Description

Technical Field

[0001] The invention relates to the technical field of forest carbon sink measurement and detection, and in particular to a forest carbon sink measurement and detection device. Background Art

[0002] Forest carbon sink refers to the ability of forests to absorb and store carbon dioxide. The ability of forest vegetation to absorb carbon dioxide can be detected through forest carbon sink, so as to mitigate the problem of global warming by planting vegetation. Currently, forest carbon sink measurement and detection devices are used in the market to measure and detect forest carbon sinks.

[0003] A forest carbon sink measurement and detection device is disclosed in the patent application with reference announcement number CN219142771U. The detection device is equipped with a sealing plate and an air vent. The sealing plate is rotated to make the air vent coincide with the left end of the gas collecting pipe at the corresponding position, thereby facilitating the gas to enter one of the gas collecting pipes for collection. A filter plate is also installed to filter and isolate impurities or leaves in the air when collecting air, so that impurities cannot enter the gas collecting pipe, thereby facilitating the protection of the gas collecting pipe.

In actual operation, the filter plate is easily blocked by impurities, affecting the air intake, which is very likely to interfere with subsequent metering and detection, affecting the accuracy of metering and detection. At the same time, the filter plate cannot automatically complete the cleaning work, and is at a high place. After a certain period of operation, technicians are required to climb up for maintenance and cleaning, which increases the difficulty of maintenance and poses a greater safety hazard.

The air chamber 13 is composed of a circular cavity with an open top design and a cover plate. The cover plate is detachably fixed on the top of the air chamber 13, and the cover plate is connected to the inner wall of the metering box 2. The interior of the air chamber 13 is hollow, and an exhaust pipe 15 is connected and installed on the side of the metering box 2 close to the air chamber 13.

[0044] It is worth noting that: when the gas source is detected: by providing a detection component, the detection gas is sent into the air pipe 17, and then the corresponding carbon dioxide detector 18 is used to continuously detect and analyze the gas, and the design of multiple air pipes 17 can complete separate detections for gases in different time periods, which is conducive to the technical personnel to collect and summarize the detection data separately to avoid confusion of the detection data, and then the detected gas is summarized through the air chamber 13, and finally the gas is discharged through the exhaust pipe 15 to complete the detection, and the opening and closing of the exhaust pipe 15 can be controlled by the solenoid valve, which is convenient for the subsequent control of the flow of gas;

[0045] In the embodiment of the present invention, the switching assembly includes a baffle 20 rotatably mounted in a circular kit 19, the baffle 20 is provided with air holes 21 that cooperate with the air pipes 17, and the baffle 20 is in rotational contact with the six air pipes 17, a synchronous shaft 22 is fixedly mounted between the turntable 5 and the baffle 20, a first gear 23 is sleeved on the outside of the synchronous shaft 22, and a switching motor 24 is installed at the top of the circular kit 19 through a bracket, a second gear 25 is installed at the output end of the switching motor 24, and the first gear 23 is sleeved on the outer surface of the synchronous shaft 22.

[0046] It is worth noting that: when performing switching detection: a switching component is provided, the switching motor 24 is started, and the second gear 25 is driven to rotate. Through the meshing transmission of the first gear 23 and the third gear 26, the synchronous shaft 22, the turntable 5 and the baffle 20 are synchronously rotated, so that the air hole 21 on the baffle 20 corresponds to another air pipe 17. When the turntable 5 rotates, the annular filter 8 follows the rotation to complete the position switching, so that the other filtering area 9 of the annular filter 8 corresponds to the intake pipe 11, thereby completing the synchronous follow-up switching of the air pipe 17 and the annular filter 8, avoiding the problem of the fixed filter screen affecting the intake volume, ensuring the cleanliness of the annular filter 8, avoiding the accumulation of impurities affecting the intake volume, keeping the introduced gas clean, and improving the detection accuracy.

[0047] Embodiment 3: Based on the active cleaning mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the active cleaning mechanism.

