Description

Technical Field

[0001] This invention relates to the field of carbon emission monitoring technology, specifically to a carbon emission monitoring device and method for highway engineering. Background Technology

[0002] The technical background of the carbon emission monitoring device for highway engineering lies in the fact that current carbon emission monitoring during highway construction mainly uses fixed or handheld equipment, which suffers from three major pain points: poor deployment flexibility, insufficient environmental adaptability, and interference with data accuracy. Traditional equipment is difficult to work continuously and stably in complex field environments. Its optical sensors are easily affected by temperature drift, humidity absorption, and dust blockage, leading to measurement distortion. Moreover, manual retrieval and protection are required in severe weather, which is inefficient and poses safety risks. Therefore, there is an urgent need for an integrated monitoring device that can integrate automatic deployment and retrieval, environmental parameter compensation, intelligent protection, and self-cleaning functions to achieve high-precision, unmanned, and long-term monitoring of CO2, CH4, and other gas emissions at construction sites.

[0003] Patent CN221725984U discloses a carbon sequestration monitoring device for highway engineering, including a base, a support column and a motor fixed on the base, a rotating rod fixed at the output end of the motor, a drive gear fixed at one end of the rotating rod, a driven gear meshing with the drive gear on its side, a connecting sleeve fixed on the upper surface of the driven gear, a power supply system fixed on the side of the connecting sleeve, a solar panel, a rotating plate and a monitoring machine fixed on the power supply system, a support plate rotatably connected below the rotating plate, and a monitoring head, a warning light, a display screen and adjustment buttons fixed on the monitoring machine. This patent achieves the purpose of monitoring carbon emissions from different directions by setting up a rotatable solar power supply system to drive the monitoring device to rotate simultaneously. It also allows adjustment of the orientation of the solar panel to better receive sunlight and increase conversion efficiency. However, this patent also suffers from the problem of cross-interference between sensors. Therefore, this patent proposes a carbon emission monitoring device and method for highway engineering to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a carbon emission monitoring device and monitoring method for highway engineering, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a carbon emission monitoring device for highway engineering, including a shell, a water tank fixedly connected to the rear side of the shell, and a monitoring mechanism disposed inside the shell;

[0006] The monitoring mechanism includes a monitoring end, which is slidably connected inside the outer shell. A threaded rod is rotatably connected to the bottom end of the monitoring end. A folding airbag is fixedly connected to the rear side of the monitoring end. Four exhaust channels are fixedly connected to the front side of the folding airbag. Four collection hoods are provided on both the left and right sides of the monitoring end. Multiple monitoring air slots are opened on the outer surface of each collection hood. A toothed ring is rotatably connected to the outer surface of each collection hood. A brush strip is fixedly connected to the side of the toothed ring away from the monitoring end. A toothed rack is provided in the middle of the left and right sides of the monitoring end. A lower through groove is opened on the bottom surface of the monitoring end.

[0007] A collection trough is fixedly connected to the top surface of the outer casing, a photovoltaic panel is rotatably connected to the front side of the collection trough, a storage mechanism is provided at the bottom of the water tank, and a heat dissipation mechanism is provided above the storage mechanism.

[0008] According to the above technical solution, the threaded rod is rotatably connected to the outer shell, a transverse rod is fixedly connected to the top of the inner wall of the outer shell, and the transverse rod is slidably connected to the monitoring end. The side of the folded airbag away from the monitoring end is fixedly connected to the inner wall of the outer shell. All four exhaust channels are fixedly connected to the monitoring end. A filter screen is provided on the inner wall of the monitoring air trough. The rack is fixedly connected to the inner wall of the outer shell. A square groove is opened on the bottom surface of the outer shell, and the square groove corresponds to the position of the lower through groove. Multiple drainage holes are opened on the rear side of the water trough. When the threaded rod rotates, the threaded rod pushes the monitoring end to extend outward from the inside of the outer shell, and pushes the photovoltaic panel to flip upward around the connection of the collection trough through the movement of the monitoring end from the inside of the outer shell, so that the photovoltaic panel can be laid flat to continuously provide power inside the monitoring end. At this time, the monitoring end, through the collection cover set on the side, allows the temperature sensor, humidity sensor, and gas sensor set in the collection cover to process the carbon emissions of the surrounding environment through the monitoring air trough opened in the collection cover, and transmits the measured data to the built-in analysis module of the monitoring end. The system integrates data from the analysis module. By measuring temperature changes, it reduces baseline drift that could cause errors in optical equipment such as infrared absorption methods. By measuring humidity, it avoids the absorption of specific wavelengths of infrared light by water molecules, which could affect the measurement accuracy of CO2 and CH4, thus reducing interference. In addition, by measuring data separately through collection hoods set at different locations, it avoids cross-interference caused by close proximity, which could affect the monitoring results. When the external environment is unsuitable for monitoring, such as heavy rain or strong winds, the screw rod rotates, causing the monitoring end to retract into the outer shell. At this time, the toothed ring on the outside of the collection hood gradually approaches and engages with the rack. The toothed ring engaging the rack rotates with the movement of the monitoring end. The rotating toothed ring drives the rotating cylinder to clean the dust attached to the filter screen in the monitoring air tank, preventing dust from clogging the monitoring air tank and affecting the monitoring effect. In addition, the movement of the monitoring end squeezes and folds the airbag, causing the gas inside the folded airbag to be pressurized and discharged through the exhaust channel, blowing off the dust outside the collection hood. The blown-off dust is discharged downward through the lower channel.

