Description

Technical Field

[0001] This invention relates to the field of soil moisture detection technology, specifically a mobile and portable integrated drilling and measurement machine for soil moisture monitoring based on a telescopic rod structure. Background Technology

[0002] Soil moisture monitoring is fundamental to hydrological and water resource management, agricultural irrigation guidance, drought relief and disaster reduction, and ecological environment research. Timely and accurate acquisition of volumetric water content data at different soil depths is crucial for scientific decision-making. Currently, field soil moisture monitoring mainly relies on the following technical methods: 1. Traditional manual soil sampling and drying method: This is the most classic and considered the benchmark method. Operators manually drill to the target depth at the monitoring point using tools such as soil drills and shovels, extract soil samples, place them in an aluminum box, and then return to the laboratory to dry them in a drying oven and weigh them. The soil's gravimetric water content is calculated, and then converted to volumetric water content using soil bulk density. Although this method has high accuracy, it has significant drawbacks: cumbersome procedures, extremely long processing time, and high labor intensity; it cannot achieve rapid, multi-point, and continuous monitoring; and it damages the soil structure, making repeated measurements at the same borehole location impossible. 2. Fixed automatic monitoring station method: Sensors (such as time domain reflectance (TDR) and frequency domain reflectance (FDR) sensors) are pre-buried in representative areas, and automatic continuous data acquisition and remote transmission are achieved through data acquisition and wireless transmission modules. The advantages of this method lie in its continuous data and high degree of automation. However, its disadvantages are equally prominent: high construction and maintenance costs; fixed monitoring points with limited spatial representativeness, making it difficult to flexibly reflect spatial variations in regional soil moisture; and the potential for sensor drift or damage due to long-term burial. III. Portable Instrument Separate Measurement Method: This is currently the mainstream method for mobile field monitoring. It typically consists of two parts: a manual or powered (e.g., gasoline engine) soil drill for drilling holes at the measuring points; and a portable TDR or FDR measuring probe and main unit, which is inserted into the borehole wall at different depths after drilling. Compared to the previous two methods, it offers improvements in flexibility and efficiency.

[0003] However, existing technical solutions still have the following inherent drawbacks: The operation process is fragmented and inefficient. Drilling and measurement are two completely separate steps, requiring tool changes and repeated hole alignment, resulting in discontinuous operation and a relatively long overall time consumption. It is highly dependent on manual labor and involves significant physical exertion. Whether drilling manually or using separate drilling rigs and measuring instruments, operators need to expend considerable physical strength, especially in hard soil or scenarios requiring measurements at multiple depths. There is a conflict between portability and operability. To achieve deeper drilling, the soil drill handle or connecting rod is often long and inconvenient to carry; while measuring different depths requires operators to bend over or squat to accurately place the probe at a specific depth, making depth judgment unintuitive, the operating posture uncomfortable, and prone to measurement depth errors. It is highly dependent on borehole quality. Measurement accuracy largely depends on the verticality and smoothness of the borehole wall. Separate operations can easily lead to borehole collapse or deformation, affecting the contact between the probe and the soil, thus introducing measurement errors.

[0004] Based on our practical experience, we have found that existing integrated drilling and measurement machines for soil moisture monitoring can lead to deviations when drilling holes before measurement (for example, the soil moisture detection devices disclosed in patent documents such as CN120468399A and CN118258982A). Because drilling involves pressing the ground downwards and rotating to cut the soil, the soil density is altered due to the compression. Consequently, the data obtained from the soil holes detected by the measurement sensors differs from the mass density of other soils, resulting in a discrepancy between the obtained sensor data and the actual moisture content, leading to inaccurate detection. Summary of the Invention

[0031] The present invention has the following beneficial effects:

[0032] 1. This mobile portable soil moisture monitoring drilling and measurement integrated machine based on a telescopic rod structure uses a rotating plate that is first vertically inserted into the soil. Then, the rotating plate rotates around its short axis to lift the soil and form a pit, thus achieving the total drilling depth. Since the rotating plate only compresses one side of the soil when it digs and lifts, the other sides of the pit remain normal and uncompressed, ensuring that the soil density is the same as that of the rest of the soil. Subsequently, the moisture content of the pit is detected by a sensor, ensuring accurate soil moisture monitoring data.

