Feeder waveguide penetration opening sealing assembly

Abstract

The invention relates to the technical field of the sealing of radar equipment, and in particular relates to a feeder waveguide penetration opening sealing assembly. The assembly comprises a sealing framework, wherein square-hole-shaped embedding frames are distributed in the sealing framework in parallel or in an array manner, and the embedding frames penetrate through the surface of the sealing framework along the hole depth direction. The assembly also comprises a filling body filling the embedding frames, wherein the appearance of the filling body is in a cuboid shape, and the appearance shape of the cross section of the filling body is matched with the appearance shape of the cross section of the embedding frame; and the filling body at least comprises a rubber sealing block and a supporting and straining block superimposed on the rubber sealing block, and a through hole which is used for a specific cable or a feeder or a waveguide to penetrate through is formed in the rubber sealing block in a penetrating manner. By adopting the assembly, the modularized orderly embedding of the feeder, the waveguide and the cable can be realized; and meanwhile, the manufacturability and the sealing reliability of the module can also be effectively guaranteed, and the maintenance and replacement efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of radar equipment sealing, in particular to a feeder waveguide penetration opening sealing assembly. Background technique [0002] If the penetrations of the feeder, waveguide, power supply, control cables, etc. between the position radar or shipborne radar antenna and the equipment control room are not well sealed, dust accumulation will occur on the cable or waveguide at the penetration opening. Abrasion, aging or even water ingress. Especially for expensive flexible waveguides, the cost of damaged replacement is even higher. At present, for the sealing protection of the above-mentioned gaps, styrofoam or even direct cement potting is often used. The shortcomings are self-evident: any structure will have the need for daily maintenance, and it is even hoped that it can be quickly repaired when the structure is damaged. Replace function. However, whether it is sealed with foam glue or cement, it is a one...

AI Technical Summary

Problems solved by technology

However, whether it is sealed with foam glue or cement, it is a one-time permanent seal. Although the expectation is to ensure its sealing performance, it often not only fails to achieve a good sealing effect, but also leads to structural damage. Convenient maintenance and replacement operations

In addition, there are often a large number of feeders, waveguides, power lines, control cables, etc. at the same penetration, and the lines are densely intertwined with each other, with high confusion and time-consuming identification one by one, which greatly reduces the efficiency of actual maintenance operations. sex
