Description

Technical Field

[0001] This utility model relates to the field of building lightning protection equipment technology, and in particular to a lightning conductor support bracket. Background Technology

[0002] Lightning strikes are a natural disaster that can damage equipment and buildings, cause fires and explosions, and even injure people and livestock. To avoid lightning strikes, lightning protection devices are commonly used to protect equipment and buildings. These devices mainly consist of lightning rods, down conductors, and grounding systems. Lightning strips, lightning rods, and lightning protection networks are some of the most common types of lightning rods.

[0003] Both lightning protection strips and lightning protection nets require the lightning protection conductors to be suspended in the air using lightning protection brackets. Generally, traditional lightning protection conductor brackets mostly adopt an integrated clamping structure, which usually has problems such as the clamping angle not being adjustable, making it difficult to install the lightning protection conductors, poor installation stability, lack of drainage design, easy water accumulation in the clamping part leading to corrosion of the conductor bracket and conductors, and weak wind vibration resistance. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a lightning protection conductor support bracket that provides elastic clamping and self-draining functionality.

[0005] The main contents of this utility model include: a vertical support rod having a first end and a second end that are axially opposite each other. The first end is threadedly connected to a waterproof base component for fixing to the roof, and the second end is threadedly connected to a wire clamping component for installing lightning protection wires.

[0006] The wire clamping component includes a mounting base and two sets of symmetrically arranged clamping arms. The bottom of the clamping arms is integrally formed with the mounting base, and a clamping cavity with an open port is formed between the two clamping arms. A radially protruding limiting step is provided in the middle of the inner side of the clamping arm. The limiting step divides the clamping cavity into an upper wire receiving cavity and a lower adjustment cavity. The inner wall of the wire receiving cavity is provided with an arc-shaped clamping surface adapted to the wire.

[0007] Preferably, the second end of the vertical support rod is adjustablely connected to the mounting base via a nut assembly. The nut assembly includes a first adjusting nut and a second adjusting nut that are threadedly engaged with the second end of the vertical support rod. The second adjusting nut is located in the adjusting cavity and at the bottom of the mounting base. The mounting base has a central through hole, and the second end of the vertical support rod passes through the second adjusting nut, the central through hole, and the first adjusting nut in sequence.

[0008] Preferably, the clamping arm has a drainage slope at the open port, the lower end of the drainage slope is inclined toward the clamping cavity, and the upper and lower ends of the drainage slope have arc transition angles.

[0009] Preferably, there is a gap between the two sets of limiting steps, and the radial end of the limiting step near the gap is provided with a water-guiding rounded corner.

[0010] Preferably, the waterproof base component includes an upper pressure plate and a lower gasket respectively disposed on the upper and lower surfaces of the waterproof membrane sheet, and a flange nut threaded to the first end of the vertical support rod. The first end of the vertical support rod has a limiting part, which abuts against the lower gasket. The rod body of the vertical support rod passes through the lower gasket, the waterproof membrane sheet and the upper pressure plate in sequence, and the bottom surface of the flange nut abuts against the upper pressure plate.

[0011] Preferably, the limiting part is configured as a flat-head structure.

[0012] Preferably, the bottom surface of the flange nut is provided with staggered anti-slip teeth.

[0013] Preferably, the vertical support rod has reinforcing ribs on its outer periphery, and the reinforcing ribs extend axially.

[0014] Preferably, the diameter of the vertical support rod is not less than 6mm.

[0015] The beneficial effects of this utility model are as follows: by adjusting the installation angle between the conductor clamping component and the vertical support rod, the conductor receiving cavity is arranged in accordance with the extension direction of the lightning protection conductor, which facilitates the installation of the conductor. At the same time, the lightning protection conductor can naturally fit the inner arc-shaped clamping surface of the clamping arm during installation, effectively improving the clamping stability of the lightning protection conductor. The open port of the clamping arm is provided with a drainage slope, and there is a gap between the two sets of limiting steps, which helps to guide rainwater to flow down quickly, prevent water accumulation from corroding the lightning protection conductor, and effectively increase the elastic deformation of the two sets of clamping arms during the clamping process, which can quickly open and retract the clamping.

[0023] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, this application proposes a lightning protection conductor bracket, which includes a vertical support rod 1 with an axially opposed first end 11 and a second end 12. The first end 11 is connected to a waterproof base component 2 for fixed connection to the roof, and the second end 12 is connected to a conductor clamping component 3 for clamping the lightning protection conductor. This lightning protection conductor bracket allows for stable installation of the lightning protection conductor on the roof, improving the stability and reliability of the overall lightning protection system during long-term use.

[0025] like Figure 1 As shown, the first end 11 and the second end 12 of the vertical support member 1 are respectively threadedly connected to the waterproof base member 2 and the conductor clamping member 3. Preferably, the outer periphery of the vertical support member 1 is provided with reinforcing ribs (not shown), which extend axially to enhance the bending resistance of the vertical support member 1 and further improve the overall stability of the support. Preferably, the diameter of the vertical support member 1 is not less than 6mm to ensure the foundation support strength of the vertical support member. In a specific embodiment, its diameter can be reasonably adjusted according to the overall load-bearing capacity of the support and the actual use environment. The vertical support member 1 can be made of stainless steel round steel, which has excellent compressive and tensile strength, can provide stable support for the entire lightning protection support, and ensure durability.

