Description

Technical Field

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

[0002] In Chinese patent publication number CN221506413U, a carbon emission collection device is disclosed, comprising a housing, a detection mechanism disposed within the housing, a suction mechanism connected to the front end of the detection mechanism, and a filter plate disposed at the front end of the suction mechanism, a cleaning mechanism connected to the front end of the filter plate, and the cleaning mechanism connected to the front end of the housing. The housing is connected to the upper end of a base via a positioning plate, a mounting plate connected to the rear end of the base, and the device body is mounted on a roadside via the mounting plate. The detection mechanism within the housing draws in external air via the suction mechanism, and the filter plate, provided at the front end of the housing, prevents foreign matter from entering and is cleaned by a cleaning mechanism connected to the outside of the filter plate, thereby preventing clogging of the filter pores of the filter plate and facilitating absorption by the suction mechanism.

[0003] However, the above patent still has the following defects when used in practice:

[0004] 1. In the above patent, although the function of cleaning the surface of the filter plate has been realized, its cleaning mechanism is driven by a motor, which not only requires continuous reliance on power supply during use, but also under special windy and severe weather conditions, such as power supply abnormality or interruption, the cleaning mechanism may not be able to clean the surface of the filter plate in a timely and effective manner. Since the wind will blow dust and impurities into the air, if the surface of the filter plate cannot be cleaned in time, it will easily cause the filter plate to become blocked due to failure to clean it in time, thereby affecting its normal operation.

[0005] 2. In addition, when carbon emissions are detected on the road, when a vehicle passes quickly under the collector, the vehicle's weight and speed will generate large kinetic energy and impact force. 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 pole above the road, the shaking may cause the sensor inside the collector to shift or deviate, because the sensor needs to maintain a stable position and state to accurately measure carbon emissions data, which in turn affects the accuracy of data collection.

[0006] Therefore, an urban road traffic carbon emission verification data collection device is proposed to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a data collection device for urban road traffic carbon emissions verification to solve the problem in the existing technology that the collector is easily affected by vibration interference during congestion and vehicle carbon emissions collection and detection under special circumstances.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: a data collection device for verifying carbon emissions in urban road traffic, comprising a protective cover, a wind monitor mounted on the upper end of the protective cover, a carbon emission collector mounted in the middle of the protective cover, an L-shaped fixing block disposed at the bottom of the protective cover, an automatic dust removal and flow blocking mechanism, and a multifunctional protective mechanism, wherein the automatic dust removal and flow blocking mechanism is disposed on the carbon emission collector, and the multifunctional protective mechanism is disposed at the bottom of the protective cover;

[0009] The automatic dust removal and flow blocking mechanism is used for collecting air and preventing dust in the carbon emission collector;

[0010] The multifunctional protection mechanism is used for shock absorption and anti-shake of the protection cover.

[0011] Preferably, the automatic dust removal baffle mechanism includes a V-shaped baffle, an oblique extrusion groove is provided in the middle of the upper end of the V-shaped baffle, and guide grooves are rotatably connected on both sides of the upper end of the V-shaped baffle, and the guide groove is fixedly connected to the carbon emission collector at one end away from the V-shaped baffle.

[0012] Preferably, a cleaning rocker arm is rotatably connected in the angled extrusion groove, a cleaning plate is provided at one end of the cleaning rocker arm away from the angled extrusion groove, and a second filter plate is provided above the cleaning plate, and the second filter plate is fixedly connected to the gas collection port of the carbon emission collector.

[0013] Preferably, a first filter plate is fixedly connected to the bottom of the carbon emission collector, and the filter holes provided in the first filter plate are larger than the filter holes provided in the second filter plate.

[0014] Preferably, the multifunctional protective mechanism includes a pressing plate, one end of which is rotatably connected to the bottom of the protective cover, and the other end of the pressing plate 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 fixed block.

[0015] Preferably, the multifunctional protective mechanism also includes a fixed shaft, both ends of the fixed shaft are fixedly connected to the upper surface of the L-shaped fixed block, the T-shaped block is symmetrically slidably connected to the outer surface of the fixed shaft, and a buffer spring is sleeved on the outer surface of the middle part of the fixed shaft, and both ends of the buffer spring are fixedly connected to the T-shaped block.

[0016] Preferably, return springs are evenly arranged on the upper surface of the L-shaped fixed block and near the bottom of the T-shaped block, one end of the return spring is fixedly connected to the L-shaped fixed block, and the other end of the return 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 fixed block.

