Abstract

The utility model relates to a wind power generation blade, which comprises a rotation shaft body, a plurality of blades which are distributed on the periphery of the rotation shaft body at equal interval with the rotation shaft body serving as the centre of a circle and at least one turbulent flow portion. Each blade comprises a windward side and a leeward side, each windward side is provided with a wind outlet area and a wind inlet area which receives wind and is far away from the wind outlet area, and the turbulent flow portion is arranged in the wind outlet area. When the blade rotates, the turbulent flow portion has the wind resistance effect to enable the wind to be free of rapid flowing to promote force to promote the blade to rotate, and a generator is effectively driven to generate electric energy.

Description

Wind power generation blade

Technical field

The utility model relates to blade, and particularly a kind of tool choke effect gets and effectively drives the wind power generation blade that generator produces electric energy.

Background technique

Wind-driven generator can be installed in significantly coastal area of wind-force substantially, mainly is that the wind speed through the gas natural wind is that kinetic energy blows the blade rotation, and the kinetic energy strength rotating generator through the blade rotation produces electric power.Because it is different with the Blade Design of general air-supply usefulness to be applied in the blade of wind-power electricity generation; The blade of general air-supply usefulness is to utilize the electric power rotation blade producing aerodynamic energy, and the blade structure of wind-power electricity generation is to bear aerodynamic energy to convert aerodynamic energy into mechanical energy and export with electric energy.Therefore to wind power generation blade, need the kinetic energy of effective application nature wind speed, the structure through blade converts gas kinetic energy into electric energy, more effective drive generator produces electric energy.

The model utility content

The main purpose of the utility model provides a kind of sharp power generation blade, is the structural design through this blade, must promote to promote this blade Power of Spin and can promote this blade rotatory inertia, more effectively drives generator and produces electric energy.

For reaching above-mentioned purpose, the utility model provides following technological scheme:

The utility model is a kind of wind power generation blade; Include: a rotation axis body, a plurality of be the center of circle and with this rotation axis body to be equally spaced at blade and at least one spoiler in this external week of running shaft; This leaf packet contains a windward side and a lee face; This windward side has that a wind outlet area and is accepted wind-force and away from the inlet air district of this wind outlet area, this spoiler is arranged at this wind outlet area.

Further, have between the windward side of this blade of the utility model and this lee face and be installed in one of a liquid and be installed with the space.

Further, contiguous this running shaft position of this blade of the utility model is changed to hollow, is installed with the space and establish this away from this rotation axis body.

Further, this liquid of the utility model is one of them of liquid, powder or spheroid.

Further, this liquid of the utility model is installed in this volume that is installed with the space and is installed with 1/2～1/3 of spatial content for this.

Further, this spoiler of the utility model is protruding granular, and arranges with a plurality of one-tenth one and to be located at this wind outlet area.

Further, this spoiler of adjacent two rows of the utility model is for being laid staggeredly in this wind outlet area.

Further, this spoiler of the utility model is and the rectangular groove of this wind outlet area with length direction, and arranges with a plurality of one-tenth one and to be located at this wind outlet area.

Further, this spoiler of the utility model serve as reasons this wind outlet area outwards bending extend a width and constitute.

The utlity model has following advantage and good effect:

Adopt the wind power generation blade of the utility model design, this spoiler has the choke effect wind-force is not flowed out rapidly when this blade rotation, must promote promoting this blade Power of Spin, effectively drives generator and produces electric energy.

In addition, the liquid that is housed in this blade flows along with this blade rotates and the change position, makes this blade promote the inertia that continues rotation because of receiving Gravity changer, reaches enhancement wind-force benefit, can further drive generator and produce electric energy.

Embodiment

About technology contents, characteristics and the effect of the utility model, below cooperate to be elaborated with reference to accompanying drawing and preferred embodiment.

See also Fig. 1～shown in Figure 3, be respectively the utility model first embodiment's schematic perspective view, planimetric map and sectional drawing, the utility model is a kind of wind power generation blade, includes: rotation axis body 10, a plurality of blade 20 and an at least one spoiler 21.

This blade 20 in the present embodiment is three; And be that the center of circle is equally spaced in the periphery of this rotation axis body 10 with this rotation axis body 10, this blade 20 includes a windward side 22 and a lee face 23, has between this windward side 22 and this lee face 23 to be installed in one of a liquid 24 and to be installed with space 25; This liquid 24 is one of them of liquid, powder or spheroid; This blade 20 contiguous these rotation axis body 10 positions are hollow, are installed with space 25 to be installed in this liquid 24 and establish this away from this rotation axis body 10, and the center of gravity that makes this blade 20 is partially in the periphery of this blade; It is preferable for this is installed with 1/2～1/3 of space 25 capacity that this liquid 24 is installed in this volume that is installed with space 25; And this windward side 22 has that a wind outlet area 26 and is accepted wind-force and away from the inlet air district 27 of this wind outlet area 26, this spoiler 21 is arranged at this wind outlet area 26, and this spoiler 21 is protruding granular; And arrange with a plurality of one-tenth one and to be located at this wind outlet area 26, and this spoiler 21 of adjacent two rows is for being laid staggeredly in this wind outlet area 26.

Please consult shown in Figure 4ly again, be the utility model second embodiment's schematic perspective view.This spoiler 21a is and the rectangular groove of this wind outlet area 26 with length direction in the present embodiment, and arranges with a plurality of one-tenth one and to be located at this wind outlet area 26, and this spoiler 21a of adjacent two rows is for being laid staggeredly in this wind outlet area 26.

Please consult shown in Figure 5ly again, be the utility model the 3rd embodiment's schematic perspective view.In the present embodiment this spoiler 21b serve as reasons this wind outlet area 26 outwards bending extend a width and constitute, and the angle of this spoiler 21b and this blade 20 is about 75 and spends.
