Description
Technical field
The invention belongs to the inflating expanded parabolic antenna technical field of fin-plate type, the elastic force constraint being specifically related to the inflating expanded parabolic antenna of a kind of fin-plate type launches controlling organization.
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.
The expansion of the inflating expanded parabolic antenna of fin-plate type and supporting construction are formed primarily of inflation ring and radial rib plate combination, and in expansion process, the blowing pressure drives inflation ring to launch and drives radial rib plate and total to launch shaping.Inflation ring and radial rib plate adopt flexible composite manufacture, cannot control effectively to its expansion process at present, in expansion process, especially at the inflating expanded initial stage, inflation ring pressure is lower, and floor does not launch completely, now inflation ring and floor so that whole reflecting surface structure rigidity all very low, be difficult to ensure that whole reflecting surface can according to desirable expansion order, path and speed are launched, and easily cause floor and inflation ring to produce being wound around, collision, even can produce larger impact and disturbance to spacecraft, reduce spacecraft safety and reliability in orbit.
Summary of the invention
The object of the invention is to solve the inflating expanded parabolic antenna of fin-plate type, the problem that cannot control effectively to its expansion process at present, the elastic force constraint providing the inflating expanded parabolic antenna of a kind of fin-plate type launches controlling organization, and its technical scheme is as follows:
The elastic force constraint of the inflating expanded parabolic antenna of fin-plate type launches a controlling organization, and it comprises fixed disc, support rail, floor depression bar and extension spring; Around described fixed disc, multiple support rail is set, support rail is fixedly connected with fixed disc or integrally formed structure, the downward-sloping setting in outer end of support rail, limiting plate is provided with on support rail, fixed disc is provided with multiple connecting screw hole, the outer end of support rail is rotationally connected by the upper end of rotating shaft and floor depression bar, and support rail is also connected with floor depression bar by extension spring, and extension spring is arranged on the side of support rail and floor depression bar.
Beneficial effect of the present invention is: control effectively to the expansion process of the inflating expanded parabolic antenna of fin-plate type, can launch according to desirable expansion order, path and speed, and avoid floor and inflation ring to produce being wound around, collide, even can produce larger impact and disturbance to spacecraft, improve spacecraft safety and reliability in orbit.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram after the floor depression bar in the present invention turns over.
embodiment:
See figures.1.and.2, the elastic force constraint of the inflating expanded parabolic antenna of a kind of fin-plate type launches controlling organization, and it comprises fixed disc 1, support rail 2, floor depression bar 3 and extension spring 4; Around described fixed disc 1, multiple support rail 2 is set, support rail 2 is fixedly connected with or integrally formed structure with fixed disc 1, the downward-sloping setting in outer end of support rail 2, limiting plate 2-1 is provided with on support rail 2, fixed disc 1 is provided with multiple connecting screw hole 2-2, the outer end of support rail 2 is rotationally connected by the upper end of rotating shaft 2-3 and floor depression bar 3, support rail 2 is also connected with floor depression bar 3 by extension spring 4, and extension spring 4 is arranged on the side of support rail 2 and floor depression bar 3.
The length of described floor depression bar 3 is arranged according to the height of the inflating expanded parabolic antenna of fin-plate type after curling folding and floor width, being pressed in bottom on outmost turns floor of the rear floor depression bar 3 of installation, and distance base 1/1 to two/5th place being positioned at floor width.
Preferably, the length of described floor depression bar 3 is arranged according to the height of the inflating expanded parabolic antenna of fin-plate type after curling folding and floor width, being pressed in bottom on outmost turns floor of the rear floor depression bar 3 of installation, and distance base 1/4th place being positioned at floor width.
The using method of invention and principle: by curling folding after the central dram of the inflating expanded parabolic antenna of fin-plate type be arranged on fixed disc 1 and be bolted below, floor depression bar 3 lower end is pressed in the outmost turns of floor, in inflating expanded process, along with inflation ring rigidity strengthens gradually, suffered by floor, pulling force increases gradually, floor depression bar 3 is opened gradually, and floor from outside to inside from coil to coil departs from the constraint of floor depression bar 3, realizes launching in order; In the final stage that floor launches, when floor depression bar 3 and support rail 2 angle are greater than 180 degree, under extension spring 4 pulling force, floor depression bar 3 upwards overturns, and limited plate 2-1 stops, can not impact the reflecting surface of the inflating expanded parabolic antenna of fin-plate type.
