Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aircraft fuel discharge, in particular to a tool for discharging aircraft fuel sediment. Background Art
[0002] Fuel sediment will be produced in the fuel tank of the aircraft. The main component of fuel sediment is water. Water enters the fuel tank through impurities in the fuel and condensation of moist air. Water is deposited in the fuel tank, causing microorganisms to grow, which will cause microbial corrosion in the fuel tank and damage the fuel tank structure. Because the density of water is greater than that of fuel, water will be deposited at the lowest point of the fuel tank, so the fuel tank drain valve is installed on the lower surface of the wing, corresponding to the lowest point of each fuel tank.
[0003] A Chinese patent with publication number CN207809811U was searched and disclosed, which is a tool for discharging aircraft fuel sediment. The length of the extension tube can be flexibly adjusted according to the height of the aircraft fuel tank; a support frame is used to fix the bottom of the extension tube to the ground, so that one operator can complete the work of discharging aircraft fuel sediment, which greatly facilitates the operation; a rain shield is provided at the bottom end of the extension tube, which can protect the oil bottle mouth that receives the fuel sediment to prevent rainwater from entering and affecting the next step of analyzing the fuel sediment.
[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The drain valve is opened by the top of the top head, and the fuel sediment is collected in conjunction with the adsorption section. However, the line of sight is easily blocked by the adsorption section during the alignment of the top head and the drain valve, which makes it difficult to align with the drain valve, and the structural connectivity is poor. The shape of the adsorption section is not convenient for collecting fuel sediment, which reduces the discharge efficiency of aircraft fuel sediment. Utility Model Content
