[0032] The present invention will be further described in detail below with reference to embodiments:

[0033] like Figure 1-6As shown, the present invention provides a circuit breaker monitoring device and method for electrical safety protection, including a fixing component 1, an actuation component 2, a control component 3, and a circuit breaker component 4. The fixing component 1 connects the device to the circuit breaker component 4, and the actuation component 2 and the control component 3 are installed and fixed. The actuation component 2 transmits the actions generated by the circuit breaker body 40, and the control component 3 displays the actions generated by the circuit breaker body 40 more intuitively and transmits the action information remotely. The circuit breaker component 4 includes the circuit breaker body 40 and the circuit breaker lever 41.

[0034] like Figure 2 As shown, the fixing component 1 is fixedly installed on the outside of the circuit breaker component 4. The fixing component 1 includes a first protective shell 10 and a protective cover plate 12. The protective cover plate 12 is fixedly installed on the front of the first protective shell 10. Fixing bolts 11 are threaded on both sides of the first protective shell 10. The ends of the fixing bolts 11 are movably connected to the outside of the circuit breaker body 40. By rotating the fixing bolts 11, the ends of the fixing bolts 11 are brought into contact with the circuit breaker body 40, and the device is fixed on the circuit breaker body 40.

[0035] like Figure 3 and Figure 4 As shown, a fixing plate 13 is fixedly connected inside the first protective shell 10, through which the micro switch 33 is installed. A partition 14 is fixedly connected inside the first protective shell 10, through which the information transmission module 31 is separated from other components to prevent interference with the operation of the information transmission module 31.

[0036] like Figure 1 and Figure 2 As shown, the top and bottom of the first protective shell 10 are provided with mounting bases 15, through which the transmission connecting rod 22 is installed and the transmission connecting rod 22 can rotate in the mounting base 15. The top and bottom of the first protective shell 10 are fixedly installed with second protective shells 16, through which the actuating component 2 is protected and prevented from being damaged by impact.

[0037] like Figure 2 , Figure 3 and Figure 6As shown, the actuating component 2 is movably installed inside the fixed component 1. The actuating component 2 includes a first movable link 20, a transmission link 22, a second movable link 23, a third movable link 26, and a fourth movable link 29. The first movable link 20, the second movable link 23, the third movable link 26, and the fourth movable link 29 are all movably installed inside the first protective shell 10. The first movable link 20 and the second movable link 23 are located on the top of the first protective shell 10. The transmission link 22 is rotatably installed inside the mounting base 15. One end of the transmission link 22 is movably installed inside the first movable link 20, and the other end of the transmission link 22 is movably installed inside the second movable link 23. The first movable link 20 is located on the circuit breaker lever 41. Above, movable ball bearings 21 are movably installed inside the first movable link 20 and the third movable link 26. The movable ball bearings 21 are movably connected to the outside of the circuit breaker lever 41. The other ends of the second movable link 23 and the fourth movable link 29 are fixedly installed with contact plates 25. When the circuit breaker lever 41 is pushed upward, the circuit breaker lever 41 will contact the movable ball bearings 21 in the first movable link 20 and push the first movable link 20 upward. When the first movable link 20 moves upward, it will cause the transmission link 22 to rotate in the mounting base 15, causing the other end of the transmission link 22 to move downward and drive the second movable link 23 to move downward in the first protective shell 10, so that the contact plate 25 at the bottom of the second movable link 23 contacts the micro switch 33.

[0038] like Figure 2 , Figure 3 and Figure 6 As shown, the third movable link 26 and the fourth movable link 29 are located at the bottom of the first protective housing 10. The third movable link 26 is located below the circuit breaker lever 41. When the circuit breaker lever 41 moves downward, it contacts the movable ball 21 on the third movable link 26 and presses down the third movable link 26, causing it to move downward. The action is then transmitted to the fourth movable link 29 through the transmission link 22, causing the fourth movable link 29 to move upward in the first protective housing 10. This causes the contact plate 25 at the top of the fourth movable link 29 to contact the micro switch 33 on the lower side of the fixed plate 13.

[0039] like Figure 3 and Figure 6 As shown, a tension return spring 24 is provided on the outside of the second movable link 23. The top of the tension return spring 24 is fixedly installed inside the first protective shell 10. When the circuit breaker lever 41 moves downward, the second movable link 23 moves upward under the action of the tension return spring 24, causing the micro switch 33 below the second movable link 23 to disconnect.

[0040] like Figure 5 and Figure 6As shown, a counterweight 27 is fixedly installed on the outside of the fourth movable link 29, and a limit ring 28 is provided on the outside of the third movable link 26. The limit ring 28 is located below the first protective shell 10. When the circuit breaker lever 41 moves upward, the counterweight 27 causes the fourth movable link 29 to move downward, and the limit ring 28 restricts the movement of the third movable link 26, causing the micro switch 33 above the fourth movable link 29 to open.

