[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figures 1 to 11The remote emergency tripping device provided by this utility model is described below. The remote emergency tripping device includes: a magnetic base, a rotary unlocking mechanism, and a remote pressing mechanism. The magnetic base is magnetically fixed to the switch cabinet. The rotary unlocking mechanism includes a sleeve 1 and an unlocking operation component for driving the sleeve 1 to rotate and unlock the tripping switch. The remote pressing mechanism includes a support plate 24, a protective shell 4, a pneumatic support rod 19 disposed within the protective shell 4, a drive motor 33, and a connecting rod assembly. It also includes a safety switch 7 disposed on the protective shell 4. A clutch is mounted on the main shaft of the drive motor 33. One end of the connecting rod assembly is mounted on the clutch, and the other end is connected to the rear end of the pneumatic support rod 19. The front end of the pneumatic support rod 19 passes through the central hole of the sleeve 1. The safety switch 7 actuates the clutch via a safety fork 23, disengaging the drive motor 33 from the connecting rod assembly. The clutch drives the connecting rod assembly to move, causing the pneumatic support rod 19 to press the tripping switch button.

[0020] The protective shell 4 is fixed on the carrier plate 24, and the rotary unlocking mechanism is rotatably installed in the center hole of the carrier plate 24. The carrier plate 24 is provided with an external threaded sleeve 11, and the magnetic base is provided with an adjusting sleeve 12 that is threadedly engaged with the external threaded sleeve 11 of the carrier plate 24. Rotating the adjusting sleeve 12 can drive the remote pressing mechanism and the rotary unlocking mechanism to slide synchronously along the through hole on the magnetic base, moving back and forth to approach or move away from the switch cabinet.

[0021] A limiting cover 13 of the axial limiting adjustment sleeve 12 is also installed on the magnetic base.

[0022] Compared with the prior art, the remote emergency tripping device provided by this utility model has the following advantages: During operation, the magnetic base is first attached to the switch cabinet, and the sleeve 1 is aligned with the tripping switch; then, by rotating the adjusting sleeve 12, the height of the sleeve 1 from the tripping switch is finely adjusted so that the sleeve 1 reaches the optimal position for rotating and unlocking the tripping switch; then, by rotating the sleeve 1 through the unlocking operation component, the tripping switch is unlocked; after the tripping switch is unlocked, the safety switch 7 is activated to connect the clutch and the connecting rod assembly, and then the drive motor 33 is started remotely with the help of a remote control. The drive motor 33 drives the clutch to rotate, and the clutch drives the connecting rod assembly to rotate, thereby moving the pneumatic support rod 19 forward and pressing the button on the tripping switch, ultimately realizing the remote tripping of the circuit breaker.

[0023] When the switch cabinet button being maintained is abnormally locked, the pneumatic strut is blocked from being pressed, and the pressing force exceeds the set value, the pneumatic strut will retract to avoid secondary damage to the button.

[0024] This application enables emergency tripping of circuit breakers via remote control, eliminating the need for maintenance personnel to manually press the tripping button on-site. This avoids direct personal injury to operators in the event of a sudden switchgear failure, fundamentally reducing safety risks from an operational perspective.

[0025] Of course, remote emergency tripping also requires a control unit. Using a remote control in conjunction with the control unit to start the drive motor 33 is an existing technology widely used in daily life, such as air conditioner remote control, television remote control, and common remote control toy cars. Those skilled in the art can obtain these conventional technologies from the disclosed technologies. However, these conventional circuit controls and wireless controls are not the innovation of this application. The innovation of this application lies in using remote control to achieve the engagement and disengagement of the linkage assembly and the drive motor 33 through the safety switch 7, the safety fork 23, and the clutch. Then, when the tripping button needs to be pressed, the drive motor 33 drives the linkage assembly to rotate, which drives the pneumatic support rod 19 to move linearly, thereby realizing the remote pressing of the circuit breaker's tripping button.

[0026] For example, a power supply, a controller 32, and a wireless module are installed inside the protective housing 4. The protective housing 4 is equipped with a power switch 6, a power indicator light 8, and a power display screen 5 connected in series with the power supply. The power switch 6 is electrically connected to the controller 32, the indicator light, the power display screen 5, and the drive motor 33 to form a power supply circuit. The controller 32 is electrically connected to the wireless module and the drive motor 33. The wireless module is used to receive control signals from an external remote control and transmit them to the controller 32. The controller 32 outputs drive commands to the drive motor 33 according to the control signals to control its start or stop.

