Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and specifically to a modular combined outdoor distribution box. Background Technology

[0002] A distribution box is a low-voltage terminal power distribution device, consisting of a box body, circuit breakers, residual current devices (RCDs), and grounding bars. It centrally distributes 220V / 380V power and provides overload, short-circuit, and leakage protection. Types include household PZ30 lighting boxes, industrial power boxes, outdoor rainproof boxes, and metering boxes. Each box can independently control its respective branch circuit, facilitating maintenance and preventing electric shock and fire risks. It can be recessed, surface-mounted, or floor-mounted and is widely used in residences, shops, factories, and outdoor facilities.

[0003] Currently available outdoor rainproof distribution boxes generally suffer from two prominent defects: First, the box structure design makes it difficult to compress storage and transportation volume, resulting in high transportation costs. Traditional finished products are mostly prefabricated integrated structures. To meet the needs of direct on-site assembly, the overall size of the box is fixed and cannot be folded or disassembled. When transporting in bulk, it occupies a lot of storage and truck space, significantly increasing logistics expenses. Another option is a modular assembly solution, which can be disassembled to reduce transportation volume, but the on-site assembly process is complicated. Workers need to carry a large number of bolts, screws, and other fasteners to tighten them one by one. The outdoor working environment is limited, which greatly increases construction time and manpower consumption, and increases the difficulty of on-site construction. Second, the box has insufficient ability to control moisture inside. Moisture intrusion can easily cause short circuits and damage to internal electrical components. Conventional rainproof boxes rely solely on the top rainproof cover to block direct rainwater, offering only a single form of protection. Water splashed up by vehicles and rainwater can easily seep into the box through ventilation gaps on both sides. Additionally, during rainy seasons and the plum rain season when air humidity is high, suspended water vapor in the environment will continuously enter the box through the ventilation openings, condensing into water droplets on the surfaces of switches and copper busbars. Over time, this accumulation can cause a decrease in wiring insulation, corrosion of metal parts, and ultimately lead to leakage and short circuit faults, shortening the service life of the power distribution equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a modular outdoor power distribution box, which adopts a modular design, facilitates transportation and quick assembly and disassembly, and can improve the water vapor control effect.

[0015] The beneficial effects of this invention are: 1. This invention adopts a modular structure, allowing components to be completely disassembled and stacked, significantly reducing storage and transportation volume and substantially lowering transportation costs. The box body uses a plug-in limiting and quick-release assembly structure, which is convenient to assemble, provides stable alignment, and effectively prevents detachment; combined with a large and small gear reduction structure, it greatly reduces the amount of manual locking operations, saving labor and increasing efficiency. At the same time, the ratchet unidirectional self-locking structure prevents structural loosening, greatly improving the overall assembly stability of the box body, and unlocking and disassembling are simple, making it suitable for rapid outdoor assembly and disassembly operations.

[0016] 2. This invention employs a circuitous air intake structure, fundamentally preventing water from splashing into the enclosure from the ground, thus completely solving the short-circuit defect of traditional distribution boxes caused by water ingress. Utilizing a heat-conducting fin for heat exchange and dehumidification, and a water collection box for water storage and drainage, it balances heat dissipation and drying effects. In high-humidity environments, it can automatically seal the ventilation slots and switch ventilation modes, effectively preventing humid air from entering the enclosure, significantly reducing the risk of component corrosion and short-circuit failures, significantly improving the equipment's outdoor weather resistance and operational reliability, and extending its service life.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] like Figures 1 to 15 As shown: A modular outdoor distribution box includes a base 1, a column 11, a box panel 12, a roof 13, a locking assembly 2, and a waterproof and heat dissipation assembly 3. The base 1 has a mounting groove 10 on its top, and the column 11 and the box panel 12 are inserted into the mounting groove 10. The column 11 has a slot 110 on its top, and the slot 110 is inserted into the end of the box panel 12. The roof 13 abuts against the column 11 and the box panel 12. The locking assembly 2 is used to lock the column 11 to the base 1 and the roof 13. The box panel 12 has a ventilation groove 120 on one side, and the waterproof and heat dissipation assembly 3 is used to prevent water vapor from passing through the ventilation groove 120.

