylinder 5 retracts the angle adjustment component and the detection component into the pod 4. The cable is inspected by the detection component, the angle of the detection component is adjusted by the adjustment component, and the angle adjustment component and the detection component are driven by the first electric cylinder 5 to move longitudinally within the pod 4 to complete the inspection of the cable.

[0042] Compared to existing cable inspection devices, this cable inspection device uses a drone equipped with a detection component to inspect cables. The angle of the detection component is adjusted by an angle adjustment component, and relevant data on the outer diameter of the cable are obtained through the detection component. This enables all-round inspection of cable components from the air, with a focus on inspecting defects. The inspection range is larger, not limited by terrain, with high inspection efficiency and good inspection effect. Moreover, the placement and retrieval process is convenient and easy to use.

[0043] In one embodiment of this application, see [link to application]. Figure 5 The main body 1 of the drone is equipped with a controller 6, which is electrically connected to the power component 3, the first electric cylinder 5, the angle adjustment component, and the detection component. This enables intelligent control of the cable inspection device, facilitating cable inspection and detection.

[0044] In one embodiment of this application, the wing 2 is a retractable wing, and the wing 2 is electrically connected to the controller 6. Thus, the size of the wing 2 can be adjusted according to the environment in which the drone body 1 is located, facilitating the adjustment of the flight attitude of the drone body 1.

[0045] In one example, see Figure 1Two wings 2 are respectively provided on the outer walls of both sides of the main body 1 of the drone, and the wings 2 are tilted. At the same time, the two wings 2 on the same side are symmetrically arranged.

[0046] In one embodiment of this application, see [link to application]. Figure 1 and Figure 2 The power assembly 3 includes a first motor 301 and a propeller 302. The first motor 301 is located at the end of the wing 2 away from the main body of the drone 1, with its output end facing upwards. The propeller 302 is located at the output end of the first motor 301. Thus, the first motor 301 drives the propeller 302 to rotate, providing lift to the main body of the drone 1, thereby enabling the drone 1 to take off and control its flight attitude.

[0047] In one embodiment of this application, see [link to application]. Figure 2 and Figure 3 The angle adjustment assembly includes: a transmission box 7, located at the output end of the first electric cylinder 5; a second electric cylinder 8, located on the inner wall of one side of the transmission box 7; a rack 9, connected to the output end of the second electric cylinder 8; and a rotating rod 10, rotatably mounted on the inner wall at the bottom of the transmission box 7. The top of the rotating rod 10 is equipped with a gear 11 that meshes with the rack 9, and the bottom of the rotating rod 10 extends out of the transmission box 7 and connects to the detection assembly. This allows for adjustment of the circumferential detection angle of the detection assembly, facilitating the detection assembly's inspection of cables.

[0048] Understandably, when it is necessary to adjust the circumferential angle of the detection component, the second electric cylinder 8 is activated, which drives the rack 9 to move. Through the rack and pinion transmission between the rack 9 and the gear 11, the gear 11 is driven to rotate, which in turn drives the rotating rod 10 to rotate, thereby causing the detection component to rotate around the rotating rod 10 and changing the circumferential detection angle of the detection component.

[0049] In one embodiment of this application, see [link to application]. Figure 3 The inner walls on both sides of the gondola 4 are respectively provided with axially extending grooves 401, and sliders 402 are slidably disposed in the grooves 401. The sliders 402 are disposed on the outer wall of the transmission box 7. The first electric cylinder 5 can drive the transmission box 7 to move longitudinally along the grooves 401. In this way, the direction of movement of the transmission box 7 can be restricted, so that the angle adjustment component and the detection component can only move longitudinally in the gondola 4, thereby improving the smoothness of movement of the angle adjustment component and the detection component and improving the detection accuracy of the detection component.

