Laser descaling device and method adopting liquid core optical fiber

Abstract

The invention provides a laser descaling device adopting a liquid core optical fiber. The laser descaling device comprises a supporting mechanism (1), an optical fiber tube shrinking mechanism (2), a liquid core filling mechanism (3), a steering mechanism (4) and a focusing cleaning mechanism (5), and is characterized in that the supporting mechanism (1) comprises a rail bracket (1.2), one end of a reel (2.2) of the optical fiber tube shrinking mechanism is connected with a hydraulic motor (2.1), and the other end of the reel (2.2) is connected with a winding drum (2.3); the liquid core filling mechanism (3) comprises a liquid core conveying system (3.1), and liquid enters a liquid bag in a flexible optical fiber tube (4.1) through a liquid penetrating piece (3.2) and an input pipeline (3.3); the steering mechanism (4) is the flexible optical fiber tube (4.1); and the focusing cleaning mechanism (5) comprises a laser generator (5.1), and laser of the laser generator (5.1) can reach a preset descaling position after passing through the flexible optical fiber tube (4.1). According to the anti-radiation flexible laser cleaning device, when the flexible optical fiber tube is not used, the winding drum can be driven by the hydraulic motor to wind, and therefore the occupied size is small, a site can be conveniently entered for work, the failure rate is low, and the reliability is high.

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
