Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for distribution boxes, specifically a dehumidification device for conventional distribution boxes. Background Technology

[0002] As a crucial component of the power system, distribution boxes are widely used in industrial and civil buildings. The stable operation of their internal electrical components directly impacts the security of power supply. However, during long-term use, humid air can easily enter the distribution box, causing internal components to become damp and short-circuit. Simultaneously, dust adhering to the component surfaces not only affects heat dissipation but may also lead to a decline in insulation performance.

[0003] Existing dehumidification methods for electrical distribution boxes mostly use fixed dehumidification panels or small fans, which have the following shortcomings: 1. Once the dehumidifier plates become saturated, the machine needs to be shut down and replaced, which affects the continuous operation of the distribution box; 2. Dehumidifier panels tend to accumulate dust over long-term use, reducing dehumidification efficiency and making cleaning inconvenient; 3. Dust is not thoroughly filtered when outside air enters, which can easily contaminate the dehumidification components and internal components of the distribution box; 4. Lack of automatic cleaning and drying mechanisms, resulting in high manual maintenance costs.

[0004] To address the aforementioned problems, this invention proposes a dehumidification device for conventional distribution boxes that can automatically replace dehumidification components, simultaneously clean the dustproof structure, and also has a drying function, thereby overcoming the deficiencies of existing technologies. Summary of the Invention

[0005] The present invention aims to provide a dehumidification device for conventional distribution boxes, which realizes the alternating use of dehumidification components, automatic cleaning and drying, and simultaneous cleaning of dustproof panels, ensuring that the air inside the distribution box remains dry and reducing manual maintenance costs.

[0022] The second component (5) includes a reset damping rod (501) fixedly installed on the lower inner wall of the housing (1), a second cover plate (502) fixedly installed above the reset damping rod (501), and the reset damping rod (501) can drive the second cover plate (502) to reset; a circular plate (503) is fixedly installed at the end of the second cover plate (502), a second motor (504) is fixedly installed inside the circular plate (503), a rotating plate (505) is fixedly installed at the output end of the second motor (504), a cleaning plate (506) is fixedly installed on the side of the rotating plate (505), and several flexible toothed plates (507) are evenly installed on the surface of the cleaning plate (506). The second motor (504) can drive the cleaning plate (506) to rotate back and forth to clean the impurities below the dehumidification filter plate (305); The second cover plate (502) has cleaning grooves (508) at both ends. A collection box (509) can be detachably installed below the second cover plate (502). The collection box (509) is connected to the cleaning grooves (508), and the cleaned impurities can fall into the collection box (509) through the cleaning grooves (508). Several ventilation holes (510) are provided on the surface of the collection box (509) to balance the air pressure inside and outside the collection box (509). The second cover plate (502) has placement grooves (511) at both ends for fitting the dehumidifying filter plate (305). A threaded sleeve (512) is fixedly installed below the second cover plate (502). A threaded rod (513) is installed on the inner wall of the threaded sleeve (512). A driven gear (514) is fixedly installed below the threaded rod (513). The driven gear (514) is movably installed below the inner wall of the housing (1). When the second cover plate (502) moves up and down, it can drive the threaded sleeve (512) to rotate, thereby driving the driven gear (514) to rotate.

[0023] The driven component (6) includes a toothed plate (601) adapted to be installed on one side of the driven gear (514). Support rods (602) are fixedly installed at both ends of the toothed plate (601). A sweeping plate (603) is fixedly installed above the support rods (602). The sweeping plate (603) is in contact with the bottom of the dustproof plate (7). When the driven gear (514) rotates, it can drive the toothed plate (601) to move left and right, thereby driving the sweeping plate (603) to clean the dust on the surface of the dustproof plate (7).

[0024] In addition, an infrared sensor is installed inside the air box (2) at the position corresponding to the dehumidification device (3), and is electrically connected to the control device to accurately position the rotational displacement of the dehumidification filter plate (305) to ensure dehumidification efficiency. The control device is electrically connected to the dehumidification motor (301), the electric telescopic rod (401), the first motor (403), the second motor (504), the dryer (408), and the infrared sensor to control the coordinated operation of each component.

