Description

Technical Field

[0001] This invention belongs to the field of spare cable rack technology, specifically relating to a portable, assembled medium-voltage power distribution line OPGW spare cable rack. Background Technology

[0002] Fiber Optic Composite Overhead Ground Wire (OPGW), a special cable integrating communication optical cable and power transmission line grounding functions, is widely used in modern medium-voltage power distribution lines. It serves both as lightning protection grounding for the line and provides a reliable information transmission channel for power system communication, dispatch automation, and relay protection. During the construction of OPGW lines, especially at tension tower locations, a certain amount of surplus optical cable is generated due to junction box installation, splicing operations, and the need to reserve length for possible relocation and maintenance after line operation. If this surplus optical cable is not handled properly, such as being arbitrarily suspended or placed, it is highly susceptible to damage from wind vibration, swaying, or collisions with foreign objects, leading to communication interruptions or even line faults, seriously threatening the safe and stable operation of the power grid.

[0003] The slack cable rack is a key accessory designed to solve the above problems. Its main function is to coil and store the excess portion of the OPGW in an orderly, fixed, and safe manner. A well-designed slack cable rack can effectively prevent excessive bending of the optical cable (ensuring that its bending radius is greater than the specified minimum allowable value), prevent friction with other components, and reduce mechanical stress caused by environmental factors, thereby ensuring the service life of the optical cable and the reliability of communication performance.

[0004] Currently, most OPGW (Operating Power Grid) cable trays on the market are either one-piece welded structures or assembled structures secured with numerous bolts. While one-piece structures are robust, they are bulky, inconvenient to transport, and occupy a significant amount of space during storage and handling. Traditional assembled cable trays, while solving the transportation volume issue to some extent, typically require multiple tools such as wrenches and screwdrivers for assembly, and involve tightening numerous bolts and nuts. In the high-altitude working environment of power line towers, construction workers have limited operating space, making it extremely inconvenient to carry and use multiple tools. Tightening numerous fasteners is time-consuming and labor-intensive, severely impacting construction efficiency. Furthermore, small tools and fasteners pose a risk of falling during high-altitude work, endangering personnel and equipment below. The cumbersome assembly process also increases worker fatigue, indirectly raising safety risks. The bolt tightening torque relies entirely on the experience of the construction workers, potentially leading to inadequate tightening causing loose connections or over-tightening causing stripped threads or deformation, affecting the overall stability and safety of the structure. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable, modular OPGW cable rack for medium-voltage power distribution lines. This rack retains the advantages of modular structures for easy transportation and storage while greatly simplifying the assembly process and reducing reliance on tools.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0029] like Figure 1 As shown, a portable assembled medium-voltage power distribution line OPGW cable rack of the present invention includes a clamping ring 2, a horizontal frame plate 1 and a vertical frame plate 4. The clamping ring 2 is composed of two clamping half rings 18. The right end of the clamping half ring 18 is slidably connected to the horizontal frame plate 1 to adjust the distance between the two clamping half rings 18. The left ends of the two clamping half rings 18 can be connected by a long screw connecting pair 20, thereby fixing the cable rack of the present invention to the pole. A horizontal frame plate 1 is connected to the upper and lower parts of the left side of the vertical frame plate 4. A clamping ring 2 is connected to each horizontal frame plate 1. The upper and lower clamping rings 2 cooperate to stably connect the vertical frame plate 4 to the pole, so as to ensure the stability of the cable support and collection of the cable in this invention. A main cable support plate 3 is slidably connected to the upper and lower parts of the right side of the vertical frame plate 4 for supporting and storing the excess cable from both the upper and lower directions. A fixed connector 6 is fixedly connected to the middle of the right side of the vertical frame plate 4. Telescopic crossbars 5 are connected to the left and right sides of the fixed connector 6. The end of the telescopic crossbar 5 is connected to a side cable support plate 7 for guiding, limiting and storing the excess cable from both the left and right directions.

[0030] Furthermore, in one embodiment, such as Figure 2 As shown, upper support plates 13 are fixedly installed on the upper and lower parts of the left side of the vertical frame plate 4. The bottom of the upper support plate 13 is connected to a plug screw 15. The middle of the horizontal frame plate 1 is fixedly installed with a lower support plate 14. When assembling the cable rack of the present invention, the vertical frame plate 4 overlaps and is supported on the lower support plate 14 through the upper support plate 13. The plug screw 15 passes through the lower support plate 14 and can be fixed by a nut, thereby realizing the fixed connection between the vertical frame plate 4 and the horizontal frame plate 1. The structure is simple and reasonable, and the connection is convenient and quick, which can realize the rapid assembly of the cable rack on site and improve the work efficiency.

[0031] Furthermore, in one embodiment, such as Figure 2 As shown, guide plates 8 are fixedly installed on the upper and lower parts of the right side of the vertical frame plate 4. The main and auxiliary cable frame plate 3 is slidably connected to the guide plates 8. Through the slidable connection between the main and auxiliary cable frame plate 3 and the guide plates 8, the distance between the upper and lower main and auxiliary cable frame plates 3 can be adjusted as needed, thereby conveniently and quickly adjusting the ring size of the auxiliary cable frame for hanging auxiliary cables, which has strong adaptability.

