Problems solved by technology

Only the waterproof structure in the opening area of ​​the side wall cover cannot completely prevent the infiltration of rainwater. Once the leaking water enters the fuselage, it is easy to cause corrosion to the internal structure of the aircraft, and then destroy the structure, reduce the carrying capacity of the aircraft, and damage the electronic components of the aircraft. The equipment is in normal use

Embodiment Construction

[0016] The water storage tank [1] is arranged at the lower part of the side wall opening structure, the water storage tank is a semi-closed structure, and a hole is opened at its lowest point, the gasket [2] and the joint seat [3] are connected to the water storage tank [1] through bolts, and the drainage is soft. Tighten the pipe [5] on the joint seat [3], and fix the connection between the drain hose [5] and the joint seat with the clamp [4], and connect the rest of the drain hose [5] to the plane with the clamp [4]. The structure is fixed. In order to ensure the sealing of the drainage structure, use the sealant [6] to seal the connection gap between the water tank [1] and the joint seat [3].

[0017] The lower part of the joint seat [3] is designed into a stepped shape, which increases friction when the drainage hose [5] is tightened, and prevents water from seeping out. In addition, the drainage hose [5] is made of rubber material, which has strong bendability on the bas...

Abstract

The invention relates to the field of aircraft structural design, in particular to a drainage structure for a side wall mouth cover. The drainage structure comprises a water tank, a joint seat, clamps, a drain hose, and a sealant. The water tank is arranged under the opening of a side wall mouth cover; the joint seat is fixedly connected with the water tank by a bolt; the drain hose and the jointseat are screwed; the clamps enable the drain hose end and the drain hose to be fixed with the body; and slits between the water tank and the body and the joint seat are sealed by the sealant. The structure has advantages of simpleness, light weight, high processability, great easiness in production and assembling, great convenience in dismounting, long service life, and high reliability and the like and can be applied to various planes with high universality.

Description

technical field [0001] The invention relates to the field of aircraft structure design, in particular to a drainage structure for a side wall port cover. Background technique [0002] The side wall cover is mainly equipped with waterproof structures, such as rain strips, gaskets, etc. Due to the inherent defects of the structural surface, it is difficult to completely eliminate the leakage of rainwater. As a supplementary measure of the waterproof structure, the drainage structure can form a complete waterproof and drainage measure for the side wall of the aircraft, ensuring that the leakage water in the opening area of ​​the side wall will not directly flow into the interior of the aircraft. Only the waterproof structure in the opening area of ​​the side wall cover cannot completely prevent the infiltration of rainwater. Once the leaking water enters the fuselage, it is easy to cause corrosion to the internal structure of the aircraft, and then destroy the structure, reduce...
