TECHNICAL FIELD
[0001] The present application relates to the technical field of clamps, and particularly relates to a submarine cable center clamp. BACKGROUND
[0002] The submarine cable of a sea platform (for example, a booster station or a sea wind turbine) in the sea is led from the seabed to the platform through a protection pipe. Since the diameter of the protection pipe is large, the submarine cable will move in the protection pipe. In order to reduce the friction caused by the swing of the submarine cable in the protection pipe and cause fatigue damage of the submarine cable, a center positioning clamp is arranged between the outer part of the submarine cable and the protection pipe for supporting and protecting. The center positioning clamp comprises a guide head and a positioning component. The guide head and the positioning component are connected. The guide head is composed of two sub-blocks. When the guide head is damaged, at least one sub-block needs to be replaced, so that the replacement cost of the guide head is high. Therefore, the existing center positioning clamp has the problem of high replacement cost of the guide head. CONTENT OF THE UTILITY MODEL
[0003] The present application aims to provide a submarine cable center clamp with low replacement cost of a guide head, which comprises a guide head and a positioning component. The guide head comprises at least three guide blocks. The positioning component and the at least three guide blocks are detachably connected.
[0004] Optionally, the positioning component comprises a first positioning component and a second positioning component, the first positioning component and the second positioning component are detachably connected, the number of the guide blocks is 2N, N is a positive integer greater than 1, the first positioning component and N guide blocks are detachably connected, and the second positioning component and another N guide blocks are detachably connected.
[0005] Optionally, the first positioning component comprises a first rubber pad and a first body, the first rubber pad is clamped between the first body and the N guide blocks, and the first body and the N guide blocks are detachably connected.
[0006] Optionally, the bottom surface diameter of the guide block is less than or equal to the end surface diameter of the first rubber pad.
[0007] Optionally, the submarine cable center clamp further comprises 2N first fasteners, each of the N guide blocks corresponds to two first fasteners, and each first fastener is detachably connected to the corresponding guide block and the first body.
[0008] Optionally, each first fastener is arranged in the first rubber pad.
[0009] Optionally, the second positioning component comprises a second rubber pad and a second body, the first body and the second body are detachably connected, and the second rubber pad is clamped between the second body and the other N guide blocks, and the second body and the other N guide blocks are detachably connected.
[0010] Optionally, the diameter of the bottom surface of the guide block is less than or equal to the diameter of the end surface of the second rubber pad.
[0011] Optionally, the submarine cable center clamp further comprises 2N second fasteners, each of the guide blocks in the other N guide blocks corresponds to two second fasteners, and each second fastener is detachably connected to the corresponding guide block and the second body.
[0012] Optionally, each second fastener penetrates the second rubber pad.
[0013] The beneficial effects of the present application are that by arranging a guide head and a positioning component, the guide head comprises at least three guide blocks, and the positioning component and the at least three guide blocks are detachably connected. Since the guide head is composed of at least three guide blocks, the volume of each guide block is smaller than that of the sub-block, and when a single guide block is damaged, only the damaged guide block needs to be replaced, and other guide blocks do not need to be replaced, thereby reducing the replacement cost of the guide head.

[0037] Please refer to Figure 1 and Figure 2 In the embodiment, a submarine cable center clamp is provided, comprising a guide head 1 and a positioning component 2. The guide head 1 comprises at least 3 guide blocks 10. The positioning component 2 and the at least 3 guide blocks 10 are detachably connected. Since the guide head 1 is composed of at least 3 guide blocks 10, the volume of each guide block 10 will be smaller than that of a sub-block. When a single guide block 10 is damaged, only the damaged guide block 10 needs to be replaced, and other guide blocks 10 do not need to be replaced, thereby reducing the replacement cost of the guide head 1. The guide blocks 10 can be detachably connected to the positioning component 2 through bolts or studs. The side walls of adjacent guide blocks 10 abut against each other.
[0038] Please refer to Figure 1 and Figure 2 Optionally, the positioning component 2 comprises a first positioning assembly 20 and a second positioning assembly 21, the first positioning assembly 20 and the second positioning assembly 21 are detachably connected, the number of guide blocks 10 is 2N, N is a positive integer greater than 1, the first positioning assembly 20 and N guide blocks 10 are detachably connected, and the second positioning assembly 21 and another N guide blocks 10 are detachably connected. The number of guide blocks 10 is 2N, the first positioning assembly 20 and the second positioning assembly 21 correspond to N guide blocks 10 respectively, and the installation of 2N guide blocks 10 can be completed by using the original first positioning assembly 20 and the second positioning assembly 21, without the need to additionally manufacture the positioning component 2, thereby reducing the manufacturing cost of the positioning component 2.
