Description

Technical Field

[0001] This invention relates to the field of soil moisture monitoring technology, and more specifically, to a soil moisture seepage monitoring device for artificial shrub forests in sandy areas. Background Technology

[0002] Constructing artificial vegetation for sand control has advantages such as high effectiveness, low cost, and convenient implementation. Currently, my country has established large-scale sand-fixing shrub forests, including those of *Caragana korshinskii*, *Populus thunbergii*, *Astragalus membranaceus*, *Salix matsudana*, *Tamarix chinensis*, *Juniperus sabina*, *Haloxylon ammodendron*, *Tamarix chinensis*, and *Calligonum mongolicum*. These shrubs effectively curb desertification, mitigate wind erosion, and promote local habitat restoration. However, with the growth of these artificial shrub forests, water consumption increases, leading to stand degradation, reduced soil moisture, lower groundwater levels, and decreased regional runoff. This threatens the stability of the artificial shrub forests, their ecological benefits, and regional water security. Therefore, monitoring soil moisture seepage in shrub forests is necessary. However, current monitoring devices struggle to detect seepage at different depths. Furthermore, when detecting seepage at different depths at the same location, the top detection device intercepts the water flow, causing significant deviations in the data collected by the lower detection devices. Therefore, it is necessary to provide a soil moisture seepage monitoring device for artificial shrub forests in sandy areas to address the problems mentioned in the background. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a soil moisture infiltration monitoring device for artificial shrub forests in sandy areas, comprising:

[0004] Test soil layer, covering the entire perimeter of the device;

[0005] The upper positioning ring is located slightly above the test soil layer;

[0006] The lower positioning ring is set parallel to the upper positioning ring to restrict the position of the entire device;

[0007] The outer support frame is provided in a ring, with four rings arranged in a circular pattern. The sides fit together, and the upper and lower sides are fixed to the upper and lower positioning ring surfaces, respectively.

[0008] The monitoring devices are arranged in multiple order from the outside to the inside, and are installed inside the outer support frame;

[0009] The inner guide column is fixed to the bottom of the inner monitoring device.

[0010] Furthermore, preferably, the outer support frame includes:

[0011] Right-angle connectors connect the upper positioning ring surface and the lower positioning ring surface respectively;

[0012] The support panel is fixedly connected to right-angle connectors at its top and bottom ends;

[0013] The drainage component is slidably mounted on the inner wall of the support panel and fixedly connected to the monitoring device. With the help of the right-angle connector, the support panel is fixed between the upper and lower positioning rings. When no monitoring is being performed, soil moisture, guided by the monitoring device, flows through the drainage component to the lower layer of the monitoring device, maintaining normal water movement in the soil.

[0014] Furthermore, preferably, the inner wall of the support panel is provided with a sliding groove, and a filter screen is slidably connected to the upper part of the sliding groove, the filter screen being in contact with the inner wall of the support panel. Under the constraint of the sliding groove, the monitoring device drives the drainage component to slide within the sliding groove, thereby pushing the filter screen to slide on the inner wall of the support panel. Under the constraint of the filter screen, soil at the upper inlet of the drainage component is intercepted to prevent soil from clogging the drainage component.

[0015] Furthermore, preferably, the drainage assembly includes:

[0016] A fixed surface, which is fixedly connected to the monitoring device;

[0017] The drainage channel connects the upper and lower sides of the fixed surface, with the upper part of the drainage channel corresponding to the filter screen surface. Under the action of the fixed surface, the drainage channel is divided into an upper inlet and a lower outlet. The upper inlet, under the action of the filter screen surface, filters and collects soil moisture, which is then discharged into the lower soil layer of the monitoring device through the outlet, maintaining normal water infiltration in the soil.

[0018] Furthermore, preferably, the monitoring device includes:

[0019] The lifting columns are arranged in a ring, with four columns in total. The lifting column corresponding to each monitoring device is fixed at the connection point of the monitoring device above it. The outermost set of lifting columns is fixed at the connection point of the support panel.

[0020] The movable panels are arranged in a ring, with four panels parallel to the corresponding support panels;

[0021] The measuring component is fixed on one side to the outer wall of the movable panel and fixedly connected to the fixed surface of the drainage component on the other side.