[0027] The power supply is a rechargeable battery. A charging port 16 that is electrically connected to the power supply is provided on the protective housing 4. When the battery is depleted and cannot be used, temporary operation can be achieved by connecting an external power source.

[0028] In some embodiments, see Figure 5 , Figures 7 to 11 The clutch includes an inner clutch disc 22 mounted on the main shaft of the drive motor 33 and a shift disc 21 meshing with the outer teeth of the inner clutch disc 22; the shift disc 21 has inner teeth that mesh with the outer teeth of the inner clutch disc 22; the safety shift fork 23 drives the shift disc 21 to move axially along the inner clutch disc 22; the connecting rod assembly is rotatably mounted on the inner clutch disc 22. When the shift disc 21 approaches the connecting rod assembly, the drive motor 33 drives the clutch to rotate, the shift disc 21 shifts the connecting rod assembly to rotate, and drives the pneumatic support rod 19 to approach or move away from the button of the trip switch.

[0029] The beneficial effects of the above technical solution are as follows: (1) Improve operational safety and prevent accidental triggering The inner clutch disc 22 and the actuating disc 21 are always engaged. In the non-operating state, the safety fork 23 drives the actuating disc 21 away from the linkage assembly. Even if the drive motor 33 is accidentally started, it cannot drive the pneumatic strut 19 to move through the linkage assembly, thus cutting off the power transmission path from a mechanical structure. This effectively avoids accidental tripping due to misoperation or motor failure, further enhancing the safety protection performance of the device.

[0030] (2) Achieve precise control of the tripping action. When the safety switch 7 triggers the safety fork 23 to move the actuating disk 21 close to the linkage assembly, the rotational force of the drive motor 33 moves the linkage assembly through the actuating disk 21, causing the pneumatic support rod 19 to complete the action of pressing the trip button. When the actuating disk 21 moves the linkage 180°, since the actuating disk 21 is a one-sided actuating linkage, the linkage is no longer restricted by the return stroke of the actuating disk 21. The linkage and the pneumatic support rod 19 quickly reset under the action of the spring 18 and leave the trip button.

[0031] (4) Linked with safety switch 7 to enhance the standardization of operating procedures. The clutch engagement / disengagement state is entirely controlled by the safety switch 7 via the safety fork 23, forming a fixed process of "safety switch 7 triggering → clutch engaging → power transmission → tripping action". This mandates that the safety switch must be unlocked before operation to prevent unauthorized operations that skip safety steps. The process design further ensures operational safety, making it particularly suitable for scenarios with extremely high requirements for operational standardization, such as high-voltage switchgear.

[0032] In summary, this clutch structure achieves precise and efficient power transmission through mechanical engagement control, while also enhancing safety protection through linkage with the safety switch 7, effectively preventing misoperation. At the same time, it meets the timeliness requirements of emergency tripping, providing key guarantees for the safety and reliability of remote operation.

[0033] In some embodiments, see Figures 7 to 8 The protective housing 4 contains a first guide rail 34, and a first slider that slides on the safety fork 23 is mounted on the first guide rail 34. The first guide rail 34 is parallel to the main shaft of the drive motor 33. The safety switch 7 is mounted on the safety fork 23. The first guide rail 34 ensures that the safety fork 23 moves axially and prevents the safety fork 23 from rotating.

[0034] In some embodiments, see Figures 7 to 9 , Figure 11 The outer circumference of the actuating disk 21 is provided with an annular groove, and one end of the safety fork 23 is inserted into the annular groove. This design allows the safety fork 23 to drive the actuating disk 21 to move axially without being fixedly connected to it, making assembly simple and convenient.

[0035] In some embodiments, see Figure 7 and Figure 8 The linkage assembly includes a rotating arm 20 rotatably mounted on an inner clutch disc 22 and a swing arm 30 rotatably connected to the rotating arm 20; the swing arm 30 is rotatably connected to the rear end of the pneumatic strut 19. When the linkage assembly is linked with the drive motor 33, the actuation disc 21 rotates to drive the rotating arm 20 to rotate, and the swing arm 30 is restricted by the pneumatic strut 19 to swing back and forth, converting the motion into linear movement of the pneumatic strut 19.