[0039] When assembling the distribution box outdoors, first fix the base 1 to the ground with expansion bolts. Then, insert multiple uprights 11 into the four corners of the mounting slots 10. Install the waterproof heat dissipation components 3 onto the side panels 12 using the quick-release mechanism 5. Next, insert the ends of the panels 12 into the slots 110, forming a quadrangular prism structure with the panels 12 and uprights 11. Then, cover the top of the panels 12 with the canopy 13 and lock the base 1, uprights 11, and canopy 13 together using the locking components 2. This completes the assembly. The ventilation slots 120 on the panels 12 provide cooling. The distribution box adopts a modular design, dividing the distribution cabinet into multiple plate-like and rod-like structures, which facilitates reduced transportation costs. The overall assembly is simple and quick, making it suitable for outdoor field operations.

[0040] like Figure 3 As shown: The number of uprights 11 and the number of boxes 12 are both multiple and can be combined into a quadrangular prism structure. The multiple uprights 11 are respectively inserted and matched with the four corners of the mounting slot 10, and the slot 110 has a U-shaped structure.

[0041] The slot 110 is designed with a U-shaped structure, which can not only adapt to the existing end structure of the box plate 12, but also effectively prevent the two from slipping off.

[0042] like Figures 1 to 11 As shown: The locking assembly 2 includes a slide rod 20, a guide block 21, a first spring 200, and a first limiting rod 22. The slide rod 20 is slidably connected to the column 11, and the guide block 21 is slidably connected to the base 1. The slide rod 20 passes through the base 1 and abuts against the guide block 21. One end of the first spring 200 is fixedly connected to the slide rod 20, and the other end of the first spring 200 is fixedly connected to the column 11. One end of the guide block 21 has a sloping structure, and a trapezoidal groove 210 is provided on the top of the guide block 21. The inner wall of the trapezoidal groove 210 is fixedly connected to the first limiting rod 22, and the first limiting rod 22 is inserted into the slide rod 20.

[0043] The bottom of the canopy 13 has multiple grooves 130 that engage with the slide rod 20. The grooves 130 have a horizontal allowance for the slide rod 20 to slide. The locking assembly 2 also includes a second limiting rod 23, which is fixedly connected to the grooves 130. The top of the slide rod 20 has a hook-shaped structure and engages with the second limiting rod 23. When the bottom of the slide rod 20 is at one end of the guide block 21, the top of the slide rod 20 is inside the column 11. When the bottom of the slide rod 20 is in contact with the top of the guide block 21, the top of the slide rod 20 is in the groove 130 and can slide horizontally. When the bottom of the slide rod 20 is in contact with the bottom wall of the trapezoidal groove 210, the top of the slide rod 20 engages with the second limiting rod 23 and the opening is inside the column 11.

[0044] The locking assembly 2 also includes a bidirectional screw 24, a pair of sliding plates 25, a rotating shaft 26, a first gear 260, and a second gear 240. The bidirectional screw 24 is rotatably connected to the base 1 and threadedly connected to the sliding plates 25. The threads of the two sliding plates 25 are in opposite directions. The sliding plates 25 are fixedly connected to the guide blocks 21. There are multiple guide blocks 21 symmetrically arranged on both sides of the base 1. The rotating shaft 26 is rotatably mounted on the base 1 and coaxially connected to the first gear 260. The second gear 240 is coaxially connected to the bidirectional screw 24, and the first gear 260 and the second gear 240 mesh.

[0045] The locking assembly 2 also includes a sleeve 27, a triangular bolt 28, and an anti-rotation mechanism 4. The sleeve 27 passes through the base 1 and is fixedly connected to it. The sleeve 27 is rotatably connected to the rotating shaft 26. The triangular bolt 28 passes through the sleeve 27 and is coaxially connected to the rotating shaft 26. The triangular bolt 28 is slidably connected to the rotating shaft 26. The anti-rotation mechanism 4 is used to prevent the rotating shaft 26 from rotating in the opposite direction.

