Efficient string type deep sea environment testing device

Abstract

The invention provides an efficient string type deep sea environment testing device. The efficient string type deep sea environment testing device is used for performing medium-and-long-term deep sea environment exposure tests in the 500-3,000 m deep sea water environment and can perform multi-form corrosion and aging tests of metal materials, so that the deep sea environment tests can be carried out more efficiently and more flexibly. The device comprises ropes, sample frames, a buoy and a bottom anchor block, wherein the sample frames are connected with the adjacent ropes to form a straight line, one end of the straight line is connected with the buoy, and the other end of the straight line is connected with the bottom anchor block through a releaser; the sample frames are made of titanium or titanium alloys, and samples for the tests are modularly mounted on the sample frames. The efficient string type deep sea environment testing device performs the tests at the 500-3,000 m seabed, the multiple sample frames are connected to form a string, the samples are modularly mounted on the sample frames, the distance between adjacent sample frames is flexibly adjusted according to the exposure depth required by the tests, different types of samples can be selected for the exposure tests at different depths in the same sea area simultaneously, marine operation time is shortened, and the marine operation intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of testing devices in the ocean, in particular to a high-efficiency serial deep-sea environmental testing device. Background technique [0002] The deep sea is rich in oil, gas and mineral resources. According to statistics, two-thirds of the world's existing oil and gas reserves come from the deep sea. At present, developed countries have begun to develop technologies and equipment for deep-sea oil and gas exploration at a depth of about 3,000 meters. China's offshore oil development is moving towards the deep sea. The South China Sea has very rich oil reserves, but 75% of them are located in the deep sea of ​​2000-3000 meters. Therefore, it is urgent to carry out the design and development of relevant deep-sea equipment. The service environment of deep-sea engineering equipment is in seawater thousands of meters deep. The materials of the equipment are not only eroded by seawater, but also by the static p...

Problems solved by technology

[0005] For the second type of deep-sea corrosion test device, the type and quantity of materials put in are limited. Generally, only a few kinds or more than a dozen samples can be put in at each depth, and the sample size is small; the sample frame of the device is only suitable for metal corrosion testing. test, other types of corrosion tests cannot be carried out

[0006] Although the above two test devices are suitable for the corrosion test of materials in deep sea water, they cannot meet the increasing demand for deep sea tests in terms of test efficiency and flexibility.
