Abstract
The utility model discloses a wind power generator, comprising a spindle (1), which is connected with a generator (3) through a transmission mechanism (2), and a blade is connected with the spindle (4), said blade is the trapezoidal blade, the top of the trapezoid is connected with the spindle (1), an upper side (5) is torsional with a lower side (6), and the torsion angle is 25 to 35 degrees. The blade is not restricted by wind direction and has a big wind area, thereby making full use of wind power, with high conversion rate of wind energy; one side of the blade is connected with the whole of the spindle, and the torque generated is small, resulting in small wind energy loss and high efficiency of the generator in unit space. At the same time, the utility model has the advantages of simple structure, and easy production, low cost and convenient maintenance.
Description
Technical field:
The utility model relates to a kind of wind-driven generator, especially a kind of simple in structure, can make full use of wind-force, be the wind-driven generator of mechanical energy with wind energy transformation.
Background technique:
At present, along with the scarcity day by day of natural resourcess such as oil, various energy-conserving products arise at the historic moment, and wind-driven generator is exactly one of them.The structure of existing wind-driven generator is to be provided with main shaft (pto), is connected with helical blade with the main shaft cantilever.When wind behind helical blade, helical blade rotates, rotate thereby drive output shaft, be mechanical energy with wind energy transformation, by transmission device, make the generator work that is connected with output shaft, existing helical blade type wind power generation machine exists following shortcoming:
1. complex manufacturing technology, cost height and maintenance difficult;
2. wind must be blown over just from the top of blade and can be made blade rotation, and a large amount of wind will pass from the space of blade, and the wind power utilization rate is low, and the wind-driven generator whole efficiency is low;
3. the moment of torsion that produced of the cantilever Placement between helical blade and the main shaft is big, directly causes energy loss big, and generator efficiency is low, and floor space is big, and consume material is many.If will reach ideal engine efficient, must increase the size of helical blade.
Summary of the invention:
The utility model is at technical problems such as existing in prior technology wind energy-mechanical energy transformation efficiency are low, provide a kind of simple in structure, can make full use of wind-force, be the wind-driven generator of mechanical energy with wind energy transformation.
Technical solution of the present utility model is: a kind of wind-driven generator, main shaft 1 is arranged, main shaft 1 joins by driving mechanism 2 and generator 3, be connected to blade 4 with main shaft 1, described blade 4 is trapezoidal, trapezoidal upper topside and main shaft 1 join, and upper side edge 5 reverses mutually with lower side 6, and reversing angle is 25～35 degree.
Described blade 4 laterally, crooked on vertically, the torsional direction of bending direction and upper side edge 5 is opposing.
Described blade 4 locates to be provided with wind cutting angle 7 with the bottom on the torsional direction one side in the same way.
The gear 8,9 of described driving mechanism 2 for being meshed, gear 8 joins with main shaft 1, and gear 9 joins with generator 3.
Described main shaft 1 is movably connected on the framework 10, and two ends are connected to gear 8 respectively up and down, and the both sides of each gear 8 are engaged with gear 9 respectively, and the generator 3 that joins with gear 9 is fixed on the framework 10.
The utility model is compared with prior art, and maximum difference is to be fixedly connected with the trapezoid blade that a plurality of both sides are up and down reversed mutually with output shaft, blade be not limited by wind direction and blowing area big, can make full use of wind energy, wind energy transformation rate height; One side of blade is connected with main shaft is whole, and the wind energy loss is little, the generator efficiency height in the unit space.Simultaneously, product structure is simple, making is easy, and cost is low, easy to maintenance.