[0009] According to the above technical solution, the storage mechanism includes a drain baffle, which is fixedly connected to the inner wall of the collection tank. A reset base plate is slidably connected to the inner wall of the tank. A rotating shaft frame is fixedly connected to the bottom surface of the reset base plate. A rotating shaft rod is rotatably connected inside the rotating shaft frame. An upper bevel gear and a lower bevel gear are fixedly connected to the outer surfaces of the upper and lower ends of the rotating shaft rod, respectively. A vertical sliding rod is slidably connected to the bottom surface of the rotating shaft rod. A side bevel gear is meshed with the side of the lower bevel gear. A meshing block is fixedly connected to the axis of the side bevel gear. A rotating cylinder is rotatably connected to the outer side of the meshing block.

[0010] According to the above technical solution, a meshing block is provided on the side of the meshing block away from the side bevel gear, a horizontal slide rod is fixedly connected to the side of the meshing block away from the meshing block, an upper tray is fixedly connected to the bottom surface of the rotating shaft rod, and a lower tray is fixedly connected to the outer side of the bottom end of the vertical slide rod.

[0011] According to the above technical solution, the outer surface of the vertical slide rod is provided with splines, the outer surface of the horizontal slide rod is provided with splines, the rotating cylinder is fixedly connected to the outer wall of the outer shell, the end of the horizontal slide rod away from the mating block is slidably connected to the threaded rod, the threaded rod is rotatably connected to the rotating cylinder, a compression spring is provided between the upper tray and the lower tray, and the two ends of the compression spring are fixedly connected to the upper tray and the lower tray respectively. When there is light rain, rainwater falls into the collection trough and flows into the water tank through the drain baffle in the collection trough. When the rainwater accumulates to a certain amount, it will... Excess water is drained through the drain holes on the side of the water tank. During heavy rain or storms, rainwater quickly replenishes the collection tank and flows through the drainage baffle into the main tank. At this time, the drainage rate from the drain holes is lower than the rate of rainwater flowing into the tank, causing the water level to rise and increasing the pressure on the reset plate. This causes the reset plate to press against the bottom pivot bracket, which in turn applies pressure to the vertical slide rod via the pivot bracket. This compresses the spring between the upper and lower trays, and the continuously operating motor drives the vertical slide rod... When the sliding rod rotates, the vertical sliding rod transmits power to the rotating shaft rod via the outer spline. At this time, the rotating shaft bracket moves down with the rotating shaft rod, causing the upper bevel gear and the side bevel gear to approach and mesh. The upper bevel gear transmits power to the side bevel gear, causing the side bevel gear to rotate and drive the meshing block to rotate. The meshing block drives the meshing engagement block, and transmits power to the threaded rod via the horizontal sliding rod connected to the engagement block. At this time, the rotation of the threaded rod causes the monitoring end to retract into the housing. When the monitoring end is fully retracted, the monitoring end locks the threaded rod and stops rotating. At this time, the side bevel gear continues to rotate, causing the meshing block to be in an idle state. In the idle state, the meshing block will push the locking block to squeeze the elastic spring, and allow the locking block to slide through the spline on the outside of the connected horizontal slide bar and the axis of the threaded rod. After the rain stops, the water level in the water tank will decrease after being discharged through the drain hole. At this time, the gravity above the reset base plate will decrease, and the compression spring will push the upper tray, the rotating shaft and the rotating shaft frame to reset. The rotating shaft frame will move upward and drive the lower bevel gear to mesh with the side bevel gear. At this time, the side bevel gear will rotate in the opposite direction and drive the meshing block to rotate. After the meshing block and the locking block are engaged, the threaded rod will be driven to rotate through the horizontal slide bar, so that the monitoring end extends from the inside of the shell to the outside.

[0012] According to the above technical solution, the heat dissipation mechanism includes two peristaltic handles, and three peristaltic wheels are rotatably connected to the inner side of each peristaltic handle. A peristaltic tube is provided on the outer side of the peristaltic wheel. A bent tube is fixedly connected to the end of the peristaltic tube. A heat dissipation tube is fixedly connected to the end of the bent tube away from the peristaltic tube. A return pipe is fixedly connected to the end of the heat dissipation tube away from the bent tube.

[0013] According to the above technical solution, the peristaltic tube is fixedly connected to the top surface of the reset base plate, the axis of the peristaltic handle is fixedly connected to the upper bevel gear, the bending tube is located inside the folded airbag, the heat dissipation tube is located on the inner wall of the monitoring end, and the return tube extends from the inner wall of the monitoring end to the inner wall of the water tank. When the upper bevel gear rotates, it drives the coaxial peristaltic handle to rotate, which in turn drives the peristaltic wheel to rotate, causing the peristaltic wheel to squeeze the air in the peristaltic tube into the bending tube. Since the peristaltic tube is under negative pressure, it draws liquid from the water tank to balance the negative pressure. The liquid in the bending tube flows into the heat dissipation tube, which absorbs the heat generated inside the monitoring end. At the same time, the liquid flow in the heat dissipation tube carries away the heat through the return tube.

[0014] A monitoring method for a carbon emission monitoring device in highway engineering includes:

[0015] S1: When the threaded rod rotates, it pushes the monitoring end to extend outward from the inside of the shell. The movement of the monitoring end from the inside of the shell pushes the photovoltaic panel to flip upward around the connection of the collection slot, so that the photovoltaic panel can be laid flat to continuously provide power to the inside of the monitoring end. At this time, the monitoring end uses the collection cover set on the side to allow the temperature sensor, humidity sensor and gas sensor set in the collection cover to process the carbon emissions of the surrounding environment through the monitoring gas slot opened in the collection cover.

