Description

Technical Field

[0001] This utility model relates to the field of motor vehicle exhaust emission detection technology, specifically a motor vehicle detection device with exhaust gas recovery function. Background Technology

[0002] Motor vehicle exhaust emission testing devices are specialized equipment used to accurately measure the concentration of pollutants in motor vehicle exhaust and determine whether emissions meet standards. The core of the device consists of three major systems: a detection module, a control module, and a data module. It is widely used in testing stations, environmental supervision, and other scenarios.

[0003] Existing detection devices typically have a recovery structure to recover carbon dioxide from exhaust gas. To achieve efficient recovery, a mesh plate is usually installed in the recovery box to ensure uniform carbon dioxide flow. However, in actual use, the carbon dioxide usually concentrates in a certain area and requires a long period of movement to be evenly separated by the mesh plate, which reduces the absorption rate of carbon dioxide. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0027] Please see Figure 1-4 As shown, this utility model is a motor vehicle testing device with exhaust gas recovery function, comprising:

[0028] The detection and recycling assembly includes a sampling tube 101, a sampling pump 102, a receiving tube 103, a detector 104, a receiving cylinder 105, a blower 106, a recycling box 107, and a box cover 108.

[0029] The uniform diffusion assembly includes an adsorbent plate 201, a mesh plate 202, an L-shaped rod 203, a motor 204, and a stirring plate 205. The adsorbent plate 201 and the mesh plate 202 are movably connected in the recovery box 107. One end of the L-shaped rod 203 is fixedly connected to the inner wall of the recovery box 107, and the other end of the L-shaped rod 203 is fixedly connected to the motor 204. The output end of the motor 204 is connected to the stirring plate 205. There are a total of three stirring plates 205, which are fixedly connected to each other.

[0030] Sampling tube 101 is inserted into the exhaust pipe for sampling. Sampling pump 102 extracts the exhaust gas. Receiving tube 103 is used to transfer the gas.

[0036] The slot 1011 provides a guarantee for the easy disassembly and assembly of the cover 108.

[0037] Working principle: The sampling tube 101 is inserted into the exhaust pipe of the motor vehicle, the sampling pump 102 is started, and the extracted exhaust gas is transmitted to the detector 104 through the receiving tube 103. The detector 104 uses infrared sensing technology to measure the concentration of various pollutants in the exhaust gas and complete the detection step. The fan 106 is started, and the detected exhaust gas is transmitted from one side of the detector 104 to the inside of the recovery box 107 through two receiving cylinders 105. The motor 204 is started, and the motor drives three mutually fixed stirring plates 205 to rotate, which quickly disperses the exhaust gas entering the recovery box 107. The dispersed exhaust gas passes through the mesh of the mesh plate 202 and diffuses evenly to the adsorbent plate 201. The amine-functionalized mesoporous silica adsorbent particles in the adsorbent plate 201 adsorb the evenly diffused exhaust gas (mainly carbon dioxide), completing the recovery process.

[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The easy-to-assemble and disassemble component includes a limiting groove 301, a T-shaped limiting rod 302, a rectangular plate 303, and a spring 304. The limiting groove 301 is opened through the cover 108, and one end of the T-shaped limiting rod 302 is movably connected in the limiting groove 301. The rectangular plate 303 is fixedly connected to the side of the recycling box 107, and the spring 304 is movably connected between the T-shaped limiting rod 302 and the rectangular plate 303. The easy-to-assemble and disassemble component also includes a guide groove 305, a guide rod 306, and a pull rod 307. The guide groove 305 is opened through the rectangular plate 303, and the spring 304 is movably sleeved on the outside of the guide rod 306.

The pull rod 307 is fixedly connected to the side of the T-shaped limiting rod 302.

[0040] The rectangular plate 303 ensures the opening of the guide groove 305, the guide groove 305 ensures the movable connection of the guide rod 306, the guide rod 306 ensures the movable connection of the spring 304, and the spring 304 can securely insert the T-shaped limiting rod 302 into the limiting groove 301, thereby achieving a firm engagement of the cover 108 and preventing the cover 108 from falling off during movement. Furthermore, pulling down the pull rod 307 can quickly disengage the T-shaped limiting rod 302 from the limiting groove 301, thereby enabling the quick disassembly of the cover 108 and improving the overall ease of assembly and disassembly.

[0041] Working principle: After the box cover 108 is inserted into the slot 1011 of the recycling box 107, the spring 304 on the rectangular plate 303 generates elastic force, pushing the T-shaped limiting rod 302 upward, so that one end of it is inserted into the limiting groove 301 of the box cover, realizing the secure locking of the box cover and preventing it from falling off during movement. When disassembling the box cover 108, pull the pull rod 307 downward, and the T-shaped limiting rod 302 drives the guide rod 306 to move downward along the guide groove 305 of the rectangular plate 303. The spring 304 is compressed. When the T-shaped limiting rod is completely disengaged from the limiting groove 301, the box cover can be pulled out along the slot 1011 to complete the quick disassembly.
