Description

Technical Field

[0001] This invention belongs to the field of geophysical exploration technology, and specifically relates to a high-precision magnetometer probe attitude adjustment frame for geophysical exploration. Background Technology

[0002] The high-precision magnetometer probe attitude adjustment frame for geophysical exploration is a specialized precision device used in geological exploration to accurately adjust the spatial orientation of a magnetometer probe. The entire device is meticulously crafted from non-magnetic materials, eliminating magnetic interference at its source. It is also equipped with a high-precision angle encoder, providing accurate angle data in real time. Furthermore, its unique environmental adaptability design allows it to operate stably in various complex and harsh geological exploration environments, fully meeting the stringent high-precision requirements of magnetic field measurements.

[0003] Currently, the attitude adjustment frames for high-precision magnetometer probes commonly used in geophysical exploration have significant shortcomings in practical field applications. Their designs typically employ a relatively simple structure, relying primarily on a single connecting rod at the bottom as the key support component, while auxiliary structures (such as simple bases and anti-slip pads) may be quite weak. This support method proves insufficiently resilient to complex field environments: in windy weather, the lack of effective wind-resistant stabilization measures (such as reinforced supports and counterweight balancing designs) makes the adjustment frame prone to tipping over due to instability. This could not only damage precision equipment such as high-precision magnetometer probes and delay exploration progress but also pose safety hazards, urgently requiring improvement and optimization. Summary of the Invention

[0004] To address the problems in related technologies, this invention proposes a high-precision magnetometer probe attitude adjustment frame for geophysical exploration, thereby overcoming the aforementioned technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a high-precision magnetometer probe attitude adjustment frame for geophysical exploration, comprising an adjustment frame body. A movable rod is rotatably mounted on the bottom of the adjustment frame body, and the movable rod is slidably connected inside a fixed rod. An insertion rod is fixedly mounted on the bottom of the fixed rod, and a soil insertion rod is slidably connected inside the insertion rod. The soil insertion rod is fixedly mounted on a movable plate, and the movable plate is slidably connected inside the insertion rod via a telescopic rod. A first rod is rotatably mounted on the movable plate, and a second rod is rotatably mounted on the first rod. The second rod is fixedly mounted on a first worm gear, and the first worm gear meshes with a first worm. The first worm is fixedly mounted on a first rotating shaft, and the first rotating shaft is fixed to a second rotating shaft, which is rotatably mounted on the fixed plate. Both ends of the fixed plate are provided with one-way ratchet and pawl mechanisms, which control the rotation of the second rotating shaft and the threaded rod. The threaded rod is threadedly connected to the movable rod. Both one-way ratchet and pawl mechanisms are controlled by a first handle. The second rotating shaft and the threaded rod are both provided with a reverse rotation mechanism, which controls the second rotating shaft and the threaded rod to rotate in opposite directions.

[0006] Furthermore, three of each of the movable rod, fixed rod, and insertion rod are provided, evenly distributed at the bottom of the adjustment frame body to form a triangle for stability. This triangular layout effectively disperses the external forces on the device, greatly enhancing overall stability. The movable rod is rotatably mounted between two connecting blocks, and a damper is provided between the two connecting blocks of the movable rod. The damper can effectively absorb and buffer the vibrations and impacts generated during the rotation of the movable rod, making the adjustment process smoother.

[0007] Furthermore, several insertion rods are provided, allowing for deeper and more stable insertion into the soil, further enhancing the stability of the device. One end of the telescopic rod is fixedly mounted on the inner wall of the insertion rod, and the other end is fixedly mounted on the movable plate. The telescopic rod's extension and retraction precisely moves the movable plate within the insertion rod. One end of the first rod is rotatably mounted on the movable plate, and the other end is rotatably mounted on one end of the second rod. The other end of the second rod is fixedly mounted on the first worm gear, which is rotatably mounted on a fixed shaft. The fixed shaft is fixedly mounted inside the insertion rod. This structure ensures that the coordinated movement of the first and second rods drives the first worm gear to rotate stably.

[0008] Furthermore, the first rotating shaft is rotatably mounted inside the insert rod, ensuring that the first rotating shaft can rotate flexibly within the insert rod. The fixing plate is fixedly mounted inside the fixing rod, providing stable and reliable support for the second rotating shaft and ensuring its stability during rotation.

