Description

Technical Field

[0001] This invention relates to the field of integrated power distribution equipment technology, specifically to a JP integrated power distribution box with a combined circuit adjustment structure. Background Technology

[0002] As is well known, JP integrated distribution boxes are outdoor integrated power distribution equipment suitable for low-voltage systems. They are widely used in urban and rural power grid renovation, industrial and mining power distribution scenarios, and residential areas. They integrate power distribution, metering, comprehensive protection, and reactive power compensation. Some intelligent models also support remote communication, data acquisition, and load monitoring. The internal structure adopts isolation structures such as metering room, switch room, and compensation room. They have short circuit, overload, leakage, lightning and overvoltage protection functions. They often adopt bottom-in and bottom-out wiring. Depending on the usage scenario, in cases where there are multiple points in the factory, multiple buildings in the park, loads along the road, and equipment points of multiple distributed transformers are scattered and far away, multiple small-capacity JP boxes are often used to ensure that the impact of power outages is small and maintenance only requires area power outage. However, in cases where all loads are near the distribution room or transformer and where space is limited, a single large-capacity JP box integrating multiple functions is mostly used.

[0003] When existing JP boxes are used in scenarios such as industrial parks and road projects, they are limited by installation space, messy wiring, and difficulty in maintenance zoning. We have found that JP boxes have a solidified structure and small opening space after long-term use, which limits the operating space during maintenance and makes expansion difficult. At the same time, the component mounting backplates are mostly directly fixed to the box or box bracket, which is also more troublesome when adjusting the circuit position. In addition, the space utilization rate needs to be improved. When using a single large-capacity box for centralized power distribution, the cabinet has problems such as single-point failure causing power outages throughout the area, excessively long cable runs, and high line loss. Ordinary small-capacity wall-mounted boxes have messy layouts.

[0004] Based on the problems mentioned above, we found that existing JP boxes are difficult to avoid these problems simultaneously. Therefore, we propose a JP integrated distribution box with a combined circuit adjustment structure that allows for independent power distribution in different zones, modular assembly, large maintenance space, flexible capacity expansion, easy wiring, and easy operation and maintenance. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a JP integrated distribution box with a combined circuit adjustment structure, which has the advantages of allowing independent power distribution in different zones, modular assembly, large maintenance space, flexible capacity expansion, easy wiring, and easy operation and maintenance.

[0007] (II) Technical Solution

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a JP integrated distribution box with a combined circuit adjustment structure, including a cooperating column, an end frame and an outer box. The outer box includes a fixed side plate and an opening and closing side plate. The top and bottom of the inner side of the fixed side plate are provided with module beams. The top of the bottom module beam is fixedly connected to two guide columns. The top of the guide columns is snapped into the top module beam. The top module beam is installed on the top of the inner side of the outer box by bolts. The outer side of the guide columns is movably connected to a movable beam. The outer side of the movable beam is movably connected to a depth frame. The outer side of both the movable beam and the depth frame is movably connected to a cable management module. The outer side of the fixed side plate is fixedly connected to an inlet plate.

[0009] The movable beam includes two sliding sleeves and a frame bar. The two sliding sleeves are slidably connected to the outside of two guide columns, and the two sliding sleeves are fixedly connected to both ends of the frame bar. The outside of the two sliding sleeves is provided with a safety pin and a fixing pin, respectively. The outside of the guide column is provided with a pin hole, and the safety pin passes through the sliding sleeve and is inserted into the pin hole.

