Abstract
The invention discloses a six-blade air duct of a wind generator. Single blades are fixed on air duct disks, and the air duct disks are fixed on a rotating shaft of the wind generator; the number of the air duct disks is three, namely the upper air duct disk, the middle air duct disk and the lower air duct disk; two ends of the single blades of the first blade group are respectively fixed on the upper air duct disk and the middle air duct disk, and two ends of the single blades of the second blade group are respectively fixed on the middle air duct disk and the lower air duct disk; the number of the single blades of the first blade group is six, and the six blades are arranged on the upper air duct disk and the middle air duct disk in an annular array; the number of the single blades of the second blade group is six, and the six blades are arranged on the middle air duct disk and the lower air duct disk in an annular array; and the single blades are arc-shaped, and the included angle of the tangents of the two adjacent single blades of the first blade group and the second blade group is 25 to 35 degrees. The wind energy utilization efficiency of the air duct is improved, and the field output power of the wind generator is increased.
Description
Technical field:
The present invention 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.
Summary of the invention:
The object of the invention 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.
Technological solution of the present invention 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.
Beneficial effect of the present invention 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.
Description of drawings:
Fig. 1 is a schematic perspective view of the present invention
Fig. 2 is the schematic perspective view of air duct
Fig. 3 is the layout schematic representation of the blade on the air duct
Among the figure: 1, the rotating shaft of wind-driven generator; 2 air ducts; 21, individual blade; 22, air duct dish; 221, go up the air duct dish; 222, middle air duct dish; 223, following air duct dish; 3, first vane group; 4, second vane group.
Embodiment:
Embodiment: see shown in Fig. 1 to 3; Six leaf air ducts of wind-driven generator; Comprise the rotating shaft 1 of wind-driven generator, air duct 2 is made up of individual blade 21 and air duct dish 22, and individual blade 21 is fixed on the air duct dish 22; Air duct dish 22 is fixed in the rotating shaft 1 of wind-driven generator; Air duct dish 22 has three individual blade 21 2 ends of promptly going up air duct dish 221, middle air duct dish 222 and following air duct dish 223, the first vane group 3 to be separately fixed on air duct dish 221 and the middle air duct dish 222, and individual blade 21 2 ends of second vane group 4 are separately fixed on middle air duct dish 222 and the following air duct dish 223;
The individual blade 21 of first vane group 3 is that six and circular array are in the wind on tube dish 221 and the middle air duct dish 222, and the individual blade 21 of second vane group 4 is six and circular array on middle air duct dish 222 and following air duct dish 223;
The intrados of the individual blade 21 of said first vane group 3 and the individual blade 21 of second vane group 4 is facing to the direction of wind.
