Description

Technical Field

[0001] This invention relates to the field of oil pipe cleaning technology, and more specifically to a high-pressure oil pipe inner bore cleaning device. Background Technology

[0002] High-pressure oil pipes are a component of high-pressure oil circuits. They are required to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. High-pressure oil pipes for vehicles are mainly found in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines, and can withstand the oil pressure required during engine operation.

[0003] The working pressure of conventional diesel engine high-pressure fuel lines is generally between 800 bar and 1600 bar. With the advent of common rails, the working pressure of diesel engine high-pressure fuel lines and common rails has been continuously increasing, currently reaching a maximum of 2500 bar. Diesel engines also have increasingly higher requirements for the cleanliness of the fuel system. If the inner wall of the high-pressure fuel line or common rail is not clean, it will lead to clogging of the fuel injection holes, poor atomization, and even needle valve sticking, affecting fuel injection accuracy and combustion efficiency. Long-term operation will also accelerate the wear of fuel injectors, reduce fuel injection pressure, and further deteriorate combustion. In addition, impurities entering the fuel pump will accelerate the wear of precision components such as gears and plungers inside the pump, resulting in insufficient pump oil pressure and unstable fuel supply. In severe cases, it may cause premature damage to the fuel pump.

[0004] Conventional cleaning methods mainly involve oil flushing, where diesel fuel is repeatedly flowed through the high-pressure oil pipe or common rail to achieve a cleaning effect. However, since diesel fuel flows axially and the pressure is generally low, it cannot achieve a high degree of cleanliness in the inner cavity. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-pressure oil pipe inner bore cleaning device to solve the problems mentioned in the background section.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A high-pressure oil pipe internal cleaning device includes a cleaning box with a transparent plate fixedly installed on one side; and a cleaning assembly disposed on one side of the cleaning box for cleaning the internal bore of the high-pressure oil pipe. The cleaning assembly includes an installation tube fixedly installed on one side of the cleaning box, passing through one side of the cleaning box and extending into the interior of the cleaning box. The outer circular wall of the installation tube is threaded, and a spray pipe is threadedly connected to the outer circular wall of the installation tube. The inner circular wall of the spray pipe is threaded, and a nozzle is fixedly sleeved on the inner circular wall of the spray pipe. One end of the nozzle has several nozzles. A drip-proof shell is fixedly installed on one side of the cleaning box. An adsorption assembly for restricting one end of the high-pressure oil pipe is disposed inside the drip-proof shell. A displacement assembly for moving the high-pressure oil pipe is disposed on one side of the drip-proof shell.

[0008] By adopting the above technical solution, a cleaning tank is installed, and diesel fuel is injected into the tank. Then, a high-pressure oil pipe is fitted over the nozzle, allowing the diesel fuel inside the cleaning tank to be injected into the nozzle through the installation pipe. The diesel fuel is then sprayed out through the nozzle and several nozzles. At this time, the diesel fuel is directly sprayed into the interior of the high-pressure oil pipe. Because the nozzles diffuse outward in a scattering pattern and the opening angle of the nozzles is aimed at the inner wall of the high-pressure oil pipe, the diesel fuel is completely sprayed onto the inner wall of the high-pressure oil pipe, which facilitates the washing away of impurities in the inner wall and gaps of the high-pressure oil pipe, ultimately achieving a high degree of cleanliness.

[0009] Preferably, the adsorption assembly includes: two snap-fit ​​rings, both of which are disposed inside the anti-drip shell and spaced apart; the inner circular wall of each snap-fit ​​ring has a plurality of negative pressure holes; a mounting bracket is fixedly installed on the bottom surface of the anti-drip shell; a negative pressure pump is fixedly installed on the top surface of the mounting bracket; a dispersion tube is fixedly installed on the bottom surface of the anti-drip shell; an air suction tube is fixedly installed on the outside of the dispersion tube and extends into the interior of the dispersion tube; the air suction tube is fixedly connected to the air intake port of the negative pressure pump; negative pressure tubes are fixedly installed at both ends of the dispersion tube and extend into the interior of the dispersion tube; and the other end of the negative pressure tube is fixedly installed to the snap-fit ​​ring.

