The application can indicate the water depth situation in real time 24 hours a day through lights in advance, and intuitively remind the staff of the water situation through lights of different colors.

[0004] There are still some shortcomings in the above-mentioned related technologies. For example, during the installation of the early warning device, it is necessary to manually dive underwater and fix the base on the riverbed. The installation process is manpower-consuming, and the device will be shaken by the impact of the river water, affecting the device's monitoring of the water level. Therefore, in order to solve such problems, we propose a water level monitoring and early warning device for water conservancy projects. Utility Model Content

A rope is wound around the shaft of the winding roller, and a positioning anchor is attached to the end of the rope on the winding roller. A driving mechanism for driving the winding roller to wind the rope is provided on one side of the support frame.

[0011] By adopting the above technical solution, the driving mechanism cancels the limit on the output shaft, the positioning anchor sinks, and the floating block is positioned. When the early warning device needs to be retracted, the driving mechanism drives the winding roller to wind the rope and retract the positioning anchor.

[0016] Furthermore, the light warning assembly includes a lamp holder, which is fixedly mounted on the top of the protective cover, connected to the output end of the water level monitoring terminal, and a warning light is arranged on the top of the lamp holder.

[0017] By adopting the above technical solution, the warning light will light up when the water level is higher or lower than the preset value.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] By installing the float and the positioning mechanism, the float is placed on the water surface, and the water level monitoring terminal controls the positioning mechanism to complete the positioning of the float, thereby improving the installation efficiency. During use, multiple solar cell modules store and supply electricity, and the radar level gauge monitors the water level in real time, and uploads the data to the water level monitoring terminal, which is then transmitted to the user end. When the water level is higher or lower than the preset value, the light warning component issues a light warning, thereby reducing the impact of river flow on the monitoring data.
