Embodiment Construction

[0041] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0042] Such as Figure 1-Figure 6 As shown, the movable sail of this embodiment includes a sail base 1, and a turning mechanism is arranged on the sail base 1, and an auxiliary supporting sail surface 6 is connected to the turning mechanism; the top of the auxiliary supporting sail surface 6 is rotatably connected with a main sail surface 10,

[0043] The slewing mechanism rotates in the horizontal plane. The slewing mechanism includes a slewing motor 3. The output shaft of the slewing motor 3 is coaxially connected with a slewing gear 5. On the tooth surface of the slewing gear 5, an internal tooth slewing support bearing 4 is engaged to assist the sail. Surface 6 is fixedly installed on the top of the internal gear slewing bearing,

[0044] The included angle between the auxiliary support sail surface 6 and the main sail surface 10 is ...

Abstract

The invention relates to a movable sail and a sail adjusting method. The movable sail comprises a sail base and a slewing mechanism, and an auxiliary supporting sail surface is connected to the slewing mechanism; the top of the auxiliary supporting sail surface is rotationally connected with a main sail surface, the slewing mechanism rotates in the horizontal plane and comprises a slewing motor, an output shaft of the slewing motor is coaxially connected with a slewing gear, the tooth surface of the slewing gear is meshed with an inner tooth type slewing supporting bearing, the auxiliary supporting sail surface is fixedly mounted at the top of the inner tooth type slewing supporting bearing, and an included angle between the auxiliary supporting sail surface and the main sail surface is adjusted in a vertical plane; the auxiliary supporting sail surface and the main sail surface are rotationally connected through a rotating shaft; a rotating flange is fixedly mounted on the rotating shaft; and a swing electric cylinder is arranged on the auxiliary supporting sail surface, and the top end of an output shaft of the swing electric cylinder is hinged to the rotating flange. The windward angle of the sail surface can be changed according to the direction and magnitude of wind, and the effective wind direction range is wide through operation of the sail surface slewing mechanism.

Description

technical field [0001] The invention relates to the technical field of special marine equipment, in particular to a movable sail and a sail adjustment method. Background technique [0002] As a clean, safe and economical natural resource, wind resources, with the formulation and implementation of the global carbon peak and carbon neutral strategic goals, the use of sails to boost the function will become an important direction for the development of modern green ship technology. It is one of the hotspots of researchers' development and research. [0003] The design of sail booster should not only consider the boosting force and energy-saving effect it can produce, but also fully consider its own safety problems brought about by the extremely severe wind field environment from the perspective of safety. According to the theory of hydrodynamics, the aerodynamic lift generated by the sail surface is proportional to the square of the incoming wind speed. When the wind speed exc...
