[0028] Combine the following Figure 1-Figure 7 , through specific embodiments and application scenarios, a dynamic submarine cable joint release / installation system provided by an embodiment of the present invention is described in detail.

[0029] like Figure 1 As shown, the present invention provides a dynamic submarine cable joint release / installation system, comprising: a dynamic submarine cable joint 1, a connection seat 2, a bayonet 3, a driving mechanism 4, a fixing cylinder 5 and a self-locking mechanism 51 provided on the fixing cylinder 5. The fixing cylinder 5 is used to be installed on an offshore foundation platform. A locking block 11 and a sliding block 12 are slidably provided on the dynamic submarine cable joint 1. The locking block 11 is inserted into the connection seat 2. One end of the bayonet 3 is against the locking block 11, and the other end passes through the connection seat 2. The driving mechanism 4 is connected to the self-locking mechanism 51, and the connection seat 2 is provided with a locking groove 21.

[0030] like Figure 2 As shown, when the dynamic submarine cable joint 1 is in the released state, the slider 12 is retracted into the dynamic submarine cable joint 1, and the connecting seat 2 is locked in the fixing tube 5 by the self-locking mechanism 51. The bayonet 3 pushes the locking block 11 out of the connecting seat 2 under the resistance of the fixing tube 5, so that the dynamic submarine cable joint 1 and the connecting seat 2 are separated.

[0031] like Figure 3 As shown, when the dynamic submarine cable joint 1 is in the installed state, the slider 12 extends out of the dynamic submarine cable joint 1 and is inserted into the locking groove 21 , and the driving mechanism 4 drives the self-locking mechanism 51 to flip outward relative to the fixing tube 5 to release the connecting seat 2 .

[0032] It is understandable that if Figure 2 As shown, the connection seat 2 is cylindrical. Figure 4 As shown, in the initial state, the connection seat 2 is sleeved on the dynamic submarine cable, the dynamic submarine cable joint 1 is located inside the connection seat 2, and is preassembled with the connection seat 2 through the locking block 11. The connection seat 2 is provided with a groove 23. When the dynamic submarine cable joint 1 and the connection seat 2 are preassembled, the locking block 11 is inserted into the groove 23. Figure 4 As shown, the bayonet 3 is inserted into the connection seat 2. When the dynamic submarine cable joint 1 and the connection seat 2 are preassembled, one end of the bayonet 3 abuts against the locking block 11, and the other end extends out of the connection seat 2.

[0033] When the dynamic submarine cable joint 1 needs to be released, the dynamic submarine cable is pulled by the submarine cable pulling head to guide the connection seat 2 to pass through the bottom end of the fixing tube 5. When the connection seat 2 is inserted into the fixing tube 5, the self-locking mechanism 51 automatically locks the connection seat 2 in the fixing tube 5. Figure 2 As shown, under the squeezing of the fixing tube 5, the bayonet 3 retracts into the connection seat 2 to push the locking block 11 to be released from the connection seat 2. The connection seat 2 is locked in the fixing tube 5, and the dynamic submarine cable joint 1 is unlocked from the connection seat 2. The submarine cable pulling head continues to pull the dynamic submarine cable joint 1 out of the fixing tube 5, and the dynamic submarine cable joint 1 can be released from the dynamic submarine cable. At this time, the slider 12 is located inside the dynamic submarine cable joint 1 to avoid the connection seat 2.

[0034] like Figure 3 As shown, when the dynamic submarine cable joint 1 needs to be installed, the slider 12 is manually released so that the slider 12 extends out of the dynamic submarine cable joint 1. Then the dynamic submarine cable joint 1 passes through the top of the fixing tube 5, and the slider 12 moves down along the inner wall of the fixing tube 5 until it slides into the locking groove 21, thereby assembling the dynamic submarine cable joint 1 and the connecting seat 2 together.

[0035] like Figure 1 As shown, the driving mechanism 4 is installed on the outer wall of the fixing tube 5, and the driving end of the driving mechanism 4 is connected to the self-locking mechanism 51 to drive the self-locking mechanism 51 to flip outward relative to the fixing tube 5, thereby realizing the separation of the self-locking mechanism 51 and the connecting seat 2. At this time, the connecting seat 2 is disengaged from the fixing tube 5 under the action of natural gravity and the tension of the dynamic submarine cable, driving the dynamic submarine cable joint 1 to sink to the seabed together.

