Description

Technical Field

[0001] The present invention belongs to the technical field of circuit breakers, and in particular relates to a circuit breaker that prevents accidental touching. Background Art

[0002] An electrical circuit breaker is a device in the electrical field. It is a switching device that can close, carry and interrupt the current under normal circuit conditions and can close, carry and interrupt the current under abnormal circuit conditions within a specified time. Therefore, circuit breakers play an important role in the electrical field.

[0003] Currently, when conducting circuit maintenance, additional personnel are required to supervise the circuit breaker. If there is no one to supervise, other personnel may accidentally touch and open the switch during the circuit maintenance process, which is unsafe.

[0004] Chinese patent publication number CN 218730718 U discloses a circuit breaker that prevents accidental touches. The circuit breaker includes a body, a retaining member, and a locking mechanism. The body is equipped with multiple operating members. When the operating members are flipped in a first direction, the body is in a closed state. When the operating members are flipped in a second direction opposite to the first direction, the body is in an open state. The retaining member is slidably mounted on the body and has a retaining position and an escape position during sliding. When the retaining member is in the escape position, the retaining member does not interfere with the flipping of the operating member in the first or second direction. When the retaining member is in the retaining position, at least a portion of the retaining member blocks the side of the operating member after it has flipped in the second direction, thereby preventing the operating member from flipping in the first direction. The locking mechanism is disposed between the body and the retaining member and is used to lock the retaining member in the retaining position or the escape position. This utility model can effectively prevent other personnel from closing the circuit breaker body while the circuit is under maintenance.

[0005] However, the existing technology has many shortcomings when used: First, the structure lacks flexibility: The coordination between the stop and the locking mechanism is relatively fixed, and the switch between the stop and avoidance positions can only be achieved by sliding. This makes it difficult to adapt to the diverse operating requirements of circuit breakers of different models and sizes, resulting in poor versatility. Furthermore, the stop only prevents the operating unit from flipping in a single direction. If the operating unit's movement needs to be restricted in all directions during maintenance, this structure cannot meet the requirements. Second, the technology lacks intelligence: it relies on manual operation to switch the position of the stopper and a locking mechanism for mechanical locking. It lacks real-time monitoring and intelligent response to the external environment or operating status. For example, it cannot automatically distinguish between accidental touches and normal operation, nor can it dynamically adjust the anti-accidental touch strategy based on actual conditions. If the locking mechanism fails, the anti-accidental touch function will be completely ineffective. Third, operational convenience is poor: During normal operation, the operator must manually switch the stopper from the blocking position to the avoidance position before operating the circuit breaker. This cumbersome process increases operation time and labor costs. Especially in emergency situations, the complex operation steps may delay troubleshooting. Summary of the Invention

[0024] like Figure 1-Figure 5 As shown, a circuit breaker for preventing accidental touch, comprising: A circuit breaker body 1, wherein a protrusion 2 is provided on the surface of the circuit breaker body 1, and an operating portion 3 for operating the circuit breaker body 1 is provided on the protrusion 2; A mounting seat 4 is provided on the raised portion 2, and a mounting groove 5 and a first oil groove 6 are provided in the mounting seat 4. An oil pushing and receiving device 7 is installed in the mounting groove 5, and an oil pushing and receiving member 8 is provided at the driving end of the oil pushing and receiving device 7. The oil pushing and receiving member 8 is provided in the first oil groove 6, and the oil pushing and receiving member 8 is movably sealed with the first oil groove 6; The telescopic locking member 9 includes a cylinder body 10 and a piston member 11 arranged in the cylinder body 10. A locking rod 12 is installed on one side of the piston member 11. The cylinder body 10 is rotatably connected to the mounting seat 4 through a rotating connecting pipe 13, and the inner cavity of the cylinder body 10 is connected to the inner cavity of the first oil tank 6 through the rotating connecting pipe 13.

[0025] The present invention utilizes the mounting base 4, mounting slot 5, first oil tank 6, oil push-and-receive device 7, and oil push-and-receive member 8 to construct a transmission system based on hydraulic principles. When the oil push-and-receive device 7 is in operation, for example, the lifting plate 17 is driven by the lifting drive 16. The lifting plate 17 converts linear motion into linear reciprocating motion of the oil push-and-receive member 8 within the first oil tank 6 via the connecting rod 19. Because the oil is incompressible, the movement of the oil push-and-receive member 8 within the first oil tank 6 pushes the oil, causing it to enter the cylinder 10 through the rotating connecting tube 13. At this point, the oil pushes the piston 11 within the cylinder 10, which in turn drives the locking rod 12 to extend and retract.

