Abstract
The utility model provides a blade for an impeller of a mini-type wind-driven generator. The blade is provided with a core bar and a housing, wherein a leaf root is arranged at one end of the core bar and is used for being connected with a hub of the impeller, the other end of the blade is fixed in the housing as a leaf vein, and the housing is used for sweeping wind. The blade takes the shape of an emulational leaf, so that the root of the blade is well-knit and has high strength, the leaf apex is light, and the wind sweeping area is large; and the installation of the blade enables the rotor diameter and the attack angle to be adjusted in a certain range, so as to meet the requirement of a wind farm in the installation position and achieve the purpose of higher generating efficiency.
Description
Technical field
The utility model relates to the blade that a kind of small-sized wind power generator impeller is used.
Background technique
Existing small generator mostly is integral structure greatly with blade, there is the mounting hole that is no less than two to be used for fixedlying connected at root of blade with wheel hub, the joint of the easy damaged blade root of this Placement, influence working life, the intensity of root of blade is also not enough, because the position of mounting hole is to change, so can not carry out the adjustment of the rotor diameter and the angle of attack as required, on the other hand, existing blade is because the leaf structure characteristics cause wind sweeping area little, and generating efficiency is low.
The model utility content
The blade that provides a kind of small-sized wind power generator impeller that can effectively improve generating efficiency to use is provided the purpose of this utility model.
The blade that this small-sized wind power generator impeller that the utility model provides is used has core bar and shell, and an end of core bar is a blade root, is used for being connected with the wheel hub of impeller, and the other end is fixed in the shell as vein, and shell is used to sweep wind.
Described shell is crooked backward to downwind near the part of blade tip end.Described core bar is made of aluminum, and shell is made by the macromolecule lightweight composite materials.Core bar carries out the transition to flat by the tubular shape in big footpath to the tubular shape of path again from the blade root to the blade tip.Core bar comprises a mobile jib and a reinforcing bar, reinforcing bar be enclosed within mobile jib near the end of blade root and with it close-fitting be integrated.
The blade that the utility model small-sized wind power generator impeller is used is owing to adopted core bar, make this blade form a kind of shape of imitative leaf, not only root of blade is solid has very high intensity, and blade tip is in light weight, wind sweeping area is big, and the mounting hole on the blade root can be determined its position as required, thereby can carry out the adjustment of the rotor diameter and the angle of attack within the specific limits, with the wind field requirement of suitable mounting point, thereby reach the purpose that improves generating efficiency.And the utility model corrosion protection is anti-aging, and interchangeability is good, and cost is low, can industrialized production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a blade schematic representation of the prior art.
Embodiment
The utlity model has core bar 1 and shell 2 as can be seen from Figure 1, shell 2 is used to sweep wind, and core bar 1 one ends are as blade root, and the other end is fixed in the shell 2 as vein.Core bar 1 adopts aluminium or alloy aluminum to make, and shell 2 is made by the macromolecule lightweight composite materials.Core bar 1 carries out the transition to flat by the tubular shape in big footpath to the tubular shape of path again from the blade root to the blade tip.Adopt a tubule as mobile jib 11 during manufacturing, an extra heavy pipe is as reinforcing bar 12, reinforcing bar 12 be enclosed within mobile jib 11 near the end of blade roots and with it close-fitting be integrated, make reinforcing bar 12 1 ends in shell 2 end outside shell 2, intensity with the reinforced blade root, it will be connected with wheel hub a end outside shell 2 as blade root, therefore be provided with mounting hole 3 above, the design attitude of mounting hole 3 can be determined as required, to guarantee the best angle of attack, the diameter of impeller is regulated in certain limit.Mobile jib 11 extends to the blade tip direction, carries out the transition to flat then, and to blade tip attenuation gradually, weight alleviates the profile that makes shell 2 gradually, is subjected to the maximum support of core bar 1 simultaneously by root, makes blade frangibility not under the big situation of wind, the working life of raising blade.Tip segment is crooked backward to downwind, so that impeller forms negative pressuren zone at the rear portion.
