Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to a water level monitoring device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to mitigate water-related disasters and develop and utilize water resources. They are categorized by their service objectives, including flood control projects, farmland irrigation projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. These projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.
