Radiation-resistant pipeline laser cleaning device and using method

Abstract

The invention provides a radiation-resistant pipeline laser cleaning device. The radiation-resistant pipeline laser cleaning device comprises a laser transmission mechanism, a fixed support, a movement mechanism, a guide dust collection device and a cleaning mechanism, wherein the emitting side of the laser transmission mechanism sequentially penetrates through the movement mechanism and the guide dust collection device and is connected with the cleaning mechanism; the guide dust collection device comprises a vacuum dust collection device, a guide wheel mechanism and a bolt, the guide wheel mechanism is arranged on the outer side of the vacuum dust collection device, and the bolt is used for fixing the guide wheel mechanism on the front end surface of the movement mechanism; and the cleaning mechanism comprises a beam expander, a plane mirror, a galvanometer unit and a focusing device which are arranged at an outlet of an optical fiber air pipe, and the plane mirror is arranged right ahead of the beam expander and is connected with the inner wall of the cleaning mechanism. According to the radiation-resistant pipeline laser cleaning device, the movement mechanism acts on the cleaning mechanism to rotate and feed at the same time, so that light beams focused on the inner wall of a pipeline to be cleaned do spiral motion, and the defect that the cleaning device cannot adapt to a cleaning environment with a high radiation dose rate is overcome; and a first supporting rod in a movement unit is hinged to the end surface between two supporting plates, so that good flexibility is achieved.

Description

technical field [0001] The present application relates to the technical field of pipeline inner wall cleaning, in particular to a radiation-resistant pipeline laser cleaning device and its use method. Background technique [0002] Pipelines are widely used in petroleum, natural gas transportation, agricultural irrigation, etc. There will be problems such as sludge and rust solidification in the pipelines for a long time, which will cause the pipe diameter to become smaller, which will affect the normal use of the pipelines. Therefore, the pipelines should be cleaned to make the pipelines It is very important to desilt and restore the surface of the material itself, which can ensure safety and prolong the service life. [0003] At present, the pipeline cleaning technology is divided into two categories: physical cleaning and chemical cleaning. Among them, the common high-pressure liquid flushing and mechanical cleaning two physical cleaning methods have poor cleaning effect o...
