[0031] When measuring the water level under the bridge, the translation block 3 is driven to move by the translation mechanism to facilitate the measurement of the water levels of different waters under this bridge section. The lifting mechanism can drive the horizontal plate 4 to fall on the water surface. The setting of the air cushion 17 can avoid the horizontal plate 4 from sinking into the water as much as possible. The telescopic mechanism can drive the starting end of the tape measure 6 to spread into the water. When the connecting block contacts the bottom of the water, the telescopic mechanism cannot continue to extend. At this time, the telescopic mechanism stops working and the staff can record the value of the tape measure later.
