Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and in particular to an anti-static shell structure for a charging cabinet for mining equipment. Background Technology

[0002] Several problems urgently need to be addressed in the existing technology of charging cabinets for mining equipment. First, due to the complex mining environment, charging cabinets are often exposed to humid and dusty conditions, making the anti-static performance of the equipment a major challenge. Traditional charging cabinet casings often lack effective electrostatic protection measures, leading to static electricity accumulation and potentially causing equipment malfunctions or safety accidents. Furthermore, insufficient sealing performance allows dust and moisture to easily penetrate the interior of the charging cabinet, further accelerating the aging and damage of the equipment.

[0003] Secondly, convenience and stability are also crucial considerations during the installation and maintenance of charging cabinets for mining equipment. Traditional charging cabinets have complex outer shell structures and cumbersome installation procedures, which not only increase installation costs and time but also reduce work efficiency. Furthermore, the connection between the outer shell and internal components is often not secure enough, making them prone to loosening or detachment due to vibration or external forces, thus affecting the normal operation of the equipment. Therefore, we provide an anti-static outer shell structure for charging cabinets used in mining equipment. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an anti-static shell structure for a charging cabinet for mining equipment, which more accurately solves the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] The utility model proposes an anti-static shell structure for a charging cabinet for mining equipment, including a first shell and a second shell spliced ​​on both sides of the first shell. The first and second shells are characterized by having an n-shaped metal conductive frame slidingly attached to their outer periphery. A fixing plate is fixedly connected to the upper surface of the first shell. A plug-in plate is fixedly connected to the surface of the n-shaped metal conductive frame relative to the fixing plate. A plug-in slot for inserting the plug-in plate is transversely opened on the fixing plate. A limit mechanism is connected between the fixing plate and the plug-in plate.

[0007] The limiting mechanism includes a rectangular through groove two formed on the end wall of the insertion slot and a rectangular through groove one formed on the end of the insertion plate. The inner side wall of the rectangular through groove two is provided with a strip-shaped placement groove. A movable sleeve block is slidably connected to the inner wall of the strip-shaped placement groove. An arc-shaped limiting plate inserted into the inner wall of the rectangular through groove one is fixedly connected between the two movable sleeve blocks. A pulling rod is fixedly connected to one end of the arc-shaped limiting plate, and the pulling rod is located inside the rectangular through groove two. A reset component is connected between the strip-shaped placement groove and the movable sleeve block.

[0008] Furthermore, a sealing assembly is connected between the first outer casing and the second outer casing;

[0009] The sealing assembly includes a sealing slot formed on the surface of the first outer shell opposite to the second outer shell and a sealing insertion frame fixedly connected to the surface of the second outer shell opposite to the first outer shell. The sealing insertion frame is inserted into the inner wall of the sealing slot, and the two are in an interference fit.

[0010] Furthermore, the resetting component includes a horizontal fixing rod fixedly connected between the two end walls of the strip-shaped mounting groove, a spring sleeved around the horizontal fixing rod, and the movable sleeve block slidably sleeved around the horizontal fixing rod.

[0011] Furthermore, an L-shaped conductive plate is fixedly connected to one side surface of the n-shaped metal conductive frame. A through hole is opened on the upper surface of the L-shaped conductive plate. A ground contact guide rod is inserted into the inner wall of the through hole. An arc-shaped guide groove is vertically opened on the periphery of the ground contact guide rod. A metal guide rod is vertically fixedly connected to the inner wall of the through hole, and the metal guide rod is slidably connected to the inner wall of the arc-shaped guide groove.

[0012] Furthermore, one side of the arc-shaped limiting plate is designed in an arc shape, which is used to push the arc-shaped limiting plate into the interior of the rectangular through slot during the insertion of the plug plate into the plug slot.

[0013] Furthermore, one end of the spring is fixedly connected to the end wall of the strip-shaped mounting groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the outer shell 1 and outer shell 2 are designed to be joined together, which not only facilitates assembly and disassembly but also reduces the difficulty of transportation and storage. Simultaneously, the snap-fit ​​connection between the n-type metal conductive frame and the outer shell makes the installation of the conductive frame simpler and faster, eliminating the need for complex fixing steps. Furthermore, the design of the limiting mechanism greatly improves the stability between the plug-in plate and the fixing plate. Through the cooperation of the arc-shaped limiting plate and the reset component, the plug-in plate is automatically limited and stabilized, preventing loosening or detachment due to vibration or external force. This design not only improves the overall stability of the charging cabinet but also extends the service life of the equipment.

[0016] This invention effectively improves the anti-static performance of the charging cabinet by integrating conductive components such as an n-shaped metal conductive frame and an L-shaped conductive plate. The n-shaped metal conductive frame surrounds the outer shell and the outer shell, providing comprehensive electrostatic protection for the entire cabinet and ensuring that the internal equipment of the charging cabinet is protected from electrostatic interference and damage. At the same time, the design of the L-shaped conductive plate in conjunction with the grounding rod enables the charging cabinet to safely and reliably conduct static charge to the ground, further enhancing the anti-static effect.

