Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a high and low voltage switchgear. Background Technology

[0002] In modern power systems, high- and low-voltage switchgear is a key device for ensuring the safe distribution and control of power. However, the switchgear equipment currently on the market still has significant shortcomings in several technical aspects, making it difficult to meet the ever-increasing industrial and civil power demands.

[0003] First, existing switchgear has serious compatibility issues in cable connection management. In practical applications, switchgear needs to connect various cables of different specifications and models, with significant differences in diameter and quantity. However, the fixed clamping structure used in existing technologies lacks flexibility and cannot effectively adapt to such diverse needs. This limitation not only increases installation difficulty but may also lead to unstable cable connections, affecting the safety and reliability of the entire power distribution system. This compatibility problem is particularly prominent in large industrial facilities due to the complexity of electrical equipment.

[0004] Secondly, although some improved switchgear equipment has introduced adjustable cable clamping mechanisms in an attempt to solve the cable compatibility problem, these improvements still have obvious shortcomings. Although these clamping devices can theoretically adapt to cables of different specifications, their structural design is too simple and their stability is difficult to guarantee. During the operation of the switchgear, the frequent opening and closing of internal electrical components will generate continuous mechanical vibration. At the same time, external environmental factors such as mechanical impact will also affect the equipment. These factors can easily cause the clamping structure to loosen or shift, making the originally fixed cable connection unstable. This instability not only affects the normal operation of the equipment, but may also cause serious safety accidents.

[0005] In addition, heat dissipation of switchgear is also a technical problem that urgently needs to be solved. During the operation of switchgear, internal components such as circuit breakers, transformers, and busbars continuously generate a large amount of heat. If this heat is not dissipated in a timely and effective manner, the temperature inside the cabinet will continue to rise, affecting the normal operation of the equipment. Existing technologies generally adopt simple ventilation slot designs. This passive heat dissipation method has many limitations. First, the heat dissipation effect is heavily dependent on the ambient temperature and air flow, resulting in poor controllability. Second, the simple ventilation slot structure has low heat dissipation efficiency and cannot meet the heat dissipation requirements of high-power equipment. Third, this design cannot dynamically adjust the heat dissipation capacity for different operating conditions, resulting in unstable heat dissipation. These problems are particularly prominent under high load operation or high ambient temperature conditions, which may lead to equipment overheating protection or even failure. Utility Model Content

The wire clamping device includes a fixed sleeve 2, a connecting plate 3, a connecting spring 4, a movable groove 5, a movable block 6, an adapter groove 7, an adapter 8, an adapter block 9, and a rotating sleeve 10.

The outside of the fixed sleeve 2 is provided with The switch cabinet 1 includes a linkage plate 11, a slide groove 12, a slide rail 13, a linkage hole 14, a linkage rod 15, a linkage spring 16, a fixing block 17, a linkage block 18, and a limit sleeve 19. The linkage plate 11 is rotatably sleeved on the outside of the fixing sleeve 2. The slide groove 12 is opened on the inside of the limit sleeve 19. The slide rail 13 is fixedly installed on the outside of the fixing sleeve 2, and the slide groove 12 is adapted to the slide rail 13. The linkage hole 14 is opened on the linkage plate 11. The linkage rod 15 is fixedly connected to one side of the limit sleeve 19. The two ends of the linkage spring 16 are respectively connected to the linkage block 18 and the fixing block 17. The limit sleeve 19 is sleeved on the outside of the fixing sleeve 2. The linkage block 18 is fixedly connected to one side of the linkage plate 11. The fixing block 17 is fixedly installed on the outside of the fixing sleeve 2. A heat dissipation device is provided inside the switch cabinet 1.

[0032] The heat dissipation device includes a cabinet door 20, ventilation slots 21 and intake fans 22. The cabinet door 20 is movably connected to one side of the switch cabinet 1. Multiple ventilation slots 21 are symmetrically opened on both sides of the switch cabinet 1. Two intake fans 22 are symmetrically installed inside the switch cabinet 1.

