The junction box is preferably an acrylic waterproof junction box 6. The junction box is a conventional setting for a distribution box and will not be described in detail here. A self-drying water vapor filter device 3 with an embedded structure is installed at the bottom of the cabinet 1, and heat dissipation windows 4 are symmetrically provided at the top of both ends of the cabinet 2, and water vapor exhaust ports 5 are symmetrically provided on both sides of the heat dissipation window 4. Acrylic waterproof junction boxes 6 are equidistantly and symmetrically distributed at the bottom of the heat dissipation window 4 and the water vapor exhaust port 5.
[0015] The self-drying water vapor filtering device 3 comprises a dust screen 7, a water vapor absorption drying device 8, a fan 9, an air duct conversion frame 10, a lane change turntable 11, a driven pulley 12, a belt 13, a driving pulley 14, a servo motor 15, an exhaust hole 16, and an exhaust duct 17. The dust screen 7 is installed at the bottom of the front end surface of the cabinet 1, and the water vapor absorption drying device 8 is installed backwards from the dust screen 7. The water vapor absorption drying device 8 can be fixed in the cabinet 1 by screws. Two groups of symmetrically distributed fans 9 are installed at the top of the water vapor absorption drying device 8, and the air duct conversion frame 10 is installed at the top of the fan 9. The middle of the top of the air duct conversion frame 10 is rotatably connected to the lane change turntable 11, and the bottom end of the lane change turntable 11 is keyed to the driven pulley 12, and the driven pulley 12 is connected to the driving pulley 14 backwards through the belt 13, and the bottom end of the driving pulley 14 is keyed to the rotating shaft of the servo motor 15. The upper surface of the lane change turntable 11 is provided with an exhaust hole 16, and an exhaust pipe 17 is installed upwardly to be in frictional contact with the exhaust hole 16, that is, the outer diameter of the bottom of the exhaust pipe 17 is equal to the inner diameter of the exhaust hole 16, and the bottom of the exhaust pipe 17 is just inserted into the exhaust hole 16, and the connection between the bottom of the exhaust pipe 17 and the inner wall of the exhaust hole 16 is achieved by the friction between the bottom of the exhaust pipe 17 and the inner wall of the exhaust hole 16. The exhaust pipe 17 is connected to the water vapor outlet 5.
[0016] The water vapor absorption and drying device 8 includes a drying box 18, an exhaust filter 19, a flame retardant woven bag 20, a resistance heating wire 21, and a calcium oxide block layer 22, wherein the exhaust filter 19 is symmetrically arranged at the top of the drying box 18, and there are two exhaust filters 19, which are embedded and symmetrically distributed on the upper surface of the exhaust filter 19; the flame retardant woven bag 20 is placed in the drying box 18, and a resistance heating wire 21 is installed inside the flame retardant woven bag 20, and calcium oxide block layers 22 are arranged above and below the resistance heating wire 21, and the resistance heating wire 21 is located in the middle of the calcium oxide block layer 22.
[0017] Working principle: First, the air outside the distribution box is passed through the dustproof net 7 by the fan 9 and enters the water vapor absorption and drying device 8, and cooperates with the internal calcium oxide block layer 22 to intercept and filter the water vapor. Then, the filtered air enters the cabinet 1 through the air duct conversion frame 10 and the exhaust hole 16 on the top of the lane change turntable 11 under the guidance of the fan 9, and then is discharged from the heat dissipation window 4, thereby achieving the effect of accelerating air circulation and heat dissipation. When the calcium oxide block layer 22 absorbs enough water vapor to be saturated, the calcium hydroxide is dried by the resistance heating wire 21. At the same time, the servo motor 15 drives the active pulley 14 to rotate, and the active pulley 14 drives the driven pulley 12 and the lane change turntable 11 to rotate through the belt 13. Then, the exhaust hole 16 on the top of the lane change turntable 11 moves to the bottom of the exhaust pipe 17, and then the water vapor evaporated by the calcium hydroxide is discharged from the cabinet 1 through the exhaust pipe 17 and the water vapor outlet 5.
