[0002] Electrical equipment refers to the collective term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. These devices play a crucial role in the normal operation and transmission of the power system, providing great convenience to our lives and production. However, existing electrical equipment used outdoors may be damaged by lightning strikes during thunderstorms, thus requiring lightning protection devices. The "lightning protection device for electrical equipment" disclosed in application number "CN221747948U" represents an increasingly mature technology. It features a sliding rod and groove design that prevents the crossbar from swaying violently during displacement; a fixing block that provides double reinforcement for installation; and a screw sleeve that ensures double... The screw rotation can simultaneously drive two threaded sleeves to move the corresponding crossbars. The ground stakes strengthen the connection between the bottom of the lightning protection device and the ground. However, this lightning protection device has the following drawbacks: While the sliding rods and grooves facilitate installation and provide lightning protection, the simple structure results in insufficient protection. Therefore, a lightning protection device that provides better protection and extends service life is necessary. Furthermore, the bolted connection requires drilling, hindering installation. Therefore, a lightning protection device that improves installation convenience is also necessary. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a lightning protection device for electrical equipment, including a lightning protection component 100 and an installation component 200;

[0023] The lightning protection component 100 includes two mounting plates 101, and several dampers 102 are detachably installed between the two mounting plates 101. Each damper 102 has a shock-absorbing spring 103 sleeved on its side surface. One of the mounting plates 101 has a mounting hole 104 at its upper end. A lightning arrester base 105 is installed inside the mounting hole 104. A lightning rod 106 is detachably installed at the upper end of the lightning arrester base 105. A spring grounding wire 107 is connected to the lower end of the lightning arrester base 105.

[0024] Mounting assembly 200 includes a fixing plate 201 mounted on one side of two mounting plates 101. The fixing plate 201 is internally connected to a lead screw 202 and a guide rod 203. The side surfaces of the lead screw 202 and the guide rod 203 are each connected to two clamping blocks 204. The opposing surfaces of the two clamping blocks 204 are each embedded with an anti-slip plate 205. The surface of the anti-slip plate 205 is fixedly connected with an anti-slip ridge 206.

[0025] In one specific embodiment, the lightning protection component 100, in conjunction with the installation component 200, not only improves the shock absorption and protection effect of the lightning protection device, thereby extending its service life, but also facilitates quick installation of the lightning protection device without drilling, thus improving its ease of use. In use, first, the two clamping blocks 204 are held within the electrical equipment. Then, the screw 202 is turned clockwise or counterclockwise. The guide rod 203, in conjunction with the screw 203, controls the two clamping blocks 204 to move along the screw 202. The guide rod 203 moves closer to or further away from each other to perform lifting and lowering operations, and can be clamped by the clamping block 204. This improves the ease of use of the lightning protection device. In use, the lightning arrester 105, lightning rod 106 and spring grounding wire 107 can conduct lightning into the ground to achieve the lightning protection effect. When the two mounting plates 101 are subjected to force and vibration, the presence of the damper 102 and the shock-absorbing spring 103 can achieve the shock absorption effect. Therefore, it can reduce the vibration of the mounting plate 101 and its internal lightning arrester 105, thereby extending the service life of the lightning protection device.

[0026] Please see Figure 2 and Figure 3 Both mounting plates 101 have several first screw holes 111 on their surfaces. The upper and lower ends of several dampers 102 are fixedly connected with bolts 112, which are threaded into the first screw holes 111.

[0027] In one specific embodiment, the bolt 112 is threaded into the first screw hole 111, thereby enhancing the connection strength between the damper 102 and the mounting plate 101. At the same time, the damper 102 can be disassembled by removing the bolt 112.

[0028] Please see Figure 2 and Figure 3 Two guide blocks 121 and limit blocks 122 are fixedly connected to one side of each of the two mounting plates 101.

[0029] In one specific embodiment, the guide block 121, in conjunction with the limiting block 122, can improve the connection stability between the mounting plate 101 and the fixing plate 201.

[0030] Please see Figure 2 and Figure 3 The upper end of the lightning arrester base 105 is provided with a plug hole 131, and the lightning rod 106 is plugged into the plug hole 131.

[0031] In one specific embodiment, the lightning rod 106 is inserted into the insertion hole 131, which can improve the ease of installation and disassembly of the lightning rod 106, and can be replaced when the lightning rod 106 is damaged.

[0032] Please see Figure 4 The surface of the fixing plate 201 has two guide grooves 211, and the two guide blocks 121 are slidably connected inside the guide grooves 211.

[0033] In one specific embodiment, when the guide block 121 moves up and down along the guide groove 211, the smoothness and stability of the mounting plate 101 moving up and down along the fixing plate 201 can be improved.

[0034] Please see Figure 4 The surface of the clamping block 204 is provided with a second screw hole 221 and a guide hole 222. The lead screw 202 is threaded into the inside of the second screw hole 221, and the guide rod 203 is inserted into the inside of the guide hole 222.

[0035] In one specific embodiment, the lead screw 202 is threaded into the second screw hole 221. By turning the lead screw 202, it can be raised and lowered along the second screw hole 221, thus improving the ease of raising and lowering the clamping block 204 and enhancing the clamping stability of the two clamping blocks 204.

[0036] Please see Figure 4 Each of the two clamping blocks 204 has a connecting groove 231 on its opposite surface, and an anti-slip plate 205 is installed inside the connecting groove 231.

[0037] In one specific embodiment, the connecting groove 231 can limit the installation of the anti-slip plate 205 and improve the ease of disassembly and replacement of the anti-slip plate 205.

[0038] Working principle: In use, firstly, the two clamping blocks 204 are controlled to clamp inside the electrical equipment. Then, the screw 202 is turned clockwise or counterclockwise. With the help of the guide rod 203, the two clamping blocks 204 can be moved along the screw 202 and the guide rod 203. This allows the two clamping blocks 204 to move closer or further apart to raise and lower, thereby clamping the equipment and improving the ease of use of the lightning protection device. In use, the lightning arrester base 105, lightning rod 106, and spring grounding wire 107 can conduct lightning into the ground to achieve the lightning protection effect. When the two mounting plates 101 are subjected to force and vibration, the damper 102 and the shock-absorbing spring 103 can achieve the shock absorption effect, thereby reducing the vibration of the mounting plate 101 and its internal lightning arrester base 105, and extending the service life of the lightning protection device.
