Description

Technical Field

[0001] This invention relates to the field of water pollution detection technology, and in particular to a smart water utilization river embankment soil collection device, which is suitable for soil sample collection, online detection and collection location positioning of water conservancy projects such as river embankments and reservoir banks, providing accurate data support for embankment safety hazard investigation and stability analysis. Background Technology

[0002] Water pollution is caused by harmful chemicals that reduce or eliminate the usability of water, polluting the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic, as well as organic toxins like benzene, dichloroethane, and ethylene glycol in wastewater can kill aquatic life and affect the quality of dam soil. The safety and stability of dams are crucial. To prevent the impact of water pollution on dams, regular soil sampling and inspection are necessary. The internal condition of the soil (such as the degree of water pollution, water content, weak interlayers, and seepage channels) is key to assessing its health status. Analyzing key parameters such as soil pollution, moisture content, density, and particle composition helps determine the presence of risks such as leakage, piping, and landslides. Existing soil sampling equipment has the following significant technical shortcomings: Separation of collection and detection functions: Samples need to be collected using separate tools and then transported to a laboratory or dedicated testing equipment for analysis. The process is cumbersome and time-consuming. In addition, samples are easily contaminated and lose moisture during transportation, which leads to inaccurate test data. Multiple sample collection is complex: only one set of samples can be collected at a time. If multi-location and multi-depth comparison testing is required, the storage container needs to be repeatedly disassembled and replaced. The operation is cumbersome and can easily cause cross-contamination of samples, affecting the accuracy of comparison. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing equipment that can only collect one set of samples at a time, resulting in cumbersome and time-consuming processes. This invention proposes a smart water utilization river embankment soil sampling device. The device uses an electric cylinder to drive the sampling components deep into the soil, meeting the needs of sampling at different depths and reducing labor intensity. It supports independent collection and testing of multiple sets of samples, with a sealed and reliable switching process to avoid cross-contamination. The detection data is precisely linked to the sampling location, forming a "location-data" correspondence, providing a complete data chain for embankment safety analysis.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A smart water utilization river embankment soil sampling device includes a control box, four handles fixedly installed on the outside of the control box, a cylinder fixedly installed on the bottom of the control box, a bottom cover fixedly installed on the bottom of the cylinder, and a rotation power unit disposed inside the cylinder. The device also includes: A soil collection mechanism, connected to a rotary power unit, is used to collect soil samples. The soil collection mechanism includes a collection tube, which is fixedly installed at the bottom of a base cover. A rotating shaft is rotatably mounted on the base cover, and a spiral blade is fixedly installed on the outer side of the rotating shaft. The spiral blade cooperates with the inner wall of the collection tube. A fixing plate is fixedly installed on the outside of the collection tube. A rotating support ring is rotatably installed on the outside of the fixing plate. Four soil collection and testing tubes are installed on the outside of the rotating support ring. A collection tube is connected to the outside of the collection tube. The collection tube cooperates with the four soil collection and testing tubes. Four handles are fixedly installed on the outside of the rotating support ring.

[0005] Compared with traditional technologies, the technical advantages of this invention are: it integrates the dual-power acquisition mechanism, electric cylinder, servo motor, spiral blade, hexagonal rod, and line detection module into a single handheld device, achieving full-process automation of "acquisition completion and detection simultaneously recording position".

[0006] No manual intervention is required for sample transport and delivery. The entire process from sample collection to testing is sealed within a closed channel consisting of a collection tube, a soil collection and testing tube, completely solving the data distortion problems caused by traditional sample contamination and moisture loss.

[0007] Creative innovation: It breaks through the traditional model of separate use of "collection tools, testing equipment, and positioning tools". Through the deep collaboration of mechanical structure and intelligent module, it achieves functional integration. It is a systematic innovation of soil testing equipment for river embankments, not a simple superposition of parts.

[0008] Preferably, the control box is internally equipped with a control system, a wireless transmission module, a detector, a power supply and a positioning module, and a top cover is fixedly installed on the top of the control box, with a touch controller on the top of the top cover.

