Description

Technical Field

[0001] This utility model relates to the field of lightning rod fixing technology, and in particular to a stainless steel chimney lightning rod fixing device. Background Technology

[0002] In the construction and industrial sectors, stainless steel chimneys are widely used in industrial plants, high-rise buildings, and thermal engineering projects due to their corrosion resistance, high mechanical strength, and long service life. To prevent damage to the chimney and building structure from lightning strikes, lightning rods must be installed on the top of the stainless steel chimney or at a designated height. The stable fixing of the lightning rods depends on a dedicated fixing device. Therefore, the structural rationality and functional reliability of the fixing device directly determine the effectiveness of the lightning protection system and the safety of the chimney.

[0003] Traditional clamp-type structures rely on the axial preload of bolts for fixation. Over long-term use, corrosive media such as rainwater and industrial dust can seep into the threaded fit between the bolts and clamps, causing thread corrosion or wear. This leads to a decrease in bolt preload and a reduction in the tightness of the fit between the clamp and the chimney, and between the clamping plate and the lightning rod. External disturbances such as strong winds, equipment vibrations, and even minor earthquakes can continuously exert lateral or vertical impact forces on the lightning rod. Accumulated forces can easily break through the bolt's clamping limit, causing the lightning rod to shift. In severe cases, it may slip off the clamping plate. Once the lightning rod slips... A falling lightning rod not only leaves the chimney without lightning protection, but it can also injure people or damage equipment below, causing safety accidents. Furthermore, stainless steel has excellent conductivity, and traditional clamp-type structures lack dedicated components for current isolation. When a lightning rod is struck, the powerful lightning current is conducted through the rod to the fixing device. Without effective insulation, some current will be directly transmitted through the metal clamp to the stainless steel chimney body. The electrochemical corrosion effect caused by the lightning current flowing through the chimney accelerates the oxidation of the chimney's inner wall, shortens its service life, and increases maintenance costs. To overcome these disadvantages, this utility model provides a stainless steel chimney lightning rod fixing device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stainless steel chimney lightning rod fixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stainless steel chimney lightning rod fixing device, comprising a first fixing ring, a chimney clamping assembly disposed on the first fixing ring, a first rubber insulating strip fixedly connected to the first fixing ring, a second adjusting chamber fixedly connected to the first fixing ring, a second adjusting rod slidably connected to the second adjusting chamber, a second fixing ring fixedly connected to one end of the second adjusting rod, a third rubber insulating strip fixedly connected to the second fixing ring, a lightning rod clamping assembly disposed on the second fixing ring, a first fixing assembly disposed on one side of the second adjusting chamber, a second adjusting chamber fixedly connected to one side of the first adjusting chamber, a second adjusting rod slidably connected to the second adjusting chamber, and an anti-slip assembly disposed at one end of the second adjusting rod.

[0006] Furthermore, the chimney clamping assembly includes a plurality of first fixing plates fixedly connected to the first fixing ring, and a first threaded hole is provided on one side of the first fixing plate, and a first fixing bolt is threadedly connected to the first threaded hole.

[0007] Furthermore, the lightning rod clamping assembly includes several second fixing plates fixedly connected to the second fixing ring, and a sixth threaded hole is provided on one side of the second fixing plate, and a fourth fixing bolt is threadedly connected to the sixth threaded hole.

[0008] Furthermore, the first fixing component includes a plurality of fourth threaded holes on one side of the second adjusting chamber, and a plurality of fifth threaded holes on one side of the second adjusting rod, wherein third fixing bolts are threadedly connected to the fourth threaded holes and the fifth threaded holes.

[0009] Furthermore, the anti-slip assembly includes a first adjustment chamber fixedly connected to one end of the second adjustment rod, a first adjustment rod slidably connected to the first adjustment chamber, a U-shaped block fixedly connected to one end of the first adjustment rod, a second rubber insulating strip fixedly connected to the U-shaped block, and a second fixing component provided on one side of the first adjustment chamber.

[0010] Furthermore, the second fixing component includes a plurality of second threaded holes opened on one side of the first adjusting chamber, and a third threaded hole opened on one side of the first adjusting rod, and a second fixing bolt is threadedly connected to the third threaded hole and the second threaded hole.

[0011] The beneficial effects of this utility model are: When using this utility model, 1. By setting up anti-slip components, auxiliary limiting can be formed for the lightning rod. In daily use, even if rainwater erosion causes changes in the gap between the components, or is affected by external environmental vibrations such as strong winds or equipment operation vibrations, the U-shaped block can fit against the surface of the lightning rod to provide additional support. Together with the adjustable fixing structure of the first adjusting rod in the first adjusting chamber, the displacement of the lightning rod can be firmly restricted, preventing it from slipping off the stainless steel chimney, ensuring the continuous effectiveness of the lightning protection function, and reducing the safety hazards caused by the detachment of the lightning rod.

