Description

Technical Field

[0001] This utility model is a mobile carbon emission monitoring device, belonging to the field of carbon emission monitoring. Background Technology

[0002] With the upgrading of industrial production and environmental supervision, carbon emission monitoring is gradually evolving from fixed-point monitoring to dynamic mobile monitoring. Mobile monitoring devices, which can cover multiple scenarios such as workshops, factories, and outdoors, have become the core equipment for accurate measurement of carbon emissions.

[0003] Existing carbon emission monitoring devices are mostly fixed in place and typically employ a "fixed height + single air inlet" design. This fixed placement prevents them from being moved, with the collection port directly fixed to the top or side of the device at a non-adjustable height. They can only collect gas at a specific height. However, in real-world scenarios, carbon emissions exhibit significant spatial distribution differences. For example, in factory workshops, high-temperature gases emitted by equipment may diffuse upwards, while leaked low-temperature gases may accumulate on the ground. In outdoor environments, CO2 concentrations near vegetation and in open areas also differ at different heights. Fixed-height collection structures cannot capture these vertical concentration gradients, leading to incomplete monitoring data. Furthermore, traditional collection mechanisms have narrow air inlet ranges, often consisting of a single-diameter inlet pipe or a small gas hood, only collecting gas from directly in front of the device or a localized area. During mobile monitoring, the device's direction of travel may deviate from the gas diffusion direction, making it difficult for a single air inlet structure to cover gas samples from multiple lateral directions. Especially in complex environments such as densely populated equipment areas in workshops or warehouse corners, dead zones in gas flow can easily lead to missed detections, failing to reflect the overall carbon emission level of the monitored area. Therefore, designing a mobile carbon emission monitoring device is essential. Utility Model Content

[0014] Furthermore, a control panel is provided at one end of the protection box, the power plug is inserted into the power port at the bottom of the protection box, and the output end of the battery pack is rigidly electrically connected to the input end of the power plug through copper conductive terminals.

[0015] Furthermore, the gas collection mechanism includes a servo motor, a limiting cylinder, a gas collection component, a lifting cylinder, and an air inlet pipe. The limiting cylinder passes through the center of the top of the protective box, and a lifting cylinder is provided inside the limiting cylinder. The top of the lifting cylinder extends out of the limiting cylinder and is connected to the gas collection component. An air inlet pipe is provided inside the lifting cylinder, and the bottom of the air inlet pipe passes through the bottom of the lifting cylinder and is rotatably connected to the air extraction end at the top of the air pump.

[0016] Furthermore, the monitoring component includes a housing, a non-dispersive infrared sensor, and an NB-IoT module, and the monitoring component is plugged into the protective box.

[0017] Furthermore, the gas sampling assembly includes a main pipe, branch pipes, air inlet hoppers, and threaded connecting sleeves.

The inner surface of the lifting cylinder is vertically provided with a groove that matches the limiting ridges.

[0019] The beneficial effects of this utility model are:

[0020] 1. Existing devices are fixed in place and cannot be moved on their own, thus limiting their monitoring range. This application empowers the device with autonomous movement through a tracked walking mechanism. With the steering control of the differential motor, it can flexibly move between various scenarios such as workshops, factories, and outdoors. It can complete continuous monitoring of different areas without manual handling, solving the problem of blind spots in the "single-point static" monitoring of traditional devices and greatly improving the flexibility and efficiency of monitoring coverage.

[0021] 2. To address the issue of "data bias caused by fixed height" in existing devices, the gas collection mechanism can flexibly switch between two modes to suit different monitoring targets in different scenarios: When precise monitoring of carbon emissions at a specific height is required, such as the height of the equipment exhaust port, the gas collection component can be fixed at the corresponding height by a servo motor to ensure the specificity of the collected data; during mobile monitoring, the device can control the gas collection component to rotate and rise simultaneously—the drive tube rotates, causing the lifting cylinder to change height while rotating, allowing the gas collection component to continuously collect gas within a 360° horizontal range and a fully adjustable vertical range. This dynamic collection mode can automatically integrate gas samples from different heights and orientations to calculate the average carbon emission value of the monitoring area, avoiding local data deviations caused by a single height or fixed angle, and more scientifically reflecting the overall emission level of the area.

