The existing monitoring devices for water conservancy projects are not convenient for adjusting the position of the detection device, and they can only be installed in fixed positions. At the same time, when detecting the maximum water level, they are easily affected by waterweeds, thus reducing the sensitivity of the detection device. Therefore, there is an urgent need for a flood season water level detection device for water conservancy and hydropower projects to overcome the above defects. Content of the Utility Model
[0004] The purpose of the utility model is to provide a flood season water level detection device for water conservancy and hydropower projects, which has the advantages of convenient adjustment and high sensitivity, so as to solve the problems put forward in the above background technique.

[0014] The utility model adjusts the positions of the first detection and alarm component, the second detection and alarm component, and the connecting rod by setting a longitudinal adjustment component. The highest value of the flood season water level is detected by setting the first detection and alarm component and the second detection and alarm component. The connecting rod is set to facilitate the connection between the longitudinal adjustment component and the second detection and alarm component. When adjusting its height, the first waterproof motor is turned on. The first waterproof motor drives the threaded rod to rotate, and under the action of the slider, the positions of the connecting rod, the first detection and alarm component, and the second detection and alarm component are changed. During detection, under the buoyancy of water, the floating block drives the fixed frame and the connecting rod to move upward.