[0009] Furthermore, the one-way ratchet and pawl mechanism includes a return spring fixedly mounted on the second rotating shaft. The return spring can quickly reset the pawl after it completes a specific action. The end of the return spring away from the second rotating shaft is fixedly mounted on the pawl. The pawl engages with a ratchet, which is fixedly mounted inside a second worm gear. The one-way transmission function is achieved through the cooperation between the pawl and the ratchet. Limit blocks are provided on both sides of the pawl. The limit blocks are fixedly mounted on a disc, which is rotatably mounted on a fixed plate. The limit blocks effectively limit the range of motion of the pawl, preventing excessive deviation and ensuring the normal operation of the one-way ratchet and pawl mechanism.

[0010] Furthermore, the parts and installation methods of the two sets of unidirectional ratchet and pawl mechanisms are identical, ensuring the consistency and stability of transmission in both directions. Both second worm gears mesh with second worms, which are rotatably mounted inside a fixed rod. Each second worm is fixedly mounted with a transmission wheel, and the two transmission wheels are connected by a transmission belt. One of the second worms is fixedly mounted with a first handle, which is rotatably mounted on the fixed rod. By rotating the first handle, the second worm can be rotated, thereby driving the entire transmission system to work collaboratively through the transmission wheel and transmission belt.

[0011] Furthermore, the reversing rotation mechanism includes a first bevel gear fixedly mounted on a second rotating shaft, the first bevel gear meshing with a second bevel gear, the second bevel gear fixedly mounted on a second handle, and the second handle rotatably mounted on a fixed rod. By rotating the second handle, the second bevel gear can be driven to rotate, thereby driving the first bevel gear and the second rotating shaft to rotate in opposite directions. The parts and installation methods of the two sets of reversing rotation mechanisms are identical, ensuring that the reversing rotation functions in both directions are consistent and reliable.

[0012] Furthermore, a rotating disk is rotatably mounted on the top of the main body of the adjustment frame, and a level is fixedly mounted on the rotating disk. The level can display the horizontal status of the main body of the adjustment frame in real time and accurately, providing a direct reference for adjustment. The output end of a micro motor is fixedly mounted on the rotating disk, and the micro motor is fixedly installed inside the main body of the adjustment frame. The micro motor can drive the rotating disk to rotate according to the feedback from the level, assisting the main body of the adjustment frame to quickly reach a horizontal state.

[0013] Furthermore, a first connecting rod is fixedly installed on the top of the rotating disk, a second connecting rod is rotatably installed on the first connecting rod, and a third connecting rod is rotatably installed on the second connecting rod. A control mechanism is provided between the first connecting rod and the second connecting rod, as well as between the second connecting rod and the third connecting rod. The angle between each connecting rod can be flexibly and precisely adjusted through the control mechanism to meet the needs of different survey scenarios.

[0014] Furthermore, the control mechanism includes a third worm gear rotatably mounted on the first connecting rod, the third worm gear meshing with a third worm, the third worm gear being fixedly connected to the second connecting rod, and the third worm being rotatably mounted on the first connecting rod. By rotating the third worm, the third worm gear can be driven to rotate, thereby driving the second connecting rod to rotate, achieving angle adjustment. The parts and installation methods of both sets of control mechanisms are identical. A magnetometer is fixedly mounted above the third connecting rod, and the magnetometer is used for geophysical exploration work to obtain relevant data.

[0015] The present invention has the following beneficial effects: 1. This adjustment frame achieves precise functional division through the "forward / reverse rotation" of the same first handle, eliminating the need for additional switching components: forward rotation of the first handle activates the second rotating shaft, driving multiple sets of insertion rods to extend and penetrate the soil layer via worm gears and rod transmission. Combined with the triangular support structure at the bottom, this quickly secures the device, enhancing adaptability to complex terrain. Reverse rotation of the first handle directly rotates the threaded rod, raising and lowering the moving rod via threaded transmission, thus adjusting the height of the adjustment frame. The same operating component enables switching between "fixed" and "height adjustment" functions, resulting in a low operational threshold and a seamless process. The reset function is handled independently by a dedicated reverse rotation mechanism (second handle + bevel gear transmission), allowing for targeted retraction of insertion rods and reset of moving rods, avoiding functional confusion and significantly improving the efficiency of deployment, adjustment, and storage during field surveys.

