Description

Technical Field

[0001] This utility model relates to the technical field of line protection devices, and in particular to a structure for protecting power communication lines from external damage. Background Technology

[0002] The structure for protecting power communication lines from external damage is a protective device designed to protect power communication lines from damage caused by external human or natural factors, reduce the risk of line failure caused by external forces, and ensure the stability and reliability of the power communication network.

[0003] Because communication cables require stable support to bear their weight during installation, cable trench supports use structures such as brackets, slots, or beams to suspend the cables inside the cable trench, preventing them from being laid directly on the soil, water, or debris at the bottom of the trench. However, since most existing support arms use a single-end fixed and the other end suspended design, this unilateral force-bearing mode makes the support arm prone to tilting, swaying, or even collapse when bearing the weight of the cables for a long time or encountering environmental disturbances such as soil settlement or vibration. This reduces the support strength and makes it difficult to provide layered limiting support, leading to compression and deformation of multiple cables due to their own weight, thus reducing the service life of the cables. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a structure for preventing external force damage to power communication lines. It solves the technical problems of existing technologies where the unilateral force mode causes the support arm to tilt easily when the support bears the weight of the cable for a long time or encounters environmental disturbances such as soil settlement and vibration, reducing the support strength. At the same time, it is not convenient to provide layered limiting support, which leads to the compression and deformation of multiple groups of cables due to their own weight, thus reducing the service life of the cables. The present invention achieves the purpose of improving the support strength of the cables, enabling the orderly separation of the cables, and ensuring the quality of cable use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a structure for preventing external damage to power communication lines, comprising two sets of fixed support plates vertically installed on the inner walls of both sides of the cable trench, and a first support plate, a second support plate, and a third support plate with the same structure provided between the two sets of fixed support plates to provide stable support for the cables. The tops of the first support plate and the second support plate are respectively fixedly installed with lower arc-shaped plates that provide orderly support for multiple sets of cables. The bottoms of the second support plate and the third support plate are respectively provided with upper arc-shaped plates that are positioned corresponding to the lower arc-shaped plates. The top of the upper arc-shaped plates is provided with adjusting screws that move themselves to clamp the cables. The first support plate consists of a support plate 1 and a support plate 2, which are respectively connected to the inner walls of two sets of fixed support plates. One extended end of the support plate 2 is slidably connected to the support plate 1 to accommodate cable trenches of different widths for installation.

[0006] Preferably, the two sets of fixed support plates are internally threaded with multiple sets of first expansion bolts that are threadedly installed on the inner wall of the cable trench, and the inner walls of the two sets of fixed support plates are provided with non-penetrating limiting grooves.

[0007] Preferably, the outer walls of the first support plate and the second support plate at the first support plate are fixedly connected to the inner walls of the two sets of fixed support plates, and the outer walls of the first support plate and the second support plate at the second support plate and the third support plate are slidably connected inside the limiting groove.

[0008] Preferably, the outer walls on both sides of the second support arm plate are limited to the bottom of the limiting groove, and the outer walls of the two sets of fixed support plates are fixedly installed with limiting plates to limit the installation position of the third support arm plate.

[0009] Preferably, the outer walls on both sides of the second support arm plate are fixedly connected to the fixed support plate by a second expansion bolt, and the outer walls on both sides of the third support arm plate are fixedly connected to the limiting plate by a third expansion bolt.

[0010] Preferably, the lower arc-shaped plates at the first support arm plate and the lower arc-shaped plates at the second support arm plate are arranged in an alternating manner, and multiple sets of adjusting screws are respectively threaded into the interior of support plate one and support plate two at the second support arm plate and the third support arm plate.

[0011] Preferably, side plates are fixedly installed on both sides of the bottom of the second support arm plate and the third support arm plate, respectively. A fixing plate for connecting and fixing multiple sets of upper arc plates is slidably connected between the two sets of side plates, and the bottom end of the adjusting screw is rotatably connected to the top of the fixing plate.

[0012] Preferably, the outer walls of the two sets of fixed support plates are fixedly installed with multiple sets of anchor steel parts that are inserted into the cable trench.

[0013] By employing the above technical solution, this utility model provides a structure for protecting power communication lines from external damage, which has at least the following beneficial effects: 1. This utility model features an adjustable-length support arm installed between two sets of fixed support plates. Both ends of the support arm connect to the inner walls of the two sets of fixed support plates. Compared to traditional support arms where one end is suspended, making them prone to tilting and collapse, this design improves the support strength for cables. It also accommodates installation in cable trenches of varying widths. Furthermore, each support arm has an upper and lower arc-shaped plate at its top for separation, allowing for the orderly support of multiple cables. The layered design effectively separates the cables, preventing compression and deformation caused by their own weight, ensuring that the cable sheath and internal core are not mechanically damaged, and guaranteeing the quality of the cables.

