Description

Technical Field

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

[0002] Mineral exploration is an important part of geological survey. At present, magnetic exploration has been widely used in it. According to the characteristics that useful minerals in ores have magnetism or there are magnetic minerals symbiotic with them, direct prospecting is carried out, or according to the characteristics that ore bodies are related to certain magnetic geological body structures in terms of genesis or space, indirect prospecting is carried out. These ores include iron ore, lead-zinc ore, copper ore, etc. In cooperation with mine area exploration, the burial depth, occurrence and continuity of ore bodies are studied, the shape and size of ore bodies are studied, the scale of ore deposits is estimated, engineering exploration, environmental exploration, hydrology, petroleum, natural gas exploration are carried out, and problems such as geological structures and tectonics related to oil and gas are studied.

[0003] During the process of detecting minerals by applying a proton magnetometer, since most minerals are located deep underground, drilling needs to be combined, that is, the probe of the proton magnetometer is lowered into the borehole to measure the magnetic field of the surrounding rock formation of the borehole wall. However, in the existing detection methods, it is difficult to effectively combine the drilling work and the magnetic measurement work, and separate equipment needs to be used independently, which is rather troublesome. In addition, there will be slurry leaked from the surrounding soil layer left in the borehole. On the one hand, the presence of the slurry will generate a large viscous resistance, affecting the advancement of the probe. On the other hand, magnetite, hematite and other minerals (from the formation or additives) are mixed into the drilling slurry, and these particles will generate an additional magnetic field, interfering with the measurement of the true geomagnetic field by the probe. At present, the above problems have not been effectively solved in the application of magnetic exploration in geology. Summary of the Invention

[0004] The present invention provides an exploration device for geological survey, which solves the technical problems in the related art that it is difficult to effectively combine the drilling work and the magnetic measurement work and it is difficult to avoid the interference of the slurry.

An inclined strut is fixedly arranged on the slider. A hollow threaded sleeve is arranged at the end of the inclined strut. The threaded sleeve is threadedly connected with a second stud.

[0007] As a further solution of the present invention: A chute is opened in the bracket. The slider is slidably matched with the chute. A clamping plate is fixedly arranged on the slider. The clamping plate is in a semi-surrounding shape with respect to the side of the bracket. A first stud is threadedly connected in the clamping plate. After the first stud is screwed in, it abuts against the bracket.

[0008] As a further solution of the present invention: The support module further includes a support plate, and the support plate alternately fits with the drilling module and the magnetic measurement module.

[0009] As a further solution of the present invention: The conversion module includes a conversion motor, a connecting plate, end blocks, clamping columns, connectors, an opening clamping plate, a chuck and a fastening screw. A conversion motor is fixedly arranged on the base. End blocks are symmetrically fixedly arranged on the output end of the conversion motor. Clamping columns are fixedly installed on the end blocks. Opening clamping plates for cooperating with the clamping columns are fixedly arranged on both the drilling module and the magnetic measurement module. A chuck is fixedly arranged on the output end of the electric push rod. A fastening screw is threadedly connected in the chuck. Connectors for cooperating with the fastening screw are fixedly arranged on the tops of both the drilling module and the magnetic measurement module.

[0010] As a further solution of the present invention: The conversion module further includes a pointer and a code disk. A pointer is fixedly arranged on the top of the end block. The code disk is fixedly arranged on the base. The code disk is circular and marked with readings at intervals of 90 degrees.

[0011] As a further solution of the present invention: The drilling module includes a drilling motor, a drill rod and a drill bit. A drill rod is fixedly installed on the output end of the drilling motor. The bottom end of the drill rod is fixedly connected with a drill bit. Spiral protrusions are arranged on the drill bit.

[0012] As a further solution of the present invention: The magnetic measurement module includes an adapter block, a probe rod and a probe head. The top of the adapter block is electrically connected with the magnetic measurement host through a wire. A probe rod is fixedly arranged at the bottom. A probe head is fixedly arranged at the end of the probe rod.

[0013] As a further solution of the present invention: The protective member includes a sleeve, a cavity, a housing, a shaft rod, blades, a gear, a rack, a water outlet, a water inlet and a suction pipe. The sleeve is fixedly sleeved outside the probe rod. A cavity for enclosing the probe head is arranged in the sleeve. A housing is fixedly installed on one side of the probe rod. A shaft rod is rotatably installed in the housing. Blades are fixedly installed on the shaft rod. A gear is fixedly installed at one end of the shaft rod extending out of the housing. A rack cooperating with the gear is fixedly arranged on the support module. A water outlet is arranged at the top of the housing, and a water inlet is arranged at the bottom. A suction pipe is connected to the water inlet, and the end of the suction pipe extends to the probe head.

