Description

Technical Field

[0001] This utility model relates to the field of building lightning protection technology, and in particular to a lightning protection grounding device for ancient buildings. Background Technology

[0002] In the field of building lightning protection technology, the lightning protection grounding device for ancient buildings is an important facility to protect ancient buildings from lightning damage. Its main components typically include lightning rods (such as lightning arresters), down conductors, and grounding devices. Its working principle is to attract lightning through the lightning rods, then conduct the lightning current into the grounding device through the down conductors, and finally dissipate the lightning current into the earth, thereby preventing the ancient buildings from being struck by lightning.

[0003] However, traditional lightning protection grounding devices for ancient buildings have certain technical defects. Taking the lightning rod in its lightning arrester section as an example, there is a possibility of bird strikes during actual use. Birds may collide with the lightning rod for various reasons during flight, which may damage the structure of the lightning rod and affect its normal lightning protection function. For example, the lightning rod may deform or loosen after being struck, thereby reducing its lightning interception effect and increasing the risk of ancient buildings being struck by lightning. In addition, feathers, droppings, and other debris left by birds after striking the lightning rod may affect the conductivity of the lightning rod if not cleaned in time, further weakening the reliability of the lightning protection grounding device. Therefore, this application proposes a lightning protection grounding device for ancient buildings to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a lightning protection grounding device for ancient buildings, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightning protection grounding device for ancient buildings includes a lightning rod structure, which is fixedly installed on the upper end of a mounting bracket. A conductive metal mesh is sleeved around the lightning rod structure. Several conductive connection brackets are symmetrically fixedly installed on the lightning rod structure, and the conductive connection brackets are also fixedly connected to the conductive metal mesh. Each conductive connection bracket consists of an arc-shaped base plate, a mounting connection block, a U-shaped mounting frame, a fixed shaft, a mounting rotating block, a clamping block, and a mounting fixing plate. The mounting connection block is fixedly installed on the outer wall of the arc-shaped base plate. There are two U-shaped mounting frames, which are symmetrically fixedly installed on the outer ends of the mounting connection blocks. There are two fixed shafts, which are respectively fixedly installed inside two U-shaped mounting frames. There are also two mounting rotating blocks, two clamping blocks, and two mounting fixing plates. The two mounting rotating blocks are rotatably mounted on two fixed shafts, the two clamping blocks are respectively fixedly installed on the outer ends of the two mounting rotating blocks, and the two mounting fixing plates are respectively fixedly installed on the outer ends of the two clamping blocks. The two mounting fixing plates are fixedly connected by bolts.

[0008] Preferably, the mounting bracket consists of a second connecting plate, support legs, and an annular mounting plate. Several support legs are symmetrically and fixedly installed at the lower end of the second connecting plate.

The mounting plate is provided with mounting holes, and bolts for fixing the two mounting plates are installed in the mounting holes on the two mounting plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By installing a conductive metal mesh sleeve around the outside of the lightning rod structure, a physical barrier is formed, effectively preventing birds from directly impacting the main body of the lightning rod. This reduces the risk of deformation and loosening of the lightning rod structure due to impacts, while also reducing the impact of feathers, droppings, and other debris on the conductivity of the lightning rod structure. Furthermore, the conductive metal mesh sleeve and the lightning rod structure form an electrical path through a conductive connecting bracket, which can work together to intercept lightning strikes, expanding the lightning interception range and improving the reliability of the lightning protection device. At the same time, the conductive connecting bracket connects the conductive metal mesh sleeve to the lightning rod structure, allowing for easy assembly and disassembly of the conductive metal mesh sleeve, thus facilitating its maintenance and repair.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4As shown, a lightning protection grounding device for ancient buildings includes a lightning rod structure 1, which is fixedly installed on the upper end of a mounting bracket 2. A conductive metal mesh cylinder 4 is sleeved around the lightning rod structure 1. Several conductive connection brackets 3 are symmetrically fixedly installed on the lightning rod structure 1, and the conductive connection brackets 3 are simultaneously fixedly connected to the conductive metal mesh cylinder 4. The conductive connection bracket 3 consists of an arc-shaped base plate 10, a mounting connection block 11, a U-shaped mounting frame 12, a fixed shaft 13, a mounting rotation block 14, a clamping block 16, and a mounting fixing plate 18. The mounting connection block 11 is fixedly installed on the outer wall of the arc-shaped base plate 10. There are two U-shaped mounting frames 12, which are symmetrically fixedly installed on the outer ends of the mounting connection blocks 11. There are two fixed shafts 13, which are respectively fixedly installed inside two U-shaped mounting frames 12. There are also two mounting rotation blocks 14, two clamping blocks 16, and two mounting fixing plates 18. The two mounting rotation blocks 14 are respectively rotatably installed on the two fixed shafts 13. Two clamping blocks 16 are fixedly installed on the outer ends of two mounting rotating blocks 14, and two mounting fixing plates 18 are fixedly installed on the outer ends of two clamping blocks 16. The two mounting fixing plates 18 are fixedly connected by bolts. By sleeved with a conductive metal mesh tube 4 on the outside of the lightning rod structure 1, the conductive metal mesh tube 4 can form a physical barrier, effectively preventing birds from directly hitting the lightning rod body 6, reducing the risk of deformation and loosening of the lightning rod structure 1 caused by the impact, and reducing the impact of the attachment of feathers, droppings and other debris on the conductivity of the lightning rod structure 1. In addition, the conductive metal mesh tube 4 and the lightning rod structure 1 form an electrical path through the conductive connection bracket 3, which can work together to intercept lightning, expand the lightning interception range and improve the reliability of the lightning protection device. At the same time, the conductive metal mesh tube 4 is connected to the lightning rod structure 1 using the conductive connection bracket 3, and the conductive metal mesh tube 4 can be disassembled and assembled through the conductive connection bracket 3, thereby facilitating the maintenance and repair of the conductive metal mesh tube 4.