[0016] S2: The measured data is transmitted to the built-in analysis module at the monitoring end. The analysis module integrates the obtained data and reduces the baseline drift that may cause errors in optical equipment such as infrared absorption methods by measuring temperature changes. It also avoids water molecules absorbing infrared light of specific wavelengths, which could affect the measurement accuracy of CO2 and CH4, and reduces interference by measuring humidity.

[0017] S3: In addition, by measuring data separately through collection hoods set at different locations, cross-interference caused by close proximity can be avoided, which would affect the monitoring results. When the external environment is unsuitable for monitoring, such as heavy rain or strong wind, the screw rod rotates to drive the monitoring end to retract into the shell. At this time, the toothed ring on the outside of the collection hood gradually approaches and meshes with the rack. The toothed ring meshing with the rack will rotate as the monitoring end moves. The rotating toothed ring drives the rotating cylinder to clean the dust attached to the filter screen in the monitoring air tank, avoiding dust from adhering to the filter screen and causing blockage of the monitoring air tank, which would affect the monitoring effect.

[0018] S4: The movement of the monitoring end squeezes and folds the airbag, causing the gas inside the airbag to be compressed and discharged through the exhaust channel, blowing off the dust outside the collection cover. The blown-off dust is discharged downward through the lower channel. When the threaded rod rotates and pushes the monitoring end to extend, it can not only automatically lift the photovoltaic panel and lay it flat to provide continuous power, but also expose the collection cover on the side of the monitoring end to the environment.

[0019] S5: The drainage rate of the drain hole on the side of the water tank is lower than the rate of rainwater flowing into the water tank, which will increase the water level in the water tank and increase the pressure on the reset plate in the water tank. At this time, the reset plate will squeeze the bottom rotating shaft frame, and then apply pressure to the vertical slide rod through the rotating shaft frame connected to the rotating shaft rod, thereby compressing the compression spring between the upper tray and the lower tray. The continuously working motor drives the vertical slide rod to rotate. The vertical slide rod transmits power to the rotating shaft rod through the outer spline. The rotation of the threaded rod drives the monitoring end to be retracted into the housing. When the monitoring end is fully retracted, the monitoring end is stuck in the threaded rod and no longer rotates. At this time, the side bevel gear continues to rotate, which will drive the meshing block to be in an idle state. The meshing block in the idle state will push the wedge block to squeeze the elastic spring, and let the wedge block slide through the spline outside the connected horizontal slide rod and the axis of the threaded rod.

[0020] S6: When the water level in the tank is lowered after being discharged through the drain hole, the gravity above the reset base plate is reduced. The compression spring pushes the upper tray, rotating shaft rod, and rotating shaft bracket to reset. The rotating shaft bracket moves upward and drives the lower bevel gear to mesh with the side bevel gear. At this time, the side bevel gear rotates in the opposite direction and drives the meshing block to rotate. After the meshing block and the mating block are engaged, the threaded rod is driven to rotate through the horizontal slide rod, so that the monitoring end extends from the inside of the shell to the outside.

[0021] S7: When the upper bevel gear rotates, it will drive the coaxial peristaltic handle to rotate, which will drive the peristaltic wheel to rotate. This causes the peristaltic wheel to squeeze the air in the peristaltic tube into the bent tube. The peristaltic tube is under negative pressure, which will draw liquid from the water tank to balance the negative pressure. The liquid in the bent tube will flow into the heat dissipation pipe, which will absorb the heat generated inside the monitoring end. At the same time, the flow of liquid in the heat dissipation pipe will carry away the heat through the return pipe.

[0022] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0023] The carbon emission monitoring device for this highway project can automatically lift and lay out photovoltaic panels for continuous power supply. It also exposes the collection hoods on the side of the monitoring end to the environment. Utilizing multiple internal sensors (temperature, humidity, and gas), it collects environmental parameters and carbon emissions separately through a monitoring gas duct. By measuring temperature and humidity data in real time and inputting it into the built-in analysis module, it can dynamically compensate for baseline drift caused by temperature changes in optical equipment and infrared spectral interference caused by water vapor absorption. This significantly improves the accuracy and anti-interference capability of measuring gases such as CO2 and CH4. The distributed arrangement of multiple collection hoods avoids cross-interference between sensors. In severe weather, the threaded rod rotates in the reverse direction, causing the monitoring end to retract into the outer shell. At this time, the toothed ring and rack mesh and rotate, driving the rotating drum to clean the dust on the filter screen and prevent the air groove from clogging. At the same time, the retraction action squeezes and folds the air bag, forming an airflow to blow away the surface of the collection hood and discharge the dust through the lower channel, realizing the self-cleaning and dust protection of key components. The overall system has a compact structure and efficient operation. Without the need for external power, it can complete multiple functions such as monitoring unit deployment, power supply guarantee, environmental compensation, retraction protection and linkage self-cleaning with only one drive mechanism, which greatly improves the reliability, adaptability and maintenance efficiency of the monitoring system.

[0024] The carbon emission monitoring device for this highway project operates without manual intervention or additional sensor control. Through a clever mechanical structure, it utilizes the gravity of rainwater as a trigger power source. During light rain, the collection trough and water tank drain water in an orderly manner without affecting equipment operation. During heavy rain, the water level in the water tank rises, triggering a series of linked transmissions via hydraulic pressure to push the reset plate. Ultimately, the power from the motor is switched to the threaded rod through a bevel gear set and meshing block to retract the monitoring end. After retraction, an idling mechanism prevents power overload. After the rain stops, the water level in the water tank drops, a compression spring pushes the mechanism to reset, and the bevel gears switch meshing, driving the monitoring end to extend again and resume operation. This not only effectively protects the precision sensors inside the monitoring end from rainwater erosion and interference but also achieves environmental adaptive control through a purely mechanical method, improving the system's reliability, durability, and environmental adaptability.

