[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: an internally adjustable power cabinet assembly, including a cabinet body 1, a support base 2 fixedly connected to the bottom wall of the cabinet body 1, a mounting frame 3 slidably connected to the cabinet body 1 through a sliding groove opened in its inner wall, the bottom of the mounting frame 3 being attached to and slidably connected to the top of the support base 2, a first mounting component 4 and a second mounting component 5 fixedly connected between the inner walls of the mounting frame 3 respectively, the second mounting components 5 being distributed vertically and horizontally in pairs and located below the first mounting components 4, a cable tray 6 fixedly connected to one end of each of the first mounting components 4 and the second mounting components 5, a desiccant storage cylinder 7 rotatably connected to the top wall of the cabinet body 1, a limit buckle 8 rotatably connected to one side of the inner wall of the cabinet body 1, the limit buckle 8 being at the same height as the desiccant storage cylinder 7, and dustproof plates 9 threadedly connected to both sides of the outer wall of the cabinet body 1 through quick-release bolts.

[0026] The first mounting component 4 consists of a base plate 401, a left side plate 402, a back plate 403, and a right side plate 404. The base plate 401 is fixed to the inner wall of the mounting frame 3. The left side plate 402 and the back plate 403 are vertically distributed and integrally connected with the base plate 401. The right side plate 404 is provided on one side of the left side plate 402. The bottom of the right side plate 404 is slidably connected to the surface of the base plate 401 by a slider extending to the inner groove of the base plate 401. One end of the right side plate 404 is attached to and slides against one side of the back plate 403.

[0027] The second mounting assembly 5 consists of a docking plate 501 and a frame plate 502. The docking plate 501 is located above the frame plate 502 and is spaced apart from it. The docking plate 501 is fixed to the inner wall of the mounting frame 3. The frame plate 502 slides on the inner wall of the mounting frame 3. A reverse screw 503 is provided at the bottom of the frame plate 502 and is rotatably connected to the inner wall of the mounting frame 3. The shaft of one end of the reverse screw 503 is rotatably connected to a first bevel gear 504 and a second bevel gear 505. The first bevel gear 504 and the second bevel gear 505 are meshed together. The shaft of the reverse screw 503 passes through the axis of the first bevel gear 504 and forms an integral connection with it. The reverse screw 503 is rotatably connected to the bottom of the frame plate 502 via a nut threaded on its outer wall and a connecting rod 506.

[0028] In this embodiment, as Figure 4 As shown, the first mounting assembly 4 consists of a group of multiple equidistantly arranged components, with two groups arranged vertically in parallel. Both the left side plate 402 and the right side plate 404 have through holes on their surfaces. A spring is installed in the groove of the base plate 401 corresponding to the position of the bottom slider of the right side plate 404. One end of the spring is fixedly connected to the slider, and the other end is fixedly connected to the groove inside the base plate 401. The right side plate 404 forms an elastic reset structure via the spring and forms an opening and closing structure with the left side plate 402. Because the right side plate 404 forms an elastic reset structure via the spring and forms an opening and closing structure with the left side plate 402, it allows for... This mounting assembly can accommodate the installation of small electrical components of different sizes. When installing small electrical components, the right side plate 404 can be pulled to place the electrical component in the area between the left side plate 402 and the right side plate 404. The right side plate 404 will automatically fit against the outside of the electrical component under the action of the spring. Unlike traditional installation methods, there is no need to precisely match the component size or make cumbersome adjustments. It provides flexible installation space for components of different sizes, greatly improving the adaptability and versatility of the installation. These through holes not only facilitate the passage of electrical wires, but also promote air circulation and help dissipate heat from the electrical components.

