Description

Technical Field

[0001] The present invention relates to the technical field of water level monitoring devices for hydropower station dams, and particularly to an anti-scouring and energy-dissipating water gauge device for the upstream side of a hydropower station dam. Background Art

[0002] In the context of the global active response to climate change, hydropower can achieve a clean replacement of fossil energy, accelerate the green and low-carbon transformation of energy, and is an important way to boost carbon peak and carbon neutrality. The water gauge on the upstream side of a hydropower station dam is used to measure the water level of the upstream reservoir of the dam. The water level observation data will be directly applied to the dam safety monitoring and the water regime forecast of the hydropower station. The reliability of the observation data will directly affect the accuracy of the dam safety monitoring results and the water regime forecast results, and is closely related to the safety of the hydropower station dam and the lives and property of the people in the downstream area. Therefore, the water level observation equipment, i.e., the water gauge, on the upstream side of the dam must be firm and reliable to ensure the stable and reliable quality of the water level observation data.

[0003] At present, most of the water gauges on the upstream side of hydropower station dams are made by drawing scales and corresponding elevations on flat metal plates, customized tiles or the smooth surfaces of hydraulic structures. However, most of the water gauges on the upstream side of hydropower station dams are located near the intake of the hydropower station plant units, flood discharge channels and spillways, where the water level fluctuates frequently and the hydraulic conditions are complex and changeable. Affected by this, the water gauges on the upstream side of hydropower station dams often suffer from damage such as being washed away by the water flow and partial detachment during the flood season. This has a direct impact on the water level observation in front of the dam, a greater impact on the analysis of the dam safety monitoring results and the accuracy of the water regime forecast results, affects the power generation plan and power generation efficiency of the power plant, and more seriously endangers the lives and property of the people in the downstream area.
