AI Technical Summary
Existing drone-based water sampling devices have uncontrollable and untraceable water sampling depths. Fluctuations in the water surface cause errors in depth calculations, and the ends of the hoses are prone to clogging, which operators cannot handle in a timely manner.
The depth calculation is calibrated by using conductive electrodes to detect the water inlet reference value, and blockages are identified by combining pipeline pressure changes. Sampling is restored through positive pressure backflushing and reel fine-tuning, thus establishing a self-recovery mechanism for depth control and fault handling.
It achieves precise control of water sampling depth and self-recovery from faults, improves sampling efficiency and data traceability, and reduces system errors and human intervention.
