This utility model overcomes the shortcomings of the prior art, has a reasonable design, and the clever use of the shelf helps improve work efficiency. It is also convenient for folding and storage, saves space, and has high social value and application prospects.

[0003] In the prior art, including the aforementioned patents, in power systems, distribution cabinets, as core hub equipment for power distribution and control, have their internal cables' scientific layout and efficient management directly affecting the stable operation and safe maintenance of the power system. Currently, traditional distribution cabinets have significant limitations in cable management: First, the built-in cable layer supports mostly adopt a fixed structure design, which still occupies a large amount of cabinet space when the equipment is idle or the number of cables is reduced, resulting in increased storage and transportation costs; Second, limited by fixed specifications, the supports are difficult to adapt to the differentiated installation needs of cables of different diameters and types, especially during power engineering renovation or expansion, where the spacing and number of layers cannot be flexibly adjusted, leading to frequent cable tangling; Third, the rigid support layout makes cable routing irregular, which not only increases the difficulty of daily inspections but also seriously hinders maintenance personnel from quickly locating fault points when equipment fails, significantly prolonging power outage maintenance time, and thus affecting the stability and reliability of regional power supply. Therefore, it is necessary to design a distribution cabinet with foldable cable layer supports to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a power distribution cabinet with a foldable cable layered bracket, so as to solve the problems mentioned in the background art, such as the inability to flexibly adjust the layered bracket, the poor heat dissipation effect of the power distribution cabinet, and the inconvenience of bracket adjustment and panel fixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet with a foldable cable layer support, comprising a cabinet body, a two-way cabinet door connected to the front of the cabinet body via hinges, a cabinet top installed on the top of the cabinet body, an angle steel frame installed on the inner wall of the cabinet body, an adjusting seat installed on the outer wall of the angle steel frame, a panel engaged with the inner side of the adjusting seat, a connecting plate engaged with the inside of the adjusting seat, a limit ring provided on the outside of the connecting plate, a foldable layer assembly suspended through the inside of the connecting plate, a cavity base installed at the bottom of the cabinet body, and a cooling fan installed on the top of the cavity base.

[0006] Furthermore, the interior of the folding and layering assembly includes a hook, a spring buckle, a folding rod, a support rod, and a separation clamp. The hook is suspended inside the connecting plate, a spring buckle is provided on one side of the hook, the bottom pivot of the hook is connected to the folding rod, the outer wall pivot of the hook is connected to the support rod, and one end of the support rod is fixedly connected to the separation clamp.

[0007] Furthermore, the folding rods are connected to the front and back sides of the hooks respectively via pivots, and the two sets of folding rods are movably connected to the support rods in a cross manner. The separation clamping block includes a base connected to the support rod, an arc-shaped groove provided on the surface of the base, and an elastic clamping piece that engages in the arc-shaped groove. The elastic clamping piece has a C-shaped structure.

[0008] Furthermore, the panel is provided in two sets, and is respectively installed on the front and back sides of the connecting plate.

[0009] Furthermore, the cabinet top is an arched top, and both the front and back eaves of the cabinet top are provided with heat dissipation holes, and the bottom of the cavity base is provided with another set of heat dissipation holes.

[0010] Furthermore, the adjusting seat includes a U-shaped slot fixedly connected to the angle steel frame, an adjusting bolt passing through the U-shaped slot, and anti-slip teeth set on the inner wall of the U-shaped slot. The connecting plate is clamped and fixed to the U-shaped slot by the adjusting bolt, and the anti-slip teeth are in frictional engagement with the surface of the connecting plate.

[0011] Furthermore, a protective cover is provided on the outside of the cooling fan. The protective cover includes an annular frame connected to the cavity base and arc-shaped guide vanes evenly distributed on the inner side of the annular frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the distribution cabinet with a foldable cable layer support is reasonable and has the following advantages:

[0013] (1) The modular combination design of the foldable layered bracket allows for free adjustment of the folding layered components at multiple angles. Users can flexibly adjust the layering height, tilt angle and unfolding width of the bracket according to the cable specifications, quantity and routing requirements. In the idle state, the bracket can be folded 180° along the folding axis, which is convenient for storage in the side compartment of the distribution cabinet, greatly saving storage space. The matching separation clamp is made of high-strength engineering plastic, with built-in anti-slip silicone pads and elastic fastening devices, which can achieve three-point ring fixation of cables with different outer diameters. There are interval slots between the clamps, which can physically separate cables of different voltage levels and functional types, so that the wiring inside the distribution cabinet presents a neat layout of horizontal and vertical lines, effectively avoiding cable entanglement and wear. Furthermore, the visualized line distribution shortens the troubleshooting time and significantly improves the efficiency of later maintenance.

[0014] (2) Through scientific structural design, the cabinet top and cavity base are equipped with high-speed cooling fans and detachable protective covers respectively. The two work together to form a vertical three-dimensional heat dissipation channel. The cooling fans adopt intelligent temperature control technology. When the temperature inside the cabinet reaches the preset threshold, they will automatically turn on and quickly dissipate the accumulated heat. Ventilation holes are evenly distributed on both sides of the cabinet top. While ensuring effective protection against foreign object intrusion, the system also minimizes wind resistance and improves air circulation efficiency. This high-efficiency heat dissipation system can keep the temperature inside the cabinet at the optimal working range of electrical components, significantly reducing the aging rate of components caused by high temperature. Actual tests have verified that it can extend the overall service life of the equipment and effectively ensure the stable operation and reliability of the distribution cabinet.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A power distribution cabinet with a foldable cable layer support includes a cabinet body 1. The front of the cabinet body 1 is connected to a two-way cabinet door 2 via a hinge. The top of the cabinet body 1 is equipped with a cabinet top 3. An angle steel frame 4 is installed on the inner wall of the cabinet body 1. An adjustment seat 5 is installed on the outer wall of the angle steel frame 4. A panel 6 is engaged with the inner side of the adjustment seat 5. A connecting plate 7 is engaged with the inside of the adjustment seat 5. A limit ring 8 is provided on the outside of the connecting plate 7. A foldable layer assembly 9 is suspended through the inside of the connecting plate 7. A cavity base 10 is installed at the bottom of the cabinet body 1. A cooling fan 11 is installed on the top of the cavity base 10.

