Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to an electrical equipment protection box. Background Technology

[0002] As the core protective carrier of electrical systems, the structural rationality of electrical equipment protection boxes directly affects the operational safety and maintenance efficiency of equipment. Currently, traditional electrical equipment protection boxes on the market generally suffer from two major pain points: Firstly, the simple opening and closing structure makes maintenance inconvenient. Most existing protection boxes adopt a single-leaf outward opening design. After opening, the box door can easily block the operating space, and the internal components are only visible from the front. When it is necessary to inspect the side wiring terminals or the back wiring, maintenance personnel have to reach into the box to operate, which not only restricts their movement, but also makes them prone to accidentally touching adjacent high-voltage components, posing a safety hazard.

[0003] Secondly, unreasonable internal layout leads to wasted space and safety risks. Traditional protection boxes adopt a flat, planar layout, with circuit breakers, frequency converters, terminals, and other components densely stacked on the same mounting plane, resulting in low space utilization. To save space, cables are often crisscrossed and twisted, which can easily cause component malfunctions due to signal interference between high-voltage power lines and low-voltage control lines. Furthermore, long-term compression and friction of cables can easily damage the insulation layer, increasing the probability of short-circuit faults. In addition, the overlapping heat dissipation channels of components in the planar layout can easily cause local heat accumulation, further reducing the operational stability of the equipment.

[0004] In existing technologies, although some protective boxes have attempted to optimize the door structure or add internal partitions, a systematic opening and closing layout collaborative design has not been formed: double doors still do not solve the problem of insufficient maintenance space for side components, and simply added partitions lack standardized wiring channels and still cannot avoid cable crossing. In view of the shortcomings of the existing technologies, there is an urgent need to design an electrical equipment protective box that can achieve unobstructed maintenance from all angles and significantly improve space utilization, so as to meet the high requirements of modern electrical systems for operation and maintenance efficiency and safety protection. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an electrical equipment protection box that offers advantages such as unobstructed maintenance from all angles and significantly improved space utilization, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution To achieve the above advantages of unobstructed inspection from all angles and significantly improved space utilization, the specific technical solution adopted by this utility model is as follows: an electrical equipment protection box, including a box body, a main box door set on the front of the box body, a first side door and a second side door set on the left and right sides of the box body respectively, and a three-dimensional layered plate set inside the box body. The main door is rotatably connected to the front edge of the box body via a hinge; The first side door and the second side door are mirror images of each other; the three-dimensional layered panel is a detachable metal partition with through holes, and there are 2 of them, which divide the interior of the box into an upper functional area, a middle functional area and a lower functional area, and a wiring channel is reserved between adjacent three-dimensional layered panels.

[0007] The main door has a labyrinth-style sealing groove on its edge, and a nitrile rubber sealing strip is fitted inside the sealing groove. The opening angle of the main door is ≤90°.

[0008] The main door, the first side door, and the second side door are all equipped with latches and lock handles.

[0009] The inner wall of the box is provided with an adjustment groove for sliding connection of the three-dimensional layered plate.

[0010] The upper functional area is equipped with an exhaust pipe fixedly installed on the top surface of the box, and the exhaust pipe has an exhaust port on its surface. The lower functional area is equipped with an air inlet on the bottom surface of the box, and a dustproof net is fixedly connected inside the air inlet.

[0011] The main door, the first side door, and the second side door are all equipped with viewing windows.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides an electrical equipment protection box, which has the following advantages: (1) Through the coordinated design of the main door, the first side door and the second side door, the internal structure of the box can be fully exposed in the front, left and right directions after opening. The effective operating space is significantly improved compared with the traditional single-door protection box. During operation and maintenance, there is no need to reach into the box and can directly contact the side wiring terminals, reducing the risk of accidental contact.

[0013] (2) This utility model adopts a vertical three-layer combined with a horizontal partition structure. The internal space of the box is divided into independent functional areas by a detachable metal partition. The space utilization rate is improved compared with the traditional reply. The high power line and the low power control line are arranged separately, effectively reducing the signal interference rate, avoiding heat accumulation, and reducing the probability of short circuit failure.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, an electrical equipment protection box is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an electrical equipment protection box according to an embodiment of the present utility model includes a box body 1, a main box door 11 disposed on the front of the box body 1, a first side door 9 and a second side door 10 disposed on the left and right sides of the box body 1 respectively, and a three-dimensional layered panel 3 disposed inside the box body 1.

[0020] The electrical equipment protection box uses the enclosure 1 as its basic frame, and its core structure includes four key components. The main door 11 is located on the front of the enclosure 1, providing frontal protection and opening / closing functionality. The first side door 9 and the second side door 10 correspond to the left and right sides of the enclosure 1, respectively, addressing the deficiency of insufficient side maintenance space in traditional protection boxes. A three-dimensional layered panel 3 is placed inside the enclosure 1 to optimize the internal space layout and solve the problem of dense component stacking. Together, these four components constitute a comprehensive structure of "multi-directional protection + layered layout."

[0021] The main door 11 is rotatably connected to the front edge of the box body 1 via a hinge.

[0022] The main door 11 is connected by a hinge. The hinge is installed on the front edge of the housing 1 to ensure that the main door 11 can rotate flexibly around the hinge and achieve stable opening and closing. The hinge selection should match the weight and usage frequency of the main door 11 to ensure that it can maintain good rotation performance after long-term use and avoid jamming that affects maintenance operations.

