Underwater robot for submarine pipeline cutting

Abstract

The invention discloses an underwater robot for submarine pipeline cutting. The underwater robot is mainly used for cutting submarine badly broken petroleum pipelines and comprises an ROV (remotely-operated vehicle) body, two cutting mechanisms, supporting legs and a small auxiliary manipulator, the ROV body comprises a frame, a buoyancy block, a propeller, a seven-degree-of-freedom manipulator, a five-degree-of-freedom manipulator, an underwater illumination device, a camera shooting device and a hydraulic electric control device, the supporting legs are uniformly distributed on two sides of the submarine pipeline cutting robot, a center line of the supporting legs is coincided with that of the cutting mechanisms, so that the ROV body is supported, the small auxiliary manipulator is connected below the submarine pipeline cutting robot through bolts and positioned in middle of the cutting mechanisms, the cutting mechanisms are fixed in the rearward front of the bottom of the submarine pipeline cutting robot through bolts, the cutting mechanisms and a pipeline are positioned by a positioning hydraulic cylinder, and the broken pipelines are cut by controlling rotation of a water cutter mechanism. The underwater robot can be automatically operated in deep water areas or special environments.

Description

technical field [0001] The invention relates to an underwater operation device for cutting and processing severely damaged oil pipelines on the seabed. Background technique [0002] ROV, or Unmanned Remotely Operated Vehicle, is an underwater robot used for underwater observation, inspection and construction. There are abundant biological resources, mineral resources and marine resources in the ocean. So far, the developed marine resources only account for a small part of the total. Countries have increased the drilling and exploitation of offshore oil, and the laying length of submarine pipelines has also increased. In order to ensure the normal production of underwater oil and gas, it is necessary to cut and replace pipelines with serious damage. Existing underwater pipeline cutting and replacement operations are performed manually by using mechanical work, which not only takes a lot of time, but also has high labor intensity and high safety risks. With the increase of ...

AI Technical Summary

Problems solved by technology

Existing underwater pipeline cutting and replacement operations are performed manually by using mechanical work, which not only takes a lot of time, but also is labor-intensive and has high safety risks

With the increase of water depth, it is difficult for artificial diving to reach the operation area, which directly affects the failure of timely cutting and replacement of damaged pipelines