[0022] Adjustment components connect the movable panel and the measuring components;

[0023] The collection component is located at the connection between the measuring component and the regulating component;

[0024] The limiting plate, fixed to the movable panel, is located on both sides of the adjusting component and connected to the lifting column. Under the action of the lifting column, the movable panel moves up and down, which in turn moves the measuring component, adjusting component, collecting component, and limiting plate up and down, changing the detection depth. Simultaneously, driven by the measuring component, the drainage component slides within the sliding groove, following the movement and causing the filter screen to slide, aligning with the inlet of the drainage channel to filter moisture in the soil. When not detecting, moisture in the soil flows through the adjusting component and the filter screen to the lower soil layer of the monitoring device via the drainage channel. During detection, the adjusting component rotates, disengaging from the collecting component, allowing moisture in the soil to flow through the adjusting component into the collecting component, where it is detected by the measuring component and then discharged.

[0025] Furthermore, preferably, the structure of the inner wall of the movable panel is the same as that of the inner wall of the supporting panel. That is, when not performing any monitoring, each level of the monitoring device can drain water through the drainage assembly, maintaining normal water penetration in the soil.

[0026] Furthermore, preferably, the top of the measuring component is provided with an inclined surface connected to the top of the movable panel, and the bottom is provided with a discharge valve. Under the action of the inclined surface, the moisture in the soil layer corresponding to the monitoring device is guided to facilitate the division of the detection area, and after the detection is completed, the moisture collected in the measuring component is discharged in a timely manner through the discharge valve.

[0027] Furthermore, preferably, the adjustment component includes:

[0028] Two hydraulic shafts are symmetrically distributed and located at both ends of the movable panel, inside the movable panel.

[0029] The telescopic linkage is rotatably mounted on top of the measuring assembly and rotatably connected to the extended end of the hydraulic shaft;

[0030] The rotating shaft is rotatably mounted on the side of the measuring component via a fixing component, and its two ends are fixedly connected to the telescopic connecting rod;

[0031] The seepage surface is fixed on one side to the rotating shaft, and the other side corresponds to the upper part of the drainage channel and is located below the filter screen. The seepage surface has multiple seepage holes. When not being tested, the seepage surface is in contact with the collection component. Under the constraint of the collection component, the seepage holes are closed, and water flows into the drainage component through the filter screen. When water leakage is detected, the extended end of the hydraulic shaft retracts, driving the telescopic connecting rod to rotate and retract. This, in turn, drives the seepage surface to rotate upward through the rotating shaft. As the seepage surface detaches from the collection component, its side contacts the inner wall of the drainage component, sealing the drainage component. Soil water enters the collection component through the seepage holes and is detected by the measuring component.

[0032] Furthermore, preferably, the collection component includes:

[0033] The sealing surface is fixed on the measuring component and corresponds to the seepage surface. A connection channel is provided at the junction of the sealing surface and the seepage surface.

[0034] A toughness-guided surface passes through the connecting channel, with one end set inside the measuring component and the other end fixed to the bottom of the seepage surface;

[0035] The collection chamber is located within the measuring assembly. In other words, when no testing is being performed, the seepage surface is in contact with the sealing surface, and the flexible guiding surface seals the connection channel on the sealing surface. During water leakage testing, the seepage surface detaches from the sealing surface, and simultaneously pulls out the flexible guiding surface, opening the connection channel. Water then flows downwards through the seepage hole, through the connection channel, and guided by the flexible guiding surface, enters the collection chamber. After collection is completed within a predetermined time, the water is transferred to the measuring assembly for testing and recording.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] In this invention, a multi-level monitoring device is set up to detect soil moisture leakage at different depths in sequence. During the detection process, the normal movement of water in the soil is maintained, and the water is promptly transported back into the soil layer after detection to avoid affecting the shrub forest. The position of the monitoring device is adjusted by the lifting column to adjust the monitoring depth according to the actual situation. Attached Figure Description

[0044] Please see Figures 1-5 In this embodiment of the invention, a soil moisture seepage monitoring device for artificial shrub forests in sandy areas includes:

[0045] Test soil layer 1, covering the entire device;

[0046] The upper positioning ring 2 is located slightly above the test soil layer 1;

[0047] The lower positioning ring 3 is set parallel to the upper positioning ring 2 to restrict the position of the entire device.

