Description

Technical Field

[0001] This invention relates to the field of ring main unit technology, and in particular to a modular, fast wiring type integrated primary and secondary ring main unit. Background Technology

[0002] The integrated primary and secondary ring main unit (DTU) serves as the core switching equipment for urban power distribution networks, industrial parks, and residential power distribution networks. It integrates primary high-voltage switch components, instrument transformers, and secondary DTU measurement, control, protection, and communication units, making it a key piece of equipment for achieving power distribution automation, rapid fault isolation, and load transfer.

[0003] The current mainstream design of ring main units has certain limitations, with their form and structure being relatively fixed. Typically, the entire enclosure is assembled in the factory workshop and then transported to the site as a single unit for deployment. This integrated prefabrication model significantly increases the difficulty of transportation, resulting in high logistics costs. Furthermore, during on-site installation, its flexibility in adapting to specific environmental conditions is poor, making it difficult to easily adjust according to site space and cable routing. In addition, anti-condensation mechanisms designed to address potential moisture issues inside the enclosure are usually pre-installed within the ring main unit's internal space. This pre-installation method, to some extent, occupies valuable internal layout space, affecting the arrangement of other electrical equipment or cables, thereby reducing the overall utilization efficiency of the ring main unit's internal space.

[0004] A modular primary and secondary integrated ring main unit, with announcement number CN121965322B, includes a high-voltage switchgear, a gas-liquid circulation switchgear, a low-voltage switchgear, a temperature control module, and a top cover. The temperature control module includes an outer cover plate, heat pipes, a condenser plate, a connecting plate, a flame-retardant and heat-insulating layer, and an insulating layer. An assembly groove is provided on the inner wall of the top cover, and an arched plate is fitted inside the top cover via the assembly groove. Multiple filter media slots are provided on the bottom surface of the arched plate, and a gas guide pipe is provided on the top of the arched plate, connecting the multiple filter media slots. Filter media is installed in the filter media slots. This invention adopts a modular design, allowing the high-voltage switchgear, gas-liquid circulation switchgear, low-voltage switchgear, temperature control module, and top cover to be independently packaged, reducing transportation space occupancy and lowering the difficulty and cost of logistics transportation. The temperature control module is integrated and assembled on the back side of the high-voltage switchgear, without occupying internal layout space within the cabinet.

[0005] The aforementioned technical components can effectively utilize the components inside the enclosure, but they are not convenient for the maintenance of the cabinet inside the enclosure and cannot effectively guarantee the stability of the cabinet cables, so improvements are needed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, fast-wiring type primary and secondary integrated ring network box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A modular, fast-wiring type integrated primary and secondary ring network box includes a box assembly, a support plate is slidably installed inside the box assembly, an integrated cabinet assembly is detachably connected to the upper end of the support plate, and a cable clamping mechanism is installed at the rear end of the support plate, the cable clamping mechanism being connected to the integrated cabinet assembly. A moving mechanism is installed at the lower end of the bearing plate. The moving mechanism is equipped with a synchronous shaft and multiple moving wheels. The moving wheels are located at the lower end of the housing assembly. Both ends of the housing assembly are equipped with foot pedal mechanisms, and the synchronous shaft is connected to the two foot pedal mechanisms; The foot pedal mechanism is equipped with a fixed straight rack and a foot pedal component. The fixed straight rack and the lower end of the bearing plate are fixedly connected. Positioning plates are fixed on both sides of the lower end of the bearing plate. The two foot pedal components are respectively engaged with the two positioning plates.

[0008] Compared with existing technologies, this invention can simultaneously unlock the horizontal and vertical locks of the enclosure with a simple foot pedal action, allowing the internal core cabinet to slide out like a drawer, greatly facilitating maintenance. During the process of pushing the cabinet back, the linkage system can automatically trigger the cable clamping mechanism, which can firmly lock the cables without manual intervention. The automated design that integrates the three functions of moving, unlocking, and fixing significantly improves installation and maintenance efficiency, reduces transportation costs through modular structure, and optimizes the space utilization inside the enclosure.