[0025] The above structure features a bidirectional opening design that facilitates access to internal equipment and cables from both sides of the cabinet 1, greatly improving the convenience of inspection and maintenance. Both the front and back top eaves are equipped with heat dissipation holes. The arched structure not only helps rainwater slide off quickly, preventing water accumulation from corroding the cabinet 1, but also guides airflow, accelerating heat dissipation in conjunction with the heat dissipation holes. Angle steel frame 4 is installed on the inner wall of the cabinet 1 to provide stable support for subsequent components.

[0026] Furthermore, the interior of the folding layer assembly 9 includes a hook 901, a spring buckle 902, a folding rod 903, a support rod 904, and a separation clamp 905. The hook 901 is suspended inside the connecting plate 7. A spring buckle 902 is provided on one side of the hook 901. The bottom pivot of the hook 901 is connected to the folding rod 903. The outer wall pivot of the hook 901 is connected to the support rod 904. One end of the support rod 904 is fixedly connected to the separation clamp 905. The folding rod 903 is connected to the front and back of the hook 901 through the pivot, and the two sets of folding rods 903 are movably connected to the support rod 904 in a cross manner. The separation clamp 905 includes a base connected to the support rod 904, an arc-shaped groove provided on the surface of the base, and an elastic clamp piece that engages in the arc-shaped groove. The elastic clamp piece has a C-shaped structure.

[0027] The above structure is suspended inside the connecting plate 7 by hook 901 and spring buckle 902. Spring buckle 902 can realize quick installation and removal of hook 901. The bottom and outer wall of hook 901 are connected to folding rod 903 and support rod 904 respectively by pivot. The two sets of folding rods 903 are movably connected to support rod 904. The bracket can be flexibly unfolded or folded according to the number and specifications of cables. The separation clamp 905 at one end of support rod 904 has an arc-shaped groove on its base surface. C-type elastic clips are engaged in the arc-shaped groove to firmly clamp the cable and prevent the cable from shaking and tangling.

[0028] Furthermore, the panel 6 is provided in two sets, which are respectively installed on the front and back sides of the connecting plate 7. The cabinet top 3 is an arched top, and both the front and back eaves of the cabinet top 3 are provided with heat dissipation holes. The bottom of the cavity base 10 is provided with another set of heat dissipation holes.

[0029] The above structure has a cavity base 10 installed at the bottom of the cabinet 1 and a cooling fan 11 installed at the top. A protective cover consisting of an annular frame and arc-shaped guide vanes is set on the outside of the cooling fan 11. The annular frame is connected to the cavity base 10, and the arc-shaped guide vanes are evenly distributed on the inner side of the annular frame. This can guide the airflow direction, improve the heat dissipation efficiency, and at the same time block debris from entering, protecting the cooling fan 11 for normal operation.

[0030] Working principle: First, fix the angle steel frame 4 to the inner wall of the cabinet 1 according to the designed position, ensuring it is horizontal and vertical. Tighten the bolts to ensure a firm connection. Align the U-shaped slot 501 of the adjusting seat 5 with the angle steel frame 4 and initially fix it using the adjusting bolt 502. Adjust the height of the adjusting seat 5 on the angle steel frame 4 according to actual needs. After adjustment, tighten the adjusting bolt 502 to ensure the anti-slip teeth 503 tightly engage with the angle steel frame 4, ensuring the connecting plate 7 is accurately and stably positioned. Then, attach the two sets of panels 6 to the front and back of the connecting plate 7 respectively, and check the engagement. Check if it is tight, open the spring buckle 902, hang the hook 901 of the folding layer component 9 in a suitable position inside the connecting plate 7, close the spring buckle 902 to fix the hook 901, adjust the angle of the folding rod 903 and the support rod 904 according to the cable layering requirements, unfold the layering bracket, install the cooling fan 11 on the top of the cavity base 10, connect the power cord, and then fix the ring frame of the protective cover to the cavity base 10, ensuring that the arc-shaped guide plate is in the correct direction, install the cabinet top 3 on the top of the cabinet 1, fix it with bolts, and check whether the heat dissipation holes of the cabinet top 3 are unobstructed;

[0031] Next, open the two-way cabinet door 2 and plan the layered layout according to the cable type and function. Pass the cables through the C-shaped elastic clips of the separation clamp 905 in sequence. The elastic deformation of the elastic clips will firmly clamp the cables in the arc-shaped groove, so that the cables are neatly arranged in layers and avoid tangling and mutual interference.

[0032] Finally, after the distribution cabinet is put into use, the cooling fan 11 starts automatically, drawing hot air from the bottom of the cavity base 10 into the cabinet through the heat dissipation holes. After being accelerated by the cooling fan 11, the hot air is guided by the arc-shaped guide vanes of the protective cover and discharged from the heat dissipation holes on the top of the cabinet 3, forming air convection, continuously carrying away the heat inside the cabinet and maintaining a stable internal temperature.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
