Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, specifically to a pole-mounted circuit breaker with an anti-corrosion structure. Background Technology

[0002] With the rapid development of my country's economy and the continuous increase in power supply, especially the increasing dependence of various customers on electricity, in order to improve the power supply reliability of the power grid, pole-mounted circuit breakers are often used in the interconnection, segmentation and branch lines of the power grid to improve the power supply reliability of the power grid. Pole-mounted circuit breakers refer to circuit breakers installed and operated on poles. The research level and manufacturing technology of various circuit breakers have made great progress.

[0003] According to a public disclosure of a pole-mounted circuit breaker with an anti-corrosion mechanism (publication number: CN 218385060U): it includes a pole-mounted circuit breaker body, a base placed at the bottom of the pole-mounted circuit breaker body, an insulating layer sleeve fixedly connected to the top of the pole-mounted circuit breaker body, a connecting end fixedly connected to the top of the insulating layer sleeve, a limiting ring engaged in the gap at the top of the insulating layer sleeve on the left side, a connecting post fixedly connected to the top of the limiting ring, a wall cover fixedly connected to the other end of the connecting post, and the wall cover engaged with the connecting end, and an anti-corrosion shell fixedly connected to the rear end of the wall cover.

[0004] In the aforementioned application, the cooperation between the circuit breaker body and the enclosure assembly makes it difficult to lock the circuit breaker body during use, resulting in unstable installation of the circuit breaker body. This can cause the circuit breaker body to shake or fall due to external forces during operation. Therefore, we propose a pole-mounted circuit breaker with a corrosion-resistant structure. Utility Model Content

[0005] This utility model proposes a pole-mounted circuit breaker with a corrosion-resistant structure, which solves the problem of unstable installation of circuit breakers in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model is a pole-mounted circuit breaker with a corrosion-resistant structure, including a circuit breaker body, a connecting end provided at the top of the circuit breaker body, a mounting rod provided at the bottom of the circuit breaker body, and an installation mechanism provided inside the circuit breaker body.

[0008] The mounting mechanism includes a threaded rod, the circumferential surface of which penetrates the side of the circuit breaker body and is rotatably connected to the side of the circuit breaker body. A threaded sleeve is threaded onto the circumferential surface of the threaded rod, and a push rod is fixedly connected to the bottom of the threaded sleeve. A hydraulic cylinder is fixedly connected to the bottom of the circuit breaker body. One end of the hydraulic cylinder is slidably connected to a force-bearing rod via a piston, and the other end of the hydraulic cylinder is slidably connected to a hydraulic rod via another piston. A mounting hole is provided on the side of the mounting rod.

[0009] Optionally, a spring hole is provided on the circumferential surface of the hydraulic rod, and a compression spring is fixedly connected inside the spring hole. A locking post is fixedly connected to the end of the compression spring away from the inside of the spring hole. The function of the locking post is to stably fix the circuit breaker body to the mounting rod.

[0010] Optionally, one end of the locking pin is elastically connected to the inside of the spring hole via a compression spring, and one end of the threaded rod is fixedly connected to a turning handle. The circumferential surface of the threaded rod is fixedly penetrated by a limiting plate. The function of the turning handle is to facilitate the operator to rotate the threaded rod, and the function of the limiting plate is to limit the displacement distance of the threaded sleeve.

[0011] Optionally, one end of the force-bearing rod is located on the displacement trajectory of the push rod. The number of spring holes, compression springs, and locking pins is set to two, and they are symmetrical to each other along the vertical central axis of the hydraulic cylinder. The function of one end of the force-bearing rod being located on the displacement trajectory of the push rod is to ensure that the push rod can press the force-bearing rod when it moves. The circuit breaker body is doubly stabilized and fixed by the two locking pins to improve stability.

[0012] Optionally, a coating mechanism is provided on the top of the circuit breaker body. The coating mechanism includes a connecting rod, one end of which is fixedly connected to the top of a threaded sleeve. A double-sided rack is fixedly connected to the end of the connecting rod away from the top of the threaded sleeve. A control shaft passes through the top of the circuit breaker body and is rotatably connected to the circumferential surface of the control shaft. A gear is fixedly passed through the circumferential surface of the control shaft. A first conveying tank is fixedly connected to the circumferential surface of the control shaft. A first coating brush is fixedly connected to the circumferential surface of the first conveying tank. A first liquid storage tank is fixedly connected to the top of the first conveying tank. The function of providing a coating mechanism on the top of the circuit breaker body is to coat the outside of the connecting end, isolate moisture and air, and prevent corrosion.

