Especially in harsh environments, such as during natural disasters like strong winds and earthquakes, their stability and durability are easily affected, thus increasing the risk of lightning damage. Specifically, existing lightning protection grounding devices often have weak points in their structural design, such as insufficiently firm connection between the base plate and the soil, and the grounding rod being prone to loosening or breaking due to external forces, all of which lead to a decrease in overall stability.

[0033] Example:

[0034] Please refer to Figure 1(Refer to) Figures 2 to 7 This application provides a lightning protection grounding device for power engineering construction, including a base plate 1, multiple reinforcing structures 2, a grounding structure, a support rod 4, a telescopic rod 5, a conductive structure, a lightning attractor 7, and a lightning rod 21; wherein, the multiple reinforcing structures 2 are respectively installed on the bottom corners of the base plate 1; at the same time, the grounding structure is installed at the bottom center of the base plate 1 for burying in the soil and conducting lightning into the soil; and the support rod 4 is installed at the top center of the base plate 1; in addition, the telescopic rod 5 is height-adjustably installed on the top of the support rod 4, and the telescopic rod... 5 can be made of stainless steel; the conductive structure is installed on the top of the telescopic rod 5; the lightning attractor 7 is installed on the top of the conductive structure; the lightning rod 21 is installed on the top of the lightning attractor 7 to capture and guide the lightning current; the lightning rod 21, lightning attractor 7, conductive rod 6, telescopic rod 5, support rod 4, base plate 1, and grounding structure are sequentially and electrically connected, so that the lightning is captured by the lightning rod 21 and sequentially guided to the lightning attractor 7, conductive rod 6, telescopic rod 5, support rod 4, base plate 1, and grounding structure, and finally dispersed into the soil. The cooperative arrangement between the base plate 1, reinforcing structure 2, grounding structure, and lightning attractor 7 makes the use and disassembly of the device more convenient.

[0035] Furthermore, bolts 9, which can be made of high-strength steel, are installed at each corner of the base plate 1. The reinforcement structure 2 includes ground nails 10 for burying in the soil. The ground nails 10 are used to penetrate the soil to increase the overall stability of the device. The top of the ground nails 10 is provided with threaded holes 11 for connecting with the base plate 1. The bolts 9 on the base plate 1 are threadedly connected to the ground nails 10 through the threaded holes 11, thereby forming double reinforcement and effectively resisting the effects of natural disasters such as wind pressure, pull-out force and earthquakes. By setting the reinforcement structure 2 at the bottom of the base plate 1 and threading it with the bolts 9, not only is the overall stability of the device enhanced, but its ability to resist natural disasters such as wind pressure, pull-out force and earthquakes is also improved, ensuring that it can operate stably for a long time in harsh environments. Meanwhile, the grounding structure includes a grounding rod 3 and a lead wire 13. The grounding rod 3 can be made of copper or copper-plated steel, and its bottom is equipped with a pre-embedded plate 12, which facilitates the installation of the device. The lead wire 13 is wound around the outer surface of the grounding rod 3. The design of the lead wire 13 on the grounding rod 3 greatly increases its contact area with the soil, optimizes the path of current conduction into the soil, thereby improving the dispersion efficiency of lightning current and reducing the risk of lightning damage to power engineering buildings. Furthermore, the support rod 4 can be made of aluminum alloy, and its bottom is fitted with a chuck 14. The chuck 14 is installed on the base plate 1 by multiple hexagonal nuts 15. The cooperation between the chuck 14 and the hexagonal nuts 15 further enhances the stability of the device. In addition, the support rod 4 has multiple spaced connecting holes along its height direction; a limiting hole is opened on the middle of one side of the telescopic rod 5, and a limiting block 16 that can be extended or extended is connected in the limiting hole. Specifically, a connecting spring 17 is installed in the limiting hole, and one end of the connecting spring 17 is connected to one end of the limiting block 16; and the limiting block 16 matches the connecting hole and is used to engage or disengage with the connecting hole; the telescopic rod 5 is engaged with the connecting hole on the outer surface of the support rod 4 through the limiting block 16 and the connecting spring 17. When it is necessary to adjust the height of the telescopic rod 5, the limiting block 16 is pressed out of the connecting hole by pressing it, and the telescopic rod 5 is released from the support rod 4 and adjusted to a suitable height. Under the thrust of the connecting spring 17, the limiting block 16 re-enters the connecting hole and limits and fixes the telescopic rod 5, thereby achieving the purpose of flexible adjustment of the telescopic height. Meanwhile, the conductive structure includes a conductive rod 6, a coupling ring 18, and a connecting sleeve 19; the conductive rod 6 is installed on the top of the telescopic rod 5; the coupling ring 18 is sleeved on the conductive rod 6, and the conductive rod 6 can be made of copper or copper-plated steel; the connecting sleeve 19 is installed on the top of the coupling ring 18. Furthermore, the lightning arrester 7 can be made of stainless steel or copper-plated alloy, and the bottom of the lightning arrester 7 is snapped onto the top of the conductive rod 6 via a connecting plate 20, with its bottom located within the inner cavity of the connecting sleeve 19.In addition, a clamp 8 is fitted onto the middle of the lightning detonator 7. By designing the clamp 8 on the lightning detonator 7, the later maintenance and expansion of the device are greatly facilitated. The replacement or upgrading of the parts can be completed quickly without the need for complete disassembly, which reduces the difficulty and cost of maintenance. An extension plate 22 is connected to one side of the clamp 8. A sliding block 23 that can be moved and adjusted along the length direction is connected to the extension plate 22. The clamp 8 can facilitate the later maintenance and replacement of parts of the device, and the operation can be completed quickly without the need for complete disassembly.

[0036] The assembly and installation method of this device is as follows:

[0037] In use, first, connect and fix the base plate 1 and the ground nail 10 with bolts 9 and threaded holes 11 to ensure the bottom of the device is stable; bury one end of the grounding rod 3 with the pre-embedded plate 12 into the soil so that the lead wire 13 on its outer surface is in full contact with the soil; install the support rod 4 and reinforce it with chuck 14 and hexagonal nut 15, then install the telescopic rod 5 and lock the limit block 16 at the height as needed; install the conductive rod 6 on the top of the telescopic rod 5 and fix the lightning trigger 7 with the tie ring 18 and connecting sleeve 19 to ensure smooth electrical connection; install the lightning rod 21 on the top of the lightning trigger 7 to prepare to capture lightning; finally, install the clamp 8 for easy maintenance later.

[0038] In summary, the lightning protection grounding device for power engineering buildings disclosed in this application, through the coordinated arrangement of the base plate 1, the reinforcing structure 2, the grounding structure, and the lightning arrester 7, makes the use and disassembly of the device more convenient. Simultaneously, by setting the reinforcing structure 2 at the bottom of the base plate 1 and connecting it to the reinforcing structure 2 with bolts 9, not only is the overall stability of the device enhanced, but its resistance to wind pressure, uplift, and earthquakes is also improved, ensuring its long-term stable operation in harsh environments. Furthermore, the design of the lead wire 13 on the grounding rod 3 greatly increases its contact area with the soil, optimizing the current conduction path into the soil, thereby improving the lightning current dispersion efficiency and reducing the risk of lightning damage to power engineering buildings. Moreover, the design of the clamp 8 on the lightning arrester 7 facilitates later maintenance of the device, allowing for rapid replacement or upgrade of components without overall disassembly, reducing maintenance difficulty and cost.
