Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring and control technology, and in particular to a device for capturing and detecting particulate matter in motor vehicle exhaust. Background Technology

[0002] A motor vehicle exhaust particulate matter capture and detection device is a device used to reduce particulate matter emissions from motor vehicle exhaust and monitor related data. It consists of capture devices such as particulate traps and electrostatic traps, and detectors such as corona ionization, laser scattering, and spectral analysis. It can capture particulate matter in exhaust gas to reduce pollution, and at the same time detect information such as the concentration, particle size distribution, and composition of particulate matter, providing data support for exhaust emission control and environmental supervision.

[0003] The vehicle exhaust particulate matter capture and detection device draws exhaust gas into a detection pipeline using an air pump. A particulate matter cutting unit filters charged particles in the exhaust gas according to their size, allowing target particles of a specific size to enter the charge detection unit. Simultaneously, a discharge unit ionizes the air in the charging chamber, charging the particles so that the charge detection unit can determine their concentration. Meanwhile, the filter layer in the purification component intercepts particles, the activated carbon mesh layer adsorbs harmful substances, the particulate matter collection chamber collects the filtered particles, sensors monitor filter blockage in real time, and the intelligent analysis module uses an ultra-lightweight edge computing model and an intelligent exhaust pollutant identification algorithm to analyze and process the detection data in real time, ultimately achieving efficient capture and accurate detection of vehicle exhaust particulate matter.

[0004] In existing technologies, when the collection unit accumulates a large amount of particulate matter, it is difficult to disassemble quickly, requiring more time to disassemble the complex structure, which leads to extended maintenance cycles, increased equipment downtime, and affects the continuity of testing. In the face of adjustment requirements for different vehicle models or exhaust emission conditions, it is difficult to quickly disassemble and replace the adaptable parts, making it difficult for the device to flexibly adapt to diverse testing scenarios and limiting its application scope. Therefore, a motor vehicle exhaust particulate matter collection and detection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vehicle exhaust particulate matter capture and detection device, which aims to improve the problems of low maintenance and cleaning efficiency, high difficulty in troubleshooting, and high cost of component replacement in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A motor vehicle exhaust particulate matter capture and detection device includes a sampling tube. Cylinders are fixedly connected to both sides of the sampling tube. Sliding rings are fixedly connected to the driving ends of the two cylinders. Transmission plates are fixedly connected to the outer walls of the two sliding rings. Hollow columns are fixedly connected to both sides of the two sampling tubes. Multiple limiting plates are fixedly connected to the inner walls of the hollow columns. Multiple springs are fixedly connected to the inner walls of the hollow columns. Fixed blocks are fixedly connected to the other ends of the multiple springs. A shock-absorbing component for vibration reduction is installed on the outer wall of the telescopic sampling tube.

[0008] As a further description of the above technical solution:

[0009] The shock absorption assembly includes two U-shaped plates. The interior of each U-shaped plate is fixedly connected to the outer wall of the sampling tube. The top of each U-shaped plate is fixedly connected to a fixing plate. The top of the fixing plate is fixedly connected to a connecting plate. The inner wall of the connecting plate is rotatably connected to two connecting rods. The other end of each connecting rod is rotatably connected to a slider. The top of the fixing plate is fixedly connected to a spring. The top of the fixing plate is fixedly connected to a support rod. The other end of each spring is fixedly connected to a fixing plate.

[0010] As a further description of the above technical solution:

[0011] The hollow column has holes on its outer wall and an air outlet pipe is slidably connected to its inner wall.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the sliding ring is slidably connected to the outer wall of the sampling tube, and the outer wall of the transmission plate is slidably connected to the inner wall of the fixed block;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the transmission plate is slidably connected to the inner wall of the limiting plate, and the outer wall of the fixing block is slidably connected to the inner wall of the limiting plate.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the second spring is sleeved on the outer wall of the support rod, and the inner wall of the second fixing plate is provided with a sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the starting cylinder drives the sliding ring to move, causing the transmission plate to press against the fixed block. The fixed block slides within the hollow column under the constraint of the positioning plate, and the spring is compressed and buffered, enabling quick disassembly of the exhaust pipe. It is compatible with exhaust pipes of different car models and can automatically adapt to various types of automotive exhaust pipes. When it is necessary to adjust the parts to adapt to a new car model, the quick disassembly function can quickly complete the operation, greatly improving the flexibility and compatibility of the equipment. The shell can be disassembled in sections to quickly access the internal adsorption mesh for cleaning and maintenance, greatly shortening the maintenance time and improving work efficiency.