[0014] 2. This utility model adopts a detachable installation method for the two sets of top support arms. On the one hand, the top of the support arms is unobstructed, which makes it easy to lay cables on the top of the support arms. On the other hand, the second support arm plate can be reasonably selected for installation according to the number of cables to be laid. At the same time, anchor steel parts are installed on the outer wall of the two sets of fixed support plates and inserted into the soil layer, thereby enabling the installation of fixed support plates and meeting the installation requirements of fixed support plates under different conditions.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 The existing unilateral force-bearing mode of the support structure makes it prone to tilting of the support arm when bearing the weight of cables for extended periods or encountering environmental disturbances such as soil settlement and vibration. This reduces the support strength and makes it difficult to provide layered limiting support, leading to compression and deformation of multiple cable groups due to their own weight, thus reducing the cable's service life. This embodiment provides a structure to prevent external damage to power communication lines, which can improve the support strength of cables, orderly separate cables, and ensure the quality of cable use. Please refer to... Figure 1 - Figure 5 The structure for preventing external damage to the power communication line includes two sets of fixed support plates 1 vertically installed on the inner walls of both sides of the cable trench. Between the two sets of fixed support plates 1 are a first support arm plate 2, a second support arm plate 201, and a third support arm plate 202, all composed of the same structure, providing stable support for the cables. This structure forms a cable support frame, which is equidistantly distributed along the length of the cable trench, enabling support for longer communication cables. The multiple sets of fixed support plates 1 must be kept at the same horizontal height. The tops of the first support arm plate 2 and the second support arm plate 201 are respectively fixedly equipped with lower arc-shaped plates 3 for orderly arrangement and support of multiple sets of cables. The bottoms of the second support arm plate 201 and the third support arm plate 202 are respectively provided with corresponding positions to the lower arc-shaped plates 3. The upper arc plate 4 is provided, and the top of the upper arc plate 4 is provided with an adjusting screw 5 that moves itself to clamp the cable. During the burial of multiple sets of communication cables, the multiple sets of communication cables are first placed in the lower arc plate 3 in sequence, so that the corresponding lower arc plates 3, which are evenly distributed along the length of the cable trench, support the laid cables. After the multiple sets of cables are laid in parallel on the top of the first support plate 2 using hoisting equipment, the second support plate 201 and two sets of fixed support plates 1 can be selected for installation according to the laying needs. This can meet the needs of orderly support of multiple sets of cables. Moreover, the layered design can orderly separate the cables, prevent squeezing and deformation caused by self-weight stacking, ensure that the cable sheath and internal core wires are not mechanically damaged, and ensure the quality of cable use.

[0020] Since the widths of the cable trenches vary, in order to ensure the connection between the outer walls of the multiple sets of support arms and the inner walls of the two sets of fixed support plates 1, and to improve the stability of the multiple sets of support arms for cable support, a sliding design is adopted for the multiple sets of support arms. Taking the first support arm 2 as an example, for instance... Figure 2 - Figure 4As shown, the first support plate 2 consists of a support plate 21 and a support plate 22 that are respectively connected to the inner walls of two sets of fixed support plates 1. One extended end of the support plate 22 is slidably connected to the support plate 21 to accommodate cable trenches of different widths for installation. The two sets of fixed support plates 1 are fixedly installed to the inner walls of the cable trenches by multiple sets of first expansion bolts 11. Since the widths of the cable trenches are different, after installing one set of fixed support plates 1, the support plate 22 can be pulled to extend the width between the two sets of fixed support plates 1, thereby accommodating cable trenches of different widths for installation and improving the versatility of the support bracket.

[0021] To facilitate the parallel installation of multiple sets of cables on the top of the support arm, the two sets of top support arms and the two sets of fixed support plates 1 are now installed in a detachable manner. On the one hand, the top of the support arm is unobstructed, making it easier to install cables in parallel. The cables are laid on top of the support arm. Furthermore, the second support arm plate 201 can be selected and used appropriately based on the number of cables to be laid, such as... Figure 3 - Figure 5 As shown, the two sets of fixed support plates 1 are internally threaded with multiple sets of first expansion bolts 11 that are threaded onto the inner wall of the cable trench. The inner walls of the two sets of fixed support plates 1 are provided with non-penetrating limiting grooves 12. When the number of cables laid is small, it is not necessary to install the second support plate 201 and the fixed support plate 1. The third support plate 202 at the top can be installed directly, so that the bottom end of the third support plate 202 is limited in the bottom of the limiting groove 12 and fixed by the second expansion bolts 7. The upper arc plate 4 at the third support plate 202 clamps the cable at the first support plate 2, ensuring the stability of the cable laying.

