Description

Technical Field

[0001] This invention relates to the field of soil monitoring technology, specifically to a soil environmental monitoring system based on the Internet of Things. Background Technology

[0002] Soil is a critical condition for the growth and survival of existing terrestrial plants. Soil moisture and temperature are also important components, affecting soil physical properties and playing a restrictive role in the dissolution and transfer of soil nutrients and the activity of most microorganisms. Soil environmental monitoring is closely related to human agricultural production activities. Monitoring the soil environment can help us understand changes in the soil environment in real time, so that we can deal with specific problems in a timely manner. To this end, a Chinese patent discloses a soil environmental monitoring device, application number CN202323310630.2. The operator of this patent can adjust the position of the probe rod according to the required monitoring depth to monitor soil at different depths, improving the practicality and adaptability of the soil environmental monitoring device.

[0003] However, when using the system, the probe is directly pushed downwards into the soil without a direct protective structure. The probe is quite sensitive to soil environmental monitoring and analysis. If the soil contains hard impurities such as stones, the probe is easily damaged by direct impact, which reduces the accuracy of the probe's monitoring and analysis or renders it unusable. This increases the probability of probe damage and reduces its lifespan. Therefore, this invention provides an Internet of Things-based soil environmental monitoring system to meet people's needs. Summary of the Invention

[0004] This invention provides an Internet of Things-based soil environment monitoring system, which can effectively solve the problems mentioned in the background art, such as the lack of direct protection structure when the probe is directly pushed down into the soil for monitoring, the sensitivity of the probe itself when monitoring and analyzing the soil environment, and the easy damage caused by direct impact with hard impurities such as stones in the soil. This leads to reduced accuracy of the probe's monitoring and analysis or failure to function properly, thus increasing the probability of probe damage and reducing the lifespan of the probe.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil environment monitoring system based on the Internet of Things, comprising a frame, wherein a soil analyzer is fixedly installed at one end of the top of the frame, and an anti-collision monitoring mechanism is installed at the bottom of the frame;

[0006] The collision avoidance monitoring mechanism includes a drive motor;

[0007] The bottom of the frame is symmetrically equipped with drive motors in the middle. The output shafts of the two drive motors are connected to adjusting screws. An L-shaped lifting block is installed in the middle of each of the two adjusting screws. An auxiliary frame is installed at the bottom of the frame on both sides of the two adjusting screws.

[0008] Each of the two L-shaped lifting blocks has a mounting block movably installed at one end of its bottom. Each of the two mounting blocks has a monitoring probe installed at its bottom end. The auxiliary frame has a movable block movably installed at its bottom end. The movable block has a connecting frame fixedly connected to its bottom end. The connecting frame has a preventive positioning protection rod installed in the middle of its bottom end. The preventive positioning protection rod has a fixing ring fixedly installed on its bottom surface wall. The top and bottom of the fixing ring are equidistantly installed with fine soil protection blades along the circumferential direction.

[0009] According to the above technical solution, a bracket is fixedly installed between the bottom ends of the two auxiliary frames located on the same side. An electric push rod is installed in the middle of the bracket. A displacement pushing plate is fixedly connected to the ends of the two electric push rods. A connecting column is fixedly connected to the middle of one displacement pushing plate. A precision positioning rubber head is fixedly connected to the end of the connecting column. A pressure sensor is fixedly installed in the middle of the other displacement pushing plate.

[0010] Guide frames are symmetrically installed at the bottom end of the frame and at the corresponding position of the adjusting screw. The bottom end of the L-shaped lifting block is provided with a central movable groove. The bottom end of the auxiliary frame is provided with a side movable groove. A metal block is fixedly installed at one end of the bottom of the L-shaped lifting block. A positioning adsorption electromagnetic block is fixedly installed at the middle of one end of the top of the mounting block and the movable block.

[0011] According to the above technical solution, a control button is fixedly installed at the bottom center of the movable block, a reaction force squeezing block is connected to the top of the anti-positioning protection plug, a brittle limiting plate is symmetrically installed in the middle of the connecting frame, an auxiliary notch is opened at one end of the top of the brittle limiting plate, a movable locking block is fixedly connected to one end of the brittle limiting plate, positioning columns are symmetrically installed on both sides of the connecting frame, and a swing limiting block is rotatably installed in the middle of the positioning column;

[0012] A semiconductor thermal laser is fixedly installed at the top center of the mounting block and the movable block. An observation block is embedded in the top center of the frame. A thermochromic metal is symmetrically embedded in the center of the observation block. A ring-shaped marking line is formed on the surface of the thermochromic metal.

