Description

Technical Field

[0001] The present invention relates to the technical field of soil carbon flux monitoring, and particularly relates to a soil carbon flux monitoring device based on the Internet of Things. Background Art

[0002] Soil carbon flux refers to the release or absorption rate of carbon elements in the soil, which mainly comes from the carbon dioxide released during soil respiration. In order to study and analyze soil carbon flux, by using a monitoring device based on the Internet of Things, the carbon cycle situation in the soil in different regions can be remotely and real-time understood, reducing the workload of manual monitoring in different regions. When the existing monitoring device monitors soil carbon flux, one end of the monitoring device needs to be inserted into the soil at different depths for monitoring. However, for some areas where the soil is relatively moist, water will seep into the surrounding area of the monitoring probe when it is inserted into the soil, causing the monitoring probe to be immersed in water for a long time, affecting the detection of the carbon dioxide concentration in the soil, and thus affecting the monitoring of soil carbon flux. Therefore, the present invention improves to reduce the influence of soil water seepage on the monitoring device. Summary of the Invention

At the same time, the gas sensitive resistor is located above the gas inner cavity and can monitor the carbon dioxide concentration collected in the gas inner cavity. After the gas sensitive resistor detects different concentrations of carbon dioxide, the resistivity changes, thereby detecting the carbon dioxide concentration at different depths in the soil. The structure of the gas sensitive resistor is relatively simple, easy to install, small in volume, convenient to install and use in different devices. At the same time, the gas sensitive resistor has strong anti-interference ability and can work normally under complex soil environmental conditions. The gas sensitive resistor has good stability and can maintain a high measurement accuracy during long-term use in the soil. The response speed of the gas sensitive resistor is very fast, very sensitive to changes in carbon dioxide concentration, can quickly and accurately detect changes in gas concentration, and complete the monitoring of carbon dioxide concentration in a short time, thereby ensuring the accuracy of soil carbon flux.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 8 :

[0034] Embodiment 1: The present invention provides a soil carbon flux monitoring device based on the Internet of Things, including: a fixed bracket 1, a fixed cone is installed at the bottom of the fixed bracket 1, a sealing cover plate 101 is installed at the top of the fixed bracket 1, and a positioning vertical rod 102 is installed at the top rear of the fixed bracket 1; an installation groove 103 is provided on the outer side of the positioning vertical rod 102; the installation groove 103 is of an annular structure, and the installation end of a diversion cover 104 is installed inside the installation groove 103; the diversion cover 104 is of a conical structure, and a fixing bolt is installed on the installation end of the diversion cover 104; a servo motor is installed on the top of the sealing cover plate 101, a gear is installed at the output end of the servo motor, and a driving wheel 105 is rotatably installed on the top of the sealing cover plate 101; a driving handle is installed at one end of the driving wheel 105; a water pump is also installed on the top of the sealing cover plate 101, and a drain pipe 106 is installed at the output end of the water pump.

[0035] In the embodiment of the present disclosure, when monitoring the soil carbon flux, the fixed bracket 1 is placed on the soil, and the fixed cone at the bottom of the fixed bracket 1 is inserted into the soil for fixation. A distribution box can be installed on the positioning vertical rod 102 at the top rear of the fixed bracket 1 for controlling power supply and other aspects. The sealing cover plate 101 is installed on the top of the fixed bracket 1, and the monitoring end of the monitoring device is inserted into a pre-drilled hole. Then, the sealing cover plate 101 seals the top of the opening to reduce the entry of carbon dioxide in the air into the hole and affect the detection of soil carbon flux. Rotating the driving handle at the side end of the driving wheel 105 on the sealing cover plate 101 can drive the monitoring tube 2 to move up and down. The water pump on the sealing cover plate 101 pumps the seepage water in the soil and discharges it through the drain pipe 106. After the monitoring device is installed on the ground, rotate the installation end of the diversion cover 104 inside the installation groove 103, so that the diversion cover 104 is above the fixed bracket 1 to divert rainwater on rainy days and reduce the rainwater from pouring into the position where the monitoring device is located.

