Description
Technical field
The utility model relates to a kind of wind-driven generator, in particular, relates to a kind of small-sized a kind of magnetic suspending wind turbine generator.
Background technique
Current, wind energy power more and more is subject to 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, than also large 10 times of the water energy total amounts that can develop on the earth.The Wind Energy In China available potential is very big, distribution is wide, and 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, the Global Wind-energy capacity of installed generator enlarges 27%.Existing 90,000 megawatts in 2007, in the 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 the incision wind speed, wind blows fan main body blade rotary, drive the rotation of disk generator rotor during the fan main body rotation permanent magnetic field on the blower fan stator is done the cutting magnetic induction line motion, according to electromagnetic induction principle, produce alternating current in the rotor wire.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.Electric energy in the storage battery can or be done the interchange electricity consumption for direct current after the inverter inversion.When the voltage and current that reaches cut-out wind speed, generator when wind-force exceeded the charging requirement of storage battery or storage battery and is full of, control circuit automatic disconnection charging current formed off-load, and the protection storage battery forms simultaneously damping 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, can not generate electricity when namely being or gentle breeze less at wind speed.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, only to drive the conversion efficiency of a disk generator wind energy low for each wind wheel.Rub between the parts when 4, blower fan turns round large, the generator life-span is short, often needs to change, and increases maintenance and maintenance cost.Generator speed changed comparatively fast when 5, wind speed changed, and torque ripple is larger.6, use is highly higher, and inconvenience is installed, and floor space is larger.7, the blower fan means of fixation is dumb.
Summary of the invention
Technical purpose of the present utility model is to overcome the above-mentioned technical problem that wind-driven generator exists in the prior art, providing in 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, the technical solution of the utility model is:
Magnetic suspending wind turbine generator, include fixed support, described fixed support is provided with stent magnet, be provided with back shaft in the described stent magnet, 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, is provided with disk generator between described rotating wind wheel and the back shaft.
Further, be provided with lightning arrester above the described back shaft.
Further, described lightning arrester is the 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, be provided with the screw thread that is complementary between described 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 utility model 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 at any time the best power point, 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 utility model.Rub little relative prior art, generator life 4 years or longer during the blower fan running between the parts.But blower fan protection framework stable generator rotating speed when wind speed changes, torque ripple is less.The utility model floor space is little, and using area is flexible.Blower fan means of fixation of the present utility model is flexible, only needs screw to fix and gets final product.Minimum setting height(from bottom) is 2m, saves cost, more has practical value.The utility model is a kind of novel small-power magnetic suspension vertical shaft wind-driven generator.Done rational technological improvement on the basis of traditional wind, improved the conversion efficiency of wind energy more than 50%.Can greatly reduce the cost of electricity-generating of wind-driven generator.Frictional force when utilizing magnetic levitation technology to reduce fan operation between the parts, and then prolong life-span of wind-driven generator by the screw thread on rotating wind wheel and the back shaft, is highly regulated simple and easy to doly, has unobviousness.
