[0028] The utility model provides Figure 1 A submarine cable pipeline repair device shown includes a fixing mechanism 1 and further includes:

[0029] There are two limiting mechanisms 2 , which are respectively arranged on the outer walls at both ends of the fixing mechanism 1 , and are used to pull and limit the fixing mechanism 1 .

[0030] In order to conveniently fix the submarine cable pipeline, Figure 2 and Figure 4As shown, the fixing mechanism 1 includes two first clamping plates 101, and a second clamping plate 102 is rotatably installed on one side of the two first clamping plates 101. A connecting bolt 103 is arranged between the side of the second clamping plate 102 away from the first clamping plate 101 and the adjacent first clamping plate 101. The first clamping plate 101 and the second clamping plate 102 can be connected by the connecting bolt 103, so that the fixing mechanism 1 can be stably fixed to the outside of the submarine cable pipeline.

[0031] In order to enable the fixing mechanism 1 to stably connect and reinforce the broken part of the submarine cable pipeline, Figure 2-3 and Figure 5 As shown, the limiting mechanism 2 includes two traction springs 201, and the two traction springs 201 at the same end are respectively arranged on the inner walls of the two first clamps 101 or the second clamps 102 at the same end. A connecting plate 203 is arranged at one end of the two traction springs 201 at the same end away from the inner wall of the first clamp 101 or the second clamp 102. Fastening pins 204 are arranged between the top and bottom of the connecting plate 203 and the inner walls of the adjacent first clamp 101 or the second clamp 102. The connecting plate 203 can pull and limit the first clamp 101 or the second clamp 102 at the same end, so that the device can stably connect and fix the broken part of the submarine cable pipeline.

[0032] In order to stably connect the first clamping plate 101 and the second clamping plate 102, as shown in FIG. Figure 2-5 As shown, the fixing mechanism 1 includes a movable groove 104, and the movable grooves 104 are provided with four. The four movable grooves 104 are respectively opened on the outer walls of the two first clamping plates 101 and the two second clamping plates 102. The inner wall of the movable groove 104 is fixedly connected to the adjacent traction spring 201. The top and bottom of the inner side of the connecting plate 203 are fixedly installed with a slider 202. The slider 202 is fixedly connected to the end of the adjacent traction spring 201 away from the inner wall of the movable groove 104. The outer wall of the slider 202 is fixedly connected to the adjacent movable spring 201. The inner wall of the groove 104 is movably connected, and the inner wall of the movable groove 104 is threadedly connected to the adjacent fastening pin 204. The end of the fastening pin 204 away from the inner wall of the movable groove 104 is abutted and connected to the adjacent slider 202. The fastening pin 204 is movably inserted into the inner side of the adjacent traction spring 201. The two first clamps 101 or the second clamps 102 at the same end move along the outer wall of the slider 202 through the movable groove 104, and the distance between the two first clamps 101 or the second clamps 102 at the same end can be adjusted.

[0033] In order to prevent the first clamping plate 101 and the second clamping plate 102 from causing wear to the submarine cable pipeline, Figure 2 and Figure 4As shown, the fixing mechanism 1 includes a protective pad 105, and four protective pads 105 are provided. The four protective pads 105 are respectively fixedly installed on the inner sides of the two first clamps 101 and the two second clamps 102. The cross-section of the protective pad 105 viewed from above is arranged in a fan-shaped structure. The protective pad 105 is arranged as a silicone rubber material component. The protective pad 105 can protect the contact between the first clamp 101 and the second clamp 102 and the submarine cable pipeline, and can prevent the first clamp 101 and the second clamp 102 from causing wear to the outer wall of the submarine cable pipeline.

[0034] In order to make the device easy to move outside the submarine cable duct, such as Figure 2 and Figure 5 As shown, the front vertical section of the connecting plate 203 is set as a C-shaped structure, and the top cross section of the connecting plate 203 is set as a fan-shaped structure. Through the setting of the connecting plate 203, the device can be easily moved at the outer corner of the submarine cable pipeline, and the distance between the two first clamping plates 101 and the second clamping plates 102 at the same end can be easily adjusted.

[0035] The specific implementation method is as follows: when repairing the broken part of the submarine cable pipeline, the two first clamping plates 101 and the second clamping plates 102 are pulled toward the top and the bottom as needed, so that the movable groove 104 can move along the outer wall of the adjacent slider 202, thereby causing the adjacent traction spring 201 to contract. When the first clamping plates 101 and the second clamping plates 102 are adjusted to a suitable position, a fastening pin 204 is used to penetrate the inner wall of the movable groove 104 and abut against the adjacent slider 202, so that the adjusted first clamping plates 101 and the second clamping plates 102 can remain stable, and then the second clamping plate 102 is rotated to open the gap between it and the first clamping plate 101, and then it is sleeved onto the outside of the broken part of the submarine cable pipeline, so that the top first clamping plates 101 and the second clamping plates 102 are at the top of the broken part, and the bottom first clamping plates 101 and the second clamping plates 102 are at the top of the broken part. The first clamping plate 101 and the second clamping plate 102 are at the bottom of the fracture, and then the connecting bolts 103 can be used to connect and fix the opening sides of the first clamping plate 101 and the second clamping plate 102, so that the first clamping plate 101 and the second clamping plate 102 can be stably sleeved onto the outside of the submarine cable pipe, and at the same time, the protective pad 105 of the silicone rubber material component can buffer and protect the connection between the first clamping plate 101 and the second clamping plate 102 and the outer wall of the submarine cable pipe, which can avoid the first clamping plate 101 and the second clamping plate 102 from causing wear to the outer wall of the pipe, and then the fracture of the submarine cable pipe can be repaired conveniently, and the submarine cable pipe can be prevented from causing compression and damage to the submarine cable. This implementation specifically solves the problem in the prior art that the submarine cable pipe is prone to compression on the submarine cable after it is broken, which will affect the working state of the submarine cable.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
