Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of communication cabinet damp-proof type power switch as shown in Figs 1-4, packet switch body
1, induced draft fans 2 and mounting plate 3, the connection that the mounting plate 3 is fixedly mounted by side are provided on the downside of the switch body 1
Ring 4 is connect with switch body 1, and the inside of the mounting plate 3 is uniformly provided with several ventilation slots 5, the ventilation slot 5 and mounting plate
6 connection of refluence set of 3 sides welding, described flow backwards are pasted with biochemical desiccant 7 on the inner wall for cover 6, the top for flowing backwards set 6
It is provided with cored slab 8, and the lower end surface of cored slab 8 and side offer through-hole 9, and the inside of cored slab 8 is filled with drying
Agent filling block 10, when induced draft fans 2 work, the casing internal air of switch body 1 is quickly flowed, and outside air is logical
The ventilation slot 5 crossed on mounting plate 3 is blasted to the inside of switch body 1, and flows through when refluence covers 6 inside and flow backwards set 6 in air
Internal biochemical desiccant 7 contacts, and by the strong absorptive of biochemical desiccant 7, absorbs to the steam in air, and
Air is blown on cored slab 8 from set 6 is flow backwards, and is blasted in inside and the cored slab 8 of cored slab 8 by the through-hole 9 of 8 lower end of cored slab
The desiccant filling block 10 in portion comes into full contact with, to realize the effect being further dried, avoids outside air by a large amount of steam bands
