Single-wheel multi-blade upright wind paddle-type wind wheel for wind power generation

Abstract

The invention provides a single-wheel multi-blade upright wind paddle-type wind wheel for wind power generation, which has high efficiency and is not influenced by an air flow direction. The single-wheel multi-blade upright wind paddle-type wind wheel consists of paddle wings, a paddle arm, a wind wheel shaft and a bracket, and is characterized in that the paddle wings are parallel to the wind wheel shaft, and are fixedly connected with the wind wheel shaft through the paddle arm; more than two paddle arms are arranged; the heads of the paddle wings are in outward-bent circular arc shapes; the middle parts of the paddle wings are planes; and the tails of the paddle wings are bent inwards. The single-wheel multi-blade upright wind paddle-type wind wheel can generate more balanced directed power without being influenced by the flow direction, improves the wind power efficiency and reduces the self anti-resistance of the own energy consumption simultaneously, has a small volume space, and is widely suitable for wind power generation or wind power generation small household equipment.

Description

technical field [0001] The invention relates to a wind power generation device, which is a wind power generation single-wheel multi-blade upright wind paddle type wind wheel with high efficiency and not limited by the direction of air flow. Background technique [0002] At present, most large or small wind power generators are in the form of coaxial blade generators with generators and blades, which is similar to the power generation of electric fans, hereinafter referred to as electric fans. The volume of the wind power blade system in the form of an electric fan is relatively large, and there are requirements for the direction of the wind. In large-scale systems, there are not only certain requirements on the direction of the wind direction, but also through the change of the wind vane, the windward side of the fan is also adjusted through electronic control. At the same time, there are also requirements for the changeable angle of the angle of its own blades. The change ...

AI Technical Summary

Problems solved by technology

When the small machine is windy, the speed is high, the noise is loud, and it is dangerous to be close to the ground or objects

As far as the miniaturized fan is concerned, due to its high speed and relatively low torque, the electronic control function of the gear with variable blade angle will increase the cost and cannot realize the economic value of the market

Most of the water turbines are still in the form of turbofans, which are similar to electric fans, and are not suitable for occasions where the flow rate and flow direction are changeable.
