An underwater robot for pipeline flaw detection

Abstract

The invention relates to the technical field of an underwater robot and is to provide an underwater robot for pipeline flaw detection. The underwater robot comprises a structure system, an autopilot system and a detection system. The structure system comprises a carrier framework, a buoyance material, a pressure-resistant housing, a propeller and a battery. The autopilot system is arranged in the carrier framework and comprises an autopilot module, an autonomous navigation module, a motor drive module, a sensor module, a communication module, an emergency module and a communication electronic circuit. The detection system is arranged on the carrier framework. The underwater robot is small in size, light in weight and convenient to operate, does not need other assistant devices of a crane and a ship and the like, and can be operated by a person without any professional background; the underwater robot is low in cost, has clear purpose and use value and is convenient to popularize; and the underwater robot is easy to process and produce, is simple in process, can be put on the market conveniently and quickly, can submerge to the deep seabed to finish submarine pipeline flaw detection tasks instead of men, and is high in efficiency and protects safety of personnel.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an underwater robot used for flaw detection of pipelines. The underwater robot is a small-scale, intelligent underwater vehicle capable of autonomous navigation underwater. It can discover and track pipelines, and can also detect whether the pipeline is damaged. Background technique [0002] Robot technology is an emerging intelligent manufacturing technology, which is widely used at home and abroad. The rise of DJI drones and Yunzhou smart unmanned ships illustrates this point. An autonomous underwater robot is a robot that can navigate autonomously at a depth of several meters or even thousands of meters or tens of thousands of meters below the water surface. It has the capabilities of autonomous navigation, autonomous navigation, and autonomous execution of underwater tasks. Compared with drones, unmanned vehicles and unmanned ships, the mission environment it is i...

AI Technical Summary

Problems solved by technology

The specific manifestations are as follows: 1) High-frequency radio waves cannot be used at a depth of more than ten meters underwater, which will make it difficult for the operator to maintain a good communication link with the underwater robot; and the use of underwater acoustic communicators is not only costly, but also has a high communication rate. 2) Any non-watertight electronic components, mechanical components, and propulsion components such as electronic components must be watertight and pressure-resistant, otherwise water seepage and water leakage will occur and normal underwater navigation will not be possible

[0003] At present, the existing technology is not capable of automatic detection of submarine oil and gas pipelines, and there is a lack of underwater robots that can complete the detection tasks of submarine pipelines.
