Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission monitoring, and in particular to a carbon emission monitoring device and a monitoring method for a highway project. Background Art

[0002] The technical background of the carbon emission monitoring device for highway projects is that carbon emission monitoring during the current highway construction phase mostly uses fixed or handheld equipment, which has 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 outdoor environments. Its optical sensors are easily affected by temperature drift, humidity absorption, and dust blockage, resulting in measurement distortion. In addition, manual recovery 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 retraction, 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 publication number CN221725984U discloses a carbon sink monitoring device for highway engineering projects, comprising a base, a support column and a motor fixed to the base, a rotating rod fixed to the output end of the motor, a driving gear fixed to one end of the rotating rod, a driven gear meshing with the side of the driving gear, a connecting sleeve fixed to the upper surface of the driven gear, a power supply system fixed to the side of the connecting sleeve, a solar panel, a rotating plate and a monitoring machine fixed to the power supply system, a support plate rotatably connected to the bottom of the rotating plate, and a monitoring head, a warning light, a display screen and an adjustment button fixed to the monitoring machine. This patent achieves the purpose of monitoring carbon emissions in different directions by providing a rotatable solar power supply system to drive the monitoring device to rotate simultaneously, and can adjust the orientation of the solar panel so that it can be better exposed to the sun, thereby increasing the conversion efficiency. However, this patent still has the problem of cross-interference between sensors. Therefore, a carbon emission monitoring device for highway engineering projects and a monitoring method thereof are proposed to solve the above-mentioned 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 a monitoring method for highway engineering in view of the above-mentioned deficiencies in the prior art.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a carbon emission monitoring device for highway engineering, comprising a housing, a water tank fixedly connected to the rear side of the housing, and a monitoring mechanism disposed inside the housing; The monitoring mechanism includes a monitoring end, which is slidably connected to the inside of the shell, and the bottom end of the monitoring end is rotatably connected to a threaded rod, the rear side of the monitoring end is fixedly connected to a folding airbag, and the front side of the folding airbag is fixedly connected to four exhaust channels, and four collecting covers are provided on the left and right sides of the monitoring end, and the outer surface of each collecting cover is provided with a plurality of monitoring air grooves, and the outer surface of each collecting cover is rotatably connected to a gear ring, and the side of the gear ring away from the monitoring end is fixedly connected to a brush strip, and a rack is provided in the middle of the left and right sides of the monitoring end, and the bottom surface of the monitoring end is provided with a lower through groove.

[0006] The top surface of the shell is fixedly connected with a collecting tank, the front side of the collecting tank is rotatably connected with a photovoltaic panel, the bottom of the tank is provided with a storage mechanism, and the top of the storage mechanism is provided with a heat dissipation mechanism.

[0007] According to the above technical solution, the threaded rod is rotatably connected to the shell, and the top of the inner wall of the shell is fixedly connected to a transverse rod, and the transverse rod is slidably connected to the monitoring end, and the side of the folded airbag away from the monitoring end is fixedly connected to the inner wall of the shell, and the exhaust channels are fixedly connected to the monitoring end at all four sides, and the inner wall of the monitoring gas groove is provided with a filter, and the rack is fixedly connected to the inner wall of the shell, and the bottom surface of the shell is provided with a square groove, and the square groove corresponds to the position of the lower through groove, and the rear side of the water groove is provided with multiple drainage holes. When the threaded rod rotates, the threaded rod pushes the monitoring end to extend outward from the inside of the shell, and the photovoltaic panel is pushed upward around the collection groove connection through the movement of the monitoring end from the inside of the shell, so that the photovoltaic panel can be laid flat to continuously provide electrical energy to the inside of the monitoring end. At this time, the monitoring end uses the collection cover set on the side to make the temperature sensor, humidity sensor, and gas sensor set in the collection cover perform item-by-item processing on the carbon emissions of the surrounding environment through the monitoring gas groove opened in the collection cover, and the measured data is transmitted to the built-in analysis module of the monitoring end. The analysis module integrates the data obtained by the analysis module and measures temperature changes to reduce the baseline drift and errors that may occur in optical equipment such as infrared absorption methods. By measuring humidity, water molecules are prevented from absorbing infrared light of specific wavelengths, which affects the measurement accuracy of CO2 and CH4, and reduces interference. In addition, by measuring data separately through collection covers set at different positions, cross-interference caused by close distances can be avoided, which affects the monitoring results. When the external environment is in an environment unsuitable for monitoring, such as heavy rain or strong winds, the monitoring end is retracted into the shell by rotating the threaded rod. At this time, the gear ring on the outside of the collection cover gradually approaches and engages with the rack. The gear ring engaged with the rack rotates with the movement of the monitoring end. The rotating gear ring drives the rotating drum to clean dust attached to the filter in the monitoring gas tank, preventing dust from clogging the filter and affecting the monitoring effect. In addition, the movement of the monitoring end squeezes the folded airbag, causing the gas inside the folded airbag to be pressurized and discharged through the exhaust channel, blowing off the dust outside the collection cover. The blown dust is then discharged downward through the lower through-channel.

