Description

Technical Field

[0001] The present invention belongs to the technical field of carbon dioxide detection, and specifically relates to a carbon emission detection system. Background Art

[0002] As the global warming situation becomes increasingly severe, countries around the world are paying more and more attention to the issue of greenhouse gas emissions. In order to achieve the goal of energy conservation and emission reduction, all walks of life are taking active actions. As the main dispatching and application party of energy, the power system is in full swing in the research of carbon emission monitoring and management. Substations are key nodes and main components of the power system. It is very necessary to sort out their carbon emission footprint throughout their life cycle, and combine them with advanced monitoring technologies and management methods to form a systematic carbon emission assessment, emission reduction strategy and follow-up guidance.

[0003] The core principle of the carbon emission detector is based on infrared spectroscopy and chemical oxidation. Infrared spectroscopy uses the absorption characteristics of different gases to infrared light to identify and quantify gas components, while chemical oxidation determines the content of organic carbon by measuring the amount of carbon dioxide generated. Existing substation carbon emission detection usually uses exposure to the outside world to detect carbon emissions, which not only causes great damage to the detection device and is easily affected by cavitation, but also the detection data is relatively inaccurate. Because the outside air is affected by wind, the wind will cause uneven flow and distribution of gas, affecting the absorption and scattering of light. When infrared light is irradiated on carbon dioxide, the infrared light detected by the detector will have errors. Under normal circumstances, air samples are taken manually and then taken indoors for testing. However, manual sampling and transportation of samples introduce significant time delays, which means that the test results may not reflect the current carbon emissions status. Manual sampling is a labor-intensive process that requires dedicated personnel, increasing the complexity of the operation and human resource costs. Manual sampling cannot achieve continuous monitoring and therefore cannot capture rapid changes or peak emissions in a short period of time. Samples may be affected by environmental factors such as temperature and humidity changes during the transfer from the sampling point to the laboratory, which may change the characteristics of the sample. The cost of manual sampling and testing is usually higher than that of automated continuous monitoring systems, especially when frequent monitoring is required. At the same time, manual sampling may not provide complete data records, which is not conducive to long-term environmental monitoring and trend analysis. Summary of the invention

[0006] Furthermore, the carbon emission detection component includes an infrared light emitter and a detector which are arranged opposite to each other; the infrared light emitter is installed on the air pressure plate, and the detector is installed on the side wall of the detection chamber which is opposite to the air pressure plate.

[0009] Furthermore, the air extraction pipe is arranged on a side wall of the detection chamber opposite to the air pressure plate, and the plug assembly includes a plug arranged opposite to the air extraction pipe, and the plug is connected to the air pressure plate by a compression spring.

[0010] Furthermore, the plug assembly also includes a plug control mechanism for controlling the plug to move toward or away from the air extraction pipe to block or open the air extraction pipe.

[0011] Furthermore, the plug control mechanism includes a transmission shaft and a second screw, and the transmission shaft is connected to the output shaft of the motor; a second telescopic section that can be extended and retracted along the axial direction is provided between the transmission shaft and the second screw, and a magnetic block for generating a magnetic attraction on the plug is provided at one end of the second screw facing away from the second telescopic section; a second screw hole that cooperates with the thread of the second screw is provided on the fixed plate.

[0012] Furthermore, the second screw rod (192) and the first screw rod (4) are parallel to each other and move in the same direction relative to the fixed plate (15); the speed at which the second screw rod (192) moves relative to the fixed plate (15) is greater than the speed at which the first screw rod (4) moves relative to the fixed plate (15); and the output shaft of the motor and the transmission shaft are connected to each other by a gear transmission mechanism, a belt transmission mechanism or a chain transmission mechanism.

[0013] Furthermore, a lubrication system for lubricating the first screw and / or the second screw is provided in the functional chamber.

