Abstract

The invention discloses a variable focal length reflection surface device with a ring column cable net structure, which is used to solve the problem that the focal length of the existing reflection surface device is not variable. It includes a central pillar (1), a sleeve set device (2), a fastening cable (3), an adjusting cable (4), a reflection cable (5), an expandable fixed truss unit (6) and a reflection mesh surface (7). The sleeve set device (2) includes two moving sleeves sleeved on the center pillar (1), and the two moving sleeves move along the center pillar (1), driving the fastening cable (3) and the reflection cable (5) ) to generate a distance difference, and control to realize self-folding; at the same time, the reflective mesh surface (7) is folded to realize the mutual conversion between the parabolic surface and the plane of the reflective mesh surface (7), and the zoom operation of the reflective surface device is completed. The present invention can realize the mutual transformation of the shape of the reflective mesh surface (7) between the paraboloid and the plane, reflect or converge electromagnetic waves or light energy at different distances, and can be used in space or on the ground as a reflector or concentrator.

Description

technical field [0001] The invention belongs to the technical field of communication and electronics, and relates to a variable-focus reflection surface device with a ring-column cable-net structure, which can realize the convergence or reflection of electromagnetic energy or light energy between different distances, and is suitable for deployable antennas mounted on satellites or on the ground structure. Background technique [0002] Zoom technology is widely used in various fields. For example, in the camera lens in the optical system, the focal length can be appropriately changed by rotating the focus ring of the lens to realize the change of the focusing distance, so as to complete clear shooting of objects at different distances. [0003] However, in the reflector system commonly used in the field of communication and electronic technology, there are many difficulties in the application of zoom technology. The specific reasons can be summarized as follows: for small-siz...
