[0002] Lightning protection is the implementation of a series of methods and measures to avoid the potential harm caused by lightning to the human body, buildings, etc.; lightning is a natural discharge phenomenon, and the lightning strike it causes is a natural disaster. It can not only cause damage to equipment and housing facilities, but also cause serious consequences such as fires and explosions, and even cause harm to people and animals. In order to effectively meet this challenge, lightning protection devices such as lightning rods, lightning conductors, lightning nets, lightning strips and lightning arresters are widely used in various occasions. Especially in power engineering buildings, in order to ensure their safety in thunderstorms, it is often necessary to install grounded lightning protection devices. Existing lightning protection grounding devices for power engineering buildings may be unstable when connected to the power engineering building when the device is installed on the power engineering building, so that the device may fall during use.

[0003] In the prior art, a Chinese patent with publication number CN 214313562 U has been proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A lightning protection and grounding device for electric power engineering buildings, comprising a main body, a first connecting plate fixedly connected to the bottom of the main body, a first threaded hole provided on the first connecting plate, a first bolt threadedly connected to the first threaded hole, a telescopic plate fixedly connected to the bottom of the first connecting plate, a second connecting plate fixedly connected to the bottom of the telescopic plate, a groove provided on the main body, a slide groove provided on the side of the groove, a slide rod fixedly connected to the inside of the slide groove, a spring provided on the outer surface of the slide rod, and a first slider slidably connected to the slide rod. The utility model, through the action of the first threaded hole, the first bolt, the telescopic plate and the second connecting plate, enables the device to be relatively tightly connected to the electric power engineering building when it is installed on the electric power engineering building.

[0004] Although the above utility model solves the problem of stability, it is still inconvenient to disassemble and install during maintenance. Different buildings require different lightning protection devices. The above utility model cannot adjust the height of the lightning protection device and has a small scope of application. Utility Model Content

[0005] The purpose of the present utility model is to provide an integrated lightning protection and grounding device for electric power engineering, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An integrated lightning protection and grounding device for power engineering includes an outer rod assembly, an inner rod, and a mounting plate; the outer rod assembly includes: an outer rod, a first down conductor, a second down conductor, and a limit block; the first down conductor is tooth-connected with the second down conductor, one side of the limit block abuts against the second down conductor, and the other side is clamped with the outer rod; a tooth groove is provided on the outer rod for engaging with the first down conductor; the outer rod is fixedly connected to the mounting plate, and the second down conductor abuts against the mounting plate; the inner rod is fixedly connected to the first down conductor.

[0008] The above technical solution is adopted. In this solution, the down conductor is a metal conductor connecting the lightning rod and the grounding body, which is responsible for safely guiding the lightning current received by the lightning receptor into the ground.

[0009] A further improvement of the technical solution of the present utility model is that the first down conductor, the second down conductor and the limiting block form a cylinder with a notch, and the outer diameter of the cylinder is the same as the inner diameter of the outer rod.

[0010] By adopting the above technical solution, the outer diameter of the cylinder is the same as the inner diameter of the outer rod, so the clamping ring can clamp them.

[0011] A further improvement of the technical solution of the present utility model is that the outer rod assembly further comprises a clamping ring, which is clamped in the outer rod and respectively abuts against the second down conductor and the limit block.

[0012] The above technical solution is adopted, in which the clamping ring is C-shaped and clamped in the outer rod. The clamping ring is usually a stainless steel clamping ring, and the surface of the clamping ring is subjected to anti-corrosion and oxidation treatment to increase the service life of the clamping ring.

[0013] A further improvement of the technical solution of the present utility model is that: the grounding body has one side fixedly connected to the mounting plate and the other side fixedly connected to the ground, and the lower end of the grounding body is in a cone shape.

[0014] The above technical solution is adopted. In this solution, the grounding body is generally used to directly contact the soil and realize electrical connection. The grounding body can be an artificial grounding body. The grounding body is generally made of round steel, angle steel, flat steel, steel pipe, etc.

[0017] A further improvement of the technical solution of the present invention is that it comprises a plurality of pull posts, which are circular and evenly distributed on the outside of the insulating member, and are all screwed together with bolts on the outside of the insulating member.

