Abstract

The invention provides a loading mechanism of a ribbed plate type inflatable unfolding parabolic antenna, and belongs to the technical field of the ribbed plate type inflatable unfolding parabolic antenna. The problem that at present, an effective loading mechanism does not exist for the ribbed plate type inflatable unfolding parabolic antenna is solved. The loading mechanism of the ribbed plate type inflatable unfolding parabolic antenna comprises an upper gland and a lower gland, the upper gland is defined by a plurality of vanes through a connecting piece, the upper end of each vane is in rotating connection with the connecting piece through a spring hinge, connecting screw holes are formed in the connecting piece, the lower end of each vane is arranged to be bent inwards, and the inward bending angle is smaller than 90 degrees. The lower gland comprises a pressing wall, a spring and a wrapping wall, the spring is arranged on the upper end face of the pressing wall, the wrapping wall is arranged at the lower end of the pressing wall, the pressing wall and the spring are arranged on the inner side of the upper gland, the wrapping wall enables the lower end of the upper gland, namely the lower ends of all the vanes to be wrapped, and the shape of the wrapping wall is matched with the lower end of the upper gland. The loading mechanism of the ribbed plate type inflatable unfolding parabolic antenna is used for loading the curly-folded ribbed plate type inflatable unfolding parabolic antenna.

Description

Technical field: [0001] The invention belongs to the technical field of rib-plate type inflatable and unfolded parabolic antennas, and in particular relates to a loading mechanism for rib-plate type inflatable and unfolded paraboloid antennas. Background technique: [0002] The rib-type inflatable deployable parabolic antenna has a wide demand in many fields, such as electronic reconnaissance, navigation, communication, and ground survey satellites. [0003] The structure of the inflatable deployable antenna is mainly made of flexible materials, which can be folded and packaged efficiently before inflation, and has the advantages of small carrying volume, light weight and high deployment reliability. The large-scale inflatable deployment antenna is launched into orbit, and after inflation and rigidification, a large-scale space antenna can be formed. The inflatable deployment antenna is an effective way to solve the structure of large-scale space antennas in the future. [...
