[0002] Forest carbon sink refers to the absorption of carbon dioxide in the atmosphere by forest plants and its fixation in vegetation or soil, thereby reducing the concentration of this gas in the atmosphere.

[0003] In the prior art, a Chinese utility model patent with the publication number CN204945121U discloses a device for measuring and detecting the carbon sink capacity of plantation forests. By arranging a test tube at the lower end of a cylinder and placing a carbon dioxide detector in the middle of the interior of a box body, while the carbon dioxide detector collects the carbon dioxide concentration, the cylinder can be controlled to act by a control device to sample the real-time carbon dioxide for subsequent comparative analysis, improving the reliability of carbon sink capacity measurement. After one round of sampling, the box body can be ventilated by a fan, improving the processing speed of the device.

[0023] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0024] As Figure 1-5As shown in the figure, in the embodiment, a measurement and detection device for the carbon sequestration capacity of a plantation is provided, which includes a moving base 1, a lifting mechanism 2, a housing 3, and a detection mechanism 4. A lifting mechanism 2 is arranged on the moving base 1, the output end of the lifting mechanism 2 is connected to the housing 3, and a detection mechanism 4 is arranged inside the housing 3. The detection mechanism 4 includes a detection tank 41, a detection probe 42, a piston plate 43, a piston rod 44, a sliding frame 45, a first motor 46, a first rotating block 47, a pin shaft 48, and an air intake assembly 5. The detection tank 41 is fixedly arranged on the inner bottom wall of the housing 3, and a detection probe 42 is arranged on the inner side wall of the detection tank 41 for detecting the concentration of carbon dioxide. The piston plate 43 is slidably connected to the inner side wall of the detection tank 41, and a piston rod 44 is fixedly arranged on one side of the piston plate 43. The free end of the piston rod 44 extends out of the detection tank 41 and is connected to the sliding frame 45. The first motor 46 is fixedly arranged on the inner top wall of the housing 3, the output end of the first motor 46 is connected to the first rotating block 47, a pin shaft 48 is eccentrically arranged on the first rotating block 47, and the pin shaft 48 is slidably connected to the sliding frame 45. An air intake assembly 5 is arranged on one side of the detection tank 41. In this embodiment, walking wheels are arranged at the bottom of the moving base 1, which is convenient for quickly moving the device to the area to be detected and is easy to operate. The provided lifting mechanism 2 is used to control the lifting of the housing 3, so that the detection mechanism 4 can measure the carbon dioxide concentration in different height areas. Among them, an exhaust hole is arranged on one side of the detection tank 41 close to the sliding frame 45, so that when the piston plate 43 slides left and right, the outside air can be inhaled into the chamber on the left side of the piston plate 43, and the air in the chamber on the right side of the piston plate 43 can be discharged to ensure the normal operation of the device; a groove is arranged on the inner side wall of the detection tank 41, the detection probe 42 is a carbon dioxide concentration sensor, and the detection probe 42 is arranged in the groove. The provided detection probe 42 is used to detect the concentration of carbon dioxide inhaled into the detection tank 41 to eliminate the influence of carbon dioxide concentration fluctuations caused by external wind force and improve the accuracy of the detection results; a rubber sealing pad is circumferentially arranged on the side surface of the piston plate 43 to block the gap between the piston plate 43 and the inner side wall of the detection tank 41 to prevent gas leakage from affecting the detection results; the piston rod 44 is horizontally arranged, and one end of the piston rod 44 is fixedly connected to the center of the piston plate 43 to push the piston plate 43 to slide left and right to realize the functions of inhaling and exhausting air; the sliding frame 45 is a rectangular frame body, the sliding frame 45 is horizontally arranged below the first rotating block 47, and the sliding frame 45 is perpendicular to the piston rod 44. The provided first motor 46 can drive the first rotating block 47 to rotate, and then drive the pin shaft 48 to rotate synchronously. During the movement of the pin shaft 48, relative sliding will occur with the sliding frame 45, so as to realize the purpose of driving the piston plate 43 to move left and right through the piston rod 44; the provided air intake assembly 5 is used to filter impurities such as flying insects to ensure the accuracy of the detection. In addition, a total control box is also arranged on the moving base 1, which can control the coordinated work of the moving base 1, the lifting mechanism 2, and the detection mechanism 4, and the total control box can also count the carbon dioxide concentration data detected by the detection probe 42.