[0010] Using the above technical solution, by setting matching columns, the enclosures are installed in a predetermined power distribution area. The required number of end brackets can be installed outside the matching columns as needed to complete the installation of the corresponding number of peripheral boxes. The fixed and hinged side plates of the peripheral box form the outer walls of the box. The top and bottom matching end brackets form a complete box. The module beams located inside the peripheral box cooperate with guide columns to facilitate the installation and support of the structure. After the top module beam is removed with bolts, the required number of movable beams can be fitted onto the two guide columns using two sliding sleeves, and then the top module beam is reinstalled and fixed to complete the installation of the movable beams. The movable beams can serve as mounting positions for component backplates or directly... The structure can be used to install equipment and junction boxes, and the depth frame can be installed on the outside of the movable beam. Component backplates and equipment can also be installed on the depth frame. The depth and tilt angle of the structure installation position inside the distribution box can be adjusted, or it can be installed on the movable beam and depth frame respectively to make full use of the internal space of the distribution box. The inlet plate is used to pass the lines into the inside of the distribution box, so as to facilitate the entry of the lines into the distribution box and assist in the wiring and tidying up with the wiring module. The frame of the movable beam serves as the main load-bearing position for installing component backplates or equipment. When the movable beam is moved to the required height, the safety pin can be inserted through the sliding sleeve and into the pin hole to prevent the movable beam from sliding down the guide column.

[0011] The present invention is further configured such that: the cable management module includes a first cable clamp and a second cable clamp, a guide rail is fixedly connected to the outer side of the first cable clamp, the inner side of the guide rail is slidably connected to the second cable clamp, a screw is threadedly connected to the side of the guide rail away from the second cable clamp, a push shell is rotatably connected to the side of the screw close to the second cable clamp, the push shell is fixedly connected to the second cable clamp on the side close to the second cable clamp, and a rotating shaft is rotatably connected to the side of the first cable clamp close to the support bar.

[0012] By adopting the above technical solution, by setting a first wire clamp in conjunction with a second wire clamp, when the cable management module is installed at the location where the line passes, the wire can be passed between the first wire clamp and the second wire clamp during the cable routing process. Then, the screw is rotated along the guide rail, and the push shell connected to it will push the second wire clamp closer to the wire and slightly press the wire to adapt to the number of strands or the radius of the wire to limit its position. The set rotating shaft can facilitate the rotation of the angle of the cable management module to match the cable routing position.

[0013] The present invention is further configured such that: the depth frame includes a double-layer frame and a corner frame, the bottom of the double-layer frame is provided with a horizontal groove, and the top of the corner frame is fixedly connected with a sliding pin, which is slidably connected to the inner side of the horizontal groove;

[0014] The angle bracket is provided with a clamping frame on the side away from the double-layer bracket, on the side of the double-layer bracket close to the bracket bar, and on the side of the rotating shaft close to the bracket bar. The clamping frame is engaged with the bracket bar on the side close to the bracket bar, and a threaded pin is threadedly connected to the inner side of the clamping frame.

[0015] Both the angle bracket and the double-layer bracket have short columns rotatably connected to their inner sides. The two short columns are fixedly connected to the clamping frame on the side closest to the clamping frame, and fastening bolts are threaded onto the inner side of the short columns.

[0016] By adopting the above technical solution, the clamping frame facilitates the installation of the double-layer frame, the angle bracket, and the pivot on the outside of the frame bar. During installation, the clamping frame can be inserted into the outside of the frame bar, and the position of the clamping frame can be fixed by tightening the threaded pin. After the double-layer frame and the angle bracket are installed on the outside of the frame bar, the installation angle of the outer structure of the double-layer frame can be adjusted by rotating the double-layer frame along the short column. When it is necessary to adjust the installation depth, the clamping frame can be slid along the frame bar to slide the double-layer frame to the required installation depth. At this time, rotating the angle bracket along the short column can make the sliding pin of the angle bracket slide along the transverse groove at the bottom of the double-layer frame to match the position of the double-layer frame for support. Then, the fastening bolts are tightened to fix the position of the depth frame.

[0017] The invention is further configured such that: the push shell includes an empty shell, the inner side of the empty shell is filled with oil, two sets of isolation channels are fixedly connected to the inner side of the empty shell, each of the isolation channels has a flow hole at both ends, a soft rubber sheet is slidably connected to the inner side of the isolation channel, a telescopic rod is fixedly connected to the side of the soft rubber sheet near the second wire clamp, the side of the telescopic rod near the second wire clamp is fixedly connected to the second wire clamp, a return spring is fixedly connected between the second wire clamp and the empty shell, and the outer side of the telescopic rod is slidably connected to the empty shell through a sealing element.

