Abstract
The utility model discloses a wind motor belonging to the wind generating device field and comprising a stator and a rotor that are positioned on the same axis; wherein, the rotor is covered on the stator, and the external cycle of the rotor is provided with a plurality of blades, and the bottoms of the blades are fixed on the rotor, and end parts of each blade are fixed on the round circle framework, and the ends and bottoms of each blade are twisted in the same direction, while the blade bottom is arranged in the axial direction. The utility model is characterized in that: the blades form the entity of relatively strong intensity and support with each other; and the partial stress can be dispersedly borne by the residual blades to make the blades as light as possible; and the blade bottom is of relatively smaller stress, while the gradually twisted blade ends are more likely to under stress and produce large torque to make the generator realize operation under the gentle breeze; in addition, the blades of relative densities and increased wind stress faces are conductive to generate electricity under the gentle breeze. Compared with the existing technologies, the utility model has the advantages of effective large wind stress faces and light blades and generating electricity under the gentle breeze, thus can be applied to the areas of relatively less wind resources.
Description
Technical field
The utility model relates to a kind of electricity generating device, particularly a kind of device that utilizes wind-power electricity generation.
Background technique
In the prior art, a kind of wind-driven generator is arranged, mainly comprises the stator and the rotor of coaxial setting, in to establish the stator of permanent magnet cylindrical, stator is fixed on the back shaft end, rotor comprises the main shaft that is provided with winding, and in stator, main shaft stretches out the outer end of stator impeller is installed main shaft through bearing fixing, impeller is made up of some blades, to end distortion in the same way gradually, for the control blade is in the upwind position, the other end relative with impeller is provided with the wind direction rudder to blade on the described stator from root.In when work, wind blows wheel rotation, impeller drives rotor rotation, is fixed between winding on the main shaft and the permanent magnet and produces cutting magnetic line movement, makes rotor produce electric current, and rotor current is drawn through carbon brush and guiding.Its deficiency is: because each blade only fixes at root and main shaft, need the intensity of each blade bigger, especially for larger-size blade, can cause the weight of blade own very big, therefore, the wind-driven generator of big blade, its blade number is fewer, and such blade can not rotate under the less situation of wind-force.
The model utility content
The purpose of this utility model provides a kind of wind-driven generator, makes its effective wind-receiving face big, and leaf weight is light, can generate electricity under gentle breeze.
The purpose of this utility model is achieved in that a kind of wind-driven generator, the stator and the rotor that comprise coaxial setting, rotor is sleeved on the stator, the rotor periphery is provided with some blades, the root and the rotor of described blade fix, the end of each blade all fixes with a ring framework, and each blade twists to the end in the same way from root, and root of blade is axial setting.
The utility model is by the setting of annular frame, make between each blade and not only be connected as a single entity at root of blade, and also be connected as a single entity at blade tip, root of blade is axial setting, makes each blade constitute the bigger entity of intensity, and blade plays a supportive role mutually, local pressure can be disperseed to bear by rest blade, like this, under equality strength, blade can be done light closely possibly; When blade was closeer relatively, its intensity was better; Root of blade is axial setting, can make root of blade stressed less, root of blade twists gradually to blade tip, make blade tip easier to be stressed, the moment of torsion of the stressed generation of blade tip is big, makes generator can realize motion under gentle breeze, in addition, the increase of lobe numbers can increase wind-receiving face, helps generating electricity under gentle breeze.Compared with prior art, effective wind-receiving face of the present utility model is big, and leaf weight is light, can generate electricity under gentle breeze, can use relative less area with wind resource.
Be to reduce the use of carbon brush, described rotor is hollow barrel-type, and stator comprises main shaft and the winding on the main shaft, main shaft warp and Bearing Installation are in rotor, main shaft one end stretches out outside the rotor and back shaft fixes, and is fixed with permanent magnet in the rotor internal cavity, leaves the gap between permanent magnet and the winding.The direct like this guiding of drawing from stator can reduce the use of carbon brush, has increased the reliability of device.
For making device stability good, described rotor is hollow barrel-type, stator comprises main shaft and the winding on the main shaft, main shaft warp and Bearing Installation are in rotor, the main shaft two ends are stretched out rotor and are also fixed with two back shafts respectively outward, be fixed with permanent magnet in the rotor internal cavity, leave the gap between permanent magnet and the winding.This technological scheme makes the rotating shaft two ends that support all be arranged, thereby makes device more reliable and more stable.