[0048] The outer support frame 4 is provided in a ring, with four rings distributed in a circular manner. The sides fit together, and the upper and lower sides are fixed to the upper positioning ring surface 2 and the lower positioning ring surface 3, respectively.

[0049] Monitoring devices 5 are arranged in multiple order from the outside to the inside, and are installed inside the outer support frame 4;

[0050] The inner guide column 6 is fixed to the bottom of the inner monitoring device 5.

[0051] In this embodiment, the outer support frame 4 includes:

[0052] Right-angle connector 41 connects the upper positioning ring 2 and the lower positioning ring 3 respectively;

[0053] The support panel 42 is fixedly connected to the right-angle connector 41 at its upper and lower ends, respectively.

[0054] The drainage component 43 is slidably mounted on the inner wall of the support panel 42 and fixedly connected to the monitoring device 5. Under the action of the right-angle connector 41, the support panel 42 is fixed between the upper positioning ring 2 and the lower positioning ring 3. When no detection is performed, the soil moisture is guided by the monitoring device 5 and flows through the drainage component 43 to the lower layer of the monitoring device 5, maintaining the normal movement of moisture in the soil.

[0055] In this embodiment, a sliding groove 421 is provided on the inner wall of the support panel 42, and a filter screen 422 is slidably connected to the upper part of the sliding groove 421. The filter screen 422 is in contact with the inner wall of the support panel 42. Under the constraint of the sliding groove 421, the monitoring device 5 drives the drainage component 43 to slide within the sliding groove 421, thereby pushing the filter screen 422 to slide on the inner wall of the support panel 42. Under the constraint of the filter screen 422, the soil at the upper inlet of the drainage component 43 is intercepted to prevent the soil from clogging the drainage component 43.

[0056] In this embodiment, the drainage component 43 includes:

[0057] Fixed surface 431 is fixedly connected to monitoring device 5;

[0058] The drainage channel 432 connects the upper and lower sides of the fixed surface 431, and the upper part of the drainage channel 432 corresponds to the filter screen surface 422. Under the action of the fixed surface 431, the drainage channel 432 is divided into an upper inlet and a lower outlet. The upper inlet, under the action of the filter screen surface 422, filters and collects soil moisture, which is then discharged into the lower soil layer of the monitoring device 5 through the outlet, maintaining normal water infiltration in the soil.

[0059] In this embodiment, the monitoring device 5 includes:

[0060] The lifting columns 51 are arranged in a ring. Each level of monitoring device 5 has a corresponding lifting column 51 fixed at the connection point of the previous level monitoring device 5. The outermost set of lifting columns 51 is fixed at the connection point of the support panel 42.

[0061] The movable panels 52 are arranged in a ring, with four of them parallel to the corresponding support panels 42;

[0062] The measuring component 53 is fixed on one side to the outer wall of the movable panel 52, and the other side is fixedly connected to the fixing surface 431 of the drainage component 43.

[0063] Adjustment component 54 connects the movable panel 52 and the measuring component 53;

[0064] The collecting component 55 is located at the connection between the measuring component 53 and the adjusting component 54;

[0065] The limiting plate 56, fixed on the movable panel 52, is located on both sides of the adjusting component 54 and connected to the lifting column 51. Under the action of the lifting column 51, the movable panel 52 moves up and down, thereby causing the measuring component 53, adjusting component 54, collecting component 55, and limiting plate 56 to move up and down, changing the detection depth. At the same time, driven by the measuring component 53, the drainage component 43 slides in the sliding groove 421 and moves accordingly, while also causing the filter screen 422 to slide, fitting against the inlet of the drainage channel 432 to filter the water in the soil layer. When no detection is being performed, the water in the soil layer flows through the adjusting component 54 and the filter screen 422 to the lower soil layer of the monitoring device 5 through the drainage channel 432. When detection is being performed, the adjusting component 54 rotates and disengages from the collecting component 55, and the water in the soil layer flows through the adjusting component 54 into the collecting component 55, where it is detected by the measuring component 53 and then discharged.

