Description

Technical Field

[0001] The present invention relates to the field of submarine cables, and in particular to a submarine cable reinforcement component and a submarine cable structure. Background Art

[0002] With the rapid development of offshore oil and gas projects, especially offshore floating wind turbines, bending reinforcements are generally used to enhance the bending strength of the tail of dynamic submarine cables landing on offshore platforms, and their application is becoming increasingly widespread.

[0003] Currently, the mainstream method for installing bend stiffeners on platforms is underwater installation by divers or remote-controlled unmanned submersibles. This involves securing the metal insert inside the bend stiffener to the platform flange using a large number of threaded fasteners. However, bend stiffeners for large-section dynamic submarine cables are generally large in size, contain heavy metal inserts inside, and are secured to the platform flange using a large number of fixing bolts. The drawbacks of underwater installation by divers and remote-controlled unmanned submersibles are as follows: underwater positioning and installation by divers are difficult, and even in environments with rapid currents or great depths, installation is not practical and presents significant safety risks. Remote-controlled unmanned submersibles can address the deep water problem, but remote-controlled unmanned submersibles are difficult to control underwater and have low power, making them difficult to pull on the rigid, large-section dynamic submarine cables and their accompanying bend stiffeners.

[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0044] In the description of the embodiments of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0045] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0046] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0047] The following combination Figures 1 to 7 The submarine cable reinforcement provided by an embodiment of the present invention is described. The submarine cable reinforcement is used to strengthen the strength of the submarine cable 200 to prevent the submarine cable 200 from fatigue damage under the long-term action of ocean currents.

[0048] In this embodiment, the submarine cable reinforcement member includes: a clamp 100 , a reinforcement member 300 and a positioning member 400 .

[0049] The clamp 100 is used to secure the submarine cable 200. It has a channel 1000 for threading the submarine cable. The submarine cable 200 passes through the channel 1000, thereby being wrapped and secured by the clamp 100. A reinforcement member 300 is connected to one end of the clamp 100. The reinforcement member 300 has a mounting hole 3000 for threading the submarine cable 200, which communicates with the channel 1000.

[0050] In this embodiment, the reinforcement member 300 is used to increase the bending stress of the submarine cable 200. The reinforcement member 300 is coaxially arranged relative to the clamp 100. The reinforcement member 300 is connected to the bottom of the clamp 100, and the mounting hole 3000 is aligned with the insertion groove 1000 at the top. The submarine cable 200 is fixed through the insertion groove 1000 and the mounting hole 3000 in sequence. At this time, after the reinforcement member 300 is fixed in place by the clamp 100, the mounting hole 3000 covers the submarine cable, thereby strengthening the strength of the entire submarine cable 200.

[0051] To facilitate user placement of the entire submarine cable reinforcement, the reinforcement 300 can be secured via a positioning member 400 on the offshore platform. Positioning member 400 is positioned opposite reinforcement 300 and has a through-hole for insertion of reinforcement 300. The through-hole of positioning member 400 can be a bell-shaped hole, and a stopper 500 is provided on the inner wall of the through-hole. The stopper 500 has two positions: locked and unlocked.

[0052] like Figure 4 and Figure 7 As shown, when the limiting member 500 is in the unlocked state, the limiting member 500 is separated from the reinforcement member 300, so that the entire submarine cable 200, in coordination with the clamp 100 and the reinforcement member 300, can move up and down relative to the entire positioning member 400, making it convenient for the user to adjust the fixed position of the submarine cable 200.

[0053] like Figure 3 and Figure 6 As shown, when the stopper 500 is in a locked state, the stopper 500 abuts against the reinforcement member 300. Thus, the entire submarine cable 200 is fixed to the positioning member 400 in coordination with the clamp 100 and the reinforcement member 300. When the positioning member 400 is fixed to the offshore platform, the entire submarine cable reinforcement member can fix the submarine cable 200 to the offshore platform.

