Description

Technical Field

[0001] This invention relates to the field of power distribution and electrical control technology, specifically to a power supply cabinet. Background Technology

[0002] With the continuous improvement of industrial automation, power supply cabinets, as important carriers for power distribution, control, and protection, are widely used in power distribution systems, industrial production lines, and various complete sets of equipment. Power supply cabinets typically integrate core components such as circuit breakers, power modules, relays, control units, and auxiliary electrical components. Their operational stability directly affects the safety and continuity of the entire system. Because electrical components continuously generate heat during operation, the structural design of power supply cabinets must not only meet electrical safety regulations and installation and maintenance requirements, but also consider good heat dissipation and structural reliability to ensure stable operation of internal components within a reasonable temperature rise range.

[0003] Existing power cabinets typically employ a box-type structure, consisting of a cabinet frame, side panels, top panel, bottom panel, and front and rear doors forming an enclosed space. Internal mounting plates or rails are used to secure various electrical components. For heat dissipation, ventilation holes, louvers, or axial fans are usually installed on the cabinet. Through natural ventilation or forced air cooling, outside air enters the cabinet, exchanges heat with the heat-generating components, and is then exhausted, thereby lowering the internal temperature. Maintenance primarily involves opening the cabinet doors or removing panels to inspect and replace internal components. The overall technical principle revolves around structural support, electrical isolation, and air convection cooling, achieving the basic operational requirements of the power cabinet through a rational arrangement of installation space and ventilation paths.

[0004] During long-term operation, the existing power cabinet structure still has room for improvement in terms of ventilation and maintenance coordination. For example, dust easily accumulates in ventilation areas while air is circulating, thus affecting ventilation efficiency. Furthermore, when core components need to be replaced or repaired, the numerous internal structural layers limit operating space. In addition, because the airflow path inside the cabinet mainly relies on natural convection or fixed fan layout, the airflow organization is relatively simple, making it difficult to effectively control the heat dissipation path based on the actual heat distribution. The combined effect of these factors may, to some extent, affect the thermal management effectiveness and maintenance convenience of the power cabinet. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power cabinet that solves the problems of dust accumulation and blockage in ventilation areas, inconvenience in replacing and maintaining core components, disordered airflow organization inside the cabinet, and difficulty in controlling the heat dissipation path.

The sliding shaft is slidably connected inside the sliding groove. A locking block is rotatably connected to the inside of the first support column.

[0009] Preferably, the adjusting mechanism includes a first slide rail, a first slider slidably connected to the outer side of the first slide rail, a threaded rod threadedly connected to the inner side of the first slide rail, one end of the threaded rod rotatably connected to the outer side of the first slider, the first slider slidably connected to the inner side of a rotating block, a limiting groove being formed inside the rotating block, the first slider slidably connected to the inner side of the limiting groove, a rotating shaft being fixedly connected to the inner side of the rotating block, a first guide plate being fixedly connected to the outer side of the rotating shaft, a third guide plate and a second guide plate being rotatably connected to the inner side of the power cabinet body, the third guide plate and the second guide plate being disposed on both sides of the first guide plate, a second connecting rod being rotatably connected to the outer side of the third guide plate, the second connecting rod being rotatably connected to the outer side of the first guide plate, a first connecting rod being rotatably connected to the outer side of the first guide plate, and the first connecting rod being rotatably connected to the outer side of the second guide plate.

[0010] Preferably, the sliding column is slidably connected to the inner side of the limiting block, and the outer side of the cleaning brush is provided with multiple bristles for cleaning the filter screen.

[0014] Preferably, a fan is installed on the top of the power cabinet body. The fan is used to introduce cold air from outside into the power cabinet body to cool the inside of the power cabinet body.

[0015] Preferably, the power cabinet body is provided with two sets of heat dissipation meshes on the outside. The heat dissipation meshes are used to form a stable ventilation channel on the side of the power cabinet body, so that external air can enter or exit from both sides of the power cabinet body, thereby providing a lateral ventilation path for the airflow inside the cabinet body.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1.

