Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, and in particular relates to a complementary cleaning device for dual pipeline cleaning. Background Technology

[0002] Long-term use of oil pipelines often results in severe scaling, wax buildup, and rust, reducing the pipeline's cross-section and impacting transport capacity, necessitating cleaning. One type of existing pipeline pig is equipped with a sealing ring, which is propelled forward by pressure, thus enabling the entire pig to advance. However, this type of pig has the drawback of failing to promptly flush away the removed wax and scale from the pipeline. The removed wax and scale can easily clog the oil pipeline, preventing the pig from continuing its advance. Utility Model Content

[0003] To address the problems in the background technology, this utility model provides a complementary cleaning device for dual pipeline pigs. This utility model uses pressure as a driving force to propel the sealing ring forward while also periodically allowing flushing fluid to flow through the sealing ring. The flushing fluid can flush out the cleaned wax scale from the oil pipeline, preventing the wax scale from accumulating and clogging the oil pipeline.

[0004] The technical solution provided by this utility model is: a complementary cleaning device for dual-unit pipeline cleaning, including a guide head, a mounting rod, a scraper, and a sealing ring. The guide head is located at one end of the mounting rod, and the sealing ring is located at the other end. The scraper is mounted on the mounting rod, which has a fluid flow channel. The two ends of the fluid flow channel are located on the upper and lower sides of the sealing ring, respectively, allowing the fluid to pass over the sealing ring. An electric switching valve, a control panel, and a battery are located at the end of the mounting rod furthest from the guide head. One end of the electric switching valve is connected to the fluid flow channel. The control panel is electrically connected to the electric switching valve, controlling the periodic opening and closing of the electric switching valve. The battery is electrically connected to both the control panel and the electric switching valve, thereby supplying power to both.

[0005] A further technical solution is: there are two scrapers, both of which are mounted on the mounting rod, and the outer diameter of the scraper closer to the guide head is smaller than the outer diameter of the scraper farther from the guide head.

[0006] A further technical solution is that the sealing ring is made of wear-resistant elastic rubber.

[0007] A further technical solution is that the outlet end of the liquid flow channel is an oblique hole.

[0008] A further technical solution is that the scraper includes an annular outer contour and a central mounting ring, and the annular outer contour and the central mounting ring are connected by spokes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This invention uses pressure as the driving force to propel the sealing ring forward while periodically opening and closing the liquid flow channel. This allows the liquid to bypass the sealing ring and flush away the scraped wax deposits, preventing the wax deposits from accumulating and eventually clogging the oil pipeline. When the liquid flow channel is closed, the pressure serves as the driving force for propelling the sealing ring forward; when the liquid flow channel is open, the sealing ring cannot be propelled forward, and the pressure at this time serves as the liquid flow force for flushing the wax deposits, thus achieving the flushing of the wax deposits.

[0011] 2. The scraper and sealing ring of this utility model achieve complementary scraping. The scraper removes most of the wax residue, and the sealing ring cleans the areas missed by the scraper. The two complement each other to ensure excellent cleaning effect.

[0012] 3. This utility model has two scrapers, wherein the outer diameter of the first scraper is smaller than that of the second scraper, so that the two scrapers form a two-stage scraping, avoiding excessive resistance in single-stage scraping. At the same time, the two-stage scraping can make the scraped wax scale smaller in volume, thus making it easier to rinse away. Attached Figure Description

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0016] like Figure 1As shown, this embodiment includes a guide head 1, a mounting rod 6, a scraper, and a sealing ring 5. The guide head 1 is mounted on one end of the mounting rod 6, and the sealing ring 5 is mounted on the other end. The scraper is mounted on the mounting rod 6, which has a fluid flow channel 7. The two ends of the fluid flow channel 7 are located on the upper and lower sides of the sealing ring 5, respectively, allowing the liquid to pass over the sealing ring 5. When the fluid flow channel 7 is closed, the pressure acts as the driving force for the sealing ring 5 to move forward. When the fluid flow channel 7 is open, the sealing ring 5 cannot be pushed forward; the pressure at this time acts as the fluid flow force for flushing the wax deposits, thus achieving the flushing of the wax deposits. This embodiment uses pressure as the driving force to push the sealing ring 5 forward while also periodically opening and closing the fluid flow channel 7, allowing the liquid to bypass the sealing ring 5 and flush the scraped-off wax deposits, preventing the scraped-off wax deposits from accumulating and eventually clogging the oil pipeline.

[0017] To enable the periodic opening and closing of the fluid flow channel 7, an electric switching valve 8, a control panel 9, and a battery 10 are provided at one end of the mounting rod 6 away from the guide head 1. One end of the electric switching valve 8 is connected to the fluid flow channel 7, and the control panel 9 is electrically connected to the electric switching valve 8 to control the periodic opening and closing of the electric switching valve 8. The battery 10 is electrically connected to both the control panel 9 and the electric switching valve 8 to supply power to both.

[0018] To reduce scraping resistance, there are two scrapers, both mounted on the mounting rod 6. The outer diameter of the scraper closer to the guide head 1 is smaller than that of the scraper farther from the guide head 1, thus forming a two-stage scraping process. This avoids excessive resistance in a single-stage scraping process, and the two-stage scraping also makes the scraped-off wax deposits smaller in volume, making them easier to rinse off.

[0019] The sealing ring 5 is made of wear-resistant elastic rubber.

[0020] The outlet end of the liquid flow channel 7 is an oblique hole, which can reduce the liquid flow resistance and reduce the liquid flow power loss when rinsing wax scale.

[0021] The scraper includes an annular outer contour 2 and a central mounting ring 4. The annular outer contour 2 and the central mounting ring 4 are connected by spokes 3. The oblique hole is located upstream of the spokes 3. The rinsing fluid passes through the gap between the spokes 3 of the scraper, thereby rinsing away the wax scale.

[0022] The scraper and sealing ring 5 of this invention achieve complementary scraping. The scraper removes most of the wax residue, and the sealing ring 5 cleans the areas that the scraper misses. The two complement each other to ensure a good cleaning effect.
