Description

technical field [0001] The invention relates to a fan steering device, in particular to a large-scale wind power generator steering device. Background technique [0002] Wind is a natural phenomenon that we can touch everywhere in our daily life. It is the most familiar to us. It is reported that the wind on the earth is the uneven heating of the earth's surface atmosphere caused by solar radiation, which causes uneven atmospheric pressure distribution. Under the action of pressure, the air moves in the horizontal direction to form wind, and the energy generated by the wind is wind energy. As a carrier of energy, compared with traditional fossil fuel energy, when it is converted into usable electrical energy , there is neither fuel cost nor wastes such as carbon dioxide, sulfur dioxide, nitrogen oxides, carbon monoxide, dust, etc. polluting the environment. It is a clean and renewable energy source. more and more attention from all over the world. my country is affected by...

Problems solved by technology

[0003] Whether modern wind turbines have three blades or four blades, their wind energy utilization rate is relatively low. Therefore, in order to develop wind power generation on a large scale, it is a crucial technology to solve the wind energy utilization rate of wind turbines. Although wind power generators have been used for a long time, due to the above reasons, people's development and utilization of wind energy is still in a "negligible" state. Most of the current wind power generators are in the form of fixed fans. Receiving wind energy, its utilization rate of wind energy is very low

Among the existing published patented technologies, in 2008, someone proposed a multi-wind direction speed-up wind power generation device. It mainly uses a reverse flow air duct with a wide outside and a narrow inside to increase the contact surface of wind energy. However, this method increases the contact surface at the same time. It also increases the weight of the fan, and when the fan rotates, it will also increase the energy to overcome its own weight, so that the purpose of improving the utilization rate of wind energy cannot be achieved very well.

In 2011, someone invented a wind deflector device for a wind power tower. The device operates by setting the wind direction data detected by the anemometer at the top of the power tower, and then drives the entire power tower to turn to increase the number of blades. The wind pressure and air flow rate can be increased to improve the utilization rate of wind energy, but the device only reduces the volume of the fan in the final analysis, but the wind direction data measured by the anemometer is only mechanically transmitted to the fan. In this link, wind energy The utilization rate still cannot reach the maximum

[0004] Therefore, the current packing device for wind power generators is not sensitive to wind direction tracking, and the utilization rate of wind energy is not ideal.