[0025] The carbon emission monitoring device for this highway project uses a bevel gear to synchronously drive a peristaltic handle and a peristaltic wheel to squeeze a peristaltic tube. This pushes air into the bend tube to promote liquid circulation, while simultaneously using negative pressure to automatically extract rainwater from a water tank as a cooling medium. No additional water pump or electricity is required. The heat dissipation pipe directly absorbs the heat generated by the internal electronic components of the monitoring end, and the heat is carried away through the return pipe by the liquid flow, forming a continuous and effective cooling cycle. This not only solves the problem of measurement drift and shortened lifespan caused by overheating of optical and electronic components, but also makes full use of rainwater resources to achieve closed-loop utilization of energy and resources, improving the measurement accuracy and stability of the system in high-temperature environments.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 9 An embodiment of the present invention is: a carbon emission monitoring device and monitoring method for highway engineering, comprising a housing 1, a water tank 2 fixedly connected to the rear side of the housing 1, and a monitoring mechanism 5 disposed inside the housing 1;

[0038] The monitoring mechanism 5 includes a monitoring end 51, which is slidably connected inside the outer casing 1. A threaded rod 52 is rotatably connected to the bottom end of the monitoring end 51. A folding airbag 53 is fixedly connected to the rear side of the monitoring end 51. Four exhaust channels 54 are fixedly connected to the front side of the folding airbag 53. Four collection covers 55 are provided on both the left and right sides of the monitoring end 51. Multiple monitoring air grooves 57 are opened on the outer surface of each collection cover 55. A toothed ring 58 is rotatably connected to the outer surface of each collection cover 55. A brush strip 59 is fixedly connected to the side of the toothed ring 58 away from the monitoring end 51. A rack 56 is provided in the middle of the left and right sides of the monitoring end 51. A lower through groove 510 is opened on the bottom surface of the monitoring end 51.

[0039] A collection tank 3 is fixedly connected to the top surface of the outer casing 1. A photovoltaic panel 4 is rotatably connected to the front side of the collection tank 3. A storage mechanism 6 is provided at the bottom of the water tank 2. A heat dissipation mechanism 7 is provided above the storage mechanism 6.

[0040] The threaded rod 52 is rotatably connected to the outer casing 1. A transverse rod is fixedly connected to the top of the inner wall of the outer casing 1, and the transverse rod is slidably connected to the monitoring end 51. The side of the folded airbag 53 away from the monitoring end 51 is fixedly connected to the inner wall of the outer casing 1. Four exhaust channels 54 are all fixedly connected to the monitoring end 51. A filter screen is provided on the inner wall of the monitoring air tank 57. The rack 56 is fixedly connected to the inner wall of the outer casing 1. A square groove is opened on the bottom surface of the outer casing 1, and the square groove corresponds to the position of the lower through groove 510. Multiple drainage holes are opened on the rear side of the water tank 2. When the threaded rod 52 rotates, the threaded rod 52 pushes the monitoring end 51 to extend outward from the inside of the outer casing 1, and pushes the photovoltaic panel 4 to flip upward around the connection of the collection groove 3 through the movement of the monitoring end 51 from the inside of the outer casing 1, so that the photovoltaic panel 4 can be laid flat. To ensure a continuous power supply to the monitoring terminal 51, the monitoring terminal 51 uses a side-mounted collection hood 55. Temperature, humidity, and gas sensors within the collection hood 55 monitor carbon emissions from the surrounding environment via a monitoring gas trough 57. The measured data is transmitted to the built-in analysis module of the monitoring terminal 51. The analysis module synthesizes the data, reducing errors caused by baseline drift in optical devices such as infrared absorption methods by measuring temperature changes. It also measures humidity to prevent water molecules from absorbing specific wavelengths of infrared light, thus avoiding interference with CO2 and CH4 methane measurements. Furthermore, individual data measurements using collection hoods 55 at different locations prevent cross-interference caused by close proximity. The test results show that when the external environment is unsuitable for monitoring, such as heavy rain or strong winds, the screw rod 52 rotates, causing the monitoring end 51 to retract into the outer shell 1. At this time, the toothed ring 58 on the outside of the collection cover 55 gradually approaches and meshes with the rack 56. The toothed ring 58 meshing with the rack 56 rotates with the movement of the monitoring end 51. The rotating toothed ring 58 drives the rotating cylinder 69 to clean the dust attached to the filter screen in the monitoring air groove 57, preventing dust from adhering to the filter screen and causing blockage of the monitoring air groove 57, thus affecting the monitoring effect. In addition, the movement of the monitoring end 51 squeezes the folded air bag 53, causing the gas inside the folded air bag 53 to be pressurized and discharged through the exhaust channel 54, blowing off the dust outside the collection cover 55. The blown-off dust is discharged downward through the lower channel 510. When the screw rod 52 rotates... When the monitoring end 51 is extended, it not only automatically lifts and flattens the photovoltaic panel 4 for continuous power supply, but also exposes the collection cover 55 on the side of the monitoring end 51 to the environment. Using internal multi-sensor temperature, humidity, and gas data collected via the monitoring gas trough 57, environmental parameters and carbon emissions are collected separately. By measuring temperature and humidity data in real time and inputting it into the built-in analysis module, baseline drift caused by temperature changes and infrared spectral interference caused by water vapor absorption can be dynamically compensated for, significantly improving the accuracy and anti-interference capability of measuring gases such as CO2 and CH4. The distribution of multiple collection covers 55 avoids cross-interference between sensors. In severe weather, the threaded rod 52 rotates in the opposite direction, causing the monitoring end 51 to retract into the outer shell 1. At this time, the toothed ring 58 meshes with the rack 56 and rotates.The rotating drum 69 cleans the dust accumulated on the filter screen, preventing air duct blockage. Simultaneously, the retraction action compresses and folds the airbag 53, creating an airflow to blow away dust from the surface of the collection hood 55 and discharge it through the lower passage 510. This achieves self-cleaning and dust protection for key components. The overall system is compact and highly efficient. Without external power, a single drive mechanism simultaneously performs multiple functions, including monitoring unit deployment, power supply, environmental compensation, retraction protection, and linked self-cleaning, significantly improving the reliability, adaptability, and maintenance efficiency of the monitoring system.

