[0030] Working principle: When in use, the distribution box body 4 is mainly composed of three parts: electrical cabinet A1, electrical cabinet B2 and electrical cabinet C3. The distribution box body 4 can be designed as a three-fold openable structure, and its interior is divided into three groups of accommodating areas. Additional equipment or maintenance settings can be installed inside each electrical cabinet. Electrical cabinets A1, B2 and C3 can be flexibly partitioned according to the size and function of different electrical components, which is convenient for reasonable planning of the internal space, making the components in the distribution box more neatly and compactly arranged, effectively utilizing limited space and avoiding space waste; if electrical components need to be added or some functions need to be expanded at a later stage, they can be reasonably arranged in the corresponding accommodating area without large-scale transformation of the entire distribution box, and it has good scalability and adaptability; convenient operation and maintenance The three-fold openable structure can make the electrical cabinets A1, B2 and C3 inside the distribution box fully exposed at the same time, and the operator can intuitively see the layout and status of all electrical components, which is convenient for quick positioning and inspection of faults, reducing Maintenance time and difficulty; electrical cabinets A1, B2 and C3 are independent of each other, and electrical components of different voltage levels and functions can be arranged separately, effectively preventing mutual interference and short circuit risks between electrical components, and improving the safety and reliability of the distribution box; in the event of an emergency such as an electrical fire, each group of accommodating areas in the three-fold structure can play a certain fire isolation role, delaying the spread of fire, buying more rescue time for firefighters, and reducing the impact of the fire on the entire distribution system; when the three-fold open structure is in the open state, the electrical cabinets A1, B2 and C3 inside the distribution box can be fully exposed to the air, which is conducive to the natural circulation of air, accelerates heat dissipation, reduces the temperature inside the distribution box, avoids performance degradation or failure due to overheating of electrical components, and extends the service life of electrical components; the heat dissipation holes and fans on the side of electrical cabinets A1, B2 and C3 are designed for targeted heat dissipation to improve heat dissipation efficiency and ensure that the distribution box can maintain good heat dissipation performance under various working environments;

[0031] When the interior of the distribution box body 4 is opened for inspection, the force-bearing seat 12 is pulled outward, and under the action of the crank synchronization mechanism 5, the electrical cabinet C3 is separated from the upper surface of the electrical cabinet B2, and the top cover 59 is opened from the upper surface of the electrical cabinet C3, thereby completing the purpose of exposing the electrical cabinets A1, B2 and C3 simultaneously. The synchronous opening and closing design facilitates operators to inspect, maintain or replace components inside the electrical cabinets A1, B2 and C3 at one time, without having to open or close different areas one by one, thereby improving work efficiency and reducing the risk of misoperation caused by frequent opening and closing of different areas.

[0032] When the electric cabinet C3 is in the open state, the bottom right side of the electric cabinet C3 is suspended. At this time, the connecting plate 61 that is connected to the damping groove 65 is taken out, and the supporting leg 64 inside the connecting plate 61 is pulled out, and the bottom of the supporting leg 64 is supported on the ground. At the same time, the nut is locked and fixed on the stud 63. The two sets of supporting legs 64 can support and fix the electric cabinet C3 to prevent the center of gravity of the distribution box body 4 from being unstable and tipping over. The supporting mechanism 6 can provide additional supporting force for the top electric cabinet C3 when the distribution box body 4 is opened, and share part of the weight of the top electric cabinet C3. to the ground or other supports, reducing the pressure on the connection of the three-fold structure, thereby enhancing the stability of the entire distribution box body 4 in the open state and preventing the folding structure from being deformed or damaged due to the excessive weight of the top electric cabinet C3; when the distribution box body 4 is overhauled, the support mechanism 6 can be folded and stored, specifically, the support legs 64 are inserted into the receiving groove inside the connecting plate 61 and folded 90 degrees to be snapped into the damping groove 65, reducing the space occupied by the entire distribution box body 4, and facilitating the layered docking of the electric cabinets A1, B2 and C3 after the overhaul is completed.

[0035] Specific embodiment four: This embodiment is a further limitation of specific embodiment one. The electric cabinet A1 synchronously drives the electric cabinet C3 and the top cover 59 to move through the crank synchronization mechanism 5 located on both sides of the distribution box body 4. The crank synchronization mechanism 5 includes a guide groove 51, a guide column 52, a drive groove 521, a connecting rod A53, a center column 54, a connecting rod B55, a connecting rod C56, a connecting rod D57, a transmission seat 58 and a top cover 59; a drive groove 521 is opened on both side walls of the end of the electric cabinet A1.

[0036] Specific embodiment five: This embodiment is a further limitation of specific embodiment four, and the interior of the driving groove 521 is interspersed with a guide column 52, and the guide column 52 is inserted into the interior of the guide groove 51. The guide groove 51 is set in a "C" shape, and the guide groove 51 is set in two groups and is respectively opened on the two side walls of the distribution box body 4; a connecting rod A53 is movably installed on the outer side of the guide column 52, and a center column 54 is movably installed in the middle of the connecting rod A53, and the end of the center column 54 is installed on the side wall of the distribution box body 4, and the side of the connecting rod A53 away from the guide column 52 is movably connected to the outer side wall of the electrical cabinet C3 through a pin shaft.

At this time, the connecting rod A53 uses the central column 54 as a fulcrum to drive the electric cabinet C3 to move upward and backward and separate from the upper surface of the electric cabinet B2. At the same time, since the connecting rod A53 and the connecting rod B55 are arranged in parallel, the angle between the connecting rod B55 and the connecting rod C56 is reduced, and the angle between the connecting rod C56 and the connecting rod D57 is increased, so that the top cover 59 is separated from the upper surface of the electric cabinet B2, thereby achieving the opening of the electric cabinet. A1, B2 and C3 can be opened synchronously, and vice versa, push the A1 inward to close the A1, B2 and C3 synchronously. Only one operation is needed to open or close the A1, B2 and C3 at the same time, without operating the switch of each cabinet one by one, which greatly saves operation time and improves work efficiency. When it is necessary to quickly inspect, maintain or shut down all electrical equipment in the distribution box, this synchronous operation can be achieved quickly, reducing the number of operation steps and time delays. Synchronous opening or closing avoids omissions or misoperation that may occur when operating the cabinets one by one. , the interior of cabinet A1, cabinet B2 and cabinet C3 are fully exposed at the same time, maintenance personnel can see the layout and status of electrical components in all cabinets at a glance, which is convenient for rapid and comprehensive inspection and timely discovery of potential problems such as component damage and line aging; this comprehensive visual feature helps to improve maintenance efficiency and reduce troubleshooting time; for some tasks that require unified maintenance of the entire distribution box, such as cleaning and tightening terminal blocks, the synchronous opening design allows maintenance personnel to operate all cabinets at once without having to repeatedly open and close different cabinets, improving the convenience and integrity of maintenance work; the layered design makes cabinets A, B and The electrical cabinets C can be reasonably distributed in the vertical direction of the distribution box body 4, making full use of the spatial height of the distribution box body 4 to achieve efficient use of space; this compact layout can accommodate more electrical equipment in a limited space to meet the power distribution needs of different users; the electrical cabinets arranged in layers and capable of synchronous operation make the appearance of the distribution box more neat and beautiful; the size and position of each electrical cabinet are relatively fixed, and the overall structure is more regular, which not only enhances the visual effect of the distribution box, but also helps to create a neat and orderly environment at the installation site; fixed frames can be installed inside the electrical cabinets A1, B2 and C3 for installing different types of electrical equipment.
