Underwater adaptive mooring cable tension device

Abstract

The invention discloses an underwater adaptive mooring cable tension device which is mounted on a cable arranging device of an underwater winch of a main floating body of a submerged buoy and comprises a rotary seat, a cable access opening, a base and tension roller trains. The rotary seat is mounted on the base, is connected with the base by a thrust bearing and a radial bearing and can rotate by 360-degree angles on the horizontal plane. The cable access opening is connected onto the rotary seat by hinge support arms, and the hinge support arms can rotate around hinge shafts. The tension roller trains are arranged in the rotary seat and the base, and a mooring cable which is fed into the underwater adaptive mooring cable tension device from the cable access opening and penetrates the rotary seat and the base can be clamped by the tension roller trains. The underwater adaptive mooring cable tension device has the advantages that the rotary seat can rotate, the hinge support arms can rotate around the shafts, accordingly, the direction of tension for pulling a floater in the cable access opening can keep in the longitudinal direction of the mooring cable, loosening, tightening and shaking of the mooring cable due to fluctuation of waves and transverse acting force which is applied to the mooring cable under the effect of sea current can be effectively eliminated, and the environmental adaptability and the severe sea condition resistance of the underwater winch can be improved.

Description

technical field [0001] The invention relates to an underwater mooring cable device, in particular to an underwater mooring cable tensioning device. Background technique [0002] The profile environmental data of the upper ocean waters can help people reveal the law of air-sea interaction and influence, which is the most concerned by people and is very important for maritime navigation and military activities. The upper ocean waters are inaccessible to conventional submersible buoys, and the buoys moored in the upper waters are vulnerable to man-made damage. Therefore, it is particularly difficult to obtain real-time profile environmental data in the upper ocean waters. [0003] In order to make up for the defect that conventional submersible buoys cannot observe the upper ocean waters above the main buoy, the researchers designed a full-section marine monitoring submersible buoy system based on underwater winch technology. The system is equipped with an underwater winch to ...

AI Technical Summary

Problems solved by technology

[0005] The float of the underwater winch of the ocean full-section monitoring submersible buoy system goes back and forth between the main buoy and the sea surface. Under the influence of ocean dynamic factors, the traction mooring cable is constantly shaking, pulling, sometimes loosening and sometimes tightening, resulting in the mooring on the cable drum. The cable is loose, misaligned, knotted, or even detached from the cable drum, causing hidden dangers to the normal operation of the underwater winch

It will also happen that after the winch works for a period of time, the mooring cable is stuck on the cable winding drum and cannot be retracted. The lateral force caused by the ocean current will damage the underwater winch cable arrangement due to lateral pulling, which will affect the working life of the system.