[0054] During the installation of the submarine cable 200 using the submarine cable reinforcement member, the submarine cable 200 is first passed through the threading slot 1000 of the clamp 100 to secure the submarine cable 200. The submarine cable 200 is then passed through the installation hole 3000 and the reinforcement member 300 is secured to the clamp 100. The submarine cable 200 is then aligned with the threading hole and slowly lowered directly using a traction device. At this point, the position limiting member 500 is controlled to be adjusted to an unlocked state, allowing the submarine cable 200, the clamp 100, and the reinforcement member 300 to move downward under the restraint of their own weight. Once in place, the position limiting member 500 is controlled to be adjusted to a locked state, and the submarine cable 200, in conjunction with the clamp 100 and the reinforcement member 300, is secured to the positioning member 400. This completes the installation of the submarine cable 200 and the submarine cable reinforcement member, effectively preventing the submarine cable 200 from rotating along its central axis due to ocean currents.

[0055] The submarine cable reinforcement provided by the embodiment of the present invention fixes and limits the submarine cable through a clamp, and at the same time, a reinforcement is arranged on the clamp to strengthen the strength of the submarine cable, and the reinforcement and the clamp are positioned in conjunction with the positioning piece. During the placement of the submarine cable, the limiting piece is controlled to be adjusted to an unlocked state, and the limiting piece is separated from the reinforcement piece. Gravity is first used to make the reinforcement piece cooperate with the submarine cable in the penetration hole. After it is installed in place, the limiting piece is controlled to be adjusted to a locked state, and the limiting piece is abutted against the reinforcement piece to achieve a limiting effect, thereby greatly simplifying the installation and fixation of the submarine cable reinforcement piece. There is no need for divers or remote-controlled unmanned submersibles to adjust the state of the bent reinforcement piece underwater, thereby improving the safety and feasibility of installation.

[0056] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the clamp 100 includes a first clamp 101 and a second clamp 102 .

[0057] The first clamp 101 serves as the upper clamp and has a first cavity 1001 therein for threading the submarine cable 200. The second clamp 102 serves as the lower clamp and docks with the first clamp 101. The second clamp 102 has a second cavity 1002 therein for threading the submarine cable 200. After the second clamp 102 docks with the first clamp 101, the second cavity 1002 communicates with the first cavity 1001 to form a threading slot 1000.

[0058] To ensure a tight seal after the first clamp 101 and the second clamp 102 are connected, one of the first clamp 101 and the second clamp 102 is provided with a thread, and the other is provided with a matching thread groove. Thus, after the submarine cable 200 is passed through the first clamp 101 and the second clamp 102, the first clamp and the second clamp 102 are connected by threads. In addition, a sealing ring can be provided between the first clamp 101 and the second clamp 102 to further improve the sealing performance after the first clamp 101 and the second clamp 102 are connected.

[0059] Depending on the position to be reinforced, the reinforcement member 300 may be connected to the first clamp 101 or the second clamp 102 .

[0060] For example, when the reinforcement member 300 is connected to the side of the first clamp 101 away from the second clamp 102, the mounting hole 3000 in the reinforcement member 300 is aligned with the first cavity 1001, and the entire reinforcement member 300 is used to reinforce the submarine cable 200 at the upper end of the first clamp 101.

[0061] When the reinforcement member 300 is connected to the side of the second fixture 102 away from the first fixture 101 , the mounting hole 3000 in the reinforcement member 300 is aligned with the second cavity 1002 , and the entire reinforcement member 300 is used to reinforce the submarine cable 200 at the lower end of the second fixture 102 .

[0062] In one embodiment, to enhance the stability of the clamp 100 and the submarine cable, a glue injection hole 103 is provided on the first clamp 101 or the second clamp 102, or glue injection holes 103 may be provided on both the first clamp 101 and the second clamp 102. One or more glue injection holes 103 may be provided, each of which is connected to the threading groove 1000. The space between the threading groove 1000 and the submarine cable 200 is filled with a glue, which may be a steel wire fastening glue, to ensure the stability of the connection between the submarine cable 200 and the clamp 100.

[0063] When securing the clamp 100 to the submarine cable 200, first insert the sealing ring into the first clamp 101 or the second clamp 102, and then insert the first clamp 101 and the second clamp 102 into the appropriate position of the submarine cable 200 along the end of the submarine cable 200. Cut the armored steel wires on the submarine cable 200 at the positions corresponding to the first clamp 101 and the second clamp 102, and bend the cable 200 about 7 to 10 degrees along the central axis of the cable 200. After cleaning the asphalt on the surface of the armored steel wires with asphalt cleaning agent, the first clamp 101 and the second clamp 102 are connected to form a threading groove 1000. Then, steel wire fastening glue is injected into the glue injection hole 103 and cured for at least 3 hours, thereby securing the submarine cable 200 to the first clamp 101 and the second clamp 102.

