Double-section type rotatable easy-to-fold navigation aid lamp

Abstract

The invention relates to the technical field of navigation aid lamps, and particularly relates to a double-section type rotatable easy-to-fold navigation aid lamp which comprises a base, a stand column fixedly arranged on the base, a lamp pole connected to the upper end of the stand column and a lamp source arranged at the top of the lamp pole, and easy-to-fold structures are arranged at the bottom and the upper end of the stand column; the easy-to-fold structure at the bottom of the stand column comprises a flange plate and a rivet which are fixedly arranged on the base; the easy-to-fold structure at the upper end of the stand column comprises a fixing piece on the stand column, a sleeve welded to the fixing piece and a rotating ring rotatably arranged on the fixing piece; and the fixing piece is connected with the rotating ring through a pin shaft, and the rotating ring is connected with the lamp pole through a rotating shaft. Through the rotatable easy-to-fold structure at the bottom of the stand column and the easy-to-fold structure at the upper end of the stand column, when the navigation aid lamp is impacted, the lamp post and the stand column can fall down at the same time or only the lamp post of the upper structure falls down, the height of the lamp post is reduced to the maximum extent, the aircraft is prevented from being damaged, and damage to the lamp pole can also be reduced.

Description

technical field [0001] The invention relates to the technical field of navigation lights, in particular to a double-stage rotatable and easy-folding navigation light. Background technique [0002] Airport navigation lights are indispensable guidance equipment for airport construction. They can provide pilots with runway position, direction and alignment guidance, so that pilots can land safely under the condition of visual reach, and ensure the smooth operation of aircraft at night and in complex weather conditions. Visual aids for takeoff, landing and taxiing. [0003] According to ICAO document No. 9157 "Airport Design Manual Part VI - Fragility", the support structures of all obstacles in the airport operating area should be set to be the lightest and easy to break, bend or yield. The folding rod ensures that when the aircraft runs irregularly and hits an obstacle, the easy-breaking rod can be destroyed quickly, so as to minimize the damage to the aircraft. According to...

Problems solved by technology

[0004] According to the above requirements, approach lights 300m away from the entrance of the airport runway usually need to be installed on a breakable pole longer than 12m. The pillar above 12m is a breakable pole, and the pillar below 12m will also cause harm to the aircraft.

[0005] At present, the pillars of the navigation lights are generally provided with easy-breaking points, and the pillars are broken at the points when they are subjected to external forces. However, although this can reduce the damage to the aircraft, it will cause excessive damage to the navigation lights.
