Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker technology, specifically a high-voltage vacuum circuit breaker that is easy to install. Background Technology

[0002] A vacuum circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. Vacuum circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When they experience serious overload, short circuit, or undervoltage faults, they can automatically disconnect the circuit. Their function is equivalent to a combination of a fuse switch and an over / under-temperature relay.

[0003] Vacuum circuit breakers used today are installed in both outdoor and indoor locations. When installed outdoors, they are typically lifted by a crane or forklift before installation. However, for indoor installations, cranes and forklifts are often unavailable, requiring manual handling. The weight of vacuum circuit breakers makes handling inconvenient, and any shaking during handling can damage the circuit breaker and potentially injure the personnel handling it.

If the specific posture changes, the directional indicators will also change accordingly.

[0023] This invention provides a high-voltage vacuum circuit breaker that is easy to install.

[0024] In this embodiment, refer to Figure 1-5 This easy-to-install high-voltage vacuum circuit breaker includes a base 1, a vacuum circuit breaker 2 fixedly connected to the top of the base 1, an intelligent control device 3 fixedly connected to the outside of the base 1, and a mounting frame 4 fixedly connected to the bottom of the base 1. A moving assembly is provided inside the mounting frame 4, comprising two first rotating rods 5 rotatably connected inside the mounting frame 4. A mounting block 6 is fixedly connected to the outside of the first rotating rods 5, and a caster wheel 7 is fixedly connected to the end of the mounting block 6. A connecting block 8 is rotatably connected inside the mounting block 6, and a storage block 10 is slidably connected to the outside of the connecting block 8. A second rotating rod 9 is rotatably connected inside the connecting block 8, with both ends of the second rotating rod 9 fixedly connected to the inside of the mounting frame 4. A third rotating rod 11 is rotatably connected inside the storage block 10.

[0025] The movement of the third rotating rod 11 moves the storage block 10, causing the connecting block 8 to slide inside the storage block 10. This causes the connecting block 8 to rotate along the second rotating rod 9, which in turn causes the mounting block 6 to rotate along the first rotating rod 5. This causes the caster 7 to move, making it contact the ground and support the mounting frame 4, thus supporting the vacuum circuit breaker 2. The caster 7 also assists in moving the vacuum circuit breaker 2, making it easier to move the vacuum circuit breaker 2 indoors and thus facilitating its installation indoors, reducing the difficulty of transporting the vacuum circuit breaker 2.

[0026] The mounting frame 4 is equipped with a transmission assembly, which includes a mounting plate 12 fixedly connected to the inside of the mounting frame 4. A motor 13 is fixedly connected to the top of the mounting plate 12, and a first reciprocating screw 14 is fixedly connected to the transmission end of the motor 13. There are two first reciprocating screws 14.

[0027] The transmission assembly also includes a first one-way bearing 15 rotatably connected between two first reciprocating screws 14, and a transmission block 16 is threadedly connected to the outer side of the first reciprocating screws 14.

[0028] The motor 13 drives the first reciprocating screw 14 to rotate forward, thereby transmitting power to the second reciprocating screw 14 through the first one-way bearing 15, which in turn drives the transmission block 16 to rise and fall, and in turn drives the third rotating rod 11 to move.

[0029] The first reciprocating screw 14 is provided with a lifting assembly on its outer side. The lifting assembly includes a first gear 17 fixedly connected to the outer side of the first reciprocating screw 14. Four second gears 18 are meshed on the outer side of the first gear 17. A transmission rod 19 is fixedly connected inside the second gear 18. The top of the transmission rod 19 is rotatably connected to the top of the inner cavity of the mounting frame 4.

[0030] The lifting assembly also includes a second one-way bearing 20 rotatably connected to the bottom of the transmission rod 19. A second reciprocating screw 21 is rotatably connected to the bottom of the second one-way bearing 20. A screw cylinder 22 is threadedly connected to the outer side of the second reciprocating screw 21. A support block 23 is fixedly connected to the bottom of the screw cylinder 22.

[0031] The reversal of the first reciprocating screw 14 drives the first gear 17 to rotate, which in turn drives the second gear 18 to rotate, which in turn drives the transmission rod 19 to rotate. This, in turn, drives the second reciprocating screw 21 to rotate via the second one-way bearing 20, which in turn drives the screw barrel 22 to move, which in turn drives the support block 23 to move. This supports the vacuum circuit breaker 2, thereby lifting the vacuum circuit breaker 2 and facilitating the movement of the caster wheel 7, which in turn supports the vacuum circuit breaker 2, making it easier to transport the vacuum circuit breaker 2 in the future.

[0032] The transmission block 16 is rotatably connected to the outer sides of the two third rotating rods 11.

[0033] The movement of the transmission block 16 drives the movement of the third rotating rod 11.

[0034] Among them, the intelligent control device 3 is electrically connected to the vacuum circuit breaker 2, and the intelligent control device 3 is electrically connected to the motor 13.

[0035] The vacuum circuit breaker 2 and the motor 13 are controlled by the intelligent control device 3 to ensure the normal operation of the device.

[0036] Among them, the mounting block 6 passes through the mounting frame 4 and is slidably connected, and the universal wheel 7 passes through the mounting frame 4 and is slidably connected.

[0037] By moving the mounting block 6, the mounting block 6 can drive the caster 7 to move, thereby facilitating the support of the vacuum circuit breaker 2 by the caster 7.

[0038] Working principle: The motor 13 drives the first reciprocating screw 14 to rotate forward, thereby transmitting power to the second reciprocating screw 14 through the first one-way bearing 15. This drives the transmission block 16 to rise and fall, which in turn drives the third rotating rod 11 to move, thereby driving the storage block 10 to move. This causes the connecting block 8 to slide inside the storage block 10, and then the connecting block 8 rotates along the second rotating rod 9. This causes the mounting block 6 to rotate along the first rotating rod 5, thereby moving the caster 7. The caster 7 then comes into contact with the ground and supports the mounting frame 4, thus supporting the vacuum circuit breaker 2. The caster 7 also assists in moving the vacuum circuit breaker 2, making it easier to move the vacuum circuit breaker 2 indoors, thus facilitating indoor installation and reducing the difficulty of transporting the vacuum circuit breaker 2.

[0039] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
