Description

Technical Field

[0001] This application relates to the field of power transmission and distribution equipment technology, and in particular to an intelligent cable branch box. Background Technology

[0002] In power systems, cable distribution boxes, as important electrical equipment, play a crucial role in distributing electrical energy and connecting cables. With the continuous growth of electricity demand and the increasing sophistication of power grid construction, cable distribution boxes have been widely used in urban and rural distribution networks. Cable distribution boxes can branch a single power source into multiple power sources to meet the electricity needs of different users and equipment, greatly improving the flexibility and reliability of power distribution. They are widely used in urban power grids, industrial plants, residential areas, and other locations, providing strong support for ensuring a stable power supply.

[0003] However, existing cable distribution boxes face severe moisture-proof challenges during actual operation, especially in humid environments or extreme weather conditions. Since cable distribution boxes are typically installed outdoors and exposed to the natural environment for extended periods, they are highly susceptible to corrosion from rain, moisture, and condensation. When the insulation material becomes damp, its insulation performance significantly deteriorates. Under operating voltage or overvoltage, insulation breakdown accidents can easily occur, leading to short circuits, tripping, and even fires, seriously threatening the safe and stable operation of the power grid and the safety of people and property. Summary of the Invention

[0004] In order to improve the moisture resistance of cable branch boxes, reduce the moisture absorption of insulation materials, and enhance the safety of power grid operation, this application provides an intelligent cable branch box.

[0005] The intelligent cable branch box provided in this application adopts the following technical solution: A smart cable distribution box includes a box body and a top cover installed on the top of the box body. A limiting plate is fixedly connected to the top side wall of the box body. A dehumidification cavity is formed between the upper part of the limiting plate and the inner wall of the top of the box body. A cable mounting cavity is formed between the lower part of the limiting plate and the inner wall of the box body. A support frame is provided in the dehumidification cavity. A conveyor belt is rotatably mounted on the support frame. Two sets of humidity regulating plates are detachably connected to the conveyor belt. The two sets of humidity regulating plates are symmetrically arranged. The humidity regulating plates protrude from the conveyor belt. Activated carbon is placed inside the humidity regulating plates. The dehumidification chamber is equipped with a drive assembly for moving the support frame and a replacement assembly for rotating the conveyor belt. The top cover is equipped with an openable and closable opening device. The limiting plate has a through hole, and the conveyor belt abuts against the limiting plate, so that the humidity regulating plate on one side of the conveyor belt passes through the through hole and connects to the cable installation cavity; the box is also equipped with a control system for monitoring humidity and controlling the replacement, dehydration and other operations of the humidity regulating plate.

[0006] By adopting the above technical solution, an independent dehumidification chamber is constructed at the top of the cable branch box, and a limiting plate is used to physically separate the dehumidification area from the cable installation area, effectively optimizing the spatial layout and airflow organization within the box. Utilizing a drive assembly to move the support frame and a replacement assembly to drive the conveyor belt, the automated cyclic replacement of two symmetrically arranged activated carbon dehumidification plates is achieved. When the activated carbon on one side becomes saturated, it can be conveyed out, while the dried activated carbon on the other side is conveyed to the working position. This solves the problem of traditional activated carbon dehumidification requiring frequent manual replacement and being unable to operate continuously, significantly improving the efficiency and continuity of moisture-proof maintenance. Furthermore, the conveyor belt's contact with the limiting plate and the through-hole design allow the humidity-regulating plate to extend directly into the cable installation cavity, shortening the dehumidification path and improving the dehumidification response speed around the core electrical components inside the box. Combined with the top-opening device and intelligent control system, it not only facilitates centralized dehydration, regeneration, or replacement of saturated activated carbon, but also allows for precise control of the dehumidification process based on real-time humidity monitoring data. This achieves intelligent and automated moisture-proof management of the cable branch box, effectively preventing the degradation of insulation performance caused by condensation or dampness, and ensuring the safe and stable operation of power equipment.

[0007] Preferably, the humidity regulating plate is made of a flexible material, and the activated carbon particles inside are arranged in multiple independent compartments.

