Abstract
The utility model relates to a drainage structure of an airplane cabin door. The drainage structure comprises a water accumulating tank, a funnel component and a sealing plug, wherein the water accumulating tank is fixed between the passenger cabin floor of an airplane and an airplane sidewall structure at the cabin door, and a leakage hole is formed in the bottom of the water accumulating tank; the funnel component is mounted at the leakage hole, and a leakage pipe at the lower end of the funnel component extends out of fuselage skin; the sealing plug is tapered and is matched with the taper hole of the funnel component, and the sealing plug is fixed on the airplane sidewall structure through a chain.
Description
Technical field
The present invention relates to the design field technology of aircraft, particularly the discharge structure of aircraft door.
Background technology
Aircraft door is while passing in and out aircraft cabin for crew, passenger or goods, hatch door is when routine use, run into and while raining, open in hatch door or the aging situation of hatch door sealing band, from the just easy rain of hatch door, enter in the cabin of aircraft, the ponding entering in cabin must have measure to guarantee to discharge out of my cabin, therefore when aircraft door designs, just must consider drainage problem.
In prior art, the drainage problem of hatch door is there are no special design, to the ponding of interior of aircraft, take leaking hole processed on underbelly covering to discharge with installation draining valve, these drainage measures are arranged in the nadir of underbelly, when fuselage airtight cabin is during in atmospheric pressure state, valve is opened to discharge ponding; When airtight cabin is during in pressurized state, draining valve closes to guarantee that fuselage is airtight automatically.
The ponding at aircraft door place is due to the high nadir that cannot directly arrive underbelly in position, ponding can not be discharged out of my cabin by these leaking holes and draining valve, easily aircaft configuration is produced to corrosion, thereby affect normal use and the life-span of aircraft, the discharge structure that therefore designs a kind of aircraft door is directly discharged aircraft outside by ponding and is just seemed very necessary.
Summary of the invention
The problem existing in order to solve prior art, the application's object is to design a kind of discharge structure of aircraft door, to solve the ponding that current aircraft door position exists and the normal use problem that affects aircraft.
A kind of discharge structure of aircraft door, contain water storage tank, funnel assemblies and sealing plug, it is characterized in that described water storage tank be one with the elongated slot structure of flank, be fixed between the floor level of aircraft and the aircraft side wall construction at hatch door place, a flank of water storage tank is horizontal, fixed on the floor level of aircraft, another flank of water storage tank is fixed in the aircraft side wall construction at hatch door place, the bottom land of water storage tank is shaped with leaking hole, described funnel assemblies is arranged on this leaking hole place, the coniform hole edge of the upper end of funnel assemblies and the water storage tank body of leaking hole periphery are tightly connected, the pipe that leaks of funnel assemblies lower end stretches out outside fuselage skin, sealing plug is that taper is mated with the taper hole of funnel assemblies, sealing plug is fixed in aircraft side wall construction by chain.
The application has the following advantages: 1) funnel assemblies is positioned at the bottom of water storage tank, its surface is lower than aircraft floor, aircraft sealing plug when normal flight or daily parking is inlaid in the coniform hole of funnel assemblies, guarantee that aircraft is air tight when pressurized state, while having ponding in water storage tank, open sealing plug, ponding will be discharged airframe by funnel assemblies.When having solved hatch door place ponding problem, guaranteed the air-tightness of aircraft.2) simple in structure, can be intuitively, fast, timely the ponding at hatch door place is discharged to fuselage outside.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail:
Accompanying drawing explanation
The signal of Fig. 1 hatch door discharge structure position
Section signal during the not draining of Fig. 2 hatch door discharge structure
Section signal during the draining of Fig. 3 hatch door discharge structure
Numbering signal in figure: 1 water storage tank, 2 sealing plugs, 3 funnel assemblies, 4 leaking holes, 5 fuselage skins, 6 chains, 7 hatch doors, 8 floor levels, 9 side wall constructions, 10
The specific embodiment
Referring to accompanying drawing, a kind of discharge structure of aircraft door, contain water storage tank 1, funnel assemblies 3 and sealing plug 2, water storage tank 1 be one with the elongated slot structure of flank, be fixed between the floor level 8 of aircraft and the aircraft side wall construction 9 at hatch door place, a flank of water storage tank 1 is horizontal, fixed on the floor level 8 of aircraft, another flank of water storage tank 1 is fixed in the aircraft side wall construction 9 at hatch door place, the bottom land of water storage tank 1 is shaped with leaking hole 4, described funnel assemblies 3 is arranged on this leaking hole 4 places, the water storage tank body of the coniform hole edge of the upper end of funnel assemblies 3 and leaking hole 4 peripheries is tightly connected, the pipe that leaks of funnel assemblies lower end stretches out outside fuselage skin 5, sealing plug 2 mates with the taper hole of funnel assemblies for taper, sealing plug 2 is fixed in aircraft side wall construction by chain 6.
Aircraft sealing plug 2 when normal flight or daily parking is arranged in the coniform hole of funnel assemblies 3, guarantees that aircraft is air tight when pressurized state.Rainwater enters cabin from hatch door 7 and flows into after water storage tank 1, extracts tapered sealing plug 2, and rainwater can flow into the taper hole of funnel assemblies 3 along the leaking hole of water storage tank 1, by taper hole, ponding is discharged to fuselage skin 5 outsides.