[0033] The top of the switch cabinet 1 is equipped with a removable exhaust fan 23.

[0034] Both the exhaust fan 23 and the intake fan 22 have detachable filter plates 24.

[0035] A top cover 25 is fixedly provided on the top of the switch cabinet 1. Side covers 26 and protective covers 27 are symmetrically provided on both sides of the switch cabinet 1. The protective cover 27 is located on the side of the inlet fan 22, and the side cover 26 is located on the side of the ventilation slot 21.

[0036] In this embodiment, when the equipment is operating normally, the internal heat can be discharged through the ventilation slot 21 to achieve natural ventilation and heat dissipation. When the ambient temperature rises and heat gradually accumulates inside the switch cabinet 1, the two intake fans 22 symmetrically arranged inside the switch cabinet 1 are turned on, so that the intake fans 22 draw in outside air and blow away the heat inside the switch cabinet 1, allowing the air to carry the heat out through the ventilation slot 21, achieving automatic heat dissipation. When the heat accumulation inside the equipment is high, the exhaust fan 23 located at the top of the switch cabinet 1 is turned on at the same time as the intake fans 22 are turned on, and the exhaust fan 23 blows the internal heat and air out through the ventilation slot 21. The air is drawn out of the switch cabinet 1 and discharged to the outside, which accelerates the air circulation speed and achieves efficient heat exchange, thereby achieving efficient heat dissipation and ensuring the normal operation of the equipment.

[0037] Please see Figures 3-5 As a further implementation of the overall device: multiple insertion rods 28 are slidably provided on the side wall of the rotating sleeve 10, and a movable spring 29 is provided on the outer side of the rotating sleeve 10. The outer end of the insertion rod 28 is connected to the outer wall of the rotating sleeve 10 through the movable spring 29. Multiple slots 30 are opened on the outer side of the fixed sleeve 2. The inner end of the insertion rod 28 is inserted into the slot 30. A reset spring 31 is movably sleeved on the outer side of the linkage rod 15. One end of the reset spring 31 is connected to the limiting sleeve 19, and the other end of the reset spring 31 is in contact with the linkage plate 11.

[0038] The inner side of the rotating sleeve 10 is fixed with a guide rail 32, and the outer side of the fitting sleeve 8 is provided with a guide groove 33, which is adapted to the guide rail 32.

[0039] A rubber strip 34 is fixedly installed on one side of the movable block 6.