[0008] By adopting the above technical solutions, the flexibility of the humidity regulating plate and the multi-compartment design of activated carbon significantly improve the structural adaptability, mass transfer efficiency, and overall operational stability of the dehumidification components. Firstly, the flexibility of the humidity regulating plate allows it to perfectly adapt to the arc-shaped transmission paths at both ends of the conveyor belt, effectively dispersing mechanical stress during replacement and cyclic operation. This prevents breakage or fatigue damage caused by rigid structures during bending, thus significantly extending the service life of the humidity regulating plate and ensuring smooth and stable transmission. Secondly, dividing the activated carbon into multiple independent compartments breaks the limitations of traditional large-block stacking, greatly increasing the effective contact area between the activated carbon and the humid air inside the chamber, shortening the path of moisture diffusion into the adsorption material, and thus significantly improving the moisture absorption reaction rate and dehumidification efficiency. Simultaneously, the compartmentalized design effectively limits and fixes the activated carbon particles inside, preventing dust from falling due to mutual friction during long-term equipment vibration or conveyor belt movement, thus avoiding dust contamination of precision electrical components inside the cable installation cavity.

[0009] Preferably, the drive assembly includes a lead screw, a first motor, and a guide rod. The support frame is threadedly connected to the lead screw and slides on the guide rod. The first motor is fixedly installed on the inner wall of the dehumidification chamber.

[0010] By adopting the above technical solution, the rotational torque of the motor driven by the first motor can be converted into a smooth linear displacement of the support frame along the axial direction, achieving positioning accuracy and repeatability. This ensures that the support frame can accurately stop at the preset work position during cyclic operation, thereby guaranteeing the continuity and reliability of the humidity control plate replacement process. Secondly, the sliding cooperation design between the guide rod and the support frame plays a crucial role in load bearing and guidance. It can effectively bear the weight of the support frame and its components such as the conveyor belt and humidity control plate above it, as well as the radial load generated during operation. It strictly constrains the movement trajectory of the support frame, preventing it from swaying, tilting, or vibrating during lifting or translation, significantly improving the rigidity and operational stability of the entire mechanical transmission system.

[0011] Preferably, the replacement assembly includes a main drive roller, a driven roller, and a second motor. The two ends of the conveyor belt are respectively wound around the main drive roller and the driven roller. Both the main drive roller and the driven roller are rotatably connected to the support frame. The second motor drives the main drive roller to rotate. The control system includes a position sensor, which is installed on the inner wall of the dehumidification chamber. The position sensor is used to detect the position of the conveyor belt.

[0012] By adopting the above technical solution, when it is necessary to replace the humidity control plate, the control system first controls the drive component to move the humidity control plate away from the through hole. The position sensor detects the movement position of the conveyor belt. When there is enough space at both ends of the conveyor belt for the humidity control plate to move, the second motor drives the main drive roller to rotate, which drives the conveyor belt wound around the main and slave drive rollers to run smoothly. This classic belt drive structure not only runs smoothly and has low noise, but also effectively transmits power and swaps the positions of the two humidity control plates.

[0013] Preferably, a sealing ring is fixedly connected to one side wall of the limiting plate near the conveyor belt, the sealing ring is arranged around the through hole, and the conveyor belt abuts against the sealing ring.

[0014] By adopting the above technical solution, a sealing ring is set around the through hole on the side of the limiting plate near the conveyor belt, and it is made to fit tightly against the conveyor belt, thus constructing an efficient physical isolation barrier between the dehumidification chamber and the cable installation chamber. First, this flexible sealing structure can effectively fill the tiny assembly gap between the limiting plate and the conveyor belt, completely blocking the direct airflow between the upper and lower chambers, and preventing moisture from entering the dehumidification chamber through the gaps and affecting the drying humidification plate inside the chamber.

