Description

Technical Field

[0001] The utility model belongs to the technical field of deep-sea equipment, and in particular relates to a deep-sea floating ball. Background Art

[0002] Deep-sea platforms are important equipment for the exploration and development of deep-sea oil and gas resources. These platforms are usually moored in harsh marine environments for a long time by mooring systems, and are subjected to the combined effects of external loads such as wind, waves, and currents. During the operation of deep-sea platforms, a large number of optical, electrical, and oil cables are used to ensure the normal operation of the platform. Since the platform itself bears the load, in order to ensure the normal operation of the operating platform, the deep-sea cable needs zero buoyancy to ensure the safety of the platform and the stability of the cable, so deep-sea buoys are used to provide sufficient buoyancy.

[0003] Deep-sea buoys are materials that provide the required buoyancy for deep-sea operating equipment. Generally, deep-sea cables obtain buoyancy by bundling multiple floating units. During use, they have many shortcomings, such as unstable structure and easy vibration, high difficulty in overall assembly, and easy to fall off and fail under seawater erosion. Especially when the number of floating units increases, the risk of failure further increases.

[0004] Therefore, it is very necessary to develop a deep-sea buoy that is simple in structure, easy to use, can provide sufficient buoyancy for deep-sea cables, and has mechanical and chemical properties that meet deep-sea working conditions. Utility Model Content

[0012] In a preferred embodiment of the present invention, a collision prevention block is further arranged on one side of each semi-ellipsoid connecting the hinge, and the hinge is arranged on the collision prevention block to prevent the two semi-ellipsoids from colliding with each other.

[0013] In a preferred embodiment of the present invention, a lock and a lock groove are respectively provided on one side of the two semi-ellipsoids away from the hinge, and the lock groove is a trapezoidal groove.

[0014] In a preferred embodiment of the utility model, a V-shaped groove is provided at the hinge connection, and the float body can be opened and closed within the range of 0-90° to prevent damage caused by excessive force; when the float body is closed, the angle of the V-shaped groove is 90°, so that the hinge opening and closing point is closer to the central axis, reducing the force on the float body and preventing cracking.

[0015] In a preferred embodiment of the utility model, the float body is made of a lightweight pressure-resistant material, preferably a composite material of PVC foam, polyurethane foam and hollow glass microspheres; PVC foam and polyurethane foam are used for 0-1000mm underwater, and hollow glass microsphere composite materials are used for 600-10000m underwater.

[0016] In a preferred embodiment of the present invention, the fixing block and the pressure block are both made of polyurethane.

[0017] In a preferred embodiment of the present invention, the thickness of the first protective layer is 1-10 mm, and the thickness of the second protective layer is in the range of 0.1-0.3 mm.

[0018] In a preferred embodiment of the present invention, the first protective layer is a polyurea anti-collision coating to ensure that the buoy has certain mechanical properties to prevent damage during installation, while providing corrosion resistance to prevent erosion and damage in seawater.
