The invention discloses a bendable-vertical-shaft wind power generator for a ship. The bendable-vertical-shaft wind power generator comprises fan blades, blade hoops, an upper blade support, a support supporting rod, a rotating shaft, a lower blade support, an upper tower frame, a lower tower frame, an upper-lower tower frame connecting hinge, a lower tower frame and inclined supporting rod connecting bolt, an upper tower frame and inclined supporting rod connecting bolt, a flange bearing, a tapered roller bearing, a base, rivets, a first coupler, a second coupler, a gear box, a power generator and an inclined supporting rod, the fan blades are welded on the rotating shaft through the blade supports, the rotating shaft sleeves outside the upper tower frame, the upper edge of the base is connected with the lower tower frame through the flange bearing while the lower edge of the same is connected with the lower tower frame through the tapered roller bearing, and the lower tower frame extends below a deck to be connected with the gear box which is connected with the power generator. The bendable-vertical-shaft wind power generator is free of wind facing problem, and wind in any direction can enable a fan to normally work; the tower frames are designed to be bendable, and the fan blades can be put down when the ship encounters extremely high wind, so that running safety of the wind power generator and the ship is guaranteed.
Description
technical field [0001] The invention relates to a vertical axis wind power generator, in particular to a bendable vertical axis wind power generator for ships. Background technique [0002] At present, most of the power consumption of ships is generated by diesel engines, which consumes a lot of fuel and costs high. Diesel engine power generation will also cause adverse effects on the marine atmospheric environment. In addition, the ship's dependence on fuel oil often has a non-negligible impact on the ship's endurance. Ships sailing at sea have abundant wind resources and good conditions for wind power generation. At present, on the eastern coast, some small wind turbines have been used on ships, but the power generation is not large, and some existing marine wind turbines are mainly based on the horizontal axis, because they have higher requirements for wind direction, while offshore wind direction Uncertain, so the utilization rate of wind energy is low. Large-scale wi...
