Clearing robot for pipeline surface adhesive contaminants

Abstract

The invention discloses a clearing robot for pipeline surface adhesive contaminants and belongs to the technical field of robot preparation. The clearing robot for the pipeline surface adhesive contaminants comprises an arc-shaped shell. A wheel-type moving mechanism used for enabling the arc-shaped shell to move onto a to-be-cleaned pipeline is arranged on the inner side of the arc-shaped shell, and a vector propelling mechanism used for propelling the arc-shaped shell to move along the to-be-cleaned pipeline, a fixing device used for fixing the arc-shaped shell to the to-be-cleaned pipeline, a high-pressure water gun system used for cleaning the to-be-cleaned pipeline, a water gun slewing mechanism used for adjusting the radial position of a water gun, at the to-be-cleaned pipeline, of the high-pressure water gun system and a water gun position and posture adjusting mechanism arranged on the water gun slewing mechanism and used for adjusting the position and posture of the water gun are arranged on the arc-shaped shell. According to the clearing robot for the pipeline surface adhesive contaminants, efficient and comprehensive clearing for the surface contaminants of the to-be-cleaned pipeline can be achieved.

Description

technical field [0001] The invention relates to the technical field of robot preparation, in particular to a robot for cleaning up attachments on the surface of pipelines. Background technique [0002] In recent decades, with the continuous development of my country's offshore oil fields and the development of the offshore oil industry, the wellhead platform, as an important equipment in offshore oil extraction operations, has played an increasingly important role in modern ocean development. However, a large number of marine organisms will be adsorbed on the jacket of the wellhead platform in the seawater full immersion area and tidal range area for a long time. The attached marine organisms change the roughness and damping coefficient of the jacket surface, increase the surface area of ​​the jacket, and also increase the total weight of the jacket, so that the jacket can bear greater weight loads, wave loads, or ocean current forces , the stability of the platform, that i...

Problems solved by technology

At the same time, the long-term attachment of marine organisms to the surface of the jacket also intensifies the corrosion of the wellhead platform by the marine environment, reduces the smoothness of the conduit wall, and increases the average drift of waves in the surge, sway, and yaw directions of the column legs. force, which poses a huge threat to safe production, so the wellhead platform jacket needs to be cleaned regularly

[0003] At present, our country's cleaning method for marine organisms attached to the jacket of the offshore wellhead platform still mainly relies on divers to dive into the seabed and use water jets to clean the marine organisms. However, the efficiency of manual cleaning operations is low, and a lot of manpower and material resources are wasted.

In addition, specific cleaning equipment is used to clean the offshore wellhead platform. Compared with manual cleaning, this method is more efficient, but it is greatly affected by environmental factors and is limited to a certain extent.
