Description

Magnetic suspending wind turbine generator

One, technical field

The utility model relates to a kind of generating equipment, particularly a kind of magnetic suspending wind turbine generator.

Two, background technology

Along with economy fast development, the electric energy shortage has become worldwide problem, in China, the outlying mountain area of mains supply difficulty particularly, life electric consumption on lighting all can't resolve, and the economy of this and develop rapidly has formed distinct contrast with science and technology, for this reason, the development and utilization of wind energy is paid attention to by people, and the exploitation of wind-driven generator provides convenience to a certain degree with using to people's daily life electricity consumption.But mostly the wind-driven generator that uses is to be made of rotor stator at present, and rotor places in the stator, i.e. the inner-rotor-type wind-driven generator, rotor drives the running generating through wind wheel during use, because its structural problem, particularly the wind wheel rotating torque is little, the motor radiating weak effect, energy consumption is big, therefore, wind energy utilization is low, the generating weak effect, and can only work under high speed winds, power-on time and amount of power supply do not satisfy the actual needs in the daily life far away.Though existing have a kind of magnetic suspension permanent magnet wind-driven generator (application number is 99243654.0), because its complex structure, and be inner rotor core, the wind wheel rotating torque is little, and it uses and is unsatisfactory.

Three, utility model content

Actual needs at above-mentioned situation and electricity consumption, the utility model provides a kind of new magnetic suspending wind turbine generator, can make full use of wind energy to separate the high efficiency generating problem of wind-driven generator, the technical scheme of its solution is, the dress permanent magnet constitutes the shell type rotor in the housing, the permanent magnet inner face is the gap stator is housed, the stator winding coil is arranged on the stator, stator and stator winding coil are contained on the fixed axis, the fixed axis upper and lower side is equipped with toroidal magnet (magnetic pole) near the housing place, with magnet (magnetic pole) be housed on the housing of toroidal magnet corresponding position form magnetic suspension structure (device), fixed axis passes housing and places up and down in the end cap, the utility model novel structure uniqueness, wind wheel is contained on the wind-driven generator shell, the wind wheel rotating torque is big, coherence is big, and, owing to adopt magnetic suspension structure, effectively overcome the friction that is produced between former rotating shaft and bearing, reduced mechanical wear, being beneficial to very much wind wheel rotates, just can use generating under the low speed wind power, match, can realize round-the-clock power supply with electrical storage device, satisfy the needs of powering in people's daily life greatly, be the more wide bright prospect of development and utilization developing of wind energy.

Fig. 1 is a structural profile front view of the present utility model.

Fig. 2 is an inner-rotor-type structural profile front view of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

By shown in Figure 1, its structure of the utility model is, permanent magnet 8 is housed in the housing 7 constitutes the shell type rotor, permanent magnet 8 inner faces are the gap stator 9 are housed, and coil winding 11 is arranged on the stator 9, and stator 9 is contained on the fixed axis 2 with coil winding 11, fixed axis 2 upper and lower sides are equipped with toroidal magnet 3 near the housing place, with on the housing of toroidal magnet 3 corresponding positions magnet 4 is housed, form magnetic suspension structure (device), fixed axis 2 passes housing and places in upper end cover 1 and the bottom end cover 14; In order to guarantee result of use and whole sturdy and durable, housing about in the of 7 end cap be fastened on the housing 7 by bolt 5 and nut 6; Cutting 10 is arranged on the fixed axis 2, and the current feed 12 of stator coil winding 11 places in the cutting 10, and electric current is drawn; Pushing tow magnet 15 is equipped with in fixed axis 2 lower ends, be equipped with on the bottom end cover 14 of pushing tow magnet 15 corresponding positions with fixed axis 2 on the pushing tow magnet 16 (also can be winding coil) of pushing tow magnet 15 same polarities; Magnet 4 can adopt trapezoidal magnet, and upper end cover 1 place is gapped 13, is beneficial to that magnetic suspension is regulated, heat radiation.

It is to be noted especially; the utility model also can be suitable for inner-rotor-type; as shown in Figure 2; only residing locational different with the external-rotor-type difference at rotor and stator; current feed form difference; therefore, the total design of inner and outer rotors formula and external-rotor-type comes down to the same, all is protection ranges of the present utility model.

Coil winding 11 adopts prior aries or is 99243654.0 technology with reference to application number, also can be according to actual needs more separately coiling all can.During use, wind wheel is contained on the housing or on the cover body, drives the rotor rotation generating.

By said structure as can be seen, the utility model has changed the version of existing wind-driven generator, wind wheel is loaded on the housing, housing can be a generator casing, it also can be the generator outer cover, or the combination of outer cover and shell, if inner-rotor-type, wind wheel can be contained on the outer cover, drive internal rotor again and rotate generating, owing on transmission device, adopted magnetic drives and shell rotating manner, overcome the big defective of traditional wind tripping force, because magnetic driving mechanism is with the principle design of magnetic repulsion, therefore, be not contact friction between each magnetic drive device, thereby also just overcome between the conventional transmission device because the increase of friction the motive consumption that is brought; Between alternator shaft and end cap, remove metal bearing in the past and adopted magnetic levitation system, this structure on the one hand, in the purpose that has played the transmission that reduces greatly to rub aspect the power transmission of magnetic suspension permanent magnet wind-driven generator, on the other hand, also overcome substantially because the deadweight of generator self rotor and rotating shaft, the consumption of the actuating force of bringing, overcome the soft partially shortcoming of p-m rotor wind-driven generator load characteristic, particularly adopt the external rotor form, changed the structure of traditional wind, housing can be the wind-driven generator shell, it also can be the generator outer cover, during use, wind wheel, casing constitutes the rotor of external-rotor-type wind-driven generator together with wind wheel leaf and shell inner magnet, fixedly vertical shaft and stator winding constitute stator, wind wheel is the power wheel of wind-driven generator, it is again the part of generator amature, novel structure and uniqueness, because it is constant that maintenance supports fan blade angle, use solid and reliable, good heat dissipation effect, coherence is big, the mechanical rotation or the resistance of start are little, less energy consumption, and rotating torque is big, be very beneficial for the rotation of wind wheel, the just rotatable down generating of low wind speed, wind energy can fully be developed, on wind-driven generator, refill and join electrical storage device, can realize round-the-clock power supply, energy-conservation, environmental protection, consumption reduction, easily penetration and promotion, very good through trial effect, can satisfy room lighting in the daily life fully, see the usefulness of the illuminating lamp of TV and work and study and other household electrical appliance etc., the utility model non-environmental-pollution, cost is low, easily produce and install, for the exploitation of wind-force and wind-driven generator popularize and pioneering contribution is made in use.