[0018] The above technical solution is adopted. In this solution, it is preferred that the outside of the pull column is a flat column that is one circle larger than the inside. The rope is tied tightly through the pull ring, which not only helps to stabilize the overall position of the device and prevent it from shaking or tilting due to its large size, but also significantly enhances the stability and safety of the device.

[0020] The above technical solution is adopted, in which the specifications and dimensions of the fastening bolts are adapted to the specifications and dimensions of the adjustment holes, forming an indestructible connection structure; the overall stability of the lightning protection device is enhanced, effectively resisting the adverse effects of external wind, rain and vibration, so as to adapt to different environments and installation requirements.

[0021] A further improvement of the technical solution of the present utility model is that it comprises a plurality of baffles which are circular and evenly distributed on the outside of the outer rod.

[0022] By adopting the above technical solution, the baffle in this solution can significantly increase the stability of the lightning protection device. This enhanced stability not only ensures the normal operation of the lightning protection device under severe weather conditions, but also extends the service life of the lightning protection device and reduces the frequency of repair or replacement due to damage.

[0035] The present invention is further described in detail below with reference to the embodiments:

[0036] Example 1

[0037] like Figure 1-Figure 7 As shown, the utility model provides an integrated lightning protection and grounding device for power engineering, including an outer rod assembly 5, an inner rod 4, and a mounting plate 7; the outer rod assembly 5 includes: an outer rod 505, a down conductor 1 501, a down conductor 2 502, and a limit block 503; the down conductor 1 501 is tooth-connected with the down conductor 2 502, one side of the limit block 503 abuts against the down conductor 2 502, and the other side is clamped with the outer rod 505; the outer rod 505 is provided with a tooth groove that engages with the down conductor 1 501; the outer rod 505 is fixedly connected to the mounting plate 7, and the down conductor 2 502 abuts against the mounting plate 7; the inner rod 4 is fixedly connected to the down conductor 1 501.

[0038] In this embodiment, if the down conductor needs to be disassembled, first remove the limit block 503 from the outer rod 505. At this time, the down conductor 2 502 is not blocked by the limit block 503 and its own circumference is smaller than the outer rod 505, so the tooth connection with the down conductor 1 501 is no longer firm, and the down conductor 2 502 tilts to the other side of the outer rod 505. At this time, the down conductor 2 502 can be taken out of the outer rod 505, and then the down conductor 1 501 can be rotated to the side without the tooth groove. At this time, the down conductor 1 501 can be taken out of the outer rod 505.

[0039] like Figure 1-Figure 7 As shown, in this embodiment, preferably, the down conductor 1 501 , the down conductor 2 502 and the limit block 503 form a cylinder with a notch, and the outer diameter of the cylinder is the same as the inner diameter of the outer rod 505 .

[0040] In this embodiment, the outer diameter of the cylinder is identical to the inner diameter of the outer rod 505, allowing the retaining ring 504 to engage them. Each component can be handled individually, reducing the difficulty and cost of overall transportation while also facilitating rapid deployment in different locations or scenarios. Furthermore, this modular design promotes standardized production of accessories, making the production process more efficient and quality control more stringent. During assembly, the seamless connection between components not only simplifies installation steps but also ensures the overall performance and stability of the device.

[0041] like Figure 1-Figure 7 As shown, preferably, the outer rod assembly 5 further includes a snap ring 504, which is clamped in the outer rod 505 and abuts against the second down conductor 502 and the limit block 503 respectively.

[0042] In this embodiment, the retaining ring 504, through the synergistic effect of its various parts, the retaining ring 504, the outer rod 505, the down conductor 1 501, the down conductor 2 502, and the limit block 503 together constitute a stable structural system, ensuring that the outer rod assembly 5 can maintain the correct position and shape during use.

[0043] like Figure 1-Figure 7 As shown, in this embodiment, preferably, it also includes: a grounding body 6, one side of the grounding body 6 is fixedly connected to the mounting plate 7, and the other side is fixedly connected to the ground, and the lower end of the grounding body 6 is in a cone shape.

