DETAILED DESCRIPTION

[0024] See also Figure 1-5 The utility model provides a technical solution: a high-voltage distribution cabinet with a dehumidification function, comprising:

[0025] Power distribution cabinet 1;

[0026] A dehumidification component is arranged at the exhaust fan position of the power distribution cabinet 1, and the dehumidification component is used to discharge the humid air inside the power distribution cabinet 1. The dehumidification component includes a liquid accumulation cover 2 fixedly installed inside the power distribution cabinet 1, and the inside of the liquid accumulation cover 2 is respectively fixedly installed with a ventilation partition 12, an evaporator coil 13, a condenser coil 14 and a heat conducting plate 15, and an air compressor 16 is fixedly installed at the bottom of the liquid accumulation cover 2, an air intake cover 3 is fixedly installed at one end of the liquid accumulation cover 2, and a fan 5 for suction is fixedly installed on the surface of the air intake cover 3, and a mounting bracket 4 is fixedly installed on the surface of the air intake cover 3, and the fan 5 is fixedly installed. It is fixedly installed on the inner wall of the mounting bracket 4, an air inlet is provided at one end of the air inlet hood 3 corresponding to the position of the fan 5, a drain port is provided at one end of the bottom of the liquid accumulation hood 2, and the drain port is flush with the middle position of the brush 8, the evaporator coil 13 and the condenser coil 14 are respectively fixedly installed on the front side end and the rear side end of the ventilation partition 12, and one end of the evaporator coil 13 and the condenser coil 14 are connected to the air compressor 16, and the air compressor 16 is fixedly installed on the inner wall of the power distribution cabinet 1, and the front and rear ends of the guide frame 6 are both provided with gaps, so that the wind sucked by the fan 5 can pass through the liquid accumulation hood 2;

[0027] When the above structure is in use, the air inside the distribution cabinet 1 is blown toward one end of the air inlet hood 3 through the operation of the fan 5. Since an air inlet is provided at one end of the air inlet hood 3 corresponding to the position of the fan 5, the air enters the interior of the liquid accumulation hood 2 through the air inlet and first contacts the evaporator coil 13, so that the moisture in the air is condensed by the cold, and forms water droplets that drip from the surface of the heat conduction plate 15 and the evaporator coil 13 to the bottom of the inner wall of the liquid accumulation hood 2. The condensed air passes through the ventilation partition 12 and the condenser coil 14 and is discharged outward, thereby completing the purpose of dehumidifying the distribution cabinet 1.

[0028] A self-cleaning filter assembly is arranged inside the liquid accumulation cover 2, and the self-cleaning filter assembly includes a guide frame 6 fixedly embedded in the middle of the liquid accumulation cover 2, and the guide frame 6 is fixedly installed on the surface of the air intake cover 3, and a flexible filter screen 7 is movably connected to the surface of the guide frame 6, and a brush 8 is fixedly installed at the bottom of the inner wall of the liquid accumulation cover 2, and the brush 8 is tightly fitted with the surface of the flexible filter screen 7, and the side wall of the liquid accumulation cover 2 corresponding to the position of the brush 8 is rotatably connected to a drive shaft 9 through a bearing, and a gear 11 is fixedly installed on the surface of the drive shaft 9, and the gear 11 is meshed with the inner wall of the flexible filter screen 7, and the drive shaft 9 is driven by a drive motor. The surface of 9 is rotatably connected with a fixing seat 10 through a bearing, and the fixing seat 10 is fixedly installed at the bottom of the inner wall of the guide frame 6. The inner wall of the flexible filter screen 7 corresponding to the position of the gear 11 is provided with a tooth pattern, and the bottom of the guide frame 6 corresponding to the position of the gear 11 is provided with a through groove, so that the gear 11 passes through the through groove and meshes with the flexible filter screen 7. Both ends of the guide frame 6 are provided with guide grooves, and both ends of the flexible filter screen 7 corresponding to the guide groove are respectively fixedly installed with guide bars, and the guide bars are movably connected in the guide grooves, so that the guide bars and the guide grooves cooperate to guide the relative movement of the guide frame 6 and the flexible filter screen 7.

[0029] When the above structure is in use, the driving motor drives the driving shaft 9 to rotate, which in turn drives the driving shaft 9 to rotate the gear 11, and the gear 11 drives the guide frame 6 to move on the surface of the flexible filter screen 7, and by providing the guide groove and the guide strip, the guide frame 6 can move smoothly on the surface of the flexible filter screen 7 and move relative to the brush 8. Since the drain outlet is located in the middle of the brush 8, the condensed water at the bottom of the liquid collection hood 2 will always wet the mounting bracket 4, and the brush 8 can effectively clean the surface of the flexible filter screen 7, thereby filtering the air entering the liquid collection hood 2.

[0030] Working principle: When in use, the utility model blows the air inside the power distribution cabinet 1 to one end of the air inlet hood 3 through the operation of the fan 5. Since the air inlet hood 3 is provided with an air inlet at one end corresponding to the position of the fan 5, the air enters the interior of the liquid accumulation hood 2 through the air inlet, and first contacts the evaporator coil 13, so that the moisture in the air is condensed by the cold, and forms water droplets that drip from the surface of the heat conduction plate 15 and the evaporator coil 13 to the bottom of the inner wall of the liquid accumulation hood 2. The condensed air passes through the ventilation partition 12 and the condenser coil 14 and is discharged outward, thus completing the purpose of dehumidifying the power distribution cabinet 1.

[0031] When the self-cleaning filter assembly is working, the fan 5 blows the wind inside the distribution cabinet 1 to the inside of the liquid collection cover 2 through the air inlet of the air inlet cover 3, so that the air will first pass through the flexible filter screen 7 and filter the air through the flexible filter screen 7. After long-term use, the surface of the flexible filter screen 7 is attached with dirt, which affects the air intake efficiency. At this time, the driving motor drives the driving shaft 9 to rotate, and then the driving shaft 9 drives the gear 11 to rotate, and the gear 11 drives the guide frame 6 to move on the surface of the flexible filter screen 7. By setting the guide groove and the guide strip, the guide frame 6 can move smoothly on the surface of the flexible filter screen 7. The surface moves, and when the flexible filter screen 7 moves, the flexible filter screen 7 and the brush 8 will move relative to each other. Since the drain port is located in the middle of the brush 8, the condensed water at the bottom of the liquid accumulation cover 2 will always wet the mounting bracket 4, and the brush 8 can effectively clean the surface of the flexible filter screen 7, so as to filter the air entering the liquid accumulation cover 2. At the same time, the surface of the flexible filter screen 7 can be self-cleaned by the relative movement of the flexible filter screen 7 and the brush 8, so as to avoid dirt adhering to the surface of the evaporator coil 13 and the condenser coil 14 and affecting the dehumidification efficiency.

[0032] At the same time, when the condensed air flows to the outside of the liquid accumulation cover 2, the air will pass through the condenser coil 14 and pass through the flexible filter 7 again. Since the air is heated when passing through the condenser coil 14, when the heated air passes through the flexible filter 7, it will dry the wet flexible filter 7, thereby preventing the moisture in the flexible filter 7 from affecting the filtering efficiency of the flexible filter 7.
