Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, specifically to a ring network box with dehumidification function. Background Technology

[0002] A ring main unit (RMU) is an enclosure used to house a ring main unit. RMUs are typically installed outdoors, and are susceptible to increased humidity due to weather and environmental factors. High humidity levels can cause condensation on the inner walls and electrical components, reducing the insulation strength of switches, disconnectors, and terminal blocks, leading to flashover and equipment malfunctions such as accidental closing or tripping of switches. Therefore, dehumidification devices need to be installed inside the RMU to control the humidity.

[0003] Existing dehumidifiers typically include an air inlet and an air outlet. They dehumidify the air by drawing it in from the chamber and then expelling the dry air back into the chamber through the outlet. The fixed airflow path of a single air inlet concentrates the dehumidification area near the device, resulting in poor dehumidification performance further away from it. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ring network box with dehumidification function in response to the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A ring network box with dehumidification function includes a box body and a dehumidification unit. The dehumidification unit includes a shell, an evaporator, a condenser, a compressor, and a fan. The shell is disposed on the side wall of the box body. The evaporator, condenser, compressor, and fan are all disposed inside the shell. The input end of the condenser is connected to the output end of the compressor. The output end of the condenser is connected to the input end of the evaporator through a capillary tube. The output end of the evaporator is connected to the input end of the compressor. A base is disposed at the bottom of the box body. A U-shaped air inlet channel is disposed inside the base. Multiple air inlets connected to the air inlet channel are opened on the base. The air inlet channel is connected to the shell. An air outlet connected to the inside of the box body is disposed on the shell. The fan is used to drive airflow through the evaporator.

[0006] Furthermore, the base is provided with a connecting pipe, the two ends of which are respectively connected to the middle of the air intake channel and the bottom of the housing.

[0007] Furthermore, a drain hopper is provided inside the housing, located below the condenser and evaporator, and a drain pipe is provided at the bottom of the drain hopper, with the other end of the drain pipe extending to the outside of the housing.

[0008] Furthermore, a first one-way valve is provided inside the air inlet. The first one-way valve includes a first fixed seat, a first baffle, and an elastic element. The first fixed seat is disposed inside the air inlet. A first opening is provided in the middle of the first fixed seat. A plurality of first baffles are rotatably disposed inside the first opening. An elastic element is provided on the rotating shaft of the first baffle. The first baffles are distributed in the horizontal direction. The first baffle can rotate horizontally downward to open the first opening when the fan is started; the elastic element can drive the first baffle to rotate horizontally to close the first opening when the fan is turned off.

[0009] Furthermore, a second one-way valve is provided in the air outlet. The second one-way valve includes a second fixed seat and a second baffle. The second fixed seat is disposed on the side wall of the housing. The second fixed seat has a vertically penetrating second opening. Multiple second baffles are rotatably disposed in the second opening. The second baffles are distributed along the vertical direction. The second baffle can rotate vertically to open the second opening when the fan is started; the second baffle can also rotate vertically under the action of gravity to close the second opening when the fan is turned off.

[0010] Furthermore, a grid plate is provided inside the base.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This application improves the base of the ring network box by setting an airflow channel on the base and opening multiple air inlets on the base that communicate with the airflow channel to draw air from multiple locations inside the box, ensuring that air in all areas participates in airflow and dehumidification, thereby improving dehumidification efficiency.

[0017] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, a ring mesh box with dehumidification function includes a box body 1 and a dehumidification unit 2. The box body 1 is a rectangular hollow body. The top of the box body 1 is provided with an umbrella-shaped box top, the bottom of the box body 1 is provided with a base 3, and at least one side wall of the box body 1 is provided with a box door. The base 3 is provided with a grid plate 33, which is used to enhance the support performance of the base 3 and divide the internal space of the base 3 into a "U"-shaped air intake channel 31. The top of the base 3 is provided with multiple air intake ports 32 that communicate with the air intake channel 31, and the air intake ports 32 are distributed along the edge of the base 3. The dehumidification unit 2 includes a housing 21, an evaporator 22, a condenser 23, a compressor 24, and a fan 25. The housing 21 is located on the side wall of the housing 1. The evaporator 22, condenser 23, compressor 24, and fan 25 are all located inside the housing 21. The input end of the condenser 23 is connected to the output end of the compressor 24. The output end of the condenser 23 is connected to the input end of the evaporator 22 through a capillary tube 26. The output end of the evaporator 22 is connected to the input end of the compressor 24. The air inlet channel 31 communicates with the housing 21. The housing 21 is provided with an air outlet 211 that communicates with the inside of the housing 1. The fan 25 is used to drive the airflow through the evaporator 22.

