Abstract
The invention discloses a connecting and supporting hoop structure for vertical axis fan blades. The connecting and supporting hoop structure comprises blades, supporting rods and hoop pieces, wherein the supporting rods are fixed to one ends of the hoop pieces, the blades are arranged at the outer ends of the supporting rods, and the two hoop pieces are connected in a matched mode through concave and convex structures arranged on the hoop pieces respectively. The combination connection of the device is trapezoidal surface concave and convex connection, and thus the reliability of the connecting hoops is improved. Meanwhile, because the structure is simple, manufacturing work efficiency is improved, and cost is greatly reduced.
Description
?
Technical field
Hooping structure is supported in the connection that the present invention relates to a kind of vertical shaft fan blade.
Background technique
The combination of the connection of general common blade and support hooping structure connects because of complex structure, manufactures work efficiency low, and cost is also large.Can not get popularizing.And strut partly adopts round and square material, does not meet aerodynamic requirement.At the three-dimensional spiral curved surface that connects the blade of can not effectively fitting with blade, and processed complex, work efficiency is low, and cost is high.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of connection of vertical shaft fan blade to support hooping structure.This structure adopts advanced three dimensional design, and the analysis of the line space of going forward side by side aerodynamic properties, after revising and improving.With GB 102 aluminum alloy material, through die casting, form.Strut cross section external form is airfoil structure, coordinates completely with blade surface of contact.Solve the connection of general common blade and the problem of support hooping structure.
The present invention for achieving the above object, adopt following technological scheme: hooping structure is supported in a kind of connection of vertical shaft fan blade, comprise blade, strut and anchor ear part, described strut is fixed and described anchor ear part one end, described blade is located at described strut outer end, on two described anchor ear parts by the concaveconvex structure the being respectively equipped with connection that cooperatively interacts.
Preferably, the outer end surface of contact of described blade is spiral camber.
Preferably, described strut cross section is aerofoil section.
Beneficial effect of the present invention: the combination of this device connects for the concavo-convex connection of trapezoidal faces, improves the reliability that connects anchor ear, simultaneously because of simple in structure, manufacture work efficiency and improves, and cost also reduces greatly.Wherein, strut cross section is aerofoil profile, better meets aerodynamics and hydromechanical requirement.Blade surface of contact is that spiral camber meets exterior design technological requirement, and not only handsome in appearance, quality of product is also improved.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
Embodiment
Hooping structure is supported in the connection that Figure 1 shows that a kind of vertical shaft fan blade, comprise blade 2, strut 1 and anchor ear part 3, described strut 1 is fixed and described anchor ear part 3 one end, described blade 2 is located at described strut 1 outer end, on two described anchor ear parts 2 by the concaveconvex structure the being respectively equipped with connection that cooperatively interacts.The outer end surface of contact of described blade 2 is spiral camber.Strut 1 cross section is aerofoil section, better meets aerodynamics and hydromechanical requirement.
Anchor ear part 3 is wherein that two identical symmetrical installations of aluminum alloy die casting of appearance structure combine.
Structural member of the present invention is simple, connects reliably, manufactures work efficiency high, and cost is low.Can be widely used in 40W, 100W, the connection of the vertical axis aerogenerator spiral camber type blade of 1000W to 5000W and support anchor ear.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
