Description

Technical Field

[0001] This invention relates to the field of soil testing technology, specifically a portable on-site multi-parameter rapid testing device and method for soil or rock core samples. Background Technology

[0002] Soil, as the cornerstone of agricultural production and an important component of the ecological environment, has physical and chemical parameters (such as moisture content, pH value, electrical conductivity, heavy metal content, nutrient content, etc.) that are directly related to many fields such as crop growth, soil environmental quality assessment, rational use of land resources, and soil pollution prevention and control. Rapidly and accurately obtaining multi-parameter information on soil is a core requirement for the development of modern precision agriculture, soil environmental monitoring, and ecological governance.

[0003] According to Chinese Patent Application No. CN202422147401.1, a portable in-situ multi-parameter soil quality detection device is disclosed. It mainly includes a controller, connecting cables, an optical probe, and sensors. The controller is equipped with a touch screen, a microcontroller circuit board, a microcontroller, an SD card, push-button switches, a wireless communication control board, and a power supply, enabling power management, detection system control, real-time data processing, human-computer interaction, data storage, and remote transmission. The sensors include soil temperature probes, soil moisture probes, soil conductivity probes, and soil pH probes, enabling real-time data acquisition of soil temperature, moisture, conductivity, and pH values. The optical probe includes a ring lamp holder, a light source, a photoelectric sensor, a plano-convex lens, a light-shielding plate, a light-blocking boss, and a light-blocking ring, enabling rapid acquisition of soil organic matter spectral information.

During carrying, transportation, and on-site testing, they are prone to collisions and friction with stones and hard objects in the soil, leading to probe wear, deformation, or even damage. This not only affects the detection accuracy but also shortens the lifespan of the sensor, increases the maintenance and operating costs of the device, and seriously affects the continuity and stability of on-site testing work.

[0010] Preferably, the outer surface of the rotating ring is provided with anti-slip texture, and a limit plate is fixedly installed on the outer circular wall surface of the rotating ring.

[0011] Preferably, the bottom surface of the detection host is provided with a drive chamber, the bottom surface of the drive chamber is provided with a connecting ring, the top surface of the drill rod is provided with a connecting end, and the connecting end is threadedly connected to the connecting ring.

[0012] Preferably, a mounting bracket is fixedly installed on the bottom surface of the drive compartment, a drive motor is fixedly installed on the top surface of the mounting bracket, a mounting hole is opened on the bottom surface of the drive compartment, a connecting ring is rotatably installed on the inner circular wall of the mounting hole, and the shaft of the drive motor is fixedly connected to the connecting ring.

[0013] Preferably, a pressure sensor is provided on the outside of the drill pipe.

[0014] Preferably, a fixing clamp is fixedly installed on one side of the detection host.

[0015] A portable method for rapid on-site multi-parameter detection of soil or rock cores, applicable to any of the portable on-site multi-parameter rapid detection devices for soil or rock cores described above, comprises the following steps: Step 1: Device inspection and preparation. The operator checks the integrity of each component, confirms that the sensor, seal, rotating ring, limit plate and connecting end are properly connected to the connecting ring, starts the detection host to complete the self-test, and ensures that the display screen, sensor, evaluation model and cloud association functions are normal.

[0016] Step 2: Detection Positioning and Device Fixation. Determine the detection point, align the drill bit with the point, and adjust the verticality of the drill rod.

[0017] Step 3: Drill rod insertion and depth positioning. Start the drive motor to drive the drill rod and drill bit to rotate and insert into the soil or rock core. Use the spiral chip guide groove and internal thread groove to ensure stability. After reaching the preset depth, turn off the drive motor.

[0018] Step 4: Sensor extension and retraction adjustment and detection. By moving the rotating ring through the toggle port, the sensor is driven to rise and fall through the screw sleeve, connecting frame, and limit block and limit groove. At the same time, the sealing plate opens the through port, and the sensor contacts the soil or rock core to collect parameters. The limit plate restricts the rotation range.

[0019] Step 5: Data processing and result output. After the detection data is processed by the detection host, it is analyzed through the built-in or cloud-based evaluation model, linked to the land change survey map patches, and the parameters and farmland quality scores are output on the display screen. The operator completes the data storage and transmission.

