Description

Technical Field

[0001] The present invention relates to the technical field of CO2 concentration monitoring, and in particular to a device for monitoring the CO2 concentration in soil of a forest ecosystem. Background Art

[0002] In recent decades, scientists around the world have been closely focused on the hot topic of source-sink balance, specifically the impact of changes in CO2 concentrations on global warming and the associated consequences. Furthermore, the carbon balance in soils has also garnered considerable attention. Soil carbon not only releases significant amounts of CO2 but also accelerates global warming and other climate changes. Therefore, to monitor CO2 releases and concentrations, comprehensive monitoring and research of soil respiration is crucial. This not only provides a detailed scientific understanding of its absorption and emission processes in nature but also plays a profound role in addressing the harmful effects of global climate change.

[0003] Currently, commonly used methods for monitoring soil CO2 concentrations include the vapor phase capture method and the electrochemical generation sensor method. The vapor phase capture method is a monitoring method based on basic physical principles that can capture and measure the CO2 concentration in gas samples with high precision. This method has the advantages of high sensitivity, high precision, and low error rate, and is currently one of the most commonly used methods for monitoring soil CO2 concentrations. The electrochemical generation sensor method is a monitoring method based on chemical reactions, which calculates the concentration of CO2 by measuring the reaction products in the electrolyte solution. This method has the advantages of simple operation, rapidity, and low cost, but it also has certain errors and limitations.

[0004] When monitoring the carbon dioxide concentration in forest soil, the monitoring equipment is placed on the ground. The forest vegetation is dense, and sunlight has difficulty reaching the ground. This makes it difficult for the monitoring devices used in the forest ecosystem to provide the energy required for operation by converting light energy into electricity like conventional monitoring equipment. As a result, the monitoring devices are unable to regularly transmit monitoring data over a long period of time. Summary of the Invention

[0005] (1) Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a monitoring device for the soil CO2 concentration in a forest ecosystem, which solves the technical problem that the forest vegetation is dense and sunlight is difficult to reach the ground, making it difficult for monitoring devices used in the forest ecosystem to provide the energy required for work by converting light energy into electrical energy like conventional monitoring equipment, resulting in the monitoring device being unable to regularly transmit monitoring data over a long period of time.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] An embodiment of the present invention provides a device for monitoring the CO2 concentration in the soil of a forest ecosystem, comprising a transport trolley that moves along the ground, a drilling assembly arranged at the side end of the transport trolley and drilling holes in the ground as it moves, a plurality of monitoring assemblies housed inside the transport trolley and sequentially placed at the drilling positions of the drilling assembly as the transport trolley moves, and a power supply assembly arranged on the top of the transport trolley, wherein the power supply assembly converts light energy into electrical energy and provides electrical energy for the movement of the transport trolley and the operation of the monitoring assembly. The monitoring assembly comprises a monitoring tube coaxially supported and fixed to the upper end of the ground, a monitoring column vertically slidably housed in the monitoring tube and inserted into a hole drilled in the ground, and a plurality of circles of monitoring units evenly spaced along the length direction of the monitoring column, wherein each circle of the monitoring units comprises a plurality of monitoring units evenly spaced circumferentially at the circumferential side ends of the monitoring column.

[0010] A monitoring device for soil CO2 concentration in a forest ecosystem is proposed in an embodiment of the present invention. When the monitoring device is used to monitor the soil CO2 concentration in a forest ecosystem, a transport cart is used to move in the forest, and a drilling assembly is used to drill a hole in the ground at a suitable location. Subsequently, multiple monitoring assemblies stored and carried are sequentially placed in the drilling positions. The monitoring column in the monitoring tube is vertically moved down to be inserted into the drilled hole in the ground. The CO2 concentration in the soil at different depths underground is monitored through the monitoring units at its peripheral ends. At the same time, all the placed monitoring assemblies are used to monitor the CO2 concentration in the soil at different locations in the forest. At the same time, additional transport carts can be added to cover a larger area, and each monitoring assembly can monitor continuously for a period of time. During the monitoring process, the transport cart can be moved to a sunny place to convert light energy into electrical energy for charging. When the monitoring assembly is out of power, the transport cart can recycle the monitoring assembly for charging, and at the same time, the charged monitoring assembly is placed, so that the monitoring device can perform monitoring tasks in the forest ecosystem for a long time, which is more convenient.

