Technical Field

[0001] This utility model belongs to the field of power distribution technology, and in particular relates to a multifunctional power distribution box enclosure. Background Technology

[0002] Existing distribution box cables typically use bottom or side-bottom entry / exit methods. However, when the transformer is located above the distribution box, this method is inconvenient for installation and results in messy cables, also compromising safety. Furthermore, traditional distribution boxes require hoisting upon arrival at the site, which is inconvenient due to the lack of lifting lugs. Additionally, the absence of a support frame necessitates reliance on pallets during forklift transport, and the lack of mounting points for maintenance ladders during on-site repairs further complicates matters.

[0003] Conventional distribution boxes are usually made of metal, which is conductive, increasing the risk of electric shock and leakage. They are also heavy, making them inconvenient to transport and install.

[0004] In response to the technical problems existing in the above-mentioned prior art, those skilled in the art need to continuously develop a new type of distribution box enclosure. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a multifunctional distribution box enclosure. Its purpose is to achieve both safety and aesthetics in the distribution box's cable entry and exit, facilitate easy hoisting, allow forklift transport without relying on pallets, and make on-site maintenance more convenient by connecting a maintenance ladder.

[0006] The technical solution adopted by this utility model to achieve the above objectives is as follows: A multifunctional distribution box enclosure includes a distribution box with a cable compartment connected to its side. The cable compartment consists of an upper cover, a bottom plate, a front cover, a rear cover, and an outer cover. The outer cover is located on the side away from the distribution box and has a first ventilation opening. The interior of the cable compartment has a second ventilation opening and a channel on the connection surface with the distribution box body. The upper cover and bottom plate of the cable compartment have upper and lower cable entry / exit channels, respectively. A tower plug is connected above the upper cable entry / exit channel. A hanging bracket is fixedly connected to the top of the distribution box body, and a lifting lug is fixedly connected to the upper part of the hanging bracket. A ladder bracket is fixedly connected to the bottom of the distribution box.

[0007] Furthermore, the distribution box and the cable compartment are connected by bolts. Pre-embedded bolt holes are provided at fixed positions on the connection surface of the distribution box and the cable compartment. Reinforcing mounting bosses are provided at corresponding positions on the front and rear covers of the cable compartment. The connection surface of the distribution box is fixedly connected to the front and rear covers of the cable compartment by bolts. The upper and bottom covers of the cable compartment are fixed to the front and rear covers by bolts. The outer cover is a detachable cover, which is fixed by hooks in the slots of the front and rear covers.

[0008] Furthermore, a dustproof net is fixedly connected inside the first ventilation opening.

[0009] Furthermore, the casing of the distribution box is made of SMC non-metallic material.

[0010] Furthermore, the lugs are in a U-shape.

[0011] Furthermore, the cable compartment is provided with a second ventilation opening on the surface connecting it to the distribution box body, and the lower part of the connecting surface is provided with a channel for cable entry and exit; the connecting surface is equipped with a cable fixing beam for binding and fixing the incoming and outgoing cables.

[0012] Furthermore, the channel is a circular channel.

[0013] Furthermore, the channel is fitted with a silicone sleeve.

The structural design of pre-installing an inverted L-shaped metal frame and a Z-shaped lifting lug on the top of the box allows the distribution box to be directly hoisted and installed using the lifting lugs without the need for additional auxiliary tools or complicated hoisting preparations. This significantly improves on-site construction efficiency and solves the problem of hoisting difficulties caused by the lack of lifting lugs in traditional distribution boxes.

[0019] Furthermore, this utility model enhances safety performance and overall usability. The distribution box housing, made from a novel non-metallic material, SMC fire-resistant and insulating plastic, offers superior insulation and toughness compared to traditional metal housings. This effectively reduces the risk of electrical conductivity and leakage, ensuring operator safety. It is also lightweight, facilitating assembly, transportation, and installation. Due to its SMC plastic housing, it possesses superior flame-retardant properties, resulting in better fire resistance than existing metal-cased distribution boxes. The lifespan and strength of the distribution box also meet stringent usage requirements. Special design avoids the risk of water leakage during plastic housing assembly, resulting in significantly better overall performance than traditional metal distribution boxes.
