Title:
RADIATION-RESISTANT LASER CLEANING DEVICE AND USE METHOD
Document Type and Number:
WIPO Patent Application WO/2022/148118
Kind Code:
A1
Abstract:
The present application provides a radiation-resistant laser cleaning device and a use method. The radiation-resistant laser cleaning device comprises a moving positioning mechanism, an entering mechanism, a cleaning mechanism, and a laser transmission mechanism; the laser transmission mechanism penetrates through the moving positioning mechanism and the entering mechanism in sequence, and the front end of the laser transmission mechanism is connected to the cleaning mechanism; the moving 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 cleaning mechanism, as a whole, enters a container to be cleaned; 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 till cleaning is finished. When performing field cleaning operation in a space having a high radiation dose rate, the laser cleaning device of the present application is low in failure rate, high in reliability and small in overall size, and can conveniently and directly enter fields for operation.
