Description
Technical field
The utility model belongs to the cable fixture of offshore platform cathodic protector, and especially the strong magnetic stuck-module of ocean platform cathodic protector cable, protect the cable of cathodic protector injury-free.
Background technology
According to the code requirement of present current condition and China Classification Society, marine all drilling well and operation jack-up units with spud leg all must be installed a cover cathodic protector, and shoe, spud leg are carried out anti-corrosion protection.This device generally is arranged on the inside of platform pile shoe, spud leg, is a kind ofly to have the assurance platform of stopping property not by the extremely important and requisite impressed current catholic protection device of sea-water corrosion.
Impressed current catholic protection device mainly is comprised of potentiostat, supplementary anode and reference electrode.Potentiostat is the control center of impressed current catholic protection device, and the alternating-current inversion that provides by platform self provides protective current for direct current for protector, and it generally is arranged on power distribution station.The material of supplementary anode mainly contains platinum-silver alloys, platinum composite anode and titanium-based metal oxide compound etc.; it is the additional electrodes of this device; generally be arranged on spud leg inside; it is connected with the positive pole of potentiostat power supply by its outer transmission cable, and its effect is to make electric current be transmitted to protected body from electrode through cable----
-The surface of-shoe, spud leg; The main raw of reference electrode mainly contains zinc alloy, high purity zinc, silver, silver chloride etc., also is arranged on spud leg inside, is used for measuring protected body--
-The current potential of-shoe, spud leg to Controlling System-potentiostat transmission of signal, in order to regulate the protective current size, makes the current potential of structure be in given range by transmission cable.Be connected with supplementary anode, reference electrode by cable after the potentiostat energising, play through a series of electrification adjustings the effect that protecting platform is avoided galvanic etching.
Two split conductor cables of the cathodic protector of ocean platform spud leg are to the guard electrode conduction that is arranged on shoe inside, regulate protective current; these two cables can be described as the nervus centralis of whole cathodic protector; its quality directly has influence on whole platform pile shoe, spud leg tolerate corrosion in seawater life-span; thereby determining the work-ing life of bed rearrangement platform, playing a part very crucial.The lifting technology of considering spud leg requires and sealing requirements; the cable that supplementary anode in shoe and reference electrode are drawn must be guided to the spud leg top by the spud leg inner hollow, the top is fixing process after again along the spud leg top along under guide on the transfer link box of cathodic protector at wedge bracket edge.So, be quite necessary to the protection of exposed cable externally.
In order to protect this two split conductor cables, Adopts measure is to draw down a wireline that diameter is suitable with cable after fixing at the spud leg top again now, then is in the same place with cable tie, protects cable, strengthens the work-ing life of cable.But because spud leg is higher, generally between 50 meters-80 meters, and that the platform main deck generally can not rise is so high.Therefore, the cathodic protection cable that extracts from spud leg can remain 20-
50Rice does not wait, exposed outer rim at spud leg.If it is infeasible taking on spud leg the fixing mode of weldering something that gives the game away, because coordinate needs according to lifting platform, the spud leg outside has not allowed above any foreign matter is welded on, in order to avoid affect lifting, so cable can't be fixed on spud leg.And many due to sea turn, wind is large, the strong wind cable that can flicker causes cable and spud leg friction, can make cable be damaged or rub when serious, causes cable and spud leg short circuit, the galvanic protection circuit malfunction, thereby cause platform leg to suffer the serious consequence of sea-water corrosion.The production scene be badly in need of a kind of device can protect cable not wind-engaging flicker impairedly, it is fixed on spud leg, do not affect again the lifting of platform simultaneously.
Summary of the invention
The purpose of this utility model designs the strong magnetic stuck-module of ocean platform cathodic protector cable exactly; make itself have the protecting platform impressed current catholic protection device cable not wind-engaging flicker impaired; make again it be fixed on function on spud leg, solve the cable fixation problem of cathodic protector on marine all production platforms.
Technical solution of the present utility model is:
The strong magnetic stuck-module of ocean platform cathodic protector cable comprises solid magnetosheath, core iron, magnetic isolated body, magnet steel and cable fixed plate, Gu magnetosheath and cable fixedly pellet be one-piece construction, by base plate with shell and cable fixedly between pellet at closed bottom; Fixedly between pellet, ecto-entad is equipped with core iron, magnetic isolated body and magnet steel successively at the shell of solid magnetosheath and cable; Cable fixedly pellet is provided with cable trough and fixed bolt hole, by cable fixed plate and standing bolt, cable is fixed in cable trough.
The strong magnetic stuck-module of ocean platform cathodic protector cable comprises solid magnetosheath, core iron, magnetic isolated body and magnet steel, Gu magnetosheath and cable fixedly pellet are Split type structures, Gu magnetosheath is provided with shell and base plate, base plate is provided with cable and passes through the hole, base plate and shell are welded together, with cable fixedly pellet be placed in shell; The shell of solid magnetosheath and cable fixedly between pellet ecto-entad core iron, magnetic isolated body and magnet steel are housed successively; Cable fixedly pellet is provided with cable trough and fixed bolt hole, and on the header board of shell, correspondence arranges fixed bolt hole, by standing bolt with cable fixedly pellet fix, cable is fixed in cable trough.
The beneficial effects of the utility model are: 1, the utility model is owing to there being the magnet steel of strong magnetic material in solid magnetosheath, and cable is tightened to one with solid magnetosheath, and the cable of platform cathodic protector is absorbed and fixed on the convex surface of spud leg.During lifting platform, this device is together taken off together with cable, after lifting is completed, absorption installation again, do not affect the lifting of bed rearrangement platform; 2, because the cable fixed plate of this device can be dismantled, therefore, can be according to actual needs and field condition, adjust the position of the cable that is fixed; 3, effectively avoid the cable of cathodic protector to be subjected to the sea wind impaired present situation of flickering, extended the work-ing life of cathodic protector, thereby made the bed rearrangement ocean platform avoid sea-water corrosion, extended the work-ing life of platform, had obvious economic benefit.
