[0002] With the continuous development and improvement of the power system, the safe and stable operation of high-voltage transmission lines has become a vital link in the power system. In high-voltage transmission lines, lightning arresters are important devices that protect electrical equipment from damage caused by lightning overvoltage. Their performance directly affects the safety and reliability of the entire power system. However, traditional lightning arresters have problems such as complex installation and inconvenient maintenance, especially in remote areas or harsh environments. These problems are more prominent.

[0003] In recent years, in order to improve the installation efficiency and maintenance convenience of lightning arresters, the industry has begun to research and develop new structures of lightning arresters. Among them, high-voltage power grid lightning arresters that are easy to disassemble and install have attracted widespread attention because they can significantly reduce installation time and costs, while improving the efficiency of later maintenance. This type of lightning arrester usually adopts a modular design, and through the optimization of the connection method (such as quick connectors, plug-in interfaces, etc.), the lightning arrester can be quickly replaced or repaired without power outages, which greatly facilitates the work of on-site operators.

[0004] However, when repairing and replacing this type of lightning arrester, it is still necessary to manually climb onto the high-voltage power grid rack and perform replacement and maintenance work on it. The operation process has certain risks. For example, Chinese patent application CN202410265152.8 discloses a high-voltage power grid lightning arrester that is easy to disassemble and install. Although it uses a fixing column to make the upper end fixing column connected to an upper end seat threadedly fixedly connected to the upper end of the high-voltage lightning arrester body, and the lower end fixing column connected to a lower end seat threadedly fixedly connected to the lower end of the high-voltage lightning arrester body, it is conducive to installing the high-voltage lightning arrester body through the above-mentioned components, so that the high-voltage lightning arrester body can be conveniently installed and fixed; but the staff still need to climb onto the high-voltage power grid rack to operate, and the risk still exists.

[0005] Therefore, a high-voltage power grid lightning arrester that is easy to disassemble and install is needed to solve the above problems. Summary of the invention

When the lightning arrester moves to the ground, the operator removes the lightning arrester 4 from the pull rope 334, then installs a new lightning arrester 4 on the pull rope 334, and installs a new contact piece 34 on the top of the new lightning arrester 4, and then starts the motor 332 again. The output end of the motor 332 drives the winding wheel 333 to rotate, and the pull rope 334 is wound, so as to lift the new lightning arrester 4. When the top of the lightning arrester 4 enters the connecting tube 31 again, and the contact piece 34 contacts the inner top wall of the connecting tube 31, the motor 332 is stopped, and then the supporting mechanism 2 is moved to support the bottom of the new lightning arrester 4 again.

[0050] like Figure 2 , 3 As shown in Figure 4, the support mechanism 2 includes two slidably arranged support rods 21, the bottom end of the lightning arrester 4 is located between the two support rods 21, the bottom end fixed sleeve of the lightning arrester 4 is provided with a fixed plate 22, the bottom end gap of the lightning arrester 4 is provided with a sliding plate 23, the sliding plate 23 is located on the lower side of the fixed plate 22, a first spring 24 is connected between the sliding plate 23 and the fixed plate 22, the two support rods 21 are arranged on the lower side of the sliding plate 23, the support rods 21 are in contact with the lower side surface of the sliding plate 23, and the contact sheet 34 is made of elastic material.

[0051] Specifically, when the lightning arrester 4 is contacted, the support rod 21 contacts the lower side surface of the sliding disk 23, and at the same time, the support rod 21 contacts the lower end of the lightning arrester 4 to clamp the lower end of the lightning arrester 4; when the lifting member 33 lowers the lightning arrester 4, the two support rods 21 are first slid, and the two support rods 21 are moved away from the lower side of the sliding disk 23, so that the lightning arrester 4 can be lowered from the gap between the two support rods 21; when the lifting member 33 lifts the lightning arrester 4, the lightning arrester 4 is lifted from the gap between the two support rods 21, and after the lightning arrester 4 enters the connecting tube 31, the two support rods 21 move toward each other and move to the lower side of the sliding disk 23 to support the sliding disk 23, thereby supporting the lightning arrester 4.

