Description
Technical field
The invention belongs to satellite antenna technical field, be specifically related to a kind of inflated supporting pipe and mix with hinge to support and launch spaceborne parabolic-cylinder antenna.
Background technology
Parabolic-cylinder antenna can be used as the automatic beam scanning antennas of high-gain, current spaceborne parabolic-cylinder antenna is all mechanical structure, not only weight is large, and gathering volume before launching is also larger, limit the further increase (if because gathering size exceedes the size of launching pod, antenna cannot carry out loading and launch) of antenna aperture.Therefore, be badly in need of a kind of lightweight, draw the little spaceborne parabolic-cylinder antenna of expandable type of volume in.
Summary of the invention
The object of the invention is to solve current spaceborne parabolic-cylinder antenna weight large and draw bulky problem in, provide a kind of inflated supporting pipe and mix with hinge to support and launch spaceborne parabolic-cylinder antenna, its technical scheme is as follows:
A kind of inflated supporting pipe mixes with hinge to support and launches spaceborne parabolic-cylinder antenna, and it comprises hinge, stationary spindle, mandrel, ribs, inflated supporting pipe and flexible reflecting surface, described hinge has two, every root hinge is connected and composed by more piece chain link, the upside of two adjacent pitch chain joints is hinged, and auxiliary power spring is provided with in hinged place, the downside of two adjacent pitch chain joints is linked by elastic card and connects, the upper surface of hinge is parabolic shape, the rear end of two hinges is connected with the two ends of stationary spindle, the front end of two hinges is connected with the two ends of mandrel, many ribs are provided with between two hinges, stationary spindle is respectively connected by an inflated supporting pipe with the two ends of mandrel, the front and back dual-side of flexible reflecting surface is connected with stationary spindle and mandrel, the limit, the left and right sides of flexible reflecting surface is each with a chain connection, the left and right sides of flexible reflecting surface is connected to the upper surface inside edge place of corresponding hinge by suspension wire.
Beneficial effect of the present invention is: flexible reflecting surface is mixed to support with hinge by inflated supporting pipe and launches, not only lightweight, draw in volume little, and expansion reliability is high, structural stability good, ensure that the surface precision of flexible reflecting surface, improves the reflecting effect of wireless signal.
accompanying drawing illustrates:
Fig. 1 is Facad structure schematic diagram of the present invention;
Fig. 2 is structure schematic diagram of the present invention;
Fig. 3 be in the present invention chain link junction elastic card cramp out after schematic diagram.
embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of inflated supporting pipe mixes with hinge to support and launches spaceborne parabolic-cylinder antenna, and it comprises hinge 1, stationary spindle 2, mandrel 3, ribs 4, inflated supporting pipe 5 and flexible reflecting surface 6, described hinge 1 has two, every root hinge 1 is connected and composed by more piece chain link, the upside of two adjacent pitch chain joints is hinged, and auxiliary power spring 1-1 is provided with in hinged place, the downside of two adjacent pitch chain joints is connected by elastic force buckle 1-2, the upper surface of hinge 1 is parabolic shape, the rear end of two hinges 1 is connected with the two ends of stationary spindle 2, the front end of two hinges 1 is connected with the two ends of mandrel 3, many ribs 4 are provided with between two hinges 1, stationary spindle 2 is respectively connected by an inflated supporting pipe 5 with the two ends of mandrel 3, the front and back dual-side of flexible reflecting surface 6 is connected with stationary spindle 2 and mandrel 3, the limit, the left and right sides of flexible reflecting surface 6 is respectively connected with a hinge 1, the left and right sides of flexible reflecting surface 6 is connected to the upper surface inside edge place of corresponding hinge 1 by suspension wire 6-1.
Preferably, because described hinge 1 front end is stressed less, hinge 1 is gradually carefully arranged by rear end forward end, namely alleviates overall weight, turn reduces the volume after folding.
The using method of invention and principle: time folding, elastic force buckle 1-2 on the downside of each chain link is opened, fold by mandrel 3 one end, inflated supporting pipe 5, hinge 1, reflecting surface 6 etc. are twisted on mandrel 3; Stationary spindle 2 one end is connected with celestial body, inflate in inflated supporting pipe 5 when space development, under the supporting role of inflated supporting pipe 5, make hinge 1 drive flexible reflecting surface 6 to launch, auxiliary power spring 1-1 and elastic force buckle 1-2 can play the effect of stable hinge 1 after deployment.