[0008] According to the above technical solution, the storage mechanism includes a water leakage baffle, which is fixedly connected to the inner wall of the collecting trough, and the inner wall of the water trough is slidably connected to a reset base plate, and the bottom surface of the reset base plate is fixedly connected to a rotating shaft frame, and the internal rotation of the rotating shaft frame is connected to a rotating shaft rod, and the upper and lower end outer surfaces of the rotating shaft rod are respectively fixedly connected to an upper bevel gear and a lower bevel gear, and the bottom surface of the rotating shaft rod is slidably connected to a vertical sliding rod, and the side surface of the lower bevel gear is meshedly connected to a side bevel gear, and an engaging block is fixedly connected to the axis of the side bevel gear, and the outer side of the engaging block is rotatably connected to a rotating drum.

[0009] According to the above technical solution, an engaging block is provided on the side of the engaging block away from the side bevel gear, and a horizontal sliding rod is fixedly connected to the side of the engaging block away from the engaging block. The bottom surface of the rotating shaft rod is fixedly connected to the upper tray, and the outer side of the bottom end of the vertical sliding rod is fixedly connected to the lower tray.

[0010] According to the above technical solution, the outer surface of the vertical sliding rod is provided with a spline, the outer surface of the horizontal sliding rod is provided with a spline, the rotating drum is fixedly connected to the outer wall of the shell, the end of the horizontal sliding rod away from the fitting block is slidably connected to the threaded rod, the threaded rod is rotatably connected to the rotating drum, a compression spring is provided between the upper tray and the lower tray, and the two ends of the compression spring are respectively fixedly connected to the upper tray and the lower tray. When it rains lightly, rainwater falls into the collection trough and flows into the water tank through the leaking partition in the collection trough. When a certain amount of rainwater accumulates, it will pass through The drainage holes on the side of the sink drain excess water. When it rains heavily or rainstorms, rainwater will quickly replenish the collection tank and flow from the collection tank through the leaking baffle into the sink. At this time, the drainage rate of the drainage holes on the side of the sink is lower than the rate of rainwater flowing into the sink, which will increase the water level in the sink and increase the pressure on the reset bottom plate in the sink. At this time, the reset bottom plate will squeeze the bottom shaft frame, and then press the vertical slide bar through the shaft rod connected to the shaft frame, so that the compression spring between the upper tray and the lower tray is compressed, and the continuously working motor drives the vertical slide bar to move forward. The sliding rod rotates, and the vertical sliding rod transmits the rotation shaft rod through the outer spline. At this time, the rotating shaft frame moves down together with the rotating shaft rod and drives the upper bevel gear and the side bevel gear to engage with each other. The upper bevel gear transmits the side bevel gear, so that the rotation of the side bevel gear drives the meshing block to rotate, and the meshing block drives the meshing fitting block and transmits the threaded rod through the horizontal sliding rod connected to the fitting block. At this time, the rotation of the threaded rod drives the monitoring end to be retracted into the shell. When the monitoring end is fully retracted, the monitoring end is stuck in the threaded rod and no longer rotates. At this time, the continuous rotation of the side bevel gear will drive the meshing block to be in an idling state. The meshing block in the idling state will push the fitting block to squeeze the elastic spring, and allow the fitting block to slide through the spline outside the connected horizontal sliding rod and the axis of the threaded rod. After the rain stops, the water level in the sink is discharged through the drain hole and then drops. At this time, the gravity above the reset bottom plate is reduced, and the compression spring pushes the upper tray, the rotating shaft rod and the rotating shaft frame to reset. The rotating shaft frame moves up and drives the lower bevel gear to engage with the side bevel gear. At this time, the side bevel gear rotates in the opposite direction to drive the meshing block to rotate. After the meshing block and the fitting block are engaged, the horizontal sliding rod drives the threaded rod to rotate, so that the monitoring end extends outward from the inside of the shell.