[0036] Example 2. On the basis of Example 1, a monitoring tube 2 is slidably installed at the middle position of the top of the plugging cover plate 101; the bottom of the monitoring tube 2 is of an arc-shaped structure, and a plurality of diversion holes 201 are evenly arranged on the outer side surface of the monitoring tube 2, wherein the diversion holes 201 are of an inclined structure; positioning side holes 202 are also equidistantly arranged on the outer side surface of the monitoring tube 2, and a driving plate 203 is further installed on the outer side of the monitoring tube 2; the outer side of the driving plate 203 is meshed and connected with the outer side of the driving wheel 105; a diversion tube 204 is installed on the outer side of the monitoring tube 2; the top of the diversion tube 204 is connected with the input end of the water pump at the top of the plugging cover plate 101; a plurality of gas inner cavities 205 are arranged inside the monitoring tube 2; partition plates are arranged between the plurality of gas inner cavities 205, and a gas sensitive resistor 206 is installed at the top of the gas inner cavity 205; a rotating driving rod 207 is rotatably installed inside the monitoring tube 2; a gear is installed at the top of the rotating driving rod 207, and the gear at the top of the rotating driving rod 207 is meshed and connected with the gear at the output end of the servo motor at the top of the plugging cover plate 101; a movable plate 208 is installed on the outer side of the rotating driving rod 207; the outer side of the movable plate 208 is connected with the side end of a support plate 209 through a rotating shaft; the other end of the support plate 209 is rotatably connected with a central plate 2010 through a rotating shaft; a plug rod 2011 is installed on the side surface of the central plate 2010; the plug rod 2011 is slidably installed inside the positioning side hole 202, the outer end of the plug rod 2011 is of a conical structure, and a pressure sensor and a temperature sensor are installed on the outer side of the plug rod 2011; a water storage member 2012 is installed at the bottom of the gas inner cavity 205;The water storage member 2012 is of a hemispherical structure, and the bottom of the water storage member 2012 is connected to the side end of the diversion pipe 204. When monitoring the soil carbon flux, the monitoring pipe 2 is installed at the middle position of the plugging cover plate 101. Rotate the driving wheel 105 so that its outer side meshes with and drives the driving plate 203. Then the driving plate 203 drives the monitoring pipe 2 to move downward at the middle position of the plugging cover plate 101, so that the monitoring pipe 2 is inserted into the pre-drilled hole. When the monitoring pipe 2 moves downward, since the diversion holes 201 on its outer side are of an inclined structure, the soil in the hole will not block the diversion holes 201. After the monitoring pipe 2 moves downward, it drives the gear at the top of the rotary driving rod 207 to mesh with the gear at the output end of the servo motor on the top of the plugging cover plate 101. The servo motor rotates to drive the rotary driving rod 207 to rotate inside the monitoring pipe 2. The rotary driving rod 207 drives the movable plate 208 on the outside to move. The two movable plates 208 in the same gas inner cavity 205 approach each other. Then the movable plate 208 drives the concentrating plate 2010 to move through the support plate 209. The concentrating plate 2010 drives the insertion rod 2011 to be inserted into the soil through the positioning side hole 202. The outer end of the insertion rod 2011 is of a conical structure to reduce the resistance to insertion into the soil. The insertion rod 2011 drives the temperature sensor and the pressure sensor to monitor the temperature and pressure of the soil at the same height as the gas inner cavity 205. Then the carbon dioxide in the soil gathers inside the gas inner cavity 205. The carbon dioxide concentration is detected by the gas sensitive resistor 206 at the top of the gas inner cavity 205. For carbon dioxide of different concentrations, the resistivity of the gas sensitive resistor 206 is different. The gas sensitive resistor 206 has a fast response and a long monitoring life, and can accurately detect the soil carbon flux. When water seepage occurs in the gas inner cavity 205, the water storage member 2012 collects the water seepage, and the water pump on the top of the plugging cover plate 101 works to pump out the water seepage collected in the water storage member 2012 through the diversion pipe 204, reducing the influence of the water seepage on the gas sensitive resistor 206.;

When monitoring the soil carbon flux, the photovoltaic panel 301 on the protective housing 3 can generate electricity to provide a power supply for the monitoring device, and the Internet of Things antenna 305 on the inner side of the protective housing 3 can perform remote transmission with the detection center through the Internet of Things technology, so that the soil carbon flux data in the monitored soil is transmitted to the detection center for analysis. In windy weather, the wind flow blows the fan blade on the outer side of the rotating member 303 and rotates along the limiting groove 302, the top of the outer side of the rotating member 303 drives the guide plate 304 to rotate, and the guide plate 304 drives the cleaning plate 306 to move on the outer side of the protective housing 3. The upper and lower positioning plates 307 are installed on the top and the bottom of the protective housing 3, and under the drive of the spring in the sliding groove on the top of the guide plate 304, the brush on the inner side of the cleaning plate 306 cleans the sundries adhered to the outer side of the protective housing 3, preventing the wind flow from driving plastic bags or other sundries to adhere to the protective housing 3 and affecting the normal signal transmission of the Internet of Things antenna 305, and ensuring the normal operation of the Internet of Things technology.

A distribution box is installed on the positioning vertical rod 102 to control aspects such as power supply. The monitoring pipe 2 is installed at the middle position of the sealing cover plate 101.

After the monitoring pipe 2 moves downward, the gear at the top of the rotating driving rod 207 drives the gear at the output end of the servo motor at the top of the sealing cover plate 101 to engage. The servo motor drives the rotating driving rod 207 to rotate inside the monitoring pipe 2, and the rotating driving rod 207 drives the movable plate 208 on the outside to move. The two movable plates 208 in the same gas inner cavity 205 drive the concentrating plate 2010 to move through the supporting plate 209. The concentrating plate 2010 drives the insertion rod 2011 to be inserted into the soil through the positioning side hole 202. The temperature sensor and pressure sensor on the insertion rod 2011 monitor the temperature and pressure of the soil at the same height as the gas inner cavity 205. The carbon dioxide in the soil is collected in the gas inner cavity 205, and the gas sensitive resistor 206 detects the carbon dioxide concentration. The resistivity of the gas sensitive resistor 206 is different for different concentrations of carbon dioxide. When water seeps into the gas inner cavity 205, the water storage member 2012 collects the seepage water, and the water pump at the top of the sealing cover plate 101 works to extract and discharge the seepage water collected in the water storage member 2012 through the diversion pipe 204.