[0009] Preferably, the cable clamping mechanism includes an opening at the rear end of the support plate, and cable clamping components are slidably installed on opposite sidewalls within the opening; The rear end of the bearing plate is equipped with a reverse drive mechanism, which has two L-shaped teeth that are fixedly connected to two cable clamps respectively. The reverse drive mechanism is provided with an abutting straight rack, which abuts against the rear end of the housing assembly.

[0010] Furthermore, the reverse drive mechanism can adjust the position of the cable clamping components according to the position of the supporting plate in order to control the clamping effect on the cable.

[0011] Preferably, the reverse drive mechanism includes a first linkage gear component rotatably sleeved on the support plate, and a second linkage gear component is fixed to the upper end of the first linkage gear component; The abutting spur rack is slidably mounted on the bearing plate, and the abutting spur rack meshes with the first linkage gear. The two L-shaped teeth mesh with the two sides of the second linkage gear respectively.

[0012] Furthermore, when the supporting plate moves into the housing assembly, it causes the abutting rack and the rear end of the housing assembly to come into contact, which in turn causes the abutting rack to drive the first linkage gear to rotate. That is, the first linkage gear can drive the second linkage gear to rotate. The rotation of the second linkage gear can cause the L-shaped gear condition to move, which in turn can drive the cable clamp to move. The movement of the cable clamp can control whether the cable is clamped or released.

[0013] Preferably, slide rails are detachably connected to opposite side walls within the housing assembly, and the two ends of the bearing plate are slidably installed within the two slide rails respectively.

[0014] Furthermore, the components are easy to disassemble and install, and can ensure the smooth movement of the supporting plates.

[0015] Preferably, the moving mechanism includes two support frames fixed on both sides of the lower end of the bearing plate, a moving frame fixed at the lower end of the support frame, two notches opened at the lower end of the box assembly, the two moving frames respectively passing through the two notches, and multiple moving wheels respectively installed at the lower end of the two moving frames; The lower end of the bearing plate is provided with a synchronization plate, which is fixed to the bottom of the housing assembly. A separation mechanism is installed on the synchronization plate, and the separation mechanism is provided with two straight racks. A gear is fixed to the lower end of the bearing plate, and the two straight racks are respectively meshed on both sides of the gear. The separation mechanism includes a pusher that is slidably installed at the lower end of the synchronization plate. An eccentric wheel is rotatably fitted inside the housing assembly, and a synchronous shaft is disposed through the eccentric wheel. The eccentric wheel and the pusher abut against each other. A through opening is provided inside the support frame, and a sliding block is slidably installed inside the through opening. Two sliding blocks pass through both ends of the synchronous shaft.

[0016] Furthermore, the support frame and the load-bearing plate are fixedly connected, and the movable frame is fixedly connected to the support frame. In actual operation, in order to ensure the stability of the support, three movable wheels can be installed at the lower end of each movable frame, that is, movable wheels are set on both sides and the middle of the lower end of the movable frame, so as to effectively ensure the support strength and facilitate the smooth movement of the integrated cabinet components and the load-bearing plate.

[0017] Preferably, the separation mechanism includes a limiting track fixed to one side of the synchronization plate, and two sliding members are slidably mounted on the limiting track, with two straight racks respectively fixedly connected to the two sliding members; The lower end of the sliding member is rotatably connected to a slanted push rod, and the lower ends of the two slanted push rods are respectively rotatably connected to both sides of the pushing member; A return spring is fixed between the two inclined push rods.

[0018] Furthermore, the deflection of the eccentric wheel can push the pusher to move towards the synchronous plate, which in turn pushes the inclined push rod to move the sliding member on the limiting track. When the pusher rises, it will cause the two sliding members to separate, and the two sliding members can drive the two straight racks fixed to them to separate, and the two straight racks will no longer mesh with the bearing plate.

