Description

Technical Field

[0001] This invention relates to the field of soil carbon sequestration monitoring, specifically a soil carbon sequestration capacity monitoring device. Background Technology

[0002] Soil carbon sequestration refers to the natural or artificial processes by which soil absorbs and stores atmospheric carbon dioxide through biological, chemical, and physical processes, fixing it in the soil over a long period. Typically, soil health analysis is obtained by manually collecting soil samples from various accessible areas to represent different soil regions. This method is time-consuming and labor-intensive, cannot be monitored online in real time, and while it provides overall analytical data on carbon dioxide absorption in the soil, it lacks in-depth understanding of the carbon dioxide content distribution at different locations within soil cross-sections. Furthermore, the diverse gas composition in soil further complicates precise soil monitoring. Therefore, this paper proposes a soil carbon sequestration capacity monitoring device to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a soil carbon sequestration capacity monitoring device in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solution: a soil carbon sequestration capacity monitoring device, including a soil monitoring plate, a sensor device, and a wireless transmission antenna for data transmission with a soil health analysis platform. The surface of the soil monitoring plate is provided with a plurality of circular holes, and a central circular block is connected to the center of each circular hole. One end of the central circular block is provided with a column groove, and the inside of the column groove is connected to the other end of the central circular block through a plug hole. One of the detection probes connected to the sensor device is located in the middle of the column groove. The groove opening is sealed with a round cover, and a carbon dioxide capturing membrane is installed inside the hole structure in the middle of the round cover. An alkaline solid container is sealed to the insertion hole, and the alkaline solid container is filled with alkaline solid. The detection probe is located between the carbon dioxide capturing membrane and the insertion hole.

[0005] Preferably, the carbon dioxide capture membrane is one of a polymer membrane and a porous inorganic membrane.

[0006] Preferably, two perforated plates are symmetrically installed inside the column groove, and one end of a guide rod is fixed inside the holes of both perforated plates. The two guide rods slide in contact with the guide holes located on the electromagnet module, and the other end of the guide rod contacts the inner wall of the column groove. A spring is fitted on the guide rod.

[0007] Preferably, an annular magnet is installed on the circular wall inside the column groove, and the annular magnet is magnetically attracted to the electromagnet module to form a sealed cover for the insertion hole.

[0008] Preferably, the upper and lower ends of one side of the soil monitoring insert plate are fixedly connected to the two ends of the same centralized connecting plate by bolts, and the connecting pipe connected at the top of the soil monitoring insert plate is equipped with a flange, and the flange is fixedly connected to the bottom of the riser by a circular plate with bolts distributed at the bottom.

[0009] Preferably, equipment connection seats are provided on both sides of the top of the riser. One equipment connection seat is fixedly connected to the sensor device, and the other equipment connection seat is equipped with a support frame, on which a solar panel is installed.

[0010] Preferably, the riser has a wire harness inside, and the top of the riser is fixedly connected to the wireless transmission antenna.

[0011] Preferably, the detection probe and the sensor device are connected by a wiring harness, and the signal output terminal of the sensor device is connected to a wireless transmission antenna.

[0012] Preferably, the sensor device consists of a plurality of carbon dioxide sensors, and each carbon dioxide sensor is matched with a detection probe.

[0013] The beneficial effects of this invention are: 1. By using a matrix of circular holes on a soil monitoring plate and the detection probes positioned at those holes, and dividing the soil cross-section into multiple hierarchical regions based on at least one row of detection probes from top to bottom, it is beneficial to monitor the distribution of carbon dioxide content in the collected soil cross-section layers. Second, by utilizing the selective permeation of carbon dioxide gas through the carbon dioxide capture membrane, the amount of non-carbon dioxide gas entering the column groove is greatly reduced, ensuring the accuracy of the detection probe in detecting the carbon dioxide content in the soil. Third, by using the alkaline solid inside the alkaline solid container, and combining the characteristic of alkaline solid to easily absorb carbon dioxide, carbon dioxide in the soil can be facilitated to pass through the carbon dioxide capture membrane into the column groove. This can both accelerate the entry of carbon dioxide from the soil into the column groove and absorb the detected carbon dioxide, so that the amount of carbon dioxide can be calculated and analyzed based on the weight change after the alkaline solid reaction. Fourth, by using a ring magnet to magnetically attract the iron core of the electromagnet module, one side of the electromagnet module is sealed and covered at the insertion hole, achieving the effect of sealing the port of the alkaline solid container and preventing the alkaline solid inside the container from being affected by carbon dioxide from non-soil sources.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0020] Please see Figure 1-7 As shown, a soil carbon sequestration capacity monitoring device includes a soil monitoring plate 1, a sensor device 5, and a wireless transmission antenna 7 for transmitting data with a soil health analysis platform. The surface of the soil monitoring plate 1 is provided with a plurality of circular holes 110, and a central circular block 120 is connected to the center of each circular hole 110. One end of the central circular block 120 is provided with a column groove 121, and the inside of the column groove 121 is connected to the other end of the central circular block 120 through a plug hole 122. One of the detection probes 510 connected to the sensor device 5 is located in the middle of the column groove 121. The groove 121 is sealed with a round cover 12, and a carbon dioxide capturing membrane 11 is installed inside the hole structure in the middle of the round cover 12. An alkaline solid container 130 is sealed to the insertion hole 122, and the alkaline solid container 130 is filled with alkaline solid. The detection probe 510 is located between the carbon dioxide capturing membrane 11 and the insertion hole 122.

