[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and groundwater resources and the environment. They are used to control and allocate natural surface water and groundwater. Water is a precious resource indispensable to human production and life. Only by building water conservancy projects can we control water flow, prevent flood disasters, and regulate and distribute water to meet human demand for water resources. Various data need to be detected during the implementation of water conservancy projects, and water level meters are the most common measuring instruments.

[0003] A water level measuring instrument for a water conservancy project disclosed in Chinese patent CN202321674544.7 can adjust the height of the water level measuring instrument by using a height adjustment structure, so that users can complete the measurement task without squatting for a long time, thereby solving the problem that the water level measuring instruments in the prior art are directly placed on the ground and their height cannot be adjusted according to needs, resulting in the user frequently squatting to operate, which is inconvenient. However, the water level measuring instrument for the water conservancy project still requires manual operation and measurement before reading the data, and cannot realize real-time monitoring of the water level data.
