Description

Technical Field

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

[0002] Ancient buildings, as treasures of history and culture, carry rich historical information and cultural value. However, because they are mostly built with flammable and easily damaged materials such as wood and bricks, and usually lack the lightning protection facilities found in modern buildings, they are extremely vulnerable to lightning strikes during thunderstorms. The core task of lightning protection devices for ancient buildings is to provide reliable lightning protection without damaging the original appearance and structure of the ancient buildings, thus ensuring their safety.

[0003] A search revealed Chinese patent CN209642272U, which provides a lightning protection device for ancient buildings in tourist attractions. The bottom surface of the barrel tile in contact with the building should be designed to match the shape of the building to ensure good support. The lightning protection strip should be laid along the ridge, eaves, and other parts of the ancient building that are susceptible to lightning strikes. This ensures that the installation of the lightning protection device is consistent with the preservation of the original appearance of the ancient building, thus providing lightning protection without damaging or violating the principle of restoring the old as it was.

[0004] However, during use, it was found that although the device is fixed to the barrel tile with clips to reduce damage to the building, the method of fixing it to the barrel tile with screws still requires drilling holes in the tile, which causes irreversible damage to the ancient building structure. The installation angle adjustment range of the device's bracket and lightning protection strip is limited, making it difficult to adapt to the complex arched ridge or edge tile structure of the ancient building's top, which is not conducive to the lightning protection of the ancient building. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient lightning protection device for ancient buildings. It is fixed to the top of the ancient building in a non-destructive clamping manner, avoiding the need to drill holes in the ancient building. This fundamentally changes the irreversible damage to the structure of the ancient building, protects the historical features and structural integrity of the ancient building, improves the adaptability of the lightning protection device to various ancient building structures, and ensures the reliability of the lightning protection effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a convenient lightning protection device for ancient buildings, including a sector-shaped block, a frustum block fixed on the bottom surface of the sector-shaped block, a limiting post fixed on the bottom surface of the frustum block, a T-shaped block connected to the upper end of the sector-shaped block, a lightning protection strip provided on the upper end of the T-shaped block, multiple insertion holes respectively opened on the T-shaped block and the sector-shaped block, the T-shaped block and the sector-shaped block are fixedly connected by connecting bolts, and a clamping component is sleeved on the outer peripheral wall of the limiting post;

[0007] The clamping assembly includes a U-shaped block, an arc-shaped block slidably connected to the inner wall of the U-shaped block, two sliding grooves on the U-shaped block, two sliders slidably connected to the U-shaped block, an adjusting stud threadedly connected to the slider, and a pressure block fixed at one end of the adjusting stud.

[0008] Preferably, the upper end of the T-shaped block is provided with a locking block, and multiple arc-shaped anti-blocking blocks are fixedly provided in the concave part of the bottom surface of the locking block, and the bottom surfaces of the multiple arc-shaped anti-blocking blocks abut against the outer peripheral wall of the lightning protection strip.

[0009] Preferably, two fastening studs are inserted into the card block, the upper end of the T-shaped block is threaded to the lower end of the fastening studs respectively, and the top surface of the T-shaped block abuts against the outer peripheral wall of the lightning protection strip.

[0010] By tightening the fastening studs to press the locking block down, the arc-shaped anti-slip block at the concave bottom of the locking block comes into close contact with the outer peripheral wall of the lightning protection strip, increasing the friction and stabilizing the lightning protection strip. This reduces the loosening and displacement of the lightning protection strip during use and ensures its long-term stable operation.

[0011] Preferably, the insertion holes of the sector block are arranged in a ring array structure, and the lower outer peripheral wall of the frustum block is provided with multiple slots in a ring array structure. The bottom surface of the frustum block is rotatably connected to the top surface of the U-shaped block.

[0012] With the above technical solution, since the sockets of the sector blocks are arranged in a ring array, different sockets can be selected, and the relative angle between the T-block and the sector blocks can be adjusted by connecting bolts.

[0013] Preferably, the U-shaped block has two limiting grooves, and a limiting block is slidably connected inside the limiting groove. One end of the limiting block is fixedly provided with a tension spring, and the other end of the tension spring is fixedly connected to the U-shaped block.

[0014] Preferably, a positioning block is provided on one side of the frustum block, and two limiting blocks are fixedly connected to the positioning block respectively. One side of the positioning block is engaged with a corresponding slot, and a handle is fixedly provided on the outer wall of the positioning block.

[0015] The above technical solution enables the positioning block to drive the limiting block to slide in the limiting groove against the tension of the tension spring. At this time, the frustum block can be rotated and adjusted to a suitable angle. After releasing the handle, the restoring force of the tension spring drives the limiting block to slide, so that the positioning block is re-engaged in the slot, thereby achieving angle adjustment and fixation.