[0022] The outer walls of the first support plate 21 and the second support plate 22 at the first support plate 2 are fixedly connected to the inner walls of the two sets of fixed support plates 1 respectively. The outer walls of the first support plate 21 and the second support plate 22 at the second support plate 201 and the third support plate 202 are slidably connected inside the limiting groove 12. The top of the limiting groove 12 is designed to be through, so that the two sets of support plates can be slid inside the limiting groove 12 through the top of the limiting groove 12 to realize the installation of the two sets of support plates and the fixed support plate 1.

[0023] Example 2 Based on Example 1, such as Figure 1 - Figure 5 As shown, the device also includes a limiting plate 13. To limit the movement of the two sets of support arm plates, the limiting plate 13 is installed on the side wall of the fixed support plate 1. This allows the third support arm plate 202 to be limited without affecting the installation of the second support arm plate 201 with the fixed support plate 1. Figure 5As shown, the outer walls on both sides of the second support plate 201 are limited to the bottom of the limiting groove 12. The outer walls of the two sets of fixed support plates 1 are fixedly installed with limiting plates 13 to limit the installation position of the third support plate 202. When there are many cables, the second support plate 201 is limited to the bottom of the limiting groove 12 and fixed by the second expansion bolt 7. With the cooperation of the adjusting screw 5, the upper arc plate 4 fixes the cable on the top of the first support plate 2. The next set of cables is laid in parallel on the top of the second support plate 201. The third support plate 202 is limited to the top of the limiting plate 13. With the cooperation of the adjusting screw 5 at the third support plate 202, the corresponding upper arc plate 4 moves down to clamp the cable at the second support plate 201.

[0024] The outer walls on both sides of the second support arm plate 201 are fixedly connected to the fixed support plate 1 by the second expansion bolts 7, and the outer walls on both sides of the third support arm plate 202 are fixedly connected to the limiting plate 13 by the third expansion bolts 8. The third expansion bolts 8 fix the third support arm plate 202 and the limiting plate 13 to ensure the stability of the third support arm plate 202 after installation.

[0025] To ensure a stable connection between support plate 1 21 and support plate 22, and to guarantee the installation of the adjusting screw 5, the width of the multiple support arm plates is initially set to be relatively wide. This ensures that the adjusting screw 5 is located on one side of the extended end of support plate 22, thus preventing any impact on the sliding of support plate 22. Figure 5 - Figure 6 As shown, the lower arc plate 3 at the first support arm plate 2 and the lower arc plate 3 at the second support arm plate 201 are arranged in an alternating manner. Multiple sets of adjusting screws 5 are respectively threaded into the inside of the support plate 21 and support plate 22 at the second support arm plate 201 and the third support arm plate 202.

[0026] To improve the support effect of multiple bracket arms for communication cables, the two ends of the multiple bracket arms are connected to the inner walls of two sets of fixed support plates 1. This allows the two sets of fixed support plates 1 to support both ends of the bracket arms. Compared to traditional bracket arms where one end is suspended, making them prone to tilting and collapse, this design also allows for installation in cable trenches of varying widths. Figure 6 As shown, side plates 42 are fixedly installed on both sides of the bottom of the support plate 21 and support plate 22 at the second support plate 201 and the third support plate 202, respectively. A fixing plate 41 that connects and fixes multiple sets of upper arc plates 4 is slidably connected between the two sets of side plates 42. The bottom end of the adjusting screw 5 is rotatably connected to the top of the fixing plate 41. Rotating the top of the adjusting screw 5 makes the adjusting screw 5 threadedly connected inside the two sets of support plates, thereby pushing the corresponding fixing plate 41 to slide between the two sets of side plates 42 to adjust the height of the upper arc plate 4, so that the upper arc plate 4 clamps the cable inside the lower arc plate 3.

[0027] Since the sidewalls of the cable trench are either concrete or soil, to meet installation requirements, multiple sets of anchor steel members 6 are installed on the outer walls of the two sets of fixed support plates 1. These anchor steel members 6 are then inserted into the soil layer, enabling the installation of the fixed support plates 1 under different configurations. Figure 3 As shown, multiple sets of anchor steel parts 6, which are inserted into the cable trench, are fixedly installed on the outer wall of the two sets of fixed support plates 1.

[0028] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
