Angle offset compensation device for hard pipe system in deep sea mining with different water depth levels

Abstract

The invention discloses a hard pipe system angle offset compensation device for deep-sea mining with different water depth levels. The device includes a lower base, a linkage control oil cylinder, an upper base plate, and a pipe clamping mechanism; each oil cylinder is respectively equipped with displacement sensors, The pressure sensor, the displacement sensor and the pressure sensor are respectively used to measure the displacement and pressure of the corresponding oil cylinder in real time, and the electrical signals of the displacement sensor and the pressure sensor are output to the external servo system. The invention can be used to passively compensate the corresponding angle of the hard pipe system when the angle of the hard pipe system in deep-sea mining at different water depth levels is offset by factors such as sea waves and ocean currents, so as to avoid failure and damage of the hard pipe.

Description

technical field [0001] The invention relates to the field of deep-sea mining, in particular to an angle offset compensation device for a hard pipe system suitable for different water depth levels in deep-sea mining. Background technique [0002] As a complex system engineering, deep-sea mining engineering integrates a variety of technologies and equipment from multiple disciplines and fields. As an important part of the deep sea mining project, the surface support system involves many types of equipment. The hard pipe system is one of the important equipment involved in the surface support system. It is suspended under the mining vessel and deployed hundreds to thousands of meters underwater. It is used to connect underwater mining vehicles, hoses, relay stations and lift pumps, etc. The key component of the underwater equipment, its main function is to provide the slurry conveying channel, carry the deployment and recovery of the underwater equipment, and fix the umbilical...

AI Technical Summary

Problems solved by technology

However, in the actual mining process, the hard pipe system may deviate under the influence of sea waves, ocean currents and other factors, resulting in failure and damage of the hard pipe, which will adversely affect the entire mining project

[0003] At present, in terms of offshore oil drilling engineering, the existing pipeline angle offset compensation device is only suitable for a specific water depth, that is, when the hard pipeline is deployed to a certain depth, the device can correct the angle offset of the hard pipeline system. Compensation, unable to compensate for the angular offset of the hard pipe at different water depths
