Description
Technical field
The utility model relates to a kind of plumb line coordinator of monitoring the dam displacement amount, and the displacement that is particularly useful for the long term monitoring dam under the rugged surroundings changes, and belongs to hydraulic structure or municipal works displacement (or amount of deflection) surveying instrument field.
Background technology
The plumb line coordinator that is used for the monitoring of dam displacement amount both at home and abroad has types such as step motor type, CCD photo-electric and condenser type, and its measuring accuracy and measurement range can satisfy request for utilization substantially.But relatively moister, drip, all there is to a certain degree environmental suitability problem in long-term down its reliability of using in the dam engineering of rugged surroundings such as many dirt.
The utility model content
The utility model wants the technical solution problem to be: overcome existing plumb line coordinator in the not high defective of reliability relatively moister, that drip, exist in the severe environment applications such as many dirt, a kind of inductive plumb coordinator of novel dam displacement amount monitoring is provided.
In order to solve above technical matters, inductive plumb coordinator of the present utility model, it is characterized in that comprising: be fixed on the inductor on the vertical line body, described inductor have the cylindrical hollow insulating carrier and with its fixing magnetic material, described magnetic material evenly distributes around the center line of cylindrical hollow insulating carrier, it is external that described inductor is enclosed within vertical line, the X of described inductor respectively is provided with a pair of coil to both sides, Y to both sides, inductor X is connected to signal converter with X to the coil of both sides, and inductor Y is connected to signal converter with Y to the coil of both sides.
The utility model adopts magnetic induction principle and variate structure, realizes the non-cpntact measurement of dam body or buildings displacement variable, improves the plumb line coordinator adaptive capacity to environment.Concrete principle is, inductor X is to, Y two groups of coils and the signal converter to both sides, and a public inductor forms difference structure.When measuring point during with respect to vertical line generation relative displacement, inductor moves between two groups of coils with vertical line.Signal converter energising output high-frequency signal injection coil during measurement, when the close coil of inductor change in displacement, coil inductance increases, and the signal converter output frequency is reduced; When inductor X to Y to away from coil, coil inductance reduces, and the signal converter output frequency is increased.The position that the frequency-splitting of the coil by monitoring inductor both sides can be measured vertical line.And directly displacement is converted to the electrical measurement frequency signal, and both improved antijamming capability, prolonged signal transmission distance again.
In addition, insulating carrier of the present utility model has one and holds the open slot that the vertical line body penetrates, and is convenient to on-the-spot the installation, is more conducive to applying of the utility model plumb line coordinator.
Obviously, the utility model inductive plumb coordinator ingenious conception, the measuring accuracy height has stronger environment interference, be suitable for various rugged surroundings, especially can moist, drip, carry out the monitoring of dam displacement amount stably in a long term under the environment such as many dirt.After estimating to release, will be subjected to people's popular welcome, have good market outlook.

Embodiment
The inductive plumb coordinator of present embodiment as shown in Figure 1 and Figure 2, it comprises: be fixed on the inductor 1 on the vertical line body 10, described inductor 1 have cylindrical hollow insulating carrier 11 and with its fixing magnetic material 12, described magnetic material 12 evenly distributes around the center line of cylindrical hollow insulating carrier 11, inductor 1 is enclosed within outside the vertical line body 10, (after the installation, the central lines of the center line of hollow insulating carrier and vertical line body makes magnetic material around the peripheral evenly distribution of vertical line body).The X of inductor 1 respectively is provided with a pair of coil to both sides, Y to both sides, and (5 is that Y is to coil former among Fig. 1,2 be X to a coil former, another X does not draw to coil former), inductor X is connected to signal converter 3 with X to the coil of both sides, and inductor Y is connected to signal converter (not drawing among the figure) with Y to the coil of both sides.In this example, as shown in Figure 2, along the even some elongated slots that distribute of the circumference of cylindrical hollow insulating carrier 11, (magnetic material of the present utility model can be selected ferrite magnetic material for use to magnetic material 12, in the present embodiment, adopt MDX2000) be strip and embed in this elongated slot, magnetic material 12 is all equal to the distance of vertical line body 10, realize that as far as possible inductor evenly distributes along the magnetic field of circumference, improve the stability of instrument.
As shown in Figure 1, inductor X to coil by X be fixed on to coil former 2 be positioned at the measured point X on fixed base plate 4, inductor Y to coil by Y be fixed on to coil former 5 be positioned at the measured point Y on fixed base plate 6.Among the figure, 7 is every post, be supported in X to fixed base plate 4 and Y between fixed base plate 6; 9 is erecting frame, Y to 6 of fixed base plates on this erecting frame; 8 are the protection outer cover.
When measuring point during with respect to vertical line generation relative displacement, inductor moves between two groups of coils with vertical line.Signal converter energising output high-frequency signal injection coil during measurement, the inductor change in displacement changes the inductance of coil, and the frequency of signal converter output is changed.The position that the frequency-splitting of the coil by monitoring inductor both sides can be measured vertical line.This device is converted to the electrical measurement frequency signal with displacement, has both improved antijamming capability, has prolonged signal transmission distance again.
Install for the ease of the scene, insulating carrier 11 has the open slot 13 that an appearance vertical line body 10 penetrates as shown in Figure 2.When inductor is installed, the open slot of insulating carrier is aimed at the vertical line body, make the vertical line body penetrate insulating carrier, like this, the vertical line body passes through the hollow chamber in insulating carrier, inductor is fixed with the vertical line body promptly finished installation at last.
Principle such as Fig. 3 of the signal converter of this plumb line coordinator show, constitute LC bikini oscillator resonant circuit by coil (inductance) L1 (or coil L2), capacitor C 1 and capacitor C 2, and constitute positive feedback by capacitor C 0 and triode T1; Resonance wave amplifies output through operational amplifier A 1, increases signal transmission distance.This signal converter is used relay switch KA1 and is switched between two coil L1 and L2, forms the differential structure of these two public one group of oscillator electronics of coil.Consistance all takes place changing when external environment changes the output frequency that causes two groups of coils when causing electron device performance change in the resonant circuit, can effectively eliminate external environment by two class frequency differences of output and change the error of bringing.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