[0025] The working principle is as follows: The entire dehumidification device is precisely installed inside a conventional distribution box by the locking slide rail (9) fixed by bolts on both sides of the box (1) and the air box (2). During the installation process, the locking slide rail (9) limits the device to prevent it from shaking inside the distribution box. After installation, the device divides the internal space of the distribution box into upper and lower sections, creating a reasonable space for subsequent air circulation and dehumidification. In the initial stage of device operation, external air enters naturally from below the wind box (2). First, the air comes into contact with the dustproof plate (7) welded and fixed to the lower inner wall of the wind box (2). The porous structure of the dustproof plate (7) can not only effectively adsorb and block dust and impurities in the air to prevent dust from contaminating the subsequent dehumidification filter plate (305), but also play a preliminary buffering role for the incoming air, so that the air flows more evenly to the dehumidification filter plate (305). After being filtered by the dustproof plate (7), the air continues to flow upward and comes into full contact with the dehumidification filter plate (305) in the wind box (2). The dehumidification filter plate (305) uses its own moisture-absorbing material to efficiently adsorb the moisture in the air and complete the dehumidification process. The dehumidified dry air then enters the power distribution box through the wind box (2) to provide a dry operating environment for the electrical equipment in the power distribution box and ensure air circulation efficiency. As dehumidification continues, the dehumidifying filter plates (305) inside the air box (2) are switched periodically. After receiving the switching signal, the control center starts the dehumidifying motor (301) which is fixed to the inner wall of the air box (2) and the box (1) by bolts. The output end of the dehumidifying motor (301) drives the dehumidifying connecting plate (302) to rotate through a key connection. The dehumidifying connecting plate (302) then drives the X-shaped plates (303) welded and fixed on both sides to rotate synchronously. During the rotation, the dehumidifying filter plates (305) that were originally saturated in the air box (2) are accurately rotated into the box (1) to await subsequent cleaning and drying. At the same time, the dehumidifying filter plates (305) that have been cleaned and dried in the box (1) are rotated into the air box (2) to take over the dehumidification work from the saturated filter plates. During the entire rotation process, the rotation displacement is monitored in real time by an infrared sensor installed on the inner wall of the air box (2) to ensure that the X-shaped plates (303) rotate accurately and avoid the dehumidification efficiency of the device being affected by displacement deviation. After confirming that the saturated dehumidifying filter plate (305) has been rotated to the designated position inside the housing (1), the control center starts the electric telescopic rod (401) which is fixed to the upper part of the inner wall of the housing (1) by bolts. The electric telescopic rod (401) extends and pushes the first cover plate (402) welded to one end to move downward. The first cover plate (402) first contacts the upper surface of the dehumidifying filter plate (305), and then, under the continuous thrust of the electric telescopic rod (401), it continues to press downward, gradually pushing the dehumidifying filter plate (305) out of the dehumidifying slot (304) opened on the X-shaped plate (303). During this process, the first damping rod (306) welded to both ends of the bolt plate (307) which is bolted to both ends of the dehumidifying filter plate (305) and the fixing plate (306) which is welded to one side of the fixing plate (306) is bolted to both ends of the dehumidifying filter plate (305). 08), the card plate (309) will stretch and move due to the squeezing of the internal shape of the dehumidification slot (304), and the card plate (309) is provided with a ball bearing at one end, which facilitates disassembly and insertion, and helps the dehumidification filter plate (305) to move out of the dehumidification slot (304) smoothly. As the first cover plate (402) continues to move down, the lower surface of the dehumidification filter plate (305) finally comes into close contact with the second cover plate (502) which is fixed above the reset damping rod (501) by welding. At this time, the first cover plate (402) and the second cover plate (502) work together to form a relatively sealed space on the upper and lower sides of the dehumidification filter plate (305), which effectively prevents the dust and moisture generated during the subsequent cleaning process from spreading to other areas inside the box (1) and ensures the cleanliness of the cleaning work; After the dehumidifying filter plate (305) is sealed, the control center starts the first motor (403) which is fixed above the first cover plate (402) by bolts. The output end of the first motor (403) drives the first gear (404) to rotate through the key connection. The first gear (404) then drives the second gear (405) meshing with it on both sides to rotate synchronously. The rotating rod (406) fixed below the shaft of the second gear (405) through the key connection rotates together with the second gear (405). The rotating scraper (407) welded and fixed on the side of the rotating rod (406) also rotates, and thoroughly cleans the upper surface of the dehumidifying filter plate (305), scraping away the condensed water and adsorbed dust and impurities generated by moisture absorption on the upper surface of the filter plate. The aging-resistant rubber pad set below the rotating rod (406) prevents the rotating scraper (407) from scratching the dehumidifying filter plate (305) during the cleaning process, thus completing the cleaning of the upper surface. While cleaning the upper surface of the dehumidifying filter plate (305), the control center simultaneously starts the second motor (504) which is fixed in the circular plate (503) at the end of the second cover plate (502) by bolts. The output