A laser descaling device and method using liquid core optical fiber

Abstract

The invention provides a laser descaling device using a liquid core optical fiber, a support mechanism (1), an optical fiber tube shrinkage mechanism (2), a liquid core filling mechanism (3), a steering mechanism (4), and a focus cleaning mechanism (5) , characterized in that: the supporting mechanism (1) includes a track bracket (1.2), one end of the reel (2.2) of the optical fiber tube shrinking mechanism is connected to the hydraulic motor (2.1), and the other end is connected to the reel (2.3); The liquid core filling mechanism (3) includes a liquid core delivery system (3.1), and the liquid enters the liquid bag in the flexible optical fiber tube (4.1) through the liquid penetrating piece (3.2) and the input pipe (3.3); the said steering mechanism (4) is a flexible optical fiber tube (4.1); the focus cleaning mechanism (5) includes a laser generator (5.1), and the laser beam of the laser generator (5.1) can reach the predetermined descaling after passing through the flexible optical fiber tube (4.1). Location. In the anti-radiation flexible laser cleaning device of the present invention, when the flexible optical fiber tube is not in use, the reel can be driven by a hydraulic motor to roll up, so it occupies a small volume, is convenient to work on site, and has low failure rate and high reliability.

Description

technical field [0001] The invention relates to the field of laser cleaning, in particular to a laser descaling device and method using a liquid-core optical fiber. Background technique [0002] Compared with other cleaning methods, laser cleaning has the advantages of high cleanliness, precision and controllability, no pollution, only power supply, and simple operation. The ordinary optical fiber will inevitably lose part of the energy in the process of conducting energy. At the same time, the inside of the liquid-core optical fiber is a free-flowing liquid, and the outer layer is a flexible plastic hose. When the liquid-core optical fiber is bent, the outer layer When the hose is bent, the internal liquid flows, which makes the liquid core optical fiber have good flexibility. The inside of the traditional optical fiber bundle is a fiber monofilament made of hard glass or quartz material. When the optical fiber bundle is bent sharply or frequently, these fiber filaments ar...

AI Technical Summary

Problems solved by technology

The inside of the traditional optical fiber bundle is a fiber single filament made of hard glass or quartz material. When the optical fiber bundle is bent severely or frequently bent, these fiber filaments are likely to be broken, resulting in dead pixels and dark spots. spots, leading to a decrease in light transmission efficiency, and even damage to the entire fiber bundle

[0003] However, in the prior art, there are currently the following problems: closed operations are required for cleaning operations in high-radiation spaces, so the laser cleaning device must enter the site as a whole, and the space for cleaning the site is limited. Entering the construction site, even if the construction space is limited, it is inconvenient to carry out work
