Embodiment Construction

[0012] The inductive vertical line coordinate instrument of the present embodiment is as figure 1 , figure 2 As shown, it includes: an induction body 1 fixed on a vertical body 10, the induction body 1 has a cylindrical hollow insulating carrier 11 and a magnetic material 12 fixed thereto, and the magnetic material 12 wraps around the cylindrical hollow insulating carrier 11 The center line of the center line is evenly distributed, and the induction body 1 is set outside the vertical line body 10. A pair of coils ( figure 1 Middle 5 is the coil frame in the Y direction, 2 is a coil frame in the X direction, and the other coil frame in the X direction is not shown), the coils on both sides of the induction body X are connected to the signal converter 3 in the X direction, and the Y direction of the induction body is connected to the two sides. The coil on the side is connected with the Y-direction signal converter (not shown in the figure). In this example, if figure 2 As...

Abstract

The invention discloses an inductive plumb coordinator, which is characterized by comprising an inductor fixed on a plumb body. The inductor has a hollowly cylindrical insular carrier and a magnetic material fixed with the same; the magnetic material is uniformly distributed around the central line of the hollowly cylindrical insular carrier; the inductor is sleeved outside the plumb body; the two sides in X direction and the two sides in Y direction of the inductor are provided with a pair of coils respectively; the coils on the two sides in X direction of the inductor are connected with a signal converter in X direction, while the coils on two sides of Y direction are connected to a signal converter in Y direction. The inductive plumb coordinator of the invention has the advantages of ingenious design, high measuring precision and relatively strong resistance to environmental interference; the inductive plumb coordinator is suitable for various severe environments and particularly is capable of reliably monitoring the dam displacement for a long time in humid, water-dropping and dusty environments and the like. The inductive plumb coordinator is expected to be popular and have a good market prospect after being launched.

Description

technical field [0001] The invention relates to a vertical line coordinate instrument for monitoring the displacement of a dam, which is especially suitable for long-term monitoring of the displacement change of the dam in harsh environments, and belongs to the field of displacement (or deflection) measuring instruments for hydraulic structures or municipal engineering. Background technique [0002] The vertical line coordinate instruments used for dam displacement monitoring at home and abroad include stepper motor type, CCD photoelectric type and capacitive type, and their measurement accuracy and measurement range can basically meet the requirements of use. However, there is a certain degree of environmental adaptability in the long-term use of dam projects in harsh environments such as humidity, dripping water, and dust. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the defects of low reliability existing...
