A pluggable downtilt angle manual adjustment device and antenna

Abstract

The invention provides a pluggable downtilt manual adjustment device and an antenna, the pluggable downtilt manual adjustment device includes an angle adjustment module and a transmission module, and the angle adjustment module is a manual adjustment module or an electric angle adjustment module , the manual adjustment module includes a transmission rod, a fixed panel, a manual angle adjustment wheel and a limit snap ring, and the transmission rod is provided with a flat lower wear area, a transmission rod sleeve surface, a transmission rod snap ring groove, and an end The tail is provided with a pair of plugs; the transmission module includes a transmission screw, a fixed frame, a transmission nut and a limit snap ring. The device provided by the invention can realize the plug-in and pull-out function, avoids the need to remove the entire antenna from the high pole and tower for repair, facilitates maintenance and replacement, reduces the risk of tower climbing operations, and can realize switching with the electric angle adjustment device at the same time.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a pluggable downtilt manual adjustment device and an antenna. Background technique [0002] In the mobile communication system, in order to optimize the wireless signal covered by the area, and to suppress the mutual interference of the same frequency signals, it is necessary to adjust the downtilt angle of the base station communication antenna reasonably. In the prior art, the main way to adjust the downtilt angle of the base station antenna is to adjust the downtilt angle by changing the dielectric coupling length and angle position of the phase shifter. In order to realize the remote control function, the transmission system is generally used to remotely control the antenna phase shifter. The transmission system includes a transmission module and an RCU module. The transmission principle is usually to drive the transmission screw and the plastic nut ...

AI Technical Summary

Problems solved by technology

This means that a multi-frequency antenna needs multiple sets of downtilt manual adjustment devices, thus occupying more antenna space, not meeting the trend of miniaturization, and increasing the cost of materials and assembly

[0004] As we all know, base station antennas are generally hung on outdoor high poles and towers. The operating environment is harsh and exposed to the sun and rain all the year round. Especially for some extremely cold and extremely cold regions, as the service life of the antenna increases, the manual adjustment module is prone to poor adjustment, For faults such as jamming, the entire antenna needs to be removed from the high pole and tower for repair, which not only affects the normal use of the antenna, but also makes it difficult to climb towers and high-altitude operations, and the maintenance cost is high
