Abstract
The invention discloses a propeller of a wind driven generator. The propeller comprises three uniformly distributed impeller blades, wherein the specific value of the height and the width of the blades is (3-5):1, and the top ends or the bottom ends of the blades are designed to be arc-shaped. The face area is increased and starting wind speed is small by adopting the impeller blades; the three impeller blades are uniformly distributed and can directly face wind coming from different directions so that the wind utilization efficiency is greatly improved and can reach above 90%.
Description
Technical field
The present invention relates to technical field of wind power generation, especially a kind of propeller cavitation of wind-driven generator.
Background technique
Wind energy is the inexhaustible clean energy resource that is present in nature, in the situation that existing energy scarcity, the exploitation wind energy is very urgent, and wind energy is the desirable alternative energy source of coal, oil, rock gas simultaneously.Wind energy is that green energy resource can be to environment, and is with low cost, is the desirable energy.
Exploitation to wind energy has had long history, is in the level of original windmill always, and energy conversion rate is low.Pass through in recent years people's effort, the exploitation of wind energy has been had significant raising.China adopts horizontal axis blade wind-driven generator in many areas mostly at present, but its volume is large, blade long, it is inconvenient to install, run into storm wind and very easily topple over, start the wind speed requirement high, the General Requirements wind speed could start greater than 10 meter per seconds, and it is large to take up room, limit using scope, be in all the time maximum wind-receiving face in order to guarantee blade, need add wind plant, so not only increased difficulty but also increased cost, therefore developing new blade is the core work that improves wind-power electricity generation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of propeller cavitation of wind-driven generator, volume is little, start wind-force little, windward effective, easy for installation, use safety.
In order to realize the foregoing invention purpose, the invention provides following technological scheme: a kind of propeller cavitation of wind-driven generator comprises three equally distributed propeller blades; Described blade height and width ratio are 3～5 ︰ 1, and top or the bottom of described blade are made as arc line shaped.
Further, the height of described blade is 0.5～1.3m.
Compared with prior art, the present invention has the following advantages:
1. the employing propeller blade, increase wind-exposuring area large, starts wind speed little; Three propeller blades evenly distribute, can be over against the wind comes from of different direction, and large increase wind utilization ratio can reach more than 90%.
2. blade depth-width ratio scope is little, and blade is small and exquisite, takes up room little, has enlarged using scope.
Description of drawings
Fig. 1 is the structural representation of blade of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of propeller cavitation of wind-driven generator comprises three equally distributed propeller blades 1, as shown in Figure 1; Described blade 1 height and the width ratio is 3～5 ︰ 1, and the top of described blade 1 or bottom are made as arc line shaped 11.The height of described blade 1 is 0.5～1.3m.
The propeller cavitation of wind-driven generator adopts three equally distributed blades, and therefore manage-style from which direction does not blow and can promote blade, makes the generator shaft rotation, because blade is spirality, has greatly increased blade area windward.The blade upper and lower end adopts the arc design, reduces resistance, improves its efficient.
Claims (2)
1. the propeller cavitation of a wind-driven generator, is characterized in that: comprise three equally distributed propeller blades; Described blade height and width ratio are 3～5 ︰ 1, and top or the bottom of described blade are made as arc line shaped.
2. the propeller cavitation of wind-driven generator as claimed in claim 1, it is characterized in that: the height of described blade is 0.5～1.3m.
