Description

Technical Field

[0002] Submarine cable, also known as submarine cable, is a telecommunication line installed on the seabed. Offshore wind power cables are mostly installed from the seabed to the top of the platform through rigid protective pipes. To ensure that the submarine cable passes through the protective pipe smoothly, the inner diameter of the submarine cable protective pipe is generally about three times the outer diameter of the submarine cable.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] Please refer to Figures 1 to 4 Figures 1 to 4 , the present utility model provides an offshore wind power submarine cable clamping device, including a clamping body 1. The end face of the clamping body 1 has a submarine cable through hole 2 for threading the submarine cable. A plurality of mounting holes 3 are circumferentially spaced on the lower end face of the clamping body 1 and extend upward along the height direction of the clamping body 1. A spreading component 4 is arranged in each mounting hole 3. A clamping plate 5 for clamping and fixing the submarine cable and a fixing plate 6 for fixing with the submarine cable sheath are respectively connected to the spreading component 4. The clamping plate 5 and the fixing plate 6 are respectively located on the inner and outer sides of the submarine cable through hole 2. A pushing member 7 is inserted into the mounting hole 3. When the pushing member 7 is inserted into the mounting hole 3, it can drive the spreading component 4 to spread and clamp the clamping plate 5 against the submarine cable, and at the same time spread the fixing plate 6 to abut against the inner wall of the submarine cable sheath.

[0028] In this solution, both the clamping plate 5 and the fixing plate 6 are arc-shaped plates. When a plurality of the clamping plates 5 are surrounded and close to each other, the diameter of the clamping space formed is matched with the diameter of the submarine cable. When a plurality of the fixing plates 6 are spread away from the clamping body 1 like an umbrella, the outer diameter of the space formed by the plurality of the fixing plates 6 surrounded is matched with the inner diameter of the submarine cable sheath. And rubber pads (not marked in the figure, but those skilled in the art should understand the installation position of the rubber pads) are respectively installed on the inner surface of the clamping plate 5 and the outer surface of the fixing plate 6. The outer surface of the rubber pad has a number of spherical protrusions (not shown in the figure), so as to increase the contact area between the clamping plate 5 and the submarine cable, and between the fixing plate 6 and the submarine cable sheath, so as to improve the fixing effect.

[0029] During use, first thread the submarine cable into the submarine cable through hole 2, then install the clamping body 1 into the submarine cable sheath, and then insert the pushing member 7 at the bottom of the clamping body 1. When the pushing member 7 is inserted into the mounting hole 3, the pushing member 7 simultaneously pushes the spreading components 4 installed in a plurality of the mounting holes 3 to slide along the mounting holes 3. When the spreading components 4 slide, they spread the clamping plate 5 close to the submarine cable and at the same time spread the fixing plate 6 close to the submarine cable sheath. Through the cooperation of multiple groups of the spreading components 4, the clamping plates 5 and the fixing plates 6, a plurality of the clamping plates 5 can be driven to surround and clamp and fix the submarine cable, and at the same time a plurality of the fixing plates 6 can be driven to spread like an umbrella and abut against the inner wall of the submarine cable sheath for fixing, so as to realize stably clamping and fixing the submarine cable in the submarine cable sheath. By arranging the submarine cable clamping device of the present utility model between the submarine cable and the submarine cable sheath, the submarine cable can be centered and clamped and fixed in the submarine cable sheath, and the distance between the submarine cable and the submarine cable sheath is ensured, thus effectively avoiding the submarine cable from constantly swinging and colliding with the sheath under the action of ocean currents, and improving the service life of the submarine cable.

[0030] Please refer toFigure 2 and Figure 3 , in this embodiment, the expanding component 4 includes a movable block 41 slidably connected to the mounting hole 3. A through groove 42 is formed in the side wall of the fixture body 1, and the through groove 42 radially penetrates the fixture body 1; on each movable block 41, two grooves 43 are symmetrically arranged on the upper part of the movable block 41, and a set of support mechanisms 44 are respectively arranged in the two grooves 43. The two sets of support mechanisms 44 are respectively connected to the fixed plate 6 and the clamping plate 5; each set of support mechanisms 44 includes a first connecting member 441 fixedly connected to the groove 43 and a support rod 442 hinged to the first connecting member 441. One end of the support rod 442 away from the first connecting member 441 is hinged to the fixed plate 6.

[0031] When the pushing member 7 is inserted into the mounting hole 3, the pushing member 7 pushes the movable block 41 to slide along the mounting hole 3. When the movable block 41 slides, one end of the support rod 442 is driven by the first connecting member 441 to move upward. At this time, the support rod 442 rotates relative to the first connecting member 441 and gradually changes from an inclined state to a horizontal state. When the movement of the support rod 442 tends to be horizontal, the two support rods 442 mounted on the movable block 41 respectively expand the clamping plate 5 to clamp the submarine cable and expand the fixed plate 6 to abut against the inner wall of the submarine cable protection pipe near the submarine cable protection pipe, so as to realize stably clamping and fixing the submarine cable in the submarine cable protection pipe.

[0032] Please refer to Figure 2 , in this embodiment, a sliding groove 443 is formed on the outer circumferential surface of the fixture body 1. Each set of support mechanisms 44 further includes a sliding rod 444 slidably connected to the sliding groove 443. The sliding rod 444 can slide along the length direction of the sliding groove 443 and will not be separated from the sliding groove 443. An auxiliary rod 445 is hinged to the sliding rod 444. One end of the auxiliary rod 445 away from the sliding rod 444 is hinged to the fixed plate 6, and when the expanding component 4 expands the fixed plate 6, the auxiliary rod 445 is in an inclined state.

