Description

Technical Field

[0001] This utility model relates to the field of municipal low-voltage engineering, and in particular to a layered cable management rack for municipal low-voltage wells. Background Technology

[0002] In municipal low-voltage electrical engineering, low-voltage wells serve as crucial aggregation and distribution nodes for various communication, signal, and control cables. The arrangement and management of cables within these wells directly impact system stability, maintenance efficiency, and security. With the rapid development of urban informatization, the types and quantities of cables requiring installation in low-voltage wells are increasing daily, including but not limited to fiber optic cables, coaxial cables, and twisted-pair cables. These cables, while transmitting different signals, also place higher demands on their arrangement, fixing, and labeling.

[0003] In existing technologies, traditional methods of cable management in low-voltage wiring shafts often involve simple bundling and securing with cable ties or cable trays. While this method is inexpensive, it has several drawbacks in practical applications. First, the lack of effective layering and isolation between cables easily leads to tangling and crossing, affecting aesthetics and increasing the difficulty of later maintenance and troubleshooting. Second, when adding, removing, or replacing cables, traditional methods often require untying numerous cable ties or dismantling parts of the cable trays, which is cumbersome and can easily damage the cables. Furthermore, as the number of cables increases, the internal space of the low-voltage wiring shaft becomes increasingly congested, and traditional management methods struggle to meet the effective heat dissipation and ventilation requirements of the cables, further impacting cable lifespan and system stability.

[0004] Therefore, there is an urgent need for a cable management rack that can fix cables in municipal low-voltage wells in layers, facilitate management and maintenance, and has good heat dissipation performance. This has become a technical problem that needs to be solved in the field of municipal low-voltage engineering. Utility Model Content

[0005] The main purpose of this utility model is to provide a layered cable management rack for municipal low-voltage wells, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A municipal low-voltage electrical well cable layer fixing and management rack includes a vertical mounting frame. One side of the vertical mounting frame is provided with several cable fixing mechanisms. Each cable fixing mechanism includes a horizontal support frame, a fixed clamp, a screw, an L-shaped adjusting plate, and a movable clamp. The horizontal support frame is fixedly connected to the vertical mounting frame by U-bolts and nuts. Several fixed clamps are fixedly connected to the top surface of the horizontal support frame. The screw is movably connected to the inside of the horizontal support frame and located below the fixed clamps through rotating rods at its upper and lower ends. The movable clamp is movably connected to the screw through an L-shaped adjusting plate on the side wall.

[0007] In a further preferred embodiment of this invention, a set of symmetrical mounting blocks are fixedly installed on each of the two side walls of the vertical mounting frame, and mounting holes are provided on the side walls of the mounting blocks.

[0008] In a further preferred embodiment of this invention, several adjustment holes are provided on both sides of the vertical mounting bracket in a vertical array.

[0009] In a further preferred embodiment of this invention, a set of symmetrical positioning plates is fixedly installed at the left end of the transverse support frame, and a set of symmetrical connecting holes are provided on the side wall of the positioning plates.

[0010] In a further preferred embodiment of this invention, the two ends of the U-bolt are respectively inserted into the adjustment hole and pass through the connection hole, and the nut is threadedly connected to the U-bolt.

[0011] In a further preferred embodiment of this invention, the outer wall of the transverse support frame is provided with several sets of rotating holes arranged in a transverse array, presenting a vertically symmetrical arrangement, and the top surface of the transverse support frame is also provided with a strip-shaped opening on one side of the rotating holes.

