Description

Technical Field

[0001] This utility model relates to the field of lidar technology, and in particular to a ground-based wind-measuring lidar. Background Technology

[0002] Existing wind-measuring laser scanning radars, to prevent the device from being blown over by strong winds, use a cone-shaped rod embedded in the soil, and then a telescopic rod inserted laterally into the soil. This prevents the laser wind-measuring radar from being blown over by strong winds. However, in barren areas, dust or rainwater may blow onto the surface of the inspection component, affecting the wind measurement results and inspection accuracy. For example, a strong-wind resistant laser wind-measuring radar disclosed in Chinese patent (application number: CN202321686500.6) inserts a support rod into the soil, and a telescopic rod is provided on the side surface of the support rod that can be inserted laterally into the soil, improving the stability of the fixation and preventing the laser wind-measuring radar from being blown over by strong winds. However, in barren areas, dust or rainwater may blow onto the surface of the inspection component, affecting the wind measurement results and inspection accuracy. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a ground-based wind-measuring lidar. A sealing strip is installed between the outer shell and the base to create a sealed environment that prevents external rainwater or dust from entering the device and affecting the lifespan of the internal components.
