Description

Technical Field

[0001] This utility model relates to the field of power cabinets, and in particular to a moisture-proof and airtight power cabinet door panel. Background Technology

[0002] Power cabinets, as crucial enclosure structures in power systems used for the centralized installation and protection of power equipment (such as transformers, circuit breakers, and contactors), are widely used in industrial production, buildings, data centers, and other scenarios. Their core function is to provide a stable operating environment for internal electrical components, preventing damage from external dust, moisture, foreign objects, and accidental contact, thereby ensuring the safe and stable operation of the power system. The power cabinet door, a key component, not only seals the cabinet and protects the internal equipment but also needs to facilitate easy opening and routine maintenance. In practical applications, the tightness of the fit between the door and the main body of the power cabinet directly affects the cabinet's protective performance.

[0003] However, due to limitations in manufacturing precision, wear and tear on components caused by prolonged opening and closing, and assembly errors, traditional power cabinet doors often fail to completely seal the contact points with the main body of the power cabinet, easily creating gaps. These gaps cause numerous problems: moisture and humidity from the outside air can easily penetrate the cabinet interior. When the humidity reaches a certain level, it may cause internal electrical components to short-circuit due to moisture, and metal parts to corrode, severely affecting the lifespan and operational safety of the power equipment. Simultaneously, dust and debris can also enter through the gaps, accumulating on the equipment surface, affecting heat dissipation efficiency and increasing the risk of malfunction. Therefore, this application proposes a moisture-proof and sealed power cabinet door to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a moisture-proof and airtight power cabinet door panel, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A moisture-proof and airtight power cabinet door includes a power cabinet protective door. An elastic compression assembly is fixedly installed on the inner front wall of the power cabinet protective door. The elastic compression assembly consists of springs and a first rectangular frame. Several springs are fixedly installed at the front end of the first rectangular frame. A moisture-proof and airtight assembly is fixedly installed at the rear end of the first rectangular frame. The moisture-proof and airtight assembly consists of a second rectangular frame, connecting plates, a non-woven fabric frame-shaped bag, and a desiccant. Four connecting plates are symmetrically fixedly installed on the inner wall of the second rectangular frame. The non-woven fabric frame-shaped bag is fixedly installed at the rear end of the second rectangular frame. The desiccant is filled inside the non-woven fabric frame-shaped bag. An mounting component is rotatably installed on the connecting plate. The moisture-proof and airtight assembly is installed at the rear end of the first rectangular frame via the mounting component. The mounting component consists of a connecting shaft, a handle, a baffle, and a limiting plate. The handle is fixedly installed at the rear end of the connecting shaft, the baffle is fixedly installed at the front end of the connecting shaft, and the limiting plate is fixedly installed at the front end of the baffle.

[0006] Preferably, the protective door of the power cabinet is installed on the main body of the power cabinet.

[0007] Preferably, the spring on the elastic compression assembly is fixedly installed on the front inner wall of the power cabinet protective door, and the outer wall of the first rectangular frame is in contact with the four inner walls of the power cabinet protective door.

[0008] Preferably, the second rectangular frame and the non-woven frame-shaped bag on the moisture-proof sealing assembly are in contact with the four inner walls of the power cabinet protective door.

[0009] Preferably, the connecting plate of the moisture-proof sealing assembly has a shaft hole, which passes through the connecting plate from front to back.

