Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to an internal dehumidification mechanism of a distribution box for power supply. Background Art

[0002] In power systems, distribution boxes, as crucial equipment for energy distribution and circuit control, are widely used in industries such as industry, construction, and transportation. However, during actual operation, moisture can easily form inside distribution boxes due to temperature fluctuations, large diurnal temperature swings, or high humidity, leading to condensation on the surfaces of equipment within. If this moisture is not promptly removed or controlled, it can lead to a range of safety hazards, including insulation degradation, electrical short circuits, and equipment corrosion, seriously impacting the stability and safety of the power distribution system.

[0003] Currently, a common approach to dehumidifying distribution boxes is to install a heater inside the box. While heaters reduce relative humidity by increasing temperature, this method consumes a lot of energy. Heating only reduces relative humidity by raising the temperature, but doesn't actually remove moisture from the box. Moisture can recondense when the temperature drops. Therefore, a dehumidification mechanism for distribution boxes used in power supply applications is proposed. Summary of the Invention

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] The present application discloses an internal dehumidification mechanism for a power distribution box, comprising a cabinet 1, an outer surface of the cabinet 1 having a mounting slot 2, a box 3 fixedly mounted inside the mounting slot 2, and evenly distributed ventilation holes 6 on both sides of the box 3. A storage box 10 is detachably connected to the bottom of the box 3 by means of mounting bolts 18. A through slot 26 is formed on the bottom surface of the box 3, and a dehumidification mechanism is disposed inside the storage box 10. The dehumidification mechanism can be moved into the interior of the box 3 through the through slot 26.

[0028] It also includes an exhaust mechanism and a separation mechanism. A movable groove 15 is provided on the bottom surface of the box body 3. The separation mechanism is located inside the movable groove 15. The separation mechanism can be moved into the box body 3 and block the ventilation hole 6 on the inlet side of the box body 3. The inlet end of the exhaust mechanism is connected to the box body 3, and the inlet end is located between the separation mechanism and the dehumidification mechanism. The outlet end of the exhaust mechanism is fixedly connected to the cabinet body 1.

[0029] In this embodiment, when the air humidity is normal, the dehumidification mechanism is located inside the storage box 10, and the ventilation holes 6 can realize the air exchange between the inside and outside of the cabinet 1, so that the heat in the cabinet 1 is discharged, thereby achieving the purpose of ventilation and heat dissipation;

[0030] When the air humidity is high, the user moves both the partition mechanism and the dehumidification mechanism into the interior of the box body 3. The partition mechanism blocks the ventilation holes 6 on the inlet side of the box body 3 to prevent the external high-humidity gas from entering the interior of the cabinet body 1 through the ventilation holes 6. In addition, the air extraction mechanism is used to draw the air in the cabinet body 1 so that the air passes through the dehumidification mechanism and then enters the interior of the cabinet body 1, thereby drying the air in the cabinet body 1 and realizing internal circulation of the air.

[0031] Furthermore, the dehumidification mechanism includes a frame plate 17, the top of the frame plate 17 is not closed, and a movable plate 23 is slidably connected to the inside of the frame plate 17. A moisture-absorbing cotton 9 is arranged between the lower surface of the movable plate 23 and the bottom surface of the frame plate 17. Positioning parts are provided on the movable plate 23 and the top of the frame plate 17. When the movable plate 23 moves to the top of the frame plate 17, the positioning parts fix the movable plate 23 and the frame plate 17 relatively. An electric push rod 16 is fixedly connected to the surface of the box body 3, and the telescopic end of the electric push rod 16 is fixedly connected to the movable plate 23.

[0032] Furthermore, the top and bottom of the moisture-absorbing cotton 9 are fixedly connected with an insert plate 19, and the inner bottom surface of the frame plate 17 and the lower surface of the movable plate 23 are provided with a slot 20, the insert plate 19 is plugged into the slot 20, and the frame plate 17 and the movable plate 23 are connected to the insert plate 19 by plug-in connecting bolts 22.

[0033] Furthermore, the positioning member includes baffles 21 fixedly installed on both sides of the top of the frame plate 17, and notches compatible with the baffles 21 are provided on both sides of the upper surface of the movable plate 23. Blocks 25 are fixedly connected to the notches of the movable plate 23, and slots 24 compatible with the block 25 are provided on the lower surface of the baffle 21. The block 25 is thicker at the top and thinner at the bottom.

[0034] Furthermore, the widths of the frame plate 17 and the movable plate 23 are adapted to the upper portion of the storage box 10 , the bottom width of the storage box 10 is greater than the widths of the frame plate 17 and the movable plate 23 , and a drainage hole 11 is provided at the bottom of the storage box 10 .

[0035] In this embodiment, the electric push rod 16 is driven to extend and retract, which can drive the frame plate 17 and the movable plate 23 to move up and down. Specifically, if the frame plate 17 and the movable plate 23 are initially located inside the storage box 10, and the block 25 is not located inside the card slot 24, when dehumidification is required, the electric push rod 16 is driven to retract, and the electric push rod 16 can drive the movable plate 23 to move upward. When the block 25 on the movable plate 23 contacts the baffle 21, the movable plate 23 drives the baffle 21 and the frame plate 17 to move upward synchronously. When the frame plate 17 contacts the top surface of the box body 3, the frame plate 17 is restrained by the box body 3 and stops moving upward, while the movable plate 23 and the block 25 on its surface continue to move upward following the electric push rod 16 until the movable plate 23 contacts the top surface of the box body 3 and the block 25 is inserted into the card slot 24. The block 25 cooperates with the card slot 24 to connect the frame plate 17 with the movable plate 23. The moisture-absorbing cotton 9 between the movable plate 23 and the frame plate 17 is in an unfolded state. The moisture-absorbing cotton 9 can absorb moisture in the passing airflow to dry the air.

