Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and more specifically, to a high and low voltage power distribution cabinet. Background Technology

[0002] High-voltage and low-voltage switchgear are devices used to receive, distribute, and protect electrical energy. They are classified into high-voltage switchgear and low-voltage switchgear according to voltage level. They play a crucial role in the power system, ensuring the safe, stable, and efficient distribution of electrical energy.

[0003] A search revealed a Chinese patent application with patent number CN220341750U, which discloses a high and low voltage distribution cabinet, including a cabinet body. The top outer wall of the cabinet body has two exhaust ports, and the inner walls of the two exhaust ports are fixedly connected to exhaust pipes. The top outer walls of the two exhaust pipes are fixedly connected to exhaust boxes, the diameter of which is larger than that of the exhaust pipes, and the exhaust boxes and exhaust pipes are connected. The bottom outer wall of the exhaust box has three arc-shaped openings that are evenly distributed in a circular pattern, and the inner walls of the three arc-shaped openings are fixedly connected to dustproof nets. The inner wall of the exhaust pipes is fixedly connected to a fan, and the bottom outer wall of the exhaust pipes is fixedly connected to a protective net.

[0004] Although the aforementioned patent facilitates air exhaust from the distribution cabinet by using a combination of an exhaust pipe and an exhaust box at the top of the cabinet body, thus aiding in heat dissipation, and includes an arc-shaped exhaust port at the bottom of the exhaust box with a dustproof mesh on its inner wall to prevent clogging and eliminate the need for cleaning, and a sliding block within the exhaust box to close the arc-shaped port when the cabinet is not in operation, the following shortcomings still exist during use: 1. The device lacks a structure for drying humid air, making it prone to damage or degradation of internal equipment in humid weather. 1. Short equipment lifespan; 2. Traditional power distribution cabinets mostly use mounting racks for internal components. Once installed, these racks cannot be adjusted. However, due to usage requirements or the need to prevent components or cables from being exposed outside the cabinet, the mounting racks are often positioned relatively close to the inside of the cabinet. Since operators typically install components on these racks near the cabinet door, installing components on the racks can be cumbersome.

[0005] Therefore, there is an urgent need for a high- and low-voltage distribution cabinet to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high and low voltage distribution cabinet to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A high- and low-voltage switchgear includes a switchgear body, a cabinet door rotatably connected to the outer wall of the switchgear body, and evenly distributed support legs fixedly connected to the outer wall of the switchgear body. It also includes:

[0009] The sliders are symmetrically slidably connected to the inner wall of the power distribution cabinet body. A linkage plate is fixedly connected between the left and right symmetrical sliders, and a longitudinal mounting bracket is fixedly connected between the upper and lower symmetrical sliders. A uniformly distributed transverse mounting bracket is detachably connected between the symmetrical longitudinal mounting brackets.

[0010] The toothed plate is fixedly connected to the inner wall of the distribution cabinet body;

[0011] A position adjustment assembly includes a rotating column rotatably connected between symmetrical sliders on the left side. A gear is fixedly connected to the outer wall of the rotating column, and the gear meshes with a gear plate. A bottom hollow column is fixedly connected to the end of the bottom slider on the left side away from the main body of the distribution cabinet. A top hollow column is fixedly connected to the end of the top slider on the left side away from the main body of the distribution cabinet. A driving hollow column is threadedly connected to the outer wall of the top hollow column. A driven hollow column is rotatably connected to the outer wall of the driving hollow column. A symmetrically distributed limiting plate is fixedly connected to the end of the driven hollow column away from the driving hollow column, and the limiting plate is slidably connected to the gear.

[0012] The drying and dustproof components are installed on the outer wall of the power distribution cabinet.

[0013] As a preferred technical solution of this application, the drying and dustproof assembly includes a dustproof drying box fixedly connected to the outer wall of the power distribution cabinet body, a uniformly distributed dustproof plate slidably connected to the inner wall of the dustproof drying box, a pull plate fixedly connected to the end of the dustproof plate away from the dustproof drying box, a honeycomb heating mesh fixedly connected to the inner wall of the dustproof drying box, a uniformly distributed main guide block fixedly connected to the inner wall of the dustproof drying box, and a uniformly distributed secondary guide block fixedly connected to the inner wall of the dustproof drying box.

[0014] As a preferred technical solution of this application, both the outer wall of the main guide block and the outer wall of the secondary guide block are fixedly connected to the honeycomb heating mesh.

[0015] As a preferred technical solution of this application, the outer walls of the bottom hollow column and the outer walls of the top hollow column are slidably connected to the outer wall of the limiting plate.

[0016] As a preferred technical solution of this application, the rotating column is rotatably connected to the bottom hollow column, and the rotating column is rotatably connected to the top hollow column.