[0064] In order to ensure the sealing of the clamp 100 as a whole, Figure 10 As shown, a first tapered groove is provided at the end of the first cavity 1001 away from the second cavity 1002, that is, the first tapered groove is provided at the upper end of the first cavity 1001. A second tapered groove is provided at the end of the second cavity 1002 away from the first cavity 1001, that is, the second tapered groove is provided at the lower end of the second cavity 1002. A first sealing ring 1003 is provided between the first tapered groove and the submarine cable 200, thereby forming a first sealing surface at the upper end of the first cavity 1001. A second sealing ring 1004 is provided between the second tapered groove and the submarine cable 200. Thus, the second sealing ring 1004 forms a second sealing surface at the lower end of the second cavity 1002. The first sealing surface and the second sealing surface effectively prevent water from entering the threading groove 1000.

[0065] Both the first sealing ring 1003 and the second sealing ring 1004 are conical sealing rings. The first sealing ring 1003 is compressed by the conical ring pressure plate with corresponding fasteners, thereby securing the first sealing ring 1003 in the first conical groove, forming a first sealing surface. Simultaneously, the second sealing ring 1004 is compressed by the conical ring pressure plate with corresponding fasteners, thereby securing the second sealing ring 1004 in the second conical groove, forming a second sealing surface.

[0066] like Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the submarine cable reinforcement further includes: a plurality of pressure plates, a positioning ring 800 and fasteners.

[0067] In this embodiment, the submarine cable reinforcement member further includes: a first pressure plate 600, a second pressure plate 700, a positioning ring 800, and a fastener 801. The first and second pressure plates 600, 700 are each designed to be mounted on the outside of the submarine cable 200. The positioning ring 800 is a polyurethane positioning ring and is mounted on the outside of the submarine cable 200. The positioning ring 800 is positioned between the first and second pressure plates 600, 700. The fastener 801 is a long screw that passes through the first pressure plate 600, the positioning ring 800, and the second pressure plate 700 in sequence and is installed in the clamp 100. The clamp 100 is connected to the first pressure plate 600, the second pressure plate 700, and the positioning ring 800 via the fastener 801, thereby ensuring the connection strength between the clamp 100 and the submarine cable 200.

[0068] Specifically, the positioning rings 800 are fixed to the pressure plate using fasteners 801. Each positioning ring 800 is supported by a pressure plate. After installation, the positioning rings 800 and the submarine cable 200 are in a transitional fit state.

[0069] To further enhance the connection between the clamp 100 and the submarine cable 200, the submarine cable reinforcement includes a first pressure plate 600, a second pressure plate 700, a third pressure plate, and a fourth pressure plate. The first, second, third, and fourth pressure plates are all designed to be mounted on the outside of the submarine cable 200. The positioning ring 800, made of polyurethane, is designed to be mounted on the outside of the submarine cable 200. Three positioning rings are provided, one between the first and second pressure plates 600 and 700, one between the second and third pressure plates 700, and one between the third and fourth pressure plates. Accordingly, three sets of fasteners 801 are also provided, with each set of fasteners 801 inserted through a corresponding pressure plate and positioning ring 800. By providing more pressure plates, the connection strength between the clamp 100 and the submarine cable 200 can be further enhanced.

[0070] In addition, the submarine cable reinforcement member also includes a guide member 900 and an insert 901. The guide member 900 is a truncated cone or conical polyurethane structure for easy guidance. The small diameter end of the guide member 900 is located on the side away from the first pressure plate 600, and the large diameter end of the guide member 900 abuts the first pressure plate 600. The guide member 900 is designed to be mounted on the outside of the submarine cable 200. The guide member 900 is constructed with a mounting groove extending circumferentially along the submarine cable 200. The insert 901 is made of metal and is disposed in the mounting groove to strengthen the entire guide member 900.

[0071] Specifically, the guide member 900 is set on the topmost pressure plate, and the insert 901 is set in the installation groove. The insert 901 is used to enhance the strength of the guide member 900. The insert 901 can be threadedly connected to the guide member 900 to facilitate the fixation of the structure.