[0011] Optionally, a storage cavity with a "U"-shaped horizontal cross-section is opened at one end of the transport cart, and the monitoring component is stored in the storage cavity. The openings at both ends of the storage cavity are respectively a delivery port and a storage port. The delivery port delivers the monitoring component to the ground, and the storage port recovers the monitoring component to the storage cavity. The monitoring component also includes a battery pack located at the top. When the monitoring component moves along the storage port toward the delivery port in the storage cavity, the energy supply component charges the battery pack.

[0012] By opening a "U"-shaped storage cavity on the transport trolley, the monitoring component enters from the storage port of the storage cavity and moves along the length of the storage cavity. The battery pack of the monitoring component can be charged during the movement until it moves to the delivery port, at which time the monitoring component can be delivered. This solution makes the recovery and delivery of the monitoring component more convenient.

[0013] Optionally, the transport trolley is provided with multiple groups of translation components for synchronous horizontal sliding in the storage cavity, and the multiple groups of translation components are evenly spaced from the delivery port to the storage port, and each group of the translation components horizontally pushes the monitoring component for a certain distance. The translation component includes sliders that are respectively horizontally slidably arranged on both side walls of the storage cavity, a micro motor vertically arranged on the slider, and a push plate fixedly connected to the output shaft of the micro motor, the rotation axis of the push plate is vertical, and the push plate abuts against the side end of the monitoring tube away from the delivery port as it rotates and pushes the monitoring component as the slider moves.

[0014] The micro motor is driven to move by a horizontally sliding synchronous slider, and the micro motor drives the push plate to rotate. When the push plate rotates to be parallel to the inner wall of the storage chamber, the slider can move freely. When the push plate rotates to abut the side end of the monitoring tube, the monitoring component can be pushed toward the side of the delivery port as the slider moves, thereby making it more convenient to move multiple groups of monitoring components synchronously.

[0015] Optionally, the transport trolley is provided with vertically rotating reels on both sides of the delivery port and the storage port, and a "U"-shaped channel of the same shape as the storage cavity is opened between the two reels on the same side of the transport trolley, and the two reels on the same side roll up the screen cloth in the "U"-shaped channel, and the transport trolley is provided with a sliding hole connected to the "U"-shaped channel horizontally on the inner wall of the storage cavity, the slider is partially inserted into the sliding hole and connected to the screen cloth, and the screen cloth is rolled up along different directions on the reel to drive the slider to slide back and forth horizontally.

[0016] The screen cloth in the channel is driven to move by the scroll, thereby driving all the sliders to move synchronously, which is more convenient.

[0017] Optionally, positioning ring grooves are coaxially provided on the circumferential ends of the top and bottom of the monitoring tube, and the transport trolley is provided with an installation long groove at the bottom of the storage cavity along the length direction of the storage cavity to form two lower convex edges that are inserted into the positioning ring grooves as the transport trolley moves, and the transport trolley is provided with upper convex edges inserted into the positioning ring grooves on the tops of the two side walls of the storage cavity, and the transport trolley is provided with two "U"-shaped charging metal guide bars on the top of the storage cavity, and two charging guide columns are protruding from the top of the monitoring tube, which respectively abut against and magnetically attract the two charging metal guide bars.

[0018] By opening positioning ring grooves at the top and bottom of the monitoring tube, when the monitoring tube enters the storage cavity, the upper and lower convex edges in the storage cavity are respectively inserted into the positioning ring grooves on the upper and lower sides of the monitoring tube, thereby ensuring that the vertical height of the monitoring tube does not change when it moves, so that the charging guide column on the top of the monitoring tube can be continuously magnetically attracted to the charging metal guide bar, thereby realizing charging while moving, which is more convenient.

[0019] Optionally, a clamping claw assembly is provided at the side end of the transport trolley to clamp the monitoring assembly until it is inserted into the storage cavity. The clamping claw assembly includes a rotating connecting rod rotatably connected to the side end of the transport trolley and located between the delivery port and the storage port, a sliding seat vertically slidingly arranged at the end of the rotating connecting rod, and an electric clamp arranged on the sliding seat.

