Telescopic fuel precipitating tool

Abstract

Disclosed is a telescopic tool for fuel oil precipitate discharge, comprising an initiating apparatus, a collecting bowl (3), a telescopic rod and a locking device (10) and a sheet iron bucket with a magnetic base (12). Use of the telescopic tool for fuel oil precipitate discharge enables a fuel oil precipitate discharge valve on an aircraft to be opened and the precipitate discharged from the precipitate discharge valve to be collected and guided into the underlying sheet iron bucket. The telescopic rod is composed of inner and outer sleeved rods, connected by the locking device (10). When the locking device is unlocked, the inner sleeved rod (8) slides in the outer sleeved rod (9), and when the locking device is locked, the inner sleeved rod expands to be locked within the outer sleeved rod in any position. The fuel tank precipitate discharge apparatus has the function of a high degree of freedom of adjustment, can be adapted to the requirements of wings of different heights, and can accomplish fuel oil precipitate discharge without requiring manual lifting.

Description

technical field [0001] The invention relates to an aircraft fuel tank settling device, in particular, the invention relates to a highly scalable aircraft fuel tank settling device. Background technique [0002] There are multiple sedimentation valves on the aircraft, which are located in different parts under the wing fuel tank of the aircraft. During ground maintenance, the sedimentation valves need to be opened to discharge the sedimentation oil. In the existing aircraft structure, some aircraft can hang the suspension point of the sedimentation tool on the sedimentation valve and the aircraft structure, so that when the aircraft sedimentation operation is required, the corresponding sedimentation device only needs to be hung on the suspension point That's it. [0003] However, the design of the aircraft structure needs to be considered as a whole, especially the aerodynamic characteristics of the aircraft. Therefore, there are no suspension points on the structure of som...

Problems solved by technology

[0003] However, the design of the aircraft structure needs to be considered as a whole, especially the aerodynamic characteristics of the aircraft. Therefore, there are no suspension points on the structure of some aircraft. At this time, the operator needs to lift the sedimentation tool manually to operate

However, the sedimentation valve under the wing is generally a certain distance from the ground, and since the height of the buffer pillar of the landing gear of the aircraft is related to the weight of the aircraft, when the weight of the aircraft is different, the distance from the ground to the sedimentation valve under the wing also changes. In this way, it is necessary to be equipped with sedimentation tools of different lengths.

[0004] like Figure 5 As shown, in the prior art, a settling device connected by multi-section fixed-length connecting rods is provided. Although the device can reduce the number of equipped settling tools, but because the multi-section fixed-length connecting rods are connected , so its length is not arbitrarily adjustable

[0005] In addition, in the prior art, the maintenance personnel have to push the tool for a long time during the sedimentation operation, which is very inconvenient
