Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission detection, and in particular to a local space air collection device for carbon emissions. Background Art

[0002] Carbon emissions, in essence, generally refer to greenhouse gas emissions resulting from various human activities. These greenhouse gases, such as carbon dioxide, continue to accumulate in the atmosphere, creating a greenhouse-like effect known as the greenhouse effect. Among the many sources of carbon emissions, high-carbon-emitting enterprises, factories, and nuclear power plants are of particular concern. For example, high-carbon-emitting enterprises and factories often consume large quantities of fossil fuels, such as coal and oil, during their production and operations, resulting in large amounts of greenhouse gas emissions, including carbon dioxide. While nuclear power plants do not directly emit carbon dioxide during operation, they may also generate a certain amount of greenhouse gas emissions during the mining, processing, and transportation of nuclear fuel, as well as the disposal of nuclear waste. Furthermore, in certain special circumstances, the operation of nuclear power plants' energy conversion and auxiliary systems may also indirectly involve carbon emissions.

[0003] To effectively control carbon emissions and prevent these companies from excessively emitting greenhouse gases, environmental authorities shoulder the important responsibility of overseeing and monitoring their carbon emissions. To achieve accurate and effective monitoring, environmental authorities employ specialized air sampling devices to monitor carbon emissions.

[0004] For example, a dynamic detection device for carbon emission factors based on buildings with the publication (announcement) number CN117607361A includes a detection platform, an exhaust pipe outlet, a negative pressure switch for controlling the opening and closing of the exhaust pipe outlet, a detection box, a connecting mechanism, a cantilever, a fixing bolt, an adjustment component, a fixing sleeve and a fixing mechanism. The detection platform is arranged on the side of the building close to the doors and windows, the exhaust pipe outlet is arranged at the four corners of the detection platform, and a power source for controlling the exhaust of the exhaust pipe outlet is provided inside the detection platform.

[0005] Based on the above, it can be seen that the following technical problems exist in the existing technology: Although the above-mentioned existing technology can detect carbon emissions during use, since the concentration of carbon dioxide in the air is different at different times, a single collection can easily cause large errors in the detection results. The existing technology is difficult to collect air in continuous intervals to reduce errors. At the same time, when the concentration of carbon dioxide is too high in a short period of time, it is not convenient to issue an early warning. For this reason, we propose a local space air collection device for carbon emissions. Summary of the Invention

In the initial state, the second blocking ball 16 is in contact with the second inclined notch 17, and the first blocking ball 13 is in contact with the first inclined notch 14.

The pump 23 is started, and the input end of the pump 23 transmits the air groove to the return pipe 25 through the air pipe 24, and finally is injected into the purple litmus solution again through the return pipe 25 to increase the dissolution rate.

[0028] A monitoring mechanism is installed between the supporting seat 2 and the collecting tube 3, and the monitoring mechanism includes a acid-base tester 20, an alarm 21 and a controller 22.

The controller 22 and the L-shaped top frame are fixed on one side of the supporting seat 2, and a camera is fixed on the top of the L-shaped top frame. The alarm 21 is fixed on one side of the L-shaped top frame. The controller 22 is electrically connected to the alarm 21, the camera and the acid-base tester 20 through a wire. By presetting the detection threshold of the acid-base tester 20, when the pH value of the solution in the collecting tube 3 exceeds the threshold, the controller 22 controls the alarm 21 to start an alarm reminder.

[0029] An auxiliary mechanism is assembled between the conveying cavity 4 and the transmission draw rod 5, and the auxiliary mechanism includes an L-shaped mounting seat 26, a mounting T-shaped plate 27, a motor 28, an output spindle 29, a cam seat 30, an L-shaped mounting frame 31, a force arm 32 and a rebound spring 33. An L-shaped mounting seat 26 is fixed at one end of the conveying cavity 4, and two mounting T-shaped plates 27 are fixed on the top of one side of the L-shaped mounting seat 26. An output spindle 29 is rotatably connected between the two mounting T-shaped plates 27. A motor 28 is fixed on one side of one of the mounting T-shaped plates 27. The output end of the motor 28 is fixed to the output spindle 29, and the outer side of the output spindle 29 slides. It is connected to a cam seat 30, and one side of the L-shaped mounting seat 26 is rotatably connected to an L-shaped mounting frame 31. The bottom of the cam seat 30 is in contact with one end of the L-shaped mounting frame 31. A rebound spring 33 is fixed to the side of the L-shaped mounting frame 31 close to the L-shaped mounting seat 26. One end of the rebound spring 33 is fixed to the L-shaped mounting seat 26. The bottom of the L-shaped mounting frame 31 is rotatably connected to a force arm 32, and one end of the force arm 32 is rotatably connected to the transmission draw rod 5. A plurality of raised circles of different sizes are evenly distributed and fixed on the outside of the cam seat 30. The raised circles are all in contact with one end of the L-shaped mounting frame 31, and the raised circles correspond to the annular recesses one by one.

