Further, described lower box has been horizontally disposed with the second division board, and dampness division board offers the resigning hole of current supply cable traverse, and resigning hole is provided for the disrance sleeve of cable traverse.
There is advantages that
Top cover is by interior, outer cover forms, in, condensation chamber is formed between outer cover, during work, dampness in casing is introduced in condensation chamber by air exhauster, dampness condenses into water droplet after running into condensation net, final water droplet is discharged outside casing through spiracle, owing to spiracle is less and is provided with respiratory organ, therefore, outside moisture is difficult to enter condensation chamber from spiracle, even if entering condensation chamber still can be processed into liquid discharge by condensation net, ensure the sealing of casing, prevent dampness from passing through dehumidifying passage and enter in casing, supplementing of box house dampness is cut off from source, it is effectively improved the moisture effect of terminal box.
Inner cap body is spliced by first, second swash plate and biside plate, and the drop of the first, second bootable condensation of swash plate being in tilted layout converges downwards and eventually flows to spiracle, is conducive to the discharge of liquid in condensation chamber；Being arranged below rhone in first, second swash plate lower edge, rhone can be accepted the drop on first, second swash plate and direct liquid towards spiracle, improves moisture exclusion efficiency, it is prevented that liquid is assembled in condensation chamber.
Casing arranges heater and the temperature sensor being connected with heater, the temperature sensor position that to be arranged in casing temperature minimum, namely maximum with the outside temperature difference of casing position, when the temperature of the detection of temperature sensor is reduced to preset value, heater is started working, reduce casing internal-external temperature difference, stop water in air molecule and condense in casing；Casing arranges upper and lower heater, box interior temperature can be made to be evenly distributed, it is prevented that casing exists low temperature dead angle and produces condensation.
Form dehumidifying gap in the intersection of first, second swash plate, the dampness rising to top in casing can be entered in condensation chamber by dehumidifying gap, improves dehumidifying effect.
Drying baker arranges moisture absorption silica gel, can be used for the dampness in respiratory box body, when humidity sensor detects that dampness reaches preset value, then start baker and the liquid in silica gel is baked into steam, steam guides air exhauster into through dehumidification tube, air exhauster introduce in condensation chamber and carry out condensation dehumidifying；Adopting inverted " v " shape web plate support silica gel, can increase the heating surface area of silica gel, additionally web plate is then conducive to dampness to enter in drying baker by absorbed on silica gel.
Arranging the base with the first division board, the first division board can stop that dampness enters from box bottom, reduces the dampness in casing from source, and arranging the second division board in casing is also identical purpose；Base is arranged to two deflectors that " V " font is arranged, the liquid condensed in the base can be discharged in the draining gap guided between two deflectors.
