[0008] In the above technical solution, further, a No. 1 motor is fixedly connected inside the base, and an output end of the No. 1 motor is fixedly connected to one end of a screw rod.
[0009] In the above technical solution, further, the driving mechanism includes a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a toothed disc, one side of the toothed disc is meshed with a bevel gear, the end of the bevel gear away from the toothed disc is fixedly connected to a pinion, and the pinion and the bevel gear are both rotatably connected to the outer wall of the base.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the staff can place the device inside the pipeline, and then the driving mechanism will drive the device to move inside the pipeline. During the movement, the liquid pump can draw the paint inside the liquid storage tank to the nozzle, and then the nozzle can spray the paint inside the liquid storage tank onto the inner wall of the pipeline. If the staff needs to spray pipelines with different inner wall diameters, the staff can start motor No. 1.

Through the meshing between the pinion and the crown gear, the crown gear will rotate when the toothed disc rotates. Since the crown gear and the roller at the end of the No. 1 support rod are connected by a belt drive, the crown gear will drive the roller at the end of the No. 1 support rod to rotate through the belt drive, thereby providing power for the base to move inside the pipeline. Through this design, the entire equipment can be automatically towed without the need for manual towing by the operator, so when dealing with some longer pipeline spraying, its spraying efficiency can be greatly improved.
[0016] 3. In the present invention, when the rotating shaft rotates, it will drive the three connecting rods to rotate. Since the disc and the mounting block are rotatably connected, the rotating shaft will drive the three cleaning brushes to rotate simultaneously to complete the cleaning of the inner wall of the pipe, so as to improve the adhesion effect of the paint on the inner wall of the pipe after spraying. In addition, during the movement of the moving block inside the base, the fixed rod will slide relative to the base. During the sliding of the fixed rod, the pushing rod will push the cleaning brush. Since the connecting rod is provided with a corresponding inclined groove, the distance between the cleaning brush and the base will change after the cleaning brush is pushed by the pushing rod. Through this design, the cleaning brush can clean the inner wall of the pipe while following the change of the distance between the roller and the base, so as to meet the cleaning requirements of the inner walls of pipes with different diameters.

[0023] Embodiment 2 like Figure 1 - Figure 6A spraying equipment for electromechanical engineering pipeline processing is shown, and the driving mechanism 3 includes a rotating shaft 31, and a toothed disc 32 is fixedly connected to the outer wall of the rotating shaft 31, and a bevel gear 33 is meshed on one side of the toothed disc 32, and a pinion 34 is fixedly connected to the end of the bevel gear 33 away from the toothed disc 32, and the pinion 34 and the bevel gear 33 are both rotatably connected to the outer wall of the base 1, and a crown gear 35 is meshed on one side of the pinion gear 34, and the crown gear 35 is rotatably connected to the No. 1 support rod 23, and a belt 36 is transmission-connected between the crown gear 35 and the roller 25 rotatably connected to the end of the No. 1 support rod 23, and a No. 2 motor 37 is fixedly connected to the inside of the base 1, and the output end of the No. 2 motor 37 is fixedly connected to the end of the rotating shaft 31.

