Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a dehumidifying and moisture-proof integrated distribution box. Background Technology

[0002] In the field of power equipment, distribution boxes often suffer from moisture, short circuits, or corrosion of internal components due to excessively high ambient humidity, which seriously affects the stability of equipment operation.

[0003] Traditional moisture-proof solutions for distribution boxes typically employ a single dehumidification method, such as heating or ventilation dehumidification alone. This is insufficient for high-humidity environments (such as coastal areas or underground spaces) and consumes a lot of energy. Nowadays, to improve dehumidification efficiency, dual dehumidification methods are generally used, such as condensation dehumidification combined with adsorption dehumidification. While this can achieve good dehumidification results, in some high-humidity environments, the adsorption material is prone to excessive humidity, which affects its adsorption effect. Consequently, the adsorption material needs to be replaced frequently, greatly increasing the maintenance frequency of the distribution box. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This application provides a dehumidification and moisture-proof integrated distribution box, which solves the problem that when dehumidifying in high-humidity environments, the adsorption material is prone to excessive humidity, which affects its adsorption effect and requires frequent replacement of the adsorption material, greatly increasing the maintenance frequency of the distribution box.

[0023] Through the series design of condensation dehumidification of the first dehumidification component 21 and adsorption dehumidification of the second dehumidification component 23, the air undergoes two stages of dehumidification treatment, significantly improving dehumidification efficiency. The first dehumidification component 21 can remove most of the liquid water, and the second dehumidification component 23 further captures gaseous water molecules, which is especially suitable for high humidity environments, ensuring that the humidity inside the equipment box 12 remains stable within a safe range for a long time. At the same time, in the second dehumidification component 23, the moisture-absorbing cloth 235 is continuously wound up: the drive motor 2371 drives the winding roller 234 to rotate, automatically replacing the saturated moisture-absorbing cloth 235, avoiding the problem of traditional fixed adsorption materials failing due to excessive humidity.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This invention discloses a dehumidifying and moisture-proof integrated distribution box.

[0026] According to the appendix Figure 1-13 As shown, it includes: The enclosure unit 1 includes an outer shell 11 and an equipment box 12 installed inside the outer shell 11. Ventilation holes are provided at the top and bottom of the equipment box 12. Air intake unit 2 and air exhaust unit 3 are respectively installed at the bottom and top of equipment box 12. The air inside equipment box 12 is replaced by the air intake unit 2 and air exhaust unit 3 and the air vents of equipment box 12. The air intake unit 2 includes a first dehumidification component 21, an air intake fan component 22, and a second dehumidification component 23. The air intake fan component 22 is fixedly installed between the first dehumidification component 21 and the second dehumidification component 23, and can drive the airflow to pass through the first dehumidification component 21 and the second dehumidification component 23 and enter the equipment box 12. The first dehumidification component 21 and the second dehumidification component 23 can dehumidify the airflow sequentially.

[0027] Through the tandem design of condensation dehumidification of the first dehumidification component 21 and adsorption dehumidification of the second dehumidification component 23, the air undergoes two stages of dehumidification treatment, significantly improving dehumidification efficiency. The first dehumidification component 21 can remove most of the liquid water, while the second dehumidification component 23 further captures gaseous water molecules, making it particularly suitable for high-humidity environments and ensuring that the humidity inside the equipment box 12 remains stable within a safe range for a long time.

[0028] Furthermore, both sides of the outer casing 11 are provided with air inlets 111 that are open to the inside and outside. A filter screen 113 is embedded on the outside of the outer casing 11, and the filter screen 113 is located on the side of the air inlet 111. An exhaust hole 112 that is open to the inside and outside is provided on the top of the outer casing 11. The exhaust unit 3 is located between the vent hole and the exhaust hole 112 on the top of the equipment box 12.

[0029] A filter screen 113 is embedded on the outside of the air inlet 111 to block dust and particulate matter from entering the equipment box 12 and extend the life of internal components. The air intake unit 2 and the exhaust unit 3 are located at the bottom and top of the equipment box 12, respectively, forming a unidirectional airflow from bottom to top, avoiding the backflow of hot and humid air and improving dehumidification efficiency.

[0030] Specifically disclosed, the first dehumidification component 21 includes a dehumidification chamber 211, a liquid collector 212, heat exchange tubes 213, and a condensate collection frame 216. The liquid collector 212 is installed on the outside of the dehumidification chamber 211. The heat exchange tubes 213 are arranged on the dehumidification chamber 211 in multiple rows. Both ends of the heat exchange tubes 213 are connected to the liquid collector 212 to realize the circulation of refrigerant inside the heat exchange tubes 213. The bottom and top of the dehumidification chamber 211 are provided with connecting ports, and the condensate collection frame 216 is located directly below the bottom connecting port of the dehumidification chamber 211. The condensate collection frame 216 is connected to a drain pipe extending to the outside.