[0020] Step Six: Inspection and device storage. Reverse the rotation ring to retract the sensor and close the through-hole with the sealing plate. Start the drive motor to reverse and pull out the drill rod. Clean the drill bit, disassemble the drill rod and clamp it into the fixing clamp. Turn off the inspection host to complete the storage.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a connecting frame, the operator can use the toggle port to drive the rotating rod to rotate inside the drill rod via the rotating ring. This converts the rotational motion of the rotating rod into the linear lifting motion of the connecting frame. The connecting frame drives the integrated composite sensing module and the electrochemical heavy metal sensor to lift and lower synchronously, realizing the extension and retraction adjustment of the sensor. When the rotating rod rotates, the bottom seal opens. During detection, the sealing plate lowers with the sensor to open the through-hole, and when not detecting, it rises with the sensor to close the through-hole, achieving sealing protection. Through the coordinated cooperation of the telescopic drive component and the sealing component, when not detecting, the sensor can be retracted into the drill rod via the telescopic drive component. At the same time, the sealing plate closes the through-hole of the sealing ring. This double protection avoids collisions and friction between the sensor and soil, rocks, and hard objects during carrying, transportation, and detection, reducing the probability of sensor damage, extending the service life of the device, and ensuring the continuity and stability of the detection work.

[0022] 2. By setting up a drive motor, during testing, the operator starts the device through the control button on one side of the testing host. The drive motor drives the connecting ring to rotate synchronously, and the rotation of the connecting ring drives the drill rod to rotate synchronously. There is no need for the operator to manually rotate the drill rod, reducing the operation intensity. At the same time, it improves the efficiency and stability of the drill rod insertion into the soil or rock core. The spiral cutting groove on the outside of the drill bit can further reduce the resistance of the soil or rock core during the insertion process, and at the same time, it can remove soil or rock core debris. The internal thread groove on the inner wall of the drill bit can further improve the stability of the drill rod insertion into the soil or rock core. After the test is completed, the operator twists the drill rod to separate the connecting end of the drill rod from the connecting ring, reducing the size of the device and making it easy to carry. At the same time, after disassembly, the drill rod is inserted into the fixing clamp to achieve temporary fixed storage of the drill rod, avoiding damage or loss caused by random placement of the drill rod.

[0025] Please see Figures 1-9 In this embodiment of the invention, a portable on-site multi-parameter rapid detection device for soil or rock core includes: a detection host 1, with a display screen 2 on one side; a control button 3 on one side of the detection host 1; a drill rod 4 on the bottom surface of the detection host 1; a drill bit 5 fixedly mounted on the bottom surface of the drill rod 4, with a spiral chip guide groove 6 on the outer side and an internal thread groove 7 on the inner circular wall surface of the drill bit 5; an integrated composite sensing module 8 inside the drill rod 4; an electrochemical heavy metal sensor 9 on one side of the integrated composite sensing module 8, and a pressure sensor 31 on the outside of the drill rod 4; and a telescopic drive component on the inner bottom surface of the drill rod 4 for telescopically driving the sensor. By setting up the detection host 1, during use, the operator holds the detection host 1 and inserts the drill rod 4 and drill bit 5 into the soil or rock core to be tested. The integrated composite sensing module 8 inside the drill rod 4 integrates a moisture sensor, a pH sensor, and a salinity sensor. The electrochemical heavy metal sensor 9 is separately embedded to isolate interference and avoid crosstalk between acid and alkali signals. The pressure sensor 31 is set on the outside of the drill rod 4 to detect the compaction degree of the soil or rock core. The collected detection data is processed by the internal processing module of the detection host 1 and can be directly analyzed through the built-in farmland quality evaluation model. By calling a preset evaluation model in the cloud for in-depth analysis, and matching the detection data with land change survey patches, the detection host 1 outputs various detection parameters and corresponding farmland quality scores in real time on the display screen 2 on one side. It integrates multiple sensors and integrates multiple detection functions such as moisture, pH, salinity, heavy metals, and compaction into one unit. Multiple soil or rock core physicochemical parameters can be obtained simultaneously by inserting the soil or rock core once, avoiding the drawbacks of needing to insert multiple times or carry multiple devices, improving detection efficiency, and adapting to the needs of rapid survey and emergency monitoring of large areas of soil or rock core.