[0030] Example 2 Further optimize Example 1, specifically, as Figure 8As shown, the auxiliary mechanism also includes a linear shaft 34, an L-shaped connecting frame 35, a rotating shaft 36, a threaded rod 37 and a plug column 38. The linear shaft 34 is fixed between the two mounting T-plates 27 and at a position deviated from the output main shaft 29. The outer side of the linear shaft 34 is slidably connected to the L-shaped connecting frame 35. One end of the L-shaped connecting frame 35 is rotatably connected to one end of the cam seat 30. The bottom of the L-shaped connecting frame 35 is rotatably connected to the rotating shaft 36. A vertical cavity is provided on the inner side of the L-shaped connecting frame 35 and close to the rotating shaft 36. The top of the rotating shaft 36 passes through the vertical cavity and is fixed with a threaded rod 37. The top of the threaded rod 37 is threadedly connected to the plug column 38. The plug column 38 slides with the vertical cavity Dynamic connection, a rectangular protrusion is fixed on the outside of the plug post 38, and the rectangular protrusion is slidably connected to the vertical cavity. A plurality of annular recesses are evenly distributed on the outside of the linear shaft 34, and the annular recesses are transitionally matched with the top of the plug post 38. When it is necessary to adjust the pushing amplitude of the cam seat 30 on the L-shaped mounting frame 31, the rotating shaft 36 is rotated so that the rotating shaft 36 drives the threaded rod 37 to rotate, thereby separating the plug post 38 from the annular recess, and then the L-shaped connecting frame 35 is moved so that the cam seat 30 driven by the L-shaped connecting frame 35 moves along the outside of the output main shaft 29. When it is adjusted to the specified position, the rotating shaft 36 is screwed in the opposite direction until the plug post 38 is connected to the corresponding annular recess.

[0031] From the above, we can know that: The present invention addresses the following technical issues: While existing technologies can detect carbon emissions during use, single collections can easily lead to large errors in detection results due to the varying concentrations of carbon dioxide in the air at different times. It is difficult to collect air over consecutive time intervals to reduce errors, and it is also difficult to issue warnings when the concentration of carbon dioxide is too high within a short period of time. The present invention adopts the technical solutions of the above-mentioned embodiments. Furthermore, the implementation process of the above-mentioned technical solutions is as follows: During use, by setting multiple devices at different positions for detection and sampling, and then starting the motor 28, the output end of the motor 28 drives the output main shaft 29 to rotate, and then the output main shaft 29 drives the cam seat 30 to rotate, so that a raised circle of the cam seat 30 gradually moves away from the L-shaped mounting bracket 31. At this time, the rebound spring 33 rebounds and resets, so that the L-shaped mounting bracket 31 rotates along the connection with the L-shaped mounting bracket 26, and at the same time, the L-shaped mounting bracket 31 pulls the force arm 32 and the transmission draw rod 5 to move, so that negative air pressure is generated in the inner cavity 6, and the inner cavity 6, the connecting cavity 8 and the air inlet cavity 7 are connected, so that the first The blocking ball 13 presses the first return spring 12 downward to contract, causing the first blocking ball 13 to be temporarily separated from the first inclined notch 14. At this time, external air enters the connecting cavity 8 through the air inlet cavity 7, passes through the guide cavity 11 and the exhaust port 18, and as the raised ring gradually approaches the L-shaped mounting frame 31, the air is finally discharged into the collecting tube 3 through the exhaust cavity 9 and the connecting elbow 19. The air contacts the purple litmus solution to form a red color. The image is captured by the camera and transmitted to the controller 22 for analysis and detection. If the color depth exceeds the preset color depth, the controller 22 controls the alarm 21 to activate, alerting the staff and making a preliminary judgment on the degree of carbon emissions. The raised ring pushes one end of the L-shaped mounting frame 31 at continuous intervals, causing the transmission draw rod 5 to drive the piston 10 to continuously reciprocate within the inner cavity 6, thereby achieving continuous interval sampling of air to simulate multiple changes in the concentration of carbon dioxide in the air at different times to reduce the final detection error. Finally, the pH value of the purple litmus solution is measured by the acid-base tester 20 to secondary determine the degree of carbon emissions in the air.

[0032] Through the above configuration, this application can certainly solve the above technical problems and achieve the following technical effects: 1. The structural design of the gas collection mechanism and the circulation mechanism of the present invention makes it easy for the device to transport air to the collection cylinder 3, which can accelerate the dissolution of carbon dioxide into the purple litmus solution, facilitate the observation of the color change of the purple litmus solution, and improve the efficiency of the device.

[0033] 2. The present invention uses the structural design of the monitoring mechanism and the auxiliary mechanism to enable the device to collect air in continuous intervals, forming multiple sampling, and can issue an early warning when the concentration of carbon dioxide is too high in a short period of time.
