[0002] A rod insulator is a common insulating element used in power transmission and distribution systems. It is usually composed of one or more insulating rods, which are made of insulating materials such as glass fiber reinforced plastic or ceramic. The main function of a rod insulator is to support and insulate wires or cables to ensure the safe and reliable operation of the power system. Publication No. CN218299487U discloses a rod-shaped suspension porcelain insulator, including an insulator body, an upper end connector is arranged above the insulator body, a thread groove is provided at the bottom of the upper end connector, an external thread is provided on the upper outer wall of the insulator body, a lower end connector is arranged at the bottom of the insulator body, a rectangular cavity is provided at the upper end of the lower end connector, and a horizontal slide is slidably connected to the inner wall of the rectangular cavity. In the device, a horizontal slide plate that can slide along the inner wall of the rectangular cavity can be used to facilitate the gradual adjustment of the distance between the two connectors on the suspension porcelain insulator, thereby facilitating the installation and use of different types of suspension porcelain insulators, and a damping spring can be used to buffer the vibration during the use of the insulator, thereby reducing the damage to the insulator and extending its service life, and facilitating the direct replacement of the insulator body on the overhead transmission line. However, the insulator is not provided with a protective structure, which makes the insulator vulnerable to contaminants such as dust, sludge, bird droppings, etc., thereby reducing the insulation performance of the insulator. The insulator still has shortcomings and needs to be improved. Utility Model Content

At the same time, when there are a lot of pollutants accumulated on the protective shell 1 2 and the protective shell 2 4, tools can be used to remove the nut 8 from the outer wall of the bolt 7 in turn, and then the bolt 7 can be pulled out from the inside of the mounting hole 6 after removal. After pulling out, the protective shell 1 2 and the protective shell 2 4 can be removed from the outer wall of the rod-type insulator body 1 for cleaning, which is convenient for the staff to use.

[0024] See also Figure 1-4 The protective shell 1 2 is slidably connected to the rod-type insulator body 1, and the protective shell 2 4 is slidably connected to the rod-type insulator body 1. The sliding connection improves the disassembly and assembly efficiency of the protective shell 1 2 and the protective shell 2 4. A sealing ring 9 is fixedly installed at one end of the protective shell 2 4 close to the protective shell 1 2, and a groove 10 is provided at one end of the protective shell 2 close to the protective shell 2 4. The groove 10 and the sealing ring 9 are slidably connected.

The outer walls of both ends of the rod-type insulator body 1 are fixedly installed with retaining rings 16, which effectively prevent insects from entering the interior of the protective shell 1 2 and the protective shell 2 4.

[0025] Embodiment 2

[0026] See also Figure 4The outer walls at both ends of the rod-type insulator body 1 are slidably connected with connectors 11, and the connectors 11 slide on the outer wall of the rod-type insulator body 1 to improve the efficiency of disassembly and assembly of the connectors 11. The outer wall of the connector 11 is symmetrically provided with clamping holes 12, and the outer walls at both ends of the rod-type insulator body 1 are symmetrically provided with circular holes 13.

After being away from the clamping block 15, the restriction on the connector 11 will be released, and then the rod-type insulator body 1 can be removed for replacement. This structure can quickly disassemble the rod-type insulator body 1, thereby making it convenient for the staff to replace the damaged rod-type insulator body 1.

[0027] Working principle: When in use, the rod-type insulator body 1 can be protected by the protective shell 1 2 and the protective shell 2 4. When there are many pollutants accumulated on the protective shell 1 2 and the protective shell 2 4, the nut 8 can be removed from the outer wall of the bolt 7 in sequence using tools, and then the bolt 7 can be pulled out from the inside of the mounting hole 6. After being pulled out, the protective shell 1 2 and the protective shell 2 4 can be removed from the outer wall of the rod-type insulator body 1 for cleaning. When the rod-type insulator body 1 is damaged and needs to be replaced, the block 15 can be pressed into the circular hole 13. During the pressing process, the block 15 will compress the spring 14. After being compressed for a certain distance, the block 15 will move away from the card hole 12. After moving away, the block 15 will release the restriction on the connector 11, and then the rod-type insulator body 1 can be removed for replacement.
