Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission collection, and specifically to a data collection device for verifying carbon emissions in urban road traffic. Background Art

[0002] In a Chinese patent with the patent publication number CN221506413U, a carbon emission collection device is disclosed, which includes a box body. A detection mechanism is provided inside the box body. The front end of the detection mechanism is connected to a suction mechanism, and the suction mechanism is located inside the box body. A filter plate is provided at the front end of the box body, and the filter plate is located in front of the suction mechanism. The front end of the filter plate is connected to a cleaning mechanism, and the cleaning mechanism is connected to the front end of the box body. The box body is connected to the upper end of a base through a positioning plate, and an installation plate is connected to the rear end of the base. The device body is installed beside the road through the installation plate. The detection mechanism inside the box body sucks external air through the suction mechanism. The filter plate provided at the front end of the box body prevents foreign objects from entering, and the cleaning mechanism connected to the outside of the filter plate is used for cleaning, so that the filter holes of the filter plate will not be blocked, facilitating the absorption of the suction mechanism.

[0003] However, the above patent still has the following defects during specific use: 1. In the above patent, although the cleaning function of the filter plate surface has been realized, the cleaning mechanism adopts a motor drive method. This method not only requires continuous power supply during use, but also under special strong wind and harsh weather conditions, such as power supply abnormalities or interruptions, the cleaning mechanism may not be able to clean the filter plate surface in a timely and effective manner. Since the wind will blow dust and impurities into the air, if the filter plate surface cannot be cleaned in time, the filter plate is likely to be blocked due to failure to be cleaned in time, thus affecting its normal operation.

[0004] 2. In addition, when performing carbon emission detection on the road, when a vehicle quickly passes under the collector, due to the weight and driving speed of the vehicle itself, a large amount of kinetic energy and impact force will be generated. This kinetic energy and impact force will act on the road surface and be transmitted to the collector through the road surface. If the collector is usually fixed on a support rod above the road, the shaking may cause the sensors inside the collector to shift or deviate. Since the sensors need to maintain a stable position and state to accurately measure carbon emission data, it will affect the accuracy of data collection.

[0005] Therefore, a data collection device for verifying carbon emissions in urban road traffic is proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to provide a device for collecting urban road traffic carbon emission verification data, so as to solve the problem that the collector is easily interfered by vibration during carbon emission collection and detection of vehicles in special environments and traffic jams.

[0007] To achieve the above object, the present invention provides the following technical solution: A device for collecting urban road traffic carbon emission verification data, including a protective cover, on the upper end of which a wind monitor is installed, in the middle of which a carbon emission collector is installed, and at the bottom of which an L-shaped fixing block is provided. It also includes an automatic dust removal and flow blocking mechanism and a multi-functional protection mechanism. The automatic dust removal and flow blocking mechanism is arranged on the carbon emission collector, and the multi-functional protection mechanism is arranged at the bottom of the protective cover; The automatic dust removal and flow blocking mechanism is used for wind collection and dust prevention of the carbon emission collector; The multi-functional protection mechanism is used for shock absorption and anti-vibration of the protective cover.

[0008] Preferably, the automatic dust removal and flow blocking mechanism includes a V-shaped flow blocking plate, in the middle of the upper end of which an inclined angle extrusion groove is opened, and on both sides of the upper end of which a guiding groove is rotatably connected. One end of the guiding groove away from the V-shaped flow blocking plate is fixedly connected to the carbon emission collector.

[0009] Preferably, a cleaning swing rod is rotatably connected in the inclined angle extrusion groove. One end of the cleaning swing rod away from the inclined angle extrusion groove is provided with a cleaning plate, and above the cleaning plate is provided a second filter plate, which is fixedly connected to the gas collection port of the carbon emission collector.

[0010] Preferably, a first filter plate is fixedly connected to the bottom of the carbon emission collector, and the filter holes opened in the first filter plate are larger than those opened in the second filter plate.

