[0002] With the continuous strengthening of China's development efforts for marine renewable energy, especially the rapid development in the field of offshore wind power, submarine cables have been more and more widely used. Therefore, it is particularly important to ensure the safe operation of submarine cables both on land and in deep-sea bottoms, and effective protection measures must be taken to prevent natural or man-made damage to submarine cables. Content of the Utility Model

[0003] The purpose of the utility model is to provide a wear-resistant protection device for submarine cables.

[0004] The utility model provides the following technical solutions:

[0005] The utility model provides a wear-resistant protection device for submarine cables, including a pair of protective pipe half tiles that can be fitted together to form a cylinder. A semi-circular connecting head is arranged at the head end of the protective pipe half tile, and a semi-circular clamping sleeve that cooperates with the semi-circular connecting head is arranged at the tail end of the protective pipe half tile. A connecting component for fixing the pair of protective pipe half tiles is arranged on the protective pipe half tile, and a wear-resistant sleeve for protecting the pair of protective pipe half tiles is also sleeved on the pair of protective pipe half tiles.

[0006] Further, the connecting component includes screw fixing seats correspondingly arranged on the protective pipe half tiles and locked and fixed by screws.

[0007] Further, there are four groups of the screw fixing seats.

[0008] Further, the wear-resistant sleeve includes a pair of semi-cylindrical pipes that can be fitted together to form a cylinder. Card slots are arranged on the side walls at both ends of the semi-cylindrical pipes, and a tightening card band for binding the pair of semi-cylindrical pipes into a cylinder is arranged in the card slots.

[0009] Further, the semi-circular connecting head is provided with a semi-circular opening for the semi-circular clamping sleeve to be embedded.

[0010] Compared with the prior art, a wear-resistant protection device for submarine cables provided by the utility model has a simple structure, is convenient to connect and install, can be repaired and replaced, and has good practicability and economy. The half-watt of the protection tube is fixed outside the cable to be protected through screws. Relying on the cooperation of the semi-circular connecting head and the semi-circular clamping sleeve, multiple devices can be cooperated with each other. The tightening strap tightly fastens the wear-resistant sleeve outside the half-watt of the protection tube, making the external wear-resistant performance of the device better on a harder seabed, stable and reliable in long-term use. At the same time, the externally tightened wear-resistant sleeve is also beneficial to strengthening the protection of the device against external falling objects, making the half-watt of the protection tube more firmly sleeved outside the cable.
