[0002] The ring main unit is an electrical device for power system, mainly used for receiving and distributing power. The primary device (such as load switch, bus) and the secondary device (such as protection device, measurement and control module) of the traditional ring main unit are independently arranged, the cabinet volume is large (usually a single interval volume reaches 0.5~1 cubic meters), and when installed in urban distribution network (especially underground cable layer, narrow street), it is easy to be limited by space, and it is difficult to meet the intensive power supply demand of "small capacity, multiple distribution points". The traditional ring main unit lacks digital interface and intelligent monitoring function, fault positioning depends on manual inspection, power outage range judgment and recovery time is long (average fault handling time reaches several hours), protection function is single (such as only overcurrent protection), which cannot realize the advanced functions required by power distribution network automation, such as fault self-healing and load transfer, and cannot meet the requirements of intelligent power grid "observable, measurable and controllable". Therefore, special equipment is needed to solve the above problems.

[0003] The compact structure of the primary and secondary fusion ring main unit in the prior art is prone to line cross winding due to the randomness of manual wiring when in use, which increases the difficulty of maintenance and increases the operation and maintenance cost.

[0011] As a further further scheme of the present application: the vertical moving mechanism comprises a connecting column slidably connected to the inside of the mounting plate, and the sliding seat is fixedly connected to the connecting column, a second driving block is fixedly connected to the bottom of the connecting column, and a second reset spring is arranged between the second driving block and the partition plate.

[0012] As a further embodiment of the present invention: the vertical moving mechanism further includes a limiting rubber slidably connected to the inner side of the mounting plate, a first return spring is installed between the limiting rubber and the inner side of the mounting plate, an L-shaped strip is fixedly connected to one side of the first return spring, a connecting strip is fixedly connected to one end of the L-shaped strip, a second rotating wheel is rotatably connected to the inner side of the connecting strip, a ramp is provided on one side of the second driving block, and the second rotating wheel is attached to one side of the ramp.

[0013] This invention also discloses a compact method for a primary and secondary integrated ring main unit, employing the aforementioned compact structure of a primary and secondary integrated ring main unit, comprising the following steps:

[0014] S1. The clips are made of elastic plastic. When installing wiring inside the ring main unit, the staff can install the wires inside the ring main unit through the clips, so that the wires run in the preset direction, avoiding crossing and tangling, reducing the randomness of manual wiring, improving the neatness and maintainability of the wire layout, and allowing for quick location of the wire path during subsequent maintenance, reducing operation and maintenance costs, thereby improving the overall practicality of the device.

[0015] The blocking plate is made of elastic rubber, which can block and open the mounting groove inside the partition. At the same time, the wire can rotate to a certain extent along the rotating column. When the worker pulls out the blocking plate, the buckle can be rotated to allow the wire to pass through the partition and enter the bottom of another mounting plate, thereby improving the flexibility of the device and freeing the wire from being confined to one area, thus improving the overall practicality of the device.

[0016] S2. The fan is controlled by a PLC controller, which can control the fan to start intermittently. When the inside of the ring main unit is working, the wires will generate heat. At this time, the PLC controller controls the fan to start, thereby ventilating the bottom of the partition and dissipating heat from the wires. This removes the accumulated heat and prevents the high temperature from causing aging or poor contact of the wire insulation and connector terminals, thus improving the overall practicality of the device.

[0017] S3. The drive motor is controlled by a PLC controller, which can control the drive motor to start intermittently. When the fan starts to cool the wires, the PLC controller controls the drive motor to start, thereby driving the sliding block to move laterally, which in turn drives the first drive block to move. When the inclined surface on one side of the first drive block moves to contact the first rotating wheel, the inclined surface drives the first rotating wheel to move towards the first rectangular block, thereby causing the sliding plate to move in the opposite direction of the first drive block. When the first rotating wheel moves to the top of the inclined surface, the sliding plate moves to its maximum distance. During this process, when the retaining teeth at the top of the sliding plate contact the gear, the retaining teeth drive the gear to rotate, thereby driving the cover plate to rotate and opening the through slot at the top of the mounting plate. This process dissipates heat from the inside of the ring main unit. The first drive block continues to move. When the first rotating wheel contacts another inclined plane, it gradually resets under the action of the tension spring and the inclined plane. When the first drive block moves to contact the bottom of the first rotating wheel with the other inclined plane, the first rotating wheel completes its reset. At this point, the drive cover plate resets under the action of the locking teeth on the top of the sliding plate, closing the through slot on the top of the mounting plate. This achieves heat dissipation from the outside of this mounting plate. As the inclined plane continues to move, it dissipates heat from the outside of the next mounting plate, thus achieving complete heat dissipation from the inside of the ring main unit. This "zone-by-zone activation" method can precisely release heat dissipation channels for different heat-generating areas, avoiding the "blind heat dissipation" or "heat dissipation blind spots" of traditional fixed ventilation openings. This provides an efficient thermal management solution for the long-term stable operation of the ring main unit, thereby improving the overall practicality of the device.

