Description
Technical field:
The invention belongs to the inflating expanded parabolic antenna technical field of fin-plate type, be specifically related to the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type.
Background technology:
The inflating expanded parabolic antenna of fin-plate type has widespread demand at numerous areas, as electronic reconnaissance, navigation, communication, ground prospecting satellite etc.
The structure of inflatable space antenna, can FOLD AND PACK expeditiously before inflation based on flexible material, has delivery volume little, lightweight and launch the high advantage of reliability.Large-scale inflatable space antenna is launched enters the orbit, inflating expanded and after rigidifying, can form large space antenna, and inflatable space antenna is the effective way not solving large space antenna structure.
For the inflating expanded parabolic antenna of fin-plate type, not yet there is effective loader mechanism at present, in antenna transmission process, packaging cannot be carried out to each structure member of antenna to compress, make each structure member of antenna vibrate under the effect of launching shock power, collide, cause structural failure.
Summary of the invention:
The object of the invention is to solve for the inflating expanded parabolic antenna of fin-plate type, not yet have the problem of effective loader mechanism at present, provide the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type, its technical scheme is as follows:
A loader mechanism for the inflating expanded parabolic antenna of fin-plate type, it comprises upper press cover and lower cover; Described upper press cover is surrounded by more blades and is connected and composed by connector, upper end and the connector of each blade are rotationally connected by spring hinge, each blade is expanded to shrink for axle with the link of connector and hinge and is rotated, connector is provided with connecting screw hole, the lower end of each blade curves inwardly setting, and its angle that curves inwardly is less than 90 degree; Described lower cover comprises pressure wall, spring and pocket wall, spring is arranged on pressure wall upper surface, and pocket wall is arranged on pressure wall lower end, and pressure wall and spring are arranged on inside upper press cover, the lower end of the lower end of upper press cover and each blade catches by pocket wall, and the shape of pocket wall and upper press cover lower end coincide.
Beneficial effect of the present invention is: can the inflating expanded parabolic antenna of fin-plate type of doubling poststack carry out compressing and packing, avoid in antenna transmission process, each structure member vibrates, collides under the effect of launching shock power, cause structural failure, the transmitting that guarantee paraballon can be safe and reliable also launches.

Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type, it comprises upper press cover 1 and lower cover 2; Described upper press cover 1 is surrounded by more blades 1-1 and is connected and composed by connector 1-2, upper end and the connector 1-2 of each blade 1-1 are rotationally connected by spring hinge 1-3, each blade 1-1 expands to shrink for axle with the link of connector 1-2 and hinge 1-3 and rotates, connector 1-2 is provided with connecting screw hole 1-2-1, the lower end of each blade 1-1 curves inwardly setting, and its angle that curves inwardly is less than 90 degree; Described lower cover 2 comprises pressure wall 2-1, spring 2-2 and pocket wall 2-3, spring 2-2 is arranged on pressure wall 2-1 upper surface, pocket wall 2-3 is arranged on pressure wall 2-1 lower end, pressure wall 2-1 and spring 2-2 is arranged on inside upper press cover 1, the lower end of the lower end of upper press cover 1 and each blade 1-1 catches by pocket wall 2-3, and the shape of pocket wall 2-3 and upper press cover 1 lower end coincide.
Preferably, the lower end of each blade 1-1 of described upper press cover 1 angle that curves inwardly is 45 degree.
The using method of invention and principle: first the inflating expanded parabolic antenna of fin-plate type after curling folding is enclosed within lower cover 2, the spring 2-2 upper end of lower cover 2 is against the lower surface of central dram, surround downwards with each blade 1-1 of upper press cover 1 again, be enclosed within outside the inflating expanded parabolic antenna of fin-plate type after curling folding, and side compression in the pocket wall 2-3 lower end of each blade 1-1 being placed on lower cover 2, the inflating expanded parabolic antenna of fin-plate type after by curling folding now is needed to compress, spring 2-2 is also needed to compress downwards, then by screw, the connector 1-2 of upper press cover 1 is connected with the central dram of the inflating expanded parabolic antenna of fin-plate type after curling folding at connecting screw hole 1-2-1 place, blasting bolt is finally used the central dram of lower cover 2 with the inflating expanded parabolic antenna of fin-plate type after curling folding to be connected, curling folding after the inflating expanded parabolic antenna of fin-plate type to be loaded in the space that formed between upper press cover 1 and lower cover 2 and compacted.
Before needing to launch the inflating expanded parabolic antenna of fin-plate type, only need to ignite blasting bolt, lower cover 2 can be flicked by spring 2-2, after lower cover 2 is flicked, blade 1-1 upwards launches under the elastic force of spring hinge 1-3, and the inflating expanded parabolic antenna of fin-plate type just can carry out inflating expanded operation of Denging.