[0036] The present invention provides a dynamic submarine cable joint release / installation system, wherein a connection seat 2 is sleeved on a dynamic submarine cable, and a dynamic submarine cable joint 1 is preassembled through a locking block 11 and the connection seat 2. When the dynamic submarine cable joint 1 needs to be released from the dynamic submarine cable, the connection seat 2 is passed through the bottom end of a fixing tube 5, and the connection seat 2 is locked in the fixing tube 5 under the action of a self-locking mechanism 51. The bayonet 3 is pushed by the locking block 11 to be released from the connection seat 2 under the resistance of the fixing tube 5, thereby realizing the separation of the connection seat 2 and the dynamic submarine cable joint 1, and then the dynamic submarine cable joint 1 can be automatically released from the dynamic submarine cable; when it is necessary to install When the dynamic submarine cable joint 1 is assembled, the slider 12 is released to extend the slider 12 out of the dynamic submarine cable joint 1, and then the dynamic submarine cable joint 1 passes through the top of the fixing tube 5, and the slider 12 is locked in the locking groove 21, thereby realizing the automatic assembly of the dynamic submarine cable joint 1 and the connecting seat 2, and the driving mechanism 4 drives the self-locking mechanism 51 to flip outward relative to the fixing tube 5, so that the self-locking mechanism 51 and the connecting seat 2 are separated, and the dynamic submarine cable joint 1 automatically sinks to the seabed with the connecting seat 2, thereby realizing the rapid release and assembly of the dynamic submarine cable joint 1, without the need for manual underwater operations, avoiding the safety hazards of manual underwater operations, and shortening the construction time.

[0037] In some embodiments, Figure 5 As shown, the self-locking mechanism 51 includes a bolt block 511, a first elastic member and a fastening member. The fixing tube 5 is provided with a through hole. The bolt block 511 is installed in the through hole. One end of the first elastic member is fixed to the bolt block 511, and the other end is fixed to the fastening member. When the dynamic submarine cable joint 1 is in a released state, the fastening member and the connecting seat 2 are abutted.

[0038] Specifically, a through hole is provided on the side of the fixed cylinder 5. A bolt block 511 is installed at the through hole to provide support for the abutting member and the first elastic member. Optionally, the first elastic member is a spring. The spring is located between the abutting member and the bolt block 511. At least part of the abutting member protrudes out of the inner wall of the fixed cylinder 5. As the connecting seat 2 is inserted, the abutting member and the outer wall of the connecting seat 2 are tightly abutted, thereby locking the connecting seat 2 in the fixed cylinder 5.

[0039] Specifically, Figure 1 and Figure 5 As shown, the dynamic submarine cable joint release / installation system further includes a cam ring 6. The cam ring 6 is rotatably sleeved on the fixing tube 5. The cam ring 6 is provided with a support ear 61. The bolt block 511 is hinged to the outer side wall of the fixing tube 5, and the driving end of the driving mechanism 4 is connected to the cam ring 6. As the cam ring 6 rotates, the support ear 61 and the bolt block 511 collide to push the bolt block 511 to flip outward relative to the fixing tube 5, so that the abutting member and the connecting seat 2 are separated.

[0040] Optionally, the driving mechanism 4 can be an electric push rod. The electric push rod is fixed to the outer wall of the fixed cylinder 5. The telescopic end of the electric push rod is fixedly connected to the cam ring 6. In the initial state, the support ear 61 and the bolt block 511 are separated. When it is necessary to release the connecting seat 2 from the fixed cylinder 5, the telescopic end of the electric push rod is driven to extend forward to drive the cam ring 6 to rotate relative to the fixed cylinder 5. The support ear 61 rotates with the cam ring 6 until it contacts the bolt block 511, thereby pushing the bolt block 511 to be turned outward relative to the fixed cylinder 5, and the abutment moves outward with the bolt block 511 to release the connecting seat 2.

[0041] In some embodiments, multiple sets of self-locking mechanisms 51 are provided. The multiple sets of self-locking mechanisms 51 are arranged at intervals along the radial direction of the fixing tube 5 to further firmly lock the connecting seat 2 in the fixing tube 5.

[0042] Optional, such as Figure 6 As shown, the self-locking mechanism 51 is provided in three sets. The three sets of self-locking mechanisms 51 are evenly spaced along the radial direction of the fixed cylinder 5. In this embodiment, the cam ring 6 is provided with three lugs 61. When it is necessary to release the connecting seat 2 from the fixed cylinder 5, the driving mechanism 4 drives the cam ring 6 to rotate, and the three lugs 61 correspond to and contact the bolts of the three self-locking mechanisms 51 to push the three bolt blocks 511 to flip outward relative to the fixed cylinder 5 at the same time, thereby releasing the connecting seat 2.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the end of the bayonet 3 close to the fixing tube 5 has an end cap 31. The connection seat 2 is provided with a groove 22, and the notch of the groove 22 faces the fixing tube 5. The bayonet 3 passes through the bottom of the groove 22 and abuts against the locking block 11. When the dynamic submarine cable joint 1 is in the released state, the end cap 31 is received in the groove 22.

[0044] By providing an end cap 31 at one end of the bayonet 3 close to the fixing tube 5, the end cap 31 increases the contact area between the bayonet 3 and the inner wall of the fixing tube 5, ensuring that the bayonet 3 has sufficient thrust to push the locking block 11 out of the connection seat 2, so as to achieve rapid unlocking of the dynamic submarine cable joint 1. When the locking block 11 is disengaged from the connection seat 2, the end cap 31 is accommodated in the groove 22, so that the bayonet 3 can avoid the fixing tube 5 when the connection seat 2 sinks.

