Underwater real-time surface dirt cleaning and detecting device for optical-fiber laser

Abstract

The invention relates to the field of cleaning, in particular to an underwater real-time surface dirt cleaning and detecting device for an optical-fiber laser, which is a cleaning device special for a sonar board of a submarine. The device provided by the invention comprises an underwater cleaning device, a power supply, a global positioning system (GPS) positioning device, a control device, an optical-fiber laser, a charge-coupled device (CCD) sensor, a first wireless signal device, a second wireless signal device, a computer, a power circuit and a control circuit. By using the device, real-time laser cleaning for the sonar board of the submarine on voyage is realized; and compared with the conventional cleaning method, the submarine does not need to be driven back to a dock, so that the cleaning cost and the cleaning time for the sonar board are reduced obviously. According to the device, the automation degree in the cleaning process of the sonar board of the submarine is high, and the labor intensity of operating personnel is reduced.

Description

[0001] Field [0002] The invention relates to the field of cleaning, in particular to a fiber laser underwater real-time cleaning surface dirt and a detection device, which is a cleaning device specially used for submarine sonar boards. technical background [0003] Laser cleaning technology is a process of using high-energy laser beams to irradiate workpieces to make the dirt, rust spots or layers on the surface evaporate or peel off instantly, so as to make the surface clean. Its mechanism is mainly based on the fact that after the pollutants on the surface of the object absorb the laser energy, they vaporize or expand when heated, so that the dirt is separated from the surface of the object, and then the purpose of cleaning is achieved. [0004] After the submarine sails for a period of time, there will be marine organisms on the surface of the hull, propeller, rudder and other underwater accessories (Liao Zhenfang, Chen Deshu, Deng Xiaogang, pulse cavitation jet cleaning ...

AI Technical Summary

Problems solved by technology

[0004] After the submarine sails for a period of time, there will be marine organisms on the surface of the hull, propeller, rudder and other underwater accessories (Liao Zhenfang, Chen Deshu, Deng Xiaogang, pulse cavitation jet cleaning the hull, cleaning the world, 2003, 19 (12) : 21-23), especially some key equipment, such as sonar board, due to the long-term reproduction of marine organisms, the sensitivity of signal reception is reduced, which in turn affects the normal military training process and effect

[0005] The current solution is that the submarine sails back to the dock at intervals of three months to clean the sonar panels manually, while the existing laser cleaning technology is typically such as the invention patent "portable laser cleaning system", application number "200610065407.8 ", limited by the conditions of use considered at the beginning of the design, it cannot be used to clean the sonar panels of submarines underway
