Description

Technical Field

[0001] This invention belongs to the field of power distribution technology, and specifically discloses a self-circulating dehumidifying power distribution box with a capillary water guiding structure. Background Technology

[0002] Distribution boxes, as fundamental power distribution and control equipment in power systems, are widely used in residential, industrial, and municipal facilities. They typically integrate various electrical components such as circuit breakers, relays, and control modules. During long-term operation, the humidity environment inside the distribution box is one of the key factors affecting its safety and service life. When the distribution box is in a high-humidity environment (such as during the rainy season, in basements, or in coastal areas) or experiences diurnal temperature fluctuations, condensation or moisture accumulation can easily occur inside the box. If moisture adheres to terminals, circuit boards, or wire connections, it may lead to decreased insulation performance, leakage, short circuits, and even equipment failure or fire accidents.

[0003] To address the aforementioned issues, various moisture-proofing and dehumidification solutions for distribution boxes have been proposed in existing technologies. Common methods include: installing desiccant packets inside the distribution box, using electric heaters to raise the internal temperature to prevent condensation, or creating ventilation holes in the box to enhance air convection. However, these solutions all have certain limitations. Desiccants have limited moisture absorption capacity, require regular replacement, have high maintenance costs, and cannot achieve continuous dehumidification; electric heaters, while reducing condensation, significantly increase energy consumption and may cause localized overheating, affecting component performance; simple natural ventilation, when the external humidity is high, can actually introduce more moisture, exacerbating the internal dampness problem.

[0004] Furthermore, some existing technologies attempt to install water-absorbing materials inside the distribution box and remove moisture through natural evaporation. However, in practical applications, the moisture absorbed by the water-absorbing materials is difficult to transfer quickly and directionally to the outside of the box, easily reaching saturation and causing a rapid decline in dehumidification efficiency. Simultaneously, uneven heat distribution inside the distribution box, and the connection points such as wiring terminals and wire assemblies often generate localized high temperatures due to current flow. If moisture in these areas cannot be guided and removed in a timely manner, it will accelerate oxidation and corrosion, creating safety hazards.

[0005] Therefore, designing a dehumidification structure that can efficiently, continuously, and automatically transfer and discharge moisture (especially moisture in critical wiring areas) from inside the distribution box while preventing external moisture from intruding is a technical problem that urgently needs to be solved by those skilled in the art. This invention addresses the above-mentioned technical deficiencies by providing an improved distribution box with water-guiding and dehumidifying functions. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide a self-circulating dehumidification distribution box with a capillary water guiding structure to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides a self-circulating dehumidifying power distribution box with a capillary water guiding structure, comprising a power distribution box body and a water guiding structure. The water guiding structure includes a dehumidifying component fixed to the upper part of the power distribution box body, and further includes a water-absorbing sheet, a second water-absorbing plate, and a first water-absorbing plate fixed inside the power distribution box body. The second water-absorbing plate and the first water-absorbing plate are both strip-shaped sheet structures, and are fixed to the wiring terminals of the power distribution box body. The water-absorbing sheet is fixed to the air inlet end of the inner wall of the power distribution box body. A water guide rod is connected between the second water absorption plate and the first water absorption plate and the dehumidification component. A water guide column is connected between the water absorption plate and the dehumidification component. The water guide column has the same structure as the water guide rod and is used to transfer the moisture inside the main body of the distribution box to the inside of the dehumidification component. The exhaust end of the dehumidifier is connected to an exhaust structure, which is used to drive the water vapor evaporated by the dehumidifier to the outside, and at the same time drive the outside air through the water absorption plate into the main body of the distribution box.

[0008] As a preferred technical solution, the main body of the distribution box includes a protective shell and a protective cover rotatably connected to the opening end of the protective shell. A control module is fixed inside the protective shell, and a wire assembly is connected to the control module. The second water-absorbing plate and the first water-absorbing plate are fixed at the part of the control module that connects to the wire assembly. A sealing head is fixed at the part of the protective shell that passes through the wire assembly.

[0009] As a preferred technical solution, the water guiding column includes a water guiding pipe and a matrix of water-absorbing filaments penetrating inside the water guiding pipe. A wrapping column is fixed inside the water guiding pipe, which can absorb water. The water-absorbing filaments are fixed inside the water guiding pipe by the wrapping column. A connector is fixed at the lower end of the water-absorbing filaments, and the upper end of the water-absorbing filaments is connected to the dehumidifying element. The connector on the water guiding column is fixed to the water-absorbing sheet.

[0010] As a preferred technical solution, the connector on the water guide rod is fixed to the second water absorption plate and the first water absorption plate. The diameter of the water guide rod is smaller than the diameter of the water guide column, and multiple water guide rods are distributed on the second water absorption plate and the first water absorption plate.

