Abstract

The invention discloses an ocean mooring cable and anchor chain flaw detection inspection robot based on ocean temperature difference energy. The underwater inspection robot comprises an underwater inspection robot platform charging pile and a terminal. The underwater inspection robot is penetrated by the anchor chain and attached to the anchor chain to do reciprocating motion, and the inspection work of the underwater inspection robot is completed through real-time detection of the damage detector; the platform charging pile is installed on the side portion of the platform and makes contact with an anchor point of the anchor chain platform, and when the underwater inspection robot inspects to the sea surface, energy is supplemented through the platform charging pile; the terminal serves as a signal receiving end and is used for receiving and processing information detected by the underwater inspection robot. The ocean temperature difference energy is converted into the motion kinetic energy of the underwater inspection robot, so that the energy consumption in the anchor chain flaw detection process is reduced; meanwhile, through routing inspection of the anchor chain, the fracture risk caused by local damage of the anchor chain can be avoided; in addition, the reciprocating motion of the underwater inspection robot solves the problem of biological attachment corrosion of the ocean anchor chain, and the life cycle of the anchor chain is prolonged.
