Spiral turbine blade and vertical axis spiral turbine blade wind-driven generator

Abstract

The invention relates to a spiral turbine blade and a wind-driven generator. The spiral turbine blade is sleeved on a rotor and comprises a cylindrical wind wheel body and at least two blades arranged on the wind wheel body, wherein the blades are spirally distributed on the wind wheel body at uniform and equidistant intervals; and the blades are bulges formed on the wind wheel body, and the blades are gradually thinned from the root to the outside. The wind-driven generator comprises an upright post, a vertical axis wind-driven generator arranged on the upright post, and the spiral turbine blade sleeved on the generator, wherein the end of the blade is provided with an air trap plate. The blade has a more stable structure, is firm and durable, has good wind gathering effect and does not generate rotation resistance; due to the adoption of a spiral structure, the rotation resistance is reduced, convection of wind is facilitated, and a yawing device is unnecessary; and wind energy can be fully used in wind wheels, and the wind energy utilization ratio of the wind-driven generator is improved by 20 percent compared with that of a turbine wind-driven generator.

Description

[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