[0033] Specifically, when the support rod 442 tends to move horizontally to expand the fixed plate 6 close to the submarine cable protection pipe, one end of the auxiliary rod 445 rotates relative to the fixed plate 6, the other end of the auxiliary rod 445 rotates relative to the sliding rod 444, and slides through the sliding rod 444 in the T-shaped chute 443, so as to support and assist the movement of the fixed plate 6, so that the fixed plate 6 can directly abut against the inner wall of the submarine cable protection pipe along the radial direction of the submarine cable. At the same time, when the fixed plate 6 abuts against the inner wall of the submarine cable protection pipe, the auxiliary rod 445 is in an inclined state, which can assist in supporting the fixed plate 6, improving the stability of the connection between the fixed plate 6 and the submarine cable protection pipe. Finally, the clamping plate 5 can also adopt the above structure to assist the movement of the clamping plate 5 to clamp and fix the submarine cable.

[0034] Please refer to Figure 3 , in this embodiment, side grooves 446 are respectively formed on opposite side walls of the through groove 42, through holes 447 are formed on the support rod 442, a second connecting member 448 is commonly inserted through the through holes 447 and the side grooves 446, both ends of the second connecting member 448 respectively extend into the two side grooves 446, and springs 449 are respectively arranged at both ends of the second connecting member 448, and the other ends of the springs 449 are connected to the bottom wall of the through groove 42.

[0035] Specifically, when the movable block 41 is pushed to slide along the mounting hole 3, the movable block 41 drives the support rod 442 to tend to move horizontally through the first connecting member 441. When the support rod 442 moves, it drives the second connecting member 448 to slide upward along the side groove 446, and when the second connecting member 448 slides, it pulls the upper end of the spring 449 to move, stretching the spring 449. Thus, finally when the pushing member 7 is disassembled, the spring 449 deforms back to its original state, pulling the second connecting member 448 to slide downward along the side groove 446 to reset. When the second connecting member 448 slides, it pulls the support rod 442 to move downward to reset and be inclined, so that the clamping plate 5 moves away from the submarine cable and the fixed plate 6 moves away from the submarine cable protection pipe, and it folds up like an umbrella, so that the clamping device of the present utility model can be quickly disassembled.

[0036] Please refer to Figure 1 , Figure 3 and Figure 4 , in this embodiment, an installation groove 71 is formed on the lower end surface of the fixture body 1. The pushing member 7 includes an installation ring 72 detachably connected to the installation groove 71. A plurality of pushing rods 73 are circumferentially and spacedly arranged on the upper end surface of the installation ring 72. The pushing rods 73 are inserted into the installation hole 3 to be able to push the expanding assembly 4 to expand the clamping plate 5 to clamp the submarine cable, and at the same time expand the fixed plate 6 to abut against the inner wall of the submarine cable protection pipe.

[0037] Specifically, when it is necessary to fix the submarine cable, the mounting ring 72 is installed in the mounting groove 71, and the plurality of push rods 73 are simultaneously inserted into the plurality of mounting holes 3 through the mounting ring 72, thereby simultaneously driving the plurality of expansion components 4 to expand the clamp plates 5 to clamp the submarine cable, expand the fixing plates 6 to abut against the inner wall of the submarine cable protective tube, and fix the submarine cable. Finally, bolts can be used under the mounting ring 72 to pass through the mounting groove 71 and fix it to the clamp body 1.

[0038] See also Figure 3 and Figure 4 In this embodiment, a gasket 74 is fixedly connected to one end of the push rod 73 away from the mounting ring 72, a threaded hole 75 is provided at the bottom of the clamp body 1 along its radial direction, a limiting hole 76 is radially penetrated on the push rod 73, and a limiting member 77 is connected to the threaded hole 75 and the limiting hole 76; the limiting member 77 includes a twisting portion 771 and a connecting portion 772, and an inclined surface 773 is provided at one end of the connecting portion 772 away from the twisting portion 771.

[0039] Specifically, the top of each push rod 73 is fixedly connected with an elastic gasket 74, so that when the mounting ring 72 is installed in the mounting groove 71, the mounting ring 72 does not enter the mounting groove 71 completely. At this time, the limiting hole 76 on the push rod 73 partially overlaps with the threaded hole 75. By screwing the limiting member 77 into the threaded hole 75, the external thread on the connecting portion 772 cooperates with the threaded hole 75 to move, squeezing and pushing the push rod 73 upward, and the inclined surface 773 facilitates the connecting portion 772 to smoothly penetrate the limiting hole 76 from the threaded hole 75. At this time, the limiting member 77 Part 77 pulls the mounting ring 72 upward to completely enter the mounting groove 71, and the gasket 74 is squeezed and deformed to generate a force that makes the push rod 73 abut against the connecting portion 772 of the limiting member 77, so that the limiting member 77 stably connects the clamp body 1 and the pushing rod 73, completing the installation of the pushing member 7. Since the submarine cable swings under the action of the ocean current, compared with using bolts to fix the installation below the pushing member 7, fixing it on the side of the pushing member 7 can better resist the thrust of the ocean current and bending stress, making the installation of the pushing member 7 more stable, so as to drive the support assembly 4 to stably clamp and fix the submarine cable.

[0040] 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 them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