[0041] The storage mechanism 6 includes a drain baffle 61, which is fixedly connected to the inner wall of the collection tank 3. A reset base plate 62 is slidably connected to the inner wall of the tank 2. A rotating shaft frame 63 is fixedly connected to the bottom surface of the reset base plate 62. A rotating shaft rod 67 is rotatably connected inside the rotating shaft frame 63. An upper bevel gear 64 and a lower bevel gear 65 are fixedly connected to the outer surfaces of the upper and lower ends of the rotating shaft rod 67, respectively. A vertical sliding rod 66 is slidably connected to the bottom surface of the rotating shaft rod 67. A side bevel gear 68 is meshed with the side of the lower bevel gear 65. A meshing block 610 is fixedly connected to the axis of the side bevel gear 68. A rotating cylinder 69 is rotatably connected to the outer side of the meshing block 610. A locking block 611 is provided on the side of the meshing block 610 away from the side bevel gear 68. A horizontal slide rod 612 is fixedly connected to the side, an upper tray 613 is fixedly connected to the bottom surface of the rotating shaft rod 67, and a lower tray 614 is fixedly connected to the outer side of the bottom end of the vertical slide rod 66. The outer surface of the vertical slide rod 66 and the outer surface of the horizontal slide rod 612 are both provided with splines. The rotating cylinder 69 is fixedly connected to the outer wall of the outer casing 1. The end of the horizontal slide rod 612 away from the engaging block 611 is slidably connected to the threaded rod 52. The threaded rod 52 is rotatably connected to the rotating cylinder 69. A compression spring is provided between the upper tray 613 and the lower tray 614, and both ends of the compression spring are fixedly connected to the upper tray 613 and the lower tray 614 respectively. During light rain, rainwater falls into the collection tank 3 and flows into the water tank 2 through the leaking baffle 61 inside the collection tank 3. When a certain amount of rainwater accumulates, it will flow through the water tank... The drainage holes on the sides drain excess water. In heavy rain or storms, rainwater quickly replenishes the collection tank 3 and flows through the drainage baffle 61 into the water tank 2. At this time, the drainage rate of the drainage holes on the side of the water tank 2 is lower than the rate of rainwater flowing into the water tank 2, which increases the water level in the water tank 2 and increases the pressure on the reset bottom plate 62 inside the water tank 2. At this time, the reset bottom plate 62 will squeeze the bottom rotating shaft frame 63, and then apply pressure to the vertical slide rod 66 through the rotating shaft rod 67 connected to the rotating shaft frame 63, thereby compressing the compression spring between the upper tray 613 and the lower tray 614. The continuously working motor 8 drives the vertical slide rod 66 to rotate. The vertical slide rod 66 transmits power to the rotating shaft rod 67 through the outer spline. At this time, the rotating shaft frame 63 moves down with the rotating shaft rod 67 and... The upper bevel gear 64 and the side bevel gear 68 are brought close together for meshing. The upper bevel gear 64 drives the side bevel gear 68, causing the side bevel gear 68 to rotate and drive the meshing block 610 to rotate. The meshing block 610 drives the meshing engagement block 611, and through the transverse slide bar 612 connected to the engagement block 611, it drives the threaded rod 52. At this time, the rotation of the threaded rod 52 causes the monitoring end 51 to retract into the housing 1. When the monitoring end 51 is fully retracted, the monitoring end 51 locks the threaded rod 52 and stops rotating. At this time, the side bevel gear 68 continues to rotate, causing the meshing block 610 to be in an idle state. The idle meshing block 610 pushes the engagement block 611 to compress the elastic spring, and allows the engagement block 611 to slide with the axis of the threaded rod 52 through the spline outside the connected transverse slide bar 612. After the rain stops...After the water level in the water tank 2 is discharged through the drain hole, the gravity above the reset base plate 62 decreases. The compression spring pushes the upper tray 613, the rotating shaft rod 67, and the rotating shaft bracket 63 to reset. The rotating shaft bracket 63 moves upward, causing the lower bevel gear 65 to mesh with the side bevel gear 68. At this time, the side bevel gear 68 rotates in the opposite direction, causing the meshing block 610 to rotate. After the meshing block 610 and the engaging block 611 engage, the threaded rod 52 rotates through the horizontal slide rod 612, causing the monitoring end 51 to extend from the inside of the outer shell 1 to the outside. The whole process does not require manual intervention or additional sensor control. Through a clever mechanical structure, the gravity of the rainwater is used as the trigger power source. When it rains lightly, the collection tank 3 and the water tank 2 can drain water in an orderly manner. Without affecting equipment operation, during heavy rain, the water level in the tank 2 rises, triggering a series of linked transmissions by hydraulically pushing the reset base plate 62. Ultimately, through the bevel gear set and meshing block 610, the power of the motor 8 is switched to the threaded rod 52 to retract the monitoring end 51. After retraction, an idling mechanism prevents power overload. After the rain stops, the water level in the tank 2 drops, the compression spring pushes the mechanism to reset, and the bevel gears switch meshing, driving the monitoring end 51 to extend again and resume operation. This not only effectively protects the precision sensors inside the monitoring end 51 from rainwater erosion and interference, but also achieves environmental adaptive control through a purely mechanical means, improving the system's reliability, durability, and environmental adaptability.