[0011] According to the above technical solution, the heat dissipation mechanism includes two peristaltic handles, and the inner side of each peristaltic handle is rotatably connected to three peristaltic wheels. A peristaltic tube is provided on the outer side of the peristaltic wheel, and the end of the peristaltic tube is fixedly connected to a bending tube. The end of the bending tube away from the peristaltic tube is fixedly connected to a heat dissipation tube, and the end of the heat dissipation tube away from the bending tube is fixedly connected to a return pipe.

[0012] 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 bent 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 passes through the inner wall of the monitoring end to the inner wall of the water tank. When the upper bevel gear rotates, the upper bevel gear will drive the coaxial peristaltic handle to rotate and drive the peristaltic wheel to rotate, so that the peristaltic wheel squeezes the air in the peristaltic tube into the bent tube, and the peristaltic tube is in a negative pressure state, which will draw liquid from the water tank to balance the negative pressure. The liquid in the bent tube will pass into the heat dissipation tube, and the heat generated inside the monitoring end will be absorbed by the heat dissipation tube, and the heat will be taken away through the return tube by the flow of liquid in the heat dissipation tube.

[0013] A monitoring method for a carbon emission monitoring device of a highway project, comprising: S1: When the threaded rod rotates, the threaded rod pushes the monitoring end to extend outward from the inside of the housing, and the monitoring end moves outward from the inside of the housing to push the photovoltaic panel to flip upward around the connection of the collection tank, 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 enable the temperature sensor, humidity sensor, and gas sensor set in the collection cover to perform itemized processing of carbon emissions in the surrounding environment through the monitoring gas slot opened in the collection cover; S2: The measured data is transmitted to the built-in analysis module of the monitoring terminal. The analysis module integrates the obtained data and reduces the baseline drift of optical equipment such as infrared absorption method by measuring temperature changes, which may cause errors. By measuring humidity, it prevents water molecules from absorbing infrared light of specific wavelengths, which affects the measurement accuracy of CO2 and CH4, and reduces interference. S3: In addition, by measuring data separately through collection covers set at different positions, cross interference caused by close distances can be avoided, which affects the monitoring results. When the external environment is in an environment not suitable for monitoring, such as heavy rain or strong winds, the monitoring end is retracted into the shell by rotating the threaded rod. At this time, the toothed ring on the outside of the collection cover gradually approaches and engages with the rack. The toothed ring engaged with the rack will rotate as the monitoring end moves. The rotating toothed ring drives the rotating drum to clean the dust attached to the filter in the monitoring gas tank, avoiding dust adhesion to the filter and clogging the monitoring gas tank, which affects the monitoring effect. S4: The monitoring end moves to squeeze the folded airbag, causing the gas inside the folded airbag to be discharged through the exhaust channel under pressure, blowing off the dust outside the collection cover. The blown dust is then discharged downward through the lower through-groove. When the threaded rod rotates and pushes the monitoring end out, it not only automatically lifts up the photovoltaic panel and lays it flat to provide continuous power supply, but also exposes the collection cover on the side of the monitoring end to the environment. S5: The drainage rate of the drainage hole on the side of the sink is lower than the rate of rainwater flowing into the sink, which will increase the water level in the sink and increase the pressure on the reset base plate in the sink. At this time, the reset base plate will squeeze the bottom shaft frame, and then apply pressure to the vertical slide bar through the shaft rod connected to the shaft frame, so that the compression spring between the upper tray and the lower tray is compressed. The continuously working motor drives the vertical slide bar to rotate. The vertical slide bar transmits the rotation shaft rod through the outer spline. The rotation of the threaded rod drives the monitoring end to be stored back into the shell. When the monitoring end is fully stored, the monitoring end is stuck in the threaded rod and no longer rotates. At this time, the continuous rotation of the side bevel gear will drive the meshing block to an idling state. The idling meshing block will push the fitting block to squeeze the elastic spring and allow the fitting block to slide with the axis of the threaded rod through the spline outside the connected horizontal slide bar; S6: When the water level in the tank is discharged through the drain hole and then drops, the gravity above the reset bottom plate decreases, and the compression spring pushes the upper tray, the rotating shaft rod, and the rotating shaft frame to reset. The rotating shaft frame moves upward, driving the lower bevel gear to engage with the side bevel gear. At this time, the side bevel gear rotates in the opposite direction, driving the meshing block to rotate. After the meshing block and the fitting block are fitted, the horizontal sliding rod drives the threaded rod to rotate, causing the monitoring end to extend outward from the inside of the housing; S7: When the upper bevel gear rotates, the upper bevel gear will drive the coaxial peristaltic handle to rotate and drive the peristaltic wheel to rotate, so that the peristaltic wheel squeezes the air in the peristaltic tube into the bending tube. The peristaltic tube is in a negative pressure state and will draw liquid from the water tank to balance the negative pressure. The liquid in the bending tube will flow into the heat dissipation pipe, and the heat generated inside the monitoring end will be absorbed by the heat dissipation pipe. At the same time, the heat will be taken away through the reflux pipe by the flow of liquid in the heat dissipation pipe.