[0033] 2. This mobile portable soil moisture monitoring drilling and measurement integrated machine based on a telescopic rod structure has a drill rod that rotates downwards to drill a hole. Then, a rotating plate slides downwards and inserts into the soil. The rotating plate then returns to its original position and slides downwards again to dig a second time, thus forming two connected pits in the hole. The total depth of the hole plus the two pits is the total measurement depth. Subsequently, the two pits are measured sequentially by a detection sensor to collect data, thereby reducing measurement errors and improving the accuracy of soil moisture detection.

[0034] 3. This mobile portable soil moisture monitoring drilling and measurement integrated machine based on a telescopic rod structure reduces the total width of the adjustment plate and the rotating plate by sliding the adjustment plate, changing the width of the rotating plate and the adjustment plate and digging downwards a second time, thus forming a structure similar to a countersunk hole, with one hole being larger and the other smaller. By changing the size of the two holes in this way, the detection sensor can detect different hole sizes, improve the fault tolerance rate, optimize the detection data, and thus achieve the original design intention of this application and the expected technical effect of the research and development.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figures 1-3 One type of mobile portable soil moisture monitoring drilling and measurement integrated machine based on a telescopic rod structure includes:

[0048] Base 1;

[0049] Slide 2 is installed on the upper end of base 1, and a first lead screw 3 and a second lead screw 4 are installed inside slide 2 respectively;

[0050] First connecting frame 5 and second connecting frame 6, one end of the first connecting frame 5 is sleeved on the outer surface of the first lead screw 3, and one end of the second connecting frame 6 is sleeved on the outer surface of the second lead screw 4. A sleeve rod 7 is installed at one end of both the first connecting frame 5 and the second connecting frame 6.

[0051] The drive device is installed inside the slide block 2 and drives the first lead screw 3 or the second lead screw 4 to rotate by forward and reverse rotation of the drive device.

[0052] One of the sleeve rods 7 has a drill rod 8 installed at its lower end;

[0053] A detection sensor is installed at the lower end of another sleeve rod 7;

[0054] The upper end of the excavation component 9 is installed at the lower end of the drill rod 8. The excavation component 9 excavates the ground soil to form a pit, and the inner wall of the pit is detected by the detection sensor.

[0055] The excavation component 9 includes a rotating plate 91 slidably connected to the lower end of the drill rod 8. Short shafts 92 are installed at both ends of the rotating plate 91. A connecting sleeve 93 is sleeved on the outer surface of the short shafts 92. A torque spring 94 is connected between the connecting sleeve 93 and the short shafts 92.

[0056] The rotating plate 91 is used to insert into the ground soil. The rotating plate 91 rotates around the short axis 92 as the fulcrum, lifting the soil to form a pit.

[0057] according to Figure 1 As shown, the base 1 is moved to the soil area where drilling is needed. Then, the motor 10 at one end of the second connecting frame 6 drives the sleeve 7 to rotate, which in turn drives the drill rod 8 to rotate. Subsequently, the first servo motor inside the slide ram 2 drives the first lead screw 3 to rotate, causing the first lead screw 3 to slide the second connecting frame 6 downwards. This, in turn, causes the sleeve 7 and drill rod 8 to slide downwards, thus drilling the soil. The drilling depth needs to be reduced by the excavation depth of the rotating plate 91. For example, if a drilling depth of 40cm is required, but the excavation depth is 3cm, then the drill rod 8 only needs to drill downwards 37cm, with the remaining 3cm depth achieved through excavation by the rotating plate 91. Figure 2 As shown, a rotating plate 91 is first vertically inserted into the ground soil. Then, the rotating plate 91 rotates around its short axis 92 as a fulcrum to lift the soil and form a pit, thus achieving a total drilling depth of 40cm. Since the rotating plate 91 only compresses one side of the soil when it digs and lifts, a pit is formed, while the other sides of the pit remain normal and uncompressed, ensuring that the soil density is the same as that of the rest of the soil. Subsequently, the moisture content of the pit is detected by a sensor, ensuring accurate soil moisture detection data.

