Abstract

The present invention relates to a kind of novel blade structure with simple production process for vertical shaft wind power generator. The blade has simple structure, high rigidity and high wind energy utilizing coefficient. The blade structure consists of three sections with connecting fin(s).

Description

A kind of vane of vertical shaft wind-driven generator structure
Affiliated technical field
The present invention relates to a kind of novel structure, the simple vertical axis aerogenerator extruding of production technology blade structure.This vertical axis aerogenerator extruding blade structure good rigidity, power coefficient height.
Background technique
At present, the monolithic extruded forming method of the existing general employing of vertical axis aerogenerator extruding blade structure, this integral forming method needs the large-size extruder tool, has therefore limited the low-cost production in enormous quantities of this generator extruding blade.
Summary of the invention
For the difficulty that overcomes the moulding of existing vertical axis aerogenerator extruding blade integral, enhance productivity and the utilization ratio of structural material, the invention provides a kind of novel structure, stock utilization height, the simple vertical axis aerogenerator extruding of production technology blade splicing structure.
The technical solution adopted for the present invention to solve the technical problems is: vertical axis aerogenerator is pushed blade along the tangential plurality of sections that is divided into, and each section is provided with the used dovetail groove of connection; Produce each section with the less extrusion machinery of scale, by dovetail groove each section coupled together then.
The invention has the beneficial effects as follows: the vertical axis aerogenerator produced extruding blade, simple for structure, stock utilization is high, production technology is simple, structural rigidity is good.
Further specify specific structural features of the present invention below in conjunction with Figure of description and embodiment.
Brief Description Of Drawings:
Fig. 1 is an overall pattern of the present invention, and 1 is first section in blade among the figure, the 2nd, and second section in blade, the 3rd, the 3rd section in blade, the 4th, the connecting sheet on first section in the blade, the 5th, the connecting sheet on second section in the blade, the 6th, the connecting sheet on second section in the blade, the 7th, the connecting sheet on the 3rd section in the blade.
Fig. 2 is first section sectional view of blade of the present invention, and 1 is first section in blade among the figure, the 4th, and the connecting sheet on first section in the blade.
Fig. 3 is second section sectional view of blade of the present invention, and 2 is second section in blades among the figure, and 5 and 6 is the connecting sheets on second section in the blade.
Fig. 4 is the 3rd a section sectional view of blade of the present invention, and 3 is the 3rd section in blades among the figure, the 7th, and the connecting sheet on the 3rd section in the blade.
Embodiment
Shown in Fig. 2,3,4, first section, second section and the 3rd section of the extrusion modling blade respectively; With mode shown in Figure 1 each section blade pass being crossed dovetail groove again couples together and promptly can be made into a kind of vane of vertical shaft wind-driven generator structure.

Claims (1)

1. vane of vertical shaft wind-driven generator structure, it is characterized in that: whole blade is along the tangential plurality of sections that is divided into; Connect by dovetail groove between every section.
