Sea life cleaning robot Zhejiang University scientists developed a special oil drilling platform to clean the surface of the steel tube attached to the marine organisms, and in China's East China Sea Pinghu oil and gas field sea trial success.

So, how does this sea life cleaning robot actually work?

Climbing firmly on the pipe wall, spraying water full of bubbles, the accumulation of shells was a "sweep" and empty.

The water jet is a new design that produces a large number of cavitation bubbles by flowing water at high speeds through cavitation nozzles, which are then jetted onto the surface to be cleaned, collapsing and generating a micro-jet in a narrow area, removing surface adhesions.

According to China News Service, in the first sea trial, the cleaning speed of the sea life cleaning robot reached 21.7 square meters / hour, cleaning water pressure of 20 MPa, much lower than the artificial cleaning water pressure of 70 MPa, but can achieve the same cleaning effect. The robot adopts cavitation jet, conduit adaptive, visual navigation control and other technologies. Moreover, it comes with an adaptive permanent magnetic adsorption module, which can achieve stable adsorption on the surface of steel conduits of different diameters, as well as cross between pipes of different diameters.

According to Science and Technology Daily, the sealife cleaning robot improves the simplicity and maneuverability of marine operations, and is able to completely replace divers in underwater sealife cleaning work. The robot can be popularized and applied to ship cleaning, bridge cleaning and inspection in the future. In addition, because the robot is amphibious, the platform of other high-altitude dangerous work, such as painting, testing and other work, can also be handed over to the robot to complete.
