Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a protection device for a circuit breaker. Background Art

[0002] One of the main functions of a circuit breaker is to expand the control range. By using a circuit breaker, a small current can be used to control the operation of a large current. When the control signal of a multi-contact circuit breaker reaches a certain specific value, it can simultaneously switch, break, or connect multiple circuits according to different forms of contact groups. This ability makes the circuit breaker play a key role in circuit control and greatly expands its application range.

[0003] Nowadays, circuit breakers are often used in our daily life. When users in a community decorate their houses, they need to control the circuit breaker to cut off all the power in the house. Generally, such circuit breakers are installed in the distribution room on the first floor, and all users install them in the same place. When one of the circuit breakers is turned off, it will not affect the electricity consumption of other households. However, to prevent the turned-off circuit breaker from being accidentally touched during decoration, resulting in electric shock to the decoration workers, and at the same time, there are many electrical equipment in the existing households. When a certain electrical equipment is short-circuited, it will cause the circuit breaker to trip directly. At this time, the circuit breaker needs to be restarted, which will take a long time and affect the life of the household. Therefore, this application proposes a protection device for a circuit breaker.

[0004] In addition, the existing patent CN203101795U discloses a radio-controlled guide rail, including a guide rail, characterized in that: it further includes a guide rail controller and a receiver installed on the motor. The guide rail controller and the receiver are connected by a radio frequency signal to transmit instructions, and the movement of the photography and imaging on the guide rail is driven by controlling the operation of the motor; the guide rail controller includes a main control module, a radio frequency emission module, a knob control module, and a shooting control module. The radio frequency emission module, the knob control module, and the shooting control module are respectively connected to the main control module. Summary of the Invention

Specific implementation mode

[0023] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0024] As Figures 1-3 shown, a protection device for a circuit breaker proposed by the present utility model includes a guide rail 1 and a support plate 3. A circuit breaker body 2 is slidably installed on the guide rail 1, and the guide rail 1 is connected to the wall through bolts. A first chute 301 is provided on the support plate 3, and a connecting plate 4 is slidably connected to the first chute 301. One end of the connecting plate 4 is fixedly connected to a protective cover 5. The protective cover 5 is in a form of three-sided wrapping for protection. The connecting plate 4 is fixed to the support plate 3 through bolts. Threaded holes are provided on the connecting plate 4, and the connection between the connecting plate 4 and the support plate 3 is tightened by bolts. The protective cover 5 fits on the switch of the circuit breaker body 2. The protective cover 5 is used to protect the switch on the circuit breaker body 2 and prevent accidental human touch;

[0025] As Figure 3 shown, a group of support blocks 6 are fixedly connected to the support plate 3. A linear motor 7 is fixedly installed on the support blocks 6. The output end of the linear motor 7 is connected to an electric slide rail 8. An electric slider 9 is slidably connected to the electric slide rail 8. The other end of the electric slide rail 8 is connected to the support block 6. A connecting block 10 is fixedly connected to the electric slider 9. A brush head 11 for cleaning the electric slide rail 8 is fixedly installed on the connecting block 10. The linear motor 7 drives the electric slider 9 to move on the electric slide rail 8. Since the electric slide rail is not used for a long time, dust will accumulate on the surface, which will affect the movement of the electric slider 9 over time. The movement of the electric slider 9 drives the connecting block 10 and the brush head 11 to move, so as to clean the electric slide rail 8 during the movement of the electric slider 9.

[0026] As Figure 3As shown, a group of fixing blocks 303 are fixedly connected to the support plate 3. The two fixing blocks 303 are connected to the wall through bolts. The support plate 3 is installed above the circuit breaker body 2. After adjusting the position, it is fixed to the wall through bolts.

[0027] As Figure 4 shown, a second sliding groove 302 is formed on the support plate 3. A fixing plate 901 is fixedly connected to the electric slider 9. A sliding block 902 is fixedly connected to the fixing plate 901. The sliding block 902 is slidably fitted on the second sliding groove 302. The bottom surface of the sliding block 902 is fixedly connected to an electric push rod 903. One end of the electric push rod 903 is fixedly connected to a pushing block 904. The electric slider 9 can drive the sliding block 902, the electric push rod 903 and the pushing block 904 to move. By extending the electric push rod 903, the pushing block 904 is driven to move downward, which is used to open the closed switch on the tripped circuit breaker body 2.

[0028] As Figure 3 shown, a side plate 12 is fixedly connected to one side of the electric slider 9. A position sensor 13 is fixedly installed on the side plate 12. The position sensor 13 is a grating reading head. A grating main scale 14 is fixedly installed on the support plate 3. The position sensor 13 is located vertically above the grating main scale 14. A controller 15 is fixedly installed on the support plate 3. The controller 15 includes a signal receiving module. The controller 15 is electrically connected to the linear motor 7. The controller 15 is electrically connected to the position sensor 13. Among them, the controller 15, the linear motor 7, and the position sensor 13 are all externally powered. When the electric slider 9 drives the grating reading head to move on the grating main scale 14, the grating reading head can read the moving distance, and then send an electrical signal to the controller 15, and then adjust the electric slider 9 so that the sliding block 902 can stay at a specified position.

[0029] In this embodiment, first, the length of the circuit breaker body 2 is measured, then the installation position of the support plate 3 is adjusted, and then the support plate 3 is fixed to the wall. When one of the circuit breaker bodies 2 needs to be closed for a long time, first, the connecting plate 4 is sleeved on the first sliding groove 301 on the support plate 3, and then it moves on the first sliding groove 301 to drive the connecting plate 4 and the protective cover 5 to move. After moving to the specified circuit breaker body 2, the connecting plate 4 is fixed through bolts. Under the action of the protective cover 5, the circuit breaker body 2 can be prevented from being accidentally touched. Then, by starting the linear motor 7, the electric slider 9 is driven to move on the electric slide rail 8. The electric slider 9 can drive the sliding block 902, the electric push rod 903 and the pushing block 904 to move. By extending the electric push rod 903, the pushing block 904 is driven to move downward, which is used to open the closed switch on the tripped circuit breaker body 2. The movement of the electric slider 9 drives the connecting block 10 and the brush head 11 to move, so as to clean the electric slide rail 8 during the movement of the electric slider 9.

[0030] The above specific embodiments are only several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
