Problems solved by technology

The present invention does not integrate the air-permeable mast and the cylindrical sail, and cannot use the combination of the air-permeable mast and the cylindrical sail to provide auxiliary power for the ship
[0004] The cylindrical sail technology is suitable for sufficient installation space on the deck, high rate of sailing time for operation characteristics, and prevailing monsoons on the ocean during sailing. At present, there is no combination of cylindrical sails and ventilating masts. While ensuring the function of ventilating masts, cylinders are used Sails provide additional auxiliary power for ship navigation

Abstract

The invention discloses a ventilation mast sail device of an LNG ship. The ventilation mast sail device comprises a ventilation mast, a ventilation mast cover cylinder, a cylindrical sail, a bearing, a hub motor assembly, a motor sail connecting piece, a hub motor supporting piece, a cover cylinder supporting piece and a cover cylinder fixing piece. A ventilation mast cover cylinder is installed on the ventilation mast, the cylindrical sail is connected with the hub motor assembly through a motor sail connecting piece, the cylindrical sail is installed on the ventilation mast cover cylinder, and the invention further relates to an LNG transport ship used for the LNG ship ventilation mast sail. The LNG ship ventilation mast and the cylindrical sail are combined together, the space for arranging the cylindrical sail is saved, meanwhile, the cylindrical sail is used for providing auxiliary power for the LNG ship, sailing oil consumption is reduced, the effects of energy conservation and emission reduction are achieved, and the shipping cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a ventilating mast sail device and an LNG ship using the ventilating mast sail. Background technique [0002] The current international energy shortage situation is becoming more and more severe, and the development and utilization of renewable new energy has become an urgent requirement. Wind energy is an important clean energy with the characteristics of abundant resources, renewable and non-polluting. In recent years, wind energy has been applied in the marine transportation industry, and the use of wind-powered sails to assist ships in navigation has gradually become an ideal measure for energy-saving and emission reduction of ships. [0003] Patent No. CN112339909A discloses a cluster-type ventilation mast and a liquefied gas ship using the cluster-type ventilation mast. On the open-air area of ​​the ship, a heating coil is arranged inside the combination base, and a ...
