The cable fixing bracket 31 can slide along the extension direction of the second transverse frame 3. When there are many cables laid, the position of the cable fixing bracket 31 can be adjusted to realize the distance adjustment of adjacent cable groups, which facilitates cable laying and maintenance.

[0026] In this embodiment, the first transverse frame 22 and the second transverse frame 3 are arranged opposite to each other. This embodiment also includes a third transverse frame 6, which is connected to the first transverse frame 22 and the second transverse frame 3 at both ends respectively. There are two third transverse frames 6 arranged opposite to each other. The first transverse frame 22, the second transverse frame 3, and the third transverse frame 6 are connected to form a closed frame. The first transverse frame 22, the second transverse frame 3, the third transverse frame 6, and the longitudinal frame 1 can all be made of angle steel or channel steel. By welding the frame to the longitudinal frame 1, a support frame for the cable shaft is formed, which has strong structural strength and is safe and reliable.

[0027] In this embodiment, the enclosure panel assembly 4 forming the wall of the cable installation shaft a includes a back panel 41 and side panels 42. The back panel 41 is positioned opposite to the door panel 5. In this embodiment, at least the side panels 42 are provided with fireproof partitions.

[0028] Preferably, the side plate 42 is provided with a ventilation opening 421, which extends downwards from the inside to the outside of the cable installation shaft a. This allows for natural ventilation to reduce the temperature inside the cable installation shaft a. Simultaneously, the downward-facing opening of the ventilation opening 421 prevents dust from falling into the cable installation shaft a. Furthermore, the cable shaft in this embodiment has a temperature regulation function. A temperature sensor (not shown in the figure) and a fan (not shown in the figure) are installed inside the cable installation shaft a, both of which are connected to a control module. The fan is installed at the bottom of the cable installation shaft a. When the temperature inside the cable installation shaft a exceeds the standard, the bottom fan can be automatically activated to enhance ventilation and heat dissipation inside the cable installation shaft a. Additionally, a smoke detector can be installed inside the cable installation shaft a as needed to automatically trigger an alarm in the event of a fire inside the cable installation shaft a.

[0029] In this embodiment, at least two door panels 5 are provided in each doorway b, which are slidably arranged along the second transverse frame 3. The second transverse frame 3 is provided with guide rails corresponding to the door panels 5. The guide rails are arranged along the second transverse frame 3, and the door panels 5 can slide along the guide rails on the second transverse frame 3. The opening and closing of the door panels 5 does not occupy the space outside the well. Moreover, by sliding different door panels 5, the condition of each part of the cable installation well a can be clearly observed in the doorway b, which is convenient for operation and maintenance.

[0030] In this embodiment, the first transverse frame 22 and the second transverse frame 3 are arranged opposite to each other. The cable fixing bracket 31 extends from the second transverse frame 3 to the first transverse frame 22. The cable fixing bracket 31 is provided with a plurality of mounting holes 313 for cable tie fixing. The cable is fixed to the cable fixing bracket 31 by cable ties passing through the fixing holes.

[0031] Cable fixing brackets 31 are arranged along the extension direction of the second transverse frame 3, and cable receiving grooves are formed between adjacent cable fixing brackets 31. Each cable is grouped and installed into its respective cable receiving groove for convenient operation and maintenance. In this embodiment, the second transverse frame 3 is preferably channel steel, and preferably, a first sliding groove 32 is provided in the extension direction of the second transverse frame 3. The width of the first sliding groove 32 is adapted to the height of the cable fixing bracket 31. This allows the cable fixing bracket 31 to slide on the second transverse frame 3. By sliding the cable fixing bracket 31 on the second transverse frame 3, the width of the cable receiving groove can be changed, facilitating both cable laying and adjusting the operating space of the cable receiving groove during maintenance. The cable fixing bracket 31 can also be made of angle steel with an L-shaped cross-section. Specifically, the cable fixing bracket 31 includes a first wing plate 311 and a second wing plate 312, with the first wing plate 311 vertically arranged and the second wing plate 312 horizontally arranged. The top of the second transverse frame 3 preferably has a second sliding groove 33 in the extending direction. A locking component that abuts against the top surface of the second wing plate 312 passes through the second sliding groove 33. The locking component can slide along the second sliding groove 33 and abut against the third transverse frame 3 and the second wing plate 312. The locking component includes a threaded sliding rod 34 and a locking nut 35 threadedly connected to the sliding rod 34. The sliding rod 34 has a sliding wall adapted to the second sliding groove 33. At least one of the first wing plate 311 and the second wing plate 312 is provided with a mounting hole 313. Depending on the length of the cable fixing bracket 31 and the number of mounting holes 313 provided thereon, as well as the width of the cable receiving groove, multiple sets of cables can be installed in each cable receiving groove. When each set of cables passes through the cable receiving groove of each frame frame, the cable is secured against the first wing plate 311 with cable ties. The opening of the cable receiving groove is opposite to the door opening b. Opening the door plate 5 exposes each cable receiving groove, making it easier for operation and maintenance personnel to inspect and repair.

[0032] The end of the cable fixing bracket 31 opposite to the door opening b is provided with a preset distance from the door panel 5, and the end of the cable fixing bracket 31 opposite to the door opening b is provided with an elastic sleeve to avoid large collisions between maintenance personnel and the end of the cable fixing bracket 31 after the door panel 5 is opened.

[0033] In this embodiment, the cable shaft can be manufactured into several shaft modules of height L, taking into account the height of the equipment room. These modules are transported to the site and then assembled using bolts, achieving flexibility in both manufacturing and on-site assembly. This prefabricated cable shaft features a large opening (b) with the cable fixing bracket 31 positioned opposite it. It also allows for easy, layered opening of the cable installation shaft (a). The door panel 5 does not occupy external space, reducing the difficulty of cable laying and facilitating subsequent maintenance.

[0034] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
