Abstract

The invention discloses an air inflation unfolding parabolic cylinder antenna reflecting surface, belongs to the technical field of air inflation unfolding antennas, and solves the problem that accuracy of a reflecting surface of an air inflation unfolding parabolic cylinder antenna is difficult to control after the air inflation unfolding parabolic cylinder antenna is unfolded. The air inflation unfolding parabolic cylinder antenna reflecting surface comprises a flexible reflecting surface and a carbon fiber backboard, wherein the flexible reflecting surface covers the surface of one side of the carbon fiber backboard, hollows are formed in the carbon fiber backboard, sizing rods are arranged at two ends of the carbon fiber backboard, a plurality of reinforcing ribs are arranged on the surface of the other side of the carbon fiber backboard, and pull ropes respectively connect two ends of each sizing rod together and two ends of each reinforcing rib together so as to fix the air inflation unfolding parabolic cylinder antenna reflecting surface. The air inflation unfolding parabolic cylinder antenna reflecting surface is used on the air inflation unfolding parabolic cylinder antenna.

Description

A kind of inflating expanded parabolic-cylinder antenna reflecting surface
Technical field
The invention belongs to inflating expanded antenna technical field, be specifically related to a kind of inflating expanded parabolic-cylinder antenna reflecting surface.
Background technology
The reflecting surface of inflating expanded parabolic-cylinder antenna is to adopt flexible material, can and the structure such as gas-filled tube together with curling folding, be convenient to deliver, inflating expanded with gas-filled tube when use, form default parabolic shape.
Because the reflecting surface of inflating expanded parabolic-cylinder antenna is to adopt flexible material, so in the more difficult control of precision that launches back reflection face, the method of taking is at present, in the both sides of flexible reflecting surface, carbon fiber board is set, again carbon fiber board is connected with gas-filled tube by stay cord, and by stay cord control reflector shape, in order to improve precision, nearly tens of stay cord quantity, very easily be wound around, impact launches.
Summary of the invention
The object of the invention is to launch back reflection surface accuracy problem more rambunctious in order to solve inflating expanded parabolic-cylinder antenna, a kind of inflating expanded parabolic-cylinder antenna reflecting surface is provided, its technical scheme is as follows:
A kind of inflating expanded parabolic-cylinder antenna reflecting surface, it comprises flexible reflecting surface and carbon fiber backboard, and described flexible reflecting surface is overlying on a side surface of carbon fiber backboard, on carbon fiber backboard, is provided with hollow out.
Beneficial effect of the present invention is: reverse side shape as required arranges the distribution of hollow out on carbon fiber backboard, and shape and the precision of the distribution control reflecting surface by hollow out reduce stay cord quantity, avoid being mutually wound around between stay cord.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic side view of the present invention;
Fig. 3 is the schematic diagram of carbon fiber backboard in the present invention.
embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of inflating expanded parabolic-cylinder antenna reflecting surface, it comprises flexible reflecting surface 1 and carbon fiber backboard 2, and described flexible reflecting surface 1 is overlying on a side surface of carbon fiber backboard 2, is provided with hollow out 2-1 on carbon fiber backboard 2.
Hollow out 2-1 on described carbon fiber backboard 2 is that multiple identical isosceles triangle shapes are arranged side by side with equidirectional; Be provided with sizing bar 3 at the two ends of carbon fiber backboard 2, sizing bar 3 is fixedly connected with carbon fiber backboard 2, on the opposite side surface of carbon fiber backboard 2, be provided with many ribs 4, ribs 4 adopts carbon fiber hollow tube, ribs 4 is fixedly connected with carbon fiber backboard 2, between sizing bar 3 and the two ends of ribs 4, connects sizing by stay cord 5.
Preferably, the sizing bar 3 of described carbon fiber backboard 2 one end is connected by stay cord 5 with the sizing bar 3 of every ribs 4 and carbon fiber backboard 2 other ends respectively.
The principle of invention: along with the variation of hollow out 2-1, the radian of carbon fiber backboard 2 changes thereupon, forms parabolic cylinder reflecting surface, and ribs 4 can play to carbon fiber backboard 2 mid portions the effect of sizing, improves reflector precision.
