It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a safety detection device for high-voltage transmission lines, including a scissor lift 1. The top of the scissor lift 1 is installed with a top plate 2, and the top plate 2 is firmly connected to the top of the lift by welding or bolting to ensure that it will not shake during the lifting process. On the top surface of the top plate 2, a fixed plate 3 is fixedly installed, and the fixing method can be bolt connection or welding to enhance the structural stability. On the side surface of the fixed plate 3, a bent frame 4 is fixedly installed. The bent frame 4 is designed as a circular structure, which allows the camera 12 to rotate at a large angle, thus realizing the comprehensive detection of the transmission line. On the surface of the bent frame 4, a central groove 5 and a sliding groove 6 are provided. The inner wall of the sliding groove 6 is connected with a sliding rod 7 by a sliding connection method, and the sliding rod 7 can slide freely in the sliding groove 6. This design greatly improves the flexibility of the detection device. The top of the sliding rod 7 is fixedly installed with a short plate 8, and on the top surface of the short plate 8, a motor 9 is fixed by bolts. The output end of the motor 9 is installed with a roller 10. The roller 10 is in contact with one side of the inner wall of the central groove 5. This design enables the roller 10 to roll stably in the central groove 5, and then drives the short plate 8 to move along the inner side of the bent frame 4. The roller 10 is not in contact with the other side of the inner wall of the central groove 5. This design is to avoid excessive friction when the roller 10 moves.

[0025] Please refer to Figures 1-4 , on the top surface of the short plate 8, an installation frame 11 is also fixedly installed. The material of the installation frame 11 is PP plastic, which has high strength and corrosion resistance and can ensure the stable installation of the camera 12 and the supplementary light 13. The installation frame 11 is designed as a "U" - shaped structure, which not only facilitates the installation of the camera 12 and the supplementary light 13, but also can protect these devices from the damage of the external environment to a certain extent. On the top surface of the installation frame 11, the camera 12 and the supplementary light 13 are fixedly installed by bolts. The camera 12 is used to collect the images of the transmission line, and the supplementary light 13 provides necessary illumination to ensure that the camera 12 can work normally under various light conditions.

[0026] Embodiment 2

[0027] Please refer to Figures 3-4, a maintenance mechanism is provided on the surface of the mounting bracket 11. The maintenance mechanism includes a side groove 14, which is directly opened on the surface of the mounting bracket 11. Its internal structure is designed to be smooth and wear-resistant to ensure the smooth operation of the sliding components. A short rod 15 is slidably connected to the inner wall of the side groove 14. The short rod 15 is made of cemented carbide material and can withstand long-term sliding friction without being easily worn. One end of the short rod 15 is fixedly installed with a vertical block 16. The vertical block 16 and the short rod 15 are connected by welding or screw fastening to ensure the structural stability. The top end of the vertical block 16 is fixedly installed with a horizontal plate 17. The material of the horizontal plate 17 is a carbon fiber composite material. This material is both lightweight and has high strength, making it very suitable for the maintenance mechanism that needs to be frequently moved and operated. A push handle 19 is fixedly installed on the top surface of the horizontal plate 17. The material of the push handle 19 is PP plastic. This material is strong and durable and can withstand the pulling force during frequent manual operations without being easily broken. At the same time, PP plastic also has a certain anti-slip performance, enabling the operator to have a better hand feeling when pushing the push handle 19, improving the convenience and safety of the operation. A brush 18 is fixedly installed on the bottom surface of the horizontal plate 17. The brush 18 is made of nylon material. This material is soft and wear-resistant and can effectively protect the surface to be cleaned from damage during the cleaning process. The brush 18 is evenly distributed on the bottom surface of the horizontal plate 17 to ensure the uniformity and efficiency of the cleaning.

[0028] Working principle: The scissor lift 1 raises the bending frame 4 until the bending frame 4 is located on the surface of the line. Then, it can be illuminated by the supplementary light 13, and the image can be collected by the camera 12 to determine whether the surface of the transmission line is damaged. At the same time, the motor 9 can drive the roller 10 to rotate. At this time, the roller 10 can move in the central groove 5, which can drive the short board 8 to move. The short board 8 can slide through the slide rod 7 and the chute 6, so as to move along the inner side of the bending frame 4. Since the bending frame 4 is a circular structure, multi-angle imaging of the transmission line can be performed at this time, so as to more effectively detect the transmission line. The utility model drives the roller 10 to rotate through the motor 9, combines the movement of the roller 10 in the central groove 5 and the sliding mechanism of the short board 8, and can perform multi-angle imaging along the inner side of the bending frame 4. Since the bending frame 4 is designed as a circular structure, this design enables the camera 12 to perform a large-angle comprehensive detection of the transmission line, so as to more accurately capture any damage or abnormality on the surface of the line. And because the short board 8 can slide through the slide rod 7 and the chute 6, the flexibility of the detection device is increased, enabling it to adapt to transmission lines of different diameters and shapes, thus expanding the application range of the detection device. The staff can push the push handle 19, and the push handle 19 can then drive the cross board 17 to move. The cross board 17 can then drive the vertical block 16 to move. The vertical block 16 can then drive the short rod 15 to slide in the side groove 14. At this time, the cross board 17 can be moved. The cross board 17 can then drive the brush 18 to rub the camera 12 and the supplementary light 13, and the cleaning operation can be performed at this time. The utility model moves the brush 18 to clean the camera 12 and the supplementary light 13 by simply pushing the push handle 19, making the cleaning operation simple and fast, greatly improving the cleaning efficiency. It not only simplifies the cleaning steps, but also makes the daily maintenance of the equipment easier. The staff can easily complete the cleaning work without disassembling the equipment or using complex tools.
