the other is a water level observer adopting a floater and a scale rod, and the water level data is recorded by manually reading the scale on the scale rod, but the scale rod is independently exposed outside when the underground water level rises, so that the external wind force blows on the scale rod to cause the problem of left and right shaking, the indication position of the scale rod is not fixed, the data of the water level is read, the precision is reduced, and the scale rod is broken and bent due to the wind.

For example, the utility model of CN215832810U discloses a groundwater level observing device, although the top end of the observing post movably passes through the fixed sleeve seat of the observing post and extends to the outside of the top end of the cylindrical sleeve, the positioning effect of the observing post on the observing post in the lifting process along with the rising of the water level can be achieved, so that the observing post is more stable in rising, the problem of inaccurate water level data caused by unstable shaking when the observing post rises is avoided, and the problem that the observing post is broken, bent and scrapped due to the influence of external wind can be avoided, but the following disadvantages still exist;

firstly, in order to ensure that the observation post can smoothly ascend, the fixed sleeve seat and the observation post can have too great friction, so that the limiting effect of the fixed sleeve seat is limited;

secondly, the sleeve seat is fixed on the ground through the cylindrical sleeve, but the height is not low, and in windy weather, the sleeve seat has larger wind resistance and any toppling risk.
