Description

Technical Field

[0001] This utility model belongs to the field of carbon emission monitoring technology, and specifically relates to a highway carbon emission monitoring device. Background Technology

[0002] Highway carbon emission monitoring devices are core equipment for low-carbon governance in the transportation sector. They collect and analyze the concentration of greenhouse gases such as CO2 and NOx in the road area in real time, and combine traffic flow and vehicle type data to build dynamic carbon emission models, providing a scientific basis for urban transportation carbon quota management and new energy vehicle policy formulation.

[0003] Existing devices typically consist of an extraction unit, a laser gas analysis module, and a data processing unit: the extraction unit draws road surface gas into the monitoring pipeline through a negative pressure pump, the laser module performs non-contact concentration monitoring of the flowing gas based on TDLAS (tunable diode laser absorption spectroscopy) technology, and finally outputs the carbon emission intensity through an edge computing platform.

[0004] During the operation of highway carbon emission monitoring devices, when the air extraction unit draws ambient air into the gas pipeline, it inevitably carries light suspended particles such as willow catkins into the monitoring channel. These foreign objects may accumulate and form blockages at pipe bends or on sensor surfaces. In addition, their randomly distributed particles may scatter and absorb the laser beam, causing the light intensity signal received by the optical monitoring system to be attenuated or distorted, ultimately significantly reducing the monitoring accuracy of gas component concentration. Utility Model Content

[0005] In response to the problem that lightweight suspended particles such as willow catkins can enter the monitoring channel and cause blockage, this invention proposes a highway carbon emission monitoring device to overcome the aforementioned technical problems existing in related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a highway carbon emission monitoring device, including an installation and storage component, a monitoring component is provided inside the installation and storage component, an extraction component is provided at one end of the monitoring component, a filtering component is provided at the other end of the monitoring component, and an elastic scraping component is provided at the filter end of the filtering component.

[0008] The extraction component draws external air into the monitoring component so that the monitoring component can monitor the airflow inside. The filtering component is used to filter suspended particles carried in the air, and the elastic scraping component is used to scrape off suspended particles adhering to the filtering component.

[0009] Furthermore, the installation and storage assembly includes a lower outer shell, an upper outer shell is fixedly installed on the top of the lower outer shell, a socket is fixedly connected to the bottom of the lower outer shell, and a fixing seat is fixedly installed on the bottom of the fixing seat.

[0010] Furthermore, the monitoring component includes a mounting slot, which is opened at both ends of the lower and upper outer shells. A waveform monitoring tube is movably connected inside the mounting slot. A positioning plate is fixedly connected to the outer surface of the waveform monitoring tube. The positioning plate is movably connected to the inner walls of the lower and upper outer shells. A laser sensor is provided on the outer side of the waveform monitoring tube.

[0011] Furthermore, the extraction assembly includes a vacuum pump, which is fixedly installed on the top of the upper housing. An extraction tube is fixedly installed at the extraction end of the vacuum pump, and one end of the extraction tube is fixedly installed together with the waveform monitoring tube.

[0012] Furthermore, the filtering assembly includes a filter bucket, which is fixedly connected to the waveform monitoring tube, and a filter screen is fixedly connected to the inner wall of the filter bucket.

[0013] Furthermore, the elastic scraping assembly includes a through groove, one side of which opens into the filter bucket and extends through the filter bucket. A movable frame is movably connected to the front of the filter bucket. A storage cylinder is fixedly connected to the top and bottom of the movable frame. A rotating shaft is rotatably connected inside the storage cylinder. A scraping plate is fixedly connected to the outer surface of the rotating shaft. The scraping plate is movably connected to the through groove. A torsion spring is fixedly connected between the storage cylinder and the rotating shaft.

[0014] Furthermore, a drive frame is fixedly installed on the outer side of the lower housing, and a reciprocating screw is rotatably connected inside the drive frame. The reciprocating screw is threadedly connected to the movable frame. A motor is fixedly installed on the outer side of the drive frame, and the output end of the motor is fixedly connected to the reciprocating screw. A guide frame is fixedly installed on the outer side of the upper housing, and the movable frame is movably connected to the guide frame.

[0015] This utility model has the following beneficial effects:

[0016] This invention allows external air to be drawn into the monitoring component via an extraction component. Meanwhile, a filtering component filters out light suspended particles such as willow catkins, preventing these particles from entering the monitoring component with the air. This effectively avoids blockages caused by these particles, which could prevent normal gas flow within the monitoring component. Furthermore, the laser emitted from the monitoring end of the component does not experience attenuation or distortion, ensuring the accuracy of gas concentration monitoring.

