Description
Technical field
The present invention relates to a kind of extra large cable centralized positioning protection device, is applied to oil platform, sea more particularly to one kind
The wind-powered electricity generation extra large cable extra large cable centralized positioning protection device that centralized positioning is protected in pillar.
Background technology
International extra large cable, also known as international seabed communication cable, it is the wire with wrapped with insulation, is laid on seabed, to
Set up the telecommunication transmission between country.Submarine communication cable be mainly used in long range communication network, be generally used for remote island it
Between, the more important occasion such as military installations over strait.Sea electric power cable lays distance compared with communication cable compared to much shorter is wanted, mainly
For between the island of land, cross rivers or bay, from interconnection between land connection drilling platforms or drilling platforms etc..General
In the case of, it is undoubtedly more expensive than the aerial cable of same length to transmit electric energy using submarine cable, but with it often than with small and
Isolated power station make provincialism generate electricity it is more economical, offshore area using benefit it is more.In the more country in island and river,
Such a cable application is wide.Compared with overland cable, first, laying does not need sap or supported with support, thus invest
Few, construction speed is fast；Second, in addition to landing sector, cable is mostly in the seabed of certain depth, not by the natural ring such as stormy waves
The destruction in border and the interference of human production activity, so, cable safety and stability, strong antijamming capability, security performance is good.
As China increasingly increases energy demand, marine oil and gas, the dynamics of offshore wind farm exploitation also rapidly increase.Extra large cable
It is most important as the important medium of power transmission, security reliability in use.Oil platform or offshore wind farm
Marine extra large cable is to be worn by rigid pillar from seabed to above platform, is that poling is smooth, extra large cable pillar internal diameter is usually outside extra large cable
3 times or so of footpath.Therefore extra large cable can freely swing in pillar, and particularly in pillar lower end exit, extra large cable is by ocean current at this
Influence is the most violent, can not be stopped under ocean current effect dynamic, while constantly collides pillar, and cable can be caused under long duration of action
Endurance failure, cause cable not transmit electricity, whole power system paralysis is ultimately resulted in, so as to cause huge economic loss.Mesh
Preceding conventional guard method is to be pushed down using weight pillar extra large cable is gone out, and prevents extra large cable from moving, this method can have in the short time
The movement of effect control extra large cable, but under the effect of long-term ocean current, weight can be flushed away, the enough any swings of extra large cable and can.Therefore open
Hair one kind can realize extra large cable centralized positioning in pillar, and the device for preventing extra large cable from arbitrarily being swung in pillar is particularly important.
The content of the invention
Goal of the invention：The invention aims to solve deficiency of the prior art, there is provided one kind can be under pillar
Segment port extra large cable is limited in pillar center, effectively controls extra large cable to be swung in pillar, prevents from producing collision with rigid pillar,
Avoid extra large cable that endurance failure occurs under the long term of ocean current, simple in construction, easy for installation, reliability is high, service life
Long extra large cable centralized positioning protection device.

Interior, the fixture is internally provided with centre bore B；The symmetrical two sides of fixture offer bolt hole B, symmetrical two parts of fixture
Half cylindrical structure pass through the bolt connection in bolt hole B；
The fixture symmetrically has installation gap between two-part half cylindrical structure.
Further, the material of the housing and fixture is high intensity, the high molecular polymer of seawater corrosion resistance.
Further, the maximum outside diameter of the centre bore B is less than centre bore A external diameter.
Further, the external diameter of the installation groove is more than centre bore A external diameter.
Beneficial effect：The housing of the present invention and this Ha Fushi symmetrical structures of fixture are easily installed, housing head taper
Structure design, it is easy to penetrate pillar；The installation convex design of afterbody, extra large cable bend protection device can be connected；Fixture symmetrical two
There is the design in installation gap between partial half cylindrical structure, provided to fixture and be pressed against space, ensure clamp sea
Cable.The material for making this extra large cable centralized positioning protection device simultaneously is high molecular polymer, has intensity height, resistance to corrosion seawater
The advantages of the advantages of energy is good, density is small, is easy to construct, and reliability is high, and service life is long.The extra large cable centralized positioning protection of the present invention
Device can hold extra large cable tightly, while inlay card realizes centralized positioning of the extra large cable in pillar, can avoid extra large cable in pillar in pillar
It is interior arbitrarily swing and collided with pillar caused by endurance failure, improve extra large cable security reliability in use, tie simultaneously
Structure is simple, easy for installation, without diver's underwater operation.
