Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, and in particular relates to an assembled integrated power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the load is concentrated and there are more circuits.

[0003] The existing utility model with authorization announcement number CN220896115U discloses an assembled integrated power distribution cabinet, including a base, a top cover on the upper side of the base, two cabinets between the top cover and the base, a door panel movably connected to the front end of the cabinet, and several partitions inside the cabinet. The two cabinets, the cabinets and the base, and the top cover and the cabinets are all connected by connecting components.

[0004] The above technical solution involves setting up connecting components. When assembling the distribution cabinet, pulling the connecting plate causes the sliding rod to slide in the fixed cylinder, while the spring is compressed. Then, the insert plate at the bottom of the cabinet is inserted into the slot at the top of the base. After releasing the connecting plate, the spring extends and pushes one end of the sliding rod into the locking hole of the insert plate to limit the insertion plate, thereby achieving the effect of limiting the cabinet. However, the above technical solution relies solely on the cooperation between the insert rod and the limiting hole for connection, which is a simple plug-in structure. After being subjected to vibration, external impact, or long-term use, the insert rod is prone to loosening or accidental dislodgement, leading to cabinet disintegration or shaking, threatening the safe operation of internal electrical components, and posing a serious safety hazard.

[0005] To address these issues, we propose an integrated modular power distribution cabinet. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the simple plug-in structure in the prior art has no locking mechanism, and is prone to loosening and falling off under vibration or external force, which poses a safety hazard. Therefore, this utility model proposes an assembled integrated power distribution cabinet.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An assembled integrated power distribution cabinet includes a first cabinet. Two positioning blocks are fixedly installed on the outer surface and inner wall of the first cabinet. A second cabinet is engaged with one side of the two sets of positioning blocks that are close to each other. The upper surface of the first cabinet is in contact with the bottom surface of the second cabinet. Each set of positioning blocks has a sliding groove on one side of the two sets of positioning blocks that are close to each other. A slider is slidably connected inside each of the sliding grooves. A fixing plate is fixedly installed on one side of the two sliders that are close to each other. The outer surface of the fixing plate has two threaded openings. The outer surface of the second cabinet has two threaded holes. Two fixing bolts are provided on the outer side of the second cabinet. The end of each fixing bolt near the second cabinet passes through the threaded opening and is threadedly connected to the inner wall of the threaded hole.

[0008] Preferably, both sides of the first cabinet and both sides of the second cabinet are provided with heat dissipation vents. Two connecting plates are fixedly installed on the inner wall of each group of heat dissipation vents. A small motor is fixedly installed on the side of each group of connecting plates that are close to each other. A rotating shaft is fixedly installed at the power output end of each group of small motors. A cooling fan blade is fixedly installed on the outer surface of each group of rotating shafts.

[0009] Preferably, dust covers are snapped onto both sides of the first cabinet and both sides of the second cabinet. Each set of dust covers has several ventilation openings on the side that is far apart from each other, and each set of dust covers is located at the heat dissipation opening.

[0010] Preferably, two positioning plates are fixedly installed on the outer surface of each set of dust covers, and the side of each pair of positioning plates that is close to each other is respectively engaged with the two sides of the first cabinet and the two sides of the second cabinet.

[0011] Preferably, cabinet doors are movably hinged to the outer surfaces of the first cabinet and the second cabinet, and a door handle is fixedly installed on the outer surface of each cabinet door.

[0012] Preferably, a reinforcing block is fixedly installed on the outer surface of each door handle, and the side of each reinforcing block near the first cabinet and the side of the second cabinet are fixedly connected to the outer surfaces of the first cabinet and the second cabinet.

[0013] Preferably, two sets of mounting plates are fixedly installed on the bottom surface of the first cabinet, and each set of mounting plates is fixedly installed with a caster wheel on its bottom surface, and a stop brake assembly is provided on the outer side of each set of caster wheels.

[0014] Preferably, a lifting handle is fixedly installed on the side of the fixing plate away from the first cabinet, and two fastening blocks are fixedly installed on the outer surface of the lifting handle. The side of each fastening block near the first cabinet is fixedly connected to the side of the fixing plate away from the first cabinet.

[0015] Preferably, the upper surface of the second cabinet is provided with a plurality of heat dissipation holes, and there are at least three sets of heat dissipation holes.

