Description

Technical Field

[0001] This utility model relates to the field of carbon emission monitoring technology, specifically to a metering device for monitoring carbon emissions. Background Technology

[0002] Carbon emissions refer to the process by which greenhouse gas emissions enhance the greenhouse effect, leading to a rise in global temperatures. While receiving solar radiation, the Earth also radiates heat into outer space, primarily in the form of long-wave infrared radiation (3-30 micrometers). When this long-wave radiation enters the atmosphere, it is easily absorbed by gas molecules with larger molecular weights and stronger polarity. Because infrared energy is lower than molecular bond energy, the absorption process does not trigger a chemical reaction; instead, it creates a greenhouse-like insulating effect by preventing heat from escaping into space. In industrial production processes, carbon emission meters are typically used for real-time monitoring and control to effectively manage carbon emissions.

[0003] Chinese patent (authorization announcement number: CN221351389U, authorization announcement date: 2024.07.16) proposes a carbon emission meter, relating to the field of carbon emission monitoring technology. The device contains a computer connected to the meter body via a wired connection. An exhaust valve is located on the right side of the meter body, and a flow rate detector is connected to the left side of the meter body, which is also connected to the computer. The flow rate detector is connected to a connecting pipe on its left side, and an inlet valve is located inside the connecting pipe. A second bevel gear is located at the bottom of the inlet valve, meshing with a first bevel gear. The first bevel gear is connected to a rotating shaft, which is connected to a micro-motor. The top of the connecting pipe passes through the device body and connects to a regulating valve. By incorporating the flow rate detector and computer, the device can simultaneously calculate the gas flow rate while monitoring carbon dioxide levels in the gas through the connecting pipe, thus reducing the error in calculating the carbon dioxide content and other gaseous parameters.

[0004] The aforementioned carbon emission meter uses only a two-stage filter block to filter air, which has limited filtering effect on fine impurities and odors in the gas. Furthermore, the air intake structure of the aforementioned carbon emission meter relies on manually moving the connecting pipe to adjust the detection position, which has low practicality and is not suitable for long-term outdoor use. Therefore, we propose a metering device that can monitor carbon emissions. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6This utility model provides a technical solution: a metering device for monitoring carbon emissions, including a device housing 1. A carbon emission metering and monitoring instrument 9 and an air pump 10 are fixedly installed on the rear side of the device housing 1. The input end of the air pump 10 is fixedly connected to the output end of the carbon emission metering and monitoring instrument 9 through a pipe. An exhaust port 6 is opened at the bottom right side of the device housing 1. The output end of the air pump 10 is fixedly connected to the exhaust port 6 through a pipe. A fixed cylinder 16 is fixedly connected to the left side of the device housing 1. An air outlet 39 is opened at the bottom side of the fixed cylinder 16. The input end of the carbon emission metering and monitoring instrument 9 is fixedly connected to the air outlet 39 through a pipe. A filter assembly is installed inside the fixed cylinder 16. A rotating tube 11 is rotatably inserted through the top left side of the device housing 1. An air inlet assembly is installed between the rotating tube 11 and the fixed cylinder 16. A photovoltaic module is also installed on the rear side of the device housing 1.

[0022] When the carbon emission monitoring device is in operation, the air intake component allows external gas to enter the device through the rotating pipe 11. The gas is then transported to the fixed cylinder 16 through the rotating pipe 11. After being processed by the filter component in the fixed cylinder 16, the gas is discharged from the outlet 39 on the bottom side of the fixed cylinder 16 and then transported to the carbon emission metering and monitoring instrument 9 through a pipeline. After monitoring the carbon emission-related indicators of the gas, the carbon emission metering and monitoring instrument 9 delivers the gas to the air pump 10. The air pump 10 discharges the processed gas through the exhaust port 6 at the bottom right side of the equipment box 1 through a pipeline. At the same time, the photovoltaic module on the rear side of the equipment box 1 provides energy support for the operation of the device.

[0023] The filter assembly includes a first insert plate 29, a second insert plate 30 fixedly connected to the middle right side of the first insert plate 29, a first filter cartridge 32 and a second filter cartridge 33 fixedly connected to the middle right side of the second insert plate 30, the second filter cartridge 33 being sleeved on the outside of the first filter cartridge 32, an activated carbon adsorption layer 34 being provided between the first filter cartridge 32 and the second filter cartridge 33, a sealing sleeve 35 being inserted between the right ends of the first filter cartridge 32 and the second filter cartridge 33, a connecting tube 38 being fixedly inserted through the right side of the fixed cylinder 16, the sealing sleeve 35 being sleeved on the connecting tube 38, and a quick-release mechanism being provided between the first insert plate 29 and the fixed cylinder 16.

