Multi-mast rotating-type stack-up wind sail for ships

Abstract

The invention discloses a multi-mast rotating-type stack-up wind sail for ships. The wind sail comprises a mast component, a plurality of wind sail components and multiple pairs of cables. The mast component comprises multiple masts, and the masts are different in length and are sequentially fixed together in a stacked mode according to the length. The wind sail components are connected with the corresponding masts in a matched mode respectively. The cables are in a circular ring shape. One ends of the pairs of the cables are arranged on the corresponding masts in a sleeved mode respectively, and the pairs of cables are fixedly connected with the corresponding wind sail components at the same time. According to the multi-mast rotating-type stack-up wind sail for the ships, the masts different in length are arranged, the wind sail components are arranged on the masts, due to the fact that the larger the distance is from the sea level, the richer the wind energy is, the wind velocity gradient change on the sea is considered, a wind sail device designed according to the wind velocity gradient can fully utilize the wind energy of a higher space where the wind power is large and stable, the turbulence level of the air flow is small and interference factors are fewer, and thus ship stability is facilitated.

Description

technical field [0001] The invention relates to sails for the field of ships, in particular to a multi-mast rotary laminated sail for ships. Background technique [0002] In the process of navigating a ship, knowledge in various fields is often involved, such as the principle of aerodynamics, that is, when the fluid velocity increases, its internal pressure will decrease; for this reason, the air has to go around and bend outwards The surface of the sail must be accelerated, so the pressure decreases, generating suction, pulling the sail to one side, and the suction force generated by the reduced pressure on the leeward side of the sail is quite large, which can be twice as strong as the force pushing the sail on the windward side, which is The reason why people invented and used sails, and precisely because of the appearance of sails, those ancient ships lacking modern power propulsion devices can effectively use this kind of sails made of canvas or other fabrics hanging on...

AI Technical Summary

Problems solved by technology

But there is a problem that the traditional ship sails are composed of a main mast and several sails. The main mast is located in the middle of the sail to support the sail. The windward angle of the sail is controlled by pulling the rope.

And because the sail is installed on a main mast, this installation method makes it impossible for the sail surface of the whole piece of sail to be set very large, and it is also inconvenient for the operation of the windward angle of the sail; Installed in the midship of a small riverboat

For this reason, due to the large volume of modern large ocean-going ships, the sails installed with traditional structures cannot give enough thrust, and it is impossible to complete the control and deflection of large sails by pulling the rope.
