[0027] Firstly, as shown in Figure 1 , attached Figure 4 and attached Figure 5As shown, when cleaning the inner wall of the oil injection pipe, the diameter of the inner wall of the injection pipe body 2 and the actual condition of the dirt on the inner wall are first adjusted. Then, the left end of the mounting rod 3 is fixedly installed with the left end inside the placement chamber 1, and the right end of the mounting rod 3 is set in a rotating state. Then, the mounting rod 3 is rotated according to the actual condition inside the injection pipe body 2. Then, the right end of the mounting rod 3 is set in a threaded state, and the inner wall of the second hinge ear 6 is connected to the right end of the mounting rod 3 by a thread. Then, the rotation of the mounting rod 3 drives the second hinge ear 6 to slide on the rod of the mounting rod 3. Then, the hinge rod 7 is also tilted and connected to the inner wall of the second hinge ear 6. The first hinge lug 5 on the left end of the mounting rod 3 and the second hinge lug 6 on the right end of the mounting rod 3 are rotatably connected together. The hinge rods 7 are arranged in a circular array about the center point of the mounting rod 3. The mounting plate 8 is rotatably connected to one end of the hinge rod 7. The cleaning brush 9 is fixedly installed inside the mounting plate 8. By rotating the mounting rod 3, the second hinge lug 6 drives the mounting plate 8 through the hinge rod 7 to form a telescopic structure, so that the diameter of the cleaning brush 9 is consistent with the inner wall of the water injection pipe body 2. By rotating the right end of the mounting rod 3, it can be adjusted according to the pipe diameter and the actual situation of the inner wall of the pipe.

[0028] As attached Figure 1 Appendix Figure 2 and attached Figure 3As shown in the middle, after the pipe adjustment according to the diameter of the water injection pipe body 2 is completed, the rod body of the water injection pipe body 2 is further inserted into the inside of the placement warehouse 1. Since the left and right ends of the inner bottom of the placement warehouse 1 are both fixedly installed with the first arc-shaped plate 10, and the first arc-shaped plate 10 is arranged in a semi-arc structure state, and the inside of the first arc-shaped plate 10 is also rotatably connected with the rotating wheel 14, and the rotating wheel 14 is arranged in an annular array state about the center point of the first arc-shaped plate 10, the water injection pipe body 2 is sleeved outside the rod body of the mounting rod 3, so that the cleaning brush 9 is tightly attached to the inner side wall of the water injection pipe body 2, and the lower end of the water injection pipe body 2 is also placed in the semi-arc body of the first arc-shaped plate 10, so that the bottom of the water injection pipe body 2 is attached to the rotating wheel 14 inside the first arc-shaped plate 10, and the lower end of the water injection pipe body 2 is also rotatably connected with the rotating wheel 14. After the water injection pipe body 2 is placed, the rotating threaded rod 13 is further rotated. Since the inner side wall of the placement warehouse 1 is connected with the threaded rod 13 through threads, and the lower end of the threaded rod 13 is rotatably connected with the second arc-shaped plate 11, and the second arc-shaped plate 11 is fixed to the inner top of the placement warehouse 1 through the telescopic rod 12 in a telescopic structure, so that the threaded rod 13 drives the second arc-shaped plate 11 to form a lifting structure, and then the second arc-shaped plate 11 is also arranged in a semi-arc structure state, and the inside of the second arc-shaped plate 11 is also arranged in an annular array state with the rotating wheel 14. The lifting of the rotating wheel 14 driven by the second arc-shaped plate 11 makes the rotating wheel 14 precisely attached to the top of the water injection pipe body 2, so that the water injection pipe body 2 is fixed by the cooperation between the first arc-shaped plate 10 and the second arc-shaped plate 11, and a stable working state is provided for the water injection pipe body 2, reducing the risk of displacement or falling during cleaning;

[0029] As shown in the accompanying Figure 1 and the accompanying Figure 2As shown in the middle, when the water injection pipe body 2 is fixed outside the mounting rod 3, the left and right ends of the mounting rod 3 are fixed with high-pressure nozzles 4, the high-pressure nozzles 4 can be connected with the external water source, and then the external water source and the high-pressure nozzles 4 are connected together, so that the inside wall of the water injection pipe body 2 can be washed through the high-pressure nozzles 4, and then the front and rear ends of the inside bottom of the storage bin 1 are rotatably connected with the rotating rollers 15, and the rotating rollers 15 are attached to the outside wall of the water injection pipe body 2, and then the motor 16 is started, and then the front synchronous pulley 17 in the storage bin 1 and the rear synchronous pulley 17 in the storage bin 1 are connected together through the belt 18, so that the rotation of the motor 16 can be matched between the synchronous pulley 17 and the belt 18, so that the rotating rollers 15 at the front and rear ends of the storage bin 1 are synchronously rotated, and the rotating rollers 15 drive the water injection pipe body 2 to rotate, because the water injection pipe body 2 is closely attached to the rotating wheel 14, so that the water injection pipe body 2 rotates between the first arc-shaped plate 10 and the second arc-shaped plate 11, and the cleaning brush 9 is closely attached to the inside wall of the water injection pipe body 2, so that the cleaning brush 9 can clean the inside wall of the water injection pipe body 2 through the rotation of the water injection pipe body 2, and the high-pressure nozzles 4 can also wash the inside wall of the water injection pipe body 2 through the rotation of the water injection pipe body 2, so that the rotation of the water injection pipe body 2 can reduce the dependence on the operator, maximize the cleaning speed, and ensure the best cleaning effect.
