[0035] Working principle: The device is connected to the installation position through an external threaded rod. During normal use, the motor 202 is turned on through wire signal transmission. After being turned on, the rotation of the central rotating shaft 203 drives the fan blade 204 to rotate, thereby discharging the gas inside the railway tunnel and realizing the gas flow. When the device needs to be overhauled periodically, the cleaning water enters through the water inlet pipe 20101 and is transported to the spray head 300 through the pressure pump 201 and sprayed out. Then, the hydraulic telescopic member 20202 is extended through electrical control, and the rotation of the electric rotating shaft 206 drives the turning plate 205 to stand upright. Then, the operation of the motor 202 is slowly started, so that the outer walls on both sides of the fan blade 204 are cleaned by the first cleaning brush head 20204 and the second cleaning brush head 207, avoiding the long-term adsorption of dust on its outer wall. The sewage after cleaning is transported to the outside of the device through the discharge pump 106 and the discharge pipe 107 for discharge. After the cleaning is completed, the set hydraulic telescopic member 20202 and the electric rotating shaft 206 drive the connecting plate 20203 and the turning plate 205 to reset, so as not to affect the normal ventilation operation of the device.