[0031] Furthermore, the dehumidification chamber 211 has a heat exchange cavity 214 inside. Multiple rows of heat exchange fins 215 are installed on the inner wall of the heat exchange cavity 214. The multiple rows of heat exchange fins 215 are all sleeved on the outside of the heat exchange tube 213, and the multiple rows of heat exchange fins 215 are staggered. The heat exchange fins 215 are connected by a V-shaped plate 2151 and a top plate 2152. The top plate 2152 is connected to the top of the V-shaped plate 2151, and a cooling cavity 2153 is formed between the top plate 2152 and the V-shaped plate 2151. The heat exchange tube 213 is inserted into the cooling cavity 2153.

[0032] The heat exchange tubes 213 are stacked to increase the contact area between air and refrigerant, improving heat exchange efficiency and rapidly reducing the air temperature below the dew point, thus promoting water vapor condensation. Meanwhile, the heat dissipation fins 215, composed of V-shaped plates 2151 and a top plate 2152, are arranged in a staggered pattern to create a multi-channel airflow path, extending the residence time of air in the condensation zone. The V-shaped plates 2151 also guide condensate to the bottom connection, preventing water accumulation. The condensate collection box 216 directly collects and discharges the condensate, preventing secondary evaporation of liquid water into the equipment housing 12 and reducing maintenance frequency.

[0033] Specifically disclosed, the second dehumidification component 23 includes a movable housing 231, an unwinding roller 233, a winding roller 234, and a moisture-absorbing fabric 235. The movable housing 231 is configured as a frame structure without a lid or bottom, and receiving slots 232 are provided on both sides of the upper part of the movable housing 231. The unwinding roller 233 and the winding roller 234 are respectively placed in the receiving slots 232 on both sides. The moisture-absorbing fabric 235 is connected between the unwinding roller 233 and the winding roller 234. Fixing components 236 are installed on both sides of the upper part of the movable housing 231. The fixing components 236 cooperate with the receiving slots 232 to fix the positions of the unwinding roller 233 and the winding roller 234. The end of the winding roller 234 is connected to a drive component 237.

[0034] The storage tank 232 of the storage and take-up roller 234 is provided with a drainage hole and is connected to the condensate collection frame 216 through a connecting pipe to prevent water accumulation in the storage tank 232.

[0035] It should be emphasized that the moisture-absorbing fabric 235 can be made of shrink-resistant wool or microporous hydrophobic polyester. The material characteristics of shrink-resistant wool or microporous hydrophobic polyester enable it to absorb moisture, but it is not easy to cause capillary action, which would cause the moisture-absorbing fabric 235 on the unwinding roller 233 to be spread by moisture.

[0036] Shrink-resistant wool is covered with scales, creating a valve-like effect. Moisture must overcome the resistance of the scales to diffuse, significantly slowing down capillary propagation. Simultaneously, the natural three-dimensional crimp creates irregular pores between fibers, disrupting continuous capillary formation and further limiting directional moisture conduction. Microporous hydrophobic polyester forms micropores on the surface of polyester fibers through phase separation, then coats them with a fluorinated hydrophobic coating. The micropores adsorb moisture through surface tension, achieving directional moisture absorption. The hydrophobic coating blocks the continuous aqueous phase between fibers, inhibiting capillary conduction. The aforementioned shrink-resistant wool or microporous hydrophobic polyester materials are existing products, so they will not be described in detail here.

[0037] Specifically disclosed, the fixing component 236 includes a cover plate 2361, a baffle 2362, a fixing plate 2363, and a limiting block 2364. The baffle 2362 is installed at the bottom of the cover plate 2361, the fixing plate 2363 is installed at the front and rear of the cover plate 2361, and the limiting block 2364 is fixedly set at the bottom of the fixing plate 2363. The fixing plate 2363 is fixedly connected to the movable housing 231 by bolts. The cover plate 2361 covers the upper part of the receiving groove 232, and the bottom of the baffle 2362 and the movable housing 231 are in contact with the upper and lower surfaces of the moisture-absorbing fabric 235. The bottom of the limiting block 2364 is in contact with the inner wall of the receiving groove 232 and the ends of the unwinding roller 233 and the take-up roller 234.

[0038] The baffle 2362 serves two purposes: it limits the moisture-absorbing fabric 235 and prevents moisture from directly contacting the unwinding roller 233 and the take-up roller 234. Meanwhile, the bottom of the limiting block 2364 fits against the inner wall of the receiving groove 232 and the ends of the unwinding roller 233 and the take-up roller 234, thus enabling the unwinding roller 233 and the take-up roller 234 to rotate stably.

[0039] Specifically disclosed, the drive assembly 237 includes a drive motor 2371 and a transmission housing 2372. The drive motor 2371 is fixedly installed at the bottom of the movable housing 231. The end of the transmission housing 2372 is fixedly connected to the front of the movable housing 231. A splined shaft 2373 is provided inside the transmission housing 2372. A collar 2374 is fixedly sleeved on the outside of the splined shaft 2373. A positioning ring 2375 is rotatably provided on the outer ring of the collar 2374. The positioning ring 2375 is slidably disposed on the inner wall of the transmission housing 2372. A sleeve 2376 is movably sleeved on the outside of the splined shaft 2373. A belt drive component 2377 is provided between the output shaft of the drive motor 2371 and the end of the sleeve 2376.