[0023] The first side door 9 and the second side door 10 are mirror images of each other; the three-dimensional layered panel 3 is a removable metal partition with through holes 4, and there are 2 of them, which divide the interior of the cabinet 1 into an upper functional area, a middle functional area and a lower functional area. Wiring channels are reserved between adjacent three-dimensional layered panels 3. The mirrored design means that the dimensions, structure, and installation position of the first side door 9 and the second side door 10 are completely symmetrical, ensuring consistent protection performance on both sides of the enclosure 1, while also facilitating standardized production and component replacement; the three-dimensional layered panel 3 is made of metal, which not only has sufficient support strength to support electrical components, but also assists in heat dissipation; the through holes 4 can promote air circulation inside the enclosure and reduce local heat accumulation; the two partitions are divided into three functional areas according to the characteristics of electrical components, such as placing lightweight control components such as sensors and indicator lights in the upper layer, placing core power components such as circuit breakers and frequency converters in the middle layer, and placing wiring terminals and power busbars in the lower layer; the reserved wiring channels can realize the separate arrangement of high-voltage and low-voltage cables, avoiding cross-entanglement and reducing signal interference and short-circuit risks.

[0024] As shown in Figures 1, 2, 3 and 4, the main door 11 has a labyrinth-type sealing groove on its edge, and a nitrile rubber sealing strip is fitted inside the sealing groove. The opening angle of the main door 11 is ≤90°.

[0025] Unlike traditional single grooves, the labyrinth-style sealing groove features a tortuous path design. Combined with nitrile rubber sealing strips, it possesses aging resistance, oil resistance, and high and low temperature resistance, making it suitable for various working conditions such as outdoor and industrial applications. It can significantly improve sealing performance and effectively prevent rainwater and dust from entering the enclosure. The opening angle of ≤90° is designed based on actual usage scenarios, which can meet the needs of maintenance operations while avoiding excessive opening of the door and occupying surrounding space. At the same time, it can prevent the door from being damaged or deformed due to excessive rotation caused by external forces such as wind or collisions.

[0026] As shown in Figures 1, 2, and 3, the main door 11, the first side door 9, and the second side door 10 are all equipped with latches 13 and handles 14.

[0027] All three doors are equipped with a combination of latch 13 and handle 14. The latch 13 is used to lock the door after it is closed, which can prevent unauthorized personnel from opening the protection box and ensure the safe operation of electrical equipment. The handle 14 provides a force point for opening and closing the door. It is designed to take into account both grip comfort and anti-slip performance, so that maintenance personnel can quickly and effortlessly complete the opening and closing operations.

[0028] As shown in Figures 1, 2, 3 and 4, the main door 11, the first side door 9 and the second side door 10 are all equipped with viewing windows 12.

[0029] The viewing window 12 is made of high-transmittance, voltage-resistant polycarbonate material. Maintenance personnel can observe the operating status of the components inside the box through the viewing window 12 without opening the door, reducing unnecessary door opening operations and lowering the risk of dust intrusion and component exposure.

[0030] As shown in Figures 1, 2, 3 and 4, the inner wall of the box 1 is provided with an adjustment groove 2 for sliding connection of the three-dimensional layered plate 3.

[0031] Adjustment slot 2 provides a sliding mounting track for the three-dimensional layered board 3. Maintenance personnel can flexibly adjust the position of the layered board according to the size and height of electrical components, so that the protection box can be adapted to components of different specifications. There is no need to replace the entire protection box due to changes in component size, which greatly improves the versatility and reusability of the equipment.

[0032] As shown in Figures 1 and 2, an exhaust pipe 7 is fixedly installed on the top surface of the upper functional area corresponding to the box 1, and an exhaust port 8 is opened on the surface of the exhaust pipe 7. An air inlet 5 is provided on the bottom surface of the lower functional area corresponding to the box 1, and a dustproof net 6 is fixedly connected inside the air inlet 5.

[0033] This structure constructs a natural convection cooling system with bottom inlet and top outlet. Cold air enters the box from the air inlet 5 on the bottom surface of the box 1. As it flows through the three functional areas of the lower, middle and upper sections, it absorbs the heat generated by the electrical components and becomes hot air. It is then discharged from the exhaust pipe 7 on the top surface of the box 1 through the exhaust port 8, thereby achieving temperature control inside the box. The dust filter 6 inside the air inlet 5 can filter dust and impurities in the air, preventing them from adhering to the surface of the components and affecting the heat dissipation efficiency and insulation performance.

[0034] Working Principle: First, based on the enclosure 1 as the basic frame, the main door 11, the first side door 9, and the second side door 10 form an all-round sealed protection through a labyrinth-type sealing groove and nitrile rubber sealing strip, blocking external rainwater and dust from entering. At the same time, the latches 13 on the three doors can lock the doors to prevent unauthorized operation and ensure equipment safety. During daily operation and maintenance, maintenance personnel can observe the operating status of the components inside the enclosure through the viewing windows 12 on the three doors without opening the doors, and make a preliminary judgment on the equipment condition. When maintenance is required, the main door 11 is opened after unlocking the locks to expose the front components, and the first side door 9 and the second side door 10 are opened to expose the side wiring terminals, realizing unobstructed operation from all angles. If the component size changes, the height of the three-dimensional layered plate 3 can be adjusted by sliding the adjustment groove 2 to adapt to maintenance needs. In terms of heat dissipation, a natural convection is formed inside the enclosure, with the air entering from the bottom and exiting from the top. Cold air enters through the dust filter 6 of the air inlet 5, absorbs the heat of the components in each functional area, and then the hot air is discharged from the exhaust port 8 of the exhaust pipe 7, which, together with the three-dimensional layered plate 3, provides heat dissipation. The through-hole 4 assists in air circulation and effectively controls the temperature inside the box; in addition, the wiring channels between adjacent layers allow for independent routing of high-voltage and low-voltage cables, avoiding signal interference, further reducing the probability of failure, and ensuring the stable operation of electrical equipment.
