Description

Technical Field

[0001] The utility model relates to the technical field related to submarine cable laying, and in particular to an auxiliary device for submarine cable transshipment. Background Art

[0002] Submarine cables are cables wrapped in insulating materials, laid on the seabed, and used for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, which are expensive but highly confidential. Submarine power cables are mainly used to transmit high-power electrical energy underwater, and have the same function as underground power cables, except that they are used in different occasions and laid in different ways. Since submarine cable projects are recognized by countries around the world as complex and difficult large-scale projects, complex technologies are used in environmental detection, marine physical surveys, and cable design, manufacturing, and installation. Therefore, there are only a few submarine cable manufacturers in the world, mainly in Norway, Denmark, Japan, Canada, the United States, Britain, France, Italy, etc. These countries provide laying technology in addition to manufacturing.

[0003] During the submarine cable laying construction, the submarine cable will be transported to the laying ship by crane at the dock to complete the cable connection, and then transported to the designated sea area by the ship for laying operations. At present, submarine cable laying ships are generally not equipped with offshore cable connection devices. Generally, two laying ships are close to each other and then transported by the transport guide wheel. When there is a change in position, the position of the guide wheel needs to be moved back and forth, making the transmission effect of the submarine cable between the two laying ships unsatisfactory.

[0004] Currently, no effective solution has been proposed for the problem in the related technology that the transmission effect of submarine cables between ships is not ideal and the position of the guide wheel needs to be moved back and forth. Utility Model Content