[0010] By adopting the above technical solution, when cleaning the inner hole of the high-pressure oil pipe through the set negative pressure hole, the high-pressure oil pipe is first moved between the two clamping rings, and then the high-pressure oil pipe is sleeved on the outside of the nozzle, so that the two clamping rings are close to the outer wall of the initial end of the high-pressure oil pipe. At the same time, by using the negative pressure pump, the negative pressure pump will generate negative pressure suction after starting. Then the negative pressure pump will transmit the suction to the two negative pressure pipes through the suction pipe and the dispersion pipe respectively, and then through the clamping rings and the negative pressure hole to the surface of the high-pressure oil pipe, thereby facilitating the adsorption and clamping of the high-pressure oil pipe.

[0011] Preferably, the displacement component includes: a stepper motor, which is fixedly installed on one side of the drip-proof shell. Movable holes are respectively opened on both sides of the drip-proof shell. A lead screw is movably sleeved inside the right-side movable hole. The drive shaft of the stepper motor passes through one side of the drip-proof shell and is fixedly installed with the lead screw. A slide rail is fixedly installed inside the left-side movable hole. A sliding table is movably sleeved inside the movable hole. A threaded hole is opened on one side of the right-side sliding table, and the threaded hole is threadedly connected to the lead screw. The left-side sliding table is movably sleeved with the slide rail.

[0012] By adopting the above technical solution, and through the sliding table, when the high-pressure oil pipe is restricted by the two clamping rings through negative pressure, the stepper motor drives the lead screw to rotate. The rotation of the lead screw causes the sliding table to move the clamping rings, the negative pressure pipe and the high-pressure oil pipe at a constant speed, which can move the high-pressure oil pipe closer to the cleaning box, thereby facilitating the nozzle and spray head to penetrate into the interior of the high-pressure oil pipe.

[0013] Preferably, a fixed post is fixedly installed on one side of the sliding table, a connecting rod is fixedly installed on the outside of the snap ring, the connecting rod is movably sleeved with the fixed post, a fixed ring is fixedly sleeved on the outer circular wall of the fixed post, a movable groove is formed on the outer circular wall of the fixed ring, a movable ring is movably sleeved on the outer circular wall of the fixed ring, a limit ring is fixedly sleeved on the inner circular wall of the movable ring, the limit ring is movably sleeved with the movable groove, a thread is formed on the inner circular wall of the movable ring, a thread is formed on the outer circular wall of the connecting rod, and the movable ring is threadedly connected to the connecting rod.

[0014] By adopting the above technical solution, and through the set movable ring, according to different high-pressure oil pipe sizes, the operator can rotate the movable ring and move the connecting rod. Then the connecting rod will move outward through the inside of the fixed column, allowing the clamping ring to approach the surface of the high-pressure oil pipe, thus facilitating the clamping of high-pressure oil pipes of different sizes.

[0015] Preferably, an oil tank is provided on one side of the cleaning tank, and a high-pressure oil pump is provided between the oil tank and the cleaning tank. A fixed pipe is fixedly sleeved inside the oil outlet of the high-pressure oil pump. The fixed pipe is fixedly installed with the cleaning tank and extends into the interior of the cleaning tank. An oil suction pipe is fixedly sleeved inside the oil inlet of the high-pressure oil pump. The oil suction pipe is fixedly installed with the oil tank and extends into the interior of the oil tank.

[0016] By adopting the above technical solution, through the set oil tank, the staff injects diesel into the oil tank to clean the inside of the high-pressure oil pipe. After the high-pressure oil pump is running, it will draw out the diesel from the oil tank through the oil extraction pipe and inject it into the inside of the cleaning tank through the fixed pipe, thus facilitating the oil filling of the cleaning tank and the inside of the spray pipe.

[0017] Preferably, L-shaped brackets are fixedly installed on both sides of the oil tank, and a drive motor is fixedly installed on one side of each L-shaped bracket. Sliding holes are provided on both sides of the oil tank, and limit grooves are respectively formed on the top and bottom surfaces of the sliding holes. A rotating column is movably connected to one side of each L-shaped bracket. The drive shaft of the drive motor is fixedly installed to the rotating column. A first gear is fixedly sleeved on the outer circular wall of the rotating column. Two second gears are meshed on the outer circular wall of the first gear. A movable rod and a connecting column are fixedly installed on one side of each of the two second gears. A movable bracket is provided on one side of the first gear, and a limit groove is formed on one side of the movable bracket. There are two rotating holes. The movable frame is fixedly installed with the rotating column. The two rotating holes are respectively movably connected to the movable rod and the connecting column. A pushing column is movably connected to the outer circular wall of the connecting column. A connecting arm is fixedly installed on one side of the pushing column. A moving block is slidably connected inside the sliding hole. Limit blocks are fixedly installed on the top and bottom surfaces of the moving block. The limit blocks are slidably connected to the limit groove. An installation column is fixedly installed on one side of the moving block. A moving arm is movably connected to the outer circular wall of the installation column. A cleaning column is fixedly installed on one side of the moving arm. Several scrapers are fixedly installed on the outer circular wall of the cleaning column.

