Technical Field

[0001] The utility model relates to the technical field of cleaning devices for the inner walls of ship pipelines, and particularly relates to a cleaning device for the inner walls of ship pipelines. Background Technique

[0002] Ship pipelines are the pipelines used on ships to connect various mechanical equipment and are used to convey working media such as water, oil, and gas. There are two major categories of ship pipelines, power pipelines and ship system pipelines. Power pipelines are various pipelines serving the main engine and auxiliary engines, including fuel pipelines, lubricating oil pipelines, cooling water pipelines, compressed air pipelines, exhaust pipelines, waste heat pipelines, etc. Ship system pipelines are for improving the anti-sinking property and stability of the ship and to meet the normal living needs of crew members and passengers. There are many ship systems, such as a water supply system for supplying seawater and fresh water to the whole ship, a ballast water system for adjusting the ship's ballast, a bilge water drainage system for discharging bilge water, a compressed air system for supplying compressed air to the whole ship, a fire fighting system for fire extinguishing, and so on.

[0003] In the prior art, the inner walls of ship pipelines are prone to docking dirt after use and need to be cleaned regularly. When cleaning the inner walls of ship pipelines, a high-pressure water gun is mostly used in combination with a cleaning agent for flushing, which is relatively wasteful of water resources. For this reason, we propose a cleaning device for the inner walls of ship pipelines. Content of the Utility Model

When the grinding piece is against the inner wall of the pipeline, the outer end of the limit rod is buckled in the groove of the grinding rod, and the grinding rod is limited and fixed in cooperation with the first torsion spring. When the pipeline driving vehicle moves along the inner wall of the ship pipeline, the motor rotates to drive the grinding frame to make a circular motion, so that the grinding piece grinds the inner wall of the ship pipeline.
