Portable automatic measuring instrument and measuring method for ground water level and well depth

Abstract

The invention relates to a portable automatic measuring instrument and a measuring method for ground water level and well depth, and belongs to the technical field of special equipment for monitoringground water level and well depth. One end of a measuring line (24) is wound on a main line wheel (49); and the other end of the measuring line (24) passes between a length counter sensor (22) and a line conveying wheel (50), and is connected with a measuring probe (25) through a first measuring line guide hole (23) and then a second measuring line guide hole (51) at the bottom of the shell. The measuring line (24) is composed of a measuring line insulating layer (26), a first lead wire (27), and a second lead wire (28); and the measuring line insulating layer (26) is arranged outside the first lead wire (27) and the second lead wire (28). According to the portable automatic measuring instrument and the measuring method for ground water level and well depth, the measurement for the water level and the well depth are integrated, so that the measurement is greatly simplified, the labor intensity is relieved, the errors that may be caused by artificial sensations in the well depth measurement are eliminated, and the accuracy of the measurement data is greatly improved.

Description

technical field [0001] The invention relates to a portable automatic groundwater level well depth measuring instrument and a measuring method, which can conveniently obtain accurate and reliable groundwater level and well depth measurement data, provide basic data support for the rational development, utilization and protection of groundwater resources, and belong to groundwater level and well depth monitoring special equipment technology field. Background technique [0002] Water resources are one of the elements of the natural environment that human beings rely on for survival and development, and are an important part of the ecosystem. Among them, groundwater resources play a more important role. In the vast areas of northern my country, groundwater accounts for the total water supply for domestic use More than 80% of the amount. Due to the long-term overload mining, most areas in northern my country are in a state of groundwater overexploitation, and some parts are in a ...
