Lifting drum sail device and method of use

Abstract

The invention discloses a lifting type rotary drum sail device. The device comprises a supporting assembly, a shear fork type lifting assembly and a sail assembly. The sail assembly and the shear forktype lifting assembly are installed on the supporting assembly. The shear fork type lifting assembly is positioned in the sail assembly; the sail assembly comprises an outer cylinder, a first inner cylinder, a second inner cylinder, a baffling assembly and two guiding assemblies; and the shear fork type lifting assembly comprises a lifting plate, a bearing plate, an electric cylinder, two sets offirst supporting rods and two sets of second supporting rods, the two sets of guide assemblies comprise two sets of sliding blocks and two sets of sliding grooves, and the supporting assembly comprises a fixing plate, a supporting plate, a supporting shaft and a power assembly. The rotary drum sail device can solve problems that when an existing rotary drum sail device utilizes wind energy, a wind energy contact surface is limited, a wind energy utilization rate is low, the rotary drum sail device cannot be lifted, and operation of a suspension arm on cargo loading and unloading of a ship iseasily affected.

Description

technical field [0001] The invention relates to the technical field of cyclone sails, in particular to a lift-type cyclone sail device and a method for using the same. Background technique [0002] Since the 21st century, with the rapid growth of the global economy, global trade has also been accelerating. In international trade, about 90% of the goods are transported by sea, because sea transportation has significant advantages such as low cost and large volume. But it cannot be overlooked that CO 2 emissions from maritime transport are constantly affecting the global climate. In the 30 years since the shipping crisis in 1980, both total CO 2 emissions and total ship emissions have increased globally. Especially between 1979 and 2009, total ship emissions have doubled. In 2007, Total CO 2 emissions from ships account for 3% of total global emissions. In this context, the global standards for environmental protection of ships are constantly improving, and relevant laws an...
