The main considerations are the submarine channel conditions and sea surface environment conditions when the cables are laid. Unlike cables buried in the deep sea, shallow submarine cables are easily damaged by trawlers, anchors, sharks and other marine life.

[0004] However, the existing long-length submarine power cables also need to consider whether the cable intermediate joint technology is reliable. The outer end of the cable intermediate joint and the cable adhesion part are prone to aging and loosening after being hit by foreign objects. After the submarine power cable is damaged, it is inconvenient for maintenance personnel to find the damaged section in a dim light environment after diving. Based on the above, a submarine cable bracket for indicating the faulty section is now needed, so that power maintenance personnel can quickly identify and find the faulty and damaged section of the cable.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and defects, and a submarine cable bracket for indicating the fault section is provided, in order to achieve a more practical purpose. Summary of the invention

[0019] In addition, by providing a base frame and by screwing the limit screw laterally into the threaded hole, the limit screw can be inserted into the butt tube and the plug rod, so that the base frame and the top frame can be connected and fixed, and the base frame and the top frame can be supported on the outside of the adjacent cable connection, thereby preventing external ships or marine life from touching the cable connector and causing the connector to loosen.

[0020] In addition, by setting a fixing hoop and fixing it at the side end of the sealing layer through two sets of fixing hoops, the outer edge of the sealing layer can be protected, the sealing layer can be prevented from loosening due to foreign objects touching it, and water can be prevented from entering the flange pipe.

[0021] In addition, by providing a sealing layer and fixing the outside of the cable body with two sets of fixing hoops, and by limiting and fitting the outer end facade of the sealing layer with the inner facade of the fixing hoops, the relative position of the frame formed by the bottom frame and the top frame and the circuit connection end can be limited, thereby preventing the protective frame and the circuit connection end from being dislocated due to external water flow.

[0022] In addition, by setting up a top frame, when maintenance personnel replace the cable in the faulty section, the user can pull the pull rope to reset the sliding column, and the fixing hoop and the hoop plate can be easily separated.