[0050] In one embodiment of this application, see [link to application]. Figures 2 to 4The detection assembly includes: a U-shaped plate 12, located at the bottom of the rotating rod 10, with its opening facing downwards; a second motor 13, located on one inner wall of the U-shaped plate 12, with its output end connected to one end of a rotating shaft 14, and the other end of the rotating shaft 14 rotatably connected to the other inner wall of the U-shaped plate 12; and a mounting box 15, located inside the U-shaped plate 12, with the rotating shaft 14 passing through and fixedly connected to the mounting box 15; an opening is provided on one side wall of the mounting box 15, within which a glass plate 16 is placed; a camera 17 and a distance sensor 18 are mounted on the inner wall of one side of the mounting box 15, both facing the glass plate 16. This allows for adjustment of the longitudinal detection angle of the camera 17 and the distance sensor 18, facilitating the detection of cables by the camera 17 and the distance sensor 18.

[0051] Optionally, the camera 17 is used to capture images of the cable's appearance, thereby obtaining the cable's outer diameter data and determining whether there is any damage or protrusion on the cable surface.

[0052] Optionally, the ranging sensor 18 is used to detect the actual size of cable surface damage or protrusions based on the outer diameter data of the cable obtained by the camera 17, so as to facilitate repair by the staff.

[0053] It should be noted that after the camera 17 and the ranging sensor 18 acquire images and actual dimensions of the cable surface damage or protrusion, the damaged or protruding parts can be marked and warned, and similar parts can be given priority in subsequent inspections.

[0054] Understandably, when it is necessary to adjust the longitudinal angle of the camera 17 and the distance sensor 18, the second motor 13 is started, which drives the rotating shaft 14 to rotate. This causes the mounting box 15 to rotate around the rotating shaft 14 within the U-shaped plate 12, thereby causing the camera 17 and the distance sensor 18 inside the mounting box 15 to rotate around the rotating shaft 14, changing the longitudinal detection angle of the camera 17 and the distance sensor 18. During the rotation, the camera 17 and the distance sensor 18 always face the glass plate 16, which facilitates the camera 17 and the distance sensor 18 in detecting the cable. The glass plate 16 protects the camera 17 and the distance sensor 18, preventing damage to them and improving the accuracy of the detection.

[0055] Understandably, by adjusting the circumferential detection angle of the camera 17 and the distance sensor 18 through the angle adjustment component, and by adjusting the longitudinal detection angle of the camera 17 and the distance sensor 18 through the second motor 13, the detection angle of the camera 17 and the distance sensor 18 can be adjusted in real time during cable inspection through the cooperation of the angle adjustment component and the second motor 13, so as to achieve all-round detection of the cable and improve the detection effect of the cable.

[0056] In one embodiment of this application, see [link to application]. Figure 3 A rubber sealing ring 19 is provided at the bottom of the mounting box 15. In this way, after the angle adjustment component and the detection component enter the pod 4, the bottom opening of the pod 4 can be sealed to prevent foreign objects from entering the pod 4 and damaging the angle adjustment component and the detection component.

[0057] In one embodiment of this application, see [link to application]. Figure 5 The main body of the drone 1 also includes a data processing module 20, a data storage module 21, a data transmission module 22, and a wireless communication module 23. The controller 6 is electrically connected to the data processing module 20, the data storage module 21, the data transmission module 22, and the wireless communication module 23. This allows staff to quickly and accurately obtain the detection results from the camera 17 and the ranging sensor 18, facilitating timely repair of any damage to the cable.

[0058] Optionally, the data processing module 20 is used to process the data detected by the camera 17 and the ranging sensor 18.

[0059] Optionally, the data storage module 21 is used to store the data processed by the data processing module 20.

[0060] Optionally, the data transmission module 22 is used to transmit the detection data stored in the data storage module 21 to the console.

[0061] Optionally, the wireless communication module 23 is used for command transmission between the console and the main body of the drone 1.

[0062] In one embodiment of this application, see [link to application]. Figure 2 The main body of the drone 1 has two landing gears 24 symmetrically arranged at its bottom, and the pod 4 is located between the two landing gears 24. This allows for convenient take-off and landing of the main body of the drone 1, making the drone 1 easy to use.
