AI Technical Summary
Traditional river sediment depth detection devices are prone to sediment being washed away by water flow during the measurement process, making it impossible to accurately read the depth. They also lack range adjustment and accuracy calibration functions, making them unsuitable for detecting different sediment thicknesses in different river channels. Furthermore, they are complex to operate and costly.
The system combines a support component and a measurement component. The support component ensures that the casing is perpendicular to the silt surface through multiple sets of evenly distributed support feet and adjustment components. The sealing plate inside the drill pipe in the measurement component forms a sealed cavity. The sealing plate moves with the drill pipe to reflect the silt depth and retain silt samples. Combined with pressure sensors and distance sensors, the system achieves automated measurement.
It improves the accuracy and sensitivity of measurements, simultaneously enables the collection of silt samples, avoids silt detachment affecting measurement results, simplifies the operation process, and reduces errors and costs.
