Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to an intelligent adaptive switchgear trolley operating device. Background Technology

[0002] A trolley-type switchgear is a high-voltage power control device. Its core feature is that the main electrical components, such as circuit breakers and transformers, are mounted on a movable trolley. Quick separation and connection of the equipment are achieved through pushing, pulling, or sliding along rails. Removable baffles divide the cabinet into circuit breaker compartments, busbar compartments, and cable compartments, achieving functional zoning and insulation isolation. Based on the trolley rail position, it is divided into floor-mounted and center-mounted types, with the center-mounted type improving operational reliability due to the closer contact distance. The trolley-type design allows for the isolation of faulty units without complete power outage, avoiding the drawbacks of traditional fixed switchgear requiring overall power outage for maintenance, reducing the scope and duration of power outages. Simultaneously, the baffles isolate each functional compartment to prevent accidental contact with live parts and have an anti-misoperation interlocking mechanism. The center-mounted structure further reduces the distance between the trolley and the stationary contacts, minimizing the possibility of operational errors.

[0003] Currently, handcart-type switchgear comes in various specifications, each with different interfaces, resulting in a rather messy interface. Furthermore, the joints are usually secured with steel balls to prevent them from falling off, which also hinders maintenance. When pushing the circuit breaker along the rails, a considerable amount of force is required to crank the lever, which is quite strenuous. Moreover, if the circuit breaker gets stuck, the equipment is easily damaged by the force of the crank.

[0004] Therefore, based on the above problems, we invented an intelligent adaptive switchgear trolley operating device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent adaptive switchgear trolley operating device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent adaptive switchgear trolley operating device, comprising a cabinet, multiple cabinet doors installed at the front end of the cabinet, vertical partitions installed inside the cabinet, and an instrument compartment, a trolley compartment, a cable compartment, and a busbar compartment. A circuit breaker and a directional control box are installed inside the trolley compartment. A push screw is rotatably installed between the directional control box and the vertical partitions. The push screw is threaded through the circuit breaker. A drive mechanism for driving the push screw is provided inside the directional control box. Multiple terminals are installed on the circuit breaker, and main connectors are installed on the terminals. A secondary connector matching the main connector is installed inside the busbar compartment. The main connector and the secondary connector are connected by a connecting mechanism. A locking mechanism for locking the circuit breaker is provided on the vertical partitions.

[0007] Furthermore, the driving mechanism includes an outer ring disposed within a reversing box, two sliders mounted outside the outer ring, two switching screws rotatably mounted inside the reversing box, each screw threaded through one of the sliders, a switching motor mounted inside the reversing box, the drive shaft of the switching motor coaxially mounted with one of the switching screws, the two switching screws being connected via a transmission mechanism, a fixed plate rotatably mounted inside the outer ring, multiple secondary gears disposed within the outer ring, the secondary gears being rotatably mounted with the fixed plate via an intermediate shaft, annular toothed grooves meshing with the multiple secondary gears on the inner wall of the outer ring, a power gear disposed within the outer ring, the power gear matching the multiple secondary gears, multiple limiting rods fixedly mounted on the fixed plate, each limiting rod matching the power gear, a sliding rod coaxially mounted on the fixed plate, the sliding rod penetrating the reversing box and slidably mounted with a pushing screw, a main shaft coaxially mounted on the power gear, the end of the main shaft away from the power gear penetrating the outer ring and the reversing box and fixed with a rotating plate.

[0008] Furthermore, the transmission mechanism includes two transmission gears, which are coaxially mounted with two switching screws respectively.