[0019] Preferably, the foot pedal mechanism includes two tension springs fixed on both sides inside the housing assembly, the lower ends of the two tension springs being fixedly connected to two foot pedals respectively, and the two foot pedals being slidably mounted on opposite side walls inside the housing assembly. Both sides of the housing assembly are fixed with support frames, and inclined plate pieces are rotatably sleeved inside the support frames. The two ends of the synchronous shaft piece pass through the two support frames respectively and are fixedly connected to the two inclined plate pieces. The upper ends of the two inclined plate components are slidably installed on the lower ends of the two foot pedal components respectively; a lifting rod is slidably installed at the bottom of each of the two box components, and a linkage rod is fixed on the lifting rod. A moving opening is opened on the inclined plate component, and a support block is slidably installed in the moving opening. One end of the two linkage rods is rotatably sleeved on the two support blocks. Two fixed straight racks are fixed on both sides of the lower end of the bearing plate, and two lifting straight racks are fixed on the upper end of the two lifting rods. The two lifting straight racks mesh with the two fixed straight racks respectively.

[0020] Furthermore, the operator can step on the foot pedal to lower it, thereby driving the corresponding components to operate. At the same time, the tension spring will be stretched, allowing the support plate to move. When the external force disappears, the tension spring can pull the foot pedal upward, causing the corresponding components to reset and the support plate to be fixed.

[0021] Preferably, the synchronous shaft and the inclined plate are coaxially arranged.

[0022] Furthermore, the coaxial arrangement enables the inclined plate and the synchronous shaft to rotate synchronously. That is, when the foot pedal is stepped on, the inclined plate and the synchronous shaft rotate synchronously. The synchronous shaft drives the eccentric wheel to rotate, and the eccentrically positioned eccentric wheel drives the pusher to lift and lower.

[0023] Preferably, the diameter of the second linkage gear is larger than the diameter of the first linkage gear.

[0024] Furthermore, by changing the diameter, when the spur rack and the rear end of the housing assembly come into contact, the spur rack can drive the first linkage gear to rotate, and the first linkage gear can drive the second linkage gear to rotate, thereby increasing the movement distance of the L-shaped gear.

[0025] Preferably, adjustable screw fasteners are installed at the four lower corners of the housing assembly.

[0026] Furthermore, the adjustable screw fastener adopts a rotatable screw component, and a pad component is sleeved on the lower end of the screw component. By rotating the screw component, the distance between the pad component and the bottom of the housing assembly can be changed to effectively ensure the support strength. At the same time, the distance between the housing assembly and the pad can be adjusted to ensure the stability of the housing assembly.

