Description

Technical Field

[0001] The present invention relates to the technical field of soil erosion monitoring, and in particular to a multi-point sampling device of a soil erosion monitor and an operating method thereof. Background Art

[0002] Soil erosion monitoring is a crucial technical tool for soil and water conservation research, ecological and environmental assessment, and disaster early warning. Traditional soil erosion monitoring methods typically rely on surface runoff observation, remote sensing image analysis, or tracer element detection. However, these methods are limited in monitoring accuracy, real-time performance, and spatial resolution. In recent years, monitoring devices based on physical sensors have become a research hotspot. These devices enable dynamic monitoring by directly collecting soil parameters (such as moisture, density, and erosion rate).

[0003] Currently, most mainstream soil erosion monitors on the market use single-point sampling or horizontal multi-point sampling designs. For example, some devices deploy multiple sensor probes to perform horizontal sampling at discrete points within the monitoring area to obtain spatially heterogeneous data.

[0004] This type of device has obvious defects in longitudinal (vertical) multi-layer sampling: when continuous monitoring of soil at different depths at the same location is required, existing equipment usually requires multiple insertions or replacements of probe positions. Multiple insertion operations will destroy the original structure of the soil and disturb the natural state of soil layers at different depths, resulting in distorted collected data and an inability to accurately reflect the vertical distribution characteristics of soil erosion. At the same time, the process of repeated positioning, drilling or replacing probes significantly increases manpower and time costs, and it is difficult to capture the soil conditions at different vertical heights at the same point at the same time. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present invention after putting in a lot of creative work.

[0006] Specifically, the technical problem to be solved by the present invention is to provide a multi-point sampling device of a soil erosion monitor and an operation method thereof, so as to solve the technical problem that the current probe is difficult to capture the soil conditions at different vertical heights at the same point at the same time.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0012] As an improved technical solution, the number of the extension components is 1, 2, 3...N, and the height of the fixing tube is consistent with that of the extension components.

[0013] As an improved technical solution, the linkage component 1 and the linkage component 2 have the same structural size. The linkage component 1 includes three connecting rod structures fixed on a guide rail, on which three connecting rod structures are vertically slidably installed at equal intervals. A fixed vertical rod is fixed between the driving ends of the three guide rails, and an assembly rod is fixed to the top of the driving end of the uppermost connecting rod structure.

[0014] As an improved technical solution, the connecting rod structure includes a slider slidably mounted on a guide rail, and two T-shaped rods 2, a vertical plate slidably mounted between the two T-shaped rods 2, and a push-pull rod hingedly mounted between the vertical plate and the slider.

[0015] As an improved technical solution, the driving assembly includes a T-shaped rod fixed to one side of the top of the inner wall of the cover tube, and a screw rod rotatably installed on the top of the cover tube through a bearing, and the top end of the screw rod is located above the cover tube, and an upgrade bar is arranged between the screw rod and the vertical rod end of the T-shaped rod. A sliding hole for the vertical rod end of the T-shaped rod to pass through is opened on one side of the top of the upgrade bar, and a threaded hole threadedly connected to the screw rod is opened on the other side of the top of the upgrade bar.

[0016] As an improved technical solution, the assembly rod includes a fixed rod fixed to the top of the uppermost slider, an extension rod is detachably installed on the top of the fixed rod, an internal threaded slot is coaxially provided at the top of the fixed rod, and a threaded rod threadedly connected to the internal threaded slot is coaxially installed at one end of the extension rod close to the fixed rod.

[0018] As an improved technical solution, the end of the fixed tube away from the conical block is welded with an internal threaded sleeve 1, the top of the extension tube is welded with a hollow external threaded sleeve 1 that is threadedly connected to the two inlet and outlet holes, the top of the extension tube is welded with an internal threaded sleeve 2 that is the same size as the internal threaded sleeve 1, and the end of the cover tube close to the extension component is welded with a hollow external threaded sleeve 2 that is threadedly connected to the second internal threaded sleeve.