end of the second motor (504) drives the rotating plate (505) to rotate through a key connection. The cleaning plate (506) welded and fixed on the side of the rotating plate (505) rotates back and forth with the rotating plate (505). When the cleaning plate (506) rotates to the limit position at one end, it will automatically rotate in the opposite direction. The surface of the cleaning plate (506) is bonded with a flexible toothed plate (507) that is evenly fixed. With its own elasticity, it closely adheres to the lower surface of the dehumidifying filter plate (305) to efficiently clean the dust and stubborn stains on the lower surface. The elasticity of the flexible toothed plate (507) can not only ensure the cleaning effect, but also effectively avoid scratching the lower surface of the dehumidifying filter plate (305). During the process of the cleaning plate (506) reciprocating to clean the lower surface of the dehumidifying filter plate (305), the scraped dust and impurities will gradually move towards the cleaning grooves (508) opened at both ends of the second cover plate (502) under the pushing action of the cleaning plate (506), and fall into the collection box (509) below which is detachably connected by a buckle through the cleaning grooves (508). The ventilation holes (510) opened on the surface of the collection box (509) can effectively prevent the dust from clumping due to the humid environment inside the box, making it easier for the staff to disassemble and clean the collection box (509) later. At the same time, the placement grooves (511) opened at both ends of the second cover plate (502) are used for the placement position of the bolt plate (307). During the double-sided cleaning of the dehumidifying filter plate (305), the control center simultaneously starts the dryer (408), which is symmetrically fixed above the first cover plate (402) with bolts. The hot air generated by the dryer (408) is delivered to the sealed space between the first cover plate (402) and the dehumidifying filter plate (305) through its air outlet, which is welded to the first cover plate (402) and extends into the first cover plate (402). This continuously dries the upper surface of the dehumidifying filter plate (305). At the same time, the hot air flows in the sealed space and also dries the lower surface of the dehumidifying filter plate (305). The surface is dried to a certain extent, and with the air circulation formed by the vent holes (510) of the collection box (509), the drying speed of the dehumidifying filter plate (305) is accelerated, ensuring that the dehumidifying filter plate (305) can quickly restore its moisture absorption capacity and prepare for the next rotation into the wind box (2) for dehumidification. In addition, a corrugated ventilation pipe (409) is welded through the top of the first cover plate (402). Because it is extensible, it can adapt to the lifting and lowering movement of the first cover plate (402). During the drying process, the moisture generated in the sealed space can be discharged in time, further improving the drying efficiency. As the second cover plate (502) moves up and down with the dehumidification filter plate (305), the threaded sleeve (512) welded and fixed below the second cover plate (502) will also move up and down synchronously. Since the inner wall of the threaded sleeve (512) is threadedly matched with the threaded rod (513), the up and down movement of the threaded sleeve (512) will drive the threaded rod (513) to rotate around its own axis. The driven gear (514) is welded and fixed below the threaded rod (513). The driven gear (514) is movably mounted on the lower inner wall of the housing (1) through a bearing to ensure smooth rotation. It rotates together with the threaded rod (513). The driven gear (514) then drives the toothed plate (601) that is matched and meshed with it to move back and forth. The support rod (602) welded and fixed at both ends moves synchronously with the toothed plate (601). The sweeping plate (603) welded and fixed above the support rod (602) also slides back and forth under the dustproof plate (7). The sweeping plate (603) is made of soft wear-resistant material. During the sliding process, it can effectively clean the dust and impurities attached to the lower surface of the dustproof plate (7), prevent the dustproof plate (7) from being blocked due to dust accumulation, and ensure its filtration and ventilation effect. When the second cover plate (502) is at the top and bottom positions, the two sets of sweeping plates (603) will be at the two ends of the dustproof plate (7) respectively, and the two sets of sweeping plates (603) are each responsible for cleaning half of the area of ​​the dustproof plate (7), ensuring that the entire lower surface of the dustproof plate (7) can be thoroughly cleaned without any dead corners. After the cleaning and drying of the saturated dehumidifying filter plate (305) is completed, the control center issues a reset command. First, the electric telescopic rod (401) retracts, causing the first cover plate (402) to move upward, gradually releasing the pressure on the dehumidifying filter plate (305). Subsequently, under the elastic restoring force of the reset damping rod (501) fixed by bolts below it, the second cover plate (502) pushes the dehumidifying filter plate (305) upward to gradually move it back to its initial position. During the retraction of the dehumidifying filter plate (305), the clamping plates (309) at both ends of the dehumidifying filter plate (305) are engaged. Under the reset elastic force of the first damping rod (308), it re-fits with the dehumidification slot (304) on the X-shaped plate (303), and firmly fixes the dehumidification filter plate (305) on the X-shaped plate (303), waiting for the next rotation into the air box (2) for dehumidification. Thus, the device completes a complete cycle of "dehumidification-switching-cleaning-drying-reset". As the dehumidification demand of the distribution box continues, the device will continuously repeat the above cycle process, continuously providing stable and efficient dehumidification services for the distribution box, and ensuring the safe and reliable operation of the electrical equipment in the distribution box.
