Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable protection equipment, in particular to a submarine cable protection device. Background Art

[0002] Under the influence of ocean currents and waves, submarine cables can trigger strong currents or high-speed vortices. These currents or vortices have a high scouring capacity, forming scour pits in a local area, causing the submarine cable to become suspended and prone to breakage. The prior art uses a U-shaped protective device. Two anti-sinking resistance baffles are installed on the inner side of the lower part of the protective shell body of this device. The resistance baffles divide the protective shell body into upper and lower parts, and a gap larger than the diameter of the submarine cable is formed between the two resistance baffles. The upper part of the protective shell body is provided with a water-permeable hole, and the lower ends of the protective shell body are provided with insertion portions for insertion into the seabed. The U-shaped baffle structure is subject to strong impact from the water flow and has poor water permeability. After prolonged scouring, the device is easily damaged. Patent document No. 202223210266.8 discloses a submarine cable protection device, which discloses multiple bases, each of which has a square groove on one side; multiple movable blocks, which are rotatably connected to the top of the base; and a support assembly, which is slidably connected to the inner wall of the square groove and is used to support the submarine cable.
