Abstract

The invention relates to the technical field of hydrogeological detection, and discloses an ultrasonic guided wave underground water level detection device which comprises an ultrasonic probe shell, a radio frequency assembly is arranged in the ultrasonic probe shell, and a probe rod assembly is arranged at the bottom of the ultrasonic probe shell. The probe rod assembly comprises a longitudinal wave coupling solid rod, a hollow connecting rod, a guided wave propagation hollow rod and a blade foot, the radio frequency assembly comprises an inner layer sleeve, a plurality of wire bundles are arranged in the inner layer sleeve, and the bottom of each wire bundle is fixedly connected with a phased array infinitesimal element. Ultrasonic longitudinal waves are transmitted through a phased array infinitesimal in an ultrasonic probe shell, so that the longitudinal waves repeatedly interfere in a longitudinal wave coupling solid rod to form cylindrical guided waves propagating along the inner wall of a guided wave propagation hollow rod, the cylindrical guided waves propagate to the deep part of a stratum and are reflected by underground water, and the infinitesimal receives and analyzes the propagation time of the reflected waves to calculate the water level depth. The problem that traditional drilling measurement and an electromagnetic method are low in detection efficiency is solved, and the water level detection accuracy and efficiency are improved.
