Darrieus propulsion power generating dual-purpose type sail

Abstract

The invention discloses a Darrieus propulsion power generating dual-purpose type sail which mainly comprises a generator set (1), a sail rotating mechanism (28), a sail mast (2), a propulsion sail surface, a vertical shaft Darrieus wind power generating blade (19) and a wind force and direction collecting and analyzing system (14), wherein the generator set (1) and the sail rotating mechanism (28) are fixed on a ship deck (29); the sail mast (2) is rotatably connected with the sail rotating mechanism (28) and rotates only towards the design direction; and the propulsion sail surface connected with the sail mast is arranged at the upper part of the sail mast, the vertical shaft Darrieus wind power generating blade (19) is connected with the propulsion sail surface, and the wind force and direction collecting and analyzing system (14) is installed at the top of the sail mast. The invention can improve the efficiency of the conventional sail by 20 percent to 50 percent; and by adopting two energy-saving ways, the Darrieus propulsion power generating dual-purpose type sail can be run under any wind direction condition and save ship host machine or engine oil by more than 6 percent and has greater economy, practicability and social value.

Description

technical field [0001] The invention relates to a marine sail, in particular to a Darrieus-type propulsion and power generation dual-purpose sail. Background technique [0002] Wind energy is a renewable energy with large-scale development potential. The oil crisis in the 1970s made people realize the importance of wind energy utilization on ships. The research on modern sailing ships has become the research focus of some developed countries, such as Germany, Japan, Sweden and Denmark. [0003] Foreign practice has proved that using sails as auxiliary power for ship navigation can reduce the fuel consumption of the ship's main engine by 10% to 30%, and it is difficult for ship engineers to increase the efficiency of engines and propellers by 1% to 2%. For ship transportation where fuel costs already account for 40%-60% of operating costs, sail booster technology is undoubtedly very attractive. Therefore, some people think: "sail assist technology is the best known method t...
