Problems solved by technology

Most of the existing aircraft engine air intake protection covers are external windproof sand cloth covers. The current windproof gauze cover is only equipped for a single model, and the size of the engine inlet of different models is different, so the windproof gauze cover is not suitable for most models

Abstract

An umbrella-shaped protection device used in an engine air inlet channel comprises an umbrella stand structure, umbrella cloth installed on the umbrella stand structure and an elastic compensation ring installed on the umbrella stand structure and located on the periphery of the umbrella cloth. The umbrella stand structure comprises a sleeve telescopic rod, a supporting seat, a combined sliding seat, a plurality of transverse supporting rods, a plurality of inclined supporting rods and a loosening pin, the sleeve telescopic rod is sleeved with the combined sliding seat in a sliding mode, and a buckling mechanism is arranged in the combined sliding seat. The loosening pin penetrates through the supporting seat, extends into the sleeve telescopic rod and is matched with the buckling mechanism, so that the umbrella stand structure can be unfolded or folded. When the umbrella-shaped protection device used in the engine air inlet channel is used, a worker controls the umbrella stand structure to be unfolded or folded from the top of the umbrella stand structure, operation from the interior of an engine is not needed, protection of the internal structure of the engine is better facilitated, the unfolded umbrella stand structure is better attached to the inner wall of the engine air inlet channel, and the service life of the engine air inlet channel is prolonged. Foreign matters can be effectively prevented from entering the engine.

Description

technical field [0001] The invention relates to the technical field of aircraft ground maintenance, in particular to an umbrella-shaped protective device used in an engine intake passage. Background technique [0002] The engine is a necessary power component of the aircraft and one of the main components of the aircraft. Its performance is directly related to the use and safety of the aircraft. During the regular inspection and maintenance of the engine, it is often necessary to stay on the ground. In order to prevent foreign objects from entering the engine, it is often necessary to protect the engine intake. Most of the existing aircraft engine air intake protection covers are external windproof sand cloth covers. The current windproof gauze cover is only equipped for a single model, and the size of the engine inlet of different models is different, so the windproof gauze cover is not suitable for most models. Contents of the invention [0003] The object of the prese...