[0013] According to the above technical solution, the L-shaped lifting block and the adjusting screw are connected by a thread, one end of the L-shaped lifting block extends to the middle of the guide frame, the L-shaped lifting block and the guide frame are movably connected, and the diameter of the monitoring probe is larger than the diameter of the anti-positioning protection plug rod;

[0014] Both the mounting block and the movable block have a locking block movably connected to one end. The locking block is movably engaged inside the middle movable groove and the side movable groove, respectively. The mounting block and the movable block are slidably connected to the L-shaped lifting block and the auxiliary frame. One end of the movable block and one end of the mounting block are in contact with each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0016] 1. An anti-collision monitoring mechanism is installed. Before the monitoring probe is inserted into the soil, the anti-positioning protection rod is lowered to determine whether there are hard objects such as stones in the soil. This prevents the monitoring probe from colliding directly with hard objects when it is inserted into the soil, which would damage its end and affect its normal use. This protects the monitoring probe.

[0017] The soil-refining blades on the surface of the anti-positioning protection rod are used to chop up the surrounding soil, which helps to prevent the anti-positioning protection rod from descending and refines the soil. When the soil is chopped up, the resistance encountered by the soil-refining blades is transmitted upwards. This works in conjunction with the anti-positioning protection rod to activate multi-directional protection, ensuring that the monitoring probe contacts the refined soil when it descends and is inserted. This prevents impurities such as stones in the surrounding soil from scratching the edge of the monitoring probe. The pre-treatment range is wider to accommodate all positions that the monitoring probe will contact during its descent.

[0018] 2. The drive motor rotates the adjusting screw, which transports the monitoring probe and the preventive positioning protection rod, causing them to descend and insert into the soil. The guide frame guides and limits the L-shaped lifting block, improving the stability of the movement of the monitoring probe and the preventive positioning protection rod. The mechanical transport process is smooth and the speed is uniform, so that the preventive positioning protection rod and the monitoring probe are subjected to uniform force when inserted into the soil, preventing them from being damaged by sudden impacts to the soil due to uneven force.

[0019] Simultaneously, the L-shaped lifting block and auxiliary frame are spliced ​​together, allowing the central and side movable slots to connect. This facilitates the adjustment of the positions of the movable block and mounting block using electric push rods and shifting push plates, thereby adjusting the positions of the monitoring probe and the preventive positioning protection rod. This achieves the function of shifting multiple structures. The adjusting screw can be used to alternately transport the two. The same structure can be shifted to transport and adjust different structures, eliminating the need for multiple transport structures and reducing costs. The positioning adsorption electromagnetic block is used to adsorb and fix the metal block, improving the stability of the L-shaped lifting block, mounting block, and movable block. The mounting block and movable block are pushed to the bottom of the L-shaped lifting block and placed in the same position, which plays a role in mutual positioning of the monitoring probe and the preventive positioning protection rod, ensuring that they are in the same position when descending. Thus, the monitoring probe can accurately descend along the hole formed by the preventive positioning protection rod inserted into the soil, resulting in a more accurate and stable descent position.

[0020] 3. The top of the anti-positioning protection rod is limited and blocked by a brittle limiting plate. The brittle limiting plate has its own characteristics and an auxiliary notch on one side, making it easier to break when squeezed. This makes it more convenient and faster to monitor the resistance encountered by the bottom of the anti-positioning protection rod when it encounters a foreign object.

[0021] Meanwhile, the brittle limiting plate and the connecting frame are interlocked, and the swing limiting block blocks the movable block, making disassembly and installation extremely convenient and facilitating subsequent replacement.

[0022] Meanwhile, the diameter of the protective positioning rod is smaller than that of the monitoring probe, so that when the monitoring probe is embedded in the hole formed by the descent of the protective positioning rod, it can fully contact the soil, preventing the protective positioning rod from squeezing all the soil to one side, which would prevent the end of the monitoring probe from accurately contacting the soil for monitoring and analysis.

[0023] 4. A semiconductor thermal laser moves along with the mounting block and the movable block. The emitted laser carries a certain amount of heat, and a thermochromic metal senses the thermal laser. By detecting the color change caused by the heat, the movement position of the mounting block and the movable block is monitored. This allows for more accurate position determination when the electric push rod adjusts the position of the monitoring probe and the anti-positioning protection rod. This assists workers in determining the position by observing the color change of the thermochromic metal. The position of the monitoring probe and the anti-positioning protection rod below is then checked to determine whether one of them is matched with the L-shaped lifting block for lifting operations. The control operation is more precise, and there is no need to look down to observe the position of the monitoring probe and the anti-positioning protection rod, making it more convenient to use.

[0024] Furthermore, the closer the semiconductor thermal laser is to the thermochromic metal, the wider the range of heat absorption by the thermochromic metal will be, affecting the range of its color change. The range of heat absorption and color change of the thermochromic metal can be compared and monitored using the circular marking line. By observing the range, the staff can effectively determine whether the monitoring probe and the preventive positioning protection plug are in a descending or ascending state, providing a precise auxiliary reference for subsequent control operations.

