Description

Technical Field

[0001] The utility model relates to the technical field related to submarine cable laying, and in particular to a buoy structure and a submarine cable system for submarine cable laying. 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 cable laying process, the cable will be put into the water through the water tank by the cable laying machine, and inflatable inner tubes or floating balls will be placed at certain intervals to help the cable float. The cable head is tied with a steel rope net and connected to the traction wire of the traction equipment set at the landing point. Then the traction equipment is started to pull the cable into place. After the cable is in place, divers need to remove the inflatable inner tubes or floating balls on the surface one by one, so that the cable can slowly sink to the bottom of the water.

[0004] The buoys need to be tied and fixed on the submarine cable at certain intervals. This requires the installation workers to master the knot tying method to ensure that it is secure. Unskilled workers need to be trained and learn the tying method before taking up their posts, and the pre-job training time is long.

[0005] The shallow coastal section is affected by tides, wind and waves, and topography. Generally, the water flow rate is high or the waves are large. Divers need to overcome the complex and changeable underwater environment and poor visibility. There are also safety risks in cutting off the foam float underwater. At the same time, the underwater removal of the float is affected by the operating environment. It is also limited by the divers' physical strength and the number of dives. It cannot be operated continuously for a long time, so the operating efficiency is low;

[0006] After the divers release the buoys, they need to recover them one by one to the boat. The number of buoys recovered in a single trip is limited by the boat's loading capacity, and it takes multiple round trips between the site and the main operation boat to complete the recovery. If the buoys are not recovered in time, they will be washed away by the tide, resulting in the loss of the buoys.

[0007] At present, no effective solution has been proposed to address the problems in related technologies, such as long training time for knot tying methods, complicated knot untying with safety risks, and easy loss of the buoy. Utility Model Content
