Description

Technical Field

[0001] This invention relates to the field of gas detection technology, specifically to a respiration monitoring device for self-stabilizing soil on tropical forest slopes. Background Technology

[0002] The Tropical Forest Slope Self-Stabilizing Soil Respiration Monitoring Device is a soil respiration monitoring device specifically designed for tropical forest slope environments. It can accurately measure the exchange rate of gases such as carbon dioxide between the soil and the atmosphere, thereby assessing the intensity of soil respiration.

[0003] Existing technologies, such as the SRS-2000 T portable soil respiration meter, involve the operator first inserting a stainless steel blade into the soil to be tested. Then, the concentrations of CO2 and H2O in the respiration chamber are programmed to simulate different environmental gradients. Finally, the gas changes in the respiration chamber are monitored in real time by its built-in high-precision miniature CO2 infrared gas analyzer, thus completing the soil respiration monitoring operation.

[0004] While the aforementioned measuring instrument can monitor soil respiration, its installation relies solely on workers pressing a stainless steel knife into the soil for fixation. However, on sloping terrain, the respiration chamber may tilt or shift due to gravity or external forces, affecting measurement accuracy. Therefore, it is necessary to develop a self-stabilizing soil respiration monitoring device for tropical forest slopes that can adapt to sloping terrain and simultaneously improve the stability of the monitoring device on slopes. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a self-stabilizing soil respiration monitoring device for tropical forest slopes. After the insertion cone and stabilizing cylinder are inserted deep into the soil layer, a stabilizing component is used to fix the stabilizing cylinder and insertion cone a second time, thereby improving the fixation effect of the stabilizing cylinder and insertion cone inside the soil and reducing the possibility of the monitoring device tilting under gravity or external forces.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a self-stabilizing soil respiration monitoring device for tropical forest slopes, comprising a controller, an analyzer, and a monitoring cylinder. A cover plate is detachably connected to the monitoring cylinder, and a support frame is fixedly connected to the lower part of the inner side wall of the monitoring cylinder. A telescopic component and a stabilizing cylinder are fixedly connected to the bottom of the support frame. The telescopic component is located inside the stabilizing cylinder, and the controller is used to control the extension and retraction of the output shaft of the telescopic component.

[0007] The bottom of the stabilizing cylinder is fixedly connected to an internally hollow insertion cone. A fixed plate is fixedly connected to the inner side wall of the stabilizing cylinder. A transmission disc is installed inside the insertion cone. The output shaft of the telescopic component extends through the fixed plate into the insertion cone and is fixedly connected to the top of the transmission disc. A hinge rod is hinged to the bottom circumferentially of the fixed plate. A hinge frame is hinged to the end of the hinge rod away from the fixed plate. The hinge frame is hinged to the side wall of the transmission disc. A stabilizing component is installed on the hinge frame to improve the stability of the stabilizing cylinder inside the soil. An adaptation component is installed inside the stabilizing cylinder to adapt the monitoring cylinder to the terrain.

[0008] The monitoring cylinder is equipped with a monitoring component for real-time monitoring of the internal temperature, humidity, and carbon dioxide concentration.

[0009] The technical principles of the above solution are as follows:

[0010] Workers removed the cover plate from the top of the monitoring cylinder and inserted the lower part of the stabilizing cylinder and the monitoring cylinder into the soil layer using the insertion cone. Then, the analyzer was placed on the upper part of the monitoring cylinder to measure the soil condition. At the same time, the controller controlled the extension of the output shaft of the telescopic component, which drove the transmission plate to move downward. The transmission plate drove the hinge frame to swing under the limit of the hinge rod. The hinge frame drove the stabilizing component to operate, which then fixed the insertion cone and the stabilizing cylinder a second time.

[0011] During this process, the output shaft of the telescopic component also drives the adaptation component to operate, which adapts the monitoring tube to the terrain and reduces the exchange of gas inside the monitoring tube with the outside gas.