[0014] Furthermore, the lubrication system includes an elastic air pipe, an air cavity connected to the air pipe through a first pipe, and a lubrication cavity connected to the air cavity through a second pipe. The air pipe is arranged opposite to the magnetic block, and the lubrication cavity is provided with a nozzle facing the first screw and / or the second screw; a first one-way valve allowing outside air to enter is provided on the air inlet of the air pipe, and a second one-way valve allowing gas in the air pipe to enter the air cavity is provided on the first pipe; and a pressure valve is provided on the second pipe for entering the lubrication cavity after the air pressure in the air cavity reaches a set pressure value.

[0015] The beneficial effects of the present invention are: The carbon emission detection system of the present invention is provided with an air pressure plate in the detection box, and the air pressure plate divides the detection box into a detection chamber and a functional chamber. In this way, the air pressure plate is driven to move in the detection box by a moving driving mechanism of the air pressure plate, and gas exchange can be carried out between the outside world through the exhaust pipe to realize carbon emission detection. The detection process is: first, the air pressure plate is driven to move toward the side where the functional chamber is located. Since the volume of the detection chamber increases, gas can be sucked in from the outside world through the exhaust pipe, and then the carbon dioxide concentration of the sucked gas is detected by using the carbon emission detection component; after the detection is completed, the air pressure plate is driven to move toward the side where the detection chamber is located. Since the volume of the detection chamber is reduced, the gas that has completed the detection in the detection chamber can be discharged through the exhaust pipe; since the gas is sucked into the detection chamber before detection, the detection process is not affected by the flow of external air, so that the detection accuracy can be improved; in addition, the carbon emission detection component is arranged in the detection chamber, is not easily affected by cavitation, can increase the service life, and is particularly suitable for application scenarios such as substations; by controlling the reciprocating movement frequency of the air pressure plate in the detection box, the detection frequency can also be conveniently controlled.

[0016] The present invention also has the following technical effects: By setting up a plug assembly, when the detection operation is not performed, the air pressure plate is located at one end of the side where the detection chamber is located, and the magnetic block is against the air pressure plate. The magnetic attraction of the magnetic block on the plug is used to compress the spring. However, since the air pressure plate is close to the side wall where the exhaust pipe is located, the plug blocks the exhaust pipe under the driving action of the air pressure plate to prevent external gas from entering the detection chamber, so as to protect the carbon emission detection assembly. When the detection operation is performed, the air pressure plate is driven to move toward the side where the functional chamber is located. At this time, the plug is separated from the exhaust pipe under the magnetic attraction of the magnet. , so that the exhaust pipe opens to inhale gas; continue to drive the air pressure plate to move. Since the speed of the second screw is greater than the speed of the first screw, the magnetic block moves away from the air pressure plate, and the distance between the magnetic block and the plug gradually increases, resulting in a decrease in the magnetic attraction of the magnetic block on the plug. The compression spring overcomes the magnetic attraction and extends, allowing the plug to extend into the exhaust pipe and block the exhaust pipe; in this way, the interference of external gas on the gas in the detection room during carbon emission detection can be avoided, the gas in the detection room can be kept stable, and the accuracy of carbon emission detection can be further improved.

[0017] By setting up a lubrication system and through the reciprocating motion of the magnetic block during the detection process, when the magnetic block compresses the air pipe, the gas in the air pipe enters the air cavity through the second one-way valve, and the air pressure in the air cavity increases; when the air pressure in the air cavity increases to the set pressure value, the pressure valve opens, and the gas in the air cavity rushes into the lubrication cavity, carrying the lubricating oil in the lubrication cavity through the nozzle to the first screw and / or the second screw, so as to lubricate the first screw and / or the second screw, so that the moving mechanism in the functional room can maintain a lubricated state, prevent jamming, and improve the service life and reliability of the carbon emission detection system.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0021] like Figure 1-3 As shown, the carbon emission detection system of this embodiment includes a detection box 1, in which a pressure plate 16 is provided. The pressure plate 16 is tightly fitted with the inner wall of the detection box 1, and the pressure plate 16 divides the detection box 1 into a detection chamber 1a and a functional chamber 1b; the detection chamber 1a is provided with an exhaust pipe 17 connected to the outside and a carbon emission detection component for detecting the concentration of carbon dioxide; the functional chamber 1b is provided with a pressure plate moving drive mechanism for driving the pressure plate 16 to move along the inner wall of the detection box 1 to inhale or exhaust gas through the exhaust pipe 17.

