Description

Technical Field

[0001] This utility model patent relates to the field of meteorological equipment technology, specifically to a portable ground detector. Background Technology

[0002] In meteorological research and related operations, the accurate collection of soil samples is a core step in obtaining crucial data. Parameters such as soil moisture content, composition distribution, and vertical structure play an irreplaceable role in constructing meteorological prediction models, analyzing climate change mechanisms, and optimizing agricultural meteorological services. For example, by analyzing stratified soil samples, the process of moisture exchange between soil and the atmosphere can be quantified, providing data support for drought early warning and farmland irrigation scheduling.

[0003] However, existing soil sampling techniques have significant drawbacks:

[0004] Insufficient equipment portability: Traditional sampling equipment is bulky and heavy (such as vehicle-mounted drilling equipment), relying on large transportation vehicles and professional operation teams, making it difficult to deploy in remote mountainous areas, plateaus, or other complex terrains or areas with limited transportation, which seriously restricts the full coverage of meteorological monitoring networks.

[0005] Functional design limitations: While miniaturization improves portability, it can only collect surface soil samples and cannot meet the needs of stratified sampling at different soil depths. Furthermore, during sampling, the sample is susceptible to oxidation reactions between the equipment material and the soil, or contamination due to structural design flaws (such as open sampling chambers), affecting the accuracy of key indicators such as moisture content.

[0006] Low operational efficiency: The existing equipment has a complex assembly and debugging process, which consumes a lot of time during field operations and requires a high level of technical proficiency from operators. In addition, subsequent sample testing relies on large laboratory instruments, resulting in delayed data processing and failing to meet the real-time analysis needs of meteorological emergency observations.

[0007] To address the aforementioned pain points, the development of a detection device that combines portability, depth adaptability, and non-destructive sampling capabilities has become an urgent need to overcome existing technological bottlenecks and improve the efficiency of meteorological data acquisition. This invention, through the design of a connectable sampling tube, an adaptive ground anchor system, and a contamination-proof sample chamber, effectively solves the problems of sampling accuracy and operational convenience of existing equipment in complex terrain, providing an innovative technical solution for soil parameter monitoring in the meteorological field. Summary of the Invention

[0008] To address some or all of the aforementioned technical problems, this application provides a portable ground detector that has the technical advantage of accurately measuring soil moisture content.

[0009] A portable ground detector includes: a base with a fixed ground anchor; a structural frame fixedly mounted on the base, the structural frame including ring-shaped distributed beams with threads; a lifting platform fitted onto the structural frame; a drive motor mounted on the lifting platform, the drive motor having a threaded ring fitted on the outer side of its drive end, the threaded ring being threadedly connected to the beams; a retaining ring including a mating part connected to the drive motor and a first mating port connected to the mating part; and a sampling tube including a first tube body, a drill bit disposed at the lower end of the first tube body, and a second mating port disposed at the upper end of the first tube body.

[0010] By adopting the above technical solution, a portable ground-based soil sampling instrument was designed. The use of a single-tube operation mode improves sampling accuracy and facilitates monitoring of soil moisture content.

[0011] Optionally, a level is provided on the base, and multiple pin holes are arranged in a ring in the base, with corresponding fixed anchors installed in each pin hole; multiple support rods are arranged in a ring around the edge of any pin hole, the support rods penetrate the base, a reference member is fixedly provided on the lower end face of the multiple support rods, the reference member has an opening for the fixed anchor to pass through, a balance spring is sleeved on the outside of the fixed anchor, and the two ends of the balance spring are fixedly connected to the reference member and the base respectively; a U-shaped retaining ring is fixedly provided on one side of the upper end of the fixed anchor, and a slot for the U-shaped retaining ring to pass through and constrain is provided in the pin hole.

[0012] By adopting the above technical solution and adding a reference component and a U-shaped retaining ring, the vertical sampling accuracy of the device is optimized. This addresses the technical shortcomings of existing sampling devices, such as the need for a level ground or excessive weight, and improves operational efficiency.