[0011] As a preferred technical solution, the water-absorbing sheet, the first water-absorbing plate, the second water-absorbing plate, the connector, the wrapping column, and the water-absorbing filaments are all made of materials with good water absorption effect. The water guide tube is made of a water-impermeable material. The length of the water-absorbing filaments is greater than the length of the water guide tube, and the upper end of the water-absorbing filaments penetrates the protective shell and is connected to the dehumidifying component.

[0012] As a preferred technical solution, a support mesh plate is fixed to the inner wall of the upper opening of the protective shell, and the dehumidification component includes a fixed shell fixed to the top surface of the support mesh plate. A dehumidification box is sleeved on the fixed shell, and the exhaust end of the dehumidification box is connected to the exhaust structure.

[0013] As a preferred technical solution, the dehumidifier further includes a water collection plate fixed in the lower part of the inner cavity of the fixed shell. A heating ring is fixed on the top surface of the water collection plate, and a heating element is embedded inside the heating ring. Both the water collection plate and the heating element absorb water, and the water collection plate is connected to the water-absorbing filaments.

[0014] As a preferred technical solution, the exhaust structure includes an exhaust pipe connected to the exhaust end of the dehumidification box, a transmission rod rotatably connected inside the exhaust pipe, a fan blade fixed on the transmission rod, a transmission motor fixed inside the exhaust pipe, and the output shaft of the transmission motor fixedly connected to the transmission rod.

[0015] As a preferred technical solution, the exhaust end of the dehumidification box is fixed with a breathable mesh plate, a breathable and water-resistant membrane is fixed on the breathable mesh plate, a heating ring is fixed in the middle of the discharge pipe, the heating ring is connected to an external power source, and the discharge pipe has thermal conductivity.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses water guide rods and water guide columns to directionally transfer the water absorbed by the water absorption plates and the first and second water absorption plates to the water collection plate in the dehumidifier. The water is then evaporated using heating coils and heating plates, so that the water in the water collection plate is continuously discharged and never becomes saturated, thereby achieving a continuous dehumidification effect without the need for manual replacement.

[0017] 2. This invention creates negative pressure inside the dehumidification chamber through an exhaust structure (fan blades, drive motor). On the one hand, it forces the water vapor inside the chamber to be drawn out along the water-guiding structure and discharged to the outside, preventing water vapor from flowing back. On the other hand, it allows outside air to enter the chamber after being filtered by water-absorbing plates, which can absorb moisture from the outside air. Thus, while actively exchanging air, it prevents external moisture from intruding, solving the problem of "the more you ventilate, the more humid it becomes" with traditional ventilation methods.

[0018] 3. The present invention fixes the second water-absorbing plate and the first water-absorbing plate to the part of the control module connecting wire group, directly absorbing the moisture in the area, and using the water guide rod to quickly transfer the moisture along with the heat generated by the control module to the dehumidifier for discharge, realizing simultaneous and directional discharge of heat and moisture, significantly reducing the humidity and temperature of key electrical interfaces, thereby extending the equipment life and improving safety.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution: This invention relates to a self-circulating dehumidifying distribution box with a capillary water guiding structure, comprising a distribution box body and a water guiding structure. The water guiding structure includes a dehumidifying component fixed to the upper part of the distribution box body, and also includes a water-absorbing sheet 3, a second water-absorbing plate 35, and a first water-absorbing plate 34 fixed inside the distribution box body. The second water-absorbing plate 35 and the first water-absorbing plate 34 are both strip-shaped sheet structures. The second water-absorbing plate 35 and the first water-absorbing plate 34 are fixed to the wiring terminals of the distribution box body, and the water-absorbing sheet 3 is fixed to the air inlet end of the inner wall of the distribution box body. A water guide rod 33 is connected between the second water absorption plate 35 and the first water absorption plate 34 and the dehumidification component. A water guide column is connected between the water absorption sheet 3 and the dehumidification component. The water guide column has the same structure as the water guide rod 33 and is used to transfer the moisture inside the main body of the distribution box to the inside of the dehumidification component. The exhaust end of the dehumidifier is connected to an exhaust structure, which is used to drive the water vapor evaporated by the dehumidifier to the outside, and at the same time drive the outside air through the water absorption plate 3 into the interior of the distribution box.

[0024] The main body of the distribution box includes a protective shell 11 and a protective cover 1 rotatably connected to the opening end of the protective shell 11. A control module 12 is fixed inside the protective shell 11. A wire group 14 is connected to the control module 12. A second water-absorbing plate 35 and a first water-absorbing plate 34 are fixed at the part where the control module 12 connects to the wire group 14. The wire group 14 is composed of multiple lines and is used to drive the control module 12 to connect with external lines. A sealing head 13 is fixed at the part of the protective shell 11 that penetrates the wire group 14. The sealing head 13 seals the gap where the wire group 14 penetrates the protective shell 11.

