The structure is simple and reasonable; a digital intelligent control drilling geological parameter measuring device is realized, which is convenient to operate, quickly measures drilling geological parameters, reduces labor intensity, and improves work efficiency; the MSP430F5529 single-chip microcomputer uses a segmented PID control algorithm to control the DC servo motor, and the lifting and lowering sensors are accurate, ensuring the smooth measurement of drilling geological parameters and improving the accuracy of measurement data.

[0004] However, although the above technical solution can effectively measure the hole depth, it cannot accurately obtain the inclination angle of the borehole. At the same time, it may be necessary to sample underground minerals during the descent process. The current common technical means is to simply add a retractable sampler, but the sampling effect is poor and targeted sampling cannot be performed. Based on the above problems, the present application proposes a drilling measurement equipment and measurement method for mineral geology. Summary of the invention

On the other hand, it can be used in conjunction with the sampling structure to shoot the sampling object of the sampling structure and which specific sampling structure of the sampling object is, so as to ensure that the sample, sample position, and sample collection structure correspond to each other after the sample is taken out to prevent confusion. A plurality of flexible material collection components, rigid material collection components, and liquid material collection components are installed in a circular array in the rotating panel, and the flexible material collection components, rigid material collection components, and liquid material collection components are arranged alternately.

The colored light bar is turned on when sampling, and the other colored light bars remain turned off, so that the sampling position can be roughly marked, and the sampling cylinders can be distinguished by setting the color and number of the colored light bar.

[0012] Preferably, the inner wall of the sampling tube opening of the rigid material collection assembly is provided with a material guiding spiral groove, and the sampling tube can grind and crush the rock when it rotates, and the crushed rock material can enter the sampling tube through the material guiding spiral groove to realize sampling.

[0013] Preferably, the sampling cylinder of the liquid material collection assembly is filled with an adsorption block for liquid adsorption.

[0014] Preferably, the outward push drive component consists of an electric push rod fixed in the measurement and control base, a second motor connected to the telescopic end of the electric push rod, and a plug-in rod fixed on the output shaft of the second motor. The plug-in rod can be inserted into the plug-in slot of the sampling tube to form a connection structure that cannot rotate relative to each other. The second motor is controlled to extend by the electric push rod so that the plug-in rod is inserted into the sampling tube. The sampling tube can be pushed out by continuously extending the electric push rod so that it can contact the sampling position for sampling. If rigid materials need to be collected, the second motor can be controlled to turn on at the same time.

[0015] Preferably, the forward detection measurement and cleaning mechanism includes a rotating control belt connected to the output shaft of the third motor and infrared rangefinders fixedly arranged at both ends of the rotating control belt, and fixed frames are installed on both opposite ends of the rotating control belt, and a rotating frame that can rotate in the horizontal direction is installed on the fixed frame, and a rotating column is connected to the rotating frame, and an electric cylinder is embedded in the rotating column, and a fixing plate is fixedly arranged on the telescopic end of the electric cylinder, and a detection camera is arranged at the center position of the fixing plate, and a plurality of crushing cones are also arranged in a ring array on the fixing plate, and the inclination angle of the inner wall of the borehole is measured by two symmetrically arranged infrared rangefinders.

[0016] A drilling measurement method for mineral geology comprises the following steps:

[0017] S1, hole depth measurement, the winding wheel is controlled to rotate by starting the fourth motor, and the connecting cable wound on the winding wheel is gradually lowered, and the lighting base at the end of the connecting cable carrying the measuring control base can be continuously lowered until the measuring control base falls to the bottom of the hole, and then the hole depth data can be obtained by observing the length mark on the connecting cable;

[0018] S2, inclination measurement, during the lowering process of the measurement control base, the third motor is continuously turned on to control the front probe measurement and cleaning mechanism to rotate slowly, and the infrared rangefinders at both ends of the rotating control belt continuously measure the distance between itself and the inner wall of the borehole. The two infrared rangefinders are symmetrically located. Therefore, when the hole is not tilted, the data measured by the two infrared rangefinders are the same, and there is only a slight difference in the unevenness of the inner wall of the borehole. If the data of the two infrared rangefinders change in a cross shape, it means that the borehole is tilted at this time. At this time, the descent of the measurement control base is paused first, and only the rotation of the rotation control belt is controlled. When the difference in the data measured by the two infrared rangefinders is the largest, the rotation is stopped, and then the measurement control base is controlled to descend. At this time, it is only necessary to continuously record the data changes of the two infrared rangefinders to calculate the inclination angle of the borehole;