[0018] By adopting the above technical solution, the first gear, when diesel fuel is injected into the tank, positions the scraper at the surface of the diesel fuel. The drive motor's drive shaft rotates, causing the rotating column and the first gear to rotate. The first gear then meshes with and drives two second gears to rotate. These two second gears rotate around the outside of the first gear, causing the movable rod and connecting column to rotate the movable frame and pushing column. Since the movable frame is triangular with one corner connected to the connecting column and pushing column, its rotation changes the position of the pushing column. When the connecting column rotates closer to the upper position, the movable frame pushes the pushing column, causing the connecting arm, moving block, cleaning column, and scraper to move linearly. The rotation of the movable frame then causes the pushing column to move the moving block and moving arm linearly back and forth, allowing the scraper to scrape the surface of the diesel fuel, thus facilitating the scraping and cleaning of the diesel fuel surface after it enters the tank.

[0019] Preferably, an inclined platform is fixedly installed inside the oil tank, a servo motor is fixedly installed on the bottom surface of the inclined platform, a rotating column is fixedly installed on the top surface of the servo motor drive shaft, the rotating column passes through the bottom surface of the inclined platform, an agitator is provided on the top surface of the inclined platform, the agitator is fixedly installed with the rotating column, and a plurality of agitator columns are fixedly installed on the top surface of the agitator.

[0020] By adopting the above technical solution, and through the agitation column, when diesel fuel enters the interior of the fuel tank, the servo motor drives the rotating column, agitator, and agitation column to rotate, thereby facilitating the agitation of the diesel fuel and preventing it from becoming viscous after being left to stand for a long time.

[0021] Preferably, an oil inlet pipe is fixedly installed on one side of the oil tank and extends into the interior of the oil tank, and a feed hopper is fixedly installed on the top surface of the oil inlet pipe.

[0022] By adopting the above technical solution, diesel fuel can be injected into the inside of the fuel tank.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] 1. The cleaning tank is filled with diesel fuel as the cleaning medium. During cleaning, the high-pressure oil pipe is fitted over the nozzle. The diesel fuel in the cleaning tank is transported to the nozzle through the installation pipe and finally sprayed out at high speed through the nozzle set at the front end and several nozzles evenly distributed in a scattering pattern. This forms the cleaning flow generation and injection unit. After being driven by high pressure, the diesel fuel is directly sprayed radially and at multiple angles from the nozzles with precise design angles onto the inner wall of the high-pressure oil pipe, forming a high-pressure vortex that covers the entire area. This flushing method can powerfully wash away metal debris, welding slag, gum and other impurities attached to the inner wall and micro gaps. The cleaning effect is far superior to that of traditional axial flow cleaning.

[0025] 2. Before cleaning, the high-pressure oil pipe is placed between two clamping rings and fitted onto the nozzle through the negative pressure hole and matching clamping mechanism. After starting the negative pressure pump, the suction force is transmitted to the negative pressure hole on the clamping ring through the suction pipe, dispersion pipe, and negative pressure pipe, realizing non-mechanical contact fixation of the workpiece. The negative pressure suction force gently and firmly adsorbs the high-pressure oil pipe onto the two clamping rings. This fixing method avoids the surface scratches or deformation of the pipe that may be caused by traditional clamps. It is especially suitable for high-pressure oil pipes with high surface precision requirements and can adapt to a certain range of pipe diameter changes.

[0026] 3. After the high-pressure oil pipe is fixed, the lead screw is driven by the stepper motor to rotate, which drives the sliding table and the entire clamping mechanism installed on it, including the snap ring, negative pressure pipe and high-pressure oil pipe, to move at a constant speed. This controls the precise relative movement between the high-pressure oil pipe and the nozzle, so that the stationary nozzle and nozzle can gradually penetrate into the interior of the high-pressure oil pipe, or make the high-pressure oil pipe sweep across the spray area at a constant speed. This combination of axial feed motion and radial high-pressure spray ensures that the entire inner wall of the oil pipe can be flushed by the cleaning fluid without dead angles, achieving high cleanliness throughout the process.