[0036] When dehumidification is not needed, the electric push rod 16 is driven to extend, driving the moisture-absorbing cotton 9, the movable plate 23, and the frame plate 17 fixed relatively to the movable plate 23 by the positioning piece to move downward to the inside of the storage box 10. When the frame plate 17 contacts the bottom of the storage box 10, the frame plate 17 no longer moves, and the movable plate 23 continues to move downward under the thrust of the electric push rod 16, and drives the card block 25 on the surface to be removed from the card slot 24. In the process of the movable plate 23 moving downward, the moisture-absorbing cotton 9 is compressed to facilitate the reuse of the moisture-absorbing cotton 9.

[0037] During actual application, after the moisture-absorbing cotton 9 is used repeatedly, the moisture-absorbing effect becomes worse and the moisture-absorbing cotton 9 needs to be replaced. Specifically, the user unscrews the mounting bolts 18, then removes the storage box 10, and then unscrews the connecting bolts 22, pulls out the plug plates 19 on both sides of the moisture-absorbing cotton 9 from the slots 20, removes the moisture-absorbing cotton 9 and the plug plates 19, and then inserts the plug plates 19 on both sides of the new moisture-absorbing cotton 9 into the slots 20, and fixes the plug plates 19 with the connecting bolts 22, then installs the storage box 10, and fixes the storage box 10 with the mounting bolts 18.

[0038] Furthermore, the partition mechanism includes a partition 7, which is slidably inserted into the movable groove 15, and the top of the partition 7 is located in the box body 3 and is fixedly connected to the connecting plate 8, and the connecting plate 8 is located above the movable plate 23. The bottom of the partition 7 is located outside the box body 3 and is fixedly connected to the sleeve plate 14. A connecting rod 12 is slidably inserted into the sleeve plate 14, and the upper end of the connecting rod 12 is fixedly connected to the box body 3. A spring 13 is sleeved on the outer surface of the connecting rod 12, and the upper end of the spring 13 is fixedly connected to the sleeve plate 14. The lower end of the spring 13 is fixedly connected to the lower end of the connecting rod 12.

[0039] Furthermore, when the partition 7 moves toward the interior of the box body 3 , the spring 13 is in a stretched state.

[0040] Furthermore, a groove adapted to the connecting plate 8 is opened at the top of the box body 3, and the connecting plate 8 is staggered with the air inlet end of the connecting pipe 4 to avoid the connecting plate 8 being blocked in the connecting pipe 4. The groove is used to accommodate the connecting plate 8, and when the connecting plate 8 is located inside the groove, the lower surface of the connecting plate 8 is flush with the inner surface of the box body 3, so that the movable plate 23 can fit tightly with the inner surface of the box body 3.

[0041] In this embodiment, since the connecting plate 8 is arranged above the movable plate 23, when the electric push rod 16 drives the movable plate 23 to move upward, the connecting plate 8 also moves upward, thereby driving the partition 7 and the sleeve plate 14 to move upward. Therefore, during the dehumidification process, the partition 7 can block the ventilation hole 6 on the inlet side of the box body 3 to prevent external moisture from entering the interior of the cabinet body 1; in addition, during the upward movement of the partition 7 and the sleeve plate 14, the spring 13 is stretched. After the dehumidification is completed, when the electric push rod 16 drives the movable plate 23 to move downward, the stretched spring 13 is reset, which can drive the partition 7 and the sleeve plate 14 to reset.

[0042] Furthermore, the exhaust mechanism includes a connecting pipe 4, the air inlet end of the connecting pipe 4 is fixedly connected to the box body 3, the air outlet end of the connecting pipe 4 is fixedly connected to the cabinet body 1, and a fan 5 is provided on the connecting pipe 4, a valve body is provided inside the connecting pipe 4, and the connecting pipe 4 is configured to be serpentine.

[0043] In this embodiment, the fan 5 is used to extract air to extract the gas inside the cabinet 1, so that the gas is dried by the dehumidification mechanism before entering the cabinet 1. In addition, the connecting pipe 4 is set to be serpentine, which can increase the air flow path. The gas can pass through the side wall of the connecting pipe 4 to exchange heat with the outside world, thereby achieving the purpose of heat dissipation.

[0044] It should be noted that this application can be used in conjunction with a corresponding control system. Sensors and controllers are installed outside the cabinet 1 to detect humidity inside and outside the cabinet 1. When the sensor detects that the humidity is higher than the set value, the sensor transmits a signal to the controller. After logical judgment, the controller outputs a control signal to drive the relay module, thereby achieving on / off or motion control of the electric push rod 54, fan 5, and other equipment. This control system supports multiple modes such as manual operation, timing control, sensor linkage, and remote control, and has the characteristics of high automation, fast response, and flexible control.
