Abstract
The invention relates to a lift-drag type vertical axis wind driven generator based on an overrunning combined mechanism, in particular to a lift-drag type vertical axis wind driven generator aiming at the problems of low generating efficiency, poor stability and low reliability of a lift-drag combined type vertical axis wind driven generator. A drag force wind rotor is arranged on a second drag force wind rotor shaft; a first lift force wind rotor shaft and a second lift force wind rotor shaft are arranged in a first drag force wind rotor shaft and the second drag force wind rotor shaft; thesecond lift force wind rotor shaft is connected with the first lift force wind rotor shaft through a first coupling; the first lift force wind rotor shaft and the first drag force wind rotor shaft are provided with a lift force wind rotor and the drag force wind rotor; the overrunning combined mechanism is fixed between the first lift force wind rotor shaft and the first drag force wind rotor shaft; the second lift force wind rotor shaft is connected with a lift force wind rotor generator through a second coupling, a third coupling and a third lift force wind rotor shaft; a drag force wind rotor speed increaser is arranged on a third drag force wind rotor shaft; the drag force wind rotor speed increaser is connected with a drag force wind rotor generator through a forth coupling; and the lift force wind rotor generator and the drag force wind rotor generator are connected with an energy storing device through a rectifier controller. The lift-drag type vertical axis wind driven generator based on the overrunning combined mechanism is particularly suitable for power supply of a region with large variation ranges of wind speed and wind direction.
Description
technical field [0001] The invention relates to a lift-drag type vertical axis wind power generator, which belongs to the technical field of wind power generation devices. Background technique [0002] There are two types of existing wind generators, one is a horizontal axis wind generator and the other is a vertical axis wind generator. [0003] The wind rotor of the horizontal axis wind turbine rotates around the horizontal axis. The generator needs to be installed at a high position, so installation and maintenance are very difficult. At the same time, the blades of the horizontal axis wind turbine need to be cantilever mounted, which is extremely easy to damage , short service life. In addition, horizontal-axis wind turbines cannot use tensioning devices, so they have poor wind resistance, and horizontal-axis wind turbines also need a windward control device, so there are problems of complex structure, many failures, and high cost. [0004] Vertical axis wind turbines ...