[0032] Furthermore, in one embodiment, such as Figure 2 As shown, the main and slack cable rack 3 includes a hook seat 9 that is slidably connected to the guide hanging plate 8. A support arc plate 11 is fixedly connected to the right side of the hook seat 9, and a side baffle 10 is connected to the end of the support arc plate 11. The arc-shaped convex surface of the support arc plate 11 on the upper main and slack cable rack 3 faces upward, and the lower one faces downward. The arc-shaped convex surface on the support arc plate 11 can stably gather the slack cable, avoiding the wear and damage that traditional right-angle plates may cause to the slack cable. The side baffle 10 can cooperate with the guide hanging plate 8 on its left side to form a U-shaped groove to limit the slack cable and ensure its stability during the gathering process.

[0033] Furthermore, in one embodiment, such as Figure 2 , 3 As shown, the upper and lower parts of the vertical frame plate 4 are provided with multiple positioning holes 16 along the direction of the guide plate 8. The mounting base 9 is provided with positioning bolts 12, and the end of the positioning bolts 12 can be selectively inserted into the positioning holes 16. The position of the main and auxiliary cable frame plates 3 in the vertical direction can be adjusted by the positioning bolts 12, so as to adjust the distance between the upper and lower main and auxiliary cable frame plates 3, which is convenient and quick to operate.

[0034] Furthermore, in one embodiment, such as Figure 3 As shown, an adjusting sleeve 17 is slidably disposed on the cross frame plate 1, and the right end of the clamping half ring 18 is fixedly connected to the adjusting sleeve 17. The position of the clamping half ring 18 on the cross frame plate 1 can be adjusted by the adjusting sleeve 17, thereby adjusting the distance between the two clamping half rings 18 that make up one clamping ring 2, so as to fix the cable rack of the present invention to the pole. The adjusting sleeve 17 is provided with a locking bolt 19, which can be used to lock and fix the position of the clamping half ring 18, making the operation convenient and quick.

[0035] Furthermore, in one embodiment, such as Figure 5As shown, the fixed connector 6 includes a connecting sleeve plate 23 fixedly connected to the middle of the right side of the vertical frame plate 4. An extension plate 24 is fixedly provided on the side of the connecting sleeve plate 23, and the telescopic crossbar 5 is fixedly connected to the extension plate 24. The extension plate 24 is provided so that the side slack cable rack plate 7 and the main slack cable rack plate 3 are located in the same vertical plane, thereby ensuring stable collection of slack cables.

[0036] Furthermore, in one embodiment, such as Figure 5 As shown, the side cable support plate 7 includes a side support arc plate 26 fixedly connected to the end of the telescopic crossbar 5. Both the left and right ends of the side support arc plate 26 are connected to limiting straight plates 27. The arc-shaped convex surface of the side support arc plate 26 faces the end away from the telescopic crossbar 5, so that when the excess cable is collected, the excess cable can be supported and guided by the side support arc plate 26, while avoiding damage to the excess cable. The limiting straight plates 27 can limit the excess cable.

[0037] Furthermore, in one embodiment, such as Figure 4 As shown, a support base 22 is fixedly installed on the left side of the crossbeam 1, and a support pad 21 is installed on the support base 22. The support base 22 is located between the two clamping half rings 18. When the cable rack of the present invention is installed through the clamping half rings 18, the support base 22 and the support pad 21 installed on it can press against the pole to ensure the tightness and reliability of the connection between the clamping ring 2 and the pole.

[0038] Furthermore, in one embodiment, such as Figure 5 , 6 As shown, a fixing bolt 28 is threaded onto the left side of the connecting sleeve plate 23, and an adjustment knob 25 is provided on the telescopic crossbar 5. The fixing bolt 28 can be used to fix the fixing seat 6 to the vertical frame plate 4, and the adjustment knob 25 can be used to adjust the length of the telescopic crossbar 5 to adapt to the needs of collecting excess cable of different sizes and lengths. Assembly and damage are convenient and quick, and the operation efficiency is high.

[0039] In summary, the present invention provides a portable assembled medium-voltage power distribution line OPGW cable support, the main frame of which is composed of a clamping ring 2, a horizontal frame plate 1, and a vertical frame plate 4. The clamping ring 2 is composed of two clamping half-rings 18.

The left ends of the two clamping half-rings 18 can be connected by a long screw connecting pair 20, thereby fixing the cable support of the present invention to the pole. A horizontal frame plate 1 is connected to the upper and lower parts of the left side of the vertical frame plate 4. A clamping ring 2 is connected to each horizontal frame plate 1. The upper and lower clamping rings 2 cooperate to stably connect the vertical frame plate 4 to the pole, so as to ensure the stability of the cable support and collection of the cable in this invention. A main cable support plate 3 is slidably connected to the upper and lower parts of the right side of the vertical frame plate 4. It is used to support and collect the excess cable from the upper and lower directions. A telescopic crossbar 5 is connected to the right side of the vertical frame plate 4 through a fixed connector 6 fixed in the middle. The end of the telescopic crossbar 5 is connected to a side cable support plate 7. It is used to guide, limit and collect the excess cable from the left and right directions.
