Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a moisture-proof power cabinet suitable for high humidity environments. Background Technology

[0002] A power distribution cabinet is a device used for power supply and distribution in industrial control systems. It collects electrical energy from the power grid and distributes and controls this energy to various electrical devices through internal electrical components and wiring. Power distribution cabinets typically include circuit breakers, contactors, relays, protective devices, and measuring instruments to protect circuits and equipment and ensure the safe and stable operation of the power system.

[0003] There are two major problems with the design of moisture-proof power cabinets for high-humidity environments: First, the power cabinet is in direct contact with the ground, making it susceptible to moisture penetration, and the fixed-height brackets cannot adapt to different environmental needs, making maintenance inconvenient; second, traditional locking mechanisms have problems such as inadequate sealing, uneven locking force, and insufficient durability, resulting in increased gaps between the door and the cabinet, poor local sealing, and decreased locking performance after long-term use. These defects together weaken the sealing effect of the moisture-proof power cabinet, making it easier for moisture to penetrate and affecting the stable operation and service life of the equipment in high-humidity environments. Utility Model Content

[0004] One objective of this invention is to provide a moisture-proof power cabinet suitable for high-humidity environments. This invention addresses the following issues mentioned in the background: firstly, the power cabinet is in direct contact with the ground, making it susceptible to moisture penetration; secondly, the fixed-height support cannot adapt to different environmental needs, leading to inconvenient maintenance; and thirdly, traditional locking mechanisms suffer from problems such as inadequate sealing, uneven locking force, and insufficient durability. These issues result in increased gaps between the door and cabinet, poor local sealing, and decreased locking performance after long-term use. These defects collectively weaken the sealing effect of the moisture-proof power cabinet, allowing moisture to easily penetrate and affecting the stable operation and service life of the equipment in high-humidity environments.

[0005] A moisture-proof power cabinet suitable for high-humidity environments according to an embodiment of the present invention includes:

[0006] The power cabinet assembly includes a cabinet body and a cabinet door. Buckles are fixedly installed at both the top and bottom ends of one side of the cabinet door. A moisture-proof component is installed inside the cabinet body. A locking mechanism is fixedly installed on the outside of the cabinet body at the position corresponding to the buckles. The cabinet body can be height adjusted by a lifting mechanism.

[0007] The locking mechanism includes a first rotating seat fixed to the cabinet body, a lever rotatably disposed inside the first rotating seat, a support arm rotatably disposed outside the lever, a slider movably disposed inside the support arm, a guide post fixedly disposed on one side of the slider, a latch rotatably disposed on one end of the guide post, and a tension spring disposed outside the guide post.

[0008] The lifting mechanism includes a base, on which a first slide rail and a second slide rail are fixedly installed at the corners on both sides inside the base. A lifting plate and a movable seat are movably installed on the outer sides of the first slide rail and the second slide rail, respectively. A roller and a slab-shaped guide block are fixedly installed on one side of the lifting plate and the top of the movable seat, respectively. The slab-shaped guide block is moved by a drive assembly.

[0009] Preferably, the cabinet door is hinged to rotate with the cabinet body, and an instrument panel and control buttons are fixedly installed on one side of the cabinet door.

[0010] Preferably, the moisture-proof component includes a fan, a dehumidifier box, and a partition plate. The fan, dehumidifier box, and partition plate are all fixedly installed inside the cabinet. A water guide plate is fixedly installed at the bottom of the partition plate, and the dehumidifier box is filled with silica gel desiccant.

[0011] Preferably, a dustproof and moisture-proof board is installed inside the cabinet near the air vent.

[0012] Preferably, the tension spring is located between the slider and the support arm, and the latch and buckle are engaged.

[0013] Preferably, a drain valve is installed inside the cabinet on one side corresponding to the water guide plate.

[0014] Preferably, the slab-shaped guide block has an inclined groove inside, and the roller slides inside the slab-shaped guide block through the inclined groove.

[0015] Preferably, the drive assembly includes a support plate and an electric push cylinder, the support plate is fixedly disposed at the output end of the electric push cylinder, and the support plate is fixedly disposed with respect to the slab-shaped guide block.

[0016] The beneficial effects of this utility model are:

[0017] This invention solves the problem of moisture intrusion caused by poor sealing and uneven locking force in traditional power cabinets by setting up moisture-proof components and locking mechanisms. During use, the fan in the moisture-proof components inside the power cabinet continuously circulates the air inside the cabinet, the silica gel desiccant filled in the dehumidification box efficiently absorbs the moisture in the air, and the partition plate ensures uniform airflow. At the same time, the bottom water guide plate guides the condensate to drain smoothly. In addition, the dustproof and moisture-proof plate installed near the air vent can block the intrusion of external moisture and dust. Then, the lever in the first rotating seat of the locking mechanism cooperates with the support arm, and the movement of the slider and guide column realizes the tight engagement of the latch and buckle. The setting of the tension spring ensures the uniform distribution and long-term maintenance of the locking force, effectively avoiding the increase of the gap between the door and the cabinet and the phenomenon of poor local sealing. Thus, this device not only improves the moisture-proof performance of the power cabinet, but also greatly enhances its sealing stability and long-term durability, ensuring that the equipment can operate stably in high humidity environments and extending its service life.