[0016] In summary, the technical effects and advantages of this utility model are as follows: Through the synergistic action of positioning blocks, sliding grooves, sliders, fixing plates, and fixing bolts, a more robust and reliable mechanical locking system is constructed. Specifically, during assembly, positioning blocks on the outer surfaces and inner walls of the first and second cabinets are used for initial snap-fit ​​positioning, ensuring precise alignment of the two cabinets in the horizontal and vertical directions. This lays a solid foundation for subsequent fastening operations. By moving the slider within the sliding groove, the fixing plate is precisely moved to the corresponding position of the threaded hole on the second cabinet. This design not only facilitates alignment but also provides the connecting components with a certain degree of positional adjustment flexibility. Finally, the fixing bolts are tightened... The threaded opening of the fixed plate is screwed into the threaded hole of the second cabinet, achieving a rigid connection between the two cabinets from the outside. This bolt fastening method completely changes the easily loosened plug-in mode in the background technology. The strong biting force of the threads firmly locks the two cabinets together, effectively resisting the vibration generated during equipment operation and possible external force collisions. It fundamentally eliminates the risk of cabinet loosening, shaking, or even accidental disintegration, greatly improving the overall structural strength and stability of the assembled distribution cabinet, providing a solid and reliable guarantee for the safe operation of internal electrical components, and significantly eliminating safety hazards.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-6 An assembled integrated power distribution cabinet includes a first cabinet 1. Two positioning blocks 16 are fixedly installed on the outer surface and inner wall of the first cabinet 1. The two sets of positioning blocks 16 are connected to a second cabinet 6 on their adjacent sides. Heat dissipation vents 10 are provided on both sides of the first cabinet 1 and both sides of the second cabinet 6. Two connecting plates 9 are fixedly installed on the inner wall of each set of heat dissipation vents 10. A small motor 11 is fixedly installed on the adjacent side of each set of connecting plates 9. A rotating shaft 25 is fixedly installed at the power output end of each set of small motors 11. A cooling fan blade 26 is fixedly installed on the outer surface of each set of rotating shafts 25. By setting up heat dissipation vents 10, connecting plates 9, small motors 11, rotating shafts 25 and cooling fan blades 26, forced air cooling can be actively performed inside the cabinet, effectively reducing the heat generated by electrical components during operation, ensuring stable operation of the equipment and extending its service life.

[0021] The upper surface of the first cabinet 1 is in contact with the bottom surface of the second cabinet 6. A set of positioning blocks 16 are provided with sliding grooves 17 on their close sides. Dust covers 3 are snapped onto both sides of the first cabinet 1 and both sides of the second cabinet 6. Several ventilation openings 2 are provided on the far sides of each set of dust covers 3. Each set of dust covers 3 is located at the heat dissipation opening 10. By setting dust covers 3 and ventilation openings 2, external dust and debris can be effectively blocked from entering the cabinet while ensuring heat dissipation. This avoids the risk of reduced heat dissipation efficiency and electrical short circuits caused by dust accumulation, and improves the protection level of the equipment.

[0022] Each slide groove 17 has a slider 20 slidably connected inside. The two sliders 20 are fixedly installed on the side of each other. Two positioning plates 4 are fixedly installed on the outer surface of each set of dust covers 3. The side of each two sets of positioning plates 4 that are close to each other are respectively engaged with the two sides of the first cabinet 1 and the two sides of the second cabinet 6. By setting the positioning plates 4, the dust cover 3 can be quickly and accurately engaged and fixed to the side of the cabinet. This not only makes installation and disassembly convenient, but also ensures the stability of the dust cover 3 and prevents it from shifting or falling off due to vibration.

[0023] The outer surface of the fixed plate 12 has two threaded openings 18. The outer surfaces of the first cabinet 1 and the second cabinet 6 are both hinged with cabinet doors 21. Each cabinet door 21 is fixedly installed with a door handle 8 on its outer surface. By setting cabinet doors 21 and door handles 8, it is convenient for operators to inspect and maintain the electrical components inside the cabinet, improving the convenience and efficiency of daily work. At the same time, cabinet doors 21 also play a role in safety protection.

