Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a control device for a power distribution system. Background Technology

[0002] Distribution boxes play a crucial role as key equipment for power distribution, control, and protection. They distribute power to various electrical devices according to different needs, and also have overload and short-circuit protection functions to ensure the safe and stable operation of the power system.

[0003] Traditional distribution boxes are typically installed in fixed enclosures, which are generally either fully enclosed or have simple open doors. When maintenance and repair are required, the enclosed structure makes it difficult for maintenance personnel to directly access the internal electrical components. They often have to spend a lot of time and effort disassembling the various parts of the enclosure, making the operation extremely inconvenient.

[0004] While a simple hinged door design offers more flexibility in terms of opening method, the limited opening angle and range of the door result in a very narrow operating space for maintenance personnel. During maintenance, insufficient operating space may restrict the use of tools, making it difficult for maintenance personnel to fully inspect and repair electrical components located deep within the enclosure or in corners. This not only increases the difficulty of maintenance but also increases the risk of operational errors, thereby affecting maintenance efficiency and quality. Utility Model Content

Flip-openable side panels 5 are installed on both sides of the power distribution box assembly 4. A first side slide 2 and a second side slide 3, which drive the side panels 5 to rotate, are respectively installed on both sides of the housing 11. Both the first side slide 2 and the second side slide 3 are horizontally slidably connected to the housing 11. Two sets of electric cylinders, which drive the first side slide 2 and the second side slide 3, are also fixedly installed in the housing 11. An auxiliary front cover 6 is installed at the front end of the side panel 5 and is rotatably connected to the side panel 5. The base 1 serves as the bottom support for the entire device, allowing for stable placement on the ground. Furthermore, by designing the base 1 with a structure where the housing 11 and the maintenance cover 12 cooperate, the maintenance cover 12 can be easily disassembled to access the interior of the housing 11 during maintenance. The flip-open side panel 5 facilitates the inspection and maintenance of the equipment inside the distribution box 4. The electric cylinder installed in the housing 11 drives the first side slide 2 and the second side slide 3 to slide horizontally, thereby rotating and opening the side panel 5, making operation convenient and quick. The auxiliary front cover 6 further enhances the protective performance and also facilitates operation and inspection of the front end of the side panel 5.

[0028] Reference Figure 2 and Figure 3 The seat housing 11 includes a main housing 111 and support feet 112. The support feet 112 are evenly fixed to the four corners of the lower end face of the main housing 111, and guide grooves are provided on both sides of the main housing 111 for the sliding installation of the first side slide 2 and the second side slide 3. The design of the main housing 111 and support feet 112 of the seat housing 11 provides good stability to the device. The support feet 112 are evenly distributed at the four corners of the lower end face of the main housing 111, which can effectively distribute the weight of the device and prevent the device from tilting or shaking. The guide grooves on both sides of the main housing 111 provide precise guidance for the sliding of the first side slide 2 and the second side slide 3, ensuring the smooth opening and closing of the side panel 5. The main housing 111 of the seat housing 11 is made of high-strength steel plate, such as Q235 steel plate, which has good strength and corrosion resistance. The support feet 112 are made of cast iron and are evenly fixed to the four corners of the lower end face of the main housing 111 by welding. The inspection cover 12 is fixedly installed on the front end of the seat box 11 by bolts, which facilitates disassembly and installation.

[0029] Reference Figure 1 , Figure 2 and Figure 3Both the first side slide 2 and the second side slide 3 include a bent support plate 21 and a transverse sliding plate 22. The transverse sliding plate 22 is evenly installed on one side of the bent support plate 21, and one end of the transverse sliding plate 22 is fixedly connected to the bent support plate 21, while the other end of the transverse sliding plate 22 is inserted into the guide groove of the main housing 111. The first side slide 2 and the second side slide 3 adopt the structure of the bent support plate 21 and the transverse sliding plate 22, which is simple in structure and has high strength. The transverse sliding plate 22 is inserted into the guide groove of the main housing 111, which can achieve stable horizontal sliding and ensure that the rotation of the side panel 5 is accurate and reliable. The bent support plate 21 and the transverse sliding plate 22 of the first side slide 2 and the second side slide 3 are both made of aluminum alloy, which has the characteristics of light weight and high strength. The electric cylinder installed in the seat box 11 can be a DT50 electric push rod with a thrust of 500N and a stroke of 200mm. It is controlled by a Siemens S7-200 PLC controller and can accurately drive the first side slide 2 and the second side slide 3 to slide horizontally.