[0048] like Fig.11 and Fig.12As shown, the active cleaning mechanism includes a cleaning pipe 29 connected and installed on one side of the bottom of the air chamber 13, the other end of the cleaning pipe 29 is introduced between the baffle 20 and the annular filter 8, and a No. 2 one-way valve for unidirectionally discharging the gas from the air chamber 13 is installed at the end of the cleaning pipe 29, a cleaning chamber 30 is installed at the bottom of one side of the circular sleeve 4, the cleaning chamber 30 is arranged in coordination with the cleaning space 7, the cleaning chamber 30 is detachably fixedly connected to the circular sleeve 4 by bolts, the cleaning chamber 30 is designed to be open toward the side of the annular filter 8, and the cleaning chamber 30 is in rotational contact with the annular filter 8, a spray chamber 31 is installed at the top of the cleaning chamber 30, a plurality of spray holes are evenly connected and opened on the spray chamber 31, and the tail of the cleaning pipe 29 passes through the cleaning chamber 30 and is connected with the spray chamber 31, and a square tube 32 is installed at the bottom of the circular sleeve 4, the square tube 32 is arranged in coordination with the cleaning chamber 30, and the two are always Corresponding to a cleaning space 7, impurities in the cleaning space 7 are discharged through the square tube 32, a plugging plate 33 is detachably installed at the bottom of the square tube 32, and guide rods 34 are symmetrically installed on both sides of the square tube 32 at the bottom of the metering box 2, and the two guide rods 34 slide through the plugging plate 33 accordingly, and a top rod 35 is installed on the upper surface of the plugging plate 33, and a lifting plate 36 is detachably installed on the top of the top rod 35. The lifting plate 36 is separated from the annular filter 8 and is arranged at intervals. A brush 37 is detachably installed on the lifting plate 36 facing the annular filter 8. The brush 37 is specifically made of soft material and can be deformed to ensure stable cleaning work. The brush 37 contacts the concave area 10 of the annular filter 8 to complete cleaning. Under normal circumstances, the brush 37 contacts the annular filter 8. When the brush 37 is close to the concave area 10, the brush 37 contacts the concave area 10 to complete scraping and cleaning;

[0049] It is worth noting that when the annular filter screen 8 is cleaned in coordination: an active cleaning mechanism is provided, the solenoid valve of the exhaust pipe 15 is closed, and the gas detected in the air chamber 13 is sent to the cleaning pipe 29, and then the gas enters the spray cavity 31 of the cleaning chamber 30, and is sprayed out through multiple spray holes to back-blow and clean the annular filter screen 8, and then the impurities and gas are discharged through the square tube 32 together, and the above-mentioned spraying work is continued to perform detailed cleaning work on the annular filter screen 8, which reduces the cleaning difficulty of the technicians and the maintenance cost of the annular filter screen 8, so that the detection equipment can continue to detect and operate without stopping for cleaning;

[0050] At the same time, a blocking plate 33 is provided at the bottom of the square tube 32. Under normal circumstances, the blocking plate 33 completes the blocking of the bottom of the square tube 32 to keep it airtight, and the blocking plate 33 follows the trigger rod 39 to correspond to the cam block 28 on the switching disk 27. When the switching component switches the air hole 21 to another air pipe 17, the switching disk 27 follows the rotation of the turntable 5. Under the guidance of the trajectory of the cam block 28, the cam block 28 thereon contacts the rotating wheel 40 at the top of the trigger rod 39 to complete the extrusion guidance, prompting the trigger rod 39 and the pressure plate 41 to move downward synchronously, compressing the return spring 42, and the trigger rod 39 moves downward.

Since a first rack 44 and a second rack 45 are correspondingly arranged on both sides of the guide gear 43, and the first rack 44 is fixedly arranged and the second rack 45 is movably arranged, when the trigger rod 39 and the guide gear 43 move downward, the guide gear 43 is restricted by the meshing of the first rack 44 to complete the rotation, so that the second rack 45 The second rack 45 pulls the plugging plate 33 downward to open the square tube 32, and the plugging plate 33 moves downward, driving the push rod 35 and the lifting plate 36 downward. The lifting plate 36 moves downward and drives the brush 37 to move to first scrape and clean the annular filter 8, further improving the cleaning effect and cleaning efficiency. The extended stroke design of the second rack 45 allows the lifting plate 36 to obtain sufficient movement in a small space, so that the annular filter 8 can be fully cleaned, reducing the cleaning dead angle range. On the contrary, when the switching disk 27 rotates the cam block 28 and the trigger rod 39 is misaligned, the reset spring 42 drives the trigger rod 39 to reset, and the second rack 45, the lifting plate 36 and the plugging plate 33 move upward synchronously to complete the reset. At this time, the plugging plate 33 blocks the other tube 32 and completes the closure, which is conducive to the control of the state of the other tube 32.

The pressure plate 41 is located below the circular sleeve 19, and a reset spring 42 is sleeved on the outside of the trigger rod 39. The reset spring 42 is located between the pressure plate 41 and the guide platform 38. The spring 42 pushes the trigger rod 39 to move toward the switching disk 27, and a guide gear 43 is rotatably installed at the bottom of the trigger rod 39. A No. 1 rack 44 is fixedly installed on one side of the guide platform 38 in the metering box 2, and a No. 2 rack 45 is slidably installed on one side of the guide platform 38 in the metering box 2.
