Embodiment Construction

[0037] Please refer to Figure 1 to Figure 7 , Which is a wing sail 100 provided by the first embodiment of the present invention. The wing sail 100 includes a mast body 1, a first telescopic mast 2, a second telescopic mast 3, a third telescopic mast 4, a sail surface 8, and a hydraulic mechanism.

[0038] The hydraulic mechanism includes a base 10, three positioning devices 13, and a hydraulic cylinder 14. The base 10 is fixed on the deck 11. The mast body 1 is arranged on the base 10 and can rotate relative to the base 10. In this embodiment, the three telescopic masts 2, 3, 4 and the hydraulic cylinder 14 are housed in the mast body 1. In this embodiment, the mast body 1, the first telescopic mast 2, the second telescopic mast 3, and the third telescopic mast 4 are all hollow, which are arranged in order along the direction away from the base 10, and the width gradually decreases. In this embodiment, the central axes of the hydraulic cylinder 14, the mast body 1, and the ...

Abstract

The invention provides a wing sail which comprises a mast main body, a sail face and at least one telescopic mast. The telescopic mast can move up and down along the mast main body. The sail face is supported by an upper framework and a lower framework, the upper framework of the sail face is fixedly connected with the telescopic mast, and the lower framework of the sail face is fixedly connected with the mast main body. The invention also provides a ship with the wing sail, which comprises an engine and an engine speed regulating device. The ship also comprises a detection device for detecting signals of wind velocity and wind direction, a revolution speed transducer for acquiring the actual revolution speed signals of the engine and a central control system. The central control system is used for calculating the sail angle of the wing sail and the revolution speed of the engine according to the wind velocity and wind direction information acquired by the detection device, controlling the rotation of the mast main body of the wing sail to adjust the sail angle of the wing sail and controlling the speed adjustment device to adjust the revolution speed of the engine. The wing sail and the ship with same have the advantages of energy saving and high safety.

Description

Technical field [0001] The invention relates to the field of sail assistance, in particular to a wing sail and a ship with the wing sail. Background technique [0002] Since the world’s first steam engine-powered ship came out, mechanical propulsion systems that directly drive propellers powered by heat engines (such as diesel engines, steam turbines, gas turbines, etc.) have become the main method of ship propulsion, occupying the power plant of ships. leading position. However, on the one hand, marine internal combustion engine mechanical propulsion systems still have difficult problems such as high noise, small speed range and poor flexibility; on the other hand, with the exhaustion of global oil resources, internal combustion engines will gradually withdraw from the stage of history. People must New energy sources and power plants have been found in about 60 years that have not been exhausted. This is one of the huge problems and challenges facing mankind in the 21st centur...