[0017] This invention uses a motor and a reciprocating screw to drive the moving frame. During this movement, the scraper plate tilts under the push of the filter bucket. After tilting at a certain angle, the scraper plate moves together with the moving frame and scrapes off the deposits on the filter screen at an angle under the elastic force of the torsion spring. The scraper plate in the tilted state can effectively suppress the re-flying of the detached suspended matter by inducing local turbulence. In addition, the scraper plate can be completely moved off the filter bucket by the moving frame, so that the scraper plate can make contact with the filter screen at an angle whether it moves forward or backward. The above settings ensure the effectiveness of cleaning foreign objects attached to the filter screen.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a highway carbon emission monitoring device, including an installation and storage component 1, a monitoring component 2 is provided inside the installation and storage component 1, an extraction component 3 is provided at one end of the monitoring component 2, a filter component 4 is provided at the other end of the monitoring component 2, and an elastic scraping component 5 is provided at the filter end of the filter component 4.

[0032] The extraction component 3 draws external air into the monitoring component 2 so that the monitoring component 2 can monitor the airflow inside it. The filter component 4 is used to filter suspended particles carried in the air, and the elastic scraping component 5 is used to scrape off suspended particles adhering to the filter component 4.

[0033] When monitoring carbon emissions on highways, the extraction component 3 draws external air into the monitoring component 2 through the filter component 4, thereby enabling the monitoring component 2 to monitor the air flowing inside. When the airflow flows into the monitoring component 2 through the filter component 4, the filter component 4 can filter light suspended particles such as willow catkins carried in the air, while the scraping end of the elastic scraping component 5 moves continuously and scrapes away and cleans the light suspended particles such as willow catkins adhering to the filter component 4.

[0034] When external air is drawn into the monitoring component 2 by the extraction component 3, the filter component 4 can filter out light suspended particles such as willow catkins carried in the air, so that these particles will not enter the monitoring component 2 with the air. This effectively avoids the phenomenon that light suspended particles such as willow catkins will block the monitoring component 2 and prevent the gas from flowing normally inside the monitoring component 2. At the same time, the laser emitted by the monitoring end of the monitoring component 2 will not be attenuated or distorted, thus ensuring the accuracy of monitoring the concentration of gas components.

[0035] In one embodiment, the installation and storage component 1 includes a lower outer shell 101, an upper outer shell 102 is fixedly installed on the top of the lower outer shell 101, a socket 103 is fixedly connected to the bottom of the lower outer shell 101, and a fixing seat 104 is fixedly installed on the bottom of the socket 103.

[0036] By fitting the socket 103 onto the bracket used for mounting cameras on the highway, and then installing the fixing seat 104 on the bottom of the socket 103 with fixing bolts, the socket 103 and the fixing seat 104 cooperate to install the lower housing 101 on the support; the upper housing 102 is connected to the lower housing 101 by fixing bolts. This arrangement makes it convenient to inspect and maintain the components installed inside the lower housing 101 and the upper housing 102.

[0037] In one embodiment, the monitoring component 2 includes a mounting groove 201, which is opened at both ends of the lower outer shell 101 and the upper outer shell 102. A waveform monitoring tube 202 is movably connected inside the mounting groove 201. A positioning plate 203 is fixedly connected to the outer surface of the waveform monitoring tube 202. The positioning plate 203 is movably connected to the inner wall of the lower outer shell 101 and the upper outer shell 102. A laser sensor 204 is provided on the outer side of the waveform monitoring tube 202.

[0038] By placing the waveform monitoring tube 202 inside the mounting slot 201 opened on the lower outer shell 101, and simultaneously making the two positioning plates 203 on the outer surface of the waveform monitoring tube 202 contact the inner wall of the lower outer shell 101, and then installing the upper outer shell 102 on top of the lower outer shell 101, the two outer shells are fixed to the waveform monitoring tube 202 through the mounting slot 201. The above arrangement makes it convenient to install the waveform monitoring tube 202. A sensor is installed on the outside of the waveform monitoring tube 202 corresponding to the laser sensor 204. When air moves inside the waveform monitoring tube 202, the laser sensor 204 emits laser light. The emitted laser light passes through the flowing air and is absorbed by the sensor. At this time, the sensor analyzes the content in the air by absorbing the laser light.

[0039] In one embodiment, the extraction component 3 includes a vacuum pump 301, which is fixedly installed on the top of the upper housing 102. An extraction tube 302 is fixedly installed at the extraction end of the vacuum pump 301, and one end of the extraction tube 302 is fixedly installed together with the waveform monitoring tube 202.

