Abstract
The invention relates to a wind driven generator blade, in particular to a saw teeth auxiliary beam wind driven generator blade. The saw teeth auxiliary beam wind driven generator blade comprises a blade shell, a blade root, a reinforcing root plate, a main beam and auxiliary beams. The outer surface of the blade is the blade shell, the most root portion is the blade root, the reinforcing root plate is arranged at the upper end of the blade root, the main beam extends from the blade root to the tip portion of the blade shell, the auxiliary beams are arranged at two sides of the main beam and are distributed symmetrical about the main beam. Compared with other similar products, the saw teeth auxiliary beam wind driven generator blade has the advantages of being simple in structure, stable in structure, capable of saving material and high in fatigue resistant performance.
Description
Technical fieldThe present invention relates to a kind of blade of wind-driven generator, concrete relate to a kind of Sawtoothed auxiliary beam wind turbine generator blade.
Background techniqueAt present, because the critical shortage of social resources, people tend to the exploitation to renewable resources gradually.Especially be wind resource, people are for better more effective by wind resource, thereby take various measures to realize wind power utilizations.Effective method is the utilization to wind-driven generator.As everyone knows, wind-driven generator is by driving blade rotary by natural wind and then power supply is provided, and it can be used as requisite equipment in the wind generating technology.Yet, the choosing of wind-driven generator, key is blade, thereby the selection of blade of wind-driven generator is most important.At present, known blade of wind-driven generator is selected i-shaped beams or rectangular beam mostly, and blade interior adopts the staggered reinforcement bar of horizontal and longitudinal direction.The advantage of this structure shows that blade structure is compact, more stable, makes the weight of blade own strengthen, waste material but shortcoming is inner reinforcing bar design, and cost strengthens, and does not satisfy people's demand.
Summary of the inventionThe present invention is in order to remedy above-mentioned technological deficiency, a kind of Sawtoothed auxiliary beam wind turbine generator blade to be provided.
Technological scheme of the present invention is: Sawtoothed auxiliary beam wind turbine generator blade comprises: sheet shell, root of blade, enhancing root plate, girder and floor stringer; Blade outer surface is the sheet shell, and bottommost is root of blade, is provided with the enhancing root plate in the root of blade upper end, and girder extends to sheet shell apical location from root of blade, in the girder both sides floor stringer is set, and is symmetric about girder.
Described floor stringer indention, and the sawtooth angle is 30 degree.
Beneficial effect of the present invention is: compare with other like products, simple in structure, structural stability is saved material, and is had higher fatigue resistance.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1, the sheet shell, 2, root of blade, 3, the enhancing root plate, 4, girder, 5, floor stringer.
Embodiment
Fig. 1 shows a kind of Sawtoothed auxiliary beam wind turbine generator blade schematic diagram.Comprise: sheet shell 1, root of blade 2, enhancing root plate 3, girder 4 and floor stringer 5; Blade outer surface is sheet shell 1, and bottommost is root of blade 2, is provided with enhancing root plate 3 in root of blade 2 upper ends, and girder extends to sheet shell 1 apical location from root of blade 2, in girder 4 both sides floor stringer 5 is set, and is symmetric about girder 4.Described floor stringer 5 indentions, and the sawtooth angle is 30 degree.Root of blade 2 and strengthen adopting between the gusset 3 Bond to be fixed has played the effect of protection root of blade 2, thereby prolongs blade working life.
Claims (2)
1. Sawtoothed auxiliary beam wind turbine generator blade is characterized in that comprising: sheet shell, root of blade, enhancing root plate, girder and floor stringer; Blade outer surface is the sheet shell, and bottommost is root of blade, is provided with the enhancing root plate in the root of blade upper end, and girder extends to sheet shell apical location from root of blade, in the girder both sides floor stringer is set, and is symmetric about girder.
