[0017] SS001. Deployment: Before data collection, deploy this carbon verification data collection device at the designated spatial collection location. After deployment, the carbon emission analyzer connects to the external remote data receiving terminal in real time via wireless signal transmission.

[0018] SS002, Data Acquisition: During data acquisition, the first motor and axial flow air purifier continuously output speed.

In the initial mode, driven by the lifting push rod, the transmission bevel gear ring disengages from the driven bevel gear. Also in the initial mode, the two pump plugs move fully outward under the drive of the transmission screw, allowing the gas inside the acquisition chamber to be fully exhausted. During acquisition, one acquisition chamber is directly opposite the sample inlet tube. When this acquisition chamber is directly opposite the sample inlet tube, driven by the lifting push rod, the transmission bevel gear ring contacts the driven bevel gear. After a specified time of contact between the transmission bevel gear ring and the driven bevel gear, the lifting push rod automatically returns to its initial position, disengaging the transmission bevel gear ring from the driven bevel gear. During the driven cycle of the transmission screw, the pump plugs extract the carbon nucleus gas sample to be acquired from the sample inlet tube, and the acquisition chamber extracts a sufficient amount of... After the gas sample is collected, the indexing cylinder is driven clockwise by the second motor to rotate 90°. The collection chamber containing the gas sample is connected to the carbon emission analyzer. The carbon emission analyzer then performs carbon verification and carbon analysis on the gas sample inside the collection chamber. When it is necessary to store the gas sample, the indexing cylinder is driven clockwise by the second motor to rotate 90° again. After the rotation is completed, the electric air valve b at a certain storage cylinder opens. After the electric air valve b opens, the pump plug containing the gas sample is driven by the transmission screw to a specified stroke, which then fully discharges the gas inside the sampling chamber into the storage cylinder. After the specified time for the storage cylinder to be filled with the sample, the electric air valve b closes. Subsequently, the indexing cylinder is driven clockwise by the second motor to rotate 90° again. After the indexing cylinder has completed its movement, the axial flow exhaust fan is turned on, which then fully empties the residual gas sample inside the collection chamber and the indexing cylinder, in preparation for the next gas sample extraction operation.

[0033] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0034] Please see Figure 1-9 The present invention is a carbon verification data acquisition device. The technical solution adopted is as follows: it includes a frame 1, and the inner wall of the frame 1 is installed with a collection cylinder 2 and a sample inlet tube 3 from top to bottom. The air outlet port of the sample inlet tube 3 is fixedly connected to the collection cylinder 2, and the port of the sample inlet tube 3 is connected to a filter module.

[0035] The gas filtration module includes an air duct 13 fixed to the tail end of the sample inlet tube 3 and a filter frame 14 fixed to the top of the air duct 13. A first motor 15 is mounted on the surface of the filter frame 14. A first rotating shaft 16 and a second rotating shaft 17 are rotatably connected to the inner wall of the connecting frame 1. The first rotating shaft 16 is driven by the first motor 15.

[0036] First bevel teeth are fixedly installed on the circumferential side of the first rotating shaft 16 and the output shaft end of the first motor 15, and the two first bevel teeth mesh with each other.

[0037] A dust-repelling frame 18 is slidably connected to the upper part of the air duct 13. A re-vibration spring 19 is installed between the opposing surfaces of the dust-repelling frame 18 and the air duct 13. A reciprocating toothed plate 20 is fixedly installed on the top surface of the dust-repelling frame 18. A vibration transmission half gear 21 that is connected to the reciprocating toothed plate 20 is fixedly installed on the circumferential side of the second rotating shaft 17.

[0038] The inner wall of the dust removal frame 18 is rotatably connected to a vibrating shaft 23, and the bottom of the vibrating shaft 23 is rotatably connected to a primary filter element 24. The inner wall of the primary filter element 24 is slidably connected to the air duct 13. A secondary spiral filter 25 is fixedly installed on the circumferential side of the vibrating shaft 23. The circumferential side of the secondary spiral filter 25 is rotatably fitted with the air duct 13. The outer filter shaft 22, the vibrating shaft 23, the second rotating shaft 17 and the primary filter element 24 are all driven by the first rotating shaft 16.