[0015] Preferably, the top opening device includes two sets of opening and closing components. Each opening and closing component includes an opening and closing plate, a first gear, a first rack, a second rack, and a second gear. The two sets of opening and closing components are symmetrically arranged. A connecting hole is provided on the top cover, and a sliding groove is provided inside the top cover. The sliding groove communicates with the connecting hole, and the opening and closing plate is slidably connected to the sliding groove. The first rack is fixedly connected to the side wall of the opening and closing plate, the lead screw passes through and is rotatably connected in the slide groove, the second gear is fixedly sleeved on the lead screw, the second rack slides in the slide groove, the second gear meshes with the second rack, and the second rack meshes with the first gear.

[0016] By adopting the above technical solution, during the vertical movement of the support frame, the lead screw rotates, driving the second gear to rotate. The rotation of the second gear drives the second rack to move. When the second rack meshes with the first gear, the second rack drives the first gear to rotate, and the rotation of the first gear drives the first rack to move. The movement of the first rack drives the opening and closing plate to move, thereby controlling the opening and closing of the connecting hole. The distance between the initial position of the second rack and the first gear is used to adjust the conveyor belt to a suitable position, preventing the inner wall of the through hole from obstructing the movement of the humidity regulating plate, so as to facilitate the replacement operation of the humidity regulating plate.

[0017] Preferably, protrusions are fixedly connected to both sides of the connecting hole on the outer side wall of the top cover, and a cover plate is slidably connected to the protrusion. The cover plate has a triangular cross-section and is magnetically connected to the corresponding opening and closing plate, moving synchronously with the opening and closing plate. A slot and a sealing groove are opened on the side wall of one cover plate, and an insert and a sealing ring are fixedly connected to the other cover plate. The insert is inserted into the slot, and the sealing ring is engaged in the sealing groove.

[0018] By employing the aforementioned technical solution, a magnetic connection is used to link the sliding cover plate on the protrusion with the internal opening and closing plate. This allows the internal transmission mechanism to drive the external cover plate to move synchronously when opening or closing, forming a continuous physical barrier on the top cover surface. This effectively prevents rainwater, sand, and other external debris from directly intruding into the connection holes and internal sliding groove area. Secondly, the two cover plates utilize a structure where slots and inserts, as well as sealing rings and sealing grooves, interlock to create a tight leak-proof barrier, ensuring the top cover has excellent waterproof, dustproof, and airtight properties. Furthermore, the well-fitted interlocking mechanism greatly enhances the mechanical interlocking strength and positional stability at the joints of adjacent cover plates, preventing gaps caused by misalignment due to long-term outdoor vibration or wind.

[0019] Preferably, an adhesive sheet A is fixedly disposed on the surface of the conveyor belt, and an adhesive sheet B matching the adhesive sheet A is fixedly disposed on the bottom surface of the humidity regulating plate. The adhesive sheet A and the adhesive sheet B are attached to each other to achieve detachable fixation.

[0020] By adopting the above technical solution and using a detachable structure, the humidity regulating plate can be easily installed and replaced.

[0021] Preferably, the control system includes a humidity sensor, a pressure sensor, and a weather detection device. The humidity sensor is fixedly installed inside the cable mounting cavity to monitor the ambient humidity in real time. The pressure sensor is installed inside the humidity regulating plate to detect the weight change of activated carbon after absorbing water. The weather detection device is installed on the outside of the housing to acquire external meteorological data in real time. The control system is electrically connected to the first motor and the second motor respectively, and drives each motor to perform corresponding actions based on multi-source sensor data.

