The invention relates to a cleaning vehicle for an airport. The cleaning vehicle comprises a main body, a
sewage tank, a cleaning tank, a cleaning device, a collecting
pipe and four wheels, and further comprises an anti-freezing mechanism and an
impurity removing mechanism, the anti-freezing mechanism comprises a heating box, a heating
pipe, a reflecting plate, a rotating
assembly, two supporting assemblies and two connecting pipes, and the
impurity removing mechanism includes a filter screen, a pressing plate, an auxiliary
assembly, two telescopic rods and two lifting assemblies. According to the cleaning vehicle for the airport, the cleaning box is heated through the anti-freezing mechanism, the probability that clear water in the cleaning box is frozen is reduced, and therefore the ground cleaning work cannot be affected, so that the equipment reliability is improved; and through the
impurity removing mechanism, the function of separating
sewage from impurities is achieved, the situation that the impurities block a
sewage discharge pipe when the sewage is discharged is avoided, the influence on the
sewage discharge work is prevented, and the equipment reliability is improved.
