Abstract
The utility model discloses a horizontal shaft magnetic suspension wind driven generator, including fixed portion and rotating part, its characterized in that: the fixed portion generator that includes round the annular clamped magnetic ring that the level placed and be located the afterbody, fixed magnetic ring include preceding fixed magnetic ring, after -fixing magnetic ring, the main shaft made in the intra -annular permanent magnet of fixed magnetic ring circle of the rotating part suspension that includes a level setting and locate the front -end of spindle, lie in the outer impeller of fixed magnetic ring. Horizontal shaft magnetic suspension wind driven generator, the beneficial effect who has is: simple structure adopts the magnetic suspension setting, and in the rotatory portion rotating back of getting up, fixed portion and rotating part be the contactless each other, and small friction reduces the maintenance cost of fan, effectively reduces the start -up wind speed of fan for the efficiency that the wind energy changed the electric energy into improves greatly.
Description
Technical field
The utility model relates to wind power generation field, particularly a kind of horizontal shaft magnetic suspension wind driven generator.
Background technique
Wind-driven generator is the one in generator, belongs to environment protection type generation of electricity by new energy machine.Wind-driven generator is the dynamic power machine of mechanical work by Wind resource change, also known as windmill.In a broad sense, it is a kind of is thermal source with the sun, take air as the heat energy utilization motor of medium.The power of wind-power electricity generation, completely by the power decision of wind-driven generator, always want to select larger wind-driven generator, and this is incorrect.Current wind-driven generator just to storage battery charging, and is got up power storage by storage battery, and size and the storage battery size of people's final utilization electric power have closer relation.The size of power more depends primarily on the size of air quantity, and is not only the size of head power.
Fully permanent magnetic floating wind generator can improve wind energy power amount greatly, accomplish " light breeze starts; breeze wind ", threshold wind velocity is made to be reduced to below 1.5m/s, generating wind speed is 2m/s, like this, accounting for China's area 68%, the wind energy of mean wind velocity >=3m/s can utilize district and comparatively enrich district, than traditional wind can increase year generating dutation 1000 little time/year.Compare with traditional wind-driven generator, under identical wind speed, fully permanent magnetic floating wind generator, under equal wind speed, improves generated energy about 20% than traditional wind, wind energy utilization is improved greatly, and wind energy turbine set operating cost also can be made to decline about 50%.
The shortcomings such as existing magnetic suspending wind turbine generator often also exists complex structure, and wind energy utilization is low.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, the horizontal shaft magnetic suspension wind driven generator that wind energy utilization is high.
For achieving the above object, the technological scheme that the utility model proposes is: a kind of horizontal shaft magnetic suspension wind driven generator, comprises standing part and rotating part, it is characterized in that:
The ring that described standing part comprises horizontal positioned is fixed magnet ring and is positioned at the generator of afterbody; Described fixing magnet ring comprises front fixing magnet ring, rear fixing magnet ring;
Described rotating part comprises a horizontally disposed main shaft being suspended in the permanent magnet in fixing magnet ring annulus and making, and is located at front-end of spindle, is positioned at the impeller outside fixing magnet ring; Described main shaft is provided with support disk, and described support disk is provided with front rotation magnet ring and rear rotation magnet ring; Described front rotation magnet ring and rear rotation magnet ring are between front fixing magnet ring and rear fixing magnet ring; Described front fixing magnet ring and front rotation magnet ring, the magnetic pole that rear fixing magnet ring is relative with rear rotation magnet ring is identical, or described front fixing magnet ring and front rotation magnet ring, and the magnetic pole that rear fixing magnet ring is relative with rear rotation magnet ring is different;
The face magnetic pole that described fixing magnet ring is relative with main shaft is different; And lower half portion of described fixing magnet ring and main shaft lower half portion have corresponding annular groove, described annular groove is placed with at least one non magnetic bead.
Preferably, described non magnetic bead number is 3-20, determines according to generator size.
Preferably, described support disk is that plastics are made.
Adopt technique scheme, horizontal shaft magnetic suspension wind driven generator described in the utility model, the beneficial effect had is:
1) horizontal axis wind-driven generator described in the utility model, structure is simple, employing magnetic suspension is arranged, after rotating part rotates, standing part does not contact each other with rotating part, and frictional force is little, reduces the maintenance cost of blower fan, the threshold wind velocity of effective reduction blower fan, makes wind energy transformation become the efficiency of electric energy greatly to improve;
2) lower half portion of fixing magnet ring, namely second annulus middle has an annular groove, groove is placed several non magnetic bead, makes main shaft and fixing magnet ring only form fraction by non magnetic bead and contacts, such minimizing main shaft starts resistance when rotating, and reduces the loss of wind energy.