[0016] 2. The rotating disk mounted on top of the main body of the adjustment frame forms the first axial adjustment foundation of the three-axis adjustment system. A level fixed on it can accurately detect the horizontal state of the main body of the adjustment frame in real time. A micro motor drives the rotating disk to achieve initial horizontal adjustment. Control mechanisms located between the first and second connecting rods, and between the second and third connecting rods above the rotating disk, constitute the other two axial adjustment parts. By rotating the corresponding third worm gear, the third worm wheel is driven to rotate, thereby achieving flexible adjustment of the angles between the connecting rods. This coordinated adjustment of the three axes can accurately adjust the magnetometer mounted above the third connecting rod to its optimal working posture, meeting the diverse needs of magnetometer posture in different exploration scenarios. This allows the magnetometer to perform geophysical exploration work in an accurate posture, thereby obtaining more accurate and reliable relevant data.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0022] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0023] Please see Figures 1-8 As shown, this invention is a high-precision magnetometer probe attitude adjustment frame for geophysical exploration, comprising an adjustment frame body 1, a movable rod 2 rotatably mounted at the bottom of the adjustment frame body 1, the movable rod 2 being slidably connected inside a fixed rod 3, an insertion rod 4 fixedly mounted at the bottom of the fixed rod 3, a soil insertion rod 5 slidably connected inside the insertion rod 4, the soil insertion rod 5 being fixedly mounted on a movable plate 6, the movable plate 6 being slidably connected inside the insertion rod 4 via a telescopic rod 7, a first rod member 8 rotatably mounted on the movable plate 6, a second rod member 9 rotatably mounted on the first rod member 8, the second rod member 9 being fixedly mounted on a first worm gear 10, the first worm gear 10 engaging a first worm 1. 1. The first worm gear 11 is fixedly mounted on the first rotating shaft 12, the first rotating shaft 12 is fixed on the second rotating shaft 13, the second rotating shaft 13 is rotatably mounted on the fixed plate 14, and both ends of the fixed plate 14 are provided with one-way ratchet and pawl mechanisms. The one-way ratchet and pawl mechanisms are used to control the rotation of the second rotating shaft 13 and the threaded rod 15. The threaded rod 15 is threadedly connected to the moving rod 2. Both one-way ratchet and pawl mechanisms are controlled by the first handle 16. The second rotating shaft 13 and the threaded rod 15 are provided with a reverse rotation mechanism. The reverse rotation mechanism is used to control the second rotating shaft 13 and the threaded rod 15 to rotate in opposite directions.

[0024] The working principle of the high-precision magnetometer probe attitude adjustment frame for geophysical exploration proposed in this invention is as follows: after moving the high-precision magnetometer probe attitude adjustment frame for geophysical exploration to a suitable position, insert the insertion rod 4 at the bottom of the fixing rod 3 into the soil.

[0025] Rotating the first handle 16 in the forward direction controls the one-way ratchet and pawl mechanism at one end of the fixed plate 14. This one-way ratchet and pawl mechanism drives the second rotating shaft 13 to rotate. Since the first rotating shaft 12 is fixed on the second rotating shaft 13, the first rotating shaft 12 rotates accordingly, which in turn drives the first worm gear 11 fixedly installed on the first rotating shaft 12 to rotate. The first worm gear 11 drives the first worm wheel 10 meshing with it to rotate. The first worm wheel 10 drives the second rod 9 fixed on it to rotate. The second rod 9 drives the first rod 8 rotatably installed on it to move. The first rod 8 pushes the moving plate 6 to slide inside the insertion rod 4 through the telescopic rod 7. The moving plate 6 drives the soil insertion rod 5 fixed on it to move to both sides along the inside of the insertion rod 4, so that the soil insertion rod 5 is inserted into the soil, enhancing the stability of the device.

[0026] When the height of the main body 1 of the adjustment frame needs to be adjusted, the first handle 16 is turned forward again. The one-way ratchet and pawl mechanism at the other end of the fixed plate 14 is activated, controlling the rotation of the threaded rod 15. At this time, the second rotating shaft 13 will not rotate, and the state of the insertion rod 4 and the soil insertion rod 5 will not be affected. The threaded rod 15 is threadedly connected to the moving rod 2. The rotation of the threaded rod 15 causes the moving rod 2 to slide inside the fixed rod 3, thereby realizing the height adjustment of the main body 1 of the adjustment frame.

