AI Technical Summary
Existing technologies for detecting hollow walls are inefficient and cannot meet the needs of rapid detection of large-area walls. Furthermore, manual tapping detection has the problem of large errors.
The wall hollow detection device consists of a frame body, transmission rod, drive assembly, and sound wave receiver. The drive assembly drives the transmission rod to move the probe ball to rub against the wall surface to generate vibration. The sound wave receiver collects the sound wave signal for detection, realizing automated excitation and analysis.
It improves the efficiency and accuracy of wall hollow detection, reduces errors caused by human judgment, and is especially suitable for large-area wall detection.
