Description

TECHNICAL FIELD

[0001] The application relates to the technical field of geological exploration, in particular to a rock and mineral specimen magnetic parameter measuring device and method for geological exploration. BACKGROUND

[0002] In order to understand the magnetic characteristics of rock and mineral in time during high-precision magnetic measurement, guide the magnetic measurement work and correctly interpret the magnetic measurement data, it is necessary to determine and study the magnetic parameters of rock and mineral while carrying out the magnetic measurement work. The magnetic parameter characteristics of rock and mineral in the study area are the physical prerequisites for whether the magnetic prospecting exploration is effective, and are the objective basis for the forward calculation and inversion interpretation of the magnetic anomaly, and have the basic significance. For the magnetic prospecting exploration, the magnetic parameters of rock and mineral mainly include the magnetic susceptibility and the residual magnetization strength vector (which includes the magnetic susceptibility, the residual magnetization strength, the magnetic inclination and the magnetic declination).

[0003] According to the method introduced in Appendix C of the Technical Regulation for Ground High-precision Magnetic Measurement (DZ / T0071-2025), the magnetic susceptibility and the residual magnetization strength vector are determined by the first position of the proton magnetic force meter. At present, for example, the rock and mineral specimen magnetic parameter measuring device and method for geological exploration disclosed in the authorized announcement No. CN105785292B includes a support plate, a support rod, an arc angle adjusting frame, an inclined plate, a specimen box, a probe, an adjustable support rod, a horizontal bubble instrument, a precision pin shaft and a laser emitter. The device can correct the inclination angle of the inclined plate of the device before measurement, and improve the accuracy of the specimen placement position by setting the laser emitter and the arc angle adjusting frame.

[0004] However, when measuring the specimen magnetic parameters, the working environment is usually in the field. Because the geology in the field is soft, the length of the adjusting rod needs to be adjusted back and forth during the leveling process, so as to ensure that the support plate is in a horizontal state, thereby causing the specimen magnetic parameter measurement efficiency to be general.

[0063] With reference to Figure 7 and Figure 8 In the embodiment of the application, the suction piece 22 comprises a rotating pipe 221 and a liquid return pipe 222, the rotating pipe 221 is rotatably arranged at the bottom of the fixed rod 7, the rotating axis of the rotating pipe 221 is perpendicular to the length direction of the fixed rod 7, the fixed rod 7 and the rotating pipe 221 are hollow, the liquid return pipe 222 is embedded in the rotating pipe 221 and the fixed rod 7 and connected into the air bag 21, the initial position of the rotating pipe 221 is attached to the outer wall of the fixed rod 7, further comprising a second fixing piece for fixing the rotating pipe 221 to the outer wall of the fixed rod 7, after the second fixing piece is released, the port of the rotating pipe 221 is immersed in the liquid to suck the liquid into the air bag 21, the liquid inlet end of the liquid return pipe 222 is provided with a one-way valve, the one-way valve allows the liquid to enter the liquid return pipe 222 through the liquid inlet port;

[0064] With reference to Figure 7 and Figure 8 Further, the outer wall of the fixed rod 7 is provided with a containing groove 23, the containing groove 23 is located at the bottom of the fixed rod 7, the rotating pipe 221 is hingedly connected in the containing groove 23, the second fixing piece comprises a blocking rod 223 which is slidingly arranged in the containing groove 23, the blocking rod 223 is coaxial with the rotating pipe 221 and is inserted into the rotating pipe 221, after the blocking rod 223 is inserted into the rotating pipe 221, the liquid inlet of the liquid return pipe 222 is blocked, the second fixing piece further comprises a third driving piece for driving the blocking rod 223 to slide into or out of the rotating pipe 221;

The end of the driving rod 224 is slidably arranged on the intermediate rod 225. The end of the driving rod 224 is located outside the end of the fixed rod 7. When the fixed rod 7 enters the rubber plate 20, the intermediate rod 225 is pushed to rotate when the driving rod 224 abuts against the rubber plate 20. The rotation of the intermediate rod 225 drives the blocking rod 223 to slide.

[0066] When the fixed rod 7 is pulled out of the mounting plate 4 and inserted into the rubber plate 20, the driving rod 224 is relatively inserted into the fixed rod 7 when the driving rod 224 contacts the rubber plate 20.

The blocking rod 223 slides towards the outside of the rotating tube 221 and moves out of the rotating tube 221, thereby releasing the fixation of the rotating tube 221. Subsequently, under the action of gravity, the rotating tube 221 rotates towards the liquid direction, so that the port of the rotating tube 221 is immersed in the liquid. Subsequently, under the action of the negative pressure of the air bag 21, the liquid is extracted from the mounting box 3 into the air bag 21.

[0067] With reference to Figure 9 In order to expand the increased volume of the air bag 21, a plurality of cross rods 24 are arranged in the air bag 21. The cross rods 24 are telescopic rods and parallel to each other. The two ends of the cross rods 24 are respectively fixed on the inner wall of the air bag 21. When the electric push rod 81 drives the receiving plate 19 to move, the volume of the air bag 21 is increased. At this time, the air bag 21 pulls the cross rods 24 to elongate and supports the top and bottom of the air bag 21, thereby further increasing the volume of the air bag 21 and facilitating the extraction of the liquid into the air bag 21.

[0068] With reference to Figure 10 And Figure 11 The magnetic isolation device 25 is used to form a magnetic shield below the placement plate 12 to reduce the influence of magnetism on the measuring device 2.