[0024] 2. In this utility model, when the sampling tube is vibrated, the U-shaped plate transmits the vibration to the fixed plate one. The connecting rod rotatably connected to the connecting plate drives the slider to move, and the spring two is compressed to absorb the vibration energy. At the same time, the support rod provides support and guidance for the fixed plate two. The various components work together to effectively buffer the vibration. The motor vehicle exhaust particulate matter capture and detection device is equipped with a shock-absorbing component, which can effectively improve the stability and service life of the equipment. During vehicle operation, bumps and vibrations are inevitable. Without a shock-absorbing component, the precision sensors, circuit boards, and other components inside the detection device are prone to loosening and poor contact due to continuous vibration, affecting the accuracy of the detection data and the normal operation of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a motor vehicle exhaust particulate matter capture and detection device, including a sampling tube 1. The sampling tube 1 serves as a support for subsequent components. Cylinders 2 are fixedly connected to both sides of the sampling tube 1, providing mounting support for the cylinders 2 and preventing shaking or displacement during operation. Sliding rings 3 are fixedly connected to the drive ends of the two cylinders 2. The cylinders 2 drive the sliding rings 3 to slide along the outer wall of the sampling tube 1, converting the linear motion of the cylinders 2 into the translational motion of the sliding rings 3. Transmission plates 4 are fixedly connected to the outer walls of the two sliding rings 3, causing the sliding rings 3 to move synchronously with the transmission plates 4. The transmission plates 4 transmit the motion of the sliding rings 3 to subsequent components. Hollow columns 5 are fixedly connected to both sides of the two sampling tubes 1, providing a fixed foundation for the hollow columns 5 and providing protection and movement space for subsequent components.

[0033] Multiple limiting plates 6 are fixedly connected to the inner wall of the hollow column 5. The limiting plates 6 are fixed to the inner wall of the hollow column 5 to provide a sliding trajectory for subsequent components. Multiple springs 7 are fixedly connected to the inner wall of the hollow column 5. The hollow column 5 supports the springs 7. The springs 7 provide a reset and buffer function for subsequent components. The other end of the multiple springs 7 is fixedly connected to a fixing block 8. The springs 7 provide elastic support and reset force for the fixing block 8, so that the fixing block 8 can return to its initial position after being subjected to force. The outer wall of the telescopic sampling tube 1 is equipped with a shock-absorbing component for vibration reduction. The shock-absorbing component reduces the impact of vibration of the vehicle running on the sampling tube 1.

[0034] Reference Figures 2 to 4The vibration damping assembly includes two U-shaped plates 9. The U-shaped plates 9 are used to fix the sampling tube 1 and continue to transmit the vibration. The interior of both U-shaped plates 9 is fixedly connected to the outer wall of the sampling tube 1. The U-shaped plates 9 are fixed to the outer wall of the sampling tube 1, receiving and transmitting the vibration of the sampling tube 1 to the vibration damping assembly. The top of both U-shaped plates 9 is fixedly connected to a fixing plate 10. The U-shaped plates 9 support the fixing plate 10 and transmit the vibration to the fixing plate 10, triggering the linkage of the vibration damping assembly. The top of the fixing plate 10 is fixedly connected to a connecting plate 11. The fixing plate 10 supports the connecting plate 11, so that the connecting plate 11 can drive the movement of the subsequent components when vibrating. The inner wall of the connecting plate 11 is rotatably connected to two connecting rods 12. The connecting plate 11 provides a rotation fulcrum for the connecting rods 12. The connecting rods 12 disperse the vibration by changing their angle under the drive of the connecting plate 11.

[0035] The other ends of both connecting rods 12 are rotatably connected to sliders 13. The connecting rods 12 drive the sliders 13 to slide in the groove, converting vibration energy into the kinetic energy of the sliders 13. The top of each fixed plate 10 is fixedly connected to a spring 14. The fixed plate 10 fixes one end of the spring 14. When the spring 14 is subjected to force, it compresses and absorbs vibration energy, playing a buffering role. The top of each fixed plate 10 is fixedly connected to a support rod 15. The fixed plate 10 supports the support rod 15. The support rod 15 provides guidance for the fixed plate 16, ensuring its smooth movement. The other ends of multiple springs 14 are fixedly connected to the fixed plate 16. The springs 14 are connected to the fixed plate 16. Through elastic deformation, they buffer vibration and protect the sampling tube 1 from severe vibration.