[0042] The heat dissipation mechanism 7 includes two peristaltic handles 71. Three peristaltic wheels 72 are rotatably connected to the inner side of each peristaltic handle 71. A peristaltic tube 73 is provided on the outer side of each peristaltic wheel 72. A bent tube 74 is fixedly connected to the end of the peristaltic tube 73. A heat dissipation tube 75 is fixedly connected to the end of the bent tube 74 away from the peristaltic tube 73. A return tube 76 is fixedly connected to the end of the heat dissipation tube 75 away from the bent tube 74. The peristaltic tube 73 is fixedly connected to the top surface of the reset base plate 62. The peristaltic handles 71... The upper bevel gear 64 is fixedly connected to the axis of the device. The bent tube 74 is located inside the folded airbag 53. The heat dissipation tube 75 is located on the inner wall of the monitoring end 51. The return tube 76 passes through the inner wall of the monitoring end 51 to the inner wall of the water tank 2. When the upper bevel gear 64 rotates, it will drive the coaxial peristaltic handle 71 to rotate, which will drive the peristaltic wheel 72 to rotate. This causes the peristaltic wheel 72 to squeeze the air in the peristaltic tube 73 into the bent tube 74, while the peristaltic tube 73 is under negative pressure. The system draws liquid from the water tank 2 to balance the negative pressure. The liquid in the bent tube 74 flows into the heat dissipation tube 75, which absorbs the heat generated inside the monitoring end 51. At the same time, the liquid flow in the heat dissipation tube 75 carries away the heat through the return tube 76. The rotation of the upper bevel gear 64 synchronously drives the peristaltic handle 71 and the peristaltic wheel 72 to squeeze the peristaltic tube 73. On the one hand, air is pushed into the bent tube 74 to promote liquid circulation. On the other hand, rainwater in the water tank 2 is automatically drawn out by the negative pressure as a cooling medium. No additional water pump or electricity is required. The heat dissipation tube 75 directly absorbs the heat generated by the electronic components inside the monitoring end 51 and carries away the heat through the return tube 76 by the liquid flow, forming a continuous and effective cooling cycle. This not only solves the problem of measurement drift and shortened lifespan caused by overheating of optical and electronic components, but also makes full use of rainwater resources to achieve closed-loop utilization of energy and resources, and improves the measurement accuracy and stability of the system in high-temperature environments.

[0043] Working principle: When the threaded rod 52 rotates, it pushes the monitoring end 51 to extend outward from inside the outer casing 1. This movement of the monitoring end 51 from inside the outer casing 1 pushes the photovoltaic panel 4 to rotate upward around the connection point of the collection groove 3, allowing the photovoltaic panel 4 to be laid flat inside the monitoring end 51 to continuously provide power. At this time, the monitoring end 51, through the collection cover 55 set on the side, allows the temperature sensor, humidity sensor, and gas sensor installed inside the collection cover 55 to process the carbon emissions of the surrounding environment through the monitoring gas groove 57 opened in the collection cover 55. The measured data is transmitted to the built-in analysis module of the monitoring end 51. The analysis module synthesizes the obtained data and, by measuring temperature changes, reduces the baseline drift that may cause optical equipment such as infrared absorption methods. To reduce errors, humidity is measured to avoid water molecules absorbing specific wavelengths of infrared light, which could affect the measurement accuracy of CO2 and CH4 methane, thus reducing interference. Furthermore, separate measurements using collection hoods 55 at different locations prevent cross-interference caused by close proximity, thus avoiding impact on monitoring results. When the external environment is unsuitable for monitoring, such as heavy rain or strong winds, the screw rod 52 rotates, causing the monitoring end 51 to retract into the outer shell 1. At this time, the toothed ring 58 on the outside of the collection hood 55 gradually approaches and engages with the rack 56. The toothed ring 58 engaging the rack 56 rotates with the movement of the monitoring end 51. The rotating toothed ring 58 drives the rotating drum 69 to clean the dust adhering to the filter screen inside the monitoring gas tank 57, preventing dust from adhering to the filter screen and causing problems in the monitoring gas tank 57. Blockage can affect monitoring performance. Furthermore, the movement of the monitoring end 51 compresses and folds the airbag 53, causing the gas inside to be expelled through the exhaust channel 54, blowing away dust outside the collection cover 55. The blown-off dust is then discharged downwards through the lower channel 510. When the threaded rod 52 rotates and pushes the monitoring end 51 out, it not only automatically lifts and flattens the photovoltaic panel 4 for continuous power supply, but also exposes the collection cover 55 on the side of the monitoring end 51 to the environment. Internal multi-sensor temperature, humidity, and gas data are collected separately for environmental parameters and carbon emissions through the monitoring air trough 57. By measuring temperature and humidity data in real time and inputting it into the built-in analysis module, baseline drift caused by temperature changes and infrared spectral interference caused by water vapor absorption can be dynamically compensated for. This significantly improves the accuracy and anti-interference capability of measuring gases such as CO2 and CH4. The distribution of multiple collection hoods 55 avoids cross-interference between sensors. In severe weather, the threaded rod 52 rotates in the reverse direction, causing the monitoring end 51 to retract into the outer shell 1. At this time, the toothed ring 58 meshes with the rack 56 and rotates, driving the rotating drum 69 to clean the dust accumulated on the filter screen and prevent the air groove from clogging. At the same time, the contraction action squeezes and folds the air bag 53, forming an airflow to blow away the surface of the collection hood 55 and discharge the dust through the lower passage 510, realizing the self-cleaning and dust protection of key components. The overall system has a compact structure and efficient operation. Without the need for external power, it can complete multiple functions such as monitoring unit deployment, power supply guarantee, environmental compensation, contraction protection and linkage self-cleaning with only one drive mechanism.This significantly improves the reliability, adaptability, and maintenance efficiency of the monitoring system;