[0012] After the fixing and adaptation operations are completed, the controller controls the operation of the monitoring component to perform real-time auxiliary monitoring of soil respiration, so that it can work with the analyzer to monitor soil respiration.

[0013] The above approach has the following beneficial effects:

[0014] 1. After the insertion cone and stabilizing cylinder are inserted into the soil, the present invention can fix the stabilizing cylinder and insertion cone a second time through the stabilizing component, thereby improving the fixing effect of the stabilizing cylinder and insertion cone inside the soil and reducing the possibility of the monitoring device tilting under gravity or when subjected to external forces.

[0015] 2. The design of the adapter component in this invention enables it to support the monitoring tube during operation and fill the gap between the outer wall of the monitoring tube and the soil surface, so that the inside of the monitoring tube remains sealed, thereby reducing the possibility of carbon dioxide leakage or infiltration of outside air and improving the accuracy of concentration measurement.

[0016] 3. By fixing the insertion cone and the stabilizing cylinder together, the present invention allows workers to directly insert the stabilizing cylinder into the soil layer through the insertion cone when inserting the stabilizing cylinder into the soil layer, thus completing the initial fixation of the stabilizing cylinder and the insertion cone. Moreover, this process causes less disturbance to the soil layer, which reduces its impact on subsequent monitoring results and improves the authenticity of the monitoring results.

[0017] Furthermore, the stabilizing component includes a connecting rod hinged to the end of the hinge frame away from the transmission disk, a stabilizing rod hinged to the end of the connecting rod away from the hinge frame, and a stabilizing hole circumferentially opened along the side wall of the insertion cone, with the stabilizing rod located in the adjacent stabilizing hole and slidingly engaged with the inner side wall of the stabilizing hole.

[0018] Beneficial effects: When the transmission disc is driven downward by the output shaft of the telescopic component, it can decompose the downward pressure into the sliding force of each stabilizing rod, causing it to slide towards the soil layer outside the insertion cone. At this time, the soil's wrapping force on the stabilizing rod can form pull-out resistance. Thus, when the monitoring cylinder is subjected to external force, the device can reduce the possibility of the monitoring cylinder tilting under the influence of pull-out resistance.

[0019] Furthermore, the adapter component includes an air box fixedly connected to the inner wall of the stabilizing cylinder, an output shaft of the telescopic component extending through the air box to the bottom of the air box and vertically sliding with the top and bottom walls of the air box, and an air plate fixedly connected to the output shaft of the telescopic component inside the air box, the air plate sliding vertically with the inner wall of the air box.

[0020] The side wall of the inflation box is connected to several one-way valves for air intake, and the stabilizing cylinder has several air inlets. All air inlets are located on the same straight line as the adjacent one-way valves. The inflation box is connected to an air outlet pipe, and an air outlet one-way valve is connected to the connection between the air outlet pipe and the inflation box. An air bladder is fixedly connected to the outer wall of the monitoring cylinder, and the end of the air outlet pipe away from the air outlet one-way valve passes through the side wall of the monitoring cylinder and connects to the air bladder.

[0021] Beneficial effects: When the monitoring device is deployed on a slope, the extension of the telescopic output shaft can push the inflation plate downwards, allowing gas from the inflation chamber to enter the air bladder through the one-way valve and outlet pipe, causing it to inflate and expand. This creates a supporting force opposite to the slope's inclination, thus automatically adjusting the monitoring cylinder's angle. Simultaneously, after the air bladder inflates, it fills the gap between the outer wall of the monitoring cylinder and the soil surface, reducing gas exchange between the inside of the cylinder and the outside environment, thereby improving the accuracy of soil respiration monitoring.

[0022] Furthermore, the monitoring components include a temperature and humidity sensor and a carbon dioxide concentration sensor fixedly connected to the inner wall of the monitoring cylinder. The controller is electrically connected to a staff terminal. The controller is used to receive the temperature and humidity signals collected by the temperature and humidity sensor and the carbon dioxide concentration signal collected by the carbon dioxide concentration sensor in real time, and send the temperature and humidity signals and carbon dioxide concentration signals to the staff terminal.

