Description

Technical Field

[0001] The invention belongs to the technical field of electric control cabinets, and in particular relates to a dehumidifying and moisture-proof ship electric control cabinet. Background Art

[0002] During the operation of the ship, the electrical control cabinet plays a vital role. It is responsible for controlling and monitoring various electrical equipment on the ship. However, due to the special environment of the ship, the electrical control cabinet faces severe challenges of dehumidification and moisture-proofing. The ship sails in the marine environment and the air humidity is usually high. Especially in some specific sea areas and climatic conditions, high-humidity air can easily enter the electrical control cabinet, causing the electrical components to become damp. Therefore, it is necessary to use a ship electrical control cabinet that can dehumidify and moisture-proof.

[0003] However, during the use of existing dehumidification and moisture-proof ship electrical control cabinets, the dehumidification of the bottom of the cabinet is often ignored. Due to the principle that hot air rises and cold air sinks, relatively cold and humid air is easy to accumulate at the bottom of the cabinet, and the air flow in the electrical control cabinet is relatively slow at the bottom of the cabinet, which is not conducive to the discharge of moisture. The long-term accumulation of moisture will form water accumulation, which will gradually erode the bottom of the electrical components, causing the insulation performance of the components to decrease, and increasing the risk of faults such as short circuits and leakage. Summary of the invention

[0004] The purpose of the present invention is to provide a dehumidifying and moisture-proof ship electrical control cabinet. By arranging a dehumidification mechanism at the bottom of the cabinet, the problem of often neglecting the dehumidification of the bottom of the cabinet is solved. Due to the principle that hot air rises and cold air sinks, relatively cold and humid air is easy to accumulate at the bottom of the cabinet, and the air flow in the electrical control cabinet is relatively slow at the bottom of the cabinet, which is not conducive to the discharge of moisture. The long-term accumulation of moisture will form water accumulation, which will gradually erode the bottom of the electrical components, resulting in a decrease in the insulation performance of the components and an increased risk of faults such as short circuits and leakage.

[0015] The present invention has the following beneficial effects:

[0016] 1. By arranging the cabinet bottom cleaning mechanism, when it is necessary to dehumidify the device, the motor can be started. The motor drives the C-shaped support frame to move back and forth in the trapezoidal chute 1 through the reciprocating lead screw and the support plate. When the C-shaped support frame moves back and forth, it will drive the drying roller on the first rotating shaft to move back and forth. When the first rotating shaft moves back and forth, it will drive the drying roller to rotate under the action of the gear and the rack, so as to efficiently dehumidify the bottom of the electrical control cabinet. The back-and-forth movement of the drying roller can cover all areas of the bottom of the electrical control cabinet to ensure that there are no missed corners. At the same time, during the movement, due to the action of the gear and the rack, it rotates, further increasing the contact area and frequency with the bottom, so as to more comprehensively and efficiently remove the moisture at the bottom. Compared with the static dehumidification method, this dynamic combination of movement and rotation can continuously process the moisture at different positions, avoid the accumulation of moisture in local areas, and greatly improve the dehumidification effect.

[0017] 2. By arranging the filter plate cleaning component, since the rotation of the third rotating shaft will drive the cam to rotate. When the convex part of the cam rotates to the U-shaped adapter block, the convex part of the cam will press on the U-shaped adapter block, so that the filter plate moves backward, and forces the telescopic rod and the spring to be in a compressed state to generate elastic force. When the convex part of the cam disengages from the U-shaped adapter block, the filter plate will be reset under the elastic force of the spring, and the filter plate vibrates in this way to avoid the blockage of the filter plate, so as to effectively prevent the blockage of the filter plate and ensure that the air can always pass through the filter plate smoothly. This enables the air inside the device to circulate continuously, ensures the continuous renewal of the air inside the electrical control cabinet, provides good air circulation conditions for dehumidification and moisture prevention, and good air circulation helps to maintain a stable environment inside the electrical control cabinet, avoiding problems such as local overheating or excessive humidity caused by poor air circulation, so as to ensure the stable operation of electrical equipment.

Compared with the static dehumidification method, this dynamic combination of movement and rotation can continuously process the moisture at different positions, avoid the accumulation of moisture in local areas, and greatly improve the dehumidification effect.

[0030] The hot air dehumidification mechanism 3 includes a blowing component 31, a filter plate cleaning component 32 and a heating component 33.

By arranging the blowing component 31, the temperature in the cabinet can be increased, thereby accelerating the evaporation of moisture in the cabinet. Compared with dehumidification under natural conditions, this method greatly shortens the time required for dehumidification and improves the dehumidification efficiency. Continuous hot air blowing can keep the electrical control cabinet in a relatively dry state at all times. Even in a humid ship environment, it can effectively prevent the intrusion of external moisture and enhance the moisture-proof performance of the electrical control cabinet.