[0009] Furthermore, the rotating plate has a square groove at the end away from the directional box. The main shaft rotates through the rotating plate and is coaxially mounted with a tangential gear. A Y-shaped plate is rotatably mounted on the inner wall of the square groove. The Y-shaped plate matches the tangential gear. A U-shaped sliding plate is slidably fitted on the outside of the Y-shaped plate. A U-shaped fixing plate is rotatably mounted on the outside of the U-shaped sliding plate. The U-shaped fixing plate is slidably mounted on the inner wall of the square groove. A tangential screw is rotatably mounted in the square groove. The tangential screw rotates through the U-shaped fixing plate. A tangential motor is installed in the square groove. The drive shaft of the tangential motor is coaxially mounted with the tangential screw. A square plate is fixedly installed in the square groove. Multiple limiting blocks are fixed at the end of the square plate away from the bottom of the square groove. A rocker mechanism matching the rotating plate is provided on the outside of the cabinet.

[0010] Furthermore, the rocker mechanism includes a rocker arm with a handle mounted on it. A grip is rotatably mounted on the handle. A cover ring is fixed at the end of the rocker arm away from the handle. The cover ring corresponds to the rotating plate. A square block is installed inside the cover ring. The square block has a limiting insertion hole that matches the limiting insertion block.

[0011] Furthermore, the connection mechanism includes a buffer box installed on the rear side of the auxiliary connector. Two buffer plates are slidably installed inside the buffer box and connected by a scissor fork. Multiple buffer springs are installed between the two buffer plates. The auxiliary connector has two connectors connected to the main connectors. A limiting sleeve is slidably fitted over the main connector and is fixedly connected to the buffer box. The main connector passes through the buffer box and the two buffer plates. The connection mechanism also includes a connector block fixed to the inner wall of the main connector. The connector block has two matching grooves at one end facing the auxiliary connector. The two matching grooves correspond to the two connectors respectively. Matching blocks are slidably installed in the matching grooves and match the connectors. An auxiliary connector is fixed to one end of the matching block and passes through the connector block. A sliding plate is fixedly fitted over the auxiliary connector and is slidably connected to the inner wall of the main connector. A return spring is fitted over the auxiliary connector and its two ends are fixedly connected to the sliding plate and the connector block respectively.

[0012] Furthermore, the portion of the main cable located between the buffer plates is folded, and the main cable is fixedly connected to the buffer plate at the position furthest from the connector on the buffer plate.

[0013] Furthermore, both the matching block and the connector are equipped with matching strong magnets.

[0014] Furthermore, the snap-fit ​​mechanism includes two snap-fit ​​frames fixedly mounted on the vertical partition plate. A wedge-shaped block matching the snap-fit ​​frame is mounted on the terminal block. Two mounting plates are fixedly mounted on the vertical partition plate. A bidirectional lead screw is rotatably connected between the two mounting plates. A drive motor is mounted on the mounting plate. The drive shaft of the drive motor rotates through the mounting plate and is coaxially mounted with the bidirectional lead screw.

The bidirectional lead screw is threaded through the two U-shaped push plates.

[0015] Furthermore, ring-type pressure sensors are installed on the inner sides of both ends of the grip, and a ring-type vibrator is installed at the middle position of the inner side of the grip. The ring-type sensors are electrically connected to the ring-type vibrator.

[0016] Compared with the prior art, the present invention provides an intelligent adaptive switchgear trolley operating device, which has the following beneficial effects: 1. By setting up a drive mechanism: the torque of the rocker arm can be adjusted as needed, and the appropriate torque can be adjusted according to different switch cabinets. When pushing the circuit breaker, it is more labor-saving and convenient.

[0017] 2. By setting up a rotating plate and rocker mechanism: When the circuit breaker is pushed, no force is applied when the rocker is rotated in the opposite direction, which reduces the impact of erroneous operation. At the same time, when excessive force is applied, the connection between the rotating plate and the main shaft can be automatically separated to avoid damage to the switch cabinet due to excessive force.

[0018] 3. The connection mechanism is designed to be magnetic, ensuring a stable connection without jamming, and facilitating subsequent separation and maintenance.

[0019] This application allows for adjustment of the rotational torque, which is more labor-saving, reduces the impact of operational errors, avoids damage to the switchgear, and facilitates subsequent maintenance. Attached Figure Description

[0022] 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.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an intelligent adaptive switchgear trolley operating device.