[0022] 3. The gas sampling assembly adopts a "multi-branch pipe + multi-inlet bucket" design, which has a wide coverage range. Even if there is a deviation between the direction of travel of the device and the direction of gas diffusion during mobile monitoring, the multi-directional air intake structure can still capture gas samples from different lateral areas.

[0049] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0050] Please see Figures 1 to 6 This utility model provides a technical solution: a mobile carbon emission monitoring device, including a tracked walking mechanism 1. The tracked walking mechanism 1 includes a carrier plate 102, track assemblies 101 symmetrically arranged on both sides of the carrier plate 102, and two differential motors 103. A top plate 2 is installed above the carrier plate 102, and a power connector 9 is provided at the center of the top of the top plate 2. A battery pack 8 is disposed in the cavity between the carrier plate 102 and the top plate 2. Spring dampers 3 are connected to the four corners of the bottom of the mounting plate 4, and the bottom of the spring dampers 3 is fixedly connected to the top plate 2 to protect the device. Box 6 is located at the top center of mounting plate 4. An air pump 12 is installed in the center of the inside of box 6, and the air outlet of the air pump 12 is connected to a monitoring component 13. An air collection mechanism 7 is located through the top center of box 6, and the air outlet of the air collection mechanism 7 is rotatably connected to the air inlet of the air pump 12. The track walking mechanism 1 adopts a symmetrical design of "carrier plate 102 + track components 101 on both sides", and is independently driven by differential motor 103. It can enhance ground grip through the large contact area of ​​track components 101, and can also achieve flexible steering by utilizing the speed difference between the two sides.

[0051] Please see Figure 1 and Figure 2The track assembly 101 includes a frame, guide wheels, drive pulleys, suspension brackets, support rollers, mounting brackets, carrier rollers, and a drive track. The frame is fixedly connected to the side wall of the carrier plate 102, and guide wheels and drive pulleys are rotatably connected to both ends of the frame, respectively. A suspension bracket is installed at the center of the bottom of the frame, and multiple support rollers are evenly spaced at the bottom of the suspension bracket. The support rollers are rotatably connected to the suspension bracket, and the support rollers are elastically connected to the frame through the suspension bracket. A mounting bracket is slidably connected to the center of the top of the frame, and carrier rollers are rotatably connected to both sides of the top of the mounting bracket. The drive track is arranged around the outside of the guide wheels, drive pulleys, support rollers, and carrier rollers. Furthermore, the transmission track has equally spaced transmission grooves that mesh with the drive pulleys. Differential motors 103 are installed at the top of the carrier plate 102 near the drive pulleys, and the output ends of the two differential motors 103 are respectively connected to the drive pulleys of the two track assemblies 101. The track assembly 101 adopts a multi-wheel combination structure of "guide wheel + drive pulley + support roller + carrier roller": the drive pulley directly transmits the power of the differential motor 103 to the track by meshing with the transmission grooves on the transmission track, avoiding the power loss of traditional friction transmission; the guide wheel guides the track direction, the carrier roller supports the top of the track to prevent sagging, and the support roller bears the weight of the device and reduces the ground pressure of the track.

[0052] Please see Figure 2 and Figure 3 The mounting plate 4 has four connecting bolts 5 at the top corners, and the spring damper 3 has a threaded connection groove 301 at the top. The bottom of the connecting bolt 5 passes through the mounting plate 4 and is threadedly connected to the threaded connection groove 301. The mounting plate 4 is rigidly fixed to the spring damper 3 by the connecting bolts 5 at the four corners and the threaded connection groove 301. The four-point symmetrical connection structure can evenly distribute the weight of the mounting plate 4 and the upper protective box 6 to the four spring dampers 3. The spring damper 3 can absorb vibration energy through its own elastic deformation, convert high-frequency vibration into slow elastic expansion and contraction, greatly reduce the vibration amplitude transmitted to the protective box 6, ensure that the monitoring component 13 operates in a stable environment, and ensure the accuracy of carbon emission data.