[0025] The water guide column includes a water guide tube 31 and a matrix of water-absorbing filaments 38 penetrating inside the water guide tube 31. A wrapping column 36 is fixed inside the water guide tube 31. The wrapping column 36 can absorb water. The water-absorbing filaments 38 are fixed inside the water guide tube 31 through the wrapping column 36. A connector 37 is fixed at the lower end of the water-absorbing filaments 38. The upper end of the water-absorbing filaments 38 is connected to the dehumidifying element. The connector 37 on the water guide column is fixed to the water-absorbing plate 3.

[0026] The connector 37 on the water guide rod 33 is fixed to the second water absorption plate 35 and the first water absorption plate 34. The diameter of the water guide rod 33 is smaller than the diameter of the water guide column. There are multiple water guide rods 33 distributed on the second water absorption plate 35 and the first water absorption plate 34.

[0027] The water-absorbing sheet 3, the first water-absorbing plate 34, the second water-absorbing plate 35, the connector 37, the wrapping column 36, and the water-absorbing filament 38 are all made of materials with good water absorption effect. The water guide pipe 31 is made of a waterproof material. The length of the water-absorbing filament 38 is greater than the length of the water guide pipe 31. The upper end of the water-absorbing filament 38 passes through the protective shell 11 and connects to the dehumidifying component.

[0028] A support mesh plate 32 is fixed to the inner wall of the upper opening of the protective shell 11. The dehumidification component includes a fixed shell 4 fixed to the top surface of the support mesh plate 32. The fixed shell 4 has a hole, and the inner cavity of the fixed shell 4 is connected to the inner cavity of the water pipe 31 through the hole. A dehumidification box 2 is sleeved on the fixed shell 4, and the exhaust end of the dehumidification box 2 is connected to the exhaust structure.

[0029] The dehumidifier also includes a water collection plate 42 fixed in the lower part of the inner cavity of the fixed shell 4. A heating coil 43 is fixed on the top surface of the water collection plate 42, and a heating element 41 is embedded inside the heating coil 43.

[0030] Both the water collecting plate 42 and the heating element 41 absorb water. The water collecting plate 42 is connected to the water-absorbing filament 38. The heat generated by the heating coil 43 is transferred to the heating element 41. In actual use, the staff will fix the protective shell 11 to the indoor wall in advance, and it is necessary to ensure that the air inlet of the protective shell 11 is not blocked. As the control module 12 continues to work, the heat generated by the control module 12 will cause the water vapor inside the protective shell 11 to evaporate. At this time, the air inside the protective shell 11 will be turbulent, so that the water vapor in the protective shell 11 will be absorbed by the water-absorbing filaments 38, the first water-absorbing plate 34, the second water-absorbing plate 35 and the water-absorbing sheet 3, thereby achieving a dry state inside the protective shell 11. When the water collection plate 42 absorbs a large amount of water vapor, the water vapor on the water collection plate 42 will be absorbed by the heating element 41. Operators can add a humidity sensor inside the dehumidification box 2 according to the actual situation. The humidity sensor can detect the humidity of the heating element 41. When the humidity of the heating element 41 is high, the heating coil 43 will heat the heating element 41. At this time, the water on the heating element 41 will evaporate quickly. As the temperature of the heating element 41 rises, the heat from the heating element 41 will be conducted to the upper part of the water collection plate 42. At this time, the water on the upper part of the water collection plate 42 will also evaporate quickly. When the heating element 41 and the water collection plate... When the water on plate 42 evaporates rapidly, the water in the absorbent filaments 38 will be quickly transferred to the water collection plate 42. As the absorbent filaments 38 continue to transfer water to the water collection plate 42, the water in the absorbent filaments 38 will not reach saturation. At this time, the water in the first absorbent plate 34, the second absorbent plate 35 and the absorbent sheet 3 will be quickly transferred to the absorbent filaments 38 through the connector 37. The connector 37 is made of a material with good water absorption, thereby realizing that the water in the first absorbent plate 34, the second absorbent plate 35 and the absorbent sheet 3 is transferred to the water collection plate 42 through the absorbent filaments 38. The control module 12 shown in this document is an electrical component that works in an existing distribution box. When the control module 12 is working, the temperature inside the protective shell 11 will rise. At this time, the water pipe 31 will absorb the heat inside the protective shell 11. Since the water pipe 31 is sleeved on the outside of the water-absorbing filament 38, when the water pipe 31 heats up, the water vapor evaporated by the water-absorbing filament 38 will be directionally transferred to the water collection plate 42 along the water pipe 31. This can prevent the water vapor evaporated by the water-absorbing filament 38 from flowing back into the protective shell 11, thereby achieving rapid drying of the air inside the protective shell 11.