[0018] Using the above technical solution, by setting a push shell, when the screw pushes the second clamp through the push shell, the entire shell will move horizontally until the telescopic rod contacts the second clamp and the wire is under force. At this time, if you continue to push, you can feel the resistance of the return spring compression, which can avoid excessive pushing pressure that could damage the wire or affect the performance of the wire. When the external wire is pulled or the equipment moves and collided, causing the wire to potentially come loose from the joint, the wire will have a certain displacement relative to the first and second clamps. When the second clamp is under force and the return spring opens, the telescopic rod and soft rubber sheet connected to the second clamp will push the oil along the flow hole from the isolation channel to play a damping and buffering role, making it difficult for sudden short-term force to overcome the pressure of the second clamp and thus preventing loosening. When subjected to force for a long time, as the second clamp gradually opens, the wire can be pulled and moved to avoid the wire being continuously pulled and broken.

[0019] The present invention is further configured such that: the inlet plate includes an inner plate, a pass plate is fixedly connected to the inner side of the inner plate, a brush holder is fixedly connected to the inner side of the pass plate, and brush bristles are provided on the inner side of the brush holder.

[0020] By adopting the above technical solution, and by setting an inner plate in conjunction with a downward-sloping wire guide plate, water will not flow back into the box during rainy or snowy weather in the external environment. At the same time, after the wire passes through the brush and enters the box, the brush can intercept and prevent impurities in the external environment from entering the box with the airflow.

[0021] The present invention is further configured such that: the fixing pin includes a plug-in bracket and a limiting block; the limiting block is fixedly connected to the sliding sleeve on the side near the sliding sleeve; a limiting bolt is inserted into the inner side of the limiting block; the limiting bolt is fixedly connected to the plug-in bracket on the side near the plug-in bracket; the plug-in bracket passes through the sliding sleeve and is inserted into the pin hole; a tension spring is sleeved on the outer side of the limiting bolt; and the two ends of the tension spring are fixedly connected to the plug-in bracket and the limiting block, respectively.

[0022] Using the above technical solution, by setting a fixing pin, when the movable beam is moved vertically, the plug-in bracket can be pulled outward along the sliding sleeve. At this time, the tension spring is stretched and stored, and the limit bolt slides along the limit block to limit the movement. Then, the sliding action continues. After reaching the desired position, the plug-in bracket can be pulled back to its original position by the rebound of the tension spring, and the side of the plug-in bracket closest to the pin control is inserted into the pin control to complete the initial fixation. Finally, the safety pin is inserted to facilitate single-person operation.

[0023] The present invention is further configured such that: the mating column includes a column body and a base fixedly connected to the bottom of the column body, an end cap is inserted into the top of the column body, inclined tubes are fixedly connected to both sides and the rear side of the column body, an inner concave part is provided on the front side of the column body, and a wire opening cover is rotatably connected to the top of the inner side of the inner concave part through a torsion spring.

[0024] A slip ring is fitted on the outer side of the column.

[0025] Using the above technical solution, a base is set up to install the mating column in the required position and then fix it with bolts and other components. The end cap is set up to cover the top of the column to prevent water and impurities from the external environment from entering. When it is necessary to add additional slip rings to load more boxes, the end caps can be removed and slid into the slip rings from the top of the column. The set inclined tube can prevent water from the external environment from entering. At the same time, in conjunction with the heat dissipation holes of the bracket and the fixed side plate, hot air can be discharged directly into the inclined tube of the contact column through the heat dissipation holes to facilitate ventilation and heat dissipation. The wire opening cover connected by the torsion spring will rotate when the slip ring slides down and will reset when it stops contacting. Under normal circumstances, after the wire is led out of the box, it can be extended into the interior of the column through the bottom of the wire opening cover as needed, and extended downward to the slot at the bottom of the column for unified wiring.