[0014] The present invention adopts the above technical solution, which can bring the following beneficial effects: The carbon emission monitoring device of this highway project can automatically lift and lay the photovoltaic panels flat to provide continuous power supply. It can also expose the collection cover on the side of the monitoring end to the environment, and use internal multiple sensors (temperature, humidity, gas) to collect environmental parameters and carbon emissions through the monitoring gas tank. By measuring temperature and humidity data in real time and inputting them into the built-in analysis module, it can dynamically compensate for the baseline drift of optical equipment caused by temperature changes and infrared spectrum interference caused by water vapor absorption, significantly improving the accuracy and anti-interference ability of measuring gases such as CO2 and CH4. The distributed setting of multiple collection covers avoids cross interference between sensors. In bad weather, the threaded rod rotates in the opposite direction to drive the monitoring end to retract into the shell. At this time, the gear ring engages and rotates with the rack, driving the drum to clean the dust on the filter screen to prevent the air groove from being blocked. At the same time, the contraction action squeezes the folded airbag, forming an airflow to blow the surface of the collection cover and discharge the dust through the lower groove, realizing self-cleaning and dust-proof protection of key components. The overall system has a compact structure and efficient operation. Without the need for external power, it only relies on one set of drive mechanism to simultaneously complete the deployment of the monitoring unit, power supply guarantee, environmental compensation, contraction protection and linkage self-cleaning functions, which greatly improves the reliability, adaptability and maintenance efficiency of the monitoring system.

[0015] The carbon emission monitoring device of this highway project does not require human intervention or additional sensor control throughout the entire process. Through a clever mechanical structure, it uses the gravity of rainwater itself as a triggering power source. When it rains lightly, the collection trough and the water tank can drain in an orderly manner without affecting the operation of the equipment. When it rains heavily, the water level in the water tank rises and the hydraulic reset bottom plate triggers a series of interlocking transmissions. Finally, the power of the motor is switched to the threaded rod through the bevel gear set and the meshing block to realize the recovery of the monitoring end. After the recovery is completed, the idling mechanism is used to avoid power overload. After the rain stops, the water level of the water tank drops, the compression spring pushes the mechanism to reset and the bevel gear switches the meshing relationship, driving the monitoring end to extend again and resume work. This not only effectively protects the precision sensors inside the monitoring end from rain erosion and interference, but also realizes environmental adaptive control through purely mechanical means, improving the reliability, durability and environmental adaptability of the system.

[0016] The carbon emission monitoring device of this highway project drives the peristaltic handle and the peristaltic wheel to squeeze the peristaltic tube synchronously by rotating the upper bevel gear. On the one hand, it pushes air into the bent tube to promote liquid circulation. On the other hand, it automatically draws rainwater from the water tank as a cooling medium through negative pressure. 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 carries the heat away through the return pipe through the flow of liquid, forming a continuous and effective cooling cycle. It not only solves the measurement drift and life shortening problems caused by overheating of optical and electronic components, but also makes full use of rainwater resources to realize closed-loop utilization of energy and resources, and improves the measurement accuracy and stability of the system in high temperature environments.

