AI Technical Summary

Technical Problem

During the use of the dam, settlement caused the fixing plate to be unable to fit tightly against the dam surface, affecting the normal operation of the monitoring device.

Method used

A pressure sensor is used to detect the gap between the fixed plate and the ground. The controller starts the servo motor to drive the screw to rotate, which moves the fixed plate downward to keep it in contact with the dam surface. A limit structure is used to prevent the fixed plate from rotating, ensuring that the monitoring box can monitor normally.

Benefits of technology

This ensures that the fixing plate remains in close contact with the dam surface even during dam settlement, guaranteeing the real-time monitoring function of the monitoring device and preventing monitoring interruption.
