Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna attitude adjustment technology, and specifically to an adjustment device for antenna adjustment. Background Technology
[0002] Antenna attitude adjustment is a core control element of wireless communication systems, directly impacting signal transmission quality and equipment reliability. Its core value lies in achieving directional transmission of millimeter-wave / microwave signals through precise angle control; even minute deviations can lead to significant signal attenuation. Simultaneously, dynamic tracking capabilities are required to compensate for interference from moving vehicles, strong winds, and other factors, meeting the millisecond-level response requirements of scenarios such as satellite tracking and radar monitoring. In critical fields such as national defense, meteorology, and emergency response, attitude adjustment accuracy directly determines target positioning accuracy and network coverage effectiveness. Furthermore, precise control can prevent abnormal wear of mechanical structures, reduce the risk of equipment damage under extreme conditions, and mitigate energy consumption surges caused by inaccuracies.
[0003] In existing technologies, a dual-gearbox architecture is typically used to adjust antenna attitude. This design achieves dual-degree-of-freedom motion control by independently configuring azimuth and elevation axis gearboxes. However, this antenna attitude adjustment device suffers from the following technical problems: First, the traditional dual-gearbox architecture results in low matching between the azimuth and elevation axis transmissions, leading to significant angular deviations in the dual-axis linkage and a substantial reduction in antenna pointing accuracy. Second, the reduction system is prone to the combined effects of gear backlash and transmission hysteresis under dynamic conditions. When facing high wind speeds or performing rapid maneuvers, this can generate significant torque deviations, causing frequent fluctuations in motor load. Third, the asymmetric wear of transmission components is prominent, with significant differences in wear rates across different hardness regions, drastically shortening the service life of critical components. Fourth, multi-axis coordinated motion exhibits significant phase lag, which may induce plastic deformation of the support structure under extreme conditions, causing severe degradation of antenna performance. These systemic defects not only lead to high equipment maintenance costs but also pose a significant threat to the operational reliability of high-value antennas, with related failures already causing substantial economic losses within the industry.