[0013] Optionally, a chain is provided on the circumferential surface of the control shaft, and a support shaft is rotatably connected to the top of the circuit breaker body. The circumferential surface of the control shaft is connected to the circumferential surface of the support shaft through the chain. The function of the chain is to drive the support shaft to rotate through the control shaft.

[0014] Optionally, a second conveying barrel is fixedly connected to the circumferential surface of the support shaft, a second coating brush is fixedly connected to the circumferential surface of the second conveying barrel, and a second liquid storage tank is fixedly connected to the top of the second conveying barrel. The function of the second coating brush is to ensure that each connection end can be coated.

[0015] Optionally, the side surface of the double-sided rack meshes with the circumferential surface of the gear. The number of the gear, the first coated brush, and the chain is set to two, and they are symmetrical about each other along the numerical central axis of the circuit breaker body. The function of the side surface of the double-sided rack meshing with the circumferential surface of the gear is to ensure that the movement of the double-sided rack can drive the gear to rotate.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] In this invention, through the cooperation of components such as the threaded rod, hydraulic cylinder, and locking column of the installation mechanism, when the circuit breaker body needs to be installed, the circuit breaker body is first simply installed on the installation rod. Then, the operator turns the handle, causing the push rod to move and press the force rod. At this time, the hydraulic rod moves through the installation hole to fix the circuit breaker body. Simultaneously, the locking column is forced into the spring hole and passes through the installation hole. Then, the locking column is released by the elasticity of the compression spring, locking the circuit breaker body. This design achieves the effect of stable installation of the circuit breaker, effectively improving the stability of the circuit breaker on the pole and enhancing safety.

[0018] In this invention, the double-sided rack, gear, and second coating brush of the coating mechanism work together to move the threaded sleeve from right to left, while the connecting rod drives the double-sided rack to move from right to left. The meshing of the double-sided rack and gear causes the control shaft to rotate. The liquid inside the first storage tank enters the first coating brush through the first conveying bucket, causing the first conveying bucket to rotate and drive the first coating brush to coat the connection end surface of the circuit breaker body with epoxy resin. This gives the connection end surface an anti-corrosion coating. This design achieves the effect of coating the connection end of the circuit breaker, effectively isolating moisture and air, preventing corrosion, and improving service life.

[0030] Reference Figures 1-5 This is the first embodiment of the present utility model, which proposes a pole-mounted circuit breaker with a corrosion-resistant structure, including a circuit breaker body 1, a connecting end 2 provided on the top of the circuit breaker body 1, an mounting rod 3 provided on the bottom of the circuit breaker body 1, and an installation mechanism 4 provided inside the circuit breaker body 1.

[0031] The mounting mechanism 4 includes a threaded rod 41, the circumferential surface of which penetrates the side of the circuit breaker body 1 and is rotatably connected to the side of the circuit breaker body 1. A threaded sleeve 42 is threadedly connected to the circumferential surface of the threaded rod 41. A push rod 43 is fixedly connected to the bottom of the threaded sleeve 42. A hydraulic cylinder 44 is fixedly connected to the bottom of the circuit breaker body 1. One end of the hydraulic cylinder 44 is slidably connected to a force-bearing rod 45 via a piston. The other end of the hydraulic cylinder 44 is slidably connected to a hydraulic rod 46 via another piston. A mounting hole 47 is provided on the side of the mounting rod 3.

[0032] A spring hole 48 is provided on the circumferential surface of the hydraulic rod 46. A compression spring 49 is fixedly connected inside the spring hole 48. A locking pin 410 is fixedly connected to one end of the compression spring 49 away from the inside of the spring hole 48. The function of the locking pin 410 is to stably fix the circuit breaker body 1 to the mounting rod 3.

[0033] One end of the locking pin 410 is elastically connected to the inside of the spring hole 48 via a compression spring 49. One end of the threaded rod 41 is fixedly connected to a turning handle 411. The circumferential surface of the threaded rod 41 is fixedly penetrated by a limit plate 412. The function of the turning handle 411 is to facilitate the operator to rotate the threaded rod 41. The function of the limit plate 412 is to limit the displacement distance of the threaded sleeve 42.