[0039] The vibration shaft 23 has a vibration transmission guide groove 22 with a top opening and slidably connected to the first rotating shaft 16. The cross-sections of the vibration transmission guide groove 22 and the first rotating shaft 16 are both regular polygons.

[0040] By setting the regular polygonal cross-section of the vibration transmission guide groove 22 and the first rotating shaft 16, the first rotating shaft 16 can continuously transmit power to the vibration shaft 23 during the up-and-down reciprocating rotation of the vibration shaft 23.

[0041] The first rotating shaft 16 and the tail end of the second rotating shaft 17 are both fixedly installed with second bevel teeth, and the two second bevel teeth mesh with each other.

[0042] The inner wall of the filter frame 14 is rotatably connected to a third rotating shaft 27. The top end of the third rotating shaft 27 and the tail end of the second rotating shaft 17 are both fixedly installed with third bevel teeth. The two third bevel teeth mesh with each other. The bottom end of the third rotating shaft 27 is fixedly installed with a transmission tooth 28. The peripheral side of the primary filter element 24 is fixedly installed with a driven gear ring 29 that meshes with the transmission tooth 28. The tooth height of the transmission tooth 28 is 6 times the tooth height of the driven gear ring 29.

[0043] By setting the tooth height difference between the transmission tooth 28 and the driven tooth ring 29, the transmission tooth 28 can continuously and effectively transmit power to the primary filter element 24 when the primary filter element 24 vibrates up and down.

[0044] When the vibrating shaft 23 rotates, the dust filtration direction of the secondary spiral filter 25 is downward;

[0045] The interior of the primary filter element 24 is evenly distributed with horizontally arranged external filter holes, and the interior of the secondary spiral filter element 25 is evenly distributed with vertically arranged internal filter holes. The diameter of the external filter holes is twice the diameter of the internal filter holes.

[0046] By setting the pore size difference between the outer and inner filter holes, a two-stage dust filtration system with a 3-way inlet tube is achieved.

[0047] By achieving a dual-stage dust filtration effect, the detection accuracy of the carbon emission analyzer 12 for the collected gas samples is effectively improved.

[0048] The bottom end of the primary filter element 24 is connected to a dust discharge valve 26;

[0049] The inner wall of the collection cylinder 2 is rotatably connected to a rotary cylinder 5 driven by a second motor 4;

[0050] The inside of the rotary cylinder 5 is equipped with a guide module driven by the air filter module. The inside of the collection cylinder 2 is respectively opened with two symmetrically arranged collection chambers 6 and two symmetrically arranged purification through holes 7. The front end of the collection chamber 6 is open and the rear end is closed. The inner wall of the collection chamber 6 is slidably connected with a pump plug 8. The inside of the collection chamber 6 is rotatably connected with a transmission screw 9 that is connected to the pump plug 8. The rear end of the transmission screw 9 is fixedly installed with a passive bevel tooth 10 driven by the guide module.

[0051] The guiding module includes a guiding groove 40 opened at the top of the first rotating shaft 16. The inner wall of the guiding groove 40 is connected to and slidably fitted with a gear shaft 30. The cross-sections of the gear shaft 30 and the guiding groove 40 are both regular polygons.

[0052] The top of the gear shaft 30 is fixedly installed with a transmission bevel gear ring 31 that mates with the passive bevel gear 10. The axial position of the collection cylinder 2 is rotatably connected to a lifting push rod 32, and the bottom end of the lifting push rod 32 is rotatably connected to the transmission bevel gear ring 31.

[0053] An axial flow air purifier 11 is installed inside the purification through hole 7. A carbon emission analyzer 12, a sample storage mechanism, and an exhaust gas discharge assembly are installed sequentially on the periphery of the collection cylinder 2 in a clockwise direction.

[0054] The carbon emission analyzer 12 is a commonly used component in existing technology, and will not be described in detail here;

[0055] The carbon emission analyzer 12 can be customized or selected according to actual needs;

[0056] The sample storage mechanism includes a sampling tube 33 that is fixedly connected to the sampling tube 2, and an electric air valve a34 is fixedly installed at the tail end of the sampling tube 33.