[0019] S3, visual sampling, during the descent of the measurement control base, the inner wall of the borehole is observed through the sampling monitoring camera. When sampling is required, the type of sampling object is first determined. If it is a soft material, such as soil, the sampling cylinder of the flexible material collection component is controlled to be aligned with the external push drive member. After the external push drive member is inserted into the sampling cylinder, the sampling cylinder is pushed into the soil to achieve soil sampling;

[0020] If the sampling object is rigid, such as rock, the sampling tube of the rigid material collection assembly is controlled to be aligned with the external push drive member. After the external push drive member is inserted into the sampling tube, the electric push rod is extended and the second motor is turned on, so that the sampling tube is pushed to one side of the rock and can grind the rock in a rotating state, and the rock material is collected into the sampling tube by the material guide spiral groove;

[0021] If the sampling object is liquid, the sampling tube of the liquid material collection assembly is controlled to be aligned with the external push drive member. After the external push drive member is inserted into the sampling tube, the sampling tube is pushed to the inner wall of the borehole to adsorb the liquid in the borehole.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention controls the winding wheel to rotate by starting the fourth motor, and controls the continuous lowering of the measuring control base by connecting the cable until the measuring control base falls to the bottom of the hole. At this time, the hole depth data can be obtained by observing the length mark on the connecting cable.

[0024] 2. In the process of lowering the measurement control base, the infrared rangefinders at both ends of the rotating control belt are controlled to continuously measure the distance between themselves and the inner wall of the borehole. When the hole is not tilted, the data measured by the two infrared rangefinders are the same. When the data of the two infrared rangefinders are transformed in a cross shape, it means that the borehole is tilted at this time. At this time, the descent of the measurement control base is first suspended, and only the rotating control belt is controlled to rotate. When the difference between the data measured by the two infrared rangefinders is the largest, the rotation is stopped, and then the measurement control base is controlled to descend again. At this time, it is only necessary to continuously record the data changes of the two infrared rangefinders to calculate the inclination angle of the borehole.

[0025] 3. When in use, in addition to measuring the hole depth and the inclination angle of the hole, the present invention can also perform real-time image acquisition of the inner wall of the hole during the descent process. When sampling is required, sampling can also be performed through the acquisition structure. The acquisition structure has three different sampling structures for different geological samples. The position of each sampling structure is centrally controlled by a rotating panel. When it is needed, it is moved to one side of the extrapolation drive member. Under the control of the extrapolation drive member, the flexible material collection component can be inserted into the flexible material for sampling, the rigid material collection component can maintain a rotating state to sample and collect rigid materials, and the liquid material collection component can be pushed onto the liquid for adsorption sampling. The structure is flexible, easy to use, and has a wide range of applications.

[0026] 4. The bottom of the present invention is set as a forward detection measurement and cleaning mechanism, which can obtain the inclination angle of the borehole through the cooperation of the infrared rangefinders on both sides, and can also clean the protruding part when a protrusion is found inside the local borehole.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 9As shown, a drilling measurement device for mineral geology includes a measurement control base 1 lowered into a hole and a control console 13 placed on the surface, a winding bracket is arranged on the top of the control console 13, a winding wheel 15 is rotatably connected in the winding bracket, a fourth motor 14 connected to the winding wheel 15 is installed on one side of the top of the control console 13, a connecting cable 12 is wound on the winding wheel 15, a length mark is arranged on the connecting cable 12, and a bottom end of the connecting cable 12 passes through a guide hole 16 on the control console 13 and is connected to a lighting base 10, the bottom of the lighting base 10 is arranged as an inner bevel, a strip light source 11 is arranged on the inner bevel, a fifth motor is embedded in the bottom of the lighting base 10, the top of the measurement control base 1 is rotatably connected to the lighting base 10, and the central axis is fixedly connected to the output shaft of the fifth motor, and space is also reserved on the side wall of the measurement control base 1, which can be used to carry other related sensors for measurement;

[0039] The above structure is the basic structure of the existing drilling measurement equipment. The fourth motor 14 is started to control the rotation of the winding wheel 15, so that the connecting cable 12 wound on the winding wheel 15 is gradually lowered, and then the lighting seat 10 is controlled to carry the measurement control base 1 to continue to be lowered until the measurement control base 1 falls to the bottom of the hole. At this time, the hole depth data can be obtained by observing the length mark on the connecting cable 12. When in use, the lighting seat 10 can continuously illuminate the area below, and the fifth motor can control the rotation of the measurement control base 1.