[0034] One end of the force-bearing rod 45 is located on the displacement trajectory of the push rod 43. Two spring holes 48, compression springs 49, and locking pins 410 are provided, symmetrically arranged along the vertical central axis of the hydraulic cylinder 44. The purpose of having one end of the force-bearing rod 45 on the displacement trajectory of the push rod 43 is to ensure that the movement of the push rod 43 can press the force-bearing rod 45. The two locking pins 410 provide double stabilization and fixation to the circuit breaker body 1, improving stability.

[0035] In this embodiment, when the circuit breaker body 1 needs to be installed, the circuit breaker body 1 is first simply installed on the mounting rod 3. Then, the operator turns the handle 411, causing the threaded rod 41 to rotate counterclockwise. The rotation of the threaded rod 41 drives the threaded sleeve 42 to move from right to left. The movement of the threaded sleeve 42 drives the push rod 43 to move from right to left. During the movement of the push rod 43, it presses the force rod 45. The force rod 45 is forced to retract into the hydraulic cylinder 44. At this time, the hydraulic rod 46 is pushed outward by the pressure of the liquid inside the hydraulic cylinder 44. The hydraulic rod 46 moves through the mounting hole 47 to fix the circuit breaker body 1. At the same time, the locking pin 410 is forced into the spring hole 48 and passes through the mounting hole 47. At this time, the locking pin 410 is popped out by the elasticity of the compression spring 49 to lock the circuit breaker body 1. Example 2

[0036] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a coating mechanism 5 is provided on the top of the circuit breaker body 1. The coating mechanism 5 includes a connecting rod 51, one end of which is fixedly connected to the top of the threaded sleeve 42, and the other end of which, away from the top of the threaded sleeve 42, is fixedly connected to a double-sided rack 52. A control shaft 53 passes through the top of the circuit breaker body 1 and is rotatably connected to the circumferential surface of the control shaft 53. A gear 54 is fixedly passed through the circumferential surface of the control shaft 53. A first conveying tank 55 is fixedly connected to the circumferential surface of the control shaft 53. A first coating brush 56 is fixedly connected to the circumferential surface of the first conveying tank 55. A first liquid storage tank 57 is fixedly connected to the top of the first conveying tank 55. The function of the coating mechanism 5 on the top of the circuit breaker body 1 is to coat the outside of the connecting end 2, isolating it from moisture and air, and preventing corrosion.

[0037] A chain 58 is provided on the circumferential surface of the control shaft 53, and a support shaft 59 is rotatably connected to the top of the circuit breaker body 1. The circumferential surface of the control shaft 53 is connected to the circumferential surface of the support shaft 59 through the chain 58. The function of the chain 58 is to drive the support shaft 59 to rotate through the control shaft 53.

[0038] A second conveying tank 510 is fixedly connected to the circumferential surface of the support shaft 59. A second coating brush 511 is fixedly connected to the circumferential surface of the second conveying tank 510. A second liquid storage tank 512 is fixedly connected to the top of the second conveying tank 510. The function of the second coating brush 511 is to ensure that each connection end 2 can be coated.

[0039] The side surface of the double-sided rack 52 meshes with the circumferential surface of the gear 54. Two gears 54, two first-coated brushes 56, and two chains 58 are provided, symmetrically arranged along the numerical axis of the circuit breaker body 1. The meshing of the side surface of the double-sided rack 52 with the circumferential surface of the gear 54 ensures that the movement of the double-sided rack 52 can drive the gear 54 to rotate.

[0040] Compared to Embodiment 1, further, while the threaded sleeve 42 moves from right to left, the connecting rod 51 drives the double-sided rack 52 to move from right to left. The double-sided rack 52 meshes with the gear 54, causing the double-sided rack 52 to move and drive the gear 54 to rotate. The rotation of the gear 54 drives the first conveying tank 55 to rotate via the control shaft 53. At this time, the liquid inside the first storage tank 57 enters the first coating brush 56 through the first conveying tank 55, causing the first conveying tank 55 to rotate and drive the first coating brush 56 to coat the surface of the connecting end 2 of the circuit breaker body 1 with epoxy resin, so that the surface of the connecting end 2 has a coating with anti-corrosion properties. At the same time, the control shaft 53 drives the support shaft 59 to rotate via the chain 58, so that the liquid inside the second storage tank 512 enters the second coating brush 511 through the second conveying tank 510, so that the second coating brush 511 coats the other connecting ends 2.
