Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water level monitoring equipment, and in particular relates to a water level monitoring device for a hydropower station. Background Art
[0002] Hydropower generation projects refer to engineering construction projects that convert water energy into electrical energy. The water energy used in hydropower generation is mainly the potential energy contained in the water body, that is, the huge potential energy generated by the water level difference is used to drive the water flow to quickly impact the hydraulic turbine, so that the turbine can convert the potential energy of the water into electrical energy. However, it is difficult for the water level of natural water sources in nature to reach a large water level difference. In order to achieve the conversion of water energy into electrical energy, different types of hydropower stations need to be built, and the water flow of natural water sources can be cut off by hydropower stations to artificially create water level differences. Water level monitoring devices are equipment used by hydropower station managers to monitor water levels.
[0003] Water level monitoring is an indispensable part of water conservancy project monitoring. Water level monitoring mainly monitors the water intercepted by water conservancy projects such as dams. At present, water level monitoring mostly adopts methods such as setting up benchmarks or marking water level warning lines on the inclined wall of the dam. The above methods have at least the following problems: in rainy weather and other environments with poor light, people often cannot directly see the benchmarks or the warning lines on the inclined wall of the dam, resulting in people not being able to make a more intuitive judgment of the water level.
[0004] Therefore, we propose a new water level monitoring device for hydropower stations to solve the above problems. Utility Model Content