[0031] Example 2: Please refer to Figures 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the fixed shell 4 drives the water pipe 31 to draw out the humid water vapor inside the protective shell 11, since the first water absorption plate 34 and the second water absorption plate 35 are distributed at the part of the control module 12 connecting the wire group 14, the heat around the control module 12 can be quickly transferred to the inside of the dehumidification box 2 through the water pipe 31, thereby realizing the rapid discharge of heat and humid water vapor around the control module 12.

[0032] The exhaust structure includes an exhaust pipe 21 connected to the exhaust end of the dehumidification box 2. A transmission rod 23 rotates inside the exhaust pipe 21. A fan blade 22 is fixed on the transmission rod 23. A transmission motor 24 is fixed inside the exhaust pipe 21. The output shaft of the transmission motor 24 is fixed to the transmission rod 23. When the heating coil 43 causes the temperature of the heating element 41 to rise, the moisture inside the heating element 41 will evaporate quickly inside the dehumidification box 2. In order to achieve rapid discharge of water vapor inside the dehumidification box 2, the power terminal of the drive motor 24 is connected to an external power source. When the drive motor 24 is working, the output shaft of the drive motor 24 drives the fan blade 22 to work through the drive rod 23. The fan blade 22 can drive the water vapor inside the dehumidification box 2 to be discharged to the outside. When the water vapor inside the dehumidifier 2 is discharged to the outside, the inside of the dehumidifier 2 and the fixed shell 4 are under negative pressure. Since the inner cavity of the fixed shell 4 is connected to the inner cavity of the water pipe 31, the water vapor inside the water pipe 31 will enter the inside of the fixed shell 4. At this time, the suction end of the water pipe 31 will drive the water vapor inside the protective shell 11 to the inside of the connector 37, thereby realizing that the water vapor inside the protective shell 11 is absorbed by the connector 37, thereby increasing the effect of the connector 37 in capturing moisture. When the fixed shell 4 drives the water pipe 31 to draw out the humid water vapor inside the protective shell 11, the inside of the protective shell 11 is in a negative pressure state. At this time, the outside air will pass through the water absorption plate 3 and enter the inside of the protective shell 11. The water absorption plate 3 can absorb the water vapor in the outside air, which can reduce the moisture content of the outside air entering the protective shell 11, thereby keeping the inside of the protective shell 11 in a dry state. When the fixed shell 4 drives the water pipe 31 to draw out the humid moisture inside the protective shell 11, since the first water absorption plate 34 and the second water absorption plate 35 are distributed at the part of the control module 12 connecting wire group 14, the heat around the control module 12 can be quickly transferred to the inside of the dehumidification box 2 through the water pipe 31, thereby realizing the rapid discharge of heat and humid moisture around the control module 12. Example 3: Please refer to Figures 1-8 As shown, based on Embodiment 2, the present invention provides a technical solution. Unlike Embodiment 2, in this embodiment, the fan blade 22 can drive the water vapor inside the dehumidification box 2 to be discharged to the outside. When the fan blade 22 drives the water vapor box to be discharged to the outside, the water vapor can pass through the breathable mesh plate 25, the breathable water-blocking membrane, and the discharge pipe 21 to be discharged. The breathable water-blocking membrane can prevent the water vapor inside the discharge pipe 21 from flowing in the opposite direction, thereby preventing water vapor in the outside air from entering the interior of the dehumidification box 2 through the discharge pipe 21.

[0033] The exhaust end of the dehumidification box 2 is fixed with a breathable mesh plate 25, and a breathable water-resistant membrane is fixed on the breathable mesh plate 25. A heating ring 26 is fixed in the middle of the discharge pipe 21. The heating ring 26 is connected to an external power source, and the discharge pipe 21 conducts heat. In actual use, the output shaft of the drive motor 24 drives the fan blade 22 to work through the transmission rod 23. The fan blade 22 can drive the water vapor inside the dehumidification box 2 to be discharged to the outside. When the fan blade 22 drives the water vapor box to be discharged to the outside, the water vapor can pass through the breathable mesh plate 25, the breathable water-blocking membrane, and the discharge pipe 21 to be discharged. The breathable water-blocking membrane can prevent the water vapor inside the discharge pipe 21 from flowing in the opposite direction, thereby preventing the water vapor in the outside air from entering the interior of the dehumidification box 2 through the discharge pipe 21, and maintaining the directional dehumidification effect of the device. When the fan blades 22 drive the water vapor inside the dehumidification box 2 to be discharged to the outside, the heating ring 26 can heat the discharge pipe 21. At this time, the temperature on the discharge pipe 21 rises, which can quickly evaporate the droplets on the inner wall of the discharge pipe 21, thereby keeping the inner wall of the discharge pipe 21 in a dry state and accelerating the discharge speed of water vapor from the discharge pipe 21. It should be noted that the temperature at which the heating ring 26 heats the discharge pipe 21 should not affect the normal operation of the drive motor 24.

[0034] 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 principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
