Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and particularly to a distribution control circuit breaker with alarm and safety protection functions. Background Technique

[0002] A circuit breaker refers to 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. It is divided into high-voltage circuit breakers and low-voltage circuit breakers according to its application scope. Circuit breakers can be used to distribute electric energy, start asynchronous motors without frequent starting, protect power supply lines and motors, etc. When they encounter serious overload, short circuit, undervoltage and other faults, they can automatically cut off the circuit, and its function is equivalent to the combination of a fuse switch and an over- and under-thermal relay, etc. Generally, no components need to be changed after interrupting the fault current. At present, it has been widely used.

[0003] In "electricity-related" work, operations must be carried out in accordance with the corresponding electrical safety operating procedures. For example, when performing maintenance work on electrical circuits or electrical equipment, on the basis of normal opening and power-off of the switch, generally, safety procedures such as "hanging a warning sign" or "locking" are also required at the switch position to ensure the personal safety of relevant staff. Without this safety guarantee link, there may be "mis-power-on" and the resulting potential hazards in certain special situations (for example, the maintenance work location may be far from the power-off switch location, and non-maintenance personnel or other uninformed personnel may mistakenly think that the power-off switch tripped automatically and randomly re-close the switch). Existing circuit breakers cannot automatically distinguish whether the power-off is due to a circuit problem and tripped automatically or due to manual power-off by maintenance personnel when powering off, and cannot distinguish between automatic tripping and manual power-off when powering on, which is prone to misoperation and affects the safety of maintenance personnel. Therefore, a distribution control circuit breaker with alarm and safety protection functions is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a distribution control circuit breaker with alarm and safety protection functions that is convenient for automatically distinguishing the cause of power-off, can issue an alarm according to different power-off situations, and avoid mis-closing during the maintenance process, so as to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present invention provides the following technical solutions: A distribution control circuit breaker with alarm and safety protection functions, including a housing, a control mechanism, a breaking mechanism, and an alarm mechanism.

A rotating wheel is fixedly connected to the rotating shaft, and a control lever is fixedly connected to the rotating wheel. The control lever is rotatably fitted with the inner wall of the rotating groove, and is used to control the rotation and tripping of the control lever according to the circuit conditions. The breaking mechanism includes a control rod installed on the control lever, which is used to avoid the need to control the control rod to close when the control mechanism automatically controls the circuit to trip. When manually controlling the rotation of the control lever, the control rod needs to be pressed before the rotation operation. The alarm mechanism includes an alarm fixedly installed on the housing, which is used to emit an alarm when the circuit automatically powers off and trips, reminding of the circuit tripping situation. At this time, manually pushing the control lever to close will not emit an alarm. When manually controlling the rotation of the control lever to cut off the power, no alarm will be emitted during the power-off process. At this time, when manually pushing the control lever to close, an alarm will be emitted first, reminding people that the power-off is manually controlled and not an automatic trip, facilitating the automatic distinction of the power-off reason and being able to emit an alarm according to different power-off situations, avoiding misclosing during the maintenance process.

[0006] Preferably, the control mechanism includes a driving rod rotatably connected to the inner wall of the device cavity. A rectangular frame is rotatably connected to the rotating wheel. A tension spring fixedly connected to the inner wall of the device cavity is fixedly connected to the driving rod. A controller is provided in the device cavity, which is used to push one end of the driving rod upward when a circuit failure occurs, so that the other end of the driving rod presses down the rectangular frame, facilitating the control of the rotation and tripping of the control lever according to the circuit conditions.

[0007] Preferably, the breaking mechanism further includes a first spring fixedly installed at one end of the control rod. A control groove slidably connected to the outer wall of the control rod is provided in the control lever. One end of the first spring is fixedly connected to the control groove. Guide members for guiding the rotation state of the control lever are provided on both sides of the rotating groove, facilitating the avoidance of the need to control the control rod to close when the control mechanism automatically controls the circuit to trip. When manually controlling the rotation of the control lever, the control rod needs to be pressed before the rotation operation.

[0008] Preferably, the guiding member includes guiding rods fixedly installed on both sides of the control rod. Guiding grooves for slidably connecting with the guiding rods are formed on both sides of the operating rod. First arc-shaped grooves and second arc-shaped grooves capable of slidably connecting with the outer wall of the guiding rods are formed on both sides of the rotating groove. Communication grooves for communicating the upper ends of the first arc-shaped groove and the upper ends of the second arc-shaped groove are formed on both sides of the rotating groove. Latching grooves communicating with the bottom ends of the second arc-shaped grooves are formed on both sides of the rotating groove. Both the communication grooves and the latching grooves can slidably connect with the outer wall of the guiding rod. A control member for controlling the sliding state of the guiding rod in the first arc-shaped groove is provided on the driving rod, facilitating guiding the rotating state of the operating rod.

