Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable laying, in particular to a fixing structure suitable for submarine cable laying. Background Art

[0002] Submarine cables are cables wrapped in insulating materials and laid on the seabed, mainly used for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used in long-distance communication networks, such as between islands, cross-sea military facilities and other important occasions. They are an important part of the global communication network. However, submarine cables may be affected by objects such as seabed organisms, ship anchors, fishing gear, etc. during laying, causing damage to the cables. Fixed cables can reduce the damage caused by these external factors and improve the service life and safety of cables.

[0003] In the prior art, the submarine cable fixing structure is generally in direct contact with the submarine cable. In order to ensure the fixing effect of the fixing structure, the fixing structure is generally made of hard material. However, the hard contact between the fixing structure and the surface of the submarine cable may not provide sufficient buffering and stability, making the submarine cable easy to shake when subjected to external force, thereby increasing the risk of wear and breakage.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a fixing structure suitable for laying submarine cables, comprising a first casing 1, a second casing 2 is arranged on the left side of the first casing 1, a connecting component 5 is arranged between the first casing 1 and the second casing 2, the first casing 1 is connected to the second casing 2 through the connecting component 5, a submarine cable 3 is arranged in the first casing 1 and the second casing 2, a clamping component 4 is arranged in the first casing 1, and the first casing 1 fixes the submarine cable 3 through the clamping component 4.

[0024] The clamping assembly 4 includes two sets of pull rods 41 slidably arranged in the first sleeve 1, and the inner end surfaces of the pull rods 41 are all provided with clamping plates 42, and the inner end surfaces of the clamping plates 42 are all provided with rubber pads 43, and the rubber pads 43 are fitted with the submarine cable 3. The surfaces of the pull rods 41 in the first sleeve 1 are all wound with threaded blocks 44, and the outer end surfaces of the pull rods 41 are all threadedly connected with springs 45. The connecting assembly 5 includes an assembly groove 51 opened on the left side surface of the first sleeve 1, and an assembly ring 52 is slidably connected in the assembly groove 51. The assembly ring A second sleeve 2 is provided at the left end of 52, and movable bins 53 are symmetrically provided on the front and rear end surfaces of the second sleeve 2, and a rotating rod 54 is rotatably provided in the movable bin 53, and a torsion spring 55 is wound on the rotating rod 54 in the movable bin 53. Assembly blocks 56 are symmetrically provided on the front and rear end surfaces of the first sleeve 1 on the right side of the second sleeve 2, and the rotating rod 54 is slidably connected to the assembly block 56. A limit block 57 is provided on the surface of the rotating rod 54 on the right side of the assembly block 56, and a limit groove 58 is provided in the assembly block 56 on the left side of the limit block 57.

[0025] like Figure 2 As shown, one end of the threaded block 44 is welded to the inner wall of the first sleeve 1, and the other end of the threaded block 44 is welded to the surface of the clamping plate 42, which ensures the stability of the threaded block 44 when in use and prevents the threaded block 44 from sliding back and forth on the pull rod 41 and hitting the surface of the clamping plate 42 or the inner wall of the first sleeve 1 under the action of external force, thereby causing noise pollution.

[0026] like Figure 2 As shown, the outer wall of the spring 45 is provided with anti-slip grooves, and the surface of the pull rod 41 is provided with external threads that screw into the threads on the inner wall of the spring 45, thereby ensuring the stability of the spring 45 when in use and preventing the threads between the spring 45 and the pull rod 41 from being too tight, which may cause the staff to slip when turning the spring 45, making it difficult for the staff to operate the spring 45.

[0027] like Figure 4 As shown, the torsion spring 55 is wound around the middle surface of a part of the rotating rod 54, and both ends of the torsion spring 55 are welded to the inner wall of the movable bin 53, which ensures that the restoring force output by the torsion spring 55 on the two ends of the rotating rod 54 is relatively uniform, and prevents the torsion spring 55 from driving the rotating rod 54 to rotate in the movable bin 53. The uneven force on the two ends of the rotating rod 54 prevents the rotating rod 54 from being easily shaken when rotating in the movable bin 53, thereby affecting the stability of the connection between the limit block 57 and the assembly block 56.

[0028] like Figure 4As shown, two groups of limit blocks 57 are arranged on the outer wall of the rotating rod 54. Both groups of limit blocks 57 are designed in a rectangular shape. The limit blocks 57 are adapted to the limit grooves 58.

As a result, it is more laborious for the staff to align the limit blocks 57 with the limit grooves 58, which is not convenient for the staff to quickly connect or disassemble the first sleeve 1 and the second sleeve 2.

[0029] The use method and working principle of the device: When the submarine cable 3 needs to be fixed, first pull the pull rod 41 in the direction away from the first casing 1, so that the pull rod 41 slides in the first casing 1 and drives the clamping plate 42 to move, then place the submarine cable 3 between the two groups of rubber pads 43, then loosen the pull rod 41, use the restoring force of the threaded block 44 to push the pull rod 41 to slide in the first casing 1, and make the two groups of rubber pads 43 clamp the submarine cable 3, then turn the spring 45, so that the spring 45 is threaded on the pull rod 41 and rotated to fit the surface of the first casing 1, so that the spring 45 adjusts the pull rod 41 and the inner wall of the first casing 1 to the threaded block 44, when the second sleeve 2 needs to be installed, the limit block 57 is rotated to align with the limit groove 58, and then the assembly ring 52 on the second sleeve 2 is inserted into the assembly groove 51, and the second sleeve 2 synchronously drives the rotating rod 54 and the limit block 57 to pass through the limit groove 58 and the assembly block 56 until the second sleeve 2 is in contact with the outer wall of the first sleeve 1. At this time, the left surface of the limit block 57 is in contact with the right surface of the assembly block 56, and then the rotating rod 54 is released, and the restoring force of the torsion spring 55 is used to drive the rotating rod 54 to return and rotate in the movable bin 53, and the limit block 57 is misaligned with the limit groove 58, so as to achieve the purpose of installing the first sleeve 1.