[0027] The beneficial effects of this invention are: 1. Modular design reduces transportation and installation costs: This invention adopts a modular design, installing the core integrated cabinet components on sliding load-bearing plates; this design breaks the traditional integrated and indivisible form of ring network boxes, allowing the equipment to be transported in parts, significantly reducing the difficulty and cost of logistics transportation; at the same time, during on-site installation, it can be flexibly adjusted according to the specific environment, making it more adaptable; 2. Foot-operated linkage unlocking, convenient and efficient maintenance: By stepping on the foot pedal, the entire locking system can be controlled in a coordinated manner; this action can simultaneously release the separation between the lifting rack and the fixed rack, as well as the separation between the rack and the gear assembly, allowing the internal support plate and its integrated cabinet components to be easily pulled out like a drawer; this greatly facilitates the installation, wiring, and subsequent maintenance of the equipment, eliminating the need for complicated tools and operations; 3. Automatic cable clamping enhances stability and efficiency: The equipment incorporates a clever automatic cable clamping mechanism. When the support plate is pushed back into the housing assembly, its abutting rack contacts the inner wall of the housing assembly, automatically triggering the reverse drive mechanism to clamp the cables on both sides; conversely, it automatically releases when pulled out. This design not only ensures the long-term stability of the cable connection but also eliminates the need for manual cable securing, improving wiring efficiency. 4. Optimize internal space and improve space utilization: Due to the adoption of a pull-out modular design, functional components such as cable clamps and component fixation can be cleverly arranged in non-core areas such as under the load-bearing plates or on the side walls of the enclosure, instead of being pre-fixed inside the enclosure and occupying valuable space as in traditional designs. This makes the internal layout of the enclosure more flexible, leaving more space for the arrangement of primary and secondary equipment, thereby improving the overall space utilization efficiency.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1-9 A modular, rapid cabling type primary and secondary integrated ring network box includes a box assembly 1. A support plate 11 is slidably installed inside the box assembly 1. An integrated cabinet assembly 5 is detachably connected to the upper end of the support plate 11. The integrated cabinet assembly 5 houses the components required for the operation of the primary and secondary integrated ring network box. A cable clamping mechanism is installed at the rear end of the support plate 11 and is connected to the integrated cabinet assembly 5. The cable clamping mechanism can release the cable passing through the support plate 11 when the support plate 11 is movable, and effectively ensure the stability of the cable after the support plate 11 moves into the box assembly 1. A moving mechanism is installed at the lower end of the support plate 11. The moving mechanism is equipped with a synchronous shaft 38 and multiple moving wheels 7. The moving wheels 7 are located at the lower end of the housing assembly 1. The moving mechanism facilitates the movement of the support plate 11 and helps to support the support plate 11. Both ends of the housing assembly 1 are equipped with foot pedal mechanisms, and the synchronous shaft 38 is connected to the two foot pedal mechanisms. The operation of the foot pedal mechanisms will cause the synchronous shaft 38 to rotate synchronously, so as to drive the corresponding components to operate, thereby realizing the fixation or movement of the bearing plate 11. The foot pedal mechanism is equipped with a fixed rack 21 and a foot pedal 26. The fixed rack 21 is fixedly connected to the lower end of the bearing plate 11. Positioning plates 25 are fixed on both sides of the lower end of the bearing plate 11. The two foot pedals 26 are respectively engaged with the two positioning plates 25. The operation of the foot pedal mechanism can control the position of the foot pedal 26. The position adjustment of the foot pedal 26 can control the positional relationship between the lifting rack 22 and the fixed rack 21, and also adjust the positional relationship between the foot pedal 26 and the positioning plates 25, so that the bearing plate 11 can be moved or fixed. In actual operation, multiple notches can be set at equal intervals at the lower end of the positioning plate 25, and a locking block can be fixed at the upper end of the foot pedal 26. The connection can be strengthened by inserting the locking block and the notches.

[0032] In this embodiment, the cable clamping mechanism includes an opening 9 at the rear end of the supporting plate 11, and cable clamping members 8 are slidably installed on opposite sidewalls within the opening 9; this ensures the stability of the movement of the cable clamping members 8. A reverse drive mechanism is installed at the rear end of the supporting plate 11, and the reverse drive mechanism has two L-shaped toothed conditions 32, which are respectively fixedly connected to two cable clamping members 8. The reverse drive mechanism has an abutting straight toothed rack 29, which abuts against the rear end of the housing assembly 1. The position of the cable clamping members 8 can be adjusted according to the position of the supporting plate 11 through the reverse drive mechanism, so as to control the clamping effect on the cable.

[0033] In this embodiment, the reverse drive mechanism includes a first linkage gear 31 rotatably sleeved on the support plate 11, and a second linkage gear 30 fixed to the upper end of the first linkage gear 31; an abutting rack 29 is slidably mounted on the support plate 11, the abutting rack 29 and the first linkage gear 31 mesh, and two L-shaped toothed conditions 32 mesh on both sides of the second linkage gear 30 respectively; when the support plate 11 moves toward the housing assembly 1, the abutting rack 29 and the rear end of the housing assembly 1 abut, and the abutting rack 29 pushes the first linkage gear 31 to rotate, that is, the first linkage gear 31 can drive the second linkage gear 30 to rotate, and the rotation of the second linkage gear 30 can cause the L-shaped toothed conditions 32 to move, and the L-shaped toothed conditions 32 can drive the cable clamp 8 to move, and the movement of the cable clamp 8 can control whether the cable is clamped or released.