[0022] Specifically, the carbon emission detection assembly of this embodiment includes an infrared light emitter 161 and a detector 18 arranged opposite to each other. Figure 1-2 As shown, the infrared light emitter 161 of this embodiment is installed on the air pressure plate 16, and the detector 18 is installed on the side wall of the detection chamber 1a opposite to the air pressure plate 16. The working principle of the carbon emission detection component is: broadband infrared light is emitted by the infrared light emitter 161, and the gas inhaled in the detection chamber 1a is passed through, and part of the infrared light is absorbed by carbon dioxide, while the remaining infrared light is received by the detector 18 after passing through the gas. The detector 18 converts the received infrared light into an electrical signal, and after signal processing, the concentration value of carbon dioxide is displayed. It has the advantages of high sensitivity, fast speed, and less interference, and is particularly suitable for online and offline carbon emission monitoring.

[0023] The pneumatic plate moving driving mechanism of this embodiment includes a motor 11 and a fixed plate 15 fixedly installed in the functional chamber 1b, the output shaft 12 of the motor 11 is connected with a first telescopic section 13 that can be telescoped along the axial direction, the first telescopic section 13 is connected with a first screw 14 that rotates synchronously with it, and the fixed plate 15 is provided with a first screw hole that is threadedly matched with the first screw 14; the first screw 14 is rotationally matched with the pneumatic plate 16. The working principle of the pneumatic plate moving driving mechanism is: the motor 11 runs, drives the first telescopic section 13 to rotate through the output shaft 12, the first telescopic section 13 drives the first screw 14 to rotate, the first screw 14 moves relative to the fixed plate 15 through the threaded matching relationship between the first screw hole on the fixed plate 15, and the first telescopic section 13 compensates the distance when the first screw 14 moves relative to the fixed plate 15 through telescopic movement; in the process of the first screw 14 moving relative to the fixed plate 15, it drives the pneumatic plate 16 to move synchronously with it, so that the volume of the detection chamber 1a can be increased or decreased. Specifically, when the volume of the detection chamber 1a increases, gas can be sucked in from the outside through the exhaust pipe 17, and then the carbon dioxide concentration in the gas can be detected through the carbon emission detection component; when the volume of the detection chamber 1a decreases, the gas in the detection chamber 1a can be discharged to the outside through the exhaust pipe 17. By controlling the direction and speed of the motor 11, the air can be extracted smoothly, the detected data can be more accurate, and the detection frequency can be controlled by adjusting the forward and reverse rotation frequency of the motor 11, so the use effect is better.