[0025] 5. Equipped with a precision auxiliary adjustment mechanism, the cleaning motor drives the drive gear and transmission gear to rotate, ensuring that the precision repair wiping cotton adheres tightly to the surface of the monitoring probe. This cleans and wipes away soil adhering to the probe during monitoring, ensuring the cleanliness of the probe surface and preventing excessive soil accumulation from affecting subsequent monitoring processes. Timely removal of adhering impurities also serves to maintain the probe, preventing impurities from hardening and becoming difficult to remove, which could lead to insufficient soil contact during subsequent soil monitoring, affecting the accuracy of soil environmental analysis data. Timely cleaning of the probe reduces the workload of subsequent manual cleaning, decreases the chance of probe damage, and slows down probe aging. In this way, it maintains and protects the probe's monitoring accuracy, improving subsequent monitoring accuracy.

[0026] At the same time, the rotary motor and hydraulic telescopic rod can be used to insert the maintenance roller brush into the positioning maintenance sleeve to clean and maintain the precision repair wiping cotton, remove the dirt left when wiping the monitoring probe, and improve the cleanliness of subsequent wiping.

[0027] 6. By utilizing the swinging of the labor-saving drive linkage, the arc-shaped adjustment drive gear rotates around the fixed rod, which in turn drives the drive rack. This allows for the adjustment of the position of the cleaning motor and the precision repair wiping cotton, enabling them to be moved under the monitoring probe for wiping and maintenance operations, or under the maintenance roller brush for cleaning and maintenance operations, as needed. Furthermore, the length of the labor-saving drive linkage is much greater than the diameter of the arc-shaped adjustment drive gear. Due to the lever principle, the operation is more labor-saving and convenient for the staff.

[0028] Meanwhile, the trapezoidal bidirectional limiting plate can limit and block the force-saving drive linkage, improving the stability of the force-saving drive linkage and drive rack. Both sides of the trapezoidal bidirectional limiting plate are inclined, and the two positions of the force-saving drive linkage can be limited and stabilized by one trapezoidal bidirectional limiting plate. In addition, the trapezoidal bidirectional limiting plate is fixed by adsorption with the positioning metal plate through the fixing magnetic block, which makes the fixing method more convenient and quick, and provides great convenience for subsequent adjustments.

[0029] In summary, by combining the anti-collision monitoring mechanism and the precision auxiliary adjustment mechanism, the soil condition is assessed using a preventative positioning protection rod before the monitoring probe is inserted into the soil. This prevents damage caused by impact and provides pre-protection for the probe's operation. Direct impacts can damage the probe's surface structure, and the impact force can affect its internal structure, thus impacting the probe's accuracy. This reduces the probability of probe damage. Simultaneously, the precision repair wiping cotton is used to clean and maintain the probe after use, reducing the impact of soil adhesion on subsequent monitoring. Prolonged soil adhesion can lead to corrosion and affect the probe's accuracy. Therefore, this mechanism provides a certain degree of precision adjustment. By combining pre-operation preventative protection with post-operation cleaning and maintenance, both protective measures are implemented, extending the lifespan of the monitoring probe.

[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0047] Example: Figure 1-11 As shown, the present invention provides a technical solution, a soil environment monitoring system based on the Internet of Things, including a frame 1, a soil analyzer 2 fixedly installed at one end of the top of the frame 1, and an anti-collision monitoring mechanism 3 installed at the bottom of the frame 1;

[0048] The anti-collision monitoring mechanism 3 includes a drive motor 301, an adjusting screw 302, an L-shaped lifting block 303, an auxiliary frame 304, a mounting block 305, a monitoring probe 306, a movable block 307, a connecting frame 308, a preventive positioning protection plug rod 309, a fixing ring 310, a soil refining protection cutter 311, a bracket 312, an electric push rod 313, a shifting push plate 314, a connecting column 315, a precision positioning rubber head 316, a pressure sensor 317, a guide frame 318, a central movable groove 319, a side movable groove 320, a metal block 321, a positioning adsorption electromagnetic block 322, a control button 323, a reaction force squeezing block 324, a brittle limit plate 325, an auxiliary notch 326, a movable locking block 327, a positioning column 328, a swing limit block 329, a semiconductor thermal laser 330, an observation block 331, a thermochromic metal 332, and a circular marking line 333.

[0049] A drive motor 301 is symmetrically fixedly installed in the middle of the bottom end of the frame 1. The output shafts of the two drive motors 301 are fixedly connected to the adjusting screws 302. An L-shaped lifting block 303 is installed in the middle of the two adjusting screws 302. An auxiliary frame 304 is fixedly installed at the bottom end of the frame 1 on both sides of the two adjusting screws 302.

