Abstract

The laser cleaning equipment comprises a drilling platform, a supporting column, a laser cleaning assembly, an annular driving assembly and a lifting adjusting assembly, the annular driving assembly is fixed to the bottom of the drilling platform and located outside the supporting column, and the lifting adjusting assembly is slidably connected into the annular driving assembly; the laser cleaning assembly is fixed to the bottom of the lifting adjusting assembly. According to the equipment, the surface of the supporting column is cleaned through laser, high-intensity light beams, short-pulse laser and a pollution layer interact, meanwhile, the optical fiber laser is fixed through the scanning galvanometer, surface cleaning is complete, the cleaning efficiency is high, the axial cone lens is installed in the laser, the light beams are converted into Bessel light beams, and the surface of the supporting column is cleaned through the Bessel light beams. And meanwhile, vertical annular adjustment can be conducted during laser cleaning, different side faces and different height positions of the supporting columns can be conveniently cleaned, and the cleaning efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of oil drilling platform cleaning, and in particular relates to a laser cleaning device and method for underwater drilling platform pillars. Background technique [0002] Drilling platforms are offshore structures primarily used for drilling wells. The platform is equipped with drilling, power, communication, navigation and other equipment, as well as safety life-saving and personnel living facilities, which is an indispensable means for offshore oil and gas exploration and development. [0003] Nowadays, the demand for oil and natural gas is increasing, and the number of offshore oil drilling platforms is also increasing. The pillars of oil drilling platforms are immersed in the sea for a long time and are eroded by seawater, resulting in a lot of rust on the surface. Therefore, it is necessary to clean the surface of the pillar frequently, but at present, it is generally pumped to the high-pressure jet ...
