Description
Technical field
The utility model relates to surveying instrument technical field, specifically a kind of the earth horizontal shift meter.
Background technology
Earth deformation measurement is a kind of important means of Research on Crustal motion and Geological Hazards Monitoring thereof, and it is also significant to the observation of geodynamic study and earthquake precursors.The various development of the earth deformation surveying instrument based on ground both domestic and external is comparatively slow, and the earth displacement measuring instrument is in the horizontal direction rare especially.Measurement for displacement must based on a reference frame, and in daily life, we use ground as absolute reference frame mostly.But when causing significantly ground displacement due to earthquake sheet, this reference frame of the earth is just no longer applicable.In existing earthquake displacement is measured, mostly first by measuring ground acceleration, and indirectly obtain displacement to after its quadratic integral.But because the error in acceleration analysis can significantly increase after quadratic integral, adopt and measure the displacement drawn in this way there is relatively large deviation; Another kind of normal adopted mode is when utilizing pendulum length larger, and pendulum, to the unconspicuous characteristic of line top dynamic respond, obtains metastable absolute reference frame.But this mode also has certain deficiency, delayed response can cause extreme influence to the displacement measurement in later stage, when pendulum length lengthens simultaneously, is very easily subject to the impact of Coriolis force, therefore greatly have impact on the accuracy of displacement measurement.
Utility model content
The purpose of this utility model is to provide a kind of the earth horizontal shift meter, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of the earth horizontal shift meter, be made up of horizontal shift witness mark system, displacement transducer and vacuum (-tight) housing and horizontal seat, horizontal shift is measured absolute reference frame and is made up of top crown, bottom crown, electric field intensity regulating device and polarizable drop, described top crown and bottom crown horizontal symmetrical are placed, and at a distance of certain altitude, electric field intensity regulating device both positive and negative polarity is connected with bottom crown with top crown respectively, and described polarizable drop is located at the inner surface of bottom crown.
As further program of the utility model: institute's displacement sensors is made up of dot matrix infrared transmitter, face array photoelectric sensor and testing circuit, described dot matrix infrared transmitter and top crown are affixed, and described face array photoelectric sensor and bottom crown are affixed; Described testing circuit is connected with face array photoelectric sensor, and testing circuit connects computing machine.
