Problems solved by technology

[0004] It can be seen that the fuel depositing tool in the prior art requires the ground crew to lift for a long time. Considering the narrow space inside the wing bulge of the aircraft, such lifting operation is very inconvenient
In addition, because the inside of the wing bulge of the aircraft is very dark, it is difficult for the ground crew to align the valve opening device for depositing the sedimentation tool with the fuel discharge sedimentation valve, which will cause the position of the aircraft to release the sedimentation valve to be in the same position as the sedimentation tool. Staggered, which will not only damage the sedimentation valve, but also easily cause fuel sediment leakage

Embodiment Construction

[0028] Such as figure 1 Shown, aircraft fuel oil of the present invention puts precipitation tool and comprises:

[0029] Holding cup 3, which is used to hold the sediment released from the aircraft fuel discharge sedimentation valve, the holding cup is made of transparent material, and a rubber holder 2 is arranged on the top, and the rubber holder 2 is made of soft rubber It can fit the aircraft skin around the sedimentation valve, which can prevent fuel spillage and provide support for tools;

[0030] Support rod body 4, the front part of support rod body 4 has thread, it passes the bottom of described holding cup 3, and fixes holding cup 3 with round nut, the top perforation of described support rod body 4 is provided with opening head. The opening head includes the opening head assembly 11, the cutter head assembly 11 is made up of the opening cutter head 1, the fastening screw 6, and the knife holder spring 5, wherein the front part of the opening cutter head 1 is a scr...

Abstract

The invention discloses an airplane fuel precipitate discharging tool which is used for discharging precipitates in a fuel tank by opening an airplane fuel precipitate discharging valve in an airplane wing rectification bulge. The airplane fuel precipitate discharging tool comprises an opening device, an illumination device, a containing cup, a rod body, a support plate and the like. Because the airplane fuel precipitate discharging tool disclosed by the invention is fixed by virtue of the support plate, the airplane fuel precipitate discharging tool does not need to be lifted by the hands of people, and is convenient and labor-saving in operation. In addition, the tool is provided with the support plate and a support spring, the function that the balance of the weight variation of a liquid in the containing cup of the tool and the force of the support spring is utilized to automatically regulate the flow of the fuel precipitate discharging valve is achieved, thus preventing fuel from overflowing.

Description

technical field [0001] The present invention relates to an aircraft fuel draining and sedimentation tool, more particularly, relates to a device for opening an aircraft fuel draining sedimentation valve and continuously draining fuel oil and sedimentation inside the left and right wing rectifying bulges. Background technique [0002] Usually, there are multiple sedimentation valves on the aircraft, which are respectively under the wing and inside the rectification drum. During ground maintenance, the sedimentation valve needs to be opened to discharge the sedimentation oil. [0003] For the sedimentation valve inside the rectification drum of the aircraft wing, the general ground crew will first open the maintenance flaps on the left and right wing rectification drums, enter the interior of the rectification drum, and then lift the fuel discharge sedimentation tool by hand and open the fuel discharge sedimentation valve , in order to carry out the fuel discharge sedimentatio...
