Abstract

The invention discloses a rotary joint used for antenna erection, which relates to the technical field of antenna joints. In order to solve the problem in the prior art that the number of microwave signal channels that can be used by the antenna feed system of the radar is relatively small, resulting in the antenna and receive and transmit power are limited. The diverter ring is arranged on the top of the seven-way rotary joint mechanism, and the diversion ring and the seven-way rotary joint mechanism are connected by bolts. The seven-way rotary joint mechanism includes a single-way joint sleeve, and there are seven single-way joint sleeves. The outer side of the single-way joint sleeve is provided with a bracket edge, and the bracket edge and the single-way joint sleeve are provided with an integrated structure, the outer surface of the bracket page is provided with locking bolts, and the single-way joint sleeves pass through Locking bolt connection, the inside of the single-way joint sleeve is provided with a single-way control joint, and the single-way control joint includes an inner shaft joint, an outer shaft joint and a metal flange, and the metal flange is set on the inner shaft joint one end.

Description

technical field [0001] The invention relates to the technical field of antenna joints, in particular to a rotary joint used for antenna erection. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna, and the basic characteristic parameter...
