Description

Technical Field

[0001] The present invention relates to the technical field of geological drilling and exploration, and more particularly to an exploration device for geological investigation. Background Art

[0002] Mineral exploration is an important part of geological surveys. Currently, magnetic detection has been widely used in it. Direct prospecting is carried out based on the characteristics of useful minerals in ores that are magnetic or that magnetic minerals coexist with them, or indirect prospecting is carried out based on the characteristics of the ore body in its genesis or space that is related to the structure of certain magnetic geological bodies. These mines include iron ore, lead-zinc ore, copper ore, etc. In conjunction with mining area exploration, the depth, occurrence and continuity of the ore body are studied, as well as the shape and size of the ore body, the scale of the deposit is estimated, engineering surveys, environmental exploration, hydrology, oil and natural gas exploration, and geological structure and tectonic issues related to oil and gas are studied.

[0003] In the process of using proton magnetometers to detect minerals, since most minerals are located at great depths, drilling is required. That is, the proton magnetometer probe is lowered into the borehole to measure the magnetic field of the rock formations around the borehole wall. However, the existing detection methods make it difficult to effectively combine drilling and magnetic measurement. They need to be carried out separately using independent equipment, which is more troublesome. In addition, mud liquid seeping from the surrounding soil layers will remain in the borehole. On the one hand, the presence of mud will generate great viscous resistance, affecting the propulsion of the probe. On the other hand, minerals such as magnetite and hematite (from the formation or additives) are mixed in the drilling mud. These particles will generate additional magnetic fields, interfering with the probe's measurement of the true geomagnetic field. At present, the above problems have not been effectively solved in the application of magnetic detection in geology. Summary of the Invention

[0014] The beneficial effects of the present invention are:

[0015] The present invention constructs a set of operating modes of "ground magnetic measurement to locate anomalies" - "drilling verification" - "in-hole magnetic measurement and fine detection". This exploration method, which organically combines horizontal and vertical directions, utilizes the function of the conversion module to effectively combine drilling work and magnetic measurement work, forming a magnetic measurement method that first conducts preliminary positioning and then precise positioning, effectively avoiding blind drilling, reducing exploration costs, and significantly improving the overall efficiency of magnetic measurement work.

[0016] The function of the protective part in the present invention is carried out synchronously with the propulsion of the magnetic measurement module. When the magnetic measurement module penetrates into the borehole, mud enters from the bottom of the sleeve. At the same time, the gear moves downward and rotates with the cooperation of the rack, so that the shaft drives the blade to rotate, and a vacuum is briefly formed around the blade, thereby generating suction at the suction pipe, which continuously sucks out the mud entering the sleeve, reducing the resistance of the probe to the mud when it is pushed forward, until the sleeve is against the bottom of the hole. Since most of the mud in the sleeve is sucked out, it will not form a cover around the probe. The probe can work without being interfered by the mud, and obtain real and effective detection data.

[0017] The proton magnetometer used in the present invention has a different principle from other types of magnetometers. It belongs to a branch of magnetometers with higher precision. Even when measuring weak magnetic objects, such as the Earth's magnetic field, it can still achieve high resolution and accuracy. Therefore, even weak changes in the Earth's magnetic field can be detected. Its working principle is to use the precession phenomenon of hydrogen protons in the magnetic field for measurement. The sensor is filled with hydrogen-containing liquid. Before being forcibly polarized by the instrument, these hydrogen protons are in a disorderly arrangement state. When a polarization signal is artificially added to them, the protons will perform precession motion. After the polarization signal disappears, the precession of the protons will be mainly affected by the external magnetic field and will gradually disappear. By measuring the frequency in the sensor affected by the precession, the magnitude of the external magnetic field can be detected. By continuously repeating this action, continuous measurement can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0038] The present invention discloses a geological survey exploration device, such as Figure 1 - Figure 10 As shown, it includes a trolley 1, a support module 2, an electric push rod 3, a conversion module 4, a drilling module 5, a magnetic measurement module 6, a protective member 7 and a magnetic measurement host 8. The electric push rod 3 is hoisted above the trolley 1 through the support module 2, and the propulsion direction is vertical. On the one hand, it provides a coordinated lifting effect when the drilling module 5 is drilling, and on the other hand, it is used to pull the magnetic measurement module 6 into or out of the borehole. The conversion module 4 is fixedly provided on the support module 2. The conversion module 4 is arranged in conjunction with the drilling module 5 and the magnetic measurement module 6 to drive the drilling module 5 and the magnetic measurement module 6 to be alternately fastened to the output end of the electric push rod 3. Figure 2 The form of the arrangement is that the electric push rod 3 is fixed in position, and the drilling module 5 and the magnetic measurement module 6 are in a circular rotating plane that can switch positions;