[0010] Preferably, the connecting shaft on the mounting component is rotatably mounted in the shaft hole, the handle is located behind the connecting plate, the baffle is located in front of the connecting plate, and the limiting plate is located in front of the first rectangular frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing an elastic compression assembly consisting of a spring and a first rectangular frame inside the power cabinet protective door, and a moisture-proof sealing assembly consisting of a second rectangular frame, a connecting plate, a non-woven fabric frame-shaped bag, and a desiccant on the elastic compression assembly, when the power cabinet protective door is closed, the spring generates an elastic force to push the first rectangular frame, thereby causing the moisture-proof sealing assembly to move backward. This allows the non-woven fabric frame-shaped bag of the moisture-proof sealing assembly to tightly adhere to the inner side of the joint between the power cabinet protective door and the main body of the power cabinet. The flexible properties of the non-woven fabric frame-shaped bag fill any gaps, achieving a physical seal. At the same time, the desiccant inside the non-woven fabric frame-shaped bag can absorb moisture that has entered through gaps or was already present inside the cabinet. This dual effect effectively improves the moisture-proof sealing performance of the power cabinet, reduces the impact of moisture and humidity on internal electrical components, and lowers the risk of short circuits. The system reduces the risk of malfunctions such as road damage and corrosion, extending the equipment's service life. Furthermore, the first rectangular frame, the second rectangular frame, and the non-woven fabric frame-shaped bag all contact the four inner walls of the power cabinet's protective door, further restricting moisture and dust from entering through the gaps between the power cabinet's protective door and these components, enhancing the overall protective effect. By installing an installation component on the connecting plate consisting of a connecting shaft, handle, baffle, and limiting plate, the moisture-proof sealing component and the elastic compression component can be easily separated. When the desiccant's adsorption capacity is saturated or the non-woven fabric frame-shaped bag becomes worn, simply turn the handle to rotate the connecting shaft, causing the limiting plate to move out of its limiting position relative to the first rectangular frame, allowing the entire moisture-proof sealing component to be removed and replaced. The operation is simple and convenient, requiring no complex tools, facilitating daily maintenance and component updates, and ensuring long-term effectiveness of the moisture-proof sealing performance.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-6As shown, a moisture-proof and airtight power cabinet door panel includes a power cabinet protective door 1. An elastic compression assembly 3 is fixedly installed on the inner front wall of the power cabinet protective door 1. The elastic compression assembly 3 consists of springs 7 and a first rectangular frame 6. Several springs 7 are fixedly installed at the front end of the first rectangular frame 6. A moisture-proof and airtight assembly 4 is fixedly installed at the rear end of the first rectangular frame 6. The moisture-proof and airtight assembly 4 consists of a second rectangular frame 8, connecting plates 9, a non-woven fabric frame-shaped bag 10, and a desiccant 11. Four connecting plates 9 are symmetrically fixedly installed on the inner wall of the second rectangular frame 8. The non-woven fabric frame-shaped bag 10 is fixedly installed at the rear end of the second rectangular frame 8. The desiccant 11 is filled inside the non-woven fabric frame-shaped bag 10. The connecting plates 9 are rotatably mounted on the connecting plates 9. The moisture-proof sealing assembly 4, equipped with mounting component 5, is installed at the rear end of the first rectangular frame 6. Mounting component 5 consists of a connecting shaft 12, a handle 13, a baffle 14, and a limiting plate 15. The handle 13 is fixedly installed at the rear end of the connecting shaft 12, the baffle 14 is fixedly installed at the front end of the connecting shaft 12, and the limiting plate 15 is fixedly installed at the front end of the baffle 14. An elastic compression assembly 3, consisting of a spring 7 and the first rectangular frame 6, is installed inside the power cabinet protective door 1. A moisture-proof sealing assembly 4, consisting of a second rectangular frame 8, a connecting plate 9, a non-woven frame-shaped cloth bag 10, and a desiccant 11, is installed on the elastic compression assembly 3. When the power cabinet protective door 1 is closed, the spring 7 generates an elastic force to push the first rectangular frame 6. This causes the moisture-proof sealing component 4 to move backward, allowing the non-woven fabric frame-shaped bag 10 of the moisture-proof sealing component 4 to tightly adhere to the inner side of the joint between the power cabinet protective door 1 and the power cabinet body 2. The flexible nature of the non-woven fabric frame-shaped bag 10 fills any gaps, achieving a physical seal. Simultaneously, the desiccant 11 inside the non-woven fabric frame-shaped bag 10 absorbs moisture that has entered through gaps or was already present inside the cabinet. This dual action effectively improves the moisture-proof sealing performance of the power cabinet, reduces the impact of moisture and humidity on internal electrical components, lowers the risk of short circuits, corrosion, and other malfunctions, and extends the equipment's service life. Furthermore, the first rectangular frame 6, the second rectangular frame 8, and the non-woven fabric frame-shaped bag 10 all contact the four inner walls of the power cabinet protective door 1. It can further restrict moisture and dust from entering through the gap between the inside of the power cabinet protective door 1 and these components, enhancing the overall protection effect. By setting the mounting part 5 on the connecting plate 9, which consists of a connecting shaft 12, a handle 13, a baffle 14 and a limiting plate 15, the moisture-proof sealing component 4 and the elastic compression component 3 can be easily separated. When the desiccant 11 is saturated or the non-woven frame bag 10 is worn, simply turn the handle 13 to rotate the connecting shaft 12, so that the limiting plate 15 can be rotated out of the limiting state that cooperates with the first rectangular frame 6, and the moisture-proof sealing component 4 can be removed and replaced as a whole. The operation is simple and convenient, without complicated tools, which facilitates daily maintenance and component replacement, and ensures that the moisture-proof sealing performance is effective for a long time.