[0026] When the circuit breaker's operating state needs to be locked, the oil pushing and retracting device 7 pushes the oil into the cylinder 10. The piston 11, under the action of the oil pressure, drives the locking rod 12 to extend. The engaging block 26 at the end of the locking rod 12 engages the outside of the operating portion 3, restricting the movement of the operating portion 3 and preventing the circuit breaker from malfunctioning due to accidental contact. When the circuit breaker needs to be operated, the oil pushing and retracting device 7 moves in the opposite direction, recovering the oil. The oil in the cylinder 10 flows back, and the piston 11 drives the locking rod 12 to retract, unlocking the operating portion 3. During this process, the rotating connection method of the rotating connecting tube 13 ensures that the cylinder 10 can flexibly rotate to adapt to the direction of force when the oil pressure changes, maintaining the stability of the telescopic locking member 9 during operation, avoiding damage to components due to external forces or internal pressure changes, and ensuring the reliable implementation of the anti-accidental touch function. Through such a complete set of hydraulic transmission and locking mechanisms, not only is the stable transmission and control of power achieved, but the anti-accidental touch performance of the circuit breaker is also significantly enhanced, improving the safety and reliability of the equipment.

[0027] As a preferred example of the present application, the mounting groove 5 is provided in the middle portion of the mounting seat 4, the first oil groove 6 is located below the mounting seat 4, and a rotation groove 14 is provided on both sides of the bottom of the mounting seat 4. One end of the rotation connecting tube 13 is rotatably mounted on a side wall of the rotation groove 14 away from the first oil groove 6 via a bearing, and the other end of the rotation connecting tube 13 is movably passed through a side wall of the rotation groove 14 close to the first oil groove 6 via a sealed bearing 15, and extends into the first oil groove 6; The specific position distribution of the mounting groove 5 and the first oil groove 6 optimizes the spatial layout of the hydraulic system, makes the flow path of the oil in the mounting seat 4 more reasonable, and facilitates the pushing and recovery of the oil by the oil pushing and collecting device 7; the setting of the rotating groove 14, the bearing and the sealing bearing 15 ensures that the rotating connecting pipe 13 can rotate flexibly and ensure the sealing of the first oil groove 6 to prevent oil leakage, while maintaining the pressure stability of the hydraulic system, thereby ensuring the reliability and stability of the telescopic locking member 9.

[0028] As a preferred example of the present application, the oil pushing and receiving device 7 includes a lifting drive device 16, a lifting plate 17 is installed on the driving end of the lifting drive device 16, and a connecting rod 19 is rotatably installed on the side of the lifting plate 17 through a rotating shaft 18, and the other end of the connecting rod 19 is connected to the side of the oil pushing and receiving member 8 through the rotating shaft 18; The present application forms a simple and efficient mechanical transmission mechanism through the cooperation of the lifting drive device 16, the lifting plate 17, the connecting rod 19 and the oil body pushing and receiving member 8, which can convert the linear motion of the lifting drive device 16 into the linear reciprocating motion of the oil body pushing and receiving member 8 in the first oil tank 6, thereby realizing the precise pushing and control of the oil body, and then accurately controlling the extension and retraction of the locking rod 12 in the telescopic locking member 9, providing a stable and reliable power source for the anti-accidental touch locking and unlocking operations of the circuit breaker.

[0029] As a preferred example of the present application, the oil pushing and receiving member 8 includes a main frame 20, a piston sealing layer 21 is provided on the outer side of the main frame 20, and the main frame 20 is movably sealed with the first oil groove 6 through the piston sealing layer 21; The present application ensures good sealing performance between the oil push-and-receive member 8 and the first oil groove 6 through the piston sealing layer 21 on the outside of the main frame 20, preventing oil from leaking from the gap between the two and maintaining the normal working pressure of the hydraulic system; at the same time, the piston sealing layer 21 can also reduce the friction resistance of the oil push-and-receive member 8 when it moves in the first oil groove 6, making the movement of the oil push-and-receive member 8 smoother, thereby improving the working efficiency and stability of the entire hydraulic transmission system.

