Description
Technical field
The utility model relates to the device that a kind of wind energy efficiently is converted into electric energy, belongs to the utilization of new energy resources field.This device passes through generator blade contour analysis and design, and the resisting moment that can hide the rotation of obstruction wind energy conversion system to without hindrance design, the diversion Design of this whole generator aerodynamic arrangement fully, realize that this wind energy conversion system non-resistance rotates, thereby improve wind energy transformation efficient greatly.The utility model existing in the market wind-driven generator relatively has higher wind energy utilization and wind-powered electricity generation conversion ratio.
Background technique
Energy shortage has at present become one of principal element of restriction China socio-economic development, and in China, except energy utilization rate is low, also there are a series of problems such as environmental pollution, ecological degeneration outward in energy waste phenomenon ubiquity.Wind energy has huge development potentiality as a kind of pollution-free, reproducible new energy, and in recent years, wind energy also comes into one's own day by day as a kind of new energy of high-efficiency cleaning.Rationally utilize wind energy, both can reduce environmental pollution, can alleviate increasing energy starved pressure again.Especially, global in recent years energy resources shortage, oil price hurricane rise and the Global Greenhouse Effect aggravation, impel various countries to step up to develop green energy resource, and wherein, wind-power electricity generation is one of big event of the development renewable sources of energy.The expert thinks that wind energy develops to " the strategy alternatives energy " direction from " replenishing the energy " at international energy field institute role.
Wind is tellurian a kind of natural phenomenon, is caused by solar radiant heat.Shine upon earth surface, the earth surface difference of being heated everywhere produces the temperature difference, thereby the convective motion that causes atmosphere forms wind.Have only about 2% to be converted into wind energy though arrive according to estimates in the solar energy of the earth, its total amount is still very considerable.The wind energy in the whole world is about 2.74 * 10
9MW, wherein available wind energy is 2 * 10
7MW is also bigger 10 times than the water energy total amount that can develop on the earth.
Wind energy has huge development potentiality as a kind of pollution-free, reproducible new energy, and in recent years, wind energy also comes into one's own day by day as a kind of new energy of high-efficiency cleaning.Rationally utilize wind energy, both can reduce environmental pollution, can alleviate increasing energy starved pressure again.
Without hindrance guide flowing type vertical axis wind generator described in the utility model mainly is made of blade, generator, axis, guide plate, empennage, base plate and main shaft.Concerning the vertical axis wind generator, the basic reason of rotation is: because the effect of wind-force, make on the power arm of pneumatic equipment blades made and the resistance arm and produced torque difference.The utility model adopts guide plate to eliminate the resistance of wind energy conversion system, strengthens power, has fundamentally solved the not high problem of wind energy conversion system efficient.The function of guide plate mainly is two, guide plate can cover the resistance arm of wind energy conversion system on the one hand, make resistance arm not produce resistance, on the other hand, guide plate should blow to the wind water conservancy diversion of resistance arm, make it to blow to power arm, and promptly adopting the guide plate after-blow is the sum total of motive force arm and resistance arm wind-force to the wind of power arm, therefore the wind speed that blows to power arm increases, and has correspondingly also produced bigger power.Therefore, under the double action that the resistance arm resistance disappears and power arm power increases, the rotating speed of this wind energy conversion system can improve greatly, transfers out more electric energy thereby drive generator to the external world.
In addition, through the retrieval of patent database, also do not find and the similar wind generator device of this patent.
Summary of the invention
The purpose of this utility model be develop a kind of in, under the low wind speed operating mode wind energy efficiently is converted into the wind generating unit of electric energy.
For overcome in the common wind energy conversion system, drawbacks such as low wind speed can't generate electricity down, inefficiency, the utility model has adopted two wind wheels to be arranged in juxtaposition, and adopts and add the guide plate resistance, incremental that disappears, make wind energy conversion system can in, hang down efficient power generation under the wind operating mode.The characteristics of the utility model maximum are exactly to adopt guide plate to eliminate the resistance of wind energy conversion system, strengthen power, have fundamentally solved the technical problem of shadow to the wind-force engine efficiency.The function of the guide plate that the utility model adopts mainly shows two aspects, guide plate can cover and hinder the resistance arm that wind energy conversion system rotates on the one hand, make resistance arm not produce resistance, on the other hand, guide plate should blow to the wind water conservancy diversion of resistance arm, make it to blow to power arm, and promptly adopting the guide plate after-blow is the sum total of motive force arm and resistance arm wind-force to the wind of power arm, therefore the wind speed that blows to power arm increases, and has correspondingly also produced bigger power.Therefore, under the double action that the resistance arm resistance disappears and power arm power increases, the rotating speed of this wind energy conversion system can improve greatly, transfers out more electric energy thereby drive generator to the external world.
The without hindrance guide flowing type vertical axis wind of the utility model generator mainly is made of blade 1, blade device for carrying a tripot 2, axis 3, small rod 4, generator 5, guide plate 6, big connecting rod 7, empennage 8, base plate (base) 9, main shaft 10.Wherein Fig. 1 is the wind wheel that blade and generator are formed, and in the utility model, wind wheel shown in Figure 1 has two-part, and the resistance part that its layout thought is two wind wheels is divided and linked to each other, and is convenient to hide resistance, general arrangement schematic such as Fig. 4 and Fig. 5.Fig. 2 is guide plate and empennage, and guide plate has two compositions, covers the resistance part of two wind wheels respectively.Empennage is arranged in the guide plate rear, and effect is to make the wind-driven generator can automatic wind facing.
The technical scheme in the invention for solving the technical problem is: adopt guide plate should blow to the power arm of the wind water conservancy diversion of wind energy conversion system resistance arm to wind energy conversion system, thus the purpose that realizes reducing resistance, strengthens power.Specific practice is, at first with two adjacent layouts of wind wheel, and make resistance arm all be in the inboard, guide plate is arranged in dead ahead at wind energy conversion system, the size of guide plate is for just sheltering from the resistance arm of wind energy conversion system fully, the effect water conservancy diversion that so just can make the wind process guide plate that should blow to the wind energy conversion system resistance arm is to the power arm of wind energy conversion system, thereby realization reduces resistance, increases dynamic action.In addition,, empennage just in time is on the symmetry axis of wind energy conversion system, so just can makes wind energy conversion system in the time of operation, can guarantee the wind-driven generator efficient operation according to the variation automatic wind facing of wind direction at guide plate dead astern installing empennage.
The beneficial effects of the utility model are, catch wind efficient height, can start generating under the gentle breeze state, also have higher wind-powered electricity generation conversion efficiency in addition, can use in the most of area of China.
