Device special for laying underwater cable

Abstract

The invention discloses a device special for laying an underwater cable, comprising a dragging part and an anchoring part and is characterized in that the dragging part comprises an upper shell, a lower shell and a dragging head; the anchoring part comprises a base and an anchoring assembly for fixing the underwater cable; the upper shell and the lower shell are respectively fixedly connected with the anchoring assembly in a sealing way; the anchoring assembly is arranged in the lower shell; an inner cavity for filling waterproof sealant is arranged between the lower shell and the anchoring assembly; the base is sleeved on the lower shell; and the dragging head is fixedly connected to the upper shell in a sealing way and is in threaded connection with a hoisting screw. The device special for laying the underwater cable has the advantages that the underwater cable can be draught by only dismounting the base at the dragging stage of the underwater cable, the underwater cable can be fixed and installed through sleeving the base on the lower shell and then fixedly installing the base on a top flange of a J-shaped pipe or I-shaped pipe in an installing site when the underwater cable is needed to be installed and fixed after the dragging, thus, the construction operation efficiency of the underwater cable is increased, and meanwhile, the construction difficulty and strength are also reduced.

Description

technical field [0001] The invention relates to a cable laying device, in particular to a special device for underwater cable laying. Background technique [0002] The laying process of underwater cables includes traction and anchoring. At present, the traction of underwater cables mostly adopts the method of knotting and tightening rough metal mesh sleeves, which is similar to the traction of land cables. This traction device is prone to accidents during the traction process. Loose knots slip off, causing the entire underwater cable to sink into the bottom of the water, which brings great difficulties to laying and salvage, and this kind of traction device cannot seal the end of the underwater cable, but needs to seal the end of the underwater cable Additional sealing to prevent water ingress added additional work intensity to the laying construction. After the underwater cable traction is completed, an anchoring system needs to be installed at one end of the underwater ca...

AI Technical Summary

Problems solved by technology

However, at present, the traction and anchoring of underwater cables are two independent systems, which need to be installed and used separately during construction, which increases the difficulty of construction and the strength of laying, and also reduces the operating efficiency.
