Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to a cable branch box integrating an ambient temperature and humidity sensing module. Background Technology

[0002] Cable distribution boxes are crucial electrical devices in power distribution systems used for cable branching and transfer, widely used in urban power grids, industrial parks, residential communities, and other scenarios. Their core function is to distribute the power from a main cable to multiple branch cables, or to transfer cables of different cross-sections and specifications, enabling line expansion without cutting the main cable, significantly simplifying the power distribution network installation process. These devices typically feature waterproof, dustproof, and impact-resistant designs, and are available in outdoor and indoor models to suit various applications, adapting to complex working environments. They are key components ensuring the stable operation of power distribution systems.

[0003] During operation, cable distribution boxes generate Joule heat when current flows through conductors, and internal components such as switches and connectors also release heat during operation. If this heat cannot be dissipated in time, the internal temperature will continue to rise, affecting the insulation performance and lifespan of electrical components. To solve this problem, most cable distribution boxes are equipped with cooling fans. Driven by the fan, cool external air is rapidly introduced into the distribution box, allowing the cool air to fully contact and exchange heat with the high-temperature components and air inside the box. The air carrying heat is then exhausted through the pre-designed ventilation holes in the box, forming a continuous air circulation that effectively removes heat from the box and maintains the internal temperature within a safe range.

[0004] When the ambient humidity of the branch box is high, the air entering the box after being accelerated by the cooling fan is highly humid. Under temperature changes, moisture easily condenses on the surfaces of metal parts and insulating components inside the box, forming water droplets. This not only reduces the insulation performance of the insulating components, increasing the risk of leakage and short circuits, but also causes corrosion of metal structural parts and conductor joints, exacerbating wear and poor contact problems. Prolonged exposure to high humidity will lead to the accumulation of moisture and corrosion, which may, in severe cases, cause line faults and affect the reliability of the entire power distribution system. Summary of the Invention

[0005] The purpose of this application is to address the problem mentioned in the background art that when the branch box is in a high-humidity environment, humid air enters the interior of the branch box under the action of the cooling fan, which will affect the normal use of the branch box over time. This application provides a cable branch box with an integrated environmental temperature and humidity sensing module.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A cable distribution box integrating an ambient temperature and humidity sensing module includes a distribution box body, a mounting base fixed to the lower end of the distribution box body, a shield fixed to the upper end of the distribution box body, a cooling fan fixed to the upper end of the distribution box body, the air outlet of the cooling fan extending into the interior of the distribution box body, a dustproof net fixed to the upper end of the cooling fan, multiple protective doors installed inside the distribution box body, a control panel installed on one of the protective doors, ventilation holes opened on the side of the distribution box body, a temperature sensor fixed inside the distribution box body, the temperature sensor being electrically connected to the control panel, and a dehumidification structure for absorbing moisture from the air provided inside the distribution box body.

[0008] By adopting the above technical solution, the cooling fan operates during the use of the branch box to dissipate heat from the interior of the branch box, ensuring its normal operation. A temperature sensor monitors the internal temperature of the branch box in real time, and alerts operators when the temperature is abnormal, in conjunction with the control panel. During heat dissipation, outside air is drawn into the branch box by the cooling fan and then passes through a dehumidification structure. This dehumidification structure absorbs moisture from the air, preventing corrosion of internal electronic components due to excessive humidity, which could affect the normal operation of the branch box.

[0009] Furthermore, the dehumidification structure includes a corrugated hose fixed to the air outlet of the cooling fan, a dehumidification box fixed to the lower end of the corrugated hose, an installation ring fixed to the lower end of the dehumidification box, a placement box fixed to the upper end of the installation ring, the placement box slidingly extending into the dehumidification box, ventilation meshes fixed to the upper end of the dehumidification box and the lower end of the placement box, the interior of the placement box for placing dehumidifying particles, a shaking component provided between the branch box body and the dehumidification box, and a flow guiding component provided inside the branch box body.

