A sealing and fastening device for non-armored underwater photoelectric composite cables

Abstract

The invention discloses a sealing and fastening device for non-armored underwater photoelectric composite cables, comprising a sealing and fastening main body, wherein, the sealing and fastening mainbody comprises an integral fastening part and a sealing part; the fastening part and the sealing part are provided with a fastening cavity and a sealing cavity which are communicated with each other;A lobe-type fastening cone sleeve is arranged inside that fasten cavity, the lobe-type fastening cone sleeve is respectively provided with an outer groove and an inner groove on the outer circumference and the inner circumference along the radial direction, a stainless steel ring is wound in the outer groove, a fastening nut is arranged at the end of the fastening cavity, and a pressing washer isarranged between the fastening nut and the lobe-type fastening cone sleeve; A plurality of sealing rings are arranged in the sealing cavity, a sealing flat gasket is arranged between adjacent sealingrings, a sealing nut is arranged at the end of the sealing cavity, and a sealing pressure gasket is arranged between the sealing nut and the sealing ring; Anti-loosening pressure plate is arrange between that sealing fasten body and the sealing nut; The sealing and fastening device disclosed by the invention has good waterproof and sealing effect, and ensures the sealing reliability of the photoelectric composite cable.

Description

technical field [0001] The invention relates to submarine cable sealing equipment, in particular to a non-armored underwater photoelectric composite cable sealing and fastening device. Background technique [0002] The underwater photoelectric composite cable separates the cables and optical fibers through the photoelectric separation cabin, supplies electric energy to the equipment in the submarine observation network, and establishes communication between the submarine observation equipment and the shore base station, which is an important part of the submarine observation network. . [0003] The penetration sealing performance of the photoelectric composite cable in the photoelectric separation cabin is the key to ensure the reliable operation of the submarine observation network. Under the action of external forces such as ocean current impact and fishing net dragging, the underwater photoelectric composite cable will be bent, stretched, etc., which will seriously affec...

AI Technical Summary

Problems solved by technology

Under the action of external forces such as ocean current impact and fishing net dragging, the underwater photoelectric composite cable will be bent, stretched, etc., which will seriously affect the effect of the photoelectric composite cable's penetration seal, causing serious safety hazards in the operation of the submarine observation network. Hidden danger

[0004] The land cable fastening device can fix the cable well, but it cannot meet the underwater sealing requirements and cannot be used directly
