[0002] In the field of mineral resource exploration, gravity detection technology is widely used to determine the distribution and density characteristics of underground ore bodies. Existing gravity detection equipment, such as the CG-5, CG-6, and cold atom gravimeters, primarily rely on measuring changes in gravitational acceleration to infer density differences in different underground areas.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In order to solve the technical problem that the gravity acceleration measurement technology relied on by existing gravity detection equipment has certain limitations in the detection of deep ore bodies and extremely small gravity changes, and cannot provide stable and accurate data support, the present invention provides a vertical quantum gravity direction deviation prospecting instrument that can realize the detection of vertical gravity direction deviation.

[0031] See also Figures 1-6 , Figure 1 This is a structural diagram of a vertical quantum gravity direction deviation prospecting instrument in one embodiment of the present invention. The vertical quantum gravity direction deviation prospecting instrument includes a suspension assembly 1, a mercury box 2, a lifting drive mechanism 3, an angle detection mechanism 4 and a data processing module 5.

[0032] The suspension assembly 1 includes an outer shell 11 and an inner shell 12. The outer shell 11 defines a sealed vacuum chamber, within which the inner shell 12 is suspended. The sealed vacuum chamber within the outer shell 11 provides a stable environment for the inner shell 12, free from external interference. The inner shell 12 is suspended within this vacuum chamber, ensuring stability and accuracy during measurement.

[0033] The mercury cartridge 2 is built into the inner housing 12 and is used to hold mercury. The primary function of the mercury cartridge 2 is to contain mercury, as its high density and fluidity make it an ideal medium for detecting deviations in the direction of gravity. When the direction of gravity changes slightly, the angle between the mercury level and the inner top surface of the inner housing also changes. This change serves as the basis for subsequent analysis.

[0034] The lifting drive mechanism 3 is connected to the mercury box 2 and is used to drive the mercury box 2 up and down. This mechanism precisely controls the up and down movement of the mercury box 2, enabling measurements at various heights. This step is crucial for obtaining data on the mercury liquid level inclination at different heights. This mechanism is highly sensitive and accurate, capable of capturing even the slightest changes in the liquid level inclination. These changes are converted into electrical signals or other processable data for subsequent analysis.

[0035] The angle detection mechanism 4 is used to detect the angle between the liquid level in the mercury cartridge 2 and the inner top surface of the inner shell. The data processing module 5 receives data from the angle detection mechanism 4. This module uses advanced algorithms and models to determine the magnitude of the vertical gravity deviation based on the difference in the liquid level inclination angle at at least two different heights of the mercury cartridge 2. This determination process may involve comprehensive analysis of multiple measurement data to ensure the accuracy and reliability of the results.

[0036] The data processing module 5 is used to determine the magnitude of the vertical gravity direction deviation based on the difference in the liquid level inclination angle of the mercury box 2 at at least two different heights detected by the angle detection mechanism 4.

[0037] When in use, the device is transported to the area where gravity prospecting is required by a carrying device, and then left to stand for a period of time until the mercury box 2 is completely still. Then, the first inclination angle of the liquid surface in the mercury box 2 is detected by the angle detection mechanism 4. Then, the mercury box 2 is driven to rise or fall to another height by the lifting drive mechanism 3. Then, the device is left to stand for a period of time until the mercury box 2 is completely still. Then, the second inclination angle of the liquid surface in the mercury box 2 is detected by the angle detection mechanism 4. The size of the vertical gravity direction deviation of the current detection position is judged by the difference between the first inclination angle and the second inclination angle. By detecting the vertical gravity direction deviation, the detection of deep ore bodies and extremely small gravity changes can be achieved.

[0038] In one embodiment, see Figure 1 and Figure 2The suspension assembly 1 also includes a suspension rope 13 and a spring 14. One end of the suspension rope 13 is fixed to the inner top surface of the inner shell 12, and the other end of the suspension rope 13 is fixedly connected to one end of the spring 14, and the other end of the spring 14 is fixedly connected to the upper end of the inner shell 12. The combination of the suspension rope and the spring provides additional suspension stability and shock absorption effect for the inner shell. When the external environment produces slight vibrations or interference, the spring can absorb these vibrations and reduce their impact on the inner shell and the mercury box therein. In addition, the suspension rope serves as the main suspension structure, ensuring that the position of the inner shell in the vacuum chamber always remains vertical, so that even if the test is carried out on an inclined ground, it will not affect the accuracy of the test results.

[0039] In one embodiment, see Figure 2-Figure 4 The mercury box 2 is secured to each side with a fixing lug 21, each provided with a screw hole. The lifting mechanism 3 is connected to the mercury box 2 and is used to drive the mercury box 2 up and down. This mechanism precisely controls the up and down movement of the mercury box 2, enabling measurements at various heights. This step is crucial for obtaining data on the mercury liquid level inclination at various heights.

[0040] The lifting drive mechanism 3 includes two screw rods 31 and a rotation drive assembly 32. The two screw rods 31 are rotatably disposed within the inner housing and are respectively threadedly connected to the screw holes of the two fixing ears 21. The rotation drive assembly 32 is connected to the two screw rods 31 and is used to drive the two screw rods 31 to rotate synchronously. The use of two screw rods and a synchronous drive assembly ensures that the two screw rods rotate synchronously, thereby smoothly driving the mercury box up and down. This design improves the smoothness and accuracy of lifting and lowering, avoiding errors caused by asynchrony. At the same time, the screw drive has the characteristics of high precision and high load-bearing capacity, making it suitable for applications requiring precise control.