[0072] To connect the reinforcement member 300 to the clamp 100, one of the reinforcement member 300 and the clamp 100 is provided with a protrusion 3001, and the other of the reinforcement member 300 and the clamp 100 is provided with a groove 1020 that matches the protrusion 3001. In other words, when the reinforcement member 300 is provided with the protrusion 3001, the clamp 100 is provided with the groove 1020. Conversely, when the reinforcement member 300 is provided with the groove 1020, the clamp 100 is provided with the protrusion 3001. The reinforcement member 300 is connected to the clamp 100 via the protrusion and the groove.

[0073] Specifically, if Figure 1 and Figure 5 As shown, the reinforcement 300 is provided with a plurality of protrusions 3001, which are bent reinforcement inserts. Correspondingly, the bottom of the second fixture 102 is provided with a plurality of grooves 1020 that match the plurality of protrusions 3001. When all the protrusions 3001 are aligned with all the grooves 1020, the reinforcement 300 can be connected to the bottom of the second fixture 102.

[0074] Based on the above embodiments, in one embodiment, Figures 3 to 7 As shown, the position-limiting member includes a rotating baffle 501. The rotating baffle 501 is rotatably connected to the inner wall of the perforated hole via a rotating shaft. Rotating the rotating baffle 501 adjusts the position-limiting condition. When the rotating baffle 501 is unlocked, the rotating baffle 501 rotates until it is separated from the reinforcement 300. When the rotating baffle 501 is locked, the rotating baffle 501 rotates until it abuts the reinforcement 300.

[0075] Specifically, the position-limiting member further comprises: a plurality of pivot brackets 502. The pivot brackets 502 are sequentially arranged along the inner wall of the through-hole, with a rotating baffle 501 positioned between two adjacent pivot brackets 502. When the rotating baffle 501 is unloaded, its own weight allows it to abut against the reinforcement 300, achieving a position-limiting effect. When a force is applied to the rotating baffle 501, the rotating baffle 501 separates from the reinforcement 300.

[0076] like Figure 4 and Figure 7 As shown, when the pivot bracket 502 is in the unlocked state, the pivot bracket 502 is separated from the reinforcement member 300, so that the entire submarine cable 200, in coordination with the clamp 100 and the reinforcement member 300, can move up and down relative to the entire positioning member 400, making it convenient for the user to adjust the fixed position of the submarine cable 200.

[0077] like Figure 3 and Figure 6 As shown, when the pivot bracket 502 is in a locked state, the pivot bracket 502 abuts against the reinforcement member 300. Thus, the entire submarine cable 200 is fixed to the offshore platform in coordination with the clamp 100 and the reinforcement member 300. When the reinforcement member 400 is fixed to the offshore platform, the entire submarine cable reinforcement member can fix the submarine cable 200 to the offshore platform.

[0078] In this embodiment, the clamp 100 is provided with a positioning protrusion 1005, and a plurality of rotating baffles 501 are provided. The rotating baffles 501 are sequentially spaced along the radial direction of the perforation hole, and positioning grooves that match the positioning protrusions 1005 are formed between adjacent rotating baffles 501. By placing the positioning protrusions 1005 in the positioning grooves, the clamp 100 and the positioning member 400 are fixed, effectively preventing the submarine cable reinforcement member from rotating along the central axis of the submarine cable 200 due to ocean currents.

[0079] Generally, the clamp 100 is provided with a plurality of positioning protrusions 1005 and correspondingly constructed with a plurality of positioning grooves. When the plurality of positioning protrusions 1005 are all arranged in the positioning grooves, the positioning grooves and the positioning protrusions 1005 can be used to complete the fixation of the clamp 100 and the positioning member 400.

[0080] In a specific embodiment, Figures 1 to 14 As shown, since the rotating baffle 501 has both rotatable and fixed limiting functions, the installation process is as follows: during underwater observation using a remote-controlled unmanned submersible, the pulling angle of the submarine cable 200 is appropriately adjusted so that the second clamp 102 is located between the two rotating baffles 501, and then the submarine cable 200 is continued to be pulled. At this time, the rotating baffle 501 rotates along the rotation axis under the push of the reinforcement member 300 until the bottom of the second clamp 102 is affixed to the lower end surface of the through hole, and the positioning protrusion 1005 is located between the two rotating baffles 501, thereby completing the position limitation of the second clamp 102, which can effectively prevent the submarine cable reinforcement member from rotating along the central axis of the submarine cable 200 under the action of ocean currents.