[0022] The threaded rod 52 is rotatably connected to the outer shell 1, and a transverse rod is fixedly connected to the top of the inner wall of the outer shell 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 shell 1, and the four exhaust channels 54 are fixedly connected to the monitoring end 51. The inner wall of the monitoring gas groove 57 is provided with a filter, and the rack 56 is fixedly connected to the inner wall of the outer shell 1. A square groove is provided on the bottom surface of the outer shell 1, and the square groove corresponds to the position of the lower through groove 510. A plurality of drainage holes are provided 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 shell 1, and pushes the photovoltaic panel 4 to flip upward around the connection of the collection tank 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. In order to continuously provide electric energy to the inside of the monitoring terminal 51, the monitoring terminal 51 uses the collection cover 55 set on the side to make the temperature sensor, humidity sensor, and gas sensor set in the collection cover 55 perform item-by-item processing on the carbon emissions of the surrounding environment through the monitoring gas slot 57 opened in the collection cover 55, and 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 of optical equipment such as infrared absorption method and the error caused by measuring temperature changes. By measuring humidity, it avoids water molecules absorbing infrared light of a specific wavelength, which affects the measurement accuracy of CO2 and CH4 methane and reduces interference. In addition, by measuring data separately through the collection covers 55 set at different positions, it can avoid cross interference caused by close distance and affect the monitoring The monitoring end 51 is driven to retract into the housing 1 by rotating the threaded rod 52 when the external environment is in an environment not suitable for monitoring, such as heavy rain or strong wind.

[0023] The storage mechanism 6 includes a water leakage baffle 61, which is fixedly connected to the inner wall of the collecting tank 3. The inner wall of the water tank 2 is slidably connected to a reset bottom plate 62. The bottom surface of the reset bottom plate 62 is fixedly connected to a rotating shaft frame 63. The internal rotation of the rotating shaft frame 63 is connected to a rotating shaft rod 67. The upper and lower ends of the rotating shaft rod 67 are respectively fixedly connected to the upper bevel gear 64 and the lower bevel gear 65. The bottom surface of the rotating shaft rod 67 is slidably connected to a vertical sliding rod 66. The side of the lower bevel gear 65 is meshed with a side bevel gear 68. The axis of the side bevel gear 68 is fixedly connected with a meshing block 610. The outer side of the meshing block 610 is rotatably connected to a rotating drum 69. A fitting block 611 is provided on the side of the meshing block 610 away from the side bevel gear 68.

When it rains lightly, rainwater falls into the collection tank 3 and flows into the water tank 2 through the leaking partition 61 in the collection tank 3. When a certain amount of rainwater accumulates, it will pass through the water tank 2, the drainage holes on the side of the water tank 2 will drain the excess water. When it is in a heavy rain or rainstorm environment, the rainwater will quickly replenish into the collection tank 3 and flow from the collection tank 3 through the leaking partition 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 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 the vertical slide bar 66 will be pressed by the rotating shaft rod 67 connected to the rotating shaft frame 63, so that the compression spring between the upper tray 613 and the lower tray 614 is compressed. The continuously working motor 8 drives the vertical slide bar 66 to rotate, and the vertical slide bar 66 is driven by the outer spline to the rotating shaft rod 67. At this time, the rotating shaft frame 63 moves down together with the rotating shaft rod 67 and The upper bevel gear 64 is driven to mesh with the side bevel gear 68, and the upper bevel gear 64 transmits the side bevel gear 68, so that the side bevel gear 68 rotates to drive the meshing block 610 to rotate, and the meshing block 610 drives the meshing fitting block 611, and transmits the threaded rod 52 through the horizontal sliding rod 612 connected to the fitting block 611. At this time, the threaded rod 52 rotates to drive the monitoring end 51 to be stored back into the housing 1. When the monitoring end 51 is fully stored, the monitoring end 51 is stuck with the threaded rod 52 and no longer rotates. At this time, the continuous rotation of the side bevel gear 68 will drive the meshing block 610 to be in an idling state. The idling meshing block 610 will push the fitting block 611 to squeeze the elastic spring and allow the fitting block 611 to slide with the axis of the threaded rod 52 through the spline outside the connected horizontal sliding rod 612. After the rain stops,After the water level in the trough 2 is discharged through the drain hole, it drops. At this time, the gravity above the reset bottom plate 62 is reduced, and the compression spring pushes the upper tray 613, the shaft rod 67 and the shaft frame 63 to reset. The shaft frame 63 moves up to drive the lower bevel gear 65 to engage with the side bevel gear 68. At this time, the side bevel gear 68 rotates in the opposite direction to drive the meshing block 610 to rotate. After the meshing block 610 is engaged with the fitting block 611, the horizontal sliding rod 612 drives the threaded rod 52 to rotate, so that the monitoring end 51 extends outward from the inside of the housing 1. The whole process does not require manual intervention or additional sensor control. Through the ingenious mechanical structure, the gravity of the rainwater itself is used as the trigger power source. When it rains lightly, the collection tank 3 and the trough 2 can drain in an orderly manner. This does not affect the operation of the equipment. During heavy rain, the water level in the trough 2 rises, hydraulically pushing the reset base plate 62 to trigger a series of interlocking transmissions. Ultimately, the bevel gear set and meshing block 610 switch the power of the motor 8 to the threaded rod 52, enabling the monitoring terminal 51 to be recovered. After the recovery is complete, the idling mechanism is used to prevent power overload. After the rain stops, the water level in the trough 2 drops, the compression spring pushes the mechanism to reset, and the bevel gears switch meshing, driving the monitoring terminal 51 to re-extend and resume operation. This not only effectively protects the precision sensors inside the monitoring terminal 51 from rainwater erosion and interference, but also achieves environmental adaptive control through purely mechanical means, improving the system's reliability, durability, and environmental adaptability.

