Problems solved by technology

The existing fairlead device is fixedly installed below the waterline. When the platform (ship) in the polar region is navigating, the seawater surface freezes, causing the fairlead device to contact and squeeze the ice layer, which increases the navigation resistance and easily damages the fairlead device.

Abstract

The invention relates to the technical field of marine winches and particularly discloses an underwater fairlead device. The underwater fairlead device comprises a pulley, a pulley shaft, a pulley support, a locking mechanism, a swing base, fixing shafts, an upper fixing base and a lower fixing base, wherein the upper fixing base and the lower fixing base are vertically fixed to the side faces of a hull, the swing base is fixed to the upper fixing base and the lower fixing base, the number of the fixing shafts is two, one end of each of the two fixing shaft is fixed to the swing base, the other end of each of the two fixing shaft is fixed to the upper fixing base and the lower fixing base respectively, the pulley support is connected with the swing base through a rotating pin shaft, the pulley is assembled on the pulley support through a pulley shaft, and the locking mechanism is used for locking the overturned pulley support on the swing base. The underwater fairlead device changes a single fairlead device mode into a movable mode, the position of the underwater fairlead device is changed, the problem that the fairlead device is in extruding contact with an ice layer due to seawater surface icing during navigation of an ice class ship and accordingly navigation resistance is increased, and the service life of the underwater fairlead device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of marine winches for ships and oceans, and in particular relates to an underwater guide cable device, which is used to change the navigation damping mechanism of an ice-class ship. Background technique [0002] An ice-class ship is a ship that can sail in a certain degree of ice conditions according to the classification rules and working conditions of the classification society. The cable guide device is a device to lead the cable from the inboard to the outboard to the wharf or other mooring locations, change the direction of the cable, limit its leading position and reduce the wear and tear of the cable. The underwater cable guide device in the prior art is composed of a roller bracket, a roller, a roller shaft, a swing seat, a fixed shaft, a rotating pin shaft, and an upper and lower fixed seat, etc., and is fixedly installed under the outer side of the platform (ship) shell, and is usually located at ...
