Description

Technical Field

[0001] The present application relates to the field of geological exploration technology, and in particular to a device and method for measuring the magnetic parameters of rock and ore samples used in geological exploration. Background Art

[0002] To timely understand the magnetic characteristics of rocks and minerals during high-precision magnetic surveys, guide magnetic survey work, and correctly interpret magnetic survey data, it is necessary to conduct the measurement and research of the magnetic parameters of rocks and minerals simultaneously with magnetic surveys. The magnetic parameter characteristics of rocks and minerals in the study area are the physical property prerequisites for the effectiveness of magnetic prospecting and provide an objective basis for the forward calculation and inversion interpretation of magnetic anomalies. For magnetic exploration, the main magnetic parameters of rocks and minerals are magnetic susceptibility and remanent magnetization vector (which includes magnetic susceptibility, remanent magnetization, magnetic inclination, and magnetic declination).

[0003] According to the method introduced in Appendix C of the "Technical Regulations for High-Precision Ground Magnetic Measurement" (DZ / T0071-2025), the magnetic susceptibility and residual magnetization intensity vector are measured using the Gaussian first position of a proton magnetometer. At present, the authorization announcement number CN105785292B discloses a magnetic parameter measurement device and measurement method for rock and mineral samples for geological exploration. The device includes a support plate, a support rod, an arc angle adjustment frame, an inclined plate, a specimen box, a probe, an adjustable support rod, a horizontal bubble meter, a precision pin and a laser emitter. By setting a laser emitter and an arc angle adjustment frame, the present invention can correct the inclination angle of the inclined plate of the device before measurement, thereby improving the accuracy of the specimen placement position.

[0004] However, when measuring the magnetic parameters of specimens, the working environment is usually in the field. Because the geology in the field is relatively soft, the length of the adjustment rod needs to be adjusted back and forth during the leveling process to ensure that the support plate is in a horizontal state, resulting in relatively low efficiency in measuring the magnetic parameters of the specimens.

Then, the slider is driven to slide by the second driving member to drive the foot support to rotate, so as to adjust the height of the tripod and make the tripod in a horizontal state. Then, the measuring device is installed on the tripod.

After the magnetic parameter measurement device is set up, the second mounting ring is pulled close to the outer edge of the placement plate, and then the second mounting ring is inserted into the hanging slot. The adjacent magnetic shielding cover is bonded and fixed with Velcro, thereby surrounding the components between the placement plate and the mounting plate. A magnetic shield is formed under the placement plate to reduce the impact of underground magnetic bodies on the measurement device, reduce the demanding conditions of the measurement site, and improve the measurement accuracy of the specimen's magnetic parameters. The position of the specimen on the inclined plate needs to be adjusted according to the strength of the specimen's magnetism and the distance from the measuring instrument probe. The distance between the specimen box and the measuring instrument probe is adjusted by lifting the specimen box from the placement slot and then sliding it along the length of the placement slot. When the specimen box is placed in the designed position, the specimen box is moved toward the bottom wall of the placement slot, so that the driving plate abuts the bottom wall of the placement slot and relatively enters the specimen box, and drives the driving plates on both sides to move toward the outside, so that the driving plates abut against the fixed airbags to fix the specimen box, thereby reducing the human interference caused by personnel manually fixing the specimen box, thereby improving the efficiency and accuracy of the specimen magnetic parameter measurement.

[0024] Reference Figure 2 、 Figure 6 and Figure 7In the embodiment of the present application, a mounting cavity 18 is opened in the mounting plate 4, and a rectangular frame is provided in the mounting plate 4 and in the mounting cavity 18. The rectangular frame includes four receiving plates 19. The receiving plates 19 are arranged in a rectangular shape and are spaced apart. The fixing rod 7 is provided on the receiving plates 19. The first driving member 8 is used to drive the four receiving plates 19 to slide and drive the fixing rod 7 to slide toward the inner wall of the mounting box 3. The end of the fixing rod 7 is prismatic. The inner wall of the mounting box 3 is provided with a rubber plate 20. The end of the fixing rod 7 is inserted into the rubber plate 20 to fix the mounting plate 4. Reference Figure 2 、 Figure 6 and Figure 7 The first driving member 8 includes an electric push rod 81 arranged in the installation cavity 18, and the receiving plate 19 is fixedly arranged on the output shaft of the electric push rod 81.

[0025] When fixing the mounting plate 4, the electric push rod 81 is started, and the electric push rod 81 pushes the receiving plate 19 to slide. The receiving plate 19 slides and drives the fixing rod 7 to slide. The fixing rod 7 slides and is inserted into the rubber plate 20. The operation is simple and convenient.

