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

Abstract

The invention provides a vertical type wind power generation system provided with dual blades and a multi-layer reinforced concrete frame. The vertical type wind power generation system aims to solve the problem that in an existing wind power generation system, the wind bearing area of blades is small, the wind power utilizing rate is low, wind resistance of the front wind surface is large, a reversing angle is large, large capacity is achieved difficultly, work ability in a high-wind-speed area and a low-wind-speed area is poor, a work wind area range is small, poor continuous work ability and poor stability of the existing wind power generation system in a fierce-wind environment affect the overturning moment of force so that the existing wind power generation system can be blown to be damaged easily, and therefore electricity generation efficiency and safety of the existing wind power generation system are affected. The vertical type wind power generation system comprises the multi-layer reinforced concrete frame, a moving wind-collecting protective system, a fixed extending wind-collecting system, a wind power system and an electricity generating system. The vertical type wind power generation system with the reinforced concrete frame is extremely high in stability, and suitable for various high-wind-speed areas and low-wind-speed areas, and the dual combination blades can effectively work in the high-wind-speed areas and the low-wind-speed areas. The vertical type wind power generation system is used for land wind power generation systems, and can also be used for offshore wind power generation systems.

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...

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
