Laser cleaning mechanism used for pipeline inner wall

Abstract

The invention discloses a laser cleaning mechanism used for the pipeline inner wall. The mechanism comprises a base, a focusing device, a rotating device and a reflection lens set; an inner cavity ofthe base is coupled with an optical fiber isolation device connected with a laser source, the focusing device is arranged at the front end of the base, the rotating device is arranged on the front endof the focusing device through a motor base, and the reflection lens set is fixedly connected with the rotating device. The focusing device comprises a focusing lens, the rotating device comprises adrive device and a rotating base, and the reflection lens set is arranged on the rotating base. According to the laser cleaning mechanism, a high-power pulse laser device transmits laser to the optical fiber isolation head through the transmission optical fibers, the pulse laser path passes through a hollow shaft of a stepping motor, the laser path is directly transmitted to the reflection lens placed at an angle of 55 degrees, the pulse laser path is changed, the high-power pulse laser is reflected and is incident to the pipeline inner wall required to be cleaned through a protection lens, amotor rotates to drive the laser path to rotate to finish the cleaning of the pipeline inner wall, and the mechanism is simple in structure, flexible and convenient to operate, and capable of effectively achieving the laser cleaning work of the pipeline inner wall.

Description

technical field [0001] The invention relates to the technical field of laser cleaning, in particular to a laser cleaning mechanism for the inner wall of a pipeline. Background technique [0002] Laser cleaning (Laser Cleaning) is an effective method to remove dirt particles and film layers of different materials and sizes on the solid surface. Laser cleaning is to use continuous or pulsed laser with high brightness and good directionality to form a laser beam with specific spot shape and energy distribution through optical focusing and spot shaping, and irradiate the contaminated material to be cleaned. After the pollutant material absorbs laser energy, it will produce a series of complex physical and chemical processes such as vibration, melting, burning, and even gasification, and finally make the pollutants detach from the surface of the material. Even if the laser acts on the cleaned surface, most of the They are all reflected and will not cause damage to the substrate,...

AI Technical Summary

Problems solved by technology

At present, most of the laser cleaning technology can only be used to clean the outer surface of the sample, and there are few laser cleaning technologies for laser cleaning the inner wall of the pipeline, which greatly limits the application range of laser cleaning.