[0040] More specifically, when a cable needs to be connected to the switch cabinet 1, first, the linkage plate 11 is rotated forward, causing the linkage block 18 to rotate. The linkage block 18, together with the fixed block 17, compresses the linkage spring 16. At the same time, the linkage plate 11 causes the linkage hole 14 to rotate. When the linkage spring 16 is compressed to its limit, the linkage hole 14 moves to a position concentric with the linkage rod 15. At this time, the limit sleeve 19 is pushed, causing the linkage rod 15 to slide along the slide rail 13 and the slide groove 12. The linkage rod 15 gradually passes into the linkage hole 14. Simultaneously, the limit sleeve 19, together with the linkage plate 11, compresses the return spring 31 sleeved on the outside of the linkage rod 15. When the return spring 31 is compressed to its limit, the limit sleeve 19 no longer limits the insertion rod 28. Then, the cable is rotated forward. The rotating sleeve 10, through the cooperation of the guide rail 32 and the guide groove 33, drives the inner adapter 8 to rotate. Then, the adapter 8 drives the multiple adapter blocks 9 set on the outer side to slide along the adapter groove 7. Due to the special spiral structure design of the adapter groove 7, the adapter blocks 9 drive the adapter 8 to move. While the adapter 8 moves, the connecting spring 4 connected to one side of the connecting plate 3 will gradually reset and push the movable block 6 to always abut against one side of the adapter 8. At the same time, the movable block 6 will slide along the movable groove 5. Due to the unique inclined structure design of the movable groove 5, when the movable block 6 slides against the movable groove 5, it will spread outward. When the movable block 6 moves to one end of the movable groove 5, it passes the cable through the fixed sleeve 2 and thus into the switch cabinet 1. Afterwards, the rotating sleeve 10 is rotated in the reverse direction, causing the adapter 8 to rotate in the reverse direction through the cooperation of the guide rail 32 and the guide groove 33. Then, the adapter 8 will drive the adapter block 9 to slide in the reverse direction along the adapter groove 7. Then, the adapter block 9 will drive the adapter 8 to slide. Then, one side of the adapter 8 will push the movable block 6 to move. Then, the movable block 6 will slide along the movable groove 5, and the movable block 6 will cooperate with the connecting plate 3 to squeeze the connecting spring 4. At the same time, the movable block 6 will gradually move inward. Then, the rubber strip 34 on one side of the movable block 6 will contact the outer wall of the cable. Then, the movable block 6 will continue to move, so that the movable block 6 will completely clamp the cable through the rubber strip 34. At this time, the rotation of the rotating sleeve 10 will stop, and the movable spring 29 will drive the plug rod 28 to slide back and insert into the corresponding slot 3. In position 0, when the limiting sleeve 19 is released, the return spring 31 pushes the limiting sleeve 19 to drive the linkage rod 15 to slide and reset along the slide rail 13 and the slide groove 12. When the return spring 31 is fully reset, the limiting sleeve 19 drives the linkage rod 15 to fully reset, and one end of the linkage rod 15 moves to one side of the linkage plate 11. At this time, the linkage hole 14 loses the limitation of the linkage rod 15. Then, the linkage spring 16 pushes the linkage block 18 to rotate and reset. Then, the linkage block 18 drives the linkage hole 14 to reset and move to a position that does not correspond to the linkage rod 15 through the linkage plate 11. At this time, the linkage rod 15, together with the linkage plate 11, provides stable support for the limiting sleeve 19, and together with the slide rail 13 and the slide groove 12, limits the limiting sleeve 19, thereby locking the limiting sleeve 19 and preventing it from moving.Then, the inner wall of the limiting sleeve 19 limits the outer end of the insertion rod 28 to prevent it from moving. The insertion rod 28 then cooperates with the slot 30 to completely lock the rotating sleeve 10, preventing it from rotating and thus ensuring stable clamping of the cable.

[0041] In summary, during the use or operation of the overall equipment: When the equipment is running normally, the internal heat can be discharged through the ventilation slot 21 to achieve natural ventilation and heat dissipation. When the ambient temperature rises and heat gradually accumulates inside the switch cabinet 1, the two intake fans 22 symmetrically arranged inside the switch cabinet 1 are turned on, allowing the intake fans 22 to draw in outside air and blow away the heat inside the switch cabinet 1, so that the air carries the heat out through the ventilation slot 21, achieving automatic heat dissipation. When the heat accumulation inside the equipment is high, the exhaust fan 23 located at the top of the switch cabinet 1 is turned on at the same time as the intake fans 22 are turned on, and the exhaust fan 23 dissipates the internal heat and... Air is drawn out from the switch cabinet 1 and discharged to the outside, accelerating air circulation and achieving efficient heat exchange, thereby achieving efficient heat dissipation and ensuring normal operation of the equipment. The filter plate 24 effectively prevents foreign objects from entering the switch cabinet 1 from the inlet fan 22 and the exhaust fan 23. The top cover 25 prevents rainwater from entering the switch cabinet 1 from the exhaust fan 23. The side cover 26 effectively prevents rainwater from entering the switch cabinet 1 from the ventilation slot 21. The protective cover 27 effectively prevents rainwater from entering the switch cabinet 1 from the inlet fan 22, enhancing the safety of the equipment and ensuring its safe operation.

