Submarine cable underwater synchronous paying-off underwater vehicle

Abstract

The invention discloses a submarine cable underwater synchronous paying-off underwater vehicle which is characterized by comprising a shipborne mechanical system, a synchronous pushing system, a pneumatic launching system, a calculation center control system and a dragging and underwater-moving system. The technologies of electric automatization, aerodynamics, mechatronics and single chip microcomputer control and the like are integrated, underwater operation can be achieved, and the underwater vehicle is less affected by stormy waves; automatic detection and real-time paying-off can be achieved, the positioning precision is 0.5-3 m, the course accuracy is 0.01 degree, and a cable line corridor can be accurately controlled; cable laying is high in speed and can be controlled in real time, and the highest cable laying speed can reach 50 KM/h; the automation degree is high, and the number of construction staff is greatly decreased; the integration degree is high, and the whole process can be monitored; construction obstacles for the cable line corridor do not need to be cleared away, so that the environment is protected; all the systems can be recycled, and secondary investment is low; the systems operate synchronously, and the tension force of submarine cable laying is reduced; the line first-aid repair capability is high, and the submarine cable underwater synchronous paying-off underwater vehicle is suitable for line reconstruction work after seaquakes; and the structure is reasonable, and the performance is reliable.

Description

technical field [0001] The invention relates to the technical field of submarine cable laying, and relates to a submarine cable underwater synchronous release submersible. Background technique [0002] There are usually three types of power supply for coastal islands and mining platforms: diesel generators, spanning towers, and submarine cables. The capacity of generators is limited, which makes it difficult to meet large-scale power demand; the cost of erecting spanning towers is high, and windy and salty seaside areas are not suitable for tower operation; submarine cables have long life and mature technology, and are regarded as ideal power supply channels. In 2015, in the concept of "Global Energy Internet", intercontinental networking needs to cross the oceans such as Africa and Europe, Europe and North America, Australia and Asia, Asia and North America. The key to less. [0003] However, although submarine cables play a decisive role, their laying link is a major obs...

Problems solved by technology

[0003] However, although the submarine cable plays a pivotal role, its laying link is a major obstacle

The current submarine cable laying usually adopts the method of "walking and laying" by the cable laying ship. The whole process needs to accurately control the line corridor and the entry angle, which is not only slow, but also very difficult, and the construction often takes up a lot of manpower and material resources.

In addition, changing sea weather conditions often pose a huge threat to the project. Normal waves and strong winds will cause the cable laying ship to deviate from the track. , causing the submarine cable to deviate from the line corridor and even damage the submarine cable body. If it encounters strong winds at sea, the risk will increase sharply, which is very likely to lead to the failure of the entire project

Various deficiencies have greatly affected the development of submarine lines