[0016] Preferably, two connecting rods are rotatably connected to the U-shaped block, the slider is threadedly connected to the connecting rods, and a handwheel is fixedly provided at the upper end of the connecting rod.

[0017] Using the above technical solution, rotating the handwheel at the upper end of the connecting rod causes the connecting rod to rotate. Since the slider is threadedly connected to the connecting rod, the slider slides up and down in the groove.

[0018] Preferably, one end of the adjusting stud has an internal hexagonal screw hole.

[0019] The above technical solution uses an Allen wrench to turn the Allen screw hole at one end of the adjusting stud, causing the pressure block to move along the adjusting stud, thereby clamping and fixing the top structure of the ancient building and improving installation efficiency.

[0020] The beneficial effects of this utility model are:

[0021] 1. During installation, by adjusting the positions of the T-shaped blocks inserted into different holes of the sector blocks, the relative angle between the T-shaped blocks and sector blocks is changed. The U-shaped blocks are then fitted onto the raised ridge or edge tiles of the ancient building. The pressure blocks on both sides clamp the outer wall of the raised ridge or edge tiles of the ancient building, fixing it to the top of the ancient building in a non-destructive clamping manner. This avoids drilling holes in the ancient building, fundamentally changing the irreversible damage to the ancient building structure, protecting the historical features and structural integrity of the ancient building, improving the adaptability of the lightning protection device to various ancient building structures, and ensuring the reliability of the lightning protection effect.

[0022] 2. Pull the handle on the outer wall of the positioning block to make the positioning block drive the limiting block to slide in the limiting groove against the tension of the spring. At this time, the truncated block can be rotated to adjust to a suitable angle. Then, release the handle. The restoring force of the spring will drive the limiting block to slide, so that the positioning block can be re-engaged into the slot, realizing the adjustment and fixation of the angle. This adapts to the complex top shape of ancient buildings and improves the fit between the lightning protection device and the structure of ancient buildings. Attached Figure Description

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-5 As shown, this embodiment provides a convenient lightning protection device for ancient buildings, including a sector block 100, a frustum block 102 fixed on the bottom surface of the sector block 100, a limiting post 103 fixed on the bottom surface of the frustum block 102, a T-shaped block 200 connected to the upper end of the sector block 100, a lightning protection strip 300 provided on the upper end of the T-shaped block 200, a plurality of insertion holes 101 respectively opened on the T-shaped block 200 and the sector block 100, and the T-shaped block 200 and the sector block 100 are fixedly connected by connecting bolts 104, and a clamping assembly 400 is sleeved on the outer peripheral wall of the limiting post 103;

[0034] The clamping assembly 400 includes a U-shaped block 401, an arc-shaped block 402 slidably connected to the inner wall of the U-shaped block 401, two sliding grooves 403 formed on the U-shaped block 401, two sliders 404 slidably connected to the U-shaped block 401, an adjusting stud 405 threadedly connected to the slider 404, and a pressure block 406 fixed at one end of the adjusting stud 405.

[0035] The upper end of the T-shaped block 200 is provided with a locking block 201. Multiple arc-shaped anti-slip blocks 202 are fixed in the concave part of the bottom surface of the locking block 201. The bottom surfaces of the multiple arc-shaped anti-slip blocks 202 abut against the outer peripheral wall of the lightning protection strip 300. Two fastening studs 203 are inserted into the locking block 201. The upper end of the T-shaped block 200 is threadedly connected to the lower end of the fastening studs 203 respectively. The top surface of the T-shaped block 200 abuts against the outer peripheral wall of the lightning protection strip 300. Tightening the fastening studs 203 presses the locking block 201 down. The arc-shaped anti-slip blocks 202 in the concave part of the bottom surface of the locking block 201 abut tightly against the outer peripheral wall of the lightning protection strip 300, increasing the friction force and realizing the stability of the lightning protection strip 300. This reduces the loosening and displacement of the lightning protection strip 300 during use and ensures the long-term stable operation of the lightning protection strip 300.

[0036] The insertion holes 101 of the sector block 100 are arranged in a ring array structure. The lower outer peripheral wall of the frustum block 102 is arranged in a ring array structure with multiple slots 105. The bottom surface of the frustum block 102 is rotatably connected to the top surface of the U-shaped block 401. Since the insertion holes 101 of the sector block 100 are arranged in a ring array, different insertion holes 101 can be selected, and the relative angle between the T-shaped block 200 and the sector block 100 can be adjusted by connecting bolts 104.

