Description

Technical Field

[0001] This utility model relates to the field of automobile exhaust gas collection, and more specifically, to an automobile exhaust gas collection device. Background Technology

[0002] Vehicle exhaust is one of the main sources of urban air pollution, containing carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). x Vehicle exhaust emissions contain pollutants such as particulate matter (PM). By collecting vehicle exhaust data, the concentration and total amount of these pollutants can be analyzed, thereby assessing their impact on regional air quality and providing data support for developing air quality improvement measures. Various countries and regions have established strict vehicle exhaust emission standards. Collecting exhaust emissions and analyzing their composition and content can determine whether a vehicle's actual emissions meet the corresponding standards. Vehicles that do not meet the standards are required to undergo repair or be scrapped to reduce the operation of high-polluting vehicles and mitigate the environmental harm caused by exhaust emissions.

[0003] In existing technologies, collecting exhaust gases from vehicles typically requires two people: one to start the engine and the other to hold the collection hose. Holding the hose continuously is inconvenient and poses a safety hazard when positioned behind the vehicle. Therefore, we propose an improvement: a vehicle exhaust gas collection device. Utility Model Content

[0004] The purpose of this utility model is to address the existing problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] Vehicle exhaust gas collection devices are used to improve the above-mentioned problems.

[0007] The present invention is as follows:

[0008] The system includes a main frame with rubber plugs inserted into it. Columns are fixedly installed at both ends of the main frame, and mounting plates are fixedly installed at the bottom of each column. A moving mechanism is located at the bottom of each mounting plate. A threaded rod is threadedly connected to the main frame, and a driving mechanism is located at the bottom of the threaded rod. A sliding rod is slidably connected inside each column. A base is rotatably engaged at the top of both the sliding rod and the threaded rod. A slot is provided at the top of the base, and a plug is inserted into the slot. A protrusion is fixedly connected to the top of the plug, and a collection tube is fixedly installed on the top of the protrusion. A gas collection bag is located at the left end of the collection tube, and a locking mechanism is provided on the base.

[0009] As a preferred technical solution of this utility model, the left end of the collection tube is integrally formed with a threaded connecting tube.

[0010] As a preferred technical solution of this utility model, a threaded connecting sleeve is fixedly connected to the gas collection bag, and the threaded connecting sleeve is matched with the threaded connecting pipe.

[0011] As a preferred technical solution of this utility model, the moving mechanism includes a brake caster fixedly installed at the bottom of the mounting plate.

[0012] As a preferred technical solution of this utility model, the driving mechanism includes a handle fixedly installed at the bottom of the threaded rod.

[0013] As a preferred technical solution of this utility model, the locking mechanism includes a locking bolt disposed on the base.

[0014] As a preferred technical solution of this utility model, the insert block is provided with a locking groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. By turning the handle, the threaded rod rotates, which in turn moves the base at its top. The base moves, which in turn moves the protrusion, which in turn moves the collection tube. The collection tube is then aligned with the vehicle's exhaust pipe. The device is then pushed so that the collection tube fits over the exhaust pipe. The universal wheel is then braked, and the threaded connecting sleeve on the gas collection bag is connected to the threaded connecting tube at the left end of the collection tube. This allows for exhaust gas collection. The operation can be completed by just one person, and the sampling tube does not need to be held by the operator during the collection process. This solves the problem that existing technologies usually require two people to operate, one to start the engine in the car and the other to hold the gas collection tube. Holding the tube is not only inconvenient but also poses a safety hazard when standing behind the car.

[0018] 2. The removable collection tube allows for easy removal and cleaning. Attached Figure Description

[0030] Example:

[0031] like Figure 1-4As shown, this embodiment proposes a vehicle exhaust gas collection device, including a main frame 1. A rubber plug 19 is inserted into the main frame 1 to seal the gas collection bag 11. Columns 2 are fixedly installed at both ends of the main frame 1, and mounting plates 3 are fixedly installed at the bottom of the columns 2. A moving mechanism is provided at the bottom of the mounting plates 3 to facilitate the movement of the device. A threaded rod 4 is threadedly connected to the main frame 1, and a driving mechanism is provided at the bottom of the threaded rod 4 to drive the threaded rod 4 to rotate. A sliding rod 6 is slidably connected inside the columns 2, and slides within the columns 2. Both the threaded rod 4 and the top of the base 7 are rotatably engaged with the base 7. The top of the base 7 has a slot 14, and a plug 15 is inserted into the slot 14. A protrusion 8 is fixedly connected to the top of the plug 15, and a collection tube 9 is fixedly installed on the top of the protrusion 8. When the collection tube 9 is lifted, the collection tube 9 drives the protrusion 8, and the protrusion 8 drives the plug 15, so that the plug 15 is moved out of the slot 14 at the top of the base 7, and the collection tube 9 can be removed for cleaning. A gas collection bag 11 is provided at the left end of the collection tube 9 to collect gas. The base 7 is provided with a locking mechanism.

[0032] A threaded connecting pipe 10 is integrally formed at the left end of the collecting pipe 9, and a threaded connecting sleeve 12 is fixedly connected to the gas collecting bag 11. The threaded connecting sleeve 12 on the gas collecting bag 11 is connected to the threaded connecting pipe 10 at the left end of the collecting pipe 9, and the threaded connecting sleeve 12 matches the threaded connecting pipe 10.

[0033] The moving mechanism includes brake casters 18 fixedly mounted on the bottom of the mounting plate 3, which makes the device easy to move.

[0034] The drive mechanism includes a handle 13 fixedly installed at the bottom of the threaded rod 4, which drives the threaded rod 4 to rotate.

[0035] The locking mechanism includes a locking bolt 16 mounted on the base 7 and a locking groove 17 provided on the insert block 15. The locking bolt 16 is removed so that it disengages from the locking groove 17 on the insert block 15.

[0036] Specifically, when using this vehicle exhaust gas collection device, first place the device on the ground and adjust the height of the collection pipe 9 according to the height of the vehicle: turn the handle 13, the turn of the handle 13 drives the threaded rod 4 to turn, and at the same time the threaded rod 4 drives the base 7 at its top to move. The movement of the base 7 will drive the protrusion 8, and the protrusion 8 will drive the collection pipe 9 to move (at the same time, the other two protrusions 8 at the bottom of the collection pipe 9 will drive the base 7 at the top of the slide rod 6, and the base 7 will drive the slide rod 6 to slide in the column 2), so that the collection pipe 9 is moved to correspond with the vehicle exhaust gas emission pipe. Then push the device so that the collection pipe 9 fits over the vehicle exhaust gas emission pipe. Then brake the universal wheel 18. Then connect the threaded connecting sleeve 12 on the gas collection bag 11 to the threaded connecting pipe 10 at the left end of the collection pipe 9. Then the worker can enter the vehicle, start the car engine, and let the exhaust gas be discharged into the gas collection bag 11. Finally, remove the gas collection bag 11 and use the rubber stopper 19 to plug the threaded connecting sleeve 12 on the gas collection bag 11.

[0037] When the collection tube 9 needs to be cleaned, first remove the locking bolt 16 so that the locking bolt 16 is disengaged from the locking groove 17 on the insert block 15. Then lift the collection tube 9. The collection tube 9 drives the protrusion 8, and the protrusion 8 drives the insert block 15 so that the insert block 15 is moved out of the slot 14 at the top of the base 7. Then the collection tube 9 can be removed.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