[0081] The present invention also provides a submarine cable structure, which includes a submarine cable and a submarine cable reinforcement. Figures 1 to 14 As shown,

[0082] The submarine cable reinforcement assembly includes a clamp 100, a reinforcement member 300, and a positioning member 400. The clamp 100 is used to secure the submarine cable 200. The clamp 100 includes a slot 1000 for threading the submarine cable. The submarine cable 200 passes through the slot 1000, thereby being wrapped and secured by the clamp 100. The reinforcement member 300 is connected to one end of the clamp 100. The reinforcement member 300 includes a mounting hole 3000 for threading the submarine cable 200. The mounting hole 3000 communicates with the slot 1000.

[0083] In this embodiment, the reinforcement member 300 is used to increase the bending stress of the submarine cable 200. The reinforcement member 300 is coaxially arranged relative to the clamp 100. The reinforcement member 300 is connected to the bottom of the clamp 100, and the mounting hole 3000 is aligned with the insertion groove 1000 at the top. The submarine cable 200 is fixed through the insertion groove 1000 and the mounting hole 3000 in sequence. At this time, after the reinforcement member 300 is fixed in place by the clamp 100, the mounting hole 3000 covers the submarine cable, thereby strengthening the strength of the entire submarine cable 200.

[0084] To facilitate user placement of the entire submarine cable reinforcement, the reinforcement 300 can be secured via a positioning member 400 on the offshore platform. Positioning member 400 is positioned opposite reinforcement 300 and has a through-hole for insertion of reinforcement 300. The through-hole of positioning member 400 can be a bell-shaped hole, and a stopper 500 is provided on the inner wall of the through-hole. The stopper 500 has two positions: locked and unlocked.

[0085] like Figure 4 and Figure 7 As shown, when the limiting member 500 is in the unlocked state, the limiting member 500 is separated from the reinforcement member 300, so that the entire submarine cable 200, in coordination with the clamp 100 and the reinforcement member 300, can move up and down relative to the entire positioning member 400, making it convenient for the user to adjust the fixed position of the submarine cable 200.

[0086] like Figure 3 and Figure 6 As shown, when the stopper 500 is in a locked state, the stopper 500 abuts against the reinforcement member 300. Thus, the entire submarine cable 200 is fixed to the positioning member 400 in coordination with the clamp 100 and the reinforcement member 300. When the positioning member 400 is fixed to the offshore platform, the entire submarine cable reinforcement member can fix the submarine cable 200 to the offshore platform.

[0087] During the installation of the submarine cable 200 using the submarine cable reinforcement member, the submarine cable 200 is first passed through the threading slot 1000 of the clamp 100 to secure the submarine cable 200. The submarine cable 200 is then passed through the installation hole 3000 and the reinforcement member 300 is secured to the clamp 100. The submarine cable 200 is then aligned with the threading hole and slowly lowered directly using a traction device. At this point, the position limiting member 500 is controlled to be adjusted to an unlocked state, allowing the submarine cable 200, the clamp 100, and the reinforcement member 300 to move downward under the restraint of their own weight. Once in place, the position limiting member 500 is controlled to be adjusted to a locked state, and the submarine cable 200, in conjunction with the clamp 100 and the reinforcement member 300, is secured to the positioning member 400. This completes the installation of the submarine cable 200 and the submarine cable reinforcement member, effectively preventing the submarine cable 200 from rotating along its central axis due to ocean currents.

[0088] The submarine cable structure provided by the embodiment of the present invention fixes and limits the submarine cable by means of a clamp, and at the same time, a reinforcement member is arranged on the clamp to strengthen the strength of the submarine cable, and the reinforcement member and the clamp are positioned in cooperation with the positioning member. During the placement of the submarine cable, the limiting member is controlled to be adjusted to an unlocked state, and the limiting member is separated from the reinforcement member. Gravity is first used to make the reinforcement member cooperate with the submarine cable in the penetration hole. After the installation is in place, the limiting member is controlled to be adjusted to a locked state, and the limiting member is abutted against the reinforcement member to realize the limiting effect, thereby greatly simplifying the installation and fixation of the submarine cable reinforcement member, and there is no need for divers or remote-controlled unmanned submersibles to adjust the state of the bent reinforcement member underwater, thereby improving the installation safety and feasibility.