[0010] By adopting the above technical solution, external air is accelerated into the dehumidification box under the action of the cooling fan. The dehumidification particles can adsorb the moisture in the air, thereby effectively reducing the amount of moisture entering the branch box and reducing the impact of moisture on the normal use of the branch box.

[0011] Furthermore, the shaking assembly includes a drive motor fixed to the side of the branch box body, the drive motor being electrically connected to the control panel, the output end of the drive motor extending into the interior of the branch box body and having a drive shaft fixed thereon, a cam fixed to the end of the drive shaft away from the drive motor, a first mounting block fixed to the surface of the dehumidification box, a roller rotatably connected inside the first mounting block, the surface of the cam being in contact with the surface of the roller, and a support member provided between the dehumidification box and the branch box body.

[0012] By adopting the above technical solution, when dehumidifying, the drive motor is turned on, which drives the drive shaft to rotate, so that the cam can rotate and squeeze the roller. Together with the support frame, it can shake the dehumidification box, so that the dehumidification particles can be turned up and down, allowing the dehumidification particles to fully contact the air and improve the dehumidification effect.

[0013] Furthermore, the support includes a second mounting block fixed to the surface of the dehumidification box. The upper ends of the first and second mounting blocks are both fixed with support columns. The upper end of the support column is fixed with a return spring. A support sleeve is slidably sleeved on the support column. The upper end of the support sleeve is fixedly connected to the branch box body. The end of the return spring away from the support column is fixedly connected to the support sleeve.

[0014] By adopting the above technical solution, when the cam squeezes the roller, the support column slides along the inner wall of the support sleeve, and the return spring is continuously compressed and rebounded, thereby playing the role of support and reset.

[0015] Furthermore, a humidity sensor is fixed inside the branch box body, and the humidity sensor is electrically connected to the control panel.

[0016] By adopting the above technical solution, the humidity sensor is used to monitor the humidity inside the branch box in real time. When an abnormality occurs, it can be used in conjunction with the control panel to remind the operator to check the condition inside the branch box.

[0017] Furthermore, the flow guiding assembly includes a bidirectional ball screw rotatably connected inside the branch box body. Two symmetrically arranged flow guiding plates are sleeved on the bidirectional ball screw. A nut seat adapted to the bidirectional ball screw is fixed inside the flow guiding plate. The nut seat is sleeved on the bidirectional ball screw. A transmission component is provided between the bidirectional ball screw and the drive shaft.

[0018] By adopting the above technical solution, when the drive shaft rotates, the bidirectional ball screw rotates along with it under the action of the transmission components, thereby enabling the two guide plates to move in opposite directions, and thus guiding the dry air to flow evenly to the various electrical component areas inside the branch box body, further improving the uniformity of dehumidification and heat dissipation.

[0019] Furthermore, the transmission component includes pulleys fixed to the ends of the drive shaft and the bidirectional ball screw, and the two pulleys are connected by a transmission belt.

[0020] By adopting the above technical solution, the transmission plays a transmission role. When the drive shaft rotates, the bidirectional ball screw can rotate along with it under the action of the pulley and the transmission belt.

[0021] Furthermore, two symmetrically arranged guide rods are fixed inside the branch box body, and the guide plate is slidably sleeved on the guide rods.

[0022] By adopting the above technical solution, the guide rod plays a guiding and further supporting role when the deflector moves, so that the deflector can move smoothly.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, during the heat dissipation process, when the cooling fan accelerates external air and sends it into the branch box body, the accelerated air enters the dehumidification box through a corrugated hose, and then enters the placement box, where it comes into contact with the dehumidifying particles. The dehumidifying particles absorb moisture from the air, achieving air drying. The dried air then enters the branch box body, providing a dry working environment for the internal electrical components. This dehumidification structure effectively removes moisture, preventing excessive humidity in the air entering the branch box body, which could cause dampness, corrosion, or other problems for the internal electronic components, thus affecting the normal operation of the entire branch box.

