Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Among the figure: 1-side of a ship wing choke plate, 2-connecting rod, 3-rotary drive mechanism, 4-tail vane, 5-wind wheel, 6-center king-post, 7-anemoclinograph, the 8-bearing of going off course, 9-PLC, 10-retarder, 11-upper flange plate, 12-lower flange.
A kind of vertical axis aerogenerator side of a ship wing structure, comprise vertical axis aerogenerator, this vertical axis aerogenerator comprises center king-post 6 and the wind wheel 5 that is connected with the center king-post, it is characterized in that being provided with side of a ship wing choke device in a side of this vertical axis aerogenerator, this side of a ship wing choke device is connected with the wind direction Yawing mechanism by connecting rod 2, is rotatably connected between described center king-post 6 and the connecting rod 2.According to an embodiment of the present utility model, described or side of a ship wing choke device is side of a ship wing choke plate 1 or side of a ship wing choke curtain.Described wind direction Yawing mechanism comprises control unit and the anemoclinograph 7 that is connected with control unit, these center king-post 6 two ends are equipped with a rotary drive mechanism 3, by a connecting rod 2 and the connection of corresponding rotary drive mechanism, described control unit is connected with rotary drive unit 3 respectively at the two ends of described side of a ship wing choke plate or side of a ship wing choke curtain.The width of described side of a ship wing choke plate 1 or side of a ship wing choke curtain is 1/10 ~ 1/12 of wind wheel rotating diameter, and length is corresponding with wind wheel length.Angle between choke plate and the connecting rod is that the length according to connecting rod designs, but the edge of choke plate becomes 30 ° of angles to the line of rotation round with wind direction.According to preferred embodiment of the present utility model, described side of a ship wing choke plate 1 outside is circular arc, and the spacing between side of a ship wing choke plate 1 inboard and wind wheel 5 outer rims is 100 ~ 500mm.As shown in Figure 4, described rotary drive mechanism comprises the driftage bearing 8 that is arranged on the king-post of center, control unit 9 is connected with this driftage bearing 8 by driving mechanism, the driftage bearing is connected with connecting rod 2 by connector, also be provided with an anemoclinograph 7 on this center king-post 6, this anemoclinograph 7 is connected with control unit.According to this embodiment, control unit is PLC.
The wind speed and direction that PLC records according to the custom flow direction vane, control driving mechanism drive 8 rotations of driftage bearing, thereby so that side of a ship wing choke plate 1 rotates to special angle, realize specific function.
As shown in Figure 3, wind wheel rotates after being subject to wind-drive, wind direction as shown by arrows in FIG., suppose that wind wheel rotates clockwise under the wind-force effect, then for wind wheel, the wind direction on right side plays the effect that drives the wind wheel rotation, namely as the power of wind wheel, so the right side of windward side is called as the power side, and the wind direction in left side plays the effect that hinders the wind wheel rotation, namely as the resistance of wind wheel, therefore the left side of windward side is called as the resistance side, and the opposite direction of supposing wind direction is that the forward of y axle is set coordinate axes, and wind wheel is divided into first quartile, the second quadrant, third quadrant and fourth quadrant.
When side of a ship wing choke plate 1 rotates to as shown in the figure the second quadrant position, can block most of resistance wind direction, playing increases the rotating speed moment of torsion, the effect that improves generated energy 30%-40%.When be the wind comes from by the front, the face that is obstructed that the left side turns clockwise wind wheel stops flows direction of the wind comes from, and arrive part second quadrant and whole first quartile with the wind water conservancy diversion this moment, makes wind wheel not be subjected to the impact of resistance air quantity, makes stressed the increasing to about 1.78 times of rotation of wind wheel.This side of a ship wing choke plate 1 can adopt folding curtain type, and the big or small capable of regulating increase and decrease that changes window changes 1.78 value; Change this choke plate 1 angle of swing in the second quadrant, can change or adjust simultaneously the value of increase and decrease 1.78; Side of a ship wing choke plate 1 is as long as (no matter being clockwise or the inhour rotation) this structure technology can both play efficient, rotating speed, running torque and the wind power factor design load of increase by 1.78 in the windward side.The edge of its centre board wing choke plate 1 and facing the wind to opposite direction be leeward between angle [alpha] be 20 ~ 40 degree for good, wherein the optimum position is 30 degree.
When side of a ship wing choke plate 1 rotates to as shown in the figure first quartile position, can block most of power wind direction, play wind wheel is slowed down until brake, i.e. aerodynamic brake function generally is used for when wind speed during greater than 18m/s the effect of play deceleration, braking.The impact of keeping out the wind that makes wind wheel 8 be subject to choke plate in this position can reduce rotational speed, can also play the effect of brake in the certain hour; Change the slow minimizing that the choke plate rotary angle position can change the rotational speed of wind wheel 8, if choke plate 1 is the aperture position of folding curtain type structural change curtain, can slowly reduce rotational speed equally.Equally, take the edge of side of a ship wing choke plate 1 and facing the wind to opposite direction be leeward between angle as 20 ~ 40 degree as good, wherein the optimum position is 30 to spend.
When string wing choke plate 1 rotates to third quadrant, belong to the wind face, generally in following situation, use: one, come when this position, can protect this choke plate 1 structure at high wind temporarily, increase wind loading rating; Two, make wind wheel return to phenomenon without the string wing structure.
According to another embodiment of the present utility model, also be provided with two tail vanes 4 at the opposite side of vertical wind power generator, described two tail vanes 4 are connected by the two ends of connecting rod with this vertical axis aerogenerator center king-post respectively.The area of tail vane plays the effect of wind direction driftage more than or equal to the area of 1.5 times of choke plates, can be to replace PLC and aerovane to play wind direction driftage effect with tail vane in the small-sized fan, and large fan plays the driftage effect with PLC and aerovane.