[0039] When conducting mineral exploration, the magnetic measurement module 6 follows the cart 1 to move in the ground magnetic measurement to find data anomalies, and a borehole is opened at the data anomaly point through the drilling module 5, and then the magnetic measurement module 6 is switched to enter the borehole for vertical magnetic measurement. The magnetic measurement module 6 is equipped with a protective part 7, and the mud in the borehole is synchronously sucked when the magnetic measurement module 6 moves downward. The cart 1 is fixed with a magnetic measurement host 8 electrically connected to the magnetic measurement module 6. Corresponding to the above, the magnetic measurement host 8 writes a parameter warning program, that is, a certain parameter range is preset, and an alarm is automatically triggered when the range is exceeded, and a flash light or buzzer is used in conjunction with it. When finding data anomalies during the ground magnetic measurement process, the parameter warning program is triggered, and the flash light or buzzer works, which can effectively remind the operator to mark the corresponding point.

[0040] In specific implementation, through the above-mentioned settings of the present invention, the operator can construct a set of "ground magnetic measurement positioning anomaly" - "drilling verification" - "in-hole magnetic measurement fine detection" operation methods, that is, first divide the area to be surveyed into several points at equal intervals, and then do not activate the drilling module 5 first, only use the cart 1 to carry the magnetic measurement module 6 to conduct preliminary surveys at each point in the horizontal direction. When the point with abnormal data is located, use the drilling module 5 to open a borehole at the location, and then switch the magnetic measurement module 6 to docking with the electric push rod 3 through the conversion module 4, and use the electric push rod 3 to push the magnetic measurement module 6 into the borehole for vertical fine magnetic measurement.

[0041] This exploration method that organically combines horizontal and vertical directions, utilizing the function of conversion module 4, can effectively combine drilling work and magnetic survey work, forming a magnetic survey method that first performs preliminary positioning and then accurately positions, effectively avoiding blind drilling, reducing exploration costs, and significantly improving the overall efficiency of magnetic survey work.

[0042] The support module 2 includes a base 201, a bracket 202, a top plate 203, a through hole 204, a slider 205, a diagonal support leg 206, a threaded sleeve 207 and a second stud 208. The base 201 is fixedly provided on one side of the cart 1. The base 201 is slightly higher than the plane where the wheels of the cart 1 are located. Brackets 202 are upright and fixed at the four corners of the base 201. The bracket 202 is L-shaped, including a horizontal part and a vertical part. The horizontal part is arranged along the diagonal of the base 201. The top center of the four groups of brackets 202 is fixed with a top plate 203. An electric push rod 3 is inserted and fixed on the top plate 203. The center of the base 201 is provided with a push rod 3. The through hole 204 is matched with the through hole 204, and the size of the through hole 204 is set to be larger than the overall size of the combination of the magnetic measurement module 6 and the protective member 7 to ensure that it can pass smoothly. The bracket 202 is provided with a slider 205, and the slider 205 is fixedly provided with an oblique support leg 206. The end of the oblique support leg 206 is provided with a hollow threaded sleeve 207, and the threaded sleeve 207 is threadedly connected with a second stud 208. The oblique support leg 206 is inclined at an acute angle compared to the bracket 202, and the second stud 208 is also inclined at an acute angle compared to the oblique support leg 206, and the contact end of the oblique support leg 206 with the ground is straightened, so that compared with the ordinary support structure, an additional support point is obtained, which is more stable.