[0025] 2. In this application, during dehumidification, the drive motor is started via the control panel. The drive motor drives the drive shaft to rotate, and the cam at the end of the drive shaft rotates accordingly. The cam surface continuously contacts and compresses the roller surface. In conjunction with the support component, the dehumidification box and the internal placement box are driven to shake up and down, so that the dehumidification particles are fully turned over in the placement box. By turning over the dehumidification particles, the phenomenon of particle clumping can be effectively avoided, thereby affecting the dehumidification effect and ensuring that the contact area between the dehumidification particles and the air is maximized.

[0026] 3. In this application, when the drive shaft rotates, the double-sided ball screw rotates under the action of the pulley and the transmission belt. When the double-sided ball screw rotates, the guide plate moves back and forth in opposite directions under the action of the nut seat and the guide rod, thereby adjusting the position of the two guide plates inside the branch box body, and guiding the dry air to flow evenly to the various electrical component areas inside the branch box body, further improving the uniformity of dehumidification and heat dissipation.

[0027] 4. In this application, the humidity sensor is used to monitor the humidity inside the branch box in real time. When the humidity is abnormal, the abnormality is displayed on the control panel to remind the operator to check the condition inside the branch box and check whether there is external water ingress, so as to ensure the normal use of the branch box.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0036] This application discloses a cable branch box that integrates an environmental temperature and humidity sensing module.

[0037] Reference Figure 1 and Figure 2 A cable distribution box integrating an ambient temperature and humidity sensing module includes a distribution box body 1, a mounting base 11 fixed at the lower end of the distribution box body 1, a shield 12 fixed at the upper end of the distribution box body 1, a cooling fan 13 fixed at the upper end of the distribution box body 1, the air outlet of the cooling fan 13 extending into the interior of the distribution box body 1, a dustproof net fixed at the upper end of the cooling fan 13, multiple protective doors 14 installed inside the distribution box body 1, a control panel 15 installed on one of the protective doors 14, heat dissipation holes 16 opened on the side of the distribution box body 1, a temperature sensor 17 fixed inside the distribution box body 1, the temperature sensor 17 being electrically connected to the control panel 15, and a dehumidification structure for absorbing moisture from the air being provided inside the distribution box body 1.

[0038] When the branch box is in use, the cooling fan 13 operates, accelerating the outside air into the branch box body 1 and then sending it out through the heat dissipation holes 16, thereby carrying away the heat inside the branch box body 1 and achieving heat dissipation. The temperature sensor 17 monitors the internal temperature of the branch box body 1 in real time. When an abnormal temperature is detected, the control panel 15 displays the abnormality, alerting operators to check the internal condition of the branch box body 1 for any abnormal temperature rise, ensuring the normal operation of the branch box. During heat dissipation, outside air is sent into the branch box body 1 by the cooling fan 13 and then passes through a dehumidification structure. The dehumidification structure adsorbs moisture from the air, preventing excessive humidity inside the branch box body 1 from affecting its normal operation.

[0039] Reference Figure 2 - Figure 5 The dehumidification structure includes a corrugated hose 2 fixed to the air outlet of the cooling fan 13. A dehumidification box 21 is fixed to the lower end of the corrugated hose 2. An installation ring 22 is fixed to the lower end of the dehumidification box 21. The installation ring 22 is connected to the dehumidification box 21 by bolts. A placement box 23 is fixed to the upper end of the installation ring 22. The placement box 23 slides into the dehumidification box 21. Ventilation mesh 24 is fixed to both the upper end of the dehumidification box 21 and the lower end of the placement box 23. The placement box 23 is used to place dehumidifying particles. A shaking component is provided between the branch box body 1 and the dehumidification box 21. A flow guiding component is provided inside the branch box body 1.