[0024] Two threaded holes 19 are opened on the outer surface of the second cabinet 6. A reinforcing block 7 is fixedly installed on the outer surface of each door handle 8. The side of each reinforcing block 7 near the first cabinet 1 and the side of the second cabinet 6 are fixedly connected to the outer surface of the first cabinet 1 and the outer surface of the second cabinet 6. By setting the reinforcing block 7, the connection strength between the door handle 8 and the cabinet door 21 can be significantly enhanced, avoiding the door handle 8 from loosening or being damaged when the cabinet door 21 is frequently opened and closed or pulled forcefully, thus improving the durability of the structure.

[0025] The second cabinet 6 has two fixing bolts 15 on its outer side. The bottom surface of the first cabinet 1 is fixedly installed with two sets of mounting plates 22. Each set of mounting plates 22 has a caster 23 fixedly installed on its bottom surface. Each set of caster 23 has a stop brake assembly 24 on its outer side. By setting the mounting plates 22, caster 23 and stop brake assembly 24, the entire distribution cabinet has convenient mobility and can be flexibly adjusted according to the needs of the site. The stop brake assembly 24 can ensure that the position is fixed after the movement.

[0026] Each fixing bolt 15 has a threaded opening 18 at one end near the second cabinet 6 and is threaded to the inner wall of the threaded hole 19. A lifting handle 14 is fixedly installed on the side of the fixing plate 12 away from the first cabinet 1. Two fastening blocks 13 are fixedly installed on the outer surface of the lifting handle 14. The side of each fastening block 13 near the first cabinet 1 is fixedly connected to the side of the fixing plate 12 away from the first cabinet 1. By setting up the lifting handle 14 and the fastening blocks 13, a convenient force application point is provided for the operator to move the fixing plate 12, making the alignment operation during the assembly process more labor-saving and efficient. The fastening blocks 13 enhance the structural strength of the lifting handle 14.

[0027] The upper surface of the second cabinet 6 is provided with a number of heat dissipation holes 5, with at least three sets of heat dissipation holes 5. By opening heat dissipation holes 5 on the upper surface of the second cabinet 6, the principle of hot air rising can be used to form a natural chimney effect, which helps to dissipate the heat inside the cabinet upwards. In conjunction with the active heat dissipation system, the overall heat dissipation effect is further optimized.

[0028] The working principle of this utility model is as follows: When in use, the first cabinet 1 and the second cabinet 6 are initially positioned by the positioning block 16 to ensure that they are aligned. Then, the operator holds the lifting handle 14 and uses the stability provided by the fastening block 13 to drive the fixing plate 12 and the slider 20 below it to slide in the slide groove 17 until the threaded opening 18 on the fixing plate 12 is precisely aligned with the threaded hole 19 on the side of the second cabinet 6. Finally, the fixing bolt 15 is screwed into the threaded opening 18 and the threaded hole 19 in sequence and tightened, thereby firmly connecting the first cabinet 1 and the second cabinet 6 into a whole and completing the assembly of the power distribution cabinet. After assembly, when the power distribution cabinet is put into operation, its internal electrical components will generate heat. At this time, the small motor 11 installed on the connecting plate 9 on the inner wall of the heat dissipation port 10 starts and drives the cooling fan blades 26 to rotate at high speed through the rotating shaft 25, forcibly expelling the hot air inside the cabinet to the outside, forming an active airflow circulation, which effectively reduces the temperature inside the cabinet. At the same time, the heat dissipation holes 5 opened on the upper surface of the second cabinet 6 utilize the chimney effect of the rising hot air to help dissipate the heat accumulated at the top naturally. Working together with the active heat dissipation system, it ensures that the temperature inside the cabinet is maintained within a safe range. During heat dissipation, to prevent external dust from entering the cabinet through the heat dissipation vent 10 and affecting electrical components, dust covers 3 with ventilation openings 2 are fastened to both sides of the cabinet. The dust covers 3 are securely fastened to the side of the cabinet by the positioning plate 4 on their outer surface, which can ensure air circulation and effectively block dust. When it is necessary to inspect or maintain the components inside the cabinet, the cabinet door 21 hinged to the cabinet can be opened by pulling the door handle 8. The reinforcing block 7 on the door handle 8 ensures its structural strength and can withstand frequent switching operations. If it is necessary to move the entire distribution cabinet, it can be pushed to the designated position using the mounting plate 22 at the bottom and the casters 23. Then, the casters 23 can be locked by the stop brake assembly 24 to ensure the stability of the distribution cabinet during use.
