Description

Technical Field

[0001] The present invention relates to the technical field of submarine cable equipment, in particular to a device for quickly releasing a dynamic submarine cable that isolates marine organisms from adhering to it. Background Art

[0002] Currently, most of the floating wind turbine power generation projects piloted in China still use the fixed wind turbine design concept, with the cable-to-turbine connection being a permanent, fixed connection. Floating wind farms operate in harsh environments, and during installation, divers must dive underwater to install and remove dozens of flange bolts, creating significant inconvenience. Furthermore, during operation, the cables and floating wind turbines are subject to potential accidents and malfunctions, and disassembling the cable-turbine connection requires inconvenience from divers diving underwater.

[0003] There are a few similar quick-release devices in use both domestically and internationally. While these devices eliminate the need for divers to operate underwater, they present numerous technical challenges that are difficult to overcome. The devices' mechanical structures are complex and bulky, with numerous electronic control drive units, such as hydraulic drives, and densely distributed sensors. This places a significant burden on the equipment's operational reliability and maintenance. Furthermore, these devices lack structural design considerations for preventing marine biofouling and rely solely on existing antifouling coating technology.

[0004] There are currently two connection methods used in China. One is the traditional bolt flange fastening connection method, which requires divers to dive underwater for manual installation. Underwater operations have high safety risks, long working hours, and high costs. The other is the use of underwater multi-cylinder driven or variable-position submarine cable release devices with complex structures. There are many electric drive units, and the structural design does not consider the problem of preventing marine organisms from attaching. It only uses unilateral anti-fouling coatings, and the coating lifespan is less than two years, resulting in a short service life of the equipment, high manufacturing costs, and limited market application promotion. Summary of the Invention

[0005] The present invention provides a dynamic submarine cable quick release device for isolating marine organism attachment, which is used to solve the technical defects in the above-mentioned prior art, shorten the construction time in the marine environment, improve work efficiency, save construction costs, and eliminate the need for divers to dive underwater for operations, thereby reducing the safety risks of personnel operations; at the same time, it effectively enhances the equipment's ability to resist marine organism attachment, thereby increasing the equipment's underwater service life and stability and reliability.

[0011] According to the present invention, a dynamic submarine cable quick release device for isolating marine organism attachment is provided. The elastic pin locking mechanism includes a driving shaft and an internal elastic pin. A first mounting groove is formed on the outer wall of the traction component. The internal elastic pin is installed in the first mounting groove. The male plug has a first through hole corresponding to the first mounting groove. The driving shaft is limitedly inserted into the first through hole. When the elastic pin locking mechanism is in the first locking state, the internal elastic pin abuts against the pushing shaft, and a portion of the internal elastic pin penetrates into the first through hole; When the elastic pin locking mechanism is in the second unlocking state, the internal elastic pin is separated from the pushing shaft, and the internal elastic pin is accommodated in the first mounting groove.

[0012] According to a dynamic submarine cable quick release device for isolating marine organism attachment provided by the present invention, the end of the pushing shaft away from the axial direction of the traction component is arranged in an arc shape, and the plug interface of the female plug is arranged in a trumpet shape. When the elastic pin locking mechanism is transformed from the first locking state to the second unlocking state, the pushing shaft abuts and squeezes the plug interface through the arc-shaped end, so that the pushing shaft compresses the internal elastic pin, so that the internal elastic pin is completely accommodated in the first installation groove.

[0016] The present invention provides a quick-release device for isolating marine organisms from attaching dynamic submarine cables. This device achieves rapid, automatic connection between a male and female plug through the synergistic action of an automatic installation release mechanism and a spring-loaded locking mechanism.

The entire installation process can be completed with the assistance of an ROV, eliminating the need for divers to manually operate bolts, significantly shortening construction time, improving efficiency, and eliminating safety risks associated with underwater operations. Furthermore, the automatic installation release mechanism utilizes a closed structure to effectively prevent marine organisms from entering the internal space.

[0031] The following combination Figures 1 to 7 The dynamic submarine cable quick release device for isolating marine organism attachment provided by the embodiment of the present invention is described in detail through specific embodiments and application scenarios.