[0043] The support module 2 provides a stable support for the electric push rod 3 during drilling and precise magnetic measurement. When drilling is required, the diagonal support legs 206 are Figure 3 As shown, the base 201 is unfolded at the four corners, and then the second studs 208 are screwed in to press them into the soil to form a stable four-corner support structure.

[0044] A slide groove 2021 is provided in the bracket 202, and the slider 205 slides in cooperation with the slide groove 2021. The thickness of the slider 205 is slightly larger than the slide groove 2021. A splint 2051 is fixedly provided on the slider 205. The splint 2051 semi-encloses the side of the bracket 202 and does not affect the sliding of the slider 205 relative to the slide groove 2021. A first stud 2052 is threadedly connected to the splint 2051, and the first stud 2052 abuts against the bracket 202 after being tightened.

[0045] The diagonal support leg 206 has an adjustable feature by sliding cooperation between the slider 205 and the slide groove 2021. When there is a drop on the ground, the slider 205 can be slid first to adjust the azimuth angle of the diagonal support leg 206, and then the diagonal support leg 206 can be locked by screwing in the first stud 2052, and then the bottom of the diagonal support leg 206 can be tightened as described above.

[0046] The support module 2 further includes a support plate 209, such as Figure 2As shown, the support plate 209 is fan-shaped, and the curvature of the fan matches the circular trajectory formed by the drilling module 5 and the magnetic measurement module 6 when they rotate, thereby providing the support plate 209 with a sufficient bearing surface while minimizing the material. The support plate 209 is suspended above the base 201 by several pillars, and the support plate 209 alternately fits with the drilling module 5 and the magnetic measurement module 6.

[0047] When the drilling module 5 and the magnetic measurement module 6 are alternately docked with the electric push rod 3, the support plate 209 provides temporary support to the module that is not docked with the electric push rod 3 without affecting the rotation switching, which cooperates with the function that the electric push rod 3 needs to slightly deflect the conversion module 4 before advancing to make the clamping column 404 disengage from the opening clamping plate 406.

[0048] The conversion module 4 includes a conversion motor 401, a connecting plate 402, an end block 403, a clamping column 404, a joint 405, a perforated clamping plate 406, a chuck 407 and a fastening screw 408. The conversion motor 401 is fixedly provided on the base 201, and the end block 403 is symmetrically fixedly provided on the output end of the conversion motor 401. The clamping column 404 is fixedly installed on the end block 403, and the clamping columns 404 on the two end blocks 403 are in opposite directions. The drilling module 5 and the magnetic measurement module 6 are both fixedly provided with a perforated clamping plate 406 that cooperates with the clamping column 404. The output end of the electric push rod 3 is fixedly provided with a chuck 407, and the chuck 407 is threadedly connected with a fastening screw 408. The top of the drilling module 5 and the magnetic measurement module 6 are both fixedly provided with a joint 405 that cooperates with the fastening screw 408.

[0049] When the conversion module 4 is implemented, the connection plate 402 is driven to rotate by the conversion motor 401, and the cooperation between the clamping column 404 and the hole clamping plate 406 is used to realize the pushing of the drilling module 5 and the magnetic measurement module 6, so that they are alternately aligned with the active end of the electric push rod 3. After alignment, the fastening screw 408 is screwed in. During the screwing process, it first passes through the joint 405 to form a connection, and then rests against the inner wall of the chuck 407 for fixation. The same applies when it needs to be disassembled.

[0050] The conversion module 4 also includes a pointer 409 and a code disk 410. The pointer 409 floats above the code disk 410. The pointer 409 is fixedly set on the top of the end block 403. The code disk 410 is fixedly set on the base 201. The code disk 410 is circular and has readings marked at 90 degree intervals, namely 0 degree, 90 degrees, 180 degrees and 270 degrees.

[0051] The cooperation between the pointer 409 and the code disk 410 serves to switch the drilling module 5 and the magnetic measurement module 6 to the connection with the electric push rod 3, providing a reference for the rotation angle and ensuring the alignment effect.

