technical field

The utility model relates to the technical field of wind power generation, in particular to a regulating device for a near-ground low wind speed wind power generator.

Background technique

Wind power is a power machine that converts wind energy into mechanical work, also known as a windmill; broadly speaking, it is a thermal energy utilization engine that uses the sun as a heat source and the atmosphere as a working medium; wind power uses natural energy, which is relatively diesel. Power generation is much better; but if it is used in an emergency, it is still not as good as a diesel generator; wind power cannot be regarded as a backup power source, but it can be used for a long time. The speed of rotation is increased to cause the generator to generate electricity. According to the current windmill technology, the wind speed (the degree of breeze) of about three meters per second can start to generate electricity.

Most of the existing wind turbines with low wind speed near the ground do not have adjustment devices. When the wind is strong, the blades are subject to large wind resistance, which will not only cause the speed of the wind turbine to exceed its rated speed, but also cause the entire wind turbine to fail. damage.
