Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to an outdoor vacuum circuit breaker. Background Technology

[0002] Outdoor vacuum circuit breakers are high-voltage switchgear used in outdoor environments. They are mainly used to break and close load currents, overload currents, and short-circuit currents in power lines, playing an important role in the control and protection of power systems.

[0003] The installation of existing outdoor vacuum circuit breakers often requires complex operating procedures and professional tools. The connection between the circuit breaker body and the base is mostly fixed with bolts or welded. Although these methods ensure the stability of the connection, they sacrifice the convenience of installation. When the circuit breaker needs to be maintained, replaced or upgraded, the disassembly process is also cumbersome, which is not only time-consuming and labor-intensive, but may also damage the equipment due to improper operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology of outdoor vacuum circuit breakers has the disadvantages of complicated installation, requiring professional tools, and connection methods such as bolts or welding. Although stable, they are inconvenient. During maintenance, replacement or upgrade, disassembly is cumbersome, time-consuming and labor-intensive, and the equipment is easily damaged. Therefore, we propose an outdoor vacuum circuit breaker.

[0005] To achieve the above objectives, this application adopts the following technical solution: an outdoor vacuum circuit breaker, including a base, an outdoor vacuum circuit breaker body installed on the top of the base, two plug-in slots opened on the top of the base, hollow blocks fixedly connected to both sides of the outdoor vacuum circuit breaker body, a baffle fixedly connected inside the hollow block, an adjusting rod slidably connected inside the baffle, an arc-shaped pushing block fixedly connected to one side of the adjusting rod, an arc-shaped force-bearing block abutting against the bottom of the arc-shaped pushing block, a plug-in rod fixedly connected to the bottom of the arc-shaped force-bearing block, and a through slot opened at the bottom of the hollow block.

[0006] Preferably, a reset spring is fixedly connected to the bottom of the arc-shaped force-bearing block, and the bottom of the reset spring is fixedly connected to the bottom of the inner cavity of the hollow block.

[0007] Preferably, the surface of the plug rod is slidably connected to the inside of the plug groove, and the external shape of the plug rod matches the internal shape of the plug groove.

[0008] Preferably, both ends of the hollow block's inner cavity are provided with sliding grooves, and both sides of the arc-shaped force-bearing block are fixedly connected with sliders.

[0009] Preferably, the base has two slots on its top, and the bottom of the outdoor vacuum circuit breaker body is fixedly connected to an extension block. The bottom of the extension block has a movable slot, and the internal shaft of the movable slot is rotatably connected to multiple rollers.

[0010] Preferably, the top of the base is provided with a convex limiting groove, and the bottom of the outdoor vacuum circuit breaker body is fixedly connected with a convex limiting block.

[0011] Preferably, a rain shield is fixedly connected to one end of the outdoor vacuum circuit breaker body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the adjusting rod outward, the arc-shaped pushing block releases its contact with the arc-shaped force-bearing block. At this time, the return force of the reset spring pushes the arc-shaped force-bearing block upward, and the arc-shaped force-bearing block drives the plug rod to move outward through the through slot, so that the plug rod disengages from the inside of the plug slot. This makes it easier for the staff to disassemble the outdoor vacuum circuit breaker body, and facilitates its inspection and replacement. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an outdoor vacuum circuit breaker, including a base 1, an outdoor vacuum circuit breaker body 2 mounted on the top of the base 1, two insertion slots 3 opened on the top of the base 1, hollow blocks 4 fixedly connected to both sides of the outdoor vacuum circuit breaker body 2, a baffle 5 fixedly connected inside the hollow block 4, an adjusting rod 6 slidably connected inside the baffle 5, an arc-shaped pushing block 7 fixedly connected to one side of the adjusting rod 6, an arc-shaped force-bearing block 8 abutting the bottom of the arc-shaped pushing block 7, an insertion rod 9 fixedly connected to the bottom of the arc-shaped force-bearing block 8, and a hole opening at the bottom of the hollow block 4. A return spring 20 is fixedly connected to the bottom of the arc-shaped force-bearing block 8 in the through slot 10. The bottom of the return spring 20 is fixedly connected to the bottom of the inner cavity of the hollow block 4. When the operator pulls the adjusting rod 6 outward, the arc-shaped pushing block 7 releases its contact with the arc-shaped force-bearing block 8. At this time, the rebound force of the return spring 20 pushes the arc-shaped force-bearing block 8 to move upward. The arc-shaped force-bearing block 8 drives the plug rod 9 to move outward through the through slot 10, so that the plug rod 9 is disengaged from the inside of the plug slot 3. This makes it easier for the operator to disassemble the outdoor vacuum circuit breaker body 2, and facilitates its inspection and replacement.

