Then, when the number of insulators needs to be increased, the two adjacent connecting plates 12 can be fitted and then connected by bolts to achieve the connection between the two connecting plates 12. The above method can be used to connect and assemble the insulators, thereby extending the length of the insulator, thereby increasing the distance between the cable and the connecting bracket, increasing the safety distance, and improving the safety performance. When performing maintenance, the nut 08 can be loosened to retract the stud 05 into the locking cavity 03, and the deformation sleeve 07 can be pulled out for replacement.

[0031] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary operation process of increasing the safety performance of the present application is:

[0032] An inner through hole 02 is provided between the two engaging cavities 03, and a lifting ring 06 is formed at the inner end of each stud 05, and a connecting chain 11 is connected between the two lifting rings 06; when the two studs 05 are extended outward by tightening the nut 08, the distance between the two studs 05 can be increased, so that the two lifting rings 06 tighten the connecting chain 11. During daily use, when encountering wind and sand that causes the cable to shake and touch the ceramic umbrella 01 or stones to hit the ceramic umbrella 01, when the ceramic umbrella 01 is broken, the two studs 05 can still be connected together by the connecting chain 11, thereby preventing the cable from falling off after the ceramic umbrella 01 is broken, thereby achieving a stable connection between the bracket and the cable, and preventing the cable from being separated from the bracket due to the breakage of the ceramic umbrella 01.

[0033] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary operation process of increasing the stability performance of the present application is:

[0034] The upper and lower ends of the ceramic umbrella 01 are provided with a plurality of clamping holes 04, each of which is filled with a rubber column 14, and the diameter of the clamping hole 04 gradually increases from the outside to the inside; when the two ceramic umbrellas 01 are assembled, the rubber column 14 can be filled into the clamping hole 04 on one of the ceramic umbrellas 01, and then the other end of the rubber column 14 is extended into the clamping hole 04 on the other ceramic umbrella 01, and then when the two connecting plates 12 are connected, the two ceramic umbrellas 01 are squeezed with the rubber column 14, so that the end of the rubber column 14 can be deformed after being squeezed and fill the clamping hole 04, and the rubber column 14 can be clamped by utilizing the structure of the clamping hole 04 with a large inside and a small outside, so that the rubber column 14 can be utilized to increase the support between the two ceramic umbrellas 01 and increase the stability between the two ceramic umbrellas 01.

[0036] The outer surface of the connecting plate 12 is fixedly connected with a rubber pad 13. When the two connecting plates 12 are connected, the rubber pad 13 can achieve buffering and filling between the two connecting plates 12, so that the two connecting plates 12 fit more closely, avoiding the hidden danger of small collisions between the two connecting plates 12 due to vibration and being transmitted to the ceramic umbrella 01, causing cracks.

[0037] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary operation process of the present application to avoid scratching the ceramic umbrella 01 is:

[0038] The lower end face of the nut 08 is fixedly connected with a protective pad 09; when the nut 08 is tightened, the protective pad 09 can be placed between the nut 08 and the ceramic umbrella 01, thereby preventing the lower end face of the nut 08 from directly contacting the ceramic umbrella 01 and causing scratches, thereby preventing the ceramic umbrella 01 from cracking easily due to scratches.

[0039] A process for preparing a power insulator, the process comprising the following steps:

[0040] S1: Connect the connecting chain 11 to the two lifting rings 06, so that the connecting chain 11 passes through the inner through hole 02, and the two deformation sleeves 07 are respectively located in the two engaging cavities 03;

[0041] S2: Tighten the nut 08 to move the stud 05 outwards, driving the conical bottom 10 to press the deformation sleeve 07 outwards, so that the deformation sleeve 07 is deformed and expanded, and then closely adheres to the engaging cavity 03 to achieve fixation;

[0042] S3: Weld the connecting plate 12 to the outer end of the stud 05 and fix the rubber pad 13 to the outer surface of the connecting plate 12;

[0043] S4: Clean the outer surface of the ceramic umbrella 01 and the welding slag to complete the preparation.

[0044] See attached Figures 1 to 11 From the structure shown, it can be understood that an exemplary operation process of installing the connection chain 11 of the present application is:

[0045] A preparation device is used in the preparation process, which includes a vertical frame 20 rotatably connected to a vertical shaft 21, wherein the upper and lower sides of the vertical shaft 21 are provided with threads of opposite rotation directions, and the upper and lower sides of the vertical shaft 21 are connected to clamps 22, and the two clamps 22 are slidably connected to a suspension rod 28, and a spring is fixed between the suspension rod 28 and the clamps 22, and the inner ends of the two suspension rods 28 are fixed with magnets 27; one of the studs 05 is adsorbed on the magnet 27 located above, so that the other stud 05 hangs down naturally, thereby vertically straightening the connecting chain 11, and then the ceramic umbrella 01 can be moved downward and upward, so that the stud 05 located below passes through the inner through-hole 02, and then the vertical shaft 21 can be rotated so that the vertical shaft 21 drives the two clamps 22 to slide close to each other on the vertical frame 20, so that the two clamps 22 clamp the ceramic umbrella 01 from the upper and lower sides, and at this time, the stud 05 located below will be adsorbed on the magnet 27 located below, thereby completing the process of inserting the connecting chain 11 into the inner through-hole 02.