[0027] When the survey work is completed and the insertion rod 5 and the moving rod 2 need to be reset, the reverse rotation mechanism set on the second rotating shaft 13 and the threaded rod 15 is used to control the second rotating shaft 13 to rotate in the opposite direction. This, in turn, drives the moving plate 6 to move in the opposite direction through the first worm 11, the first worm wheel 10, the second rod 9, the first rod 8, and other parts, so that the insertion rod 5 retracts into the insertion rod 4. At the same time, the threaded rod 15 is controlled to rotate in the opposite direction, driving the moving rod 2 to retract into the fixed rod 3, thus completing the reset operation of the device for subsequent handling and reuse.

[0028] In one embodiment, for the aforementioned movable rod 2, three of each—the movable rod 2, the fixed rod 3, and the insertion rod 4—are provided, evenly distributed at the bottom of the adjustment frame body 1 to form a triangular layout. This triangular layout structure greatly enhances the stability of the entire adjustment frame, allowing it to remain stable even in complex terrain and environments. The movable rod 2 is rotatably mounted between two connecting blocks 37. A damper is provided between the two connecting blocks 37 of the movable rod 2. The damper can effectively absorb and buffer the vibration and impact generated during the rotation of the movable rod 2, making the adjustment process smoother and reducing the impact of shaking on the measurement accuracy of the magnetometer.

[0029] In one embodiment, several soil insertion rods 5 are provided. Multiple soil insertion rods 5 can be inserted deeper and more firmly into the soil, further improving the stability of the device and ensuring that the adjustment frame will not easily shake during the exploration process. One end of the telescopic rod 7 is fixedly installed on the inner wall of the insertion rod 4, and the other end is fixedly installed on the movable plate 6. The extension and retraction of the telescopic rod 7 can precisely drive the movable plate 6 to move inside the insertion rod 4, thereby realizing the extension and retraction operation of the soil insertion rod 5. One end of the first rod 8 is rotatably installed on the movable plate 6, and the other end is rotatably installed on one end of the second rod 9. The other end of the second rod 9 is fixedly installed on the first worm gear 10. The first worm gear 10 is rotatably installed on the fixed shaft 17, which is fixedly installed inside the insertion rod 4. This structural design allows the linkage movement of the first rod 8 and the second rod 9 to drive the first worm gear 10 to rotate stably, thereby realizing the orderly operation of the entire transmission system.

[0030] In one embodiment, the first rotating shaft 12 is rotatably mounted inside the insert rod 4, ensuring that the first rotating shaft 12 can rotate flexibly within the insert rod 4, providing a foundation for subsequent transmission. The fixing plate 14 is fixedly mounted inside the fixing rod 3, providing stable and reliable support for the second rotating shaft 13, ensuring the stability of the second rotating shaft 13 during rotation, and avoiding the impact on the performance of the entire adjustment frame due to unstable support.

[0031] In one embodiment, the unidirectional ratchet and pawl mechanism includes a return spring 18 fixedly mounted on the second rotating shaft 13. The return spring 18 can quickly reset the pawl 19 after it completes a specific action, ensuring the normal operation of the unidirectional ratchet and pawl mechanism. The end of the return spring 18 away from the second rotating shaft 13 is fixedly mounted on the pawl 19. The pawl 19 engages with a ratchet 20, which is fixedly mounted inside the second worm gear 21. The unidirectional transmission function is achieved through the cooperation between the pawl 19 and the ratchet 20, ensuring that the second rotating shaft 13 and the threaded rod 15 can only rotate in a specific direction. Limit blocks 38 are provided on both sides of the pawl 19. The limit blocks 38 are fixedly mounted on a disc 23, which is rotatably mounted on a fixed plate 14. The limit blocks 38 effectively limit the range of motion of the pawl 19, preventing excessive deviation and ensuring the stable and reliable operation of the unidirectional ratchet and pawl mechanism.

[0032] In one embodiment, for the aforementioned one-way ratchet and pawl mechanism, the parts and installation methods of the two sets of one-way ratchet and pawl mechanisms are identical, ensuring the consistency and stability of transmission in both directions, so that the adjustment operation of the adjusting frame in both directions can be synchronized and precise. Both second worm gears 21 are engaged with second worms 22, which are rotatably mounted inside the fixed rod 3. Each second worm 22 is fixedly mounted with a transmission wheel 36, and the two transmission wheels 36 are connected by a transmission belt 24. One of the second worms 22 is fixedly mounted with a first handle 16, which is rotatably mounted on the fixed rod 3. By rotating the first handle 16, the second worm 22 can be driven to rotate, thereby driving the entire transmission system to work collaboratively through the transmission wheel 36 and the transmission belt 24, achieving rotational control of the second rotating shaft 13 and the threaded rod 15.

