[0026] Working principle

[0027] The working principle of this utility model is as follows: When installed in a tunnel, the fan casing 31 is fixed to the installation location by bolts on the fixing seat 4. Then, the drive motor 34 drives the fan blades 35 to rotate to generate strong air for ventilation. During use, when the humidity sensor 38 detects that the internal humidity is too high and there is too much water accumulation, it opens the first solenoid valve 53 and drives the negative pressure pump 55 to generate negative pressure in the collection tank 54. Then, the water is sucked out and discharged through the assembly pipe 51 and the drain head 52. During maintenance, the vibration sensor 36 can detect the frequency of vibration during operation to know its working status. At the same time, the infrared temperature sensor 37 can detect the temperature of the working parts of the motor 34 and the fan blades 35 after stopping to know its lubrication status. In this way, maintenance can be carried out.