[0017] Preferably, the upper surface of the L-shaped splint is symmetrically provided with inclined grooves, an extrusion column is slidably connected in the inclined groove, the end of the extrusion column away from the inclined groove is fixedly connected to the bottom of the T-shaped block, and the outer surface of the L-shaped fixed block close to the L-shaped splint is fixedly connected to a rubber plate, and the rubber plate is made of soft rubber material.

[0018] Compared with the existing technology, the urban road traffic carbon emission verification data collection device provided by the present invention has the following beneficial effects:

[0019] 1. The present invention adopts the V-shaped spoiler. When a vehicle passes quickly, the weight and speed of the vehicle generate large kinetic energy and impact force to drive the V-shaped spoiler to rotate in the guide groove. At this time, due to the action of the oblique extrusion groove at the beginning of the V-shaped spoiler, when the V-shaped spoiler rotates, it drives the cleaning swing rod connected to the oblique extrusion groove to swing in the middle of the guide groove. When the cleaning swing rod swings, the cleaning plate of the cleaning swing rod can clean fine dust on the outer surface of the second filter plate, thereby preventing the second filter plate from being blocked.

[0020] 2. Compared with the above-mentioned patents which are driven by motors, the present invention is set up so that the impact of gas can be used to automatically drive the cleaning rocker to clean the surface of the second filter plate. The design of the present invention not only ensures the stable operation of the equipment in bad weather, but also can drive the V-shaped baffle to automatically clean through this mechanism even if it encounters wind. It can not only effectively avoid the problem of accidental power outages and blockage of the second filter plate caused by special weather, but also ensure that the equipment can continuously and accurately collect data. Compared with the design in the above-mentioned patents, the present invention not only greatly reduces the cost investment, but also significantly reduces energy consumption. The design of the present invention relies solely on simple mechanical transmission to clean the surface of the second filter plate in real time, effectively prevent blockage, and improve the overall performance and reliability of the equipment.

[0021] 3. The V-shaped spoiler is set in a V shape, so when a vehicle passes quickly, the vertical rotation of the V-shaped spoiler can block the airflow of the vehicle in the guide groove. The airflow blocking effect of the V-shaped spoiler when the vehicle is driving will slow down the flow of the airflow under the obstruction of the V-shaped spoiler, which allows the carbon emission particles in the airflow more time to contact the carbon emission collection instrument detection device above, thereby improving the accuracy of the measurement of carbon emissions in the air. At the same time, the design of the present invention does not require an additional power source, which not only increases the accuracy of the detection, but also greatly reduces energy consumption, reflecting the green and environmentally friendly design concept.

[0022] 4. Through the setting of the multi-functional protective mechanism, when the carbon emission collector is collecting carbon emissions from a passing vehicle, especially when the impact force generated by the vehicle or strong winds cause the support rod to shake, the L-shaped fixing block will shake under the transmission of the support rod. The extrusion of the L-shaped plywood and the rubber plate component in the present invention plays a key damping role. When the carbon emission collector is driven to shake by the L-shaped fixing block, the extrusion column in the T-shaped block squeezes the inclined groove of the L-shaped plywood. The design of the present invention can reduce the impact of the support rod on the shaking of the carbon emission collector, thereby greatly improving the stability of the carbon emission collector 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.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0036] For example, please refer to Figures 1 to 7 As shown:

[0037] To solve the problems mentioned in the technical solution, the embodiment of the present application provides an urban road traffic carbon emission verification data collection device, including a protective cover 1, a wind monitor 13 is installed on the upper end of the protective cover 1, a carbon emission collection instrument 11 is installed in the middle of the protective cover 1, an L-shaped fixing block 12 is provided at the bottom of the protective cover 1, and the device also includes an automatic dust removal and flow blocking mechanism 2 and a multifunctional protective mechanism 3, the automatic dust removal and flow blocking mechanism 2 is provided on the carbon emission collection instrument 11, and the multifunctional protective mechanism 3 is provided at the bottom of the protective cover 1;

[0038] The automatic dust removal and flow blocking mechanism 2 is used for collecting air and preventing dust from the carbon emission collector 11;

[0039] The multifunctional protection mechanism 3 is used to reduce shock and prevent vibration of the protective cover 1;

[0040] The automatic dust removal blocking mechanism 2 includes a V-shaped baffle 21, an oblique extrusion groove 22 is opened in the middle of the upper end of the V-shaped baffle 21, and guide grooves 26 are rotatably connected on both sides of the upper end of the V-shaped baffle 21. The end of the guide groove 26 away from the V-shaped baffle 21 is fixedly connected to the carbon emission collector 11;

[0041] A cleaning swing rod 23 is rotatably connected to the angled extrusion groove 22. A cleaning plate is provided at one end of the cleaning swing rod 23 away from the angled extrusion groove 22, and a second filter plate 25 is provided above the cleaning plate. The second filter plate 25 is fixedly connected to the gas collection port of the carbon emission collector 11.