[0036] Reference Figures 2 to 4 Hollow column 5 has holes on its outer wall, which provide installation space for subsequent components and allow for quick installation. An air outlet pipe 17 is slidably connected to the inner wall of hollow column 5, providing a sliding track for the air outlet pipe 17 for installation and removal. The inner wall of sliding ring 3 is slidably connected to the outer wall of sampling tube 1, allowing it to slide smoothly along the tube. The outer wall of transmission plate 4 is slidably connected to the inner wall of fixed block 8, transmitting the movement of sliding ring 3 to fixed block 8 and dragging subsequent components. The outer wall of transmission plate 4 is slidably connected to the inner wall of limiting plate 6, guiding and limiting the movement of transmission plate 4, ensuring it moves along a predetermined trajectory and preventing deviation that could affect device operation.

[0037] The outer wall of the fixed block 8 is slidably connected to the inner wall of the limiting plate 6. The outer wall of the fixed block 8 slides on the inner wall of the limiting plate 6, which restricts the range of motion of the fixed block 8 and ensures that the fixed block 8 slides stably within the hollow column 5. The inner wall of the second spring 14 is sleeved on the outer wall of the support rod 15. The support rod 15 provides support and guidance for the second spring 14. The inner wall of the second fixed plate 16 has a sliding groove, which provides a sliding track for the slider 13, ensuring that the slider 13 slides along a fixed path during vibration transmission. The outer wall of the slider 13 is slidably connected to the inner wall of the second fixed plate 16. The wall slides in the groove on the inner wall of the second fixed plate 16, converting the vibration transmitted by the connecting rod 12 into its own linear motion. The outer wall of the support rod 15 is slidably connected to the inner wall of the second fixed plate 16. The outer wall of the support rod 15 slides on the inner wall of the second fixed plate 16, providing support and guidance for the second fixed plate 16. The top end of the sampling tube 1 contacts the bottom end of the first fixed plate 10. The first fixed plate 10 receives the vibration transmitted by the sampling tube 1 and transmits it to other components of the shock absorption assembly, thereby achieving shock absorption protection for the sampling tube 1. The inner wall of the limiting plate 6 is provided with a groove, and the limiting plate 6 provides sliding guidance for the fixed block 8 and the transmission plate 4.

[0038] Working principle: When it is necessary to fix or disassemble the air outlet pipe 17, the cylinders 2 on the left and right sides of the sampling tube 1 are activated. The driving end of the cylinder 2 pushes the sliding ring 3 to slide on the outer wall of the sampling tube 1. The sliding ring 3 drives the transmission plate 4 to move synchronously. The transmission plate 4 squeezes the fixing block 8, causing the fixing block 8 to slide on the inner wall of the limiting plate 6. The limiting plate 6 on the inner wall of the hollow column 5 restricts the movement trajectory of the fixing block 8. At the same time, the spring 7 is compressed to generate elastic buffering force. Throughout the process, the cylinder 2 provides power to make the sliding ring 3 and the transmission plate 4 move. The spring 7 and the limiting plate 6 cooperate to achieve buffering and limiting, thereby fixing and disassembling the air outlet pipe 17.

[0039] When the vibration generated by the motor vehicle is transmitted to the sampling tube 1, the U-shaped plate 9 fixed to the outer wall of the sampling tube 1 receives the vibration and transmits it to the fixed plate 10 connected to the top. The fixed plate 10 drives the connecting plate 11 at the top to be stressed. The two connecting rods 12 connected to the inner wall of the connecting plate 11 change their angle accordingly. The slider 13 connected to the other end of the connecting rod 12 slides in the groove. The vibration is dispersed through the lever principle. At the same time, the spring 14 fixed to the top of the fixed plate 10 is compressed and undergoes elastic deformation, absorbing and buffering the vibration energy. The fixed plate 16 provides stable support and guidance for the support rod 15, ensuring that the support rod 15 moves smoothly under the action of the spring 14 and preventing it from deviating or shaking. Through the transmission of the U-shaped plate 9, the linkage between the connecting rod 12 and the slider 13, the buffering of the spring 14, and the support of the support rod 15, the shock absorption component effectively weakens the impact of vibration on the sampling tube 1, ensuring the accuracy and stability of the exhaust gas particulate matter capture and detection work.
