Embodiment
Reduction antenna house air drag is realized for the utility model is expanded on further, and good sealed environment is provided and is carried
The purpose of high antenna house reliability, with reference to the accompanying drawings and embodiments to specific embodiment of the present utility model, architectural feature
And its effect, describe in detail as follows.
A kind of hung outside helicopter arc encapsulated antenna cover, including antenna upper cover 1 and antenna lower cover 2, as shown in Figure 1, antenna
1 inner wall lower of upper cover is equipped with the ring packing raised step 4 radially extended to it, and 4 bottom surface of ring packing raised step is equipped with
The water proof flange 5 extended straight down；So that shape between the bottom surface of ring packing raised step 4 and the madial wall of water proof flange 5
Into the holding tank for accommodating the antenna lower cover 2；2 upper surface of antenna lower cover is equipped with annular water proof beam 6, the annular water proof beam 6
It is arranged concentrically with antenna lower cover 2, to ensure that a small amount of water for oozing gasket will not cross annular water proof beam 6 and enter in antenna house
Chamber, 4 side wall of ring packing raised step are contacted with annular 6 outer wall of water proof beam, and gasket 7 is equipped with holding tank；Gasket 7 is
L-shaped structure, its horizontal segment are bonded in 2 upper surface of antenna lower cover in the annular outside of water proof beam 6 by resin glue, and gasket 7 is vertical
Section is between 5 inner wall of lateral wall and water proof flange of antenna lower cover 2, and the lateral wall of 7 vertical section of gasket is equipped with multiple
Double wedge；The gasket 7 has decrement on vertical direction, also has decrement on horizontal direction, when upper lower cover passes through spiral shell
When nail tenses, 7 in the vertical direction of gasket is extruded, and so forms one of axial seal；The wherein lateral layout of gasket 7
For zigzag, when upper cover is pressed into lower cover, the gasket of side saw shape is equally also extruded, so shape again in radial directions
Into sealing together.Wherein zigzag design can ensure that upper cover is conveniently loaded lower cover, it is also ensured that in radial direction
On be not in that decrement is excessive, cause outer cover deform sign.
Further, as shown in Fig. 2, antenna upper cover 1 in the outer wall parallel to helicopter direction of advance is circular arc type, hanging down
It is round, the generally arc of antenna upper cover 1 on straight direction, while integrated antenna upper cover has the pattern draft of low-angle, this
The design of sample has light weight, and windage is small, handling ease；As shown in figure 3, antenna lower cover 2 is glass steel material, mounting base 3
For aluminum alloy material, mounting base 3 is embedded in inside antenna lower cover 2 to install satellite antenna so that the overall stress of antenna
On the mounting base 3 of aluminum alloy material, and antenna lower cover 2 only needs to support antenna upper cover 1, that is, ensure that the intensity of structure again
The weight of antenna house entirety can be reduced, wherein mounting hole all on mounting base 3 is blind hole, can so ensure the rain of outside
Water will not be penetrated into inside antenna house by screw.
Further, as shown in figure 4, further respectively having screw mouth 8 and waterproof vent valve 9 on 2 bottom surface of antenna lower cover, penetrating
Frequency air plug 10, data air plug 11 and power supply air plug interface 12, marine glue, wherein waterproof vent valve 9 are smeared after installation in interface
There is waterproof ventilated membrane in inside, can separate the intrusion of water, and can guarantee that the circulation of air, so when answering inside and outside antenna house pressure not
When consistent, external and internal pressure can be balanced.Preferably, waterproof vent valve 9 is designed with sealing ring with 2 installation place of antenna lower cover, prevents
Rainwater is invaded from mounting hole.
This antenna house is generally arc-shaped, can greatly reduce windage, reduces the kinetic energy loss of helicopter；And axial direction and footpath
To combined labyrinth and carbon gland, the sealing protection effect to hung outside helicopter antenna is effectively strengthened, water proof flange 5 has wrapped up gasket
7, result in formation of a circle guard circle, prevent the water in the external world to be directly impinging on 7 body of gasket, waterproof vent valve 9 can also
The reliability of this antenna house is effectively lifted on the premise of good water isolating is kept.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
