Description

Technical Field

[0001] This utility model relates to the field of lightning protection for signal towers, and in particular to a lightning protection structure for signal towers. Background Technology

[0002] Signal towers are the physical backbone of modern wireless communication networks, supporting mobile communication, the Internet of Things, emergency communication, broadcasting, etc. They provide physical support and height for the installation of communication equipment. Signal towers are usually the tallest buildings in an area and are extremely vulnerable to lightning strikes. Installing lightning protection structures on signal towers is of great significance. They are an indispensable safety barrier in signal tower infrastructure and are directly related to the stability of communication systems, equipment safety, personnel safety, and economic losses.

[0003] In existing technologies, the lightning protection structures and installation methods for signal towers are mainly divided into flange bolt connections, tower body clamp connections, and direct welding connections. Flange bolt connections are the main method for installing lightning protection structures on steel structure towers. A base needs to be pre-set at the top of the tower, and then the lightning protection structure is connected to the base using flange bolts. Tower body clamp connections are mainly used for concrete structure towers. Two-half clamps are fastened to the top of the tower, and the lightning arrester support rod is directly welded to the outer wall of the clamp. Direct welding connections are mainly used for steel structure towers, where the lightning protection structure is directly welded to the top of the tower.

[0004] Flange bolt-connected lightning protection structures can only be installed on signal towers with pre-embedded bases, and the flanges need to be customized according to the size of the base, making them unsuitable for scenarios requiring temporary installation; tower clamp-connected lightning protection structures require the clamp shape to be customized according to the structure of the signal tower, resulting in poor structural adaptability; direct welding connections will damage the original structure of the tower, and cannot be adjusted if the positioning is incorrect; thus, the existing signal tower lightning protection structures have poor adaptability and can only be applied to signal towers with specific structures. Utility Model Content

[0005] To address the problem that existing lightning protection structures have poor adaptability and cannot be applied to signal towers with different structural characteristics, this utility model provides a lightning protection structure for signal towers.

[0006] This utility model provides a lightning protection structure for a signal tower, which adopts the following technical solution:

[0007] A lightning protection structure for a signal tower includes a clamping mechanism, a telescopic mechanism, a lightning arrester, a base, and a lead wire. The lightning arrester is mounted on the base, and the lead wire is mounted on the lightning arrester. The telescopic mechanism includes a telescopic cylinder, a telescopic column, and a self-locking assembly. The telescopic cylinder is a hollow structure with one end closed and the other end open. The closed end of the telescopic cylinder is connected to the lightning arrester. The telescopic column is slidably connected inside the telescopic cylinder. The self-locking assembly is installed between the telescopic cylinder and the telescopic column to restrict the retraction of the telescopic column. The clamping mechanism has two sets: the lower set is fixedly mounted on the base, and the upper set is connected to the telescopic column.

[0008] By adopting the above technical solution, the lower clamping mechanism is fixed to the tower body, and the lightning arrester always remains perpendicular to the ground. Due to the different tower structures and tilt angles of different signal towers, the distance between the upper clamping mechanism and the tower body varies after the lower clamping mechanism is fixedly installed behind the tower body. At this time, the telescopic column is in a retracted state. Extending the telescopic column moves the upper clamping mechanism to a position where it abuts the tower body, and then the upper clamping mechanism is fixedly installed on the tower body. The self-locking component restricts the relative displacement between the telescopic column and the telescopic cylinder, making the connection between the telescopic column and the telescopic cylinder more stable. This allows for the adjustment of the distance between the upper clamping mechanism and the tower body, completing the installation of the lightning protection structure. This enables the lightning protection structure to adapt to towers with different tilt angles, improving the adaptability of the lightning protection structure.

[0009] Optionally, the self-locking assembly includes a spring and a self-locking post. The inner wall of the telescopic cylinder has a groove. One end of the spring is connected to the groove and the other end is connected to the self-locking post. The self-locking post is slidably connected to the groove. The surface of the telescopic post near the groove has serrations. The cross-section of the serrations is a right-angled triangle, and the right-angled surface is connected to the surface of the telescopic post. The lower end of the self-locking post is an inclined surface, and its shape matches the inclined surface of the serrations. The self-locking post abuts against the inclined surface of the serrations.

[0010] By adopting the above technical solution, during the extension of the telescopic column, the sawtooth inclined surface pushes the self-locking column to slide upward in the groove, and the spring is compressed. When the self-locking column inclined surface separates from the sawtooth inclined surface, the spring rebounds. Under the action of the spring, the self-locking column inclined surface automatically abuts against the next sawtooth inclined surface. At this time, the side of the telescopic column abuts against the vertical surface of the previous sawtooth, making the telescopic column unable to retract, thus realizing the self-locking of the relative position of the telescopic column and the telescopic cylinder, and improving the stability of the lightning protection structure.

[0011] Optionally, the self-locking assembly further includes an adjusting rod. The side wall of the self-locking column has a slot, and the upper surface of the slot is inclined. The adjusting rod is slidably connected inside the telescopic cylinder and installed in a direction perpendicular to the self-locking column. The end of the adjusting rod that abuts against the self-locking column is inclined and the inclination angle is consistent with the inclined surface of the slot of the self-locking column.

