[0002] Insulators are special insulating components that play an important role in overhead transmission lines. They are composed of two major parts: insulating parts and connecting hardware. In the early years, insulators were mostly used on utility poles. Gradually, they developed into high-voltage power line connection towers with many disc-shaped insulators hung on one end to increase the creepage distance. They are usually made of glass or ceramic and are called insulators. Insulators can be divided into suspension insulators and support insulators according to different installation methods. According to the different insulating materials used, they can be divided into porcelain insulators, glass insulators and composite insulators. According to the different voltage levels used, they can be divided into low-voltage insulators and high-voltage insulators.

[0003] However, the high-voltage insulators that are easy to install on the market currently require tightening bolts using ordinary installation methods. The operation process is particularly cumbersome, which increases the burden on the workers. In addition, the workers have to wear protective gloves during the installation process, which makes it inconvenient to install the insulators and reduces the installation efficiency.

[0025] The fixing hole 10 corresponds to the position of the fixing protrusion 7, which is convenient for fixing. The support spring 6 is connected to the edge of the fixing protrusion 7 away from the end of the fixing box 1, which is convenient for driving the fixing protrusion 7 to extend or retract. The inner side of the fixing box 1 is embedded with a base 9, and limiting grooves 8 are symmetrically provided at the four corners of the bottom inner side of the fixing box 1. Limiting blocks are installed at the four corners of the bottom of the base 9 corresponding to the limiting grooves 8, which is convenient for limiting the position of the base 9. Fixing holes 10 are provided at the middle ends of the four side edges of the base 9 corresponding to the fixing grooves 2. A support seat 11 is installed in the middle of the top of the base 9. The top of the support seat 11 is fixedly installed with an insulator body 19, and the outer side edges of the insulator body 19 are equidistantly connected with insulators 18.

[0026] A fixing frame 13 is installed at the four corners of the top of the base 9, and a motor 14 is installed on the bottom side of the top of the fixing frame 13. The motor 14 is installed on the bottom side of the top of the cleaning frame 15 through a connecting rod to facilitate the installation of the motor 14. The transmission end of the motor 14 is connected to the cleaning frame 15. The width of the fixing frame 13 is greater than the width of the cleaning frame 15 when it rotates, which makes it convenient for the motor 14 to drive the cleaning frame 15 to rotate. A mounting support rod 16 is installed on one side edge of the cleaning frame 15, and a cleaning sponge block 17 is installed on the bottom of one side of the mounting support rod 16. The cleaning sponge block 17 is made of flexible material. The cleaning sponge block 17 fits tightly against the surface of the insulator 18 for cleaning more thoroughly. The dust box 12 is clamped on the outside of the support seat 11, and the dust box 12 is clamped and connected in a splicing manner. Half of the dust box 12 is installed with a connecting block 20 on the edge, and the other half of the dust box 12 has a connecting groove 21 at the edge corresponding to the connecting block 20.

[0027] The working principle and usage process of the utility model are as follows: first, the staff installs the insulator body 19 on the top of the support seat 11, and the support seat 11 is fixedly installed in the middle of the top of the base 9. Then, the limit blocks at the four corners of the bottom of the base 9 correspond to the limit grooves 8 at the four corners of the bottom of the fixing box 1 to limit the position of the fixing box 1. The base 9 is fitted and slidably installed inside the fixing box 1. As the base 9 is continuously pressed down, the support spring 6 drives the fixing rod 3 and the fixing protrusion 7 to contract. When the fixing hole 10 and the fixing protrusion 7 correspond to each other, the support spring 6 drives the fixing rod 3 and the fixing protrusion 7 to extend into the fixing hole 10, which saves the time of manual fixing, makes the installation and fixing more convenient, and also makes the position of the base 9 in the fixing box 1 more stable.

[0028] Pin holes 4 are equidistantly formed on the side of the fixing rod 3. A latch 5 is inserted into the pin hole 4 so that the fixing rod 3 and the fixing protrusion 7 are inserted into the fixing hole 10 and cannot be withdrawn. When the insulator 18 needs to be disassembled, the handle on one side of the fixing rod 3 is pulled to insert the latch 5 into another pin hole 4, so that the fixing rod 3 drives the support spring 6 and the fixing protrusion 7 to withdraw from the fixing hole 10;

[0029] After the base 9 is stable, the motor 14 on the bottom side of the top of the fixing frame 13 is started to drive the cleaning frame 15, the mounting rod 16 and the cleaning sponge block 17 to rotate. The cleaning sponge block 17 is in close contact with the surface of the insulator 18 to achieve an effective cleaning effect. The cleaning sponge block 17 is made of a flexible material to prevent the cleaning sponge block 17 from damaging the surface of the insulator 18. The width of the cleaning frame 15 during rotation is smaller than the width of the fixing frame 13 to prevent the outer arm from hitting the fixing frame 13 when the cleaning frame 15 rotates. A dust box 12 is provided at the bottom of the insulator 18. The cleaning sponge block 17 gathers dust into the dust box 12 through rotation, thereby preventing dust from contaminating other parts of the device.

[0030] The dust box 12 is detachable. A connecting block 20 is installed on one side of the dust box 12, and a connecting groove 21 is opened on the other side of the dust box 12. The connecting block 20 and the connecting groove 21 fit tightly together, so that the dust box 12 is connected more tightly and dust will not leak out. At the same time, it is more convenient for the staff to disassemble it, so that the dust in the dust box 12 can be cleaned in time for the next use.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