[0022] By adopting the above technical solution and constructing a multi-dimensional intelligent control network integrating internal environmental monitoring, material status sensing, and external weather early warning, precise and automated closed-loop control of the dehumidification components is achieved. Firstly, a humidity sensor installed in the cable installation cavity serves as the core feedback node, capturing minute humidity fluctuations within the chamber around the clock, providing real-time decision-making basis for the control system. Secondly, a pressure sensor is integrated into the humidity regulating plate, cleverly utilizing the physical property of activated carbon increasing in mass after adsorbing moisture to achieve non-destructive online monitoring of the dehumidification material saturation. When the detected weight reaches a preset threshold or the cable installation cavity remains in a high humidity state for an extended period, the control system automatically instructs the second motor to start the conveyor belt for cyclical replacement of the activated carbon plate. This completely eliminates the inefficient mode of traditional equipment relying on manual timed maintenance or blind replacement based on experience, greatly improving operational efficiency and extending the lifespan of consumables. Furthermore, the introduction of a weather detection device installed on the outside of the chamber gives the system proactive environmental adaptability. For example, when impending rainfall or extreme weather is detected, the system can intervene in advance with the first motor to close the top cover opening and closing component, preventing rainwater from flowing back into the chamber. When sunny weather is detected, the system uses the first motor to open the top cover opening and closing assembly and pushes the humidity regulating plate out of the connection hole, using direct sunlight to dehydrate the activated carbon and improve the recycling of the activated carbon.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By constructing an independent dehumidification chamber at the top of the cable branch box and physically separating the dehumidification area from the cable installation area with a limiting plate, the spatial layout and airflow organization within the box are effectively optimized. Utilizing a drive assembly to move the support frame and a replacement assembly to drive the conveyor belt, the system achieves automated cyclic replacement of two symmetrically arranged activated carbon dehumidification plates. When the activated carbon on one side becomes saturated, it can be conveyed out, while the dried activated carbon on the other side is conveyed to the working position. This solves the problem of traditional activated carbon dehumidification requiring frequent manual replacement and being unable to operate continuously, significantly improving the efficiency and continuity of moisture-proof maintenance. Furthermore, the design of the conveyor belt abutting the limiting plate and passing through the holes allows the humidity regulating plate to extend directly into the cable installation cavity, shortening the dehumidification path and improving the dehumidification response speed around the core electrical components inside the box. Combined with the top opening device and intelligent control system, it not only facilitates centralized dehydration, regeneration, or replacement of saturated activated carbon, but also allows for precise control of the dehumidification process based on real-time humidity monitoring data. This achieves intelligent and automated moisture-proof management of the cable branch box, effectively preventing the degradation of insulation performance caused by condensation or dampness, and ensuring the safe and stable operation of power equipment. The flexible design of the humidity regulating plate and the multi-compartment configuration of activated carbon significantly improve the structural adaptability, mass transfer efficiency, and overall operational stability of the dehumidification assembly. Firstly, the flexible design of the humidity regulating plate allows it to perfectly adapt to the curved transmission paths at both ends of the conveyor belt, effectively dispersing mechanical stress during replacement and cyclic operation. This prevents breakage or fatigue damage caused by rigid structures during bending, thus significantly extending the service life of the humidity regulating plate and ensuring smooth and stable transmission. Secondly, dividing the activated carbon into multiple independent compartments breaks the limitations of traditional large-block stacking, greatly increasing the effective contact area between the activated carbon and the humid air inside the chamber, shortening the path of moisture diffusion into the adsorption material, and thus significantly improving the moisture absorption reaction rate and dehumidification efficiency. Simultaneously, the compartmentalized design effectively limits and fixes the activated carbon particles inside, preventing dust from falling due to mutual friction during long-term equipment vibration or conveyor belt movement, thus avoiding dust contamination of precision electrical components inside the cable installation cavity. During the vertical movement of the support frame, the lead screw rotates, driving the second gear to rotate. The rotation of the second gear drives the second rack to move. When the second rack meshes with the first gear, the second rack drives the first gear to rotate, which in turn drives the first rack to move. The movement of the first rack moves the opening and closing plate, thereby controlling the opening and closing of the connecting hole. The distance between the initial position of the second rack and the first gear is used to adjust the conveyor belt to a suitable position, preventing the inner wall of the through hole from obstructing the movement of the humidity regulating plate, thus facilitating the replacement of the humidity regulating plate.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses an intelligent cable branch box, such as... Figure 1 and Figure 2 As shown, the overall structure consists of a housing 1 and a top cover 2, with the top cover 2 fixedly mounted on the top of the housing 1. A limiting plate 3 is provided on the side wall of the top of the housing 1. The four sides of the limiting plate 3 are fixedly welded to the inner wall of the housing 1. The limiting plate 3 and the inner wall of the top of the housing 1 enclose an independent dehumidification chamber 4. The space below the limiting plate 3 serves as a cable installation chamber 5 for installing cables, thus physically separating the dehumidification area from the cable installation area.

