Detection equipment and method for directional depth setting of sound waves in underground vertical hole

The invention relates to the technical field of measurement and mapping, in particular to detection equipment and method for directional depth setting of sound waves in an underground vertical hole, and the equipment comprises a sound wave detector and a sound wave detection probe. The sound wave detector comprises a liquid crystal display screen, a built-in power supply, a power switch, a main control processor, a detector communication circuit, a frequency switching key and a function switching key; a rope locking ring, a buffer soft body, a positioning ring, a buffer rope and a sound wave pickup orientator are sequentially mounted in the sound wave detection probe from top to bottom. The sound wave detector is connected with the sound wave detection probe through a cable, the sound wave detection probe is perpendicular to the ground/underground vertical hole to carry out pickup detection, and data signals are transmitted to the sound wave detector through the cable to carry out imaging visual recognition o
