Description

Technical Field

[0001] This utility model relates to the field of exhaust gas measurement technology, specifically to a particulate matter measuring device for an exhaust gas sampling platform. Background Technology

[0002] In environmental pollution control, one aspect is the monitoring and management of the air environment. Industrial pollution and vehicle exhaust pollution are two major contributors to air quality. Detecting and analyzing vehicle exhaust is fundamental to targeted pollution prevention and control. Currently, vehicle exhaust testing typically requires the use of an exhaust sampling platform.

[0003] Regarding the aforementioned technologies, the applicant argues that when operating an exhaust gas sampling platform, the vehicle to be tested must first be moved onto the platform before a particle spectrometer is used to analyze particulate matter in the exhaust gas. However, during the testing process, due to significant differences in the position and height of exhaust pipes across different vehicle models, the particle spectrometer is highly susceptible to collision with the vehicle's exhaust pipe. When the particle spectrometer is damaged, it needs to be removed for repair. Currently, particle spectrometers are typically securely fixed to the exhaust gas sampling platform using embedded clips, requiring specialized pry tools for disassembly, which can easily damage surrounding components. This complex procedure prolongs the repair time and reduces the device's repair efficiency. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] Example 1

[0029] Please see Figures 1 to 5This embodiment provides a technical solution: a particulate matter measuring device for an exhaust gas sampling platform, including an exhaust gas sampling platform body 1, an electric slide rail 2, and an installation mechanism 3. The electric slide rail 2 is fixedly connected to one end of the top of the exhaust gas sampling platform body 1. A sliding block 6 is provided above the electric slide rail 2, and the sliding block 6 can be moved by the operation of the electric slide rail 2. The installation mechanism 3 is located at the top of the sliding block 6. The installation mechanism 3 includes a fixing seat 301 fixedly connected to the top of the sliding block 6. The fixing seat 301 can provide load-bearing capacity. The fixing seat 301 is connected to the sliding block 6 by fixing bolts. An installation plate 302 is provided through the interior of the fixing seat 301. The fixing seat 301 has an installation groove, which is T-shaped. The mounting plate 302 is inserted into the mounting slot, which facilitates the positioning of the mounting plate 302. A particle spectrometer body 4 is located at the center of the top of the mounting plate 302. The particle spectrometer body 4 can be used to sample and detect exhaust gases from a car exhaust pipe, thereby analyzing particulate matter in the exhaust gas. The particle spectrometer body 4 is connected to the mounting plate 302 by fixing bolts. A handle 5 is fixedly connected to the center of the top of the particle spectrometer body 4, and an anti-slip sleeve is fixedly connected to the outside of the handle 5, facilitating the movement of the particle spectrometer body 4 by operators. Movable rods 305 are provided through both ends of the fixed base 301. The movable rods 305 provide load-bearing capacity, and a limiting spring 306 is sleeved on the outside of the movable rod 305. The limiting spring 306... Figure 5 As shown, under no external force, it is in the maximum tension state. The end of the movable rod 305 near the mounting plate 302 is fixedly connected to the snap-fit ​​block 307. The snap-fit ​​block 307 is connected to the movable rod 305 by a fixing bolt. The movable rod 305 drives the snap-fit ​​block 307 to move laterally.

[0030] The effect achieved by the entire embodiment is as follows: by pulling the limiting sleeve 303 upward, the limiting sleeve 303 can be moved out of the outside of the movable rod 305. Then, pulling the movable rod 305 can drive the locking block 307 to move, and the locking block 307 can be moved out of the mounting plate 302. Then, the mounting plate 302 can be moved out of the fixed seat 301, thereby facilitating the removal of the particle spectrometer body 4 for maintenance and effectively improving the maintenance speed of the device.

[0031] Example 2

[0032] Limiting blocks 304 are fixedly connected to the top of both ends of the fixed base 301. The limiting blocks 304 can provide load-bearing capacity. The limiting blocks 304 are connected to the fixed base 301 by fixing bolts. The limiting blocks 304 have a movable groove 309 inside. A moving rod 308 is slidably arranged inside the movable groove 309. The moving rod 308 moves up and down inside the movable groove 309. A limiting sleeve 303 is fixedly connected to the outside of the moving rod 308. The limiting sleeve 303 is arranged outside the movable rod 305.

[0033] The effect achieved by the entire second embodiment is as follows: by pulling the moving rod 308 to the bottom of the movable groove 309, the limiting sleeve 303 can be moved to the outside of the movable rod 305, which can facilitate the limiting of the movable rod 305 and improve the stability of the particle spectrometer body 4 during operation.

[0034] Example 3

[0035] Both ends of the mounting plate 302 have limit holes, which match the locking block 307, as shown in the attached figure. Figure 4 As shown, when the limiting spring 306 is not under force, the limiting spring 306 can push the snap-fit ​​block 307 into the limiting hole inside the mounting plate 302 by its own elastic force; there are two sets of snap-fit ​​blocks 307, which are symmetrically distributed about the internal center point of the fixing seat 301, which can improve the fixing effect of the snap-fit ​​blocks 307 on the mounting plate 302.

[0036] The effect achieved by the entire embodiment 3 is that the elasticity of the limiting spring 306 can push the snap block 307 into the limiting groove inside the mounting plate 302, which can facilitate the fixing of the mounting plate 302.

[0037] Working principle: First, start the device and move the car to the exhaust gas sampling platform 1. Then, through the operation of the electric slide rail 2, the sliding block 6 can be moved to move the particle spectrometer 4 to the car exhaust pipe. The particle spectrometer 4 can be used to sample and detect the exhaust gas emitted from the car exhaust pipe, thereby analyzing and detecting the particulate matter in the exhaust gas.

[0038] Secondly, when the particle spectrometer body 4 is damaged, by pulling the limiting sleeve 303 upward, the limiting sleeve 303 can be moved out of the outside of the movable rod 305. Then, by pulling the movable rod 305, the locking block 307 can be moved, and the locking block 307 can be moved out of the limiting groove inside the mounting plate 302. Then, the mounting plate 302 can be moved out of the fixed base 301, which makes it convenient to remove the particle spectrometer body 4 for maintenance and effectively improves the maintenance speed of the device.

[0039] Finally, after the particle spectrometer body 4 is repaired, the mounting plate 302 can be inserted into the fixed base 301. Then, the elasticity of the limiting spring 306 can be used to push the snap block 307 into the limiting groove inside the mounting plate 302. Then, the moving rod 308 can be pulled to the bottom of the movable groove 309, and the limiting sleeve 303 can be moved to the outside of the movable rod 305. This makes it easier to limit the movable rod 305 and improves the stability of the particle spectrometer body 4 during operation.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
