Description
Technical Field
[0001] The present application relates to the technical field of power distribution cabinets, and more specifically, to a moisture-proof power distribution cabinet and a method for using the same. Background Art
[0002] The distribution cabinet is the final equipment of the power distribution system. In order to maintain ventilation and heat dissipation, the distribution cabinet will be equipped with vents on the cabinet. Due to the high humidity in some areas or in the rainy season, moisture in the air can easily enter the interior of the distribution cabinet through the vents and cause damage to electrical components.
[0003] The document with prior art publication number CN210224615U provides a moisture-proof distribution cabinet, including a distribution cabinet body and a moisture-proof component. The moisture-proof component is arranged on the left and right sides of the distribution cabinet body. An air outlet is arranged at the rear of the distribution cabinet body. A placement groove is arranged on the distribution cabinet body at the air outlet. A single-opening fan is arranged on the top of the placement groove. The single-opening fan is clamped with the bottom of the placement groove, and a moisture-proof plate is arranged in the placement groove. The device is provided with moisture-proof parts at both the air inlet and the air outlet. The moisture-proof box at the air inlet uses a blocking plate to form an air guide channel for the moisture-proof box. Then, the air inlet entering from the first box must pass through the ventilation holes on the partition and then be dehumidified by the activated carbon balls before entering the second box, and then enter the main body of the distribution cabinet from the side wall of the second box; finally, the wind passes through the air outlet of the distribution cabinet; in order to prevent humid gas from entering the interior of the distribution cabinet from the air outlet, openings are provided on the placement slot, moisture-proof box, and single-opening fan of the distribution cabinet, and the moisture-proof box is filled with moisture-proof boards and moisture-absorbing desiccant or activated carbon. Multiple protections are provided to prevent water vapor from entering the interior of the distribution cabinet and affecting the normal operation of the electrical components of the distribution cabinet.
[0004] Although the above-mentioned prior art solution can achieve relevant beneficial effects through the structure of the prior art, it still has the following defects: the desiccant can only perform dehumidification operation within a certain absorption range. When the desiccant absorbs too much moisture, the desiccant needs to be replaced, otherwise the drying effect will be lost.
[0005] In view of the above-mentioned related technologies, the inventor believes that the desiccant can be recycled by setting a circulation component. In view of this, we propose a moisture-proof distribution cabinet and a method of using the same. Summary of the invention

The hot air discharged from the distribution box passes through the desiccant in the air outlet channel, effectively drying the desiccant, thereby achieving the effect of dehumidifying on one side and drying on the other side; the driving component drives the regulating component to switch the desiccant in the air outlet channel and the air inlet channel, thereby realizing the recycling of the desiccant, the heating rod heats the gas to a set temperature and then sends it into the air outlet channel and passes through the desiccant through the ventilation fan, dries and dehumidifies the switched desiccant, and finally discharges the gas from the air outlet of the air outlet channel to achieve gas circulation. The humidity of the gas entering the diffusion chamber is detected by the sensor in the diffusion chamber. When the humidity reaches the set value, the desiccant in the air inlet channel and the air outlet channel is switched.

The return air zone is connected to the conversion box. The desiccant in the air outlet passage is in the drying chamber. The air outlet of the air outlet chamber is connected to the outside. A ventilation fan is installed at the air outlet of the air outlet chamber. The storage assembly includes a storage tube, which is fixedly installed in the box body and is located in the dehumidification bin and the drying bin. A plurality of supporting mesh plates are arranged in the storage tube, and the desiccant is distributed on the plurality of supporting mesh plates. The aperture of the supporting mesh plates is smaller than the diameter of the desiccant. A sleeve is arranged at the bottom of the storage tube, and the adjustment assembly is rotatably connected to the sleeve. The adjusting assembly includes a rotating shaft and a partition. The rotating shaft is rotatably connected to the sleeve. A plurality of partitions are fixedly arranged on the rotating shaft. The partitions are rotatably connected to the storage tube.

2. The moisture-proof distribution cabinet according to claim 1, characterized in that: The air inlet hole is arranged obliquely, and the height of the outer opening of the air inlet hole is lower than the height of the inner opening.
3. The moisture-proof distribution cabinet according to claim 1, characterized in that: The driving assembly includes a motor, a support shaft and a first bevel gear. The motor is installed in the box body. The output shaft of the motor is fixedly connected to the first gear. The support shaft is rotatably connected to the box body. The support shaft is connected to the second gear. The first gear and the second gear are meshed for transmission. Both ends of the support shaft are connected to the second bevel gear. The first bevel gear is fixedly arranged on the rotating shaft. The first bevel gear and the second bevel gear are meshed for transmission.
4. The moisture-proof power distribution cabinet according to claim 1, characterized in that: Temperature and humidity sensors are arranged in the working area of the box body, in the conversion box, in the diffusion bin and in the storage tube to monitor the temperature and humidity at the corresponding positions.
5. The method for using the moisture-proof power distribution cabinet according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. The ventilation fan is turned on, and the cold air from the outside enters the air inlet channel from the air inlet hole and passes through the desiccant in the dehumidification chamber. After drying, the air enters the diffusion chamber and is driven by the ventilation fan into the working area to cool down the components. S2. The gas flows away the heat of the components and enters the air outlet box, the connecting pipe, the conversion box, and the air outlet channel through the ventilation fan. The gas passes through the drying chamber to dry the desiccant inside and is finally discharged from the air outlet of the air outlet channel. S3. When the temperature and humidity sensor in the diffusion chamber detects that the humidity reaches the set threshold, the motor drives the first gear to rotate, and drives the second gear, the support shaft and the second bevel gear to rotate through meshing transmission. The second bevel gear drives the first bevel gear, the rotating shaft and the partition to rotate, so that the desiccant in the air inlet channel and the air outlet channel is switched; S4. The heating rod heats the air, and the flowing gas drives the hot air into the drying chamber to dry the desiccant until the temperature and humidity sensor in the drying chamber detects that the humidity reaches the set threshold.
