Description

Technical Field

[0001] This utility model relates to the field of radar component technology, specifically a portable wind-measuring lidar angle adjuster. Background Technology

[0002] Portable wind-measuring lidar plays a crucial role in numerous fields such as meteorological monitoring, wind resource assessment, and drone flight support. The angle adjuster, as a key component, significantly impacts the lidar's ability to accurately acquire wind speed data from different directions. The angle adjuster of a portable wind-measuring lidar primarily relies on mechanical rotation and a reduction drive principle. Through the precise rotation of the reduction drive, the lidar's transmitting and receiving devices can change angles in multiple directions.

[0003] The existing portable wind lidar angle adjusters still have the following problems when in use: In terms of the deceleration drive, since they often need to perform multi-directional angle adjustment of the wind lidar, each angle adjustment mechanism is usually equipped with a deceleration drive. During high-frequency and long-term angle adjustment, the deceleration drive is prone to overheating. Excessive temperature will affect the performance and life of the deceleration drive, and may even lead to deceleration drive failure. At this time, since the deceleration drive is often irregularly distributed at the top and bottom of the adjuster, its maintenance and repair are relatively inconvenient. Utility Model Content