[0040] The shaking component includes a drive motor 25 fixed to the side of the branch box body 1. The drive motor 25 is electrically connected to the control panel 15. The output end of the drive motor 25 extends into the interior of the branch box body 1 and is fixed with a drive shaft 251. A cam 252 is fixed to the end of the drive shaft 251 away from the drive motor 25. A first mounting block 253 is fixed to the surface of the dehumidification box 21. A roller 254 is rotatably connected inside the first mounting block 253. The surface of the cam 252 is in contact with the surface of the roller 254. A support is provided between the dehumidification box 21 and the branch box body 1.

[0041] In addition, the support includes a second mounting block 255 fixed to the surface of the dehumidification box 21. The upper ends of the first mounting block 253 and the second mounting block 255 are both fixed with support columns 256. The upper end of the support column 256 is fixed with a return spring 257. A support sleeve 258 is slidably sleeved on the support column 256. The upper end of the support sleeve 258 is fixedly connected to the branch box body 1. The end of the return spring 257 away from the support column 256 is fixedly connected to the support sleeve 258.

[0042] During the heat dissipation process, when the cooling fan 13 accelerates the outside air and sends it into the branch box body 1, the accelerated air enters the corrugated hose 2, then through the corrugated hose 2 into the dehumidification box 21. After passing through the ventilation mesh 24 at the top of the dehumidification box 21, it enters the placement box 23, where it comes into contact with the dehumidifying particles. The moisture in the air is absorbed by the dehumidifying particles, achieving air drying. The dried air then enters the branch box body 1 through the ventilation mesh 24 at the bottom of the placement box 23, providing a dry working environment for the internal electrical components. This effectively dehumidifies the air, preventing excessive humidity from entering the branch box body 1, which could cause moisture damage, corrosion, or other issues affecting the normal operation of the entire branch box.

[0043] During dehumidification, the drive motor 25 is started via the control panel 15. The drive motor 25 drives the drive shaft 251 to rotate, and the cam 252 at the end of the drive shaft 251 rotates accordingly. The surface of the cam 252 continuously contacts and compresses the surface of the roller 254, causing the dehumidification box 21 to sway up and down under the action of the support. The support column 256 slides along the inner wall of the support sleeve 258, and the return spring 257 continuously compresses and rebounds, causing the dehumidification box 21 and the internal placement box 23 to sway synchronously. This allows the dehumidification particles to be fully turned over in the placement box 23, preventing the particles from clumping and affecting the dehumidification effect, and ensuring that the contact area between the dehumidification particles and the air is maximized.

[0044] Once the dehumidifying particles are saturated, the protective door 14 can be opened, the bolts used to fix the mounting ring 22 can be removed, and the placement box 23 can be pulled out from the bottom of the dehumidifying box 21 through the mounting ring 22 to replace the new dehumidifying particles. The operation is convenient and efficient, effectively ensuring the stability of the internal environment of the cable branch box.

[0045] Reference Figure 2 and Figure 3 A humidity sensor 3 is fixed inside the branch box body 1, and the humidity sensor 3 is electrically connected to the control panel 15.

[0046] The humidity sensor 3 is used to monitor the humidity inside the branch box body 1 in real time. When the humidity is abnormal, the abnormality is displayed on the control panel 15 to remind the operator to check the condition inside the branch box body 1 and check whether there is external water ingress, so as to ensure the normal use of the branch box.

[0047] Reference Figure 2 , Figure 3 , Figure 5The flow guiding assembly includes a bidirectional ball screw 4 rotatably connected inside the branch box body 1. Two symmetrically arranged flow guiding plates 41 are sleeved on the bidirectional ball screw 4. A nut seat 42 adapted to the bidirectional ball screw 4 is fixed inside the flow guiding plate 41. The nut seat 42 is sleeved on the bidirectional ball screw 4. A transmission component is provided between the bidirectional ball screw 4 and the drive shaft 251.

