Embodiment Construction

[0020] Such as figure 1 In the shown J-shaped tube protection device for offshore wind power submarine cables, a central positioning protection device 1 is installed on the submarine cable 5 at the tail section of the J-shaped tube 4, and the central positioning protection device 1 hugs the submarine cable 5 tightly, and Clamped in the J-shaped tube 4, the submarine cable 5 can be placed in the center of the J-shaped tube 4, preventing the submarine cable 5 from swinging and rubbing in the J-shaped tube 4, and a bending protection device is connected to the tail of the J-tube central positioning protection device 1 2. The bending protection device 2 is a joint occlusal structure, which can be formed into a chain by increasing the number of joints. The center of the bending protection device 2 is a through hole, which is used to pass through the submarine cable 5. The chain-shaped bending protection device 2 is designed with a certain The bending radius is not less than the saf...

Abstract

The invention discloses a device for protecting a J-shaped pipe out of an offshore wind power submarine cable. A centralized positioning protective device is arranged on the submarine cable at the tail of the J-shaped pipe, the submarine cable is tightly hugged by the centralized positioning protective device, and the centralized positioning protective device is clamped in the J-shaped pipe, so that the submarine cable is located at the central position of the J-shaped pipe; the tail of the positioning protective device is further connected with a bending protective device, the bending protective device adopts a joint occlusion structure, and a chain shape is formed by increasing the number of joints; a through hole is formed in the center of the bending protective device, and is used for penetrating through the submarine cable. According to the device, the protection of the submarine cable after coming out of the J-shaped pipe can be effectively solved, the submarine cable can be restricted to swing in the J-shaped pipe, overbending of the submarine cable in a suspension section is prevented, ocean current erosive wear as well as foreign object impact and anchoring damage are avoided, all of the installation is completed on a construction ship, the installation is simple, and in the construction aspect, later-stage maintenance is not needed after the installation is in place, so that the construction cost and later-stage maintenance cost are greatly reduced.

Description

technical field [0001] The invention relates to a protection device for a submarine cable exiting a J-shaped pipe of an offshore wind farm, in particular to a protection device for a submarine cable exiting a J-shaped pipe for an offshore wind farm. Background technique [0002] With the large-scale construction of offshore wind farms, submarine cables are the transmission medium of electric energy, and their safety and reliability are of paramount importance. In offshore wind farms, the submarine cable usually passes through the J-shaped tube fixed on the wind turbine pile foundation to the wind turbine base platform. In order to facilitate the construction of the submarine cable through the J-shaped tube, the inner diameter of the J-shaped tube is generally 2 times the outer diameter of the submarine cable. -2.5 times, and the transition section of the submarine cable from the tail of the J-shaped pipe to the contact with the seabed is in an arc-shaped suspension state, es...
