[0002] In subsea operations, it is often necessary to connect flexible risers or umbilicals between equipment on the seabed and vessels or fixed platforms on the surface. When the riser is connected to the underwater equipment, it needs to be pulled up to connect with the tubular fixed structure on the surface, and a bend protector is installed on the riser when connected to the fixed structure to protect the riser from bending fatigue caused by water flow and movement.

[0003] In the prior art, the flexible pipe and cable joint is connected to the platform through a bolt flange, and the installation and disassembly process is not easy to construct underwater, and the operation is complicated, time-consuming and labor-intensive.

[0004] The object of the present invention is to provide a system that does not require underwater operation or any external clamping devices to hold the buckle protector and riser in a fixed position during installation and to subsequently support the buckle protector to allow the riser to be fully pulled into place.

[0005] Therefore, a submarine cable connecting device that can be quickly disassembled and assembled is proposed. Summary of the invention

[0006] The object of the present invention is to provide a submarine cable connection device that can be quickly disassembled and assembled to solve the problem that the connection operation between the existing riser or umbilical cable and the ship or fixed platform on the water surface is complicated and requires an underwater installation flange structure.

[0008] Preferably, the quick-detach male head is designed as a T-sleeve, and the pull-in joint is designed as an inverted T-sleeve. The bottom end of the pull-in joint extends to the inner side of the quick-detach male head and is slidingly connected to the inner side surface of the quick-detach male head. The outer side bevel of the bottom end of the quick-detach male head is set, and the inner side bevel of the bottom end of the fixed sleeve female seat is set to match the outer side surface of the bottom end of the quick-detach male head.

[0009] Preferably, the clamping portion includes an L-shaped clamping block, a circle of placement grooves are evenly arranged on the outer side surface of the quick-release male head, the L-shaped clamping block is slidably arranged inside the placement groove, and a circle of shrinkage ring grooves connected end to end are arranged on the outer side surface of the bottom end of the pull-in joint corresponding to the inner end position of the L-shaped clamping block, the inner wall of the placement groove is provided with a shrinkage through groove that is connected to the inside of the shrinkage ring groove, and the inner end of the L-shaped clamping block penetrates the shrinkage through groove and extends to the inside of the shrinkage ring groove.

[0010] Preferably, a compression spring is installed on the inner wall of the placement groove by means of a screw, and the outer side surface of the compression spring is in compression contact with the inner side surface of the L-shaped clamping block. A limiting ring is horizontally arranged on the inner side of the fixed sleeve female seat, and the surface of the limiting ring is fixedly connected to the inner wall of the fixed sleeve female seat. The inner side surface of the limiting ring is in upward and downward sliding contact with the surface of the quick-release male head. When the inner inclined surface of the inner end of the fixed sleeve female seat is in contact with the outer inclined surface of the bottom end of the quick-release male head, the top surface of the limiting ring and the inner bottom surface of the placement groove are located in the same horizontal plane.

[0011] Preferably, the locking ring is horizontally sleeved on the outside of the L-shaped block, and the locking ring is connected to the outer side of the quick-release male head by screw two before assembly. When in use, the bottom surface of the limit ring and the locking ring are squeezed to generate shear force, cutting off screw two.

[0012] Preferably, the disassembly portion includes a disassembly ring, which is horizontally sleeved on the outside of the submarine cable, the bottom end face of the disassembly ring is an inclined surface, the top surface of the outer end of the L-shaped block is an inclined surface, and the inner side surface of the disassembly ring is adapted to the outer surface of the quick-detachable male head.

The installation, fixation and disassembly can be completed by simply pulling up or pressing down, which can greatly save the disassembly and assembly costs; 2. During installation, by pulling the connector upward, the quick-disassembly male head can be driven to move upward and insert into the fixed sleeve female seat. When the locking ring moves upward and contacts the limit ring structure of the fixed sleeve female seat, it is squeezed. Continue to pull the connector upward, and the bolts fixing the locking ring will be sheared and broken, causing the locking ring to fall off. Continue to pull the connector upward until the lower end surface of the L-shaped block is higher than the limit ring. The compression spring will pop the L-shaped block outward, and the L-shaped block contacts the top surface of the limit ring, thereby limiting the internal movable device from falling downward, completing the installation of the device. 3. When disassembling the submarine cable connection device, the disassembly ring is driven downward by pressing the paddle, so that the L-shaped block contracts inward under the pressure of the side wall of the disassembly ring, and the pressing spring is compressed. At this time, the joint is lowered and pulled in, and the L-shaped block and the quick-disassembly male head can be separated from the fixed sleeve female seat, thereby completing the disassembly of the submarine cable connection device; 4. When the disassembly part is not working, the lower end surface of the paddle contacts the inner wall of the upper end of the L-shaped through groove, the positioning groove of the paddle matches the limiting protrusion of the L-shaped through groove, and the locking bolt presses the paddle to fix the paddle.
