Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically to a surface treatment device for aluminum alloy housings of high-voltage circuit breakers. Background Technology

[0002] A high-voltage circuit breaker is a switching device used in power systems. Its main function is to connect or disconnect circuits under normal operating conditions and to quickly disconnect circuits in the event of a short circuit or other abnormal conditions, protecting the power system and electrical equipment from damage. The aluminum alloy casing of a high-voltage circuit breaker refers to the outer shell of the circuit breaker made of aluminum alloy. Aluminum alloy is widely used in the manufacture of high-voltage circuit breakers due to its ease of processing, good visual appearance, light weight, and excellent corrosion resistance. During the processing of the aluminum alloy casing of a high-voltage circuit breaker, surface treatment equipment is typically used to treat the surface of the aluminum alloy casing to improve its surface quality. Surface treatment equipment is a type of equipment used to treat the surfaces of materials such as metals, plastics, and ceramics, aiming to improve the surface properties of the materials. Common surface treatment methods include anodizing, electroplating, spraying, and polishing. Anodizing or electroplating can enhance the corrosion resistance of the casing, extend its service life, and significantly improve the durability of the aluminum alloy casing, reducing the frequency of maintenance and replacement.

[0003] In existing technologies, when surface treating aluminum alloy housings, the aluminum alloy housing is usually placed directly into an electrolytic cell or placed in a mesh frame, with the mesh frame immersed in the electrolyte. However, since aluminum alloy housings come in various sizes, the mesh frame cannot be flexibly adjusted to suit different housing sizes, resulting in poor processing flexibility. Therefore, to address these issues, a surface treatment device for high-voltage circuit breaker aluminum alloy housings is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] The first motor 22 and the second motor 33 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A surface treatment device for aluminum alloy shells of high-voltage circuit breakers includes a tank, which includes an electrolytic tank 1. An outlet pipe 11 is fixedly connected to the surface of the electrolytic tank 1. A support frame 12 is fixedly connected to the top of the electrolytic tank 1. A connecting plate 13 is provided at the bottom of the support frame 12. A mesh frame 14 is provided at the bottom of the connecting plate 13. The mesh frame 14 can support and place the aluminum alloy shell. By immersing the mesh frame 14 and the aluminum alloy shell in the electrolyte in the electrolytic tank 1 and energizing the electrolyte, metal ions can be reduced and deposited on the surface of the aluminum alloy shell, thereby forming a uniform coating, thus achieving surface treatment of the aluminum alloy shell.

[0024] A displacement mechanism is provided on the inner side of the connecting plate 13. The displacement mechanism includes a first fixed block 2, which is fixedly connected to the lower surface of the connecting plate 13. A positive and negative screw 21 is movably connected to the inner side of the first fixed block 2. A first motor 22 is fixedly installed on the surface of the first fixed block 2. A moving block 23 is threadedly connected to the surface of the positive and negative screw 21. The mesh frame 14 is fixedly connected to the bottom end of the moving block 23. By rotating the positive and negative screw 21, the moving block 23 can drive the mesh frame 14 to move, thereby enabling the adjustment of the mesh frame 14. This allows the mesh frame 14 to adapt to aluminum alloy shells of different sizes, facilitating better placement of the aluminum alloy shells and making the processing of the aluminum alloy shells more flexible.

[0025] Furthermore, the displacement mechanism also includes a limiting block 24, which is fixedly connected to the top of the moving block 23. A limiting groove 25 is provided on the inner side of the connecting plate 13. By setting the limiting block 24 and opening the limiting groove 25, the moving block 23 can be limited, which can prevent the moving block 23 from shifting under the action of the positive and negative screws 21, and facilitate the moving block 23 to drive the mesh frame 14 to move horizontally in a stable manner.

[0026] Furthermore, the positive and negative screws 21 are fixedly connected to the output end of the first motor 22, and the moving blocks 23 are movably connected to the positive and negative screws 21 in two groups. One end of the limiting block 24 is fixedly connected to the moving block 23, and the other end of the limiting block 24 is movably connected to the limiting groove 25. By rotating the positive and negative screws 21, the moving blocks 23 can be moved, thereby facilitating the adjustment of the position and spacing of the mesh frame 14.

[0027] Furthermore, a lifting mechanism is provided on the inner side of the support frame 12. The lifting mechanism includes a second fixed block 3, which is fixedly connected to the top of the support frame 12. A rotating rod 31 is movably connected to the inner side of the second fixed block 3. A first conical tooth 32 is fixedly connected to the surface of the rotating rod 31. A second motor 33 is fixedly installed on the surface of the second fixed block 3. A third fixed block 34 is fixedly connected to the inner surface of the support frame 12. A threaded rod 35 is movably connected to the inner side of the third fixed block 34. A second conical tooth 36 is fixedly connected to the top of the threaded rod 35. A connecting block 37 is threadedly connected to the surface of the threaded rod 35. By rotating the threaded rod 35, the connecting block 37 can drive the connecting plate 13 and the mesh frame 14 to move up and down, which facilitates the immersion of the aluminum alloy shell into the electrolytic cell 1 and the removal of the aluminum alloy shell, making the processing of the aluminum alloy shell more convenient.

[0028] Furthermore, the output ends of the rotating rod 31 and the second motor 33 are fixedly connected, and the threaded rod 35 is movably connected to the support frame 12 in two sets. By rotating the rotating rod 31, the first conical tooth 32 can be rotated, thereby enabling the first conical tooth 32 to transmit power to the second conical tooth 36, which facilitates the rotation of the threaded rod 35 and causes the connecting block 37 to drive the connecting plate 13 and the mesh frame 14 to move vertically.

[0029] Furthermore, the second conical teeth 36 are connected in two sets to the threaded rod 35, and the connecting blocks 37 are connected in two sets to the threaded rod 35. The connecting blocks 37 are fixedly connected to the connecting plate 13. By setting the connecting blocks 37, when the threaded rod 35 rotates, the connecting blocks 37 can move vertically, thereby enabling the connecting plate 13 to drive the mesh frame 14 to rise and fall, which facilitates the lowering or lifting of the aluminum alloy shell.

[0030] Working principle: In use, the first motor 22 is electrically connected to an external power source. The operator starts the first motor 22 by pressing the switch. The first motor 22 drives the positive and negative screws 21 to rotate. The moving block 23 is limited by the limiting block 24 and the limiting groove 25. It will move under the action of the positive and negative screws 21, so that the limiting block 24 can move inside the limiting groove 25. Then, the mesh frame 14 moves with the moving block 23, so that the mesh frame 14 can adapt to different sizes of aluminum alloy shells.

[0031] The second motor 33 is electrically connected to an external power source. The operator starts the second motor 33 by pressing a switch. The second motor 33 drives the rotating rod 31 to rotate. The first conical tooth 32 will rotate under the action of the rotating rod 31. The second conical tooth 36 will rotate under the action of the first conical tooth 32 and drive the threaded rod 35 to rotate. This enables the connecting block 37 to move on the surface of the threaded rod 35 and causes the connecting plate 13 to drive the mesh frame 14 to move vertically. This allows the aluminum alloy shell to be immersed in the electrolyte or to be easily removed.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