[0025] Specifically, the intake assembly 5 includes a switching pipe 51, an air pipe 52, a second rotating block 53, a one-way valve 54, a driving part 55, and a filter 57. The switching pipe 51 is horizontally arranged on one side of the detection tank 41, and one end of the switching pipe 51 is communicated with the detection tank 41. The other end of the switching pipe 51 is connected with two air pipes 52. A second rotating block 53 is rotatably connected in the switching pipe 51. Two through holes 531 are arranged in a cross shape on the second rotating block 53. A one-way valve 54 is arranged at one end of the through hole 531 close to the detection tank 41. The driving part 55 is arranged on the detection tank 41 and is used to drive the second rotating block 53 to rotate. A filter 57 is also arranged on the air pipe 52. In this embodiment, the radius of the switching pipe 51 should be greater than the diameter of the air pipe 52. The second rotating block 53 can rotate in the switching pipe 51 so that the end parts of the two air pipes 52 can be respectively aligned with one of the through holes 531, thereby realizing the intake and exhaust functions. The one-way valve 54 arranged makes it so that only one of the through holes 531 can intake air, while the other through hole 531 can only exhaust air. For example, when the piston plate 43 slides to the right, the outside air enters the detection tank 41 after passing through one of the air pipes 52 and the through hole 531 that can only intake air. When the piston plate 43 slides to the left, the air in the detection tank 41 is discharged through the through hole 531 that can only exhaust air and the other air pipe 52. In addition, the two air pipes 52 should be at the same horizontal height so that when the two air pipes 52 alternately intake and exhaust air, they act on the air at the same horizontal height to eliminate the influence of height change on the detection result. The filter 57 arranged is used to remove impurities such as flying insects in the air, and the driving part 55 arranged can drive the second rotating block 53 to rotate, and then make the two air pipes 52 alternately intake and exhaust air, so as to remove the impurities accumulated in the air pipes 52 and the filter 57 to ensure the filtering effect.

[0026] Specifically, the driving unit 55 includes a bracket 551, a support plate 552, a control unit 56, a first rotating shaft 553, a first rotating gear 554, a first bevel gear 555, and a second bevel gear 556. The bracket 551 is vertically fixed to the top of the detection tank 41. A support plate 552 is slidably connected to the bracket 551. The bottom of the support plate 552 is connected to a control unit 56 for controlling the lifting of the support plate 552. A first rotating shaft 553 is rotatably connected to the support plate 552. One end of the first rotating shaft 553 is connected to a first rotating gear 554. The first rotating gear 554 meshes with the tooth groove on the side of the second rotating block 53. The other end of the first rotating shaft 553 is connected to a second bevel gear 556. The first bevel gear 555 is fixed to the power output shaft of the first motor 46. The first bevel gear 555 meshes with the second bevel gear 556. In this embodiment, the provided bracket 551 is of a rectangular frame structure, and the provided control unit 56 can drive the support plate 552 to slide up and down on the bracket 551, thereby controlling whether the first rotating gear 554 meshes with the second rotating block 53, the first bevel gear 555, and the second bevel gear 556. The first rotating shaft 553 is horizontally arranged, and the first bevel gear 555 is located below the second bevel gear 556, and the first rotating gear 554 is located above the switching pipe 51. The first rotating shaft 553 can rotate on the support plate 552, so as to drive the second rotating block 53 to rotate through the first rotating gear 554.

