Description

Technical Field

[0001] This invention relates to the field of ring network box technology, and in particular to a ring network box with an anti-condensation structure. Background Technology

[0002] A ring main unit, also known as a ring main unit or ring main switchgear, is a key piece of equipment in an urban power grid distribution system. Its core function is to receive, distribute, and control electrical energy in a ring-shaped distribution network to improve the reliability and flexibility of power supply, and is an important guarantee for achieving continuous and stable power supply.

[0003] Ring mains enclosures commonly use heaters to prevent condensation. By raising the temperature inside the enclosure, the dew point is lower than the surface of the equipment to avoid condensation. However, the enclosure is difficult to seal completely, and a breathing effect occurs due to the temperature difference between day and night. During the day, when heated, the internal air pressure increases and hot and humid air is expelled. At night, when cooling and contraction occur, a negative pressure is formed, continuously drawing in high-humidity air from the outside through the gaps. In this process, the heater actually exacerbates the temperature fluctuation inside the enclosure, making the breathing effect more significant and introducing more moisture. Simply heating leads to a vicious cycle of constantly dealing with the inhaled moisture, which is not only difficult to effectively suppress condensation, but also results in high energy consumption. Summary of the Invention

[0004] This invention discloses a ring mesh box with an anti-condensation structure, aiming to solve the technical problem that the box body is difficult to completely seal, and will produce a breathing effect under the temperature difference between day and night. During the day, when heated, the internal air pressure increases and hot and humid air is discharged. At night, when it cools and contracts, a negative pressure is formed, and high-humidity air from the outside is continuously drawn in through the gaps. During this process, the heater aggravates the temperature fluctuation inside the box, making the breathing effect more significant and introducing more moisture. Simply heating leads to a vicious cycle of constantly dealing with the inhaled moisture, which is neither effective in inhibiting condensation nor in reducing energy consumption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ring mesh box with an anti-condensation structure includes a box body, a base on the bottom inner wall of the box body, a heat conduction mechanism on the top outer wall of the base, and a drive mechanism and a regeneration dehumidification mechanism. The regeneration dehumidification mechanism includes a drying chamber and a partition plate. A first dehumidification port and a second dehumidification port are provided on the top outer wall of the drying chamber. The interior of the drying chamber is divided into a drying chamber and a regeneration chamber by the partition plate. A movable plate is also provided inside the drying chamber. A heating cylinder is provided between the movable plate and the partition plate. A support frame and at least one installation chamber are provided inside the heating cylinder. Several adsorption ports are provided on the wall of the installation chamber. Multiple equidistant limiting plates are provided inside the installation chamber. Desiccant is filled between two adjacent limiting plates. A heating port corresponding to the installation chamber is provided on the support frame. An installation cavity is formed inside the support frame. A heating wire is provided in the installation cavity. The heating port is connected to the installation cavity. An installation opening is provided on the bottom inner wall of the drying chamber.

[0006] The above technical solution enables the recycling of desiccant, reduces usage costs and maintenance workload, improves the economy and convenience of ring network box operation, and effectively prevents condensation inside the box. Specifically, when the pressure inside the box increases (during the day / heating), the internal hot air expands, and the pressure is greater than that outside. Under the operation of the drive mechanism, this pressure causes the partition plate and the moving plate to be in their initial positions, separating the drying chamber into a drying chamber and a regeneration chamber. The drying chamber is connected to the inside of the box through the first vent, and its internal installation chamber is filled with dry desiccant. The regeneration chamber is in a closed and isolated state, and its corresponding second vent is completely covered and sealed by the baffle on the partition plate. Then, the hot and humid air inside the box is discharged into the drying chamber of the drying chamber under the action of pressure difference. During the air discharge process, the desiccant filled in the installation chamber adsorbs the moisture inside the box through several adsorption ports opened on its chamber wall, thereby reducing the humidity inside the box and preventing condensation. When the pressure inside the chamber decreases (at night / during cooling), the internal air cools and contracts, resulting in a lower pressure than the outside. Humid air from outside is first drawn into the drying chamber, where moisture is captured by the desiccant before entering the chamber. Only dry air enters the chamber. When the system determines from the humidity sensor signal that the desiccant in the drying chamber is approaching saturation, the drive mechanism activates, pushing or pulling the moving plate and partition plate to slide within the drying chamber. This partition plate completely isolates the first exhaust port and the installation port from the interior of the chamber, transforming the original drying chamber into a regeneration chamber. The second exhaust port is opened, and the heating wire operates in the installation chamber, generating heat. This heat is transferred to the installation chamber through the heating port, heating the desiccant. Driven by a motor, the heating cylinder rotates slowly, ensuring uniform heating of the desiccant and improving regeneration efficiency and speed. The heating wire, once energized, causes the moisture in the desiccant to evaporate. The high-temperature, high-humidity air, under the pressure difference, is discharged from the chamber through the newly connected second exhaust port, achieving desiccant regeneration. After regeneration, with the assistance of the drive mechanism, the desiccant returns to the drying chamber to continue drying.