[0026] The present invention is further configured such that: the slip ring includes two main ring portions, a mounting bracket is fixedly connected to the outer side of the main ring portion, adjacent mounting brackets are fixedly connected to a fixed side plate, heat dissipation holes are provided on the side of the fixed side plate near the mating column and on the inner side of the mounting bracket, and a mating bolt is threadedly connected to the inner side of the main ring portion, the mating bolt engaging with the inner recess.

[0027] By adopting the above technical solution, the main ring is set to be directly sleeved on the outside of the mating column. After being moved to the required position, the mating bolt can be screwed in so that it falls on the inside of the concave part to complete the fixation and limiting. The set bracket is used to directly connect with the end frame and the fixed side plate.

[0028] The present invention is further configured such that: the end frame includes a top frame and a bottom frame, and the top frame and the bottom frame are both fixedly connected to the fixed side plate on the side closest to the fixed side plate.

[0029] By adopting the above technical solution, a top frame and a bottom frame are set up to serve as the top and bottom of the entire box, respectively.

[0030] The present invention is further configured such that: the fixed side plate and the opening and closing side plate are rotatably connected by a hinge; a hook is fixedly connected to the outer side of the fixed side plate; a buckle is fixedly connected to the outer side of the opening and closing side plate; the buckle and the hook engage; and a sealing strip is fixedly connected to the adjacent side of the fixed side plate and the opening and closing side plate.

[0031] By adopting the above technical solution, the L-shaped fixed side plate and the opening and closing side plate connected by hinges are used instead of the semi-enclosed box body and box door mode. When unfolded, there is more operating space and flexibility. When closed, the sealing strip between the opening and closing side plate and the fixed side plate comes into contact with each other to avoid poor sealing at the joint. The opening and buckle can facilitate the fixing and unlocking of the position between the opening and closing side plate and the fixed side plate.

[0032] (III) Beneficial Effects

[0033] Compared with the prior art, the present invention provides a JP integrated distribution box with a combined circuit adjustment structure, which has the following advantages:

[0034] This JP integrated distribution box, featuring a combined circuit adjustment structure, is installed in a predetermined power distribution area via mating columns. It can also install a required number of end brackets outside the mating columns to complete the installation of a corresponding number of peripheral boxes. The fixed and hinged side plates of the peripheral box form the outer walls of the box body. The top and bottom mating end brackets form a complete box body. Modular beams located inside the peripheral box work with guide columns to facilitate structural installation and support. After the top modular beam is removed with bolts, the required number of movable beams can be fitted onto the two guide columns using two sliding sleeves, and then the top modular beam can be reinstalled and fixed to complete the installation of the movable beams. The movable beams can serve as mounting plates for components. The installation location can be either directly for mounting equipment and junction boxes, or the depth frame can be installed on the outside of the movable beam, with component backplates and equipment mounted on the depth frame. The depth and tilt angle of the structure installation position inside the distribution box can be adjusted, or it can be installed on the movable beam and depth frame respectively to make full use of the internal space of the distribution box. The inlet plate is used to pass the lines into the inside of the distribution box, so as to facilitate the line entry into the distribution box and assist in the wiring and organization with the wiring module. The frame bar of the movable beam serves as the main load-bearing position for mounting component backplates or equipment. When the movable beam is moved to the required height, the safety pin can be inserted through the sliding sleeve and into the pin hole to prevent the movable beam from sliding down the guide column naturally.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] Please see Figure 1-10 A JP integrated distribution box with a combined circuit adjustment structure includes a cooperating column 1, an end frame 2, and an outer box 3. The outer box 3 includes a fixed side plate 31 and an opening and closing side plate 32. The top and bottom of the inner side of the fixed side plate 31 are provided with module beams 33. The top of the bottom module beam 33 is fixedly connected to two guide columns 34. The top of the guide columns 34 is snapped into the top module beam 33. The top module beam 33 is installed on the top of the inner side of the outer box 3 by bolts. The outer side of the guide columns 34 is movably connected to a movable beam 35. The outer side of the movable beam 35 is movably connected to a depth frame 36. The outer sides of both the movable beam 35 and the depth frame 36 are movably connected to a cable management module 37. The outer side of the fixed side plate 31 is fixedly connected to an inlet plate 38.