[0052] Through the setting of the support rod 21, the lightning arrester 4 can be supported in cooperation with the sliding plate 23, the first spring 24 and the fixed plate 22, and the support rod 21 can be moved to lift and lower the lightning arrester in cooperation with the lifting member 33. Moreover, through the setting of the first spring 24, the vibration of the high-voltage power grid frame can be reduced and transmitted to the lightning arrester 4, making the lightning arrester 4 more stable and improving the service life of the lightning arrester 4.

[0053] like Figure 2 , 7As shown in Figure 8, the support rod 21 is connected to the movable member 25, and the movable member 25 includes two symmetrically arranged first electromagnetic slide rails 251. The two ends of the support rod 21 are respectively fixedly connected with first electromagnetic sliders 252, and the two first electromagnetic sliders 252 are respectively slidably connected in the two first electromagnetic slide rails 251, and the first electromagnetic slide rails 251 are fixedly connected to the base 1.

[0054] Specifically, when in use, when the support rod 21 needs to move, the first electromagnetic slider 252 is started, and the first electromagnetic slider 252 slides in the first electromagnetic slide rail 251 , and the first electromagnetic slider 252 drives the support rod 21 to move.

[0055] By providing the moving member 25 , the support rods 21 can be driven to move, so as to facilitate supporting the lightning arrester 4 and enable the lightning arrester 4 to be lifted and lowered in the gap between the two support rods 21 .

[0056] Furthermore, the first electromagnetic slide rail 251 and the first electromagnetic slider 252 are prior art and will not be described in detail.

[0057] like Figure 2 , 8 As shown in Figure 9, a limiting member 26 is respectively provided on each of the support rods 21, and the limiting member 26 includes a first limiting rod 261 and a second limiting rod 262 which are slidably connected to the support rod 21, the ends of the two first limiting rods 261 on the two support rods 21 can abut against each other, and the ends of the two second limiting rods 262 on the two support rods 21 can abut against each other, and the bottom end of the lightning arrester 4 is located between the first limiting rod 261 and the second limiting rod 262.

[0058] Specifically, when the two support rods 21 move toward each other, the two support rods 21 drive the first limiting rod 261 and the second limiting rod 262 to move toward each other. When the support rod 21 contacts the bottom end side of the lightning arrester 4, the ends of the two first limiting rods 261 abut against each other, and the ends of the two second limiting rods 262 abut against each other. The first limiting rod 261 and the second limiting rod 262 cooperate with the support rod 21 to limit the bottom end of the lightning arrester 4.

[0059] By setting the limiting member 26, the bottom end of the arrester 4 can be limited and clamped in cooperation with the support rod 21, so as to prevent the bottom end of the arrester 4 from swinging, thereby making the installation of the arrester 4 more stable.

[0060] like Figure 7 As shown, the base 1 includes two mounting rods 11, the first electromagnetic slide rail 251 is fixedly connected between the two mounting rods 11, a mounting plate 12 is fixedly connected to each mounting rod 11, a connecting shaft 13 is fixedly connected to the top of the mounting plate 12, and the connecting shaft 13 is rotatably connected to the connecting tube 31.

[0061] like Figure 4 , 8 As shown in , the first limiting rod 261 is connected to a moving part 27, and the moving part 27 includes a mounting groove 271 opened on the support rod 21, and a second electromagnetic slide rail 272 is fixedly connected in the mounting groove 271, and a second electromagnetic slider 273 is slidably connected in the second electromagnetic slide rail 272, and the second electromagnetic slider 273 is fixedly connected to the first limiting rod 261, and the second limiting rod 262 is connected to a sliding part 28, and the sliding part 28 includes a slide groove 281 opened in the support rod 21, and a slider 282 is slidably connected in the slide groove 281, and the slider 282 is fixedly connected to the second limiting rod 262, and a second spring 283 is connected between the slider 282 and the slide groove 281.

