Embodiment 1

[0058] A radiation-resistant laser cleaning irradiation device based on a pneumatic rotary motor, including a pneumatic galvanometer assembly 1, a collimator assembly 3, a flat field lens assembly 4, and a housing assembly 2 that seals the laser light path, wherein:

[0059] The pneumatic vibrating mirror assembly 1 includes a pneumatic rotary motor, a crank connecting rod driven by the pneumatic rotary motor, a rocker driven by the crank connecting rod to swing, and a rocker fixed on the swing shaft of the rocker to swing with it. The oscillating mirror, wherein the pneumatic rotary motor is driven by the compressed air fed into the intake pipe 7, and the exhaust gas is discharged from the exhaust gas discharge pipe. The flat field mirrors of the mirror assembly 4 are aligned to reflect the laser beam.

[0060] In radioactive decontamination operations, laser cleaning generally only requires the oscillating mirror to vibrate at a fixed amplitude, and the oscillating motion of...

Embodiment 2

[0074] In order to ensure the sealing of the laser light path, the housing assembly includes a motor base 201 and a housing 202 fixed on the motor base 201, and an assembly hole for assembling the pneumatic rotary motor is formed on the motor base 201 , the center of the one-piece rocker 104 is rotatably connected to the motor base 201 through the rocker bearing 110, and a space for accommodating the vibrating mirror is formed in the housing 202, and the adjacent two side walls of the housing 202 A mounting hole 204 for a collimator and a mounting hole 205 for a flat field lens are respectively formed for the laser light path to pass through.

[0075] The laser light collimated by the collimator assembly 3 enters the casing 202 through the collimator mounting hole 204, is reflected by the galvanometer lens 105, passes through the casing 202 through the flat field lens mounting hole 205, and finally passes through the flat field lens assembly 4 focus.

[0076] As a preferred m...

Embodiment 3

[0078] In order to ensure a good collimation effect, the collimator assembly 3 includes a collimator housing 301, a collimator mirror 302 installed in one end of the collimator housing, and a collimator mirror 302 installed in the other end of the collimator housing 301. Fiber 304 .

[0079] The collimator housing 301 is a cylindrical structure with one end sealed (not a seal, with a small hole for installing an optical fiber) and one end opened, the collimator mirror 302 is assembled at one end of the opening, and the optical fiber 304 is installed at one end of the seal, and The ends of the optical fibers 304 are located within the cylindrical structure.

[0080] There is a small amount of scattering of the laser in the collimator and is absorbed by the collimator, which will cause the collimator to heat up when used for a long time. Therefore, in order to speed up the heat dissipation of the collimator, the outer surface of the collimator housing 301 is Radiating fins 303 ...

Description

technical field [0001] The invention relates to the technical field of laser micromachining, in particular to a radiation-resistant laser cleaning irradiation tool based on a pneumatic rotary motor. Background technique [0002] Laser cleaning is an emerging cleaning method in recent years. It has the characteristics of no need for cleaning media and no incremental secondary pollution. It is very suitable for application in the nuclear industry. It can be used in the process of radioactively contaminated components and decommissioning of nuclear facilities. Directly strip the contaminated nuclides on the surface and collect them through vacuum equipment, effectively preventing the spread of nuclear pollution, reducing secondary pollution and reducing post-processing costs. [0003] The laser cleaning machine uses a pulse laser to generate pulsed laser light, which is transmitted to the laser cleaning execution device by an optical fiber. It is generally called a laser irradi...