[0009] Preferably, the rotary power unit includes a servo motor, a power rod is mounted on the output shaft of the servo motor, a hexagonal slot is provided on the power rod, a hexagonal rod is slidably installed in the hexagonal slot, a hexagonal hole is provided at the top of the rotary shaft, and the hexagonal rod is slidably connected to the inner wall of the hexagonal hole.

[0010] Preferably, the soil sampling mechanism further includes a pushing unit, which is installed inside the cylinder. The pushing unit includes two electric cylinders, both of which are installed on the inner wall of the cylinder. The same pushing plate is installed on the output shaft of the two electric cylinders, and the pushing plate is fixedly installed on the outside of the hexagonal rod.

[0011] Compared with traditional technologies, the technical advantages of this invention are as follows: it adopts a dual-power collaborative design of "electric cylinder pushing and servo motor rotating": the electric cylinder drives the hexagonal rod and conical cover to penetrate deep into the soil to achieve deep soil collection; the servo motor drives the spiral blade to rotate through the hexagonal rod and rotating shaft, automatically conveying the collected soil upward to the soil collection and testing tube, replacing manual conveying.

[0012] The sliding fit design of the hexagonal rod with hexagonal slots and hexagonal holes realizes the mechanical linkage between "linear drive" and "rotational transmission", ensuring that the two powers do not interfere with each other, work together efficiently, and have a simple structure and reliable transmission.

[0013] It abandons the traditional manual collection and transmission method and replaces manpower with mechanical power, which not only breaks through the limitation of collection depth, but also reduces labor intensity and improves the stability of collection and transmission. It is a fundamental improvement over the traditional collection mechanism.

[0014] Preferably, a conical cover is rotatably mounted on the bottom end of the hexagonal rod, and a conical head is fixedly mounted on the bottom end of the conical cover, with the conical cover in contact with the bottom of the collection tube.

[0015] Preferably, a bearing is fixedly installed inside the conical cover, and the hexagonal rod is fixedly installed with the inner ring of the bearing.

[0016] Preferably, an annular limiting strip is fixedly installed on the inner wall of the rotating support ring, and a rotating groove is opened on the outer side of the fixing plate. The annular limiting strip is slidably connected to the inner wall of the rotating groove. Four soil collection and testing tubes are fixedly installed on the outer side of the rotating support ring. The bottom end of each of the four soil collection and testing tubes is provided with an external thread. A sealing cap is installed on the bottom side of the soil collection and testing tube through the external thread. A soil testing head is provided on the outer side of the soil collection and testing tube, and the soil testing head is connected to the testing instrument.

[0017] Preferably, the top of the rotating support ring is provided with four matching sealing grooves, which are located on the outside of the four soil collection and testing tubes. A sealing strip is fixedly installed at the bottom of the collection tube, and the sealing strip is matched with the matching sealing groove. The four independent soil collection and testing tubes can respectively collect samples from different positions and depths, and the sealing cap ensures long-term preservation of the samples.

[0018] Preferably, the inner side of the annular limiting strip is provided with four elastic grooves, and an elastic locking block is slidably installed in each of the four elastic grooves. The same spring is installed between the elastic locking block and the elastic groove. The inner wall of the rotating groove is provided with four locking grooves, and the elastic locking block is engaged with the locking groove.

[0019] Compared with traditional technologies, the technical advantages of this invention are as follows: the design of a rotating support ring and four independent soil collection and testing tubes allows for the docking of unused collection tubes with other collection tubes simply by rotating the support ring, without the need to disassemble any parts; during switching, the sealing strip at the bottom of the collection tube precisely embeds into the matching sealing groove of the rotating support ring, achieving a sealed connection and preventing soil leakage or contamination.

[0020] The fixing mechanism, consisting of "elastic locking block, spring, and locking groove", ensures that the position of the collection tube is stable after switching and that there is no displacement during the transfer process, thus further guaranteeing the purity of the sample.