[0044] During light rain, rainwater falls into the collection trough 3 and flows into the water tank 2 through the drain baffle 61 inside the collection trough 3. When the rainwater accumulates to a certain amount, the excess water is discharged through the drain holes on the side of the water tank 2. During heavy rain or storms, rainwater quickly replenishes the collection trough 3 and flows into the water tank 2 through the drain baffle 61. At this time, the discharge rate of the drain holes on the side of the water tank 2 is lower than the rate of rainwater flowing into the water tank 2, which increases the water level in the water tank 2 and increases the pressure on the reset bottom plate 62 inside the water tank 2. At this time, the reset bottom plate 62 will squeeze the bottom pivot bracket 63, and then apply pressure to the vertical slide rod 66 through the pivot rod 67 connected to the pivot bracket 63, thereby compressing the compression spring between the upper tray 613 and the lower tray 614, and continuing operation. The motor 8 drives the vertical slide rod 66 to rotate. The vertical slide rod 66 transmits power to the rotating shaft rod 67 through the outer spline. At this time, the rotating shaft bracket 63 moves down with the rotating shaft rod 67 and drives the upper bevel gear 64 to mesh with the side bevel gear 68. The upper bevel gear 64 transmits power to the side bevel gear 68, causing the side bevel gear 68 to rotate and drive the meshing block 610 to rotate. The meshing block 610 drives the meshing engagement block 611, and transmits power to the threaded rod 52 through the horizontal slide rod 612 connected to the engagement block 611. At this time, the rotation of the threaded rod 52 drives the monitoring end 51 to retract into the housing 1. When the monitoring end 51 is fully retracted, the monitoring end 51 locks the threaded rod 52 and stops rotating. At this time, the side bevel gear 68 continues to rotate, which will cause the meshing block 610 to be in an idle state. The meshing block 610 in the idle state The mechanism pushes the engaging block 611 to compress the elastic spring, allowing the engaging block 611 to slide along the spline on the connected horizontal slide bar 612 and the axis of the threaded rod 52. After the rain stops, the water level in the water tank 2 decreases after being drained through the drain hole. At this time, the weight above the reset base plate 62 decreases, and the compressed spring pushes the upper tray 613, the rotating shaft rod 67, and the rotating shaft bracket 63 to reset. The rotating shaft bracket 63 moves upward, causing the lower bevel gear 65 to mesh with the side bevel gear 68. At this time, the side bevel gear 68 rotates in the opposite direction, causing the engaging block 610 to rotate. After the engaging block 610 and the engaging block 611 mesh, the threaded rod 52 rotates through the horizontal slide bar 612, causing the monitoring end 51 to extend from inside the outer casing 1 outward. The entire process requires no manual intervention or additional sensor control, utilizing the weight of the rainwater itself through a clever mechanical structure. Using force as the triggering power source, during light rain, the collection tank 3 and water tank 2 can drain water in an orderly manner without affecting the operation of the equipment. During heavy rain, the water level in water tank 2 rises, which triggers a series of linkage transmissions by hydraulically pushing the reset base plate 62. Finally, the power of the motor 8 is switched to the threaded rod 52 through the bevel gear set and meshing block 610 to realize the recovery of the monitoring end 51. After the recovery is completed, the idling mechanism avoids power overload. After the rain stops, the water level in water tank 2 drops, the compression spring pushes the mechanism to reset and the bevel gear switches the meshing relationship, driving the monitoring end 51 to extend again and resume operation. This not only effectively protects the precision sensor inside the monitoring end 51 from rainwater erosion and interference, but also realizes environmental adaptive control through a purely mechanical means, improving the reliability, durability and environmental adaptability of the system.

[0045] When the upper bevel gear 64 rotates, it drives the coaxial peristaltic handle 71 to rotate, which in turn drives the peristaltic wheel 72 to rotate. This causes the peristaltic wheel 72 to squeeze the air in the peristaltic tube 73 into the bent tube 74. The peristaltic tube 73 is under negative pressure, which draws liquid from the water tank 2 to balance the negative pressure. The liquid in the bent tube 74 flows into the heat dissipation pipe 75, which absorbs the heat generated inside the monitoring end 51. At the same time, the liquid flow in the heat dissipation pipe 75 carries away the heat through the return pipe 76. The rotation of the upper bevel gear 64 synchronously drives the peristaltic handle 71 and the peristaltic wheel 72 to squeeze the peristaltic tube 73. 3. On the one hand, air is pushed into the bend pipe 74 to promote liquid circulation. On the other hand, rainwater in the water tank 2 is automatically extracted by negative pressure as a cooling medium. No additional water pump or electricity is required. The heat dissipation pipe 75 directly absorbs the heat generated by the electronic components inside the monitoring end 51 and carries the heat away through the return pipe 76 by the liquid flow, forming a continuous and effective cooling cycle. This not only solves the problem of measurement drift and shortened lifespan caused by overheating of optical and electronic components, but also makes full use of rainwater resources to achieve closed-loop utilization of energy and resources, and improves the measurement accuracy and stability of the system in high-temperature environments.

