Problems solved by technology

[0004] However, the sails used by the above ships are usually fixed on the masts of a certain height, and there are height restrictions when passing through the channel and bridges, thereby limiting the area of ​​the sails, so that the energy-saving effect of the sails cannot be further improved
Moreover, under severe weather conditions, the wind speed is too high, and the exposed wing sails have certain safety hazards

Embodiment Construction

[0037] Please also refer to Figure 1 to Figure 7 , which is a wing sail 100 provided in 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, three telescopic masts 2 , 3 , 4 and a hydraulic cylinder 14 are accommodated 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, and they are arranged in sequence along the direction away from the base 10 , with gradually decreasing widths. In this embodiment, the central axes of the hydraulic cylinder 1...

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 connectedwith 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 sailing aids, in particular to a wing sail and a ship with the wing sail. Background technique [0002] Since the advent of the world's first ship powered by a steam engine, the mechanical propulsion system that directly drives the propeller with heat engines (such as diesel engines, steam turbines, and gas turbines, etc.) leading position. However, on the one hand, the internal combustion engine mechanical propulsion system of ships still has difficult problems such as high noise, small speed regulation 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. The time period of about 60 years has not yet been exhausted to find new sources of energy and their power plants. This is one of the great problems and challenges faced by mankind in the 21st century. Therefore, people have been working hard t...
