Vertical wind power generation system equipped with dual blades and multi-layer reinforced concrete frame

Abstract

A vertical wind power generation system with dual fan blades mounted and a multi-layer reinforced concrete frame. The system solves a problem in a prior wind power generation system that a power generation efficiency thereof and safety of a wind power generator are affected because a wind bearing area of a fan blade is small, a wind power utilization rate is low, wind resistance of a front wing surface is large, a reversing dead angle is large, a large capacity is difficult to achieve, a working capability in a high-wind-speed area and a low-wind-speed area is poor, a working wind area range is small, especially a capability to continuously work in a fierce wind environment is poor, and stability thereof is low, making an overturning moment easily be destroyed by a fierce wind. The system comprises the multi-layer reinforced concrete frame, a movable wind-collection protection system, a fixed extending wind-collection system, a wind power system and a power generation system. The system is a vertical wind power generation system with the reinforced concrete frame, has a high stability and applies to various high- and low-wind-speed areas. The dual combined fan blades can effectively work in high- and low-wind-speed areas. The system is used for a land wind power generation system, and can also be used for an offshore wind power generation system.

Description

technical field [0001] The invention relates to a vertical wind power generation system, in particular to a vertical wind power generation system equipped with dual wind blades and a multi-layer reinforced concrete frame, belonging to the technical field of wind power generation. Background technique [0002] With the occurrence of the world energy crisis, the use of wind kinetic energy as a new energy source has become a hot spot in the development of modern society. The generator set and the speed increaser of the traditional three-bladed wind turbine are installed high above the top of the tower, and the heavy wind blades are hung obliquely on the side, which requires a heavy counterweight. Considering that the wind blades, speed increaser, generator set, counterweight and the heavy engine room have a weight of hundreds of tons, and are supported at high altitude by the tower, when the storm blows, a huge blowing and overturning moment will be generated, because of The f...

AI Technical Summary

Problems solved by technology

[0005] In view of the defects in the prior art, the object of the present invention is to provide a vertical wind power generation system equipped with dual blades and a multi-layer reinforced concrete frame, so as to solve the problem of the small wind-receiving area of ​​the wind blades in the existing wind power generation system and the difficulty of wind power utilization. Low efficiency, large wind resistance on the front wing surface, large reversing dead angle, low wind utilization rate, difficult to increase capacity, poor working ability in high wind speed area and low wind speed area, small working wind area range, especially in the environment of violent wind to continue to work Low capacity and poor stability make the overturning moment easily destroyed by strong winds, thus affecting its power generation efficiency and safety issues
