Description

Technical Field

[0001] The utility model relates to the technical field of submarine pipeline cleaning, in particular to a submarine high-pressure water pipeline cleaning device. Background Art

[0002] Submarine pipelines are sealed pipes that continuously transport large amounts of oil on the seabed. They are a major component of offshore oilfield development and production systems and are currently the fastest, safest, most economical and reliable way to transport offshore oil and gas. After a period of use, submarine organisms will attach to the outside of the pipeline or rust will occur due to erosion by ocean currents. These problems will shorten the service life of the submarine pipeline. Therefore, the outside of the submarine pipeline must be cleaned and maintained frequently. Given the special location of the pipeline, submarine pipeline cleaning is generally carried out using automated machinery.

[0003] A Chinese utility model with publication number CN219560779U discloses a novel submarine oil and gas pipeline cleaning device. When the device moves on the submarine oil and gas pipeline as a whole, the cutting blade can remove the attachments on the surface of the submarine oil and gas pipeline, and then the bristles can perform a second cleaning to prevent the removed attachments from accumulating on the surface of the submarine oil and gas pipeline, thereby preventing them from attaching to it again after a period of time.

[0004] This device uses a scraper driven by the device's movement to scrape and clean the pipe surface. However, since pipe surface debris often consists of shellfish, seaweed, and other debris, scraping alone not only results in poor cleaning results but also reduces the device's movement efficiency, extending the cleaning process. To address this issue, we have developed a submarine high-pressure water pipe cleaning device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, the utility model provides a technical solution: a high-pressure water pipeline cleaning device for the seabed, comprising a main ring body 1, two cleaning ring bodies 2, a drive assembly and a water supply assembly.

[0027] A walking assembly for moving the main ring body 1 on the pipeline is provided in the main ring body 1. The walking assembly includes a mounting block 3 fixedly connected to the main ring body 1, a first electric push rod 4 installed on the mounting block 3, and a support plate 5 installed on the first electric push rod 4. Two symmetrical support wheels 6 are installed on the support plate 5.

[0028] The telescopic end of the first electric push rod 4 is used to drive the abutment plate 5 to move, so that the abutment wheel 6 on the abutment plate 5 can abut against the pipeline, and the main ring body 1 can slide on the pipeline through the abutment wheel 6.

[0029] The walking assembly also includes a moving wheel seat 7 fixedly connected to the abutment plate 5, and a waterproof motor 8 is installed on the moving wheel seat 7. The moving wheel seat 7 is located between the two abutment wheels 6. The output shaft of the waterproof motor 8 drives the roller inside the moving wheel seat 7 to rotate, which can provide a rotational driving force for the roller inside the moving wheel seat 7 and provide a moving force for the main ring body 1 to move on the pipeline.

[0030] The two cleaning ring bodies 2 are respectively rotatably connected to the two ends of the main ring body 1. An annular tube 9 is installed in each cleaning ring body 2. The two annular tubes 9 are fixedly connected to high-pressure nozzles 10 in a circular array. There is a distance between adjacent high-pressure nozzles 10. Gears 11 are fixedly connected to the two cleaning ring bodies 2.

[0031] The driving assembly is arranged on the main ring body 1, and is used to drive the two cleaning ring bodies 2 to rotate in a small circle on the main ring body 1 through the gear 11. The driving assembly includes a first support frame 12 fixedly connected to the main ring body 1, and a second electric push rod 13 is fixedly connected to the first support frame 12. The telescopic end of the second electric push rod 13 is fixedly connected to a rack 14, and the rack 14 is meshed with the two gears 11. Two guide rods 15 are slidably connected to the rack 14, and both ends of the two guide rods 15 are installed on the first support frame 12.

[0032] By driving the rack 14 to move through the telescopic end of the second electric push rod 13, the rack 14 can simultaneously drive the two cleaning ring bodies 2 to rotate on the main ring body 1 through the gear 11, and the reciprocating movement of the rack 14 can enable the cleaning ring body 2 to perform a small reciprocating rotation motion on the main ring body 1, thereby increasing the cleaning area of the high-pressure nozzle 10 on the pipeline.

[0033] The water supply assembly is arranged on the main ring body 1 and is used to provide high-pressure water to the two annular pipes 9 at the same time. The water supply assembly includes a second support frame 16 fixedly connected to the main ring body 1 and a water pump 17 installed on the second support frame 16. The output ends of the water pump 17 are fixedly connected to the two annular pipes 9 through pipes.

[0034] The seawater is filtered and pressurized by the water pump 17 and transported to the inside of the annular pipe 9 , and a high-pressure water column is formed by the high-pressure nozzle 10 to clean the pipe surface.

[0035] Working principle: First, multiple first electric push rods 4 are started synchronously, and the telescopic end of the first electric push rod 4 drives the abutment plate 5 to move, so that the abutment wheel 6 can be abutted against the pipe. Then, the waterproof motor 8 is started to provide driving force for the rolling in the movable wheel seat 7, so that the main ring body 1 can be moved on the pipe. At the same time, the water pump 17 is started, so that the water pump 17 filters the seawater and pressurizes it to the inside of the annular tube 9, and forms a high-pressure water column through the high-pressure nozzle 10 to clean the pipe surface. The second electric push rod 13 can also be started, so that the telescopic end of the second electric push rod 13 drives the rack 14 to move, so that the rack 14 can simultaneously drive the two cleaning ring bodies 2 to rotate on the main ring body 1 through the gear 11, and through the reciprocating movement of the rack 14, the cleaning ring body 2 can perform a small reciprocating rotation on the main ring body 1, thereby increasing the cleaning area of the high-pressure nozzle 10 on the pipe. In the process of cleaning the pipe, not only the cleaning effect of the pipe is better, but also the movement of the device will not be affected, thereby improving the cleaning efficiency of the pipe.