[0011] Preferably, the multi-functional protection mechanism includes a pressing plate, one end of which is rotatably connected to the bottom of the protective cover, and the other end of which is rotatably connected to a T-shaped block, and the bottom of the T-shaped block is slidably connected to the upper surface of the L-shaped fixing block.

[0012] Preferably, the multi-functional protection mechanism further includes a fixed shaft, both ends of which are fixedly connected to the upper surface of the L-shaped fixing block. The T-shaped blocks are symmetrically slidably connected to the outer surface of the fixed shaft, and a buffer spring is sleeved on the outer surface of the middle of the fixed shaft, and both ends of the buffer spring are fixedly connected to the T-shaped blocks.

[0013] Preferably, a reset spring is evenly arranged on the upper surface of the L-shaped fixing block and close to the lower part of the T-shaped block. One end of the reset spring is fixedly connected to the L-shaped fixing block, and the other end of the reset spring is fixedly connected to an L-shaped clamping plate, and the bottom of the L-shaped clamping plate is slidably connected to the upper surface of the L-shaped fixing block.

[0014] Preferably, inclined grooves are symmetrically formed on the upper surface of the L-shaped clamping plate. An extrusion column is slidably connected in the inclined groove. One end of the extrusion column away from the inclined groove is fixedly connected to the bottom of the T-shaped block. A rubber plate is fixedly connected to the outer surface of the L-shaped fixing block close to the L-shaped clamping plate. The rubber plate is made of a soft rubber material.

[0015] Compared with the prior art, a data collection device for verifying urban road traffic carbon emissions provided by the present invention has the following beneficial effects: 1. Through the arrangement of the V-shaped flow blocking plate, when a vehicle passes quickly, a large amount of kinetic energy and impact force are generated by the weight and driving speed of the vehicle itself, driving the V-shaped flow blocking plate to rotate in the guiding groove. At this time, due to the action of the inclined angle extrusion groove formed on the V-shaped flow blocking plate, when the V-shaped flow blocking plate rotates, it will drive the cleaning swing rod rotatably connected in the inclined angle extrusion groove to swing in the middle of the guiding groove. When the cleaning swing rod swings, the cleaning plate of the cleaning swing rod can clean the fine dust on the outer surface of the second filter plate, preventing the blockage of the second filter plate. 2. Compared with the above patent which is driven by a motor, with the setting of the present invention, by utilizing the impact of gas, it can automatically drive the cleaning swing rod to clean the surface of the second filter plate. The design of the present invention not only ensures the stable operation of the device in bad weather, but also can drive the V-shaped flow blocking plate to perform automatic cleaning through this mechanism even in the face of wind force. It can not only effectively avoid the problems of accidental power failure and blockage of the second filter plate caused by special weather, but also ensure that the device can continuously and accurately collect data. Compared with the design in the above patent, the present invention not only greatly reduces the cost investment, but also significantly reduces the energy consumption. The design of the present invention can clean the surface of the second filter plate in real time only by relying on simple mechanical transmission, effectively preventing blockage and improving the overall performance and reliability of the device.

[0016] 3. With the V-shaped flow blocking plate arranged in a V shape, when a vehicle passes quickly, the vertical rotation of the V-shaped flow blocking plate in the guiding groove can block the air flow passing by the vehicle. Due to the blocking effect of the V-shaped flow blocking plate on the air flow when the vehicle is driving, the flow rate of the air flow will slow down, which enables the carbon emission particles in the air flow to have more sufficient time to contact the carbon emission collection and detection device above, thereby improving the accuracy of measuring the carbon emissions in the air. At the same time, with the design of the present invention, no additional power source is required, which not only increases the detection accuracy, but also greatly reduces the energy consumption, reflecting the green and environmental protection design concept.