[0024] Example 1 like Figures 1-13As shown, the intelligent adaptive switchgear trolley operating device includes a cabinet 1, with multiple cabinet doors 2 installed at the front end of the cabinet 1. A vertical partition 3 is installed inside the cabinet 1. The cabinet 1 contains an instrument compartment 4, a trolley compartment 5, a cable compartment 6, and a busbar compartment 7. A circuit breaker 8 and a steering box 9 are installed in the trolley compartment 5. A push screw 35 is rotatably installed between the steering box 9 and the vertical partition 3. The push screw 35 is threaded through the circuit breaker 8. A drive mechanism 27 for driving the push screw 35 is provided in the steering box 9. Multiple terminals 10 are installed on the circuit breaker 8. A main connector 11 is installed on the terminal 10. A secondary connector 12 that matches the main connector 11 is installed in the busbar compartment 7. The main connector 11 and the secondary connector 12 are connected by a connecting mechanism 14. A snap-fit ​​mechanism 61 for snapping the circuit breaker 8 is provided on the vertical partition 3.

[0025] To ensure a stable connection between the main connector 11 and the auxiliary connector 12, a snap-fit ​​mechanism 61 is provided. The snap-fit ​​mechanism 61 includes two snap-fit ​​frames 62 fixedly mounted on the vertical partition plate 3. A wedge-shaped block 63 matching the snap-fit ​​frame 62 is installed on the terminal post 10. Two mounting plates 65 are fixedly mounted on the vertical partition plate 3. A bidirectional lead screw 66 is rotatably connected between the two mounting plates 65. A drive motor 17 is mounted on the mounting plate 65. The drive shaft of the drive motor 17 rotates through the mounting plate 65 and is coaxially mounted with the bidirectional lead screw 66. A U-shaped push plate 64 is slidably provided through the mounting plate 65. The U-shaped push plate 64 matches the wedge-shaped block 63. The bidirectional lead screw 66 is threaded through the two U-shaped push plates 64.

[0026] Through the above technical features: when the main connector 11 and the auxiliary connector 12 are connected, the circuit breaker 8 is close to the vertical partition 3. At this time, the wedge block 63 is inserted into the snap-fit ​​frame 62, which can ensure a stable connection between the main connector 11 and the auxiliary connector 12; when the main connector 11 and the auxiliary connector 12 need to be separated, the drive shaft of the motor 17 drives the bidirectional lead screw 66 to rotate. The bidirectional lead screw 66 drives the two U-shaped push plates 64 to move relative to each other. The U-shaped push plates 64 push the wedge block 63, so that the wedge block 63 moves out of the snap-fit ​​frame 62. The snap-fit ​​frame 62 does not limit the wedge block 63, which makes it easy to separate the main connector 11 and the auxiliary connector 12 in the future.

[0027] To drive the circuit breaker 8 with different torques, a drive mechanism 27 is provided. The drive mechanism 27 includes an outer ring 28 located within a directional adjustment box 9, with two sliders 29 mounted outside the outer ring 28. Two switching screws 30 are rotatably mounted inside the directional adjustment box 9, each threaded through one of the sliders 29. A switching motor 31 is installed inside the directional adjustment box 9, with its drive shaft coaxially mounted with one of the switching screws 30. The two switching screws 30 are connected by a transmission mechanism 32. Notably, the transmission mechanism 32 includes two transmission gears 33, each coaxially mounted with one of the switching screws 30. A transmission gear ring 34 is rotatably mounted inside the directional adjustment box 9, and the transmission gear ring 34 has a mechanism that corresponds to the two transmission gears 33. The outer ring 28 has a meshing annular toothed groove. A fixed plate 36 is rotatably mounted inside the outer ring 28. Multiple secondary gears 39 are provided inside the outer ring 28. The secondary gears 39 are rotatably mounted to the fixed plate 36 via an intermediate shaft 38. The inner wall of the outer ring 28 has annular toothed grooves that mesh with the multiple secondary gears 39. A power gear 41 is provided inside the outer ring 28. The power gear 41 matches the multiple secondary gears 39. Multiple limiting rods 37 are fixedly mounted on the fixed plate 36. The multiple limiting rods 37 match the power gear 41. A sliding rod 42 is coaxially mounted on the fixed plate 36. The sliding rod 42 passes through the adjusting box 9 and is slidably mounted with the push screw 35. A main shaft 40 is coaxially mounted on the power gear 41. The end of the main shaft 40 away from the power gear 41 passes through the outer ring 28 and the adjusting box 9 and is fixed with a rotating plate 43.

