Abstract
The invention discloses a kind of blade structure for wind driven generator based on laser micropore technology, including blade, steel wire, laser micropore and central shaft, the central shaft through blade center line and be fixedly connected with blade.Blade structure for wind driven generator based on laser micropore technology, by laterally beating micropore with laser in blade surface so that air-flow is in the front face area by not changing blade during blade surface；When passing through blade surface, fraction is exported air-flow by micropore, and air-flow generates downward component to blade when passing through micropore, be ensure that blade will not disable in high speed rotation due to ascending air increases, is effectively reduced climbing power of the wind energy conversion system in high rotating speed.
Description
Technical field
The present invention relates to electrical equipment technical field, specially a kind of blade of wind-driven generator based on laser micropore technology
Structure.
Background technology
Wind-driven generator is to convert wind energy into mechanical work, the power equipment of final output alternating current, in a broad sense, wind energy
It is also solar energy, is a kind of green energy resource, is more and more used by exploitation, the power generation of wind-driven generator is the work by wind-force
With blade of wind-driven generator being driven to rotate, and then generator amature rotation is driven to produce electricl energy, since blade of wind-driven generator exists
Certain climbing power can be generated when rotation, so as to which certain energy can be lost in because of the increase of ascending air, is reduced
The conversion ratio of wind energy.
Invention content
The purpose of the present invention is to provide a kind of blade structure for wind driven generator based on laser micropore technology, in solution
State the problem of being proposed in background technology.
To achieve the above object, the present invention provides following technical solution：A kind of wind-power electricity generation based on laser micropore technology
Machine blade construction, including blade, steel wire, laser micropore and central shaft, the central shaft through blade center line and and leaf
Piece is fixedly connected.
Preferably, the blade is twist.
Preferably, the back insertion of the blade is provided with more than one steel wire.
Preferably, the blade surface is provided with laser micropore, the vertical cross section of the laser micropore and blade into
It is lower to tilt 60 degree of settings.
Compared with prior art, the beneficial effects of the invention are as follows：The blade of wind-driven generator based on laser micropore technology
Structure, by laterally beating micropore with laser in blade surface so that air-flow during blade surface by not changing blade windward
Area；When passing through blade surface, fraction is exported air-flow by micropore, and air-flow generates downwards when passing through micropore to blade
Component ensure that blade will not disable in high speed rotation due to ascending air increases, effectively reduce wind energy conversion system in high rotating speed
When climbing power.
Description of the drawings
Fig. 1 is structure diagram provided by the invention；
Fig. 2 is the sectional view of blade provided by the invention.
In figure：1- blades, 2- steel wires, 3- laser micropores, 4- central shafts.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of wind-driven generator leaf based on laser micropore technology
Chip architecture, including blade 1, steel wire 2, laser micropore 3 and central shaft 4, the central shaft 4 through blade 1 center line and with
Blade 1 is fixedly connected, and twist, blade 1 rotates the blade 1 under the action of the forces of the wind, and then central shaft 4 is driven to rotate,
Central shaft 4 is acted on generator, and so as to generate electricity, 1 surface of blade is provided with laser micropore 3, the laser micropore 3
Vertical cross section with blade 1 is into tilting down 60 degree of settings so that air-flow during 1 surface of blade by not changing blade 1
Front face area, when by 1 surface of blade, fraction is exported air-flow by laser micropore 3, when air-flow is by laser micropore 3
Downward component is generated to blade 1, ensure that blade 1 will not disable in high speed rotation due to ascending air increases, effectively drop
Low climbing power of the wind energy conversion system in high rotating speed, the back insertion of the blade 1 are provided with more than one steel wire 2, improve leaf
The intensity of piece 1, and then improve the service life of blade 1.
Operation principle：Laser micropore 3 is set on 1 surface of blade so that air-flow during 1 surface of blade by not changing blade
1 front face area, when by 1 surface of blade, fraction is exported air-flow by laser micropore 3, and air-flow passes through laser micropore 3
When downward component is generated to blade 1, ensure that blade 1 will not disable when ascending air increases in high speed rotation, effectively
Reduce climbing power of the wind energy conversion system in high rotating speed.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc.
With replacing, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection domain of invention.
