An underwater ultrasonic flaw detection robot

Abstract

The invention discloses an underwater ultrasonic flaw detection robot, which comprises a frame module, an ultrasonic detection module, a rolling brush module, a pressure-resistant electronic cabin module, a motion module, an illumination module, a camera module, a floating body module and a counterweight module. Its frame module is not only easy to install, but also has a reasonable space layout to ensure the correct distribution and installation of other modules and the realization of its functions; its ultrasonic detection module has a large elastic domain, which is convenient for the robot to fit closely with the target object, and its structure is simple and easy to disassemble , which is convenient for the transportation of the robot and the protection of the flaw detection module. The ultrasonic probe structure on the front end has a certain degree of rotation, and can adapt to target structures with different inclination angles without changing the state of the robot body for ultrasonic detection; the rolling brush module is easy to operate and convenient. Surface cleaning of hull and underwater structures. The invention adopts an open-frame structure, and the space configuration is compact and reasonable, and has multiple functions such as roller brush cleaning, underwater camera, ultrasonic flaw detection, and the like.

Description

technical field [0001] The invention belongs to the technical field of unmanned underwater vehicles, in particular to an underwater ultrasonic flaw detection robot with cables used for underwater hulls and other underwater structures. [0002] technical background [0003] Building a maritime power is an important part of the cause of socialism with Chinese characteristics, and ships and underwater structures are an important part of building a marine power. Preventing accidents and ensuring the safety of marine construction facilities are crucial. Due to the complexity of the marine environment and numerous undercurrents, hull damage and seawater corrosion are inevitable during the service period of the ship. In order to obtain the degree of hull damage, the out-of-hull inspection has become an indispensable process. In traditional flaw detection operations, divers are usually required to operate. When operating in complex underwater environments, it is difficult to ensure w...
