Description

Vertical axis wind turbine
The present invention relates to a kind of large-scale wind turbine, it can be for various purposes, comprise that generating provides power.
Wind turbine can be divided into two classes substantially, i.e. vertical shaft turbine and horizontal axis turbine.The vertical shaft turbine has the advantage more exclusive than horizontal axis turbine.At first, the vertical shaft turbine can in any direction receive wind-force, and needn't redirect to the direction of wind, and this then is necessary for the horizontal axis turbine.This just means the direction that does not need complicated layout to keep turbine is correctly aimed at wind.
Another major advantage of vertical axis wind turbine is: the size of turbine is big more, then easy more structure, because blade is big more from the radius of turbine, the rotation of turbine will be slow more under any wind speed.Therefore for the large-scale vertical wind turbine, the centrifugal force problem that is produced by the turbine rotation is just not too outstanding.This and horizontal axis turbine antithesis, the specification of its structure is less, centrifugal force is just big and keep blade with higher tension force, it is crooked therefore to trend towards making blade to produce.Yet for large-scale horizontal axis turbine, less centrifugal force can cause serious mechanical constraint, for example those constraints that brought by bending blade stress, and when the size of horizontal axis turbine increased, this constraint also increased significantly.
The large-scale vertical wind turbine generally adopts airfoil fan, and they are separated equably around a supporting tower, and the main axis of supporting tower is in Vertical direction.
Learn that also can construct a kind of vertical shaft turbine, wherein the wing chord of blade forms the shape with a Troposkein curve, make that act on centrifugal force on the blade is tension force but not bending force.But the shortcoming that adopts this curve shape is that the major part of blade is in leeward angle, thereby can only catch the part wind energy.Therefore obviously, an effective more airfoil fan can bring enlarging markedly of efficient.
In design large-scale vertical wind turbine, can utilize a higher relatively aspect ratio, promptly chord is with respect to the ratio of wing chord.Only when the physical length of blade when scanning diameter with respect to it, just can obtain this aspect ratio preferably, and this need adopt the tractive wirerope to wait to reinforce this structure.Owing to when turbine work, produce mechanical force, therefore need carefully be designed for especially the device of reinforcing this structure, and this normally adopt the tractive wirerope to wait to reinforce this structure, these tractive wireropes to be positioned at simultaneously under the blade of rotation and on.
A shortcoming of known vertical axis wind turbine is to be difficult to support suitably the wind turbine structure.Though can construct a static supporting tower, it does not need tractive wirerope etc., aspect ratio is big more, supporting is just difficult more, because the physical size of blade and the load that acts on the turbine increase, therefore in the vertical shaft turbine of existing form, generally less adopt higher aspect ratio.When structure has a large-scale vertical wind turbine of higher aspect ratio, just produce problem, and supported the problem of turbine especially suitably, this supporting must stand the suitable power owing to turbine rotates and the wind-force impact produces.For this reason, general be connected with the tractive wirerope or be the pole of rigidity sometimes to structure in each position, with simultaneously under the blade of rotation with on support turbine suitably.Satisfied fixing in order to obtain, need to adopt a unpractical high center system, between the top of airfoil fan and tractive wirerope, to provide suitable gap.Except because of using tractive wirerope etc. to need the space, another shortcoming is that the tractive wirerope may interfere with wind flow.Also shortcoming when using the tractive wirerope is, if center support structure with blade rotation, then acting on structural tension force by the tractive wirerope can increase extra load to bearing.
The claimant thinks that for obtaining maximum efficient and power, the airfoil fan of vertical shaft turbine should be straight substantially, and its longitudinal axis should approximate vertical.For large-scale power generation arrangement, the turbine of minimum dimension should have two, three vertical vanes preferably at least, and blade is equidistant from the supporting tower, and blade has and preferably equals the length of blade from least 1.5 times of the radial distances of tower structure.
