Well depth self-adaptive water level detection device based on acoustic and pressure sensor fusion

Abstract

Disclosed is a well depth self-adaptive water level detection device based on acoustic and pressure sensor fusion, which includes an outer shell. A universal detection mechanism is arranged on an inner wall of the outer shell, a connecting wire penetrates through and is fixedly connected to a top inner wall of the outer shell, the universal detection mechanism is configured to perform multi-dimensional adjustment to keep the device vertical during detection, to prevent a detection error due to inclination, and the universal detection mechanism includes a diameter changing assembly. The universal detection mechanism composed of sliding plates, a rotating frame, and a ball head achieves triple movements: 360-degree circumferential rotation, left-right swing, and front-back rotation, and is combined with gravity correction of balancing weights, to ensure that an acoustic probe always maintains in a vertical state, and automatically corrects an attitude to prevent deviation of a detection path