Since the toothed disc 32 and the bevel gear 33 are meshed, the three bevel gears 33 will rotate simultaneously when the toothed disc 32 rotates. Since the bevel gear 33 and the pinion gear 34 are fixedly connected, the pinion gear 34 will also rotate when the bevel gear 33 rotates. Through the meshing between the pinion gear 34 and the crown gear 35, the crown gear 35 will rotate when the toothed disc 32 rotates. Since the crown gear 35 and the roller 25 at the end of the No. 1 support rod 23 are connected by a belt 36, the crown gear 35 will drive the roller 25 at the end of the No. 1 support rod 23 to rotate when it rotates, thereby providing power for the movement of the base 1 inside the pipe.
[0025] Embodiment 3 like Figure 1 - Figure 6 A spraying device for electromechanical engineering pipeline processing is shown, and the cleaning mechanism 4 includes a fixed rod 41, which is fixedly connected to one side of the moving block 22, and the fixed rod 41 is slidably connected to the inside of the base 1. The end of the fixed rod 41 located outside the base 1 is fixedly connected to a mounting block 42, and the mounting block 42 is slidably connected to the rotating shaft 31. A disc 43 is rotatably connected to one side of the mounting block 42, and the disc 43 is slidably connected to the rotating shaft 31. A push rod 44 is rotatably connected to one side of the disc 43. A connecting rod 46 is fixedly connected to the outside of the rotating shaft 31, and a cleaning brush 45 is slidably connected to the inside of the connecting rod 46. The end of the push rod 44 away from the disc 43 is rotatably connected to the outside of the cleaning brush 45.
[0026] In this embodiment, when the rotating shaft 31 rotates, it will drive the three connecting rods 46 to rotate. Since the disc 43 and the mounting block 42 are rotatably connected, the rotating shaft 31 will drive the three cleaning brushes 45 to rotate simultaneously to complete the cleaning of the inner wall of the pipe, so as to improve the adhesion effect of the paint on the inner wall of the pipe after spraying. In addition, during the movement of the moving block 22 inside the base 1, the fixed rod 41 will slide relative to the base 1. During the sliding of the fixed rod 41, the pushing rod 44 will push the cleaning brush 45. Since the connecting rod 46 is provided with a corresponding inclined groove, the distance between the cleaning brush 45 and the base 1 will change after the cleaning brush 45 is pushed by the pushing rod 44.

[0027] Working principle: The staff can place the device inside the pipeline and start the No. 1 motor 26 and the No. 2 motor 37. After starting, the No. 1 motor 26 will drive the screw 21 to rotate. When the screw 21 rotates, it will drive the moving block 22 to move inside the base 1. When the moving block 22 moves in the direction of the No. 1 motor 26, the angle between the No. 1 support rod 23 and the No. 2 support rod 24 will decrease, so that the distance between the roller 25 and the base 1 will gradually increase. By adjusting the distance between the roller 25 and the base 1, the base 1 can adapt to pipelines of different diameters. When the output end of the No. 2 motor 37 rotates When the rotating shaft 31 is rotated, the rotating shaft 31 will be driven to rotate. During the rotation of the rotating shaft 31, the toothed disc 32 will be driven to rotate. Because the toothed disc 32 and the bevel gear 33 are meshed, the three bevel gears 33 will rotate at the same time when the toothed disc 32 rotates. Because the bevel gear 33 and the pinion gear 34 are fixedly connected, the pinion gear 34 will also rotate when the bevel gear 33 rotates. Through the meshing between the pinion gear 34 and the crown gear 35, the crown gear 35 will rotate when the toothed disc 32 rotates. Because the crown gear 35 and the roller 25 at the end of the No. 1 support rod 23 are connected by a belt 36, the crown gear 35 rotates through the transmission of the belt 36. When the rotating shaft 31 rotates, the roller 25 at the end of the No. 1 support rod 23 will be driven to rotate, thereby providing power for the movement of the base 1 inside the pipeline. During the movement, the liquid pump 13 can pump the paint inside the liquid storage tank 11 to the nozzle 15, and then the nozzle 15 can spray the paint inside the liquid storage tank 11 onto the inner wall of the pipeline. In addition, when the rotating shaft 31 rotates, it will drive the three connecting rods 46 to rotate. Because the disc 43 and the mounting block 42 are rotatably connected, the three cleaning brushes 45 will be driven to rotate at the same time when the rotating shaft 31 rotates to complete the cleaning of the inner wall of the pipeline, so as to improve the adhesion of the paint to the inner wall of the pipeline after spraying. Adhesion effect. In addition, during the movement of the moving block 22 inside the base 1, the fixed rod 41 will slide relative to the base 1. During the sliding of the fixed rod 41, the pushing rod 44 will push the cleaning brush 45. Since a corresponding inclined groove is provided on the connecting rod 46, the distance between the cleaning brush 45 and the base 1 will change after the cleaning brush 45 is pushed by the pushing rod 44. Through this design, the cleaning brush 45 can clean the inner wall of the pipe while changing with the change of the distance between the roller 25 and the base 1, so as to meet the cleaning needs of the inner walls of pipes with different diameters.