[0046] After the box plate 12 is installed, the bottom of the slide rod 20 abuts against one end of the guide block 21. The worker uses a triangular wrench to rotate the triangular bolt 28, which drives the rotating shaft 26 and the first gear 260 to rotate. Through the meshing transmission of the first gear 260 and the second gear 240, the bidirectional screw 24 is driven to rotate. Then, through the thread transmission between the bidirectional screw 24 and the slide plate 25, the two slide plates 25 slide in opposite directions, while driving multiple guide blocks 21 to slide synchronously. As the guide block 21 moves, the slide rod 20 is lifted along the inclined surface at one end of the guide block 21. The slide rod 20 slides along the column 11 and compresses the first spring 200. When the slide rod 20 abuts against the top of the guide block 21, the hook-shaped structure at the top of the slide rod 20 slides out of the column 11. At this time, the canopy 13 is moved so that the slide rod 20 is inserted into the groove 130, and the canopy 13 is moved horizontally so that the hook-shaped structure at the top of the slide rod 20 engages with the second limiting rod 23. At this time, the canopy 13 abuts against the column 11 and the box plate 12. Then the guide block 21 continues to move, and the bottom of the slide rod 20 slides into the trapezoidal groove 210 under the push of the first spring 200, so that the first limiting rod 22 engages with the bottom of the slide rod 20. At this time, the opening at the top of the slide rod 20 slides into the column 11, so that the base 1 and the canopy 13 are tightly connected by the engaging action of the column 11 and the slide rod 20. The number of teeth on the first gear 260 is greater than that on the second gear 240, which reduces the number of turns required to rotate the triangular bolt 28, making operation easier.

[0047] like Figures 1 to 11 As shown: The anti-rotation mechanism 4 includes a connecting rod 40, a rotating seat 41, a pawl 42, a gear plate 43, and a torsion spring 44. One end of the connecting rod 40 is rotatably connected to the triangular bolt 28. The connecting rod 40 passes through the sleeve 27 and is slidably connected to it. The other end of the connecting rod 40 abuts against one end of the pawl 42. The rotating seat 41 is fixedly connected to the base 1. The middle part of the pawl 42 is rotatably connected to the rotating seat 41. The other end of the pawl 42 abuts against the gear plate 43. The gear plate 43 is coaxially connected to the rotating shaft 26. The torsion spring 44 is sleeved in the middle of the pawl 42. One end of the torsion spring 44 is fixedly connected to the pawl 42, and the other end of the torsion spring 44 is fixedly connected to the rotating seat 41.

[0048] When the triangular bolt 28 rotates counterclockwise, the teeth on the gear plate 43 push open the pawl 42, allowing the rotating shaft 26 to rotate smoothly and lock the column 11. Simultaneously, the rotation of the pawl 42 drives the torsion spring 44 to twist, and the spring's rebound causes the pawl 42 to rotate back to its original position, ensuring that the pawl 42 always contacts the gear plate 43. Conversely, the pawl 42 and the teeth on the gear plate 43 abut against each other, preventing the slide rod 20 from automatically rising and falling, thus improving assembly stability. When the distribution box needs to be removed, use a triangular wrench to first push the triangular bolt 28 to slide a certain distance along the rotating shaft 26, simultaneously moving the connecting rod 40. The connecting rod 40 then pushes the pawl 42, causing it to rotate around the central rotating seat 41, separating the end of the pawl 42 from the gear plate 43. Then, rotating the triangular wrench clockwise allows the guide block 21 to slide back to its original position. Repeating the installation operation in reverse allows for quick disassembly.

[0049] like Figures 1 to 3 as well as Figures 12 to 15 As shown: The waterproof heat dissipation component 3 includes a duct 30, a heat-conducting plate 32, and a quick-release mechanism 5. The duct 30 is detachably connected to the box plate 12 through the quick-release mechanism 5. A vent 300 is provided on one side of the duct 30, and a ventilation slot 120 is located above the vent 300. The heat-conducting plate 32 passes through the box plate 12 and is fixedly connected to it. The bottom of the heat-conducting plate 32 is attached to the bottom wall of the duct 30. The bottom of the duct 30 has a box-shaped structure and a drain outlet 302.