[0034] In this embodiment, slide rails 10 are detachably connected to opposite side walls inside the housing assembly 1, and the two ends of the bearing plate 11 are slidably installed in the two slide rails 10 respectively; this facilitates disassembly and installation and ensures the smooth movement of the bearing plate 11.

[0035] In this embodiment, the moving mechanism includes two support frames 6 fixed on both sides of the lower end of the bearing plate 11. A moving frame 3 is fixed at the lower end of the support frame 6. Two notches 4 are opened at the lower end of the housing assembly 1. The two moving frames 3 are respectively installed through the two notches 4. Multiple moving wheels 7 are respectively installed at the lower ends of the two moving frames 3. The support frame 6 and the bearing plate 11 are fixedly connected, and the moving frame 3 and the support frame 6 are also fixedly connected. In actual operation, in order to ensure the stability of the support, three moving wheels 7 can be installed at the lower end of each moving frame 3. That is, moving wheels 7 are provided on both sides and in the middle of the lower end of the moving frame 3, so as to effectively ensure the support force and facilitate the smooth movement of the fusion cabinet assembly 5 and the bearing plate 11.

[0036] The lower end of the supporting plate 11 is provided with a synchronization plate 37, which is fixed to the bottom of the housing assembly 1. A separation mechanism is installed on the synchronization plate 37, which is provided with two straight racks 16. A gear 17 is fixed to the lower end of the supporting plate 11, and the two straight racks 16 are respectively meshed on both sides of the gear 17. The separation mechanism includes a pusher 19 that is slidably installed at the lower end of the synchronization plate 37. The synchronization plate 37 can be arranged in an L-shape, and the vertical end of the synchronization plate 37 is located at the rear end of the housing assembly 1 and is fixedly connected to the rear end of the housing assembly 1. An eccentric wheel 20 is rotatably fitted inside the housing assembly 1, and a synchronous shaft 38 is disposed through the eccentric wheel 20. The eccentric wheel 20 and the pusher 19 abut against each other. A through-hole 34 is provided in the support frame 6, and a sliding block 33 is slidably installed in the through-hole 34. Two sliding blocks 33 pass through both ends of the synchronous shaft 38. In actual operation, when the synchronous shaft 38 rotates, it can drive the eccentric wheel 20 to deflect. The eccentric setting of the eccentric wheel 20 can make the distance between the eccentric wheel 20 and the synchronous shaft 38 different, so that the distance between the pusher 19 and the synchronous plate 37 can change. Moreover, in actual operation, the eccentric wheel 20 is rotatably sleeved with a ring, which makes it easier to lift and lower the pusher 19. When the bearing plate 11 moves, the ring on the eccentric wheel 20 can rotate, which can reduce the moving resistance of the bearing plate 11. Furthermore, when the bearing plate 11 moves the support frame 6, the synchronous shaft 38 enables the sliding block 33 to move within the through opening 34, that is, the positions of the sliding block 33 and the synchronous shaft 38 are defined.

[0037] In this embodiment, the separation mechanism includes a limiting track 14 fixed to one side of the synchronization plate 37. Two sliding members 13 are slidably mounted on the limiting track 14, and two racks 16 are fixedly connected to the two sliding members 13 respectively. The deflection of the eccentric wheel 20 can push the pusher 19 to move towards the synchronization plate 37, which can push the inclined push rod 15 to make the sliding members 13 move on the limiting track 14. When the pusher 19 rises, it will cause the two sliding members 13 to separate. The two sliding members 13 can drive the two racks 16 fixed to them to separate, and the two racks 16 will no longer mesh with the bearing plate 11. The lower end of the sliding member 13 is rotatably connected to a slanted push rod 15, and the lower ends of the two slanted push rods 15 are respectively rotatably connected to both sides of the push member 19. The angle between the two slanted push rods 15 can be controlled by the lifting and lowering of the push member 19. When the push member 19 rises, the angle between the two slanted push rods 15 increases, and when the push member 19 falls, the angle between the two slanted push rods 15 decreases. A return spring 18 is fixed between the two slanted push rods 15. The return spring 18 can adapt to the lifting and lowering of the push member 19 and the deflection of the slanted push rods 15. When the external force disappears, the slanted push rods 15 can be reset.

