Ocean equipment underwater test device and operation method thereof

Abstract

The invention relates to an underwater test device for marine equipment and an operation method thereof, the underwater test device comprises a steel structure frame, the four corners of the top of the steel structure frame are respectively and fixedly provided with an auxiliary suspension fitting, the four auxiliary suspension fittings are connected with photoelectric composite armored cables through composite cable bearing heads, and the ends of the photoelectric composite armored cables are simultaneously connected with a hoisting main suspension fitting; a connecting beam is arranged in the middle of the top face of the steel structure frame, an electric-hydraulic plug-in pressure-resistant tank and a mechanical arm are installed at the bottom of the connecting beam, parallel square pipes are welded to the bottom of the steel structure frame, a planking grid is laid on the square pipes, and an equipment testing tool is fixed to the upper surface of the planking grid. A tested object is placed on the upper surface of the equipment test tool, a manipulator and a hydraulic source are carried to realize underwater debugging and maintenance, a lighting device, a camera and a holder are carried to realize maximum collection of data and image data in a test process through a photoelectric composite cable and a bearing head, and the equipment test tool can better serve technical improvement and the like of tested marine equipment.

Description

technical field [0001] The invention relates to the technical field of deep-sea support equipment, in particular to an underwater test device for marine equipment and an operation method thereof. Background technique [0002] In recent years, with the vigorous development of marine resources development at home and abroad, my country's "deep-sea entry, deep-sea exploration, and deep-sea development" cannot be separated from the development of a series of new marine equipment. At present, the existing underwater test devices have single functions, high test costs, and high cost. The test effect is not intuitive, the integration of the test environment, test tools and the underwater autonomy of the test process have not yet been realized, which can not fully meet the development needs of new equipment.

Problems solved by technology

[0002] In recent years, with the vigorous development of marine resources development at home and abroad, my country's "deep-sea entry, deep-sea exploration, and deep-sea development" are inseparable from the development of a series of new marine equipment. Currently, the existing underwater test devices have single functions, high test costs, and The test effect is not intuitive, and the integration of the test environment, test tools and underwater autonomy of the test process have not yet been realized, which can no longer fully meet the development needs of new equipment

[0003] At present, the functions of the existing marine equipment test devices are relatively single, the test data is not intuitive, and the cause of the failure during the underwater test is not easy to troubleshoot; when it is necessary to carry out tests on multiple marine equipment, the test period is long and there is a phenomenon of waiting , while the rental of scientific research ships and other platforms is relatively expensive. If multiple marine equipment are tested simultaneously, the number of winches and A-frame configurations for shore-based or surface ships is high, and the test cost is also high, and it is easy to wind cables. The effective test time of the trial voyage is short, resulting in long cycle and high cost