[0024] like Figure 2 As shown, the carbon emission detection system of this embodiment also includes a plug assembly for opening or blocking the exhaust pipe 17. Specifically, the exhaust pipe 17 of this embodiment is arranged on the side wall of the detection chamber 1a opposite to the air pressure plate 16. Correspondingly, the plug assembly of this embodiment includes a plug 162 arranged opposite to the exhaust pipe 17, and the plug 162 and the air pressure plate 16 are connected by a compression spring 1621. Specifically, the plug assembly of this embodiment also includes a plug control mechanism for controlling the plug 162 to move toward or away from the exhaust pipe 17 to block or open the exhaust pipe 17. As shown Figure 3As shown, the plug control mechanism of this embodiment includes a transmission shaft 194 and a second screw rod 192, and the transmission shaft 194 is connected to the output shaft 12 of the motor 11. A second telescopic section 191 that can be telescoped along the axial direction is provided between the transmission shaft 194 and the second screw rod 192, and a magnetic block 193 for generating a magnetic attraction on the plug 162 is provided at one end of the second screw rod 192 that is opposite to the second telescopic section 191. A second screw hole that is threadedly matched with the second screw rod 192 is provided on the fixed plate 15. Specifically, the second screw rod 192 is parallel to the first screw rod 14 and moves in the same direction relative to the fixed plate 15, and the speed at which the second screw rod 192 moves relative to the fixed plate 15 is greater than the speed at which the first screw rod 14 moves relative to the fixed plate 15. The relative speed of the second screw 192 and the first screw 14 can be controlled by the transmission ratio between the output shaft 12 of the motor 11 and the transmission shaft 194, or by the pitch of the second screw 192 and the first screw 14; of course, the relative speed of the second screw 192 and the first screw 14 can be controlled by combining the transmission ratio and the pitch. The output shaft 12 of the motor 11 and the transmission shaft 194 are connected by a gear transmission mechanism, a belt transmission mechanism or a chain transmission mechanism. In this embodiment, the transmission ratio between the output shaft 12 of the motor 11 and the transmission shaft is equal to 2, and the output shaft 12 of the motor 11 and the transmission shaft 194 are connected by a gear transmission mechanism. The gear transmission mechanism includes a driving gear 20 that rotates synchronously with the output shaft 12 of the motor 11 and a driven gear 19 that rotates synchronously with the transmission shaft 194, and the transmission ratio between the driving gear 20 and the driven gear 19 is equal to 2. In this embodiment, since the gear transmission mechanism only includes a driving gear 20 and a driven gear 19 that mesh with each other, the direction of rotation of the output shaft 12 of the motor 11 is opposite to the direction of rotation of the transmission shaft 194. In order to ensure that the first screw 14 and the second screw 192 move in the same axial direction, it is necessary to set the thread spiral directions of the first screw 14 and the second screw 192 in opposite directions.

[0025] Specifically, the carbon emission detection system of the present embodiment is provided with a plug assembly. When the detection operation is not performed, the air pressure plate 16 is located at one end of the side where the detection chamber 1a is located, and the magnetic block 193 is against the air pressure plate 16. The magnetic attraction of the magnetic block 193 on the plug 162 is used to compress the spring 1621. However, since the air pressure plate 16 is close to the side wall where the exhaust pipe 17 is located, the plug 162 is driven by the air pressure plate 16 to block the exhaust pipe 17, thereby preventing external gas from entering the detection chamber 1a, so as to protect the carbon emission detection assembly. When performing the detection operation, the air pressure plate 16 is driven to move toward the side where the functional chamber 1b is located. At this time, the plug 162 is separated from the exhaust pipe 17 under the action of the magnetic attraction of the magnet 193, so that the exhaust pipe 17 is opened to inhale gas; the air pressure plate 16 is continued to be driven to move. Since the moving speed of the second screw 192 is greater than the moving speed of the first screw 14, the magnet 193 moves away from the air pressure plate 16, and the distance between the magnet 193 and the plug 162 gradually increases, resulting in a decrease in the magnetic attraction of the magnet 193 on the plug 162. The compression spring 1621 overcomes the magnetic attraction and extends, so that the plug 162 extends into the exhaust pipe 17 and blocks the exhaust pipe 17; in this way, the interference of external gas on the gas in the detection chamber 1a during the carbon emission detection process can be avoided, so that the gas in the detection chamber 1a remains stable, and the accuracy of carbon emission detection can be further improved.

[0026] The functional chamber 1b of this embodiment is provided with a lubrication system for lubricating the first screw 14 and / or the second screw 192. Figure 3 As shown, the lubrication system of this embodiment includes an elastic air pipe 163, an air cavity 164 connected to the air pipe 163 through a first pipe 167, and a lubrication cavity 165 connected to the air cavity 164 through a second pipe 168. Specifically, the air pipe 163 is arranged opposite to the magnetic block 193. The air pipe 163 of this embodiment is arranged as an annular air pipe, and the lubrication cavity 165 is provided with a nozzle 166 facing the first screw 14 and / or the second screw 192. A first one-way valve that allows outside air to enter is provided on the air inlet of the air pipe 163, and a second one-way valve that allows gas in the air pipe 163 to enter the air cavity 164 is provided on the first pipe 167. A pressure valve 169 that enters the lubrication cavity 165 after the air pressure in the air cavity 164 reaches a set pressure value is provided on the second pipe 168.

