Description

Floating diversion vertical axis wind turbine

The present case is a floating diversion vertical axis wind turbine, especially a blade with a rotating capability, and is applied to a floating diversion vertical axis wind turbine of a vertical axis wind turbine.

The conventional wind turbines are designed according to the structural design of the bearing shaft, and can be divided into a horizontal axis wind turbine (HAWT) and a vertical axis wind turbine (VAWT). The main axis of the horizontal axis wind turbine is parallel to the wind direction, while the main axis of the vertical axis wind turbine is perpendicular to the wind direction.

The advantage of the conventional horizontal-axis wind turbines is that the power generation efficiency is high, so most commercial applications and large-scale wind turbines such as the coastal areas of Taiwan use horizontal-axis wind turbines. However, since the fan structure of the horizontal axis wind turbine must be operated toward the wind direction source, it is necessary to rely on the installation of the guide vane to follow the wind direction source. Also, the blade needs to be constantly adjusted with the wind direction, resulting in the horizontal axis wind turbine. More susceptible to terrain and features.

In contrast, conventional vertical-axis wind turbines do not need to adjust direction as the wind direction changes, and all wind directions can operate, so the conditions for installing the environment are more limited. less. Conventional vertical-axis wind turbines mainly use the S-shaped blade barrel rotor (Savonius), and the force generated by the wind on the downwind blade is greater than the force generated on the upwind blade, which causes the blade to rotate. However, since the upwind blade generates resistance to the rotation of the downwind blade, the rotational speed is relatively slow and the power generation efficiency is low.

The conventional technology has the following disadvantages: 1. Conventional horizontal-axis wind turbines, the blades need to be constantly adjusted with the wind direction, so they are more susceptible to terrain and features; 2. Conventional vertical-axis wind turbines due to upwind blades It will generate resistance to the rotation of the downwind blade, so the rotation speed is relatively slow and the power generation efficiency is low.