[0066] In this embodiment, the structure of the inner wall of the movable panel 52 is the same as the structure of the inner wall of the supporting panel 42. That is to say, when no detection is being performed, each level of the monitoring device 5 can drain water through the drainage component 43 to maintain normal water penetration in the soil layer.

[0067] In this embodiment, the top of the measuring component 53 is provided with an inclined surface 531 connected to the top of the movable panel 52, and the bottom is provided with a discharge valve 532. Under the action of the inclined surface 531, the moisture in the soil layer corresponding to the monitoring device 5 is guided to facilitate the division of the detection area, and after the detection is completed, the moisture collected in the measuring component 53 is discharged in a timely manner through the discharge valve 532.

[0068] In this embodiment, the adjustment component 54 includes:

[0069] Two hydraulic shafts 541 are symmetrically distributed and located at both ends of the movable panel 52, inside the movable panel 52.

[0070] The telescopic link 542 is rotatably mounted on the top of the measuring assembly 53 and is rotatably connected to the extended end of the hydraulic shaft 541;

[0071] The rotating shaft 543 is rotatably mounted on the side of the measuring component 53 via a fixing member, and its two ends are fixedly connected to the telescopic connecting rod 542;

[0072] The seepage surface 544 is fixed on one side to the rotating shaft 543, and the other side corresponds to the upper part of the drainage channel 432 and is located below the filter screen surface 422. The seepage surface 544 is provided with multiple seepage holes. When no detection is performed, the seepage surface 544 is in contact with the collection component 55. Under the restriction of the collection component 55, the seepage holes are closed, and water flows into the drainage component 43 through the filter screen surface 422. When water leakage detection is performed, the extended end of the hydraulic shaft 541 retracts, driving the telescopic connecting rod 542 to rotate and retract. This, in turn, drives the seepage surface 544 to rotate upward through the rotating shaft 543. At the same time, the seepage surface 544 separates from the collection component 55, and its side is in contact with the inner wall of the drainage component 43, sealing the drainage component 43. Soil water enters the collection component 55 through the seepage holes and is detected by the measuring component 53.

[0073] In this embodiment, the collection component 55 includes:

[0074] The sealing surface 551 is fixed on the measuring component 53 and corresponds to the seepage surface 544. A connection channel is provided at the junction of the sealing surface 551 and the seepage surface 544.

[0075] The toughness guide surface 552 passes through the connecting channel, with one end set inside the measuring component 53 and the other end fixed to the bottom of the seepage surface 544;

[0076] The collection chamber 553 is located within the measuring component 53. That is, when no detection is being performed, the seepage surface 544 is in contact with the sealing surface 551, and the flexible guiding surface 552 seals the connection channel on the sealing surface 551. During water leakage detection, the seepage surface 544 detaches from the sealing surface 551, and simultaneously pulls out the flexible guiding surface 552, opening the connection channel. Water then flows downward through the seepage hole, through the connection channel, and guided by the flexible guiding surface 552, enters the collection chamber 553. After collection is completed within a predetermined time, the water is transferred to the measuring component 53 for detection and recording.

[0077] In practice, the lifting column 51 first moves the monitoring devices 5 at each level to adjust their depth, ensuring that the adjusting component 54 and the collecting component 55 are in contact. Then, the entire monitoring equipment is placed inside the test soil layer 1, and water is injected from the surface. As the water permeates the soil, it gradually disperses and permeates through the multi-level monitoring devices 5. The water passes through the monitoring devices 5 via the drainage channels 432, seeps directly into the middle, and passes through the monitoring equipment via the inner guide column 6. When monitoring water leakage, the extended end of the hydraulic shaft 541 is retracted, causing the telescopic connecting rod 542 to rotate. The hydraulic system contracts, causing the seepage surface 544 to rotate upward via the rotating shaft 543. The seepage surface 544 disengages from the sealing surface 551, simultaneously pulling out the toughness guide surface 552, opening the connecting channel. Water then flows downward through the seepage hole, passing through the connecting channel and guided by the toughness guide surface 552, into the collection chamber 553. After collection is completed within a predetermined time, the hydraulic shaft 541 resets, causing the seepage surface 544 to reset and sealing the seepage hole. The collected water is then transferred to the measuring component 53 for detection and recording. After recording, the water is discharged through the discharge valve 532 for the next test.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
