Further, the present invention also comprises the base that is arranged at described bottom half, described base is made up of with first division board that is positioned at the coaming plate top the coaming plate of four rectangular arranged, be provided with into two bafflers that " V " font is arranged in the described base, two bafflers are divided into upper and lower chamber with described base inside, offer the steam vent that communicates with following chamber on the base side plate, two baffler intersections are formed with the draining slit, offer the resigning hole that current supply cable passes respectively on first division board and two bafflers, resigning hole is provided with the disrance sleeve that current supply cable passes.
Further, described lower box has been horizontally disposed with second division board, offers the resigning hole that current supply cable passes on the moisture division board, and resigning hole is provided with the disrance sleeve that current supply cable passes.
The present invention has following beneficial effect:
Top cover is by interior, outer cover is formed, in, form the condensation chamber between the outer cover, during work, air exhauster is introduced the moisture in the casing in the condensation chamber, moisture condenses into water droplet after running into the condensation net, final water droplet is discharged the casing outside through spiracle, because spiracle is less and be provided with respirator, therefore, outside moisture is difficult to enter the condensation chamber from spiracle, still can be processed into the liquid discharge by the condensation net even enter the condensation chamber, guarantee the sealing of casing, prevent that moisture from entering in the casing by the hydrofuge passage, cut off replenishing of box house moisture from the source, effectively improve the moisture effect of terminal box.
Interior lid is spliced by first, second swash plate and biside plate, and the bootable drop that condenses of first, second swash plate that is in tilted layout converges downwards and finally flows to spiracle, is conducive to the discharge of liquid in the condensation chamber; Below first, second swash plate lower edge rhone is set, rhone can be accepted the drop on first, second swash plate and guide liquid into spiracle, improves hydrofuge efficient, prevents that liquid from assembling in the condensation chamber.
Heater and the temperature sensor that is connected with heater are set in the casing, temperature sensor is arranged on the minimum position of temperature in the casing, namely with the position of the outside temperature difference maximum of casing, when the temperature of the detection of temperature sensor is reduced to preset value, heater is started working, reduce the casing internal-external temperature difference, stop the water in air molecule and in casing, condense; Upper and lower heater is set in casing, can makes the box house uniformity of temperature profile, prevent from existing in the casing low temperature dead angle to produce condensation.
Intersection at first, second swash plate forms the hydrofuge slit, and the hydrofuge slit can enter the moisture that rises to the top in the casing in the condensation chamber, improves the hydrofuge effect.
Moisture absorption silica gel is set in the drying box, can be used for absorbing the moisture in the casing, when humidity sensor detects moisture and reaches preset value, then start baker the liquid in the silica gel is baked into steam, steam is guided air exhauster into through dehumidification tube, is introduced in the condensation chamber by air exhauster and carries out the condensation hydrofuge; Adopt " V " font web plate support silica gel, can increase the heating surface area of silica gel, web plate then is conducive to moisture and enters in the drying box and absorbed by silica gel in addition.
Setting has the base of first division board, and first division board can stop that moisture enters from bottom half, reduces the moisture in the casing from the source, and it also is identical purpose that second division board is set in casing; Be arranged to two bafflers that " V " font is arranged in the base, the liquid that condenses in the base can be discharged in the draining slit of guiding between two bafflers.