[0026] exist Figures 3-7 The telescopic drive component includes: a connecting frame 10, which is fixedly installed between the integrated composite sensing module 8 and the electrochemical heavy metal sensor 9; a rotating rod 11, which is rotatably installed on the inner top surface of the drill rod 4; a rotating ring 12, which is fixedly installed on the outside of the rotating rod 11; two actuating ports 13, which are formed on the outer circular wall of the drill rod 4; the outer surface of the rotating ring 12 is provided with anti-slip texture 23; and a limit plate 24 is fixedly installed on the outer circular wall of the rotating ring 12; a lead screw sleeve 14, which is fixedly sleeved on the outside of the rotating rod 11; and a threaded hole 15, which is formed on the top surface of the connecting frame 10 and threadedly connected to the lead screw sleeve 14. Limiting blocks 21 are fixedly installed on both sides of drill rod 4. Two limiting grooves 22 are opened on the inner circular wall of drill rod 4. The limiting blocks 21 and the limiting grooves 22 are movably fitted together. A sealing element is provided on the inner circular wall of drill rod 4 to seal drill rod 4. The sealing element includes: a sealing ring 16, which is fixedly installed on the bottom end of the inner circular wall of drill rod 4; two through holes 17, which are opened on the top surface of sealing ring 16; a mounting ring 18, which is provided on the bottom surface of sealing ring 16; a sealing plate 19, which is fixedly installed on the inner circular wall of mounting ring 18; and a connecting hole 20, which is opened on the top surface of sealing ring 16. The rotating rod 11 passes through the connecting hole 20 and is fixedly connected to the mounting ring 18. By setting up the connecting frame 10, when the drill bit 5 reaches the detection depth, the operator can use the actuating port 13 to actuate the rotating ring 12 with the help of the anti-slip texture 23 on the outside of the rotating ring 12. The rotating ring 12 drives the rotating rod 11 to rotate inside the drill rod 4. At the same time, the lead screw sleeve 14 outside the rotating rod 11 rotates synchronously. Since the lead screw sleeve 14 is threadedly connected to the connecting frame 10, the limiting block 21 and the limiting groove 22 cooperate to restrict the connecting frame 10 from rotating synchronously with the lead screw sleeve 14. Thus, the rotational motion of the rotating rod 11 is converted into the linear lifting motion of the connecting frame 10. The connecting frame 10 drives the integrated composite sensing module 8 and the electrochemical heavy metal sensor 9 to lift synchronously, realizing the extension and retraction adjustment of the sensor. When the rotating rod 11 rotates, the bottom seal opens. When the rotating rod 11 lifts, it drives the safety device. The mounting ring 18 and the sealing plate 19 move synchronously. During detection, the sealing plate 19 opens the through-hole 17 as the sensor descends, and closes the through-hole 17 as the sensor rises when not in detection, thus achieving sealing protection. This not only does not affect the full contact between the sensor and the soil or rock core during detection, but also achieves sealing protection inside the drill rod 4 when not in detection, further improving the protective performance and operational stability of the device. Through the coordinated cooperation of the telescopic drive component and the sealing element, the sensor can be retracted into the drill rod 4 through the telescopic drive component when not in detection, while the sealing plate 19 closes the through-hole 17 of the sealing ring 16. This double protection avoids collision and friction between the sensor and soil, rocks, and hard objects during carrying, transportation, and detection, reducing the probability of sensor damage, extending the service life of the device, and ensuring the continuity and stability of detection work.

[0027] exist Figures 1 to 8 In the test host 1, a drive chamber 25 is provided on the bottom surface, a connecting ring 26 is provided on the bottom surface of the drive chamber 25, a connecting end 27 is provided on the top surface of the drill rod 4, the connecting end 27 is threadedly connected to the connecting ring 26, a mounting bracket 29 is fixedly installed on the bottom surface inside the drive chamber 25, a drive motor 28 is fixedly installed on the top surface of the mounting bracket 29, a mounting hole 30 is opened on the bottom surface of the drive chamber 25, the connecting ring 26 is rotatably installed on the inner circular wall of the mounting hole 30, the shaft of the drive motor 28 is fixedly connected to the connecting ring 26, and a fixing clamp 32 is fixedly installed on one side of the test host 1. By setting up a drive motor 28, during testing, the operator starts the device through the control button 3 on one side of the testing host 1. The drive motor 28 drives the connecting ring 26 to rotate synchronously. When the connecting ring 26 rotates, it drives the drill rod 4 to rotate synchronously. There is no need for the operator to manually rotate the drill rod 4, reducing the intensity of operation. At the same time, it improves the efficiency and stability of the drill rod 4 in inserting into the soil or rock core. The spiral chip guide groove 6 on the outside of the drill bit 5 can further reduce the resistance of the soil or rock core during the insertion process, and at the same time, it can remove soil or rock core debris. The internal thread groove 7 on the inner circular wall of the drill bit 5 can further improve the stability of the drill rod 4 in inserting into the soil or rock core. After the test is completed, the operator twists the drill rod 4 to separate the connecting end 27 of the drill rod 4 from the connecting ring 26, reducing the size of the device and making it easy to carry. At the same time, after disassembly, the drill rod 4 is inserted into the fixing clamp 32 to achieve temporary fixed storage of the drill rod 4, avoiding damage or loss caused by random placement of the drill rod 4.

[0028] A portable method for rapid on-site multi-parameter detection of soil or rock core samples, applicable to any of the above-mentioned portable rapid on-site multi-parameter detection devices for soil or rock core samples, comprises the following steps: Step 1: Device inspection and preparation. The operator checks the integrity of each component and confirms that the sensor, seal, rotating ring 12, limit plate 24 and connecting end 27 are properly connected to the connecting ring 26. The detection host 1 is started to complete the self-test and ensure that the display screen 2, sensor, evaluation model and cloud association functions are normal.

