Abstract

The invention discloses a low-speed wind turbine generator. In the generator, a bracket is arranged on the upper end of a base; a generator is arranged on the bottom end of the bracket; the upper end of the generator is provided with a transmission shaft; the lower end of the transmission shaft is arranged on a rotor shaft of the generator through connection of a connecting plate; the upper end of the transmission shaft is provided with a wind turbine shaft; the lower end of the wind turbine shaft is provided with a support shaft sleeve, while the upper end is provided with a wind turbine; and when the low-speed wind turbine generator is used, the base can be arranged on the roof of a one-storey / two-storey house, an arc impeller blade absorbs natural wind from different directions to generate wind power which is ten times higher than that of a traditional fan, and the wind power is transferred into a larger moment to drive the unit to generate electricity and apply work.

Description

technical field [0001] The invention relates to a wind power machine, specifically a low-speed wind power generator. Background technique [0002] my country is located in the subtropical region, and places with wind speeds of 2 to 3 for many years account for more than 70% of the country's area. The wind turbines currently used mostly adopt the traditional three-blade structure. The wind power of this structure Due to the scarcity of blades, the wind energy obtained from the wind speed is small, and the effective wind speed needs to be above level 4 to operate and generate electricity. It is impossible to promote and utilize this natural wind resource in weak wind areas. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a low-speed wind power generator composed of large-torque wind rotor blades, so as to solve the problem that the existing wind turbines cannot generate electricity normally at low...
