Description
Technical field
The present invention relates to a kind of wind-driven generator, especially a kind of vertical axis aerogenerator, belong to vertical-shaft wind hair
Technical field of motors.
Background technology
In today that economy is developed rapidly, energy supply outstanding problem, there is great change in world energy sources structure, i.e.,
From transformation from fossil energy to the sustainable energy based on regenerative resource.Therefore, the regenerative resource of cleaning is increasingly
Favored by countries in the world.Compared with other energy, wind energy has the amount of accumulateing huge, can regenerate, widely distributed, without pollution
The advantages of make it that all there is stronger advantage in technology and cost, therefore as current optimal renewable and clean energy resource it
One.So wind-power electricity generation becomes the focus of today's society, its superiority is returned to be summarized as at 3 points:First, in financial cost side
Face, the expense for building wind power plant is much lower compared with the expense of thermal power plant of hydroelectric power plant or nuclear power station;Secondly, wind-power electricity generation
Operation cost does not have other any consumption and fuel cost in addition to general maintenance;Again, wind energy be it is a kind of clean it is clean can be again
The raw energy.Wind-power electricity generation both efficiently utilizes natural resources, and natural environment is protected again, also solves people from far-off regions and uses
Electric anxious scarce problem.Therefore, various countries are continued to increase for wind energy development and using the investment cost of project, and wind power industry is in
Reveal unprecedented growth momentum.
China also begins to use wind energy early in eighties of last century, and the Wind Power Generation Industry growth momentum of China is also especially strong in recent years
Strength, installed capacity has exceeded the U.S., takes its place in the front ranks of the world.The wind-driven generator for being used at present is mainly divided into horizontal axis wind turbine hair
Two kinds of motor and vertical axis aerogenerator.In wind power plant, wind energy conversion system is then the important device for converting wind energy into electric energy.Wind
Power machine is broadly divided into trunnion axis and vertical axis windmill, and compared to horizontal axis wind-driven generator, vertical axis aerogenerator is to coming
Stream direction does not require;Its simple structure, it is easily installed;Small-size vertical axis wind turbine applies also for many building areas, energy
It is enough effectively to utilize architectural wind energy, reduce the consumption of primary energy;Meanwhile, an advantage of its maximum is and horizontal axis wind generating
The cost of machine is compared, and the cost of vertical axis aerogenerator is generally relatively low.However, due to wind mill airfoil by front come the side of stream
To the inhomogeneities of airflow function, cause the automatic poor performance of vertical axis aerogenerator, at the same its power output also compared with
It is low.
For the shortcoming of appeal vertical axis aerogenerator, the present inventor is added water conservancy diversion transposition to be opened by horizontal-shaft wind turbine
Hair, innovation is improved to vertical axis aerogenerator airfoil fan, installs inducer additional in its blade inlet edge to strengthen air-flow work
Use the uniformity of blade surface.Installing inducer additional can effectively improve automatic performance and the output of vertical axis aerogenerator
Power.
The content of the invention
The present invention is in order to overcome the shortcoming existing for prior art, there is provided a kind of vertical axis windmill with inducer, from
Vane of vertical shaft wind-driven generator stress is started with, it is considered to Modern air kinetic theory, and inducer is installed additional using edge in front of the blade,
The aerodynamic characteristics of blade is improved using the flowing effect produced by inducer rotation, so as to improve vertical-shaft wind hair
Motor performance.
The technical scheme is that:A kind of vertical axis windmill with inducer, including blade, base, impeller shaft,
Impeller pivoted arm, the blade inlet edge installs inducer additional, and the sky of blade is improved using the flowing effect produced by inducer rotation
Aerodynamic characteristics, so as to improve vertical axis aerogenerator performance.
The inducer connects blade by inducer rotating shaft.
Between a diameter of 2/3rds maximum blade thickness and maximum blade thickness of the inducer, highly with blade etc.
It is high.
The relative distance of the blade and inducer can adjust.
The blade connects impeller shaft by impeller pivoted arm, and impeller shaft is arranged on base.
The beneficial effects of the invention are as follows:Novel vertical axis wind turbine of the invention, that is, ensure that vertical axis windmill
Simple structure, the advantages of safeguarding is easily installed, while improving the deficiency of vertical axis windmill automatic performance again, improve
The power output of wind energy conversion system.
Brief description of the drawings
Fig. 1 is the vertical axis windmill structural upright schematic diagram with inducer of the invention;
Fig. 2 is the vertical axis windmill structure schematic top plan view with inducer of the invention.
Specific embodiment
Blade after being improved as prototype with NACA0015 aerofoil profiles below(A diameter of 2/3rds blade of inducer is most
It is highly contour with blade greatly between thickness and maximum blade thickness)As a example by the present invention is described in more detail with reference to accompanying drawing:
Such as Fig. 1, shown in 2, a kind of vertical axis windmill with inducer, including blade 1, inducer 2, inducer rotating shaft 3, base
4th, impeller shaft 5, impeller pivoted arm 6.
The leading edge of blade 1 installs inducer 2 additional, rotates produced flowing effect using inducer 2 to improve the air of blade 1
Dynamic characteristics, so as to improve vertical axis aerogenerator performance.The inducer 2 connects blade 1 by inducer rotating shaft 3.Leaf
Piece 1 connects impeller shaft 5 by impeller pivoted arm 6, and impeller shaft 5 is arranged on base 4.
Vertical axis aerogenerator with inducer of the invention, the blade of its aerofoil profile is changed by traditional NACA series aerofoil sections
Enter to obtain, inducer is also by transforming with blade of the invention on aerodynamic performance on traditional wind-guiding wheel construction
Optimal combination is reached.The relative distance of blade 1 and inducer 2 can be adjusted, and suitable spacing is conducive to wind energy conversion system to export
The increase of power, spacing is excessive or too small, and its static torque can reduce, poorer with respect to automatic performance.But, phase
Than in traditional airfoil vertical axis aerogenerator, automatic performance still has larger lifting.
When wind is to this wind energy conversion system, because blade inlet edge with the addition of inducer so that the air flow shape on the surface of blade
Condition has a very large change.The rotation of inducer can increase the static torque of wind energy conversion system such that it is able to largely carry
Rise the power output of wind energy conversion system;At the same time the function of automatic acceleration is also brought to wind energy conversion system.
