Abstract
The utility model discloses a kind of lid discharge structure, comprise lid (1), mouth frame (4), sealing gasket (3) and rhone (7), described sealing gasket (3) is arranged in the gap that described lid (1) and mouth frame (4) cover place, play waterproof sealing effect, described rhone (7) is positioned at below the joint close of a mouthful frame (4) and lid (1), also comprise one group of drainage system, described drainage system comprises water fender (2) and water bar (5), described water fender (2) stretches out from lid (1) and extends to rhone (7) direction, most terminal in the vertical direction does not exceed rhone (7) extension, described water bar (5) stretches out from mouth frame (4) and extends to rhone (7) direction.The utility model can solve the large lid region occurred in groups and leak water problem, and assembling and positioning is simple and version is simple and reliable, can not reduce the intensity of original structure.
Description
Technical field
The utility model belongs to aeroplane structure design, relates to a kind of lid discharge structure.
Background technology
In the rhone used at present, without drainage system, if water bead interior surface or mouth frame inwall enter interior of aircraft, then the flow direction of uncontrollable water, and the water spilt in rhone cannot be collected, can the equipment on aircraft be caused damage for a long time.And the in-line rhone of the many employings of prior art is connected directly between on the web of frame, beam, not easily locates during assembling.Ponding is flowed by the difference of height of rhone, if assemble improper, ponding can overflow from rhone.Because tandem rhone is not have a closed rhone under each lid, rhone is crossing frame or Liang Shixu structurally carries out perforate, reduces the intensity of structure to a certain extent.This rhone reserve construction space need to the securing member of docking by structure cross docking area, then cannot receive leaking near cross docking area.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of structure that can solve the large lid region that occurs in groups and leak, assembling and positioning is simple and version is simple and reliable, can not reduce the intensity of original structure.
In order to solve the problem, technical solutions of the utility model provide. a kind of lid discharge structure, comprise lid 1, mouth frame 4, sealing gasket 3 and rhone 7, described sealing gasket 3 is arranged in the gap that described lid 1 and mouth frame 4 cover place, play waterproof sealing effect, described rhone 7 is positioned at below the joint close of mouthful frame 4 and lid 1, it is characterized in that, also comprise one group of drainage system, described drainage system comprises water fender 2 and water bar 5, described water fender 2 stretches out from lid 1 and extends to rhone 7 direction, most terminal in the vertical direction does not exceed rhone 7 extension, described water bar 5 stretches out from mouth frame 4 and extends to rhone 7 direction.
Preferably, the joint face of described 5 water bars and mouth frame 4 is zigzag, reserves the bonding pad that mouthful frame 4 is locked with lid.
Preferably, described rhone 7 is connected on mouthful frame 4 removably by connecting gusset plate.
Preferably, described rhone 7 is closed hoop structure, arranges osculum in the least significant end of rhone, and described osculum connects discharge pipe line.
Drainage system in the utility model, comprises water fender and water bar, the water entered in aircraft effectively can be imported in rhone, and prevent spilling of draining trough inner water.Lid border leak and lid locking nail hole leaks and all can be caught by garland, in time water is discharged.The water fender connected in lid border can improve lid border rigidity, and the installation of rhone can not have impact to original structural strength.The fillet design of lid and the layout of rhone reserve construction space can to structure cross docking area.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail, wherein:
Fig. 1 is a kind of lid draining junction structure;
Fig. 2 is lid and water fender;
Fig. 3 is water bar;
Fig. 4 garland, connection gusset plate and discharge pipe line.
Detailed description of the invention
Below the utility model is described in further details:
A kind of lid discharge structure, is made up of, as Fig. 1 lid 1, water fender 2, sealing gasket 3, mouth frame 4, water bar 5, connection gusset plate 6, rhone 7.
Described lid 1 is metal dots weld bond lid, and lid corner is designed to fillet, facilitates rhone shaping in the manufacture of corner.Water fender 2 can be linked together by spot welding, as Fig. 2 with lid 1; Sealing gasket 3 can use the silicone rubber seal gasket that resilience is higher.Water bar 5 is arranged on the below of mouthful frame 4, uses countersunk fastener with the connection of mouth frame 4, and water bar 5 and mouth frame bonding pad are designed to zigzag, reserves the bonding pad of lid lock and mouth frame, as shown in Figure 3.Need ensure during installing port cover lock that lockhole is within the scope of rhone, can be caught by rhone to ensure that lockhole leaks.
In order to reduce production cost, rhone 7 can adopt segmented, and segmentation place uses the docking of grooved interfacing part, and does binding face sealing, and joint securing member adopts wet connection.Because the space connected between gusset plate 6 and mouth frame web is less, connect gusset plate 6 and adopt rivet interlacement with rhone 7.Connecting gusset plate 6 uses plate nut to be connected with bolt with mouth frame 4, facilitates maintenance and the replacing of rhone.As shown in Figure 4, to begin to rehearse water hole in the minimum point of rhone 7, discharge pipe line 8 is welded with rhone 7, rhone internal water accumulation is discharged outside body by pipeline.
Claims (4)
1. a lid discharge structure, comprise lid (1), mouth frame (4), sealing gasket (3) and rhone (7), described sealing gasket (3) is arranged in the gap that described lid (1) and mouth frame (4) cover place, play waterproof sealing effect, described rhone (7) is positioned at below the joint close of a mouthful frame (4) and lid (1), it is characterized in that, also comprise one group of drainage system, described drainage system comprises water fender (2) and water bar (5), described water fender (2) stretches out from lid (1) and extends to rhone (7) direction, most terminal in the vertical direction does not exceed rhone (7) extension, described water bar (5) stretches out from mouth frame (4) and extends to rhone (7) direction.
2. discharge structure according to claim 1, is characterized in that, the joint face of described (5) water bar and mouth frame (4) is zigzag, reserves the bonding pad that a mouthful frame (4) is locked with lid.
