There are certain potential safety hazards and regular inspections are required. The traditional inspection mode requires manual disassembly of the strain clamp, and then reassembly after inspection. The process is cumbersome, time-consuming and laborious. It is not only inefficient, but also cannot detect internal defects in time, and the inspection workload is extremely large.

Specific embodiments

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 7 , the present utility model provides a 500 kV transmission line X-ray live detection device, including a device body 1 and an unmanned aerial vehicle 2 for carrying a pulsed ray machine. The device body 1 includes a "U"-shaped bracket 3. A cross frame 4 is fixedly connected to the "U"-shaped bracket 3. The lower end of the cross frame 4 is symmetrically and fixedly connected with support rods 6 through telescopic rods 5. An imaging plate 8 is rotatably connected between the two support rods 6 through a rotating shaft 7. A rotating motor 9 is fixedly connected to one of the support rods 6, and the output end of the rotating motor 9 is fixedly connected to the rotating shaft 7. A lifting mechanism for telescoping the telescopic rod 5 is fixedly connected to the cross frame 4. Moving mechanisms for driving the imaging plate 8 to approach the transmission line are fixedly connected to both ends of the "U"-shaped bracket 3. Rollers 11 for placing on the transmission line are rotatably connected to both ends of the moving mechanism.

[0030] Most of the 500 kV transmission lines in China are set with four conductors. This device can perform live flaw detection operations through a single unmanned aerial vehicle (UAV) 2. First, the UAV 2 drives the device body 1 to the transmission line to be detected, and the rollers 11 are placed on the upper two transmission lines to be detected. After that, the UAV 2 returns and moves to the imaging plate 8 with the pulsed ray machine on board. The pulsed ray machine emits X-rays to take images of the transmission line to be detected, and the damage condition of the transmission line is detected. The imaging plate 8 is driven by the moving mechanism to approach the transmission line to be detected, so that the taken imaging photos can be clearer and it is easier to clearly understand the damage condition of the transmission line. When the detection of one transmission line above is completed, the telescopic rod is extended by the lifting mechanism, so that the support rod descends. The descent of the support rod drives the imaging plate 8 to descend to the lower transmission line, and then the lower transmission line is imaged. After completion, the telescopic rod is extended again by the lifting mechanism, and the imaging plate 8 is located below the lower two transmission lines. The rotation motor 9 is started to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the imaging plate 8 to rotate, so that the imaging plate 8 faces the transmission line on the other side. The same as the above process, the two transmission lines on the other side are detected. The detection of the four transmission lines is completed in one placement, and the detection task can be completed by a single UAV 2, greatly improving the detection efficiency.

[0031] Please refer to Figure 3 As shown in, the lifting mechanism includes fixed seats 11 symmetrically and fixedly connected to the cross frame 4. Each fixed seat 11 is fixedly connected with a winding motor 12. The output end of the winding motor 12 is fixedly connected with a winding wheel 13. The winding wheel 13 is connected to the bottom end of the telescopic rod 5 through a connecting line.

[0032] When it is necessary to detect the lower transmission line, the winding motor 12 is started. The winding motor 12 rotates to drive the winding wheel 13 to rotate, and the connecting line is unwound. Under the action of the gravity of the imaging plate 8 itself, the telescopic rod extends, and the imaging plate 8 moves downward to the lower transmission line, so as to facilitate the imaging of the lower transmission line. When it is necessary for the imaging plate 8 to be located above, the winding motor 12 is started. The winding motor 12 rotates to drive the winding wheel 13 to rotate, and the connecting line is wound up, so that the connecting line drives the telescopic rod to move upward, thereby driving the imaging plate 8 to move upward, so that the detection of the upper and lower two transmission lines on the same side can be completed in one placement.

[0033] Please refer to Figure 4 As shown in, the moving mechanism includes a sliding block 14 fixedly connected to the "U"-shaped bracket 3. A connecting rod 15 is slidably connected through the sliding block 14. A rack 16 is fixedly connected to the side of the connecting rod 15 away from the "U"-shaped bracket 3. A moving motor 17 is fixedly connected to one side of the sliding block 14. The output end of the moving motor 17 is fixedly connected with a gear 18. The gear 18 meshes with the rack 16.

[0034] After the device body 1 is placed on the transmission line, start the moving motor 17. The moving motor 17 drives the gear 18 to rotate. The rotation of the gear 18 causes the sliding block 14 to move through the rack 16 engaged therewith. The movement of the sliding block 14 drives the "U"-shaped bracket 3 to move. The movement of the "U"-shaped bracket 3 drives the cross frame 4 to move. The movement of the cross frame 4 drives the telescopic rod to move. The movement of the telescopic rod drives the support rod 6 to move. The movement of the support rod 6 drives the imaging plate 8 to approach the transmission line, thereby making the imaging of the pulse ray machine clearer and facilitating a clearer understanding of the damage condition of the transmission line.

[0035] Please refer to Figure 4 At the positions where the sliding block 14 contacts the connecting rod 15, roller shafts 19 are rotatably connected. The roller shafts 19 abut against the connecting rod 15. The sliding block 14 and the connecting rod 15 are in contact through the roller shafts 19, reducing the friction between the sliding block 14 and the connecting rod 15 and making the movement of the sliding block 14 smoother and more stable.

[0036] Please refer to Figure 2 Both ends of the connecting rod 15 are provided with the rollers 11 and the rollers 11 are rotatably connected. When the rollers 11 are placed on the transmission line, the connecting rod 15 can be supported, thereby supporting the entire device body 1.

[0037] Please refer to Figure 1 、 Figure 6 and Figure 7 The drone 2 is also used to drive the device body 1 to the transmission line to be detected. When the drone 2 carries the pulse ray machine, it takes pictures and detects the detection position. Using a single drone 2 can complete the entire flaw detection.

[0038] Please refer to Figure 5 The rotating motor 9 is used to drive the imaging plate 8 to face the other transmission line, and the flaw detection of four transmission lines can be completed in one placement process.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