[0027] 4. By rotating the movable ring, the connecting rod can be driven to move within the fixed column, thereby adjusting the relative distance between the two locking rings and realizing the adaptive adjustment of the aperture of the clamping mechanism. This allows a single device to be compatible with various specifications of high-pressure oil pipes or common rail pipes, significantly improving the versatility and practicality of the equipment and reducing the cost and time of replacing special clamps for different products.

[0028] 5. The system includes a scraper inside the fuel tank and a linkage mechanism consisting of a drive motor, a first gear, a second gear, and a movable frame. The motor drives the first gear to rotate, and through gear meshing and linkage transmission, this is ultimately converted into a linear reciprocating motion of the scraper on the diesel fuel surface. This automatically cleans the scum on the fuel tank surface and periodically removes impurities, foam, or oxide layers that may float on the diesel fuel surface due to cleaning backflow. This prevents these contaminants from being pumped back into the cleaning system and causing secondary pollution, thus maintaining the purity of the cleaning medium.

[0029] 6. The agitator and agitator column inside the oil tank are driven by a servo motor. After the servo motor starts, it drives the agitator to rotate, preventing the diesel fuel from settling and becoming locally viscous. It gently agitates the diesel fuel in the tank, keeping its composition uniform and fluid. This avoids the sedimentation of heavy components or local aging after long-term standing, ensuring the stability of the physicochemical properties of the cleaning oil and thus guaranteeing the consistency of the cleaning effect each time.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A high-pressure oil pipe internal cleaning device includes a cleaning box 1. A transparent plate 2 is fixedly installed on one side of the cleaning box 1. A cleaning assembly is provided on one side of the cleaning box 1 for cleaning the internal bore of the high-pressure oil pipe. The cleaning assembly includes an installation pipe 3, which is fixedly installed on one side of the cleaning box 1. The installation pipe 3 passes through one side of the cleaning box 1 and extends into the interior of the cleaning box 1. The outer circular wall of the installation pipe 3 is threaded, and a spray pipe 4 is threaded to the outer circular wall of the installation pipe 3. A nozzle 5 is fixedly sleeved on the inner circular wall of the spray pipe 4. One end of the nozzle 5 has several nozzles 6. The cleaning box 1 is fixedly installed on one side. With a drip-proof shell 7, an oil inlet pipe 54 is fixedly installed on one side of the oil tank 30 and extends into the interior of the oil tank 30. A feed hopper 55 is fixedly installed on the top surface of the oil inlet pipe 54. This device is a cleaning equipment specifically designed for the inner walls of high-pressure oil pipes and common rail pipes. Its core innovation lies in changing the traditional axial flow cleaning method and adopting radial high-pressure flushing technology. Through an adjustable nozzle structure, negative pressure fixing system, automatic feeding mechanism and oil circulation purification system, it achieves efficient and high-cleanliness cleaning of the inner walls of workpieces of different specifications. It effectively solves the problem of insufficient cleanliness caused by low pressure and single flow direction in traditional methods, and ensures the reliability of the fuel system from the source.

[0043] By filling the cleaning tank 1 with diesel fuel, and then attaching a high-pressure oil pipe to the outside of the nozzle 4, the diesel fuel inside the cleaning tank 1 is injected into the nozzle 4 through the installation pipe 3. The diesel fuel is then sprayed out through the nozzle 5 and several nozzles 6. At this time, the diesel fuel is directly sprayed into the inside of the high-pressure oil pipe. Since the nozzles 6 diffuse outward in a scattering manner and the opening angle of the nozzles 6 is aimed at the inner wall of the high-pressure oil pipe, the diesel fuel is completely sprayed onto the inner wall of the high-pressure oil pipe, which facilitates the washing away of impurities in the inner wall and gaps of the high-pressure oil pipe, ultimately achieving a high degree of cleanliness.