[0029] Step 2: Detection position positioning and device fixation. Determine the detection point, align the drill bit 5 with the point, and adjust the verticality of the drill rod 4.

[0030] Step 3: Insert drill rod 4 and determine depth. Start drive motor 28 to drive drill rod 4 and drill bit 5 to rotate and insert into soil or rock core. Use spiral chip guide groove 6 and internal thread groove 7 to ensure stability. After reaching the preset depth, turn off drive motor 28.

[0031] Step 4: Sensor extension and retraction adjustment and detection. By moving the rotating ring 12 through the toggle port 13, the sensor is driven to rise and fall through the screw sleeve 14, connecting frame 10, and limit block 21 and limit groove 22. At the same time, the sealing plate 19 opens the through port 17, and the sensor contacts the soil or rock core to collect parameters. The limit plate 24 limits the rotation range.

[0032] Step 5: Data processing and result output. After the detection data is processed by the detection host 1, it is analyzed by the built-in or cloud-based evaluation model, associated with the land change survey map patches, and the parameters and cultivated land quality scores are output by the display screen 2. The operator completes the data storage and transmission.

[0033] Step Six: Inspection and device storage. Reverse the rotation ring 12 to retract the sensor, and the sealing plate 19 closes the through-hole 17. Start the drive motor 28 to reverse and pull out the drill rod 4. Clean the drill bit 5, disassemble the drill rod 4 and clamp it into the fixing clamp 32. Turn off the inspection host 1 to complete the storage.

[0034] The working principle of this invention is as follows: During testing, the operator starts the device via control button 3. After the drive motor 28 starts, it drives the connecting ring 26 to rotate. The connecting ring 26 drives the drill rod 4 to rotate synchronously. The operator holds the testing host 1 and inserts the drill rod 4 and drill bit 5 into the soil or rock core to be tested. The drill bit 5 reduces the insertion resistance and removes soil or rock core debris through the spiral chip guide groove 6, and improves the insertion stability through the internal thread groove 7. When the drill bit 5 reaches the testing depth, the operator moves the rotating ring 12 by using the turning port 13 and the anti-slip texture 23 on the outside of the rotating ring 12. The rotating ring 12 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the lead screw sleeve 14 to rotate synchronously. Under the limiting action of the limiting block 21 and the limiting groove 22, the threaded engagement between the lead screw sleeve 14 and the connecting frame 10 converts the rotational motion of the rotating rod 11 into the linear lifting motion of the connecting frame 10. The connecting frame 10 drives the integrated composite sensing module 8 and the electrochemical heavy metal sensor 9 to lift synchronously. When the rotating rod 11 lifts, it drives the mounting ring 18 and the sealing plate 19 to move synchronously. During detection, the sealing plate 19 lowers with the sensor and opens the through-hole 17 of the sealing ring 16. The integrated composite sensing module 8, which integrates a moisture sensor, pH sensor, salinity sensor, and a separately embedded electrochemical heavy metal sensor 9, passes through the penetration port 17 to fully contact the soil or rock core. Simultaneously, the pressure sensor 31 detects the compaction degree of the soil or rock core, enabling the simultaneous acquisition of multiple parameters. After the acquired detection data is processed by the internal processing module of the detection host 1, it can be directly analyzed through the built-in farmland quality evaluation model or through in-depth analysis by calling a preset evaluation model from the cloud. At the same time, the detection data is correlated and matched with the land change survey patches. Finally, the display screen 2 outputs various detection parameters and corresponding farmland quality scores in real time. Operators can complete data storage and transmission operations through the control button 3. The limit plate 24 on the rotating ring 12 limits the rotation amplitude of the rotating ring 12 to avoid damage to the telescopic drive components. After the detection is completed, the control drive motor 28 reverses to drive the drill rod 4 to reverse, making it easy to pull the drill rod 4 out of the soil or rock core. Then, the drill rod 4 is twisted to separate the connecting end 27 from the connecting ring 26. The disassembled drill rod 4 is temporarily stored in the fixing clamp 32, completing the entire detection process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

At the same time, the sealing plate (19) opens the through port (17) so that the sensor can contact the soil to collect parameters. The limiting plate (24) limits the rotation range. Step 5: Data processing and result output. After the detection data is processed by the detection host (1), it is analyzed by the built-in or cloud-based evaluation model, associated with the land change survey plots, and the parameters and farmland quality scores are output by the display screen (2). The operator completes the data storage and transmission. Step 6: Inspection and device storage. Reverse the rotating ring (12) to retract the sensor, and close the through-hole (17) with the sealing plate (19). Start the drive motor (28) to reverse and pull out the drill rod (4), clean the drill bit (5), disassemble the drill rod (4) and insert the fixing clamp (32), and turn off the inspection host (1) to complete the storage.