[0050] The waterproof heat dissipation assembly 3 also includes a pair of baffles 33, a pair of racks 34, a spur gear 35, and a motor 36. The motor 36 is fixedly connected to the air duct 30. The output shaft of the motor 36 is coaxially connected to the spur gear 35. The two racks 34 mesh with the two sides of the spur gear 35 respectively. The racks 34 are fixedly connected to the baffles 33. The baffles 33 are slidably connected to the air duct 30. An air outlet 301 is opened on the side wall of the air duct 30. The two baffles 33 are used to block the air outlet 301 and the ventilation slot 120 respectively.

[0051] The duct 30 is installed flush against the box panel 12 using the quick-release mechanism 5. At this point, outside air flows upwards through the vent 300 before entering the box via the ventilation slot 120, preventing splashed water droplets from directly entering through the ventilation slot 120. Simultaneously, the heat-conducting plate 32 directs the heat from inside the box to the duct 30, evaporating moisture as air flows in, effectively removing water vapor. Water droplets entering the duct 30 collect in the bottom box structure, and the heat-conducting plate 32 extends into the box structure, further utilizing the cooling properties of water. The drain outlet 302 at the bottom of the duct 30 can be sealed with a rubber stopper; removing the stopper allows excess water to drain.

[0052] When there is too much moisture in the outdoor air, the motor 36 is powered on, and its output shaft drives the spur gear 35 to rotate. Through the meshing transmission between the spur gear 35 and the rack 34, the two baffles 33 slide synchronously in opposite directions, blocking the ventilation slot 120 and opening the air outlet 301. At this time, the airflow flows between the air outlet 301 and the ventilation opening 300, which can not only avoid the risk of air containing a lot of moisture entering the box, but also achieve heat dissipation through the heat conduction plate 32, further improving the practicality of the outdoor power distribution box.

[0053] like Figure 14 As shown: The quick-release mechanism 5 includes an inclined plate 50, a guide strip 51, a locking block 52, a second spring 53, and a top rod 54. The inclined plate 50 and the guide strip 51 are both fixedly connected to the box plate 12. The inclined plate 50 is inserted into the top of the air duct 30. A protruding strip 31 is fixedly connected to the end of the air duct 30. The protruding strip 31 is inserted into the guide strip 51. A slot 310 is opened at one end of the protruding strip 31. The slot 310 is engaged with the locking block 52. The locking block 52 is slidably connected to the guide strip 51. One end of the second spring 53 is fixedly connected to the locking block 52. The other end of the second spring 53 is fixedly connected to the guide strip 51. The top rod 54 passes through the guide strip 51 and is slidably connected to it. The top of the top rod 54 and the bottom of the locking block 52 are both inclined structures and abut against each other.

[0054] Before connecting the housing 12 and the base 1, install the duct 30 to avoid obstructing installation. Move the duct 30, align the protrusions 31 on both sides of the duct 30 with the two guide strips 51 and insert them. The protrusions 31 push the locking block 52 to slide and compress the second spring 53 until the locking groove 310 on the protrusion 31 moves to the locking block 52. The second spring 53 rebounds and pushes the locking block 52 to engage with the locking groove 310. At this time, the top of the duct 30 is inserted into the inclined plate 50, realizing the quick installation of the duct 30. When disassembly is required, lift the top rod 54 upwards. Through the mutual abutment between the rod and the inclined surface between the rod and the locking block 52, the locking block 52 is pushed to slide and separate from the locking groove 310, which can achieve quick disassembly.