[0028] Through the above technical features: the drive shaft of the switching motor 31 drives the switching screw 30 to rotate, the switching screw 30 drives the slider 29 to move, the slider 29 drives the outer ring 28 to move, the outer ring 28 drives the fixed plate 36 to move, and the fixed plate 36 drives the secondary gear 39 and the limit rod 37 to move. When a larger torque is required to push the circuit breaker 8, the power gear 41 meshes with the secondary gear 39. At this time, when the rotating plate 43 rotates, the rotating plate 43 drives the main shaft 40 to rotate, the main shaft 40 drives the power gear 41 to rotate, and the power gear 41 drives the secondary gear 39 to rotate. Since the current position of the outer ring 28 is fixed, under the action of the annular tooth groove, the secondary gear 39 revolves around the sliding rod 42 as the center. The secondary gear 39 passes through the middle... The shaft 38 drives the fixed plate 36 to rotate, the fixed plate 36 drives the sliding rod 42 to rotate, the sliding rod 42 drives the push screw 35 to rotate, and the push screw 35 drives the circuit breaker 8 to move. At this time, the speed ratio between the main shaft 40 and the push screw 35 is greater than that of the cabinet 1, so a larger torque can be used to push the circuit breaker 8. When a smaller torque is needed to push the circuit breaker 8, the power gear 41 is engaged with the limit plug 37. At this time, when the power gear 41 rotates, it will directly drive the fixed plate 36 to rotate through the limit plug 37. At this time, the speed ratio between the main shaft 40 and the push screw 35 is equal to that of the cabinet 1, so a smaller torque can be used to push the circuit breaker 8. When pushing the circuit breaker 8, the rotation torque can be adjusted according to the current switch cabinet conditions, which is more labor-saving when using it.

[0029] In this invention, the connecting mechanism 14 includes a buffer box 15 installed behind the auxiliary connector 12. Two buffer plates 16 are slidably installed inside the buffer box 15 and connected by a scissor fork 21. Multiple buffer springs 22 are installed between the two buffer plates 16. The auxiliary connector 12 has two connectors 19, and a main cable 18 is connected to each connector 19. A limiting sleeve 20 is slidably fitted around the main cable 18 and is fixedly connected to the buffer box 15. The main cable 18 passes through the buffer box 15 and the two buffer plates 16. Notably, the portion of the main cable 18 between the buffer plates 16 is folded, and the main cable 18 is fixedly connected to the buffer plate 16 at the position furthest from the connectors 19. The connecting mechanism 14 also includes a wiring block 24 fixed to the inner wall of the main connector 11. The wiring block 24 has two matching slots 26 at one end facing the auxiliary connector 12. The two matching slots 26 correspond to the two connectors 19 respectively. Matching blocks 25 are slidably installed in the matching slots 26. It should be noted that the matching blocks 25 and the connectors 19 are equipped with matching strong magnets. The matching blocks 25 match the connectors 19. A secondary connector cable 59 is fixed at one end of the matching block 25. The secondary connector cable 59 passes through the wiring block 24. A sliding plate 23 is fixedly sleeved on the outer side of the secondary connector cable 59. The sliding plate 23 is slidably connected to the inner wall of the main connector 11. A return spring 60 is sleeved on the outer side of the secondary connector cable 59. The two ends of the return spring 60 are fixedly connected to the sliding plate 23 and the wiring block 24 respectively.

