Abstract
The utility model discloses an S-shaped wind power generation blade comprising two curved surface portions in tangent arrangement. The two curved surface portions in tangent arrangement allow the blade to be made in an S shape. The blade can be rotated towards a single direction without adjusting the angle of the blade with an auxiliary device regardless the wind direction. The wind power generation blade is simple in structure and low in cost. The blade can be rotated towards a single direction regardless the wind direction, which improves the wind receiving area of the blade and increases the power output. When in use, the blade is perpendicular to the ground, the center of mass of the blade is near the ground, and the suspension height of the blade is low. The blade is simple for installation and fixing. When the wind power generation power has to be increased, the wind receiving area can be substantially increased by increasing the length of the blade.
Description
Technical field
The utility model relates to a kind of blade for wind-power electricity generation.
Background technique
Along with the fast development of human society, the demand of the energy is sharply increased, original mineral source reduces day by day, and fossil energy harm that environment is caused, forces people to research and develop, use wind energy.
The kinetic energy of keeping watch is transformed into mechanical energy, then mechanical energy is converted into electric energy, Here it is wind-power electricity generation.The principle of wind-power electricity generation is: utilize wind-force to drive wind wheel rotation, then by speed increasing mechanism, the speed of rotation is promoted and impels generator generating.Common wind generating unit comprises head, turns, empennage, wind wheel.Wind wheel is used for accepting wind-force and transfers electric energy to by head.Thereby empennage is used for making wind wheel facing to the direction of the wind comes from, to obtain maximum wind energy all the time.Turn and for head is rotated neatly, realize the function of empennage adjustment direction.The rotor of head is permanent magnet, and stator cutting magnetic line produces electric energy.
Because existing wind generating unit must arrange empennage, therefore, existing wind power generation device structure is quite complicated, and cost is high.
Model utility content
The utility model provides a kind of blade for wind-power electricity generation, and it has overcome the existing deficiency of background technique.The utility model solves the technological scheme that its technical problem adopts:
For a blade for wind-power electricity generation, it is characterized in that: S-shaped shape, comprises two curvature portions, these two tangent settings of curvature portion.
Among one preferred embodiment: the sectional shape of this curvature portion is half-circle-arc shape.
Among one preferred embodiment: this blade is one-body molded.
The technical program is compared with background technique, and its tool has the following advantages:
1. described in, blade comprises two curvature portions, these two tangent settings of curvature portion make the S-shaped shape of this blade, and regardless of wind direction, described blade can both rotate towards one direction, without utilizing supplementary equipment to adjust the angle of this blade, have advantages of simple in structure, cost is low.
2. regardless of wind direction, described blade can both rotate towards one direction, has improved the blowing area of described blade, can obtain larger power stage.
3. while using, described blade vertical ground arranges, and the centroid position of described blade is nearer apart from ground, and the sky dress of described blade is highly lower, the installation of described blade, fixing simple.And in the time of need to increasing wind-power electricity generation power, the length that only need to increase this blade just can greatly increase its blowing area.
4. adopt described blade to generate electricity, utilize direct current generator to drive propeller to drive, regardless of wind direction, can both make sailing boat towards any direction, navigate by water at sea.
5. described in, blade can be used for street lamp to generate electricity, and is not subject to weather effect, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the schematic perspective view of a kind of blade for wind-power electricity generation of the utility model.
Fig. 2 has illustrated the schematic top plan view of a kind of blade for wind-power electricity generation shown in Fig. 1.
Embodiment
Please refer to Fig. 1 and Fig. 2, a kind of blade 100 for wind-power electricity generation of the present invention, S-shaped shape, comprises two curvature portions 10, these two tangent settings of curvature portion 10.
The sectional shape of this curvature portion 10 is preferably half-circle-arc shape, and certainly, the sectional shape of this curvature portion 10 can be also the curve form of rounding off.
This blade 100 is preferably one-body molded by metal or plastic materials.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
Claims (3)