[0052] The drilling module 5 includes a drilling motor 501, a drill rod 502 and a drill bit 503. The drill rod 502 is fixedly installed on the output end of the drilling motor 501, and the drill bit 503 is fixedly connected to the bottom end of the drill rod 502. The diameters of the drill rod 502 and the drill bit 503 are comparable, and the end of the drill bit 503 is an inverted cone-shaped contraction transition. A spiral protrusion is provided on the drill bit 503.

[0053] When the drilling module 5 is in operation, the drilling motor 501 drives the drill rod 502 and the drill bit 503 to rotate, and the spiral protrusion provided on the drill bit 503 is used to discharge the soil. The electric push rod 3 simultaneously provides a pushing effect to cooperate with the deepening of the drilling module 5.

[0054] The magnetic measurement module 6 includes an adapter block 601, a probe rod 602 and a probe 603. The top of the adapter block 601 is electrically connected to the magnetic measurement host 8 through a wire. The adapter block 601 mainly provides power to the probe 603 and serves as a transit for data transmission between the probe 603 and the magnetic measurement host 8 to ensure stable data transmission. The probe rod 602 is fixedly installed at the bottom, and the probe 603 is fixedly installed at the end of the probe rod 602.

[0055] When the magnetic measurement module 6 is in operation, the data detected by the probe 603 is transmitted to the magnetic measurement host 8 through the adapter block 601, and then the magnetic measurement host 8 performs analysis and processing.

[0056] The protective member 7 includes a sleeve 701, a cavity 702, a shell 703, a shaft 704, a blade 705, a gear 706, a rack 707, a water outlet 708, a water inlet 709 and a straw 710. The probe rod 602 is fixedly sleeved with a sleeve 701. The sleeve 701 is provided with a cavity 702 enclosed for the probe 603. A shell 703 is fixedly installed on one side of the probe rod 602. A shaft 704 is rotatably installed in the shell 703. The blade 705 is fixedly installed on the shaft 704. The shell 703 is cylindrical, and the blade 705 installed therein It can cover most of the internal space of the shell 703. A gear 706 is fixedly installed on one end of the shaft 704 extending out of the shell 703. A rack 707 cooperating with the gear 706 is fixedly provided on the support module 2. A water outlet 708 is provided on the top of the shell 703, and a water inlet 709 is provided on the bottom. The water outlet 708 and the water inlet 709 are both upright tubular, but are staggered with each other to ensure that the suction effect generated when the blade 705 rotates is more comprehensive. A straw 710 is connected to the water inlet 709, and the end of the straw 710 extends to the probe 603.

[0057] The function of the protective member 7 is carried out synchronously with the propulsion of the magnetic measurement module 6. When the magnetic measurement module 6 penetrates into the borehole, mud enters from the bottom of the sleeve 701. At the same time, the gear 706 moves downward and rotates with the cooperation of the rack 707, so that the shaft 704 drives the blade 705 to rotate, and a vacuum is briefly formed around the blade 705, thereby generating suction at the suction pipe 710, which continuously sucks out the mud entering the sleeve 701, reducing the resistance of the probe 603 to the mud when it is pushed forward, until the sleeve 701 is against the bottom of the hole. Since most of the mud in the sleeve 701 is sucked out, it will not form a covering around the probe 603. The probe 603 can work without being interfered by the mud, and obtain real and effective detection data.

[0058] The proton magnetometer used in the present invention has a different principle from other types of magnetometers. It belongs to a branch of magnetometers with higher precision. Even when measuring weak magnetic objects, such as the Earth's magnetic field, it can still achieve high resolution and accuracy. Therefore, even weak changes in the Earth's magnetic field can be detected. Its working principle is to use the precession phenomenon of hydrogen protons in the magnetic field for measurement. The sensor is filled with hydrogen-containing liquid. Before being forcibly polarized by the instrument, these hydrogen protons are in a disorderly arrangement state. When a polarization signal is artificially added to them, the protons will perform precession motion. After the polarization signal disappears, the precession of the protons will be mainly affected by the external magnetic field and will gradually disappear. By measuring the frequency in the sensor affected by the precession, the magnitude of the external magnetic field can be detected. By continuously repeating this action, continuous measurement can be achieved.
