Description

Technical Field

[0001] This utility model belongs to the field of automotive exhaust emission detection technology and relates to a portable integrated pumping and refueling device. Background Technology

[0002] For vehicle emissions testing, compliant fuel must be used according to testing requirements. Therefore, before the vehicle is tested, the original fuel in the fuel tank must be drained and replaced with the fuel used for testing.

[0003] The existing method for testing fuel changes usually involves manually draining the crude oil from the fuel tank and then injecting the testing fuel into the tank. This method is slow in terms of fuel extraction and refueling efficiency, and because the equipment is large, it is inconvenient to move around. It is also limited by the different testing vehicles and sites, resulting in poor performance.

[0004] To address the aforementioned technical issues, we propose a portable integrated pumping and refueling device. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the method of testing fuel replacement usually involves manually extracting the crude oil from the fuel tank and then injecting the testing fuel into the tank. When changing fuel, the efficiency of oil extraction and refueling is slow, and because the equipment is large in size, it is inconvenient to move back and forth. It is also limited by the different testing vehicles and sites, resulting in poor performance.

[0006] This utility model discloses a portable pumping and refueling integrated device, comprising a mobile trolley. A pneumatic diaphragm pump is mounted on the top of the trolley. An air pressure regulating valve is fixedly connected to the air inlet on the circumferential side of the pneumatic diaphragm pump. A pressure gauge is fixedly connected to the front end of the air pressure regulating valve. An oil outlet pipe is fixedly connected to the top of the pneumatic diaphragm pump. An oil metering gauge is fixedly connected to the end of the oil outlet pipe away from the pneumatic diaphragm pump. An oil outlet is fixedly connected to the end of the oil metering gauge away from the oil outlet pipe. An oil delivery pipe is fixedly connected to the bottom of the pneumatic diaphragm pump. A T-junction is fixedly connected to the end of the oil delivery pipe away from the pneumatic diaphragm pump. A large oil inlet pipe is fixedly connected to the end of the T-junction away from the pneumatic diaphragm pump. A small oil inlet pipe is fixedly connected to one side of the T-junction. Switching regulating valves are mounted on the tops of both the large and small oil inlet pipes. Oil inlets are fixedly connected to the ends of both the large and small oil inlet pipes away from the T-junction.

[0007] The bottom end of the oil pipeline is fixedly connected to multiple bases, the inner side of the base is fixedly connected to a sliding frame, the outer side of the sliding frame is slidably connected to a first adjusting seat, and the bottom end of the first adjusting seat is rotatably connected to a lifting bracket.

[0008] A bidirectional screw is rotatably connected to the center of the bottom inner side of the mobile trolley, and sliding columns are fixedly connected to both ends of the bottom inner side of the mobile trolley. Multiple second adjustment seats are slidably connected to the circumferential side of the sliding columns, and the bottom end of the lifting bracket is rotatably connected to the corresponding second adjustment seat.

[0009] A first transmission gear is fixedly connected to one side of the bidirectional screw. A connecting frame is fixedly connected to the inner side of the moving trolley at a position corresponding to the first transmission gear. A servo motor is fixedly connected to the side of the connecting frame near the bidirectional screw. A second transmission gear is provided on the side of the connecting frame away from the bidirectional screw. The output end of the servo motor is fixedly connected to the second transmission gear. The first transmission gear and the second transmission gear are meshed together.

[0010] Both sides of the bidirectional screw are threaded with movable seats, and both ends of the movable seats are fixedly connected with fixed frames. The ends of the fixed frames away from the bidirectional screw are fixedly connected to the corresponding second adjusting seats.

[0011] A closed cover is rotatably connected to one side of the top of the mobile trolley, and multiple wheels are provided at the bottom of the mobile trolley.

[0012] An oil tank is fixedly connected to one end of the mobile trolley, and a storage rack is slidably connected to one end of the mobile trolley at a position corresponding to the closed cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: through the structural design of the pneumatic diaphragm pump and the three-way pipe, the pneumatic diaphragm pump eliminates the risk of safety accidents caused by electric sparks from the electric oil pump. The three-way pipe, in conjunction with the switching regulating valve, forms a switchable pipeline with one large and one small inlet. The large inlet pipe is used in the early stage of oil extraction and refueling to improve efficiency, while the small inlet pipe is used in the later stage to remove the remaining oil, ensuring that there is no original vehicle fuel in the fuel tank that would affect the test results. The amount of oil extracted is accurately recorded to ensure the integrity of the test data and avoid the problem of insufficient refueling affecting the efficiency of the test or excessive refueling causing resource waste.

[0014] The design of the mobile trolley and the closed cover allows the pneumatic diaphragm pump to be easily stored in the mobile trolley for protection when not in use. This reduces the impact of dust and other impurities entering the exposed external pipeline on the pump's subsequent oil pumping efficiency. Furthermore, the mobile trolley provides protection for the pneumatic diaphragm pump during movement, preventing damage from bumps and knocks and extending the lifespan of the device.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example 1

