Sea cable anchoring device

Abstract

The invention discloses a submarine cable anchoring device which comprises a seat, inverted tapered holes arranged on the seat, inverted tapered coverings arranged in the inverted tapered holes with the outer surface of the inverted tapered covering matched with the inner surface of the inverted tapered hole and a pressing plate arranged above the seat which is connected with the seat through connectors. The pressing plate is provided with a ring-shaped clamping surface which is matched with the contour of the upper part of the inverted tapered covering. Mounting holes are arranged along the edges of the seat and connected with external. The invention has the advantages that, as the ring-shaped clamping surface of the pressing plate is matched with the contour of the upper part of the inverted tapered covering and the inverted tapered covering is matched with the inverted tapered hole on the seat, the inverted tapered covering closely fits with the inner surface of the inverted tapered holes under the pressure of the pressing plate, and tightly clamps with the inner surface of the inverted tapered hole owing to the self weight of the submarine cable, thereby ensuring the submarine cable to be effectively fixed to a working platform. The invention has the advantages of strong mechanical strength, strong resistance to seawater corrosion, simple structure and reliable performance. The invention is suitable to be used for deep well service or other working platforms.

Description

technical field [0001] The invention relates to a cable fixing device, in particular to a submarine cable anchoring device. Background technique [0002] With the rapid development of economy and construction, many offshore islands and marine facilities such as offshore oil and natural gas work platforms have demands for various resources such as electricity, communications, fresh water, oil, and gas, and various seabeds have to be deployed separately. A large number of pipelines such as optical cables and submarine power cables. Especially in the offshore oil production site of the oil industry, the power transmission of each oil production platform is completed by various submarine cables, and the submarine cable often causes the submarine cable to fall due to its own weight and affects the normal production of oil. To solve this problem, oil production workers usually use a The fixing device fixes one end of the sea cable to the oil production platform or other fixed obj...

AI Technical Summary

Problems solved by technology

However, due to the heavy weight of the submarine cable, various fixing devices are not enough to effectively anchor the submarine cable, and the submarine cable still cannot be completely fixed and falls, which affects the oil production work.