[0032] In the embodiment of the present invention, Figure 1As shown, a device 10 for quickly releasing a dynamic submarine cable for isolating marine organism attachment includes a female plug 100, a male plug 200, a traction component 300, an automatic installation and release mechanism 400, and a spring-loaded locking mechanism 500. The female plug 100 is fixed to an offshore floating foundation platform. The female plug 100 has a plug-in barrel 110 with open ends. The male plug 200 is plugged into the plug-in barrel 110. The male plug 200 has a through hole 210 along its own axial direction. The traction component 300 is inserted into the through hole 210 and is movably connected to the male plug 200. The tail end of the traction component 300 is connected to the submarine cable 20. The automatic installation and release mechanism 400 is arranged around the outer circumference of the plug cylinder 110, and is used to limit the movable position of the male plug 200 and the female plug 100. The automatic installation and release mechanism 400 is arranged in a closed structure; the elastic pin locking mechanism 500 is connected between the male plug 200 and the traction component 300. The elastic pin locking mechanism 500 has a first locking state for locking the male plug 200 and the traction component 300 in advance, and a second unlocking state for unlocking the male plug 200 and the traction component 300 after the male plug 200 and the female plug 100 are locked.

[0033] The female plug 100 is the fixed component of the entire device, secured to the floating offshore platform, providing support and positioning. The female plug 100 includes a socket 110, open at both ends, for receiving and accommodating the male plug 200. This attachment to the platform ensures the stability of the entire device in the marine environment.

[0034] The male plug 200 is the movable component that mates with the female plug 100. It has a through hole 210 along its axis for accommodating the pulling member 300. The male plug 200 connects and disconnects quickly by plugging into the female plug 100. The male plug 200 is connected to the female plug 100 by inserting into the female plug 100's insertion barrel 110.

[0035] The pulling member 300 is inserted into the through hole 210 of the male plug 200 and is movably connected to the male plug 200. Its tail end is connected to the submarine cable 20. The function of the pulling member 300 is to transfer the tension of the submarine cable 20 to the male plug 200 and to achieve quick release when needed.

[0036] The automatic installation and release mechanism 400 is arranged around the outer circumference of the plug barrel 110, and is used to limit the movement of the male plug 200 and the female plug 100. The mechanism is arranged in a closed structure, which effectively prevents marine organisms from entering the internal space.

[0037] The automatic installation release mechanism 400 ensures that the male plug 200 is correctly positioned to prevent connection failure caused by position deviation. The mechanical action achieves quick release without manual operation, thereby improving operating efficiency.

[0038] The closed structure design effectively prevents marine organisms from entering the internal space, improving the equipment's ability to resist marine organism attachment.

[0039] The spring-loaded locking mechanism 500 is connected between the male plug 200 and the pulling component 300 and has two states: First locking state: Before the male plug 200 and the pulling component 300 reach the female plug 100, the spring-pin locking mechanism 500 locks the two together to ensure that the two are integrated, which is convenient for ROV operation.

[0040] Second unlocked state: when the male plug 200 is inserted into the female plug 100 and reaches a predetermined position, the spring-pin locking mechanism 500 is unlocked, releasing the pulling component 300 .

[0041] The first locked state ensures that the male plug 200 and the traction member 300 remain integrated before reaching the female plug 100, facilitating ROV operation. The second unlocked state allows the traction member 300 to be quickly released after the male plug 200 is correctly positioned, simplifying the operation steps and improving connection efficiency.

[0042] This application achieves rapid, automatic connection between the male plug 200 and the female plug 100 through the synergistic effect of an automatic installation and release mechanism 400 and a spring-loaded locking mechanism 500. Prior to reaching the female plug 100, the male plug 200 and the pulling member 300 are locked in a first state by the spring-loaded locking mechanism 500, ensuring their integration and facilitating ROV operation. When the male plug 200 is inserted into the insertion barrel 110 of the female plug 100 and reaches the predetermined position, the automatic installation and release mechanism 400 engages the locking mechanism to ensure the male plug 200 is properly seated. The entire installation process can be completed with the assistance of an ROV, eliminating the need for divers to manually operate bolts, significantly reducing installation time, improving efficiency, and eliminating safety risks associated with underwater operations. Furthermore, the automatic installation and release mechanism 400 utilizes a closed structure, effectively preventing marine organisms from entering the internal space. This isolates marine organisms from contact with key moving components within the mechanism (such as the movable components of the locking mechanism), preventing their attachment and growth, and ensuring the proper operation and long-term reliability of the mechanism.

