Practical marine cable winch

Abstract

The invention discloses a practical marine cable winch. The practical marine cable winch comprises a base, a main motor, a winding drum, a transmission shaft and a cable adaption device, wherein the two ends of the transmission shaft are fixed to a winch support seat. The practical marine cable winch is characterized in that the cable adaption device is composed of at least three adaptors, each adaptor is composed of a housing, a conductive rotary disc and a connection rotary shaft, each conductive rotary disc is located in the cylindrical cavity of the corresponding housing, and the space between each conductive rotary disc and the inner wall of the corresponding cylindrical cavity is filled with a saturated strong electrolyte solution; and each connection rotary shaft penetrates throughthe corresponding housing and is fixed to the centre of the corresponding conductive rotary disc, and an internal connection terminal is arranged on the end part of each connection drum. According tothe practical marine cable winch disclosed by the invention, in the rotation process of the transmission shaft, the housings and the internal connection terminals rotate with the transmission shaft, and the conductive rotary discs and the connection shafts are static, so that the power supply of an external power supply cable for a marine cable in winding and unwinding processes is realized, and the problems that a marine cable winch is liable to be corroded and nondurable due to a humid environment in the ocean during electric brush-slip ring power supply previously are solved; and the practical marine cable winch is remarkable in beneficial effects, and suitable for being applied and popularized.

Description

technical field [0001] The invention relates to a practical marine cable winch, in particular to a practical marine cable winch capable of realizing uninterrupted power supply of marine cables. Background technique [0002] During the use of ships, they often need to berth at the dock and use shore power. The marine cable winch is specially designed for receiving and unwinding shore power cables. At present, it is mostly used in full-turn tugboats, port tugboats, container ships, offshore oil multi-functional guard operation ships, naval landing ships, degaussing ships, anti-smuggling boats, patrol boats and other ships. Traditional cable winches come in two forms. One is a non-slip ring winch, and the other is an end face slip ring winch. The former can only be used to store cables, and the cables still need to be disassembled or connected when retracting and unwinding the cables; the latter uses end face slip rings, and if ordinary brushes are used, it is easy to cause ...

AI Technical Summary

Problems solved by technology

The former can only be used to store cables, and it still needs to be disassembled or connected when the cables are retracted; the latter uses end face slip rings, such as ordinary brushes, which may easily cause loose contact of the brushes, causing failures such as phase loss and heating. Can be used in occasions with low requirements and low current