[0013] Optionally, the horizontal cross-section of the fixed anchor is a rectangular structure, the aspect ratio of the horizontal cross-section of the fixed anchor is greater than 5, and the width of the horizontal cross-section of the fixed anchor is less than 1 cm.

[0014] By adopting the above technical solution, the structural design of the fixed ground anchor is optimized, avoiding the device from shifting due to the relatively small resistance of the device's fixed constraint.

[0015] Optionally, the first docking port and the second docking port are detachably connected, and an assembly platform for fixing the drive motor is provided on the lifting platform. The assembly platform is fixedly connected to the lifting platform, and the retaining ring passes through the lifting platform.

[0016] Optionally, the mating component includes an interface end, a keyway disposed within the interface end, and an assembly bolt disposed on the interface end. The keyway is constrained by a keyway on the drive end of the drive motor, and the assembly bolt is disposed above the keyway.

[0017] By adopting the above technical solution and using a simple connection structure, manufacturing costs can be reduced.

[0018] Optionally, the drill bit has a ring-shaped cutting tooth, and a blocking structure is provided inside the first tube. The blocking structure includes a crossbeam fixedly installed inside the first tube and a baffle plate installed on the crossbeam. The inclination angle of the crossbeam is consistent with the rotation angle of the thread in the beam. The baffle plate is a spring plate with an arched center, and the upper and lower ends of the baffle plate are connected to the upper and lower ends of the crossbeam.

[0019] By adopting the above technical solution and designing the blocking structure, the sampling sample is prevented from falling, thus improving sampling efficiency. The blocking sheet is an elastic metal spring, and its arching direction is consistent with the sampling direction, preventing the sample from retracting through elastic deformation.

[0020] Optionally, the sampling tube is connected to the splicing rod, which includes a third docking port, a second tube body disposed on the third docking port, and a fourth docking port disposed on the upper end face of the second tube body. The third docking port is detachably connected to the first docking port, and the fourth docking port is detachably connected to the second docking port.

[0021] By adopting the above technical solution, the splicing rod design achieves adaptation to different sampling depths.

[0022] Optionally, a U-shaped guide groove is provided in the base, and a sliding groove is provided in the U-shaped guide groove. The sliding groove is used to slide and constrain the drill bit and the fourth docking port. Ports for the sampling tube and the splicing rod to pass through are provided in the base and the U-shaped guide groove.

[0023] The groove is adapted to the outer diameter of the reference ring of the interface standard part to form a sliding guide fit.

[0024] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of portable ground detectors:

[0025] This technology enables rapid soil sampling, meeting the requirements for moisture content determination. It provides relevant data samples on the effects of drought and sunlight on soil moisture content.

[0026] This device features a simple structure, easy deployment, high accuracy in horizontal sampling and operation, and optimized ground anchors to enhance stability.

[0027] The rectangular cross-section design of the fixed ground anchor reduces the resistance to ground penetration, and the aspect ratio >5 ensures torsional strength and prevents the device from shifting during sampling.

[0028] The barrier expands due to soil pressure when the sampling tube rises and closes due to elastic reset when it descends, preventing the sample from falling. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0038] This application discloses a portable ground detector.

[0039] Reference Figure 1 A portable ground detector includes a base 1, a structural frame, a lifting platform 3, a drive motor 4, and a sampling tube 7. The structural frame is fixedly mounted on the base 1, the lifting platform 3 is mounted on the structural frame, the drive motor 4 is mounted on the lifting platform 3, and the drive motor 4 is connected to the sampling tube 7.

[0040] The structural frame includes ring-shaped distributed beams 2, each beam 2 having threads. A threaded ring 9 is fitted onto the outer side of the drive end of the drive motor 4, and the threaded ring 9 is threadedly connected to the beam 2.

[0041] The base 1 is provided with a port for the through movement of the sampling tube 7.

[0042] When the drive motor 4 is in operation, the drive motor 4 realizes the lifting movement of the lifting platform 3 and the drive motor 4 along the beam 2 through the drive engagement and thread engagement between the threaded ring 9 and the beam 2 in sequence.

