Embodiment Construction

[0026] The invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for any limitation on the invention.

[0027] Such as figure 1 As shown, the present invention provides an inflatable film reflecting surface device with shape adjustment function, the whole structure includes a ring-shaped installation base frame 1, and the edge support of the reflection surface located on the inner side of the installation base frame 1 annulus 4. The edge support of the reflective surface 4 is provided with a parabolic canopy 11 and a film reflective surface 12 symmetrically distributed up and down along the annulus in the inner ring, and the parabolic surfaces of the canopy 11 and the film reflective surface 12 form the top and bottom of the inflatable film reflective surface symmetrically. The film surface is in the form of spliced ​​paraboloids. On the outer surface of the canopy 11 and the film refle...

Abstract

The invention discloses an inflatable membrane reflecting surface device with a profile adjustment function. The inflatable membrane reflecting surface device comprises an annular mounting base frame and a reflecting surface edge support, wherein the reflecting surface edge support is arranged on the inner side of the annular surface of the mounting base frame; a canopy with a paraboloid and a membrane reflecting surface which are symmetrically distributed up and down along the annular surface of the reflecting surface edge support are arranged in an inner ring of the reflecting surface edge support; a support framework with a mesh structure is distributed on the outer surface of each of the canopy and the membrane reflecting surface; and a plurality of vertical adjusting devices are arranged on the mesh and cable intersection points of the support framework on the outer surface of the membrane reflecting surface. By the inflatable membrane reflecting surface device, adverse effects of various errors on the profile accuracy in the processing process of the reflecting surface can be compensated; the profile accuracy of the reflecting surface can be effectively improved; the structure is simple; and the manufacturing period is short.

Description

technical field [0001] The invention relates to the technical field of mechanical precision control, in particular to an inflatable thin-film reflective surface device with shape-surface adjustment function. Background technique [0002] The top and bottom of the inflatable reflector are generally composed of symmetrical parabolic films. By inflating the film into a convex lens shape, the signal passes through the transparent film cover (canopy) above and is reflected on the metal-plated reflective surface below. feed source. [0003] Compared with other forms of expandable reflective surfaces, inflatable expandable film reflective surfaces have the advantages of light weight, small folding volume, low cost, and easy unfolding process. Therefore, this reflective surface has become a research hotspot at home and abroad in recent years. [0004] Generally speaking, the surface accuracy of the inflatable reflective surface is poor, mainly due to the following reasons. First, ...
