[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and allocate water to meet the people's needs for water resources for life and production.

[0003] In water conservancy projects, water level monitoring devices are used to monitor the water level inside the river to prevent natural disasters caused by rising water levels. Therefore, water level monitoring and early warning devices are used. Existing early warning devices monitor the water level through a radar water level gauge above the water surface. The radar water level gauge is generally installed at one end of a support rod, and the other end of the support rod is fixed on a fixed rod. This causes a large tensile force on one side of the fixed rod, and the fixing bolts at the bottom of the fixed rod are prone to loosening. In addition, the existing support rod is fixed in length and can only be installed in a fixed position. In order to make the early warning device more stable and applicable to different installation positions, the radar water level gauge is always ensured to be above the river surface. A water level early warning device for construction survey of water conservancy projects is now provided. Utility Model Content
