For example, the benchmark lacks a cleaning mechanism, so that its surface will be immersed in water for a long time, resulting in impurities such as algae attached to its surface, making it difficult to observe the benchmark scale. In order to avoid such problems, a water level monitoring device for water conservancy projects is proposed to solve the existing problems. Utility Model Content

[0006] Preferably, the driving mechanism includes a servo motor, which is fixedly arranged on the top of the mounting frame. The output shaft of the servo motor is fixedly connected to the rotating shaft through a coupling. The surfaces of the rotating shaft and the threaded rod are fixedly connected to pulleys, and a belt is connected for transmission between the two pulleys.
