Description

Technical Field

[0001] The present invention relates to the technical field of submarine cable connection protection, and specifically to a submarine cable connection device that can be quickly disassembled and assembled. Background Art

[0002] In underwater operations, it is usually necessary to connect flexible risers or umbilical cables between equipment on the seabed and ships or fixed platforms on the water surface. When the riser is connected to underwater equipment, it needs to be pulled up to connect to a tubular fixed structure on the water surface, and a bending preventer is installed on the riser when it is connected to the fixed structure to protect the riser from bending fatigue caused by water flow and movement.

[0003] In the prior art, flexible pipe and cable joints are connected to the platform through bolt flanges. The installation and disassembly processes are not easy for underwater construction, and the operation is complex, time-consuming and laborious.

[0004] The object of the present invention is to provide a system that does not require underwater operation or any external clamping device to keep the bending preventer and the riser in a fixed position during the installation process, and then support the bending preventer to pull the riser completely into place.

[0005] Therefore, a submarine cable connection 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 a ship or fixed platform on the water surface is complex and requires an underwater installation flange structure.

[0007] To achieve the above object, the present invention provides the following technical solution: A submarine cable connection device that can be quickly disassembled and assembled, including a submarine cable;

[0008] And a fixed sleeve socket sleeved outside the submarine cable;

[0009] An insertion joint and a quick-disassembly male head are arranged inside the fixed sleeve socket from top to bottom, and both the insertion joint and the quick-disassembly male head are sleeved outside the submarine cable;

[0010] A disassembly mechanism is arranged inside the fixed sleeve socket corresponding to the upper part of the insertion joint, and an installation mechanism is arranged outside the quick-disassembly male head. The quick-disassembly male head is connected to the fixed sleeve socket by the installation mechanism;

[0011] The installation mechanism includes a clamping part and a locking ring;

[0012] The disassembly mechanism includes a limiting part and a disassembly part.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] Preferably, an L-shaped through groove is vertically penetrated through the front and rear surfaces of the fixed sleeve mother seat corresponding to the position of the disassembly ring, and a card-connecting through groove is penetrated through the front and rear surfaces of the disassembly ring. The inner wall of the fixed sleeve mother seat is slidably connected to the surface of the disassembly ring, and paddles are horizontally arranged on the front and rear sides of the fixed sleeve mother seat. The inner ends of the two paddles penetrate the corresponding L-shaped through grooves and extend into the corresponding card-connecting through grooves. During use, when the disassembly ring needs to be moved downward, first horizontally rotate the position of the paddle in the L-shaped through groove, and then press the paddle downward to drive the disassembly ring to move downward. The inner side surface of the disassembly ring squeezes the outer side surface of the L-shaped block, so that the L-shaped block moves toward the inside of the placement groove, and the pressure spring is compressed.

[0019] Preferably, the limiting part includes a locking bolt. A fixing block is fixedly arranged on the surface of the fixed sleeve socket corresponding to the upper part of the L-shaped through groove. A limiting protrusion is fixedly arranged on the inner wall of the upper end of the L-shaped through groove. A positioning groove is formed on the bottom surface of the dial. The inner wall of the positioning groove is adapted to the surface of the limiting protrusion. The locking bolt is threadedly arranged through the fixing block. When in use, before the dial rotates, loosen the locking bolt so that the bottom end of the locking bolt does not press against the top surface of the dial, and then lift the dial upward so that the bottom surface of the dial is higher than the limiting protrusion to complete the unlocking of the dial;

[0020] The number of L-shaped blocks can be adjusted according to the length and weight of the submarine cable, the weight of the anti-bending device, etc. to meet different shear stress requirements;

[0021] When the pressing spring is pressed down, it is necessary to ensure that the outer side surface of the L-shaped block enters the placement groove. At the same time, the pressing elastic force can eject the L-shaped block outward so that it can reach the top surface of the limiting ring and be stuck.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The quickly detachable submarine cable connection device,

[0023] 1. By setting the installation mechanism and the disassembly mechanism, the overall structure is convenient for disassembly and assembly, and no underwater operation is required. Only by pulling up or pressing down can the installation and fixation and disassembly be completed, which can greatly save the disassembly and assembly cost;

[0024] 2. During installation, by pulling up the pulling-in joint, the quick-release male head can be driven to move upward and insert into the fixed sleeve socket. When the locking ring moves upward to contact the limiting ring structure of the fixed sleeve socket, it is squeezed. Continuing to pull up the pulling-in joint, the bolt for fixing the locking ring will be sheared and broken, so that the locking ring falls off. Continuing to pull up the pulling-in joint until the lower end surface of the L-shaped block is higher than the limiting ring, the pressing spring will eject the L-shaped block outward, and the L-shaped block contacts the top surface of the limiting ring, thereby restricting the internal moving device from falling downward and completing the installation of the device;

[0025] 3. When disassembling the submarine cable connection device, by pressing down the dial to drive the disassembly ring to move downward, the L-shaped block contracts inward under the side wall pressure of the disassembly ring, and at the same time the pressing spring is compressed. At this time, lower the pulling-in joint, and the L-shaped block and the quick-release male head can be separated from the fixed sleeve socket, thereby completing the disassembly of the submarine cable connection device;

[0026] 4. When the disassembly part is not working, the lower end surface of the dial contacts the inner wall of the upper end of the L-shaped through groove. The positioning groove of the dial matches the limiting protrusion of the L-shaped through groove. At the same time, the locking bolt presses the dial to fix the dial.

An installation mechanism 7 is provided on the outer side of the quick-disassembly male head 3. The quick-disassembly male head 3 is connected to the fixed sleeve female seat 2 by means of the installation mechanism 7.

[0042] The quick-disassembly male head 3 is designed as a T-shaped sleeve, and the pulling-in joint 4 is designed as an inverted T-shaped sleeve. The bottom end of the pulling-in joint 4 extends to the inside of the quick-disassembly male head 3 and is slidably connected to the inner side surface of the quick-disassembly male head 3. The outer side surface of the bottom end of the quick-disassembly male head 3 is provided with an inclined surface, and the inner side surface of the bottom end of the fixed sleeve female seat 2 is provided with an inclined surface that is adapted to the outer side surface of the bottom end of the quick-disassembly male head 3.

[0044] The clamping portion includes an L-shaped clamping block 71. A circle of placement grooves 72 is evenly formed on the outer side surface of the quick-disassembly male head 3. The L-shaped clamping block 71 is slidably arranged inside the placement grooves 72. A circle of shrinkage ring grooves 75 that are connected end to end is formed on the outer side surface of the bottom end of the pulling-in joint 4 corresponding to the inner end position of the L-shaped clamping block 71. A shrinkage through groove 74 is formed on the inner wall of the placement grooves 72 and is communicated with the inside of the shrinkage ring grooves 75.
