Description

Technical Field

[0001] This utility model relates to a cable outlet structure based on power distribution equipment, and belongs to the field of cables. Background Technology

[0002] In power systems, power distribution equipment is a key link in the distribution and transmission of electrical energy, and the cable outgoing structure, as an important connection between power distribution equipment and cables, has its stability and reliability directly related to the operational safety of the entire power system.

[0003] Cable outgoing structures often suffer from problems such as limited fixing methods, easy cable loosening, and inconvenient maintenance, especially in complex and variable operating environments. Furthermore, most cable outgoing structures use simple bolt fixing or cable ties, which are not only ineffective and prone to loosening due to vibration or external forces, but also require complete disassembly for cable replacement or repair, increasing maintenance difficulty and costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a cable outlet structure based on power distribution equipment, which has the advantages of stable and reliable structure and easy maintenance.

[0007] To achieve the above-mentioned structural stability, reliability, and ease of maintenance, this utility model provides the following technical solution: a cable outlet structure based on power distribution equipment, including a power distribution cabinet, a mounting frame, and a retaining frame. The top of the power distribution cabinet is provided with an installation opening adapted to the mounting frame. The retaining frame is fixedly connected to the upper surface of the mounting frame, and support plates are fixedly connected to both the left and right side walls of the retaining frame. The inner side of the mounting frame is provided with a fixing component for fixing cables.

[0022] 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.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a cable outlet structure based on power distribution equipment, including a power distribution cabinet 1, a mounting frame 2 and a baffle 3. The top of the power distribution cabinet 1 is provided with an installation opening that is compatible with the mounting frame 2. The baffle 3 is fixedly connected to the upper surface of the mounting frame 2, and the left and right side walls of the baffle 3 are both fixedly connected with support plates 4. The inner side of the mounting frame 2 is provided with fixing components for fixing cables.

[0024] like Figure 1 As shown, the fixing assembly includes a connecting frame 5 fixedly connected to the inner side of the mounting bracket 2, a cable sleeve 6 fixedly connected to the inner side of the connecting frame 5, threaded sleeves 7 fixedly connected to the left and right sides of the connecting frame 5 respectively, a threaded shaft 8 threadedly connected to the inner side of the threaded sleeve 7, a reinforcing plate 9 rotatably connected to the opposite ends of the threaded shafts 8 on the left and right sides respectively, and an elastic telescopic member 10 fixedly connected to the opposite side wall of the reinforcing plates 9 on the left and right sides respectively.

[0025] It should be noted that there are five connecting frames 5. The five connecting frames 5 are arranged equidistantly along the left and right directions of the mounting frame 2. The connecting frames 5 are made of high-strength aluminum alloy and the surface is anodized, which has excellent corrosion resistance and mechanical strength. The equidistant arrangement of the five connecting frames 5 ensures the uniform distribution of the cable and avoids stress concentration caused by uneven spacing. The left and right side walls of the connecting frames 5 are provided with connecting holes, and the threaded sleeves 7 are fixedly connected to the inner side of the corresponding connecting holes.

[0026] The top and bottom of the connecting frame 5 are provided with through holes, and the through holes on the top and bottom sides are connected to the corresponding cable sleeves 6. The top and bottom of the mounting bracket 2 are provided with extension holes, and the extension hole at the top is connected to the baffle 3, and the extension hole at the bottom is connected to the through hole at the bottom of the corresponding connecting frame 5.

[0027] The right side wall of the left reinforcing plate 9 is in close contact with the left side wall of the corresponding cable sleeve 6, and the left side wall of the right reinforcing plate 9 is in close contact with the right side wall of the corresponding cable sleeve 6. The reinforcing plate 9 is made of highly elastic polyurethane material and has anti-slip texture on the surface to ensure maximum friction between the contact surface and the cable sleeve 6. The close contact design can effectively prevent the cable from shifting due to vibration or external force during operation.

[0028] The left end of the left elastic expansion member 10 is fixedly connected to the inner left side wall of the corresponding connecting frame 5, and the right end of the right elastic expansion member 10 is fixedly connected to the inner right side wall of the corresponding connecting frame 5. There are two elastic expansion members 10 on both sides, and the two elastic expansion members 10 on the same side are arranged sequentially along the vertical direction of the connecting frame 5. The elastic expansion member 10 adopts a combination structure of stainless steel spring and rubber buffer pad, which has excellent fatigue resistance and damping characteristics. The vertically arranged double elastic expansion members 10 can evenly distribute the radial pressure of the cable.

[0029] Pre-drilled holes are provided on the inner side of the left and right support plates 4. Bolt slots are provided on the left and right sides of the top of the distribution cabinet 1, and the bolt slots are connected to the corresponding pre-drilled holes. The fit between the pre-drilled holes and the bolt slots is made with high-precision machining technology to ensure alignment during installation.

[0030] In addition, the baffle 3 can prevent water dripping from the top from seeping into the interior of the distribution cabinet 1.

[0031] The working principle of the above embodiments is as follows:

[0032] The cable is introduced through the extension hole at the top of the distribution cabinet 1, extends downward through the cable sleeve 6, and finally exits from the extension hole at the bottom, forming a complete cable channel. By rotating the threaded shaft 8, the reinforcing plate 9 is pushed towards the cable sleeve 6 until the reinforcing plate 9 is in close contact with the cable sleeve 6. At the same time, the elastic telescopic member 10 provides reverse support force during the movement of the reinforcing plate 9 to ensure that the cable is evenly clamped. After the cable is fixed, the elastic telescopic member 10 continuously provides radial pressure to counteract the influence of external vibration or tension on the cable. When a cable needs to be replaced, simply rotate the threaded shaft 8 of the corresponding connecting frame 5 to disengage the reinforcing plate 9 from the cable sleeve 6, and the damaged cable can be pulled out of the cable sleeve 6 without the need for complete disassembly.