[0018] S4. When wiring is done to the inside of the ring main unit, the end of the wire connects to the outside through the slot at the top of the mounting plate. Under the action of the outer wall of the wire, the limiting rubber is squeezed, which pushes the two limiting rubbers to move to both sides, thereby driving the connecting strip to move, and then driving the second rotating wheel to move. Under the action of the ramp and the second rotating wheel, the second drive block is pushed to move upward, which drives the sliding seat to move upward, and thus drives the gear to move upward. When the sliding plate moves, the gear disengages from its meshing state, so as not to drive the cover plate to rotate, thereby effectively preventing the cover plate from rotating excessively, thus improving the overall practicality of the device.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting up mounting plates and other components, the electromagnetic field generated by the wires can be effectively blocked from interfering with the surrounding equipment. At the same time, it can prevent external electromagnetic interference from affecting the normal operation of the equipment inside the ring main unit. Furthermore, through electromagnetic shielding measures, the overall anti-electromagnetic interference capability of the ring main unit is enhanced, enabling the equipment to operate stably in complex electromagnetic environments. This improves the anti-interference capability of the equipment, especially in places with harsh electromagnetic environments, such as industrial plants and near substations, thereby improving the overall practicality of the device.

[0021] 2. By setting up parts such as clips, the wires can be installed inside the ring main unit through the clips, so that the wires run in the preset direction, avoiding crossing and tangling, reducing the randomness of manual wiring, improving the neatness and maintainability of the wire layout, and at the same time, the wire path can be quickly located during subsequent maintenance, reducing operation and maintenance costs, thereby improving the overall practicality of the device.

[0022] 3. By setting up components such as blocking plates, wires can pass through the partition to the bottom of another mounting plate, thereby improving the flexibility of the device and freeing the wires from being confined to one area, thus improving the overall practicality of the device.

[0023] 4. By setting an opening mechanism, the cover plate is rotated, thereby opening the through slot on the top of the mounting plate to dissipate heat from the inside of the ring main unit. At this time, the first drive block continues to move. When the first rotating wheel moves to contact another inclined plane, the first rotating wheel gradually resets under the action of the tension spring and the inclined plane. When the first drive block moves to contact the bottom of the first rotating wheel with another inclined plane, the first rotating wheel completes the reset. At this time, under the action of the locking teeth on the top of the sliding plate, the cover plate is driven to reset, thereby closing the through slot on the top of the mounting plate, thus achieving heat dissipation from the outside of this mounting plate. As the inclined plane continues to move, heat dissipation is achieved from the outside of the next mounting plate, thus achieving complete heat dissipation from the inside of the ring main unit. This "zone-by-zone activation" method can accurately release heat dissipation channels for different heat-generating areas, avoiding the "blind heat dissipation" or "heat dissipation blind spots" of traditional fixed ventilation openings. It provides an efficient thermal management solution for the long-term stable operation of the ring main unit, thereby improving the overall practicality of the device.

[0024] 5. By setting up a vertical moving mechanism, the two limiting rubbers are pushed to move to both sides, thereby driving the connecting strip to move, which in turn drives the second rotating wheel to move. Under the action of the ramp and the second rotating wheel, the second driving block is pushed to move upward, thereby driving the sliding seat to move upward, which in turn drives the gear to move upward. Thus, when the sliding plate moves, the gear disengages from its meshing state, preventing the cover plate from rotating. This effectively prevents the cover plate from rotating excessively, thereby improving the overall practicality of the device. Attached Figure Description

[0035] 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.