[0023] Beneficial effects: By coordinating temperature and humidity sensors with carbon dioxide concentration sensors, real-time data on the microenvironment within the monitoring tube can be acquired. When soil temperature rises, leading to increased microbial activity, the release rate of carbon dioxide increases. Simultaneously, the accelerated diffusion of gas under high temperatures may result in lower measured values. In this case, dynamic correction of carbon dioxide concentration using temperature and humidity data can reduce the calculation error of respiratory flux, thereby improving monitoring accuracy.

[0024] Furthermore, the stabilizing cylinder is also equipped with a reset assembly for resetting the stabilizing cylinder when it shifts. The reset assembly includes a reset frame fixedly connected inside the stabilizing cylinder. The reset frame has several sliding grooves, each of which is laterally fitted with a permanent magnet. Electromagnets are fixedly connected to both ends of the sliding grooves. Several tilt sensors are fixedly connected to the bottom of the reset frame. The controller is used to receive the tilt signals collected by the tilt sensors in real time and control the energizing intensity of the electromagnets based on the tilt signals.

[0025] Beneficial effects: The tilt sensor can monitor the offset of the stabilizing cylinder in real time, organize it into a tilt signal and send it to the controller. The controller dynamically adjusts the energizing intensity of the electromagnet according to the tilt signal, so as to generate a magnetic gradient opposite to the offset direction, so that the permanent magnet slides laterally along the slide under the action of magnetic force, thereby achieving precise compensation for the offset.

[0026] Furthermore, the monitoring cylinder is also equipped with an alarm component for emitting audible and visual alarms. The alarm component includes an alarm light and a speaker fixedly connected to the outer wall of the monitoring cylinder. The controller is used to control the opening and closing of the alarm light and speaker based on the tilt angle signal sent by the tilt angle sensor.

[0027] Beneficial effects: When staff set a tilt threshold, and the tilt signal detected by the tilt sensor exceeds the tilt threshold, the controller activates the alarm light and speaker to provide an audible and visual alarm. This allows the device to transmit fault information to the staff, enabling them to make timely and targeted adjustments to the device's tilt, thereby improving the stability of the monitoring device and the accuracy of subsequent monitoring.

[0028] Furthermore, the shape of the hinge frame is one of L-shape, V-shape, and arc shape.

[0029] Beneficial effects: By specifically designing the shape of the articulated frame, its bending stiffness can be improved while transmitting directional force, thereby enhancing the operational stability of the monitoring device.

[0030] Furthermore, the end of the stabilizer bar furthest from the connecting rod features a barb design.

[0031] Beneficial effects: When the stabilizer bar extends into the soil layer, its barb design can improve its gripping force on the soil layer, making the pull-out resistance formed by the soil's wrapping force on the stabilizer bar greater when the monitoring tube is subjected to external forces, thereby further reducing the possibility of the monitoring tube tilting.

[0032] Furthermore, a counterweight is fixedly connected to the bottom wall of the inserted cone.

[0033] Beneficial effects: The design of the counterweight lowers the center of gravity of the monitoring device, which reduces the overturning moment caused by the high center of gravity, thereby further reducing the possibility of the monitoring device tilting.

[0034] Furthermore, a barrier mesh is fixedly connected to each air intake.

[0035] Beneficial effects: The barrier net can block soil particles from entering, reducing the possibility of soil particles clogging the air inlet.

[0036] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The following detailed description illustrates the specific implementation method:

[0047] Example 1:

[0048] As attached Figure 1As shown: A self-stabilizing soil respiration monitoring device for tropical forest slopes includes a controller, an analyzer, and a monitoring cylinder 1. A cover plate 2 is detachably attached to the monitoring cylinder 1. A support frame 3 is welded to the lower part of the inner wall of the monitoring cylinder 1. A telescopic component and a stabilizing cylinder 4 are bolted to the bottom of the support frame 3. The telescopic component is located inside the stabilizing cylinder 4. The controller is used to control the extension and retraction of the output shaft of the telescopic component. In this embodiment, an electric telescopic rod 5 is used as the telescopic component, and an LI-8100A analyzer (not shown in the figure) is used as the analyzer.

