Abstract

The invention provides a radiation-resistant laser cleaning device and a using method. The radiation-resistant laser cleaning device comprises a movable positioning mechanism, an entering mechanism, a cleaning mechanism and a laser transmission mechanism, the laser transmission mechanism sequentially penetrates through the movable positioning mechanism and the entering mechanism, the front end of the laser transmission mechanism is connected with the cleaning mechanism, wherein the movable positioning mechanism comprises a moving platform, a hollow shaft motor, a bearing seat and a hollow shaft, the entering mechanism comprises a positioning mechanism, a pipe thread and a soft steel skin, the cleaning mechanism comprises a field lens, a field lens supporting plate, a screw rod, a guide rod and a pneumatic motor, and the laser transmission mechanism comprises an optical fiber laser, an optical fiber air pipe, a beam expander and a galvanometer. Firstly, the whole body enters a to-be-cleaned container through the cleaning mechanism; then the position of the cleaning mechanism is adjusted; then the angle of the cleaning mechanism is adjusted; and finally the optical fiber laser is started for cleaning until cleaning is finished. The laser cleaning device is low in failure rate, high in reliability and small in overall size and can conveniently directly enter the field for operation when carrying out field cleaning operation in a high-radiation-dose-rate space.

Description

technical field [0001] The present application relates to the field of laser cleaning, in particular, to a radiation-resistant laser cleaning device and a method of use. Background technique [0002] At present, laser cleaning, as a new cleaning method, has received extensive attention in recent years. Compared with traditional chemical cleaning and mechanical cleaning, laser cleaning has the advantages of non-contact, no thermal effect, wide application range, and no environmental pollution, so it has been widely used. The existing laser cleaning technology mainly adopts the form of machine tools, that is, the laser cleaning head is installed on the machine tool, and the workpiece to be cleaned is transported to the machine tool for cleaning. Only a small number of cleaning heads can realize on-site cleaning operations. [0003] And in the prior art, there are following problems at present: 1), the laser cleaning device that is used for spot cleaning has a large amount of ...