[0033] like Figure 2 and Figure 3 As shown, and in combination Figure 4As shown, the dehumidification chamber 4 is equipped with a support frame 6, on which a circulating conveyor belt 7 is mounted. Two sets of humidity-regulating plates 8 are detachably mounted on the conveyor belt 7. The conveyor belt 7 and the humidity-regulating plates 8 are detachably connected. An adhesive plate A is fixed to the surface of the conveyor belt 7, and an adhesive plate B is fixed to the bottom surface of the humidity-regulating plate 8. The humidity-regulating plates 8 are quickly installed and removed by adsorption through the adhesion of the two adhesive plates, facilitating later maintenance and replacement. The two sets of humidity-regulating plates 8 are symmetrically arranged along the horizontal line and protrude from the surface of the conveyor belt 7. The humidity-regulating plates 8 are filled with activated carbon as a moisture-absorbing material. The dehumidification chamber 4 is also equipped with a drive component 9 that drives the support frame 6 to move, and a replacement component 10 that drives the conveyor belt 7 to rotate and switch the humidity-regulating plates 8. The top cover 2 is equipped with an automatic opening and closing device. The chamber 1 also integrates a control system for real-time monitoring of humidity data inside the chamber and automatic control of a series of operations such as replacement of the humidity-regulating plates 8 and dehydration and regeneration of activated carbon based on the monitoring results.

[0034] like Figure 3 As shown, the humidity regulating plate 8 is made of a flexible material with bending properties. The activated carbon inside is arranged in multiple independent compartments. The bending structure can adapt to the arc-shaped transmission path of the conveyor belt 7, avoiding stress concentration and damage during the cyclic rotation. The compartment setting not only increases the contact area between the activated carbon and the humid air, improving the moisture absorption efficiency, but also limits and fixes the activated carbon, preventing the activated carbon particles from shaking randomly in the regulating plate or even accumulating on one side, and preventing dust from being scattered and generated when the equipment is vibrating during operation, thus avoiding contamination of the electrical components in the cable installation cavity 5.

[0035] like Figure 2 As shown, the upward protrusion in the middle of the limiting plate 3 is thicker than other parts, while the recessed area is used to install the drive assembly 9 and to reserve space for the movement of the support frame 6. A through hole 12 is provided vertically in the middle of this protrusion, allowing the humidity-regulating plate 8 on one side of the conveyor belt 7 to pass through the through hole 12 and contact the cable mounting cavity 5, directly dehumidifying the core area. To ensure the sealing of the dehumidification cavity 4 and the cable mounting cavity 5, a sealing ring 20 is fixed to the surface of the protrusion on the limiting plate 3. The sealing ring 20 surrounds the through hole 12, and the conveyor belt 7 always abuts against the sealing ring 20, filling the gap between the limiting plate 3 and the conveyor belt 7, blocking the airflow between the two cavities, and preventing moisture from entering the dehumidification cavity 4 and affecting the storage state of the drying humidity-regulating plate 8. Under normal circumstances, the humidity regulating plate 8 on one side is inserted through the through hole 12 and is located at the top of the cable installation cavity 5. When the humidity inside the cable installation cavity 5 is high, the activated carbon inside the humidity regulating plate 8 dehumidifies. When the humidity is not high but the temperature inside the chamber is high, the activated carbon partially dehydrates and absorbs heat at high temperatures, thus achieving a certain heat dissipation and cooling effect. Therefore, when the humidity is not consistently high, the activated carbon inside one humidity regulating plate 8 can be recycled without the need for frequent manual inspection and replacement.