[0041] like Figure 2 and Figure 6 As shown, the control component 3 is fixedly installed inside the fixed component 1. The control component 3 includes a control board 30, an information transmission module 31, a first indicator light 34, a second indicator light 35, and a buzzer 36. The first indicator light 34, the second indicator light 35, and the buzzer 36 are all electrically connected to the control board 30. A micro switch 33 is located below the contact plate 25. The first indicator light 34, the second indicator light 35, and the buzzer 36 are all fixedly installed inside the protective cover 12. The second indicator light 35 and the buzzer 36 are located below the first indicator light 34. The micro switch 33 and the control board 30 enable the first indicator light 34, the second indicator light 35, and the buzzer 36 to work. Under the combined action of the first indicator light 34, the second indicator light 35, and the buzzer 36, prompts are provided for the staff's inspection, enabling the staff to quickly find the circuit breaker that has activated and reduce inspection time.

[0042] like Figure 3 and Figure 4 As shown, the control board 30 and the information transmission module 31 are both fixedly installed inside the first protective shell 10. An information transmission interface 32 is provided on one side of the first protective shell 10. The signal transmission line is connected to the information transmission module 31 through the information transmission interface 32. The control board 30 and the information transmission module 31 transmit the action information remotely through the signal transmission line. With the joint action of the control board 30 and the information transmission module 31, the staff can know the working status of the circuit breaker body 40 without going to the site, thus improving the ease of use of the device.

[0043] like Figure 6 As shown, micro switches 33 are fixedly installed on both the upper and lower sides of the fixed plate 13. The micro switches 33 are electrically connected to the control board 30. When the micro switches 33 are turned on or off, the control board 30 will cause the first indicator light 34, the second indicator light 35 and the buzzer 36 to produce corresponding actions.

[0044] like Figure 7 As shown, a circuit breaker monitoring method for electrical safety protection is characterized by:

[0045] S1. Device installation: Connect the circuit breaker body to the circuit to be monitored. After the circuit breaker body is installed, fix the device on the circuit breaker body with fixing bolts 11 and make the movable ball on the first movable link contact the circuit breaker lever on the circuit breaker body.

[0046] S2. Action monitoring: When the circuit breaker lever on the circuit breaker body moves, the action component transmits the action of the circuit breaker lever to the micro switch, causing the micro switch to turn on or off, and causing the component to perform the corresponding action.

[0047] S3. Action Response: By turning the micro switch on and off, the first indicator light, the second indicator light, and the buzzer will be stopped or started respectively, and the operator will be alerted when inspecting the circuit breaker body.

[0048] S4. Signal Transmission: When the first indicator light, the second indicator light, and the buzzer activate, the information transmission module and the information transmission interface remotely transmit the activation information, enabling staff to promptly learn about the activation status of the circuit breaker and take appropriate action.

[0049] The working principle of the circuit breaker monitoring device and method used for electrical safety protection will be explained in detail below.

[0050] like Figure 1-7 As shown, when using the circuit breaker monitoring device and method for electrical safety protection, firstly, the circuit breaker body 40 is connected to the circuit to be monitored. After the circuit breaker body 40 is installed, the first protective shell 10 is fixedly installed on the circuit breaker body 40 by fixing bolts 11. Then, the circuit breaker lever 41 is moved to connect the circuit breaker body 40, and the signal transmission line is connected to the information transmission module 31 through the information transmission interface 32. When the circuit breaker lever 41 is moved upward, the circuit breaker lever 41 will contact the movable ball 21 in the first movable connecting rod 20. The first movable link 20 is pushed upward, and when the first movable link 20 moves upward, the transmission link 22 will rotate in the mounting base 15, causing the other end of the transmission link 22 to move downward, and driving the second movable link 23 to move downward in the first protective shell 10, so that the contact plate 25 at the bottom of the second movable link 23 contacts the micro switch 33, causing the micro switch 33 to close, and the first indicator light 34 to work through the control board 30. At the same time, the working status of the circuit breaker body 40 is remotely transmitted by the control board 30 and the information transmission module 31 through the signal transmission line.

[0051] When the switch in the circuit breaker body 40 actuates, the circuit breaker lever 41 moves downward, and under the action of the tension return spring 24, the second movable link 23 moves upward, causing the micro switch 33 below the second movable link 23 to open. The first indicator light 34 then activates accordingly. Simultaneously, the circuit breaker lever 41 contacts the movable ball 21 on the third movable link 26 and presses down the third movable link 26, causing it to move downward. This movement is then transmitted to the fourth movable link 29 via the transmission link 22, causing the fourth movable link 29 to move upward within the first protective housing 10. This causes the contact plate 25 at the top of the fourth movable link 29 to contact the micro switch 33 on the lower side of the fixed plate 13, closing the micro switch 33. This is achieved by the first movable link 20, the transmission link 22, the second movable link 23, the third movable link 26, and the fourth movable link 29. The moving link 29 transmits the action of the circuit breaker lever 41 on the circuit breaker body 40 and then transmits the action to the micro switch 33. Through the mechanical connection of the components, the action is transmitted, improving the reliability and service life of the device. The control board 30 activates the second indicator light 35 and the buzzer 36. With the combined action of the first indicator light 34, the second indicator light 35, and the buzzer 36, prompts are provided for the staff to check, enabling them to quickly find the circuit breaker that has activated, reducing inspection time and improving work efficiency. At the same time, the control board 30 and the information transmission module 31 transmit the action information remotely through the signal transmission line. With the combined action of the control board 30 and the information transmission module 31, the staff can know the working status of the circuit breaker body 40 without going to the site, improving the ease of use of the device.

[0052] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
