Description

Technical Field

[0001] This utility model relates to the field of electrical engineering, and in particular to a distribution box that is easy to maintain. Background Technology

[0002] With the rapid development of the power industry and the continuous growth of electricity demand, early distribution boxes had simple structures and mainly functioned to achieve basic circuit on / off control and simple power distribution. Distribution boxes have gradually developed towards intelligence, miniaturization, and high performance. Modern distribution boxes not only have multiple protection functions, but also realize remote monitoring and automated control.

[0003] The base is securely connected to the mounting surface of the box with bolts and screws, providing a solid support foundation for the entire electrical box. The box door is connected to the main body of the electrical box with hinges, forming an openable structure. With the addition of waterproof eaves, rain shelters and other components, rainwater is prevented from seeping into the electrical box and damaging the electrical equipment. A handle is installed on the box door for easy opening and closing by staff.

[0004] Currently, in traditional distribution boxes, the wiring of internal electrical components is mostly distributed directly inside the box. Although the wiring harnesses for corresponding components are centrally organized and fixed, the wiring between multiple switches is still distributed in the same space. This makes it inconvenient for operators to identify the connection harnesses of the corresponding switches during subsequent maintenance. Furthermore, during ventilation and heat dissipation, dust and debris easily accumulate inside the distribution box, especially at ventilation holes, fans, and component surfaces. This affects airflow and hinders heat dissipation. Dust accumulation on component surfaces also affects heat dissipation, causing component temperatures to rise. Therefore, a distribution box that is easier to maintain is proposed to solve these problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a distribution box that is easy to maintain. It aims to improve the problem that the connection harnesses inside the distribution box are relatively concentrated in the existing technology, which requires careful identification during maintenance, and that debris and dust in the air can easily enter and accumulate inside the box during ventilation and heat dissipation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A power distribution box that is easy to maintain includes a base, a ventilation duct fixedly connected to the top of the base, a rain shelter fixedly connected to the top of the ventilation duct, a fan installed inside the rain shelter, a filter fixedly connected to the top of the rain shelter, a waterproof awning fixedly connected to the top of the filter, an electrical box fixedly connected to both sides of the ventilation duct by bolts, and louvers fixedly connected to the outside of the electrical box.

[0007] As a further description of the above technical solution: The electrical box has an air duct on the side near the ventilation pipe. A fixed wire clamp is fixedly connected to the middle of the air duct. Moving wire clamps are slidably connected to both sides inside the air duct. Screws are rotatably connected to both sides of the moving wire clamps.

[0008] As a further description of the above technical solution: The two adjacent electrical boxes are connected by bolts.

[0009] As a further description of the above technical solution: The electrical box has a door connected to one side by a hinge, and the door is equipped with a handle.

[0010] As a further description of the above technical solution: The electrical box is fixedly connected to a guide rail.

[0011] As a further description of the above technical solution: The two electrical boxes at the bottom are fixedly connected to the top of the base, and the two electrical boxes at the top are fixedly connected to the bottom of the rain shelter.

[0012] As a further description of the above technical solution: The screw is threaded into the inside of the clamp.

[0013] As a further description of the above technical solution: The screw is threaded into the inside of the clamp.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by combining ventilation pipes, air ducts and louvers, a heat dissipation aerodynamic layout from the center to both sides is achieved, which enables the modularly assembled distribution box to reduce the number of fans used in terms of ventilation and heat dissipation, ensuring efficient heat dissipation while reducing its energy consumption.

[0015] 2. In this utility model, the combination of the fixed wire clamp, the moving wire clamp, and the screw structure allows the entire structure to move and clamp vertically, solving the problem of messy wiring layout and providing better fixation and storage. This allows the wire harnesses of corresponding switches to be separated by the wire clamps, and different switch component wire harnesses to be separated by different air duct zones, providing convenience for subsequent maintenance.

A rain cover 8 is fixedly connected to the top of the ventilation pipe 2. A fan 15 is installed inside the rain cover 8. A filter 7 is fixedly connected to the top of the rain cover 8. The filter 7 can effectively filter impurities and dust in the air. A waterproof eave 6 is fixedly connected to the top of the filter 7. The sun cover and the waterproof eave 6 work together to form a protective barrier to prevent rainwater from entering and protect the internal electronic components. Power boxes 16 are fixedly connected to both sides of the ventilation pipe 2 by bolts 9. Louvers 12 are fixedly connected to the outside of the power box 16.

Air is continuously supplied to the electrical box through the air duct 10. A fixed wire clamp 17 is fixedly connected in the middle of the air duct 10. Moving wire clamps 14 are slidably connected on both sides inside the air duct 10. The moving wire clamps 14 and the fixed wire clamps can be used to organize the wire bundle in an orderly manner and keep the electrical box clean and tidy. Screws 13 are rotatably connected on both sides of the moving wire clamp 14.