[0017] 4. Through the setting of the multi-functional protection mechanism, when the carbon emission collector collects carbon emissions from passing vehicles, especially when the impact generated by the vehicle or strong wind weather causes the support rod to shake, at this time, the L-shaped fixing block will shake under the drive of the support rod. The extrusion of the L-shaped clamping plate and the rubber plate components in the present invention plays a key damping role. When driving the carbon emission collector to shake through the L-shaped fixing block, at this time, the extrusion column in the T-shaped block squeezes the inclined groove opened on the L-shaped clamping plate. Through the design of the present invention, the shaking influence of the support rod on the carbon emission collector of the collection equipment can be reduced, thereby greatly improving the stability of the carbon emission collector equipment during the collection process. Even when facing external environmental interference and changes, the present invention can ensure that the collected carbon emission data is more accurate and reliable.

[0021] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0022] For the embodiments, please refer to Figures 1 to 7 as shown: To solve the problems mentioned in the technical solutions, the embodiments of the present application provide a device for collecting urban road traffic carbon emission verification data, including a protective cover 1.

One end of the inclined angle extrusion groove 22 of the V-shaped flow blocking plate 21 is inclined, and both ends of the V-shaped flow blocking plate 21 are rotatably connected in the guide grooves 26. The rotation of the V-shaped flow blocking plate 21 in the guide grooves 26 can drive the cleaning swing rod 23 to swing on the surface of the second filter plate 25.

[0023] Compared with the above patent, through the implementation of this embodiment, not only the cost input is significantly reduced, but also the energy consumption is remarkably decreased. The design of the present invention can clean the surface of the second filter plate 25 in real time only by relying on simple mechanical transmission, effectively preventing blockage and improving the overall performance and reliability of the equipment.

[0024] For further embodiments, please refer to Figures 1 to 7 as shown in: The multi-functional protection mechanism 3 includes a pressing plate 31. One end of the pressing plate 31 is rotatably connected to the bottom of the protective cover 1, and the other end of the pressing plate 31 is rotatably connected to a T-shaped block 32. The bottom of the T-shaped block 32 is slidably connected to the upper surface of the L-shaped fixing block 12; The multi-functional protection mechanism 3 further includes a fixed shaft 33. Both ends of the fixed shaft 33 are fixedly connected to the upper surface of the L-shaped fixing block 12. The T-shaped blocks 32 are symmetrically slidably connected to the outer surface of the fixed shaft 33. A buffer spring 34 is sleeved on the outer surface of the middle part of the fixed shaft 33, and both ends of the buffer spring 34 are fixedly connected to the T-shaped blocks 32; Reset springs 35 are evenly arranged on the upper surface of the L-shaped fixing block 12 and close to the lower side of the T-shaped block 32. One end of the reset spring 35 is fixedly connected to the L-shaped fixing block 12, and the other end of the reset spring 35 is fixedly connected to an L-shaped clamping plate 36. The bottom of the L-shaped clamping plate 36 is slidably connected to the upper surface of the L-shaped fixing block 12; Oblique grooves 37 are symmetrically formed on the upper surface of the L-shaped clamping plate 36. Extrusion columns 38 are slidably connected in the oblique grooves 37. One end of the extrusion column 38 far from the oblique groove 37 is fixedly connected to the bottom of the T-shaped block 32. A rubber plate 39 is fixedly connected to the outer surface of the L-shaped fixing block 12 close to the L-shaped clamping plate 36, and the rubber plate 39 is made of rubber soft material; Among them: The multi-functional protection mechanism 3 is symmetrically arranged on both sides of the bottom of the carbon emission collector 11. A backup power supply is arranged in the carbon emission collector 11. When the anemometer 13 monitors strong winds in bad weather, at this time, the anemometer 13 can timely cut off the external power supply of the carbon emission collector 11 and at the same time start the internal backup power supply of the carbon emission collector 11, avoiding equipment failures or data loss caused by external power problems.