[0055] In this embodiment, the modular outdoor distribution box is first fixed to the ground with expansion bolts. Then, multiple columns 11 are inserted into the mounting slots 10 at the four corners of the base 1. The air duct 30, which also has the function of guiding air and dehumidifying, is pre-installed on the two side panels 12 using the quick-release mechanism 5. When assembling the air duct 30, the protrusions 31 on both sides of the air duct 30 are aligned with the guide strips 51 of the base 1 and inserted. The protrusions 31 squeeze the locking block 52 and compress the second spring 53. After the slots 310 are aligned, the second spring 53 rebounds and drives the locking block 52 to lock with the slot 310. The top of the air duct 30 simultaneously abuts against the inclined plate 50 to complete the locking. When disassembling, the lifting rod 54 pushes the locking block 52 away from the slot 310 by the inclined surface, and the air duct 30 can be quickly removed. The pre-assembly of the air duct 30 can avoid interference during the subsequent installation of the panel 12. Then, the ends of each box panel 12 are inserted into the slots 110 on the column 11. The U-shaped slots 110 not only fit the shape of the ends of the box panels 12 but also prevent slippage. Multiple box panels 12 and columns 11 are fitted together to form a quadrangular prism box frame. Then, the canopy 13 is placed on top of the box panels 12. The base 1, column 11 and canopy 13 are locked together by turning the triangular bolts 28 with a triangular wrench. When the triangular bolt 28 is rotated, it drives the rotating shaft 26 and the first gear 260 with more teeth to rotate synchronously. The first and second gears 240 mesh and speed up the transmission, driving the bidirectional screw 24 to rotate. The threaded pair drives the two sliding plates 25 to move in opposite directions and links multiple guide blocks 21 to slide synchronously. During the movement of the guide blocks 21, the sliding rod 20 is lifted by the inclined surface. The sliding rod 20 moves up along the column 11 and compresses the first spring 200. After the hook-shaped structure at the top of the sliding rod 20 extends out of the column 11, the roof 13 is moved horizontally, so that the sliding rod 20 is inserted into the groove 130 of the roof 13 and the roof 13 is adjusted horizontally so that the hook-shaped structure engages with the second limiting rod 23 in the roof 13. After the guide block 21 continues to move, the first spring 200 rebounds and pushes the bottom of the sliding rod 20 into the trapezoidal groove 210 of the guide block 21. The first limiting rod 22 is inserted into the bottom of the sliding rod 20 to lock it, thereby tightly connecting the base 1, the column 11 and the roof 13 into a whole. The rotating shaft 26 is equipped with a toothed disc 43 and a pawl 42 for one-way limiting. During locking, rotating the triangular bolt 28 counterclockwise causes the teeth of the toothed disc 43 to push open the pawl 42 and compress the torsion spring 44. After the torsion spring 44 returns to its original position, the pawl 42 continues to engage with the toothed disc 43 to achieve one-way self-locking, preventing the slide rod 20 from loosening and lifting due to external force, thus significantly improving the overall assembly stability of the enclosure. If the distribution box needs to be disassembled, first push the triangular bolt 28 axially, and then push the pawl 42 with the connecting rod 40 to separate it from the toothed disc 43 and release the limiting. Then, rotating the triangular bolt 28 clockwise will reset the guide block 21. By reversing the assembly process, all plates and rods can be quickly disassembled. The entire set of equipment adopts a modular and split component design, which occupies less storage and transportation space after disassembly, effectively reducing logistics and transportation costs. Outdoor on-site assembly and disassembly processes are simple and efficient.

[0056] Under normal ventilation and heat dissipation conditions, outside air flows upward from the enclosure vent 300, through the duct 30, and then into the enclosure through the ventilation slot 120 on the enclosure panel 12. Water splashed from the road cannot directly enter the ventilation slot 120, avoiding the risk of short circuits. The heat-conducting fins 32 inside the enclosure transfer internal heat to the duct 30. The flowing air, combined with heat evaporation, removes moisture from the air. A water collection box is located at the bottom of the duct 30 to collect condensed water droplets. The heat-conducting fins 32 extend into the water collection box, utilizing water to further enhance cooling. The drain outlet 302 of the water collection box is equipped with a rubber plug; removing the plug drains excess water. When outdoors… When the ambient air humidity exceeds the standard, the motor 36 drives the spur gear 35 to mesh with the rack 34, which in turn drives the two baffles 33 to slide in opposite directions to completely block the ventilation slot 120 and open the air outlet 301. The air circulates only between the ventilation opening 300 and the air outlet 301, preventing a large amount of high-humidity air from entering the box. At the same time, the heat-conducting plate 32 continuously exchanges heat to ensure heat dissipation performance. This comprehensively solves the defects of traditional outdoor power distribution boxes, such as high transportation costs, complicated assembly, and easy intrusion of rainwater and moisture, which can cause corrosion and short circuits of electrical components. It significantly improves the service life and operational safety of outdoor power distribution equipment.