[0009] Preferably, the control member includes a pushing block installed on the driving rod. A limiting groove is formed on the driving rod. The pushing block is slidably connected with the inner wall of the limiting groove. A second spring fixedly connected to the limiting groove is fixedly connected to the upper side of the pushing block. The bottom of the pushing block is rotatably connected to the outer wall of the rectangular frame. A limiting member for limiting the guiding rod is provided in the first arc-shaped groove, facilitating controlling the sliding state of the guiding rod in the first arc-shaped groove.

[0010] Preferably, the limiting member includes a latching block installed in the first arc-shaped groove. A sliding groove communicating with the first arc-shaped groove is formed in the housing. The latching block is slidably connected with the inner wall of the sliding groove. One end of the latching block is fixedly connected to a third spring fixedly connected to the sliding groove. The side surface of the end of the latching block away from the third spring is designed as an inclined surface. A driving member for controlling the moving state of the latching block is provided on the driving rod, facilitating limiting the guiding rod.

[0011] Preferably, the driving member includes a connecting rope fixedly connected to the end of the latching block close to the third spring. The connecting rope penetrates the inner wall of the housing and is slidably connected with the inner wall of the housing. The end of the connecting rope away from the latching block is fixedly connected to a rotating rod. The rotating rod is rotatably connected to the side surface of the driving rod, facilitating controlling the moving state of the latching block.

[0012] Preferably, the alarm mechanism includes a first control key fixedly installed at the bottom end position of the first arc-shaped groove. A second control key is fixedly connected to the bottom end of the second arc-shaped groove. The first control key and the second control key are used to control the operating state of the alarm, facilitating giving an alarm when the circuit automatically powers off and trips, reminding of the circuit tripping situation. At this time, manually pushing the operating rod to close the switch will not give an alarm. When manually controlling the operating rod to rotate and power off, no alarm will be given during the power-off process. At this time, when manually pushing the operating rod to close the switch, an alarm will be given first, reminding people that this power-off is manually controlled and not an automatic trip.

[0013] Preferably, an anti-slip insulating pad is provided on the outer wall of the joystick, which is convenient for increasing the friction force, improving the operation stability and avoiding electric shock at the same time.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. A distribution control circuit breaker with an alarm and safety protection function provided by the present invention solves the problem that it is difficult to automatically distinguish between manual power-off and power-off due to circuit fault tripping when the existing distribution control circuit breaker is in use, resulting in easy misoperation during manual power-off maintenance and causing potential safety hazards. When the control mechanism automatically controls the circuit to trip, it is not necessary to control the control rod to close. When manually controlling the joystick to rotate, it is necessary to press the control rod before rotating. When the circuit automatically powers off and trips, an alarm is issued to remind of the circuit tripping situation. At this time, manually pushing the joystick to close will not issue an alarm. When manually controlling the joystick to rotate and power off, no alarm is issued during the power-off process. At this time, when manually pushing the joystick to close, an alarm will be issued first to remind people that the power-off is manually controlled and not an automatic trip.

