Description

Technical Field

[0001] The present invention relates to the technical field of water level monitoring equipment, in particular to a water level early warning device for a water conservancy project. Background Art

[0002] With the intensification of climate change and the frequent occurrence of extreme weather, the risk of water level fluctuations faced by water conservancy projects has increased significantly. Traditional manual inspection methods are difficult to meet the needs of modern flood prevention and disaster reduction due to problems such as poor timeliness and insufficient accuracy. If water level abnormalities are not warned in time, they may cause major disasters such as urban waterlogging and dam collapse, resulting in loss of life and property. Against this background, water level warning devices for water conservancy projects have come into being. By integrating high-precision sensors and wireless communication technology, real-time automatic collection and dynamic analysis of water level data can be achieved. Some devices are combined with new protective structures such as solid shore cages, taking advantage of their corrosion resistance and high ductility to operate stably in complex hydrological environments, providing all-weather monitoring and intelligent warning for key areas such as reservoirs and rivers, effectively improving disaster response capabilities, and promoting the transformation of water conservancy management to automation and intelligence.

[0003] In the actual use of existing devices, after long-term use of non-contact radar water level meters, a large amount of dust will adhere to the inner wall of the radar water level meter shell, thereby affecting the radar's measurement of the water level.
