AI Technical Summary

Problems solved by technology

The advantage of the Savonius drum is that it has a large starting torque and can be self-started at almost any wind speed. However, since the Savonius drum cannot rotate beyond the wind speed, it cannot generate a large Magnus lift and the wind energy conversion rate is low.

Embodiment Construction

[0017] In order to make the marine wind-assisted navigation drum of the present invention easy to understand, it will be further elaborated below in conjunction with the accompanying drawings.

[0018] In the present invention, an air flow unit is arranged on the outer peripheral surface of the rotating cylinder 1 to increase the Magnus lift generated on the rotating cylinder 1 so as to achieve the purpose of reducing energy consumption.

[0019] The wind-assisted navigation drum of the present invention includes a rotating cylinder 1, a rotating cylinder driving motor 4, an air flow unit, an end plate 2, and a cylinder rotating shaft 5, and the end plate 2 is installed on the top of the rotating cylinder 1 , and is fixedly connected with the rotating cylinder 1 coaxially and with the center of the circle. The air flow unit is installed on the outer surface of the rotating cylinder 1. By generating air flow on the outer peripheral surface of the rotating cylinder 1, the Magnus ...

Abstract

The invention provides a wind-assisted rotary cylinder with a spiral side plate. The wind-assisted rotary cylinder with the spiral side plate comprises a rotary cylinder, a rotary cylinder drive motor, a cylinder rotating shaft, an end plate and an air flowing unit. The rotary cylinder drive motor is installed on the bottom of the cylinder and connected with the rotary cylinder through the cylinder rotating shaft. The end plate is arranged on the top of the rotary cylinder and coaxially, concentrically and fixedly connected with the rotary cylinder. The air flowing unit is arranged on the outer surface of the rotary cylinder, and when the rotary cylinder rotates, the air flowing unit enables the Magnus lift force to be increased. The marine wind-assisted rotary cylinder can achieve efficient auxiliary propulsion from a low-wind-speed region to a high-wind-speed region.

Description

technical field [0001] The invention relates to a ship's wind-powered navigating drum, in particular to the outer peripheral surface of the rotating drum of a propulsion device provided with helical protrusions. Background technique [0002] In recent years, due to the global energy shortage and the sluggish shipping situation, ship energy-saving technology has become one of the hot spots in the research of the shipping industry. At the same time, as countries around the world pay more and more attention to environmental protection, the shipping industry and shipbuilding industry have formulated various specifications to meet the increasingly stringent energy-saving and environmental protection requirements. Energy issues and new emissions regulations present challenges to the global newbuilding market, but at the same time present a new opportunity for growth. A series of green ship technology products have been designed and developed, and it is an important way for the sh...
