Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level detection device. Background Art

[0002] Water level detection refers to the process of measuring the height or depth of water. It is usually used to monitor the water level changes of rivers, lakes, reservoirs and other water bodies, as well as the statistics and analysis of relevant data such as hydrology and meteorology. It can also be used in construction, environmental monitoring and other fields. In water conservancy projects, water level detection is a very important task. It can provide information such as the trend, cycle, and amplitude of water level changes, which is of great significance for flood prediction, flood control and drainage, and water conservancy project design. At the same time, water level detection can also provide a basis for water resource management, water pollution control, and ecological protection. The use of existing water level detection devices generally uses a detection rod to be directly inserted into the water, and then records by reading the scale bar engraved on the measuring rod. When this method is inserted into the water, it is not possible to intuitively observe whether the rod body is perpendicular to the horizontal plane. If it is not vertical, it will affect the measurement results and bring inconvenience to the user. Utility Model Content
