[0002] Insulators are devices installed between conductors at different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress. Insulators come in many types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting hardware.

[0003] In the prior art, such as the Chinese patent number: CN207381185U, a line column type porcelain insulator, including a porcelain column, an upper steel cap and a lower steel cap, the upper steel cap is located at the top of the porcelain column, and the lower steel cap is located at the bottom of the porcelain column, grooves are provided on both sides of one end of the porcelain column, a slot is provided inside the upper steel cap, and a clamp is provided on the inner wall of the slot, a sealing ring is provided on the surface of the clamp, the top of the porcelain column is connected to the upper steel cap through the groove and the clamp, and the connection between the porcelain column and the upper steel cap is fixed by cement glue. The utility model provides a groove and a clamp, and the porcelain column and the upper steel cap are buckled and connected through the groove and the clamp, and then reinforced by cement glue, which can prevent the use of cement glue alone to connect, resulting in unstable connection, and can effectively enhance the stability of the connection between the porcelain column and the upper steel cap, and ensure the stability of the porcelain column performance. By providing a guide groove on the umbrella skirt, the sundries and water on the surface of the umbrella skirt can be quickly removed, and the self-cleaning effect is good.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that the insulator cannot be firmly installed on the base during use. After long-term use, it will cause it to loosen, affecting power transmission and reducing the working quality of the insulator. In some areas, the insulator will be installed at high places. When it is exposed to severe weather such as hail, the insulator cannot be protected, resulting in damage to the insulator, increasing the subsequent maintenance cost and affecting the service life of the insulator.

[0011] As a preferred embodiment, a plurality of notches are formed on the outer surface of the disc.

[0012] The technical effect of adopting the above further solution is that when the disc rotates horizontally, the multiple slots begin to rotate in a circular shape and drive the multiple cylinders to slide in the multiple slots respectively, so that the cylinders do not deviate from the trajectory.

[0013] As a preferred embodiment, the outer surface of the cylinder is movably embedded in the groove.

[0014] The technical effect of adopting the above further solution is: the cylinder slides by utilizing the rotation of the notch.

[0018] The technical effect of adopting the above further solution is: using multiple springs in conjunction with dampers to perform shock absorption and buffering, thereby protecting the insulator body.

[0019] As a preferred implementation, the bottom of the second hollow column is fixedly connected to one end of the plurality of dampers, and the inner wall of the second hollow column is slidably connected to the outer surface of the first hollow column.

[0020] The technical effect of adopting the above further solution is: when the hollow column 2 is subjected to external force, the hollow column 2 will slide back and forth on the outer surface of the hollow column 1, gradually dispersing the external force, thereby facilitating buffering.

When hail hits the insulator body, the outer hollow column two starts to contact the hail first, and the damper and spring inside the hollow column two are used for buffering and shock absorption, so as to disperse the gravity of the hail falling vertically. When the hollow column two is subjected to external force, the hollow column two will slide back and forth on the outer surface of the hollow column one, gradually dispersing the external force, so as to protect the insulator body from being damaged, thereby preventing the insulator from being damaged by hail, reducing the later maintenance cost, and increasing the service life of the insulator.

A slide groove 113 is provided on one side of the outer surface of the plurality of fixed blocks 105. A movable plate 106 is movably embedded in the slide groove 113. An arc plate 112 is fixedly connected to the outer surface of the movable plate 106. A cylinder 111 is fixedly connected to the bottom of the movable plate 106 near the edge. A plurality of notches 110 are provided on the outer surface of the disk 108. The outer surface of the cylinder 111 is movably embedded in the notch 110.