[0044] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The anti-drip shell 7 has an adsorption component inside for restricting one end of the high-pressure oil pipe. The adsorption component includes two snap-fit ​​rings 8, both of which are located inside the anti-drip shell 7 and are spaced apart. The inner circular wall of the snap-fit ​​ring 8 has several negative pressure holes 9. The bottom surface of the anti-drip shell 7 is fixedly mounted with a mounting bracket 10, and the top surface of the mounting bracket 10 is fixedly mounted with a negative pressure pump 11. The bottom surface of the anti-drip shell 7 is fixedly mounted with a dispersion tube 12, and an air suction tube 13 is fixedly mounted on the outside of the dispersion tube 12 and extends into the interior of the dispersion tube 12. The air suction tube 13 is fixedly connected to the air intake port of the negative pressure pump 11. Negative pressure tubes 14 are fixedly mounted on both ends of the dispersion tube 12 and extend into the interior of the dispersion tube 12. The other end of the negative pressure tube 14 is fixedly mounted with a snap-fit ​​ring 8.

[0045] A displacement assembly for moving the high-pressure oil pipe is provided on one side of the anti-drip housing 7. The displacement assembly includes a stepper motor 15, which is fixedly installed on one side of the anti-drip housing 7. Movable holes 16 are opened on both sides of the anti-drip housing 7. A lead screw 17 is movably sleeved inside the right movable hole 16. The drive shaft of the stepper motor 15 passes through one side of the anti-drip housing 7 and is fixedly installed with the lead screw 17. A slide rail 20 is fixedly installed inside the left movable hole 16. A sliding table 18 is movably sleeved inside the movable hole 16. A threaded hole 19 is opened on one side of the right sliding table 18. The threaded hole 19 is threadedly connected to the lead screw 17. The left sliding table 18 is movably sleeved with the slide rail 20.

[0046] When cleaning the inner bore of the high-pressure oil pipe through the negative pressure hole 9, the high-pressure oil pipe is first moved between the two retaining rings 8, and then the high-pressure oil pipe is fitted over the outside of the nozzle 4, so that the two retaining rings 8 are close to the outer wall of the initial end of the high-pressure oil pipe. At the same time, by using the negative pressure pump 11, the negative pressure pump 11 generates negative pressure suction after starting, and then the negative pressure pump 11 transmits the suction to the two negative pressure pipes 14 through the suction pipe 13 and the dispersion pipe 12 respectively, and then to the high-pressure oil pipe through the retaining rings 8 and the negative pressure hole 9. The surface is designed to facilitate the adsorption and clamping of the high-pressure oil pipe. Through the sliding table 18, after the high-pressure oil pipe is restricted by the two clamping rings 8 through negative pressure, the stepper motor 15 is used. The drive shaft of the stepper motor 15 rotates, which drives the lead screw 17 to rotate. The rotation of the lead screw 17 will cause the sliding table 18 to drive the clamping rings 8, the negative pressure pipe 14 and the high-pressure oil pipe to move at a constant speed. This allows the high-pressure oil pipe to move closer to the cleaning box 1, which makes it easier for the nozzle 4 and the nozzle 5 to penetrate into the interior of the high-pressure oil pipe.

[0047] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 A fixed column 21 is fixedly installed on one side of the sliding table 18. A connecting rod 22 is fixedly installed on the outside of the snap ring 8. The connecting rod 22 is movably sleeved with the fixed column 21. A fixed ring 23 is fixedly sleeved on the outer circular wall of the fixed column 21. A movable groove 24 is opened on the outer circular wall of the fixed ring 23. A movable ring 25 is movably sleeved on the outer circular wall of the fixed ring 23. A limit ring 26 is fixedly sleeved on the inner circular wall of the movable ring 25. The limit ring 26 is movably sleeved with the movable groove 24. A thread is opened on the inner circular wall of the movable ring 25. A thread is opened on the outer circular wall of the connecting rod 22. The movable ring 25 is threadedly connected to the connecting rod 22.

[0048] By using the movable ring 25, depending on the size of the high-pressure oil pipe, the operator can rotate the movable ring 25 and move the connecting rod 22. The connecting rod 22 will then move outward through the inside of the fixed column 21, allowing the clamping ring 8 to approach the surface of the high-pressure oil pipe. This facilitates clamping of high-pressure oil pipes of different sizes and enables adaptive adjustment of the aperture of the clamping mechanism.

[0049] Based on the above embodiments, refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 An oil tank 30 is provided on one side of the cleaning tank 1. A high-pressure oil pump 27 is provided between the oil tank 30 and the cleaning tank 1. A fixed pipe 28 is fixedly connected inside the oil outlet of the high-pressure oil pump 27. The fixed pipe 28 is fixedly installed with the cleaning tank 1 and extends into the interior of the cleaning tank 1. An oil suction pipe 29 is fixedly connected inside the oil inlet of the high-pressure oil pump 27. The oil suction pipe 29 is fixedly installed with the oil tank 30 and extends into the interior of the oil tank 30.