[0039] Please refer to Figure 1 and Figure 2 For example, N can be 2 or 3. When N is 2, the total number of guide blocks 10 is 4. N in the application represents a positive integer greater than 1. The first positioning assembly 20 and the second positioning assembly 21 can be arranged one above the other. The left end of the first positioning assembly 20 and N guide blocks 10 can be detachably connected through a first fastener 3 (for example, the left end of the first positioning assembly 20 can be detachably connected to the upper two guide blocks 10 in the figure). Figure 2
[0040] Please refer to Figure 1 and Figure 2 The left end of the second positioning assembly 21 and the other N guide blocks 10 can be detachably connected by the second fastener 4 (for example, the left end of the second positioning assembly 21 can be detachably connected with the other N guide blocks 10 by the second fastener 4). Figure 2 That is, the first positioning assembly 20 can be connected with half of the guide blocks 10, and the second positioning assembly 21 can be connected with the other half of the guide blocks 10.
[0041] Please refer to Figure 1 and Figure 2 for example. When the total number of guide blocks 10 is four, two of the guide blocks 10 can be connected with the first positioning assembly 20, and the remaining two guide blocks 10 can be connected with the second positioning assembly 21. When the total number of guide blocks 10 is four, the first body 201 and the second body 211 do not need to be re-drilled with screw holes. At this time, the guide blocks 10 can be screwed with the original screw holes on the first body 201 and the second body 211, thereby saving the process of drilling screw holes.
[0042] Please refer to Figure 1 and Figure 2 for example. The shapes and sizes of the guide blocks 10 can be the same. The guide head 1 composed of the guide blocks 10 can be in the shape of a truncated cone, and the center of the guide head 1 is provided with a through hole through which the submarine cable 5 (the submarine cable 5 is described in Figure 3 ) passes. The cross section of each guide block 10 can be in the shape of a sector. After the guide blocks 10 are combined into the guide head 1, the cross section of the guide head 1 is in the shape of a ring. The first positioning assembly 20 and the second positioning assembly 21 can be detachably connected by bolts or studs.
[0043] Please refer to Figure 1 and Figure 2 for example. Optionally, the first positioning assembly 20 includes a first rubber pad 200 and a first body 201, the first rubber pad 200 is clamped between the first body 201 and the N guide blocks 10, and the first body 201 and the N guide blocks 10 are detachably connected. The first rubber pad 200 corresponds to the N guide blocks 10, so that the original first rubber pad 200 can be used to buffer the impact of the N guide blocks 10 on the first body 201, and there is no need to additionally manufacture the first rubber pad 200, thereby reducing the manufacturing cost of the first rubber pad 200. The first body 201 and the N guide blocks 10 can be detachably connected by the first fastener 3. The first rubber pad 200 is clamped between the left end of the first body 201 and the N guide blocks 10. Figure 2 The two guide blocks 10 above the middle can clamp the first rubber pad 200 with the first body 201.
[0044] Please refer to Figure 1 and Figure 2Optionally, the bottom surface of the guide block 10 has a diameter less than or equal to the diameter of the end surface of the first rubber pad 200. In this way, the N guide blocks 10 can be fully contacted after being combined (i.e., the bottom surface of the N guide blocks 10 after being combined does not have a suspended area) and the first rubber pad 200 can fully absorb the impact force received by the N guide blocks 10. The bottom surface of the guide block 10 can abut the left end surface of the first rubber pad 200. The outer diameter of the bottom surface of the guide block 10 can be less than or equal to the diameter of the left end surface of the first rubber pad 200.
[0045] Please refer to Figure 1 and Figure 2 Optionally, the submarine cable center clamp further comprises 2N first fasteners 3, each of the N guide blocks 10 corresponds to two first fasteners 3, and each first fastener 3 is detachably connected to the corresponding guide block 10 and the first body 201. In this way, each of the N guide blocks 10 can be prevented from rotating and being inconveniently combined with the adjacent guide block 10. The first fastener 3 can be a bolt or a stud and a nut thereof. The central axes of the first fasteners 3 can be arranged parallel to each other.
[0046] Please refer to Figure 1 and Figure 2 For example, Figure 2 When the number of the guide blocks 10 in the upper left is 2, the number of the first fasteners 3 can be 4. Each guide block 10 can be provided with two first mounting holes 100, and the first mounting holes 100 and the first fasteners 3 can be arranged one-to-one. The first fastener 3 can be arranged through the corresponding first mounting hole 100.
[0047] Please refer to Figure 1 and Figure 2 Optionally, each first fastener 3 is arranged through the first rubber pad 200. In this way, the first rubber pad 200 can be prevented from moving along the radial direction parallel to the first fastener 3, and the buffer area of the first rubber pad 200 corresponding to the guide block 10 can be prevented from moving.
