Rotating scoop speed-regulating type vertical axis wind power generation device

Abstract

The invention relates to a rotating scoop speed-regulating type vertical axis wind power generation device comprising a generator; and a driving wind wheel mechanism and a speed regulating wind wheel mechanism which are contacted are respectively sheathed on a shaft of the generator from top to bottom. The driving wind wheel mechanism is used for converting wind energy into mechanical energy to drive the generator to generate electricity, and a wind scoop on a wind wheel is provided with a concave surface and a convex surface, the concave surface is used for adsorbing the wind energy and can generate resistance to push the wind wheel to rotate, the convex surface is a guiding surface and is used for reducing the friction resistance of the wind scoop and air flows in the running process ofthe wind scoop, so as to reduce the wind wheel energy loss, so that the rotating speed of the wind wheel can be changed only by changing different angles of the concave surface and the convex surfaceof the wind scoop to the wind direction. In the device, a complete mechanical structure is adopted, additional power is not needed, and complex and damageable electronic parts are not needed, therefore, the structure is safe, the performance is reliable and the use is convenient.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a rotating bucket speed regulating vertical axis wind power generating device. Background technique [0002] At present, with the decrease of mineral resources, the development and utilization of new energy is becoming more and more urgent for human beings. Wind power is the renewable new energy with the most developed scale. It has many advantages such as no pollution, renewable, no need for transportation, and easy installation. Much attention and use by people. However, the natural wind speed is unstable and ever-changing. In terms of wind power generation, when the wind speed exceeds the cut-out value, if the wind turbine does not have a reliable and flexible speed regulating device, it will have a destructive effect on the safety of the wind turbine. Therefore, the adjustment of the wind turbine The speed device is an important device to protect the performance and safety o...

However, the natural wind speed is unstable and ever-changing. In terms of wind power generation, when the wind speed exceeds the cut-out value, if the wind turbine does not have a reliable and flexible speed regulating device, it will have a destructive effect on the safety of the wind turbine. Therefore, the adjustment of the wind turbine The speed device is an important device to protect the performance and safety of the unit

Most of the current vertical-axis wind turbines do not have a speed regulating device. The wind speed is low and the wind speed is high, and the wind speed is high. It is difficult to survive by itself when encountering a strong typhoon.