This structure eliminates the need for separate disassembly of the filter screen or manual cleaning, and can complete the dust removal action during the door opening operation, effectively reducing dust accumulation at the ventilation holes and filter screen, maintaining the unobstructed state of the ventilation channel, thereby ensuring the stability of the air exchange efficiency inside the cabinet, and helping to maintain a good heat dissipation environment for the core components.

[0018] 2. This invention, through the design of a support mechanism, allows core components to extend outward along the second slide rail under the drive of a cylinder, forming a stable support with the cooperation of the first support column, the third connecting rod, the sliding shaft, and the locking block. This structure ensures that the components are reliably supported during maintenance or replacement, preventing swaying or tilting due to their own weight or uneven force during extension, improving the safety and convenience of maintenance operations, shortening maintenance time, and enhancing the overall maintenance efficiency of the power cabinet.

[0019] 3. This invention achieves structural control of the airflow path inside the cabinet through the coordinated adjustment of the threaded rod, the first slider, the rotating block, and multiple guide plates in the adjustment mechanism. By changing the combination of guide plate angles, the cold air introduced by the fan can flow through different areas in a preset direction, forming an adjustable airflow distribution channel. This improves the airflow organization inside the cabinet, allowing heat to be carried away from the heat-generating component area more systematically, enhancing heat dissipation, and improving the thermal management capability and stability of the power cabinet during operation.

Detailed Implementation

[0030] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a power cabinet, including a power cabinet body 1. A cabinet door 2 is rotatably connected to the outside of the power cabinet body 1. The cabinet door 2 is used to open and close the internal space of the cabinet, and simultaneously triggers the operation of a linkage wiping mechanism 5 to achieve synchronous cleaning of the filter screen 513. The linkage wiping mechanism 5 is provided on the inside of the power cabinet body 1. The linkage wiping mechanism 5 causes the wiping component to move along the inner surface of the ventilation hole during the opening of the cabinet door 2, so as to achieve synchronous wiping and cleaning of the ventilation hole. A support mechanism 6 is provided on the inside of the power cabinet body 1 to keep the core components 7 stably supported in the extended state, thereby facilitating the replacement and maintenance of the components. An adjustment mechanism 3 is also provided on the outside of the power cabinet body 1 to make the airflow flow through different areas according to a preset path, so as to achieve structural control of the airflow direction inside the power cabinet body 1.

[0031] Specifically, the power cabinet body 1 and the rotating cabinet door 2 are used to manage the opening and closing of the internal space of the cabinet and to clean the ventilation area during the opening and closing process. A linkage wiping mechanism 5 is installed inside the power cabinet body 1 to periodically wipe the filter screen 513 and the ventilation hole area, reducing the impact of dust accumulation on heat dissipation efficiency. A support mechanism 6 is also installed inside the power cabinet body 1 to provide stable support when the core components 7 are in an extended state, improving the safety and convenience of maintenance and replacement operations. An adjustment mechanism 3 is installed on the outside of the power cabinet body 1 to guide and control the internal airflow path in zones, optimizing the heat dissipation airflow organization from a structural perspective.

