Problems solved by technology

This operation greatly increases the working time at sea, and after installation, the submarine cable can only be fixed at a specific position and cannot move up and down
The existing center positioning device is generally fixed to the submarine cable through friction force. During the traction and laying of the submarine cable, if the installation torque is not in place or encounters ocean current impact and other resistance on the seabed, it is prone to slipping.
Existing conventional J-tubes are generally made of carbon steel, and the lower end and bottom section of the J-tube are usually in seawater immersion or seawater splashing areas. In the above two cases, seawater and underwater microorganisms will cause serious damage to the J-tube. corrosion

Embodiment Construction

[0023] Such as figure 1 and figure 2 As shown, an integral submarine cable protection device of the present invention is installed in combination with a platform 1 and a base 2, the platform 1 is installed on the base 2, the base 2 is installed on the seabed surface 4, and the base 2 extends out of the sea level. The platform 1 is located above the sea level, and the platform 1 is higher than the seawater splash zone. The integrated submarine cable protection device includes an I-shaped tube 10 and several flexible protective tubes 20, the I-shaped tube 10 is attached to the base 2, and the top of the I-shaped tube 10 is docked with the platform 1, The bottom end of the I-shaped pipe 10 is connected to a flexible protection pipe 20 , and the flexible protection pipe 20 is connected end to end in turn, and extended to the seabed 4 . The submarine cable 3 passes through the I-shaped pipe 10 and several flexible protection pipes 20 , and the submarine cable 3 passes through th...

Abstract

The invention discloses an integrated submarine cable protection device. The device is installed in combination with the platform and the base, the platform is mounted on the base, the base is installed on a seabed surface, the integrated submarine cable protection device comprises a plurality of I-shaped pipes and a plurality of flexible protection pipes, the I-shaped pipes are attached to the base, the top ends of the I-shaped pipes are in butt joint with the platform, the flexible protection pipes are connected with the bottom ends of the I-shaped pipes, and the flexible protection pipes are sequentially connected end to end and extend to be laid on the seabed surface, and the flexible protection pipes at the joint of the base and the seabed surface are bent. The integrated structure isgood in fatigue resistance and bending resistance, so that the submarine cable can be protected more effectively; the flexible protection pipe made of a composite material is good in seawater corrosion resistance and longer in service life; installation is simple and rapid, and rapid laying of submarine cables is facilitated.

Description

technical field [0001] The invention relates to the technical field of submarine cable protection devices, and more precisely relates to an integral submarine cable protection device. Background technique [0002] With the development of offshore wind power and offshore oil and gas, the application of submarine cables is gradually increasing. In order to ensure the normal operation of submarine cables, it is necessary to install protective devices outside the submarine cables. Submarine cables pass through a number of different environmental areas from the platform to the seabed. The prior art submarine cable protection devices usually have different structures for these different environmental areas. The complex structure and installation process are very troublesome. At present, during the laying process of submarine cables, it is often necessary to use J-shaped tubes for protection. The distance from the bottom of the existing J-shaped pipe to the seabed is generally 1.5...