[0012] By adopting the above technical solution, when the telescopic column needs to retract during the installation of the lightning protection structure, the adjusting rod is pushed towards the self-locking column. The inclined surface of the adjusting rod abuts against the inclined surface of the self-locking column's latch, thereby pushing the self-locking column upward and releasing the self-locking between the telescopic column and the telescopic cylinder. After the telescopic column position is adjusted, the adjusting rod is moved out of the self-locking column's latch, and the spring rebounds, pushing the self-locking column downward to re-lock against the telescopic column, making the telescopic column position adjustment process more convenient.

[0013] Optionally, the telescopic cylinder has a connecting groove at its closed end. The shape of the connecting groove matches the cross-sectional shape of the lightning arrester. The connecting groove is fitted onto the lower end of the lightning arrester, and the telescopic cylinder is slidably connected to the lightning arrester through the connecting groove.

[0014] By adopting the above technical solution, the telescopic cylinder moves on the lightning arrester, which drives the telescopic column and clamping mechanism to move up and down. This allows the position of the upper clamping mechanism in the vertical direction to be adjusted, enabling the upper clamping mechanism to be installed at different positions on the tower body, further improving the adaptability of the lightning protection structure.

[0015] Optionally, the clamping mechanism includes a clamping plate, a fixing plate, and reinforcing bolts. The fixing plate is an L-shaped plate, with the outer side of the upper fixing plate mounted on the telescopic column and the outer side of the lower fixing plate mounted on the base. The inner side of the fixing plate abuts against the outer side of the tower body. The clamping plate is an L-shaped plate, and the clamping plate is detachably connected to the fixing plate by the reinforcing bolts. The outer side of the clamping plate abuts against the inner side of the tower body.

[0016] By adopting the above technical solution, after the fixing plate is abutted against the tower body, the clamping plate and the fixing plate are connected by the reinforcing bolts, so that the tower body is clamped between the clamping plate and the fixing plate. Tightening the reinforcing bolts makes the clamping plate and the reinforcing plate press against the tower body, and the lightning protection structure can be installed on the tower body, which simplifies the installation process and reduces the amount of high-altitude work.

[0017] Optionally, both ends of the clamping plate and the fixing plate are provided with moving grooves, the width of which is the same as the cross-sectional diameter of the reinforcing bolt, and the reinforcing bolt is slidably connected in the moving groove.

[0018] By adopting the above technical solution, the reinforcing bolts can move within the moving groove. By adjusting the installation position of the reinforcing bolts, the clamping mechanism can be adapted to towers of different widths, further improving the adaptability of the lightning protection structure.

[0019] Optionally, the clamping mechanism further includes a rotating assembly, which includes a connecting rod, a connecting block, and a rotating groove. The connecting block is respectively installed on the telescopic rod and the base. The rotating groove is formed on the connecting block and is spherical in shape. One end of the connecting rod is spherical and its size is adapted to the rotating groove. The spherical end of the connecting rod is rotatably connected in the rotating groove, and the other end is connected to the fixed plate.

[0020] By adopting the above technical solution, the connecting rod can rotate at any angle with the rotating groove as the center, thereby driving the reinforcing plate to rotate and adjusting the installation angle of the reinforcing plate, so that the installation angle of the reinforcing plate can be adapted to different tower bodies, thus improving the adaptability of the lightning protection structure.

[0021] Optionally, the rotating assembly further includes a clamp, the connecting block is cylindrical, and the clamp is installed on the outer wall of the connecting block near the connecting rod.

[0022] By adopting the above technical solution, after the installation angle of the reinforcing plate is adjusted, the clamp is tightened so that the inner wall of the rotating groove abuts against the spherical end of the connecting rod, which can restrict the rotation of the connecting rod, fix the installation angle of the reinforcing plate, and improve the stability of the lightning protection structure.

[0023] Optionally, the rotating assembly further includes a limiting part, wherein the limiting part is formed by a protrusion on the outer wall edge of the connecting block near the connecting rod.

[0024] By adopting the above technical solution, when the clamp is in a relaxed state, the clamp can slide on the outer wall of the connecting block, and the limiting part can restrict the displacement of the clamp, reducing the risk of the clamp falling off.

[0025] Optionally, a protective mechanism is also included, comprising a protective cylinder, a limiting block, and a folding plate. The protective cylinder is a rectangular sleeve structure with its internal hollow portion conforming to the outer wall of the telescopic cylinder. The protective cylinder is slidably connected to the outer wall of the telescopic cylinder. The folding plate is rotatably connected to one end of the protective cylinder near the fixed plate and located outside the protective cylinder. The limiting block is installed on one end of the telescopic cylinder near the fixed plate.

[0026] By adopting the above technical solution, the protective cylinder is moved closer to the fixed plate, so that the protective cylinder is fitted around the telescopic component. The folding plate is rotated so that the folding plate is perpendicular to the telescopic rod. At this time, the limiting block abuts against the folding plate, limiting the rotation angle of the folding plate. This reduces the risk of instability in the installation of the lightning protection structure due to accidental contact with the adjustment rod after the lightning protection structure of the signal tower is installed.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] The clamping mechanism can be adjusted to fit the tower structure, making it compatible with various steel structure signal towers.

