Embodiment 1

[0035] Such as figure 1 As shown, in the present invention, one side of the wind gathering surface is higher than the other side, so that the fan blades are positioned at the low surface. The wind above the blades is gathered to increase the air volume, thereby increasing the efficiency of the fan or wind generator.

Embodiment 2

[0037] Such as figure 2 As shown, the wind gathering surface of the present invention is a concave structure with a high perimeter and a low middle, so that the fan blades are located in the middle, so that the wind from any direction can achieve the effect of increasing the air volume.

Embodiment 3

[0039] Such as image 3 As shown, in the present invention, at least one side of the wind collecting surface is lower than the other side, and when the wind blows from the direction of the low surface to the direction of the high surface, the wind collecting surface will gather the wind passing under the fan blades , to increase the air volume, thereby improving the efficiency of the fan or wind generator.

Abstract

The invention discloses a device for increasing air volume and improving fan efficiency, which is characterized in that it is composed of one or more pillars supporting one or more wind collecting surfaces, at least one side of the wind collecting surfaces is higher or lower than on the other side. The present invention can greatly improve the efficiency of wind power generation with a slight increase of a little investment on the basis of the existing wind farm, and the present invention can also double the wind power without changing the fan or wind power generator equipment. Increase power generation. The invention can also effectively protect the wind turbine or wind power generator equipment from the erosion of wind and rain, thereby improving the service life of the wind turbine or wind power generator equipment.

Description

1. Technical field [0001] The invention belongs to the technical field of wind energy utilization, and is especially applicable to the technical fields of wind power machinery and wind power generation. 2. Background technology [0002] With the rapid development of the world economy and fierce competition, new energy power generation technology, especially wind power generation technology, has attracted more and more attention from all countries in the world. At present, the installed capacity of wind power in the world has reached 4.9 million kilowatts, and it is still growing at an average annual rate of 60%, reflecting a new trend in the development of international electric power. my country has abundant wind energy resources, and foreign mature technologies can be used for reference. The conditions for large-scale development of wind power have been met and should be actively developed. However, at present, the high cost of wind power has hindered the further developm...