[0043] Reference Figures 2 to 6According to the present invention, a dynamic submarine cable quick release device 10 for isolating marine organism attachment is provided. The automatic installation and release mechanism 400 includes multiple spring-embedded latch assemblies 410, a cylinder assembly 420 and a turntable displacement assembly 430. The plug-in cylinder 110 is provided with multiple first lock holes corresponding to the spring-embedded latch assemblies 410 along its circumferential direction. The multiple spring-embedded latch assemblies 410 are respectively connected to the turntable displacement assembly 430 in a transmission manner. The cylinder assembly 420 is connected to the turntable displacement assembly 430. The cylinder assembly 420 is used to drive the turntable displacement assembly 430 to rotate to drive the spring-embedded latch assembly 410 to move through the first lock holes.

[0044] It will be appreciated that the spring-embedded latch assembly 410 is the component that locks and releases the male plug 200 and the female plug 100. Each latch assembly comprises a latch slider 412 and an internal spring 610. When the latch slider 412 is compressed, it can be inserted into or removed from the first locking hole of the female plug 100, thereby locking or releasing the male plug 200. The internal spring 610 provides the latch slider 412 with an automatic reset function. When the external force is removed, the latch slider 412 automatically returns to its initial position under the action of the spring 610, ensuring the reliability and stability of the device.

[0045] The oil cylinder assembly 420 is the power source for the automatic installation and release mechanism 400. It drives the turntable displacement assembly 430 to rotate through the telescopic action of the oil cylinder push rod 422, thereby driving the spring embedded latch assembly 410 to move.

[0046] The turntable displacement assembly 430 is an intermediate component connecting the oil cylinder assembly 420 and the spring embedded latch assembly 410. It transmits the power of the oil cylinder assembly 420 to the latch assembly, realizing the telescopic motion of the latch slide 412.

[0047] The first locking hole is formed in the circumferential direction of the plug barrel 110 and corresponds to the spring embedded latch assembly 410. The latch slider 412 is inserted into the first locking hole to achieve positioning and locking of the male plug 200.

[0048] In this way, through the coordinated action of the spring embedded latch assembly 410, the cylinder assembly 420 and the turntable displacement assembly 430, the male plug 200 and the female plug 100 are quickly and accurately locked and released.

[0049] Reference Figures 2 to 6According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, the automatic installation and release mechanism 400 also includes a plurality of closed boxes 440, and the plurality of closed boxes 440 are arranged in a one-to-one correspondence with the plurality of spring embedded latch assemblies 410. The sealing cover of the closed box 440 is arranged on the outside of the spring embedded latch assembly 410 or the cylinder assembly 420, and is connected and fixed to the outer wall of the plug-in tube 110.

[0050] As will be appreciated, the sealed cover of the enclosed housing 440 is located outside the spring-embedded latch assembly 410 or the cylinder assembly 420, completely isolating these components from the external seawater environment. This effectively prevents marine organisms from entering the internal space, preventing their attachment and growth. By isolating marine organisms, corrosion and mechanical failures caused by their attachment are reduced, thereby improving the long-term stability and reliability of the equipment.

[0051] The closed box 440 is fixedly connected to the outer wall of the plug-in tube 110 to form an integral structure. This design enhances the structural stability of the entire automatic installation and release mechanism 400, ensuring that the connection and movement between components are more stable in complex marine environments.

[0052] Reference Figures 2 to 6 According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, the spring embedded latch assembly 410 includes an elastic member 411 and a latch slider 412. The latch slider 412 corresponds to the first lock hole. The elastic member 411 is connected between the inner wall of the closed box 440 and the end surface of the latch slider 412 away from the first lock hole. A displacement groove is provided on the latch slider 412, and the latch slider 412 is connected to the turntable displacement assembly 430 through the displacement groove.