[0036] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0037] Please see Figures 1-9 This embodiment provides a compact structure and method for a primary and secondary integrated ring main unit, including:

[0038] The ring main unit 1 has multiple partitions 3 fixedly connected to its inner side. A mounting plate 2 is installed between every two partitions 3. The top of the mounting plate 2 has multiple through slots. The inner side of the ring main unit 1 has multiple sets of fixing plates 35 fixedly connected to its inner side. Each set of fixing plates 35 has multiple plates. The top of each fixing plate 35 is rotatably connected to a rotating column 36. The top of the rotating column 36 is fixedly connected to a buckle 37. An electric wire 38 is installed inside each set of buckles 37. The inner side of the partitions 3 has multiple mounting slots. A blocking plate 39 is installed inside the mounting slots. The top of the mounting plate 2 is equipped with a ventilation mechanism, an opening mechanism, and a vertical moving mechanism.

[0039] Adding electromagnetic shielding coatings or using electromagnetic shielding materials to the outer sides of mounting plate 2 and partition plate 3 can effectively block the electromagnetic field generated by wire 38 from interfering with surrounding equipment, and prevent external electromagnetic interference from affecting the normal operation of equipment in ring main unit 1. This is very important for improving the accuracy and stability of signal transmission between primary and secondary fusion equipment, ensuring that relay protection devices, intelligent terminals and other equipment can work reliably. At the same time, through electromagnetic shielding measures, the overall anti-electromagnetic interference capability of the ring main unit is enhanced, so that the equipment can still operate stably in complex electromagnetic environments, thereby improving the anti-interference capability of the equipment, especially in some places with harsh electromagnetic environments, such as industrial plants and near substations, thereby improving the overall practicality of the device.

[0040] The clip 37 is made of elastic plastic. When installing wiring inside the ring main unit 1, the staff can install the wire 38 inside the ring main unit 1 through the clip 37, so that the wire 38 runs along the preset direction, avoiding crossing and tangling, reducing the randomness of manual wiring, improving the neatness and maintainability of the wire 38 layout, and allowing the wire 38 path to be quickly located during subsequent maintenance, reducing operation and maintenance costs, thereby improving the overall practicality of the device.

[0041] The blocking plate 39 is made of elastic rubber and can block and open the mounting groove inside the partition 3. At the same time, the wire 38 can rotate to a certain extent along the rotating column 36. When the operator pulls out the blocking plate 39, the buckle 37 can be rotated to allow the wire 38 to pass through the partition 3 and enter the bottom of another mounting plate 2, thereby improving the flexibility of the device and allowing the wire 38 to be free from being confined to one area, thus improving the overall practicality of the device.

[0042] Please see Figure 3 The ventilation mechanism includes multiple sets of circular grooves 4 opened inside the ring network cabinet 1. Each set of circular grooves 4 has two grooves, and a fan 5 is installed inside one of the circular grooves 4.

[0043] When the inner side of the ring main unit 1 is working, the wire 38 will generate heat. At this time, the PLC controller controls the fan 5 to start, thereby ventilating the bottom of the partition 3 and dissipating heat from the wire 38. This removes the accumulated heat and prevents the high temperature from causing aging or poor contact of the wire insulation and connector terminals, thus improving the overall practicality of the device.

