In addition, a water accumulation detection sensor 404 is also arranged in the box 400, and the water accumulation detection sensor 404 is electrically connected with an alarm; wherein the water accumulation detection sensor 404 is a water immersion detector of model TR-Y12V. When the accumulated water detection sensor 404 detects that accumulated water exists in the box 400, the alarm is triggered to give an alarm, so that a maintainer is informed of the need of overhauling the box 400.

The working principle is as follows: when the fan 300 works, the fan 300 quickly sucks the outside air into the cylinder body 200 and accelerates the flow rate of the air, so that wind power is generated, the air filter barrel and the auxiliary main fan blades 208 quickly rotate under the action of the wind power, and the air entering the cylinder body 200 is filtered by the air filter barrel to obtain clean air; meanwhile, under the action of the rapid rotation of the air filter barrel, moisture adhered to the filter screen can be separated and discharged from the filter screen, so that the dryness of the filter screen is kept, clean air enters the fan 300 through the connecting shaft 204 and the exhaust pipe 302, when an air source is conveyed from an air outlet 303 of the fan 300, the first steel balls 304c in the stop loop valve 301 are stressed to compress the second spring 304d, the stop loop valve 301 is opened, the air flows through the air conveying pipe 305 through the stop loop valve 301 to enter the box 400, when the fan 300 stops working or wind power is weak, the first steel balls 304c are released, the second spring 304d pushes back the first steel balls 304c to block the first valve hole 304b, and the reverse pressure is stopped, so that the pressure maintaining function of the box 400 is completed. Because the air pressure of the box 400 is always greater than the external air pressure, the inside and the outside of the box 400 can be always kept in a dry state, and the situations that the inside and the outside of the box 400 get damp or the outside of the box 400 frosts and atmospheric air with moisture enters the box 400 due to climate in four seasons, so that the box 400 and equipment in the box 400 are corroded, the working performance of the equipment in the box 400 is influenced, the service life of the equipment is shortened, and the like are avoided.

The automatic pressure maintaining conditions in the box 400 are satisfied as follows:

when the air pressure in the box 400 reaches 80Kpa to 150Kpa, the pressure detection switch 403 controls the fan 300 to be switched on, so that the fan 300 works to maintain the pressure in the box 400; when the air pressure in the box 400 reaches 80Kpa to 150Kpa, the pressure detection switch 403 controls the fan 300 to be turned off.

When the humidity pw in the box 400 reaches 1.5-2 times of the absolute humidity (15 g/cubic meter MAX), the humidity detection switch 402 controls the fan 300 to be switched on, so that the fan 300 works, and pressure in the box 400 is maintained; when the humidity pw inside the box 400 is normal, the humidity detection switch 402 controls the fan 300 to be turned off.

When the air pressure in the box 400 is more than 80Kpa to 150Kpa, the blowdown air release valve 401 is automatically opened, and the air pressure in the box 400 is quickly discharged; when the pressure reaches 80Kpa-150Kpa, the blowdown bleed valve 401 automatically closes.

It should be noted that when the alarm is triggered to alarm, the maintainer should pay attention to opening the blowdown air release valve 401 to remove the pressure air in the box 400, and when the air pressure reaches 20Kpa, the box 400 is opened to be overhauled, so as to ensure the safety of the maintainer.

The above disclosure is only for the preferred embodiments of the present invention, however, the present invention is not limited thereto, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
