[0002] Wind power generation technology is a technology that converts wind energy into electrical energy. It is achieved through a wind turbine, which uses the wind to drive the blades to rotate, thereby causing the generator to generate electricity. Existing generators are divided into horizontal-axis wind turbines and vertical-axis wind turbines. In most cases, both types of generators have a single impeller structure and can only start under relatively high wind speeds. Summary of the Invention

[0003] The purpose of the present invention is to provide a double horizontal-axis wind power generation device that can start under relatively low wind speeds, while improving the utilization rate of wind energy, thereby increasing economic benefits.

[0004] To achieve the above purpose, the present invention provides a double horizontal-axis wind power generation device, including a fluid collector, an impeller, a generator, a wind vane, a rotating mechanism, and a tower.

[0005] Preferably, in the above technical solution, in the double horizontal-axis wind power generation device, the rectifying plate of the fluid collector blocks the harmful wind for the normal operation of the impeller and rectifies it to the two air inlets on both sides, increasing the wind speed at the air inlets, enabling the generator to start and operate under relatively low wind speeds.

[0006] Preferably, in the above technical solution, in the double horizontal-axis wind power generation device, a double impeller structure is installed, and under the action of the fluid collector, the wind energy can be fully utilized to improve the utilization rate of wind energy.