[0040] A first motor 2 is installed at the center position of both sides of the measurement and control base 1. A rotating panel 3 is fixedly connected to the output shaft of the first motor 2. The rotating panel 3 is rotated by turning on the first motor 2. A sampling monitoring camera 17 is fixedly installed at the center position of the rotating panel 3, which can continuously shoot the inner wall of the borehole. On the one hand, it can be used to observe the inner wall of the borehole, so that the staff can quickly take samples when they see some parts with sampling value. On the other hand, it can be used in conjunction with the sampling structure to shoot the sampling object of the sampling structure and the specific sampling structure of the sampling object to ensure that the sample, the sample position, and the sample collection structure correspond to each other after the sample is taken out to prevent confusion. A plurality of flexible material collection components 4, rigid material collection components 5, and liquid material collection components 6 are installed in a circular array in the rotating panel 3. The flexible material collection components 4, the rigid material collection components 5, and the liquid material collection components 6 are arranged alternately. The side wall of the measurement and control base 1 is also fixedly installed with an extrapolation drive 7 for pushing and driving the flexible material collection component 4, the rigid material collection component 5, or the liquid material collection component 6 to rotate;

[0041] Different from the existing conventional collection structure, the collection structure of the present invention is equipped with three different sampling structures for different geological samples, namely, a flexible material collection component 4, a rigid material collection component 5 and a liquid material collection component 6. The position of each sampling structure is centrally controlled by a rotating panel 3, and it is moved to one side of the extrapolation drive member 7 when needed. Under the control of the extrapolation drive member 7, the flexible material collection component 4 can be inserted into the flexible material for sampling, the rigid material collection component 5 can maintain a rotating state to sample and collect the rigid material, and the liquid material collection component 6 can be pushed onto the liquid for adsorption sampling. The structure is flexible, easy to use, and has a wide range of applications.

[0042] A third motor 8 is installed at the bottom of the measurement and control base 1, and a forward probe measurement and cleaning mechanism 9 is connected to the output shaft of the third motor 8. During the falling process, the aperture is measured and the protruding parts are cleaned at the same time. The forward probe measurement and cleaning mechanism 9 is rotated and controlled by the third motor 8. The forward probe measurement and cleaning mechanism 9 has two functions when in use. One is to perform infrared ranging on the inner walls of the borehole on both sides, and obtain the inclination angle of the borehole by comparing the two data. The second is that when a protrusion is found inside a local borehole, which may affect the lowering of the upper equipment or other equipment in the later stage, the protruding part can also be cleaned.

[0043] The flexible material collection component 4, the rigid material collection component 5 and the liquid material collection component 6 are all composed of an elastic retracting rod 401 fixed on the side wall of the rotating panel 3, a moving sheet 402 installed on the telescopic end of the elastic retracting rod 401, a moving collar 403 fixedly arranged on one side of the moving sheet 402, and a sampling tube 404 rotatably sleeved in the moving collar 403. The sampling tube 404 can rotate in the moving collar 403 without affecting the rotational drive control of the outward driving member 7. When not subjected to other external forces, the elastic retracting rod 401 can retract the moving collar 403 together with the sampling tube 404 onto the rotating panel 3, and align with the inner wall of the borehole. Maintaining a certain distance, when the sampling tube 404 is pushed out by the outward driving rod, the elastic retracting rod 401 can also be adaptively extended to meet the sampling requirements. The sampling tube 404 has a closed structure on one side facing the measurement and control base 1, and an open sampling port on the other side. A cutting ring 405 is provided on the sampling port. The cutting ring 405 is made of high-strength material, which is convenient for direct insertion into the soil and for rapid grinding of rocks. A plug-in slot 406 for inserting and connecting the outward driving member 7 is provided on the side wall of the sampling tube 404 facing the measurement and control base 1, so that one end of the sampling tube 404 can be connected to the outward driving member 7 for rotational drive.

[0044] A colored light bar 407 is provided on the movable sheet 402. The colored light bar 407 on the flexible material collection component 4, the rigid material collection component 5 and the liquid material collection component 6 has different colors. The number of colored light bars 407 on each flexible material collection component 4 is different, the number of colored light bars 407 on each rigid material collection component 5 is different, and the number of colored light bars 407 on each liquid material collection component 6 is different. The colored light bar 407 is turned on when sampling, and other colored light bars 407 remain turned off, so that the sampling position can be roughly marked, and the color and number of the colored light bar 407 can be set to distinguish each sampling barrel 404. After sampling is completed, it is only necessary to compare the colored light bar 407 and the number in the sampling image to determine the area collected by the sampling barrel 404 during sampling, thereby effectively preventing sample confusion.

[0045] The inner wall of the opening of the sampling tube 404 of the rigid material collection component 5 is provided with a material guiding spiral groove 501. When the sampling tube 404 rotates, it can grind and crush the rock. The crushed rock material can enter the sampling tube 404 through the material guiding spiral groove 501 to realize sampling. The sampling tube 404 of the liquid material collection component 6 is filled with an adsorption block 601 for liquid adsorption.