[0027] Specifically, the control unit 56 includes a driving wheel 561, a second rotating shaft 562, a driven wheel 563, a belt 564, a turntable 565, a toggle rod 566, a grooved wheel 567, a rotating cylinder 568, and a ejector rod 569. The driving wheel 561 is fixedly arranged on the power output shaft of the first motor 46. The second rotating shaft 562 is rotatably connected to the top of the detection tank 41. The driven wheel 563 and the turntable 565 are fixedly arranged on the second rotating shaft 562. The driving wheel 561 and the driven wheel 563 are drivingly connected by the belt 564. The toggle rod 566 is arranged on the turntable 565. A grooved wheel 567 is arranged on one side of the second rotating shaft 562. The grooved wheel 567 is rotatably connected to the detection tank 41. The grooved wheel 567 is provided with a toggle groove 5671 that cooperates with the toggle rod 566. The rotating cylinder 568 is fixedly arranged on the top of the grooved wheel 567. The rotating cylinder 568 is provided with a wedge-shaped groove 5681. The bottom end of the ejector rod 569 is slidably connected to the wedge-shaped groove 5681. The top end of the ejector rod 569 is connected to the support plate 552. In this embodiment, the driving wheel 561 and the driven wheel 563 are both transmission wheels, and the driving wheel 561 and the driven wheel 563 rotate synchronously through the belt 564. The turntable 565 is located above the driven wheel 563, and the diameter of the turntable 565 should be greater than that of the driven wheel 563. The toggle rod 566 is arranged vertically, and the top end of the toggle rod 566 is fixedly arranged on the circumference of the turntable 565. Two or more toggle grooves 5671 are evenly arranged on the grooved wheel 567, so that the turntable 565 drives the grooved wheel 567 to rotate a certain angle through the toggle rod 566 every time it rotates one week. The rotating cylinder 568 and the grooved wheel 567 are coaxially arranged. The wedge-shaped groove 5681 is arranged vertically, and the number of the wedge-shaped grooves 5681 corresponds to that of the toggle grooves 5671 one by one. When the rotating cylinder 568 rotates, the ejector rod 569 slides relative to the wedge-shaped groove 5681. When the bottom end of the ejector rod 569 is located at the bottom end of the wedge-shaped groove 5681, the support plate 552 is in the lowest position. At this time, the first rotating gear 554 is in mesh with the second rotating block 53, the first bevel gear 555, and the second bevel gear 556. On the contrary, when the bottom end of the ejector rod 569 is located at the top end of the wedge-shaped groove 5681, the support plate 552 is in the highest position. At this time, the first rotating gear 554 is disengaged from the second rotating block 53, the first bevel gear 555, and the second bevel gear 556. The ejector rod 569 is arranged vertically.

[0028] Specifically, the filter 57 includes a filter cylinder 571 and a filter net 572. The filter cylinder 571 is fixedly arranged on the inner side wall of the housing 3, and the air pipe 52 is connected to the filter cylinder 571. The filter net 572 is arranged vertically in the filter cylinder 571. In this embodiment, the diameter of the filter cylinder 571 is slightly larger than that of the air pipe 52. The arranged filter net 572 can filter out impurities such as flying insects in the air. When the air pipe 52 connected to the filter cylinder 571 is in the state of blowing air outward, the flying insects and other impurities on the filter net 572 can be blown off to prevent the blockage of the filter holes and the situation of poor air flow.

[0029] Specifically, a collection bin 573 is further provided at the bottom of the filter cartridge 571. The collection bin 573 is communicated with the filter cartridge 571 through an inlet 574. A door panel 575 is horizontally arranged above the inlet 574, and the door panel 575 is slidably connected to the inner bottom wall of the filter cartridge 571. A wind baffle 576 is arranged on the door panel 575. In this embodiment, the collection bin 573 is located at the outer bottom of the housing 3, and the provided collection bin 573 is used to collect the impurities falling off the filter net 572, which is convenient for subsequent treatment. The provided door panel 575 can close the inlet 574. When the air pipe 52 connected to the filter cartridge 571 is in the air inlet state, the air flow blows the wind baffle 576, causing the door panel 575 to move towards the side close to the filter net 572, thereby closing the inlet 574. On the contrary, when the air pipe 52 connected to the filter cartridge 571 is in the air outlet state, the air flow blows the wind baffle 576, causing the door panel 575 to move away from the side of the filter net 572, thereby opening the inlet 574. At this time, the blown-off impurities will fall into the collection bin 573 through the inlet 574 for collection, so as to avoid accumulation and blockage in the filter cartridge 571.

[0030] Specifically, the air pipe 52 extends out of the housing 3 and is connected to the air guiding nozzle 58, and the openings of the two air guiding nozzles 58 face in opposite directions. In this embodiment, the air guiding nozzle 58 is of a conical structure, and the provided air guiding nozzle 58 can prevent rainwater from being sucked into the air pipe 52. And the two air guiding nozzles 58 face in opposite directions, which can prevent the blown air flow from being sucked in again, ensuring the accuracy of the detection result.