[0044] Please see Figures 4-7The opening mechanism includes multiple sets of sliding seats 6 located on the top of the mounting plate 2, with two sliding seats in each set. A rotating shaft 7 is rotatably connected between every two sliding seats 6. A cover plate 8 is fixedly connected to the outer wall of the rotating shaft 7. Two circular plates 9 are fixedly connected to the outer sides of the two sliding seats 6 at both ends of the rotating shaft 7. Torsion springs 10 are installed between each of the two circular plates 9 and one of the sliding seats 6. The opening mechanism also includes a rotating rod 11 fixedly connected to one side of a circular plate 9. A gear 12 is fixedly connected to one end of the rotating rod 11. A mounting base 14 is fixedly connected to the top of the mounting plate 2. A sliding plate 13 is slidably connected to the inner side of the mounting base 14. Multiple sets of locking teeth are provided on the top of the sliding plate 13. Each set of locking teeth meshes with a gear 12. A tension spring 15 is installed between the sliding plate 13 and the inner side of the ring main unit 1. A power assembly is provided on one side of the mounting base 14; the power assembly includes a first rectangular block 16 fixedly connected to the top of the sliding plate 13, a second rectangular block 17 fixedly connected to one side of the first rectangular block 16, a first rotating wheel 18 rotatably connected to the inner side of the second rectangular block 17, two rectangular plates 19 fixedly connected to the inner side of the ring main unit 1, a limit rod 20 fixedly connected to the inner side of the two rectangular plates 19, a sliding block 21 slidably connected to the outer wall of the limit rod 20, a first driving block 22 fixedly connected to one end of the sliding block 21, and inclined surfaces 25 provided on both sides of the first driving block 22; the power assembly includes a drive motor 23 installed on one side of the rectangular plate 19, the output end of the drive motor 23 passes through to the inner side of the rectangular plate 19 and is fixedly connected to a one-way threaded screw 24, and the sliding block 21 is threadedly connected to the outer wall of the sliding block 21;

[0045] The drive motor 23 is controlled by a PLC controller, which can control the intermittent start of the drive motor 23. When the fan 5 starts to cool the wire 38, the PLC controller controls the drive motor 23 to start, thereby driving the sliding block 21 to move laterally, which in turn drives the first drive block 22 to move. When the inclined surface 25 on one side of the first drive block 22 moves to contact the first rotating wheel 18, the inclined surface 25 drives the first rotating wheel 18 to move towards the first rectangular block 16, thereby causing the sliding plate 13 to move in the opposite direction of the first drive block 22. When the first rotating wheel 18 moves to the top of the inclined surface 25, the sliding plate 13 moves to its maximum distance. During this process, when the retaining teeth at the top of the sliding plate 13 contact the gear 12, the retaining teeth drive the gear 12 to rotate, thereby driving the first drive block 22 to move towards the first rectangular block 16. The rotating cover 8 opens the through slot at the top of the mounting plate 2, thereby dissipating heat from the inside of the ring main unit 1. Meanwhile, the first drive block 22 continues to move. When the first rotating wheel 18 contacts another inclined plane 25, it gradually resets under the action of the tension spring 15 and the inclined plane 25. When the first drive block 22 contacts the bottom of the first rotating wheel 18 against the bottom of another inclined plane 25, the first rotating wheel 18 completes its reset. Then, under the action of the locking teeth at the top of the sliding plate 13, the drive cover 8 resets, closing the through slot at the top of the mounting plate 2, thus dissipating heat from the outside of this mounting plate 2. As the inclined plane 25 continues to move, it dissipates heat from the outside of the next mounting plate 2, achieving complete heat dissipation from the inside of the ring main unit 1. This "zone-by-zone activation" method precisely releases heat dissipation channels for different heat-generating areas, avoiding the "blind heat dissipation" or "heat dissipation blind spots" of traditional fixed ventilation openings. This provides an efficient thermal management solution for the long-term stable operation of the ring main unit, thereby improving the overall practicality of the device.

[0046] Please see Figures 7-9 The vertical moving mechanism includes a connecting column 31 slidably connected to the inner side of the mounting plate 2, and a sliding seat 6 fixedly connected to the connecting column 31. A second driving block 32 is fixedly connected to the bottom of the connecting column 31, and a second return spring 33 is installed between the second driving block 32 and the partition plate 3. The vertical moving mechanism also includes a limiting rubber 26 slidably connected to the inner side of the mounting plate 2. A first return spring 27 is installed between the limiting rubber 26 and the inner side of the mounting plate 2. An L-shaped strip 28 is fixedly connected to one side of the first return spring 27. A connecting strip 29 is fixedly connected to one end of the L-shaped strip 28. A second rotating wheel 30 is rotatably connected to the inner side of the connecting strip 29. A ramp 34 is provided on one side of the second driving block 32, and the second rotating wheel 30 is attached to one side of the ramp 34.