[0053] It will be appreciated that elastic member 411 (e.g., spring 610) is connected between the inner wall of the enclosed housing 440 and the end surface of the latch slider 412 facing away from the first lock hole. Its primary function is to provide elastic force to the latch slider 412, enabling it to automatically return to its initial position when not subject to external forces. When the latch slider 412 is pushed by an external force (e.g., by the cylinder assembly 420 acting through the turntable displacement assembly 430), the elastic member 411 is compressed. Once the external force disappears, the elastic force of the elastic member 411 automatically resets the latch slider 412, ensuring that it can be accurately inserted into or removed from the first lock hole. This automatic reset function makes the movement of the latch slider 412 more flexible, reduces manual intervention, and simplifies the operation process.

[0054] The latch slider 412 is the component that locks and releases the male plug 200 and the female plug 100. The latch slider 412 corresponds to the first locking hole. Inserting or withdrawing the latch slider from the first locking hole locks or releases the male plug 200. The latch slider 412 moves linearly within the enclosed housing 440, its movement controlled by the elastic member 411 and the rotary disk displacement assembly 430. The precise fit of the latch slider 412 with the first locking hole ensures a stable connection between the male plug 200 and the female plug 100.

[0055] The latch slider 412 is provided with a shifting slot, which is connected to the rotary disk shifting assembly 430. The rotary disk shifting assembly 430 rotates, driving the latch slider 412 within the shifting slot, thereby extending and retracting the latch slider 412. The design of the shifting slot ensures the precise movement direction and position of the latch slider 412, allowing the latch slider 412 to be accurately inserted into or removed from the first lock hole.

[0056] Reference Figures 2 to 6 According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, the cylinder assembly 420 includes a cylinder body 421 and a cylinder push rod 422. The cylinder body 421 is installed on the outside of the closed box 440, and the cylinder push rod 422 is sealed and penetrated through the closed box 440. One end of the cylinder push rod 422 is connected to the output end of the cylinder body 421, and the other end is connected to the connecting rod pin of the turntable displacement assembly 430.

[0057] It is understandable that the oil cylinder body 421 provides the power to drive the turntable displacement assembly 430. It pushes the oil cylinder push rod 422 to expand and contract through the pressure of the hydraulic oil, thereby realizing the driving of the turntable displacement assembly 430.

[0058] The cylinder push rod 422 connects the cylinder body 421 to the turntable displacement assembly 430. It transmits power from the cylinder body 421 to the turntable displacement assembly 430, enabling the retractable movement of the latch slider 412. The cylinder push rod 422 is sealed within the enclosed housing 440 to prevent seawater from entering the enclosed housing 440.

[0059] The connecting rod pin connects the cylinder push rod 422 and the turntable shift assembly 430. It converts the linear motion of the cylinder push rod 422 into the rotational motion of the turntable shift assembly 430. Through the connecting rod pin, the turntable shift assembly 430 can flexibly respond to the movement of the cylinder push rod 422, improving the operational flexibility of the equipment.

[0060] Reference Figure 7According to the present invention, a dynamic submarine cable quick release device 10 for isolating marine organism attachment also includes a spring locking tongue mechanism 600, which is connected to the traction component 300. The spring locking tongue mechanism 600 has a first compressed state in which it is accommodated in the traction component 300, and a second extended state in which the traction component 300 is locked with the male plug 200 after being unfolded.

[0061] The spring lock tongue mechanism 600 is connected to the traction component 300 and has two states: First compression state: in the normal connection state, the locking tongue 620 is accommodated inside the traction component 300 and does not interfere with the movement of other components.

[0062] Second extended state: When release is required, the locking tongue 620 is unfolded to lock the traction component 300 and the male plug 200 together to prevent the traction component 300 and the male plug 200 from accidentally separating during the release process, thereby ensuring that the release process is safe and controllable.

[0063] The spring latch mechanism 600 provides additional security, ensuring the safety and controllability of the release process.

[0064] Reference Figure 7 According to a quick release device 10 for isolating a dynamic submarine cable from marine organism attachment provided by the present invention, a spring pin locking mechanism 500 includes a pushing shaft 510 and an internal spring pin 520. A first mounting groove 310 is opened on the outer wall of the traction component 300, and the internal spring pin 520 is installed in the first mounting groove 310. The male plug 200 is opened with a first through hole 220 corresponding to the first mounting groove 310, and the pushing shaft 510 is limitedly penetrated into the first through hole 220; when the spring pin locking mechanism 500 is in the first locking state, the internal spring pin 520 abuts against the pushing shaft 510, and part of the internal spring pin 520 penetrates into the first through hole 220; when the spring pin locking mechanism 500 is in the second unlocking state, the internal spring pin 520 is separated from the pushing shaft 510, and the internal spring pin 520 is accommodated in the first mounting groove 310.

