Technical Field

[0001] The utility model relates to the technical field of water level monitoring, in particular to a water level alarm device for a hydropower station. Background Art

[0002] A hydropower station is a power station that uses the kinetic energy of a strong water flow generated by a water level difference to generate electricity. It is also called a hydroelectric power station. It uses the water energy of a river to drive a turbine to drive a generator set to generate electricity. During the operation of a hydropower station, accurate monitoring of the water level is an important task to ensure the safe operation of the hydropower station. However, in the process of monitoring the water level, it is generally done through regular manual inspections and expensive professional equipment, which is not only time-consuming and labor-intensive, but also costly. In addition, due to the limitations of manual inspections, water level anomalies may not be discovered in time, posing potential risks to the safe operation of the hydropower station. Therefore, we propose a water level alarm device for a hydropower station to solve the above problems. Utility Model Content