[0049] like Figure 2 and Figure 4 As shown, the bottom of the stabilizing cylinder 4 has an integrally formed hollow insertion cone 6. A fixing plate 7 is welded to the inner wall of the stabilizing cylinder 4. A transmission disc 8 is provided inside the insertion cone 6. The output shaft of the electric telescopic rod 5 passes through the fixing plate 7 and extends into the insertion cone 6, where it is bolted to the top of the transmission disc 8. A hinge rod 9 is hinged to the fixing plate 7 around its bottom. A hinge frame 10 is hinged to the end of the hinge rod 9 away from the fixing plate 7. The hinge frames 10 are all hinged to the side wall of the transmission disc 8. Each hinge frame 10 is provided with a stabilizing component to improve the stability of the stabilizing cylinder 4 inside the soil. The shape of the hinge frame 10 is one of L-shape, V-shape, and arc shape. In this embodiment, the shape of the hinge frame 10 is L-shaped.

[0050] like Figure 4 As shown, the stabilizing assembly includes a connecting rod 11 hinged to the end of the hinge frame 10 away from the transmission disk 8, and a stabilizing rod 12 hinged to the end of the connecting rod 11 away from the hinge frame 10. The insertion cone 6 has a stabilizing hole circumferentially opened along its side wall, and the stabilizing rod 12 is located in the adjacent stabilizing hole and slides in contact with the inner side wall of the stabilizing hole.

[0051] Specifically, after determining the monitoring location, the staff inserts the lower part of the stabilizing cylinder 4 and the monitoring cylinder 1 into the soil layer using the insertion cone 6. In this embodiment, the insertion depth of the lower part of the monitoring cylinder 1 is 10cm, and the height of the upper part of the monitoring cylinder 1 protruding above the ground is 3cm. Then, the staff removes the cover plate 2 and places the LI-8100A analyzer on top of the monitoring cylinder 1 to measure the soil conditions. Simultaneously, the controller extends the output shaft of the electric telescopic rod 5, causing it to drive the transmission disc 8, which is bolted to it, to move downwards. Since the two ends of the hinge rod 9 are hinged to the bottom of the fixed plate 7 and the hinge frame 10 respectively, and the hinge frame 10 is hinged to the side wall of the transmission disc 8, the downward movement of the transmission disc 8 causes the hinge frame 10 to swing within the limit of the hinge rod 9, causing the end of the hinge frame 10 away from the hinge rod 9 to move away from each other. In this embodiment, the diameter of the monitoring cylinder 1 is 20cm.

[0052] Since the two ends of the connecting rod 11 are hinged to the hinge frame 10 and the stabilizing rod 12 respectively, and the stabilizing rod 12 is located in the adjacent stabilizing hole and slides in contact with the inner side wall of the stabilizing hole, when the hinge frame 10 swings, it can drive the connecting rod 11 hinged to it to swing, and through the connecting rod 11, it can drive the adjacent stabilizing rod 12 to expand towards the soil layer, thereby extending the stabilizing rod 12 into the soil layer, so that the soil layer covers the stabilizing rod 12 and provides pull-out resistance for the stabilizing rod 12.

[0053] The stabilizing cylinder 4 is equipped with an adapter component for adapting the monitoring cylinder 1 to the terrain.

[0054] like Figure 3 As shown, the adapter component includes an air box 13 welded to the inner wall of the stabilizing cylinder 4, an electric telescopic rod 5 output shaft extending through the air box 13 to the bottom of the air box 13 and vertically sliding with the top and bottom walls of the air box 13, and an air plate 14 bolted to the output shaft of the electric telescopic rod 5 located inside the air box 13, the air plate 14 vertically sliding with the inner wall of the air box 13.

