Description

Technical Field

[0001] The utility model relates to the technical field of underground water level measurement, and more specifically, to an underground water level measuring device. Background Art

[0002] The measurement of groundwater levels can help assess the sustainable use and management of water resources. Understanding the height and changing trends of groundwater levels, as well as the recharge and consumption of groundwater, can help rationally plan and allocate water resources and avoid over-exploitation or unbalanced use of water resources.

[0003] At present, there are two principles for observing groundwater level measurement, namely: the principle of buoyancy induction and the principle of liquid conductivity. The well water level measuring rope is a measuring tool that uses the principle of liquid conductivity to measure the depth of groundwater level.

[0004] However, in the prior art, when measuring the groundwater level at a location such as a wellhead, the water level can only be measured by conducting liquid away from the wellhead, which is not convenient for synchronous measurement of the water depth. Therefore, when the groundwater depth needs to be detected, additional measurement is required, which is less convenient to use.

[0005] In addition, when measuring, the supporting devices of the existing groundwater level measuring devices are mostly fixed and cannot be flexibly adjusted for wellheads of different diameters. Therefore, when encountering a wider wellhead, it is easy for the supporting device to fail to be installed at the wellhead position, affecting the convenience of use. Utility Model Content