[0017] As a preferred technical solution of this application, an exhaust electric fan is fixedly connected to the outer wall of the power distribution cabinet body, and a symmetrically distributed dustproof net is fixedly connected to the outer wall of the exhaust electric fan.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. The humid air is heated by the honeycomb heating mesh inside the dustproof drying chamber. At the same time, the humid air is guided to flow along the prescribed channel inside the dustproof drying chamber by the main guide block and the secondary guide block, which extends the distance that the humid air flows through. This allows the humid air to cover the surface of the honeycomb heating mesh, thereby fully heating the humid air to form dry air. This prevents the humid air from flowing into the distribution cabinet body due to insufficient drying and causing adverse effects on the distribution cabinet body. This solves the problem that the existing technology lacks a structure for drying humid air, which can easily lead to damage to internal equipment or reduce the service life of equipment in humid weather.

[0021] 2. By using the threaded engagement between the driving hollow column and the top hollow column, the driven hollow column is driven to slide the limiting plate on the bottom hollow column and the top hollow column. This allows the limiting plate to slide out of the bottom hollow column, facilitating the rotation of the driven hollow column. The limiting plate then drives the gear and rotating column to rotate, and the position of the slider is adjusted by the meshing between the gear and the gear plate, thus adjusting the position of the longitudinal and transverse mounting brackets. This allows operators to adjust the position of the mounting brackets according to their operating habits when arranging and installing components on the mounting brackets, i.e., moving them towards the cabinet door. After the operation is completed, the mounting brackets can be easily adjusted back to their initial position, ensuring the reliability of the distribution cabinet. This also solves the problem in existing technology where the mounting brackets inside the traditional distribution cabinet cannot be adjusted once installed, making the subsequent installation of required components on the mounting brackets cumbersome.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0035] like Figure 1-10 As shown, this embodiment proposes a high and low voltage distribution cabinet, including a cabinet body 1, a cabinet door 3 rotatably connected to the outer wall of the cabinet body 1, and evenly distributed support legs 2 fixedly connected to the outer wall of the cabinet body 1, and further including:

[0036] Slider 14 is symmetrically slidably connected to the inner wall of the power distribution cabinet body 1. A linkage plate 15 is fixedly connected between the left and right symmetrical sliders 14. A longitudinal mounting bracket 16 is fixedly connected between the upper and lower symmetrical sliders 14. A uniformly distributed transverse mounting bracket 17 is detachably connected between the symmetrical longitudinal mounting brackets 16.

[0037] Tooth plate 12 is fixedly connected to the inner wall of the power distribution cabinet body 1;

[0038] The position adjustment assembly includes a rotating column 23 rotatably connected between the symmetrical sliders 14 on the left side. A gear 13 is fixedly connected to the outer wall of the rotating column 23, and the gear 13 meshes with a gear plate 12. A bottom hollow column 18 is fixedly connected to the end of the bottom slider 14 on the left side away from the main body 1 of the distribution cabinet. A top hollow column 19 is fixedly connected to the end of the top slider 14 on the left side away from the main body 1 of the distribution cabinet. A driving hollow column 20 is threadedly connected to the outer wall of the top hollow column 19. A driven hollow column 21 is rotatably connected to the outer wall of the driving hollow column 20. Symmetrically distributed limiting plates 22 are fixedly connected to the end of the driven hollow column 21 away from the driving hollow column 20, and the limiting plates 22 are slidably connected to the gear 13. The position of the longitudinal mounting bracket 16 is adjusted as needed. Specifically, the driving hollow column 20 is rotated, and the threaded engagement between the driving hollow column 20 and the top hollow column 19 is achieved. The drive hollow column 20 is moved, which in turn drives the driven hollow column 21 to slide on the outer wall of the bottom hollow column 18 and the top hollow column 19 and the inner wall of the gear 13 through the limiting plate 22. When the limiting plate 22 is still inside the gear 13 but moves out of the outer wall of the bottom hollow column 18, the drive hollow column 20 stops rotating. At this time, the driven hollow column 21 is rotated, which drives the limiting plate 22 to rotate, which in turn drives the gear 13 to rotate along the slider 14 through the rotating column 23. The gear 13 is connected to the toothed plate 12 through meshing, and the rotating column 23 drives the slider 14 to slide in the power distribution cabinet body 1, thereby adjusting the position of the longitudinal mounting bracket 16 and the transverse mounting bracket 17. Then the drive hollow column 20 is returned to its original position, that is, the limiting plate 22 slides back into the outer wall of the bottom hollow column 18 to limit the gear 13, that is, to limit the position of the longitudinal mounting bracket 16.

[0039] The drying and dustproof components are installed on the outer wall of the main body of the power distribution cabinet 1.