[0012] In a further preferred embodiment of this invention, the top surface of the transverse support frame is fixedly equipped with several fixed clamps in a transverse array, and the fixed clamps are located above the rotating holes. The upper and lower ends of the screw are respectively fixedly equipped with rotating rods, and the rotating rods are movably installed in the rotating holes. A knob is also fixedly installed at the bottom end of the lower rotating rod. The top surface of the transverse part of the L-shaped adjusting plate is provided with a screw hole, and the L-shaped adjusting plate is threadedly connected to the screw through the screw hole. The vertical part of the L-shaped adjusting plate is inserted into the strip-shaped opening, and a movable clamp is also fixedly installed on the side wall of the vertical part of the L-shaped adjusting plate. The movable clamp is located directly above the fixed clamp, and arc-shaped grooves are respectively provided on the opposite walls of the movable clamp and the fixed clamp.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the cable management rack utilizes multiple cable fixing mechanisms on a vertical mounting frame. Each mechanism includes a fixed clamp and an adjustable movable clamp, enabling layered cable fixing. This layered design not only makes the cables more neat and orderly, avoiding the problems of cable tangling and crossing in traditional methods, but also greatly improves the efficiency of later maintenance and troubleshooting. Maintenance personnel can quickly locate specific cables, reducing misoperation and troubleshooting time caused by cable disorder, thereby enhancing the stability and reliability of the entire low-voltage system. The horizontal support frame is fixedly connected to the vertical mounting frame via U-bolts and nuts, and the vertical mounting frame has multiple adjustment holes. This design allows the height of the horizontal support frame to be flexibly adjusted according to actual needs, adapting to different cable laying requirements and the spatial layout inside the low-voltage well. Meanwhile, the movable clamp is connected to the fixed clamp via a screw and an L-shaped adjustment plate. Rotating the screw allows for easy adjustment of the distance between the movable and fixed clamps to accommodate cables of different diameters. This adjustability not only enhances the adaptability of the equipment but also allows the cable management rack to adapt to future changes, such as the addition, removal, or replacement of cables, without requiring large-scale modifications to the entire cable management rack. When it is necessary to add, remove or replace cables, simply adjust the position of the movable clamp by rotating the screw to easily fix and release the cables. Compared with the traditional method of untying a large number of cable ties or removing part of the cable tray, this operation method greatly simplifies the operation process and reduces the risk of cable damage during operation. At the same time, due to the ease of operation, maintenance personnel can complete the addition, removal or replacement of cables more quickly, thereby reducing maintenance costs and time costs. Finally, the layered fixing method not only makes the cables neatly arranged, but also optimizes the space utilization inside the low-voltage well. By rationally arranging the cable fixing mechanism, the vertical and horizontal space of the low-voltage well can be fully utilized, reducing the crowding and overlap between cables. This space optimization helps improve the heat dissipation and ventilation of the cables, avoiding overheating problems caused by dense cables, thereby extending the service life of the cables and improving the stability of the system.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 - Figure 5 As shown, a municipal low-voltage cable layer fixing and management rack includes a vertical mounting frame 1. A plurality of cable fixing mechanisms 2 are provided on one side of the vertical mounting frame 1. The cable fixing mechanism 2 includes a horizontal support frame 6, a fixing clamp 11, a screw 15, an L-shaped adjusting plate 18, and a movable clamp 20. The horizontal support frame 6 is fixedly connected to the vertical mounting frame 1 by U-bolts 9 and nuts 10. A plurality of fixing clamps 11 are fixedly connected to the top surface of the horizontal support frame 6. The screw 15 is movably connected to the inside of the horizontal support frame 6 and located below the fixing clamps 11 by rotating rods 16 at the upper and lower ends. The movable clamp 20 is movably connected to the screw 15 by the L-shaped adjusting plate 18 on the side wall.