[0050] refer to Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 An L-shaped frame 31 is fixedly installed on both sides of the oil tank 30. A drive motor is fixedly installed on one side of the L-shaped frame 31. Sliding holes 47 are opened on both sides of the oil tank 30. Limit grooves 48 are opened on the top and bottom surfaces of the sliding holes 47. A rotating column 32 is movably connected to one side of the L-shaped frame 31. The drive shaft of the drive motor is fixedly installed to the rotating column 32. A first gear 33 is fixedly sleeved on the outer circular wall of the rotating column 32. Two second gears 36 are meshed on the outer circular wall of the first gear 33. A movable rod 34 and a connecting column 35 are fixedly installed on one side of the two second gears 36. A movable frame 37 is provided on one side of the first gear 33. Two limit grooves 48 are opened on one side of the movable frame 37. Rotating holes 38, movable frame 37 and rotating column 32 are fixedly installed. The two rotating holes 38 are respectively movably connected to movable rod 34 and connecting column 35. A pushing column 39 is movably connected to the outer circular wall of the connecting column 35. A connecting arm 40 is fixedly installed on one side of the pushing column 39. A moving block 41 is slidably connected inside the sliding hole 47. Limiting blocks 42 are fixedly installed on the top and bottom surfaces of the moving block 41. The limiting blocks 42 are slidably connected to the limiting groove 48. An installation column 43 is fixedly installed on one side of the moving block 41. A moving arm 44 is movably connected to the outer circular wall of the installation column 43. A cleaning column 45 is fixedly installed on one side of the moving arm 44. Several scrapers 46 are fixedly installed on the outer circular wall of the cleaning column 45.

[0051] refer to Figure 1 , Figure 7 , Figure 8 and Figure 9 An inclined platform 52 is fixedly installed inside the oil tank 30. A servo motor 49 is fixedly installed on the bottom surface of the inclined platform 52. A rotating column 50 is fixedly installed on the top surface of the drive shaft of the servo motor 49. The rotating column 50 passes through the bottom surface of the inclined platform 52. An agitator 51 is provided on the top surface of the inclined platform 52. The agitator 51 is fixedly installed with the rotating column 50. Several agitator columns 53 are fixedly installed on the top surface of the agitator 51.

[0052] By using the fuel tank 30, workers inject diesel fuel into the fuel tank 30 to clean the inside of the high-pressure fuel line. Using the high-pressure fuel pump 27, the diesel fuel inside the fuel tank 30 is drawn out through the extraction pipe 29 and injected into the cleaning tank 1 through the fixed pipe 28, facilitating the filling of the cleaning tank 1 and the nozzle 4. With the first gear 33 in place, after the diesel fuel is injected into the fuel tank 30, the scraper 46 is positioned at the diesel fuel level. Then, using the drive motor, the drive shaft rotates, causing the rotating column 32 and the first gear 33 to rotate. The first gear 33 then meshes with and drives two second gears 36 to rotate. At this time, the two second gears 36 rotate around the outside of the first gear 33. The movable rod 34 and the connecting column 35 rotate in a circular motion, which in turn drives the movable frame 37 and the pushing column 39 to rotate. Since the movable frame 37 is triangular, one corner of which is connected to the connecting column 35 and the pushing column 39, the position of the pushing column 39 will change when the movable frame 37 rotates. When the position of the connecting column 35 rotates closer to the upper position, the movable frame 37 will push the pushing column 39 and drive the connecting arm 40, the moving block 41, the cleaning column 45 and the scraper 46 to move in a straight line. Then, the rotation of the movable frame 37 can cause the pushing column 39 to drive the moving block 41 and the moving arm 44 to move back and forth in a straight line, which can allow the scraper 46 to scrape the surface of the diesel fuel, thereby facilitating the scraping and cleaning of the surface of the diesel fuel after it enters the fuel tank 30, and automatically cleaning the scum on the surface of the fuel in the fuel tank.

[0053] With the agitator 53 in place, when diesel fuel enters the oil tank 30, the servo motor 49 drives the rotating column 50, agitator 51 and agitator 53 to rotate, thereby facilitating the agitation of diesel fuel and preventing it from settling and becoming locally viscous.

