Description

TECHNICAL FIELD

[0002] As an important water body on the earth, underground water is one of important water sources for agricultural irrigation, industry and mining and cities due to stable water quantity and good water quality, and is closely related to human society. However, due to excessive exploitation and unreasonable utilization of underground water by human beings, the underground water level is often seriously lowered to form a large area of underground water lowering funnel, and in urban areas where the underground water is intensively used, ground subsidence is also caused. In addition, a large amount of industrial wastewater and domestic sewage often seriously pollutes the underground water source and endangers the underground water resource. Therefore, it is of great significance to systematically study the formation and types of underground water, the movement of underground water and the mutual conversion and supply relationship between underground water, surface water and atmospheric water.

The device utilizes the water body conduction principle, and the drilling wall is usually humid when it approaches the underground water level, which causes current to flow before the conductor reaches the water surface, resulting in large measurement data errors. The device is suitable for promotion, but it does not have a moving mechanism. When the water level at different positions needs to be measured, the operator needs to manually carry and move the device. However, the device has a large weight and a large volume, which increases the difficulty of carrying for the operator and requires a lot of effort.