[0030] Through the above technical features: when the main connector 11 and the auxiliary connector 12 are connected, the connector 19 and the matching block 25 are attracted by a strong magnet, and the connector 19 is steadily inserted into the matching block 25, thus completing the connection. During the connection process, the connector 19 pulls the main cable 18 to move under the action of attraction, and the main cable 18 compresses the buffer spring 22, so that the two buffer plates 16 are brought closer to each other until the distance moved by the main cable 18 is sufficient for the connector 19 to be engaged with the matching block 25. Similarly, the auxiliary cable 59 will also move a certain distance, so that the return spring 60 is in a compressed state. When the main connector 11 and the auxiliary connector 12 are not connected, the connector 19 can stably contact and abut against the limiting sleeve 20 under the elastic force of the buffer spring 22, and the matching block 25 is also located deep inside the matching groove 26.

[0031] In this invention, a square groove 44 is provided at the end of the rotating plate 43 away from the adjusting box 9. The main shaft 40 rotates through the rotating plate 43 and is coaxially mounted with a tangential gear 47. A Y-shaped plate 48 is rotatably mounted on the inner wall of the square groove 44. The Y-shaped plate 48 matches the tangential gear 47. A U-shaped slide plate 49 is slidably sleeved on the outside of the Y-shaped plate 48. A U-shaped fixing plate 50 is rotatably mounted on the outside of the U-shaped slide plate 49. The U-shaped fixing plate 50 is slidably mounted on the inner wall of the square groove 44. A tangential screw 51 is rotatably mounted inside the square groove 44. The tangential screw 51 rotates through the U-shaped fixing plate 50. A tangential screw 51 is installed inside the square groove 44. A tangential motor 52 has its drive shaft coaxially mounted with a tangential screw 51. A square plate 45 is fixedly installed inside a square groove 44. Multiple limiting blocks 46 are fixed to one end of the square plate 45 away from the bottom of the square groove 44. A rocker mechanism 13 matching the rotating plate 43 is provided outside the cabinet 1. It should be noted that pressure sensors are installed on both arms of the Y-shaped plate 48, and these pressure sensors are electrically connected to the tangential motor 52. The Y-shaped plate 48 consists of two arms and a main body, which are rotatably mounted to the main body. The rotation angle is 0°-10° (rotation range as shown in the image). Figure 13 (As shown by the dashed line).

[0032] It should be noted that the rocker mechanism 13 includes a rocker arm 53, a handle 57 is mounted on the rocker arm 53, a grip sleeve 58 is rotatably mounted on the handle 57, a cover ring 54 is fixed at the end of the rocker arm 53 away from the handle 57, the cover ring 54 corresponds to the rotating plate 43, a square block 55 is installed inside the cover ring 54, and the square block 55 is provided with a limit insertion hole 56 that matches the limit insertion block 46.

