Abstract

Bionic vertical axis windmill, including wind-force machine base, impeller shaft, impeller pivoted arm, blade are based on the present invention relates to one kind, the blade afterbody installs winglet by winglet rotating shaft, for improving vertical axis windmill automatic performance and power output.The blade tail end is adjustable apart from h with the center of rotation of winglet.It is improved the invention reside in traditional NACA series aerofoil sections, common aerofoil profile is divided into two, comprising, blade and winglet, this blade and winglet has relatively independent parameter attribute.When wind is acted on to this wind energy conversion system, blade and winglet by air simultaneously, the rotation of winglet can increase the static torque of wind energy conversion system, and the lifting in automatic performance is brought to wind energy conversion system;At the same time, the power output that it can lift wind energy conversion system.

Description

Based on bionic vertical axis windmill
Technical field
It is especially a kind of to be based on bionic vertical axis windmill the present invention relates to a kind of vertical axis aerogenerator.
Background technology
As economic develops rapidly, the mankind rise year by year for the demand of the energy.And at present China mainly use according to Old be traditional fossil energy, and fossil energy utilizes brought environmental problem also increasingly severe, while fossil energy Constantly reducing.Therefore, the regenerative resource of cleaning then turns into the key that China develops in the future.
Wind energy is increasingly paid attention to as a kind of regenerative resource of cleaning by countries in the world, in the world many countries Development and utilization to wind energy takes incentive mechanism, to slow down the problem of environmental pollution of this country.In China, wind energy is China's energy A crucial ring in the strategy of source, the development of wind energy advantageously accounts for the problem of environmental pollution of China.The wind energy resources of China is very It is abundant, in the abundant wind energy resources that the provinces such as the Inner Mongol, Gansu and three provinces in the northeast of China are all present, its wind energy that can be developed Reserves are about 200,000,000 KW, and these regional landform are flat, traffic convenience, are conducive to large-scale development wind power plant.China is also early in upper Begin in individual century use wind energy, the Wind Power Generation Industry growth momentum of China is also especially powerful in recent years, and installed capacity has exceeded U.S. State.The wind-driven generator for being used at present is mainly divided into two kinds of horizontal axis wind-driven generator and vertical axis aerogenerator.In wind In electric field, wind energy conversion system is then the important device for converting wind energy into electric energy.Wind energy conversion system is broadly divided into trunnion axis and vertical-shaft wind Machine, compared to horizontal axis wind-driven generator, vertical axis aerogenerator is not required direction of flow, it is not necessary to any water conservancy diversion Device;Its simple structure, it is easily installed;Small-size vertical axis wind turbine applies also for many building areas, can effectively utilize Architectural wind energy, reduces the consumption of primary energy;Meanwhile, an advantage of its maximum is:With the cost of horizontal axis wind-driven generator Compare, the cost of vertical axis aerogenerator is generally relatively low.However, vertical axis aerogenerator does not have very good automatic Performance, while power output is relatively low.
For appeal vertical axis aerogenerator shortcoming, it is necessary to be improved wound to vertical shaft wind power generator structure Newly, section blade is improved, its aerofoil profile is made up of blade body and winglet.Blade and winglet are acted on and can effectively improved simultaneously The automatic performance and power output of vertical axis aerogenerator.
The content of the invention
The present invention is in order to solve above-mentioned existing shortcoming, there is provided one kind is based on bionic vertical axis windmill, from hanging down D-axis wind-driven generator structure is started with, it is considered to Modern air kinetic theory, using the blade for installing winglet additional, using afterbody winglet The aerodynamic effects of rotation improve vertical axis aerogenerator performance.
To achieve the above object, the technical scheme is that:One kind is based on bionic vertical axis windmill, including wind Power machine base, impeller shaft, impeller pivoted arm, blade, the blade afterbody install winglet by winglet rotating shaft, vertical for improving Axle wind energy conversion system automatic performance and power output.
The blade tail end is adjustable apart from h with the center of rotation of winglet.
The blade is fixedly connected by impeller pivoted arm with impeller shaft, and impeller shaft is arranged on wind-force machine base.
The beneficial effects of the invention are as follows:
It is improved the invention reside in traditional NACA series aerofoil sections, common aerofoil profile is divided into two, comprising, blade and winglet, This blade and winglet have relatively independent parameter attribute.When simultaneously wind is subject to air to this wind energy conversion system, blade and winglet Effect, the rotation of winglet can increase the static torque of wind energy conversion system, the lifting in automatic performance is brought to wind energy conversion system;With this Meanwhile, its power output that can lift wind energy conversion system.
It is of the invention on vertical axis windmill, it is ensured that vertical axis windmill simple structure, be easily installed maintenance Deng other advantages, while improving the deficiency of vertical axis windmill automatic performance again, the power output of wind energy conversion system is improve.
Brief description of the drawings
Fig. 1 is the stereogram based on bionic vertical axis windmill of the invention;
Fig. 2 is the top view based on bionic vertical axis windmill of the invention;
Fig. 3 is aerofoil profile partial view.
Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, it is of the invention based on bionic vertical axis windmill, including wind-force machine base 4, impeller Rotating shaft 5, impeller pivoted arm 6, winglet rotating shaft 3, blade 1 and winglet 2.Blade 1 is fixedly connected by impeller pivoted arm 6 with impeller shaft 5, Impeller shaft 5 is arranged on wind-force machine base 4.The afterbody of blade 1 installs winglet 2 by winglet rotating shaft 3, for improving vertical shaft wind Power machine automatic performance and power output.
As shown in figure 3, the tail end of blade 1 is adjustable apart from h with the center of rotation of winglet 2.
The present invention be improved as prototype with NACA0015 aerofoil profiles after blade(Its winglet parts length is the 1/ of total chord length 4 length).Traditional NACA series aerofoil sections are divided into two, aerofoil profile front end as blade body, aerofoil profile afterbody as winglet, again New-type aerofoil profile is assembled into, distance between the two can change, and suitable spacing is conducive to the increase of wind energy conversion system power output, spacing Excessive or too small, its static torque can reduce, poorer with respect to automatic performance.But, compared to traditional single blade Vertical axis aerogenerator, automatic performance still has larger lifting.