[0025] Compared with the above patent, through the implementation of this embodiment, the shaking influence of the support rod on the carbon emission collector 11 of the collection device can be reduced, thereby greatly improving the stability of the carbon emission collector 11 device during the collection process. Even in the face of interference and changes in the external environment, the present invention can ensure that the collected carbon emission data is more accurate and reliable.

[0026] The working principle of all the contents in the above embodiment is as follows: In the initial state: the cleaning rocker 23 is located on one side of the outer surface of the second filter plate 25, the return spring 35 is not compressed, the buffer spring 34 is slightly compressed and deformed under the gravity of the protective cover 1, and the bottom of the L-shaped fixing block 12 is installed on the bracket above the road.

[0027] The following is the working process of the automatic dust removal and flow blocking mechanism 2 for collecting wind and preventing dust in the carbon emission collector 11: When a device passes by a vehicle, since the vehicle itself has a certain mass and speed, it will generate interaction forces with the road surface while driving. These forces not only act on the vehicle itself, but are also transmitted to nearby devices through the road surface and the air. If the device is not fixed firmly enough, it will be easily affected by this force and shake.

[0028] On the other hand, when a car is driving, air disturbance will occur. Especially when driving at high speed, the car will form a low-pressure area. The surrounding airflow will quickly fill this area to form a complex airflow field. The airflow speed and direction in this airflow field are constantly changing, which will impact and disturb nearby equipment, causing the equipment to shake.

[0029] Since the carbon emission collector 11 is provided with a backup power supply, when the wind monitor 13 detects severe weather and strong winds, the external power supply of the carbon emission collector 11 can be cut off in time through the wind monitor 13, and the internal backup power supply of the carbon emission collector 11 can be started at the same time, thereby avoiding equipment failure or data loss caused by external power supply problems.

[0030] At this time, when the vehicle is driving fast or in bad weather, the wind will directly act on the Figure 1 On the V-shaped spoiler 21 shown, further Figure 3 As shown, when the airflow blows from the left side of the V-shaped spoiler 21, it will drive the V-shaped spoiler 21 to start rotating in the counterclockwise direction. At this time, because the upper ends of the V-shaped spoiler 21 are rotatably connected to the guide groove 26, the weight and driving speed of the vehicle itself generate greater kinetic energy and impact force to drive the V-shaped spoiler 21 to rotate in the guide groove 26. At this time, due to the effect of the oblique extrusion groove 22 provided on the V-shaped spoiler 21, when the V-shaped spoiler 21 rotates, it will drive the cleaning swing rod 23 connected to the oblique extrusion groove 22 to swing in the middle of the guide groove 26. , because the V-shaped spoiler 21 will drive the oblique extrusion groove 22 to squeeze the surface of the cleaning swing rod 23 when it rotates, and because the cleaning swing rod 23 slides in the guide groove 26 away from the outer surface of the oblique extrusion groove 22, the V-shaped spoiler 21 will rotate in the guide groove 26, and the cleaning swing rod 23 will be driven to swing in the middle of the guide groove 26 through the guiding effect of the guide groove 26. When the cleaning swing rod 23 swings, the cleaning plate of the cleaning swing rod 23 can clean the fine dust on the outer surface of the second filter plate 25, so as to prevent the second filter plate 25 from being blocked; When the V-shaped baffle 21 is arranged in a V-shape, when the vehicle passes quickly, the vertical rotation of the V-shaped baffle 21 can block the air flow passing through the vehicle in the guiding groove 26. The flow rate of the air flow will slow down under the block of the V-shaped baffle 21, which enables the carbon emission particles in the air flow to have more sufficient time to contact the detection device of the carbon emission collector 11 above, thereby improving the accuracy of measuring the carbon emission in the air. At the same time, through the design of the present invention, no additional power source is required, which not only increases the detection accuracy but also greatly reduces the energy consumption, reflecting the green and environmentally friendly design concept.