[0018] Preferably, a connecting pipe 4 is provided on the base 3, with both ends of the connecting pipe 4 connected to the middle of the air inlet channel 31 and the bottom of the housing 21, respectively; a drain hopper 212 is provided inside the housing 21, located below the condenser 23 and the evaporator 22, and a drain pipe 213 is provided at the bottom of the drain hopper 212, with the other end of the drain pipe 213 extending to the outside of the housing 1. To improve the heat exchange effect, several heat exchange fins (not shown in the figure) are provided on the outside of the evaporator 22 and the condenser 23.

[0019] Specifically, such as Figure 2 and Figure 3 As shown, when the fan 25 starts, the air inside the housing 1 enters the intake channel 31 through multiple air inlets 32, and then enters the connecting pipe 4 through the intake channel 31, and then enters the interior of the housing 1 through the connecting pipe 4. The airflow inside the housing 1 passes sequentially through the evaporator 22 and the condenser 23 (e.g., Figure 3 (As shown by arrow B in the image), as air passes through evaporator 22, it is pre-cooled and condenses into water, which flows downwards along evaporator 22 and eventually drips into drain hopper 212 (as shown in the image). Figure 3 (As shown by arrow C in the middle), the air is discharged to the outside of the box 1 through the drain pipe 213, while the dry air is discharged into the box 1 through the air outlet 211.

[0020] like Figure 6 and Figure 7 As shown, a first one-way valve 5 is provided inside the air inlet 32. The first one-way valve 5 includes a first fixed seat 51, a first baffle 52, and an elastic element 53. The first fixed seat 51 is installed inside the air inlet 32. A first opening 511 is provided on the first fixed seat 51. The first opening 511 vertically penetrates the first fixed seat 51 to connect the inside of the housing 1 and the air inlet channel 31. Multiple first baffles 52 are rotatably arranged inside the first opening 511. The first baffles 52 are distributed in the horizontal direction. The elastic element 53 is a torsion spring. The elastic element 53 is arranged on the rotating shaft of the first baffle 52, and the two ends of the elastic element 53 abut against the first baffle 52 and the first fixed seat 51, respectively. When the fan 25 is off, the elastic element 53 provides a spring force to rotate the first baffle 52 upward, so that the first baffle 52 abuts against the first fixed seat 51 to close the first opening 511; when the fan 25 is started, a negative pressure is formed in the air intake channel 31, and the air in the housing 1 pushes the first baffle 52 downward, so that the first baffle 52 rotates downward to open the first opening 511, and the elastic element 53 deforms to accumulate elastic potential energy.

[0021] like Figure 4 and Figure 5 As shown, a second one-way valve 6 is provided in the air outlet 211. The second one-way valve 6 includes a second fixed seat 61 and a second baffle 62. The second fixed seat 61 is installed in the air outlet 211. A second opening 611 is provided on the second fixed seat 61. The second opening 611 horizontally penetrates the second fixed seat 61 to connect the inside of the box 1 and the inside of the shell 21. A plurality of second baffles 62 are rotatably arranged in the second opening 611. The second baffles 62 are distributed in the vertical direction. When the fan 25 is off, the second baffle 62 can remain vertical under the action of gravity to close the second opening 611; when the fan 25 is on, the fan 25 pushes the airflow toward the air outlet 211, and the air pushes the second baffle 62 to rotate vertically to open the second opening 611.

[0022] The first one-way valve 5 and the second one-way valve 6 are configured to open the air inlet 32 ​​and the air outlet 211 when the dehumidification unit 2 is working, and to close the air inlet 32 ​​and the air outlet 211 when the dehumidification unit 2 is closed, so as to block the moisture in the air inlet channel 31.

[0023] Specifically, a humidity sensor is installed inside the cabinet 1 to detect the humidity inside the cabinet 1. When the humidity exceeds the preset value, the dehumidification unit 2 starts to work.