[0016] Specifically, the power cabinet protective door 1 is installed on the power cabinet body 2. The spring 7 on the elastic compression assembly 3 is fixedly installed on the inner front wall of the power cabinet protective door 1. The outer wall of the first rectangular frame 6 is in contact with the inner walls of the four sides of the power cabinet protective door 1. The second rectangular frame 8 and the non-woven frame-shaped cloth bag 10 on the moisture-proof sealing assembly 4 are both in contact with the inner walls of the four sides of the power cabinet protective door 1. The connecting plate 9 on the moisture-proof sealing assembly 4 has a shaft hole 16, which passes through the connecting plate 9 from front to back. The connecting shaft 12 on the mounting part 5 is rotatably installed in the shaft hole 16. The handle 13 is located behind the connecting plate 9. The baffle 14 is located in front of the connecting plate 9. The limiting plate 15 is located in front of the first rectangular frame 6.

[0017] When using this power cabinet, first ensure that the power cabinet protective door 1 is open. Install the relevant electrical components into the power cabinet body 2. After installation, close the power cabinet protective door 1. At this time, the spring 7 in the elastic compression assembly 3 will be compressed due to the closing of the power cabinet protective door 1, generating an elastic force. This force pushes the first rectangular frame 6 to move backward, thereby driving the moisture-proof sealing assembly 4 connected to the first rectangular frame 6 to move backward synchronously, so that the non-woven frame-shaped cloth bag 10 in the moisture-proof sealing assembly 4 tightly fits against the power cabinet protective door 1 and the... Inside the seams of the main body 2 of the power cabinet, the flexible properties of the non-woven frame-shaped cloth bag 10 are used to fill any gaps that may exist at the seams, achieving a physical seal. Simultaneously, the desiccant 11 inside the non-woven frame-shaped cloth bag 10 absorbs moisture that may have entered through the gaps or was already present inside the cabinet. Furthermore, the first rectangular frame 6, the second rectangular frame 8, and the non-woven frame-shaped cloth bag 10 all contact the four inner walls of the power cabinet protective door 1, further restricting moisture and dust from entering through the gaps between the inside of the power cabinet protective door 1 and these components. When maintenance of the power cabinet interior is required, the direct... Simply open the power cabinet protective door 1. At this time, the elastic force of the spring 7 is released, causing the first rectangular frame 6 and the moisture-proof sealing component 4 to move forward and reset. When the desiccant 11 becomes saturated or the non-woven frame bag 10 is worn and needs to be replaced, first open the power cabinet protective door 1, then grasp the handle 13 in the mounting part 5 and turn it. The handle 13 drives the connecting shaft 12 to rotate in the shaft hole 16 of the connecting plate 9. The rotation of the connecting shaft 12 simultaneously drives the baffle 14 and the limiting plate 15 to rotate. When the limiting plate 15 rotates to... When the moisture-proof sealing assembly 4 is no longer in the position that limits its movement with the first rectangular frame 6, it can be removed from the first rectangular frame 6 as a whole. Then, align the new moisture-proof sealing assembly 4 with the first rectangular frame 6, so that the limiting plate 15 passes through the corresponding position on the first rectangular frame 6. Then, turn the handle 13 in the opposite direction to drive the connecting shaft 12, the baffle 14 and the limiting plate 15 to rotate until the limiting plate 15 rotates to the position that limits its movement with the first rectangular frame 6 (the limiting plate 15 rotates to contact the front end of the first rectangular frame 6), thus completing the installation and replacement of the moisture-proof sealing assembly 4.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