[0027] By setting up a lubrication system, through the reciprocating motion of the magnetic block 193 during the detection process, when the magnetic block 193 compresses the air pipe 163, the gas in the air pipe 163 enters the air cavity 164 through the second one-way valve, and the air pressure in the air cavity 164 increases. When the air pressure in the air cavity 164 increases to the set pressure value, the pressure valve 169 opens, and the gas in the air cavity 164 rushes into the lubrication cavity 165, carrying the lubricating oil in the lubrication cavity 165 through the nozzle 166 to spray to the first screw 14 and / or the second screw 192, lubricating the first screw 14 and / or the second screw 192, so that the motion mechanism in the functional chamber 1b can maintain a lubricated state, prevent jamming, and improve the service life and reliability of the carbon emission detection system. In the example of this embodiment, a nozzle 166 facing the first screw 14 is provided on the lubrication cavity 165. Of course, in some other embodiments, a nozzle 166 facing the second screw 192 can also be provided, which will not be repeated.

[0028] Specifically, the process of using the carbon emission detection system of this embodiment to detect carbon dioxide concentration is as follows.

[0029] (1) Starting the motor 11: The motor 11 starts to run, driving the first telescopic section 13 to rotate through the output shaft 12.

[0030] (2) Extracting outside air: The first telescopic section 13 drives the first screw 14 to rotate, and the first screw 14 moves to the left through the threaded fit with the first screw hole on the fixing plate 15. The first telescopic section 13 is squeezed and shortened, driving the air pressure plate 16 to move along the inner wall of the detection box 1 toward the side (left side) where the functional chamber 1b is located, and extracting outside air through the exhaust pipe 17.

[0031] The driving gear 20 meshes with the passive gear disc 19, and the rotation of the driving gear 20 drives the passive gear disc 19 to rotate, thereby driving the second screw 192 and the second telescopic joint 191. The magnetic block 193 interacts with the plug 162 through magnetic force to control the opening and closing of the exhaust pipe 17 to maintain the stability of the gas in the detection chamber 1a.

[0032] The air pipe 163 draws gas from the outside and injects it into the air cavity 164. When the gas pressure in the air cavity 164 reaches the bearing limit of the pressure valve 169, the pressure valve 169 opens, and the gas quickly enters the lubrication cavity 165. The lubricating oil is squeezed and sprayed onto the first screw 14 and / or the second screw 192 through the nozzle 166 for lubrication.

[0033] (3) Detecting carbon emission data: The infrared light emitter 161 emits broadband infrared light. After passing through the gas, part of the infrared light is absorbed by the carbon dioxide, and the remaining infrared light passes through the gas.

[0034] The detector 18 receives the remaining infrared light and converts it into an electrical signal.

[0035] The signal processing module processes the electrical signal and displays the concentration value of carbon dioxide.

[0036] (4) Exhaust gas from the detection chamber: After the detection is completed, the motor 11 rotates in the opposite direction, driving the air pressure plate 16 to move toward the side (right side) where the detection chamber 1a is located, and exhausts the gas from the detection chamber 1a. After the gas in the detection chamber 1a is completely exhausted, the plug 162 moves with the air pressure plate 16 and is inserted into the exhaust pipe 17.

[0037] (5) Control the detection frequency: By adjusting the frequency of the forward and reverse rotation of the motor 11, the detection frequency is controlled to improve the use effect.

[0038] The carbon emission detection system of this embodiment ensures the accuracy and stability of carbon emission detection, while reducing maintenance costs and equipment losses through the lubrication system, and is particularly suitable for application scenarios such as substations.