[0023] like Figures 1-4As shown, a portable integrated pumping and refueling device includes a mobile cart 1. A pneumatic diaphragm pump 2 is mounted on the top of the mobile cart 1. The pneumatic diaphragm pump 2 eliminates the risk of safety accidents caused by electric sparks from an electric pump. An intake pressure regulating valve 3 is fixedly connected to the air inlet on the circumferential side of the pneumatic diaphragm pump 2. A pressure gauge 4 is fixedly connected to the front end of the intake pressure regulating valve 3, facilitating the control of fuel flow rate through the intake pressure regulating valve 3 and the pressure gauge 4. This allows for the selection of a suitable fuel flow rate based on the characteristics of the vehicle's refueling port, preventing fuel spraying from affecting refueling volume statistics, the detection environment, and causing resource waste. A fuel outlet pipe 5 is fixedly connected to the top of the pneumatic diaphragm pump 2. A fuel metering gauge 6 is fixedly connected to the end of the fuel outlet pipe 5 away from the pneumatic diaphragm pump 2. The oil injection volume is accurately recorded by the oil metering gauge 6 to ensure the integrity of the test data and avoid the impact of insufficient injection volume on the test efficiency or the waste of resources caused by excessive injection volume. The oil metering gauge 6 is fixedly connected to an oil outlet at the end away from the oil outlet pipe 5. The bottom end of the pneumatic diaphragm pump 2 is fixedly connected to an oil delivery pipe 7. The end of the oil delivery pipe 7 away from the pneumatic diaphragm pump 2 is fixedly connected to a three-way pipe 8. The end of the three-way pipe 8 away from the pneumatic diaphragm pump 2 is fixedly connected to a large oil inlet pipe 9. The side of the three-way pipe 8 is fixedly connected to a small oil inlet pipe 10. The top ends of both the large oil inlet pipe 9 and the small oil inlet pipe 10 are equipped with switching regulating valves 11. The ends of both the large oil inlet pipe 9 and the small oil inlet pipe 10 away from the three-way pipe 8 are fixedly connected to oil inlets.

[0024] During operation, after the required pipelines on the pneumatic diaphragm pump 2 are installed, the pneumatic diaphragm pump 2 is started, and the fuel in the vehicle to be tested is extracted through the hose installed on the large oil inlet pipe 9. After most of the fuel is extracted, the remaining fuel in the vehicle to be tested is extracted through the hose on the small oil inlet pipe 10. During the extraction and refueling process, the supply pressure of the pneumatic diaphragm pump 2 is adjusted by the intake pressure regulating valve 3 and the pressure gauge 4, thereby controlling the fuel flow rate during the extraction and refueling process.

[0025] Example 2

[0026] like Figure 1 and Figure 4 As shown, in order to maintain the stability of the pneumatic diaphragm pump 2 during use, a plurality of bases 12 are fixedly connected to the bottom end of the oil delivery pipe 7. A sliding frame 13 is fixedly connected to the inner side of the base 12, and a first adjusting seat 14 is slidably connected to the outer side of the sliding frame 13. A lifting bracket 15 is rotatably connected to the bottom end of the first adjusting seat 14.

[0027] To facilitate the safe storage of the pneumatic diaphragm pump 2 inside the mobile trolley 1, a bidirectional screw 16 is rotatably connected to the center of the bottom inner side of the mobile trolley 1. Both ends of the bottom inner side of the mobile trolley 1 are fixedly connected to sliding columns 17. Multiple second adjustment seats 18 are slidably connected to the circumferential side of the sliding columns 17. The bottom end of the lifting bracket 15 is rotatably connected to the corresponding second adjustment seat 18, thereby facilitating the adjustment of the distance between the base 12 and the sliding column 17 through the lifting bracket 15.

[0028] To drive the bidirectional screw 16 to rotate, a first transmission gear 19 is fixedly connected to one side of the bidirectional screw 16. A connecting frame 20 is fixedly connected to the inner side of the moving trolley 1 at a position corresponding to the first transmission gear 19. A servo motor 21 is fixedly connected to the side of the connecting frame 20 closest to the bidirectional screw 16, and a second transmission gear 22 is provided on the side of the connecting frame 20 furthest from the bidirectional screw 16. To facilitate the rotation of the second transmission gear 22, the output end of the servo motor 21 is fixedly connected to the second transmission gear 22. To facilitate the rotation of the first transmission gear 19, the first transmission gear 19 is meshed with the second transmission gear 22.

[0029] To facilitate the sliding of the second adjusting seat 18 on the sliding column 17, both sides of the bidirectional screw 16 are threaded with a movable seat 23, and both ends of the movable seat 23 are fixedly connected with a fixing frame 24. The end of the fixing frame 24 away from the bidirectional screw 16 is fixedly connected to the corresponding second adjusting seat 18.

[0030] During operation, when the pneumatic diaphragm pump 2 needs to be stored in the mobile trolley 1, the servo motor 21 is started, and the output end of the servo motor 21 drives the second transmission gear 22 to rotate. The second transmission gear 22 then drives the first transmission gear 19 and the bidirectional screw 16 to rotate. When the bidirectional screw 16 rotates, it causes the two moving seats 23 on it to move away from each other. The moving seats 23, through the fixed frame 24, drive the second adjusting seat 18 on the sliding column 17 to move away from each other. This causes the lifting bracket 15 on the second adjusting seat 18 to drive the pneumatic diaphragm pump 2 downward through its rotating shaft, thereby allowing the pneumatic diaphragm pump 2 to be stored in the mobile trolley 1 for easy storage and protection.

[0031] Example 3

[0032] like Figure 1 and Figure 3 As shown, in order to further protect the pneumatic diaphragm pump 2 after it has been stored, a closed cover 25 is rotatably connected to one side of the top of the mobile trolley 1. In order to facilitate the movement of the device, multiple casters 26 are provided at the bottom of the mobile trolley 1.

[0033] During operation, the device is moved by the moving wheels 26, allowing it to quickly reach the working position and making it unrestricted by space.

[0034] Example 4

[0035] like Figure 1 and Figure 3 As shown, in order to facilitate the storage of the extracted oil, an oil tank 27 is fixedly connected to one end of the mobile trolley 1. In order to facilitate the storage of the pipes used, a storage rack 28 is slidably connected to one end of the mobile trolley 1 at a position corresponding to the closed cover 25.
