[0002] As a core component of the metering device, the detection accuracy and stability of the carbon dioxide sensor directly affect the reliability of the carbon emission data.

[0003] However, dust and particulate matter in the ambient air are easy to enter the detection cavity with the airflow, which not only pollutes the sensor probe, but also may block the air path, resulting in detection errors or even equipment failure. Therefore, efficient dust removal design at the air inlet end is the key to ensuring long-term stable operation of the device. The traditional scheme relies on fixed filter screens to intercept impurities, but the filter screens need to be manually disassembled and cleaned after being blocked. In particular, in high-dust scenes such as chemical industry and metallurgy, frequent maintenance not only increases the operation and maintenance cost, but also may cause data interruption due to shutdown, which is difficult to meet the real-time monitoring demand.

[0027] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0028] According to one embodiment of the present invention, Figures 1-7 A carbon emissions measurement and analysis device is shown. It includes a carbon emissions detector 1, which is equipped with a carbon dioxide sensor 2. The carbon dioxide sensor 2 is used to accurately detect the carbon dioxide content in the environment, providing basic data for carbon emissions measurement and analysis. A diaphragm air pump 3 is located below the carbon dioxide sensor 2. The diaphragm air pump 3 provides the power for gas flow, allowing external air to enter the device and pass through the carbon dioxide sensor 2 for detection.

[0029] The driving motor 6 is arranged above the diaphragm air pump 3 and serves as a power source to provide power for the operation of the diaphragm air pump 3. The output shaft of the driving motor 6 is rotationally connected with an eccentric wheel 8, which functions to convert the circular motion of the driving motor 6 into reciprocating linear motion to drive the diaphragm of the diaphragm air pump 3. The upper and lower sides of the eccentric wheel 8 are respectively rotationally connected with a first counterweight 7 and a second counterweight 13, which are fixedly connected with the output shaft of the driving motor 6. The first counterweight 7 and the second counterweight 13 can balance the centrifugal force generated during the rotation of the eccentric wheel 8, reduce the vibration and noise of the device, and improve the stability and reliability of the device.

[0030] The eccentric wheel 8 is rotationally connected with a first push-pull rod 9 on one side through a rotating shaft, and the other end of the first push-pull rod 9 is rotationally connected with a first diaphragm 10 through a rotating shaft, which is fixedly installed between the diaphragm air pump 3 and the air inlet pipe 4. The eccentric wheel 8 is rotationally connected with a second push-pull rod 11 on the other side through a rotating shaft, and one end of the second push-pull rod 11 is rotationally connected with a second diaphragm 12 through a rotating shaft, which is fixedly installed between the diaphragm air pump 3 and the air outlet pipe 5. When the driving motor 6 drives the eccentric wheel 8 to rotate, the eccentric wheel 8 pushes the first diaphragm 10 and the second diaphragm 12 to reciprocate through the first push-pull rod 9 and the second push-pull rod 11, respectively, thereby realizing the air suction and air exhaust functions of the diaphragm air pump 3.

[0031] The diaphragm air pump 3 is connected with the air inlet pipe 4 at one end and the air outlet pipe 5 at the other end, and the air inlet pipe 4 and the air outlet pipe 5 are respectively connected with the air inlet end and the air outlet end of the carbon dioxide sensor 2. The lower end of the air inlet pipe 4 is provided with a first one-way valve 402, and the upper end of the air inlet pipe 4 is provided with a second one-way valve 403, both of which are upwardly open. The lower end of the air outlet pipe 5 is provided with a third one-way valve 502, and the upper end of the air outlet pipe 5 is provided with a fourth one-way valve 503, both of which are downwardly open. The arrangement of the first one-way valve 402, the second one-way valve 403, the third one-way valve 502, and the fourth one-way valve 503 can ensure the one-way flow of gas in the air inlet pipe 4 and the air outlet pipe 5, prevent backflow of gas, and improve the working efficiency and reliability of the diaphragm air pump 3.

[0032] The lower end of the air inlet pipe 4 is fixedly connected with a first conical port 401, and the lower end of the air outlet pipe 5 is fixedly connected with a second conical port 501. The carbon emission detector 1 is provided below with an air inlet 101 and an air outlet 102, the first conical port 401 is opposite to the air inlet 101, and the second conical port 501 is opposite to the air outlet 102. The design of the first conical port 401 and the second conical port 501 can make the gas enter and exit the device more smoothly, reducing the resistance of gas flow.

