Abstract
Description
Technical Field
[0001] The embodiment of the utility model relates to the technical field of pipeline maintenance, and particularly relates to a submarine pipeline maintenance device. Background Art
[0002] A submarine pipeline is a pipeline that continuously transports a large amount of oil under the sea through a closed pipeline. It is a main component of the offshore oilfield development and production system and is also the fastest, safest, and most economical and reliable offshore oil and gas transportation method. Such pipelines are usually located deep under the sea. During long-term use, the surface of some parts of the pipeline is prone to damage under external influence, and it is necessary for workers to dive into the sea to repair it. For example, a submarine pipeline maintenance device disclosed in the prior art publication number (CN216643492U). When the cleaning fan blades arranged on one side of the lighting device through the shaft sleeve move along with the maintenance chamber, the cleaning fan blades themselves will come into contact with the seabed water source. Driven by the water source, the cleaning fan blades will rotate by themselves. At this time, the cleaning scraping pads on the side of the cleaning fan blades corresponding to the lighting device will rotate along with the cleaning fan blades to frictionally clean the lens end of the lighting device, thereby ensuring the clarity of the lens end of the lighting device itself, improving the working range vision of the maintenance chamber itself, and facilitating the maintenance and repair of the maintenance chamber.
[0003] When the above device is in use, the cleaning fan blades rotate to drive the cleaning scraping pads to clean the lighting device. However, since the pipeline is located in the seabed sediment, it is impossible to quickly lift the damaged part of the pipeline, which is inconvenient for pipeline maintenance and increases the difficulty of maintenance operations for workers.
