Abstract

The invention discloses a test device for simulating laser cutting under the marine environment. The device comprises a pressurizing test box and a laser cutting device (4) located in the pressurizing test box. A drainage valve (6) is designed on the bottom face of the pressurizing test box. A liquidometer (11) and an observation window (10) are mounted on the outer surface of the first side face of the pressurizing test box, and a temperature sensor (9) and an underwater viewfinder lamp (12) are mounted on the inner surface of the first side face. A propeller (8) is mounted on the inner surface of the bottom face connected with the first side face and externally connected with a reducer (21) and a motor through a power input shaft (20). A monitoring camera (19) is mounted on the inner surface of the bottom face where the propeller is located. The test can seemingly simulate the marine environment of the position 50 m below the water surface, and effective test data are provided for the underwater laser cutting technology, so that laser parameter setting is optimized.

Description

technical field [0001] The invention relates to an underwater laser cutting test device for simulating marine environment parameters such as underwater pressure, flow field, temperature and salinity. Background technique [0002] At present, underwater laser cutting technology plays a vital role in the construction, maintenance and dismantling of offshore platforms, submarine pipelines, submarine oil storage depots, submarine tunnels and other marine engineering structures. Compared with traditional mechanical cutting methods, diamond saw cutting methods, abrasive jet cutting methods and other cutting methods, underwater laser cutting technology has the advantages of high efficiency, convenience, cost saving, safety and environmental protection. [0003] Research on underwater laser cutting technology at home and abroad is mostly experimental research, and the maximum water depth does not exceed 100mm. Laser cutting experiments and researches at a depth of 50m and above hav...
