An underwater pipeline grinding device

Abstract

The invention discloses an underwater pipe polishing device for cleaning underwater seabed pipe protective coating layers. The underwater pipe polishing device comprises three parts of an equipment frame structure, a pipe clamping mechanism and a walk pipe brushing mechanism. The underwater auxiliary positioning is firstly performed on the underwater pipe polishing device through a ROV (remotely operated underwater vehicle), so that the equipment frame structure and target pipes are primarily positioned; then, the pipes are clamped by the pipe clamping mechanism, so that the device and the target pipes are totally positioned; the walk pipe brushing mechanism drives a steel wire brush roller to peripherally move; and finally, the steel wire brush roller is rotated to clean coating layers onthe surfaces of the pipes. The underwater pipe polishing device can be fixed on the pipes in multiple positions, and meanwhile, can realize 180-degree rotation through gear transmission, so that thecleaning efficiency of the coating layers and rust on the surfaces of the pipes is improved, and the engineering progress is accelerated.

Description

technical field [0001] The invention relates to a device capable of cleaning underwater pipeline coatings and rust, in particular to an underwater pipeline grinding device. Background technique [0002] In the complex and harsh seabed environment, a series of factors such as seawater corrosion, seabed organism adhesion, and anchor impact will cause chemical or physical damage to submarine oil pipelines, resulting in crude oil leakage, which will cause huge damage to the environment. Submarine pipelines need to be repaired in case of emergencies. There are many maintenance methods at present, but because submarine pipelines are often covered with various protective coatings, the coating on the surface of the pipeline needs to be removed before maintenance. [0003] Traditional coating cleaning methods generally use underwater manual operations or underwater ROV manipulators with brushes. Manual operation is that divers carry coating cleaning tools to manually clean the pipel...

AI Technical Summary

Problems solved by technology

Manual operation is that divers carry coating cleaning tools to manually clean the pipeline coating. This method is dangerous in the working environment and has low working efficiency; the underwater ROV manipulator with brush operation method requires high skills of the operator and low working efficiency

The operating efficiency of the two methods cannot meet the operating requirements of the current emergency