[0057] After each sample storage operation, the electric air valve a34 is automatically opened. After the electric air valve a34 is opened, the excess gas sample inside the sampling tube 33 is discharged. By achieving the effect of exhausting the excess gas sample, the contamination rate of the gas sample is effectively reduced during the next sample storage.

[0058] A set of connectors arranged in a linear array are installed on the bottom surface of the sampling tube 33. Each connector is equipped with an electric air valve b35. The other end of each connector is threadedly connected to a sample storage cylinder 36. A sampling valve 37 is fixedly installed at the bottom end of the sample storage cylinder 36.

[0059] Each electric air valve b35 is independently controlled by the central control host paired with this data acquisition device. After the electric air valve b35 is opened, the sample storage cylinder 36 can then perform gas sample storage operations.

[0060] The sampling valve 37 facilitates the rapid discharge of the gas sample stored inside the sample storage cylinder 36.

[0061] The exhaust gas discharge assembly includes an exhaust gas pipe 38 that is fixedly connected to the collection cylinder 2. A one-way exhaust valve 39 is fixedly installed at the connection between the exhaust gas pipe 38 and the collection cylinder 2. An axial flow exhaust fan is installed inside the exhaust gas pipe 38.

[0062] By setting the one-way exhaust valve 39, the gas entering the exhaust pipe 38 can only be discharged outward in one direction. By setting the axial flow exhaust fan, the exhaust gas entering the exhaust pipe 38 is quickly drawn out.

[0063] The axes of the exhaust pipe 38, the collection chamber 6, and the purification through hole 7, as well as the air inlet axis of the sample inlet pipe 3, are all perpendicular to the rotation axis of the rotary cylinder 5.

[0064] The data collection method for carbon verification data collection devices includes the following steps:

[0065] SS001. Deployment: Before the data collection operation, deploy this carbon verification data collection device at the designated spatial collection location. After deployment, the carbon emission analyzer 12 connects to the external remote data receiving terminal in real time via wireless signal transmission.

[0066] SS002, Data Acquisition. During data acquisition, the first motor 15 and the axial flow air purifier 11 continuously output speed. When the axial flow air purifier 11 is working, it exhausts air away from the carbon emission analyzer 12. In the initial mode, driven by the lifting push rod 32, the transmission bevel gear ring 31 disengages from the passive bevel gear 10. Also in the initial mode, the two pump plugs 8 move fully outward under the drive of the transmission screw 9, thereby fully exhausting the gas inside the acquisition chamber 6. During data acquisition... A certain collection chamber 6 is directly opposite the sample inlet tube 3. When the collection chamber 6 is directly opposite the sample inlet tube 3, under the driving action of the lifting push rod 32, the transmission bevel gear ring 31 contacts the driven bevel gear 10. After the transmission bevel gear ring 31 and the driven bevel gear 10 have been in contact for a specified time, the lifting push rod 32 automatically returns to its initial position, thereby disengaging the transmission bevel gear ring 31 from the driven bevel gear 10. During the driving cycle of the transmission screw 9, the pump plug 8 extracts the carbon nucleus gas sample to be collected from the sample inlet tube 3. After sufficient gas sample is collected, the indexing cylinder 5 is driven clockwise by the second motor 4 to rotate 90°. The sampling chamber 6 containing the gas sample is connected to the carbon emission analyzer 12. The carbon emission analyzer 12 then performs carbon verification and analysis on the gas sample inside the sampling chamber 6. When it is necessary to store the gas sample, the indexing cylinder 5 is driven clockwise by the second motor 4 to rotate 90° again. After the rotation is completed, the electric air valve b35 at a certain sample storage cylinder 36 is opened. After 5 is opened, the pump plug 8 carrying the gas sample is driven by the transmission screw 9 to a specified stroke, and then the gas inside the sampling chamber is fully discharged into the sample storage cylinder 36. After the specified time of sample injection into the sample storage cylinder 36, the electric air valve b35 is closed. Subsequently, the indexing cylinder 5 is driven by the second motor 4 to rotate 90° clockwise again. After the indexing cylinder 5 has completed its movement, the axial flow exhaust fan is turned on, and then the residual gas sample inside the sampling chamber 6 and the indexing cylinder 5 is fully emptied in preparation for the next gas sample extraction operation.