[0058] It should be noted that after the drill rod 8 and the excavation component 9 have completed drilling and excavation, the first lead screw 3 is reversed by the first servo motor, which drives the motor 10 and the drill rod 8 to reset. Then, the second lead screw 4 is rotated by the second servo motor inside the slide block 2, so that the second lead screw 4 drives the detection sensor to be inserted into the hole and pit to detect the water content in the hole and pit.

[0059] Example 2

[0060] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-3 In this embodiment, an adjusting plate 90 is slidably connected to one end of the rotating plate 91. An adjusting component is installed inside the adjusting plate 90. The adjusting component is used to push the adjusting plate 90 to slide and change the size of the soil pit that the rotating plate 91 rotates and tilts.

[0061] To improve the detection accuracy of the sensor, this embodiment divides the excavation of the pit by the rotating plate 91 into at least two excavations. For example, in Embodiment 1, the excavation depth is 3cm in a single excavation. The sensor can only detect the water content at the 3cm depth, which is a single-stage pit detection and still has errors. Therefore, at least two excavations are used. Specifically, according to... Figure 2 and Figure 3 As shown, the drill rod 8 rotates downwards to drill a hole to a depth of 34 cm, then the rotating plate 91 slides downwards and inserts into the soil. The rotating plate 91 is then rotated, at which point the rotating plate 91 has drilled to a depth of 3 cm. The rotating plate 91 then returns to its original position and slides downwards a second time, thus allowing the rotating plate 91 to drill a second 3 cm, thereby forming two connected pits in the hole. The total depth of the hole plus the two pits is 40 cm, thus achieving the total measurement depth. Subsequently, the two pits are measured sequentially by a detection sensor to collect data, thereby reducing measurement errors and improving the accuracy of soil moisture detection.

[0062] Furthermore, to further improve the fault tolerance and reduce detection errors, this example modifies the size of the two pits, allowing the detection sensor to detect different pit sizes, thereby optimizing the soil moisture detection data. Specifically, according to... Figure 3 As shown, an adjusting plate 90 is installed at one end of the rotating plate 91. By sliding the adjusting plate 90, the contact area between the rotating plate 91 and the soil is expanded, thereby increasing the excavation area. For example, during the first excavation, the total width of the rotating plate 91 and the adjusting plate 90 is 10cm, thus excavating a 10cm pit. Subsequently, during the second excavation, by sliding the adjusting plate 90, the total width of the adjusting plate 90 and the rotating plate 91 is reduced to 6cm, allowing the rotating plate 91 and the adjusting plate 90, with a total length of 6cm, to excavate downwards a second time, thus forming a structure similar to a countersunk hole, with one hole larger and one hole smaller. By changing the size of the two pits in this way, the detection sensor can detect different pit sizes, improving the error tolerance and optimizing the soil moisture detection data.

[0063] Example 3

[0064] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-5In this embodiment, the sleeve 7 includes a round rod 71, a threaded hole 72, a locking block 73, an insert 74, and a threaded plug 75. The upper end of the round rod 71 is equipped with a locking block 73, and the upper end of the locking block 73 is equipped with an insert 74. Both the locking block 73 and the round rod 71 are provided with a threaded hole 72 at one end. The threaded plug 75 is used to insert into the interior of the threaded hole 72.

[0065] According to the testing requirements, several sleeve rods 7 are assembled in this way, and the axes of several sleeve rods 7 are at the same level.

[0066] according to Figure 5 As shown, to facilitate movement and handling, multiple sleeve rods 7 are combined and spliced ​​to the desired length. For example, if the total length of the sleeve rods 7 is 10cm, and a 40cm hole needs to be drilled, four sleeve rods 7 can be assembled to achieve a total length of 40cm. Specifically, the locking block 73 of the first round rod 71 is inserted into the lower end of the previous round rod 71, so that the first locking block 73 corresponds to the threaded hole 72 at the lower end of the previous round rod 71. Then, the threaded plug 75 is screwed into the threaded hole 72 to fix the two round rods 71, thus assembling the two round rods 71. This operation is repeated to complete the assembly of the total length, thereby facilitating movement and handling.

[0067] Example 4

[0068] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 1-8 In this embodiment, the driving device includes a first piston chamber 11 disposed inside the drill rod 8, a piston rod 99 is slidably connected inside the first piston chamber 11, the piston rod 99 is connected to the drill rod 8 by a third spring 28, and a push plate 98 is installed at the lower end of the piston rod 99.