[0065] It is understandable that the pushing shaft 510 is limitedly penetrated in the first through hole 220 of the male plug 200. When unlocking is required, the pushing shaft 510 pushes the internal elastic pin 520 through mechanical action to change it from the first locked state to the second unlocked state.

[0066] The internal spring pin 520 is installed in the first mounting slot 310 of the pulling member 300 and is the component that locks and unlocks the spring pin locking mechanism 500. In the first locked state, the internal spring pin 520 abuts the driving shaft 510 and partially penetrates the first through-hole 220, locking the male plug 200 and the pulling member 300. In the second unlocked state, the internal spring pin 520 separates from the driving shaft 510 and is received in the first mounting slot 310, thus unlocking the plug.

[0067] The internal spring pin 520 is elastic and can be deformed under the action of the driving shaft 510, thereby achieving the locking and unlocking functions.

[0068] The first mounting groove 310 is formed on the outer wall of the pulling member 300 and is used to fix the internal elastic pin 520 and provide a movement guide for the internal elastic pin 520. The design of the first mounting groove 310 ensures the stability and accuracy of the internal elastic pin 520 during movement.

[0069] A first through-hole 220 is provided on the male plug 200, corresponding to the first mounting slot 310, providing a passage for the driving shaft 510. The driving shaft 510 is positioned within the first through-hole 220, ensuring the precise and stable movement of the driving shaft 510. The cooperation between the first through-hole 220 and the driving shaft 510 ensures the precise movement of the internal spring pin 520 during locking and unlocking.

[0070] Among them, the first through-hole 220 is provided with a limiting step on its axial inner wall, and the end of the pushing shaft 510 away from the inner wall elastic pin is formed with a limiting protrusion that cooperates with the limiting step. When the elastic pin locking mechanism 500 is changed from the first locking state to the second unlocking state, the limiting step cooperates with the limiting protrusion to separate the pushing shaft 510 from the internal elastic pin 520 to achieve unlocking.

[0071] Reference Figure 7 According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, the end of the pushing shaft 510 away from the axial direction of the traction component 300 is arranged in an arc shape, and the plug interface of the plug-in tube 110 is arranged in a trumpet shape. When the elastic pin locking mechanism 500 is transformed from the first locking state to the second unlocking state, the pushing shaft 510 abuts and squeezes the plug interface through the arc-shaped end, so that the pushing shaft 510 compresses the internal elastic pin 520, so that the internal elastic pin is completely accommodated in the first installation groove 310.

[0072] It is understood that the end of the push shaft 510 away from the axial center of the pulling member 300 is designed to be arc-shaped, which matches the trumpet-shaped design of the plug-in socket of the plug-in cylinder 110. When the unlocking operation is required, the arc-shaped end of the push shaft 510 contacts the trumpet-shaped plug-in socket of the plug-in cylinder 110 and generates a squeezing effect.

[0073] The insertion opening of the plug-in sleeve 110 is designed in a flared shape, which guides the arcuate end of the push shaft 510 into contact and generates an inward force component. This inward force acts on the push shaft 510, causing it to move toward the axis of the traction member 300, thereby compressing the internal spring pin 520. The interaction between the push shaft 510 and the insertion opening of the plug-in sleeve 110 enables the spring pin locking mechanism 500 to transition from the first locked state to the second unlocked state.

[0074] When unlocking is required, external force (such as mechanical force or hydraulic pressure) is applied to the male plug 200, causing the arcuate end of the push shaft 510 to contact the flared insertion opening of the plug barrel 110. Due to the shape of the flared insertion opening, the push shaft 510 is subjected to an inward force component, which overcomes the elastic force of the internal spring pin 520, causing the push shaft 510 to move inward and compress the internal spring pin 520. When the internal spring pin 520 is fully compressed and accommodated in the first mounting slot 310, the spring pin locking mechanism 500 transitions from the first locked state to the second unlocked state, effectively unlocking the traction component 300 from the male plug 200.