[0021] Creative innovation: For the first time, it has achieved "non-disassembly multi-sample switching and sealed storage" for soil collection from river embankments, solving the industry pain points of "cumbersome operation and heavy pollution" in traditional multi-sample collection. The structure is ingeniously designed and highly practical, and is not a simple improvement on the traditional "multi-container stacking".

[0022] The beneficial effects of the intelligent water utilization river embankment soil collection device described in this invention are as follows: 1. A rotary power unit and a push unit are set up. The push unit drives the hexagonal rod and conical cover to penetrate the soil through an electric cylinder to achieve soil collection at different depths. The rotary power unit drives the rotating shaft and spiral blade to rotate through a servo motor, which automatically transports the collected soil to the soil collection and testing tube, replacing manual transport, improving efficiency and reducing labor intensity.

[0023] 2. The equipment integrates a control system, a detector, a positioning module, and a wireless transmission module. After soil samples are collected, they are transported to the collection and testing tube via a spiral blade. The soil detection head detects key parameters in real time, and the positioning module records the collection location synchronously. After the data is processed by the control system, it is displayed via a touch controller or wirelessly transmitted to the backend, realizing the integration of "collection-transmission-detection-positioning-data output".

[0024] 3. Four soil collection and testing tubes are evenly arranged on the outside of the rotating support ring. Each collection tube is equipped with a sealing cap and a soil testing head. The sample is switched by rotating the support ring. During switching, the sealing strip and the matching sealing groove are precisely aligned to ensure a seal. The elastic locking block and the locking groove are locked together to prevent displacement after switching. This meets the needs of multi-location and multi-group comparison testing. The sample is sealed throughout the process to avoid contamination.

[0025] 4. Four handles are provided on the outside of the control box for easy gripping and stable operation; a handle is provided on the outside of the rotating support ring for easy manual drive switching; the touch controller intuitively displays data and operation interface, reducing the operating threshold and adapting to field operation scenarios.

[0026] This invention integrates the functions of "power acquisition, automatic transmission, online detection, location positioning, and multi-sample sealing switching" to solve the problems of low efficiency, cumbersome operation, data distortion, and missing positioning of existing equipment, thereby improving the intelligence, accuracy, and convenience of dam soil testing.

[0039] In this embodiment, the installation steps of a smart water utilization river embankment soil sampling device are as follows: 1. Assembly of control box and functional modules: The control system 14, wireless transmission module 15, detector 16, power supply 17, and positioning module 18 are fixed inside the control box 1 with bolts. The circuit lines of each module are connected according to the circuit diagram to ensure normal power supply and signal transmission.

[0040] Weld the four handles 11 evenly to the outside of the control box 1 to ensure a firm installation and even force distribution.

[0041] 2. Assembly of the cylinder and power unit: The cylinder 2 is welded and fixed to the bottom of the control box 1, and the bottom cover 21 is welded and fixed to the bottom of the cylinder 2. The servo motor 81 is fixed to the top of the inner wall of the cylinder 2 with bolts, and the power rod 82 is installed on the output shaft of the servo motor 81 to ensure smooth rotation. Two electric cylinders 651 are symmetrically fixed to the inner wall of the cylinder 2, and the push plate 652 is fixed to the output shaft of the two electric cylinders 651. The position is adjusted to keep the push plate 652 horizontal.

[0042] 3. Soil sampling mechanism assembly: The collection tube 61 is welded and fixed to the bottom of the bottom cover 21, ensuring that it is vertically downward; the rotating shaft 63 is rotatably installed at the center of the bottom cover 21 through the bearing, and the spiral blade 66 is welded and fixed to the outside of the rotating shaft 63. The position is adjusted so that the spiral blade 66 fits against the inner wall of the collection tube 61 and rotates without jamming.

[0043] The bearing 622 is embedded inside the conical cover 62 and fixed. The bottom end of the hexagonal rod 64 is interference-fitted with the inner ring of the bearing 622. The conical head 621 is welded and fixed to the bottom end of the conical cover 62. The conical cover 62 is placed at the bottom of the collection tube 61 to ensure good fit.