[0038] In this embodiment, the foot pedal mechanism includes two tension springs 12 fixed on both sides inside the housing assembly 1. The lower ends of the two tension springs 12 are respectively fixedly connected to two foot pedals 26. The two foot pedals 26 are slidably mounted on opposite side walls inside the housing assembly 1. When the operator steps on the foot pedals 26, the foot pedals 26 will descend, thereby driving the corresponding components to operate. At the same time, the tension springs 12 will be stretched, allowing the support plate 11 to move. When the external force disappears, the tension springs 12 can pull the foot pedals 26 upward, and the corresponding components will reset, thus fixing the support plate 11. Both sides of the housing assembly 1 are fixed with support frames 28. An inclined plate 27 is rotatably sleeved within the support frame 28. The two ends of the synchronous shaft 38 pass through the two support frames 28 respectively and are fixedly connected to the two inclined plates 27. In actual production, a block is rotatably connected to the upper end of the inclined plate 27. This block is slidably installed within the foot pedal assembly 26. The vertical setting of the foot pedal assembly 26 allows the positions of the block on the inclined plate 27 and the foot pedal assembly 26 to change, enabling the inclined plate 27 to move in a direction parallel to the foot pedal assembly 26. When the inclined plate 27 rotates, the synchronous shaft 38 rotates synchronously with it. Simultaneously, the synchronous shaft 38 and the inclined plate 27 are coaxially arranged so that the rotation of the inclined plate 27 causes the synchronous shaft 38 to rotate as well. The upper ends of the two inclined plate components 27 are slidably mounted on the lower ends of the two foot pedal components 26, respectively; lifting rods 23 are slidably mounted on the bottom of the two housing assemblies 1, and linkage rods 24 are fixed on the lifting rods 23. The inclined plate component 27 has a moving opening 35, and a support block 36 is slidably mounted in the moving opening 35. One end of the two linkage rods 24 is rotatably sleeved on the two support blocks 36. When the inclined plate component 27 deflects, the support block 36 in the inclined plate component 27 will move in the moving opening 35. The deflection of the support block 36 can drive the linkage rods 24 to rise and fall. When the linkage rods 24 rise and fall, they can rise and fall through the lifting rods 23 and the lifting rack 22. When the lifting rack 22 descends, it is no longer engaged with the fixed rack 21. At this time, the bearing plate component 11 can move. Two fixed racks 21 are fixed on both sides of the lower end of the bearing plate 11, and two lifting racks 22 are fixed on the upper end of the two lifting rods 23. The two lifting racks 22 mesh with the two fixed racks 21 respectively. When the lifting racks 22 descend and no longer mesh with the fixed racks 21, the bearing plate 11 and the fixed racks 21 at its lower end can move.

[0039] In this embodiment, the synchronous shaft 38 and the inclined plate 27 are coaxially arranged. The coaxial arrangement enables the inclined plate 27 and the synchronous shaft 38 to rotate synchronously. That is, when the foot pedal 26 is stepped on, the inclined plate 27 and the synchronous shaft 38 can rotate synchronously. The synchronous shaft 38 can drive the eccentric wheel 20 to rotate. The eccentrically arranged eccentric wheel 20 can push the pusher 19 to rise and fall.