[0018] This utility model effectively solves the problems of fixed height, poor adaptability, and inconvenient maintenance of traditional power cabinets by setting up a lifting mechanism. During operation, the electric push cylinder in the drive component pushes the support plate, which in turn drives the roller on one side of the lifting plate to slide in the inclined groove in the slab-shaped guide block. This allows the power cabinet to be height-adjusted according to different environmental requirements, avoiding the problem of moisture penetration caused by direct contact with the ground. At the same time, the height-adjustable design also greatly facilitates the maintenance and repair of the equipment, reducing maintenance costs and difficulties. Attached Figure Description

The lever inside the first rotating seat cooperates with the support arm. Through the movement of the slider and the guide post, the latch and the buckle are tightly engaged. The tension spring ensures the uniform distribution and long-term maintenance of the locking force, effectively avoiding the increase of the gap between the door and the cabinet and the phenomenon of poor local sealing. Thus, this device not only improves the moisture-proof performance of the power cabinet;

[0029] The lifting mechanism 4 includes a base 401. A first slide rail 402 and a second slide rail 407 are fixedly installed at the corners on both sides of the base 401. A lifting plate 403 and a movable seat 406 are movably installed on the outer sides of the first slide rail 402 and the second slide rail 407, respectively. A roller 404 and a slab-shaped guide block 405 are fixedly installed on one side of the lifting plate 403 and the top of the movable seat 406, respectively. The slab-shaped guide block 405 is moved by a drive assembly. The drive assembly includes a support plate 408 and an electric push cylinder 409. The support plate 408 is fixedly installed at the output end of the electric push cylinder 409. The support plate 408 and the slab-shaped guide block 405 are fixedly installed. The electric push cylinder in the drive assembly pushes the support plate, thereby causing the roller on one side of the lifting plate to slide in the inclined groove in the slab-shaped guide block. This allows the power cabinet to be height adjusted according to different environmental requirements, avoiding the problem of moisture penetration caused by direct contact with the ground.

[0030] Example 1: Cabinet door 103 is rotatably mounted to cabinet body 101 via hinge 104. Instrument panel 105 and control button 106 are fixedly mounted on one side of cabinet door 103. Moisture-proof component 2 includes fan 201, dehumidifier box 203 and partition plate 204. Fan 201, dehumidifier box 203 and partition plate 204 are all fixedly mounted inside cabinet body 101.

Dustproof and moisture-proof plate 202 is installed inside cabinet body 101 near air vent 102. Fan is responsible for continuously circulating air inside cabinet. Silica gel desiccant filled in dehumidifier box efficiently absorbs moisture in the air. Partition plate ensures uniform airflow. At the same time, bottom water guide plate guides condensate to drain smoothly.

[0031] Example 2: The tension spring 306 is located between the slider 304 and the support arm 303. The tension spring ensures the uniform distribution and long-term maintenance of the locking force. The latch 307 and the buckle 107 are engaged to improve the sealing performance of the power cabinet.

The roller 404 slides inside the slab-shaped guide block 405 through the inclined groove.

[0032] Working principle: A moisture-proof component 2 is installed inside the cabinet 101, including a fan 201, a dehumidifier box 203, and a partition plate 204. The fan 201 continuously circulates the air inside the cabinet, the silica gel desiccant in the dehumidifier box 203 absorbs moisture, the partition plate 204 ensures uniform airflow, the water guide plate 205 guides condensate out, and the dustproof and moisture-proof plate 202 further blocks external moisture and dust. The locking mechanism 3 is fixed to the outside of the cabinet 101. The lever 302 inside the first rotating seat 301 cooperates with the support arm 303. Through the movement of the slider 304 and the guide post 305, the latch 307 and the buckle 107 are tightly engaged. The tension spring 306 is located between the slider 304 and the support arm 303 to ensure locking. The force is evenly distributed and maintained, preventing the gap between the door and the cabinet from increasing and local sealing problems. The lifting mechanism 4 includes a base 401, a first slide rail 402, a second slide rail 407, a lifting plate 403, a moving seat 406, rollers 404, and a slat-shaped guide block 405. An electric push cylinder 409 pushes a support plate 408, causing the rollers 404 in the slat-shaped guide block 405 to slide in the inclined groove, realizing the synchronous lifting of the lifting plate and the moving seat. This allows the power cabinet to be height-adjusted according to different environmental needs, avoiding moisture penetration caused by direct contact with the ground. The drain valve further ensures that the inside of the cabinet is dry. In summary, this device effectively improves the moisture-proof performance, sealing stability, and adaptability of the power cabinet.
