Deep-sea cable laying system of manned submersible

Abstract

A deep-sea cable laying system of a maned submersible comprises a manned submersible. A hydraulic source and a valve box are mounted in the tail of the submersible, a cable laying winch is mounted in an operation cabin of the submersible and comprises a box body, a reel motor driving a reel to rotate and a conveying motor driving a conveying wheel to rotate are mounted in the box body, a length and speed measuring approach switch is mounted on the reel, a shearing oil cylinder with a shear knife is assembled at one end of the box body, a winch valve box is mounted at the other end of the box body, a cutoff indication approach switch is mounted on the outer wall of the box body corresponding to the shearing oil cylinder, and cables are conveyed to the sea bottom by sequentially winding the reel and the conveying wheel. A wiring box is mounted in the operation cabin of the submersible arranged at the outer end of the box body, an observation window is mounted at the end of a manned cabin, a top camera is arranged mounted at the top of the manned cabin, and a monitor, a winch control box and a manual hydraulic pump are mounted in the manned cabin; a bottom camera is mounted at the bottom end of the outer side of the tail of the manned submersible. Safety of sea bottom information network is guaranteed.

Description

technical field [0001] The invention relates to the technical field of manned submersibles, in particular to a deep-sea cable laying operation system for a manned submersible. Background technique [0002] With the continuous expansion of global communication, seabed exploration and marine energy development, underwater submarine cables are used more and more widely, while traditional cable-laying ships are greatly affected by sea wind and waves, and their operating time is limited to a certain extent. With the increase of seawater depth, the cable laying ship needs to constantly adjust the speed or tension of the cable. The actual operation is difficult, and it is easy to cause the submarine cable to be suspended or piled up. Real-time observation is carried out, and the path of the cable-laying ship sailing on the water surface is easy to be detected and recorded, which exposes my country's submarine information network and poses a huge security risk. [0003] In order to ...

Problems solved by technology

[0002] With the continuous expansion of global communication, submarine exploration and marine energy development, the use of underwater submarine cables is becoming more and more extensive, while traditional cable-laying ships are greatly affected by sea wind and waves, and their operating time is limited to a certain extent.

With the increase of seawater depth, the cable laying ship needs to constantly adjust the speed or tension of the cable. The actual operation is difficult, and it is easy to cause the submarine cable to be suspended or piled up. Conduct real-time observation, and at the same time, the path of the cable-laying ship sailing on the water surface is easy to be detected and recorded, which exposes my country's submarine information network and poses a huge security risk