[0012] 2. The device forms a multi-point insulation structure through the first, second, and third rubber insulating strips. This structure can completely isolate the lightning rod from the stainless steel chimney. When the lightning rod is struck by lightning and becomes conductive, it can block the path of current conduction to the stainless steel chimney, avoiding equipment damage and electric shock risks caused by the chimney's conductivity. At the same time, it protects the chimney body from current corrosion and extends the overall service life of the chimney and the device. Attached Figure Description

[0018] like Figure 1-3 As shown, the chimney clamping assembly includes several first fixing plates 2 that are fixedly connected to the first fixing ring 1. A first threaded hole 3 is provided on one side of the first fixing plate 2, and a first fixing bolt 4 is threadedly connected to the first threaded hole 3 for clamping and fixing the device to the stainless steel chimney.

[0019] like Figure 1-3 As shown, the lightning rod clamping assembly includes several second fixing plates 19 fixedly connected to the second fixing ring 18. A sixth threaded hole 20 is provided on one side of the second fixing plate 19, and a fourth fixing bolt 21 is threadedly connected to the sixth threaded hole 20 for clamping the lightning rod.

[0020] like Figure 1-3 As shown, the first fixing component includes a plurality of fourth threaded holes 15 opened on one side of the second adjusting chamber 13, and a plurality of fifth threaded holes 16 opened on one side of the second adjusting rod 14. Third fixing bolts 17 are threadedly connected to the fourth threaded holes 15 and the fifth threaded holes 16 for fixing the second adjusting rod 14, which has been adjusted, onto the second adjusting chamber 13.

[0021] like Figure 1-3As shown, the anti-slip assembly includes a first adjusting chamber 6 fixedly connected to one end of the second adjusting rod 14, a first adjusting rod 7 slidably connected to the first adjusting chamber 6, a U-shaped block 8 fixedly connected to one end of the first adjusting rod 7, a second rubber insulating strip 9 fixedly connected to the U-shaped block 8, and a second fixing assembly provided on one side of the first adjusting chamber 6 to prevent the lightning rod from slipping off the stainless steel chimney.

[0022] like Figure 1-3 As shown, the second fixing component includes a plurality of second threaded holes 10 opened on one side of the first adjusting chamber 6, and a third threaded hole 11 opened on one side of the first adjusting rod 7. The third threaded hole 11 and the second threaded hole 10 are threadedly connected to the second fixing bolts 12, which are used to fix the first adjusting rod 7, which has been adjusted, on the first adjusting chamber 6.

[0023] Working Principle: During use, first check the entire device for integrity. After inspection, place the first fixing ring 1 on the designated position on the stainless steel chimney, ensuring the first rubber insulating strip 5 inside the first fixing ring 1 directly adheres to the outer wall of the chimney, initially achieving insulation between the chimney and the device. Then, tighten the first fixing bolt 4 on the first threaded hole 3 on the first fixing plate 2 to compress the first fixing ring 1 against the chimney, thus fixing it in place. Based on the required installation height and position of the lightning rod, push the second adjusting rod 14 to slide within the second adjusting chamber 13, moving the second fixing ring 18 to the corresponding position of the lightning rod. Place the lightning rod in the second fixing ring 18, ensuring the third rubber insulating strip 22 inside the second fixing ring 18 adheres to the surface of the lightning rod, achieving initial insulation between the lightning rod and the second fixing ring 18. Finally, tighten the fourth fixing bolt 21 on the sixth threaded hole 20 on the second fixing plate 19 to further secure the lightning rod with the second fixing ring 18. To prevent the lightning rod from shifting or slipping due to rainwater erosion or external vibration, the first adjusting rod 7 is pushed to slide within the first adjusting chamber 6, causing the inner sides of the U-shaped block 8 to fit against the inner and outer sides of the chimney. The second rubber insulating strip 9 on the inner side of the U-shaped block 8 then fits against the surface of the chimney. The second fixing bolt 12 is screwed into the second threaded hole 10 of the first adjusting chamber 6 and the third threaded hole 11 of the first adjusting rod 7, fixing the position of the first adjusting rod 7. This allows the U-shaped block 8 to provide auxiliary restraint for the lightning rod. When the lightning rod is struck by lightning and becomes conductive, the first rubber insulating strip 5 blocks the current conduction between the first fixing ring 1 and the chimney, the second rubber insulating strip 9 blocks the current conduction between the U-shaped block 8 and the lightning rod, and the third rubber insulating strip 22 blocks the current conduction between the second fixing ring 18 and the lightning rod. These three elements form a multi-point, full-contact insulation structure, completely isolating the current path between the lightning rod and the stainless steel chimney, preventing current conduction through the chimney from causing equipment damage or safety risks.
