Problems solved by technology

Although this umbrella-shaped antenna reflector combined with a fixed network has the advantages of high precision, high rigidity and light weight of the metal mesh reflector at the same time, due to the overall reflection type of the umbrella antenna reflector combined with a fixed network The surface is composed of a solid surface part and a mesh surface part. The mesh surface part adopts a metal cable net structure, which inevitably leads to low surface accuracy and poor surface retention ability, especially in antenna reflectors. When the orbital operation has to experience the harsh high and low temperature environment in space, the thermal deformation of the mesh part of the material is more serious, which greatly affects the geometric accuracy of the mesh part, resulting in the stability of the mesh part Poor performance, which affects the performance of the entire umbrella antenna reflector

Embodiment Construction

[0022] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, the fixed-net combined umbrella antenna reflector includes a base, a fixed surface reflector, a deployable component, a reflective cable net and a drive assembly. One side of the base of the umbrella-shaped antenna reflector is fixed on the antenna bracket to fix the umbrella-shaped antenna reflector, the other side of the base is fixedly connected with the solid-surface reflector, and the edge of the base is between the two surfaces of the base. The expandable part includes a plurality of expansion ribs 1, and the number of expansion ribs 1 can be specifically set according to actual conditions. The expansion rib 1 includes a top and a root, and the roots of the expansion rib 1 are respectively hinged to the edge of the base, so that each expansion rib 1 can be expanded around the position ...

Abstract

The invention provides a reflection cable net of an umbrella antenna reflector. The reflection cable net of the umbrella antenna reflector is applied to fixed net combination. The reflection cable net comprises a front tension net, a rear tension net and a tension matrix. The tension matrix is located between the front tension net and the rear tension net and connected with the front tension net and the rear tension net, and the profile of the front tension net and the profile of the rear tension net can be adjusted according to actual requirements due to the arrangement of the tension matrix. Besides, the front tension net and the rear tension net of the reflection cable net are symmetrical, the vertical projection direction is adopted for the tension matrix, and thus the reflection cable net has high profile precision and profile keeping capacity. The invention further provides the umbrella antenna reflector with the reflection cable net.

Description

technical field [0001] The invention relates to a reflection cable net, and also relates to an umbrella antenna reflector with the reflection cable net. Background technique [0002] The umbrella-shaped antenna reflector combined with fixed and network usually adopts the structural form of combining the fixed surface and the mesh surface. The central area of ​​the antenna reflector adopts the traditional fixed surface antenna form, and the other areas adopt the expandable form of the mesh surface with a ring layout. Although this umbrella-shaped antenna reflector combined with a fixed network has the advantages of high precision, high rigidity and light weight of the metal mesh reflector at the same time, due to the overall reflection type of the umbrella antenna reflector combined with a fixed network The surface is composed of a solid surface part and a mesh surface part. The mesh surface part adopts a metal cable net structure, which inevitably leads to low surface accura...
