Description
Technical field
The present invention relates to a kind of wind-driven generator, particularly a kind of wind-driven generator that outside blade, is provided with flexible rings.
Background technique
At present, the use of middle-size and small-size wind-driven generator more and more widely, as street lamp, remote districts etc.; In use, people can expect problems such as safety, efficient usually; At present, employed wind-driven generator comprises body and blade, this structure, and blade is in rotary course, and blade is subjected to action of centrifugal force might fly away from body, so just may cause the generation of safety problem, and in addition, the wind energy major part is scattered and disappeared from blade tip; For addressing these problems, on some small-sized wind power generator blade, be provided with steel ring now, can keep energy to be difficult for scattering and disappearing like this from blade tip, and can make blade be difficult for flying out, but because therefore the structure and the weight of steel ring, are difficult to realize on medium-sized wind-driven generator, and it carries inconvenience, installs also inconvenient.
Summary of the invention
The objective of the invention is to adopt structure of the present invention, can use on middle-size and small-size wind-driven generator, and can increase work efficiency, control the rotating speed of blade preferably for a kind of flexible outer ring type wind power generator is provided, easy to carry, easy for installation.
For achieving the above object, flexible outer ring type wind power generator of the present invention comprises body and wind wheel; Described wind wheel comprises wheel hub, blade and is located at flexible rings on the blade outer end; Described blade is located on the wheel hub uniformly; Be provided with the connection set of the five equilibrium flexible rings that equates with blade sheet number between described flexible rings and the blade; Blade and flexible rings are connected as a single entity by connection set, are provided with deceleration blade outside described flexible rings, and described deceleration blade is articulated on the flexible rings, and pivoting point is divided into deceleration blade two sections of asymmetric weight; Described deceleration blade two is provided with elastic component, and described elastic component is connected with flexible rings.
Adopt this structure, owing to be provided with flexible rings outside blade, like this, energy just is difficult for running off from blade tip, and forms eddy flow easily in flexible rings, therefore, has improved the working efficiency of wind-driven generator; Because flexible rings and blade have been linked as one, like this, under the effect of flexible rings, blade is owing to centrifugal force causes security incident with regard to being difficult for flying away from body again; Owing to be flexible rings, can fold, so it is easy to carry; When mounted, earlier with blade installation to body, not fastening, then flexible rings is installed on the blade by connection set, at last that blade and body is fastening, adopt such installation procedure,, so just can guarantee the blade installation uniformity of back on whole machine body well on flexible rings because connection set is evenly to distribute, stationarity is better in the running to make motor, install also more conveniently, can not only use small-sized wind power generator like this, and can use on the medium-sized wind-driven generator; Outside the corresponding flexible rings of blade, deceleration blade is set, described deceleration blade is articulated on the flexible rings, pivoting point is divided into deceleration blade two sections of asymmetric weight, when the rotation of blade of wind-driven generator reaches certain speed, because action of centrifugal force makes the heavy end of deceleration blade outwards move around pivoting point, form a barge board, thereby play the effect of speed limit, when rotating speed within the specific limits the time, then deceleration blade does not move; Elastic component is set, when wind speed round within the specific limits the time, because the effect of flexible two elastic component, any motion does not take place in spring sheet, and when the wind wheel rotational speed reached certain speed, the centrifugal force that is produced was greater than the elastic force of elastic component, at this moment, the heavily end of spring sheet outwards moves, and forms barge board, thus the rotating speed of restriction wind wheel.
As improvement, described flexible rings surface scribbles coating.Coated on flexible rings can improve its surface finishment, reduces the resistance to motion of wind wheel.
Specialize as of the present invention, described connection set is a buckle.The employing buckle connects, installation, convenient disassembly.
Specialize as of the present invention, described connection set is a screw.Adopt screw and connecting sheet, be connected firmly, reliably.
Specialize as of the present invention, described connection set is the buckle of connecting sheet, band groove and is located at groove fixed body on the flexible rings, and the buckle of described connecting sheet and band groove is connected as a single entity, and described connecting sheet is connected with blade.Adopt this structure, easy for installation.
As improvement, on flexible rings, be provided with balancing weight.Adopt this structure, wind wheel can carry out autobalance to wind wheel by balancing weight when rotated.
Specialize as of the present invention, described blade quantity is five.Blade is set to five, after flexible rings is installed on the blade, then can make flexible rings become an approximate circle.
Compared with prior art, the present invention is owing to be provided with flexible rings on blade tip, and therefore, energy just is difficult for scattering and disappearing from blade tip, and can form eddy flow in flexible rings, helps increasing work efficiency; Owing to be flexible rings, it is light and can fold, and is easy to carry like this, easy for installation, and can be used on the middle-size and small-size wind-driven generator; Owing to outside flexible rings, be provided with deceleration blade and elastic component, so just can control automatically the blade rotational speed preferably.