[0020] The monitoring component is clamped by the clamping claw component, which makes it more convenient to retract the monitoring component to the storage port and place it on the ground through the delivery port.

[0021] Optionally, a stabilizing flange supported on the ground is coaxially provided along the outer periphery of the bottom of the monitoring tube, and nails driven into the ground are evenly arrayed on the lower end surface of the stabilizing flange.

[0022] By setting a stabilizing flange on the outer edge of the bottom of the monitoring tube, the stabilizing flange can be more stably supported vertically on the ground when the monitoring component is deployed. At the same time, combined with the nails on the lower end face of the stabilizing flange, the monitoring component can work more stably.

[0023] Optionally, the transport trolley is provided with running tires on both side ends, and the running tires are off-road tires and running protrusions are evenly provided on the circumferential side ends.

[0026] The drilling sleeve is driven to move vertically downward by the vertically moving drilling slide, and the rotating drilling sleeve is drilled into the ground driven by the drill teeth at the lower end, and then the drilling slide is moved upward. At this time, the drilling sleeve carries the soil column, and then the drilling sleeve is driven to move horizontally to the axis symmetrical to the soil-breaking drill rod by the yield slide, and the drilling sleeve is moved vertically downward and rotated, so that the soil-breaking drill rod drills into the drilling sleeve and crushes the soil column, thereby facilitating subsequent drilling. At the same time, the carried soil column is crushed on the side of the ground opening, which does not affect the subsequent deployment of monitoring components and is more convenient.

[0027] Optionally, the energy supply component includes a solar photovoltaic panel arranged on the upper end of the transport trolley and an energy storage battery embedded in the top of the transport trolley. The solar photovoltaic panel is arranged at an angle and the middle part of the lower end face is vertically rotated and connected to the transport trolley.

[0028] By rotating and installing a solar photovoltaic panel on the top of the transport trolley, the light energy can be converted into electrical energy when the transport trolley moves to a sunny position, and then stored in the energy storage battery, so as to facilitate the subsequent movement of the transport trolley, drilling of the drilling component, deployment and recovery of the monitoring component, and detection of the monitoring component.

[0029] (3) Beneficial effects

[0030] The beneficial effects of the present invention are: the monitoring device for the CO2 concentration in the soil of a forest ecosystem of the present invention, when monitoring the CO2 concentration in the soil of a forest ecosystem through the monitoring device, moves in the forest through a transport cart, drills the ground at a suitable position through a drilling component, and then drops a plurality of monitoring components stored and carried into the drilling position in turn, and the monitoring column in the monitoring tube moves vertically downward to be inserted into the drill hole on the ground, and monitors the CO2 concentration in the soil at different depths underground through the monitoring unit at its peripheral end, and at the same time cooperates with all the monitoring components dropped to monitor the CO2 concentration in the soil at different positions in the forest, and at the same time, additional transport carts can be added to cover a larger range, and each monitoring component can continue to monitor for a period of time.

[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0038] The embodiment of the present invention proposes a monitoring device for the CO2 concentration in the soil of a forest ecosystem. When the monitoring device is used to monitor the CO2 concentration in the soil of a forest ecosystem, the device moves in the forest through a transport cart, and drills holes in the ground at appropriate locations through a drilling assembly. Subsequently, multiple monitoring assemblies stored and carried are sequentially dropped into the drilling positions. The monitoring column in the monitoring tube moves vertically downward and is inserted into the drilled hole on the ground. The CO2 concentration in the soil at different depths underground is monitored through the monitoring units at its peripheral ends. At the same time, all the deployed monitoring assemblies are used to monitor the CO2 concentration in the soil at different locations in the forest. At the same time, additional transport carts can be added to cover a larger range, and each monitoring assembly can continue to monitor for a period of time. During the monitoring process, the transport cart can be moved to a place with sunlight to convert light energy into electrical energy for charging. When the monitoring assembly is out of power, the transport cart can recycle the monitoring assembly for charging, and at the same time drop the charged monitoring assembly, so that the monitoring device can perform monitoring tasks in the forest ecosystem for a long time, which is more convenient.