[0045] In some embodiments, Figure 1 As shown, one end of the fixing tube 5 is gradually expanded to guide the connection seat 2 to quickly penetrate into the fixing tube 5. At the same time, the large diameter end of the fixing tube 5 is used to guide the end cap 31 to retract into the groove 22 to increase the contact area between the inner wall of the fixing tube 5 and the end cap 31, ensuring that the bayonet 3 has sufficient thrust to push the locking block 11 out of the connection seat 2, so as to achieve rapid unlocking of the dynamic submarine cable joint 1. Optionally, as Figure 3 and Figure 4 As shown, a side surface of the end cap 31 close to the inner wall of the fixing tube 5 is arc-shaped so that the inner wall of the fixing tube 5 can be in close contact with the end cap 31 .

[0046] In some embodiments, Figure 2 As shown, the dynamic submarine cable joint release / installation system also includes a second elastic member 7. The dynamic submarine cable joint 1 is provided with a connection groove 13. The notch of the connection groove 13 faces the connection seat 2, and the locking block 11 is slidably arranged in the connection groove 13, so that the locking block 11 can be retracted into the interior of the dynamic submarine cable joint 1 under the push of the bayonet 3. The second elastic member 7 is arranged on one side wall of the connection groove 13 and abuts against the locking block 11, so that the locking block 11 is firmly clamped between the other side wall of the connection groove 13 and the second elastic member 7, ensuring that the locking block 11 can be stably fixed at the target position. For example, when the connection seat 2 and the dynamic submarine cable joint 1 are preassembled, the locking block 11 can be firmly inserted into the connection seat 2 by the elastic force of the second elastic member 7, preventing the locking block 11 from automatically retreating into the connection groove 13. When the dynamic submarine cable joint 1 is unlocked from the connection seat 2, the locking block 11 can be firmly locked in the connection groove 13 by the elastic force of the second elastic member 7, preventing the locking block 11 from automatically extending out of the connection groove 13.

[0047] In some embodiments, multiple sets of bayonet pins 3 and locking blocks 11 are provided as a set. Multiple sets of bayonet pins 3 and locking blocks 11 are arranged at intervals along the radial direction of the dynamic submarine cable joint 1 to ensure the stability of the pre-assembly of the connection seat 2 and the dynamic submarine cable joint 1; when the connection seat 2 is inserted into the fixing tube 5, multiple bayonet pins 3 push multiple locking blocks 11 simultaneously to enhance the unlocking force of the bayonet pins 3 on the dynamic submarine cable joint 1. Optionally, three sets of bayonet pins 3 and locking blocks 11 are provided as a set. Three sets of bayonet pins 3 and locking blocks 11 are evenly spaced along the radial direction of the fixing tube 5.

[0048] In some embodiments, Figure 2 As shown, the dynamic submarine cable joint release / installation system further includes a third elastic member 8, a spring pin 9 and a latch 10. The dynamic submarine cable joint 1 is provided with a mounting groove 14. The slider 12 is slidably arranged in the mounting groove 14. One end of the third elastic member 8 is fixed to the bottom of the mounting groove 14, and the other end is fixed to the slider 12. The spring pin 9 is arranged on a side wall of the mounting groove 14.

[0049] When the dynamic submarine cable joint 1 is in the released state, the spring pin 9 and the slider 12 are arranged to lock the slider 12 in the installation groove 14. When the dynamic submarine cable joint 1 is in the installed state, the latch 10 is inserted into the spring pin 9 to separate the spring pin 9 and the slider 12, and the slider 12 extends out of the installation groove 14.

[0050] Specifically, when the dynamic submarine cable joint 1 needs to be released, the spring pin 9 presses the slider 12 against the other side wall of the installation groove 14, so that the slider 12 is accommodated in the installation groove 14, thereby avoiding the connection seat 2. When the dynamic submarine cable joint 1 needs to be installed, the pin 10 is manually inserted into the spring pin 9 along the radial direction of the spring pin 9 to shrink the spring pin 9, thereby realizing the separation of the spring pin 9 and the slider 12. The slider 12 extends out of the installation groove 14 under the elastic action of the third elastic member 8. During installation, the dynamic submarine cable joint 1 is inserted into the connection seat 2, and the slider 12 moves along the inner wall of the connection seat 2 until the slider 12 slides into the locking groove 21, thereby realizing the automatic assembly of the dynamic submarine cable joint 1 and the connection seat 2.

[0051] In some embodiments, Figure 7 As shown, the third elastic member 8, the spring pin 9, the latch pin 10 and the slider 12 are provided in a plurality of sets. The plurality of sets of the third elastic member 8, the spring pin 9, the latch pin 10 and the slider 12 are arranged at intervals along the radial direction of the dynamic submarine cable joint 1, so as to further ensure the stability of the assembly of the dynamic submarine cable joint 1 and the connecting seat 2.

[0052] Optionally, the third elastic member 8 , the spring pin 9 , the latch pin 10 and the slider 12 are provided in three sets, and the three sets of the third elastic member 8 , the spring pin 9 , the latch pin 10 and the slider 12 are evenly spaced along the radial direction of the dynamic submarine cable joint 1 .

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
