As shown in fig. 6 and 7, when the barrier plate 6 is in the opened state, the push plate 32 is at the push port 22 under the elastic force of the return spring 36 and seals the push port 22, so that the possibility of the drying sheet 10 in the storage tube 19 coming into contact with air can be reduced. When the baffle plate 6 is closed, the side wall of the baffle plate 6 is abutted and pushes the push rod 31 to move into the box body 1, and under the action of the first inclined surface 34 and the second inclined surface 35, the push rod 31 moves to push the push plate 32 to move into the storage tube 19, and the push plate 32 moves to drive the reset block 46 to compress the reset spring 36. The pushing plate 32 moves to push the drying sheet 10 downward, so that the drying sheet 10 can push the first hinged door 24 to rotate, when the first hinged door 24 is opened against the elastic force of the torsion spring 39, the drying sheet 10 falls down under its own weight, and when the drying sheet 10 emerges from the storage tube 19, it is located between the plurality of guide ropes 33, the side wall of the drying sheet 10 is slidably connected to the guide ropes 33, and the drying sheet 10 is inserted into the groove 30 of the storage table 26 under the guide of the guide ropes 33.
As shown in fig. 7, when the first hinge door 24 is opened, the first hinge door 24 rotates to drive the first hinge rod 38 to rotate, the first hinge rod 38 rotates to drive the first sprocket 42 to rotate, the first sprocket 42 rotates to drive the second sprocket 43 to rotate, and the second sprocket 43 rotates to drive the second hinge rod 40 to rotate, so that the second hinge door 41 is opened, and the drying sheet 10 on the storage table 26 falls into the recovery box 28 from the second hinge door 41. When the drying sheet 10 just leaves the first hinge door 24, the first hinge door 24 is rotated to be closed under the action of the torsion spring 39, and the first hinge door 24 is closed to drive the second hinge door 41 to be closed, so that a new drying sheet 10 can be placed in the groove 30 and dehumidify the inside of the box.
As shown in fig. 1 and 6, and in combination with fig. 7, when the barrier plate 6 is opened, the barrier plate 6 is away from the push rod 31, the push plate 32 moves outside the storage tube 19 under the elastic force of the return spring 36, and the push plate 32 moves to push the push rod 31 to move inside the storage tank 4; when the return spring 36 is in a natural state, the pushing plate 32 is at the pushing port 22, and at this time, the pushing plate 21 in the storage tube 19 pushes the plurality of drying sheets 10 to move together under the pushing force of the first spring 20, so that the upper part of one drying sheet 10 is opposite to the pushing port 22, and the lower part is abutted against the first hinged door 24, thereby facilitating the next replacement of the drying sheet 10 on the storage table 26.
The implementation principle of the embodiment of the application is as follows: when the rain does not fall, the baffle plate 6 is in an open state, so that the ventilation inside and outside the box body 1 can be increased, and the heat dissipation of the transformer 14 is facilitated. When raining, the sensor 8 transmits signals of raining days to the driving assembly 9, and the baffle plate 6 is closed under the action of the driving assembly 9, so that the possibility that rainwater and moist air enter the box body 1 from the through hole 3 is reduced; when the sensor 8 receives a clear weather signal, the driving assembly 9 drives the baffle plate 6 to open.
Moisture entering the tank before the barrier 6 is closed can be absorbed by the replacement dryer sheet 10 on the storage table 26, and the air in the tank 1 can be dehumidified, thereby reducing the possibility of short circuits in the transformer 14.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