[0007] In a preferred embodiment, the drive mechanism is located on one side of the regeneration and dehumidification mechanism. The drive mechanism includes an electric telescopic rod and a mounting frame. Both the electric telescopic rod and the mounting frame are fixedly installed above the heat conduction mechanism. The movable end of the electric telescopic rod is fixedly connected to a slide rod and a connecting assembly. The slide rod has several teeth. A gear is connected to the mounting frame via a bearing. The gear meshes with the teeth. A limiting frame is provided on one outer wall of the mounting frame. A slider is slidably connected to the limiting frame. A limiting rod is hinged to one outer wall of the slider. A limiting block is provided at the eccentric position of the gear. The end of the limiting rod away from the slider is hinged to the limiting block. A push rod is provided on one outer wall of the slider. A connecting frame is fixedly connected to one outer wall of the push rod. A push plate is provided on the connecting frame. The push plate passes through the drying chamber and is fixedly connected to the partition plate.

[0008] This technical solution enables the control system to issue commands based on the humidity sensor signal, activating the electric telescopic rod. Its movable end precisely extends and retracts linearly, directly pushing the slide rod in a vertical linear motion. The teeth on the slide rod mesh with the gear mounted on the mounting frame, converting the linear motion of the slide rod into the precise rotational motion of the gear. As the gear rotates, the limiting block rotates around the center of the gear. The limiting block transmits this circular motion to the slider via a limiting rod hinged to it. Because the slider is confined within the limiting frame, it performs reciprocating linear motion. The slider then transmits power to the partition plate fixed to the push plate via a push rod, connecting frame, and push plate. When the electric telescopic rod extends or retracts according to the program, the aforementioned linkage ultimately drives the partition plate and moving plate to slide within the drying chamber, thus achieving the interchangeability of the drying chamber and regeneration chamber functions.

[0009] In a preferred embodiment, the heat-conducting mechanism includes several equally spaced heat-conducting plates and a heat-absorbing shell. The heat-absorbing shell is installed on the top outer wall of the heat-conducting plates. Inside the heat-absorbing shell, there are several equally spaced air-guiding pipes and a sealing plate. Several corrugated expansion joints are fixedly installed on the bottom inner wall of the heat-absorbing shell. The corrugated expansion joints are sleeved on the outer wall of the air-guiding pipes. A connecting rod is fixedly connected to the top of the corrugated expansion joint. A sealing block is fixedly connected to one end of the connecting rod. The end of the connecting rod away from the sealing block is inserted into the interior of the air-guiding pipe. Several equally spaced connection ports are opened on the top outer wall of the sealing plate. A sealing ring is provided on the inner wall of the connection port. The sealing block and the connection port are sealed and connected by the sealing ring.

[0010] This technical solution utilizes several equidistantly distributed heat-conducting plates to quickly absorb heat from the air surrounding electrical components and conduct it to the top-mounted heat-absorbing shell. The heat-absorbing shell further collects and concentrates this heat, causing the internal temperature to rise. As the temperature inside the heat-absorbing shell increases, the air in the vent pipe expands due to heat, pushing the corrugated expansion joint to extend. The extension of the corrugated expansion joint causes the connecting rod to move. One end of the connecting rod is inserted into the vent pipe, and the other end is connected to the sealing block, causing the sealing block to move upward. The electric telescopic rod can extend or retract based on signals from temperature and humidity sensors that detect environmental parameters inside the enclosure. When the electric telescopic rod extends or retracts, it drives the sealing block to move through the connecting assembly, thereby changing the sealing state between the sealing block and the connection port on the top outer wall of the sealing plate. When the sealing block is sealed to the connection port, the airflow channel between the vent pipe and the outside is blocked. When the sealing block leaves the connection port, the connection port opens, and the vent pipe connects to the outside, allowing airflow to flow between the vent pipe and the outside.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 A ring network box with an anti-condensation structure includes a box body 1, a base 2 on the bottom inner wall of the box body 1, and a heat conduction mechanism on the top outer wall of the base 2. It also includes a drive mechanism and a regeneration dehumidification mechanism. The regeneration dehumidification mechanism includes a drying chamber 20 and a partition plate 22. The top outer wall of the drying chamber 20 has a first dehumidification port 5 and a second dehumidification port 6. The interior of the drying chamber 20 is divided into a drying chamber and a regeneration chamber by the partition plate 22. A movable plate is also provided inside the drying chamber 20, and a heating cylinder 2 is disposed between the movable plate and the partition plate 22. 3. The heating cylinder 23 is provided with a support frame 26 and at least one installation chamber 27. The walls of the installation chamber 27 are provided with several adsorption ports. The interior of the installation chamber 27 is provided with multiple equally spaced limiting plates 30. The space between two adjacent limiting plates 30 is filled with desiccant 31. The support frame 26 is provided with heating ports 28 corresponding to the installation chamber 27. The support frame 26 is provided with an installation cavity. The installation cavity is provided with a heating wire 29. The heating port 28 is connected to the installation cavity. The bottom inner wall of the drying chamber 20 is provided with an installation port 19.