[0030] As a preferred example of the present application, an oil-blocking and breathable membrane 22 is installed inside the main frame 20, which allows gas to pass through the oil-blocking and breathable membrane 22 and enter the first oil tank 6; The present application realizes intelligent switching of the state of the locking rod 12 through the linkage mechanism between the oil-blocking and breathable membrane 22 and the gas and oil. When the gas is pushed out, the oil fills the space and pushes the locking rod 12 to lock the operating part 3, preventing the locking rod 12 from being accidentally touched and causing the operation; when the gas enters, the oil flows back to unlock the locking rod 12. At the same time, the retained resistance prevents the accidental operation caused by slight touch, thereby ensuring the operational flexibility and further strengthening the anti-accidental touch function. Specifically, after the oil-blocking, breathable membrane 22 is installed within the main frame 20, an intelligent linkage mechanism is established between the gas, the oil, and the locking rod 12. When the circuit breaker is locked, the oil in the first oil tank 6, driven by the oil pushing and retracting device 7, pushes the piston 11 in the cylinder 10 via the rotating connecting tube 13, extending the locking rod 12 and locking the operating unit 3 via the engaging block 26. At this point, the space within the first oil tank 6 is relatively stable, and the oil-blocking, breathable membrane 22 isolates the oil, maintaining internal pressure equilibrium. When the operating part 3 needs to be unlocked, the outside gas enters the first oil tank 6 through the oil-blocking and breathable membrane 22. Due to the entry of gas, the pressure in the first oil tank 6 increases, and under the action of the pressure difference, the oil begins to flow back. The oil flows back to the first oil tank 6 from the cylinder body 10 through the rotating connecting pipe 13, the pressure in the cylinder body 10 decreases, the piston member 11 drives the locking rod 12 to retract, and the operating part 3 is unlocked. During the gas entry process, the oil-blocking and breathable membrane 22 plays a key role. It allows gas to pass through while preventing the oil from leaking out, ensuring the sealing of the hydraulic system. In addition, after the gas enters, although the operating part 3 is unlocked, the oil still retains a certain resistance in the hydraulic system after flowing back. The operator needs to apply a certain amount of force to operate the circuit breaker, which effectively avoids misoperation caused by slight touch or accidental touch, and greatly enhances the anti-accidental touch performance while ensuring operational flexibility. When the operating part 3 needs to be relocked, the oil pushing and retracting device 7 is activated, pushing the oil back into the cylinder 10, the piston 11 pushes the locking rod 12 out, and the clamping block 26 clamps the operating part 3 again. At the same time, the excess gas in the first oil tank 6 is discharged through the oil-blocking breathable membrane 22, maintaining the internal pressure balance, and the entire system returns to the locked state. Through this linkage mechanism between the oil-blocking breathable membrane 22 and the gas and oil, the intelligent switching of the locking rod 12 state is achieved, allowing the circuit breaker to switch freely between locking and unlocking, while always maintaining a reliable anti-accidental touch effect, providing a strong guarantee for the safe and stable operation of the circuit breaker.

[0031] As a preferred example of the present application, a pipe 23 is installed on the side of the main frame 20 close to the connecting rod 19, and a solenoid valve 24 is provided on the pipe 23; This application establishes a controllable gas flow channel through a pipe 23 and a solenoid valve 24 installed on one side of the main frame 20. By controlling the opening and closing of the solenoid valve 24, the amount and flow rate of gas entering the first oil tank 6 can be precisely adjusted, thereby more accurately controlling the movement of the oil, achieving refined operation of the extension and retraction of the locking rod 12, and improving the accuracy and stability of the anti-inadvertent touch system response.

[0032] As a preferred example of the present application, the cylinder body 10 is arranged in an arc shape, and the end of the locking rod 12 away from the cylinder body 10 is rotatably connected to a clamping block 26 through a shaft 25, and the clamping block 26 is connected to the outside of the operating part 3 in a clamping manner; The present application conforms to the principles of mechanics through the design of the arc-shaped cylinder body 10, which is conducive to the uniform distribution of hydraulic pressure in the cylinder body 10 and ensures the smooth movement of the piston 11 and the locking rod 12; the clamping method of the clamping block 26 and the operating part 3 enables the locking rod 12 to reliably limit the movement of the operating part 3, and the rotational connection of the shaft rod 25 gives the clamping block 26 a certain degree of adjustment freedom, which can not only lock tightly, but also adapt to slight deformation of the operating part 3, thereby enhancing the reliability and applicability of the locking structure.

