Description
Technical field
The utility model is related to a kind of marine wind electric field extra large cable and goes out j type protection of pipe device, more particularly, to coastal waters offshore wind farm
Field extra large cable goes out j type protection of pipe device.
Background technology
With the Large scale construction of marine wind electric field, as the transmission medium of electric energy, its security reliability is extremely for submarine cable
Close important.At sea in wind energy turbine set, extra large cable by being fixed on the j type pipe in blower fan pile foundation to base plate platform, is typically
It is easy to submarine cable operation and passes through j type pipe, the internal diameter of j type pipe is usually 2-2.5 times of extra large cable external diameter, and extra large cable is from j type pipe afterbody
Come out to and contact changeover portion with sea bed and be in arc vacant state, especially in coastal waters marine wind electric field, due to ocean current, gush, wave relatively
For violent, foundation pile four Charltons is formed washes away subsidence area, and under ocean current souring, subsidence area is increasing, thus leading to extra large cable
Hanging section is more and more longer, easily extra large cable overbending occurs, once extra large cable bending radius is less than its trouble free service radius, serviceability
To be affected, extra large cable, under long-term ocean current acts on, constantly can repeatedly swing, be susceptible to fatigue damage, due to j type simultaneously
Bore is much larger than extra large cable external diameter, extra large cable and j type pipe also can constantly grazing, also result in extra large cable external protection and wear and tear, finally break
Bad extra large cable serviceability.
For the problems referred to above, the method generally adopting at present has the normal form using jackstone or mixed mud bag of jettisoninging to fill
Foundation pile annex wash away subsidence area, but these method difficulty of construction are larger, and under the long-time souring of ocean current, building stones or
Person's mixed mud bag equally can be flushed away it is therefore desirable to again be filled reinforcing every a period of time, therefore totally relatively costly.Also
Have a kind of method be after j pipe plus one section of spheroidal graphite cast-iron protection pipe reinforced, this method to extra large cable excessively curved have certain
Protected effect, but do not account for that extra large cable is spacing in j type pipe, and cable remains able to arbitrarily swing in j type pipe, meeting and j
Type pipe grazing, the tube material of nodular cast iron protection simultaneously is cast iron, is very easy to corrosion in the seawater, once there is corrosion failure,
Just do not have protective effect, on the contrary because its weight is big, increase extra large cable and bear a heavy burden it is easier to lead to hanging section excessively curved.
Utility model content
, there is difficulty of construction greatly in utility model purpose: the utility model is directed to the safeguard measure going out j mouth of pipe extra large cable at present,