[0033] Through the above technical features: when the circuit breaker 8 needs to be pushed forward, the tangential motor 52 drives the tangential screw 51 to rotate, the tangential screw 51 drives the U-shaped fixed plate 50 to move, and the U-shaped fixed plate 50 drives the Y-shaped plate 48 to rotate through the U-shaped sliding plate 49, so that the left arm of the Y-shaped plate 48 abuts against the teeth of the tangential gear 47 (e.g., Figure 12 As shown in the left-right associated state), when the rocker mechanism 13 rotates clockwise to drive the limit block 46 to rotate, the left arm of the Y-shaped plate 48 pushes the tangential gear 47 to rotate. The tangential gear 47 drives the main shaft 40 to rotate, thereby driving the circuit breaker 8 to move forward through the push screw 35. It should be noted that if the rocker mechanism 13 is rotated counterclockwise at this time, the left arm of the Y-shaped plate 48 will slip along the teeth of the tangential gear 47 and cannot smoothly drive the tangential gear 47 to rotate, that is, it will not push the circuit breaker 8 to move in the reverse direction. When it is necessary to push the circuit breaker 8 in the reverse direction, the right arm of the Y-shaped plate 48 is made to abut against the teeth of the tangential gear 47 (e.g., Figure 12As shown in the right-middle associated state), when the rocker mechanism 13 drives the limit block 46 to rotate counterclockwise, the right arm of the Y-shaped plate 48 pushes the tangential gear 47 to rotate, which in turn drives the main shaft 40 to rotate. This, in turn, drives the screw 35 to push the circuit breaker 8 in the opposite direction. It should be noted that if the rocker mechanism 13 is rotated clockwise at this time, the right arm of the Y-shaped plate 48 will slip along the teeth of the tangential gear 47 and will not be able to drive the tangential gear 47 to rotate smoothly. That is, the circuit breaker 8 will not be pushed to move forward, and there will be no situation where the circuit breaker 8 moves in the opposite direction due to operational errors, thus reducing the impact of operational errors. When the circuit breaker 8 moves to the designated position, or when the circuit breaker 8 is stuck, if the force applied by the rocker mechanism 13 is too large, the sensors on both arms of the Y-shaped plate 48 will detect that the pressure is too high. Then, the tangential motor 52 will rotate the Y-shaped plate 48 to the middle position (e.g., Figure 12 (As shown in the state of no association), at this time, both arms of the Y-shaped plate 48 are separated from the tangential gear 47. At this time, the rotating plate 43 cannot drive the main shaft 40 to rotate, thus avoiding damage to the switch cabinet caused by brute force twisting.

[0034] Example 2 The difference between this embodiment and Embodiment 1 is that: ring-type pressure sensors are installed on the inner sides of both ends of the grip sleeve 58, and a ring-type vibrator is installed at the middle position of the inner side of the grip sleeve 58, with the ring-type sensors and the ring-type vibrator being electrically connected.

[0035] The advantage of this embodiment over the first embodiment is that when the rocker arm mechanism 13 is turned with great force, if the resistance is too great, it will cause the operator to exert abnormal force. At this time, the grip 58 will tilt forward or backward under the force of the operator, making the pressure of the grip 58 on the crank handle 57 uneven. When the uneven pressure is too great, if the pressure difference detected by the ring pressure sensor at both ends of the grip 58 exceeds the set pressure difference value, the ring vibrator will generate vibration to warn the operator.

[0036] Working principle: 1) Connection of main connector 11 and auxiliary connector 12: When the main connector 11 and auxiliary connector 12 are connected, the circuit breaker 8 is close to the vertical partition plate 3. At this time, the wedge block 63 is inserted into the snap-fit ​​frame 62, which can ensure a stable connection between the main connector 11 and auxiliary connector 12. When the main connector 11 and auxiliary connector 12 need to be separated, the drive shaft of the motor 17 drives the bidirectional lead screw 66 to rotate. The bidirectional lead screw 66 drives the two U-shaped push plates 64 to move relative to each other. The U-shaped push plates 64 push the wedge block 63, so that the wedge block 63 moves out of the snap-fit ​​frame 62. The snap-fit ​​frame 62 does not limit the wedge block 63, which facilitates the subsequent separation of the main connector 11 and auxiliary connector 12. When the main connector 11 and auxiliary connector 12 are connected, the terminal 19 and the matching block 2 5. Under the attraction of a strong magnet, the connector 19 is firmly inserted into the matching block 25, thus completing the connection. During the connection process, the connector 19 pulls the main cable 18 to move under the attraction, and the main cable 18 compresses the buffer spring 22, causing the two buffer plates 16 to move closer to each other until the distance moved by the main cable 18 is sufficient for the connector 19 to engage with the matching block 25. Similarly, the auxiliary cable 59 will also move a certain distance, causing the return spring 60 to be in a compressed state. When the main connector 11 and the auxiliary connector 12 are not connected, the connector 19 can stably contact and abut against the limiting sleeve 20 under the elastic force of the buffer spring 22, and the matching block 25 is also located deep inside the matching groove 26.