[0019] As an improved technical solution, a wire 1 is inserted into the top of the cover tube, and the end of the wire 1 away from the cover tube is connected to the input end of the soil erosion monitor. The linkage component 1 also includes a wire 2, and the detection probe is connected to the wire 2. The fixed tube is connected end to end with the wire 2 inside the conical block, and the wire 2 inside the two adjacent extension components. The head end component inside the topmost extension component is connected end to end with the wire.

[0020] A multi-point sampling device for a soil erosion monitor and an operating method thereof, the specific process is as follows:

[0021] S1: The assembly process of the probe assembly is as follows: the fixed tube and the extension assembly are fixed by threading a hollow externally threaded sleeve 1 and an internally threaded sleeve 1. Two adjacent extension assemblies are fixed by threading a hollow externally threaded sleeve 1 and an internally threaded sleeve 2. The top extension assembly is fixed to the head end assembly by threading a hollow externally threaded sleeve 2 and an internally threaded sleeve 2.

[0022] S2: Insert the fixing pin into the soil and fix the machine cabin on the soil. With the fixing pin as the center point, multiple probe assemblies are distributed and installed around the machine cabin. After determining the installation point of the probe assembly, a drilling machine is used to drill a hole at the point. The depth of the hole needs to be adapted to the height of the probe assembly. After the drilling is completed, the probe assembly is inserted into the hole to complete the installation of the probe assembly embedded in the soil. Then, wire 1 is connected to the access terminal of the soil erosion monitor.

[0023] S3: Drive the upgrade bar on the drive component to move downward, and the upgrade bar presses the top of the linkage component one to move downward. The bottom end of the linkage component one and the top end of the linkage component two are in a state of resistance contact. Therefore, when the linkage component one moves downward, the linkage component two will also be driven to move downward. The detection probes installed on the linkage component one and the linkage component two will be inserted into the soil through the inlet and outlet holes, and the detection probes will be inserted into the soil to contact the soil, and cooperate with the soil erosion monitor to monitor the soil erosion.

[0024] After adopting the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, the probe assembly is composed of three parts: a fixed tube, an extension assembly and a head end assembly, which are detachably assembled and connected. When not in use, it can be disassembled into separate parts modules, which is convenient for storage and transportation. In addition, the extension assembly can be composed of multiple extension assemblies stacked vertically. The corresponding number of extension assemblies can be added according to actual monitoring needs. It is flexible and adaptable to different monitoring requirements.

[0026] 2. In the present invention, the driving component can simultaneously drive the detection probes on the linkage component 1 and the linkage component 2 to be inserted into the soil to achieve linkage, without having to insert the detection probes into the soil one by one. At the same time, when the permanent magnet 1 and the permanent magnet 2 are in a magnetically attracted state, when the driving component drives the upgrade bar to move upward, the linkage component 1 and the linkage component 2 will also be linked to move upward to pull the detection probe out of the soil, thereby realizing the linkage to insert or pull out the detection probe from the soil, facilitating the plugging and unplugging operations of the detection probe and improving work efficiency.

[0027] 3. In the present invention, the assembly rod is provided to ensure that the driving component and the linkage component 1, between two adjacent linkage components 1, and between the linkage component 1 and the linkage component 2 maintain a linkage state. The assembly rod is composed of a threaded connection between an extension rod and a fixed rod. The extension rod is a detachable component to prevent the extension rod from protruding outward when not in use. The extension rod can be disassembled and stored separately, which helps to prevent the extension rod from being damaged by collision.

[0028] 4. The present invention can simultaneously sample multiple points by setting up multiple probe assemblies. At the same time, multiple detection probes are set at the longitudinal position of a single sampling point, which can realize longitudinal multi-point monitoring on the basis of a single point. It is suitable for monitoring soil erosion at different depths. The monitoring is more comprehensive. Moreover, the number of longitudinal monitoring points can be changed and increased by adding different numbers, which is suitable for detection needs at different depths.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] At the same time, the meaning of "and / or" or "and / or" appearing in the full text includes three options. Taking "A and / or B" as an example, it includes option A, or option B, or an option in which both A and B are satisfied.

