Abstract
The invention discloses a fan blade. The fan blade is in an integrated structure and is made of EPP (expanded polypropylene), and a metal framework is arranged in the fan blade. The fan blade is lighter in weight, so that the requirements of strength and rigidity on the design of a fan are reduced, the fan blade can be formed through a mold, the material of the fan blade is relatively cheap, therefore, the fan blade has lower production cost and is more convenient to machine.
Description
Technical field
The present invention relates to a kind of fan blade, particularly a kind of fan blade for wind-power electricity generation.
Background technique
In the situation that fossil energy shortage gradually, green regenerative energy sources is more and more paid attention to by people, and wind-power electricity generation is one of project of tool business promotion prospect.Aero-generator rotor blade (being fan blade) is the critical component of wind power generating set, and it need to meet, and quality is light, the requirement of good rigidity, good weatherability.And current fan blade adopts carbon fiber or metal to make, material is more expensive, and production difficulty is also higher.
Polypropylene plastics foam material (EPP: Expanded polypropylene) be a kind of high Crystalline plastics/gas recombination material, the EPP goods have high, the good heat resistance of recovery rate after excellent antidetonation energy absorption performance, deformation, chemicals-resistant, oil resistance and thermal insulation, in addition, its quality is light, can significantly alleviate Item Weight.EPP or a kind of environment-friendly materials, recyclable recycling not only, and can natural degradation, can not cause white pollution.
Summary of the invention
The technical problem to be solved in the present invention is how a kind of usage requirement that meets is provided, and has cost fan blade low, convenient for production.
For solving the problems of the technologies described above, the invention provides a kind of fan blade, comprise blade and cowling, material is as EPP, and described blade interior is provided with metal frame.
Preferably, described blade and the cowling structure that is formed in one.
Preferably, described blade has a plurality of, the independent moulding of each described blade, and rotating shaft place of described blade is provided with joint and draw-in groove, and described fan blade crosses described joint by a plurality of described blade pass and draw-in groove is spliced.
Preferably, described blade has three.
Compare with existing fan blade, under the requirement that meets rigidity and weatherability, there is lighter quality, reduced the requirement of fan design strength and stiffness.And this fan blade can pass through mould-forming, material is also relatively cheap, thereby has more low production cost, and processing is got up also more convenient.
The accompanying drawing explanation
Fig. 1 is the structural representation of the first mode of execution of fan blade of the present invention.
Fig. 2 is the structural representation of the blade of the fan blade in Fig. 1.
Fig. 3 is the structural representation of the second mode of execution of fan blade of the present invention.
Wherein: 1, blade; 2, cowling; 3, joint; 4, draw-in groove; 5, metal frame.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
The first mode of execution as shown in Figure 1 to Figure 2, comprise blade 1 and cowling 2 that three identical materials of shape are EPP, and blade 1 can be produced by mould-forming.Rotating shaft place of each blade is provided with joint 3 and draw-in groove 4, and the joint 3 of blade 1 and draw-in groove 4 are spliced to form the blade face part of fan blade mutually.In order to strengthen the intensity of fan blade, the inside of blade 1 is inlaid with metal frame 5.
The second mode of execution as shown in Figure 3, the blade 1 of fan blade, cowling 2 structure that is formed in one, material is EPP, its inside is provided with metal frame, to strengthen the intensity of fan blade.
Compare with existing fan blade, under the requirement that meets rigidity and weatherability, there is lighter quality, reduced the requirement of fan design strength and stiffness.And this fan blade can pass through mould-forming, material is also relatively cheap, thereby has more low production cost, and processing is got up also more convenient.
Above mode of execution is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technological schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (4)
1. a fan blade, is characterized in that, comprises blade and cowling, and material is as EPP, and described blade interior is provided with metal frame.
2. fan blade as claimed in claim 1, is characterized in that, described blade and the cowling structure that is formed in one.
3. fan blade as claimed in claim 1, is characterized in that, described blade has a plurality of, the independent moulding of each described blade, and rotating shaft place of described blade is provided with joint and draw-in groove, and described fan blade crosses described joint by a plurality of described blade pass and draw-in groove is spliced.
4. fan blade as claimed in claim 3, is characterized in that, described blade has three.
