A conveniently adjustable submarine cable underwater joint hoisting construction device

Abstract

The invention discloses a submarine cable underwater joint hoisting construction device convenient to adjust, and belongs to the technical field of submarine cable hoisting. The device comprises two brackets which are parallel to each other; the two brackets are connected through a transverse plate; a rotating shaft is arranged between the two brackets; the two ends of the rotating shaft are respectively connected with corresponding brackets through bearings; first wire wheels are fixedly mounted on the two sides of the rotating shaft; a second wire wheel is mounted in the middle of the rotating shaft through a bearing; the second wire wheel is connected with the rotating shaft through a connecting mechanism; the connecting mechanism can enable the second wire wheel and the rotating shaftto rotate synchronously; an annular groove is formed in the periphery of the rim of one side of the second wire wheel; a motor is fixedly installed on the top face of the transverse plate, and a beltwheel is fixedly installed at the output end of the motor and connected with the annular groove through a transmission belt. The device can solve the problems of underwater crossing, looping and hardbending of a cable, two-point stress of the cable, large load of the cable, easy secondary damage and the like caused by underwater joint construction; and the device can be hoisted out of water without underwater unmooring of a diver, and can be repeatedly used.

Description

Technical field[0001]The invention belongs to the field of submarine cable hoisting, in particular to a submarine cable underwater joint hoisting construction device that is easy to adjust.Background technique[0002]Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunications transmission. Modern submarine cables use optical fibers as materials to transmit telephone and Internet signals. Each connection requires a connector box to connect. During the laying process of the joint box and the submarine optical cable, it is easy to bend due to the external force of the sea water and the laying equipment. This bending will seriously affect the communication performance of the optical cable. At present, the protective structure involved in this point, Either it cannot be recovered, or it needs to be equipped with underwater operators for recovery. The underwater recovery operations are difficult, strong, and dangerous for the operators.Summary...

AI Technical Summary

Problems solved by technology

During the deployment process of the connection between the splice box and the submarine optical cable, it is easy to bend due to the external force of the sea water and the deployment equipment. This bending will seriously affect the communication performance of the optical cable. At present, for the protection structure involved in this point, Either it cannot be recycled, or underwater operators need to be equipped for recycling, and underwater recycling operations are difficult, high-intensity, and dangerous to operators