[0042] A first filter plate 24 is fixedly connected to the bottom of the carbon emission collector 11. The filter holes formed in the first filter plate 24 are larger than the filter holes formed in the second filter plate 25.

[0043] Among them: the protective cover 1 adopts a curved cone setting for waterproof and windproof settings, wherein the oblique extrusion groove 22 at one end of the V-shaped spoiler 21 is inclined, and the two ends of the V-shaped spoiler 21 are rotatably connected in the guide groove 26. The rotation of the V-shaped spoiler 21 in the guide groove 26 can drive the cleaning swing rod 23 to swing on the surface of the second filter plate 25.

[0044] Compared with the above patent, the implementation of this embodiment not only greatly reduces the cost investment, but also significantly reduces the energy consumption. The design of the present invention relies solely on simple mechanical transmission to clean the surface of the second filter plate 25 in real time, effectively prevent clogging, and improve the overall performance and reliability of the equipment.

[0045] For further examples, please refer to Figures 1 to 7 As shown:

[0046] The multifunctional protective mechanism 3 includes a pressing plate 31, one end of which 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, and the bottom of the T-shaped block 32 is slidably connected to the upper surface of the L-shaped fixing block 12;

[0047] The multifunctional protection mechanism 3 further includes a fixed shaft 33, the ends of which are fixedly connected to the upper surface of the L-shaped fixed block 12, and the T-shaped block 32 is 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 portion of the fixed shaft 33, and the ends of the buffer spring 34 are fixedly connected to the T-shaped block 32;

[0048] Restoration springs 35 are evenly arranged on the upper surface of the L-shaped fixing block 12 and near the bottom of the T-shaped block 32. One end of the restoring spring 35 is fixedly connected to the L-shaped fixing block 12, and the other end of the restoring 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.

[0049] The upper surface of the L-shaped clamping plate 36 is symmetrically provided with inclined grooves 37, and an extrusion column 38 is slidably connected to the inclined groove 37. The end of the extrusion column 38 away from the inclined groove 37 is fixedly connected to the bottom of the T-shaped block 32. The outer surface of the L-shaped fixing block 12 near the L-shaped clamping plate 36 is fixedly connected to a rubber plate 39. The rubber plate 39 is made of soft rubber material.

[0050] Among them: the multifunctional protection mechanism 3 is symmetrically arranged on both sides of the bottom of the carbon emission collector 11, and the carbon emission collector 11 is provided with a backup power supply. When the wind monitor 13 is monitoring severe weather and strong winds, the wind monitor 13 can cut off the external power supply of the carbon emission collector 11 in time, and at the same time start the internal backup power supply of the carbon emission collector 11, avoiding equipment failure or data loss caused by external power supply problems.

[0051] Compared with the above-mentioned patent, the implementation of this embodiment can reduce the impact of the support rod on the shaking of the carbon emission collector 11 of the collection equipment, thereby greatly improving the stability of the carbon emission collector 11 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.

[0052] Everything in the above example works as follows:

[0053] In the initial state: the cleaning rocker arm 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.

[0054] The following is the working process of the automatic dust removal and flow blocking mechanism 2 for collecting air and preventing dust in the carbon emission collector 11:

[0055] When a device passes by a vehicle, due to the vehicle's mass and speed, it will generate interaction forces with the road surface. 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 firmly fixed, it will be easily affected by this force and shake.

[0056] On the other hand, when a car is driving, airflow disturbance will be generated, especially when driving at high speed. The car will form a low-pressure area, and the surrounding airflow will quickly fill this area, forming 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.

[0057] 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.

[0058] 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 3As shown, when the airflow blows from the left side of the V-shaped spoiler 21, it drives the V-shaped spoiler 21 to start rotating in the counterclockwise direction. At this time, since the upper ends of the V-shaped spoiler 21 are rotatably connected to the guide groove 26, the weight of the vehicle itself and the driving speed 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 action of the oblique extrusion groove 22 provided on the V-shaped spoiler 21, when the V-shaped spoiler 21 rotates, it drives the cleaning swing rod 23 connected to the oblique extrusion groove 22 to swing in the middle of the guide groove 26. When the V-shaped spoiler 21 rotates, it drives the oblique extrusion groove 22 to squeeze the surface of the cleaning swing rod 23. At the same time, because the cleaning swing rod 23 slides in the guide groove 26 away from the outer surface of the oblique extrusion groove 22, the guiding effect of the guide groove 26 causes the V-shaped spoiler 21 to rotate in the guide groove 26, and at the same time drives the cleaning swing rod 23 to swing in the middle 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, thereby preventing the second filter plate 25 from being blocked.