[0040] like Figure 1-5As shown, in a preferred embodiment, based on the above method, the drying and dustproof assembly further includes a dustproof drying box 4 fixedly connected to the outer wall of the power distribution cabinet body 1. Dustproof plates 5 are slidably connected to the inner wall of the dustproof drying box 4, and a pull plate 6 is fixedly connected to the end of the dustproof plate 5 away from the dustproof drying box 4. A honeycomb heating mesh 9 is fixedly connected to the inner wall of the dustproof drying box 4, and a main guide block 10 and a secondary guide block 11 are fixedly connected to the inner wall of the dustproof drying box 4, respectively. In use, the exhaust fan 7 rotates to generate exhaust air, which passes through the bottom of the dustproof drying box 4. The air inlet (not shown in the figure) enters the main body of the distribution cabinet 1 and is discharged through the exhaust fan 7. When the exhaust air is humid, it will be filtered by the slidable and detachable dustproof plate 5. Then it will flow along the specific channel formed by the main guide block 10 and the secondary guide block 11. During the flow of humid air, it will repeatedly pass through the honeycomb heating mesh 9 and cover the surface of the honeycomb heating mesh 9, thereby fully heating and drying the humid air. The temperature of the honeycomb heating mesh 9 is set within a reasonable range and should not be lower than 0 degrees. At the same time, the temperature should not be too high to prevent affecting the heat dissipation effect of the main body of the distribution cabinet 1. The specific settings are adjusted according to the installation environment.

[0041] like Figure 4 As shown, in a preferred embodiment, based on the above method, the outer walls of the main guide block 10 and the secondary guide block 11 are both fixedly connected to the honeycomb heating mesh 9. By extending the distance between the main guide block 10 and the secondary guide block 11 and the honeycomb heating mesh 9, the humid air flow distance is extended, which facilitates the thorough drying of the humid air. The main guide block 10 and the secondary guide block 11 are made of heat-conducting material.

[0042] like Figure 9-10 As shown, in a preferred embodiment, based on the above method, the outer walls of the bottom hollow column 18 and the top hollow column 19 are slidably connected to the outer wall of the limiting plate 22. The limiting plate 22 slides into the bottom hollow column 18 to facilitate the limiting and fixing of the gear 13. At the same time, the limiting plate 22 prevents the driven hollow column 21 from rotating along with the driving hollow column 20.

[0043] like Figure 9-10 As shown, in a preferred embodiment, based on the above method, the rotating column 23 is rotatably connected to the bottom hollow column 18 and the top hollow column 19, and the rotating column 23 provides support for the rotation of the gear 13.

[0044] like Figure 1 , Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, an exhaust electric fan 7 is fixedly connected to the outer wall of the power distribution cabinet body 1, and a symmetrically distributed dustproof net 8 is fixedly connected to the outer wall of the exhaust electric fan 7, so as to further protect the power distribution cabinet body 1 from dust.

[0045] Specifically, when using this high and low voltage distribution cabinet: First, adjust the position of the longitudinal mounting bracket 16 as needed. Specifically, rotate the drive hollow column 20. Through the threaded engagement between the drive hollow column 20 and the top hollow column 19, the drive hollow column 20 is moved, thereby causing the driven hollow column 21 to slide through the limiting plate 22 on the outer walls of the bottom hollow column 18 and the top hollow column 19, and on the inner wall of the gear 13. When the limiting plate 22 is still within the gear 13 but has moved out of the outer wall of the bottom hollow column 18, stop rotating the drive hollow column 20. At this point, the rotation... The driven hollow column 21 rotates, causing the limiting plate 22 to rotate. This, in turn, drives the gear 13 to rotate along the slider 14 via the rotating column 23. The gear 13 meshes with the toothed plate 12, causing the slider 14 to slide within the distribution cabinet body 1 via the rotating column 23. This adjusts the positions of the longitudinal mounting bracket 16 and the transverse mounting bracket 17, allowing the mounting brackets to be adjusted according to operational habits during arrangement and installation, i.e., moved towards the cabinet door. After the operation is completed, the position of the mounting bracket is reset, and then the drive hollow column 20 returns to its original position. That is, the limiting plate 22 slides back into the outer wall of the bottom hollow column 18 to limit the gear 13, that is, to limit the position of the longitudinal mounting bracket 16. When in use, the exhaust electric fan 7 rotates to generate exhaust air. The exhaust air enters the distribution cabinet body 1 through the air inlet (not shown in the figure) at the bottom of the dustproof drying box 4 and is discharged through the exhaust electric fan 7. When the exhaust air is humid air, it will be filtered by the slidable and detachable dustproof plate 5. Then it will flow along the specific channel formed by the main guide block 10 and the secondary guide block 11. During the flow of humid air, it will repeatedly pass through the honeycomb heating mesh 9 and cover the surface of the honeycomb heating mesh 9, thereby fully heating and drying the humid air. The temperature of the honeycomb heating mesh 9 is set within a reasonable range and should not be lower than 0 degrees. At the same time, the temperature should not be too high to prevent affecting the heat dissipation effect of the distribution cabinet body 1. The specific temperature is adjusted according to the installation environment to achieve the drying treatment of humid air.

[0046] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
