Water level monitoring device for water conservancy project

The utility model relates to the technical field of hydraulic engineering, in particular to a water level monitoring device for hydraulic engineering, which comprises a box body, one side of the box body is fixedly connected with two fixing frames, the top of the box body is respectively and movably connected with two exhaust holes and a guide pipe, the inner wall of the guide pipe is movably connected with a floating ball, and the floating ball is movably connected with the water level monitoring device. According to the improved detection device, a mesh hole is formed in the top of an exhaust hole, pollutants in air are prevented from blocking a pipeline in the water level monitoring device, the service life of the device is prolonged, small holes are formed in the outer walls of a water inlet pipe and an extension pipe, and when the liquid level of water changes, the water level of the water level is changed, and the water level of the water level is changed. A water body can balance and adjust the pressur