[0026] It should be noted that a humidity sensor and a temperature sensor are integrated on the mounting port 19. This configuration allows for direct and rapid sensing of the temperature and humidity of the air entering the drying chamber from inside the chamber 1 through the mounting port 19. When the humidity inside the chamber 1 rises and humid air enters the drying chamber, the humidity sensor can detect the change in humidity in a timely manner, and the temperature sensor can monitor the temperature of the air entering the drying chamber. Thus, the system can accurately control the drive mechanism and adjust the working state of the heating cylinder 23.

[0027] The drying chamber 20 has sliding grooves on both inner walls, and limit rings 24 are slidably connected to the sliding grooves. The limit rings 24 are engaged with the outer circumferential wall of the heating cylinder 23. The sliding connection structure between the limit rings 24 and the sliding grooves can provide certain support and constraints for the heating cylinder 23, reduce the shaking of the heating cylinder 23 during rotation, and make the rotation of the heating cylinder 23 more stable and smooth, thereby improving the stability and reliability of the entire regeneration and dehumidification mechanism.

[0028] In the specific implementation process, a baffle 25 is fixedly connected to one side of the outer wall of the partition plate 22. The baffle 25 is slidably connected to the top inner wall of the drying chamber 20, and the baffle 25 can completely cover the second exhaust port 6. During normal moisture absorption, the regeneration chamber is strictly sealed, that is, the baffle 25 tightly covers the second exhaust port 6, and together with the partition plate 22, forms a closed regeneration chamber, which effectively prevents airflow short circuit and ensures that all moisture to be treated is guided to the drying chamber, thereby improving dehumidification efficiency.

[0029] The moving plate has a motor 32 on one side of its outer wall. The output shaft of the motor 32 passes through the moving plate and is fixedly connected to the heating cylinder 23. The motor 32 drives the heating cylinder 23 to rotate, causing the desiccant 31 inside the cylinder to be slightly agitated and disturbed, which helps to break the water vapor and make it diffuse into the airflow more quickly and be carried away.

[0030] Specifically, when the pressure inside the chamber 1 increases (during the day / when heated), the internal hot air expands and the pressure is greater than that outside. Under the operation of the drive mechanism, this pressure causes the partition plate 22 and the moving plate to be in their initial positions, separating the drying chamber 20 into a drying chamber and a regeneration chamber. The drying chamber is connected to the inside of the chamber 1 through the first exhaust port 5. The installation chamber 27 inside the drying chamber is filled with a dry desiccant 31. The regeneration chamber is in a closed and isolated state. Its corresponding second exhaust port 6 is completely covered and sealed by the baffle 25 on the partition plate 22. Then, the hot and humid air inside the chamber 1 is discharged into the drying chamber of the drying chamber 20 under the action of pressure difference. During the air discharge process, the desiccant 31 filled in the installation chamber 27 adsorbs the moisture inside the chamber 1 through several adsorption ports opened on its chamber wall, thereby reducing the humidity inside the chamber 1 and preventing condensation. When the pressure inside chamber 1 decreases (at night / during cooling), the internal air cools and contracts, resulting in a lower pressure than the outside. Humid air from outside is first drawn into the drying chamber 20. The moisture in the humid air is captured by the desiccant 31 before entering chamber 1, ensuring only dry air enters. When the system determines from the humidity sensor signal that the desiccant 31 in the drying chamber is approaching saturation, the drive mechanism activates, pushing or pulling the moving plate and partition plate 22 to slide within the drying chamber 20. This partition plate 22 completely isolates the first exhaust port 5 and the mounting port 19 from the interior of chamber 1, transforming the original drying chamber into a regeneration chamber. The second exhaust port 6 is opened, and the heating wire 29 operates within the mounting chamber, generating heat. This heat is transferred through the heating port 28. The desiccant 31 is heated in the installation chamber 27. The heating cylinder 23 is driven by the motor 32 to rotate slowly, ensuring that the desiccant 31 is heated evenly and improving the regeneration efficiency and speed. The heating wire 29 heats up after being energized, causing the moisture in the desiccant 31 to evaporate. The high temperature and high humidity air is discharged from the box 1 through the newly connected second exhaust port 6 under the action of pressure difference, realizing the regeneration of the desiccant 31. After regeneration, the desiccant 31 returns to the drying chamber position to continue the drying work with the assistance of the drive mechanism. This device can realize the recycling of the desiccant 31, reduce the use cost, reduce the maintenance workload, improve the economy and convenience of the ring network box operation, and effectively prevent condensation in the box 1.

