Description
Technical field
The present invention relates to ocean engineering fields, more particularly, to a kind of protective device of underwater cable.
Background technique
Increasingly increase with China to energy demand is also rapidly adding the exploitation dynamics of marine oil and gas, offshore wind farm
Greatly.Important medium of the underwater cables such as submarine cable, dynamic cable, umbilical cables as power transmission, signal control, pressure conduction etc.,
Security reliability in use is most important.Underwater cable used in oil platform or offshore wind power platform is usually
It is worn from seabed to platform by rigid pillar, for smooth poling, the internal diameter of rigid pillar is usually the 3 of underwater cable outer diameter
Times or so, and be in bell shape in bottom inlet port part.Due to the size characteristics between rigid pillar and underwater cable, installation
Underwater cable can freely swing in rigid pillar afterwards, especially the exit in the lower end of rigid pillar, and underwater cable is by ocean at this
Stream influence is the most violent, can not stop under ocean current effect dynamic, while constantly colliding rigid pillar, is easy to make under long duration of action
At the endurance failure of underwater cable, the normal use of entire platform is influenced；In addition, since the lower port of rigid pillar is immersed in seawater
In, therefore seawater can enter rigid pillar, while the marine growths such as some shellfishes can be attached to the inner wall of rigid pillar and underwater
The outer layer of cable, and can climb up along rigid pillar and underwater cable, and seawater and marine growth can be to underwater cables and rigid pillar
It causes to corrode, reduces its service life.In order to ensure safety and reliability of underwater cable during prolonged use, such as
What, which effectively promotes its service life, becomes particularly important.
Conventional method is protective device of the tail portion installation of cable under water for centralized positioning and sealing at present, by this
Protective device holds underwater cable tightly, and is stuck in the straight pipe of rigid pillar, so that underwater cable is in the center of rigid pillar, separately
Outside in order to guarantee that underwater cable will not be damaged because of overbending, bending restrictor usually can be also set on the protection device.
The fixation of entire protective device relies primarily on the sealing ring being stuck in the straight pipe of rigid pillar and clamps the frictional force of underwater cable
Effect, sealing ring can occur aging frictional force is reduced after a period of time, protect so as to cause protective device and rigidity
Crystallized ability between pipe weakens, while being limited by the requirement of installation, and underwater cable is not tight inside rigid pillar, and
Due to the reduction of the frictional force of fixing seal ring, entire protective device will deviate from the installation site set originally, if underwater cable is loose
Relax it is more especially in deepwater regions, entire protective device may be detached from away from the end horn mouth of rigid pillar, once fill
Protection to underwater cable will be lost by setting abjection, and the bending load of the underwater cable outside horn mouth is caused to increase, bending restrictor
It can not also play here and effectively be bent restriction effect, cannot repair in time will be so that underwater cable premature breakdown, be caused serious
Loss, and re-start installation or reprocess and will also bring huge construction cost and security risk.