[0033] In this embodiment, the bottom of the insulator body 101 is first installed inside the hollow threaded column 107. In order to prevent the connection between the hollow threaded column 107 and the insulator body 101 from loosening, the staff turns on the external power supply of the motor 103, starts the motor 103 on the top of the support plate 102, and the output end of the motor 103 starts to rotate forward and drives the first gear 104 to rotate. While the first gear 104 rotates, it drives the second gear 109 to rotate forward. While the second gear 109 rotates horizontally, it drives the disc 108 to rotate. While the disc 108 rotates horizontally, the multiple notches 110 start to rotate in a circular shape, and drive the multiple cylinders 111 to rotate respectively. The plurality of notches 110 slide, and through the continuous sliding of the cylinder 111, the plurality of cylinders 111 respectively drive the movable plate 106 to slide in the slide groove 113 of the fixed block 105, and the movable plate 106 gradually moves toward the center, and the movable plate 106 pushes the arc plate 112 to move forward. Through the continuous positive rotation of the first gear 104, the arc plate 112 gradually moves toward the center of the base 1, and firmly clamps the bottom of the insulator body 101 and the connection between the hollow threaded column 107. At this time, the motor 103 is turned off, so that the insulator can be firmly installed on the base to avoid loosening after long-term use, prevent affecting power transmission, and improve the working quality of the insulator.

[0034] Embodiment 2, as Figure 1-5As shown, a hollow column 2 is fixedly connected to the top of the base 1 near the center, a plurality of dampers 202 are fixedly connected to the top of the hollow column 2, a plurality of springs 203 are fixedly connected to the top of the hollow column 2, one end of the plurality of springs 203 is fixedly connected to a hollow column 201, the bottom of the hollow column 201 is fixedly connected to one end of the plurality of dampers 202, and the inner wall of the hollow column 201 is slidably connected to the outer surface of the hollow column 2.

[0035] In this embodiment, by installing the hollow column 2 as a whole on the top of the base 1, when hail hits the insulator body 101, the outer hollow column 201 first starts to contact the hail, and the damper 202 and spring 203 inside the hollow column 201 are used for buffering and shock absorption, so as to disperse the gravity of the hail falling vertically; when the hollow column 201 is subjected to external force, the hollow column 201 will slide back and forth on the outer surface of the hollow column 2, gradually dispersing the external force, thereby protecting the insulator body 101 from damage, thereby preventing the insulator from being damaged by hail, reducing the subsequent maintenance cost, and increasing the service life of the insulator.

[0036] Working principle: When in use, the staff first installs the bottom of the insulator body 101 inside the hollow threaded column 107. In order to prevent the connection between the hollow threaded column 107 and the insulator body 101 from loosening, the staff turns on the external power supply of the motor 103 and starts the motor 103 on the top of the support plate 102. The output end of the motor 103 starts to rotate forward and drives the first gear 104 to rotate. The first gear 104 rotates while driving the second gear 109 to rotate forward. The second gear 109 rotates horizontally. At the same time, the disk 108 is driven to rotate. When the disk 108 rotates horizontally, the plurality of slots 110 begin to rotate in a circular shape, and drive the plurality of cylinders 111 to slide in the plurality of slots 110 respectively. Through the continuous sliding of the cylinders 111, the plurality of cylinders 111 respectively drive the moving plate 106 to slide in the sliding groove 113 of the fixed block 105, and the moving plate 106 gradually moves toward the center. The moving plate 106 pushes the arc plate 112 to move forward. Through the continuous positive rotation of the first gear 104, the arc plate 112 gradually moves toward the center of the base 1, and firmly clamps the bottom of the insulator body 101 and the connection between the hollow threaded column 107, and at this time, the motor 103 is turned off, so that the insulator can be firmly installed on the base to avoid loosening after long-term use, prevent affecting power transmission, and improve the working quality of the insulator. In order to prevent the insulator body 101 from being damaged by bad weather, the staff can install the hollow column 1 2 as a whole on the top of the base 1. When hail hits the insulator body 101, the outer hollow column 201 first begins to contact the hail, and the damper 202 and spring 203 inside the hollow column 201 are used for buffering and shock absorption, so as to disperse the gravity of the hail falling vertically. When the hollow column 201 is subjected to external force, the hollow column 201 will slide back and forth on the outer surface of the hollow column 2, and gradually disperse the external force, so as to protect the insulator body 101 from being damaged, thereby preventing the insulator from being damaged by hail, reducing the later maintenance cost, and increasing the service life of the insulator.
