Embodiment Construction

[0041] The sealing structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like figure 1 As shown, a spatial block metal truss antenna cover is spliced ​​from a plurality of unregulated triangular antenna hood unit block 1.

[0043] like Figure 2-11 As shown, the antenna cover unit block 1 includes a metal skeleton 2, a skin 3, a rod press 4, and a nodes 5.

[0044] The metal skeleton 2 is welded by three rods 11 and 3 node column 12, and the overall is a spatial triangle, and the node column 12 constitutes a vertex of a triangle.

[0045] The outer side of the top of the metal skeleton 2, that is, the outer side of the top portion of the rod 11 is provided with a sheet of wire rope 6 for providing a wire rope 6 as a macrote 3 tension, and the node pressure strip 4 and a rod press 5. The metal skeleton 2 is disposed, its shape is a shaped structure, and is adapted to the shape of the metal sk...

Abstract

The invention belongs to the technical field of radar radomes, and discloses a space block metal truss radome and a sealing method thereof. The space block metal truss radome comprises a plurality of triangular radome unit blocks with irregular sizes, wherein each radome unit block comprises a metal framework, a skin, a rod piece pressing strip and a node pressing strip, the skin is made of a PTFE membrane material, the skin is tightly attached to the outer surface of the metal framework after being tightened, the skin is fixed to the metal framework through the node pressing strip and the rod piece pressing strip, a viscoelastic body glue is attached to the positions, close to the outer surface of the skin, of the inner sides of the rod piece pressing strip and the node pressing strip, the viscoelastic body glue is tightly filled in gaps between the rod piece pressing strip and the upper surface of the skin and between the node pressing strip and the upper surface of the skin in a pressure-bearing mode, and a closed glue filling area with the same shape as the radome unit block is formed. According to the invention, the sealing problem of the radome unit blocks and the splicing positions of the radome unit blocks is solved, the structural form is well matched with the structural characteristics of the sealant and the skin, the weather resistance is good, the long-term sealing reliability is high, and maintenance is easy.

Description

Technical field [0001] The present invention relates generally to the field of radar space covers, and in particular, to a spatial block metal truss antenna cover and a sealing method thereof. Background technique [0002] The antenna cover is mainly used for radar from being affected by external harsh environments such as winds and snow, and the electromagnetic wave is "transparent", and the antenna cover is a modern high-performance antenna system protection equipment to ensure that the antenna system is normal and reliable. Effective measures. [0003] The spatial block metal truss antenna cover is a major form of ground radar space cover for fixed site large ground radar. Usually, this type of antenna cover is assembled by several space triangular antenna unit blocks. Each antenna cover unit block consists of a space triangular metal skeleton and a skin, and the skin is generally a thin film material, secured to a triangular unit block by screws and compact strips. Metal skel...