[0050] Two L-shaped lifting blocks 303 are each movably mounted with a mounting block 305 at one end of their bottom. A monitoring probe 306 is fixedly mounted at the bottom end of each mounting block 305. A movable block 307 is movably mounted at the bottom end of the auxiliary frame 304. A connecting frame 308 is fixedly connected to the bottom end of the movable block 307. A preventive positioning protection rod 309 is installed in the middle of the bottom end of the connecting frame 308. A fixing ring 310 is fixedly installed on the surface wall of the bottom of the preventive positioning protection rod 309. Fine soil protection blades 311 are equidistantly installed at the top and bottom of the fixing ring 310 along the circumferential direction. The L-shaped lifting blocks 303 and the adjusting screw 302 are connected by a threaded connection. The L-shaped lifting block 303 extends to the middle of the guide frame 318, and the L-shaped lifting block 303 and the guide frame 318 are movably connected. The diameter of the monitoring probe 306 is larger than the diameter of the anti-positioning protection plug 309. One end of the mounting block 305 and the movable block 307 are movably connected with a locking block, which is movably engaged in the interior of the middle movable groove 319 and the side movable groove 320, respectively. The mounting block 305 and the movable block 307 are slidably connected to the L-shaped lifting block 303 and the auxiliary frame 304. One end of the movable block 307 and one end of the mounting block 305 are in contact. The anti-positioning protection plug 309 is used to monitor the probe 306. Before insertion into the soil, a descent operation is performed to check for hard objects such as stones. This prevents the monitoring probe 306 from directly colliding with hard objects during insertion, which could damage its tip and affect its normal use. This protects the monitoring probe 306. Simultaneously, the diameter of the positioning protection rod 309 is smaller than that of the monitoring probe 306, ensuring that the monitoring probe 306 can fully contact the soil when inserted into the hole formed by the descent of the positioning protection rod 309. This prevents the positioning protection rod 309 from squeezing all the soil to one side, which could prevent the tip of the monitoring probe 306 from accurately contacting, monitoring, and analyzing the soil. This preventative positioning protection... The soil-refining blades 311 on the surface of the protective rod 309 shred the surrounding soil, which helps to prevent the positioning protection rod 309 from descending and refine the surrounding soil. When the soil-refining blades 311 encounter resistance while refining and shredding the soil, the resistance is transmitted upwards. This works in conjunction with the positioning protection rod 309 to activate multi-directional protection, ensuring that the monitoring probe 306 contacts the refined soil when it descends and is inserted. This prevents impurities such as stones in the surrounding soil from scratching the edges of the monitoring probe 306. The pre-treatment range is wider to accommodate all positions that the monitoring probe 306 contacts when it descends.

[0051] A bracket 312 is fixedly installed between the bottom ends of two auxiliary frames 304 located on the same side. An electric push rod 313 is installed in the middle of the bracket 312. A shifting push plate 314 is fixedly connected to the ends of the two electric push rods 313. A connecting column 315 is fixedly connected to the middle of one shifting push plate 314. A precision positioning rubber head 316 is fixedly connected to the end of the connecting column 315. A pressure sensor 317 is fixedly installed in the middle of the other shifting push plate 314.

[0052] Guide frames 318 are symmetrically installed at the bottom of the frame 1, corresponding to the position of the adjusting screw 302. A central movable groove 319 is opened at the bottom of the L-shaped lifting block 303. Side movable grooves 320 are opened at the bottom of each auxiliary frame 304. A metal block 321 is fixedly installed at one end of the bottom of the L-shaped lifting block 303. A positioning adsorption electromagnetic block 322 is fixedly installed at the middle of one end of the top of both the mounting block 305 and the movable block 307. The length of the shifting push plate 314 is greater than the distance between the two movable blocks 307. The positions of the precise positioning rubber head 316 and the pressure sensor 317 correspond to each other. The metal block 321 and the positioning adsorption... The electromagnetic block 322 is located at the same horizontal level. The drive motor 301 drives the adjusting screw 302 to rotate, which plays a role in conveying the monitoring probe 306 and the anti-positioning protection rod 309, causing them to descend and insert into the soil. The guide frame 318 plays a guiding and limiting role for the L-shaped lifting block 303, which improves the stability of the movement of the monitoring probe 306 and the anti-positioning protection rod 309. The mechanical conveying process is smooth and the speed is uniform, so that the anti-positioning protection rod 309 and the monitoring probe 306 are subjected to uniform force when inserted into the soil, preventing them from being damaged by sudden impact with the soil due to uneven force.