[0049] The movable beam 35 includes two sliding sleeves 351 and a support bar 352. The two sliding sleeves 351 are slidably connected to the outside of the two guide posts 34 respectively. The two sliding sleeves 351 are fixedly connected to both ends of the support bar 352. The outside of the two sliding sleeves 351 is provided with a safety pin 353 and a fixing pin 354 respectively. The outside of the guide post 34 is provided with a pin hole. The safety pin 353 passes through the sliding sleeve 351 and is inserted into the pin hole.

[0050] By setting up mating columns 1, installed in a predetermined power distribution area, and by installing the required number of end brackets 2 outside the mating columns 1 as needed, the corresponding number of peripheral boxes 3 can be installed. The fixed side plate 31 and the opening / closing side plate 32 of the peripheral box 3 form the outer walls of the box. The top and bottom mating end brackets 2 form a complete box. The module beam 33 located inside the peripheral box 3, mating with guide columns 34, facilitates the installation and support of the structure. After removing the top module beam 33 with bolts, the required number of movable beams 35 can be fitted onto the two guide columns 34 using two sliding sleeves 351, and then the top module beam 33 can be reinstalled and fixed to complete the installation of the movable beams 35. The movable beams 35 can serve as mounting positions for component backplates or directly mount equipment. The structure includes junction boxes and other components. The depth frame 36 can be installed on the outside of the movable beam 35, and the component backplate and equipment can be installed on the depth frame 36. The depth and tilt angle of the structure installation position inside the distribution box can be adjusted, or it can be installed on the movable beam 35 and the depth frame 36 respectively to make full use of the internal space of the distribution box. The inlet plate 38 is used to pass the line into the inside of the distribution box, so as to facilitate the line to enter the distribution box and assist in the wiring module 37 for wiring organization. The frame bar 352 of the movable beam 35 serves as the main load-bearing position for installing the component backplate or equipment. When the movable beam 35 is moved to the required height, the safety pin 353 can pass through the sliding sleeve 351 and be inserted into the pin hole to prevent the movable beam 35 from sliding down the guide post 34 naturally.

