Measuring device for water level observation

The utility model discloses a measuring device for water level observation. The measuring device comprises a floating measuring mechanism and a deviation rectifying structure, the floating measurement mechanism is used for providing a floating plate as a reference object for water level measurement, a supporting frame is arranged on the side edge of the floating plate, and the floating plate is limited in the supporting frame through a limiting bolt; the deviation rectifying structure comprises a calibration part and a separation monitoring element, the separation monitoring element is used for detecting the floating state of the floating plate, and the calibration part is used for driving the floating plate to move to the area, away from the water surface, in the supporting frame through the limiting bolt according to the detection result and periodicity of the separation monitoring element so as to calibrate the floating state of the floating plate. The floating plate is periodically pushed to the position
