[0001] The utility model belongs to the technical field of water conservancy detection, and in particular relates to a reservoir water level monitoring and early warning device. Background Art

[0002] The water conservancy department needs to focus on monitoring the water level of the reservoir to prevent it from being too high. When the water level of the reservoir exceeds the warning line, it is easy to induce serious floods, affecting the health and property safety of residents. The existing float-type water level monitoring device is easily affected by the impact of water flow and the organisms or garbage flowing in the water, resulting in failure to work normally and unable to monitor the water level changes of the reservoir. The Chinese patent (CN212621017U) discloses a water level monitoring device for small and medium-sized reservoirs. Although the device is equipped with a protective cover, the measuring reference pole is still exposed to the outside and is still affected by the impact of water flow and obstacles in the water; although the device uses a camera to shoot the measuring reference pole and the water gauge, it is not easy to observe the water level information on the water gauge at night. It is urgent for those skilled in the art to propose a reservoir water level monitoring and early warning device that can avoid the impact of water flow and obstacles in the water.