[0036] In some embodiments, see Figure 7 and Figure 8 A second slider 28 is installed on the inner side of the protective housing 4. The rear end of the pneumatic strut 19 is connected to a second guide rail 31 that slides with the second slider 28. The swing arm 30 is rotatably connected to the rear end of the second guide rail 31. Through the cooperation of this guide rail and slider, the linear movement of the pneumatic strut 19 is guided and limited, ensuring that the pneumatic strut 19 can effectively press the trip button.

[0037] A limit switch 29 for the limit pneumatic strut 19 is also installed inside the protective housing 4.

[0038] In some embodiments, see Figure 5 A spring 18 is fitted onto the pneumatic strut 19, with both ends of the spring 18 positioned between the second guide rail 31 and the sleeve 1. When the pneumatic strut 19 moves forward, it compresses the spring 18. Simultaneously, the spring 18 provides a buffer reaction force for the pneumatic strut 19, preventing it from directly impacting the trip button and reducing the impact force on the trip button, thus protecting it. After the trip button is pressed, the pneumatic strut 19 can quickly retract from the trip button due to the reset of the spring 18.

[0039] In some embodiments, see Figures 1 to 8 The unlocking operation component includes a wrench bucket 17 and a wrench handle 9 mounted on the wrench bucket 17. The wrench bucket 17 is rotatably fitted into the center hole of the support plate 24. An axial limiting structure is provided between the wrench bucket 17 and the support plate 24 so that when the wrench handle 9 is rotated, the rotation of the wrench bucket 17 drives the socket head 1 to rotate and unlock. When the adjusting sleeve 12 rotates, it moves back and forth with the support plate 24 to achieve fine adjustment of the distance between the socket head 1 and the switch cabinet.

[0040] In the above scheme, the axial limiting structure is an annular step set inside the bearing plate 24 or an annular shoulder set on the wrench barrel 17. This type of axial limiting structure is a commonly used axial limiting structure between shafts and sleeves, and is not marked in the figure. The limiting structure set between the wrench barrel 17 and the bearing plate 24 is intended to allow the wrench barrel 17, the socket head 1, and the one-way bearing between them to move together with the bearing plate 24 when the adjusting sleeve 12 rotates, so as to finely adjust the position of the socket head 1 from the switch cabinet.

[0041] In some embodiments, see Figure 5 and Figure 8 The unlocking operation component also includes a first one-way bearing 25 installed between the wrench barrel 17 and the socket 1, and a second one-way bearing 27 installed between the external threaded sleeve 11 of the bearing plate 24 and the socket 1. The locking direction of the second one-way bearing 27 is opposite to that of the first one-way bearing 25. When the wrench barrel 17 rotates counterclockwise, the socket 1 is driven to rotate counterclockwise through the first one-way bearing 25 to unlock the trip switch. When the wrench barrel 17 rotates clockwise, the socket 1 is locked through the second one-way bearing 27.

[0042] A one-way bearing is a type of bearing that can rotate freely in one direction and is locked in the other. Specifically, the outer ring of the first one-way bearing 25 is keyed to the wrench barrel 17, and its inner ring is keyed to the socket head 1; the outer ring of the second one-way bearing 27 is keyed to the external threaded sleeve 11, and its inner ring is keyed to the socket head 1.

[0043] This application achieves the up-and-down swing of the lever 9 by the cooperation of two one-way bearings. When the lever 9 rotates counterclockwise upwards, it drives the socket 1 to rotate counterclockwise to unlock. When the lever 9 rotates clockwise downwards, the socket 1 is locked by the second one-way bearing 27 and will not rotate.

[0044] A spacer sleeve 26 is provided between the two one-way bearings. The axial limit of the one-way bearing is also limited by an annular shoulder, shaft retaining ring or bore retaining ring, which are commonly used limiting methods in terms of structure.

