Description

Technical Field

[0001] The present invention relates to the technical field of geophysical exploration equipment, and particularly to an anti-interference measuring device for a geophysical magnetic method instrument. Background Art

[0002] Geophysical magnetism, namely magnetic method exploration, is one of the geophysical exploration methods. In many areas, magnetic field interference occurs because underground rocks and ores have different magnetic properties themselves. By using geophysical magnetism, it is possible to detect whether there are magnetic ores and rocks in a local area, and use instruments to discover and explore these places in order to find magnetic ore bodies and study geological structures.

[0003] A magnetic method instrument, also known as a magnetic susceptibility meter, is an important instrument applied in geological exploration. It is mainly used to measure the magnetic susceptibility of outcropping rocks, and perform rapid scanning of hand-sampled or core magnetization coefficients. The magnetic method instrument is easy to operate, has single-button operation, automatic calculation, and is sensitive and accurate.

[0004] Since each time the magnetic method instrument is used for measurement, the magnetism generated during measurement will remain inside the magnetic method instrument, which may affect the accuracy of the next measurement result. Moreover, under the long-term influence of the residual magnetism, it will directly lead to a reduction in the lifespan of the magnetic method instrument, causing losses. Summary of the Invention

[0005] The present invention discloses an anti-interference measuring device for a geophysical magnetic method instrument, aiming to solve the technical problem of the influence of residual magnetism on the magnetic method instrument.

[0006] To achieve the above object, the present invention adopts the following technical solution:

[0007] An anti-interference measuring device for a geophysical magnetic method instrument, including a geophysical magnetic method instrument. A plurality of interfaces are provided on one side of the geophysical magnetic method instrument. The bottom end of the geophysical magnetic method instrument is connected to a bottom body, and the bottom end of the bottom body is connected to a base. An alternating current generator is provided on one side of the geophysical magnetic method instrument, and a control button is provided on the top end of the alternating current generator. A groove is provided at the bottom end of the bottom body, and a partition is provided on the inner wall of the groove. One side of the alternating current generator is connected to a connecting wire, and the connecting wire passes through the bottom body. One end of the connecting wire is connected to a coil. A plurality of springs are provided on both sides of the coil, and the plurality of springs are simultaneously connected to the inner wall of the groove. A second fixing ring is clamped on the outer wall of one side of the coil. A clamping ring is connected to the outer wall of one side of the second fixing ring. A clamping block is sleeved on the inner wall of the clamping ring. A support rod is connected to one side of the clamping block, a turbine is connected to one side of the support rod, a screw rod is movably connected inside the turbine, and a plurality of limiting columns are connected to the bottom end of the partition.

[0008] By setting an alternating current generator, after the geophysical magnetic method instrument is used, the alternating current generator is started through the control button, so that the alternating current passes through the connecting wire to make the coil carry alternating current. Then, the turbine moves on the screw rod, and thus drives one end of the coil to move inwards through the support rod, the clamping block and the clamping ring. When the two sides of the coil contact the limit posts, the turbine slowly returns to its original position on the screw rod, and under the action of the spring, the coil is restored. Therefore, during the movement process, the coil can cover the bottom end of the partition board, and the partition board absorbs the residual magnetism inside the geophysical magnetic method instrument. Then, the alternating current generator is quickly powered off, so that the effect of demagnetizing the inside of the geophysical magnetic method instrument can be achieved, avoiding affecting the secondary detection. At the same time, the absorption of magnetic properties in the moving state can accelerate the absorption of magnetism and the thoroughness of magnetic absorption.

[0009] In a preferred solution, multiple said limit posts are located inside the coil and are distributed in equal numbers in opposite directions. A fixing ring is sleeved on the outer wall of the connecting wire, and the fixing ring is clamped on one outer wall of the coil. A second partition board is connected to one inner wall of the groove. An empty groove is provided in the inner wall of the second partition board. The bottom ends of multiple said limit posts are connected to the second partition board. The support rod passes through the empty groove, and the screw rod is parallel to the empty groove. Support plates are provided at both ends of the screw rod, and the support plates are arranged at the bottom end of the second partition board. The partition board includes a glass top plate. A glass column is provided at the bottom of the glass top plate. The bottom end of the glass column is connected to a glass bottom plate. A metal block is simultaneously provided at the bottom end of the glass top plate. The metal block is polygonal. The bottom end of the metal block is simultaneously connected to the glass bottom plate. The metal block and the glass column are placed alternately.

[0010] By setting the glass top plate, the glass bottom plate and the glass column, the electromagnetic in the geophysical magnetic method instrument can pass through and contact the alternating current of the coil. At the same time, when the alternating current generator is quickly powered off, the electromagnetic passes through the glass top plate and can stay in the middle between the glass top plate and the glass bottom plate, so as to fully react on the surface of the polygonal metal block, avoiding incomplete demagnetization after quickly powering off and improving the demagnetization effect.

[0011] In a preferred solution, the base includes a top plate. Multiple card slots are provided at the bottom end of the top plate. Multiple second grooves are provided on one inner wall of the card slots. Multiple second springs are provided on the inner walls of the multiple second grooves. The bottom end of the top plate is movably connected to a bottom plate. Multiple second card slots are provided at the top end of the bottom plate. One side of the multiple second springs is connected to the inner wall of the second card slot. The area of the second card slot is larger than that of the card slot. Multiple bottom pads are provided at the bottom end of the bottom plate.

[0012] By setting a second spring, the top plate and the bottom plate can be connected in an interleaved and movable manner. When in normal use, since the card slot is in direct contact with the bottom plate, it will not affect the normal placement. When the device is being transported and there is shaking, under the action of the second spring, the top plate and the bottom plate can move horizontally over a short distance, and shock absorption is carried out through the second spring, further avoiding damage to the device during transportation.

[0013] As can be seen from the above, an anti-interference geophysical magnetic method instrument measuring device includes a geophysical magnetic method instrument. A plurality of interfaces are provided on one side of the geophysical magnetic method instrument. The bottom end of the geophysical magnetic method instrument is connected to a bottom body, and the bottom end of the bottom body is connected to a base. An alternating current generator is provided on one side of the geophysical magnetic method instrument. A control button is provided on the top end of the alternating current generator. A groove is provided at the bottom end of the bottom body. A partition is provided on the inner wall of the groove. A connecting wire is connected to one side of the alternating current generator. The connecting wire passes through the bottom body. One end of the connecting wire is connected to a coil. A plurality of springs are provided on both sides of the coil. The plurality of springs are simultaneously connected to the inner wall of the groove. A second fixing ring is clamped on the outer wall of one side of the coil. A clamping ring is connected to the outer wall of one side of the second fixing ring. A clamping block is sleeved on the inner wall of the clamping ring. A support rod is connected to one side of the clamping block. A turbine is connected to one side of the support rod. A screw rod is movably connected inside the turbine. A plurality of limiting columns are connected to the bottom end of the partition. The anti-interference geophysical magnetic method instrument measuring device provided by the present invention has the technical effect of being able to demagnetize the inside of the geophysical magnetic method instrument and avoid residual magnetism from interfering with the secondary detection results.
