the humidity sensor detects the humidity value in the main cabinet body 1 in real time, and sends the humidity value to the processor, the processor processes the humidity value, and sends a closing signal to the PLC controller 3 when the humidity value is greater than a set threshold value, the PLC controller 3 opens the electronic valve of the installation pipe 31 and starts the fan 29 after receiving the closing signal, the fan 29 pumps the air outside the main cabinet body 1 into the casing 271 through the installation pipe 31, the hose 32 and the connection pipe 30, under the filtering action of the second filter screens 273, impurities are isolated between the two second filter screens 273, the air flow passes through the second filter screens 273 and then contacts with the drying screen plate 275, the drying screen plate 275 drives the rotating rod 274 to rotate under the pushing action of the air flow, so that the air flow continuously contacts with the overturned drying screen plate 275, the drying screen plate 275 absorbs the moisture in the air flow, the air after being dried enters the main cabinet body 1 through the pipe 276, the air pressure in the main cabinet 1 rises to discharge the moist air through the through holes 22;
after humid air is exhausted, the electronic valve and the fan 29 are closed, the driving motor 9 is started to rotate positively to drive the bidirectional threaded rod 10 to rotate clockwise, when the bidirectional threaded rod 10 rotates, under the limiting action of the sliding rail 12 and the sliding block 13, the two threaded sleeves 11 are close to each other on the bidirectional threaded rod 10, the height of the lifting plate 15 is controlled to descend through the two mounting rods 14, when the mounting plate 16 touches the switch 25, the driving motor 9 is closed, the electric push rod 17 is controlled to extend out through the PLC 3, the electric push rod 17 pushes the connecting plate 18 to move until the plug 19 enters the through hole 22 to plug and seal the through hole 22, and the external humid air is prevented from entering the main cabinet body 1 through the through hole 22;
after the weather changes fine, the outside air of the main cabinet body 1 is constantly dry, further stretch out through PLC controller 3 control electric putter 17, promote the second sponge layer 38 that absorbs water to first filter screen 21 department, utilize first filter screen 21 to extrude the water on the second sponge layer 38 that absorbs water, and the water in the second sponge layer 38 that absorbs water is whole to be extruded or the evaporation back, electric putter 17 contracts, take into main cabinet body 1 inside with end cap 19, control driving motor 9 reversal drive two-way threaded rod 10 anticlockwise rotation, control two thread bush 11 and separate each other, mention lifter plate 15, a plurality of through-holes 22 of the main cabinet body 1 both sides can continue to be used for ventilation cooling.
The invention has the following beneficial effects:
1. the lifting plate can be controlled to ascend and descend by the aid of the arranged structures such as the driving motor, the bidirectional threaded rod and the threaded sleeve, the electric push rod controls the plug to extend out and block the through hole, so that the main cabinet body is sealed, external rainwater is prevented from entering the main cabinet body through the through hole in rainy days and corroding electrical elements, the plug and the through hole are controlled to be separated by the electric push rod and the driving motor in non-rainy days, ventilation and heat dissipation are carried out by the aid of the through holes in the two sides of the main cabinet body, and the ambient temperature of the electrical elements in the main cabinet body during working is reduced;
2. the first filter screen is arranged on the inner wall of the mounting frame, so that impurities in the external environment can be prevented from entering the main cabinet body through the through holes, meanwhile, after rainy days are clear, the electric push rod is retracted before the plug is retracted into the main cabinet body, the electric push rod further extends out, the second water absorption sponge layer is pushed to the first filter screen, and water in the second water absorption sponge layer is quickly extruded out through the first filter screen, so that the second water absorption sponge layer can be quickly dried;
3. the humidity sensor can detect the humidity value in the main cabinet body in real time, the position of the plug can be automatically controlled through the PLC after the humidity value is processed by the processor, the plug is controlled to plug and seal the through hole in rainy days, the plug is controlled to be separated from the through hole in dry weather, the ventilation and heat dissipation are carried out on the internal environment of the main cabinet body, the automation degree is high, and manual operation is not needed;
4. through the fan and the air drying mechanism that set up, can be when the internal humidity value of main cabinet is less than the settlement threshold value, before the end cap seals the main cabinet body, to the internal dry air of carrying of main cabinet to after discharging the moist air of the internal portion of main cabinet, reuse the end cap and carry out the sealed of the main cabinet body, thereby guarantee the dry degree of its inside air when the main cabinet body is sealed.