[0014] The beneficial effects of the present invention are as follows: The present invention constructs an operation mode of "ground magnetic measurement positioning anomaly" - "drilling verification" - "fine magnetic measurement detection in the hole". This exploration mode that organically combines the horizontal and vertical directions can effectively combine the drilling work and the magnetic measurement work by means of the conversion module, forming a magnetic measurement mode of preliminary and then precise positioning, effectively avoiding blind drilling, reducing the exploration cost, and significantly improving the overall efficiency of the magnetic measurement work.

[0015] The function of the protective member in the present invention is carried out synchronously with the advancing action of the magnetic measurement module. During the process of the magnetic measurement module penetrating into the drill hole, the mud enters from the bottom of the sleeve. At the same time, the gear moves downward and rotates under the cooperation of the rack, so that the shaft rod drives the blades to rotate, briefly forming a vacuum around the blades, thereby generating suction at the suction pipe, continuously sucking out the mud entering the sleeve, reducing the resistance of the mud when the probe head advances. Until the sleeve abuts against the bottom of the hole, most of the mud in the sleeve is sucked out and will not form a coating around the probe head. The probe head can work in a state free from the interference of the mud and obtain real and effective detection data.

[0016] The proton magnetometer used in the present invention has a different principle from other types of magnetometers. It belongs to a highly accurate branch among many magnetometers. Even for the measurement of weak magnetic substances, such as the earth's magnetic field, it can still obtain high resolution and accuracy. Therefore, even for the weak changes in the earth's magnetic field, it can be detected. Its working principle is to measure by using the precession phenomenon of hydrogen protons in the magnetic field. In the sensor, it is filled with hydrogen-containing liquid. These hydrogen protons are in a disordered arrangement state before being forced to be polarized by the instrument. When an artificial polarization signal is applied to it, the protons will perform precession motion. After the polarization signal disappears, the precession of the protons will gradually disappear mainly under the influence of the external magnetic field. By measuring the frequency in the sensor affected by the precession, the magnitude of the external magnetic field can be detected. By continuously cycling this action, continuous measurement can be carried out. Description of the Drawings

Magnetic measurement host Specific implementation manners

[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0020] The present invention discloses a prospecting device for geological survey, such as Figure 1 - Figure 10 shown in the figure, which 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 component 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 pushing direction is vertical. On the one hand, it provides a cooperative lifting effect when the drilling module 5 drills, and on the other hand, it is used to pull the magnetic measurement module 6 into or out of the drill hole. The conversion module 4 is fixedly arranged on the support module 2, and the conversion module 4 is cooperatively arranged with the drilling module 5 and the magnetic measurement module 6, driving the drilling module 5 and the magnetic measurement module 6 to alternately fasten to the output end of the electric push rod 3. Referring to the form set in Figure 2 the figure, that is, the position of the electric push rod 3 is fixed, and the drilling module 5 and the magnetic measurement module 6 are in a circular rotating plane where the positions can be switched; During mineral prospecting, the magnetic measurement module 6 moves with the trolley 1 on the ground for magnetic measurement to find data anomaly points. At the data anomaly points, a drill hole is opened through the drilling module 5, and then the magnetic measurement module 6 is switched to enter the drill hole for vertical magnetic measurement. A protective component 7 is cooperatively arranged on the magnetic measurement module 6, and the mud in the drill hole is synchronously sucked when the magnetic measurement module 6 moves downwards. A magnetic measurement host 8 electrically connected to the magnetic measurement module 6 is fixedly arranged on the trolley 1. Correspondingly, the magnetic measurement host 8 writes a parameter warning program, that is, a certain parameter range is preset, and when the range is exceeded, an alarm is automatically triggered and used in conjunction with a flash lamp or a buzzer. When finding data anomaly points during the ground magnetic measurement process, the parameter warning program is triggered, and the flash lamp or the buzzer works, which can effectively remind the operator to mark the corresponding points.

[0021] In specific implementation, through the above settings of the present invention, an operator can construct an operation mode of "ground magnetic measurement positioning anomaly" - "drilling verification" - "fine magnetic measurement in the hole", that is, first divide the area to be surveyed into several points at equal intervals, and then without enabling the drilling module 5, only use the cart 1 to carry the magnetic measurement module 6 to preliminarily survey at each point horizontally. When a point with abnormal data is located, use the drilling module 5 to drill a hole at that place, and then switch the magnetic measurement module 6 to be docked 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 hole for fine magnetic measurement vertically.

