Description
Technical field
The present invention relates to a kind of sea cable centralized positioning protection device, be applied to the field such as oil platform, wind-powered electricity generation sea cable, it is made
With being to protect sea cable, the centralized positioning in protection pipe of the sea cable and traction etc..
Background technology
Marine cable is the wire by wrapped with insulation, be laid on seabed in order to set up between country and country, island
And between inland, between oil platform and inland, the important communication equipment in the place such as military installations over strait.Along with China is to the energy
Demand increases day by day, and the dynamics of marine oil and gas, offshore wind farm exploitation the most rapidly strengthens.The important matchmaker that sea cable transmits as electric power
Being situated between, security reliability in use is most important.Oil platform or offshore wind farm marine sea cable are to be protected by rigidity
Pipe is worn above platform from seabed, smooth for poling, and sea cable pillar internal diameter is usually about 3 times of sea cable external diameter.Therefore sea cable
Can freely swing in pillar, particularly in exit, pillar lower end, at this, cable feeling the current in sea is the most violent, at ocean current
Can not stop under Zuo Yong dynamic, constantly collide pillar simultaneously, the endurance failure of cable can be caused under long duration of action, cause cable
Cannot transmit electricity, ultimately result in whole power system paralysis, thus cause huge economic loss.
The most conventional guard method is to utilize weight to push down going out pillar sea cable, stops sea cable to move, and the method can
Having the movement controlling sea cable in short time, but under long-term ocean current effect, weight can be flushed away, sea cable can arbitrarily be put again
Dynamic.Therefore exploitation one is capable of sea cable centralized positioning in pillar, and the device stoping sea cable arbitrarily to swing in pillar is outstanding
For important.
Summary of the invention
The invention aims to solve deficiency of the prior art, it is provided that one can be pillar lower port section sea cable
It is limited in pillar center, effectively controls sea cable and swing in pillar, prevent from producing collision with rigidity pillar, it is to avoid sea cable exists
Endurance failure occurs under the long term of ocean current, and simple in construction, easy for installation, reliability is high, in the extra large cable of service life length
Heart positioning protection device.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of sea cable centralized positioning

Hole, also include bolt, described bolt be arranged in the dormant bolt hole that symmetry is offered by two halves transition connecting apparatus pretension in
One overall transition connecting apparatus.
In a preferred embodiment of the present invention, the described cross section crossing attachment means and flange is circular configuration.
In a preferred embodiment of the present invention, the described diameter crossing attachment means is less than the diameter of flange.
In a preferred embodiment of the present invention, described flange is provided with multiple evenly distributed bolt hole.
In a preferred embodiment of the present invention, the diameter of described centre bore is more than the external diameter of sea cable.
In a preferred embodiment of the present invention, the described outer surface crossing attachment means is coated with corrosion-inhibiting coating.
The invention has the beneficial effects as follows: a kind of sea cable centralized positioning protection device of the present invention, it is possible to sea cable bending limit
Device processed couples together with J-type pipe, it is possible to sea cable is limited in J-type pipeline center position, can be effectively protected sea cable and make it avoid
The collision of rigidity, impacting and be conducive to the traction of sea cable, it has simple in construction, intensity is high, corrosion-resistant, easy for installation, make
By advantages such as year limits for length.