[0033] The diaphragm air pump 3 is drivenly connected with a linkage shaft 14, and the linkage shaft 14 is fixedly connected with the second counterweight 13. In this way, the driving motor 6 drives the eccentric wheel 8 to rotate, and also drives the linkage shaft 14 to rotate through the second counterweight 13. The linkage shaft 14 is rotatably connected with a reversing shaft 16 through a magnetic coupling 15. The magnetic coupling 15 comprises first magnets 1501 and second magnets 1502. The lower end of the linkage shaft 14 is inserted into the reversing shaft 16, and the lower end of the linkage shaft 14 is fixedly connected with the first magnets 1501. The inner side of the reversing shaft 16 is fixedly connected with the second magnets 1502. The first magnets 1501 and the second magnets 1502 are both provided with two or more than two, and the number of the first magnets 1501 and the second magnets 1502 is consistent. The first magnets 1501 and the second magnets 1502 are both annular and uniformly distributed. The magnetic pole directions of adjacent first magnets 1501 are opposite, and the magnetic pole directions of adjacent second magnets 1502 are opposite. The magnetic coupling 15 can realize non-contact transmission between the linkage shaft 14 and the reversing shaft 16, avoid the wear and failure that may occur in the traditional mechanical transmission mode, and improve the reliability and stability of the transmission.

[0034] The reversing shaft 16 is fixedly connected with a reversing rotating disc 17 at the lower end. The reversing rotating disc 17 is provided with a first filter screen 18 and a second filter screen 19. The first filter screen 18 is located between the first conical port 401 and the air inlet 101, and the second filter screen 19 is located between the second conical port 501 and the air outlet 102. The first filter screen 18 and the second filter screen 19 filter the air entering the device to remove dust and impurities, preventing damage to the carbon dioxide sensor 2.

[0035] The reversing locking mechanism 20 is arranged on one side of the first conical port 401, and is used for limiting the rotation of the reversing shaft 16, and the reversing locking mechanism 20 releases the locking of the reversing shaft 16 when the first filter screen 18 is blocked. The reversing locking mechanism 20 comprises a piston pipe 2001 fixedly connected on one side of the first conical port 401 and in communication with the first conical port 401, a limiting piston 2002 arranged in the piston pipe 2001, a spring retaining ring 2003 fixedly connected in the piston pipe 2001, a reset spring 2004 arranged between the spring retaining ring 2003 and the limiting piston 2002, and a triangular wedge block 2005 fixedly connected at one end of the limiting piston 2002. The corresponding position of the reversing shaft 16 is provided with a first triangular groove 1601 and a second triangular groove 1602, and the triangular wedge block 2005 is mutually embedded with the first triangular groove 1601. The spring retaining ring 2003 is fixedly connected with the piston pipe 2001 through threads, and the position of the spring retaining ring 2003 is adjusted through threads, so that the compression degree of the reset spring 2004 can be adjusted, and then the elastic force of the reset spring 2004 is adjusted, so that the pressure required for pulling the limiting piston 2002 is adjusted, and then the degree of filter screen blockage that triggers the reversing locking mechanism 20 can be preset. The first triangular groove 1601 and the second triangular groove 1602 are 180° apart, and the first triangular groove 1601 and the second triangular groove 1602 correspond to the first filter screen 18 and the second filter screen 19 respectively.

[0036] The working principle of the present application is as follows: when the device is normally running, the driving motor 6 drives the eccentric wheel 8 to rotate, and the eccentric wheel 8 pushes the first diaphragm 10 and the second diaphragm 12 to do reciprocating motion through the first push-pull rod 9 and the second push-pull rod 11 respectively, so that the diaphragm air pump 3 generates the functions of inhaling and exhaling. The external air enters the carbon dioxide sensor 2 for detection through the air inlet 101, the first filter screen 18, the first conical port 401 and the air inlet pipe 4, and the detected gas is discharged from the device through the air outlet 102, the second filter screen 19, the second conical port 501 and the air outlet pipe 5.

[0037] In this process, the first filter screen 18 filters the air entering the device, and over time, the first filter screen 18 will gradually be clogged with dust and impurities. When the first filter screen 18 is clogged, it becomes difficult for the diaphragm air pump 3 to draw air from the first conical port 401, causing the air pressure in the first conical port 401 to decrease. Since the piston tube 2001 is in communication with the first conical port 401, the air pressure in the piston tube 2001 will also decrease, causing the limit piston 2002 to move under the action of the air pressure difference and compress the return spring 2004, thereby causing the triangular wedge 2005 to disengage from the first triangular groove 1601. At this time, the locking of the reversing shaft 16 is released, and the drive motor 6 drives the reversing shaft 16 to rotate through the linkage shaft 14 and the magnetic coupling 15, thereby driving the reversing rotating disc 17 to rotate. When the reversing rotating disc 17 rotates exactly 180 degrees, the triangular wedge 2005 will again engage the second triangular groove 1602, causing the first filter screen 18 and the second filter screen 19 to exchange positions. In this way, the clogged first filter screen 18 is exchanged to below the second conical port 501, and since the second conical port 501 is the air outlet, the airflow will blow back and clean the clogged first filter screen 18, thereby cleaning the blockage. When the second filter screen 19 is clogged, the above process will be repeated to automatically exchange back, so that manual cleaning is not required.

[0038] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the present application, and these modifications and changes should all be within the protection scope of the present application.