[0022] This exploration method that organically combines horizontal and vertical directions can effectively combine drilling work and magnetic measurement work by using the function of the conversion module 4, forming a magnetic measurement method of preliminary and then precise positioning, effectively avoiding blind drilling, reducing exploration costs, and significantly improving the overall efficiency of magnetic measurement work.

[0023] The support module 2 includes a base 201, a bracket 202, a top plate 203, a through hole 204, a slider 205, a diagonal brace 206, a threaded sleeve 207 and a second stud 208. A base 201 is fixedly arranged on one side of the cart 1, and the base 201 is slightly higher than the plane where the wheels of the cart 1 are located. Bracket 202s are vertically fixed at the four corners of the base 201. The bracket 202 is in an L shape, including a horizontal part and a vertical part, and its horizontal part is arranged along the diagonal of the base 201. A top plate 203 is fixedly arranged at the center surrounded by the tops of the four groups of bracket 202s. The electric push rod 3 is inserted and fixed on the top plate 203. A through hole 204 that is in pushing cooperation with the electric push rod 3 is opened at the center of the base 201. 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 part 7 to ensure that it can pass through smoothly. A slider 205 is arranged on the bracket 202. A diagonal brace 206 is fixedly arranged on the slider 205. A hollow threaded sleeve 207 is arranged at the end of the diagonal brace 206. The threaded sleeve 207 is threadedly connected with the second stud 208. The diagonal brace 206 is inclined at an acute angle compared with the bracket 202, and the second stud 208 is also inclined at an acute angle compared with the diagonal brace 206, and the contact end of the diagonal brace 206 with the ground is made flat. In this way, compared with ordinary support structures, an additional support point is obtained, making it more stable.

[0024] The support module 2 provides a stable support for the electric push rod 3 during drilling work and precise magnetic measurement. When drilling is required, expand the diagonal brace 206 towards the four corners of the base 201 as Figure 3 shown, and then screw in the second stud 208 to press it into the soil to form a stable four-corner support structure.

[0025] A chute 2021 is provided in the bracket 202. The slider 205 is slidably engaged with the chute 2021. The thickness of the slider 205 is slightly greater than that of the chute 2021. A clamping plate 2051 is fixedly provided on the slider 205. The clamping plate 2051 is semi-surrounding the side of the bracket 202, without affecting the sliding of the slider 205 relative to the chute 2021. A first stud 2052 is threadedly connected in the clamping plate 2051. After the first stud 2052 is tightened, it abuts against the bracket 202.

[0026] By utilizing the sliding fit between the slider 205 and the chute 2021, the diagonal brace 206 obtains an adjustable property. When there is a drop on the ground surface, the slider 205 can be first slid to adjust the orientation angle of the diagonal brace 206, and then the diagonal brace 206 can be locked by screwing in the first stud 2052, and then the bottom of the diagonal brace 206 can be fastened as described above.

[0027] The support module 2 further includes a support plate 209. As Figure 2 shown, the support plate 209 is fan-shaped, and the radian of the fan is matched with the circular trajectory formed when the drilling module 5 and the magnetic measurement module 6 rotate. Thus, while providing a sufficient bearing surface for the support plate 209, the material is minimized as much as possible. It is suspended and fixed above the base 201 by several columns. The support plate 209 alternately fits with the drilling module 5 and the magnetic measurement module 6.

[0028] When the drilling module 5 and the magnetic measurement module 6 alternately dock with the electric push rod 3, the support plate 209 provides a temporary support function that does not affect the rotational switching for the module that is not docked with the electric push rod 3, which cooperates with the function that the conversion module 4 needs to slightly deflect before the electric push rod 3 advances to disengage the clamping post 404 from the opening clamping plate 406.

[0029] The conversion module 4 includes a conversion motor 401, a connecting plate 402, end blocks 403, clamping posts 404, connectors 405, opening clamping plates 406, chucks 407 and fastening screws 408. The conversion motor 401 is fixedly provided on the base 201. End blocks 403 are symmetrically fixedly provided on the output end of the conversion motor 401. Clamping posts 404 are fixedly installed on the end blocks 403. The clamping posts 404 on the two end blocks 403 face in opposite directions. Opening clamping plates 406 that cooperate with the clamping posts 404 are fixedly provided on both the drilling module 5 and the magnetic measurement module 6. A chuck 407 is fixedly provided on the output end of the electric push rod 3. A fastening screw 408 is threadedly connected in the chuck 407. Connectors 405 that cooperate with the fastening screw 408 are fixedly provided on the tops of both the drilling module 5 and the magnetic measurement module 6.

