The world’s first “gecko robot” passed the test application in the “Hualong No. 1” nuclear power unit – Passionategeekz

Passionategeekz June 20th news, Comprehensive Science and Technology Daily and Guangming Daily today, the world’s firstFour-legged heat transfer tube detection robotThe “Hualong No. 1” unit successfully passed the engineering application test.

This robot developed by Harbin Engineering University in conjunction with multiple unitsLike a tigressadopts a unique four-leg anchor claw structure, efficient motion planning and visual positioning technology, which can crawl while detecting, greatly shortening the movement time during the detection process.

The heat transfer pipe of the evaporator of the nuclear power plant is the “orta” of nuclear energy safety. If the fatigue, defects and corrosion of the heat transfer pipe are not discovered in time, it may rupture and cause a nuclear leakage accident.

Compared with traditional inspection robots, the inspection coverage rate of four-leg heat transfer tube inspection robots has been greatly improved, which not only reduces construction periods, but also reduces maintenance costs. Provides a new solution for the intelligent operation and maintenance of nuclear power steam generators.

At present, this achievement has been successfully applied in the nuclear power unit of China General Nuclear Corporation.It can cover various stack types such as Hualong No. 1, which is 200% more efficient than traditional heat transfer tube detection robots.achieving full coverage of heat transfer pipe detection, greatly reducing the reactor overhaul period and maintenance costs.