[0032] Please see the appendix Figure 1 - Appendix Figure 4 In a preferred embodiment of the present invention, the linkage erasing mechanism 5 includes a motor 503, which is disposed inside the power cabinet body 1 and serves as a power source to drive the first bevel gear 504 to rotate. The output end of the motor 503 is fixedly connected to the first bevel gear 504. A second connecting rod 505 is fixedly connected to the outside of the first bevel gear 504, transmitting rotational power to the first connecting rod 501. The other end of the second connecting rod 505 is rotatably connected to the first connecting rod 501, and the other end of the first connecting rod 501 is rotatably connected to a connecting block 502. The connecting block 502 is fixedly connected to the inside of the cabinet door 2. A second bevel gear 507 is meshed with the outside of the first bevel gear 504, engaging with and driving the first bevel gear 504. The eccentric plate 508 rotates, and a first connecting plate 506 is fixedly connected to the inner side of the power cabinet body 1. A second bevel gear 507 is rotatably connected to the inner side of the first connecting plate 506. An eccentric plate 508 is fixedly connected to the other end of the second bevel gear 507. A second connecting plate 509 is rotatably connected to the outer side of the eccentric plate 508. The second connecting plate 509 is rotatably connected to the outer side of the eccentric plate 508 and is used to transmit the eccentric motion to the slide column 511. The slide column 511 is fixedly connected to the outer side of the second connecting plate 509. A limit block 510 is fixedly connected to the inner side of the power cabinet body 1. A cleaning brush 512 is fixedly connected to the outer side of the slide column 511. A filter screen 513 is fixedly connected to the inner side of the power cabinet body 1. The filter screen 513 is fixed to the inner side of the power cabinet body 1 and is used to perform preliminary filtration of the air entering the cabinet and is the target of the cleaning brush 512. The cleaning brush 512 is slidably connected to the outer side of the filter screen 513.

[0033] Specifically, the linkage wiping mechanism 5 uses a motor 503 as its core power source. Power distribution and reversing transmission are achieved through the first bevel gear 504 and the second bevel gear 507, causing the eccentric plate 508 to undergo continuous eccentric motion. This drives the second connecting plate 509 and the sliding column 511 to move stably back and forth, thereby driving the cleaning brush 512 to move periodically along the surface of the filter screen 513. The first connecting rod 501, the second connecting rod 505, and the connecting block 502 are used to achieve coordinated control of the cabinet door 2's movement and the internal transmission mechanism. The first connecting plate 506 and the limiting block 510 are used to ensure motion stability and trajectory limitation. Through the above structural configuration, the filter screen 513 is cleaned synchronously during equipment operation, reducing the impact of dust accumulation on heat dissipation efficiency and improving the stability of the internal operating environment of the power cabinet body 1.

[0034] Please see the appendix Figure 2 - Appendix Figure 7 In a preferred embodiment of the present invention, the support mechanism 6 includes a second slide rail 602, which is fixed to the inner side of the power cabinet body 1 and serves to guide the second slider 603. The second slide rail 602 is fixedly connected to the inner side of the power cabinet body 1, and the second slider 603 is slidably connected to the inner side of the second slide rail 602. A cylinder 604 is fixedly connected to the inner side of the power cabinet body 1, and its output end is connected to the second slider 603 to provide a linear pushing force. The output end of the cylinder 604 is fixedly connected to the outer side of the second slider 603. A second support column 605 is fixedly connected to the bottom of the second slider 603. A first support column 601 is rotatably connected to the inner side of the support column 605.

A sliding groove 608 is provided inside the first support column 601. A third connecting rod 606 is rotatably connected to the inner side of the second slider 603. A sliding shaft 609 is fixedly connected to the other end of the third connecting rod 606. The sliding shaft 609 is slidably connected inside the sliding groove 608 and fixedly connected to the third connecting rod 606 to realize the angle adjustment of the support column. A locking block 607 is rotatably connected to the inner side of the first support column 601.

[0035] Specifically, the support mechanism 6 forms a linear guide mechanism with the second slide rail 602 and the second slider 603, which, together with the cylinder 604, provides a stable linear driving force, enabling the core component 7 to be moved smoothly outward during maintenance or replacement. The second support column 605 and the first support column 601 constitute a deployable load-bearing assembly, forming a bottom support structure when the core component 7 is extended. The third connecting rod 606 and the sliding shaft 609 move in coordination within the sliding groove 608, realizing the angle adjustment and posture stability of the first support column 601. The locking block 607 is used to limit and lock the support state after it is deployed. The overall structure realizes the coordinated guidance, support, and limiting of the core component 7 during the outward movement process, improving the stability and safety of maintenance operations.