[0039] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] Reference Figure 1 and Figure 2 A device for monitoring the CO2 concentration in the soil of a forest ecosystem comprises a transport trolley 1 that moves along the ground, a drilling assembly 2 that is arranged on the front side of the transport trolley 1 and can drill holes in the ground, a plurality of monitoring assemblies 3 that are housed inside the transport trolley 1 and can be sequentially placed at the drilling positions of the drilling assembly 2, and an energy supply assembly 4 that is arranged on the top of the transport trolley 1.

[0041] The drilling assembly 2 includes a sliding plate 21 that slides horizontally on the front side of the transport trolley 1 via a lead screw, a drilling slide 22 that slides vertically on the side of the sliding plate 21 via a lead screw, and a drilling sleeve 23 that is rotatably connected to the lower end of the drilling slide 22 via a motor. Drill teeth 24 are evenly distributed around the lower end of the drilling sleeve 23. A soil-breaking drill rod 25 is vertically mounted on one side of the drilling sleeve 23 at the front side of the transport trolley 1. The soil-breaking drill rod 25 rotates with the drilling sleeve 23, penetrates the interior of the drilling sleeve 23, and crushes the soil column carried by the drilling sleeve 23. The drilling sleeve 23 is driven to move vertically downward by the vertically moving drilling slide 22, and the rotating drilling sleeve 23 is drilled into the ground driven by the drill teeth 24 at the lower end, and then the drilling slide 22 is moved upward. At this time, the drilling sleeve 23 carries the soil column, and then the drilling sleeve 23 is driven to move horizontally to the top of the soil-breaking drill rod 25 axially symmetrically by the giving way slide 21, and then the drilling sleeve 23 is moved vertically downward and rotated, so that the soil-breaking drill rod 25 drills into the drilling sleeve 23 and crushes the soil column, thereby facilitating subsequent drilling. At the same time, the carried soil column is crushed to the side of the ground opening, which does not affect the subsequent deployment of the monitoring component 3 and is more convenient.

[0042] See also Figure 3 and Figure 4 The monitoring assembly 3 includes a monitoring tube 31 supported and fixed on the upper end of the ground, a battery pack 32 built into the top of the monitoring tube 31, a monitoring column 33 that is vertically slidably accommodated in the monitoring tube 31 and can be inserted into a borehole on the ground, and multiple layers of monitoring units 34 evenly spaced along the length of the monitoring column 33. Each layer of monitoring units 34 includes multiple monitoring units evenly spaced circumferentially on the circumferential side wall of the monitoring column 33.

[0043] A storage cavity 11 with a "U"-shaped horizontal cross-section is provided at one end of the transport trolley 1. The monitoring component 3 is stored in the storage cavity 11. The openings at both ends of the storage cavity 11 are respectively a delivery port 12 and a storage port 13. The delivery port 12 delivers the monitoring component 3 to the ground, and the storage port 13 recovers the monitoring component 3 to the storage cavity 11.

[0044] The transport trolley 1 is synchronously and horizontally slidable in the storage chamber 11, and is provided with multiple groups of translation components 14. The multiple groups of translation components 14 are evenly spaced from the delivery port 12 to the storage port 13. Each group of translation components 14 horizontally pushes the monitoring component 3 for a distance. The translation component 14 includes sliders 141 respectively arranged on the two side walls of the storage chamber 11 for horizontal sliding, a micro motor 142 vertically arranged on the slider 141, and a push plate 143 fixedly connected to the output shaft of the micro motor 142. The rotation axis of the push plate 143 is vertical. The push plate 143 abuts against the side end of the monitoring tube 31 away from the delivery port 12 as it rotates and moves with the slider 141 to push the monitoring component 3, and the transport The trolley 1 is provided with a reel 15 for vertical rotation on both sides of the delivery port 12 and the storage port 13 respectively. A "U"-shaped channel 16 of the same shape as the storage chamber 11 is opened between the two reels 15 on the same side of the transport trolley 1. The two reels 15 on the same side have screen cloth 17 rolled up in the "U"-shaped channel 16. The transport trolley 1 is provided with a sliding hole 18 connected to the "U"-shaped channel 16 horizontally on the inner wall of the storage chamber 11. The adjacent sliding holes 18 on the same side are arranged one above and one below and the ends close to each other overlap in the vertical direction. The slider 141 is partially inserted into the sliding hole 18 and connected to the screen cloth 17. The screen cloth 17 is rolled up in different directions on the reel 15, driving the slider 141 to slide back and forth horizontally. The screen cloth 17 in the channel is driven to move by the reel 15, thereby driving the slider 141 to move synchronously. The slider 141 that slides horizontally and synchronously drives the micro motor 142 to move, and the micro motor 142 drives the push plate 143 to rotate. When the push plate 143 rotates to be parallel to the inner wall of the storage chamber 11, the slider 141 can move freely. When the push plate 143 rotates to abut the side end of the monitoring tube 31, the monitoring component 3 can be pushed toward the side of the delivery port 12 as the slider 141 moves, thereby making it more convenient to synchronously move multiple groups of monitoring components 3.