[0054] Working principle: Please refer to Figures 1-10As shown, diesel fuel is injected into the cleaning tank 1, and then a high-pressure oil pipe is fitted over the nozzle 4. The diesel fuel in the cleaning tank 1 is then injected into the nozzle 4 through the installation pipe 3. The diesel fuel is then sprayed out through the nozzle 5 and several nozzles 6. At this time, the diesel fuel is directly sprayed into the interior of the high-pressure oil pipe. Since the nozzles 6 diffuse outward in a scattering manner and the opening angle of the nozzles 6 is aligned with the inner wall of the high-pressure oil pipe, the diesel fuel is completely sprayed onto the inner wall of the high-pressure oil pipe, which facilitates the washing away of impurities in the inner wall and gaps of the high-pressure oil pipe, ultimately achieving a high degree of cleanliness.

[0055] When cleaning the inner hole of the high-pressure oil pipe through the set negative pressure hole 9, the high-pressure oil pipe is first moved between the two clamping rings 8, and then the high-pressure oil pipe is sleeved on the outside of the nozzle 4, so that the two clamping rings 8 are close to the outer wall of the initial end of the high-pressure oil pipe. At the same time, by using the negative pressure pump 11, the negative pressure pump 11 will generate negative pressure suction after it is started. Then the negative pressure pump 11 will transmit the suction through the suction pipe 13 and the dispersion pipe 12 to the two negative pressure pipes 14 respectively, and then through the clamping rings 8 and the negative pressure hole 9 to the surface of the high-pressure oil pipe, so as to facilitate the adsorption and clamping of the high-pressure oil pipe.

[0056] With the sliding table 18 in place, after the high-pressure oil pipe is restricted by the two clamping rings 8 through negative pressure, the stepper motor 15 is used. The drive shaft of the stepper motor 15 rotates, which drives the lead screw 17 to rotate. The rotation of the lead screw 17 will cause the sliding table 18 to drive the clamping rings 8, the negative pressure pipe 14 and the high-pressure oil pipe to move at a constant speed. This allows the high-pressure oil pipe to move closer to the cleaning box 1, which makes it easier for the nozzle 4 and the nozzle 5 to penetrate into the interior of the high-pressure oil pipe.

[0057] With the movable ring 25 in place, depending on the size of the high-pressure oil pipe, the operator can rotate the movable ring 25 and move the connecting rod 22. The connecting rod 22 will then move outward through the inside of the fixed column 21, allowing the clamping ring 8 to approach the surface of the high-pressure oil pipe, thus facilitating the clamping of high-pressure oil pipes of different sizes.

[0058] By using the fuel tank 30, the staff can inject diesel fuel into the fuel tank 30 to clean the inside of the high-pressure oil pipe. After the high-pressure oil pump 27 is running, it will draw out the diesel fuel inside the fuel tank 30 through the oil extraction pipe 29 and inject it into the cleaning box 1 through the fixed pipe 28, which will facilitate the oiling of the cleaning box 1 and the nozzle 4.

[0059] With the first gear 33 in place, after diesel fuel is injected into the fuel tank 30, the scraper 46 is positioned at the surface of the diesel fuel. Then, by using a drive motor, the drive shaft of the drive motor rotates, causing the rotating column 32 and the first gear 33 to rotate. The first gear 33 then meshes with and drives two second gears 36 to rotate. At this time, the two second gears 36 rotate around the outside of the first gear 33. Consequently, the movable rod 34 and the connecting column 35 drive the movable frame 37 and the pushing column 39 to rotate. Since the movable frame 37 is triangular, one corner of it... The connecting column 35 and the pushing column 39 are connected. When the movable frame 37 rotates, it changes the position of the pushing column 39. When the position of the connecting column 35 rotates closer to the upper position, the movable frame 37 pushes the pushing column 39 and drives the connecting arm 40, the moving block 41, the cleaning column 45 and the scraper 46 to move in a straight line. Then, the movable frame 37 rotates so that the pushing column 39 drives the moving block 41 and the moving arm 44 to move in a straight line back and forth. This allows the scraper 46 to scrape the surface of the diesel fuel, which facilitates scraping and cleaning the surface of the diesel fuel after it enters the fuel tank 30.

[0060] With the agitator 53 in place, when diesel fuel enters the oil tank 30, the servo motor 49 drives the rotating column 50, agitator 51 and agitator 53 to rotate, thereby facilitating the agitation of the diesel fuel and preventing it from becoming viscous after being left to stand for a long time.
