Three-blade propulsion and power generation two-purpose wind surf

Abstract

The invention discloses a three-blade propulsion and power generation two-purpose wind surf, which mainly comprises a generator set (1) and a wind surf rotating mechanism (9) fixed on a deck (10) of a hull, a wind surf mast (2) rotatably connected with the wind surf rotating mechanism (9) and only rotating toward the design direction, a first propulsion and power generation surf face (3) arrangedon the upper part of the wind surf mast (2) and connected with the wind surf mast (2) through a first propulsion and power generation surf face connecting rod (4), a second propulsion and power generation surf face (5) connected with the wind surf mast (2) through a second propulsion and power generation surf face connecting rod (11), a third propulsion and power generation surf face (8) connected with the wind surf mast (2) through a third propulsion and power generation surf face connecting rod (7), and a wind force and wind direction acquisition and analysis system (6) arranged on the top of the wind surf mast (2). The three-blade propulsion and power generation two-purpose wind surf can make the efficiency of the conventional surf improved by 20 to 40 percent, can operate under the condition of any wind direction in a main propulsion and auxiliary power generation mode, and saves the oil of a main engine or a generator of a ship by over 6 percent.

Description

technical field [0001] The invention relates to a marine sail, in particular to a three-bladed 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 to...