[0016] 2. A distribution control circuit breaker with an alarm and safety protection function provided by the present invention, when it is necessary to close the switch after the maintenance is completed, it is necessary to press one end of the control rod again, so that the guide rod slides from the clamping groove to the bottom of the second arc groove. At this time, the second control key will be triggered to remind people that the power-off is a manual operation and caution should be exercised when closing the switch, reducing the probability of misoperation. When the inspection is correct, push the joystick upward, and the guide rod can slide to the top position in the second arc groove. After releasing the joystick, the control rod is pushed out by the second spring. During the sliding process of the guide rod in the guide groove, it slides along the communication groove to the top of the first arc groove to complete the closing and power-on operation. The device is easy to operate, can clearly judge the cause of power-off without cumbersome operation, and reduces the potential safety hazards during the maintenance process.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 10, the present invention provides a technical solution: a distribution control circuit breaker with alarm and safety protection functions, including a housing 1, a control mechanism 4, a tripping mechanism 8 and an alarm mechanism 10. A device cavity 2 is opened inside the housing 1, and a rotating groove 3 is opened on the side of the housing 1. The control mechanism 4 includes a rotating shaft 5 rotatably connected to the device cavity 2. A rotating wheel 6 is fixedly connected to the rotating shaft 5, and a control lever 7 is fixedly connected to the rotating wheel 6. An anti-slip insulating pad 38 is provided on the outer wall of the control lever 7. The control lever 7 is rotatably fitted with the inner wall of the rotating groove 3 and is used to control the rotation and tripping of the control lever 7 according to the circuit conditions. The tripping mechanism 8 includes a control rod 9 installed on the control lever 7 and is used to avoid the need to control the control rod 9 to close the switch when the control mechanism 4 automatically controls the circuit to trip. When manually controlling the rotation of the control lever 7, it is necessary to press the control rod 9 before rotating. The alarm mechanism 10 includes an alarm 11 fixedly installed on the housing 1 and is used to issue an alarm when the circuit automatically trips off, reminding of the circuit tripping situation. At this time, manually pushing the control lever 7 to close the switch will not issue an alarm. When manually controlling the control lever 7 to rotate and cut off the power, no alarm will be issued during the power-off process. At this time, when manually pushing the control lever 7 to close the switch, an alarm will be issued first, reminding people that the power-off is manually controlled and not an automatic trip.

[0030] The control mechanism 4 includes a driving rod 12 rotatably connected to the inner wall of the device cavity 2. A rectangular frame 13 is rotatably connected to the rotating wheel 6. A tension spring 14 fixedly connected to the inner wall of the device cavity 2 is fixedly connected to the driving rod 12. A controller 15 is provided in the device cavity 2 and is used to push one end of the driving rod 12 to move upward when a circuit fault occurs, so that the other end of the driving rod 12 presses down the rectangular frame 13.

[0031] The tripping mechanism 8 further includes a first spring 16 fixedly installed at one end of the control rod 9. A control groove 17 slidably connected to the outer wall of the control rod 9 is opened in the control lever 7. One end of the first spring 16 is fixedly connected to the control groove 17. Guide members 18 for guiding the rotation state of the control lever 7 are provided on both sides of the rotating groove 3.

[0032] The guide member 18 includes guide rods 19 fixedly installed on both sides of the control rod 9. Guide grooves 20 slidably connected to the guide rods 19 are opened on both sides of the control lever 7. First arc grooves 21 and second arc grooves 39 capable of slidably connecting to the outer wall of the guide rods 19 are opened on both sides of the rotating groove 3. Communication grooves 22 for communicating the upper ends of the first arc grooves 21 and the upper ends of the second arc grooves 39 are opened on both sides of the rotating groove 3. Clamping grooves 23 communicating with the bottom ends of the second arc grooves 39 are opened on both sides of the rotating groove 3. Both the communication grooves 22 and the clamping grooves 23 can slidably connect to the outer wall of the guide rods 19. A control member 24 for controlling the sliding state of the guide rods 19 in the first arc grooves 21 is provided on the driving rod 12.

[0033] The control member 24 includes a pushing block 25 mounted on the driving rod 12. A limiting groove 26 is formed in the driving rod 12. The pushing block 25 is slidably connected to the inner wall of the limiting groove 26. A second spring 27 fixedly connected to the limiting groove 26 is fixedly connected to the upper side of the pushing block 25. The bottom of the pushing block 25 is rotatably connected to the outer wall of the rectangular frame 13. A limiting member 28 for limiting the guiding rod 19 is provided in the first arc-shaped groove 21.

[0034] The limiting member 28 includes a clamping block 29 mounted in the first arc-shaped groove 21. A sliding groove 30 communicating with the first arc-shaped groove 21 is formed in the housing 1. The clamping block 29 is slidably connected to the inner wall of the sliding groove 30. A third spring 31 fixedly connected to the sliding groove 30 is fixedly connected to one end of the clamping block 29. The side surface of the end of the clamping block 29 away from the third spring 31 is designed as an inclined surface. A driving member 32 for controlling the moving state of the clamping block 29 is provided on the driving rod 12.

[0035] The driving member 32 includes a connecting rope 33 fixedly connected to one end of the clamping block 29 close to the third spring 31. The connecting rope 33 passes through the inner wall of the housing 1 and is slidably connected to the inner wall of the housing 1. A rotating rod 35 is fixedly connected to the end of the connecting rope 33 away from the clamping block 29. The rotating rod 35 is rotatably connected to the side surface of the driving rod 12.