[0046] The outward push drive member 7 consists of an electric push rod 701 fixed in the measurement and control base 1, a second motor 702 connected to the telescopic end of the electric push rod 701, and a plug-in rod 703 fixed on the output shaft of the second motor 702. The plug-in rod 703 can be inserted into the plug-in slot 406 of the sampling tube 404 to form a connection structure that cannot rotate relative to each other. The second motor 702 is extended by controlling the electric push rod 701 to allow the plug-in rod 703 to be inserted into the sampling tube 404. The electric push rod 701 continues to extend to push the sampling tube 404 out and contact the sampling position for sampling. If rigid materials need to be collected, the second motor 702 can be controlled to turn on at the same time.

[0047] The forward detection measurement and cleaning mechanism 9 includes a rotating control belt 901 connected to the output shaft of the third motor 8 and an infrared rangefinder 902 fixedly arranged at both ends of the rotating control belt 901. Fixed frames 903 are installed at opposite ends of the rotating control belt 901. The fixed frame 903 is equipped with a rotating frame 904 that can rotate in the horizontal direction. The rotating frame 904 is connected to a rotating column 905. An electric cylinder 906 is embedded in the rotating column 905. A fixing plate 907 is fixedly arranged on the telescopic end of the electric cylinder 906. A detection camera 908 is arranged at the center of the fixing plate 907. A number of crushing cone spikes 909 are also arranged in a ring array on the fixing plate 907. The inclination angle of the inner wall of the borehole is measured by two symmetrically arranged infrared rangefinders 902. The electric cylinder 906 on the expandable rotating column 905 can push the crushing cone spikes 909 to retract, thereby crushing the protruding part in the borehole, which is convenient for the sinking of the overall equipment.

[0048] A drilling measurement method for mineral geology comprises the following steps:

[0049] S1, hole depth measurement, the winding wheel 15 is controlled to rotate by starting the fourth motor 14, so as to gradually lower the connecting cable 12 wound on the winding wheel 15, and the lighting base 10 at the end of the connecting cable 12 can be continuously lowered with the measuring control base 1 until the measuring control base 1 falls to the bottom of the hole, and then the hole depth data can be obtained by observing the length mark on the connecting cable 12;

[0050] S2, inclination measurement. During the lowering process of the measurement and control base 1, the third motor 8 is continuously turned on to control the front probe measurement and cleaning mechanism 9 to rotate slowly. The infrared rangefinders 902 at both ends of the rotating control belt 901 continuously measure the distance between themselves and the inner wall of the borehole. The two infrared rangefinders 902 are symmetrically located. Therefore, when the hole is not tilted, the data measured by the two infrared rangefinders 902 are the same, and there is only a slight difference in the unevenness of the inner wall of the borehole. If the data of the two infrared rangefinders 902 change in a cross shape, it means that the borehole is tilted at this time. At this time, the measurement and control base 1 is first suspended from descending, and only the rotating control belt 901 is controlled to rotate. When the difference in the data measured by the two infrared rangefinders 902 is the largest, the rotation is stopped, and then the measurement and control base 1 is continued to be controlled to descend. At this time, it is only necessary to continuously record the data changes of the two infrared rangefinders 902 to calculate the inclination angle of the borehole;

[0051] S3, visual sampling, during the descent of the measurement control base 1, the inner wall of the borehole is observed through the sampling monitoring camera 17, and when sampling is required, the type of the sampling object is first determined. If it is a soft material, such as soil, the sampling cylinder 404 of the flexible material collection component 4 is controlled to be aligned with the external push drive member 7, and the external push drive member 7 is inserted into the sampling cylinder 404 and then the sampling cylinder 404 is pushed into the soil, so that soil sampling can be achieved;

[0052] If the sampling object is rigid, such as rock, the sampling barrel 404 of the rigid material collection assembly 5 is controlled to be aligned with the outward driving member 7. After the outward driving member 7 is inserted into the sampling barrel 404, the electric push rod 701 is extended and the second motor 702 is turned on, so that the sampling barrel 404 is pushed to one side of the rock and can grind the rock in a rotating state, and the rock material is collected into the sampling barrel 404 by the material guide spiral groove 501;

[0053] If the sampling object is liquid, the sampling tube 404 of the liquid material collection component 6 is controlled to be aligned with the external push drive member 7. After the external push drive member 7 is inserted into the sampling tube 404, the sampling tube 404 is pushed to the inner wall of the borehole to adsorb the liquid in the borehole.
