Embodiment 1

[0041] Such as Figure 1-3 As shown, the application provides a radiation-resistant laser cleaning device, including a mobile positioning mechanism 1, an entry mechanism 2, a cleaning mechanism 3, and a laser transmission mechanism 4,

[0042] The laser transmission mechanism 4 runs through the moving positioning mechanism 1 and the entry mechanism 2 in turn, and is connected to the cleaning mechanism 3 at its front end;

[0043] The laser transmission mechanism 4 includes a fiber laser 41, a fiber gas tube 42, a beam expander 43, and a vibrating mirror 44. The fiber laser 41 transmits one side and the vibrating mirror 44 through the mobile positioning mechanism 1 and enters the interior of the mechanism 2 in sequence. The fiber optic gas tube 42 is connected, and the beam expander 43 is arranged in the fiber gas tube 42 and is close to the rear side of the vibrating mirror 44 .

[0044] The mobile positioning mechanism 1 includes a mobile platform 11, a hollow shaft motor 12...

Embodiment 2

[0063] The technical scheme of the present application has been described in detail above in conjunction with the accompanying drawings. Based on the same inventive concept, the present application also proposes a method for using a radiation-resistant laser cleaning device, which is implemented as described in any one of the above-mentioned radiation-resistant laser cleaning devices. The method of using the device during operation comprises the following steps:

[0064] S1. The cleaning mechanism 3 enters the container to be cleaned as a whole;

[0065] Move the mobile platform 11 close to the container to be cleaned, align the pipe thread 21 outside the mild steel skin 22 with the threaded hole of the container to be cleaned, turn on the hollow shaft motor 12 to drive the hollow shaft 14 and the mild steel skin 22 to rotate, and pass the mild steel skin 22 The pipe thread 21 on the outer wall will screw the entry mechanism 2 and the cleaning mechanism 3 into the container to...

Abstract

The application provides a radiation-resistant laser cleaning device and its use method, including: a mobile positioning mechanism, an entry mechanism, a cleaning mechanism, and a laser transmission mechanism. Mechanism connection; the above four mechanisms respectively include mobile platform, hollow shaft motor, bearing seat, hollow shaft; positioning mechanism, pipe thread, mild steel skin; field mirror, field mirror support plate, screw rod, guide rod and pneumatic Motor; fiber laser, fiber gas tube, beam expander, galvanometer. First, enter the container to be cleaned through the cleaning mechanism as a whole; then adjust the position of the cleaning mechanism; then adjust the angle of the cleaning mechanism; finally turn on the fiber laser to clean until the cleaning is completed. When the laser cleaning device of the present application performs on-site cleaning operations in a space with a high radiation dose rate, the failure rate is low, the reliability is high, the overall volume is small, and it is convenient to directly enter the on-site operation.

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 ...