[0046] See attached Figures 1 to 11 From the structure shown, it can be understood that an exemplary operation process of tightening the nut 08 of the present application is:

[0047] The inner side of the clamping plate 22 is rotatably connected with a nut buckle 23 sleeved on the suspension rod 28, and a toothed ring 24 is fixedly connected to the outer wall of the nut buckle 23. A gear 25 meshing with the toothed ring 24 is rotatably connected to the clamping plate 22. After the nut 08 located above is connected to the stud 05 located above, the stud 05 is adsorbed on the magnet 27 located above. After the ceramic umbrella 01 is sleeved on the connecting chain 11, when the stud 05 located below passes through the ceramic umbrella 01, the nut 08 located below is connected to the stud 05 located below. 5, and then by clamping the two clamping plates 22, the two nut buckles 23 are respectively sleeved on the two nuts 08, and then the motor is used to drive the rotation of the gear 25, so that the gear 25 engages the gear ring 24 to drive the nut buckle 23 to rotate, so that the nut buckle 23 tightens the nut 08, and when the nut 08 is tightened to make the stud 05 extend outward, it will push the suspension rod 28 outward to slide, so that the suspension rod 28 compresses the spring, and when the insulation is removed after the assembly is completed, the spring will drive the suspension rod 28 to reset, preparing for subsequent assembly work.

[0048] See attached Figures 1 to 11 From the structure shown, it can be understood that an exemplary operation process of the rapid positioning of the present application is:

[0049] The vertical frame 20 is rotatably connected to the left end of the mounting frame 29, and the right end of the mounting frame 29 is rotatably connected to the side shaft 30. Two clamping claws 31 are arranged on the upper and lower sides of the side shaft 30. The two inner clamping claws 31 are fixedly connected to the mounting frame 29, and the two outer clamping claws 31 are respectively connected to the upper and lower sides of the side shaft 30. The upper and lower sides of the side shaft 30 are provided with threads with opposite rotation directions; the two connecting plates 12 are respectively clamped between the two clamping claws 31 on the upper and lower sides, so as to fix the positions of the two connecting plates 12. After the nut 08 is tightened, the ceramic umbrella 01 can be moved between the two connecting plates 12. At this time, the outer ends of the two studs 05 are in contact with the two connecting plates 12, so as to achieve rapid positioning. Then, a welding gun can be used to weld the two connecting plates 12 to the outer ends of the two studs 05 respectively to complete the connection.

[0050] In addition, the inner end of the clamp 31 is formed with a positioning edge 32 that is higher than the inner side surface of the clamp 31. When clamping the connecting plate 12, the positioning edge 32 can be used to limit the clamping depth of the connecting plate 12 so that the middle positioning of the connecting plate 12 after clamping can be stably aligned with the stud 05, thereby enabling more accurate welding and positioning.

[0051] See attached Figures 1 to 11 From the structure shown, it can be understood that an exemplary operation process of clamping the ceramic umbrella 01 of the present application is:

[0052] The vertical frame 20 is fixedly connected with a telescopic rod 19, and the telescopic rod 19 is fixedly connected with a crossbeam 15. The crossbeam 15 is rotatably connected with a cross shaft 16. It is assumed that there are threads with opposite rotation directions on both sides of the cross shaft 16. Clamp arms 17 are respectively connected to both sides of the cross shaft 16, and a rubber sleeve 18 is fixedly connected to the inner side of each clamp arm 17. The crossbeam 15 is driven to extend outward by the telescopic rod 19, and then the ceramic umbrella 01 is moved between the two clamp arms 17. Then, the two rubber sleeves 18 are brought close to each other to clamp the ceramic umbrella 01 by the rotation of the cross shaft 16. Then, the crossbeam 15 can be reset to move the ceramic umbrella 01 between the two clamping plates 22, so that the upper and lower ends of the ceramic umbrella 01 are respectively aligned with the two nut buckles 23, so as to facilitate clamping. After the nuts 08 are tightened, the vertical frame 20 can be rotated to drive the assembled ceramic umbrella 01 to move between the two clamped connecting plates 12, thereby completing the automatic conversion and connection of the processing procedures.
