[0029] Embodiment 1:

[0030] Please refer to Figures 1 to 4 , the present utility model provides a 220KV transmission line flaw detection device, which includes a device body 1 and a drone 2.

[0032] Please refer to Figure 3 , the hook 9 is provided with a second inclined portion 26, and the second inclined portion 26 forms a moving angle with the axial direction of the threaded rod 7, which is convenient for the hook 9 to be hung on the transmission line, so that the transmission line can enter the hook 9 along the second inclined portion 26.

[0033] The drone 2 is used to drive the device body 1 to the transmission line to be detected, and another drone 2 carries a pulse ray machine for taking images.

[0034] In this application, the drone 2 drives the device body, and the guide rod 12 is used for guiding, which is convenient for the moving mounting member to place the imaging plate 5 on the transmission line to be detected, so that the imaging plate 5 is located at the upper transmission line. After the upper transmission line is imaged by another drone 2 carrying a pulse ray machine, the lifting motor 10 is started. The lifting motor 10 drives the threaded rod 7 to rotate, the threaded rod 7 rotates to drive the slider 8 to move, and the slider 8 moves to drive the hook 9 to move, so that the hook 9 approaches the fixed rod 3, and the relative imaging plate 5 moves downward to the lower transmission line, thereby detecting the lower transmission line.

[0035] Embodiment 2:

[0036] Please refer to Figures 5 to 8 , the present utility model provides a 220KV transmission line flaw detection device, and a guide fixing member for stabilizing the imaging plate 5 is also assembled on the guide rod 12.

[0037] In this application, the device body 1 is driven by the drone 2, and the moving mounting member places the imaging plate 5 on the power transmission line to be detected, so that the imaging plate 5 is located at the power transmission line above. The guiding and fixing member guides during the process of placing the device body 1 on the power transmission line, enabling the moving mounting member to smoothly place the device body 1 on the power transmission line above. When the device body 1 is located on the power transmission line above, the guiding and fixing member can contact the power transmission line below, enabling the imaging plate 5 to be more stable during shooting, avoiding the shaking of the imaging plate 5 during shooting and affecting the shooting imaging effect. After completing the shooting imaging of the power transmission line above, the moving mounting member can move the imaging plate 5 to the power transmission line below, and the guiding and fixing member moves accordingly, thus completing the detection of the power transmission line below. The detection of the upper and lower two power transmission lines is carried out in one mounting, increasing the detection efficiency.

[0038] Please refer to Figures 6 to 8 As shown, the guiding and fixing member includes a passive gear 14 sleeved on the guiding rod 12. A spiral groove 13 is formed on the guiding rod 12. A sliding groove 15 is formed on one side of the passive gear 14. A driving ball 16 is fixedly connected to the passive gear 14. The driving ball 16 is located in the spiral groove 13. A sliding seat 17 is sleeved and slidably connected on the guiding rod 12. One end of the sliding seat 17 is fixedly connected with a stabilizing hook 18. A connecting rod 19 is fixedly connected to the sliding seat 17. A sliding block 20 is fixedly connected to the connecting rod 19. The sliding block 20 is located in the sliding groove 15. An installation cavity 21 is formed at the position of the sliding seat 17 close to the connecting rod 19. A rotating motor 22 is fixedly connected in the installation cavity 21. The output end of the rotating motor 22 is fixedly connected with a driving gear 23. The driving gear 23 meshes with the passive gear 14.

[0039] When the drone 2 drives the device body 1 to move towards the power transmission line above, the guiding rod 12 provided during the descending process plays a certain guiding role, enabling the hook 9 to be more easily hooked on the power transmission line above. When the hook 9 is hooked on the power transmission line above, the rotating motor 22 is started. The rotating motor 22 drives the driving gear 23 to rotate. The rotation of the driving gear 23 drives the passive gear 14 to rotate. The rotation of the passive gear 14 drives the driving ball 16 to move along the spiral groove 13, causing the passive gear 14 to move relative to the guiding rod 12. At the same time, the passive gear 14 drives the sliding seat 17 to move through the connecting rod 19. The movement of the sliding seat 17 drives the stabilizing hook 18 to move, enabling the stabilizing hook to contact the power transmission line below, enabling the imaging plate 5 to be stable between the power transmission lines, avoiding shaking caused by factors such as wind during operation, and making the shooting imaging effect clearer.

[0040] Please refer to Figure 6, on one side of the sliding seat 17 away from the stable hook 18, a connecting rod 24 is fixedly connected, and the other end of the connecting rod 24 is fixedly connected to another sliding seat 17. The connecting rod 19 connects the two sliding seats 17 so that the two sliding seats 17 can move synchronously.

[0041] Please refer to Figure 6 , on the stable hook 18, there is a first inclined portion 25. The first inclined portion 25 forms a certain angle with the axial direction of the guide rod 12 to guide the transmission line and stabilize the imaging plate 5. During the descent of the device body 1, the first inclined portion 25 can ensure that the lower transmission line can be fixed by the stable hook 18.

[0042] Please refer to Figure 7 and Figure 8 , the driving ball 16 is located in the spiral groove 13. The driven gear 14 moves axially along the guide rod 12 through the driving ball 16. During the movement of the driven gear 14, the sliding seat 17 can be driven to move through the connecting rod 19.
