Abstract

The rudder-free application is realized on the sailing boat through the combination of the sail and the electric adjustable-pitch propellers on the two sides of the stern, and the energy efficient utilization of converting part of water flow energy flowing through the propellers into electric energy is realized.

Description

Combination of sail and electric variable pitch propeller realizes no rudder and high-efficiency utilization of energy
Technical Field
The wind energy and water flow energy conversion device is applied to the fields of sailing and more effectively converting wind energy and water flow energy into electric energy which can be stored and used.
Background
When the sailing boat sails, the stress center on the sail and the resistance center of the boat in water need to be adjusted to be the same vertical line to enable the boat to sail along the direction of the positive bow, otherwise, a deflection force exists. Traditionally rudder deflection is an important factor in achieving this adjustment. The adjustable pitch propeller can change the resistance state of the propeller in water through the adjustment of the pitch, and if the adjustable pitch propellers are respectively arranged on the two sides of the stern, the function realized by the rudder in the traditional mode can be realized through the adjustment of the two propellers with different pitches. While the motor may also be a generator.
Disclosure of Invention
The two sides of the stern are respectively provided with the electric adjustable pitch propellers to realize the function of the rudder, and simultaneously, the water flow passing through the paddle area pushes the propellers to rotate to enable the motor to generate electricity and charge the battery on the ship, thereby utilizing the energy flowing away.

Claims (2)

1. The function of a rudder device on a traditional sailing boat is replaced by a mode of installing electric variable-pitch propellers on two sides of the sailing boat.
2. Meanwhile, the water flow passing through the propeller part at the stern can be driven by the propeller to rotate so as to drive the motor to generate electricity and convert the electricity into electric energy to be stored on the ship.