[0055] Several one-way air inlets 15 are connected to the side wall of the inflation box 13, and several air inlets are opened on the stabilizing cylinder 4. A barrier mesh (not shown in the figure) is fixedly adhered to each air inlet, and each air inlet is on the same straight line as its adjacent one-way air inlet 15. An air outlet pipe 16 is connected to the inflation box 13, and an air outlet one-way valve 17 is connected to the connection between the air outlet pipe 16 and the inflation box 13. An air bladder 18 is fixedly adhered to the outer wall of the monitoring cylinder 1, and the end of the air outlet pipe 16 away from the air outlet one-way valve 17 passes through the side wall of the monitoring cylinder 1 and connects to the air bladder 18. In this embodiment, the flow direction of the one-way air inlets 15 is unidirectional from the outside of the inflation box 13 to the inside of the inflation box 13, and the flow direction of the one-way air outlet valve 17 is unidirectional from the inside of the inflation box 13 to the outside of the inflation box 13.

[0056] Specifically, when the output shaft of the electric telescopic rod 5 extends, it can drive the inflatable plate 14, which is bolted to it, to slide downward in the inflatable box 13. This allows the gas at the bottom of the inflatable plate 14 to enter the airbag 18 through the one-way valve 17 and the outlet pipe 16, causing the airbag 18 to inflate. The deformation of the airbag 18 adapts to the terrain. At the same time, the airbag 18 also supports the monitoring cylinder 1 and fills the gap between the outer wall of the monitoring cylinder 1 and the soil surface to reduce the escape of gas from the monitoring cylinder 1.

[0057] During this process, when the air-filled plate 14 moves downward, a negative pressure is generated above it, which can draw in external gas through the air intake one-way valve 15, causing the airflow to carry soil particles to gather at the position of the stabilizing cylinder 4, thereby increasing the soil density around the stabilizing cylinder 4 and further improving the stability of the stabilizing cylinder 4 in the soil layer.

[0058] The monitoring cylinder 1 is equipped with a monitoring component for real-time monitoring of the internal temperature, humidity and carbon dioxide concentration of the monitoring cylinder 1.

[0059] like Figure 2 As shown, the monitoring component includes a temperature and humidity sensor 19 and a carbon dioxide concentration sensor 20, which are fixedly connected to the inner wall of the monitoring cylinder 1 with screws. The controller is electrically connected to a staff terminal. The controller is used to receive the temperature and humidity signals collected by the temperature and humidity sensor 19 and the carbon dioxide concentration signals collected by the carbon dioxide concentration sensor 20 in real time, and send the temperature and humidity signals and the carbon dioxide concentration signals to the staff terminal.

[0060] Specifically, after the stabilizing cylinder 4 is inserted into the soil layer, the temperature and humidity sensor 19 and the carbon dioxide concentration sensor 20 collect the soil temperature and humidity and carbon dioxide concentration inside the monitoring cylinder 1, respectively, and integrate them into temperature and humidity signals and carbon dioxide concentration signals. These signals are then sent to the controller, which, upon receiving them, transmits them to the operator's terminal for review. This allows operators to monitor the current operation of the monitoring device in real time and further analyze soil respiration based on the monitored temperature, humidity, and carbon dioxide concentration signals. During this process, operators use the monitored temperature, humidity, and carbon dioxide concentration signals as a basis to assist in interpreting the analysis results of the LI-8100A analyzer, thereby further improving the accuracy of the analysis.

[0061] like Figure 3 and Figure 5 As shown, the stabilizing cylinder 4 is also provided with a reset assembly for resetting the stabilizing cylinder 4 when it shifts. The reset assembly includes a reset frame 21 welded inside the stabilizing cylinder 4. The reset frame 21 has several sliding grooves, and permanent magnets 22 are slidably fitted in each of the sliding grooves. Electromagnets 23 are fixedly bonded to both ends of the sliding grooves. In this embodiment, the electromagnets 23 are all polarized with their adjacent permanent magnets 22. Several tilt sensors 24 are fixedly connected to the bottom of the reset frame 21 by screws. The controller is used to receive the tilt signals collected by the tilt sensors 24 in real time and control the energizing intensity of the electromagnets 23 based on the tilt signals.