[0053] Please see Figure 2 and Figure 3 One end of the protection box 6 is equipped with a control panel 16. The power plug 9 is plugged into the power port at the bottom of the protection box 6. The output end of the battery pack 8 is rigidly connected to the input end of the power plug 9 through copper conductive terminals. The control panel 16 at one end of the protection box 6 centrally integrates the operation control functions of the device. The operator can complete the input of various commands without touching the internal components, which simplifies the operation process and avoids accidental contact with the air pump 12, monitoring components 13 and other precision components inside the protection box 6, thereby improving the safety and efficiency of operation.

[0054] Please see Figure 1 and Figure 4 The gas collection mechanism 7 includes a servo motor 11, a limiting cylinder 14, a gas collection component 15, a lifting cylinder 17, and an air inlet pipe 18. The limiting cylinder 14 passes through the center of the top of the protective box 6, and the lifting cylinder 17 is installed inside the limiting cylinder 14. The top of the lifting cylinder 17 extends out of the limiting cylinder 14 and connects to the gas collection component 15. The air inlet pipe 18 is installed inside the lifting cylinder 17, and the bottom of the air inlet pipe 18 passes through the bottom of the lifting cylinder 17 and is rotatably connected to the suction end of the top of the suction pump 12. The limiting cylinder 14 provides vertical guidance for the lifting cylinder 17, so that the lifting cylinder 17 can rise and fall stably along the limiting cylinder 14, thereby driving the gas collection component 15 at the top to achieve height adjustment. This design breaks through the limitation of the traditional gas collection structure of "fixed height", and can accurately adjust the gas collection position according to monitoring needs, capture the carbon emission concentration differences in different vertical dimensions, and improve the comprehensiveness of monitoring data.

[0055] Please see Figure 3 and Figure 6 The monitoring component 13 includes a housing 1301, a non-dispersive infrared sensor 1303, and an NB-IoT module 1304. The monitoring component 13 is plugged into the protective box 6. The non-dispersive infrared sensor 1303 and the NB-IoT module 1304 are respectively installed at both ends inside the housing 1301. An air inlet 1302 connected to the output end of the air pump 12 is provided at the center of one end of the housing 1301. A filter screen 1305 is provided at the other end of the housing 1301. After the gas delivered by the air pump 12 enters the housing 1301 through the air inlet 1302, the non-dispersive infrared sensor 1303 can directly detect the CO2 concentration. The detection data is uploaded to the terminal in real time through the NB-IoT module 1304 without the need for additional transmission cables, reducing signal loss and interference, and ensuring the timeliness and accuracy of data transmission.

[0056] Please see Figure 5The gas sampling assembly 15 includes a main pipe 1501, branch pipes 1502, air inlets 1503, and threaded connecting sleeves 1504. Multiple branch pipes 1502 are arranged radially and at equal angles along the outer periphery of the main pipe 1501, and multiple air inlets 1503 are evenly arranged on each branch pipe 1502. A threaded connecting sleeve 1504 is integrally provided at the bottom of the main pipe 1501. A threaded connector 1703 that mates with the threaded connecting sleeve 1504 is provided at the top of the lifting cylinder 17. The outer diameter of the lifting cylinder 17 matches the inner diameter of the limiting cylinder 14. A spiral groove 1702 is formed on the outer surface of the lifting cylinder 17. A limiting bolt 1401 is installed at the center of the top of one end of the limiting cylinder 14, with the end of the limiting bolt 1401 inserted into the spiral groove 1702. Multiple branch pipes 1502 are arranged radially and at equal angles along the outer periphery of the main pipe 1501. The pipe 1502 has multiple air intake hoppers 1503 evenly distributed on it, forming a "radial + multi-point" air intake structure. This design can simultaneously collect gas samples from different lateral directions. Especially in workshops with dense equipment or outdoor environments with complex gas diffusion, it can reduce sampling deviations caused by uneven gas distribution and improve the representativeness of the overall carbon emission level of the monitoring area. The spiral groove 1702 and the insertion design of the limit bolt 1401 on the outer surface of the lifting cylinder 17 allow the lifting cylinder 17 to rise and fall stably along the limit cylinder 14 and rotate through the relative movement of the spiral groove 1702 and the limit bolt 1401. This "lifting + rotation" composite movement allows the air intake hopper 1503 to cover a wider area in both vertical and horizontal directions, further enhancing the comprehensiveness of gas sampling.