[0036] like Figure 2 and Figure 3 As shown, there are two sets of drive components 9, located diagonally opposite each other on the support frame 6. Each drive component 9 consists of a lead screw 13, a first motor 14, and a guide rod 15. Both the lead screw 13 and the guide rod 15 are vertically oriented. The first motor 14 is mounted on the limiting plate 3, and the bottom end of the lead screw 13 is fixedly connected to it. The guide rod 15 is fixedly connected to the limiting plate 3. The support frame 6 is threadedly connected to the lead screw 13 and slidably connected to the guide rod 15. Alternatively, the guide rod 15 can be replaced with the lead screw 13, resulting in four corners connected to the lead screw 13 and driven synchronously. During operation, the first motor 14 drives the lead screw 13 to rotate, converting the rotational motion into linear movement of the support frame 6 along the guide rod 15. This allows for precise adjustment of the support frame 6's position, ensuring the humidity regulating plate 8 can accurately move to its corresponding position and providing stable displacement support for changing the humidity regulating plate 8. Compared to a single drive component 9, two sets of drive components 9 provide more driving force, and their symmetrical arrangement makes the movement of the support frame 6 more stable and precise.

[0037] like Figure 2 and Figure 5 As shown, the replacement component 10 includes a main drive roller 16, a driven roller 17, and a second motor 18. The two ends of the conveyor belt 7 are respectively wrapped around the main drive roller 16 and the driven roller 17. The main and driven rollers 17 are rotatably mounted on the support frame 6. The output end of the second motor 18 is connected to the main drive roller 16 to provide power. The second motor 18 is mounted on the support frame 6. The control system integrates a humidity sensor, a pressure sensor, a position sensor 19, and a weather detection device. The humidity sensor is installed inside the cable mounting cavity 5 to monitor the internal ambient humidity in real time. The pressure sensor is located inside the humidification plate 8 and determines the saturation level of the activated carbon by detecting the weight change after the activated carbon absorbs moisture. The position sensor 19 is installed on the inner wall of the dehumidification chamber 4 to detect the position status of the conveyor belt 7 in real time. When the humidification plate 8 needs to be replaced, the drive assembly 9 first moves the support frame 6 to disengage the humidification plate 8 from the through hole 12. After the position sensor 19 confirms that the conveyor belt 7 has moved to the appropriate position, the second motor 18 starts to drive the main drive roller 16 to rotate, driving the conveyor belt 7 to run smoothly and completing the exchange of positions between the two sets of humidification plates 8. This realizes the automatic switching between the humidification plates 8 in the moisture-saturated and dry states. The humidification plate 8, driven by the drive assembly 9, extends into the through hole 12 after drying.

[0038] A weather monitoring device is installed on the outside of the housing 1 to collect real-time meteorological information such as rainfall and sunlight. The control system is electrically connected to the first motor 14 and the second motor 18, respectively, and realizes intelligent control based on multi-dimensional sensor data: when the humidity in the cable installation cavity 5 is too high or the activated carbon in the humidity regulating plate 8 reaches saturation weight, the replacement component 10 is automatically activated to switch the humidity regulating plate 8; when the weather monitoring device predicts severe weather such as rainfall, it controls the drive component 9 and the opening and closing component 11 to close the connection hole 26 to prevent rainwater backflow; when the outside weather is sunny, the connection hole 26 is opened, and the humidity regulating plate 8 extends out of the top cover 2, using direct sunlight to dehydrate and regenerate the activated carbon, realizing the recycling of moisture-absorbing materials. The entire process requires no manual intervention, realizing intelligent moisture-proof and dehumidification management of the cable branch box.

