Abstract
A wall-climbing robot system and method for rapid nondestructive inspection of hidden defects in culverts and sluices. The system includes: a robot vehicle body; navigation positioning system and moving system, both mounted on the robot vehicle body; automatic knock inspection system, mounted at the vehicle body front end; mobile ultrasonic rapid inspection system and corrosion inspection system, dual-power system, formed by a non-contact negative pressure adsorption apparatus and rotor booster apparatuses, the non-contact negative pressure adsorption apparatus mounted on the vehicle body bottom, the rotor booster apparatuses mounted on two sides of the vehicle body; and a master controller, communicating with the navigation positioning system, moving system, automatic knock inspection system, mobile ultrasonic rapid inspection system, corrosion inspection system, and dual-power system. The system recognizes positions and categories of internal defects from ultrasonic data and perform concrete permittivity inversion and disease recognition on arbitrary length-continuous survey line ground-penetrating radar data.
