as exemplified by the first one-way vent 311 of the rotating casing 31 being located inside the casing 11, the first one-way vent 311 only allows air to flow out from the inside of the rotating casing 31, the second one-way vent 312 only allows outside air to enter the rotating casing 31 in one way, the ventilating fan assembly 2 accelerates the air circulation between the inside of the distribution box 1 and the outside, the external air enters the rotary shell 31 through the second one-way air hole 312, and then enters the shell 11 through the first one-way air hole 311 after being dried by the drying agent, in cold winter, the hot air device 61 and the water removal device 62 are directly activated, so as to preheat the rotating shell 31 and the drying agent therein, therefore, after the cold air passes through the rotating shell 31 and the drying agent with higher temperature, moisture can be separated out from the side wall of the rotating shell 31 and the drying agent, and the moisture in the cold air can be prevented from being separated out from the electronic equipment on the power distribution equipment mounting frame 12;
when the drying agent in the rotary shell 31 needs to be dried, the specific process is as follows: firstly, the rotating shell 31 is driven to rotate 180 degrees by the driving part 4, at this time, the first unidirectional air vent 311 on the rotating shell 31 is positioned at the outer side of the shell 11, then the hot air device 61 and the dewatering device 62 are started, the dry hot air discharged by the hot air device 61 enters the rotating shell 31 through the first central pipe 32, the moisture in the desiccant can be evaporated in the process that the dry hot air flows upwards from the bottom of the rotating shell 31, and finally the dry hot air is discharged into the dewatering device 62 through the second central pipe 33 in the form of water vapor, the dewatering device 62 separates out the moisture in the water vapor by using the condensation principle, the dewatering device 62 is also provided with a water discharge pipe for discharging the moisture to the outer side of the distribution box 1, and the air from which the moisture is removed enters the hot air device 61 to be heated, and has the characteristic of automatically drying the desiccant, because the first unidirectional air vent 311 is positioned at the outer side of the shell 11 at this time, the second unidirectional air vent 312 is positioned at the inner side of the shell 11, therefore, the water vapor in the rotary shell 31 can be discharged to the outer side of the shell 11 only from the first one-way vent 311, so that the water vapor is prevented from entering the shell 11, and the moisture-proof effect is good;
in hot and humid summer, the dehumidifying mechanisms on both sides of the distribution box 1 work intermittently and independently, that is, when one of the dehumidifying mechanisms is responsible for removing moisture in air entering and exiting the distribution box 1, the dehumidifying component 3 in the other dehumidifying mechanism adjusts the positions of the first one-way air vent 311 and the second one-way air vent 312 by rotating 180 degrees, and the drying component 6 is used for drying the drying agent in the dehumidifying component 3;
when the drying device is used in spring or autumn, the driving part 4 drives the rotating shell 31 to rotate 90 degrees in a reciprocating manner according to a certain frequency to remove moisture in the drying agent, and the side of the rotating shell 31 after rotating 90 degrees, which is provided with the first one-way air hole 311 or the second one-way air hole 312, is perpendicular to the shell 11, so that when wind blows to the first one-way air hole 311 or the second one-way air hole 312, the moisture in the drying agent can be removed by utilizing the evaporation effect of natural wind, and it should be noted that the rotating shell 31 rotating back and forth is similar to the wings of birds to play a role in accelerating air circulation, not only can the evaporation of the moisture in the drying agent be accelerated, but also the purpose of heat dissipation of the distribution box 1 can be achieved under the condition that the ventilation fan component 2 is turned off, and under the condition that the drying component 6 and the ventilation fan component 2 do not work, still can realize the heat dissipation of block terminal 1 and get rid of the function of the moisture in the drier, possess the characteristics that energy loss is little and operation maintenance cost is low.
In conclusion, the design that the rotary shell 31, the first one-way air hole 311, the second one-way air hole 312 and the driving portion 4 are combined together not only has the function of removing moisture in air in the process of circulating air between the inside of the shell 11 and the outside, but also can prevent water vapor generated in the process of drying the drying agent by the drying component 6 from entering the shell 11, so that the manpower, material resources, financial resources and the like in the process of replacing the drying agent are reduced while the cyclic utilization of the drying agent is ensured, and the characteristics of good moisture-proof effect and low operation and maintenance cost are achieved.