[0039] like Figure 5 and Figure 6 As shown, the opening device on the top cover 2 includes two sets of diagonally arranged opening and closing components 11. Each set of opening and closing components 11 consists of an opening and closing plate 21, a first gear 22, a first rack 23, a second rack 24, and a second gear 25. A connecting hole 26 is provided in the middle of the top cover 2 along the vertical direction, allowing the humidity regulating plate 8 to communicate with the outside. A sliding groove 27 is provided on the inner wall of the connecting hole 26. The opening and closing plate 21 is slidably assembled in the sliding groove 27. The two opening and closing plates 21 move relative to each other or away from each other in the sliding groove 27 to control the opening and closing state of the connecting hole 26. The first rack 23 is fixed to the side wall of the opening and closing plate 21. The lead screw 13 passes through the sliding groove 27 and is rotatably connected to the wall of the sliding groove 27. The second gear 25 is fixedly sleeved on the lead screw 13. The second rack 24 is slidably disposed in the sliding groove 27 and meshes with the second gear 25. The second rack 24 also meshes with the first gear 22. When the connecting hole 26 is closed, the second rack 24 and the first gear 22 are not meshed and are a certain distance apart. When the support frame 6 moves with the lead screw 13, the lead screw 13 drives the second gear 25 to rotate, driving the second rack 24 to slide towards the first gear 22. When the second rack 24 and the first gear 22 are about to mesh and transmit power, the support frame 6, carrying the humidity regulating plate 8, is a certain height away from the through hole 12 and disengages from the through hole 12. At this time, if only the humidity regulating plate 8 needs to be replaced, the first motor 14 stops and the second motor 18 starts. After the humidity regulating plate 8 is replaced, if the weather detection device detects that the outside weather is sunny and suitable for dehydrating activated carbon, the first motor 14 does not stop, the lead screw 13 continues to rotate, the second rack 24 meshes and transmits power to the first gear 22, and the rotation of the first gear 22 drives the opening and closing plate 21 to open through the first rack 23. At the same time, the humidity regulating plate 8 that needs to be dehydrated is transported to the connecting hole 26, so that the humidity regulating plate 8 passes through the connecting hole 26 and faces the sunlight, thus enhancing the dehydration effect. Conversely, when the lead screw 13 drives the support frame 6 to gradually move down, the opening and closing plate 21 closes along with it, thereby realizing the automatic opening and closing of the connection hole 26. The opening and closing action is linked with the displacement of the support frame 6, ensuring that the connection hole 26 opens synchronously when the humidity regulating plate 8 is replaced or when dehydrating, and remains closed and sealed during daily operation.

[0040] like Figure 5 and Figure 7 As shown, the outer wall of the top cover 2 has protrusions 28 on both sides of the connecting hole 26. A cover plate 29 is slidably mounted on the protrusion 28. The cover plate 29 and the corresponding opening and closing plate 21 are linked by magnetic adsorption. One of the cover plates 29 has a slot 31 and a sealing groove 30 on its side wall. The other cover plate 29 has a corresponding insert 32 and a sealing ring 33. When the two cover plates 29 are closed, the insert 32 is inserted into the slot 31 and the sealing ring 33 is engaged in the sealing groove 30, forming a tight sealing structure that effectively prevents rainwater, sand and dust and other external impurities from entering the interior of the box 1.

[0041] The implementation principle of this application embodiment is as follows: by constructing an independent dehumidification chamber 4 on the top of the housing 1, and using a limiting plate 3 to physically separate the dehumidification area from the cable installation area, functional zoning and airflow isolation are achieved. The control system uses humidity sensors, pressure sensors, and weather detection devices as multi-source information inputs to sense the humidity status in the cable installation chamber 5, the water saturation of the activated carbon in the humidification plate 8, and external weather changes in real time. When the system determines that dehumidification is required, the first motor 14 drives the lead screw 13 to rotate, driving the support frame 6 to move along the guide rod 15 to the preset work position. At the same time, the gear and rack linkage mechanism controls the sliding of the opening and closing plate 21 to open or close the connection hole 26 of the top cover 2. The second motor 18 drives the conveyor belt 7 to run, and uses the feedback signal of the position sensor 19 to accurately control the stop position of the conveyor belt 7, so that the two sets of symmetrically arranged humidification plates 8 can exchange positions—moving the saturated humidification plate 8 out of the work position, and at the same time conveying the dry humidification plate 8 into the cable installation chamber 5 for continued dehumidification. The design of the humidity regulating plate 8 passing through the through hole 12 on the limiting plate 3 shortens the dehumidification path, allowing the activated carbon to directly act on the humid air inside the cable installation cavity 5. The double sealing structure of the sealing ring 20 and the shield 29 ensures effective isolation between the two cavities and between the box 1 and the outside environment. In sunny weather, the system can automatically open the top cover 2, exposing the humidity regulating plate 8 to sunlight for dehydration and regeneration, realizing the recycling of activated carbon, thereby achieving intelligent and automated closed-loop control of moisture-proof management of the cable branch box.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
