Abstract
The utility model relates to the radar antenna base improving waterproof and breathable structure.Comprise base, pivoting support gear wheel, two travelling gears, rotating disk and two reductors; Its turntable is the oblate frustum that axially middle part is hollow, comprises inner cylinder, outer cylinder and securing cover plate; The sidewall of the inner cylinder of rotating disk is provided with threaded block, the sidewall of the through inner cylinder of threaded block; The external port of threaded block is provided with waterproof and breathable plug, and the inner port of threaded block is connected to one end of conduit, and the other end of conduit is communicated with the cover plate at the top of base; Thus ensure that the inner chamber of end base is communicated with air.Waterproof and breathable plug installation site of the present utility model, avoids and interferes possibility with radar other system; Ambient atmosphere forms connected component through waterproof and breathable plug, steel pipe etc. with non-oil pocket cavity, and ensure that can not because of draught head, and the lubricating oil of the oil pocket cavity in base can not enter into non-oil pocket cavity and leakage of oil oil impregnate phenomenon occurs.
Description
Technical field
The utility model belongs to Radar Antenna System field, be specifically related to a kind of waterproof and breathable structure of antenna pedestal of radar antenna, can ensure that the inner non-oil pocket cavity of radar antenna base and outside atmosphere communicate, thus oil leakage phenomenon can not be there is because atmospheric pressure difference enters non-oil cavity in gear lubricant.
Background technology
In the structure of radar antenna base, waterproof oil-leakage-prevention is one of difficult point of most critical always.After radar system has been set up, just need to ensure that radar antenna base can in long-term work in oil tight situation of can not intaking.Nowadays, do not design waterproof and breathable structure in the structure of some radar antenna bases, therefore, after radar antenna base long-time running, leakage of oil situation can occur; What adopt in the structure of some radar antenna bases is waterproof and breathable plug, but waterproof and breathable plug is arranged on above the stifle with holes of antenna pedestal.There is following defect in this kind of design: waterproof and breathable plug is arranged on antenna pedestal top, when assembling easily and radar other system interfere; The aesthetic property of impact design; Waterproof and breathable plug long term exposure, in outside, easily causes waterproof and breathable plug damage and cavity water inlet phenomenon occurs.
Utility model content
In order to make up the deficiency of prior art, the utility model provides a kind of radar antenna base improving waterproof and breathable structure.
Concrete improvement opportunity scheme is as follows:
The radar antenna base improving waterproof and breathable structure comprises base 1, pivoting support gear wheel 6, two travelling gears, rotating disk 7 and two reductors 2; Pivoting support gear wheel 6 and two travelling gears are all positioned at base 1, two travelling gears are arranged on the output shaft of two reductors 2 respectively, rotating disk 7 is fixedly connected the end face of the axial side of pivoting support gear wheel 6, two travelling gears, by the engaged transmission with pivoting support gear wheel 6, drive rotating disk 7 to rotate; Described rotating disk 7 is the oblate frustum that axially middle part is hollow, and comprise inner cylinder 10, outer cylinder and securing cover plate 9, the sidewall of the inner cylinder 10 of described rotating disk 7 is provided with threaded block 3, the sidewall of the through inner cylinder 10 of threaded block 3; The external port of threaded block 3 is provided with waterproof and breathable plug 4, and the inner port of threaded block 3 is connected to one end of conduit 5, and the other end of conduit 5 is communicated with the top blind flange 8 of base 1; Thus ensure that the inner chamber of end base 1 is communicated with air.
Advantageous Effects of the present utility model embodies in the following areas:
1. waterproof and breathable plug is arranged on the steel pipe Single port of the welding threaded block of inner cylinder, is designed beautifully, and ensures to interfere possibility with radar other system simultaneously; Ambient atmosphere forms connected component through waterproof and breathable plug, steel pipe etc. with non-oil pocket cavity, and ensure that can not because of draught head, and in base, the lubricating oil of oil pocket cavity can not enter into non-oil pocket cavity and leakage of oil oil impregnate phenomenon occurs;
2. there is securing cover plate above the installation site of waterproof and breathable plug, thus can not occur antenna pedestal water inlet phenomenon occurs due to the damage of waterproof and breathable plug.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is Fig. 2 structure A-A cutaway view.
Sequence number in upper figure: base 1, reductor 2, threaded block 3, waterproof and breathable plug 4, conduit 5, pivoting support gear wheel 6, rotating disk 7, cover plate 8, securing cover plate 9, inner cylinder 10.
Embodiment
Below in conjunction with accompanying drawing
The radar antenna base improving waterproof and breathable structure comprises base 1, pivoting support gear wheel 6, two travelling gears, rotating disk 7 and two reductors 2; Pivoting support gear wheel 6 and two travelling gears are all positioned at base 1, two travelling gears are arranged on the output shaft of two reductors 2 respectively, rotating disk 7 is fixedly connected the end face of the axial side of pivoting support gear wheel 6, two travelling gears, by the engaged transmission with pivoting support gear wheel 6, drive rotating disk 7 to rotate; Rotating disk 7 is the oblate frustum that axially middle part is hollow, comprises inner cylinder 10, outer cylinder and securing cover plate 9.The sidewall of the inner cylinder 10 of rotating disk 7 is provided with threaded block 3, the sidewall of the through inner cylinder 10 of threaded block 3; The external port of threaded block 3 is provided with waterproof and breathable plug 4, and the inner port of threaded block 3 is connected to one end of conduit 5, and the other end of conduit 5 is communicated with the cover plate 8 at the top of base 1; Conduit 5 is steel pipe, and caliber is 12mm.Waterproof and breathable plug 4 is positioned at the axially middle part hollow position of rotating disk 7, avoids the problem interfered with radar other system; Waterproof and breathable plug 4, for having waterproof effect and keeping the stopper of high Air permenbility, on the one hand, avoids the generation of antenna pedestal water inlet problem, on the other hand, ensure that the inner chamber of base 1 is communicated with air.