[0062] Specifically, since the tilt sensor 24 is located within the groove on the reset frame 21, and the reset frame 21 is located inside the stabilizing cylinder 4, the tilt sensor 24 can monitor the tilt of the stabilizing cylinder 4 in real time. When the stabilizing cylinder 4 shifts within the soil layer, the tilt sensor 24 sends the detected tilt signal to the controller, which then controls the energizing strength of the electromagnet 23 based on the tilt signal. For example, as... Figure 5As shown, when the stabilizing cylinder 4 tilts to the left, since the electromagnets 23 in this embodiment are all polarized with their adjacent permanent magnets 22, and the permanent magnets 22 are all located in their adjacent grooves, and the electromagnets 23 are all located at both ends of their adjacent grooves, the controller controls the electromagnets 23 located on the left side of the groove to be energized and the electromagnets 23 located on the right side of the groove to be de-energized, so that the electromagnets 23 located on the left side of the groove repel the permanent magnets 22 to the right, thereby realizing the reset of the center of gravity of the stabilizing cylinder 4 and reducing the offset angle of the stabilizing cylinder 4.

[0063] The monitoring cylinder 1 is also equipped with an alarm component for emitting audible and visual alarms. The alarm component includes an alarm light 25 and a speaker 26 embedded in the outer wall of the monitoring cylinder 1. The controller is used to control the opening and closing of the alarm light 25 and the speaker 26 based on the tilt angle signal sent by the tilt angle sensor 24.

[0064] Specifically, the operator sets the maximum offset threshold for the stabilizing cylinder 4. When the tilt signal detected by the tilt sensor 24 exceeds the maximum offset threshold, the controller activates the alarm light 25 and broadcasts an alarm voice through the speaker 26. In this embodiment, the controller also simultaneously sends an alarm signal to the operator's terminal, allowing the operator to intuitively understand the operating status of the monitoring device. This reduces the possibility of the monitoring device tilting in a sloping environment, which could affect the final monitoring results. The design of the alarm light 25 and speaker 26 allows the operator to promptly adjust the tilt angle of the monitoring device when it issues an alarm, thereby improving the stability of the monitoring device and ensuring the accuracy of the final monitoring results.

[0065] After the insertion cone 6 and the stabilizing cylinder 4 are inserted into the soil, the present invention uses a stabilizing component to fix the stabilizing cylinder 4 and the insertion cone 6 a second time, which improves the fixing effect of the stabilizing cylinder 4 and the insertion cone 6 inside the soil, thereby reducing the possibility of the monitoring device tilting under gravity or external force.

[0066] Example 2:

[0067] As attached Figure 4 As shown, the difference from Embodiment 1 is that the end of the stabilizer bar 12 away from the connecting bar 11 is designed with a barb.

[0068] Specifically, when the stabilizing rod 12 extends into the soil layer, the soil can cover the stabilizing rod 12. At this time, the barb design of the stabilizing rod 12 can provide it with stable pull-out resistance, so that when the stabilizing cylinder 4 is deflected, it can reduce the amount of deflection under the pull-out resistance of the stabilizing rod 12, thereby improving the stability of the monitoring device and thus improving the accuracy of soil respiration monitoring.

[0069] Example 3:

[0070] As attached Figure 2 As shown, the difference from Embodiment 2 is that the inner bottom wall of the insertion cone 6 is integrally formed with a counterweight block 27.

[0071] Specifically, since the counterweight 27 is located on the bottom wall of the insertion cone 6, it can lower the center of gravity of the entire monitoring device. This reduces the offset of the stabilizing cylinder 4 by lowering the center of gravity of the monitoring device, enabling the monitoring device to perform more accurate monitoring operations when monitoring soil respiration.

[0072] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
