[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydroelectric power generation projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and sea reclamation projects. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. The existing reservoir water level measurement generally uses the fishing measurement method.

[0003] The existing measuring device requires the staff to take a boat to the water area to be measured, put the iron lump into the water, and hold the lifting rope with the other hand until the iron lump touches the river bottom. The staff reels in the rope to retract the iron support, and then measures the position of the lifting rope parallel to the water level to obtain the water depth. However, this working method cannot guarantee the safety of the staff and has high labor intensity. For this reason, we propose a water level measuring device for water conservancy projects to solve the above problems. Utility Model Content
