Description

Technical Field

[0001] The utility model relates to the technical field of maintenance warning devices, in particular to a maintenance warning device for an airport runway. Background Art

[0002] Ground construction is the fundamental guarantee for the safe landing of aircraft. Airport runways are required to be straight, wear-resistant, and have certain strength and hardness requirements. At present, concrete-based runways are more common airport runways in China. Due to the characteristics of concrete's own thermal expansion and contraction, it is difficult to avoid the problem of surface swelling, which has become one of the factors that reduce taxiing safety. In addition, water accumulation on the airport runway will cause mirror reflection and interfere with the pilot's line of sight. On rainy days, the timely discharge of accumulated water is conducive to the safe operation of the aircraft. For this reason, regular maintenance operations are required, and during maintenance, it is necessary to use the maintenance warning device to achieve the warning effect.

[0003] For example, announcement number CN113562185A discloses a warning device for airport runways, which belongs to the technical field of airport-specific equipment. By arranging width lights and reflective columns, it is convenient to indicate the width of aircraft, thereby enhancing the width indication effect. By arranging lighting and turn marking lines, it is convenient to guide the aircraft to move forward, thereby enhancing the guidance effect. By arranging solar panels and solar cells, it is convenient to provide electricity for the reflective width indication guidance device for airport runways and taxiways, thereby saving energy and being more convenient to use. By installing multiple sets of solar warning light devices on both sides of the airport runway, when the aircraft takes off, lands and taxis at night or when the airport runway needs to be closed or repaired or maintained for some reason, the solar warning light device can provide timely guidance and warning to the runway and taxiway.

[0004] However, although this type of airport runway maintenance warning device can provide a good warning for the maintenance location when in use, when inspecting runway pavements of different shapes, the warning board is often set horizontally, resulting in a low warning effect on circular road fences, which increases the tediousness of maintenance personnel in laying the warning board.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a maintenance warning device for airport runways is proposed. Utility Model Content