[0029] In this embodiment, as Figure 5As shown, the second bevel gear 505 is perpendicular to the first bevel gear 504, and a handle is provided at the axis of the second bevel gear 505. The connecting rods 506 are symmetrically distributed in a figure-eight shape and are rotatably connected to the reverse nut on the outer wall of the corresponding reverse screw 503. At the same time, the connecting rods 506 form a relative motion. The shelf plate 502 forms a lifting structure below the docking plate 501 through the connecting rods 506, and the surface of the docking plate 501 is provided with mounting holes. By rotating the handle, the connecting rods 506 move relative to each other, thereby realizing the lifting and lowering of the shelf plate 502. The distance between the shelf plate 502 and the docking plate 501 can be flexibly adjusted according to the needs of electrical components of different heights, which can adapt to the installation of electrical components of different sizes and avoid the limitation of traditional fixed brackets that cannot adjust the height. It makes full use of the space inside the cabinet and provides a suitable installation space for large electrical components.

[0030] In this embodiment, as Figure 3 As shown, the cable tray 6 has slots for cable routing symmetrically spaced throughout its surface. The cable tray 6 is symmetrically divided into two halves along its central axis. One half has a fixed end fixed to the inner wall of the mounting bracket 3. Simultaneously, the fixed end is slidably connected to the movable end of the other half, which has a protrusion, via a groove on its surface. The fixed end and the sliding end form an opening and closing structure. The symmetrical distribution of the cable tray 6 along its central axis, with the fixed and movable ends forming an opening and closing structure, greatly improves operational flexibility. When a large number of wires need to be placed into the cable tray 6, the movable end can be opened for quick and easy insertion. This overcomes the difficulties of traditional cable tray 6, where the entire tray is fixed, making it difficult to insert and thread large quantities of wires. It allows for easy insertion and removal of wires, facilitating installation and maintenance and reducing cable routing difficulties caused by space constraints.

[0031] In this embodiment, as Figure 2As shown, the support base 2 has a fan 10 embedded in its surface through a slot, with half of the fan 10 located below the mounting frame 3. The desiccant storage cylinder 7 is located in the area between the mounting frame 3 and the cabinet 1 door panel. The layout of the fan 10 helps to efficiently dissipate heat from the mounting frame 3 and the electrical components installed on it. The airflow generated from bottom to top can carry away the heat generated by the electrical components in a timely manner, preventing heat accumulation and ensuring that the electrical components operate within a suitable temperature range, thereby improving the overall operational stability of the power cabinet. The desiccant storage cylinder 7 is located in the area between the mounting frame 3 and the cabinet 1 door panel. This layout spatially isolates the desiccant storage cylinder 7 from the electrical components. On the one hand, the desiccant storage cylinder 7 can effectively absorb the humid air inside the cabinet 1, maintaining a dry environment inside the cabinet 1 and preventing damage to the electrical components due to moisture. On the other hand, separating it from the electrical components can prevent collisions or interference that the desiccant storage cylinder 7 may cause to the electrical components during installation, replacement, or operation, ensuring the normal operation and safety of the electrical components.

[0032] In this embodiment, as Figure 6 As shown, the bottom of the desiccant storage cylinder 7 is threaded with a cap, and both the desiccant storage cylinder 7 and its cap have a through circular hole. The desiccant storage cylinder 7 can be rotated 90° via the engagement structure between the bottom cap and the limiting buckle 8, and a spring is provided on one side of the limiting buckle 8. This 90° rotation of the desiccant storage cylinder 7 via the engagement structure between the bottom cap and the limiting buckle 8 provides significant protection for the electrical components inside the power cabinet during maintenance. When maintenance is required on the electrical components within the mounting bracket 3, the desiccant storage cylinder 7 can be rotated 90°, and the limiting buckle... The locking mechanism of 8 prevents the desiccant storage cylinder 7 from shaking unnecessarily and affecting operation, keeping it away from electrical components. This avoids obstructing electrical components during maintenance, facilitates maintenance work, and prevents damage to electrical components due to collisions. The through holes in the desiccant storage cylinder 7 and its cap facilitate air circulation, allowing the internal desiccant to better absorb the humid air inside the cabinet 1. This ensures full contact between the desiccant and the air inside the cabinet 1, improving the effectiveness of the desiccant. At the same time, the threaded cap makes it very convenient to replace the desiccant.