[0022] Reference Figure 2 and Figure 4 As shown in this embodiment: the surface of the plug rod 9 is slidably connected to the inside of the plug groove 3, and the external shape of the plug rod 9 matches the internal shape of the plug groove 3. Since the surface of the plug rod 9 is slidably connected to the inside of the plug groove 3, and the two external shapes match, this design brings many benefits. During the installation process, it can ensure that the plug rod 9 is accurately and smoothly inserted into the plug groove 3 to achieve a stable connection, so that the outdoor vacuum circuit breaker body 2 is stable and reliable after installation.

[0023] Reference Figure 4 As shown in this embodiment: both ends of the inner cavity of the hollow block 4 are provided with sliding grooves 11, and both sides of the arc-shaped force block 8 are fixedly connected with sliders 12. The cooperation between the sliders 12 and the sliding grooves 11 restricts the movement direction of the arc-shaped force block 8, so that it can only move up and down along a specific path under the push of the return spring 20, thus ensuring the accuracy and stability of the movement of the arc-shaped force block 8 and the plug rod 9.

[0024] Reference Figure 5As shown in this embodiment: the top of the base 1 has two slots 15, the bottom of the outdoor vacuum circuit breaker body 2 is fixedly connected to an extension block 16, the bottom of the extension block 16 has a movable slot 17, and the internal shaft of the movable slot 17 is rotatably connected to multiple rollers 18. The multiple rollers 18 rotatably connected to the movable slot 17 at the bottom of the extension block 16 through the rotating shaft not only play a good auxiliary sliding role when the outdoor vacuum circuit breaker body 2 is installed or disassembled, but also make it easier for workers to install.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: a convex limiting groove 13 is provided on the top of the base 1, and a convex limiting block 14 is fixedly connected to the bottom of the outdoor vacuum circuit breaker body 2. The cooperation between the convex limiting block 14 and the convex limiting groove 13 enables the outdoor vacuum circuit breaker body 2 to be stably limited on the base 1 after installation, effectively preventing it from shaking or displacing due to external forces during operation.

[0026] Reference Figure 3 As shown in this embodiment: a rain shield 19 is fixedly connected to one end of the outdoor vacuum circuit breaker body 2. The rain shield 19 effectively blocks the top of the convex limiting groove 13, so that rainwater cannot drip directly into the convex limiting groove 13.

[0027] Working principle: By pulling the adjusting rod 6 outward, the arc-shaped pushing block 7 releases its contact with the arc-shaped force-bearing block 8. At this time, the return force of the return spring 20 pushes the arc-shaped force-bearing block 8 upward. The arc-shaped force-bearing block 8 then drives the plug-in rod 9 outward through the through slot 10, disengaging the plug-in rod 9 from the inside of the plug-in slot 3. This facilitates disassembly of the outdoor vacuum circuit breaker body 2, making it easier for maintenance and replacement. Because the surface of the plug-in rod 9 slides smoothly into the inside of the plug-in slot 3, and their external shapes match, this design offers many benefits. During installation, it ensures that the plug-in rod 9 is accurately and smoothly inserted into the plug-in slot 3, achieving a stable connection. This ensures the outdoor vacuum circuit breaker body 2 is stable and reliable after installation. The cooperation between the slider 12 and the slide groove 11 restricts the arc... The direction of movement of the arc-shaped force block 8 ensures that it can only move up and down along a specific path under the push of the return spring 20, thus ensuring the accuracy and stability of the movement of the arc-shaped force block 8 and the plug rod 9. The multiple rollers 18 connected by the rotating shaft in the movable groove 17 at the bottom of the extension block 16 not only play a good auxiliary sliding role when installing or disassembling the outdoor vacuum circuit breaker body 2, making it easier for workers to install, but also the cooperation between the convex limiting block 14 and the convex limiting groove 13 ensures that the outdoor vacuum circuit breaker body 2 can be firmly limited on the base 1 after installation, effectively preventing it from shaking or displacing due to external forces during operation. The rain shield 19 effectively blocks the top of the convex limiting groove 13, preventing rainwater from dripping directly into the convex limiting groove 13.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
