Antenna azimuth transition adjusting device

Abstract

The invention provides an antenna azimuth transition adjusting device comprising a support frame (101), a power input motor (102), a power transition motor (103), a grooved pulley (201), a puller (202), a driving gear (203), a switching gear (204) and a driven gear (205); the power input motor (102) is directly or switched to be coaxially fixed with the grooved pulley (201); the power transition motor (103) is directly or switched to be coaxially fixed with the puller (202); the driving gear (203), the switching gear (204) and the driven gear (205) can form a gear set; a plurality of sets of worm and gear devices are arranged, and corresponding spur gears (106) and spur racks (107) are arranged so as to convert rotations into linear displacements. The grooved pulley and the worm and gearsare combined, thus changing a conventional mode of sun gear and planetary gear multistage gear drive, reducing parts number, saving assembling time, and reducing fault points.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna azimuth conversion and adjustment device. Background technique [0002] In a wireless communication system, the base station antenna is the interface between the transceiver and the external propagation medium. In the case that the physical position of the antenna of the base station remains unchanged, the phase shifters of each unit are connected in the antenna and the output phase of each phase shifter is controlled by an electronically controlled power output device through a transmission device. [0003] In the case of site sharing, in order to avoid installing too many antennas with different frequency bands at the same site and to reduce the load-bearing burden of the communication tower, a multi-frequency antenna integrating multiple frequency bands with one antenna is usually used. The azimuth of each frequency band in the multi-frequency antenna needs to use...

AI Technical Summary

Problems solved by technology

The azimuth of each frequency band in the multi-frequency antenna needs to use its own phase shifter. Usually, the phase shifter of each frequency band in the antenna corresponds to a separate controller, which leads to too many internal controllers in the antenna. Increased size of device and antenna

[0004] Since the communication interface and control interface increase proportionally with the increase in the number of frequency bands, the space at the bottom interface is tight, and manufacturing, engineering, installation and maintenance are difficult

With the integration and scarcity of antenna resources, electric-tunable base station antennas are developing in the direction of multi-frequency and miniaturization. The current lower end of the antenna has insufficient space in the layout under the condition of multi-frequency compatibility. At the same time, one frequency band corresponds to one electric The existing technical solution of the control device, due to the increase in the number of frequency bands, the cost and control difficulty increase accordingly