[0059] By setting the V-shaped spoiler 21 in a V-shape, when a vehicle passes quickly, the vertical rotation of the V-shaped spoiler 21 can block the airflow passing through the vehicle in the guide groove 26. The flow speed of the airflow will be slowed down by the obstruction of the V-shaped spoiler 21, which allows the carbon emission particles in the airflow to have more sufficient time to contact the detection device of the carbon emission collector 11 above, thereby improving the accuracy of the measurement of carbon emissions in the air. At the same time, the design of the present invention does not require an additional power source, which not only increases the accuracy of the detection, but also greatly reduces energy consumption, reflecting the green and environmentally friendly design concept.

[0060] Please refer to the above working process Figures 1 to 7 .

[0061] The following is the working process of the multifunctional protection mechanism 3 for shock absorption and anti-vibration of the protection cover 1:

[0062] As mentioned above, when carbon emissions are set at different high-speed detection ports, due to the high speed of vehicles, when the collector is installed on a bracket above the road surface, due to the relatively long extension distance of the bracket, when the vehicle passes under the bracket at high speed, a strong dynamic effect will be generated. This effect is specifically manifested in the interaction force between the vehicle and the road surface, as well as the airflow disturbance generated by the vehicle when driving;

[0063] When a vehicle passes by quickly, its enormous kinetic energy and speed instantly generate a strong impact on the road surface. This impact not only acts on the road surface itself, but is also transmitted through the road surface and the bracket to the carbon emission collection device above. Due to the long extension distance of the bracket, it cannot effectively absorb and disperse this impact, so the collection device will be significantly affected by shaking.

[0064] At this time, shaking the bracket will drive Figure 1 The L-shaped fixing block 12 shown starts to shake, and the shaking of the L-shaped fixing block 12 drives the entire protective cover 1 to shake;

[0065] Further Figure 7 As shown, when the protective cover 1 shakes, the protective cover 1 will drive the pressing plate 31 to start rotating due to its own gravity. Since the pressing plate 31 rotates symmetrically and connects to the bottom of the protective cover 1, the working principle is the same, so only the following Figure 7 The reference numerals are shown as a group for description. At this time, the protective cover 1 pushes the pressing plate 31 downward, and the pressing plate 31 pushes the T-shaped block 32 to slide on the upper surface of the L-shaped fixing block 12;

[0066] Furthermore, since the T-shaped block 32 slides symmetrically 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 on the T-shaped block 32, the mutual squeezing of the T-shaped blocks 32 will drive the buffer spring 34 to begin to be compressed. At this time, the squeezing column 38 and the inclined groove 37 fixedly connected at the bottom of the T-shaped block 32 will squeeze each other, which will drive the L-shaped clamping plate 36 to squeeze the rubber plate 39. Since the rubber plate 39 is made of soft rubber material, the squeezing will reduce the shaking of the protective cover 1 as a whole.

[0067] When the carbon emission collector 11 is collecting carbon emissions from a passing vehicle, especially when the impact force generated by the vehicle or strong winds cause the support rod to shake, the shaking transmission of the support rod will cause the L-shaped fixing block 12 to shake synchronously. Since the extrusion of the L-shaped clamping plate 36 and the rubber plate 39 in the present invention plays a key damping role, when the carbon emission collector 11 is driven to shake by the L-shaped fixing block 12, the extrusion column 38 in the T-shaped block 32 squeezes the inclined groove 37 of the L-shaped clamping plate 36. The design of the present invention can reduce the impact of the support rod on the shaking of the carbon emission collector 11, thereby greatly improving the stability of the carbon emission collector 11 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.

[0068] Furthermore, compared with the above-mentioned patents which are driven by a motor, the present invention is set up so that the impact of gas can be used to automatically drive the cleaning rocker 23 to clean the surface of the second filter plate 25. The design of the present invention not only ensures the stable operation of the equipment in bad weather, but also can drive the V-shaped spoiler 21 to be automatically cleaned through this mechanism even if it encounters wind. It can not only effectively avoid the problem of accidental power outages and blockage of the second filter plate 25 caused by special weather, but also ensure that the equipment can continuously and accurately collect data. Compared with the design in the above-mentioned patents, the present invention not only greatly reduces the cost investment, but also significantly reduces energy consumption. The design of the present invention relies solely on simple mechanical transmission to clean the surface of the second filter plate 25 in real time, effectively prevent blockage, and improve the overall performance and reliability of the equipment.
