[0002] With the intensification of global climate change, extreme weather events occur frequently, and flood disasters are becoming increasingly serious. Water conservancy projects such as reservoir dams and dikes are important facilities to protect people's lives and property safety. However, these facilities may be affected by various factors during long-term use, such as geological changes and water flow erosion, leading to safety hazards. Water level detection in water conservancy projects can monitor water level changes in real time and timely detect abnormal conditions, providing important protection for the safe operation of water conservancy projects. This helps to prevent dam breaches and other safety incidents, ensuring the safety and stability of water conservancy projects.

Modern water level detection technology combines image processing and machine learning algorithms to achieve efficient and intelligent water level monitoring. The application of these technologies not only improves the accuracy and real-time performance of water level detection, but also reduces monitoring costs, promoting the widespread application of water level detection in water conservancy projects. However, in remote areas and complex geological mountainous areas, modern water level detection technology is difficult to popularize due to environmental conditions, leading to inconvenient water level detection in these areas. Therefore, the present application proposes a mechanical water level detection device for water conservancy projects. UTILITY MODEL CONTENTS