[0046] A monitoring method for a carbon emission monitoring device in highway engineering includes:

[0047] S1: When the threaded rod 52 rotates, the threaded rod 52 pushes the monitoring end 51 to extend outward from the inside of the outer shell 1, and pushes the photovoltaic panel 4 to flip upward around the connection of the collection groove 3 through the movement of the monitoring end 51 from the inside of the outer shell 1, so that the photovoltaic panel 4 can be laid flat inside the monitoring end 51 to continuously provide power. At this time, the monitoring end 51, through the collection cover 55 set on the side, allows the temperature sensor, humidity sensor and gas sensor set in the collection cover 55 to process the carbon emissions of the surrounding environment through the monitoring gas groove 57 opened in the collection cover 55.

[0048] S2: The measured data is transmitted to the built-in analysis module of the monitoring terminal 51. The analysis module integrates the obtained data and reduces the baseline drift that may be caused by the infrared absorption method and other optical equipment by measuring temperature changes. It also avoids water molecules absorbing infrared light of specific wavelengths, which may affect the measurement accuracy of CO2 and CH4 methane, and reduces interference by measuring humidity.

[0049] S3: In addition, by measuring data separately through collection covers 55 set at different positions, cross-interference caused by close proximity can be avoided, which would affect the monitoring results. When the external environment is unsuitable for monitoring, such as heavy rain or strong wind, the screw rod 52 rotates to drive the monitoring end 51 to retract into the outer shell 1. At this time, the toothed ring 58 on the outside of the collection cover 55 gradually approaches and meshes with the rack 56. The toothed ring 58 meshing with the rack 56 will rotate as the monitoring end 51 moves. The rotating toothed ring 58 drives the rotating drum 69 to clean the dust attached to the filter screen in the monitoring air tank 57, so as to avoid dust adhering to the filter screen and causing the monitoring air tank 57 to be blocked, thus affecting the monitoring effect.

[0050] S4: The movement of the monitoring end 51 squeezes and folds the airbag 53, causing the gas inside the airbag 53 to be compressed and discharged through the exhaust channel 54, blowing off the dust outside the collection cover 55. The blown-off dust is discharged downward through the lower channel 510. When the threaded rod 52 rotates and pushes the monitoring end 51 to extend, it can not only automatically lift the photovoltaic panel 4 and lay it flat to continuously supply power, but also expose the collection cover 55 on the side of the monitoring end 51 to the environment.

[0051] S5: The drainage rate of the drain hole on the side of the water tank 2 is lower than the rate of rainwater flowing into the water tank 2, which will increase the water level in the water tank 2 and increase the pressure on the reset bottom plate 62 in the water tank 2. At this time, the reset bottom plate 62 will squeeze the bottom rotating shaft frame 63, and then apply pressure to the vertical slide rod 66 through the rotating shaft rod 67 connected to the rotating shaft frame 63, thereby compressing the compression spring between the upper tray 613 and the lower tray 614. The continuously working motor 8 drives the vertical slide rod 66 to rotate. The vertical slide rod 66 transmits to the rotating shaft rod 67 through the outer spline. The rotation of the threaded rod 52 drives the monitoring end 51 to be retracted into the housing 1. When the monitoring end 51 is fully retracted, the monitoring end 51 jams the threaded rod 52 and no longer rotates. At this time, the side bevel gear 68 continues to rotate, which will drive the meshing block 610 to be in an idle state. The meshing block 610 in the idle state will push the wedge block 611 to squeeze the elastic spring, and let the wedge block 611 slide with the axis of the threaded rod 52 through the spline outside the connected horizontal slide rod 612.

[0052] S6: When the water level in the water tank 2 is discharged through the drain hole, the gravity above the reset base plate 62 is reduced. The compression spring pushes the upper tray 613, the rotating shaft rod 67 and the rotating shaft frame 63 to reset. The rotating shaft frame 63 moves up and drives the lower bevel gear 65 to mesh with the side bevel gear 68. At this time, the side bevel gear 68 rotates in the opposite direction and drives the meshing block 610 to rotate. After the meshing block 610 and the mating block 611 are engaged, the threaded rod 52 is driven to rotate through the horizontal slide rod 612, so that the monitoring end 51 extends from the inside of the outer shell 1 to the outside.

[0053] S7: When the upper bevel gear 64 rotates, the upper bevel gear 64 will drive the coaxial peristaltic handle 71 to rotate, which will drive the peristaltic wheel 72 to rotate, so that the peristaltic wheel 72 squeezes the air in the peristaltic tube 73 into the bent tube 74. The peristaltic tube 73 is in a negative pressure state, which will draw liquid from the water tank 2 to balance the negative pressure. The liquid in the bent tube 74 will flow into the heat dissipation pipe 75, which will absorb the heat generated inside the monitoring end 51. At the same time, the liquid flow in the heat dissipation pipe 75 will carry away the heat through the return pipe 76.
