Rotatable inclination measuring device and inclination measuring system

The utility model provides a rotatable inclinometer device which comprises a first walking mechanism, a second walking mechanism, an overturning part and a driving mechanism, the two ends of the overturning part are rotationally connected with the first walking mechanism and the second walking mechanism correspondingly, and the first walking mechanism and the second walking mechanism can drive the overturning part to move in an inclinometer pipe in the axis direction of the inclinometer pipe. The driving mechanism is connected with the overturning piece, the driving mechanism is used for driving the overturning piece, so that the two ends of the overturning piece rotate relative to the first walking mechanism and the second walking mechanism respectively, an inclination measuring sensor is arranged in the overturning piece, and the overturning piece is used for changing the orientation of the inclination measuring sensor in the inclination measuring pipe under the driving of the driving mechanism. The rotatab