[0033] In this embodiment, as Figure 1 and Figure 2As shown, ventilation holes are provided on both sides of the outer wall of the cabinet 1 corresponding to the position of the dustproof plate 9. A quadrilateral strip-shaped insert is provided at one end of the dustproof plate 9, and a slot for inserting the strip-shaped insert is provided on the surface of the cabinet 1 corresponding to the position of the strip-shaped insert. The dustproof plate 9 can prevent large particles of dust in the outside air from entering the power cabinet through the ventilation holes, which plays a good role in dust prevention. It effectively protects the electrical components in the power cabinet and reduces the risk of performance degradation and short circuits of electrical components caused by dust accumulation. It achieves a balance between heat dissipation and dust prevention functions. It is connected to the outside of the cabinet 1 by a combination of plugging and threading, which greatly improves the tightness of the connection and also enables quick disassembly.

[0034] The method of use and advantages of this utility model: The internally adjustable power cabinet assembly operates as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first, open the protective door panel on the outside of cabinet 1, slide and pull the mounting bracket 3 to the appropriate position, and begin installing smaller electrical components, such as relays and fuses, using the first mounting assembly 4. The installation steps are as follows: pull the right side panel 404 to increase the space between it and the left side panel 402, place the power component in the area between the right side panel 404 and the left side panel 402. Under the action of the spring structure, the right side panel 404 will automatically fit against the outside of the electrical component according to the size of the internal component, thus fixing the electrical component. This installation method is different from the traditional screw installation method and is more flexible and convenient. For larger electrical components, such as circuit breakers and transformers, place them in the lower area, i.e., the position of the second mounting assembly 5. The installation steps are as follows: Adjust the height of the bracket 502 from the docking plate 501 according to the height of the electrical components. By rotating the handle on the outside of the second bevel gear 505, the first bevel gear 504 is driven to rotate. The rotation of the first bevel gear 504 will cause the reverse screw 503 to rotate. The reverse nut corresponding to the outer wall of the reverse screw 503 moves relative to each other under the transmission structure. The connecting rod 506 connected to the reverse nut will drive the bracket 502 to rise or fall. Adjust the bracket 502 to a suitable height. Finally, fix the electrical components mounted on the surface of the bracket 502 to the through holes on the surface of the docking plate 501 with screws using connecting pieces to complete the installation of large electrical components. After the installation of all electrical components is completed, the wiring is connected and arranged. The wiring connecting the electrical components is fixed and organized through the cable tray 6. The two halves of the cable tray 6 form an opening and closing structure. It can be opened during use to put the wiring into the tray. Unlike the traditional method of threading guide wires, this structure increases the convenience of wiring and the flexibility of operation. During the use of the power cabinet, the bottom fan 10 and the drying package The desiccant packs inside storage cylinder 7 work in conjunction with the fan 10 to dissipate heat from the power cabinet, carrying away the heat generated by the electrical components and preventing heat buildup. The desiccant packs in storage cylinder 7 also absorb humid air inside cabinet 1 to maintain a dry environment and prevent damage to electrical components due to moisture. The cap of storage cylinder 7 is threaded, allowing for easy replacement of the desiccant packs. When maintenance is required on the electrical components inside mounting bracket 3, to avoid damage to the desiccant packs... When the storage cylinder 7 collides with the electrical components, it rotates the storage cylinder 7 to a 90° angle. The limit buckle 8 engages with the bottom cover of the storage cylinder 7 to ensure that the storage cylinder 7 does not interfere with maintenance operations. The dustproof plates 9 on both sides of the cabinet 1 can intercept large dust particles in the outside air and prevent them from entering the power cabinet. The dustproof plates 9 are connected to the outside of the cabinet 1 by quick-release threads. During routine maintenance of the internal electrical components, the dustproof plates 9 can be removed and cleaned at the same time to ensure the dustproof effect of the dustproof plates 9.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
