Problems solved by technology

Especially since the sail unit is installed amidships, it will block the view of the bridge
In order not to hinder the navigation line of sight, the sail surface needs to be higher than the bridge, which will greatly increase the center of gravity and heeling moment of the ship, reduce the stability of the ship, and affect the safety of ship navigation

Embodiment Construction

[0027] The present invention will be further elaborated below by describing a preferred specific embodiment in detail with reference to the accompanying drawings.

[0028] like Figure 5 As shown, a multi-joint asymmetric marine sail system installed on both sides of a ship includes a plurality of asymmetric sails and a stay cable 7, and the multiple asymmetric sails are combined in series through the stay cable 7, Realize the linkage control of the windward angle of the sail surface.

[0029] like figure 1 As shown, the asymmetric type sail includes: a rotating mechanism, a sail frame, a sail 1 and a pair of support rods 2 connected with the cable 7; the rotating mechanism includes a rotating shaft 3, a base 4 arranged on the edge of the ship deck The described rotating shaft 3 is vertically arranged in the base 4, and the inside of the base 4 is provided with a turntable, which plays a protective role and drives the steering of the rotating shaft 3; the described sail fram...

Abstract

The invention discloses a multi-connection asymmetric type sail system for ships. The multi-connection asymmetric type sail system for ships comprises a plurality of asymmetric type sails and an inhaul cable, the multiple asymmetric type sails are combined in series through the inhaul cable, and linkage control over the windward angles of the sail surfaces is achieved. The multi-connection asymmetric type sail system for ships has the advantages that rotation of the sails is controlled in a linkage mode through the inhaul cable transmission mode, the windward angles of the sails can be adjusted conveniently at the same time, and a sail control device is simplified; by the adoption of the asymmetric sail surfaces, the sails can be installed at the two sides of one ship conveniently, and the sight of a console is prevented from being disturbed; as the whole sail surfaces can descend to be at the height of a main deck, stability of the ships is improved, and maintenance of the sails is also facilitated.

Description

technical field [0001] The invention relates to the field of sailing aids, in particular to a multi-connected asymmetric marine sail system. Background technique [0002] The tight energy supply and rising oil prices have brought great pressure to shipping companies. Marine wind energy resources are abundant, and sailing aids navigation is to use wind power as auxiliary power for ship propulsion. At present, most of the sail navigation aids are installed at the midship position on the main deck of the ship, and in order to facilitate the manipulation of the sail surface, they are all symmetrically designed to reduce the turning moment of the sail. Each sail is controlled separately to realize the rotation and retraction of the sail, which requires multiple sets of control systems. Especially since the sail unit is installed in the midship position, it will obstruct the view of the bridge. In order not to obstruct the sight of navigation, the sail surface needs to be highe...