[0048] Please refer to Figure 1 and Figure 2 Optionally, the second positioning assembly 21 comprises a second rubber pad 210 and a second body 211, the first body 201 and the second body 211 are detachably connected, the second rubber pad 210 is clamped between the second body 211 and the other N guide blocks 10, and the second body 211 and the other N guide blocks 10 are detachably connected. The second rubber pad 210 corresponds to the other N guide blocks 10, so that the impact of the other N guide blocks 10 on the second body 211 can be buffered by the original second rubber pad 210, and the second rubber pad 210 does not need to be additionally manufactured, thereby reducing the manufacturing cost of the second rubber pad 210. Figure 2The two guide blocks 10 at the lower side can sandwich the second rubber pad 210 with the second body 211.
[0049] Please refer to Figure 1 and Figure 2 , the specifications (including shape, size, and material, etc.) of the first rubber pad 200 and the second rubber pad 210 can be the same. The first rubber pad 200 and the second rubber pad 210 can be arranged above and below each other. The material of the first rubber pad 200 and the second rubber pad 210 can be nitrile rubber. The shape and size of the first body 201 and the second body 211 can be the same. The first body 201 and the second body 211 can be arranged above and below each other and detachably connected by bolts and their nuts. The first body 201 and the second body 211 are arranged apart from each other.
[0050] Please refer to Figure 1 and Figure 2 , the material of the guide block 10, the first body 201 and the second body 211 can be stainless steel. The second rubber pad 210 is sandwiched between the left end of the second body 211 and the other N guide blocks 10. The second body 211 and the other N guide blocks 10 can be detachably connected by the second fasteners 4.
[0051] Please refer to Figure 1 and Figure 2 , optionally, the diameter of the bottom surface of the guide block 10 is less than or equal to the diameter of the end surface of the second rubber pad 210. In this way, the other N guide blocks 10 can be fully in contact with the second rubber pad 210 after being spliced (i.e., there is no overhanging area on the bottom surface of the other N guide blocks 10 after being spliced), so that the impact force received by the other N guide blocks 10 can be fully absorbed by the second rubber pad 210. The bottom surface of the guide block 10 can abut against the left end surface of the second rubber pad 210. The outer diameter of the bottom surface of the guide block 10 can be less than or equal to the diameter of the left end surface of the second rubber pad 210.
[0052] Please refer to Figure 1 and Figure 2 , optionally, the submarine cable center clamp further comprises 2N second fasteners 4, each of the other N guide blocks 10 corresponds to two second fasteners 4, and each second fastener 4 detachably connects the corresponding guide block 10 and the second body 211. In this way, it can prevent each of the other N guide blocks 10 from rotating and being inconveniently spliced with the adjacent guide block 10. For example, Figure 2 When the number of guide blocks 10 at the lower side is 2, the number of second fasteners 4 can be 4.
[0053] Please refer to Figure 1 and Figure 2The second fasteners 4 can be bolts or studs and their nuts. The central axes of the second fasteners 4 can be parallel to each other. The specifications (shape, size or material) of the second fasteners 4 can be the same as those of the first fasteners 3. Each guide block 10 can include two second mounting holes 101, which can be arranged one-to-one with the second fasteners 4. The second fasteners 4 can be arranged in the corresponding second mounting holes 101.
[0054] Please refer to Figure 1 and Figure 2 Optionally, each second fastener 4 is arranged in the second rubber pad 210. In this way, the second rubber pad 210 can be prevented from moving along the radial direction parallel to the second fasteners 4, and the buffer area of the guide block 10 on the second rubber pad 210 can be prevented from moving.
[0055] In use, half of the guide blocks 10 can be fixed to the first positioning assembly 20 (for example, the two guide blocks 10 above in Figure 2 can be fixed to the first positioning assembly 20), and the other half of the guide blocks 10 can be fixed to the second positioning assembly 21 (for example, the two guide blocks 10 below in Figure 2 can be fixed to the second positioning assembly 21), and then the first positioning assembly 20 and the second positioning assembly 21 are fixed by bolts to clamp the submarine cable 5 (the submarine cable 5 is shown in Figure 3 , and the same below).
[0056] After the submarine cable center clamp is fixed to the submarine cable 5, the submarine cable 5 can be pulled, and finally the guide head 1 of the submarine cable center clamp is moved to abut against the J-shaped pipe of the booster station or the offshore wind turbine. The left end of the guide head 1 and the positioning assembly 2 is embedded in the J-shaped pipe. The first rubber pad 200 and the second rubber pad 210 can be in interference fit with the inner wall of the J-shaped pipe to complete the positioning of the submarine cable 5 in the J-shaped pipe by the positioning assembly 2.
[0057] The submarine cable center clamp provided by the embodiment of the present application is described in detail above. For those skilled in the art, the specific implementation and application range can be changed according to the idea of the embodiment of the present application. In conclusion, the content of the present application should not be understood as a limitation of the present application.