[0033] In one embodiment, the aforementioned reverse rotation mechanism includes a first bevel gear 25 fixedly mounted on a second rotating shaft 13. The first bevel gear 25 meshes with a second bevel gear 26, which is fixedly mounted on a second handle 27. The second handle 27 is rotatably mounted on a fixed rod 3. By rotating the second handle 27, the second bevel gear 26 can be driven to rotate, thereby causing the first bevel gear 25 and the second rotating shaft 13 to rotate in opposite directions, thus realizing the reverse adjustment function of the adjustment frame. The parts and installation methods of the two sets of reverse rotation mechanisms are identical, ensuring that the reverse rotation functions in both directions are consistent and reliable, meeting different adjustment needs.

[0034] The working principle of the high-precision magnetometer probe attitude adjustment frame for geophysical exploration proposed in this invention is as follows: when the high-precision magnetometer probe attitude adjustment frame for geophysical exploration is working, three structures composed of a moving rod 2, a fixed rod 3 and an insert rod 4 are evenly distributed at the bottom of the main body 1 of the adjustment frame, forming a triangular layout, which greatly enhances the stability of the adjustment frame and enables it to remain stable in complex terrain and environment.

[0035] The movable rod 2 is rotatably mounted between two connecting blocks 37, and a damper is provided between the two connecting blocks 37 to effectively absorb and buffer the vibration and impact generated when the movable rod 2 rotates, making the adjustment process smoother and reducing the impact on the measurement accuracy of the magnetometer.

[0036] After moving the adjusting frame to the appropriate position, insert the insertion rod 4 into the soil. Several insertion rods 5 are provided, with one end of the telescopic rod 7 fixed to the inner wall of the insertion rod 4 and the other end fixed to the moving plate 6. Rotating the first handle 16 causes the fixed second worm gear 22 to rotate. This second worm gear 22, through the transmission wheel 36 and transmission belt 24, drives another second worm gear 22 to rotate. The two second worm gears 22 respectively drive the meshing second worm wheel 21 to rotate. The ratchet 20 inside the second worm wheel 21 rotates accordingly. The pawl 19, under the action of the return spring 18, engages with the ratchet 20 to achieve unidirectional transmission, driving the second rotating shaft 13 to rotate. The second rotating shaft 13 drives the first rotating shaft 12 to rotate. The first worm gear 11 on the first rotating shaft 12 drives the first worm wheel 10 to rotate on the fixed shaft 17. The first worm wheel 10 drives the second rod 9 to rotate. The second rod 9 drives the first rod 8 to move. The first rod 8 pushes the moving plate 6 to slide inside the insertion rod 4 through the telescopic rod 7, so that the soil insertion rod 5 extends out of the insertion rod 4 and penetrates into the soil, further improving the stability of the device.

[0037] When it is necessary to adjust the height of the main body 1 of the adjustment frame, continue to rotate the first handle 16. Through the above transmission process, the threaded rod 15 rotates. Since the threaded rod 15 is threadedly connected to the moving rod 2, the moving rod 2 slides in the fixed rod 3 to achieve height adjustment.

[0038] To adjust the three movable rods 2 to keep the main body 1 of the adjustment frame horizontal, turn the first handle 16 to make the three movable rods 2 slide in the corresponding fixed rods 3 through the transmission system. According to the feedback from the level and other detection devices, the main body 1 of the adjustment frame is adjusted to a horizontal state.

[0039] When the survey work is completed and resetting is required, turn the second handle 27. The second handle 27 drives the second bevel gear 26 to rotate, and the second bevel gear 26 drives the first bevel gear 25, which meshes with it, to rotate. This, in turn, drives the second rotating shaft 13 to rotate in the opposite direction. Through the transmission system, the soil insertion rod 5 retracts into the insertion rod 4. At the same time, turn the first handle 16 in the opposite direction to make the threaded rod 15 rotate in the opposite direction, which drives the moving rod 2 to retract into the fixed rod 3, thus completing the device resetting for subsequent handling and reuse.