[0051] The cable management module 37 includes a first cable clamp 371 and a second cable clamp 372. A guide rail 373 is fixedly connected to the outer side of the first cable clamp 371, and the inner side of the guide rail 373 is slidably connected to the second cable clamp 372. A screw 374 is threadedly connected to the side of the guide rail 373 away from the second cable clamp 372. A push shell 375 is rotatably connected to the side of the screw 374 near the second cable clamp 372. The push shell 375 is fixedly connected to the second cable clamp 372 on the side near the first cable clamp 371. A rotating shaft 376 is rotatably connected to the side of the first cable clamp 371 near the support bar 352. By setting the first cable clamp 371 and the second cable clamp 372 together, when the cable management module 37 is installed at the location where the cable passes, the wires can pass through the first cable clamp 371 and the second cable clamp 372 during the cable routing process. Between, the screw 374 is rotated along the guide rail 373, and the pusher 375 connected to it pushes the second wire clamp 372 closer to the wire and slightly presses the wire to accommodate the number of strands or the wire radius to limit its position. The rotating shaft 376 can easily rotate the angle of the wire management module 37 to match the wire routing position. The depth frame 36 includes a double-layer frame 361 and a corner frame 362. The bottom of the double-layer frame 361 has a horizontal groove, and the top of the corner frame 362 is fixedly connected to a sliding pin, which is slidably connected to the inner side of the horizontal groove. The corner frame 362 is provided with a clamping frame 363 on the side away from the double-layer frame 361, the side of the double-layer frame 361 near the frame bar 352, and the side of the rotating shaft 376 near the frame bar 352. The side of the clamping frame 363 near the frame bar 352 and the frame bar 352 are all provided with clamping frames 363. 52 is snap-fitted together. A threaded pin 364 is threaded onto the inner side of the clamping frame 363. Short columns 365 are rotatably connected to the inner sides of both the angle bracket 362 and the double-layer frame 361. The two short columns 365 are fixedly connected to the clamping frame 363 on the side closest to it. Fastening bolts 366 are threaded onto the inner side of the short columns 365. By setting the clamping frame 363, it is easy to install the double-layer frame 361, the angle bracket 362, and the rotating shaft 376 on the outside of the frame bar 352. During installation, the clamping frame 363 can be inserted into the outside of the frame bar 352, and the position of the clamping frame 363 can be fixed by tightening the threaded pin 364. After the double-layer frame 361 and the angle bracket 362 are respectively installed on the outside of the frame bar 352, the double-layer frame 361 can be adjusted by rotating it along the short columns 365. The installation angle of the outer structure 361 can be adjusted as needed by sliding the clamp 363 along the frame bar 352 to slide the double-layer frame 361 to the required installation depth. At this time, rotating the angle bracket 362 along the short column 365 can allow the sliding pin of the angle bracket 362 to slide along the transverse groove at the bottom of the double-layer frame 361 to match the position of the double-layer frame 361 for support. Then, tighten the fastening bolt 366 to complete the position fixation of the depth frame 36. The push shell 375 includes an empty shell 3751, the inner side of which is filled with oil. Two sets of isolation channels 3752 are fixedly connected to the inner side of the empty shell 3751. Both ends of the isolation channels 3752 are provided with flow holes 3753. A soft rubber sheet 3756 is slidably connected to the inner side of the isolation channels 3752.A telescopic rod 3754 is fixedly connected to the side of the soft rubber sheet 3756 near the second wire clamp 372. The side of the telescopic rod 3754 near the second wire clamp 372 is fixedly connected to the second wire clamp 372. A return spring 3755 is fixedly connected between the second wire clamp 372 and the empty shell 3751. The outer side of the telescopic rod 3754 is slidably connected to the empty shell 3751 through a seal. By setting the push shell 375, when the screw 374 pushes the second wire clamp 372 through the push shell 375, the entire empty shell 3751 will move horizontally until the telescopic rod 3754 contacts the second wire clamp 372 and the wire is under force. At this time, if you continue to push, you can feel the resistance of the compression of the return spring 3755, which can avoid excessive pushing force that may damage the wire or cause the wire to be compressed. To improve performance, when the external wire is pulled or the equipment moves and collides, causing the wire to potentially come loose from the connector, the wire will have a certain displacement relative to the first clamp 371 and the second clamp 372. When the second clamp 372 is pressed against the return spring 3755 and opens, the telescopic rod 3754 and the soft rubber sheet 3756 connected to the second clamp 372 will push the oil along the flow hole 3753 from the isolation channel 3752 to achieve a damping and buffering effect, making it difficult for sudden short-term force to overcome the pressure of the second clamp 372, thus preventing loosening. However, under long-term force, as the second clamp 372 gradually opens, the wire can be pulled and moved to prevent the wire from being continuously pulled and broken. The inlet plate 38 includes an inner plate 381, the inner... A cable guide plate 382 is fixedly connected to the inner side of plate 381. A brush holder 383 is fixedly connected to the inner side of cable guide plate 382. The inner side of brush holder 383 is provided with bristles. By setting the inner plate 381 in conjunction with the downward-sloping cable guide plate 382, ​​water will not flow back into the cabinet during rain or snow in the external environment. At the same time, after the wire passes through the brush and enters the cabinet, the brush can intercept and prevent impurities in the external environment from entering the cabinet with the airflow. The fixing pin 354 includes a plug-in bracket 3541 and a limiting block 3542. The side of the limiting block 3542 near the sliding sleeve 351 is fixedly connected to the sliding sleeve 351. A limiting bolt 3543 is inserted into the inner side of the limiting block 3542. The side of the limiting bolt 3543 near the plug-in bracket 3541 is fixedly connected to the plug-in bracket 3541. The connector 3541 passes through the sliding sleeve 351 and is inserted into the pin hole. A tension spring 3544 is sleeved on the outside of the limiting bolt 3543. The two ends of the tension spring 3544 are fixedly connected to the connector 3541 and the limiting block 3542, respectively. By setting the fixing pin 354, when the movable beam 35 is moved vertically, the connector 3541 can be pulled outward along the sliding sleeve 351. At this time, the tension spring 3544 is stretched and stored. The limiting bolt 3543 slides along the limiting block 3542 to limit the movement. Then, the sliding action continues. After reaching the desired position, the rebound of the tension spring 3544 can pull the connector 3541 back to its original position, and the side of the connector 3541 closest to the pin control is inserted into the pin control to complete the initial fixation. Finally, the safety pin 353 is inserted to facilitate single-person operation.The fixed side plate 31 and the opening / closing side plate 32 are rotatably connected by a hinge. A hook is fixedly connected to the outer side of the fixed side plate 31, and a buckle is fixedly connected to the outer side of the opening / closing side plate 32. The buckle and hook engage. Sealing strips 5 are fixedly connected to adjacent sides of both the fixed side plate 31 and the opening / closing side plate 32. The L-shaped fixed side plate 31 and opening / closing side plate 32, connected by a hinge, replace the semi-enclosed box and door design, providing greater operating space and flexibility when unfolded. When closed, the sealing strips 5 between the opening / closing side plate 32 and the fixed side plate 31 contact each other to prevent poor sealing at the joint. The buckle at the opening facilitates fixing and unlocking the position of the opening / closing side plate 32 and the fixed side plate 31.