[0036] The alarm mechanism 10 includes a first control key 36 fixedly installed at the bottom end position of the first arc-shaped groove 21. A second control key 37 is fixedly connected to the bottom end of the second arc-shaped groove 39. The first control key 36 and the second control key 37 are used to control the operating state of the alarm 11.

[0037] In this implementation scheme, when it is normally powered on and used, the joystick 7 is in an upwardly flipped state. At this time, under the pulling of the tension spring 14, the driving rod 12 pulls up the rectangular frame 13 and supports the bottom of the rotating wheel 6. When a fault such as overload or short circuit occurs in the circuit, one end of the driving rod 12 is magnetically attracted and moved upward by the controller 15, so that the driving rod 12 rotates to push the rectangular frame 13 at the other end downward, thereby driving the rotating wheel 6 to rotate around the rotating shaft 5. And under the pulling of the tension spring 14, the joystick 7 rotates to the position diagonally below in the rotating groove 3 to complete the tripping and power-off operation. This principle is the tripping principle of the existing circuit breaker and is not the innovation point of this scheme. At the same time, the detailed structure and principle of controlling the tripping operation are not elaborated too much.

[0038] It should be noted that: when the circuit fails and power is cut off, the driving source for the rotation of the joystick 7 is the driving rod 12, while in the case of manual power cut-off, the driving source is the direct action of the hand on the joystick 7. When a circuit failure occurs, one end of the driving rod 12 moves downward to push the push block 25. At this time, the joystick 7 is limited by the clamping blocks 29 on both sides to the guide rod 19, and the joystick 7 cannot directly trip. The driving rod 12 rotates and gradually compresses the second spring 27, while driving the rotating rod 35 to pull down one end of the connecting rope 33, so that the connecting rope 33 pulls the clamping block 29 to slide horizontally in the sliding groove 30, gradually releasing the blockage of the guide rod 19. After that, under the push of the push block 25, the rectangular frame 13 quickly drives the rotating wheel 6 to rotate, the joystick 7 rotates downward, and the guide rod 19 slides downward to the bottom end in the first arc groove 21 and abuts against the first control key 36, pressing the first control key 36 and triggering the alarm 11 to sound an alarm to remind people of a circuit failure.

[0039] When the circuit fails and trips, the guide rod 19 slides and is limited in the first arc groove 21. At this time, the control rod 9 cannot be pressed. When it is necessary to switch on the power after the maintenance is completed, directly push the joystick 7 to flip upward to complete the switching-on and power-on operation. During the process of the guide rod 19 sliding upward to the top end of the first arc groove 21, it will abut against the bottom slope part of the clamping block 29, gradually pushing the clamping block 29 to slide horizontally and compressing the third spring 31. Until the guide rod 19 moves upward through the clamping block 29 to the upper side area of the clamping block 29, the clamping block 29 pops out under the push of the third spring 31 to block and limit the bottom of the guide rod 19. At this time, the joystick 7 cannot be directly rotated downward manually to cut off the power to avoid misoperation.

[0040] When manual power cut-off is required to complete circuit maintenance, it is necessary to first press the top of the control rod 9 to drive the guide rod 19 to slide in the guide groove 20. The guide rod 19 slides from the top end of the first arc groove 21 through the communication groove 22 to the top end of the second arc groove 39. After that, the joystick 7 can be rotated downward so that the guide rod 19 slides to the bottom end in the second arc groove 39 and releases the joystick 7 at the bottom end. Under the push of the second spring 27, the control rod 9 pops out outward, and the guide rod 19 slides into the clamping groove 23 for clamping to complete the limitation of the joystick 7. At this time, the joystick 7 cannot be directly rotated upward to avoid potential safety hazards caused by mis-switching on during the power maintenance process.

[0041] When it is necessary to switch on the power after the maintenance is completed, one end of the control rod 9 needs to be pressed again, so that the guide rod 19 slides from the clamping groove 23 to the bottom of the second arc groove 39. At this time, the second control key 37 will be triggered, reminding people that the power-off is a manual operation and caution should be exercised when switching on the power to reduce the probability of misoperation. When the inspection is correct, push the joystick 7 upward, and the guide rod 19 can slide to the top position in the second arc groove 39. After releasing the joystick 7, the control rod 9 is pushed out by the second spring 27. During the sliding process of the guide rod 19 in the guide groove 20, it slides along the communication groove 22 to the top of the first arc groove 21 to complete the operation of switching on the power and energizing. This device is convenient to operate, can clearly judge the cause of power-off without cumbersome operations, and reduces potential safety hazards during the maintenance process.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
