Description
Technical field
The present invention relates to a kind of wind-driven generator, particularly a kind of vertical shaft right angle transmission wind-driven generator with double fan blade.
Background technique
Wind energy is the inexhaustible a kind of green power source of nature, all is the single-group type structure but utilize the fan blade of collecting folk songs of wind energy power both at home and abroad at present, and a kind of is the wind-driven generator that fan blade and generator meet at right angles and the generator level is installed; Normally this form of large-scale wind energy generator, another kind are fan blade and generator vertical installing type wind-driven generator, and the wind energy power machine blade that first kind of mode installed is directly to be connected rotation with generator; Though fan blade is vertical with wind direction; Wind energy transformation is that the efficient of mechanical energy is high, but generator power is big more, and the diameter of fan blade is big more; Installation difficulty and installation requirement are high more; Second kind of fan blade and the vertically arranged wind-driven generator of generator receive structural limitations because of fan blade, and fan blade and wind direction be not that the right angle is stressed, and wind energy transformation is that the mechanical energy conversion ratio is low; Rectilinear fan-blade wind energy generator is rested on the miniaturization basis, fan blade rotation phenomenon not when above-mentioned two kinds of wind-driven generators all exist wind speed to be lower than 5 meter per seconds.
Summary of the invention
Technical problem to be solved by this invention for this reason is; Overcome at present existing fan blade and generator meets at right angles and there are technological deficiency in wind-driven generator, fan blade and the generator vertical installing type wind-driven generator of the installation of generator level; Provide a kind of simple in structure, vertical installing type wind energy power machine blade is met at right angles, and can when wind speed is lower than 5 meter per seconds, rotate generating; Low wind speed moment of torsion increases, the high wind speed vertical shaft right angle transmission wind-driven generator with double fan blade stably that turns round.
In order to achieve the above object, the technological scheme of the present invention's employing is: a kind of vertical shaft right angle transmission wind-driven generator with double fan blade comprises drain pan, vertical type generator, generator main vertical shaft; Column, the main shaft umbrella gear reverses fan blade, bevel pinion; Upper casing, clockwise fan blade, large bevel gear; First unilateral bearing, second unilateral bearing, its invention has following characteristic.
1: make vertical type generator rotate generating and drive by clockwise fan blade and reverse fan blade alternate rotation by certain orientation; Vertical type generator is installed in bottom, drain pan the inside; The generator main vertical shaft is housed above the vertical type generator, and the outside of generator main vertical shaft is a column, inboardly below the top of column 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.
One end of 2: the first fan blade transmission shafts 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 through first pivot pin; The outer ring of first unilateral bearing is connected with the endoporus of bevel pinion through second pivot pin, bevel pinion and the engagement of main shaft bevel-gear right-angle, and the outer ring of clutch shaft bearing group is connected with upper casing.
One end of 3: the second fan blade transmission shafts 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 through the 4th pivot pin; The outer ring of second unilateral bearing is connected with the endoporus of large bevel gear through the 3rd pivot pin, large bevel gear and the engagement of main shaft bevel-gear right-angle, and the outer ring of second bearing pack is connected with upper casing.
Working principle of the present invention is such: when natural wind speed is lower than 5 meter per seconds and blows to clockwise fan blade; Moment that clockwise fan blade produces through the second fan blade transmission shaft directly by the reaction force of second unilateral bearing; Through large bevel gear and the engagement of main shaft umbrella gear; Drive the generator main vertical shaft, because the load of vertical type generator exists and wind speed is too low; And large bevel gear is equal with the identical number of teeth of main shaft umbrella gear size, and the moment that clockwise fan blade is transferred to above the generator main vertical shaft does not have to become big, and at this moment clockwise fan blade does not have the effect of extraneous power to be difficult to start rotation; But the present invention has installed the reverse fan blade at the homoaxial the other end of clockwise fan blade; Be that the nature wind speed is lower than 5 meter per seconds and blows to when reversing fan blade equally, first unilateral bearing be installed because of reversing the fan blade first fan blade transmission shaft above coaxial, bevel pinion is equipped with in the outer ring of first unilateral bearing; The diameter of bevel pinion is littler than main shaft umbrella gear diameter; And the bevel pinion gear ratio main shaft umbrella gear number of teeth is few, the engagement of the same right angle of bevel pinion and main shaft umbrella gear, so bevel pinion has alleviated reverse fan blade moment of rotation with main shaft umbrella gear generation speed ratio; Make and reverse fan blade and can be lower than under the effect of wind-force of 5 meter per seconds quick starting at wind speed and rotate; Also make simultaneously clockwise fan blade lose load and rotate, reverse fan blade under wind action power, the generation moment of torsion is delivered on the bevel pinion that is connected with the first unilateral bearing outer ring through the reaction force of first unilateral bearing; Through bevel pinion and the engagement of main shaft umbrella gear; Make with the main shaft umbrella gear to be connected the rotation of generator main vertical shaft, the vertical type generator generating is because of 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; Since 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, again can drive main shaft umbrella gear and the rotation of generator main vertical shaft 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 big utilization.
As optimal design; This under the effect of wind-force clockwise fan blade with reverse fan blade and rotate the generator work that drives simultaneously; But clockwise fan blade is discontinuous mutually with reverse fan blade rotating speed; 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 arranged when wind speed is lower than 5 meter per seconds.
