Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water level measuring device for water conservancy project management. Background Art

[0002] Water level refers to the elevation of the free water surface relative to a certain base surface. The distance between the water surface and the river bottom is called the water depth. The base surface used to calculate the water level can be a certain characteristic sea level elevation as the zero point leveling base surface, called the absolute base surface, and the Yellow Sea base surface is commonly used; or the elevation of a specific point can be used as a reference to calculate the zero point of the water level, which is called the station base surface. The water level is the most intuitive factor reflecting the water condition of the water body. Its changes are mainly caused by the increase or decrease of the water volume in the water body. The water level process line is a curve showing the change of water level at a certain place over time. The horizontal coordinate is time and the vertical coordinate is water level.

[0003] In the existing water level measurement, most of the water level is determined by the length of the sagging line. However, when the existing water level measuring device is used, the liquid level sensor of the water level measuring device needs to be moved to the water surface. This method will cause the measurement center of gravity to shift, and if there is no additional fixing device, it will cause the measurement process to tip over, resulting in measurement errors and accidents. Therefore, a water level measuring device for water conservancy project management is proposed. Utility Model Content
