5mm, the specific value about L can be according to the specifications and models adjusted design of blade 100.
In some embodiments of the utility model, as depicted in figs. 1 and 2, protrusion 3 is flexible piece and elongated, convex
It plays 3 one end to be connected with blade body 1, raised 3 other end is free end.As a result, by making protrusion 3 be formed as strip,
Be conducive to increase the closeness of the protrusion 3 on blade 100, to enhance the perturbation action of protrusion 3, to be conducive to destroy big ruler
The formation of very little vortex, and the lesser spiral structure of size is generated, vortex energy is smaller, and then reduces aerodynamic loss, reduces vortex
Noise.Certainly, the utility model is without being limited thereto, and protrusion 3 can also be hard material, such as protrusion 3 is miniature burr.
Optionally, as shown in Figure 1, the blade 100 of wind wheel includes: connector 2, connector 2 is the flexible piece of sheet and covers
It covers at least part surface of blade body 1, multiple raised 3 are located on connector 2.Wherein, " connector 2 is covered on leaf
On at least part surface of piece ontology 1 " it can be understood as connector 2 and be covered on a part of surface of blade body 1, or
Connector 2 is covered on all surfaces of blade body 1.As a result, by being located at multiple raised 3 on connector 2, and connector
2 are covered at least part surface of blade body 1, and it is strong to be thus conducive to the connection improved between protrusion 3 and blade body 1
Degree, and the connection being easy to implement between protrusion 3 and blade body 1.For example, protrusion 3 is villus, connector 2 is velour leather, Ke Yili
Solution, the villus and velour leather itself of blade body 1 also have certain sound-absorbing effect, can further decrease and work in wind wheel
When wind wheel caused by noise.
In some optional embodiments of the utility model, as shown in Figure 1, connector 2 is bonded in blade body 1.
Be conducive to further increase the bonding strength between protrusion 3 and blade body 1 as a result, and by setting connector 2, be convenient for
Realize the connection between protrusion 3 and blade body 1.For example, connector 2 can be bonded by adhesive, hot melt adhesion or solvent are viscous
It the modes such as connects to be adhered in blade body 1.
In some embodiments of the utility model, protrusion 3 is integrally formed with blade body 1.As a result, protrusion 3 with
Blade 100 facilitates molding, is simple to manufacture, and eliminates extra assembly parts and connection process, substantially increases blade 100
Production efficiency.
In some embodiments of the utility model, as shown in Figure 1, multiple raised 3 be in rectangular arrangement.It is advantageous as a result,
Multiple raised 3 perturbation actions in enhancing blade body 1 to be conducive to destroy the formation of large scale vortex, and generate
The lesser spiral structure of size, vortex energy is smaller, and then reduces aerodynamic loss, reduces vortex noise.
It is shown referring to Figures 1 and 2 in some embodiments of the utility model, raised 3 extending direction and the stream of air-flow
Dynamic direction is perpendicular or parallel, and in other words, the extending direction that can be protrusion 3 is vertical with the flow direction of air-flow, or can also be with
Be protrusion 3 extending direction it is parallel with the flow direction of air-flow.It should be noted that the extending direction of protrusion 3 refers to that protrusion 3 exists
Extending direction when static, i.e., the extending direction of protrusion 3 when wind wheel does not rotate.For example, protrusion 3 is made by flexible material, in wind
When wheel does not rotate, the extending direction of protrusion 3 is vertical with the flow direction of air-flow, when wind wheel rotation, as shown in Figure 1, protrusion 3
Extending direction changes, and protrusion 3 extends under the action of air-flow towards the downstream of air-flow.Be conducive to destroy big ruler as a result,