[0052] Working principle of this embodiment: The distribution box adopts a hinged design between the fixed side plate 31 and the opening side plate 32, which can be opened at a large angle to expand the maintenance and operation space. After closing, the box is sealed with buckles and sealing strip 5 to achieve waterproof and dustproof sealing of the box joints. After disassembling the top module beam 33, multiple sets of movable beams 35 can be assembled on the outside of the guide column 34 via the sliding sleeve 351. The frame assembly is completed by resetting the module beam 33. The movable beams 35 can slide up and down along the guide column 34. The fixed pin 354 with tension spring 3544 achieves self-reset initial positioning, and then the safety pin 353 locks it a second time, so that the installation height of the components can be flexibly adjusted. The depth frame 36 is clamped to the frame bar 352 of the movable beam 35 by the clamp frame 363. It can slide laterally to adjust the installation depth, and the double-layer frame 361 and the angle frame 362 can rotate around the short column 365 to adjust the tilt angle of the component installation. The threaded pin 364 and fastening bolt 366 are fixed in place, making full use of the three-dimensional space inside the box. The cable management module 37 can be rotated by the pivot 376 to adapt to different cable routing angles. Rotating the screw 374 can push the second wire clamp 372 to slide along the guide rail 373, adaptively clamping wires of different diameters and strands. The push shell 375 is filled with oil and, together with the isolation channel 3752, soft rubber sheet 3756, telescopic rod 3754 and return spring 3755, forms a damping buffer structure, which can not only avoid damage to the wires due to excessive clamping pressure, but also buffer the instantaneous pulling impact of the line to prevent the joint from loosening. Under long-term stress, it can also slowly release displacement to prevent the wire from being pulled off. The external line is introduced into the box through the inclined cable guide plate 382 of the inlet plate 38. The inclined structure can prevent rain and snow from flowing back in. The bristles on the brush holder 383 can intercept external dust and debris, ensuring that the inside of the box is clean and dry.

