Water level monitoring device for water conservancy project

The invention relates to a water level monitoring device for a water conservancy project. The device comprises a vertical plate, a liquid level meter and a control box; the front face of the vertical plate is provided with a first supporting mechanism for extending the liquid level meter to the position above a river channel; the vertical plate is provided with a buffering mechanism for buffering the first supporting mechanism; and the bottom of the vertical plate is provided with a second supporting mechanism for supporting the vertical plate; and a reinforcing mechanism for assisting in fixing the second supporting mechanism is arranged in the second supporting mechanism. According to the water level monitoring device of the invention, a cross bar and a liquid level gauge can be supported by a rotating shaft in the first supporting mechanism, and the cross bar can rotate around the rotating shaft, so that the liquid level gauge can rotate from the upper part of the river channel to the edge of the river cha
