Abstract

The invention discloses a wind power generator comprising a tower, a first wind wheel, a cabin, a first wheel hub, a first main shaft, a first generator set and a yaw driving system, wherein the first wind wheel comprises a plurality of vanes, the cabin is installed on the tower, the first wheel hub is used for installing the first wind wheel, the first main shaft extends out of one end of the cabin, the first generator set is arranged in the cabin, and the yaw driving system is arranged at the lower end of the cabin; and one end of the first main shaft is connected with the first wheel hub, and the other end of the first main shaft is connected with the first generator set through a first drive system. The wind power generator also comprises a first wind wheel, a second wheel hub, a second main shaft and a second generator set, wherein the first wind wheel comprises a plurality of vanes, the second wheel hub is used for installing the second wind wheel, the second main shaft extends out of the other end of the cabin, and the second generator set is arranged in the cabin; and one end of the second main shaft is connected with the second wheel hub, and the other end of the second main shaft is connected with the second generator set through a second drive system. The wind power generator has low cost and can effectively improve the utilization rate of wind energy.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. A wind turbine is a power machine that converts wind energy into mechanical work and then into electrical energy. Its core technology is to maximize the utilization of wind energy as much as possible. Most of the existing wind turbines have a single wind rotor and three blades. The wind blade is the most important part of the wind turbine. It should not only run smoothly, but also have the maximum power performance. It should start at lower wind speeds. The wind turbine rotates and reache...
