Description

Technical Field

[0001] This utility model relates to the field of oil pipeline cleaning technology, and in particular to an oil pipeline inner wall cleaning device. Background Technology

[0002] During transportation, as oil flows through pipelines, a mixture of paraffin wax, gum, solidified oil, sand, and other impurities gradually accumulates on the inner walls of the pipelines, forming a layer that is collectively known as wax deposits. This wax needs to be removed using cleaning equipment.

[0003] Publication number CN221559237U discloses a cleaning and dredging device for oil pipelines. However, during the implementation of this solution, since the spiral head cannot contact the inner wall of the pipeline, it can only drill and loosen larger impurities, but cannot loosen impurities that are tightly attached to the inner wall of the pipeline. Since most impurities are adhered to the inner wall of the pipeline, they cannot be loosened, which increases the burden on the subsequent hanging plate for cleaning the inner wall of the pipeline. Therefore, a pipeline inner wall cleaning device for oil development is proposed. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a pipeline inner wall cleaning device for oil exploration, including a mounting base 1, a scraper 2 fixedly connected to the surface of the mounting base 1, a feeding mechanism at one end of the mounting base 1, and the feeding mechanism has been specifically disclosed in the prior art, so it will not be discussed in detail here. The bottom of the mounting base 1 is provided with casters to facilitate the movement of the device in the pipeline.

[0023] A fixed housing 4 is fixedly connected to the side of the mounting base 1 away from the scraper 2. A rotating housing 5 is rotatably connected to the side of the fixed housing 4 away from the mounting base 1. A rotating disk 7 is fixedly connected to the side of the rotating housing 5 away from the fixed housing 4. A spiral head 6 is rotatably connected to the surface of the rotating disk 7 to drill through large blockages in the pipe, facilitating subsequent cleaning of impurities on the inner wall of the pipe.

[0024] The surface of the spiral head 6 is fixedly connected with mounting blocks 8 arranged equidistantly in a circle. A steel brush is fixedly connected to the top of the mounting block 8 for scrubbing the inner wall of the pipeline. A prying plate 11 with a "Z" shaped cross section is slidably connected inside the mounting block 8 for prying up small impurities adhering to the inner wall of the oil pipeline, so as to reduce the difficulty of subsequent cleaning of impurities by the scraper 2.

[0025] The pry plate 11 is tapered on the side near the rotating disk 7. A limiting plate 9 is fixedly connected to the surface of the pry plate 11 inside the mounting block 8. The surface of the limiting plate 9 is slidably connected to the interior of the mounting block 8. A spring 22 is fixedly connected to the surface of the limiting plate 9. The end of the spring 22 away from the limiting plate 9 is fixedly connected to the interior of the mounting block 8 to reset the pry plate 11.

[0026] The mounting base 1 has a motor 14 fixedly connected inside. The output end of the motor 14 passes through the surface of the fixed shell 4 and is rotatably connected to the inside of the fixed shell 4. The output end of the motor 14 passes through the surface of the rotating disk 7 and is rotatably connected to the inside of the rotating disk 7. The output end of the motor 14 is fixedly connected to the auger head 6, thereby driving the auger head 6 to rotate in the oil pipeline, so that the auger head 6 can successfully drill and break large impurities.

[0027] A ring groove 13 is provided on the side of the rotating disk 7 near the mounting block 8. The inner wall of the ring groove 13 is fixedly connected to abutting blocks 12 arranged equidistantly in a circle. The abutting blocks 12 are conical. An annular storage tank 16 is fixedly connected to the surface of the rotating disk 7 to store cleaning fluid. An annular plate 17 is rotatably connected to the surface of the annular storage tank 16. A bent connecting pipe 15 is fixedly connected to the surface of the annular plate 17. The connecting pipe 15 penetrates the surface of the fixed shell 4 and is fixedly connected to the inside of the fixed shell 4. An infusion pipe 3 penetrating the surface of the scraper 2 is fixedly connected to the inside of the scraper 2. The end of the connecting pipe 15 away from the annular plate 17 is fixedly connected to the end of the infusion pipe 3, so that the external cleaning fluid can be smoothly transported to the annular storage tank 16 through the infusion pipe 3 and the connecting pipe 15, ensuring a continuous supply of cleaning fluid. At the same time, the end of the infusion pipe 3 away from the connecting pipe 15 is connected to a water pump. This has been explained in detail in the comparative document and will not be discussed here.

[0028] Inside the rotating shell 5, there are nozzles 10 arranged equidistantly in a circle, and the nozzles 10 penetrate the surface of the rotating shell 5. One end of the nozzle 10 inside the rotating shell 5 is fixedly connected to the annular liquid storage tank 16, and the nozzles 10 and the interior of the annular liquid storage tank 16 are interconnected, so that the cleaning fluid in the annular liquid storage tank 16 can be smoothly sprayed into the pipeline to clean the pipeline.

[0029] An internal gear ring 18 is fixedly connected to the inner wall of the annular storage tank 16, and an installation shaft 21 is fixedly connected to the inner wall of the fixed shell 4. A second gear 20 is fixedly connected to one end of the installation shaft 21. The surface of the second gear 20 meshes with the inner wall of the internal gear ring 18. A first gear 19 is fixedly connected to the output end of the motor 14. The surface of the first gear 19 meshes with the surface of the second gear 20. Through the meshing between the first gear 19, the second gear 20 and the internal gear ring 18, the motor 14 can smoothly drive the rotating shell 5 and the rotating disk 7 to rotate when starting, so that the nozzle 10 can rotate to clean the inner wall of the oil pipeline, thereby improving the cleaning effect of the device on the inner wall of the oil pipeline.

[0030] Secondly, the bottom of the mounting base 1 is also equipped with a device that can suck out impurities in the oil pipeline, which has been disclosed in the prior art and will not be explained in detail here.

[0031] Working principle: When motor 14 starts, it drives the spiral head 6 to rotate, thereby drilling and breaking large impurities in the oil pipeline. Simultaneously, the rotation of the spiral head 6 drives the mounting block 8 to perform circular motion, allowing the mounting block 8 to scrub the inner wall of the oil pipeline. At the same time, motor 14 drives the first gear 19 to rotate. Through the meshing between the first gear 19 and the second gear 20, and between the second gear 20 and the internal gear ring 18, the annular liquid storage tank 16 is driven to rotate, which in turn drives the rotating disk 7 and the rotating shell 5 to rotate. This causes the nozzle 10 to rotate and spray cleaning fluid onto the inner wall of the pipeline, ensuring that the cleaning fluid can clean the inner wall of the oil pipeline relatively evenly. Furthermore, because the rotation speeds of the rotating disk 7 and the spiral head 6 are different, the spiral head... When the rotating disk 6 and the rotating disk 7 are rotating, the inclined surface of the jacking block 12 presses and pushes the inclined surface of the prying plate 11, and drives the limiting plate 9 to slide in the mounting block 8, compressing the spring 22. At the same time, after the inclined surface of the jacking block 12 separates from the inclined surface of the prying plate 11, the prying plate 11 returns to its original shape under the elastic force of the spring 22. Thus, when the rotating disk 7 and the spiral head 6 rotate relative to each other, the prying plate 11 continuously reciprocates in the mounting block 8, thereby causing the prying plate 11 to continuously pry the impurities adhering to the inner wall of the oil pipeline, loosening the impurities adhering to the inner wall of the oil pipeline. This solves the problem that the spiral head 6 cannot loosen the impurities adhering to the inner wall of the oil pipeline, increasing the difficulty of subsequent cleaning of impurities by the scraper 2.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