[0045] A positioning ring groove 311 is coaxially provided at the top and bottom circumferential ends of the monitoring tube 31. The transport trolley 1 is provided with a mounting long groove 19 at the bottom of the storage chamber 11 along the length direction of the storage chamber 11 to form two lower convex edges 191 that are inserted into the positioning ring groove 311 as the transport trolley 1 moves. The transport trolley 1 is provided with upper convex edges 111 that are inserted into the positioning ring groove 311 at the top of the two side walls of the storage chamber 11. The transport trolley 1 is provided with two "U"-shaped charging metal guide bars 112 at the top of the storage chamber 11. Two charging guide columns 35 are protruding from the top of the monitoring tube 31, which respectively abut against the two charging metal guide bars 112 and are magnetically attracted. When the monitoring tube 31 enters the storage chamber 11, the upper convex edge 111 and the lower convex edge 191 in the storage chamber 11 are respectively inserted into the positioning ring grooves 311 on the upper and lower sides of the monitoring tube 31, thereby ensuring that the vertical height of the monitoring tube 31 will not change when it moves, so that the charging guide column 35 on the top of the monitoring tube 31 can continue to be magnetically attracted to the charging metal conductor 112, thereby realizing charging while moving, which is more convenient.

[0046] See also Figure 1 A clamping jaw assembly 5 is provided at the side of the transport trolley 1 to clamp the monitoring assembly 3 until it is inserted into the storage chamber 11. The clamping jaw assembly 5 includes a rotating connecting rod 51, which is driven by a motor and is connected to the side of the transport trolley 1 and is located between the delivery port 12 and the storage port 13. A sliding seat 52 is provided at the end of the rotating connecting rod 51 and slides vertically via a lead screw. An electric clamping jaw 53 is fixed to the sliding seat 52. The clamping jaw assembly 5 clamps the monitoring assembly 3, making it easier to retrieve the monitoring assembly 3 to the storage port 13 and place it on the ground from the delivery port 12.

[0047] See also Figure 3 The monitoring tube 31 is coaxially mounted with a stabilizing flange 312 along its outer periphery, supporting the ground. The lower end of the stabilizing flange 312 is evenly arrayed with spikes 313 driven into the ground. When the monitoring assembly 3 is deployed, the stabilizing flange 312 provides a more stable vertical support on the ground, and the spikes 313 on the lower end of the stabilizing flange 312 ensure more stable operation.

[0048] See also Figure 1 The transport trolley 1 is provided with running tires 6 on both sides. The running tires 6 are off-road tires and running protrusions 61 are evenly provided on the side ends.

[0049] The energy supply assembly 4 comprises a solar photovoltaic panel 41 mounted on the upper end of the transport trolley 1 and an energy storage battery 42 embedded within the top of the transport trolley 1. The solar photovoltaic panel 41 is tilted, with the middle portion of its lower end vertically pivoted to connect to the transport trolley 1. When the transport trolley 1 reaches a location exposed to sunlight, it converts sunlight into electrical energy, which is then stored in the energy storage battery 42. This energy is then used to power the subsequent movement of the transport trolley 1, the drilling of the drilling assembly 2, the deployment and retrieval of the monitoring assembly 3, and the monitoring assembly 3's testing operations.