[0031] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the drive mechanism is located on one side of the regeneration and dehumidification mechanism. The drive mechanism includes an electric telescopic rod 13 and a mounting frame. Both the electric telescopic rod 13 and the mounting frame are fixedly installed above the heat conduction mechanism. The movable end of the electric telescopic rod 13 is fixedly connected to a slide rod 7 and a connecting assembly. The slide rod 7 has several teeth. The mounting frame is connected to a gear 14 via a bearing. The gear 14 meshes with the teeth. A limiting frame 16 is provided on one outer wall of the mounting frame. A slider is slidably connected to the limiting frame 16. A limiting rod 15 is hinged to one outer wall of the slider. A limiting block is provided at the eccentric position of the gear 14. The end of the limiting rod 15 away from the slider is hinged to the limiting block. A push rod 17 is provided on one outer wall of the slider. A connecting frame 18 is fixedly connected to one outer wall of the push rod 17. A push plate 21 is provided on the connecting frame 18. The push plate 21 penetrates the drying chamber 20 and is fixedly connected to the partition plate 22.

[0032] The push plate 21 and the partition plate 22 are arranged perpendicularly to each other.

[0033] Specifically, based on the signal from the humidity sensor, the control system issues a command to activate the electric telescopic rod 13, whose movable end performs precise linear extension and retraction. The movable end of the electric telescopic rod 13 directly pushes the slide rod 7 to perform vertical linear motion. The teeth on the slide rod 7 mesh with the gear 14 mounted on the mounting frame, thereby converting the linear motion of the slide rod 7 into the precise rotational motion of the gear 14. When the gear 14 rotates, the limiting block will perform circular motion around the center of the gear 14. The limiting block transmits the circular motion to the slider through the limiting rod 15 hinged to it. Since the slider is restricted within the limiting frame 16, the slider performs reciprocating linear motion. Then, the slider transmits power to the partition plate 22 fixedly connected to the push plate 21 through the push rod 17, connecting frame 18 and push plate 21 fixed to it. When the electric telescopic rod 13 extends or retracts according to the program, through the above linkage, the partition plate 22 and the moving plate are finally driven to slide in the drying chamber 20, thereby realizing the interchangeability of the functions of the drying chamber and the regeneration chamber.

[0034] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the heat conduction mechanism includes several heat conduction plates 3 evenly distributed and a heat absorption shell 4. The heat absorption shell 4 is installed on the top outer wall of the heat conduction plates 3. The heat absorption shell 4 is provided with several air guide pipes 8 evenly distributed and a sealing plate 10 inside. Several corrugated expansion joints 9 are fixedly installed on the bottom inner wall of the heat absorption shell 4. The corrugated expansion joints 9 are sleeved on the outer wall of the air guide pipes 8. A connecting rod 11 is fixedly connected to the top of the corrugated expansion joint 9. A sealing block 12 is fixedly connected to one end of the connecting rod 11. The end of the connecting rod 11 away from the sealing block 12 is inserted into the interior of the air guide pipe 8. Several connection ports are opened on the top outer wall of the sealing plate 10 evenly distributed. A sealing ring is provided on the inner wall of the connection port. The sealing block 12 and the connection port are sealed and connected by the sealing ring.

[0035] The electric telescopic rod 13 is fixedly installed on the top outer wall of the sealing plate 10. The connecting assembly includes several fixed rods. One end of the fixed rod is fixedly connected to the top outer wall of the sealing block 12. A movable rod is fixedly connected to the top of the fixed rod away from the sealing block 12. One end of the movable rod is fixedly connected to the movable end of the electric telescopic rod 13. The fixed rod and movable rod in the connecting assembly accurately transmit the power of the electric telescopic rod 13 to the sealing block 12, ensuring that the telescopic movement of the electric telescopic rod 13 can accurately control the movement of the sealing block 12, making the control of the entire system more precise and reliable, and reducing the risk of system failure due to transmission component failure.