[0037] 2) Torque Adjustment: The drive shaft of the switching motor 31 drives the switching screw 30 to rotate, which in turn moves the slider 29. The slider 29 moves the outer ring 28, which in turn moves the fixed plate 36. The fixed plate 36 then moves the secondary gear 39 and the limit rod 37. When a larger torque is required to push the circuit breaker 8, the power gear 41 meshes with the secondary gear 39. At this time, when the rotating plate 43 rotates, it drives the main shaft 40 to rotate, which in turn drives the power gear 41 to rotate. The power gear 41 then drives the secondary gear 39 to rotate. Since the outer ring 28 is currently fixed, under the action of the annular tooth groove, the secondary gear 39 revolves around the sliding rod 42. The secondary gear 39 rotates through the middle... The shaft 38 drives the fixed plate 36 to rotate, the fixed plate 36 drives the sliding rod 42 to rotate, the sliding rod 42 drives the push screw 35 to rotate, and the push screw 35 drives the circuit breaker 8 to move. At this time, the speed ratio between the main shaft 40 and the push screw 35 is greater than that of the cabinet 1, so a larger torque can be used to push the circuit breaker 8. When a smaller torque is needed to push the circuit breaker 8, the power gear 41 is engaged with the limit plug 37. At this time, when the power gear 41 rotates, it will directly drive the fixed plate 36 to rotate through the limit plug 37. At this time, the speed ratio between the main shaft 40 and the push screw 35 is equal to that of the cabinet 1, so a smaller torque can be used to push the circuit breaker 8. When pushing the circuit breaker 8, the rotation torque can be adjusted according to the current switch cabinet conditions, which is more labor-saving when using it.

[0038] 3) Pushing the circuit breaker 8: When it is necessary to push the circuit breaker 8 in the forward direction, the tangential motor 52 drives the tangential screw 51 to rotate. The tangential screw 51 drives the U-shaped fixing plate 50 to move. The U-shaped fixing plate 50 drives the Y-shaped plate 48 to rotate through the U-shaped sliding plate 49, so that the left arm of the Y-shaped plate 48 abuts against the teeth of the tangential gear 47. Then, the rocker mechanism 13 drives the limit block 46 to rotate clockwise. At this time, the left arm of the Y-shaped plate 48 pushes the tangential gear 47 to rotate. 7 drives the main shaft 40 to rotate, thereby driving the circuit breaker 8 to move forward by pushing the screw 35. It should be noted that if the rocker mechanism 13 is rotated counterclockwise at this time, the left arm of the Y-shaped plate 48 will slip along the teeth of the tangential gear 47 and will not be able to drive the tangential gear 47 to rotate smoothly, that is, it will not drive the circuit breaker 8 to move in the reverse direction. When it is necessary to drive the circuit breaker 8 in the reverse direction, the right arm of the Y-shaped plate 48 is made to abut against the teeth of the tangential gear 47, and then the rocker mechanism 13 drives the limiter to move counterclockwise. When the insertion block 46 rotates, the right arm of the Y-shaped plate 48 pushes the tangential gear 47 to rotate. The tangential gear 47 drives the main shaft 40 to rotate, thereby driving the circuit breaker 8 to move in the opposite direction by pushing the screw 35. It should be noted that if the rocker arm mechanism 13 is rotated clockwise at this time, the right arm of the Y-shaped plate 48 will slip along the teeth of the tangential gear 47 and will not be able to drive the tangential gear 47 to rotate smoothly. That is, the circuit breaker 8 will not be pushed to move forward, and there will be no situation where the circuit breaker 8 moves in the opposite direction due to operation error, thus reducing the impact of operation error. When the circuit breaker 8 moves to the designated position, or when the circuit breaker 8 is stuck, if the force applied by the rocker arm mechanism 13 is too large, the sensors on both arms of the Y-shaped plate 48 will detect that the pressure is too large. Then, the tangential motor 52 will rotate the Y-shaped plate 48 to the middle position. At this time, both arms of the Y-shaped plate 48 are separated from the tangential gear 47. At this time, the rotating plate 43 cannot drive the main shaft 40 to rotate, thus avoiding damage to the switch cabinet due to brute force.