[0036] Please see the appendix Figure 1 - Appendix Figure 9 In a preferred embodiment of the present invention, the adjustment mechanism 3 includes a first slide rail 301, which is fixedly connected to the inner side of the power cabinet body 1 to provide a linear guide path for the first slider 302, ensuring its motion stability during the adjustment process. The first slider 302 is slidably connected to the outer side of the first slide rail 301, and a threaded rod 306 is threadedly connected to the inner side of the first slide rail 301. The threaded rod 306 is threaded to the inner side of the first slide rail 301 and drives the first slider 302 to move axially through rotation, thereby achieving precise adjustment of the guide plate angle. One end of the threaded rod 306 is rotatably connected to the outer side of the first slider 302, and the first slider 302 is slidably connected to the inner side of the rotating block 303. A limiting groove 304 is formed inside the rotating block 303 to limit the movement trajectory of the first slider 302, preventing derailment or deviation and ensuring the stability of the adjustment action. Inside the limiting groove 304, a rotating shaft 305 is fixedly connected to the inner side of the rotating block 303. A first guide plate 307 is fixedly connected to the outer side of the rotating shaft 305. The first guide plate 307 is fixedly connected to the outer side of the rotating shaft 305, and its angle changes with the rotating shaft 305. It is used to guide the airflow entering the power cabinet body 1 in the main direction. A third guide plate 309 and a second guide plate 308 are rotatably connected to the inner side of the power cabinet body 1. The third guide plate 309 and the second guide plate 308 are set on both sides of the first guide plate 307. A second connecting rod 311 is rotatably connected to the outer side of the third guide plate 309. The second connecting rod 311 is rotatably connected between the first guide plate 307 and the third guide plate 309. It is used to realize the linkage adjustment between multiple guide plates. The second connecting rod 311 is rotatably connected to the outer side of the first guide plate 307. A first connecting rod 310 is rotatably connected to the outer side of the first guide plate 307. The first connecting rod 310 is rotatably connected to the outer side of the second guide plate 308.

[0037] Specifically, the adjustment mechanism 3 forms a linear guide mechanism with the first slide rail 301 and the first slider 302, and, in conjunction with the rotational drive of the threaded rod 306, achieves precise axial displacement adjustment of the slider. A limiting groove 304 is provided inside the rotating block 303 to constrain the movement trajectory of the first slider 302, ensuring stability and repeatability during the adjustment process. The rotating shaft 305 drives the first guide plate 307 to rotate synchronously, achieving structural control of the main airflow direction. The second guide plate 308 and the third guide plate 309 are distributed on both sides of the first guide plate 307, and form a linkage mechanism through the first connecting rod 310 and the second connecting rod 311, enabling multiple guide plates to maintain coordinated angle changes during adjustment, thereby achieving zoned guidance and flow direction optimization of the airflow path inside the power cabinet.

[0038] Please see the appendix Figure 1 - Appendix Figure 9 In a preferred embodiment of the present invention, the sliding column 511 is slidably connected to the inner side of the limiting block 510, the cleaning brush 512 is provided with multiple bristles on the outer side for cleaning the filter screen 513, the core component 7 is fixedly installed on the top of the second slider 603, and multiple control switches are provided on the outer side of the core component 7, the sliding shaft 609 is slidably connected to the inner side of the sliding groove 608, the snap-fit ​​block 607 is in contact with the sliding shaft 609, the rotating shaft 305 is rotatably connected to the inner side of the power cabinet body 1, the first guide plate 307 is provided with an air guide groove on the outer side for guiding the airflow direction, the top of the power cabinet body 1 is equipped with a fan 4, the fan 4 is used to introduce external cold air into the power cabinet body 1 to cool the inside of the power cabinet body 1, and two sets of heat dissipation mesh are provided on the outer side of the power cabinet body 1. The heat dissipation mesh is used to form a stable ventilation channel on the side of the power cabinet body 1, so that external air can enter or exit from both sides of the power cabinet body 1, thereby providing a lateral ventilation path for the airflow inside the cabinet.