[0030] When the conversion module 4 is specifically implemented, the conversion motor 401 drives the connecting plate 402 to rotate, and the cooperation between the clamping post 404 and the opening clamping plate 406 is used to push the drilling module 5 and the magnetic measurement module 6, so that they are alternately aligned with the acting 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 abuts against the inner wall of the chuck 407 for fixation. When it needs to be disassembled, it is the same.

[0031] The conversion module 4 further includes a pointer 409 and a code disk 410. The pointer 409 floats above the code disk 410. The pointer 409 is fixedly arranged at the top of the end block 403, and the code disk 410 is fixedly arranged on the base 201. The code disk 410 is circular, and readings are marked at intervals of 90 degrees, which are 0 degrees, 90 degrees, 180 degrees, and 270 degrees respectively.

[0032] The cooperation between the pointer 409 and the code disk 410 is used for the above-mentioned function of switching the docking of the drilling module 5 and the magnetic measurement module 6 with the electric push rod 3, providing a reference for the rotation angle, and ensuring the alignment effect.

[0033] The drilling module 5 includes a drilling motor 501, a drill pipe 502, and a drill bit 503. The drill pipe 502 is fixedly installed on the output end of the drilling motor 501, and the bottom end of the drill pipe 502 is fixedly connected with the drill bit 503. The diameters of the drill pipe 502 and the drill bit 503 are equivalent, and the end of the drill bit 503 is tapered and contracted in a transition manner. The drill bit 503 is provided with spiral protrusions.

[0034] When the drilling module 5 functions, the drilling motor 501 drives the drill pipe 502 and the drill bit 503 to rotate, and the spiral protrusions provided on the drill bit 503 are used to discharge the soil. The electric push rod 3 synchronously provides a pushing effect to cooperate with the deepening of the drilling module 5.

[0035] 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 transfer for data transmission between the probe 603 and the magnetic measurement host 8 to ensure the stability of data transmission. The probe rod 602 is fixedly arranged at the bottom, and the probe 603 is fixedly arranged at the end of the probe rod 602.

[0036] When the magnetic measurement module 6 functions, 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.

[0037] 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, and a cavity 702 enclosed by the probe 603 is provided in the sleeve 701. A shell 703 is fixedly installed on one side of the probe rod 602, and 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 rod 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.

[0038] 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 tube 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 cover around the probe 603. The probe 603 can work without being disturbed by the mud, and obtain real and effective detection data.

[0039] The proton magnetometer used in the present invention has a different principle from other types of magnetometers. It belongs to a branch with higher precision among many magnetometers. Even when measuring weaker magnetic objects, such as the earth's magnetic field, it can still achieve higher resolution and accuracy, so even slight 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 an irregular arrangement state. When a polarization signal is added to them artificially, 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 size of the external magnetic field can be detected. By continuously cycling this action, continuous measurement can be achieved.

[0040] Main features: Gradient measurement (horizontal or vertical) can be carried out. It has an RS-232C computer interface. The case is made of hard aluminum alloy with a special waterproof connector, suitable for harsh environments, shockproof and rainproof. High resolution, with a resolution of 0.1 nT, meeting the requirements of the "Ground High-precision Magnetic Survey Work Specification" issued by the former Ministry of Geology and Mineral Resources. The dedicated software can output data in a common format to professional geological software for drawing isograms, cross-sections and other relevant materials. Large memory, capable of storing 10,000 measuring points. It can be used for field operations and also as a base station measurement. Lightweight and portable, the whole system uses a backpack and straps, and one person can complete all measurement tasks. The backlit 2x16-bit LCD liquid crystal display has a fast response speed, low energy consumption, the backlight can be switched on and off, no radiation, no flicker, and long-term use is beneficial to health. The signal quality is monitored in real time, and a decrease in signal quality can be detected in time for remedial measures. It can be automatically tuned in the full range or manually tuned. In addition to the main battery as the power supply, the secondary battery is used to save settings and measurement results, and the data can be saved for 10 years.

[0041] The embodiments of the present invention have been described above, but these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make more equivalent embodiments in various forms, all of which fall within the protection scope of this embodiment.