[0020] Specifically, the lightning rod structure 1 consists of a first connecting plate 5 and a lightning rod body 6. The lightning rod body 6 is fixedly installed on the upper end of the first connecting plate 5. The mounting bracket 2 consists of a second connecting plate 7, support legs 8, and an annular mounting plate 9. Several support legs 8 are symmetrically fixedly installed on the lower end of the second connecting plate 7. The annular mounting plate 9 is fixedly installed on the lower end of several support legs 8. The second connecting plate 7 and the first connecting plate 5 are fixedly connected by bolts. The annular mounting plate 9 is fixedly installed on the ancient building. During installation and use, fasteners can be used to fix the annular mounting plate 9 to the roof of the ancient building. At the same time, a down conductor is used to connect the lightning rod structure 1 to the grounding device.

[0021] Specifically, the arc-shaped base plate 10 on the conductive connection bracket 3 is fixedly mounted on the outer wall of the first connecting plate 5 by bolts. The mounting rotating block 14 has a shaft hole 15, and the mounting rotating block 14 is rotatably mounted on the fixed shaft 13 through the shaft hole 15. One end of the clamping block 16 on the conductive connection bracket 3 has a clamping groove 17. The two clamping blocks 16 are clamped on the longitudinal metal wire of the conductive metal mesh tube 4 through the clamping groove 17. The mounting fixing plate 18 has a mounting insertion hole 19, and the bolts for fixing the two mounting fixing plates 18 are installed in the mounting insertion hole 19 on the two mounting fixing plates 18. The conductive connection bracket 3, the conductive metal mesh tube 4 and the lightning rod structure 1 are made of the same material.

[0022] The working principle of this device is as follows: When lightning occurs, the lightning rod body 6 and the conductive metal mesh tube 4 work together to intercept the lightning. The lightning is conducted through the lightning rod structure 1 and then through the down conductor to the grounding device and dissipates into the earth. The conductive metal mesh tube 4 is fitted around the lightning rod structure 1 and forms an electrical path with the lightning rod structure 1 through the conductive connecting bracket 3. This not only expands the lightning interception range but also acts as a physical barrier to prevent birds from colliding with the lightning rod body 6, reducing the risk of deformation and loosening, and minimizing the impact of feathers, droppings, and other debris on conductivity. The method for disassembling and maintaining the conductive metal mesh tube 4 is as follows: When disassembling, unscrew the bolts on the mounting plate 18 so that the two mounting plates... Separate 18, rotate the mounting rotating block 14 around the fixed shaft 13, thereby causing the clamping block 16 to open, and then remove the conductive metal mesh tube 4 from the outside of the lightning rod structure 1; during installation, first put the conductive metal mesh tube 4 around the outside of the lightning rod structure 1, then rotate the mounting rotating block 14 and the clamping block 16 so that the longitudinal metal wire of the conductive metal mesh tube 4 is placed in the clamping groove 17 of the two clamping blocks 16, thereby making the clamping blocks 16 clamp the longitudinal metal wire of the conductive metal mesh tube 4, and finally use bolts to pass through the mounting holes 19 of the mounting fixing plate 18 to fix the two mounting fixing plates 18, so that the conductive connection bracket 3 is fixedly connected to the conductive metal mesh tube 4.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