[0024] The heat dissipation mechanism 7 includes two peristaltic handles 71, and the inner side of each peristaltic handle 71 is rotatably connected to three peristaltic wheels 72. The outer side of the peristaltic wheel 72 is provided with a peristaltic tube 73. The end of the peristaltic tube 73 is fixedly connected to a bending tube 74. The end of the bending tube 74 away from the peristaltic tube 73 is fixedly connected to a heat dissipation tube 75. The end of the heat dissipation tube 75 away from the bending tube 74 is fixedly connected to a return pipe 76. The peristaltic tube 73 is fixedly connected to the top surface of the reset base plate 62. The peristaltic handle 71 The axis of the upper bevel gear 64 is fixedly connected, 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, and the return pipe 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, the upper bevel gear 64 will drive the coaxial peristaltic handle 71 to rotate and 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, and the peristaltic tube 73 is in a negative pressure state. The liquid in the water tank 2 will be extracted to balance the negative pressure, and 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 heat will be taken away through the return pipe 76 by the flow of liquid in the heat dissipation pipe 75. The upper bevel gear 64 rotates to synchronously drive 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 extracted as a cooling medium through negative pressure. 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 takes the heat away through the return pipe 76 through the flow of liquid, forming a continuous and effective cooling cycle. It not only solves the measurement drift and life shortening problems of optical and electronic components caused by overheating, 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.

