Description

Vertical shaft right-angle drive wind-driven generator with double fan blade

Technical field

The utility model relates to a kind of wind-driven generator, particularly a kind of vertical shaft right-angle drive wind-driven generator with double fan blade.

Background technique

wind energy is the inexhaustible a kind of green power source of nature, but utilizing the fan blade of collecting folk songs of wind energy power both at home and abroad at present is all the single-group type structure, a kind of is the wind-driven generator that fan blade and generator meet at right angles and the generator driven water safety fills, normally this form of large-scale wind energy generator, another kind is fan blade and generator vertical installing type wind-driven generator, wind energy power machine blade and generator that first kind of way is installed are direct connection of rotatings, although fan blade is vertical with wind direction, wind energy transformation is that the efficient of mechanical energy is high, but generator power is larger, the diameter of fan blade is larger, installation difficulty and installation requirement are higher, the vertically arranged wind-driven generator of the second fan blade and generator is subject to structural limitations because of fan blade, and fan blade and wind direction are not that the right angle is stressed, wind energy transformation is that the mechanical energy conversion ratio is low, the vertical fan blade wind-driven generator is rested on the miniaturization basis, fan blade rotation phenomenon not when all there is wind speed lower than 5 meter per second in above-mentioned two kinds of wind-driven generators.

Summary of the invention

Technical problem to be solved in the utility model is for this reason, overcoming at present, there is technological deficiency in existing fan blade with generator meets at right angles and the generator driven water safety fills wind-driven generator, fan blade and generator vertical installing type wind-driven generator, provide a kind of simple in structure, vertical installing type wind energy power machine blade is met at right angles, and can rotate at wind speed generating during lower than 5 meter per second, low wind speed moment of torsion increases, the vertical shaft right-angle drive wind-driven generator with double fan blade of high wind speed smooth running.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of vertical shaft right-angle drive wind-driven generator with double fan blade comprises drain pan, vertical type generator, the generator main vertical shaft, column, main shaft umbrella gear, reverse fan blade, bevel pinion, upper casing, clockwise fan blade, large bevel gear, the first unilateral bearing, the second unilateral bearing, its invention has following characteristics.

1 ,Making vertical type generator rotate generating by certain orientation is driven by clockwise fan blade and reverse fan blade alternate rotation, vertical type generator is arranged on bottom, drain pan the inside, the generator main vertical shaft is housed above vertical type generator, the outside of generator main vertical shaft is column, below the top of column, the inboard is connected with bearing outer ring, bearing inner race is connected with the generator main vertical shaft, and the main shaft umbrella gear is equipped with on generator main vertical shaft top.

2 ,One end of the first fan blade transmission shaft is connected with the reverse fan blade, the other end is connected with clutch shaft bearing group inner ring, the first unilateral bearing inner ring is connected with the first fan blade transmission shaft by the first pivot pin, the outer ring of the first unilateral bearing is connected with the endoporus of bevel pinion by the second pivot pin, bevel pinion and the engagement of main shaft bevel-gear right-angle, the outer ring of clutch shaft bearing group is connected with upper casing.

3 ,One end of the second fan blade transmission shaft is connected with clockwise fan blade, the other end is connected with the second bearing pack inner ring, the second unilateral bearing inner ring is connected with the second fan blade transmission shaft by the 4th pivot pin, the outer ring of the second unilateral bearing is connected with the endoporus of large bevel gear by the 3rd pivot pin, large bevel gear and the engagement of main shaft bevel-gear right-angle, the outer ring of the second bearing pack is connected with upper casing.

working principle of the present utility model is such: when natural wind speed blows to clockwise fan blade lower than 5 meter per seconds, moment that clockwise fan blade produces by the second fan blade transmission shaft directly by the reaction force of the second unilateral bearing, by large bevel gear and the engagement of main shaft umbrella gear, drive the generator main vertical shaft, because load existence and the wind speed of vertical type generator are too low, and large bevel gear equates with the identical number of teeth of main shaft umbrella gear size, the moment that clockwise fan blade is transferred to above the generator main vertical shaft does not become large, at this moment clockwise fan blade does not have the effect of extraneous power to be difficult to the starting rotation, but the present invention has installed the reverse fan blade at the homoaxial the other end of clockwise fan blade, being the nature wind speed equally blows to when reversing fan blade lower than 5 meter per seconds, the first unilateral bearing has been installed because reversing fan blade the first fan blade transmission shaft above coaxial, bevel pinion is equipped with in the outer ring of the first unilateral bearing, the diameter of bevel pinion is less than main shaft umbrella gear diameter, and the bevel pinion gear ratio main shaft umbrella gear number of teeth is few, the same right angle engagement of bevel pinion and main shaft umbrella gear, therefore bevel pinion and main shaft umbrella gear generation speed ratio has alleviated reverse fan blade moment of rotation, make reverse fan blade can wind speed lower than the effect of the wind-force of 5 meter per seconds under quick starting rotate, also making simultaneously clockwise fan blade lose load rotates, reverse fan blade under wind action power, producing the reaction force of moment of torsion by the first unilateral bearing is delivered on the bevel pinion that is connected with the first unilateral bearing outer ring, by bevel pinion and the engagement of main shaft umbrella gear, make with the main shaft umbrella gear and be connected the generator main vertical shaft rotating, the vertical type generator generating, because energy is taken away in the vertical type generator acting, make the one group of fan blade rotating speed wherein that reverses fan blade and clockwise fan blade slack-off, due to the present invention with the large bevel gear of main shaft bevel-gear right-angle engagement with above the bevel pinion endoporus, unilateral bearing has been installed, make and reverse fan blade and two groups of fan blades of clockwise fan blade independent rotation that is independent of each other, can drive main shaft umbrella gear and generator main vertical shaft rotating again under the reaction of unilateral bearing, make clockwise fan blade and reverse fan blade always have one group to drive generator work, make wind energy reach again large utilization.

As optimal design, this under the effect of wind-force clockwise fan blade and reverse fan blade and rotate simultaneously the generator work that drives, but clockwise fan blade and reverse fan blade rotating speed are discontinuous mutually, can there be one group of fan blade to be in effective working state and drives generator work, make the wind energy power function that electric rate output be arranged during lower than 5 meter per second at wind speed.