[0039] Specifically, the sliding column 511 slides linearly inside the limiting block 510 to ensure the stability of the cleaning action's stroke and position constraint. The cleaning brush 512 has multiple bristles on its outer side to scrape and clean dust particles adhering to the surface of the filter screen 513. The core component 7 is fixedly mounted on the top of the second slider 603, and multiple control switches are located on the outer side of the core component 7 to switch and control the equipment's operating status. The sliding shaft 609 slides inside the sliding groove 608, and the locking block 607 engages with the sliding shaft 609 to achieve position locking and release. The rotating shaft 305 is rotatably mounted inside the power cabinet body 1, and an air guide groove is opened on the outer side of the first guide plate 307 to guide airflow in a specific direction. A fan 4 is installed on the top of the power cabinet body 1 to introduce external cool air. Two sets of heat dissipation meshes are provided on the outer side of the power cabinet body 1 to form lateral ventilation channels.

[0040] Working principle: In the use of the power cabinet of the present invention, the power cabinet body 1 serves as the installation and support base. Through the cooperation of the cabinet door 2, the linkage wiping mechanism 5, the support mechanism 6 and the adjustment mechanism 3, the power cabinet can realize the functions of ventilation and heat dissipation, component maintenance and support, and airflow guidance. During operation, the fan 4 set on the top of the power cabinet body 1 introduces external cold air into the cabinet. The air flows inside the cabinet and is discharged through two sets of heat dissipation nets set on the outside of the power cabinet body 1, thereby forming a basic ventilation path inside the cabinet and providing heat dissipation conditions for the normal operation of the internal core components 7.

[0041] When cabinet door 2 needs to be opened, motor 503 starts, driving the first bevel gear 504 and the second connecting rod 505 on its outer side to rotate in conjunction with the first connecting rod 501. Through connecting block 502, it drives cabinet door 2 to open and close synchronously. The first bevel gear 504 meshes with the second bevel gear 507, causing the second bevel gear 507 to rotate and drive the eccentric plate 508 to move. The eccentric plate 508 pushes the slide column 511 to slide back and forth along the direction of the limit block 510 through the second connecting plate 509, so that the cleaning brush 512 fixedly connected to the outer side of the slide column 511 slides relative to the surface of the filter screen 513, thereby wiping and cleaning the filter screen 513 synchronously during the opening of cabinet door 2.

[0042] Secondly, when the core component 7 needs to be replaced or repaired, the support mechanism 6 starts to work. The cylinder 604 set inside the power cabinet body 1 pushes the second slider 603 to move along the direction of the second slide rail 602. The second slider 603 drives the core component 7 fixedly installed on its top to extend outward from its original installation position along the preset guide direction. During the movement of the second slider 603, the staff turns the first support column 601 to rotate. At the same time, the third connecting rod 606 drives the sliding shaft 609 to slide in the sliding groove 608. With the help of the locking block 607, the position of the first support column 601 is limited, so that the first support column 601 provides stable support for the core component 7 in the extended state, thereby ensuring the support stability of the component in the extended state and facilitating replacement, repair and other operations. When it is necessary to retract, the locking block 607 is turned to release the locking of the sliding shaft 609, and the first support column 601 can be retracted.

[0043] During the operation of the power cabinet, the fan 4 draws cold air from outside into the power cabinet body 1. The adjustment mechanism 3 is used to structurally control the airflow direction inside the cabinet. By rotating the threaded rod 306, the threaded rod 306 drives the first slider 302 to slide along the first slide rail 301. The first slider 302 is displaced in the limiting groove 304 inside the rotating block 303, thereby driving the rotating block 303 to rotate around the rotating shaft 305 fixedly connected to its inner side, causing the first guide plate 307 fixed on the outer side of the rotating shaft 305 to change angle. At the same time, under the linkage of the first connecting rod 310 and the second connecting rod 311, the second guide plate 308 and the third guide plate 309 set on both sides of the first guide plate 307 rotate synchronously, so that multiple guide plates form different angle combinations, thereby guiding and distributing the airflow direction entering the power cabinet body 1, so that the airflow flows through different areas according to the preset path, and realizes the structural control of the airflow direction inside the power cabinet body 1.
