A submarine pipeline detection type underwater robot

Abstract

The utility model relates to a submarine pipeline detection type underwater robot. It is used for accurate detection of underwater oil pipelines. The underwater robot (ROV) includes an ROV body, a fixed pipeline clamp device and a chain-type pipeline horizontal detection device; the ROV body serves as a carrier to provide power for the clamp device and the detection device; the clamp device passes through a linear guide rail slider mechanism The rotation of the left bracket and the right bracket is converted, thereby driving the rotation of the claws on the bracket, and finally the clamp device is converted into a clamping force on the pipeline, preventing the shaking and swing of the ROV body, and ensuring the reliability of the clamp work. It also ensures that the chain-type pipeline can provide a stable detection environment for the horizontal detection device. In the detection device, the flexible manipulator is equipped with detection equipment to detect the pipeline, and the horizontal rotation detection can be carried out on the basis of detection along the axial direction of the pipeline. At the same time, this kind of underwater robot adopts a flexible manipulator structure that can automatically attach to the pipe wall, and is suitable for most diameter pipes.

Description

Technical field: [0001] The invention relates to an underwater robot used for detecting submarine pipelines. Background technique: [0002] With the continuous development of offshore oil, pipelines, which are equipment for underwater oil transmission, are becoming more and more important. All countries are speeding up the construction of submarine oil and gas pipelines, and the distance required for submarine pipeline transportation is also increasing, and the maximum laying depth can reach thousands of meters. Therefore, regular inspection of pipelines has become particularly important. Underwater pipeline detection is usually carried out by underwater robots equipped with detection equipment. However, due to the complex environment and turbulent ocean currents on the seabed, the detection underwater robots cannot adapt to the complex environment, resulting in inaccurate or unstable detection data. Detection poses many difficulties. At present, most of the submarine pipe...
