Description
Technical field
The present invention relates to magnetic probe technical field, is popped one's head in more particularly to a kind of axis fluxgate of spherical three.
Background technology
The principle of magnetic survey technology is periodically to be in magnetic saturation state by periodic alternating magnetic field magnetic core, profit
Electric signal output is converted into by environmental magnetic field to the modulating action of excitation field with magnetic core.It is true by the analysis to induced electromotive force
Determine the size of environmental magnetic field.
The magnetic core of magnetic probe mainly has three kinds of toroidal core, single rod type magnetic core and double stick type magnetic core structures at present.Using list
Rod type magnetic core, detection coiling not only have the induced electromotive force after environmental magnetic field is modulated, can also there is transformer action sensing
Electromotive force.Transformer action induced electromotive force turns into magnetic probe noise, and intensity is sufficiently large, or even can flood effective induction electric
Gesture., can eliminating transformer effect sense by excitatory coiling in opposite direction around the home on two rod type magnetic cores using double stick type magnetic core
Electromotive force is answered, but unidirectional magnetic field intensity can only be detected.Using toroidal core, performance is compared with single rod type magnetic core and double stick type magnetic core
It is good, but unidirectional magnetic field intensity can only be detected.
The magnetic core of above-mentioned three kinds of structures using when be by three mutually isostructural discrete magnetic core structures along X, Y, Z axis direction
Into because magnetic core must be positioned at the center for detecting coiling, discrete magnetic core can not meet to require, environment magnetic can be caused reluctantly by placing
The three-component of field influences each other, and reduces the degree of accuracy of magnetic probe.
Publication No. is that CN102928885A patent discloses a kind of " full tensor of spherical feedback three-component fluxgate magnetic gradient
Probe ", the magnetic gradiometer of the patent feed back coiling, each axle coiling around the home by the way of the fluting of spherical feedback bobbin surface
The groove width of groove is identical, and multiturn coil, separation are identical around the home for each groove.Because the coil turn in each groove around the home is multiturn, therefore
The problems such as not being preferable lamination flush system around the home be present between turn-to-turn and cable shunt capacitance and coil so that the detection of three axles
The inductive impulse that coiling collects is undesirable, reduces the degree of accuracy of magnetic survey.The spherical feedback bobbin of the patent passes through red
The cutting of road face is adhered by into two, during use, it is long-term use of after two hemispheres bonding place space easily be present, cause two hemispheres
Spacing between the winding slot of the equatorial plane is more than the separation of design so that and the regularity of distribution of feedback magnetic field is more complicated,
Reduce the reliability of feedback magnetic survey.

Embodiment
Embodiment
As shown in Figure 1 to 4, the present invention includes without magnetic core 1, detection bobbin 2, feedback bobbin 3 and swashed
Magnetic coiling, detection coiling and feedback coiling, the no magnetic core 1 is mutual along X-axis, Y-axis, Z-direction by three square rings
Orthogonal formation, three square rings are formed by the compacting of magnetic conduction thin slice and thickness is identical with size, more around being equipped with no magnetic core 1
The excitatory coiling of circle.
It is machined with the detection bobbin 2 along X-axis, Y-axis, Z-direction and mutually orthogonal groove 21, detects coiling
Around the home in groove 21, no magnetic core 1 is arranged in the inner chamber of detection bobbin 2, no magnetic core 1 and detection bobbin 2
X-axis, Y-axis, Z axis it is coaxial.
The feedback bobbin 3 is spherical in shape, feed back be carved with bobbin 3 it is a plurality of it is wide, contour and not etc. deep three
Axle winding slot 32 (the axle winding slot of X, Y, Z tri- is mutually orthogonal), each winding slot 32 respectively along the respective equatorial plane (equatorial plane refer to
That disc that axle is vertical and diameter is maximum) it is symmetrical arranged, feedback coiling is single-turn circular coil, and feeds back coiling around the home in winding slot
In 32, the influence of the uncontrollable factor such as electric capacity and coil canoe can be evaded using single-turn circular coil, gathers detection coiling
The inductive impulse arrived is more preferable, so as to improve the degree of accuracy of magnetic survey.The present invention also feedback bobbin 3 inside be provided with along X-axis,
The through hole 33 of Y-axis, Z-direction, the both ends of through hole 33 are provided with detachable spherical cap 31, and detection bobbin 2 (has been installed in inner chamber
Without magnetic core 1) it can be put into by opening from through hole 33 to the center of feedback bobbin 3 after detachable spherical cap 31.It is removable
The outer face for unloading spherical cap 31 is plane, it is ensured that attitude stabilization when magnetic probe works, and feedback coiling can be put into bobbin 2
As base station during skeleton 3, to facilitate bobbin 2 to be put into.Detect bobbin 2 and feed back the X-axis, Y-axis, Z axis of bobbin 3
Coaxially.
Mode makes geomagnetic survey system form closed-loop system around the home for above-mentioned feedback coiling of the present invention, and feedback coiling produces
Uniform feedback magnetic field, no magnetic core 1 is operated in null field state, improve the linearity and stability of magnetic survey.Spherical structure
Feedback coiling make again caused by field homogeneity scope it is bigger, the degree of accuracy of Measurement of environmental magnetic field can be improved.
The direction of magnetization of no magnetic core 1 of the present invention is along the direction of square ring, i.e., along 4 of square ring
The direction on side, in the state of magnetic conductance is logical, 4 sides of the three square rings set in no magnetic core 1 along X-axis, Y-axis, Z axis
