Abstract
The utility model discloses a device for fixing and protecting submarine cables landing a platform along a marine steel structure pile leg after coming out of submarine cable trenches, suitable for various fixing and protecting places for submarine cables landing a platform after coming out of submarine cable trenches. The fixing and protecting device is composed of a self-sinking anchor-intimating member, a 90-degree connecting flange and an anticorrosion metal flexible pipe, bare submarine cables between the fixing fasteners of platform pile leg metal submarine cable protecting pipes after coming out of submarine cable trenches are entirely sealed and protected by connecting bolts, so that the service life of the submarine cables are greatly extended, ensuring the reliability and security of power consumption in offshore oil exploration.
Description
Technical field
The utility model relates to fixedly protection field of submarine cable; Be exactly a kind of submarine cable coastal device of fixing protection submarine cable when going up steel structures spud leg and landing platform after Hai Langou goes out ditch specifically, be applicable to the various use submarine cables fixedly protection place when landing platform behind the cable ditch of going to sea.
Background technology
The employed power electricity consumption overwhelming majority is through submarine cable, with power delivery on each oil exploitation platform or the job platform through land transformer station in the offshore oil exploration and development., submarine cable at first submarine cable is carried out the protection insulation work that submarine cable is gone into Hai Chu after the overland cable ditch causes sea wall when laying; Lay the trench driving device excavation submarine cable ditch of boats and ships then with the submarine cable special use; Again submarine cable is laid in to tunnel in the submarine cable ditch of opening subsequently and buries; When submarine cable lays when platform is landed in the offshore oil platform vicinity, need submarine cable after Hai Langou goes out ditch, to go upward to the offshore oil platform spud leg in advance, and then land the switchgear house of platform along spud leg with certain angle.Just produce such problem this moment: the submarine cable cable ditch that when stepping on platform, need go to sea in advance, can guarantee that just it lands the switchgear house of platform at a certain angle along spud leg.Since the extra large cable of this section expose fully in seawater and with certain fixed angle on the oil platform spud leg.Like this at ocean current, surge, be in swing state for a long time under the influence of strong wind, to the very big influence that produces in useful life of submarine cable.According to incompletely statistics, 60% has direct or indirect reason with the problems referred to above in the fault of in China's offshore oil exploitation, using at present that submarine cable took place.
At present; The scheme that overcomes the above problems is following: when submarine cable lays when platform is landed in the offshore oil platform vicinity; Submarine cable carries out ballast to play the fixedly effect of submarine cable from going out trench with sandbag at submarine cable after Hai Langou goes out ditch in advance, goes out submarine cable behind the ditch lands platform again along platform leg with certain angle switchgear house thereafter.In order to solve the problem of submarine cable and platform leg fixation clamp wearing and tearing submarine cable fixedly the time, generally adopted " horn mouth " formula fixation clamp to reduce the wearing and tearing between submarine cable and the fixation clamp.But because go to sea behind the cable ditch and this section submarine cable between the platform leg fixation clamp all the time with certain angle unsettled with seawater in; Therefore this scheme has just played the wearing and tearing of alleviation submarine cable, and does not fundamentally solve the problem of protection submarine cable.Before the utility model design is accomplished, do not see the submarine cable water outlet fixing protector identical and in daily production, use with the utility model structure, do not see the device identical and sell with the utility model structure.
Summary of the invention
The purpose of the utility model is to provide a kind of submarine cable fixing protector behind the cable ditch that goes to sea, and has fundamentally solved behind the cable ditch that goes to sea in advance and the unsettled unguarded problem of this section submarine cable between the platform leg fixation clamp after practical this fixture.Also solved former submarine cable simultaneously and after Hai Langou goes out ditch, fixedly gone out the unstable problem of Gou Chuhai cable in advance with the sandbag ballast.Secondly also fundamentally solved submarine cable and platform leg the wear and tear problem of submarine cable of fixation clamp fixedly the time.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of submarine cable water outlet fixing protector; Comprise that the formula of drowning oneself imitates anchor member, 90 ° of adpting flanges and non-corrosive metal (NCM) flexible pipe; The imitative anchor member of the said formula of drowning oneself plays protection, fixedly go to sea cable ditch place submarine cable and the effect that is connected the non-corrosive metal (NCM) flexible pipe; It comprises two halves formula taper connection head, two halves formula wedge shape inner cone, 90 ° of adpting flanges and half leaf formula connector; Said two halves formula taper connection head and two halves formula wedge shape inner cone protect steel wire outward and are connected with half leaf formula connector through prefastening force bolt and the 90 ° of adpting flanges cable ditch place submarine cable that will go to sea; Play submarine cable and when receiving external force, transmit the effect of external force to platform leg through the non-corrosive metal (NCM) flexible pipe; Said 90 ° of adpting flanges can connect the effect of imitative anchor member of the fastening formula of drowning oneself and non-corrosive metal (NCM) flexible pipe in 90 ° of scopes, said non-corrosive metal (NCM) flexible pipe plays to be protected behind the cable ditch that goes to sea and the effect of the exposed submarine cable between the platform leg fixation clamp.Because the imitative anchor component head of the formula of drowning oneself adopts conical design, so this member has under action of gravity from the sedimentation function, can play ballast, fixing and protect out the effect of trench place submarine cable.After being connected through the extra large cable pillar of imitative anchor member of the formula of will drowning oneself with the non-corrosive metal (NCM) flexible pipe of 90 ° of adpting flange heads and metal, behind the cable ditch of having realized going to sea and the hermetically sealed protection and the stressed transfer function of the exposed submarine cable between the platform leg fixation clamp.Through above means, finally solved behind the cable ditch that goes to sea in advance and the protection question of the exposed submarine cable between the platform leg fixation clamp.
The utility model has more following effects and good effect:
A kind of submarine cable fixing protector behind the cable ditch that goes to sea; Practical this device can be realized going to sea behind the cable ditch and the hermetically sealed protection and the stressed transfer function of the exposed submarine cable between the platform leg fixation clamp; Fundamentally solved the unsettled unguarded problem of this section submarine cable; Also solved former submarine cable fixedly goes out unstable problem of ditch submarine cable and submarine cable and platform leg fixation clamp wearing and tearing submarine cable fixedly the time in advance with the sandbag ballast after Hai Langou goes out ditch problem simultaneously; Is greatly improved the useful life of submarine cable, guaranteed the reliability and security of offshore oil exploration and development medium power electricity consumption.