[0033] As a preferred example of the present application, a flexible film pressure sensor 27 is provided on the outer surface of the clamping block 26, and the signal output end of the flexible film pressure sensor 27 is connected to the signal input end of the lifting drive device 16 via the control processor; With a flexible film-type pressure sensor 27 installed on the outer surface of the clamping block 26, the circuit breaker's accidental touch prevention function establishes an intelligent pressure monitoring and response system. In the circuit breaker's normally locked state, the locking rod 12 engages the operating unit 3 via the clamping block 26. At this point, the clamping block 26 experiences only slight static pressure. The flexible film-type pressure sensor 27 converts this pressure signal into an electrical signal and transmits it to the control processor. The control processor compares this signal with a preset pressure threshold. Because this pressure is at a low level in the normally locked state, the control processor does not issue any commands to the lift drive 16. The lift drive 16 remains stationary, and the locking rod 12 remains firmly locked. Once external force is applied to the clamping block 26, the flexible film pressure sensor 27 captures the pressure change in real time and quickly transmits the changed pressure signal to the control processor. If the control processor determines that the pressure is an unexpected false touch (generally a small force below the preset unlocking threshold), it will not send an action command to the lifting drive 16, and the locking rod 12 will remain locked, effectively preventing the circuit breaker from malfunctioning due to accidental touch. When the operator applies a force to the operating unit 3, intending to operate the circuit breaker normally, the pressure on the engaging block 26 gradually increases. When the pressure exceeds the preset unlocking threshold, the control processor receives this signal, immediately analyzes and processes it, and issues an unlocking command to the lifting drive 16. The lifting drive 16 then activates, driving the oil pushing and retracting device 7, which changes the oil distribution within the first oil tank 6, causing it to flow back. This in turn pushes the piston 11, which in turn retracts the locking rod 12, unlocking the operating unit 3. Throughout this process, the flexible film pressure sensor 27, with its high sensitivity, accurately senses subtle pressure changes. The control processor rapidly analyzes and determines the pressure signal based on preset logic, precisely regulating the movement of the lift drive 16 and achieving intelligent dynamic adjustment of the state of the locking lever 12. This intelligent mechanism not only effectively prevents circuit breaker misoperation caused by accidental contact but also rapidly responds to normal operator operation, ensuring both safe equipment operation and enhanced operational convenience and efficiency.

[0034] As a preferred example of the present application, the mounting seat 4 is detachably connected to the raised portion 2 via a bolt 29; The present application uses a detachable connection between the mounting base 4 and the raised portion 2 through the bolt 29, which facilitates the disassembly and installation of the mounting base 4. Whether in the product assembly process or in later maintenance, inspection or replacement of parts, it can significantly improve operational efficiency and reduce maintenance costs; at the same time, the detachable structure also provides convenience for product upgrades and modifications, enhancing the versatility and scalability of the product.

[0035] As a preferred example of the present application, a second pressure sensor 28 is provided between the mounting seat 4 and the raised portion 2, and a signal output end of the second pressure sensor 28 is connected to an alarm via a control processor; The present application uses a second pressure sensor 28 to monitor the pressure changes between the mounting base 4 and the protrusion 2 in real time. Once abnormal pressure is detected (such as a sudden change in pressure due to external impact, looseness, etc.), the signal is triggered by the control processor to trigger the alarm, promptly reminding the staff that there is an abnormal situation in the equipment, facilitating rapid troubleshooting, avoiding circuit breaker performance degradation or misoperation due to installation structure problems, and effectively improving the safety and reliability of equipment operation.

[0036] In summary, the present invention constructs a transmission system based on the hydraulic principle by setting up the mounting seat 4, the mounting groove 5, the first oil groove 6, the oil body pushing and receiving device 7 and the oil body pushing and receiving member 8, which can realize the stable transmission and control of power; the telescopic locking member 9 is connected to the mounting seat 4 through the rotating connecting tube 13, and the hydraulic drive piston member 11 and the locking rod 12 are extended and retracted to realize the locking or unlocking of the circuit breaker operating state, further enhancing the anti-accidental touch function, and the rotating connection mode of the rotating connecting tube 13 ensures the flexibility and stability of the telescopic locking member 9 during operation; after the oil-proof and breathable membrane 22 is installed inside the main frame 20, an intelligent linkage working mechanism is formed between the gas and the oil body and the locking rod 12. When the circuit breaker is in the locked state, the oil body in the first oil groove 6, under the action of the oil body pushing and receiving device 7, pushes the piston member 11 in the cylinder body 10 through the rotating connecting tube 13, so that the locking rod 12 extends and locks the operating part 3 through the clamping block 26. At this point, the space within first oil tank 6 is relatively stable, with oil-blocking, breathable membrane 22 isolating the oil and maintaining internal pressure balance. Flexible film pressure sensor 27, with its high sensitivity, can accurately sense subtle pressure changes. The control processor rapidly analyzes and determines the pressure signal based on preset logic, precisely regulating the movement of lift drive 16 and enabling intelligent, dynamic adjustment of the locking lever 12. This intelligent mechanism not only effectively prevents circuit breaker misoperation caused by accidental contact but also rapidly responds to normal operator operation, ensuring both safe equipment operation and enhanced operational convenience and efficiency.
