Description

Rotating arm and wind power generation equipment

Technical Field

The utility model relates to a wind power generation technical field, in particular to swinging boom and wind power generation equipment.

Background

The existing generator uses natural energy to provide power and has a lot of instability. For example, wind power generation completely depends on the wind energy of nature, and cannot ensure the power completely and effectively supplied to the generator, and once the wind power is too low, the generator stops running and is very difficult to restart. The generated energy is greatly influenced by weather, the wind power control capability is very low, and the rated rotating speed of the generator is often exceeded or not reached, so that the generator is damaged or cannot generate electricity effectively.

The wind power generation principle is that wind power is used for driving windmill blades to rotate, and then the rotating speed is increased through a speed increaser so as to promote a generator to generate electricity. The wind power generation does not relate to the problem of fuel and does not produce radiation or air pollution, so the wind power generation is a clean and environment-friendly power generation mode.