[0057] Please see Figure 4 and Figure 5The intake pipe 18 includes a connecting pipe 1801, a secondary bevel gear 1802, and a drive pipe 1803. The bottom of the connecting pipe 1801 is rotatably connected to the suction end of the top of the suction pump 12, and the secondary bevel gear 1802 is fixed to the outside of the connecting pipe 1801. A servo motor 11 is mounted on the end of the protective box 6 away from the monitoring component 13 via a bracket 10, and the output end of the servo motor 11 is connected to a main bevel gear 1101 that meshes with the secondary bevel gear 1802. The top of the connecting pipe 1801 passes through the bottom of the limiting cylinder 14 and is integrally connected to the drive pipe 1803. The drive pipe 1803 extends into the lifting cylinder 17, and the outer diameter of the drive pipe 1803 matches the inner diameter of the lifting cylinder 17. Four limiting ribs 1804 are evenly spaced along the axial direction on the outer surface of the drive pipe 1803. The inner surface of the 7 is vertically provided with a groove 1701 that matches the limiting edge 1804. The meshing accuracy of the main bevel gear 1101 and the secondary bevel gear 1802, combined with the stepless speed regulation function of the servo motor 11, can precisely adjust the lifting height and rotation angle of the lifting cylinder 17 by controlling the rotation speed and number of revolutions of the drive tube 1803, so as to achieve precise positioning of the gas sampling component 15 at different positions. The limiting edge 1804 on the outer surface of the drive tube 1803 and the groove 1701 on the inner surface of the lifting cylinder 17 are precisely matched to form a "rigid linkage" structure: when the drive tube 1803 rotates under the drive of the servo motor 11, the limiting edge 1804 is embedded in the groove 1701, forcibly driving the lifting cylinder 17 to rotate synchronously; at the same time, the groove 1701 is opened in the vertical direction to provide guidance for the lifting movement of the lifting cylinder 17.

[0058] Detailed implementation: The movement of the device is driven by the track walking mechanism 1: The track assemblies 101 on both sides of the carrier plate 102 are driven independently by the differential motor 103, and move by contacting the ground through the transmission track. The speed difference between the two sides completes the steering. The battery pack 8 is placed in the cavity between the carrier plate 102 and the top plate 2, and supplies power to each component through the power connector 9.

[0059] During the movement, the spring damper 3 at the bottom of the mounting plate 4 absorbs the vibration and reduces the impact on the internal components of the protective box 6. Inside the protective box 6, the gas collection mechanism 7, the air pump 12, and the monitoring component 13 form a detection link: the servo motor 11 drives the main bevel gear 1101, which meshes with the secondary bevel gear 1802 to drive the drive pipe 1803 of the air intake pipe 18 to rotate. The drive pipe 1803 is embedded in the groove 1701 of the lifting cylinder 17 through the limiting rib 1804, so that the lifting cylinder 17 rises and falls and rotates along the limiting cylinder 14. The branch pipe 1502 and the air intake bucket 1503 of the gas collection component 15 collect gas from multiple directions and send it to the air pump 12 through the main pipe 1501 and the lifting cylinder 17.

[0060] The vacuum pump 12 pressurizes the gas into the monitoring component 13. The non-dispersive infrared sensor 1303 inside the housing 1301 detects the CO2 concentration. The data is transmitted through the NB-IoT module 1304, and the gas is discharged from the filter 1305.
