DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0018] 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.

[0019] See also Figure 1-Figure 6 , Figure 1 This is a schematic diagram of the structure 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.

[0020] The suspension assembly 1 includes an outer shell 11 and an inner shell 12. The outer shell 11 has a sealed vacuum chamber, and the inner shell 12 is suspended in the vacuum chamber. The outer shell 11 has a sealed vacuum chamber inside, which provides a stable environment for the inner shell 12 that is not disturbed by the outside world. The inner shell 12 is suspended in the vacuum chamber, ensuring its stability and accuracy during the measurement process.

[0021] The mercury box 2 is built into the inner shell 12, and is used to contain mercury. The main function of the mercury box 2 is to contain mercury, because the high density and fluidity of mercury make it an ideal medium for detecting the deviation of the gravity direction. When the gravity direction changes slightly, the angle between the mercury liquid surface and the inner top surface of the inner shell will also change, and this change will serve as the basis for subsequent analysis.

[0022] The lifting drive mechanism 3 is connected to the mercury box 2 and is used to drive the mercury box 2 to move up and down. This mechanism can accurately control the up and down movement of the mercury box 2 so that it can be measured at different heights. This step is crucial for obtaining data on the inclination angle of the mercury liquid surface at different heights. This mechanism has a high degree of sensitivity and accuracy and can capture slight changes in the inclination angle of the liquid surface. These changes will be converted into electrical signals or other processable data forms for subsequent analysis.

[0023] 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. The data processing module 5 receives data from the angle detection mechanism 4. The module uses advanced algorithms and models to determine the magnitude of the vertical gravity direction deviation based on the difference in the liquid surface inclination angle of the mercury box 2 at at least two different heights. This judgment process may involve a comprehensive analysis of multiple measurement data to ensure the accuracy and reliability of the results.

[0024] The data processing module 5 is used to determine the magnitude of the vertical gravity direction deviation according to the difference in the liquid surface inclination angle of the mercury box 2 at at least two different heights detected by the angle detection mechanism 4.

[0025] When in use, the device is transported to an 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 realized.

[0026] In one embodiment, see Figure 1 and Figure 2 The 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, 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, as the main suspension structure, ensures that the position of the inner shell in the vacuum chamber always remains vertical, so that the accuracy of the detection result will not be affected even if the detection is carried out on an inclined ground.

[0027] In one embodiment, see Figure 2-Figure 4 , a fixing ear 21 is fixed on both sides of the mercury box 2, and a screw hole is provided on the fixing ear 21. The lifting drive mechanism 3 is connected to the mercury box 2 and is used to drive the mercury box 2 to move up and down. This mechanism can accurately control the up and down movement of the mercury box 2 so that it can be measured at different heights. This step is crucial for obtaining data on the inclination of the mercury liquid surface at different heights.

[0028] The lifting drive mechanism 3 includes two screw rods 31 and a rotation drive assembly 32. The two screw rods 31 are both rotatably arranged in the inner shell. The two screw rods 31 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 can ensure that the two screw rods rotate synchronously, thereby smoothly driving the mercury box to move up and down. This design improves the stability and accuracy of lifting and lowering, and avoids errors caused by asynchronism. At the same time, the screw drive has the characteristics of high precision and high load-bearing capacity, and is suitable for occasions requiring precise control.

[0029] 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 synchronous rotation of the two screw rods is achieved through the cooperation of the synchronous wheels and the synchronous belt.

[0030] In one embodiment, see Figure 2-Figure 4 The rotating driving member 323 includes a rotating driving motor 3231, a driving gear 3232 and a driven gear 3233. The housing of the rotating driving motor 3231 is fixed to the inner housing. The driving gear 3232 is fixedly sleeved on the output shaft of the rotating driving motor 3231. The driven gear 3233 is fixedly sleeved on one of the screw rods 31. The driven gear 3233 is meshed with the driving gear 3232. The rotating driving motor serves as a power source and provides a stable driving force. This design simplifies the transmission structure, improves the 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.

[0031] In one embodiment, see Figure 2-Figure 4The lifting drive mechanism 3 further includes a first bearing 311, an inner ring of the first bearing 311 is fixedly sleeved on the screw rod 31, and an outer ring of the first bearing 311 is fixedly connected to the inner bottom surface of the inner shell.

[0032] 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 sleeved on the screw rod 31, and the outer ring of the second bearing 312 is fixedly connected to the inner top surface of the inner shell. The arrangement of the first bearing and the second bearing respectively fixes the position of the screw rod on the inner bottom surface and the inner top surface of the inner shell, ensuring the stability and reliability of the screw rod during rotation. This design reduces the friction and wear between the screw rod and the inner shell, and prolongs the service life of the equipment. At the same time, the supporting role of the bearing also improves the stability and accuracy of lifting.

[0033] 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.

[0034] In one embodiment, see Figure 2-Figure 5 The 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 integrated machine 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, 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 with a support plate 451, and the support plate 451 is used to abut against the lower end surface of the adjustment plate 44. The laser transmitter-receiver integrated machine 46 is installed on the adjustment plate 44 and is used to emit a laser beam downward to the liquid surface in the mercury box 2, and can receive the laser beam reflected back from the liquid surface when the laser transmitter-receiver integrated machine 46 is perpendicular to the liquid surface in the mercury box 2. This design realizes the precise alignment between the laser transmitter-receiver integrated machine and the liquid surface in the mercury box through the cooperation of the adjustment plate and the telescopic member. When the laser beam reflected from the liquid surface is received, it indicates that the laser beam is perpendicular to the liquid surface, and the adjustment plate 44 is also perpendicular to the laser beam, so that the adjustment plate 44 is parallel to the liquid surface. The angle between the adjustment plate 44 and the inner top surface of the inner shell can be calculated by the elongation of the three telescopic parts 45, 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 enables the adjustment plate to freely adjust the angle within a certain range. In addition, laser measurement has the characteristics of high precision and high sensitivity, and is suitable for occasions requiring precise measurement.

[0035] In one embodiment, see Figure 2-Figure 5The adjustment plate 44 is provided with a spherical hole, and the sphere 43 is partially built into the spherical hole. The design of the spherical hole provided on the adjustment plate and the partially built-in sphere enables the adjustment plate to rotate and tilt around the sphere within a certain range. This design increases the flexibility of the adjustment plate, enabling it to better adapt to the adjustment requirements of different angles.

[0036] 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, and preferably uses an electric telescopic rod that can obtain the extension length of the electric telescopic rod. The electric telescopic rod is electrically connected to the data processing module 5, and directly sends 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 according to the length of each electric telescopic rod, thereby obtaining the angle between the liquid surface and the inner top surface of the inner shell.

[0037] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the present invention is described in detail: when in use, the device is transported to an 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 realized.