[0062] Specifically, during use, when there is snow accumulated on the lightning arrester 4, the second electromagnetic slider 273 is started, the second electromagnetic slider 273 slides in the second electromagnetic slide rail 272, the second electromagnetic slider 273 drives the first limiting rod 261 to move, the first limiting rod 261 pushes the bottom end of the lightning arrester 4 to move, and at the same time, the bottom end of the lightning arrester 4 drives the second limiting rod 262 to move, the second limiting rod 262 drives the slider 282 to move, the slider 282 compresses the second spring 283, and at the same time, the top of the lightning arrester 4 drives the connecting tube 31 to tilt, and the connecting tube 31 and the connecting shaft 13 rotate relative to each other, so that the lightning arrester 4 tilts and the snow accumulated on it falls off, and then the second electromagnetic slider 273 is moved to reset the second electromagnetic slider 273, the second electromagnetic slider 273 drives the first limiting rod 261 to reset, and the slider 282 resets under the action of the second spring 283, thereby resetting the lightning arrester 4.

[0063] By setting the moving part 27, the first limiting rod 261 can be moved, driving the bottom end of the lightning arrester 4 to move. At the same time, the rotation connection between the connecting tube 31 and the connecting shaft 13 makes the lightning arrester 4 tilt, so that the snow on the lightning arrester 4 falls off, avoiding the influence of the snow on the normal operation of the lightning arrester 4.

[0064] Furthermore, the second electromagnetic slide rail 272 and the second electromagnetic slider 273 are prior art and will not be described in detail.

[0065] like Figure 2 , 4 As shown, a retaining member 29 is provided at the bottom end of the arrester 4, and the retaining member 29 includes a magnetic disk 291 fixedly mounted on the bottom end of the arrester 4, and an electromagnet 292 is fixedly connected to the bottom end of the first electromagnetic slide rail 251 near the second limiting rod 262, and the electromagnet 292 can be magnetically attracted to the magnetic disk 291, and the lower side surface of one end of the magnetic disk 291 near the electromagnet 292 is an inclined surface.

[0066] Specifically, during use, when the first limiting rod 261 pushes the bottom end of the lightning arrester 4 to move, when the magnetic disk 291 contacts the electromagnet 292, the electromagnet 292 is started, and the electromagnet 292 adsorbs the electromagnet 292, and then the second electromagnetic slider 273 is reset. After the second electromagnetic slider 273 is reset, the electromagnet 292 is stopped, and the second limiting rod 262 pushes the bottom end of the lightning arrester 4 to reset under the elastic force of the second spring 283. At the same time, the lightning arrester 4 collides with the first limiting rod 261 when resetting, so that the snow on the lightning arrester 4 is shaken off.

[0067] By setting the retaining member 29, after the lightning arrester 4 is tilted, the inclination of the lightning arrester 4 is maintained through the adsorption effect of the electromagnet 292 and the magnetic disk 291, and after the first limiting rod 261 is reset, the second limiting rod 262 pushes the lightning arrester 4 to reset, so that the lightning arrester 4 collides with the first limiting rod 261, causing the lightning arrester 4 to vibrate, thereby facilitating the shaking off of the snow thereon.

[0068] Furthermore, the electromagnet 292 is a prior art and will not be described in detail.

[0069] like Figure 7 As shown, a processing mechanism 5 is arranged on the mounting plate 12, and the processing mechanism 5 includes an air box 51 fixedly connected to the mounting plate 12, and a plurality of air holes are opened at equal intervals from top to bottom on one side of the air box 51 close to the lightning arrester 4, and an air nozzle 52 is connected in each of the air holes, and the air box 51 is connected to an air source component 53.
