By adopting technique scheme, the solar panel arranged is when there being the sun, solar panel absorbs solar energy and produces electricity, fax be passed on blower fan and battery ventilation unit, make shutter to open ventilation, blower fan is also started working simultaneously, to carry out carrying out radiating and cooling dehumidifying in cabinet, when solar energy loses power supply, blower fan is turned off, the shutter of ventilation unit also can be closed simultaneously, prevent under atrocious weather, cause moisture to enter formation condensation.
The utility model is set to further: described electromagnetic drive mechanism comprises shaft, electromagnet and driving box, described driving box one side is provided with the through hole stretched out for shaft, one end of described shaft is fixedly connected with snap ring, and be arranged on together with snap ring in driving box, the other end of described shaft passes the vane hinge of through hole and shutter, described electromagnet is arranged on the another side of opposing through-bores in driving box, and described electromagnet is electrically connected with solar panel.
By adopting technique scheme, electromagnetic drive mechanism is electrically connected with solar panel, the folding of shutter and the operating state of blower fan can be made to be consistent, make the working effect of blower fan more obvious, blower fan can not be caused under shutter is closed also in work, and by solar energy, electromagnetic drive mechanism is powered, the closed condition of its shutter under any environment not having the sun can be ensured, moisture can not be made to enter in cabinet.
The utility model is set to further: described blower fan is arranged on the shutter.
By adopting technique scheme, make the ventilation effect of blower fan to cabinet better.

Embodiment
Referring to figs. 1 through Fig. 6, the ring main unit embodiment of the utility model intelligent aeration dehumidifying safety is described further.
A kind of ring main unit with ventilation drying function, comprise cabinet 2, heat sink is provided with in described cabinet 2, described heat sink comprises on the solar panel 1 being arranged on cabinet 2 top and the side plate being arranged on cabinet 2 makes blower fan 3 that is outdoor and cabinet 2 inner air flow, described solar panel 1 is electrically connected with blower fan 3, two side plates of described cabinet 2 are provided with electromagnetism ventilation unit, described electromagnetism ventilation unit comprises the shutter 4 that is arranged on cabinet 2 both sides and for driving the electromagnetic drive mechanism of shutter 4 folding, described electromagnetic drive mechanism is arranged on shutter 4 upper end.
Described electromagnetic drive mechanism comprises shaft 41, electromagnet and driving box 42, described driving box 42 one side is provided with the through hole stretched out for shaft 41, described arrange through hole one facing to shutter 4, one end of described shaft 41 is fixedly connected with snap ring 43, and be arranged on together with snap ring 43 in driving box 42, the blade 6 that the other end of described shaft 41 passes through hole and shutter 4 is hinged, described electromagnet is arranged on the another side of opposing through-bores in driving box 42, and described electromagnet is electrically connected with solar panel 1.
Specific implementation process: as preferentially, solar panel 1 is in the present embodiment the 135W solar panel 1 of KD135GH-2PU model, when there being the solar time, under the long-time irradiation of the sun, solar panel 1 absorbs solar energy and produces electricity, electricity is supplied to blower fan 3 and electromagnet, electromagnet energizing magnetic, shaft 41 is upwards adsorbed onto on electromagnet by electromagnet overcomes shaft 41 gravity by magnetic, because shaft 41 is upwards adsorbed onto on electromagnet, shaft 41 other end and shutter 4 blade 6 hinged, this is hinged connects in hinge 5 mode, shaft 41 arranges a slice of hinge 5, another sheet of hinge 5 is set on inside blade 6, by hinged for this two panels hinge 5 to reach the folding that shaft 41 energy drive vane 6 carries out shutter 4, the mobile inner end of the blade 6 of shutter 4 that drives of shaft 41 is upwards rotated, the shutter 4 made is in ventilation state, and blower fan 3 is also started working after powered up, equipment in blower fan 3 pairs of cabinets 2 of ventilating opening carries out ventilation and heat, when there is no the sun or sunlight is more weak, solar panel 1 just loses electric power, thus blower fan 3 and electromagnet power-off simultaneously, electromagnet just loses magnetism, and the absorption affinity that shaft 41 loses electromagnet just moves down by the effect of gravity, due to the setting of snap ring 43, one end of shaft 41 can not be dropped out completely in driving box 42, the inner end of the blade 6 of shutter 4 is moved down, thus closes shutter 4, extraneous moisture is no longer entered in cabinet 2.
In sum, by the electromagnet of setting and coordinating of shaft 41, and powered by solar panel 1, make to control the folding of shutter 4 and the operating state of blower fan 3 by solar energy, ensure that shutter 4 is be in closed condition under without the weather of sunlight, other materials such as moisture can not be made to enter in cabinet 2 and produce potential safety hazard.
The above is only preferred implementation of the present utility model; protection range of the present utility model is also not only confined to above-described embodiment; all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model; should be understood that; for those skilled in the art; do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
