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, as renewable eco-friendly power source, is more and more subject to the attention of countries in the world.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, than also large 10 times of the water energy total amounts that can develop on the earth.Wind Energy In China available potential greatly, distribute widely, only the wind energy content of land is just had an appointment 2.53 hundred million kilowatts; Along with the 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 between 2006 to 2007, Global Wind-energy capacity of installed generator expands 27%.Existing 90,000 megawatts in 2007, in future 20-25, 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 main flow types such as horizontal axis wind-driven generator, vertical axis aerogenerator, Da Dalieshi wind wheel.When wind-force reaches incision wind speed, wind blows fan main body blade rotary, when fan main body rotation, drive disk generator rotor to rotate the permanent magnetic field on blower fan stator is done to cutting magnetic induction line motion, according to electromagnetic induction principle, in rotor wire, produce alternating current.When the charging voltage and current that the electric current and voltage of generator reaches storage battery requires, the alternating current that wind-driven generator produces is stable to charge in batteries after rectification.Electric energy in storage battery can or do interchange electricity consumption for direct current after inverter inversion.When the voltage and current that reaches cut-out wind speed, generator when wind-force exceeds the charging requirement of storage battery or storage battery and is full of, control circuit disconnects charging current automatically, forms off-load, and 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, incision wind speed is 3m/S, and when wind speed is less than 2m, blower fan does not generate electricity, and while being or gentle breeze less at wind speed, can not generate electricity.2, horizontal axis wind-driven generator has selection to wind direction, needs constantly to adjust wind direction in power generation process, to reach the best some effect of sending out, is difficult to utilize different wind directions to obtain best generating effect.3, each wind wheel only drives the conversion efficiency of a disk generator wind energy low.4, when blower fan turns round, between parts, friction is large, and the generator life-span is short, often needs to change, and increases maintenance and maintenance cost.5, when wind speed changes, generator speed changes comparatively fast, and torque ripple is larger.6, use is highly higher, and inconvenience is installed, and floor space is larger.7, 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 in prior art, wind-driven generator exists, providing in a kind of situation of low wind speed can normal power generation, the magnetic suspending wind turbine generator that wind-powered electricity generation conversion efficiency is high, be easy to regulate 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, described fixed support is provided with stent magnet, in described stent magnet, be provided with back shaft, described back shaft periphery is provided with rotating wind wheel, described rotating wind wheel is provided with wind wheel blade, and described rotating wind wheel below is provided with and described stent magnet homopolarity wind wheel magnet in opposite directions, between described rotating wind wheel and back shaft, is provided with disk generator.
Further, described back shaft top is provided with lightning arrester.
Further, described lightning arrester is pin type lightning arrester.
Further, described rotating wind wheel is provided with wind wheel framework blade.
Further, described disk generator is 1 to 10.
Further, described disk generator is 2.
Further, described wind wheel blade is 2 to 20.
Further, described wind wheel blade is 13.
Further, between described back shaft and rotating wind wheel, be provided with the screw thread that matches, rotating wind wheel rotates upwards along back shaft, regulates rotating wind wheel height.
Useful technique effect of the present invention is: in the time carrying out wind-power electricity generation, be that 1m/S can generate electricity by starter-generator 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 at any time best power point, structurally improve to some extent compared with horizontal axis wind-driven generator.Each wind wheel only drives the conversion efficiency of a disk generator wind energy low compared with the present invention.When blower fan running, between parts, rub little, prior art relatively, generator life 4 years or longer.When wind speed changes, blower fan protection framework can stable generator rotating speed, and torque ripple is less.Floor space of the present invention is little, and using area is flexible.Blower fan means of fixation of the present invention is flexible, only needs screw fixing.Minimum setting height(from bottom) is 2m, cost-saving, more has practical value.The present invention is a kind of novel small-power magnetic suspension vertical shaft wind-driven generator.On the basis of traditional wind, do rational technological improvement, the conversion efficiency of wind energy has been improved more than 50%.Can greatly reduce the cost of electricity-generating of wind-driven generator.Utilize magnetic levitation technology to reduce the frictional force between parts when fan operation, and then extend the life-span of wind-driven generator, by the screw thread on rotating wind wheel and back shaft, highly regulate simple and easy to doly, there is unobviousness.