[0040] Furthermore, the end of the take-up roller 234 is provided with a spline groove 2341, and the end of the spline shaft 2373 away from the sleeve 2376 is inserted into the spline groove 2341, and the opening of the spline groove 2341 and the end of the spline shaft 2373 are both rounded.

[0041] When the absorbent cloth 235 is exhausted or needs cleaning, loosen the pin on the slide rail 238, pull out the movable housing 231 along the slide rail 238, open the cover plate 2361 of the fixing component 236, pull the movable block 2378 outward, compress the elastic telescopic rod 2379, and drive the positioning ring 2375 to slide on the inner wall of the transmission housing 2372. Then, under the action of the collar 2374, the spline shaft 2373 moves into the sleeve 2376 until the spline shaft 2373 disengages from the spline groove 2341 at the end of the take-up roller 234, and the unwind roller 233 and the take-up roller 234 can be taken out.

[0042] Furthermore, a movable groove is provided on the outer side of the transmission housing 2372, and a movable block 2378 is fixedly connected to the positioning ring 2375. The movable block 2378 extends outward through the movable groove, and an elastic telescopic rod 2379 is provided between the end of the movable block 2378 and the outer side of the transmission housing 2372. The elastic telescopic rod 2379 has a built-in resettable elastic element. The belt drive component 2377 consists of two pulleys and a drive belt. The two pulleys are respectively sleeved on the output shaft of the drive motor 2371 and the end of the sleeve 2376, and the drive belt is sleeved between the two pulleys.

[0043] The drive motor 2371 drives the take-up roller 234 to rotate, automatically replacing the saturated adsorption material and avoiding the problem of traditional fixed adsorption materials failing due to excessive humidity.

[0044] The spline groove 2341 and spline shaft 2373 are designed to be connected, which allows the winding roller 234 to be installed and removed. The spline groove 2341 and spline shaft 2373 at the end of the winding roller 234 are rounded to achieve tool-free quick connection and simplify the maintenance process.

[0045] Furthermore, a slide rail 238 is fixedly connected to the bottom of the equipment box 12, and a slide bar 239 is slidably arranged on the inner wall of the slide rail 238. The slide bar 239 is fixedly installed on the outside of the movable box 231, and an insertable pin is provided on the outside of the slide rail 238. The position of the slide bar 239 and the movable box 231 can be fixed by using the pin.

[0046] The movable housing 231 is connected to the equipment housing 12 via a slide rail 238 and is quickly fixed with a pin, facilitating regular cleaning or replacement of the moisture-absorbing cloth 235. The outer casing 11 and the equipment housing 12 are designed separately, allowing for independent maintenance of internal components and reducing overall maintenance costs.

[0047] Workflow: S1, Air intake and primary condensation dehumidification Outside air enters through the air inlet 111 of the outer casing 11, is filtered by the filter screen 113, and is then drawn into the equipment housing 12 by the intake fan assembly 22. The air first flows through the heat exchange tube 213 area of ​​the first dehumidification assembly 21. The refrigerant circulating inside the heat exchange tube 213 is temperature-controlled by the liquid collector 212, lowering the air temperature below the dew point. Water vapor in the air condenses into liquid water on the surface of the heat dissipation fins 215, flows along the V-shaped plate 2151 to the condensate collection frame 216, and is finally discharged outside the housing through the drain pipe.

[0048] S2, Secondary Adsorption Dehumidification and Air Purification After initial dehumidification, the air enters the second dehumidification component 23 and flows through the moisture-absorbing fabric 235. The fabric surface adsorbs residual water molecules and intercepts fine particulate matter, further purifying the air.

[0049] When the moisture absorption fabric 235 reaches the threshold humidity, the drive component 237 is started. The drive motor 2371 drives the sleeve 2376 to rotate through the belt drive component 2377. The sleeve 2376 drives the spline shaft 2373 to rotate, which in turn drives the take-up roller 234 to rotate, thereby taking up the saturated fabric and releasing the dry fabric at the same time.

[0050] S3, Dry Air Circulation and Emission After double dehumidification, the dry air enters the interior through the vent of the equipment box 12, maintaining the humidity of the component's operating environment below the safe threshold. The hot and humid air inside the equipment box 12 is discharged through the exhaust unit 3 and then discharged through the exhaust port 112 on the top of the outer casing 11, forming a complete airflow cycle.

[0051] S4. Maintenance and Consumable Replacement When the absorbent cloth 235 is exhausted or needs cleaning, loosen the pin on the slide rail 238, pull out the movable housing 231 along the slide rail 238, open the cover plate 2361 of the fixing component 236, pull the movable block 2378 outward, compress the elastic telescopic rod 2379, and drive the positioning ring 2375 to slide on the inner wall of the transmission housing 2372. Then, under the action of the collar 2374, the spline shaft 2373 moves into the sleeve 2376 until the spline shaft 2373 disengages from the spline groove 2341 at the end of the take-up roller 234. Then the unwind roller 233 and the take-up roller 234 can be taken out, replaced with new cloth, and reinstalled. The whole process does not require disassembling the internal components of the equipment box 12.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