[0044] The top end of the hexagonal rod 64 is passed through the hexagonal hole 631 of the rotating shaft 63 and slidably inserted into the hexagonal groove 83 of the power rod 82; the push plate 652 is welded and fixed to the outside of the hexagonal rod 64 to ensure that the electric cylinder 651 can drive the hexagonal rod 64 to slide up and down when it is activated.

[0045] 4. Assembly of the rotating support ring and the collection and detection tube: The fixing plate 4 is welded and fixed to the middle of the outer side of the collection tube 61; the annular limiting strip 52 is welded and fixed to the inner wall of the rotating support ring 5, and the rotating support ring 5 is slidably connected to the rotating groove 41 of the fixing plate 4 through the annular limiting strip 52 to ensure smooth rotation.

[0046] Springs 55 and elastic locking blocks 54 are installed in the four elastic grooves 53 of the annular limiting strip 52 respectively. The position of the elastic locking blocks 54 is adjusted so that they can engage with the locking groove 42 of the rotating groove 41.

[0048] Weld one end of the collection tube 3 to the upper part of the outer side of the collection tube 61, and align the other end with the opening of one of the soil collection and testing tubes 7. Fix the sealing strip 31 at the bottom of the collection tube 3 to ensure that the sealing strip 31 can be embedded in the matching sealing groove 72. Weld the four handles 51 evenly to the outside of the rotating support ring 5.

[0049] 5. Overall debugging: Connect the power supply 17, start the device via the touch controller 13, and test the power-on status of each module; debug the electric cylinder 651, observe the smoothness of the up and down sliding of the hexagonal rod 64 and the conical cover 62, and ensure that the acquisition depth adjustment is normal.

[0050] Debug the servo motor 81 and observe the rotational coordination of the power rod 82, hexagonal rod 64, rotating shaft 63, and spiral blade 66 to ensure the soil conveying mechanism operates normally. Rotate the rotating support ring 5 to test the engagement stability of the elastic locking block 54 and locking groove 42, and the sealing performance of the sealing strip 31 and the matching sealing groove 72; start the soil detection head 9 to test the data transmission, processing, and display effects; test the positioning accuracy of the positioning module 18 to ensure the data and position are correlated normally.

[0051] In this embodiment, the working principle is as follows: when the power supply 17 is turned on, the device is started through the touch controller 13, the control system 14 initializes the status of each module, and the power supply 17 supplies power to all functional modules and power units in the control box 1; the touch controller 13 displays the device operating parameters, battery level, and current location information obtained by the positioning module 18, and the operator can set the acquisition depth, detection parameters, etc. through the touch controller.

[0052] The operator holds the four handles 11 on the outside of the control box 1 with both hands to stabilize the center of gravity of the equipment. The conical head 621 at the bottom of the conical cover 62 is aligned with the location to be collected on the river embankment. The angle of the equipment is adjusted to ensure that the collection tube 61 and the conical cover 62 are perpendicular to the soil surface to avoid collection deviation.

[0053] Manually push the handle 11 downwards to allow the conical cover 62 to be initially inserted into the soil surface under the cutting guidance of the conical head 621, completing the sampling and positioning, and preventing the equipment from shifting during subsequent power sampling.

[0054] The control system 14 activates two electric cylinders 651 by sending a data acquisition command via the touch controller 13. The output shafts of the electric cylinders 651 extend synchronously, pushing the push plate 652 to move downwards in the vertical direction. The push plate 652 drives the hexagonal rod 64 to slide downwards synchronously. The hexagonal rod 64 moves downwards along the hexagonal groove 83 of the power rod 82 and the hexagonal hole 631 of the rotating shaft 63. Through the bearing 622, the conical cover 62 continues to penetrate deeper into the soil, and the penetration depth is executed according to the preset parameters.

