Underground water level observation device for hydrogeology

Abstract

The invention relates to the technical field of water level observation, in particular to an underground water level observation device for hydrogeology, which comprises an observation box, a storage battery is fixed on the inner bottom surface of the observation box, a threading hole is formed in the bottom surface of the observation box, a measuring rope is inserted in the threading hole, a conductive wire is inserted in the middle of the measuring rope, and the conductive wire is connected with the storage battery. A weight box is fixed to the bottom of the measuring rope, a probe is fixed to the bottom face of the weight box, and the probe is electrically connected with the electric lead; according to the scheme, the top end and the bottom end of the measuring rope are positioned through the top positioning mechanism and the bottom positioning mechanism, inaccurate measurement caused by shaking of the bottom end of the measuring rope at the well bottom can be prevented, the measuring rope can be always kept in the middle of the measuring well, the measuring rope does not make contact with the inner wall of the measuring well, and the measuring accuracy is improved. The situation that the measuring rope is bent due to the fact that the measuring rope is jacked by obstacles such as broken stones or protrusions on the inner wall of the measured well is avoided, and the measuring precision is further improved.

AI Technical Summary

Benefits of technology

This patented technology allows an observing device (such as a hydrophone) to measure seismic waves accurately without getting stuck between other parts like pump boxes due to vibrations caused by sea currents. By placing a weighted tank called a counterbox below the oil level within the observatory's borehole, there is no direct physical interaction between these components while still allowing them work together smoothly. Additionally, this design helps keep any foreign objects out of sight, reducing errors associated with measurements made over long periods of time. Overall, this technical effect improves the reliability and performance of oceanographic exploration operations.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving the accuracy and reliability of observers' measurements when inserting probes inside monitoring wells for detecting groundwater conditions such as ponds, lakes, rivers, etc., particularly during long periods where they may have been exposed without being observed.
