Description

Aircraft fuel oil drain device

Technical Field

The utility model relates to the technical field of oil drainage devices, in particular to an aircraft fuel oil drainage device.

Background

According to the maintenance technical requirements, fuel oil release work needs to be carried out after the performance of the aircraft entering a factory is checked, so that the disassembly and inspection work can be carried out safely at a later stage. The traditional oil drainage mode is as follows: an oil discharge gun is adopted, the funnel opening is aligned to the oil discharge nozzle, the lower end of the oil gun is aligned to the oil drum, and the oil gun is held by hands until fuel oil is completely discharged. This oil drain mode is owing to adopt the handheld oil drain of manpower at the oil drain in-process, and the personnel of having had of a specified duration control the difficulty, the condition that the fuel leaked often can appear, simultaneously, the oil gun often uses the iron sheet to make, and aircraft coating also can be damaged to sharp-pointed edges and corners, owing to lack electrostatic protection during the oil drain, human static also probably arouses deflagration when the fuel releases, brings serious aviation incident.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome one or more defects in the prior art and provide an aircraft fuel oil discharging device.

The purpose of the utility model is realized by the following technical scheme: the utility model provides an aircraft fuel oil drain device, includes containing box and support base, the containing box sets up on the support base, the vertical connecting rod that is provided with on the support base, be provided with the telescopic link in the connecting rod, through bolted connection between connecting rod and the telescopic link, be provided with a plurality of screw holes that match with the bolt on the telescopic link, the telescopic link upper end is provided with the funnel, be provided with the rubber sleeve on the funnel, the pipe department of funnel lower extreme is provided with the oil drain hose.

According to the utility model, the storage box is provided with the handrail, and the arrangement of the corresponding handrail can make the fuel oil discharging device more convenient to move.

According to the utility model, the lower end of the containing box is provided with a plurality of rollers, and the fuel oil discharging device can be conveniently moved by arranging the plurality of rollers.

Optionally, the bracket base is detachably provided with the static releaser, and the static releaser is used for eliminating static electricity and preventing fuel oil from deflagration.

Optionally, the roller is a universal wheel with a brake, and the roller can stop rolling at an ideal position by arranging the universal wheel with the brake, so that the stability of the fuel oil discharging device is guaranteed.

The utility model has the beneficial effects that:

1. the utility model reduces the working intensity of personnel, improves the maintenance working efficiency, improves the safety and the convenience of fuel oil release, avoids the fuel oil leakage and deflagration risks caused by personnel, is suitable for all upper single-wing navigation airplanes, and realizes the convenient fuel oil release work

2. The utility model is provided with the static releaser which is used for eliminating the static electricity of the human body and avoiding the combustion of fuel oil caused by the static electricity.
