Spiral turbine blade and vortex convective wind power generator

Abstract

The invention relates to a spiral turbine blade sheathed on a rotor; the blade comprises a cylindrical wind wheel body and at least two blades installed on the wind wheel body; the blades are spirally distributed on the wind wheel body at equal intervals; and the blades are bulges formed on the wind wheel body and are gradually thinned from the root to the outside. The vortex convective wind power generator comprises a vertical column and a cylindrical air guide cylinder installed on the vertical column and arranged horizontally; the spiral turbine blade and the wind power generator are installed in the air guide cylinder; both ends of the air guide cylinder are respectively provided with a trumpet-shaped air collecting opening; and the air collecting opening is internally provided with a flow guide device. The blade is more stable in structure, firm and durable, and good in air collecting effect, but has no rotation resistance; a spiral structure is adopted, and the wind energy can be fully used in the wind wheel, thereby improving the use ratio of the wind energy by 20% compared with the turbine wind power generator.

Description

technical field [0001] The present invention relates to a wind power generation device and a wind blade used for the wind power generation device, in particular to a high-efficiency wind power generator provided with a helical turbine blade and provided with the helical turbine blade. Background technique [0002] With the continuous development of the economy, people's demand for energy is increasing, and the reserves of non-renewable resources are seriously threatened. Therefore, people gradually turn their attention to renewable resources. As a clean and renewable energy, wind energy is becoming more and more important. The more and more countries in the world pay attention to it, which promotes the continuous innovation of wind turbines. The existing wind turbines can be divided into horizontal axis type and vertical axis type according to the direction of the rotation axis of their impellers.

[0002] With the continuous development of the economy, people's demand for energy is increasing, and the reserves of non-renewable resources are seriously threatened. Therefore, people gradually turn their attention to renewable resources. As a clean and renewable energy, wind energy is becoming more and more important. The more and more countries in the world pay attention to it, which promotes the continuous innovation of wind turbines. The existing wind turbines can be divided into horizontal axis type and vertical axis type according to the direction of the rotation axis of their impellers. However, the most important components of wind turbines are The wind fins that are directly in contact with the wind energy and provide power for the generator are mostly designed from the aspects of wind gathering and firmness. In order to improve the wind gathering performance, the wind fins need to be enlarged, and the enlargement It will inevitably affect the installation and stability of the wind fins. Although there are many types of wind fins, they are generally equipped with large-area blades or long wind fins to increase their wind gathering performance, and by increasing the wind fin way to increase its power, which often leads to lower installation reliability, more failures, and difficult maintenance
