Static level gauge device combining electron microscope and digital ruler

Technical Field

The utility model belongs to the field of engineering safety monitoring, and particularly relates to a static level device combining an electron microscope and a digital ruler.

Background

The principle of using a hydrostatic level gauge to monitor the settlement displacement is that under the condition of basically same manufacturing indexes of the gauge, a plurality of the gauge are connected in series by utilizing the liquid level principle of communicating liquid and the buoyancy action of the liquid, the gauge is kept at the basic level and is arranged at different positions, and one measuring point gauge is used as a relatively immobile point (a base point can be used for correcting the elevation or settlement displacement by other means, such as optical leveling and a bimetallic gauge) to calculate the settlement displacement change of other points relative to the base point. When one measuring point generates settlement displacement (the settlement displacement is positive and the lifting is negative) and other points are not moved, according to the liquid level principle of the communicating liquid, the liquid in the barrel at the point is converged into other barrels, and the total convergence amount is the reduced total amount in other barrels. If a free float type displacement or stress sensing principle is adopted, corresponding displacement change or stress change occurs to each float, and therefore displacement change quantity of corresponding measuring points is monitored.

The current common static level sensor has an electrical method (such as a potentiometer type, a steel string frequency type) and a photoelectric method (CCD), and settlement displacement monitoring is realized by respectively adopting methods of measuring the stress of a floater and the upward and downward movement of the floater along with liquid in a barrel.
