AI Technical Summary

Technical Problem

The existing sails' blind-sighted area design of tankers does not meet the requirements of the convention, and in extreme weather, it is easy to lead to poor ship stability, and the sail is high in the center of the car and difficult to store.

Method used

A retractable airfoil sail is designed, including a sliding lifting plate, a foldable airfoil sail and a lifting drive mechanism. The sail can be folded and stored in the sail storage chamber inside the deck as needed. Through the distributed structural design of multiple retractable airfoil sails, it meets the convention requirements of blind-sighted areas.

Benefits of technology

The free collection and release of sails is achieved, which avoids the problem of blind-sighted areas not meeting the requirements of the Convention, and reduces the impact on ship stability in extreme weather. At the same time, the folding design of the sail avoids obstacles to loading and unloading goods.

Abstract

The retractable airfoil-shaped sail comprises a sliding type lifting plate, a folding airfoil-shaped sail body and a lifting driving mechanism, a sail storage cavity matched with the folding airfoil-shaped sail body is formed in a deck of the oil tanker, and the folding airfoil-shaped sail body is arranged in the sail storage cavity. The sliding type lifting plate is arranged in the sail containing cavity in a sliding mode and can ascend and descend in the sail containing cavity in the vertical direction, the sliding type lifting plate is connected with the lifting driving mechanism and driven by the lifting driving mechanism, and the folding type wing-shaped sail is fixed to the upper side of the sliding type lifting plate. By means of the design of the retractable wing-shaped sail, the sail is folded and stored in the sail storage cavity in the deck through the sliding type lifting plate, cargo loading and unloading can be prevented from being hindered, and the influence of extreme weather conditions on the ship can be reduced; and secondly, through the distributed structure design of the retractable wing-shaped sails, the blind view area design of the sails meets the convention requirement of the blind view area of the ship.
