Description

Technical Field

[0001] This utility model relates to the field of airport landing equipment technology, and in particular to a ground well mechanism for a military airport landing lighting system. Background Technology

[0002] In practical applications, military airports typically deploy vehicle-mounted landing searchlights on both sides of the landing area. When aircraft require landing illumination at night or in foggy weather, these vehicles are driven to both sides of the runway for illumination, and then returned to the hangar after use. This back-and-forth transportation results in insufficient mobility and flexibility. Furthermore, the stability of the vehicles is low after the addition of lifting functions to the mounted landing searchlights, and their size and height are also significant. The landing searchlight vehicles still require manual driving to their fixed positions on both sides of the runway, resulting in insufficient automation. Previously installed lighting equipment in underground wells is susceptible to damage from humid, salt spray, and extreme cold or heat environments, leading to frequent electronic component failures and short equipment lifespans. Additionally, the traditional well-type structures have weak waterproofing capabilities, making them prone to water ingress and malfunctions. Therefore, an improved technology is urgently needed to address these problems in existing technologies. Utility Model Content
