Description

Technical Field

[0001] This invention relates to the field of flow measurement equipment technology, and in particular to an automatic lifting device for ADCP. Background Technology

[0002] The Acoustic Doppler Current Profiler (ADCP) is a new type of ocean current measurement instrument, commonly used for observation in special areas such as cross-sea bridges, offshore wind farms, and hydrological stations. In these areas, the presence of pile foundations causes localized changes in water flow patterns, with the velocity variation range on the back side being greater than that on the front side. The intensity of sediment erosion varies depending on the location of the pile foundations, resulting in a relatively small erosion area, primarily concentrated near the pile foundations. Therefore, a buoy-type ADCP is needed for monitoring. However, existing buoy-type ADCPs sway up and down and left and right as the buoy is affected by waves during observation, impacting measurement accuracy. Summary of the Invention
