Abstract
The utility model discloses a bending limiting device of a submarine cable. The bending limiting device is characterized in that the bending limiting device comprises a flange and at least ten connecting bodies which are successively and mutually connected in an interval sleeving manner, that the flange is used for being fixedly connected with an underwater device on the end portion of the submarine cable, that an installing portion is fixedly disposed on the flange, that a first connecting body is connected with the installing portion in an interval sleeving manner, and that central holes used for passing through the submarine cable are disposed on the flange and in the connecting bodies. The advantage of the bending limiting device is that the device is sleeved on the connecting end between the submarine cable and the underwater device so as to reduce the bending degree of the connecting end of the submarine cable, the bending degree being generated by underwater dynamic effects. Therefore, overbending or fatigue failure which is generated at the connecting end of the submarine cable can be prevented and accident generation is prevented.
Description
Technical field
The utility model relates to a kind of protective device of extra large cable, relates in particular to the bend limiting device of extra large cable.
Background technology
Along with the continuous increase of China to energy demand, extract the dynamics of hydrocarbon resources also in continuous reinforcement from the ocean.And in energy extraction and the process that transports, extra large cable has obtained using more and more widely.And in the use of extra large cable, its end all will be connected with rigid member (being subsea equipment), but because extra large cable uses in the dynamic duty environment under water, tend to occur the phenomenon of overbend (being that curvature is excessive and stress concentrated) in the junction of extra large cable and subsea equipment, and the possibility of this junction generation fatigue failure is higher, cause serious harm for the usability of extra large cable, cause the generation of accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bend limiting device that prevents the junction overbend of extra large cable or produce the extra large cable of fatigue failure.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the bend limiting device of extra large cable, comprise ring flange and at least ten joints connector of mutual gap socket successively, described ring flange is fixedly connected with the subsea equipment that is used for being connected extra large cable-end section, be fixedly installed installation portion on described ring flange, be positioned at connector and the gap socket of described installation portion of first segment, be provided be used to the center pit of wearing extra large cable in described ring flange and described connector.
Described installation portion one is connected on described ring flange, be wholely set the first positioning convex ring on described installation portion, the front opening of described connector and be provided with detent, the rear end of described connector has been wholely set the second positioning convex ring, the detent that is positioned at the connector of first segment be socketed on described the first positioning convex ring and with described the first positioning convex ring clearance fit, the detent on a rear joint connector be socketed on the second positioning convex ring of last joint connector and with its clearance fit.
Described ring flange and described connector are by half-open identical two parts are fixedly formed.
Compared with prior art, the utility model has the advantages that this device is enclosed within on the link of extra large cable and subsea equipment, the degree of crook that the link that can reduce extra large cable produces because of dynamic action under water, thereby overbend occurs or produces fatigue failure, the generation of Accident prevention in the junction of avoiding extra large cable.
