Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, and in particular to a modular power distribution cabinet. Background Technology

[0002] A modular distribution cabinet is a power distribution device that integrates multiple power distribution components or modules. Its core feature is the integration of multiple power distribution units into a unified structure, facilitating installation, operation, and maintenance. This distribution cabinet mainly consists of a cabinet body, mounting plates, doors, and cable management systems. The interior of the cabinet is divided into different installation areas, such as a first installation area and a second installation area, to accommodate the installation needs of different types of power distribution equipment. The mounting plates are designed to be installed on guide rails, facilitating the disassembly, maintenance, and installation of electrical components within the power distribution equipment. The doors are connected to the cabinet body via hinges, allowing for free opening and closing, facilitating the operation and inspection of the equipment inside. The cable management system is responsible for the neat arrangement and storage of cables, improving wiring efficiency.

[0003] Modular distribution cabinets significantly save installation space by integrating multiple power distribution components or modules into a compact, unified structure. The cabinet's internal modular design allows for free combination and replacement of modules, providing users with flexible configuration options to meet specific needs. Thanks to this modular design, maintenance of modular distribution cabinets is simplified. When a module fails, only that module needs to be replaced, eliminating the need for disassembly and repair of the entire distribution cabinet. The cable routing system ensures orderly cable arrangement, preventing cable tangling and crossing, thereby improving wiring efficiency and safety.

[0004] In practical applications, modular design is widely used in combined distribution cabinets to install electrical components such as switches. This design strategy enhances the flexibility and scalability of the distribution cabinet to a certain extent, facilitating maintenance and upgrades. However, the structural complexity of the modular design increases the difficulty of manufacturing and assembly. The connection and cooperation between modules require high precision to ensure the stability and safety of the distribution cabinet, which increases production costs and time consumption to some extent.

[0005] Furthermore, modular design may result in an excessive number of modules and structural components, which could adversely affect the heat dissipation performance inside the distribution cabinet. Electrical equipment generates heat during operation; insufficient heat dissipation can lead to overheating, affecting its performance and lifespan, and potentially even posing safety risks. Therefore, while ensuring structural stability, modular design must fully consider heat dissipation. Utility Model Content

[0006] The main objective of this invention is to provide a modular power distribution cabinet that can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A modular power distribution cabinet includes a cabinet body, a cabinet door, and a switch assembly, wherein the cabinet door is connected to the cabinet body via a hinge assembly;

[0009] The inner end face of the cabinet is connected to an isolation combination frame via a heightening bracket. Multiple combination mounting frames are installed between two isolation combination frames. Switch components are connected to the multiple combination mounting frames by bolts. Multiple combination holes are provided on the combination mounting frames and isolation combination frames. Bolts are inserted into the combination holes to fix the combination mounting frames and isolation combination frames, and the position can be adjusted by sliding up and down along the combination mounting frames to adapt to switch components of different specifications.

[0010] The bottom of the two isolation combination frames is connected to a rotating frame, and the rotating frame has a docking hole.

[0012] In a further optional embodiment, the cross-section of the modular mounting frame is designed in the shape of an "Ω" and multiple round holes are provided on the modular mounting frame. The modular mounting frame can move up and down along the isolation frame to adjust its position. Anti-slip pads are provided at the connection between the modular mounting frame and the isolation frame.

[0013] In a further alternative, the rotating frame has a U-shaped cross-section, with the arc surface of the rotating frame facing the end face of the isolation assembly frame. Multiple docking holes are distributed in a ring on the rotating frame. Anti-slip strips are provided at the connection between the rotating frame and the isolation assembly frame. The connection between the rotating frame and the isolation assembly frame is achieved by bolts passing through the assembly holes and docking holes.

[0014] In a further alternative, multiple mounting frames are fixed to the rotating frame by bolts, and anti-slip pads are provided at the connection between the mounting frame and the rotating frame. The cooling fan is positioned directly opposite the round hole on the mounting frame for airflow from the cooling fan, and the angle of the cooling fan is adjusted via the rotating frame.

The fastening bolt passes through the opening in the cooling fan and the mounting frame, and is fitted with a fastening nut and an anti-slip washer to connect the two. The filter screen is fixed to the cooling fan by bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The modular mounting bracket and isolation bracket are fixed by combination holes and bolts, and can slide up and down along the isolation bracket to adjust their position, thereby adapting to different specifications of switch components and improving the flexibility and adaptability of the distribution cabinet.

[0018] The cooling fan is connected via a mounting frame and a rotating bracket, allowing its angle to be adjusted to meet different cooling needs. Simultaneously, the cooling fan draws in air, filters out impurities through a filter, and expels hot air from the cabinet, effectively improving heat dissipation and ensuring the normal operation of the equipment inside the distribution cabinet.

[0019] The modular support system is bolted together, with anti-slip pads and strips at the joints to enhance stability and reliability. The cooling fan is secured to the mounting frame with fasteners, similarly ensuring stability and reliability. This design makes the distribution cabinet more stable and reliable during use, extending its service life. The bolted connections between components allow for easy disassembly and replacement of parts such as cooling fans and filters for cleaning and maintenance. This design reduces maintenance costs and improves equipment maintenance efficiency. Attached Figure Description

[0029] The isolation unit 4 has a "T"-shaped cross-section, with multiple equidistant combination holes 5. These holes 5 can be either oblong or round. The extension frame 6 has screw holes, and bolts are used to connect it to the isolation unit 4. Anti-slip pads are provided at the connection point between the extension frame 6 and the isolation unit 4 to ensure a stable connection. The extension frame 6 is bolted to the cabinet 1 to enhance the overall structural stability.

[0030] The modular mounting bracket 7 has an "Ω" shaped cross-section and multiple circular holes. It moves up and down along the isolating assembly 4 to adjust its position to accommodate different sizes of switch components 3. Anti-slip pads are provided at the connection between the modular mounting bracket 7 and the isolating assembly 4 to prevent slippage during use.

[0031] The rotating frame 8 has a U-shaped cross-section. The arc surface of the rotating frame 8 faces the end face of the isolation combination frame 4. Multiple docking holes 9 are distributed in a ring on the rotating frame 8. Anti-slip strips are provided at the connection between the rotating frame 8 and the isolation combination frame 4. The rotating frame 8 and the isolation combination frame 4 are connected by bolts inserted into the combination hole 5 and the docking hole 9 to ensure the stability and reliability of the rotating frame 8.

[0032] Multiple mounting frames 10 are bolted to the rotating frame 8.
