DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions of the present application will be further described in detail below in conjunction with the specific embodiments.

A V-shaped notch is provided on the clamping plate 25. The contact between the rubber anti-slip pad 26 and the ground can increase the friction, thereby improving the stability of the placement of the support base 1 and avoiding accidental sliding. And the V-shaped notch on the clamping plate 25 can perform multi-point restriction on the arrester, thereby preventing the arrester from moving and shifting.

[0017] A protective cover 3 is fixedly connected to one side of the guiding column 2 of the support base 1. A working motor 4 is fixedly installed above the guiding column 2. The output shaft of the working motor 4 is connected to a lead screw 5. The lead screw 5 is rotationally connected to the protective cover 3 through a bearing. A threaded sleeve 9 is in threaded cooperation with the lead screw 5. The movable block 8 slides in the protective cover 3. The protective cover 3 protects the lead screw 5, reducing the direct contact between the lead screw 5 and the outside world. And the sliding of the sliding sleeve 6 on the guiding column 2 enables the guiding column 2 to guide and restrict the movement of the movable block 8, so that the movable block 8 can move smoothly and avoid rotation and deflection.

The movable end of the electric push rod 11 is fixedly connected to a movable frame 12. The movable frame 12 is integrally designed in a U shape. The guiding rod 10 is slidably matched with the movable frame 12. Connecting springs 27 are sleeved at both ends of the guiding rod 10. One end of the connecting spring 27 is connected to the inner wall of the fixed platform 7, and the other end of the connecting spring 27 is connected to the movable frame 12. When the electric push rod 11 pulls the movable frame 12, the movable frame 12 will slide along the guiding rod 10, thereby restricting the movement of the movable frame 12 through the guiding rod 10 and avoiding deflection during movement. And when the movable frame 12 moves, it will compress or stretch the connecting springs 27 at both ends of the guiding rod 10, thereby playing a buffering role and making the movement smoother and more stable.

[0019] One side of the movable frame 12 is fixedly connected to a fixed rack 13. A connecting rod 14 is rotationally connected to the fixed platform 7 through a bearing. A gear 15 is fixedly connected to the connecting rod 14. One end of the connecting rod 14 is fixedly connected to a deflecting plate 16.

A guiding groove 28 is provided on the deflecting plate 16. Through the meshing of the gear 15 and the fixed rack 13, the fixed rack 13 can drive the connecting rod 14 to rotate, thereby adjusting the deflecting plate 16 to change the angle of the arrester, so as to facilitate the staff to observe the arrester from multiple angles.

A connecting block 29 is fixedly connected to the movable plate 20. Both the connecting block 29 and the guide groove 28 are designed in a T shape. The connecting block 29 slides in the guide groove 28. Through the sliding of the T-shaped connecting block 29 in the guide groove 28, the guide groove 28 can guide the movement of the movable plate 20, so that the movable plate 20 can move smoothly and directionally.

[0021] A guide chute 21 is formed in the movable plate 20. A threaded rod 22 is rotatably connected in the guide chute 21. One end of the threaded rod 22 passes through the movable plate 20 and is fixedly connected with a handwheel 23. Two fitting blocks 24 are installed on the threaded rod 22 in a threaded fit manner. A clamping plate 25 is fixedly connected to the fitting block 24. Threads with opposite directions are arranged at both ends of the threaded rod 22, and the two fitting blocks 24 are symmetrically arranged at both ends of the threaded rod 22. The fitting blocks 24 slide in the guide chute 21, and the fitting blocks 24 are in contact with the groove wall of the guide chute 21. The contact between the groove wall of the guide chute 21 and the fitting blocks 24 can play a role in restricting the fitting blocks 24, avoiding the rotation and deflection of the fitting blocks 24 when the threaded rod 22 rotates.

[0022] A usage method of a fixing device for arrester detection, the usage method includes the following steps: Before clamping and fixing the arrester, the staff starts the driving motor 17 to drive the cam 18 to rotate. As the cam 18 rotates, the hinge rod 19 will deflect and rotate, thereby using the hinge rod 19 to push the movable plate 20, prompting the connecting block 29 to slide in the guide groove 28, so that the two movable plates 20 can move smoothly, and then adjusting the distance between the two movable plates 20 to adapt to arresters of different lengths and sizes; After that, the staff then rotates the handwheel 23 to rotate the threaded rod 22, so that the fitting blocks 24 in threaded fit with the threaded rod 22 move along the threaded rod 22. The threads with opposite directions at both ends of the threaded rod 22 enable the two fitting blocks 24 to drive the two clamping plates 25 to move towards each other respectively, so that the clamping plates 25 can clamp the arrester to complete the fixing, avoiding the offset movement during detection. And during the specific detection; The staff can drive the lead screw 5 to rotate by starting the working motor 4, causing the movable block 8 to slide along the lead screw 5 in the protective housing 3 by means of the threaded fit between the threaded sleeve 9 and the lead screw 5, and then driving the sliding sleeve 6 to slide on the guiding column 2, thereby driving the lightning arrester to move up and down and adjusting the working height during detection to meet the actual working requirements. By starting the electric push rod 11 to pull the movable frame 12, the movable frame 12 is caused to slide along the guiding rod 10; With the sliding of the movable frame 12 and by using the meshing of the gear 15 and the fixed rack 13, the fixed rack 13 can make the connecting rod 14 rotate by pushing the gear 15, causing the connecting rod 14 to drive the deflecting plate 16 to rotate, thereby adjusting and changing the deflection angle of the deflecting plate 16, and further changing the orientation of the lightning arrester, so as to facilitate the staff to detect the lightning arrester and to observe the wiring.