[0036] In the specific implementation process, the top outer wall of the heat absorption shell 4 is provided with an air outlet, which corresponds to and is connected to the installation port 19.

[0037] Specifically, several equidistant heat-conducting plates 3 can quickly absorb heat from the air surrounding the electrical components and conduct the heat to the top-mounted heat-absorbing shell 4. The heat-absorbing shell 4 further collects and concentrates this heat, causing the internal temperature of the heat-absorbing shell 4 to rise. When the internal temperature of the heat-absorbing shell 4 rises, the air in the air duct 8 expands due to heat, pushing the corrugated expansion joint 9 to extend. The extension of the corrugated expansion joint 9 drives the connecting rod 11 to move. One end of the connecting rod 11 is inserted into the air duct 8, and the other end is connected to the sealing block 12, thereby causing the sealing block 12 to move upward. The telescopic rod 13 can extend or retract based on signals received from the temperature and humidity sensors that detect environmental parameters inside the enclosure 1. When the electric telescopic rod 13 extends or retracts, it will drive the sealing block 12 to move through the connecting component, thereby changing the sealing state between the sealing block 12 and the connection port opened on the top outer wall of the sealing plate 10. When the sealing block 12 is sealed to the connection port, the air duct 8 is blocked from the external airflow channel. When the sealing block 12 leaves the connection port, the connection port opens, the air duct 8 is connected to the outside, and the airflow can flow between the air duct 8 and the outside.

[0038] Reference Figure 1 , Figure 7 , Figure 11 and Figure 12 In a preferred embodiment, both the inner walls of the first exhaust port 5 and the second exhaust port 6 are equipped with filter screens and hydrophobic microporous membranes, which can effectively filter dust, impurities, and moisture in the air entering and exiting the ring main unit. The filter screen can block larger dust and debris particles, preventing them from entering the ring main unit and contaminating the electrical components. The hydrophobic microporous membrane can prevent moisture from passing through, further preventing external humid air from entering the unit, while allowing normal air circulation. This ensures the anti-condensation effect, improves the protection level of the ring main unit, and extends the service life of the electrical components.

[0039] Working principle: When the pressure inside chamber 1 increases (during the day / when heated), the internal hot air expands, and the pressure becomes greater than the external pressure. This pressure, under the operation of the drive mechanism, causes the partition plate 22 and the moving plate to be in their initial positions, separating the drying chamber 20 into a drying chamber and a regeneration chamber. The drying chamber is connected to the inside of chamber 1 through the first exhaust port 5, and its internal installation chamber 27 is filled with a desiccant 31. The regeneration chamber is in a closed and isolated state, and its corresponding second exhaust port 6 is completely covered and sealed by the baffle 25 on the partition plate 22. The humid air inside the rear chamber 1 is discharged into the drying chamber of the drying chamber 20 under the action of pressure difference. During the air discharge process, the desiccant 31 filled in the installation chamber 27 adsorbs the moisture inside the chamber 1 through several adsorption ports opened on its chamber wall, thereby reducing the humidity inside the chamber 1 and preventing condensation. When the pressure inside the chamber 1 decreases (at night / during cooling), the internal air cools and contracts, and the pressure is less than that outside. The external humid air will be drawn into the drying chamber 20 first. The moisture in the humid air is absorbed by the desiccant 31 before entering the chamber 1. 1. The system captures the desiccant 31 in the drying chamber, allowing only dry air to enter. When the system determines that the desiccant 31 in the drying chamber is approaching saturation based on the humidity sensor signal, the drive mechanism is activated, pushing or pulling the moving plate and the partition plate 22 to slide within the drying chamber 20. This uses the partition plate 22 to completely isolate the first exhaust port 5 and the mounting port 19 from the interior of the chamber, transforming the original drying chamber into a regeneration chamber. The second exhaust port 6 is opened, and the heating wire 29 operates in the mounting chamber, generating heat. The heat is transferred to the mounting chamber 27 through the heating port 28 to heat the desiccant 31. The heating cylinder 23, driven by the motor 32, rotates slowly to ensure uniform heating of the desiccant 31, improving regeneration efficiency and speed. After the heating wire 29 is energized, it heats up, causing the moisture in the desiccant 31 to evaporate. The high-temperature, high-humidity air is discharged from the chamber 1 through the newly connected second exhaust port 6 under the action of pressure difference, realizing the regeneration of the desiccant 31. After regeneration, with the assistance of the drive mechanism, the desiccant 31 returns to the drying chamber to continue drying.
