A platform anchoring device for a steel wire armored submarine cable

Abstract

The invention discloses a platform anchoring device for steel wire armoring of a submarine cable. The platform anchoring device is arranged right above a submarine cable protection tube and is characterized by comprising a pedestal and a submarine cable fixing device, wherein the pedestal is arranged right above the submarine cable protection tube, and a cable passing hole which allows the submarine cable to penetrate through is formed in the pedestal; the submarine cable fixing device comprises a lower bolster connected to the pedestal by bolts and an upper pressing plate connected to the lower bolster by bolts, wherein each of the lower bolster and the upper pressing plate is respectively provided with a hole which allows the submarine cable to penetrate through vertically, and an anchored steel wire of the submarine cable, which is obtained at an annular opening dissected in the submarine cable, is bent outwards and is then positioned between the lower bolster and the upper pressing plate. According to the platform anchoring device, the pedestal device which is provided with at least one cable passing hole is designed, the method of fixing the anchored steel wire of the submarine cable by the upper pressing plate and the lower bolster is adopted, and thus the problem of anchoring of at least one submarine cable at present is solved. Moreover, the platform anchoring device is simple and convenient in structure, convenient to operate and long and reliable in service life and has extremely high capability of resisting impact from stormy waves.

Description

technical field [0001] The invention relates to a platform anchoring device for steel wire armored submarine cables, in particular to a platform anchoring device for steel wire armored submarine cables with reliable anchorage and compact structure. Background technique [0002] With the development of the marine economy, submarine cables, submarine optical cables and submarine photoelectric composite cables and other submarine cable products are widely used in offshore oil platforms, offshore wind power, etc., and play a huge role in information or energy transmission. In order to prevent the submarine cable from falling due to its own weight and affecting its performance, various submarine cables must be fixed before entering the oil platform or power generation fan through the protective tube.

Problems solved by technology

[0003] Chinese patent CN200710156466.0 discloses a submarine cable fixing device. Using the cooperation of the annular clamping surface, the inverted tapered sleeve and the pressure plate, the inner surface of the inverted tapered sleeve and the inverted tapered hole will become Tighter, so as to avoid the risk of the submarine cable falling from high altitude due to its own weight, but using this structure is relatively complicated
