Abstract
A kind of reflecting surface pull-down of inflating expanded parabolic-cylinder antenna launches shaping mechanism, belong to satellite antenna technical field, the shaping device that has solved the reflecting surface employing of current gas-filled unfolded parabolic-cylinder antenna causes the problem that antenna overall weight is large, and it comprises flexible reflecting surface, carbon fiber side plate, aramid fiber granny rag, inflating expanded support ring, tracheae and carbon fiber support bar; At the upper surface of flexible reflecting surface and lower surface a carbon fiber side plate is each side set; At two carbon fiber side plate downsides that are positioned at flexible reflecting surface lower surface, an aramid fiber granny rag is respectively set, the top edge of aramid fiber granny rag is parabolic shape, in the inside and outside both sides of every aramid fiber granny rag, the inflating expanded support ring of multiple arcs is set, the multiple inflating expanded support ring that is positioned at the inside and outside both sides of every aramid fiber granny rag is communicated with head and the tail successively by tracheae; Between two blocks of carbon fiber side plates of flexible reflecting surface upper surface, connect by many carbon fiber support bars. The present invention's flexible reflecting surface that is used for formalizing.
Description
Technical field
The invention belongs to satellite antenna technical field, the reflecting surface pull-down that is specifically related to a kind of inflating expanded parabolic-cylinder antenna launches shaping mechanism.
Background technology
The reflecting surface of inflating expanded parabolic-cylinder antenna is to adopt flexible material, can curlingly fold, volume after folding is little, be convenient to delivery, inflating expanded with gas tube when use, by shaping device solid shape, form parabolic shape, the shaping device that the reflecting surface of current gas-filled unfolded parabolic-cylinder antenna adopts all comprises the heavier structures such as metal, causes antenna overall weight large, has increased delivery burden.
Summary of the invention
The shaping device that the object of the invention is the reflecting surface employing in order to solve current gas-filled unfolded parabolic-cylinder antenna causes the problem that antenna overall weight is large, provide a kind of reflecting surface pull-down of inflating expanded parabolic-cylinder antenna to launch shaping mechanism, its technical scheme is as follows:
The reflecting surface pull-down of inflating expanded parabolic-cylinder antenna launches a shaping mechanism, and it comprises flexible reflecting surface, carbon fiber side plate, aramid fiber granny rag, inflating expanded support ring, tracheae and carbon fiber support bar, the upper surface of flexible reflecting surface and lower surface a carbon fiber side plate is each side set, carbon fiber side plate and flexible reflecting surface are bonding, at two carbon fiber side plate downsides that are positioned at flexible reflecting surface lower surface, an aramid fiber granny rag is respectively set, the top edge of aramid fiber granny rag is parabolic shape, the top edge of aramid fiber granny rag is bonding with corresponding carbon fiber side plate, in the inside and outside both sides of every aramid fiber granny rag, the inflating expanded support ring of multiple arcs is set, the multiple inflating expanded support ring of the every inside and outside both sides of aramid fiber granny rag is crisscross arranged, the two ends of each inflating expanded support ring are bonding with corresponding carbon fiber side plate, side and aramid fiber granny rag that each inflating expanded support ring is relative with aramid fiber granny rag are bonding, the multiple inflating expanded support ring that is positioned at the inside and outside both sides of every aramid fiber granny rag is communicated with head and the tail successively by tracheae, between two blocks of carbon fiber side plates of flexible reflecting surface upper surface, connect by many carbon fiber support bars.
Beneficial effect of the present invention is: utilize aramid fiber granny rag and the inflating expanded support ring flexible reflecting surface that formalizes, setting accurately, lightweight, can curlingly fold, and volume after folding is less, the delivery of being more convenient for.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention:
See figures.1.and.2, a kind of reflecting surface pull-down of inflating expanded parabolic-cylinder antenna launches shaping mechanism, and it comprises flexible reflecting surface 1, carbon fiber side plate 2, aramid fiber granny rag 3, inflating expanded support ring 4, tracheae 5 and carbon fiber support bar 6, the upper surface of flexible reflecting surface 1 and lower surface a carbon fiber side plate 2 is each side set, carbon fiber side plate 2 is bonding with flexible reflecting surface 1, at two carbon fiber side plate 2 downsides that are positioned at flexible reflecting surface 1 lower surface, an aramid fiber granny rag 3 is respectively set, the top edge of aramid fiber granny rag 3 is parabolic shape, the top edge of aramid fiber granny rag 3 is bonding with corresponding carbon fiber side plate 2, the inflating expanded support ring 4 of multiple arcs is set in the inside and outside both sides of every aramid fiber granny rag 3, the multiple inflating expanded support ring 4 of every aramid fiber granny rag 3 inside and outside both sides is crisscross arranged, the two ends of each inflating expanded support ring 4 are bonding with corresponding carbon fiber side plate 2, side and aramid fiber granny rag 3 that each inflating expanded support ring 4 is relative with aramid fiber granny rag 3 are bonding, the multiple inflating expanded support ring 4 that is positioned at every aramid fiber granny rag 3 inside and outside both sides is communicated with head and the tail successively by tracheae 5, between two blocks of carbon fiber side plates 2 of flexible reflecting surface 1 upper surface, connect by many carbon fiber support bars 6.
The principle of invention: the carbon fiber side plate 2 of flexible reflecting surface 1 both sides accurately formalizes by aramid fiber granny rag 3 and inflating expanded support ring 4, thereby the shape of having fixed flexible reflecting surface 1, just can be overall curling folding after inflating expanded support ring 4 venting, is convenient to delivery.
