Description

Technical Field

[0001] The invention relates to the technical field of sweepers, and in particular to an airport runway sweeper capable of identifying airport runway lines. Background Art

[0002] When an aircraft is operating on an airport runway, the runway surface may be contaminated by factors such as the tire rubber left by the friction between the aircraft and the runway when the aircraft lands, the aviation fuel and dust and dirt spilled while the aircraft taxis at the airport, thus affecting the takeoff and landing of the aircraft.

[0003] In the prior art, the airport runway surface needs to be cleaned in a timely manner. Currently, the cleaning method of the runway surface is manual operation. This method not only has poor reliability and low efficiency, but also takes up precious runway use time, which is another economic loss. In order to improve work efficiency, the runway line is cleaned by a sweeper.

When the angle is offset, it is easy to cause incomplete cleaning, which requires multiple cleanings. In addition, due to the pollution left by the friction of the aircraft and the spillage of stones and other debris, the sweeper needs to perform different degrees of cleaning in the appropriate place, thereby making the entire cleaning process simpler and increasing work efficiency, avoiding secondary rework at a later stage.