[0048] The transmission component includes pulleys 43 fixed to the ends of the drive shaft 251 and the bidirectional ball screw 4, and the two pulleys 43 are connected by a transmission belt 431.

[0049] In addition, two symmetrically arranged guide rods 44 are fixed inside the branch box body 1, and the flow guide plate 41 is slidably sleeved on the guide rods 44.

[0050] Meanwhile, when the drive shaft 251 rotates, the pulley 43 at its end rotates with the drive shaft 251. Then, under the action of the transmission belt 431, the pulley 43 at the end of the bidirectional ball screw 4 rotates, thereby driving the bidirectional ball screw 4 to rotate. When the bidirectional ball screw 4 rotates, the two nut seats 42 on it move back and forth in opposite directions under the restriction of the guide rod 44, thereby driving the guide plate 41 to move back and forth in opposite directions, realizing the adjustment of the position of the two guide plates 41 inside the branch box body 1, thereby guiding the dry air to flow evenly to the various electrical component areas inside the branch box body 1, further improving the uniformity of dehumidification and heat dissipation.

[0051] Working Principle: When the branch box is in use, the cooling fan 13 operates, accelerating the external air into the branch box body 1 and then flowing out through the ventilation holes 16, thereby carrying away the heat inside the branch box body 1 and achieving heat dissipation. When the cooling fan 13 accelerates the external air into the branch box body 1, the accelerated air enters the corrugated hose 2, then enters the dehumidification box 21, passes through the ventilation mesh 24 at the top of the dehumidification box 21, and enters the placement box 23, where it comes into contact with the dehumidifying particles. The moisture in the air is absorbed by the dehumidifying particles, achieving air drying. The dried air then enters the branch box body 1 through the ventilation mesh 24 at the bottom of the placement box 23, providing a dry working environment for the internal electrical components. This effectively dehumidifies the air, preventing excessive humidity from entering the branch box body 1, which could cause moisture and corrosion of the electronic components inside the branch box body 1, affecting the normal operation of the entire branch box.

[0052] During dehumidification, the drive motor 25 is started via the control panel 15. The drive motor 25 drives the drive shaft 251 to rotate, and the cam 252 at the end of the drive shaft 251 rotates accordingly. The surface of the cam 252 continuously contacts and compresses the surface of the roller 254, causing the dehumidification box 21 to sway up and down under the action of the support. The support column 256 slides along the inner wall of the support sleeve 258, and the return spring 257 continuously compresses and rebounds, causing the dehumidification box 21 and the internal placement box 23 to sway synchronously. This allows the dehumidification particles to be fully turned over in the placement box 23, preventing the particles from clumping and affecting the dehumidification effect, and ensuring that the contact area between the dehumidification particles and the air is maximized.

[0053] Meanwhile, when the drive shaft 251 rotates, the pulley 43 at its end rotates with the drive shaft 251. Then, under the action of the transmission belt 431, the pulley 43 at the end of the bidirectional ball screw 4 rotates, thereby driving the bidirectional ball screw 4 to rotate. When the bidirectional ball screw 4 rotates, the two nut seats 42 on it move back and forth in opposite directions under the restriction of the guide rod 44, thereby driving the guide plate 41 to move back and forth in opposite directions, realizing the adjustment of the position of the two guide plates 41 inside the branch box body 1, thereby guiding the dry air to flow evenly to the various electrical component areas inside the branch box body 1, further improving the uniformity of dehumidification and heat dissipation.

[0054] Staff can view temperature and humidity data in real time through the control panel 15 on the protective door 14. When the dehumidifying particles are saturated, the protective door 14 can be opened, the bolts used to fix the mounting ring 22 can be removed, and the placement box 23 can be pulled out from the bottom of the dehumidifying box 21 through the mounting ring 22 to replace the new dehumidifying particles. The operation is convenient and efficient, effectively ensuring the stability of the internal environment of the cable branch box.