[0053] Meanwhile, the L-shaped lifting block 303 and the auxiliary frame 304 are spliced ​​together, so that the middle movable groove 319 and the side movable groove 320 can be connected to each other. This makes it convenient to use the electric push rod 313 and the shifting push plate 314 to adjust the position of the movable block 307 and the mounting block 305, and then adjust the position of the monitoring probe 306 and the prevention positioning protection plug 309. The adjusting screw 302 can be used to alternately transport the two, which reduces the cost. In addition, the positioning adsorption electromagnetic block 322 is used to adsorb and fix the metal block 321, which improves the stability of the L-shaped lifting block 303, the mounting block 305, and the movable block 307.

[0054] A control button 323 is fixedly installed at the bottom center of the movable block 307. A reaction force squeezing block 324 is connected to the top of the anti-positioning protection plug 309. A brittle limit plate 325 is symmetrically installed in the middle of the connecting frame 308. An auxiliary notch 326 is opened at one end of the top of the brittle limit plate 325. A movable locking block 327 is fixedly connected to one end of the brittle limit plate 325. Positioning posts 328 are symmetrically installed on both sides of the connecting frame 308. A swing limit block 329 is rotatably installed in the middle of the positioning post 328. Slots are symmetrically opened on both sides of the connecting frame 308. The movable locking block 327 is embedded in the slot. The swing limit block 329 is close to the end of the movable locking block 327. The middle of the top of the reaction force squeezing block 324 is connected to the two brittle limit blocks. The bottom of one end of the positioning plate 325 is attached to each other, and the anti-positioning protection rod 309 moves through the middle of the connecting frame 308. The two sides of the reaction force squeezing block 324 are respectively attached to the two side walls of the connecting frame 308. The top of the anti-positioning protection rod 309 is limited and blocked by the brittle limiting plate 325. Utilizing the characteristics of the brittle limiting plate 325 itself, and with an auxiliary notch 326 on one side, it is easier to break when squeezed. It is more convenient and quick to monitor the resistance encountered by the bottom of the anti-positioning protection rod 309 when it encounters a foreign object. At the same time, the brittle limiting plate 325 and the connecting frame 308 are interlocked, and the swing limiting block 329 blocks and limits the movable locking block 327. The disassembly and installation methods are extremely convenient and easy to replace later.

[0055] A semiconductor thermal laser 330 is fixedly mounted at the top center of mounting block 305 and movable block 307. An observation block 331 is embedded at the top center of the frame 1. A thermochromic metal 332 is symmetrically embedded in the center of the observation block 331. A ring-shaped marking line 333 is formed on the surface of the thermochromic metal 332. The semiconductor thermal laser 330 moves with mounting block 305 and movable block 307, emitting laser light with a certain amount of heat. The thermochromic metal 332 senses the thermal laser light and detects the color change caused by the heat, thus monitoring the movement position of mounting block 305 and movable block 307. This allows for more accurate position determination when the electric push rod 313 adjusts the position of monitoring probe 306 and anti-positioning protection plug 309, providing auxiliary position determination for operators. The position of the monitoring probe 306 and the preventive positioning protection rod 309 can be observed by checking the position of the color change. This allows for the determination of whether one of the monitoring probe 306 or the preventive positioning protection rod 309 is matched with the L-shaped lifting block 303 for lifting and lowering operations. This makes the control operation more precise, eliminating the need to look down at the position of the monitoring probe 306 and the preventive positioning protection rod 309, making it more convenient to use. Furthermore, the closer the semiconductor thermal laser 330 is to the thermochromic metal 332, the wider the heat absorption range of the thermochromic metal 332 will be, affecting the range of its color change. The circular marking line 333 can be used to compare and monitor the heat absorption and color change range of the thermochromic metal 332. By observing the range, the staff can effectively determine whether the monitoring probe 306 and the preventive positioning protection rod 309 are in a descending or ascending state, providing a precise auxiliary reference for subsequent control operations.

[0056] A precision auxiliary adjustment mechanism 4 is provided at one end of the bottom of the frame 1;

[0057] The precision auxiliary adjustment mechanism 4 includes a support frame 401, a drive rack 402, a connecting plate 403, a cleaning motor 404, a drive gear 405, a mounting frame 406, a transmission gear 407, a positioning and maintenance sleeve 408, a precision repair wiping cotton 409, a mounting vertical plate 410, a surrounding fixing rod 411, a rotating block 412, an arc-shaped adjustment drive gear 413, a labor-saving drive connecting rod 414, a hydraulic telescopic rod 415, a rotary motor 416, a maintenance roller brush 417, a guide groove 418, a positioning metal plate 419, a movable round rod 420, a trapezoidal bidirectional limiting plate 421, a fixed magnetic block 422, and a connecting rod 423.