[0055] Under the cutting action of the conical head 621, the soil continuously enters the receiving space formed by the conical cover 62 and the collection tube 61. After collection, the control system 14 instructs the output shaft of the electric cylinder 651 to retract, driving the push plate 652, the hexagonal rod 64 and the conical cover 62 to move upward. The soil in the conical cover 62 moves upward and is completely sent into the collection tube 61.

[0056] The control system 14 synchronously starts the servo motor 81, and the output shaft of the servo motor 81 drives the power rod 82 to rotate at a constant speed. The power rod 82 drives the hexagonal rod 64 to rotate synchronously through the hexagonal slot 83. Since the hexagonal rod 64 and the hexagonal hole 631 of the rotating shaft 63 are in sliding fit, the rotational torque is transmitted to the rotating shaft 63, driving the rotating shaft 63 and the outer spiral blade 66 to rotate synchronously.

[0057] The spiral blade 66 forms a closed transmission channel with the inner wall of the collection tube 61. The rotating spiral blade 66 smoothly transmits the soil in the collection tube 61 upward along the tube wall, avoiding soil spillage or residue. After the soil is transmitted to the top of the collection tube 61, it is directionally introduced into the corresponding soil collection and detection tube 7 through the connected collection tube 3, thus completing the soil transmission.

[0058] Online detection and data processing: The soil inside the soil collection and detection tube 7 is in full contact with the soil detection head 9 on the outside. The soil detection head 9 detects key parameters such as soil moisture and compaction in real time, and converts the detection signal into an electrical signal, which is then transmitted to the detector 16. The detector 16 amplifies, calibrates, and analyzes the electrical signal, converting it into intuitive detection data. At the same time, the positioning module 18 acquires information such as latitude, longitude, and altitude of the current collection location and transmits the location information to the control system 14.

[0059] The control system 14 associates and stores the detection data with the location information, and displays it intuitively through the touch controller 13, including the acquisition location, detection parameters, parameter standard range, etc. Operators can use the touch controller 13 to command the wireless transmission module 15 to remotely upload the data to the background management system for subsequent data aggregation and analysis.

[0060] Multiple sample switching collection: When it is necessary to collect soil samples from another location or another depth, the operator first turns off the power unit through the touch controller 13 to ensure that the equipment is in a safe state; then, holding the handle 51 on the outside of the rotating support ring 5, the operator gently pulls the rotating support ring 5 outward, so that the elastic locking block 54 on the inside of the annular limit bar 52 compresses the spring 55 and disengages from the locking groove 42 of the fixed plate 4, thereby releasing the fixed restriction between the rotating support ring 5 and the fixed plate 4.

[0061] Manually rotate the rotating support ring 5 to rotate the unused soil collection and testing tube 7 to below the collection tube 3. When the sealing strip 31 at the bottom of the collection tube 3 is aligned with the matching sealing groove 72 at the top of the rotating support ring 5, release the rotating support ring 5. Under the elastic force of the spring 55, the elastic locking block 54 pops out and locks into the corresponding locking groove 42, thereby fixing the rotating support ring 5.

[0062] At this time, the sealing strip 31 is embedded in the matching sealing groove 72 to achieve a sealed connection between the collection tube 3 and the new soil collection and testing tube 7, avoiding leakage or contamination during soil transfer; move the equipment to the new collection location and repeat the above "deep collection-transfer-detection" process to complete the collection and testing of multiple sets of samples.

[0063] After all samples have been collected, the sealing cap 71 can be unscrewed to remove the samples for laboratory retesting; alternatively, the sealing cap can be kept sealed to preserve the samples for long-term storage, facilitating subsequent traceability and verification.

[0064] Example 2 Example 2 is the same as Example 1 in the rest, except that a modular sensor interface is added to the outside of the soil collection and detection tube 7 to support the expansion of soil pH value, heavy metal ion such as lead, cadmium, pore water pressure and other detection sensors as needed. The sensors are connected in parallel with the original soil detection head 9 to the detector 16. The sensors adopt a waterproof and sealed design to adapt to the humid environment in the field.