[0029] The lightning protection structure can be detachably installed on the signal tower. The installation method is simple, and it is easy to replace or maintain, reducing the amount of high-altitude work.

[0030] It can be installed on the tower without a pre-set base, making it suitable for scenarios where signal towers need to be temporarily equipped with lightning protection structures. Attached Figure Description

The limiting block 530 is a rectangular block, which is fixedly connected to one end of the telescopic cylinder 320 close to the fixed plate 430, and its thickness is greater than the length of the extended part of the adjusting rod 334.

[0041] The implementation principle of a signal tower lightning protection structure according to this utility model embodiment is as follows:

[0042] During the installation of the lightning protection structure, rotate the connecting rod 452 of the lower clamping mechanism 400 to adjust the angle of the fixing plate 430 so that the inner side of the fixing plate 430 abuts against the tower body. Then, abut the outer side of the clamping plate 420 against the tower body. Insert the same reinforcing bolt 440 into the moving groove 410 on one side of the fixing plate 430 and the clamping plate 420. Move the reinforcing bolt 440 in the moving groove 410 to the position where it abuts against the tower body. Tighten the reinforcing bolt 440 so that the inner side of the fixing plate 430 and the tower body abut against the tower body. The outer side of the clamping plate 420 simultaneously presses against the tower body, and the same applies to the other side. After the clamping plate 420 is fixed, the angle of the lightning arrester 100 can be adjusted by rotating the connecting rod 452 in the rotating groove 453, so that the lightning arrester 100 is adjusted to a vertical state. The clamping clamp 454 is tightened by bolts, so that the inner wall of the rotating groove 453 presses against the spherical end of the connecting rod 452, thereby restricting the rotation of the connecting rod 452 and keeping the lightning arrester 100 in a vertical state. The lower clamping mechanism 400 is then installed.

[0043] Pulling the telescopic column 310 towards the tower body moves the upper clamping mechanism 400. During the movement of the telescopic column 310, the inclined surface of the sawtooth 333 pushes the self-locking column 332 upward, compressing the spring 331. When the telescopic column 310 moves to the position where the inclined surface of the self-locking column 332 separates from the inclined surface of the sawtooth 333, the spring 331 rebounds. Under the action of the spring 331, the inclined surface of the self-locking column 332 automatically abuts against the inclined surface of the next sawtooth 333. At this time, the side of the telescopic column 310 abuts against the vertical surface of the previous sawtooth 333, preventing the telescopic column 310 from retracting, thus achieving... The telescopic column 310 and the telescopic cylinder 320 are self-locking in relative position. When the telescopic column 310 needs to retract during the position adjustment process, the adjusting rod 334 is pushed towards the self-locking column 332. The inclined surface of the adjusting rod 334 abuts against the inclined surface of the self-locking column 332, thereby pushing the self-locking column 332 to move upward and release the self-locking between the telescopic column 310 and the telescopic cylinder 320. After the telescopic column position is adjusted, the adjusting rod 334 is moved out of the self-locking column 332. The spring 331 rebounds and pushes the self-locking column 332 downward to re-lock the telescopic column 310.

[0044] The telescopic column 310 moves the clamping mechanism 400 to the position of the tower body. The connecting rod 452 is rotated to adjust the angle of the fixing plate 430, so that the inner side of the fixing plate 430 abuts against the tower body. Then, the outer side of the clamping plate 420 abuts against the tower body. The reinforcing bolt 440 is inserted into the moving groove 410 of the fixing plate 430 and the clamping plate 420. The reinforcing bolt 440 is then moved within the moving groove 410 to abut against the tower body. The reinforcing bolt 440 is tightened so that the inner side of the fixing plate 430 and the outer side of the clamping plate 420 simultaneously abut against the tower body. The clamp 454 is tightened by the bolts, causing the rotating groove 453 to... The inner wall abuts against the spherical end of the connecting rod 452, improving the stability of the lightning protection structure installation. After the upper clamping mechanism 400 is installed, the protective cylinder 510 is moved closer to the tower body, so that the telescopic column 310 is located inside the protective cylinder 510. Then, the folding plate 520 is rotated inward so that the folding plate 520 is perpendicular to the side wall of the protective cylinder 510. At this time, the folding plate 520 abuts against the limiting block 530, limiting the rotation angle of the folding plate 520. This reduces the risk of instability in the installation of the lightning protection structure due to accidental contact with the adjusting rod 334 after the lightning protection structure of the signal tower is installed, and improves the stability of the lightning protection structure.

[0045] In summary, the clamping mechanism can be adjusted to fit the tower structure, making it suitable for various steel structure signal towers with high adaptability. The lightning protection structure can be detachably installed on the signal tower, making installation simple, easy to replace or maintain, and reducing the amount of high-altitude work. It can be installed on the tower without a pre-set base, making it suitable for scenarios where a lightning protection structure needs to be temporarily added to the signal tower.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
