Description

Groundwater level monitoring device Technical Field The utility model relates to the technical direction of underground water level monitoring, in particular to an underground water level monitoring device, belonging to the field of hydraulic rings. Background In the fields of hydrogeology reconnaissance, water resource management, geological disaster early warning and the like, accurate monitoring of the underground water level is an important link for acquiring key data, at present, a common underground water level monitoring device is used for measuring in a mode that a floating plate is matched with a flexible tape, but the traditional device has obvious defects in practical application that the inner wall of a monitoring well is often not completely vertical, the conditions of bulges, impurities and the like possibly exist, and when the floating plate floats up and down along with the change of the water level, the floating plate is easily subjected to position deviation caused by the influence of the environment of a well wall, so that the flexible tape between the floating plate and a top plate is inclined.