[0044] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] like Figures 1 to 9As shown together, this embodiment provides a multi-point sampling device for a soil erosion monitor and an operating method thereof. The multi-point sampling device for the soil erosion monitor includes a chamber 1 and three fixing pins 3 installed at the bottom of the chamber 1. A chamber cover is installed at the open top of the chamber 1. A solar panel 4 is installed on the top of the chamber cover via a bracket. The solar panel 4 is a mature existing technology and is therefore not described in detail.

[0046] Multiple probe assemblies 2, a soil erosion monitor is installed inside the cabin 1, and the soil erosion monitor is connected to the probe assembly 2, the probe assembly 2 includes a conical block 21, the top of the conical block 21 is coaxially fixed with a fixed cylinder 22, the top of the fixed cylinder 22 is detachably mounted with an extension assembly, and the end of the extension assembly away from the fixed cylinder 22 is detachably mounted with a head end assembly 24, the extension assembly includes multiple extension assemblies 23, and the multiple extension assemblies 23 are vertically arranged in the shape of a "1", and adjacent extension assemblies 23 are detachably connected;

[0047] The fixed cylinder 22 is internally installed with a linkage component 2 8, the extension component 23 includes an extension cylinder 231, the extension cylinder 231 is internally installed with a linkage component 1 7, the movable ends of the linkage component 1 7 and the linkage component 2 8 are fixedly installed with a detection probe 9, an inlet and outlet hole 1 221 for the detection probe 9 to pass through is provided on one side of the peripheral surface of the fixed cylinder 22 and at a position directly opposite the detection probe 9, and an inlet and outlet hole 232 for the detection probe 9 to pass through is provided on one side of the peripheral surface of the extension cylinder 231 and at a position directly opposite the detection probe 9. The head end component 24 includes a cover cylinder 241, and grips are welded at upper positions on both sides of the peripheral surface of the cover cylinder 241. The drive component 5 is installed inside the cover cylinder 241, and the top of the movable end of the drive component 5 conflicts with the top of the linkage component 1 7;

[0048] When the fixed tube 22, the extension component 23 and the head end component 24 are assembled together, the bottom of the movable end of the driving component 5 conflicts with the top of the linkage component 1 7, and the bottom end of the linkage component 1 7 conflicts with the top of the linkage component 2 8, then the driving component 5 can simultaneously drive the linkage component 1 7 and the linkage component 2 8 to move downward.

[0049] The upgrade bar 53 on the driving component 5 is driven to move downward, and the upgrade bar 53 presses the top of the linkage component 1 7 to move downward. The bottom end of the linkage component 1 7 is in a state of conflicting contact with the top end of the linkage component 2 8. Therefore, when the linkage component 1 7 moves downward, the linkage component 2 8 is also driven to move downward, and the detection probe 9 installed on the linkage component 1 7 and the linkage component 2 8 is inserted into the soil from the inlet and outlet holes. The detection probe 9 is inserted into the soil and contacts the soil, and cooperates with the soil erosion monitor to monitor the soil erosion situation. The driving component 5 can simultaneously drive the detection probes 9 on the linkage component 1 7 and the linkage component 2 8 to be inserted into the soil to achieve linkage, without the need to insert the detection probes 9 into the soil one by one. At the same time, in the magnetic attraction state of the permanent magnet 1 and the permanent magnet 2, when the driving component 5 drives the upgrade bar 53 to move upward, it will also link the linkage component 1 7 and the linkage component 2 8 to move upward, and pull the detection probe 9 out of the soil, thereby realizing the linkage of inserting or pulling out the detection probe 9 into the soil, facilitating the plugging and unplugging operation of the detection probe 9 and improving work efficiency.