[0025] Working principle: When the threaded rod 52 rotates, the threaded rod 52 pushes the monitoring end 51 to extend outward from the inside of the shell 1, and the monitoring end 51 moves outward from the inside of the shell 1 to push the photovoltaic panel 4 to flip upward around the connection of the collection tank 3, so that the photovoltaic panel 4 can be laid flat to continuously provide power to the inside of the monitoring end 51. At this time, the monitoring end 51 uses the collection cover 55 set on the side to make the temperature sensor, humidity sensor, and gas sensor set in the collection cover 55 to perform sub-item processing on the carbon emissions of the surrounding environment through the monitoring gas slot 57 opened in the collection cover 55, and the measured data is transmitted to the built-in analysis module of the monitoring end 51. The analysis module integrates the obtained data and reduces the baseline drift of optical equipment such as infrared absorption method by measuring temperature changes, thereby producing Errors are generated by measuring humidity to avoid water molecules absorbing infrared light of a specific wavelength, which affects the measurement accuracy of CO2 and CH4 methane and reduces interference. In addition, by measuring data separately through the collection covers 55 set at different positions, cross interference caused by close distances can be avoided, which affects the monitoring results. When the external environment is in an environment that is not suitable for monitoring, such as heavy rain or strong wind, the monitoring end 51 is driven to retract into the inside of the shell 1 by rotating the threaded rod 52. At this time, the toothed ring 58 on the outside of the collection cover 55 gradually approaches and engages with the rack 56. The toothed ring 58 engaged with the rack 56 will rotate with the movement of the monitoring end 51, and the rotating toothed ring 58 drives the rotating drum 69 to clean the dust attached to the filter in the monitoring gas tank 57, so as to avoid dust adhering to the filter and causing the monitoring gas tank 57 to The monitoring effect is affected by the blockage. In addition, the monitoring end 51 is used to move and squeeze the folded airbag 53, so that the gas in the folded airbag 53 is pressurized and discharged through the exhaust channel 54 to blow off the dust outside the collection cover 55, and the blown dust is discharged downward through the lower through groove 510. When the threaded rod 52 rotates to push the monitoring end 51 to extend, it can not only automatically lift and flatten the photovoltaic panel 4 to continuously supply power, but also expose the collection cover 55 on the side of the monitoring end 51 to the environment. The internal multi-sensor temperature, humidity, and gas are used to monitor the gas groove 57 for the sub-item collection of environmental parameters and carbon emissions. By measuring the temperature and humidity data in real time and inputting them into the built-in analysis module, the baseline drift of the optical equipment caused by temperature changes and the infrared spectrum interference caused by water vapor absorption can be dynamically compensated. , significantly improving the accuracy and anti-interference ability of measuring gases such as CO2 and CH4. The distribution of multiple collection covers 55 avoids cross-interference between sensors. In bad weather, the threaded rod 52 rotates in the opposite direction to drive the monitoring end 51 to retract into the shell 1. At this time, the gear ring 58 and the rack 56 engage and rotate, driving the rotating drum 69 to clean the dust on the filter screen to prevent the air groove from being blocked. At the same time, the contraction action squeezes the folded air bag 53, forming an airflow to sweep the surface of the collection cover 55 and discharge dust through the lower groove 510, realizing self-cleaning and dust-proof protection of key components. The overall system has a compact structure and efficient operation. Without the need for external power, only one set of driving mechanism can simultaneously complete the functions of monitoring unit deployment, power supply guarantee, environmental compensation, contraction protection and linkage self-cleaning.The reliability, adaptability and maintenance efficiency of the monitoring system have been greatly improved; When it rains lightly, rainwater falls into the collecting trough 3 and flows into the water trough 2 through the leaking baffle 61 in the collecting trough 3. When a certain amount of rainwater accumulates, the excess water will be discharged through the drainage holes on the side of the water trough 2. When it rains heavily or rainstorms, the rainwater will quickly replenish the collecting trough 3 and flow from the collecting trough 3 through the leaking baffle 61 into the water trough 2. At this time, the discharge rate of the drainage holes on the side of the water trough 2 is lower than the rate of rainwater flowing into the water trough 2, which will increase the water level in the water trough 2 and increase the pressure on the reset bottom plate 62 in the water trough 2. At this time, the reset bottom plate 62 will squeeze the rotating shaft frame 63 at the bottom, and then press the vertical sliding rod 66 through the rotating shaft rod 67 connected to the rotating shaft frame 63, so that the compression spring between the upper tray 613 and the lower tray 614 is compressed, and the water continues to work. The motor 8 drives the vertical slide bar 66 to rotate, and the vertical slide bar 66 transmits the rotation shaft 67 through the outer spline. At this time, the shaft frame 63 moves down together with the rotation shaft 67 and drives the upper bevel gear 64 to engage with the side bevel gear 68. The upper bevel gear 64 transmits the side bevel gear 68, so that the side bevel gear 68 rotates and drives the meshing block 610 to rotate. The meshing block 610 drives the meshing fitting block 611 and transmits the threaded rod 52 through the horizontal slide bar 612 connected to the fitting block 611. At this time, the threaded rod 52 rotates and drives the monitoring end 51 to be stored back into the housing 1. When the monitoring end 51 is fully stored, the monitoring end 51 is stuck with the threaded rod 52 and no longer rotates. At this time, the continuous rotation of the side bevel gear 68 will drive the meshing block 610 to be in an idling state. The meshing block 610 in the idling state The engagement block 611 will be pushed to squeeze the elastic spring, and the engagement block 611 will slide with the axis of the threaded rod 52 through the spline outside the connected horizontal sliding rod 612. After the rain stops, the water level in the water tank 2 is discharged through the drain hole and then drops. At this time, the gravity above the reset bottom plate 62 is reduced, and 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 to drive the engagement block 610 to rotate. After the engagement block 610 and the engagement block 611 are engaged, the horizontal sliding rod 612 drives the threaded rod 52 to rotate, so that the monitoring end 51 extends outward from the inside of the housing 1. The entire process does not require manual intervention or additional sensor control, and uses the rainwater's own weight through an ingenious mechanical structure. The force 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 the operation of the equipment. When it rains heavily, the water level in the water tank 2 rises and the hydraulic pressure pushes the reset bottom plate 62 to trigger a series of linkage transmissions. Finally, the power of the motor 8 is switched to the threaded rod 52 through the bevel gear set and the meshing block 610 to realize the recovery of the monitoring end 51. After the recovery is completed, the idling mechanism is used to avoid power overload. After the rain stops, the drainage water level of the 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 re-extend and resume work. This not only effectively protects the precision sensor inside the monitoring end 51 from rain erosion and interference, but also realizes environmental adaptive control in a purely mechanical way, thereby improving the reliability, durability and environmental adaptability of the system. When the upper bevel gear 64 rotates, the upper bevel gear 64 will drive the coaxial peristaltic handle 71 to rotate and 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, and the peristaltic tube 73 is in a negative pressure state and the liquid in the water tank 2 is extracted to balance the negative pressure. The liquid in the bent tube 74 will pass into the heat dissipation pipe 75, and the heat generated inside the monitoring end 51 will be absorbed by the heat dissipation pipe 75. At the same time, the heat will be taken away through the reflux pipe 76 by the flow of liquid in the heat dissipation pipe 75. The upper bevel gear 64 rotates synchronously to drive 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 bent tube 74 to promote liquid circulation. On the other hand, rainwater in the water tank 2 is automatically extracted as a cooling medium through negative pressure. 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 terminal 51 and removes the heat through the return pipe 76 through the flow of liquid, forming a continuous and effective cooling cycle. This not only solves the measurement drift and life shortening problems 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.