[0075] Reference Figure 7 According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, the spring lock tongue mechanism 600 includes a spring 610 and a lock tongue 620. A second mounting groove 320 is provided on the outer wall of the traction component 300. One end of the spring 610 is connected to the bottom of the second mounting groove 320, and the other end is connected to the lock tongue 620. A clamping groove 230 is provided on the inner wall of the through hole 210 corresponding to the second mounting groove 320; when the spring lock tongue mechanism 600 is in a first compressed state, the lock tongue 620 is fixedly accommodated in the second mounting groove 320 by a fastener; when the spring lock tongue mechanism 600 is in a first extended state, the lock tongue 620 abuts against the inner wall of the through hole 210 or is limited to the clamping groove 230.

[0076] It is understood that the spring lock tongue mechanism 600 is composed of a spring 610 and a lock tongue 620. The spring 610 provides elastic force, allowing the lock tongue 620 to move under the action of an external force and return to its original position after the external force disappears. The lock tongue 620 is directly involved in the locking and unlocking actions.

[0077] The second mounting slot 320 provides space for the locking tongue 620 to be installed and move, and guides its movement. The second mounting slot 320, defined on the outer wall of the pulling member 300, provides a fixed track for the locking tongue 620. In the first compressed state, the locking tongue 620 is fully contained within the second mounting slot 320 and secured by a fastener, preventing it from accidentally popping out.

[0078] One end of the spring 610 is connected to the bottom of the second mounting slot 320, providing a stable support point. The other end is connected to the lock tongue 620, directly applying the elastic force of the spring 610 to the lock tongue 620. When the lock tongue 620 is subjected to an external force, the spring 610 elastically deforms, storing energy. When the external force disappears, the spring 610 returns to its original shape, pushing the lock tongue 620 back to its original position.

[0079] The slot 230 is formed on the inner wall of the through hole 210 and corresponds to the second mounting slot 320. The slot 230 provides a locking position for the locking tongue 620. When the locking tongue 620 is abutted and located in the slot 230, the traction member 300 and the male plug 200 are locked.

[0080] In the first compressed state, the lock tongue 620 is fixedly received in the second mounting groove 320 by a fastener, thereby ensuring that the lock tongue 620 will not pop out accidentally and affect the normal use of the device.

[0081] In the first extended state, the locking tongue 620 pops out under the action of the spring 610 and abuts against the inner wall of the through hole 210 or the locking groove 230, ensuring that the pulling component 300 and the male plug 200 can be locked again.

[0082] Reference Figure 7 According to a dynamic submarine cable quick release device 10 for isolating marine organism attachment provided by the present invention, a limit block 700 is provided in the through hole 210 at one end close to the submarine cable 20, and the limit block 700 is used to cooperate with the spring lock tongue mechanism 600 to limit the traction component 300.

[0083] It will be appreciated that the stopper 700 is disposed within the through hole 210 near one end of the submarine cable 20 and is capable of cooperating with the locking tongue 620 of the spring locking tongue mechanism 600. When the locking tongue 620 of the spring locking tongue mechanism 600 is extended and abuts the inner wall of the through hole 210 or the slot 230, the stopper 700 further restricts the movement of the traction component 300, ensuring its fixed position. The use of the stopper 700 in conjunction with the spring locking tongue mechanism 600 effectively improves the stability and reliability of the connection between the traction component 300 and the male plug 200, prevents accidental movement or disengagement, and enhances the safety of the quick release device for the dynamic submarine cable 20.

[0084] Reference Figure 1 According to the present invention, a dynamic submarine cable quick release device 10 for isolating marine organism attachment also includes a bending reinforcement member 800, which is sheathed at the connection between the submarine cable 20 and the traction component 300 and is fixedly connected to the male plug 200.

[0085] As will be understood, the bend stiffener 800, applied externally to the connection between the submarine cable 20 and the traction member 300, primarily serves to enhance the structural strength of this connection. The submarine cable 20 is subjected to various complex mechanical forces in the marine environment, such as tension and bending forces. The bend stiffener 800 effectively disperses these forces, reducing stress concentration at the connection. By strengthening the connection, the bend stiffener 800 prevents damage to the submarine cable 20 or the traction member 300 due to external forces, ensuring the stability of the connection.

[0086] 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.
