When external environment humidity is larger, the moisture signal that humidity sensor 5 exports at this time will be greater than reference circuit 101
When reference signal Vref1, voltage comparator LM1 output end can export high level at this time, and then lead conducting NPN triode Q1
Logical, the coil of such first relay K1 and the second relay K2 obtain electric, and then keep the first normally opened contact K1-1 and second normally opened
The current supply circuit of contact K2-2 closure, such actuator 3 and water pump 22 is switched on, to make actuator 3 that cover board 4 be driven to slide
(controlling cover board 4 by cylinder or electric pushrod elongation) is to cover heat release hole 11, while water pump 22 obtains electric start-up operation, carries out
It draws water work；The heat release hole 11 of distribution box, which is closed, at this time can not carry out heat dissipation work, so when distribution box rely primarily on water pump
22, which draw water, carries out water-cooling；Therefore the moisture in outside air can not be carried out in distribution box by heat release hole 11, entire distribution box
In a closed state, so ensure that the drying in distribution box；Water-cooling is carried out under the action of water pump 22 again simultaneously,
To ensure the proper heat reduction of distribution box.
It follows that the utility model, when extraneous air humidity is larger, heat release hole 11 will be closed by cover board 4, water pump 22
Start to draw water and carry out water-cooling, not only ensure that the moisture in outside air will not be entered in distribution box by heat release hole 11, but also protect
The proper heat reduction for having demonstrate,proved distribution box, when outside air humidity is smaller, cover board 4, which is sliped off, exposes heat release hole 11 to carry out
Proper heat reduction, and water pump 22 is in dormant state, such as just ensure that distribution box passes through 11 proper heat reduction of heat release hole, and is not required to out
It opens water pump 22 to radiate, avoids unnecessary power consumption.
The representative instance of above only the utility model, in addition to this, the utility model can also have other a variety of specific
Embodiment, all technical solutions formed using equivalent substitution or equivalent transformation, all falls within the model of the requires of the utility model protection
It encloses.
