specific Embodiment approach 1
[0011] Specific implementation mode one: as Figure 1~Figure 4 As shown, the present invention discloses a large-scale expandable reflective surface based on a centrally deformed truss with external winding ribs, including a centrally deformed truss 1, a reflective surface 3, a tensioned back net 4, a support arm 6, a feed source 7, and multiple bifurcated ribs 2 and a plurality of shape-controlling adjustment cables 5, the central deformation truss 1 is a regular polygonal truss composed of an even number of rectangular frame units 1-1 sharing short sides, and the plurality of bifurcated ribs 2 are all symmetrical bifurcations The variable cross-section thin plate, the front edge of each of the bifurcated ribs 2 and the central deformation truss 1 corresponding to the rectangular frame unit 1-1 short side columns are connected by hinges, and the reflective surface 3 is a geometric deflection paraboloid, The central area of the back of the reflective surface 3 is connected t...
specific Embodiment approach 2
[0012] Specific implementation mode two: as figure 2 As shown, this embodiment is a further description of specific embodiment 1. The central deformation truss 1 is composed of a plurality of vertical rectangular frame units 1-1 sharing short side columns to form a regular polygonal prism, and each of the The two long sides of the rectangular frame unit 1-1 are horizontally arranged elongated sheets, and the two short sides of each rectangular frame unit 1-1 are vertically arranged cylinders, and each rectangular frame unit 1 The four corners of -1 are fixed with torsion springs, and each rectangular frame unit 1-1 is fixed with elongated thin strips 1-2 at one diagonal. The central deformation truss 1 can be folded in the center through the first centripetal folding. The two long rods of each rectangular frame unit 1-1 are in the shape of long strips. One diagonal line of each rectangular frame unit 1-1 There are long thin laths 1-2 for stabilizing the rectangular frame uni...
specific Embodiment approach 3
[0013] Specific implementation mode three: as figure 2 As shown, this embodiment is a further description of Embodiment 1. Each of the bifurcated ribs 2 includes a main rib 2-1 and two symmetrically bifurcated secondary ribs 2-2. The two sides of the central position of the main rib 2-1 are respectively connected with the front plate edge of a secondary rib 2-2 through leaf springs to form an acute angle integrated fiber connection. The leaf spring can expand the bifurcated secondary ribs 2-2 to a specified angle.