[0053] Example 2

[0054] refer to Figure 1-3A JP integrated distribution box with a combined circuit adjustment structure also includes a mating column 1, wherein the mating column 1 includes a column body 11 and a base 12 fixedly connected to the bottom of the column body 11. An end cap 13 is inserted into the top of the column body 11. Inclined tubes 14 are fixedly connected to both sides and the rear side of the column body 11. A concave portion 15 is provided on the front side of the column body 11. A wire opening cover 16 is rotatably connected to the top of the inner side of the concave portion 15 via a torsion spring. A slip ring 4 is sleeved on the outer side of the column body 11. The base 12 is used to install the mating column 1 in the required installation position and then install it with bolts or other fixing components. The end cap 13 is used to shield the top of the column body 11 to prevent water and impurities from the external environment from entering. When additional... When loading more enclosures, the end cap 13 can be removed and slid into the slip ring 4 from the top of the top column 11. The inclined tube 14 can prevent water from entering from the external environment. At the same time, in conjunction with the heat dissipation holes of the bracket 42 and the fixed side plate 31, hot air can be discharged directly into the inclined tube 14 of the column 11 through the heat dissipation holes for ventilation and heat dissipation. The wire opening cover 16 connected by the torsion spring will rotate when the slip ring 4 slides down and will reset when it stops contacting. Under normal circumstances, after the wire is led out of the enclosure, it can be inserted into the interior of the column 11 through the bottom of the wire opening cover 16 as needed, and extended downward to the slot at the bottom of the column 11 for unified wiring.

[0055] The slip ring 4 includes two main ring parts 41. A mounting bracket 42 is fixedly connected to the outer side of the main ring part 41. Adjacent mounting brackets 42 are fixedly connected to the fixed side plate 31. Heat dissipation holes are provided on the side of the fixed side plate 31 near the mating column 1 and on the inner side of the mounting bracket 42. A mating bolt 43 is threadedly connected to the inner side of the main ring part 41. The mating bolt 43 is engaged with the inner recess 15. The main ring part 41 is designed to be directly fitted onto the outer side of the mating column 1. After moving to the desired position, the mating bolt 43 can be screwed in so that it falls into the inner side of the inner recess 15 to complete the fixing and limiting. The mounting bracket 42 is designed to be directly connected to the end frame 2 and the fixed side plate 31. The end frame 2 includes a top frame 21 and a bottom frame 22. The top frame 21 and the bottom frame 22 are fixedly connected to the fixed side plate 31 on the side near the fixed side plate 31. The top frame 21 and the bottom frame 22 serve as the top and bottom of the entire box body, respectively.

[0056] The working principle of this embodiment is as follows: The mounting column 1 serves as the base for the entire distribution box. The column 1 is fixed to the ground via the bottom base 12. The top-mounted end cap 13 protects against rainwater and impurities from entering the column 11. The inclined pipes 14 on both sides and the rear of the column 11 not only drain accumulated water to prevent seepage but also serve as ventilation and heat dissipation channels. Removing the end cap 13 allows the slip ring 4 to be inserted from the top of the column 11. The slip ring 4 can slide up and down along the column 11 to adjust the installation level. Screwing in the mating bolt 43 locks the slip ring 4 into the recessed part 15, thus positioning and locking it. The outer bracket 42 of the slip ring 4 is connected to the distribution box... The fixed side plate 31 and the end frame 2 are fixedly connected to each other, so that multiple distribution boxes can be mounted on a single cooperating column 1 in layers. The number of boxes can be increased or decreased as needed to complete flexible capacity expansion and independent power distribution in different areas. The heat dissipation holes on the fixed side plate 31 and the mounting frame 42 are interconnected with the inclined tube 14 of the column 11. The hot air inside the box can flow into the inclined tube 14 through the heat dissipation holes through natural convection and be discharged outward, continuously ventilating and cooling the components inside the box. At the same time, the wires led out of the box can be stored in the inside of the column 11 through the wire opening cover 16 connected by the torsion spring, and then uniformly led out from the bottom of the column 11 to achieve centralized and neat arrangement of the wires of multiple boxes.