[0045] In some embodiments, see Figures 1 to 5 The magnetic base includes a fixed housing 2, a fixed magnet 14, and a switching magnetic base 15. The fixed housing 2 has two support arms that can support the switch cabinet, and the fixed magnet 14 and the switching magnetic base 15 are respectively mounted on the two support arms. The fixed magnet 14 can initially magnetically fix the entire device to the switch cabinet, and the switching magnetic base 15 can be used to fine-tune the orientation of the magnetic base. After the orientation of the magnetic base is adjusted, the switching magnetic base 15 is turned on. Furthermore, the switching magnetic base 15 can be a magnetically adjustable magnetic switch. During initial fixing, the magnetic force can be reduced to facilitate adjustment of the position of the magnetic base. After adjustment, the magnetic force can be increased to ensure the firmness of the magnetic fixation of the device.

[0046] The fixed housing 2 contains a frame on which the fixed magnet 14 and the switch magnetic base 15 can be fixed. The switch magnetic base 15 is equipped with a switch handle 10, and a fixed handle 3 is installed on the fixed housing 2 on one side of the fixed magnet 14. When the device needs to be fixed to the switch cabinet, hold the fixed handle 3 with your left hand and the switch handle 10 with your right hand to initially magnetically attach the magnetic base to the position of the corresponding trip switch on the switch cabinet. Then adjust the position of the magnetic base so that the sleeve 1 is directly facing the trip switch. After adjustment, you can operate the switch handle 10 to increase the magnetic force of the switch magnetic base 15 so that the device is firmly magnetically attached to the switch cabinet. Then rotate the adjusting sleeve 12 to adjust the distance between the sleeve 1 and the switch cabinet.

[0047] See Figure 1 and Figure 12 The detailed operating procedure of the remote emergency tripping device improved in this application is as follows: Inspection device: In no-load condition, check if the battery is installed; swing the lever 9 up and down to check if the sleeve 1 always rotates counterclockwise; rotate the right suction force switch handle 10 and reset it; toggle the safety switch 7 left and right to reset it to the left non-linkage state; turn on the power and observe the power display; observe the indicator light (yellow, indicating that the power is on).

[0048] No-load operation: When everything is normal under no-load conditions, move the linkage safety switch 7 to the right to put it in the linkage state and keep the power on; at this time, the indicator light is yellow; press the first button on the remote control to start the equipment; at this time, the indicator light is red; the pneumatic support rod 19 in the sleeve 1 extends out of the top pressure rod and will quickly retract after the stroke is completed; at this time, the indicator light turns green; the operation stops and a completion message is displayed; turn off the power and move the linkage safety switch 7 to the left to release the linkage.

[0049] Adsorption operation: Observe the height of the circuit breaker to be unlocked on the switch cabinet, rotate the adjusting sleeve 12 to make a fine adjustment of the height, and adjust the height of the sleeve head 1; confirm that the linkage safety switch 7 is in the non-linkage state on the left; hold the fixed handle 3 with your left hand and the suction force-enhancing switch handle 10 with your right hand, align the sleeve head 1 with the circuit breaker to be unlocked, and perform suction; after the whole machine is suctioned, rotate the right-hand suction force-enhancing switch handle 10 to increase the suction force.

[0050] Unlocking procedure: Swing the lever 9 up and down to rotate the sleeve 1 counterclockwise to unlock the trip switch.

[0052] Remote control press: Move away from the device and press the first row of buttons on the remote control. The device will start, and the power indicator light will turn from yellow to red. After the operation is complete, the power indicator light will turn green. Confirm that the circuit breaker tripped successfully.

[0053] The third row of buttons on the remote control is the backup operation button.

[0054] Shut down and uninstall: Turn off the power, turn the linkage safety switch 7 to the left to release the linkage, release the magnetic attraction of the switch base, and reduce the attraction force on the right side; at this time, hold the machine with both hands and pull it up with your right hand to detach the whole machine.

[0055] Troubleshooting common anomalies: When the device is powered off, it can be powered by an external power source in an emergency. It can use a DC power source between 11V and 15V. The interface of this device is a DC-5.5mm×2.5mm female connector.

[0056] The pressing action repeats without indicating completion; you need to manually press the second row of buttons on the remote control (the middle stop button) to stop it.

[0057] Abnormal operation, no-load operation, and manual stop may cause the linkage safety to lock and become unmovable. Try running it for 1 to 2 seconds in no-load mode and then manually press the middle stop button on the remote control to release it.
