Technical Field
The invention relates to the technical field of navigation aid of ship sails, in particular to a passive sail rotation control device.
Background
The ship sail navigation aid is a technology for improving the power of a ship and saving fuel by utilizing wind power, and has the advantages of reducing the oil consumption and emission of the ship, improving the navigational speed and stability of the ship and reducing the operation cost and maintenance cost of the ship. The principle of sailing a ship is to install one or more rotatable sails on the deck of the ship, and automatically adjust the angle and position of the sails according to wind direction and wind speed, thereby providing additional thrust to the ship. When the wind direction is at a certain angle (or called attack angle), the soft sail or the hard sail generates lift force and resistance force on the sail surface, and the sum of the component force of the lift force and the component force of the resistance force in the ship sailing direction is the thrust for propelling the ship. As shown in fig. 1, the conventional sail 100 includes a mast 110 and a canvas 120, wherein the lower end of the mast 110 is rotatably mounted on the hull 1, and the canvas 120 is fixedly disposed at the upper end of the mast 110.
If the mast can rotate freely, the sail automatically deflects to the downwind position like a flag, i.e. the position with the smallest moment, but at this point the angle of attack is zero and the sail does not generate thrust. In order to generate thrust for the sail, an additional counter moment is applied to the mast or sail surface to form an angle of attack with the wind direction. The counter moment may be generated actively, for example by means of a servo motor, or passively, for example by means of an additional auxiliary sail. The existing sail navigation aid (such as a movable sail and a sail adjusting method disclosed in the application number 202111500132.7) adopts a servo motor to actively control the rotation of the sail, and energy such as electric energy or chemical energy is consumed to obtain the force for driving the rotation of the sail, so that the effect of saving energy and reducing emission is not beneficial to improvement.