[0031] The filter plate cleaning assembly 32 includes two trapezoidal slide grooves 321 provided on the inner wall of the air inlet pipe 107, and the filter plates 322 are slidably connected to the inner walls of the two trapezoidal slide grooves 321. The rear side of the air inlet pipe 107 is fixedly connected to two L-shaped support plates 323, and the front sides of the two L-shaped support plates 323 are fixedly connected to telescopic rods 324, and the front sides of the two telescopic rods 324 are fixedly connected to the filter plates 322. The outer walls of the two telescopic rods 324 are sleeved with springs 325, and the front sides of the two springs 325 are fixedly connected to the filter plates 322.

The front side of the filter plate 322 is fixedly connected to two U Two cams 327 are fixedly connected to the outer wall of the spring 325, and the two cams 327 are respectively matched with the two U-shaped adapter blocks 326. By setting the filter plate cleaning component 32, it is possible to effectively prevent the filter plate 322 from being blocked, ensuring that the air can always pass through the filter plate 322 smoothly, which allows the air in the device to circulate continuously, ensuring that the air in the electrical control cabinet is constantly renewed, providing good air circulation conditions for dehumidification and moisture-proofing, and good air circulation helps to maintain a stable environment in the electrical control cabinet, avoiding problems such as local excessive temperature or excessive humidity caused by poor air circulation, thereby ensuring the stable operation of the electrical equipment.

[0032] The heating component 33 includes a heating ring 331 fixedly connected to the inner wall of the rear side of the electrical control cabinet 1, a heating coil 332 is arranged in the heating ring 331, and a heat conducting plate 333 is fixedly connected to the inner wall of the heating coil 332. By setting the heating component 33, the heat conducting plate 333 can be quickly heated to the required temperature to provide the necessary heat for the hot air dehumidification of the device.

[0033] A specific application of this embodiment is as follows: When in use, first place the device in the corresponding position, start the motor 223. The motor 223 drives the U-shaped support frame 212 to move back and forth in the trapezoidal chute 211 through the reciprocating screw rod 222 and the support plate 221. When the U-shaped support frame 212 moves back and forth, it drives the drying roller 214 on the rotating shaft 213 to move back and forth. When the rotating shaft 213 moves back and forth, it drives the drying roller 214 to rotate under the action of the gear 216 and the rack 215, so as to efficiently dehumidify the bottom of the electrical control cabinet 1. The back-and-forth movement of the drying roller 214 can cover all areas of the bottom of the electrical control cabinet 1 to ensure that there are no missed corners. At the same time, during the movement, due to the action of the gear 216 and the rack 215, it rotates, further increasing the contact area and frequency with the bottom, so as to more comprehensively and efficiently remove the moisture at the bottom. Compared with the static dehumidification method, this dynamic combination of movement and rotation can continuously process the moisture at different positions, avoid the accumulation of moisture in local areas, and greatly improve the dehumidification effect. When starting the motor 223, turn on the heating component 33 at the same time, so that the heating coil 332 starts to heat. After heating, the temperature will be conducted on the heat conduction plate 333. The material of the heat conduction plate 333 is copper alloy, which has excellent heat conduction performance. When the reciprocating screw rod 222 rotates, the reciprocating screw rod 222 will drive the rotating shaft 315 to rotate through the bevel gear 317. When the rotating shaft 315 rotates, it will drive the fan 314 on the rotating shaft 213 to rotate through the bevel gear 316, blow air on the heat conduction plate 333 with heat, and blow the hot air into the electrical control cabinet 1 to heat and dehumidify the inside of the electrical control cabinet 1. Blowing the hot air into the electrical control cabinet 1 can increase the temperature inside the cabinet, thereby accelerating the evaporation of the moisture inside the cabinet. Compared with the dehumidification in the natural state, this method greatly shortens the time required for dehumidification and improves the dehumidification efficiency. Continuous blowing of hot air can keep the inside of the electrical control cabinet in a relatively dry state all the time. Even in a humid ship environment, it can effectively prevent the intrusion of external moisture and enhance the moisture-proof performance of the electrical control cabinet. And because the rotation of the rotating shaft 315 will drive the cam 327 to rotate. When the convex part of the cam 327 rotates to the U-shaped adapter block 326, the convex part of the cam 327 will push against the U-shaped adapter block 326, so that the filter plate 322 moves backward, and forces the telescopic rod 324 and the spring 325 to be in a compressed state to generate elastic force. When the convex part of the cam 327 leaves the U-shaped adapter block 326, the filter plate 322 will be reset under the action of the elastic force of the spring 325. In this way, the filter plate 322 vibrates back and forth, so as to avoid the blockage of the filter plate 322, making it possible to effectively prevent the blockage of the filter plate 322 and ensure that air can always pass through the filter plate 322 smoothly. This enables the air inside the device to circulate continuously, ensuring that the air inside the electrical control cabinet is constantly updated, providing good air circulation conditions for dehumidification and moisture-proof, and good air circulation helps to maintain a stable environment inside the electrical control cabinet.Avoid problems such as local over-temperature or over-humidity caused by poor air circulation, thereby ensuring the stable operation of electrical equipment.
