Description
Technical field
The present invention relates to a kind of wind-driven generator, in particular, relate to a kind of small-sized a kind of magnetic suspending wind turbine generator.
Background technique
Current, wind energy power more and more receives the attention of countries in the world as renewable eco-friendly power source.Having a high potential of wind energy power, the wind energy in the whole world is about 2.74 * 109MW, and wherein available wind energy is 2 * 107MW, and is also bigger 10 times than the water ability total amount that can develop on the earth.China's wind energy capable of using enormously potential, distribute widely, only the wind energy content of land is just had an appointment 2.53 hundred million kilowatts; Along with development of global economy, wind energy market also develops rapidly.Since two thousand four, global wind-power electricity generation ability has been turned over some, and in the period of 2006 to 2007, global wind energy power electric motor power enlarges 27%.Existing 90,000 megawatts in 2007 estimate in the following 20-25 that wind energy market, the world will increase progressively 25% every year.
Wind-driven generator is a kind of device of realizing the conversion of wind energy electric energy, mainly contains several kinds of main flow types such as horizontal axis wind-driven generator, vertical axis aerogenerator, Da Dalieshi wind wheel.When wind-force reaches the incision wind speed; The rotation of wind blows blower fan main body blade; Drive the disk generator rotor rotation during rotation of blower fan main body the permanent magnetic field on the blower fan stator is done the cutting magnetic induction line motion,, produce alternating current in the rotor wire according to electromagnetic induction principle.When the charging voltage and current that the electric current and voltage of generator reaches storage battery required, the alternating current that wind-driven generator produces was stable to charge in batteries after rectification.Electricity of accumulator can supply direct current or after the inverter inversion, do the interchange electricity consumption.When charging requirement or the storage battery that the voltage and current that reaches cut-out wind speed, generator when wind-force exceeds storage battery was full of, control circuit automatic disconnection charging current formed off-load, and the protection storage battery forms damping simultaneously and reduces wind-driven generator rotating speed protection generator.
Wind-driven generator of the prior art has following shortcoming: 1, the incision wind speed is 3m/S, wind speed during less than 2m blower fan do not generate electricity, promptly be can not generate electricity during less or gentle breeze at wind speed.2, horizontal axis wind-driven generator has selection to wind direction, in power generation process, needs constantly adjustment wind direction, to reach the best some effect of sending out, is difficult to utilize different wind directions to obtain best generating effect.3, only to drive the conversion efficiency of a disk generator wind energy low for each wind wheel.It is big to rub between the parts when 4, blower fan turns round, and the generator life-span is short, often needs to change increase maintenance and maintenance cost.Generator speed changed comparatively fast when 5, wind speed changed, and torque ripple is bigger.6, use is highly higher, and inconvenience is installed, and floor space is bigger.7, the blower fan means of fixation is dumb.
Summary of the invention
Technical purpose of the present invention is to overcome the above-mentioned technical problem that wind-driven generator exists in the existing technology; Providing under a kind of situation of low wind speed can normal power generation, the magnetic suspending wind turbine generator that the wind-powered electricity generation conversion efficiency is high, be easy to regulate the rotating wind wheel height and be easy to dismounting and change.
For realizing above technical purpose, technological scheme of the present invention is:
Magnetic suspending wind turbine generator; Include fixed support, said fixed support is provided with stent magnet, is provided with back shaft in the said stent magnet; Said back shaft periphery is provided with rotating wind wheel; Said rotating wind wheel is provided with wind wheel blade, and said rotating wind wheel below is provided with and said stent magnet homopolarity wind wheel magnet in opposite directions, is provided with disk generator between said rotating wind wheel and the back shaft.
Further, said back shaft top is provided with lightning arrester.
Further, said lightning arrester is the pin type lightning arrester.
Further, said rotating wind wheel is provided with wind wheel framework blade.
Further, said disk generator is 1 to 10.
Further, said disk generator is 2.
Further, said wind wheel blade is 2 to 20.
Further, said wind wheel blade is 13.
Further, being provided with the screw thread that is complementary between said back shaft and the rotating wind wheel, rotating wind wheel along the back shaft rotation is upwards regulated the rotating wind wheel height.
Useful technique effect of the present invention is: when carrying out wind-power electricity generation, be that 1m/S can the starter-generator generating to the requirement of wind speed, solved the bottleneck of the low wind speed restriction of wind-driven generator.Do not need wind direction to select, can reach the best power point at any time, structurally improve to some extent than horizontal axis wind-driven generator.The conversion efficiency that each wind wheel only drives a disk generator wind energy is low than the present invention.It is little to rub between the parts during blower fan running, relative existing technology, and the generator life-span prolongs 4 years or longer.But blower fan protection framework stable generator rotating speed when wind speed changes, torque ripple is less.Floor space of the present invention is little, uses the place flexible.Blower fan means of fixation of the present invention is flexible, only needs screw to fix and gets final product.Minimum setting height(from bottom) is 2m, practices thrift cost, has more use value.The present invention is a kind of novel small-power magnetic suspension vertical shaft wind-driven generator.On the basis of traditional wind, done rational technological improvement, improved the conversion efficiency of wind energy more than 50%.Can reduce the cost of electricity-generating of wind-driven generator greatly.Frictional force when utilizing magnetic levitation technology to reduce fan operation between the parts, and then prolong life-span of wind-driven generator through the screw thread on rotating wind wheel and the back shaft, is highly regulated simple and easy to doly, has unobviousness.
