Description
Technical field:
The utility model relates to the wind-driven generator technical field, more specifically to the air duct structure in the wind-driven generator rotating shaft.
Background technique:
The wind energy resources of China is very abundant, and the electric motor power that can develop is about 2.5 hundred million kilowatts, occupy first place in the world, but the actual wind-power electricity generation electric motor power of China only accounts for 0.11% of national electric power, and the wind-power electricity generation development potentiality is huge.
Be fixed with impeller and air duct on the existing wind-driven generator; Its air duct is generally 3 blade type air ducts or 8 blade type air ducts; Air duct is as the power source of wind-driven generator; Its blade angle difference then utilization ratio to wind is different, and existing 3 blade type air ducts or 8 blade type air ducts still await improving to the utilization ratio of wind.Simultaneously, the air duct in the rotating shaft of wind-driven generator can be provided with the multilayer blade, layer by layer and between layout also utilize wind energy to exert an influence to air duct, existing air duct is because the defective in the design all exists air duct to the not enough problem of Wind Power Utilization.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of six leaf air ducts of wind-driven generator are provided, and it has improved the utilization ratio of air duct to wind energy, has increased the on-the-spot output power of wind-driven generator.
The technological solution of the utility model is following:
Six leaf air ducts of wind-driven generator; Comprise the rotating shaft of wind-driven generator, air duct is made up of individual blade and air duct dish, and individual blade is fixed on the air duct dish; The air duct dish is fixed in the rotating shaft of wind-driven generator; The air duct dish has three and promptly goes up air duct dish, middle air duct dish) and following air duct dish, individual blade two ends of first vane group are separately fixed on air duct dish and the middle air duct dish, and individual blade two ends of second vane group are separately fixed on middle air duct dish and the following air duct dish; The individual blade of first vane group is that six and circular array are in the wind on tube dish and the middle air duct dish, and the individual blade of second vane group is that six and circular array are on middle air duct dish and following air duct dish;
Individual blade is arcuation, and the angle of the tangent line of two individual blades that first vane group is adjacent with second vane group is 25 to 35 degree.
The intrados of the individual blade of the individual blade of said first vane group and second vane group is facing to the direction of wind.
The angle of the tangent line of two individual blades that said first vane group is adjacent with second vane group is 30 degree.
The beneficial effect of the utility model is:
It has improved the utilization ratio of air duct to wind energy, has increased the on-the-spot output power of wind-driven generator.