[0026] like Figure 1-2As shown, the waterproof base component 2 includes an upper pressure plate 22 and a lower gasket 23 respectively disposed on the upper and lower surfaces of the waterproof membrane sheet 21, and a flange nut 24 threadedly engaged with the first end 11 of the vertical support member 1. The first end 11 of the vertical support member 1 has a limiting part 13. The rod body of the vertical support member 1 passes through the lower gasket 23, the waterproof membrane sheet 21, and the upper pressure plate 22 in sequence, so that the limiting part 13 abuts against the lower surface of the lower gasket 23, and the lower end of the flange nut 24 abuts against the upper surface of the upper pressure plate 22, thus forming a complete waterproof base component. Preferably, the limiting part 13 is designed with a flat head structure, which allows the limiting part 13 to be flush with the lower surface of the waterproof membrane sheet 21, avoiding any protrusions that could affect the circumferential welding of the waterproof membrane sheet 21 to the roof.

[0027] like Figure 1-2 As shown, the upper pressure plate 22 and the lower gasket 23 increase the contact area with the waterproof membrane sheet 21, dispersing the pressure exerted by the flange nut 24 and the limiting part 13 during tightening, preventing local damage to the waterproof membrane sheet 21, and simultaneously providing buffering and sealing functions to prevent rainwater leakage and improve sealing performance. Preferably, the lower end face of the flange nut 24 is provided with staggered anti-slip teeth to increase the friction between the flange nut 24 and the upper pressure plate 22, ensuring a tight engagement with the upper pressure plate 22 during tightening and improving the overall connection stability of the waterproof base component 2.

[0028] like Figure 1-3 As shown, the conductor clamping component 3 includes a mounting base 31 and two sets of symmetrically arranged clamping arms 32. The bottom of the clamping arms 32 is integrally formed with the mounting base 31 to improve the overall connection strength of the conductor clamping component 3. A clamping cavity 34 with an open port is formed between the two clamping arms 32, and the lightning protection conductor is inserted into the clamping cavity 34 from the open port.

[0029] like Figure 1-3 As shown, specifically, the clamping arm 32 has a radially protruding limiting step 33 at the center of its inner side. The limiting step 33 divides the clamping cavity 34 into an upper conductor receiving cavity 341 and a lower adjusting cavity 342. The inner wall of the conductor receiving cavity 341 has an arc-shaped clamping surface adapted to the conductor. The lightning protection conductor is specifically clamped in the conductor receiving cavity 341. The curvature of the arc-shaped clamping surface is configured to match the outer circumferential curvature of the lightning protection conductor, so that the lightning protection conductor can naturally conform to the arc-shaped clamping surface when clamped, thereby improving the clamping stability of the lightning protection conductor. This gives the conductor clamping component 3 good toughness and high strength, enabling it to withstand the tensile force, wind force, and other external forces of the lightning protection conductor during long-term use without easily deforming or being damaged.

[0030] like Figure 1-3As shown, the second end of the vertical support rod 1 is adjustablely connected to the mounting base 31 via a nut assembly. Specifically, the nut assembly includes a first adjusting nut 351 located within the adjusting cavity 342 and a second adjusting nut 352 located at the bottom of the mounting base 31. The mounting base 31 has a through-hole 311 at its center. The threaded holes of the first adjusting nut 351 and the second adjusting nut 352 are coaxially arranged with the through-hole 311. The second end of the vertical support rod 1 passes sequentially through the second adjusting nut 352, the through-hole 311 of the mounting base 31, and the first adjusting nut 351. The second end of the vertical support rod 1 is threadedly connected to both the second adjusting nut 352 and the first adjusting nut 351. By adjusting the length of the second end of the vertical support rod 1 extending into the adjusting cavity 342, the installation height of the conductor clamping component 3 can be adjusted within a certain range to meet the needs of different installation heights of the lightning protection conductor.

[0031] like Figure 1-3 As shown, the conductor clamping component 3 is also adjustablely connected to the second end 12 of the vertical support rod 1 via a nut assembly 35. Specifically, the mounting base 31 is constrained between the second adjusting nut 352 and the first adjusting nut 351, and the mounting angle of the mounting base is adjustable. This allows the installation angle of the conductor clamping component 3 to be adjusted according to the extension direction of the lightning protection conductor. The angle adjustment is convenient, ensuring that the direction of the conductor receiving cavity 341 is consistent with the extension direction of the lightning protection conductor, reducing the installation difficulty and time cost of the lightning protection conductor. Simultaneously, when the lightning protection conductor is subjected to external forces (such as wind force, stress generated by thermal expansion and contraction of the conductor), the stress can be dispersed and transmitted along the structure of the support, avoiding stress concentration at a single point, thereby effectively improving the stability of the lightning protection conductor installation.

[0032] like Figure 1-3 As shown, preferably, the two sets of clamping arms 32 are provided with drainage slopes 321 at the open ports. The lower end of the drainage slopes 321 is inclined towards the clamping cavity 34, and the inclination angle is set between 25° and 45°. The upper and lower ends of the drainage slopes 321 have arc-shaped transition angles to improve the smoothness of the process of the lightning protection wire being inserted into the wire receiving cavity 341 from the open port, and the drainage slopes 321 can guide rainwater to flow down quickly to prevent water accumulation. In this embodiment, the inclination angle of the drainage slopes is set to 30°.

[0033] like Figure 1-3 As shown, preferably, there is a gap 331 between the limiting steps 33 of the two sets of clamping arms 32 to increase the elastic deformation of the two sets of clamping arms, ensuring that the two sets of clamping arms 32 can quickly open and quickly retract to clamp, thereby improving the deformation clamping force and the installation firmness of the lightning protection wire. Furthermore, the radial end of the limiting step 33 near the gap 331 is provided with a water-guiding rounded corner to guide rainwater to flow down from the gap and prevent water accumulation from corroding the bracket and the lightning protection wire.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