[0018] like Figure 2 As shown, a set of symmetrical mounting blocks 3 are fixedly installed on both sides of the vertical mounting frame 1, and mounting holes 4 are opened on the side walls of the mounting blocks 3. The vertical mounting frame 1 can be installed and fixed in the weak current well through the mounting holes 4 opened on the mounting blocks 3 and with the use of bolts. Several adjustment holes 5 are also provided on the two side walls of the vertical mounting frame 1 in a vertical array. The adjustment holes 5 provide the possibility of adjusting the height of the horizontal support frame 6. By selecting the adjustment holes 5 at different positions for installation, the height of the horizontal support frame 6 can be flexibly adjusted to adapt to the different cable laying requirements and the spatial layout inside the weak current well, thereby enhancing the adaptability and flexibility of the cable management frame. A set of symmetrical positioning plates 7 are fixedly installed on the left end of the transverse support frame 6, and a set of symmetrical connecting holes 8 are opened on the side wall of the positioning plate 7. The connecting holes 8 on the positioning plate 7 are used to cooperate with the transverse support frame 6 to achieve installation and fixation. The two ends of the U-bolt 9 are respectively inserted into the adjustment hole 5 and pass through the connection hole 8, and the nut 10 is threaded together with the U-bolt 9, so that several horizontal support frames 6 can be fixed on the vertical mounting frame 1 in a layered manner. Several sets of rotating holes 13 arranged in a horizontal array are provided on the outer wall of the horizontal support frame 6. A strip-shaped opening 14 is also provided on the top surface of the horizontal support frame 6 and on one side of the rotating holes 13. The rotating holes 13 provide support for the rotation of the screw 15, while the strip-shaped opening 14 provides space for the vertical part of the L-shaped adjustment plate 18 to pass through. Several fixed clamps 11 are fixedly installed on the top surface of the horizontal support frame 6 in a horizontal array, and the fixed clamps 11 are located above the rotating holes 13. Rotating rods 16 are fixedly installed at the upper and lower ends of the screw 15, and the rotating rods 16 are movably installed within the rotating holes 13. A knob 17 is also fixedly installed at the bottom end of the lower rotating rod 16. A screw hole 19 is opened on the top surface of the horizontal part of the L-shaped adjusting plate 18, and the L-shaped adjusting plate 18 is threadedly connected to the screw 15 through the screw hole 19. The vertical part of the L-shaped adjusting plate 18 is inserted into the strip-shaped opening 14, and a movable clamp 20 is fixedly installed on the side wall of the vertical part of the L-shaped adjusting plate 18. The movable clamp 20 is located directly above the fixed clamp 11, and arc-shaped cable grooves 12 are respectively provided on the opposite walls of the movable clamp 20 and the fixed clamp 11. Rotating the knob 17 can drive the screw 15 to rotate through the rotating rod 16, thereby driving the L-shaped adjusting plate 18 to move up and down along the screw 15 through the screw hole 19, and simultaneously driving the movable clamp 20 to move up and down, so as to move closer to or away from the fixed clamp 11 to fix and release the cable. The design of the arc-shaped cable groove 12 ensures the stable fixation of the cable and avoids the cable from sliding and falling off. This design is not only easy to operate, but also can adapt to cables of different diameters, improving the versatility and practicality of the cable management rack.

[0019] The specific operating principle of this municipal low-voltage cable management rack is as follows: First, using the mounting blocks 3 and mounting holes 4 on both sides of the vertical mounting frame 1, bolts are used to securely install the vertical mounting frame 1 in a suitable position inside the low-voltage well, thus building a basic framework for subsequent cable fixing. Subsequently, based on the cable layout in the low-voltage well and the actual laying requirements, the adjustment hole 5 at the corresponding height of the side wall of the vertical mounting frame 1 is selected. The two ends of the U-bolt 9 are passed through the connection hole 8 and adjustment hole 5 on the positioning plate 7 of the horizontal support frame 6 in sequence, and then the nut 10 is tightened. In this way, multiple horizontal support frames 6 can be stably installed on the vertical mounting frame 1 in a layered manner, thus completing the construction of the layered structure of the cable management frame. When it is necessary to fix the cable, place the cable in the arc-shaped groove 12 of the fixed clamp 11 on the top surface of the horizontal support frame 6. By rotating the knob 17 at the lower end of the screw 15, the knob 17 drives the rotating rod 16 to rotate in the rotating hole 13 of the horizontal support frame 6, thereby driving the screw 15 to rotate. Since the L-shaped adjusting plate 18 is threadedly connected to the screw 15 through the screw hole 19 and its vertical part is inserted into the strip opening 14, the rotation of the screw 15 will cause the L-shaped adjusting plate 18 to move up and down along the screw 15, and simultaneously drive the movable clamp 20 fixed on the side wall of the vertical part of the L-shaped adjusting plate 18 to move closer to the fixed clamp 11. As the movable clamp 20 gradually moves closer, it and the arc-shaped groove 12 on the opposite side wall of the fixed clamp 11 together tightly clamp the cable. The curved surface design of the arc-shaped groove 12 can fit the outer surface of the cable, provide uniform pressure, prevent the cable from sliding and falling off, and achieve stable fixing of cables of different diameters. During later cable maintenance or replacement, simply rotate knob 17 in the opposite direction to move movable clamp 20 away from fixed clamp 11 to easily release the cable for inspection, replacement, or addition. Through the layered cable fixing mechanism 2, staff can clearly distinguish different types and functions of cables and quickly locate the target cable, greatly shortening the time for troubleshooting and repair. When adding cables, the appropriate layer of horizontal support frame 6 can be flexibly selected for fixing according to the cable route and needs, without disrupting the original cable layout. This effectively avoids the inconvenience and damage risks caused by cable tangling in traditional cable management methods. At the same time, layered fixing ensures that the cables in the low-voltage well are distributed in an orderly manner, optimizes space utilization, improves ventilation and heat dissipation, extends the service life of the cables, and ensures the stable operation of the municipal low-voltage system.