[0031] Specifically, the lifting mechanism 2 includes a guide rod 21, a lifting seat 22, a second motor 23, a lead screw 24, a slider 25 and a transmission rod 26. The guide rod 21 is vertically arranged on the moving seat 1, and the lifting seat 22 is slidably connected to the guide rod 21. The housing 3 is fixedly arranged on the top of the lifting seat 22. The second motor 23 is fixedly arranged on the moving seat 1. The output end of the second motor 23 is connected to the lead screw 24. The slider 25 is threadedly connected to the lead screw 24, and the slider 25 is slidably connected to the moving seat 1. One end of the transmission rod 26 is hinged to the slider 25, and the other end of the transmission rod 26 is hinged to the bottom of the lifting seat 22. In this embodiment, the guide rod 21 is vertically arranged. The provided second motor 23 can drive the lead screw 24 to rotate, so that the slider 25 slides left and right on the moving seat 1. Hinge seats are arranged at both ends of the transmission rod 26 to realize the hinge with the slider 25 and the lifting seat 22. The transmission rod 26 can swing relative to the slider 25, and then drive the lifting seat 22 to slide up and down along the guide rod 21. Scale lines are also arranged on the guide rod 21 to facilitate the staff to confirm the height of the detection mechanism 4.

[0032] Working principle: When in use, push the device to the area to be detected, and then start the first motor 46. The first motor 46 drives the first rotating block 47 to rotate. The first rotating block 47 drives the sliding frame 45 to move left and right through the pin shaft 48. The sliding frame 45 drives the piston plate 43 to move synchronously through the piston rod 44. That is, when the first motor 46 drives the first rotating block 47 to rotate half a circle, the piston plate 43 will move to the right to the rightmost end. At this time, the outside air will be sucked into the detection tank 41 through one of the air pipes 52 and the through hole 531, and then the first motor 46 stops working, and the detection probe 42 measures the carbon dioxide concentration in the detection tank 41. When the detection is completed, the first motor 46 drives the first rotating block 47 to continue to rotate half a circle. At this time, the piston plate 43 moves to the left to the leftmost end, and the air in the detection tank 41 will be discharged from the other air pipe 52 to realize the detection operation. At the same time, the first motor 46 will also drive the driving wheel 561 and the first bevel gear 555 to rotate. The driving wheel 561 drives the driven wheel 563 to rotate through the belt 564. The driven wheel 563 drives the second rotating shaft 562 to rotate. The second rotating shaft 562 drives the rotating disk 565 to rotate. The rotation of the rotating disk 565 drives the toggle rod 566 to rotate. The toggle rod 566 cooperates with the toggle groove 5671, so that the rotating disk 565 can drive the groove wheel 567 to rotate a certain angle every time it rotates one circle. The rotation of the groove wheel 567 drives the rotating drum 568 to rotate synchronously, so that the top rod 569 will slide in the wedge groove 5681, thereby controlling the support plate 552 to rise or fall. When the support plate 552 is at the lowest end, the first rotating gear 554 is in meshing with the second rotating block 53, the first bevel gear 555 and the second bevel gear 556. State, at this time, the first bevel gear 555 drives the second bevel gear 556 to rotate, and the second bevel gear 556 drives the first rotating gear 554 to rotate through the first rotating shaft 553, and the first rotating gear 554 rotates to drive the second rotating block 53 to rotate, so that the positions of the two through holes 531 are swapped with each other, thereby swapping the functions of the two air pipes 52, that is, when the driving wheel 561 rotates one circle, the supporting plate 552 is lifted up, so that the first rotating gear 554 and the second rotating block 53, the first bevel gear 555 and the second bevel gear 556 are all in a disengaged state, and when it continues to rotate one circle, the first rotating gear 554 and the second rotating block 53, the first bevel gear 555 and the second bevel gear 556 are all in a meshing state, and this cycle is repeated, thereby realizing the continuous switching of the working states of the two air pipes 52. When the air pipe 52 is in the air intake state, the filter 572 will filter out impurities such as flying insects in the air. At the same time, the airflow will act on the wind shield 576, thereby driving the door panel 575 to move toward the side close to the filter 572 to close the inlet 574. Conversely, when the air pipe 52 is in the air exhaust state, the airflow will move the door panel 575 to the side away from the filter 572 to open the inlet 574. At this time, the impurities on the filter 572 will be blown off by the airflow and will fall into the collection bin 573 for storage, thereby preventing impurities from accumulating in the filter cartridge 571 and causing blockage of the air pipe 52 and the filter 572.