[0069] A second one-way plate 97 is installed at the upper end of the rotating plate 91. The push plate 98 is used to squeeze the second one-way plate 97 and the rotating plate 91 to slide downward, so that the rotating plate 91 can be inserted into the ground soil.

[0070] The connecting sleeve 93 is connected to the drill rod 8 by a fourth spring 96;

[0071] The drill rod 8 is also slidably connected to a second protrusion 13, and the other end of the rotating plate 91 is equipped with a first protrusion 12, which is used to abut against the second protrusion 13.

[0072] The drive unit also includes a first hose 16 disposed inside the drill pipe 8, a pressure relief valve is installed inside the first hose 16, and one end of the first hose 16 is connected to the inside of the first piston chamber 11;

[0073] A square plate 21 is installed on one side of the connecting sleeve 93, and a piston cylinder 17 is installed on one side of the square plate 21. The interior of the piston cylinder 17 is connected to the other end of the first hose 16.

[0074] A piston disc 18 is slidably connected inside the piston cylinder 17. The piston disc 18 and the piston cylinder 17 are connected by a first spring 22. A rack 19 is installed at the other end of the piston disc 18, and a gear 95 is installed at one end of the short shaft 92. The rack 19 and the gear 95 mesh with each other.

[0075] The inner wall of the piston cylinder 17 is also equipped with a spring sheet 23, and the piston disc 18 is used to compress the spring sheet 23 to deform.

[0076] A second hose 24 is also installed on the other side of the piston cylinder 17. A first check valve is installed inside the second hose 24, and a second check valve is installed inside the piston disc 18.

[0077] The drill rod 8 is also provided with a second piston chamber 25. The piston cylinder 17 is used to transfer liquid to the second piston chamber 25. An adjusting rod 14 is slidably connected inside the second piston chamber 25. The lower end of the adjusting rod 14 is connected to the first protrusion 12, and the upper end of the adjusting rod 14 is connected to the inside of the drill rod 8 through a second spring 26.

[0078] Driver: According to Figure 5 As shown, each of the locking blocks 73 has an insertion tube 74 installed at its upper end. After several round rods 71 ​​are assembled, interconnected flow channels are formed inside the round rods 71. The upper end of the flow channel is connected to a hydraulic pipe, which transmits liquid to the inside of the drill pipe 8 through the flow channel. It should be noted that a bearing sealing ring is installed at the lower end of the second connecting frame 6. The drive shaft at the lower end of the motor 10 is connected to the upper end of the first round rod 71, and the lower end of the bearing sealing ring is sleeved on the outer surface of the first round rod 71. One end of the hydraulic pipe is connected to the bearing sealing ring. Thus, when the round rod 71 rotates, its bearing sealing ring does not rotate, and liquid is transmitted to the bearing sealing ring through the hydraulic pipe. The bearing sealing ring then transmits liquid to the flow channel of the round rod 71.

[0079] Subsequently, according to Figure 2 As shown, liquid enters the first piston chamber 11, thereby squeezing the piston rod 99 downwards. The piston rod 99 drives the push plate 98 to slide downwards, squeezing the rotating plate 91 downwards, thus allowing the rotating plate 91 to insert into the soil hole. Since the drill rod 8 has a second protrusion 13 inside, the first protrusion 12 at one end of the rotating plate 91 will abut against the second protrusion 13, thereby limiting the downward sliding distance of the rotating plate 91. For example, if the rotating plate 91 needs to slide downwards and dig 3cm for the first time, the second protrusion 13 limits the first protrusion 12 to only slide downwards by 3cm. After the rotating plate 91 rotates and digs, the second protrusion 13 slides downwards by 3cm, allowing the rotating plate 91 to continue sliding downwards by 3cm, so that the second digging depth of the rotating plate 91 reaches 40cm, thereby achieving the digging effect of the countersunk hole in Embodiment 2.