[0040] In one embodiment, for the aforementioned adjusting frame body 1, a rotating disk 28 is rotatably mounted on the top of the adjusting frame body 1. A level 29 is fixedly mounted on the rotating disk 28. The level 29 can display the horizontal status of the adjusting frame body 1 in real time and accurately, providing an intuitive reference for adjustment operations and facilitating operators to quickly determine whether the adjusting frame is in a horizontal position. The rotating disk 28 is fixedly mounted with the output end of a micro motor, which is fixedly installed inside the adjusting frame body 1. The micro motor can automatically drive the rotating disk 28 to rotate based on the feedback from the level 29, assisting the adjusting frame body 1 to quickly reach a horizontal state and improving adjustment efficiency and accuracy.

[0041] In one embodiment, for the aforementioned rotating disk 28, a first connecting rod 30 is fixedly installed on the top of the rotating disk 28, a second connecting rod 31 is rotatably installed on the first connecting rod 30, and a third connecting rod 32 is rotatably installed on the second connecting rod 31. A control mechanism is provided between the first connecting rod 30 and the second connecting rod 31, as well as between the second connecting rod 31 and the third connecting rod 32. Through the control mechanism, the angle between each connecting rod can be flexibly and accurately adjusted, so that the magnetometer probe can be adjusted to the optimal working posture to meet the needs of different exploration scenarios.

[0042] In one embodiment, the control mechanism includes a third worm gear 33 rotatably mounted on the first connecting rod 30. The third worm gear 33 meshes with a third worm 34, which is fixedly connected to the second connecting rod 31. The third worm 34 is rotatably mounted on the first connecting rod 30. Rotating the third worm 34 drives the third worm gear 33 to rotate, which in turn drives the second connecting rod 31 to rotate, thus achieving angle adjustment. The parts and installation methods of both control mechanisms are identical, ensuring consistent and reliable angle adjustment functions in both directions. A magnetometer 35 is fixedly mounted above the third connecting rod 32. The magnetometer 35 is used for geophysical exploration to obtain relevant data. The stability of its installation position and the accuracy of its angle adjustment directly affect the accuracy of the exploration results.

[0043] The working principle of the high-precision magnetometer probe attitude adjustment frame for geophysical exploration proposed in this invention is as follows: after the main body 1 of the adjustment frame is placed at the exploration position, the rotating disk 28 mounted on its top plays a key adjustment role. A level 29 fixedly installed on the rotating disk 28 can detect the horizontal state of the main body 1 of the adjustment frame in real time and accurately. A micro motor is used to drive the rotating disk 28 to rotate, forming multi-directional adjustment.

[0044] The rotating disk 28 and the components above it constitute a three-axis adjustment system for precise, all-around adjustment of the magnetometer 35's attitude. The rotating disk 28 serves as the foundation for the first axial adjustment of the three-axis system; its rotation enables initial horizontal adjustment.

[0045] A first connecting rod 30 is fixedly installed on the top of the rotating disk 28. Control mechanisms are respectively provided between the first connecting rod 30 and the second connecting rod 31, and between the second connecting rod 31 and the third connecting rod 32. These two control mechanisms constitute the other two axial adjustment parts of the three-axis adjustment.

[0046] Each control mechanism consists of a third worm gear 33 rotatably mounted on a first connecting rod 30 (or a second connecting rod 31) and a third worm 34 meshing with the third worm gear 33. The third worm gear 33 is fixedly connected to the second connecting rod 31 (or a third connecting rod 32), and the third worm 34 is rotatably mounted on the first connecting rod 30 (or the second connecting rod 31).

[0047] When it is necessary to adjust the angle between the first connecting rod 30 and the second connecting rod 31, the third worm gear 34 corresponding to the control mechanism is rotated. The third worm gear 34 drives the third worm wheel 33 to rotate, which in turn drives the second connecting rod 31 to rotate around the first connecting rod 30, thus achieving the axial angle adjustment. Similarly, when adjusting the angle between the second connecting rod 31 and the third connecting rod 32, the third worm gear 34 of the other control mechanism is rotated, driving the third worm wheel 33 to rotate, causing the third connecting rod 32 to rotate around the second connecting rod 31, thus completing the axial angle adjustment.

[0048] Through the coordinated adjustment of these three axes (the horizontal rotation of the rotating disk 28, the rotation of the first connecting rod 30 and the second connecting rod 31, and the rotation of the second connecting rod 31 and the third connecting rod 32), the magnetometer 35 mounted above the third connecting rod 32 can be flexibly and precisely adjusted to its optimal working posture, meeting the diverse needs of the magnetometer 35's posture in different exploration scenarios. When the magnetometer 35 is in an accurate posture, it can obtain more accurate and reliable relevant data during geophysical exploration.
