Description

The breeze wind-power generator that a kind of impeller horizontally rotates

Technical field

The utility model belongs to a kind of small-sized breeze wind-power generator.

Background technique

The common impeller of existing small wind-driven generator vertically rotates, and blade directly is connected on the generator shaft, this arrangement has just determined it to start that rotating speed is relative with rated speed has relatively high expectations, need the wind-force more than 4 grades to work, make wind energy not to be fully utilized, adaptability is relatively poor; And because its rotating speed is higher, so vibration is big, noise rings, and particularly when wind direction was unstable, yawing mechanism changed frequent, vibrates greatlyyer, and is easy to generate the hinge cable phenomenon of blade.

Summary of the invention

But the purpose of this utility model be to design a kind of small-sized using scope extensively, start easily, breeze wind-power generator that quiet impeller efficiently horizontally rotates.

Technical solution of the present utility model is: it is made up of blade, connecting rod, the impeller plate, wheel shaft, generator, gear speeder and pylon, wherein gear speeder is arranged on tower top, its low speed input shaft links with the vertical wheel shaft that stretches out that makes progress, the impeller plate is arranged on the wheel shaft, and it is perpendicular with wheel shaft, the impeller plate is provided with the connecting rod that is in it on same horizontal plane, blade is located on the connecting rod, generator is located on the pylon, and the high speed output shaft of its generator shaft and gear speeder links.Blade is accepted wind energy, the impeller disc spins, the output torque, cause on the speed increaser of pylon from the impeller upper end by the torque of wheel shaft impeller output, pass through the raising speed effect of speed increaser then, drive generator and make high speed rotating, thereby send galvanic current accumulator---charge in batteries.

As a kind of optimal way, described blade vertically is located on the described connecting rod, and it is the square tabular body that a side vertical side is provided with the bending wing that bends inwards.The bending cambered surface of the described bending wing is semicircle.Being in operation to make full use of the air swirl that the bending wing produces when rotated, and impeller is played acceleration.

Wheel shaft is protected in installation and maintenance for convenience simultaneously, and wheel shaft is provided with axle sleeve outward.

Described generator is the Nd-Fe-B rare earth permanent magnetic material generator.It has that efficient height, volume are little, in light weight, specific power big, rise to establish and press low etc. the characteristics of rotating speed, can increase annual electricity generating capacity and increase and effectively use fate; This generator output voltage is constant simultaneously, is not subjected to the influence of wind speed size variation, can avoid storage battery to cause damage because of overcharging.

The utility model has the advantages that: it has, and to start rotating speed low, the characteristics that torque is bigger, start easily, under 2 grades of left and right sides wind-force, just can start the operation generating, enlarge wind-driven generator and can utilize the use fate and the effect in district, and improved a year effective generated energy, simple in structure, easy for installation, use quiet efficient.