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0024] Example

[0025] like Figure 1-Figure 5As shown in the figure, an embodiment of this utility model proposes an anti-static shell structure for a charging cabinet for mining equipment. The structure mainly includes a shell body 1, a shell body 2, an n-shaped metal conductive frame 3, a fixing plate 4, a plug-in plate 5, and a limiting mechanism. First, the shell body 1 serves as the main structure, and its two sides are connected to the shell body 2 through a specific splicing method to form a complete cabinet structure. This splicing design not only facilitates assembly and disassembly but also helps improve the flexibility and maintainability of the entire charging cabinet. An n-shaped metal conductive frame 3 is slidably attached to the periphery of the spliced ​​shell body 1 and shell body 2. The design of the n-shaped metal conductive frame 3 not only enhances the anti-static performance of the shell but also effectively guides the release of static charge, protecting the internal equipment of the charging cabinet from electrostatic interference and damage. A fixing plate 4 is fixedly connected to the upper surface of the shell body 1, serving as a support and fixing point for the plug-in plate 5. The n-type metal conductive frame 3 is fixedly connected to the surface of the fixed plate 4 with a plug plate 5. Through the plug-in cooperation between the plug plate 5 and the fixed plate 4, a stable connection between the n-type metal conductive frame 3 and the outer shell 1 is achieved.

[0026] In order to achieve the limiting and stabilizing of the plug-in plate 5 and the fixed plate 4, a limiting mechanism is also designed in this embodiment. Specifically, a plug-in groove 7 is horizontally through-holeed on the fixed plate 4 for the insertion of the plug-in plate 5. At the same time, a rectangular through groove 2 8 is formed on the end wall of the plug-in groove 7, and a rectangular through groove 1 6 is correspondingly formed at the end of the plug-in plate 5. The core components of the limiting mechanism include a strip-shaped placement groove 9 set on the inner side wall of the rectangular through groove 2 8, a movable sleeve block 12 slidably connected to the inner wall of the strip-shaped placement groove 9, and an arc-shaped limiting plate 13 fixedly connected between the two movable sleeve blocks 12. One end of the arc-shaped limiting plate 13 is fixedly connected to a lever 14, which is located inside the rectangular through slot 8, allowing the user to move the arc-shaped limiting plate 13 by lever 14. When the plug-in plate 5 is fully inserted into the plug-in slot 7, the user can pull the lever 14 outward to slide the arc-shaped limiting plate 13 in the strip-shaped placement slot 9 and insert it into the inner wall of the rectangular through slot 6, thereby achieving the limiting and stabilization between the plug-in plate 5 and the fixed plate 4. To ensure that the arc-shaped limiting plate 13 can automatically reset, a reset component such as a spring is also connected between the strip-shaped placement slot 9 and the moving sleeve 12. When the lever 14 is released, the reset component can push the moving sleeve 12 and the arc-shaped limiting plate 13 to automatically reset to the initial position.

[0027] Furthermore, the outer casing 1 and the outer casing 2 are tightly connected by a sealing assembly to prevent external factors such as dust and moisture from entering the charging cabinet. The sealing assembly includes a sealing slot 15 formed on the surface of the outer casing 1 opposite to the outer casing 2 and a sealing insertion frame 16 fixedly connected to the surface of the outer casing 2 opposite to the outer casing 1. The sealing insertion frame 16 is designed to be precisely inserted into the inner wall of the sealing slot 15, and the fit between the two is interference fit to ensure the airtightness between the outer casings. This interference fit design effectively prevents the intrusion of external substances such as water and dust, protecting the normal operation of the equipment inside the charging cabinet.

[0028] Furthermore, the reset component mainly includes a horizontal fixing rod 10 fixedly connected between the two end walls of the strip-shaped mounting groove 9. The horizontal fixing rod 10 serves as a support and guide structure, allowing the movable sleeve block 12 to slide around it. A spring 11 is sleeved around the horizontal fixing rod 10. One end of the spring 11 is fixedly connected to the end wall of the strip-shaped mounting groove 9, and the other end is fixedly connected to one end surface of the movable sleeve block 12. When the arc-shaped limiting plate 13 is moved by an external force, the spring 11 is compressed; when the external force disappears, the spring 11 uses its reset force to push the movable sleeve block 12 and the arc-shaped limiting plate 13 to automatically reset to their initial positions. This design not only ensures the reliability of the limiting mechanism but also improves the stability of the entire charging cabinet shell structure.

[0029] Furthermore, an L-shaped conductive plate 17 is fixedly connected to one side surface of the n-shaped metal conductive frame 3, and a through hole is formed on the upper surface of the L-shaped conductive plate 17. A ground contact guide rod 18 is inserted into the inner wall of the through hole. The ground contact guide rod 18 serves as a component connecting the n-shaped metal conductive frame 3 to the ground and can effectively conduct static charge into the ground. An arc-shaped guide groove 19 is vertically formed on the periphery of the ground contact guide rod 18, and a metal guide rod 20 is vertically fixedly connected to the inner wall of the through hole. The metal guide rod 20 slides within the inner wall of the arc-shaped guide groove 19. This design not only ensures a stable connection between the ground contact guide rod 18 and the L-shaped conductive plate 17, but also allows the ground contact guide rod 18 to be adjusted within a certain range to adapt to different ground conditions.