[0050] By setting up multiple probe assemblies 2, multiple points can be sampled simultaneously. At the same time, multiple detection probes 9 are set at the longitudinal position of a single sampling point, which can realize longitudinal multi-point monitoring on the basis of a single point, and is suitable for monitoring soil erosion at different depths. The monitoring is more comprehensive, and the number of longitudinal monitoring points can be increased by adding different numbers, which is suitable for detection needs at different depths.

[0051] like Figures 1 to 6 As shown together, in this embodiment, the number of the extension components 23 is 1, 2, 3...N, and the height of the fixing tube 22 is consistent with that of the extension components 23.

[0052] like Figures 4 to 6 As shown together, in this embodiment, the structures and sizes of the linkage component 1 7 and the linkage component 2 8 are consistent. The linkage component 1 7 includes three connecting rod structures 72 fixed on the guide rail 71, which are vertically and evenly slidably installed, and the detection probe 9 is fixed on the movable end of the connecting rod structure 72. A fixed vertical rod 73 is fixed between the driving ends of the three guide rails 71, and an assembly rod 75 is fixed on the top of the driving end of the uppermost connecting rod structure 72. The setting of the assembly rod 75 is used to ensure that the driving component 5 and the linkage component 1 7, between two adjacent linkage components 1 7, and between the linkage component 1 7 and the linkage component 2 8 maintain a linkage state.

[0053] like Figures 6 and 7As shown together, in this embodiment, the connecting rod structure 72 includes a slider 724 slidably mounted on the guide rail 71, and two T-shaped rods 722. A sliding groove is provided on the side of the slider 724 close to the guide rail 71. A vertical plate 721 is slidably mounted between the two T-shaped rods 722, and both ends of the vertical plate 721 are provided with sliding holes for the T-shaped rods 722 to pass through. The detection probe 9 is fixed to the middle of the vertical plate 721 away from the slider 724. A push-pull rod 723 is hingedly installed between the vertical plate 721 and the slider 724. The process of driving the detection probe 9 in and out of the soil is as follows: when the slider 7 When the driven component 5 exerts a downward force 24, the sliding connection between the slider 724 and the guide rail 71 keeps the slider 724 moving straight downward along the guide rail 71. Under the linkage action of the push-pull rod 723, the vertical plate 721 is pushed toward the direction of the detection probe 9 through the push-pull rod 723, thereby prompting the detection probe 9 to pass through the entry and exit hole and insert into the soil. When the slider 724 moves upward, the detection probe 9 is pulled out of the soil through the push-pull rod 723. The three sliders 724 in the same group are fixedly linked by the fixed vertical rod 73, so that each group of three connecting rod structures 72 can achieve synchronous movement.

[0054] like Figure 3 As shown, in this embodiment, the driving assembly 5 includes a T-shaped rod 52 fixed to one side of the top of the inner wall of the cover cylinder 241, and a screw rod 51 rotatably installed on the top of the cover cylinder 241 through a bearing, and the top of the screw rod 51 is located above the cover cylinder 241, and a knob is installed on the top of the cover cylinder 241. An upgrade bar 53 is arranged between the screw rod 51 and the vertical rod end of the T-shaped rod 52. A sliding hole for the vertical rod end of the T-shaped rod 52 is opened on one side of the top of the upgrade bar 53, and a threaded hole threadedly connected to the screw rod 51 is opened on the other side of the top of the upgrade bar 53. The driving assembly 5 drives the upgrade bar 53 to rise and fall as follows: the screw rod 51 is driven to rotate, and under the threaded transmission action of the screw rod 51 and the threaded hole on the upgrade bar 53, and due to the vertical guidance of the upgrade bar 53 by the T-shaped rod 52, the upgrade bar 53 moves downward. Conversely, the screw rod 51 is rotated in the opposite direction to drive the upgrade bar 53 to move upward.