[0026] Reference Figure 7 and Figure 8 , when the mounting plate 4 is fixed, but the floating member 5 is immersed in water, when the water shakes, it is easy to act on the floating member 5 and the mounting plate 4, causing the mounting plate 4 to easily shake slightly. Therefore, in the embodiment of the present application, an air bag 21 is provided in the mounting plate 4 and in the mounting cavity 18. The air bag 21 is located in the rectangular frame and is fixed to the inner wall of the receiving plate 19. When the electric push rod 81 pushes the receiving plate 19 to drive the fixing rod 7 to move toward the mounting box 3, the air bag 21 is pulled to increase the volume of the air bag 21; the suction member 22 is also included. The suction member 22 is used to remove the liquid in the mounting box 3 after the fixing rod 7 is nailed into the rubber plate 20. The liquid is transferred into the airbag 21, thereby improving the stability of the mounting plate 4 and the floating member 5; when the mounting plate 4 is fixed in the mounting box 3, the liquid in the mounting box 3 is sucked into the airbag 21 by the suction member 22, and the water is temporarily stored in the airbag 21, thereby reducing the influence of water shaking on the stability of the mounting plate 4; at the same time, after the water is temporarily stored in the airbag 21, it is convenient for measuring the magnetic parameters of the specimen at the next location; at the same time, after the liquid is extracted into the airbag 21, the weight of the mounting plate 4 is increased, thereby improving the ability of the mounting plate 4 to resist shaking, further improving the stability of the mounting plate 4, and thus improving the stability of the tripod 1 and the measuring device 2.

[0027] Reference Figure 7 and Figure 8In the embodiment of the present application, the suction member 22 includes a rotating tube 221 and a liquid return tube 222. The rotating tube 221 is rotatably arranged at the bottom of the fixed rod 7. The rotating axis of the rotating tube 221 is perpendicular to the length direction of the fixed rod 7. The fixed rod 7 and the rotating tube 221 are both hollow. The liquid return tube 222 is embedded in the rotating tube 221 and the fixed rod 7 and connected to the airbag 21. The initial position of the rotating tube 221 is attached to the outer wall of the fixed rod 7. It also includes a second fixing member. The second fixing member is used to fix the rotating tube 221 to the outer wall of the fixed rod 7. After the fixing effect of the second fixing member is released, the port of the rotating tube 221 is immersed in the liquid and the liquid is sucked into the airbag 21. The liquid inlet end of the liquid return tube 222 is provided with a one-way valve. The one-way valve allows the liquid to enter the liquid return tube 222 through the liquid inlet port. Reference Figure 7 and Figure 8 Furthermore, an accommodating groove 23 is formed on the outer wall of the fixing rod 7. The accommodating groove 23 is located at the bottom of the fixing rod 7. The rotating tube 221 is hinged in the accommodating groove 23. The second fixing member includes a blocking rod 223 slidably arranged in the accommodating groove 23. The blocking rod 223 is coaxial with the rotating tube 221 and inserted into the rotating tube 221. After the blocking rod 223 is inserted into the rotating tube 221, the liquid inlet of the return liquid pipe 222 is blocked. The second fixing member also includes a third driving member for driving the blocking rod 223 to slide into or move out of the rotating tube 221. Reference Figure 7 and Figure 8 The third driving member includes a driving rod 224 slidably arranged in the fixed rod 7, the driving rod 224 is located on the prismatic end surface of the fixed rod 7, the driving rod 224 is parallel to the blocking rod 223, and an intermediate rod 225 is arranged between the driving rod 224 and the blocking rod 223. The intermediate rod 225 is hinged in the fixed rod 7, and the hinge axis of the intermediate rod 225 is perpendicular to the axial direction of the fixed rod 7. The ends of the blocking rod 223 and the driving rod 224 are slidably arranged on the intermediate rod 225, and 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, when the driving rod 224 abuts the rubber plate 20, it pushes the intermediate rod 225 to rotate, and the rotation of the intermediate rod 225 drives the blocking rod 223 to slide.

[0028] When the fixing rod 7 slides out from the mounting plate 4, the fixing rod 7 is inserted into the rubber plate 20. When the driving rod 224 contacts the rubber plate 20, the driving rod 224 relatively enters the fixing rod 7. The driving rod 224 drives the intermediate rod 225 to rotate. The rotation of the intermediate rod 225 drives the blocking rod 223 to slide. The blocking rod 223 slides toward 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 of the rotating tube 221, the rotating tube 221 rotates toward the liquid direction, so that the end of the rotating tube 221 is immersed in the liquid. Subsequently, under the action of the negative pressure of the airbag 21, the liquid is drawn from the mounting box 3 into the airbag 21.

[0029] Reference Figure 9 In order to expand the volume of the airbag 21, a plurality of cross bars 24 are provided in the airbag 21. The cross bars 24 are telescopic rods and are parallel to each other.