[0058] Support frames 401 are symmetrically fixedly installed at one end of the bottom of the frame 1. Drive racks 402 are movably installed at the bottom of both support frames 401. A connecting plate 403 is fixedly connected between the bottoms of the two drive racks 402. A cleaning motor 404 is symmetrically installed at the center of the top of the connecting plate 403. A drive gear 405 is installed at the top of the cleaning motor 404. A mounting bracket 406 is installed on the top of the connecting plate 403, located to one side of the cleaning motor 404. A transmission gear 407 is rotatably installed on the top of the mounting bracket 406. A positioning and maintenance sleeve 408 is embedded in the center of the transmission gear 407. A precision repair wiping cotton 409 is fixedly installed on the inner wall of the positioning and maintenance sleeve 408. The drive gear 405 meshes with the transmission gear 407. The positioning and maintenance sleeve 408, the maintenance roller brush 407, and the monitoring probe 306 are located on the same vertical plane. The cleaning motor 404 drives the drive gear 405 and the transmission gear 407. 7. Rotation ensures that the precision repair wiping cotton 409 adheres tightly to the surface of the monitoring probe 306, effectively cleaning and wiping it to remove soil adhering to its surface during monitoring. This ensures the cleanliness of the monitoring probe 306 surface, preventing excessive soil buildup from affecting subsequent monitoring processes. Timely removal of adhering impurities also helps maintain the monitoring probe 306, preventing it from hardening and becoming difficult to remove. This would hinder subsequent soil monitoring by the monitoring probe 306, affecting the accuracy of soil environmental analysis data. Timely cleaning of the monitoring probe 306 reduces the workload of subsequent manual cleaning, decreases the chance of damage to the probe 306, and slows down its aging. Ultimately, this maintains and protects the monitoring probe 306's accuracy, improving subsequent monitoring precision.

[0059] Mounting vertical plates 410 are symmetrically installed at both ends of the bottom of the frame 1. A surrounding fixing rod 411 is fixedly connected to the bottom end of the mounting vertical plate 410. A rotating block 412 is rotatably installed in the middle of the surrounding fixing rod 411. An arc-shaped adjusting drive gear 413 is fixedly connected to the bottom end of the rotating block 412. A force-saving drive linkage 414 is fixedly connected to the top of the rotating block 412. A connecting rod 423 is fixedly installed between the top ends of the two force-saving drive linkages 414. The two arc-shaped adjusting drive gears 413 are respectively located above the two drive racks 402. The two arc-shaped adjusting drive gears 413 mesh with the two drive racks 402 respectively. The length of the force-saving drive linkage 414 is much larger than the diameter of the arc-shaped adjusting drive gear 413.

[0060] Hydraulic telescopic rods 415 are symmetrically fixedly installed at the bottom of the frame 1 on one side of the mounting vertical plate 410. A rotary motor 416 is fixedly installed at the bottom end of the hydraulic telescopic rod 415. A maintenance roller brush 417 is fixedly connected to the bottom end of the rotary motor 416. The maintenance roller brush 417 can be inserted into the positioning maintenance sleeve 408 by using the rotary motor 416 and the hydraulic telescopic rod 415 to clean and maintain the precision repair wiping cotton 409, remove the dirt left when wiping the monitoring probe 306, and improve the cleanliness of subsequent wiping.

[0061] The top of the frame 1 is symmetrically provided with guide grooves 418. A positioning metal plate 419 is fixedly installed on one side of the guide groove 418 at the top of the frame 1. Movable round rods 420 are movably installed through both ends of the positioning metal plate 419. A trapezoidal bidirectional limiting plate 421 is fixedly connected between the ends of the two movable round rods 420. A fixing magnet 422 is fixedly connected to one end of each of the two movable round rods 420. Two force-saving drive connecting rods 414 are respectively movably inserted through the two guide grooves 418. One end of the trapezoidal bidirectional limiting plate 421 is in contact with the side wall of one of the force-saving drive connecting rods 414. The fixing magnet 422 is tightly attached to the positioning metal plate 419. The fixing magnet 422 and the positioning metal plate 419 are connected. The components 9 are connected by magnetic adsorption. The swinging of the labor-saving drive linkage 414 drives the arc-shaped adjustment drive gear 413 to rotate around the fixed rod 411, which in turn drives the drive rack 402. This adjusts the position of the cleaning motor 404 and the precision repair wiping cotton 409, allowing them to be moved to the underside of the monitoring probe 306 for wiping and maintenance, or to the underside of the maintenance roller brush 417 for cleaning and maintenance, depending on the needs. The length of the labor-saving drive linkage 414 is much greater than the diameter of the arc-shaped adjustment drive gear 413. Due to the lever principle, the operator can operate the components using the labor-saving drive linkage 414, making the process more labor-saving and convenient.