[0041] In one embodiment, see Figure 2-Figure 4 The rotation drive assembly 32 includes two synchronous wheels 321, a synchronous belt 322, and a rotation drive member 323. The two synchronous wheels 321 are coaxially fixed to the two screw rods 31. The synchronous belt 322 is closed, and the two ends of the synchronous belt 322 are respectively wound around the two synchronous wheels 321. The rotation drive member 323 is connected to one of the screw rods 31 and is used to drive the screw rod 31 to rotate. The cooperation between the synchronous wheels and the synchronous belt achieves the synchronous rotation of the two screw rods.

[0042] In one embodiment, see Figure 2-Figure 4The rotary drive member 323 includes a rotary drive motor 3231, a driving gear 3232, and a driven gear 3233. The housing of the rotary drive motor 3231 is fixed to the inner housing. The driving gear 3232 is fixedly sleeved on the output shaft of the rotary drive motor 3231. The driven gear 3233 is fixedly sleeved on one of the screw rods 31, and the driven gear 3233 is meshed with the driving gear 3232. The rotary drive motor serves as a power source and provides a stable driving force. This design simplifies the transmission structure, improves transmission efficiency, and reduces noise and energy consumption. In addition, by adjusting the speed and direction of the motor, the lifting speed and direction of the mercury box can be conveniently controlled.

[0043] In one embodiment, see Figure 2-Figure 4 The lifting drive mechanism 3 further includes a first bearing 311 , the inner ring of the first bearing 311 is fixedly sleeved on the screw rod 31 , and the outer ring of the first bearing 311 is fixedly connected to the inner bottom surface of the inner shell.

[0044] In one embodiment, see Figure 2-Figure 4 The lifting drive mechanism 3 also includes a second bearing 312. The inner ring of the second bearing 312 is fixedly mounted on the screw 31, and the outer ring of the second bearing 312 is fixedly connected to the inner top surface of the inner housing. The arrangement of the first bearing and the second bearing respectively fixes the position of the screw on the inner bottom and inner top surfaces of the inner housing, ensuring the stability and reliability of the screw during rotation. This design reduces friction and wear between the screw and the inner housing, extending the service life of the equipment. At the same time, the support provided by the bearings also improves the smoothness and accuracy of the lifting.

[0045] The angle detection mechanism 4 is used to detect the angle between the liquid surface in the mercury box 2 and the inner top surface of the inner shell.

[0046] In one embodiment, see Figure 2-Figure 5The angle detection mechanism 4 includes a fixed plate 41, a fixed seat 42, a sphere 43, an adjustment plate 44, three telescopic members 45, and a laser transmitter-receiver 46. The fixed plate 41 is fixed to the inner top surface of the inner shell, the fixed seat 42 is fixed to the fixed plate 41, the sphere 43 is fixed to the fixed seat 42, and the adjustment plate 44 is movably connected to the sphere 43. The fixed end of each telescopic member 45 is fixed to the fixed plate 41, and the movable end of each telescopic member 45 is fixed to a support plate 451, which is configured to abut the lower end surface of the adjustment plate 44. The laser transmitter-receiver 46 is mounted on the adjustment plate 44 and is configured to emit a laser beam downward toward the liquid surface in the mercury box 2. When the laser transmitter-receiver 46 is perpendicular to the liquid surface in the mercury box 2, it can receive the laser beam reflected back from the liquid surface. This design, through the cooperation of the adjustment plate and the telescopic members, achieves precise alignment between the laser transmitter-receiver and the liquid surface in the mercury box. When the laser beam is reflected back from the liquid surface, it indicates that the laser beam is perpendicular to the liquid surface, and the adjustment plate 44 is also perpendicular to the laser beam, making the adjustment plate 44 parallel to the liquid surface. The extension of the three telescopic members 45 can be used to calculate the angle between the adjustment plate 44 and the inner top surface of the inner shell, thereby obtaining the angle between the liquid surface and the inner top surface of the inner shell. The design of the movable connection between the sphere and the adjustment plate allows the adjustment plate to be freely adjusted within a certain range. In addition, laser measurement is characterized by high precision and high sensitivity, making it suitable for applications requiring precise measurement.

[0047] In one embodiment, see Figure 2-Figure 5 The adjustment plate 44 has a spherical hole, and the sphere 43 is partially embedded in the spherical hole. The design of the spherical hole and the partially embedded sphere on the adjustment plate allows the adjustment plate to rotate and tilt around the sphere within a certain range. This design increases the flexibility of the adjustment plate, making it better able to adapt to different angle adjustment requirements.

[0048] In one embodiment, see Figure 2-Figure 5 The telescopic member 45 is an electric telescopic rod. As a telescopic member, the electric telescopic rod has the characteristics of fast response speed and high control accuracy. Preferably, an electric telescopic rod whose extension length can be determined is used. The electric telescopic rod is electrically connected to the data processing module 5 and directly transmits its own length value to the data processing module 5. The data processing module 5 calculates the angle between the adjustment plate 44 and the inner top surface of the inner shell based on the length of each electric telescopic rod, thereby determining the angle between the liquid level and the inner top surface of the inner shell.

[0049] In order to better understand the present invention, the following Figures 1 to 6The technical solution of the present invention is described in detail: when in use, the device is transported to the area where gravity prospecting is required by a carrying device, and then left to stand for a period of time until the mercury box 2 is completely still, and then the first inclination angle of the liquid surface in the mercury box 2 is detected by the angle detection mechanism 4, and then the mercury box 2 is driven to rise or fall to another height by the lifting drive mechanism 3, and then left to stand for a period of time until the mercury box 2 is completely still, and then the second inclination angle of the liquid surface in the mercury box 2 is detected by the angle detection mechanism 4, and the size of the vertical gravity direction deviation of the current detection position is judged by the difference between the first inclination angle and the second inclination angle. By detecting the vertical gravity direction deviation, the detection of deep ore bodies and extremely small gravity changes can be achieved.