[0040] By driving the air extractor 301, the air extractor 301 draws in external air through the extraction pipe 302 and the waveform monitoring pipe 202, so that the external air can flow into the interior of the waveform monitoring pipe 202.

[0041] In one embodiment, the filter assembly 4 includes a filter bucket 401, which is fixedly connected to the waveform monitoring tube 202, and a filter screen 402 is fixedly connected to the inner wall of the filter bucket 401.

[0042] When air flows through the filter hopper 401 into the waveform monitoring tube 202, the filter screen 402 can filter out light suspended particles such as willow catkins carried in the air, thereby preventing light suspended particles such as willow catkins from flowing into the waveform monitoring tube 202 along with the air.

[0043] In one embodiment, the elastic scraping component 5 includes a through groove 501, which opens onto one side of a filter hopper 401 and extends through the filter hopper 401. A movable frame 502 is movably connected to the front of the filter hopper 401. A storage cylinder 503 is fixedly connected to both the top and bottom of the movable frame 502. A rotating shaft 504 is rotatably connected inside the storage cylinder 503. A scraping plate 505 is fixedly connected to the outer surface of the rotating shaft 504. The scraping plate 505 is movably connected to the through groove 501. A torsion spring 506 is fixedly connected between the storage cylinder 503 and the rotating shaft 504.

[0044] Lightweight suspended particles such as willow catkins filtered out will adhere to the filter screen 402 under subsequent airflow. At this point, the movable frame 502 can be moved, causing the scraper plate 505 to move via the collection cylinder 503 and the rotating shaft 504. When the scraper plate 505 comes into contact with the filter hopper 401, the movable frame 502 continues to move, causing the scraper plate 505 to pull and rotate via the rotating shaft 504 and the torsion spring 506. When the scraper plate 505 tilts to a certain angle, it can move directly into the through groove 501. At this point, the scraper plate 505 tilts under the elastic force of the torsion spring 506. The scraper 505 contacts the filter screen 402, allowing it to be tilted to scrape away light suspended particles such as willow catkins from the filter screen. Because the tilted scraper 505 obstructs the movement of the continuously flowing air behind it, the scraped-off light suspended particles are less likely to become airborne, thus ensuring the scraping effect. In the above configuration, the scraper 505 can be completely moved off the filter hopper 401 by the moving frame 502, allowing it to contact the filter screen 402 at an angle whether moving forward or backward.

[0045] In one embodiment, for the lower housing 101, a drive frame 507 is fixedly installed on the outer side of the lower housing 101, a reciprocating screw 508 is rotatably connected inside the drive frame 507, the reciprocating screw 508 is threadedly connected to the moving frame 502, a motor 509 is fixedly installed on the outer side of the drive frame 507, and the output end of the motor 509 is fixedly connected to the reciprocating screw 508. A guide frame 510 is fixedly installed on the outer side of the upper housing 102, and the moving frame 502 is movably connected to the guide frame 510.

[0046] The reciprocating screw 508 is driven by the motor 509, so that the reciprocating screw 508 drives the scraper 505 to move back and forth on the front of the filter hopper 401 via the moving frame 502. When the moving frame 502 moves, the guide frame 510 can guide the moving frame 502, so that the stability can be guaranteed when the moving frame 502 drives the scraper 505 to move.

[0047] Through the above technical solution, 1. When external air is drawn into the monitoring component 2 by the extraction component 3, the filter component 4 can filter out light suspended particles such as willow catkins carried in the air, preventing these particles from entering the monitoring component 2 with the air. This effectively avoids the phenomenon that light suspended particles such as willow catkins will block the monitoring component 2, preventing the gas from flowing normally inside the monitoring component 2. At the same time, the laser emitted from the monitoring end of the monitoring component 2 will not be attenuated or distorted, thus ensuring the accuracy of monitoring the gas component concentration; 2. The moving frame 502 is moved by the motor 509 and the reciprocating screw 508. At this time, the scraper 505 tilts under the push of the filter hopper 401. After tilting at a certain angle, the scraper 505 moves together with the moving frame 502 and scrapes off the attached material on the filter screen 402 at an angle under the elastic force of the torsion spring 506. The scraper 505 in the tilted state can effectively suppress the re-flying of the stripped suspended material by inducing local turbulence. In addition, the scraper 505 can be completely moved off the filter hopper 401 by the moving frame 502, so that the scraper 505 can tilt and contact the filter screen 402 whether it moves forward or backward. The above settings ensure the effectiveness of cleaning the foreign matter attached to the filter screen 402.