[0030] Reference Figure 4 The distribution box assembly 4 includes a base plate 41, a back plate 42, and a top plate 43. The top plate 43 and the base plate 41 are located at the upper and lower ends of the back plate 42, respectively, and both the top plate 43 and the base plate 41 are fixedly connected to the back plate 42. The combined structure of the base plate 41, back plate 42, and top plate 43 of the distribution box assembly 4 provides a stable installation space for the internal electrical equipment. The fixed connection between the top plate 43 and the base plate 41 and the back plate 42 ensures the overall structural strength of the distribution box assembly 4 and effectively protects the internal equipment from external impacts and vibrations. A heat dissipation plate 44 is fixedly installed on the upper surface of the top plate 43. The heat dissipation plate 44 has several sets of heat dissipation grooves, and the top plate 43 has corresponding strip grooves to facilitate better internal heat dissipation. A shielding cover 45 is fixedly installed on the upper surface of the heat dissipation plate 44. The heat dissipation plate 44 and the shielding cover 45 installed on the upper surface of the top plate 43 effectively improve the heat dissipation and protection performance of the distribution box assembly 4. The heat dissipation grooves on the heat sink 44 increase the heat dissipation area, enabling timely dissipation of heat generated inside the distribution box 4, reducing equipment temperature, and extending equipment lifespan. The shielding cover 45 prevents dust, rainwater, and other external impurities from entering the heat dissipation grooves, ensuring stable heat dissipation performance. The bottom plate 41, back plate 42, and top plate 43 of the distribution box 4 are all made of stainless steel, offering excellent corrosion resistance. The heat sink 44 is made of aluminum alloy. The shielding cover 45 is made of plastic.

[0031] Reference Figure 5The side panel 5 includes a side panel portion 51 and a connecting portion 52. The connecting portion 52 is integrally formed on the rear end face of the side panel portion 51. A connecting shaft 441 for rotating the connecting portion 52 is fixedly installed between the heat dissipation plate 44 and the main housing 111. The integral forming design of the side panel portion 51 and the connecting portion 52 of the side panel 5 makes the structure of the side panel 5 more robust. The setting of the connecting shaft 441 provides support for the rotation of the side panel 5, ensuring that the side panel 5 can be flexibly flipped open and closed. This structural design facilitates comprehensive inspection and maintenance of both sides of the distribution box group 4. A linkage shaft 511 is installed on the lower end face of the side panel portion 51 near the front end. The head of the linkage shaft 511 is fixedly connected to the side panel portion 51, and a Y-direction sliding groove 211 for mounting the linkage shaft 511 is provided on the bent support plate 21. The linkage shaft 511 on the lower end face of the side plate portion 51 engages with the Y-direction slide groove 211 on the bent support plate 21, realizing the linkage between the horizontal sliding of the first side slide 2 and the second side slide 3 and the rotation of the side box plate 5. When the first side slide 2 and the second side slide 3 slide horizontally, the linkage shaft 511 slides in the Y-direction slide groove 211, thereby driving the side box plate 5 to rotate, making the opening and closing of the side box plate 5 more automated and intelligent. The side plate portion 51 and the connecting portion 52 of the side box plate 5 are made of steel plate.

[0032] Work process:

[0033] During normal operation, the inspection cover 12, side panel 5, and auxiliary front cover 6 are all closed, which protects the distribution box group 4.

[0034] When maintenance of the distribution box group 4 is required, the control system issues a command to drive the two sets of electric cylinders in the housing 11. For example, electric cylinders controlled by servo motors can have their stroke and thrust precisely set according to the equipment size and load requirements, such as a rated thrust of 5000N, a maximum stroke of 400mm, a response time of less than 50ms, and overload protection and fault alarm functions. Alternatively, pressure-resistant and corrosion-resistant hydraulic cylinders can be selected, and precise control can be achieved with proportional valves to ensure smooth and accurate operation. The cylinders then push the first side slide 2 and the second side slide 3 horizontally outward along the guide groove.

[0035] The bent support plates 21 on the first side slide 2 and the second side slide 3 slide in the Y-direction slide groove 211 via the linkage shaft 511. Due to the design of the Y-direction slide groove 211, the sliding of the linkage shaft 511 will cause the side panel 5 to flip open around the connecting shaft 441. At the same time, the auxiliary front cover 6 also flips open, exposing the side of the distribution box assembly 4, which is convenient for maintenance personnel to inspect and repair.

[0036] After maintenance, the control system reverses the drive of the electric cylinder, causing the first side slide 2 and the second side slide 3 to slide inward. The linkage shaft 511 slides in the reverse direction in the Y-axis slide groove 211, driving the side panel 5 and the auxiliary front cover 6 to close, restoring the closed state of the power distribution box group 4.

[0037] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