[0062] Meanwhile, the trapezoidal bidirectional limiting plate 421 can limit and block the force-saving drive link 414, improving the stability of the force-saving drive link 414 and the drive rack 402. The trapezoidal bidirectional limiting plate 421 is inclined on both sides, which can accurately fit and limit the two positions of the force-saving drive link 414 after adjustment. Furthermore, the trapezoidal bidirectional limiting plate 421 is fixed to the positioning metal plate 419 by the fixing magnet 422, which is more convenient and quick, and provides great convenience for subsequent adjustments.

[0063] The working principle and usage process of this invention are as follows: First, the staff moves the equipment to the predetermined soil monitoring location, turns on the semiconductor thermal laser 330, and makes it emit laser light with a certain amount of heat. The laser light is captured by the thermochromic metal 332, which changes color when heated. The staff can determine the position of the monitoring probe 306 and the preventive positioning protection plug 309 by observing the distribution of the thermochromic metal 332 that has changed color on the observation block 331.

[0064] Adjustments are made based on the positions of the monitoring probe 306 and the anti-positioning protection rod 309. If the monitoring probe 306 is located on one side of the bottom of the L-shaped lifting block 303, the anti-positioning protection rod 309 corresponds to the bottom of the L-shaped lifting block 303, and no adjustment is needed. If the monitoring probe 306 corresponds to the bottom of the L-shaped lifting block 303, and the anti-positioning protection rod 309 is located on one side of the bottom of the L-shaped lifting block 303, de-energize the positioning adsorption electromagnetic block 322 on the top of the mounting block 305, release its fixed adsorption to the metal block 321, extend an electric push rod 313 forward, and drive the shifting push plate 314 forward. The two ends of the shifting push plate 314 contact the two movable blocks 307 and push them to move. At this time, the central movable groove 319 and the side movable... The movable slot 320 corresponds to and is connected to the movable block 307 and the mounting block 305. The movable block 307 and the mounting block 305 move synchronously, thereby pushing the mounting block 305 and the monitoring probe 306 from one end of the bottom of the L-shaped lifting block 303 to the bottom of the auxiliary frame 304. The movable block 307 moves and engages inside the movable slot 319 until the precise positioning rubber head 316 in the middle of one shifting push plate 314 contacts the pressure sensor 317 in the middle of another shifting push plate 314, thereby controlling the retraction of the electric push rod 313 and opening the positioning adsorption electromagnetic block 322 at the top of the movable block 307. The magnetism generated by the electromagnetic block 322 fixes the metal block 321 at the bottom of the L-shaped lifting block 303, so that the movable block 307 and the anti-positioning protection plug 309 can be firmly connected to the L-shaped lifting block 303.

[0065] Next, the staff controls the drive motor 301 to rotate the adjusting screw 302, which transports the L-shaped lifting block 303 downwards. The L-shaped lifting block 303 moves downwards along the guide frame 318, gradually pushing the anti-positioning protection rod 309 into the soil to be monitored. Meanwhile, the fixing ring 310 and the soil refining and protection blade 311 will chop and loosen the soil around the anti-positioning protection rod 309. The anti-positioning protection rod 309 and the soil refining and protection blade 311 are used to perform advance safety monitoring of the soil where the monitoring probe 306 is about to be inserted. If hard objects such as stones are present in the soil, they will obstruct the soil refining and protection blade 311 and the anti-positioning protection rod 309. This prevents the L-shaped lifting block 303 from descending normally. As the L-shaped lifting block 303 continues to descend, it is obstructed and the resistance is transmitted upward. The brittle limiting plate 325 intercepts and adheres to the top of the reaction force squeezing block 324, which provides vertical pressure and limit for the anti-positioning protection rod 309. The auxiliary notch 326 makes the structural strength of one end of the brittle limiting plate 325 low. Therefore, under the action of a hard object, the brittle limiting plate 325 will be pushed upward and broken. Then, the control button 323 is pressed to stop the drive motor 301 from running, reminding the staff that there is a hard object blocking the soil below. The staff needs to change the monitoring position to prevent the monitoring probe 306 from being damaged by impact.

[0066] If the brittle limiting plate 325 breaks, the operator needs to remove the broken brittle limiting plate 325, push the swing limiting block 329 to one side so that it no longer blocks the movable locking block 327, remove it, and take two new brittle limiting plates 325. The movable locking blocks 327 at the ends of the plates are movably engaged with the two inner walls of the connecting frame 308. The two brittle limiting plates 325 are then pressed tightly against the top of the reaction force pressing block 324. After the operator changes the monitoring position, the operation of preventing the positioning protection rod 309 from falling should be repeated to ensure the safety of the monitoring probe 306 when it falls.