When the external environment is in an environment not suitable for monitoring, such as heavy rain or strong wind, the monitoring end 51 is retracted into the inside of the shell 1 by rotating the threaded rod 52. At this time, the toothed ring 58 on the outside of the collection cover 55 gradually approaches and engages with the rack 56. The toothed ring 58 engaged with the rack 56 will rotate with the movement of the monitoring end 51. The rotating toothed ring 58 drives the rotating drum 69 to clean the dust attached to the filter screen in the monitoring gas tank 57, so as to avoid dust adhering to the filter screen and causing the monitoring gas tank 57 to be blocked, thereby affecting the monitoring effect; S4: The monitoring end 51 is moved to squeeze the folded airbag 53, so that the gas in the folded airbag 53 is compressed and discharged through the exhaust channel 54, blowing off the dust outside the collection cover 55. The blown dust is discharged downward through the lower through groove 510. When the threaded rod 52 rotates and pushes the monitoring end 51 to extend, it not only automatically lifts up the photovoltaic panel 4 and lays it flat to continuously supply power, but also exposes the collection cover 55 on the side of the monitoring end 51 to the environment; When the water level in the water tank 2 increases, the pressure on the reset bottom plate 62 in the water tank 2 increases. At this time, the reset bottom plate 62 squeezes the rotating shaft frame 63 at the bottom, and then applies pressure to the vertical slide bar 66 through the rotating shaft rod 67 connected to the rotating shaft frame 63, so that the compression spring between the upper tray 613 and the lower tray 614 is compressed. The continuously working motor 8 drives the vertical slide bar 66 to rotate. The vertical slide bar 66 transmits the rotating shaft rod 67 through the outer spline. The threaded rod 52 rotates and drives the monitoring end 51 to be stored inside the shell 1. When the monitoring end 51 is fully stored, the monitoring end 51 is stuck in the threaded rod 52 and no longer rotates. At this time, the continuous rotation of the side bevel gear 68 drives the meshing block 610 to be in an idling state. The meshing block 610 in the idling state pushes the fitting block 611 to squeeze the elastic spring and allow the fitting block 611 to slide with the axis of the threaded rod 52 through the spline outside the connected horizontal slide bar 612.

The peristaltic tube 73 is in a negative pressure state and 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, and the heat dissipation pipe 75 will absorb the heat generated inside the monitoring end 51. At the same time, the heat will be taken away through the reflux pipe 76 by the flow of liquid in the heat dissipation pipe 75.