[0037] Two limiting grooves 407 are provided on the U-shaped block 401. A limiting block 408 is slidably connected inside the limiting groove 407. A tension spring 409 is fixedly provided at one end of the limiting block 408, and the other end of the tension spring 409 is fixedly connected to the U-shaped block 401. A positioning block 410 is provided on one side of the frustum block 102. The two limiting blocks 408 are fixedly connected to the positioning block 410 respectively. One side of the positioning block 410 is engaged with the corresponding slot 105. A handle 414 is fixedly provided on the outer wall of the positioning block 410. The positioning block 410 drives the limiting block 408 to slide in the limiting groove 407 against the tension of the tension spring 409. At this time, the frustum block 102 can be rotated. After adjusting to a suitable angle, the handle 414 is released. The restoring force of the tension spring 409 drives the limiting block 408 to slide, so that the positioning block 410 is re-engaged into the slot 105, thereby realizing the adjustment and fixation of the angle.

[0038] Two connecting rods 411 are rotatably connected to the U-shaped block 401. The slider 404 is threadedly connected to the connecting rod 411. A handwheel 412 is fixedly provided at the upper end of the connecting rod 411. Rotating the handwheel 412 at the upper end of the connecting rod 411 causes the connecting rod 411 to rotate. Since the slider 404 is threadedly connected to the connecting rod 411, the slider 404 slides up and down in the groove 403.

[0039] One end of the adjusting stud 405 has an internal hexagonal screw hole 413; by turning the internal hexagonal screw hole 413 at one end of the adjusting stud 405 with an internal hexagonal wrench, the pressure block 406 moves along the adjusting stud 405 to clamp and fix the top structure of the ancient building, thus improving the installation efficiency.

[0040] Working principle: The sector block 100 and the T-block 200 are fixedly connected through multiple insertion holes 101 and connecting bolts 104. During installation, the relative angle between the T-block 200 and the sector block 100 is changed by adjusting the position of the T-block 200 inserted into different insertion holes 101 of the sector block 100, thereby adjusting the installation angle of the lightning protection strip 300 at the upper end of the T-block 200.

[0041] The clamping assembly 400, fitted onto the outer periphery of the limiting post 103, allows for the following operation: U-shaped blocks 401 are fitted onto the raised ridge or edge tiles of the ancient building's roof; slider 404 slides within the groove 403; adjusting studs 405 are moved to the appropriate height; and then the corresponding adjusting studs 405 are rotated to move pressure blocks 406 along them. This allows the pressure blocks 406 on both sides to clamp the outer periphery of the raised ridge or edge tiles of the ancient building's roof. By replacing the appropriate arc-shaped blocks 402 with different roof ridges or edge tiles of ancient buildings, the installation and fit of the arc-shaped blocks 402 are improved, thus achieving clamping and fixing of the ancient building's roof structure. This non-destructive clamping method avoids drilling holes in the ancient building, fundamentally preventing irreversible damage to the structure, protecting the historical appearance and structural integrity of the ancient building, improving the adaptability of the lightning protection device to various ancient building structures, and ensuring the reliability of the lightning protection effect.

[0042] When installing the lightning protection strip 300, it is placed on top of the T-block 200. The fastening stud 203 on the locking block 201 is threadedly connected to the T-block 200. Tightening the fastening stud 203 presses the locking block 201 down. At this time, the arc-shaped anti-slip block 202 at the concave bottom surface of the locking block 201 abuts tightly against the outer peripheral wall of the lightning protection strip 300, increasing the friction and stabilizing the lightning protection strip 300. This reduces the loosening and displacement of the lightning protection strip 300 during use and ensures the long-term stable operation of the lightning protection strip 300.

[0043] When adjusting the installation angle of the lightning protection strip 300, since the insertion holes 101 of the sector block 100 are arranged in a ring array, different insertion holes 101 can be selected. The relative angle between the T-shaped block 200 and the sector block 100 can be adjusted by connecting bolts 104. At the same time, the bottom surface of the frustum block 102 is rotatably connected to the top surface of the U-shaped block 401. Pulling the handle 414 on the outer wall of the positioning block 410 causes the positioning block 410 to drive the limiting block 408 to slide in the limiting groove 407 against the tension of the tension spring 409. At this time, the frustum block 102 can be rotated. After adjusting to a suitable angle, the handle 414 can be released. The restoring force of the tension spring 409 causes the limiting block 408 to slide, so that the positioning block 410 is re-engaged into the slot 105, realizing the adjustment and fixation of the angle. This adapts to the complex top shape of ancient buildings and improves the fit between the lightning protection device and the structure of ancient buildings.

[0044] When using the clamping assembly 400 for fixing, rotating the handwheel 412 at the upper end of the connecting rod 411 causes the connecting rod 411 to rotate. Since the slider 404 is threadedly connected to the connecting rod 411, the slider 404 slides up and down in the slide groove 403, and the adjusting stud 405 moves accordingly. By turning the internal hexagonal screw hole 413 at one end of the adjusting stud 405 with an internal hexagonal wrench, the pressure block 406 moves along the adjusting stud 405, clamping and fixing the top structure of the ancient building, thus improving the installation efficiency.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
