AI Technical Summary
Existing water level monitoring and early warning devices are difficult to adapt to different installation environments and are not easy to retrieve. Traditional devices cannot effectively monitor water levels at greater depths, especially when the water level in the center of the river is higher than that at the riverbed when the river flow is fast.
It employs fixed and extension components. The fixed components adapt to different ground types through structures such as gears and bolts, while the extension components monitor the water level at deeper depths through a motor-driven threaded rod and extension rod, and achieve water level detection by combining a float and a signal transmitter.
It enables stable installation and deep water level monitoring in different ground environments, improving the adaptability and accuracy of water level monitoring and adapting to changes in river velocity.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water level monitoring technology, and in particular relates to a water level monitoring and early warning device. Background Technology
[0002] Water level monitoring technology is an important component of water resources and hydrological informatization, and it is of great significance for flood control and drought relief, optimal allocation of water resources, and protection of the water ecological environment.
[0003] The problems with the aforementioned technology are as follows: existing water level monitoring and early warning devices are usually fixed with screws, but this fixing method is difficult to adapt to different installation environments, and the retrieval of the water level monitoring part is inconvenient. Traditional water level monitoring devices are not convenient for monitoring water levels at greater depths. When the river water rises and the current is fast, the water level in the middle of the river may be significantly higher than the water level at the riverbed. This is because the water flow is faster in the middle of the river. According to the principle of fluid pressure, the pressure is lower where the flow is faster, while the water flow is slower and the pressure is higher near the riverbanks. This creates a pressure difference towards the center of the river, making the water level in the middle of the river significantly higher than the water level at the riverbed. Utility Model Content
