Description

Technical Field

[0001] This utility model relates to the field of removing foreign matter remaining during the riveting and drilling process inside the aircraft cabin, specifically to a special aircraft cabin foreign matter removal device. Background Technology

[0002] Aircraft cabins have complex structures and numerous ducts. During the processes of drilling and riveting the cabin structure, a significant amount of debris, such as metal shavings, is left behind. To prevent these debris from accumulating inside the cabin and posing a significant safety hazard, it is essential to design a dedicated aircraft cabin debris removal device. Utility Model Content

[0003] To address the existing technical problems, this utility model provides a cabin debris removal device for aircraft, comprising an air suction pipe for adsorbing debris, an end of the air suction pipe connected to a debris collection bag, an air inlet pipe connected to the end of the air suction pipe away from the debris collection bag, and an air outlet of the air inlet pipe extending into the interior of the air suction pipe, with compressed air injected into the other end of the air inlet pipe.

[0004] A further embodiment is that the end of the suction tube near the waste collection bag is connected to a fixing clamp, and the suction tube is fixedly connected to the waste collection bag through the fixing clamp.

[0005] A further embodiment is that the outlet of the air inlet pipe is inserted into one-third of the inner diameter of the air intake pipe.

[0006] A further embodiment is that the end of the intake pipe away from the suction pipe is provided with a conversion connector, and the intake pipe is connected to the outlet of an external compressor through the conversion connector.

[0007] A further embodiment is that the outer wall of the end of the air inlet pipe away from the air intake pipe is fixedly connected to the outer wall of the end of the air intake pipe near the waste collection bag via a support pipe.

[0008] A further option is to have the end of the suction tube for drawing in excess material tilted downwards.

[0009] The beneficial effects of this utility model are:

[0010] This invention uses an external compressor to generate compressed air, which enters the intake pipe through a conversion connector. The outlet of the intake pipe is inserted to one-third of the inner diameter of the suction pipe. The compressed air enters the waste collection bag through the suction pipe, creating a negative pressure between the waste suction end of the suction pipe and the outlet of the intake pipe. This creates a suction force at the waste suction end of the suction pipe, drawing the waste in the compartment into the collection bag, thus completing the waste removal process.