[0067] If the descent of the preventive positioning protection rod 309 proceeds without obstruction, indicating the absence of hard debris in the soil, the drive motor 301 rotates the adjusting screw 302 in the reverse direction, causing the L-shaped lifting block 303 to rise along the guide frame 318, pulling the preventive positioning protection rod 309 out of the soil. This causes the movable block 307 to return to its original position, aligning the central movable slot 319 and the side movable slot 320. Then, the positioning adsorption electromagnetic block 322 is de-energized and no longer adsorbs the metal block 321. The electric push rod 313 near the mounting block 305 extends forward, pushing the mounting block 305 forward. The mounting block 305 then pushes the movable block 307 forward, embedding the mounting block 305 into the central movable slot 319. The positioning adsorption electromagnetic block 322 at the top of the mounting block 305 adsorbs the metal block 321 at the bottom of the L-shaped lifting block 303, fixing the mounting block 305 and the L-shaped lifting block 303 together. Under the operation of the drive motor 301, the L-shaped lifting block 303 and the monitoring... The probe 306 is pushed downwards, allowing it to enter the soil through the hole previously inserted by the anti-positioning protection rod 309. The diameter of the probe 306 is larger than that of the anti-positioning protection rod 309, and the center of the hole is pushed to one side by the rod. The soil shredded by the fine soil protection blade 311 remains around the probe, ensuring a close fit between the probe 306 and the soil during descent. The probe 306 then monitors the soil conditions. Connected to the soil analyzer 2, the probe 306 transmits the monitored information to the analyzer for analysis. This process involves collecting and analyzing soil environmental information. Through the established Internet of Things (IoT), the information can be remotely transmitted and shared. The probe 306 remains embedded in the soil, providing continuous monitoring of the soil environment and enabling timely understanding of changes in soil conditions.

[0068] After monitoring, the staff uses the adjusting screw 302 to raise the monitoring probe 306 from the soil. Once it reaches a certain height, the trapezoidal bidirectional limiting plate 421 is pushed to one side. The movable round rod 420 and the positioning metal plate 419 are movably connected and attracted by the fixed magnetic block 422. The manual pushing force separates the fixed magnetic block 422 and the positioning metal plate 419, so that the trapezoidal bidirectional limiting plate 421 no longer adheres to the force-saving drive linkage 414. The staff then holds the connecting rod 423 and pulls the force-saving drive linkage 414. 14 Slide along the guide groove 418 to the other side, the effort-saving drive linkage 414 will drive the rotating block 412 and the arc-shaped adjusting drive gear 413 to rotate around the fixed rod 411. The arc-shaped adjusting drive gear 413 meshes with the drive rack 402, pushing the drive rack 402 forward along the support frame 401 until the effort-saving drive linkage 414 is in contact with the other side of the guide groove 418, pulling the trapezoidal bidirectional limiting plate 421 to move and fit against one end of the effort-saving drive linkage 414, so that the effort-saving drive linkage 414 no longer shakes.

[0069] At this time, the two positioning and maintenance sleeves 408 move to directly below the two monitoring probes 306 along with the drive rack 402. The drive motor 301 and the adjusting screw 302 drive the monitoring probes 306 to descend and insert them into the interior of the positioning and maintenance sleeves 408. The precision repair wiping cotton 409 wraps tightly against the surface of the monitoring probes 306. The cleaning motor 404 starts and drives the drive gear 405 to rotate, so that it meshes with the transmission gear 407, so that the positioning and maintenance sleeves 408 and the precision repair wiping cotton 409 rotate synchronously. The rotation of the precision repair wiping cotton 409 removes the soil residue adhering to the surface of the monitoring probes 306 when they are inserted into the soil for monitoring, thus cleaning and maintaining the monitoring probes 306 and keeping the surface of the monitoring probes 306 clean.

[0070] After a period of cleaning, the monitoring probe 306 is raised. The staff pushes the two labor-saving drive linkages 414 to move in the opposite direction along the guide groove 418 to the other end. Then, the trapezoidal bidirectional limit plate 421 is used to limit and stabilize it. The arc-shaped adjusting drive gear 413 rotates in the opposite direction and meshes with the drive rack 402 again, pushing the drive rack 402 to move in the opposite direction. This causes the two positioning maintenance sleeves 408 to move in the opposite direction to directly below the two maintenance rollers 417. After a period of time, the soil remaining on the inner wall of the precision repair wiping cotton 409 will dry and solidify. The hydraulic telescopic rod 415 is used to push the rotary motor 416 and the maintenance roller 417 to descend. The maintenance roller 417 descends and inserts into the interior of the positioning maintenance sleeve 408. The rotary motor 416 drives the maintenance roller 417 to rotate, breaking up and removing the soil remaining on the inner wall of the precision repair wiping cotton 409, causing it to fall off automatically.