[0024] The quick-release mechanism includes two sets of limiting plates 31, which are fixedly connected to the upper and lower sides of the second insert plate 30 respectively. The inner wall of the left end of the fixing cylinder 16 has a slot 18, and the second insert plate 30 is inserted into the slot 18. A sealing gasket 36 is provided between the right side of the second insert plate 30 and the left side of the second slot 18. The inner wall of the left end of the second slot 18 has a slot 17, and the first insert plate 29 is inserted into the slot 17. The front and rear sides of the right wall of the first slot 17 have sliding grooves 20. The front and rear sides of the side wall of the second slot 18 have sliding grooves 19. The first sliding groove 19 communicates with the second sliding groove 20, and the limiting plate 31 is slidably connected to the sliding groove 19. The front and rear sides of the left side of the first insert plate 29 also have pull grooves 37.

[0025] When the filter assembly is working, gas enters through the connecting pipe 38, passes through the sealing sleeve 35, and enters the interior of filter cartridge 32. Filtration and adsorption are achieved through filter cartridge 32, filter cartridge 33, and the activated carbon adsorption layer 34 between filter cartridges 32 and 33. When disassembly and maintenance are required, insert plate 29 is rotated via the pull groove 37 on the left and front / rear sides of insert plate 29, thereby rotating insert plate 30. This causes the upper and lower limiting plates 31 to slide along the sliding groove 19 until the two sets of limiting plates 31 are aligned with the two sets of sliding grooves 20. At this point, insert plate 29 is pulled via the pull groove 37, causing the two sets of limiting plates 31 to slide along the sliding groove 19. Plate 31 disengages from the two sets of sliding grooves 20, thereby causing the insert plate 29 to disengage from slot 17 and the insert plate 30 to disengage from slot 18, allowing the filter cartridge 32, filter cartridge 33 and activated carbon adsorption layer 34 to be removed together for replacement and maintenance. During installation, insert plate 29 is inserted into slot 17, causing insert plate 30 to be inserted into slot 18. The limiting plate 31 slides into sliding groove 19 through sliding groove 20. Then, insert plate 29 is rotated so that the limiting plate 31 slides in sliding groove 19 to complete the fixation. The sealing gasket 36 between the right side of insert plate 30 and the left side of slot 18 ensures the sealing of the connection.

[0026] The air intake assembly includes a rotary joint 15. A fixed plate 14 is fixedly connected to the top of the equipment housing 1. The rotary joint 15 is mounted on the fixed plate 14. The bottom output end of the rotating pipe 11 is fixedly connected to the input end of the rotary joint 15. The output end of the rotary joint 15 is fixedly connected to the right end of the connecting pipe 38 through a pipe. A threaded sleeve 22 is fixedly fitted to the top of the rotating pipe 11. An air intake pipe 5 is threadedly inserted into the threaded sleeve 22. A sealing gasket 25 is provided between the bottom side of the air intake pipe 5 and the top side of the rotating pipe 11. A flared mouth 23 is fixedly connected to the input end of the air intake pipe 5. A filter plate 24 is fixedly connected inside the flared mouth 23. A rotating mechanism for driving the rotating pipe 11 to rotate is installed on the top of the equipment housing 1.

[0027] The rotating mechanism includes a drive motor 12, which is fixedly installed on the top side inside the equipment housing 1. Both the output shaft of the drive motor 12 and the rotating tube 11 are fixedly sleeved with bevel gears 13, and the two sets of bevel gears 13 mesh with each other.

[0028] When the intake assembly is working, external gas enters through the flared end 23 of the intake pipe 5. The filter plate 24 inside the flared end 23 performs preliminary filtration of the gas. The filtered gas is then transmitted to the rotating pipe 11 through the intake pipe 5. The intake pipe 5 and the rotating pipe 11 are connected by a threaded sleeve 22. The sealing gasket 25 between them ensures the airtightness of the gas transmission. When the drive motor 12 is started, its output shaft drives the bevel gear 13 on it to rotate. Since the two sets of bevel gears 13 mesh with each other, the rotating pipe 11 rotates synchronously with the other set of bevel gears 13. When the rotating pipe 11 rotates, its bottom output end is connected to the connecting pipe 38 through the rotary joint 15. The gas is transmitted to the right end of the connecting pipe 38 through the rotating pipe 11 and the rotary joint 15, completing the gas delivery.