[0067] SS003, Periodic Acquisition: In the periodic acquisition mode, the carbon verification data acquisition device repeats the SS002 step at a set interval. During each carbon verification operation, an empty sample storage cylinder 36 is updated for gas sample storage.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.

An electric air valve a (34) is fixedly installed at the tail end of the sampling tube (33). A set of connectors arranged in a linear array are installed on the bottom surface of the sampling tube (33). An electric air valve b (35) is installed inside each connector. A sample storage tube (36) is threaded to the other end of each connector. A sampling valve (37) is fixedly installed at the bottom end of the sample storage tube (36).

6. The carbon verification data acquisition device according to claim 1, characterized in that: The exhaust gas discharge assembly includes an exhaust gas pipe (38) that is fixedly connected to the collection cylinder (2). A one-way air outlet valve (39) is fixedly installed at the connection between the exhaust gas pipe (38) and the collection cylinder (2). An axial flow exhaust fan is installed inside the exhaust gas pipe (38).

7. The carbon verification data acquisition device according to claim 6, characterized in that: The axes of the exhaust pipe (38), the collection chamber (6), and the purification through hole (7), as well as the air inlet axis of the sample inlet pipe (3), are all perpendicular to the rotation axis of the rotary cylinder (5).

8. The data acquisition method of the carbon verification data acquisition device according to any one of claims 1-7, characterized in that, Includes the following steps: SS001, Deployment: Before the data collection operation, deploy this carbon verification data collection device at the designated spatial collection location. After deployment, the carbon emission analyzer (12) connects to the external remote data receiving terminal in real time via wireless signal transmission. SS002, Data Acquisition. During data acquisition, the first motor (15) and the axial flow air purifier (11) continuously output speed. When the axial flow air purifier (11) is working, it exhausts air away from the carbon emission analyzer (12). In the initial mode, under the driving action of the lifting push rod (32), the transmission bevel gear ring (31) and the passive bevel gear (10) disengage. In the initial mode, the two pump plugs (8) move fully outward under the driving action of the transmission screw (9), thereby allowing the gas inside the acquisition chamber (6) to be fully discharged. During acquisition, a certain acquisition chamber... (6) When the sampling chamber (6) is directly facing the sample inlet tube (3), under the driving action of the lifting push rod (32), the transmission bevel gear ring (31) contacts the passive bevel gear (10). After the transmission bevel gear ring (31) and the passive bevel gear (10) have been in contact for a specified time, the lifting push rod (32) automatically resets to the initial position, thereby causing the transmission bevel gear ring (31) to disengage from the passive bevel gear (10). During the driving cycle of the transmission screw (9), the pump plug (8) extracts the carbon nucleus gas sample to be collected from the sample inlet tube (3). After sufficient gas sample is extracted from the cavity (6), the indexing cylinder (5) is driven clockwise by the second motor (4) to rotate 90°. The sampling cavity (6) with the gas sample is connected to the carbon emission analyzer (12). The carbon emission analyzer (12) then performs carbon verification and carbon analysis on the gas sample inside the sampling cavity (6). When it is necessary to store the gas sample, the indexing cylinder (5) is driven clockwise by the second motor (4) to rotate 90° again. After the rotation is completed, the electric air valve b (35) at a certain storage cylinder (36) is opened. 5) After opening, the pump plug (8) with the gas sample is driven by the transmission screw (9) to a specified stroke, and then the gas inside the collection chamber (6) is fully discharged into the sample storage cylinder (36). After the sample storage cylinder (36) has been injected for a specified time, the electric air valve b (35) is closed. Then, the indexing cylinder (5) is driven by the second motor (4) to rotate 90° clockwise again. After the indexing cylinder (5) has finished moving, the axial flow exhaust fan is turned on, and then the residual gas sample inside the collection chamber (6) and the indexing cylinder (5) is fully discharged in preparation for the next gas sample extraction operation. SS003, Periodic Acquisition: In the periodic acquisition mode, the carbon verification data acquisition device repeats the SS002 steps at a set interval. During each carbon verification operation, an empty sample storage cylinder (36) is updated to store the gas sample.
