Abstract

A wind wheel of a vertical axis wind-driven generator in lightweight structure comprises a vertical axis and a plurality of blades on the vertical axis, which is characterized in that an upper wheel disc and a lower wheel disc are arranged on the vertical axis, an upper support wheel rim and a lower support wheel rim are connected with the fixed upper wheel disc and the fixed lower wheel disc via drawing force support bars which are distributed uniformly, a certain included angle is formed between each support bar and the radial direction of the wheel rims, and fan blades are arranged between upper drawing force support bars and lower drawing force support bars. The vertical axis wind-driven generator is characterized by utilizing lightweight sheet materials to produce the fan blades, the fan blade cost is greatly reduced and blade dead weight is lightened, thereby realizing light wind actuation and increasing generating efficiency, further by designed fixed structure of the fan blades, the fan blades are convenient to be changed and maintenance is very convenient. Because of utilizing the lightweight fan blade, a windward angle can be enlarged to a certain extent when a windward side suffering wind, a leeward area can be reduced when a leeward side in leeward, thereby increasing speed of the fan blade.

Description

Light structures vertical axis aerogenerator wind wheel
Technical field
The utility model relates to wind-driven generator, particularly a kind of light structures vertical axis aerogenerator wind wheel, and the cheap and structure weight that is specifically related to adopt soft material or low-intensity material to make designs than the wind wheel that traditional design alleviates significantly.
Background technique
As everyone knows, wind energy is a kind of inexhaustible, nexhaustible energy, and its safety, cleaning, abundant, pollution-free utilize wind-power electricity generation to become the main situation of world today's Wind Power Utilization, be subjected to the very big attention of each country, development is rapid, market potential is huge.
Wind wheel is the critical component of wind-driven generator, and the structural design of wind wheel is most important, is related to the generating effect of entire equipment.
At present, wind-driven generator generally is divided into two kinds of vertical axis aerogenerator and horizontal axis wind-driven generators from the wind wheel form, and horizontal axis wind-driven generator generally exists the wind wheel blade face positively to facing the wind, and the fan blade diameter is big, set up height, fan blade hardness, toughness require defectives such as high fabricating cost costliness.And also there is the high shortcoming of fan blade fabricating cost in the vertical axis aerogenerator that occurs at present, can adopt lighter material more cheaply to make fan blade, reducing fan blade weight, reduce fan blade self rotation loss, realize the gentle breeze starting, is the hot issue of present wind turbines rotor structural design.
Summary of the invention
The purpose of this utility model just at existing problem in the above-mentioned prior art and custom-designed a kind of reasonable in design, simple in structure, fan blade own wt gently and light structures vertical axis aerogenerator wind wheel more low-cost, that can realize the gentle breeze starting.
The purpose of this utility model is achieved through the following technical solutions: this light structures vertical axis aerogenerator wind wheel comprises vertical shaft and a plurality of fan blades that are arranged on the vertical shaft, wherein: vertical shaft is provided with upper and lower fixedly wheel disc, upper and lower support wheel rim all is connected with upper and lower fixedly wheel disc by the radiating type pulling force strut that is evenly distributed, and every pulling force strut all is 0 °~80 ° with the radial direction of wheel rim, is provided with fan blade between upper and lower pulling force strut.
In the utility model, fan blade can be formed by the light sheet material, as: powerful cloth, chemical fibre nylon material, sheet metal, thin stainless steel etc., gentle matter fan blade is arranged between the upper and lower pulling force strut by the fan blade fixed mechanism, and the fan blade fixed mechanism comprises the hollow pole that is sleeved on the pulling force strut, be opened in the groove on the hollow pole outer wall and the draw-in groove rod that is fitted in the groove is formed.
For further improving the stability of whole wind wheel, between vertical shaft top and upper support circle, be connected with brace.
All be set with a draught spring on every pulling force strut, draught spring one end is connected with fixing wheel disc, and the other end is connected with hollow pole in the fan blade fixed mechanism.
The access of generator can be chosen in the access up and down of the vertical shaft of this structure arbitrarily, and the design inserts by the top and is best access way.
Advantage of the present utility model is:
One, make soft material become possibility as fan blade with toughness, can use various light sheet materials, as: powerful cloth, chemical fibre nylon material, sheet metal, thin stainless steel, or the like, when having greatly reduced the fan blade cost, alleviated the fan blade deadweight, realized the gentle breeze driving purposes that progression is lower, and by the fan blade fixed mechanism of design on the fan blade framework, can change fan blade easily, safeguard very convenient.
Two, because this design can insert soft fan blade, so when the wind-engaging of windward side, the angle of facining the wind can have to a certain degree and strengthens, and lee face can reduce the lee face area when leeward, and then the raising wind speed round.
Three, the blade structure of this wind-driven generator also can be designed to separate unit, links together up and down to form the fan blade tower that is made of several unit, further increases the effect of gentle breeze starting, drives more powerful generator.