[0043] This further drives the up-and-down movement of the sampling tube 7. The sampling tube 7 passes through the base 1 to complete the sampling operation of the soil layer.

[0044] In some embodiments, a retaining ring is provided between the drive motor 4 and the sampling tube 7. The retaining ring includes a docking part 5 connected to the drive motor 4 and a first docking port connected to the docking part 5.

[0045] The sampling tube 7 includes a first tube body, a drill bit disposed at the lower end of the first tube body, and a second docking port disposed at the upper end of the first tube body. The drill bit has annular cutting teeth, which are made of cemented carbide material.

[0046] Among them, combined Figure 3 The first and second docking ports are standard interface components 6. The first and second docking ports are detachably connected. This allows for quick assembly and disassembly of the device, facilitating maintenance while reducing manufacturing costs.

[0047] Interface standard component 6 includes a reference ring, a locking tongue disposed on the reference ring, and a slot disposed within the reference ring. The locking tongue and the slot are arranged opposite to each other and are detachably connected. An opening window is provided on the slot, which is used for the operation opening of the aforementioned constraint separation pressing. The locking tongue / slot structure allows for detachable connection.

[0048] The lower end of the reference ring is fixedly connected to the corresponding component structure.

[0049] Among them, combined Figure 2The mating component 5 includes an interface end, a keyway disposed within the interface end, and an assembly bolt disposed on the interface end. The keyway engages with and constrains the keyway on the drive end of the drive motor 4, and the assembly bolt is disposed above the keyway. A threaded ring 9 is disposed above the interface end.

[0050] The interface end is sleeved on the outside of the drive end of the drive motor 4.

[0051] The assembly bolts are arranged in a ring and pass through the sidewall of the interface end. This is used for the interference fit of the drive motor 4.

[0052] The mating part 5 is detachably connected to the keyway in the drive motor 4 via a keyway, achieving a drive connection with the drive motor 4. The mounting bolts are interference-fitted with the drive motor 4, providing a fixed constraint between the interface end and the drive motor 4.

[0053] This enables the drive motor 4, docking component 5, first docking port, and second docking port to perform transmission and drive functions, achieving the technical objective of rapid loading and unloading of the device.

[0054] In some embodiments, a level 11 is provided on the base 1, and a plurality of pin holes 13 are provided in the base 1 in a ring-shaped arrangement, and the corresponding fixed ground anchors 12 are installed in the pin holes 13 respectively.

[0055] The base 1 includes a metal beam plate and a high-strength plastic plate. The base 1 is fixed to the ground by a fixed ground anchor 12.

[0056] A level 11 is added to facilitate the horizontal calibration of the device and improve sampling accuracy.

[0057] The structure of using pin holes 13 to constrain and fix the ground anchor 12 facilitates the fixation of the device. It simplifies the operation, shortens the operation process, and solves the technical defect of ground anchor shifting during the ground fixing process.

[0058] In some embodiments, a plurality of support rods 14 arranged in a ring are provided at the edge of any of the pin holes 13, and the support rods 14 penetrate the base 1.

[0059] A reference member 16 is fixedly installed on the lower end face of the plurality of support rods 14. An opening 17 for the fixed ground anchor 12 to pass through is provided in the reference member 16. A balance spring 18 is sleeved on the outside of the fixed ground anchor 12. The two ends of the balance spring 18 are respectively fixedly connected to the reference member 16 and the base 1.

[0060] The design of the support rod 14, the reference component 16, and the balance spring 18 provides horizontal support for the base 1. It is suitable for working on uneven ground.

[0061] This addresses the technical shortcomings of existing designs that require manual leveling and whose built-in leveling devices are too heavy.

[0062] Among them, combined Figure 5 A U-shaped retaining ring is fixedly installed on one side of the upper end of the fixed ground anchor 12, and a slot for the U-shaped retaining ring to pass through and constrain is provided in the pin hole 13.

[0063] The U-shaped retaining ring is constrained to the pin hole 13 by rotational engagement.

