Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0014] Such as figure 1 As shown, a one-way open blade vertical axis wind power generation system includes a generator set 1, a windmill bracket and a power transmission shaft 2, and three blades 3 fixed on the windmill bracket and the power transmission shaft 2. The blade 3 includes a Each grid 32 of the grid-shaped frame body 31 is connected with a small blade 33 capable of opening in one direction, and the small blade 33 is connected with the frame body 31 through a hinge.

[0015] When the blade 3 rotates against the wind, since the small blade 33 opens upward without any obstruction on one side, the resistance of the blade 3 is the smallest. Push the blower fan to r...

Abstract

The invention relates to the filed of wind power generation, and aims to provide a vertical axis wind power generation system with unidirectional-opening type blades. The vertical axis wind power generation system has the beneficial effects that the wind area is increased, the wind power generation system is suitable for the manufacture of high-power fans, the flexibility is improved, and the utilization rate of wind energy is improved. The wind power generation system comprises a generator unit, a windmill bracket, a power transmission shaft and a plurality of blades, wherein the blades are fixedly arranged on the windmill bracket and the power transmission shaft, each blade comprises a lattice-shaped frame body, and each lattice of the frame body is connected with a unidirectional-opening type small blade. Compared with the original other vertical axis wind power generation systems, the vertical axis wind power generation system has the advantages that the wind area is effectively and greatly increased, so the output power and the utilization rate of the wind energy are greatly improved; the structure is simple, the cost is low, the wind power generation system can be manufactured into a large or ultra-large wind power generation system, the output power can be flexibly controlled, and the safety of the fans can be improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a one-way open blade vertical axis wind power generation system. Background technique [0002] The fans of wind power generation are divided into horizontal axis and vertical axis. Compared with traditional horizontal axis wind turbines, vertical axis wind turbines have many advantages such as advanced design methods, high utilization rate of wind energy, low start-up wind speed, and no noise. Broad market application prospects. At present, the blades of vertical axis fans are mainly Ф-type and H-type, and there are other shapes. The main disadvantages are that the wind receiving area is small, the power is not large, and the utilization rate of wind energy is low. Therefore, it is necessary to use the principle of one-way air duct, the principle of grid separation, and the technology of track support to solve the composition problem of the fan, and improve the shape and str...