[0040] In this embodiment, the diameter of the second linkage gear 30 is larger than the diameter of the first linkage gear 31. The change in diameter allows the first linkage gear 31 to rotate when the abutting rack 29 and the rear end of the housing assembly 1 are in contact. The first linkage gear 31 can then drive the second linkage gear 30 to rotate, thus expanding the moving distance of the L-shaped gear condition 32. The rotation of the second linkage gear 30 causes the two L-shaped gear conditions 32 to move in opposite directions. The two L-shaped gear conditions 32 can then drive the two cable clamps 8 to move in opposite directions. When the two cable clamps 8 move relative to each other, the cable passing through the two cable clamps 8 can be fully clamped. When the two cable clamps 8 separate, the cable can be pulled out. At the same time, the cable can pass through the rear end of the fusion cabinet assembly 5 and extend into the fusion cabinet assembly 5 so that the fusion cabinet assembly 5 can operate normally. The fusion cabinet assembly 5 is composed of various cabinet components, and the cabinet components can be connected by bolts. The equipment within the integrated cabinet component 5 mainly includes primary high-voltage switchgear load switches / circuit breakers, electronic current / voltage sensors, grounding switches, and cable terminals; secondary side integrated DTU terminals, electric operating mechanisms, backup power supplies, and communication modules; and supporting secondary control cables, terminal blocks, temperature and humidity control devices, and grounding systems. In actual production and manufacturing, the enclosure assembly 1 is divided into a high-voltage primary chamber and a secondary measurement and control chamber. The primary equipment signal acquisition and remote control are achieved by relying on secondary cables. In this application, the high-voltage primary chamber and the secondary measurement and control chamber can be set by multiple cabinets in the fusion cabinet assembly 5. The corresponding components are all installed in multiple cabinets in the fusion cabinet assembly 5. The cable components can extend into the fusion cabinet assembly 5 through the two cable clamps 8 and through the rear end of the fusion cabinet assembly 5. A cable penetration port is provided on the enclosure assembly 1 to facilitate cable connection.

[0041] In this embodiment, adjustable screw fasteners 2 are installed at the four lower corners of the housing assembly 1. The adjustable screw fasteners 2 are rotatable screw components, and the lower end of the screw component is connected to the pad component. By rotating the screw component, the distance between the pad component and the bottom of the housing assembly 1 can be changed, so as to effectively ensure the support force. At the same time, the distance between the housing assembly 1 and the pad can be adjusted to ensure the stability of the housing assembly 1.

[0042] In this invention, the operator can adjust the adjustable screw fastener 2 so that the adjustable screw fastener 2 and the base layer are in contact, ensuring the stability of the box assembly 1, while the moving wheel 7 is in contact with the base layer; When installation or maintenance is required, stepping on the foot pedal 26 will cause the foot pedal 26 to push the inclined plate 27 to move in a direction parallel to the foot pedal 26. The rotation of the inclined plate 27 will drive the synchronous shaft 38 to rotate. The rotation of the synchronous shaft 38 will cause the eccentric wheel 20 to rotate. The rotation of the eccentric wheel 20 will push the pusher 19 to rise. The pusher 19 will increase the angle between the two inclined push rods 15 so that the two racks 16 can be separated. The two racks 16 will no longer mesh with the gear 17 and will no longer fix the bearing plate 11 through the gear 17. The staff can pull the support plate 11 to remove the support plate 11 from the box assembly 1. The support plate 11 can be moved by the moving wheels 7 at the lower end of the moving frame 3. The fusion cabinet assembly 5 and cables can be installed on the box assembly 1. Alternatively, the supporting plate 11 can be moved to move the fusion cabinet assembly 5 out of the cabinet assembly 1, so that the fusion cabinet assembly 5 can be exposed for easy maintenance. When the bearing plate 11 moves, the contact rack 29 separates from the side wall inside the housing assembly 1, and the contact rack 29 no longer applies external force to the first linkage gear 31. That is, the first linkage gear 31 and the second linkage gear 30 can rotate, and the L-shaped gear condition 32 can move, that is, the cable clamp 8 can move. The cable is no longer clamped by the two cable clamps 8, which facilitates the maintenance of the cable.