[0055] like Figure 8 As shown, in this embodiment, the assembly rod 75 includes a fixed rod 751 fixed to the top of the uppermost slider 724, and an extension rod 753 is detachably installed on the top of the fixed rod 751. An internal threaded slot 754 is coaxially provided at the top of the fixed rod 751, and a threaded rod 752 threadedly connected to the internal threaded slot 754 is coaxially installed at one end of the extension rod 753 close to the fixed rod 751. The linkage component 7 is composed of a threaded connection between the extension rod 753 and the fixed rod 751. The extension rod 753 is a detachable component to prevent the extension rod 753 from protruding outward when not in use. The extension rod 753 can be disassembled and stored separately, which helps to prevent the extension rod 753 from being damaged by collision.

[0056] like Figure 3 、 Figures 7 and 8 As shown together, in this embodiment, a permanent magnet 1 is embedded in one end of the extension rod 753 away from the fixed rod 751, and a permanent magnet 2 is embedded in one side of the bottom of the upgrade bar 53 and the bottom of the lowest slider 724, and the opposite ends of the permanent magnet 1 and the permanent magnet 2 are in a magnetically attracted state.

[0057] like Figures 3 to 6 As shown together, in this embodiment, an internally threaded sleeve 222 is welded to the end of the fixed tube 22 away from the conical block 21, a hollow externally threaded sleeve 233 threadedly connected to the inlet and outlet hole 232 is welded to the top end of the extension tube 231, an internally threaded sleeve 234 of the same size as the internally threaded sleeve 222 is welded to the top end of the extension tube 231, and a hollow externally threaded sleeve 242 threadedly connected to the internally threaded sleeve 234 is welded to the end of the cover tube 241 close to the extension component 23.

[0058] The assembly process of the probe assembly 2 is as follows:

[0059] The fixed cylinder 22 and the extension component 23 are fixed by threading a hollow external threaded sleeve 233 and an internal threaded sleeve 222, and the two adjacent extension components 23 are fixed by threading a hollow external threaded sleeve 233 and an internal threaded sleeve 234. The top extension component 23 and the head end component 24 are fixed by threading a hollow external threaded sleeve 242 and an internal threaded sleeve 234. The probe component 2 is detachably assembled and connected by three parts: the fixed cylinder 22, the extension component 23 and the head end component 24. When not in use, it can be disassembled into separate parts modules for easy storage and transportation. In addition, the extension component can be composed of multiple extension components 23 stacked vertically, and a corresponding number of extension components 23 can be added according to actual monitoring needs. It is flexible and adaptable to different monitoring requirements.

[0060] like Figures 3 to 6 As shown together, in this embodiment, a wire 6 is inserted into the top of the cover tube 241, and the end of the wire 6 away from the cover tube 241 is connected to the input end of the soil erosion monitor, the linkage component 7 also includes a wire 2 74, and the detection probe 9 is connected to the wire 2 74, the fixed tube 22 and the wire 2 74 inside the conical block 21, and the wire 2 74 inside the two adjacent extension components 23 are connected end to end, and the head end component 24 inside the uppermost extension component 23 is connected end to end with the wire 6.

[0062] S1: The assembly process of the probe assembly 2 is as follows: the fixing cylinder 22 and the extension assembly 23 are fixed by threading the hollow externally threaded sleeve 1 233 and the internally threaded sleeve 1 222. Two adjacent extension assemblies 23 are fixed by threading the hollow externally threaded sleeve 1 233 and the internally threaded sleeve 2 234. The uppermost extension assembly 23 is fixed to the head end assembly 24 by threading the hollow externally threaded sleeve 242 and the internally threaded sleeve 2 234.

[0063] S2: Insert the fixing pin 3 into the soil and fix the machine chamber 1 on the soil. With it as the center point, multiple probe assemblies 2 are distributed and installed around the machine chamber 1. After determining the installation point of the probe assembly 2, first use a drilling machine to drill a hole at the point. The depth of the hole needs to be adapted to the height of the probe assembly 2.