[0029] The photovoltaic module includes a solar panel 27, which is hinged to the top rear side of the equipment housing 1. A mounting groove 26 is provided on the rear side of the equipment housing 1. An electric push rod 28 is hinged to the bottom side of the inside of the mounting groove 26. The output shaft end of the electric push rod 28 is hinged to the middle front side of the solar panel 27.

[0030] When the photovoltaic module is working, the solar panel 27 is hinged to the top rear side of the equipment box 1. The absorbed solar energy is converted into electrical energy and stored in the battery 21 to provide power for the operation of the device. When the output shaft of the electric push rod 28 extends or retracts, it pushes the solar panel 27 to rotate around the hinge point to adapt to different light angles and improve the solar energy absorption efficiency.

[0031] The equipment housing 1 is hinged to the front of the door 2, and the door 2 is equipped with a display screen 3. The door 2 on the front of the equipment housing 1 can be opened and closed around the hinge point, which facilitates the inspection or operation of the internal components of the housing. The display screen 3 on the door 2 is used to display relevant data of carbon emission measurement and monitoring, so that users can intuitively view the monitoring results.

[0032] An audible and visual alarm 4 is installed on the top right side of the equipment housing 1. The audible and visual alarm 4 is linked to the internal monitoring system of the device. When the carbon emission exceeds the standard or the equipment malfunctions, the audible and visual alarm 4 is activated and issues an alarm through sound and light signals to prompt the user to take timely action.

[0033] A storage battery 21 is installed on the bottom side of the inside of the equipment housing 1. The storage battery 21 can store electrical energy and provide power support for the various components of the device.

[0034] Mounting plates 7 are fixedly connected to the bottom left and right sides of the equipment housing 1. Two sets of mounting holes 8 are opened through the mounting plates 7. The mounting plates 7 are used to support the entire device. The two sets of mounting holes 8 through the mounting plates 7 can be used with bolts and other fasteners to fix the device to the ground, brackets and other installation positions.

[0035] Working principle: When the metering device that monitors carbon emissions is in operation, external gas enters through the flared end 23 of the inlet pipe 5. The filter plate 24 inside the flared end 23 performs preliminary filtration of the gas. The filtered gas is then transmitted to the rotating pipe 11 through the inlet pipe 5. The inlet pipe 5 and the rotating pipe 11 are connected by a threaded sleeve 22. The sealing gasket 25 between the two ensures the airtightness of the gas transmission. When the drive motor 12 is started, its output shaft drives the bevel gear 13 on it to rotate. Since the two sets of bevel gears 13 mesh with each other, the rotating pipe 11 rotates synchronously with the other set of bevel gears 13. When the rotating pipe 11 rotates, its bottom output end is connected to the connecting pipe 38 through the rotary joint 15. The gas is transmitted to the right end of the connecting pipe 38 through the rotating pipe 11 and the rotary joint 15, thus completing the gas delivery. Gas enters through the connecting pipe 38, passes through the sealing sleeve 35, and enters the interior of filter cartridge 32. Filtration and adsorption are achieved through filter cartridge 32, filter cartridge 33, and the activated carbon adsorption layer 34 between filter cartridge 32 and filter cartridge 33. When disassembly and maintenance are required, insert plate 29 is rotated via the pull groove 37 on the left front and rear sides of insert plate 29, thereby rotating insert plate 30. This causes the upper and lower limiting plates 31 to slide along slide groove 19 until the two sets of limiting plates 31 are aligned with the two sets of slide grooves 20. At this point, insert plate 29 is pulled via the pull groove 37, causing the two sets of limiting plates 31 to disengage from the two sets of slide grooves 20. This causes insert plate 29 to disengage from slot 17, and insert plate 30 to disengage from slot 28, allowing filter cartridge 32, filter cartridge 33, and activated carbon adsorption layer 34 to be removed together for replacement and maintenance. The filtered gas is discharged from the outlet 39 on the bottom side of the fixed cylinder 16, and then transported to the carbon emission metering and monitoring instrument 9 through the pipeline. After the carbon emission metering and monitoring instrument 9 monitors the carbon emission-related indicators of the gas, it transports the gas to the air pump 10. The air pump 10 discharges the treated gas through the exhaust port 6 at the bottom right side of the equipment box 1 through the pipeline.