[0042] When a cable needs to be connected to switch cabinet 1, first rotate the linkage plate 11 forward, causing the linkage plate 11 to drive the linkage block 18 to rotate. The linkage block 18 will cooperate with the fixed block 17 to compress the linkage spring 16. At the same time, the linkage plate 11 will drive the linkage hole 14 to rotate. When the linkage spring 16 is compressed to its limit, the linkage hole 14 will move to a position concentric with the linkage rod 15. At this time, push the limit sleeve 19. The limit sleeve 19 will drive the linkage rod 15 to slide along the slide rail 13 and the slide groove 12, and the linkage rod 15 will gradually pass into the linkage hole 14. At the same time, the limit sleeve 19 will cooperate with the linkage plate 11 to compress the return spring 31 sleeved on the outside of the linkage rod 15. When the return spring 31 is compressed to its limit, the limit sleeve 19 will no longer limit the insertion rod 28. Then rotate the rotating sleeve 10 forward. The guide rail 32 and guide groove 33 work together to rotate the inner adapter 8. The adapter 8 then drives multiple adapter blocks 9 on the outer side to slide along the adapter groove 7. Due to the special spiral structure design of the adapter groove 7, the adapter blocks 9 drive the adapter 8 to move. While the adapter 8 moves, the connecting spring 4 connected to one side of the connecting plate 3 gradually resets and pushes the movable block 6 to always abut against one side of the adapter 8. At the same time, the movable block 6 slides along the movable groove 5. Due to the unique inclined structure design of the movable groove 5, as the movable block 6 slides against the movable groove 5, it spreads outward. When the movable block 6 moves to one end of the movable groove 5, it passes the cable through the fixed sleeve 2 and into the switch cabinet 1. After insertion, the rotating sleeve 10 is rotated in the opposite direction. The rotating sleeve 10, through the cooperation of the guide rail 32 and the guide groove 33, causes the adapter 8 to rotate in the opposite direction. Then, the adapter 8 causes the adapter block 9 to slide in the opposite direction along the adapter groove 7. Then, the adapter block 9 causes the adapter 8 to slide. Then, one side of the adapter 8 pushes the movable block 6 to move. Then, the movable block 6 slides along the movable groove 5, and the movable block 6 cooperates with the connecting plate 3 to squeeze the connecting spring 4. At the same time, the movable block 6 gradually moves inward. Then, the rubber strip 34 on one side of the movable block 6 contacts the outer wall of the cable. Then, the movable block 6 continues to move, so that the movable block 6 completely clamps the cable through the rubber strip 34. At this time, the rotating sleeve 10 stops rotating, and the movable spring 29 causes the plug rod 28 to slide back and insert into the corresponding slot 30. At this time, the limit sleeve 19 is released, and the reset spring... 31 will push the limiting sleeve 19 to drive the linkage rod 15 to slide and reset along the slide rail 13 and slide groove 12. When the reset spring 31 is fully reset, the limiting sleeve 19 will drive the linkage rod 15 to be completely reset, and one end of the linkage rod 15 will move to one side of the linkage plate 11. At this time, the linkage hole 14 will lose the limitation of the linkage rod 15. Then the linkage spring 16 will push the linkage block 18 to rotate and reset. Then the linkage block 18 will drive the linkage hole 14 to reset and move to a position that does not correspond to the linkage rod 15 through the linkage plate 11. At this time, the linkage rod 15 and the linkage plate 11 will form a stable support for the limiting sleeve 19, and together with the slide rail 13 and slide groove 12, they will limit the limiting sleeve 19, thereby locking the limiting sleeve 19 and preventing it from moving. Then the inner wall of the limiting sleeve 19 will limit the outer end of the insertion rod 28.To prevent the insertion rod 28 from moving, the insertion rod 28 and the slot 30 cooperate to completely lock the rotating sleeve 10, preventing the rotating sleeve 10 from rotating, thereby ensuring stable clamping of the cable.