[0080] When the first protrusion 12 first abuts against the second protrusion 13, the first piston chamber 11 is still continuously filled with liquid, increasing the hydraulic pressure. This increased hydraulic pressure forces open the pressure relief valve inside the first hose 16, allowing the liquid in the first piston chamber 11 to pass through the first hose 16 and enter the piston cylinder 17. Figure 3 As shown, the piston disc 18 and rack 19 slide due to the liquid pressure at the piston cylinder 17. Since the rack 19 meshes with the gear 95, the gear 95 rotates. The gear 95 drives the short shaft 92 to rotate, and the short shaft 92 drives the rotating plate 91 to rotate, thus achieving the rotation of the rotating plate 91 to excavate the soil. Subsequently, according to... Figure 6 As shown, when the piston disc 18 slides to the limit position of the piston cylinder 17, the liquid inside the piston cylinder 17 enters the second hose 24, thereby relieving the internal pressure of the piston cylinder 17, which in turn allows the first spring 22 to pull the piston disc 18 back to its original position, facilitating the next rotation of the drive gear 95 and the rotating plate 91. When the liquid enters the second hose 24, according to... Figure 4 and 8 As shown, liquid is transmitted through the second hose 24 to the inside of the adjusting device and the second piston chamber 25. This causes the adjusting device to push the second connecting bracket 6 to slide, thereby changing the position of the adjusting plate 90 and achieving the reduction of the overall size of the rotating plate 91 in Embodiment 2. Furthermore, the liquid is transmitted through the second hose 24 to the second piston chamber 25, which pushes the adjusting rod 14 downwards, thereby adjusting the downward sliding distance of the first protrusion 12 and achieving the aforementioned effect of changing the position of the first protrusion 12.

[0081] It should be noted that a first check valve is installed inside the second hose 24, and a second check valve is installed inside the piston disc 18, according to... Figure 6 As shown, when the piston disc 18 is reset, its second check valve opens, allowing the liquid on the right side of the piston disc 18 to pass through the second check valve and enter the left side of the piston disc 18. At this time, the check valve inside the second hose 24 is closed, thus ensuring the driving force movement of this application.

[0082] It should be noted that in order to increase the digging force of the rotating plate 91, a spring plate 23 is installed inside the piston cylinder 17. Only when the hydraulic pressure on the right side of the piston disc 18 is greater than the spring force of the spring plate 23, the hydraulic pressure on the right side of the piston disc 18 will squeeze the spring plate 23 to deform, thereby passing over the spring plate 23. At this time, the sliding piston disc 18 will slide quickly under a large hydraulic pressure.

[0083] Alternatively, the drive structure used in this application can be replaced with any drive device, such as a cylinder or hydraulic cylinder.

[0084] Furthermore, a piston cylinder is installed inside the rotating plate 91, which drives the adjusting plate 90 to slide. A pressure relief valve is also installed at one end of the piston cylinder.

[0085] When the device is reset, the pressure relief valve installed at one end of the piston cylinder is triggered. When the push plate 98 stops pressing the rotating plate 91 and slides downward, the fourth spring 96 pulls the rotating plate 91 to reset. Then, the drill rod 8 presses the pressure relief valve of the piston cylinder at one end of the rotating plate 91, so that the hydraulic pressure inside the piston cylinder is discharged. This allows the drive spring inside the piston cylinder to push the adjusting plate 90 to reset, making it convenient for the next use.

[0086] Furthermore, according to Figure 7 and Figure 9 As shown, since the excavation component 9 needs to be inserted into the soil, the soil will get stuck in the cavity at the lower end of the drill rod 8, affecting the rotation and swing of the rotating plate 91. Therefore, a first one-way plate 15 is installed at the lower end of the drill rod 8. The first one-way plate 15 rotates in one direction and works on the same principle as a ratchet. That is, when the drill rod 8 is inserted into the soil, its rack 19 will not rotate, and the soil will be blocked by the rack 19. Then, when the rotating plate 91 slides down, it will squeeze and rub the first one-way plate 15 to rotate and swing down, thereby preventing the soil from entering the lower end of the drill rod 8 without affecting the rotation of the rotating plate 91.

[0087] It should be noted that the first one-way plate 15 and the second one-way plate 97 have the same structure;

[0088] The second one-way plate 97 includes a rotating bar, a stop block and a return spring. The rotating bar is rotatably connected to the upper end of the rotating plate 91. The rotating bar and the rotating plate 91 are connected by the return spring. The upper end of the rotating plate 91 is also equipped with a stop block, which is used to abut against the rotating bar.