[0031] Please refer to the above working process Figures 1 to 7 。

[0032] The following is the working process of the multi-functional protection mechanism 3 for shock absorption and anti-vibration of the protective cover 1: As described above, when the carbon emission is set at different high-speed detection ports, due to the relatively high vehicle speed, when the collector is installed on the bracket above the road surface, since the extension distance of the bracket is relatively long, when the vehicle passes under the bracket at a high speed, a strong dynamic effect will be generated, and this effect is specifically manifested as the interaction force between the vehicle and the road surface, and the air flow disturbance generated when the vehicle is running; When the vehicle passes by quickly, its huge kinetic energy and speed will generate a strong impact force on the road surface in an instant. This impact force not only acts on the road surface itself but also is transmitted to the carbon emission collection device above through the road surface and the bracket. Since the extension distance of the bracket is long, it cannot effectively absorb and disperse this impact force, so the collection device will be significantly affected by shaking; At this time, the shaking of the bracket will drive the L-shaped fixing block 12 shown in Figure 1 to start shaking. At this time, the shaking of the L-shaped fixing block 12 will drive the whole protective cover 1 to shake; Furthermore, as shown in Figure 7 , when the protective cover 1 shakes, at this time, due to its own gravity, the protective cover 1 will drive the pressing plate 31 to start rotating. Since the pressing plate 31 is symmetrically rotationally connected to the bottom of the protective cover 1 and the working principles are the same, only one group of the reference numerals shown in Figure 7 will be described. At this time, under the action of the protective cover 1 pushing down the pressing plate 31, the pressing plate 31 will push the T-shaped block 32 to slide on the upper surface of the L-shaped fixing block 12; Furthermore, since the T-shaped block 32 symmetrically slides on the outer surface of the fixed shaft 33, and the buffer spring 34 is sleeved on the middle part of the fixed shaft 33 and fixed to the T-shaped block 32 at the same time, at this time, the mutual extrusion of the T-shaped blocks 32 will drive the buffer spring 34 to start being compressed. At this time, the extrusion column 38 fixedly connected to the bottom of the T-shaped block 32 and the inclined groove 37 will drive the L-shaped clamping plate 36 to squeeze the rubber plate 39. Since the rubber plate 39 is made of rubber soft material, the extrusion will slow down the overall shaking of the protective cover 1; When the carbon emission collector 11 collects carbon emissions from passing vehicles, especially when the impact force generated by the vehicle or strong wind weather causes the support rod to shake, at this time, the L-shaped fixing block 12 will shake synchronously under the transmission of the support rod's shaking. Due to the key damping effect of the extrusion of the L-shaped clamping plate 36 and the rubber plate 39 components in the present invention, when the carbon emission collector 11 is driven to shake by the L-shaped fixing block 12, at this time, through the mutual extrusion of the inclined groove 37 opened on the L-shaped clamping plate 36 by the extrusion column 38 in the T-shaped block 32, the design of the present invention can reduce the shaking influence of the support rod on the carbon emission collector 11 of the collection device, thus greatly improving the stability of the carbon emission collector 11 device during the collection process. Even in the face of external environmental interference and changes, the present invention can ensure that the collected carbon emission data is more accurate and reliable; Furthermore, compared with the above patent which is driven by a motor, with the setting of the present invention, by using the impact effect of the gas, it can automatically drive the cleaning swing rod 23 to clean the surface of the second filter plate 25. Through the design of the present invention, not only the stable operation of the device in bad weather is ensured, but also when encountering wind force, this mechanism can drive the V-shaped baffle 21 to be automatically cleaned. It can not only effectively avoid the problems of accidental power failure and blockage of the second filter plate 25 caused by special weather, but also ensure that the device can continuously and accurately collect data. Compared with the design in the above patent, the present invention not only greatly reduces the cost investment, but also significantly reduces the energy consumption. The design of the present invention can clean the surface of the second filter plate 25 in real time only by relying on simple mechanical transmission, effectively prevent blockage, and improve the overall performance and reliability of the device.
