[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.

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

[0023] This invention provides a high-voltage vacuum circuit breaker with a waterproof structure.

[0024] In this embodiment, refer to Figure 1-5 This high-voltage vacuum circuit breaker with a waterproof structure 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, an installation box 5 above the vacuum circuit breaker 2, four support columns 4 fixedly connected inside the installation box 5, the support columns 4 penetrating the installation box 5, and four shielding components inside the installation box 5. Each shielding component includes two first upright plates 9 fixedly connected to the outside of the support columns 4, a first rotating rod 7 rotatably connected between the two first upright plates 9, and two first gears 8 fixedly connected to the outside of the first rotating rod 7. A first bevel gear 6 is fixedly connected to the outside of the first gear 8. A second gear 10 meshes with the outside of the first gear 8. A second rotating rod 12 is fixedly connected inside the second gear 10. A second upright plate 11 is rotatably connected to both ends of the second rotating rod 12. The outside of the second upright plate 11 is fixedly connected to the outside of the support column 4. A rainproof cloth roll 13 is fixedly connected to the outside of the second rotating rod 12. A rainproof cloth 14 is fixedly connected to the outside of the rainproof cloth roll 13. The rainproof cloth 14 passes through the mounting box 5 and is slidably connected. A limit rod 15 is slidably connected to the outside of the rainproof cloth 14. The two ends of the limit rod 15 are fixedly connected to the outside of two of the support columns 4 respectively.

[0025] The rotation of the first bevel gear 6 drives the first rotating rod 7 to rotate, which in turn drives the first gear 8 to rotate, which in turn drives the second gear 10 to rotate, which in turn drives the second rotating rod 12 to rotate, which in turn drives the rainproof cloth roll 13 to rotate, allowing the rainproof cloth 14 to descend and cover the vacuum circuit breaker 2. This prevents rainwater from getting on the vacuum circuit breaker 2 even when it is raining or windy, thus ensuring the safe operation of the vacuum circuit breaker 2. Furthermore, the rainproof cloth 14 can be retracted, allowing the vacuum circuit breaker 2 to dissipate heat when it is not raining, thus ensuring the heat dissipation capacity of the vacuum circuit breaker 2 and further ensuring its safety.

[0026] The installation box 5 is equipped with a transmission assembly, which includes a motor 16 fixedly connected to the bottom of the inner cavity of the installation box 5. A transmission rod 17 is fixedly connected to the transmission end of the motor 16. The top of the transmission rod 17 is rotatably connected to the top of the inner cavity of the installation box 5. An active bevel gear 18 is fixedly connected to the outside of the transmission rod 17.

[0027] The transmission assembly also includes four second bevel gears 19 meshing with the outside of the drive bevel gear 18. A third rotating rod 20 is fixedly connected to the outside of the second bevel gears 19. Two stabilizing blocks 21 are rotatably connected to the outside of the third rotating rod 20. The top of the stabilizing blocks 21 is fixedly connected to the top of the inner cavity of the mounting box 5. A third bevel gear 22 is fixedly connected to the end of the third rotating rod 20. The outside of the third bevel gear 22 meshes with the outside of the first bevel gear 6.

[0028] The motor 16 drives the transmission rod 17 to rotate, which in turn drives the drive bevel gear 18 to rotate, which in turn drives the second bevel gear 19 to rotate, which in turn drives the third rotating rod 20 to rotate, which in turn drives the third bevel gear 22 to rotate, which in turn drives the first bevel gear 6 to rotate.

[0029] The bottom of the rainproof cloth 14 is provided with an insertion component, which includes an insertion block 23 fixedly connected to the bottom of the rainproof cloth 14. Rollers 24 are rotatably connected to both ends of the insertion block 23. The rollers 24 pass through the support column 4 and are rotatably connected to the inside of the support column 4. A rainproof plate 25 is fixedly connected to the outside of the insertion block 23.

[0030] The movement of the rain cover 14 causes the insert block 23 to move, which in turn causes the roller 24 to rotate inside the support column 4, thereby causing the rain cover 25 to move.

[0031] The support column 4 is provided with an auxiliary component at its bottom. The auxiliary component includes a base plate 26 fixedly connected to the bottom of the support column 4. The top of the base plate 26 is fixedly connected to the bottom of the base 1. An insertion slot 27 is provided inside the base plate 26.

[0032] By moving the insert 23, which is relatively heavy, the insert 23 is moved into the insertion slot 27, thereby restricting the position of the rain cover 14.

[0033] The auxiliary components also include a fitting groove 28 inside the base plate 26, which is connected to the insertion groove 27. A drainage hole 29 is provided inside the base plate 26, which is connected to the insertion groove 27.

[0034] The insert 23 enters the insertion slot 27, thereby driving the rain shield 25 into the fitting slot 28, which in turn seals the groove on the bottom plate 26 and the space between the four support columns 4, thus preventing rainwater from entering the interior.

[0035] The top of the mounting box 5 is equipped with a measuring component, which includes a raindrop sensor 30 fixedly connected to the top of the mounting box 5, an anemometer 31 fixedly connected to the top of the raindrop sensor 30, and the raindrop sensor 30 and the anemometer 31 are electrically connected to the intelligent control device 3 respectively.

[0036] Raindrop sensor 30 detects rainwater to determine if it is raining, and wind speed is detected by an anemometer 31. When it rains and there is wind, the raindrop sensor 30 and the anemometer 31 transmit information to the intelligent control device 3 to control the motor 16, thereby controlling the winding and unwinding of the rainproof cloth 14.

[0037] The outer side of the insert block 23 is slidably connected to the inside of the insertion groove 27, and the outer side of the rain shield 25 is slidably connected to the inside of the fitting groove 28.

[0038] By sliding the insertion block 23 and the insertion slot 27 together, and by sliding the rain shield 25 and the fitting slot 28 together, the space inside the four support columns 4 can be sealed off, thus preventing rainwater from entering the space and ensuring the safety of the vacuum circuit breaker 2.

[0039] Working principle: The motor 16 drives the transmission rod 17 to rotate, which in turn drives the active bevel gear 18 to rotate, which in turn drives the second bevel gear 19 to rotate, which in turn drives the third rotating rod 20 to rotate, which in turn drives the third bevel gear 22 to rotate, which in turn drives the first bevel gear 6 to rotate, which in turn drives the first rotating rod 7 to rotate, which in turn drives the first gear 8 to rotate, which in turn drives the second gear 10 to rotate, which in turn drives the second rotating rod 12 to rotate, which in turn drives the rainproof cloth roll 13 to rotate, which allows the rainproof cloth 14 to descend and cover the vacuum circuit breaker 2. This prevents rainwater from getting on the vacuum circuit breaker 2 even when it is raining and windy, thus ensuring the safe operation of the vacuum circuit breaker 2. The rainproof cloth 14 can also be retracted, which allows the vacuum circuit breaker 2 to dissipate heat when it is not raining, thus ensuring the heat dissipation capacity of the vacuum circuit breaker 2 and further ensuring the safety of the vacuum circuit breaker 2.
