Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated: windmill is comprised of main body and fan blade steering control system; Main body comprises pedestal 1, plane needle bearing 2, trailing arm 3, fan blade 4, central shaft 5, brace 7, lightning-arrest mechanism 8, transmission shaft 20 and speedup transmission case 22; Fan blade steering control system mainly contains gear control box 9, control passing shaft A6, control passing shaft B21, wind speed and direction induction system, wind direction aligning adjust system 11; Pedestal 1 is fixed on ground, plane needle bearing 2 is positioned on pedestal 1 and with lower trailing arm and is connected, fan blade is connected with trailing arm 3, lower trailing arm is connected with gear control box 9, and gear control box 9 is positioned at central shaft 5 bottoms, and lightning-arrest mechanism 8 is arranged at the top of central shaft 5, gear control box 9 bottom connection for transmission axles 20, transmission shaft 20 is connected with speedup transmission case 22, and speedup transmission case 22 connects pto＝power take-off 10, as shown in Figure 1.
Below in conjunction with specific embodiment, the present invention is further described, as shown in Figure 1, can be for two-layer when the number of plies of the fan blade of windmill, each trailing arm 3 is connected with central shaft 5, and strong by brace 7, makes integral body more firm.
When windmill blowing after startup due to wind, wind speed and direction induction system passes to wind direction by the wind speed and direction information collecting and aims at adjust system 11, wind direction aligning adjust system 11 is controlled passing shaft B21 control centre tooth 12 by rotation and is taken turns rotation, allow fan blade 4 with best angle windward, wherein one group of fan blade is vertical with wind direction, organizes therewith fan blade parallel with wind direction about axisymmetric another group fan blade in center, and all the other other two groups of fan blades are mutually vertical, and be 45° angle with wind direction, as shown in Figure 2.Now, wind direction is aimed at adjust system 11 and will be controlled passing shaft B21 locking.The moving fan blade 4 of wind is around central shaft 5 revolution, because central gear 12 is now fixing, central gear can force intermediate gear A15 and intermediate gear B16 to rotate, and then drive pinion A18 and pinion B17 to rotate, thereby rotate with the cone gear 19 of pinion A18 engagement, finally by controlling passing shaft A6, force fan blade 4 rotations.Due to the setting of gear ratio, the revolution of fan blade and the ratio of rotation are set as to 2 ︰ 1, i.e. 180 ° of 360 ° of its rotations of the every revolution of fan blade.When wind direction changes, speed wind direction induction system passes to wind direction by the wind speed and direction information collecting and aims at adjust system 11, wind direction is aimed at adjust system 11 and is controlled 12 rotations of passing shaft B21 control centre gear by rotation, allow fan blade 4 with best angle windward after, and will control passing shaft B21 locking.
Because the moving fan blade 4 of wind revolves round the sun, drive transmission shaft 20 to rotate, transmission shaft 20 connects speedup transmission case 22, improves rotational velocity, and then from pto＝power take-off 10 outputs, by wind energy transformation, is mechanical energy.Pto＝power take-off 10 can be connected with generator, and mechanical energy is converted into electric energy, also can be for water pumping of the wind-force.
Wind speed and direction induction system can be controlled the elevator mechanism being connected with fan blade by control circuit, when sensor detects that wind scale is excessive may threaten blower fan stable, with calling control circuit, elevator mechanism is fallen; When wind scale drops to security value (s), by control circuit, elevator mechanism is risen.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, with reference to embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.Without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements are all in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