[0047] When the wire 38 is connected to the inside of the ring main unit 1, the end of the wire 38 is connected to the outside through the slot at the top of the mounting plate 2. Under the action of the outer wall of the wire 38, the limiting rubber 26 is squeezed, thereby pushing the two limiting rubbers 26 to move to both sides, thereby driving the connecting strip 29 to move, and then driving the second rotating wheel 30 to move. Under the action of the ramp 34 and the second rotating wheel 30, the second driving block 32 is pushed to move upward, thereby driving the sliding seat 6 to move upward, and thus driving the gear 12 to move upward. When the sliding plate 13 moves, the gear 12 disengages from its meshing state, so as not to drive the cover plate 8 to rotate, thereby effectively preventing the cover plate 8 from rotating excessively, thus improving the overall practicality of the device.

[0048] The following describes a compact method for designing a primary and secondary integrated ring main unit, based on the aforementioned compact structure. The method includes the following steps:

[0049] S1. The clip 37 is made of elastic plastic. When installing wiring on the inside of the ring main unit 1, the staff can install the wire 38 on the inside of the ring main unit 1 through the clip 37, so that the wire 38 runs along the preset direction, avoiding crossing and tangling, reducing the randomness of manual wiring, improving the neatness and maintainability of the wire 38 layout, and at the same time, the path of the wire 38 can be quickly located during subsequent maintenance, reducing operation and maintenance costs, thereby improving the overall practicality of the device.

[0050] The blocking plate 39 is made of elastic rubber and can block and open the mounting groove inside the partition 3. At the same time, the wire 38 can rotate to a certain extent along the rotating column 36. When the operator pulls out the blocking plate 39, the buckle 37 can be rotated to allow the wire 38 to pass through the partition 3 and enter the bottom of another mounting plate 2, thereby improving the flexibility of the device and allowing the wire 38 to be free from being confined to one area, thus improving the overall practicality of the device.

[0051] S2. Fan 5 is controlled by a PLC controller, which can control the intermittent start of fan 5. When the inside of the ring main unit 1 is working, the wire 38 will dissipate heat. At this time, the PLC controller controls the fan 5 to start, thereby ventilating the bottom of the partition 3 and dissipating heat from the wire 38. This removes the accumulated heat and prevents the high temperature from causing aging or poor contact of the wire insulation layer and connector terminals, thereby improving the overall practicality of the device.

[0052] S3. The drive motor 23 is controlled by a PLC controller, which can control the intermittent start of the drive motor 23. When the fan 5 starts to cool the wire 38, the PLC controller controls the drive motor 23 to start, thereby driving the sliding block 21 to move laterally, thus driving the first drive block 22 to move. When the inclined surface 25 on one side of the first drive block 22 moves to contact the first rotating wheel 18, the inclined surface 25 drives the first rotating wheel 18 to move towards the first rectangular block 16, thereby causing the sliding plate 13 to move in the opposite direction of the first drive block 22. When the first rotating wheel 18 moves to the top of the inclined surface 25, the sliding plate 13 moves to its maximum distance. During this process, when the locking teeth at the top of the sliding plate 13 contact the gear 12, the locking teeth drive the gear 12 to rotate, thereby... The cover plate 8 is rotated, opening the through slot at the top of the mounting plate 2, thereby dissipating heat from the inside of the ring main unit 1. The first drive block 22 continues to move. When the first rotating wheel 18 contacts another inclined plane 25, it gradually resets under the action of the tension spring 15 and the inclined plane 25. When the first drive block 22 contacts the bottom of the first rotating wheel 18 with the bottom of another inclined plane 25, the first rotating wheel 18 completes its reset. At this point, the cover plate 8 resets under the action of the locking teeth at the top of the sliding plate 13, closing the through slot at the top of the mounting plate 2, thus dissipating heat from the outside of this mounting plate 2. As the inclined plane 25 continues to move, it dissipates heat from the outside of the next mounting plate 2, achieving complete heat dissipation from the inside of the ring main unit 1. This "zone-by-zone activation" method can precisely release heat dissipation channels for different heat-generating areas, avoiding the "blind heat dissipation" or "heat dissipation blind spots" of traditional fixed ventilation openings. This provides an efficient thermal management solution for the long-term stable operation of the ring main unit, thereby improving the overall practicality of the device.

