Description
Technical field
The present invention relates to a kind of wind-driven generator that is used under the changeable environment of wind-force such as city, particularly is a kind of helical blade wind-driven generator.
Background technique
Traditional wind comprises generator (1), and the input shaft (4) of this generator (1) is gone up the wind blade that two or three strips are installed, and wind blade drives described generator under wind-drive transmission shaft rotates, thus generating.But this traditional wind blade can only utilize the wind of single direction to cut, and changeable wind direction and the wind speed in incompatibility city, especially in built-up city, because the influence of building, wind direction around the building is changeable, cut from wind from all directions, tend to cause the wind blade torsional deformation.Traditional wind wind-force blade rotational speed under high wind is higher, not only easily personnel and birds is damaged, and can bring bigger noise, disturbs normal work of people and rest.And the wind blade of wind-driven generator is bulky, and poor stability is very high to the stability requirement of base, especially in the urban area, is traditional leafy wind-driven generator can not to be installed on the roof.
The remarkable shortcoming of prior art is: under the changeable environment of wind direction and wind speed, wind blade can only utilize the wind of single direction to cut, and easy torsional deformation, and dangerous, noise is big, can not be installed in densely inhabited districts such as city.
Summary of the invention
The purpose of this invention is to provide a kind of helical blade wind-driven generator, the wind blade of this device can be accepted the wind of all directions and cut, and not yielding, work safety, little, the no potential safety hazard of noise, can be installed in densely inhabited districts such as city.
For achieving the above object, the invention provides a kind of helical blade wind-driven generator, comprise generator, on the input shaft of this generator wind blade is installed, its key is: described wind blade is a helical blade, the cross section of this helical blade is a serpentine, and described input shaft passes the mid point of this serpentine cross section.
The mid point of all serpentine cross sections of this wind blade is all on described input shaft.
If the preparation process of a serpentine helical blade is too complicated, wind blade can be made into two groove shape wind blades: the bilateral symmetry of described input shaft is equipped with a slice wind blade, and groove is recessed on the contrary, and promptly the cross section of these two wind blades is combined into serpentine; Described two groove shape wind blades are that the center is reversed clockwise or counterclockwise with the input shaft, constitute double-spiral structure.
Described wind blade drives described generator under wind-drive transmission shaft rotates, and generator obtains the kinetic energy generating.
Described generator is fixed on the locating support, bearing also is installed on this locating support connects described input shaft.
Locating support had both been fixed generator, again input shaft was carried out spacingly, and when wind blade drove input shaft and rotates, locating support had guaranteed that input shaft can stablize rotation.
Described input shaft vertically is installed on the described generator, or level is installed on the described generator.
If main airstream is too high apart from ground or roof, can adopt the mode of vertical installation, vertically the mode floor space of installing is less; The center of gravity of horizontal mounting type is low, and stability better can increase the length of input shaft and wind blade under this mode, even the mode that adopts the more piece wind blade to assemble successively.
Described wind blade is provided with at least one serpentine stiffening rib, and described input shaft passes the mid point of this serpentine stiffening rib.
Many serpentine stiffening ribs are set, equate at interval between each serpentine stiffening rib.
Plane, described serpentine stiffening rib place is vertical with described input shaft.
The serpentine stiffening rib has improved the rigidity of wind blade, avoids causing because wind-force is excessive described wind blade torsional deformation, even damages.
Described input shaft also is fixed with the rectangle shakeless deckle, and described wind blade is positioned at this rectangle shakeless deckle.
Fixedly connected with first group of opposite side of described rectangle shakeless deckle in described wind blade two ends, second group of opposite side of this rectangle shakeless deckle is parallel with described input shaft.
Two angles of one end of described wind blade are fixed on corresponding in first group of opposite side of the described rectangle shakeless deckle limit; Two angles of the other end of described wind blade are fixed on another corresponding in first group of opposite side of described rectangle shakeless deckle limit, like this, and further firm described wind blade.
Second group of opposite side of described rectangle shakeless deckle increased the rotary inertia of described wind blade, strengthened the stability that this wind blade rotates.
Helical blade wind-driven generator provided by the invention, no matter how many angles on described input shaft and ground is, described wind blade all can reach good stressed rotating effect, wherein, if described input shaft and wind blade are shorter, input shaft vertically is installed on the described generator, its best results, at this moment, no matter what kind of wind direction is, the sense of rotation of described wind blade is constant all the time; According to aerodynamic principle as can be known, the rotating speed of described wind blade has the restriction of maximum (top) speed, can not damage owing to rotating speed is too high, does not also have very high noise; In addition, because gyroscopic effect, when described input shaft was consistent with gravitational direction, rotating speed was high more just steady more.
When described input shaft level was installed on the described generator, the wind-force that described wind blade also can be accepted most of direction rotated.
Helical blade wind-driven generator provided by the invention can also couple together a plurality of wind blades by the mode of connecting shaft, drives more powerful generator.At this moment, mode the best that adopts the input shaft level to install.
Remarkable result of the present invention is: the wind that can accept all directions is cut, and not yielding, work safety, little, the no potential safety hazard of noise, can be installed in densely inhabited districts such as city.