[0064] The U-shaped retainer includes a swivel fixed to the fixed ground anchor 12 and a U-shaped retainer installed on the swivel.

[0065] The U-shaped card can be moved through the slot.

[0066] The base 1 passes through the pin hole 13 and is struck at the tail end of the fixed ground anchor 12 to secure it in the ground.

[0067] During the process of fixing the device to the ground, the lower end of the U-shaped clip passes through the slot of the pin hole 13, and then the U-shaped clip is rotated to detachably connect with the base 1.

[0068] Furthermore, the state of the fixed anchors 12 is adjusted by tapping multiple fixed anchors 12.

[0069] The horizontal state of the device is calibrated and adjusted by using the level 11.

[0070] In some embodiments, the horizontal cross-section of the fixed anchor 12 is a rectangular structure, the aspect ratio of the horizontal cross-section of the fixed anchor 12 is greater than 5, and the width of the horizontal cross-section of the fixed anchor 12 is less than 1 cm.

[0071] The structural design of the horizontal section of the fixed ground anchor 12 is optimized to improve its resistance to rotational torque during ground sampling operations and enhance the stability of the device.

[0072] In some embodiments, the first docking port and the second docking port are detachably connected, and the lifting platform 3 is provided with an assembly platform 21 for fixed installation of the drive motor 4. The assembly platform 21 is fixedly connected to the lifting platform 3, and the retaining ring passes through the lifting platform 3.

[0073] The assembly platform 21 has its edges located on the outer side of the structural frame, and its edges are fitted with support legs that are fixedly connected to the lifting platform 3. The assembly platform 21 includes a cross-shaped structure and a rectangular structure.

[0074] A top-mounted drive motor 4 design is adopted. This resolves the conflict between the threaded drive connection between the drive motor 4 and the beam 2, and the fixed installation of the drive motor 4.

[0075] In some embodiments, the drill bit has cutting teeth in a ring-shaped structure.

[0076] Among them, see Figure 4 The first tube is provided with a blocking structure, which includes a crossbeam 71 fixedly installed in the first tube and a baffle plate 72 installed on the crossbeam 71. The inclination angle of the crossbeam 71 is consistent with the rotation angle of the thread in the beam rod 2. The baffle plate 72 is a spring plate with an arched middle. The upper and lower ends of the baffle plate 72 are connected to the upper and lower ends of the crossbeam 71.

[0077] The barrier 72 is an elastic metal spring, and its arching direction is consistent with the sampling direction of the first tube.

[0078] The barrier structure is designed to constrain and block the soil sample entering the first tube, preventing it from falling out and facilitating sampling.

[0079] For areas with loose soil or low soil viscosity, improve sampling efficiency. Avoid manual sampling or needle removal.

[0080] Among them, see Figure 6 The first tube body is connected to the splicing rod 73. The splicing rod 73 includes a third docking port, an additional rod, and a fourth docking port that are fixedly connected in sequence. The third docking port is detachably connected to the first docking port, and the fourth docking port is detachably connected to the second docking port.

[0081] The third and fourth docking ports are interface standard component 6.

[0082] Appropriate splicing rods 73 can be added to perform sampling operations according to the required sampling depth.

[0083] In some embodiments, a U-shaped guide groove 8 is provided in the base 1, and a sliding groove is provided in the U-shaped guide groove 8. The sliding groove is used to slide and constrain the drill bit and the fourth docking port. Ports for the first tube body and the splicing rod 73 to pass through are provided in the base 1 and the U-shaped guide groove 8.

[0084] The U-shaped guide groove 8 is designed to constrain and fix the first tube and splicing rod 73, facilitate the detachable connection between the interface standard parts 6, and achieve auxiliary positioning of the device, thereby improving work efficiency.

[0085] The first tube and the second tube are the same hollow tube unit.

[0086] The diameter of the hollow tube structure is smaller than the diameter of the interface standard part 6.

[0087] The interface standard component 6 has a sliding groove set inside the U-shaped guide groove 8 for sliding motion.

[0088] The hollow tube unit slides along the port on the upper side of the U-shaped guide groove 8.
