Description

Technical Field

[0001] The utility model relates to the technical field of dynamic cable connection, and particularly relates to an underwater connection device for a dynamic cable. Background Art

[0002] With the further increase of energy demand, offshore wind power is gradually developing towards the deep and far sea, and the adoption of floating wind turbines has become the mainstream development direction. With the development of offshore oil and gas resources, the floating production system for deep and far sea oil and gas resources has also developed rapidly, and a large number of ship-shaped floating structures are used for deep and far sea oil and gas development. The deep and far sea environment is usually relatively harsh, and under the combined action of wind, waves and currents, the floating body platform will have a very large offset. Floating facilities are all connected to the land base through dynamic cables. The existing dynamic cable line types mainly press the cable body into an "S" or "W" line type by installing buoyancy blocks or counterweight blocks at different positions of the cable to adapt to the large-scale offset of the floating platform, and at the same time relieve the axial tension on the submarine cable body and ensure the minimum bending radius.

[0003] However, due to the more severe sea conditions in the shallow water area with a water depth of 50 meters and the obvious tidal range, the dynamic cable often drifts widely under the action of waves and ocean currents. And the ship activities are frequent in such water depth areas. The dynamic cable is installed underwater, and it is difficult for the navigating crew to clearly see the position of the dynamic cable in advance, especially at night when the visibility is extremely poor and the risk is greater. Therefore, the protection of the underwater line shape is extremely critical, especially the bent parts. Content of the Utility Model

[0004] The purpose of the utility model is to provide an underwater connection device for a dynamic cable.

[0005] The utility model provides the following technical solutions:

[0006] The utility model provides an underwater connection device for a dynamic cable, which includes a flexible protective sleeve wrapped outside the dynamic cable and a pair of horn-shaped opening members with opposite openings, and a protective straight pipe is communicated between the horn-shaped opening members; the flexible protective sleeve penetrates through the horn-shaped opening members and the protective straight pipe, and connection lugs required for seabed anchoring are arranged on the outer wall of the protective straight pipe.

[0007] Furthermore, a plurality of sacrificial anodes are arranged on the outer wall of the protective straight pipe.

[0008] Furthermore, the horn-shaped opening member includes a pair of opening half-watts that can be spliced into a horn shape, and a first flange half-ring for connecting with the protective straight pipe is arranged at the end of the opening half-watt.

[0009] Furthermore, arc-shaped connecting flanges along the side edges of the opening half-watt are arranged on both sides of the opening half-watt.

[0010] Further, the protective straight pipe includes a pair of straight pipe half tiles that can be spliced into a cylindrical shape.

[0011] Further, both ends of the straight pipe half tile are provided with second flange half rings for connecting to the flared opening parts.

[0015] Compared with the prior art, in the utility model, a flexible protective sleeve is wrapped around the dynamic cable at the installation connection point, then the tightening strap is tightened, and the protective straight pipe is used to restrain the flexible protective sleeve, so that the dynamic cable is firmly fixed. Both sides of the protective straight pipe are a pair of flared opening parts with opposite openings. The flared opening form can effectively fit when the dynamic cable bends, limit the overbending of the cable and will not wear the outer part of the cable. Through such a fixing form, the underwater linear shape of the dynamic cable is stably maintained, the connection with the anchoring point on the seabed is ensured to be reliable, and a continuous and stable connection is provided. The connection device is convenient to manufacture, convenient to repair and replace, and stable and reliable in long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