[0053] S4. When the wire 38 is connected to the inside of the ring main unit 1, the end of the wire 38 is connected to the outside through the slot at the top of the mounting plate 2. Under the action of the outer wall of the wire 38, the limiting rubber 26 is squeezed, thereby pushing the two limiting rubbers 26 to move to both sides, thereby driving the connecting strip 29 to move, and then driving the second rotating wheel 30 to move. Under the action of the ramp 34 and the second rotating wheel 30, the second driving block 32 is pushed to move upward, thereby driving the sliding seat 6 to move upward, and thus driving the gear 12 to move upward. When the sliding plate 13 moves, the gear 12 disengages from its meshing state, so as not to drive the cover plate 8 to rotate, thereby effectively preventing the cover plate 8 from rotating excessively, thus improving the overall practicality of the device.

5. The method of using the compact structure of the primary and secondary integrated ring main unit according to claim 4, characterized in that, Includes the following steps: S1. The buckle (37) is made of elastic plastic. When installing wiring on the inside of the ring main unit (1), the worker installs the wire (38) on the inside of the ring main unit (1) through the buckle (37), so that the wire (38) runs along the preset direction. The blocking plate (39) is made of elastic rubber. It blocks and opens the mounting groove on the inside of the partition (3). At the same time, the wire (38) rotates to a certain extent along the rotating column (36). When the worker pulls out the blocking plate (39), by rotating the buckle (37), the wire (38) passes through the partition (3) and enters the bottom of another mounting plate (2). S2. The fan (5) is controlled by the PLC controller, which controls the fan (5) to start intermittently. When the inside of the ring main unit (1) is working, the wires (38) will dissipate heat. At this time, the PLC controller controls the fan (5) to start, thereby ventilating the bottom of the partition (3) and dissipating heat from the wires (38). S3. The drive motor (23) is controlled by the PLC controller, which controls the drive motor (23) to start intermittently. When the fan (5) starts to cool the wire (38), the PLC controller controls the drive motor (23) to start, thereby driving the sliding block (21) to move laterally, thereby driving the first drive block (22) to move. When the inclined surface (25) on one side of the first drive block (22) moves to contact the first rotating wheel (18), the first rotating wheel (18) is driven to move towards the first rectangular block (16) under the action of the inclined surface (25), thereby causing the sliding plate (13) to move in the opposite direction of the first drive block (22). When the first rotating wheel (18) moves to the top of the inclined surface (25), the sliding plate (13) moves to the maximum distance. During this process, when the locking teeth at the top of the sliding plate (13) contact the gear (12), the gear (12) is driven by the locking teeth. The first drive block (22) rotates, thereby driving the cover plate (8) to rotate, thereby opening the through slot at the top of the mounting plate (2), thus dissipating heat on the inside of the ring main unit (1). At this time, the first drive block (22) continues to move. When the first rotating wheel (18) moves to contact another inclined plane (25), the first rotating wheel (18) gradually resets under the action of the tension spring (15) and the inclined plane (25). When the first drive block (22) moves to contact the bottom of the first rotating wheel (18) with the other inclined plane (25), the first rotating wheel (18) completes the reset. At this time, under the action of the locking teeth at the top of the sliding plate (13), the cover plate (8) is driven to reset, thereby closing the through slot at the top of the mounting plate (2), thus achieving heat dissipation on the outside of this mounting plate (2). When the inclined plane (25) continues to move, it dissipates heat on the outside of the next mounting plate (2), thus achieving complete heat dissipation on the inside of the ring main unit (1). S4. When the wire (38) and the inner side of the ring main unit (1) are connected, the end of the wire (38) is connected to the outside through the slot at the top of the mounting plate (2). Under the action of the outer wall of the wire (38), the limiting rubber (26) is squeezed, thereby pushing the two limiting rubbers (26) to move to both sides, thereby driving the connecting strip (29) to move, and then driving the second rotating wheel (30) to move. Under the action of the ramp (34) and the second rotating wheel (30), the second driving block (32) is pushed to move upward, thereby driving the sliding seat (6) to move upward, thereby driving the gear (12) to move upward. When the sliding plate (13) moves, the gear (12) disengages from its meshing state, thus preventing the cover plate (8) from rotating, thereby effectively preventing the cover plate (8) from rotating excessively.