[0021] like Figure 6 As shown, the carbon dioxide capture membrane 11 is one of a polymer membrane and a porous inorganic membrane, so that carbon dioxide gas in the soil can be selectively passed through the carbon dioxide capture membrane 11 into the interior of the column groove 121, and can be detected by the detection probe 510.

[0022] like Figure 5 and Figure 7 As shown, two perforated plates 9 are symmetrically installed inside the column groove 121, and one end of a guide rod 14 is fixed inside the holes of both perforated plates 9. The two guide rods 14 slide in contact with the guide holes 13a on the electromagnet module 13, and the other end of the guide rod 14 contacts the inner wall of the column groove 121. A spring 15 is fitted on the guide rod 14. A ring magnet 10 is installed on the circular wall inside the column groove 121, and the ring magnet 10 is magnetically attracted to the electromagnet module 13 to form a sealing cover for the insertion hole 122. Specific solution: If the electromagnet module 13 is not powered, the ring magnet 10 magnetically attracts the iron core of the electromagnet module 13, so that one side of the electromagnet module 13 seals and covers the insertion hole 122, thereby achieving the effect of sealing the port of the alkaline solid container 130 and preventing the alkaline solid inside the alkaline solid container 130 from being affected by carbon dioxide in non-soil. When the soil monitoring plate 1 is inserted into the soil, the electromagnet module 13 is energized to form a magnetic pole opposite to that of the ring magnet 10. This causes the electromagnet module 13 to release the seal on the port of the alkaline solid container 130 under the mutual repulsion of like magnetic attraction. Based on the fact that quicklime in alkaline solids is commonly used in drying tubes and has both absorption and drying functions, and easily absorbs carbon dioxide, it can facilitate the smooth passage of carbon dioxide in the soil through the carbon dioxide capture membrane 11 into the interior of the column groove 121.

[0023] Combination Figure 2 As shown, the upper and lower ends of one side of the soil monitoring insert plate 1 are fixedly connected to the two ends of the same centralized connecting plate 8 by bolts. The connecting pipe 2 connected to the top of the soil monitoring insert plate 1 is equipped with a flange 210. The flange 210 is fixedly connected to the bottom of the riser 3 by a circular plate 310 with bolts distributed at the bottom. Through the riser 3, the relevant monitoring equipment can be placed at a high place to avoid damage from external organisms.

[0024] like Figure 1 As shown, both sides of the top of the riser 3 are provided with equipment connection seats 320. One equipment connection seat 320 is fixedly connected to the sensor device 5, and the other equipment connection seat 320 is equipped with a support frame 610. A solar panel 6 is installed on the support frame 610. The solar panel 6 can provide power for the operation of the sensor device 5 and the wireless transmission antenna 7.

[0025] Furthermore, the riser 3 is equipped with a wire harness 4 inside, and the top of the riser 3 is fixedly connected to the wireless transmission antenna 7.

[0026] Furthermore, the detection probe 510 is connected to the sensor device 5 via a wiring harness 4, and the signal output terminal of the sensor device 5 is connected to the wireless transmission antenna 7.

[0027] Furthermore, the sensor device 5 consists of several carbon dioxide sensors, and each carbon dioxide sensor is matched with a detection probe 510.

[0028] Working principle: When the soil monitoring insert plate 1 is inserted into the soil of the monitoring area, the electromagnet module 13 is energized to form a magnetic pole opposite to that of the ring magnet 10. Under mutual repulsion, the surface of one side of the electromagnet module 13 leaves the inner port of the insertion hole 122, thereby releasing the seal on the port of the alkaline solid container 130 located inside the insertion hole 122. Based on the characteristics of soda lime, which is commonly used in drying tubes and has both absorption and drying functions, and easily absorbs carbon dioxide, it can facilitate the smooth passage of carbon dioxide in the soil through the carbon dioxide capture membrane 11 into the column groove 121. At the same time, the detection probe 510 located in the middle of the column groove 121 detects carbon dioxide and generates a signal, which is transmitted to the sensor device 5 via the wire harness 4. The sensor device 5 processes all the received signals and transmits them to the soil health analysis platform via the wireless transmission antenna 7, thus completing the data collection and transmission of soil carbon sink monitoring.

[0029] The difference in this invention is: 1. By using a number of circular holes 110 arranged in a matrix on the soil monitoring plate 1 and the detection probes 510 arranged at the circular holes 110, and taking at least one row of detection probes 510 from top to bottom as a reference to divide the soil cross section into multiple layered areas for detection, it is beneficial to monitor the distribution of carbon dioxide content in the collected soil cross section layer. Second, by utilizing the selective permeation of carbon dioxide gas through the carbon dioxide capture membrane 11, the amount of non-carbon dioxide gas entering the column groove 121 is greatly reduced, ensuring the accuracy of the detection probe 510 in detecting the carbon dioxide content in the soil. Third, by using the alkaline solid set inside the alkaline solid container 130, and combining the characteristic that the alkaline solid easily absorbs carbon dioxide, it can facilitate the smooth passage of carbon dioxide in the soil through the carbon dioxide capture membrane 11 into the column trough 121. This can both accelerate the entry of carbon dioxide in the soil into the column trough 121 and absorb the detected carbon dioxide, so that the amount of carbon dioxide can be calculated and analyzed based on the weight change after the alkaline solid reaction. Fourth, by using the ring magnet 10 to magnetically attract the iron core of the electromagnet module 13, one side of the electromagnet module 13 is sealed and covered at the insertion hole 122, thereby achieving the effect of sealing the port of the alkaline solid container 130 and preventing the alkaline solid inside the alkaline solid container 130 from being affected by carbon dioxide in non-soil environments.
