The louvre blade 2102 between supporting beam 2104 is stated, by controlling the rotation of louvre blade 2102 so that connecting between louvre blade 2102
Or separate, to complete to the connection and closing between cabinet body 1 and external environment.In order to enable cabinet body when electric-powered shutter is closed
1 is isolated from the outside that effect is better, and first regulatory region 21 is vertical friendship with 2102 direction of louvre blade of the second regulatory region 23
Mistake, 2102 direction of louvre blade of first regulatory region 21 are direction from left to right, the louvre blade of second regulatory region 23
2102 directions are from direction outside to inside, and the two forms vertical interlaced angle.
As shown in figure 8, in order to enable the first regulatory region 21 is more closed when closing with the second regulatory region 23, the louvre blade
2102 both ends are respectively left connector 2105, right connector 2107, and the left connector 2105,2107 thickness of right connector are less than described hundred
The electromagnetism item 2106 of evagination is arranged on the left connector 2105 for the intermediate position of blade 2102, on the right connector 2107 setting with
2106 position of electromagnetism item, the matched indent of size electromagnetism slot 2108.In the specific implementation, adjacent louvre blade 2102
On electromagnetism item 2106 and electromagnetism slot 2108 cooperate, as on the left connector 2105 of louvre blade 2102 electromagnetism item 2106 with it is adjacent
Electromagnetism slot 2108 on 2102 right connector 2107 of left side louvre blade mutually agrees with, and the electricity on 2102 right connector 2107 of louvre blade
Magnetic slot 2108 mutually agrees with with the electromagnetism item 2106 on the left connector 2105 of adjacent the right louvre blade 2102.It is closed in electric-powered shutter
It closes, 2108 magnetism of electromagnetism item 2106 with electromagnetism slot of adjacent cooperation two-by-two is on the contrary, the two attracts each other, so that sealing effect is more
It is good；When electric-powered shutter is opened, it is powered so that the electromagnetism item 2106 of adjacent cooperation is identical as 2108 magnetism of electromagnetism slot two-by-two, two
Person is mutually exclusive, accelerates unlatching effect.In specific implementation, due to the louvre blade 2102 and two 2101 phases of frame of most two sides
It connects, so it is plane that right connector 2107 and electromagnetism slot 2108, left side are arranged on the right side of the louvre blade 2102 of the leftmost side；The hundred of the rightmost side
It is plane that left connector 2105 is arranged on the left of blade 2102 with electromagnetism item 2106, right side.
As shown in Fig. 6 and Fig. 9, the ventilation layer 22 includes moist-proof board 2201, is arranged in the moist-proof board 2201 simultaneously
The ventilation fan 2202 penetrated through.In order to avoid having brought the sundries such as dust, leaf in scavenging period into, on the ventilation fan 2202
Filter screen 2203 is set on lower both ends.
The course of work of vent cabinet 2 include: by humidity sensor 13 in cabinet body 1 in it humidity carry out real-time monitoring with
Feedback, and early warning range is set, when 1 humidity is more than certain numerical value in cabinet body, drive the first regulatory region 21 and the second regulatory region
23 electric-powered shutter is opened, and drives the rotation of louvre blade 2102 by shaft 2103 so that separating between louvre blade 2102,
It is powered simultaneously so that the electromagnetism item 2106 of adjacent cooperation is identical as 2108 magnetism of electromagnetism slot two-by-two, the two is mutually exclusive to be accelerated out
Effect is opened, cabinet body 1 is connected to outside, while ventilation fan 2202 starts, the heat in cabinet body 1 is discharged with moisture, it is external empty
Gas enters.When humidity has controlled after zone of reasonableness in cabinet body 1, electric-powered shutter is closed, and drives louvre blade by shaft 2103
So that connecting between louvre blade 2102, electromagnetism item 2106 is stuck in the electromagnetism slot on adjacent louvre blade 2102 for 2102 rotation
On 2108, and it is powered so that the magnetism of electromagnetism item 2106 with electromagnetism slot 2108 of adjacent cooperation two-by-two makes on the contrary, the two attracts each other
It is better to obtain sealing effect.
As shown in Figure 10, due to implementing to need, some high and low voltage switchgears are mounted on outdoor, in order to avoid rainwater etc. inclines
Enter, the covering 5 of 1 top of the cabinet body installation umbrella, described cover is fixedly connected between 5 and the cabinet body 1 by cap handle 4, institute
The cross-sectional area for covering 5 is stated greater than the cross-sectional area of the cabinet body 1, the protective effects such as sunshade, rain and snow are played to cabinet body 1.
The humidity sensor 13 and 21 electric-powered shutter of the first regulatory region, 23 electric-powered shutter of the second regulatory region,
There is electrical connection, 13 signal of the humidity sensor transmission and electric-powered shutter, ventilation fan 2202 between ventilation fan 2202 etc.
Opening control is that PLC is controlled, and the open and close of the electric-powered shutter, ventilation fan 2202 are believed by the humidity sensor 13
Number be associated with and control, foregoing circuit setting and PLC control be conventional arrangement, the utility model and diagram do not make specifically
It is bright.