[0044] In this embodiment, the grounding body 6 is tapered to facilitate the staff to bury the grounding body 6 underground, so that it is in direct contact with the soil and achieves electrical connection. The grounding body 6 is moderately anti-corrosion, generally by applying an anti-corrosion layer. Anti-corrosion materials such as alloy steel, galvanized steel and epoxy resin coating can also be used to separate the metal from corrosive substances in the soil and air, thereby reducing the corrosion rate.

[0045] like Figure 1-Figure 7As shown, in this embodiment, preferably, it also includes: a lightning rod 1, an insulating member 2, and an inner rod 4; the lightning rod 1 is fixedly connected to the insulating member 2; the inner rod 4 is fixedly connected to the insulating member 2, and the lightning rod 1 and the grounding body 6 are connected through a down conductor.

[0046] In this embodiment, the lightning rod 1 is usually made of metal and has a pointed shape. It is installed at a high place on a building. When lightning approaches, the lightning rod 1 can attract the lightning and guide it underground; the outer rod 505 and the inner rod 4 are both made of insulating materials, which can prevent electric shock accidents when someone approaches or touches the outer rod during thunderstorms.

[0047] like Figure 1-Figure 7 As shown, in this embodiment, preferably, a plurality of pull posts 3 are further included. The pull posts 3 are circular and evenly distributed on the outside of the insulating member 2. The pull posts 3 are all screwed onto the outside of the insulating member 2 by bolts.

[0048] In this embodiment, the four pull rings primarily serve as external attachment points for securely tying ropes. Pull rings become crucial when the device is designed to be larger, especially when its height is significantly increased. Tightening the ropes through the pull rings not only helps stabilize the overall position of the device, preventing it from swaying or tilting due to its large size, but also significantly enhances its stability and safety. This design allows operators to easily position and adjust the device, ensuring its stability and reliability during operation.

[0049] like Figure 1-Figure 7 As shown, in this embodiment, preferably, screw holes are provided on the mounting plate 7 , and the fastening bolts 8 are screwed to the mounting plate 7 .

[0050] In this embodiment, a series of precision screw holes are meticulously laid out on the mounting plate 7. These holes are designed to be both stable and rational, ensuring precise connection with the fastening bolts 8. The fastening bolts 8, through their fine threads, tightly engage the screw holes on the mounting plate 7, forming an indestructible connection. This enhances the overall stability of the lightning arrester, effectively resisting the adverse effects of wind, rain, and vibration, and adapting to different environments and installation requirements. Furthermore, this fastening method also facilitates subsequent maintenance and repair work, providing a solid guarantee for the safe operation of the lightning arrester.

[0051] like Figure 1-Figure 7 As shown, in this embodiment, preferably, a plurality of baffles 9 are included, and the baffles 9 are circular and evenly distributed on the outside of the outer rod 505.

[0052] In this embodiment, the baffle 9 can significantly increase the stability of the lightning protection device. This enhanced stability not only ensures the normal operation of the lightning protection device under adverse weather conditions, but also extends the service life of the lightning protection device and reduces the frequency of repair or replacement due to damage.

[0053] The following is a detailed description of the working principle of the integrated lightning protection and grounding device for power engineering. If the down conductor needs to be installed, first put the down conductor 1 501 into the outer rod 505, rotate the down conductor 1 501 so that the side with the tooth groove of the down conductor 1 501 matches the outer rod 505, then put the down conductor 2 502 into the outer rod 505, and the tooth grooves between the down conductor 1 501 and the down conductor 2 502 are also matched, and then put the limit block 503 into the outer rod 505 to abut against the down conductor 2 502; if the down conductor needs to be disassembled, first remove the limit block 503 from the outer rod 505. The down conductor 2 502 is taken out from the outer rod 505. At this time, the down conductor 2 502 has no limit block 503 to resist and its own circumference is smaller than the outer rod 505, so the tooth connection with the down conductor 1 501 is no longer firm. The down conductor 2 502 tilts to the other side of the outer rod 505. At this time, the down conductor 2 502 can be taken out from the outer rod 505, and then the down conductor 1 501 can be rotated to the side without the tooth groove. At this time, the down conductor 1 501 can be taken out from the outer rod 505. If it is necessary to change the height, just change the height of the meshing of the down conductor 2 502 and the down conductor 1 501.

[0054] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
