Water level observation device for water conservancy project

The utility model discloses a water level observation device for hydraulic engineering, which comprises a base, two guide rods are installed on the surface of the top end of the base in parallel, a floating disc is movably installed on the outer surfaces of the two guide rods together, a buoyancy mechanism is arranged in a sleeve, a part convenient to identify is installed on the surface of the sleeve, and the floating disc is movably installed on the surface of the sleeve. An observation component is installed between the sleeve and the warning ring. A series of structures are arranged, the warning ring corresponds to the graduated scale on the identification plate, the structural stability is improved, the graduated scale is convenient to identify, the surface of the graduated scale can be brushed with reflective paint to achieve a prompting effect, the floating pointer floats upwards to point to the graduated scale under the influence of water pressure, and data can be conveniently identified.
