Sail and wind-energy comprehensive energy-saving ship

The utility model provides a sail and wind-energy comprehensive energy-saving ship. The sail and wind-energy comprehensive energy-saving ship comprises a main ship body, a main deck connected with the main ship body, a mast fixedly connected to the main deck, and a sail connected with the mast; an air turbine generator is arranged on the main deck; the sail is connected and forms a shape of a Chinese character 'AO' by a framework; an air outlet is formed at the bottom part of the 'AO'-shaped part, and is connected with one end of an air guide pipe; and a nozzle matched with the air turbine generator is connected to the other end of the air guide pipe. According to the sail and wind-energy comprehensive energy-saving ship, the air received by the sail can be used for providing wind energy to the air turbine generator by the air guide pipe when the sail is adopted for sailing, so that the air turbine generator can run to generate power; the whole sail and wind-energy comprehensive energy-saving ship is simple in structure and low in cost; the electricity is provided for the ship by the wind energy; and the wind-power generation and the sail aid-to-navigation are organically combined, so that the wind energy resource can be effectively utilized in a plurality of perspectives and a plurality of ways.
