Description
Technical field
The present invention relates to a kind of device that utilizes wind energy, particularly a kind of device that utilizes kite power generation.
Background technique
At present, known carrousel kite power generation machine is made up of traffic cycle, kite, hawser, multiplying gear, generator, change power transmission system, control system; Not enough below existing: the traffic cycle volume is too big; The kite attitude-control device flies in the air in company with kite together, and weight increases, and the energy demand that the control of kite attitude needs is provided with a cover electricity generating device separately; The control of kite attitude needs the complicated wireless remote controller of a cover, complex structure.
U. S. Patent U.S.6072245 discloses the device that is used to utilize wind energy, comprises a plurality of kites that are connected in the high strength cord that forms ring-type.Kite replaces the route that descends from the route to of a rising under the effect of wind-force, rope is rotatablely moved along equidirectional all the time.Each kite is connected to high strength cord to transmit mechanical energy and to be connected to a controlling rope cable system to adjust the angle of attack of each kite.High strength cord makes the pulley rotation with generating.The control rope is used to make each kite to remain on such position, on the route that rises, makes and draw on the reversible wind direction of kite that on second position of descent path, kite descends with the wind.U. S. Patent U.S.6072245 is disclosed to be used for utilizing the high-strength rope of the device both sides of wind energy inevitably to have error in length, and this device of wind energy that utilizes moves continuously, and error in length accumulates continuously, causes kite disequilibrium gradually.
Summary of the invention
In order to reduce kite power generation device fabrication cost, reduce the kite power generation cost, improve the above-mentioned defective of present known kite power generation machine, the present invention discloses a kind of new kite power generation system-automatic control kite group generator.
The contrast of the present invention and existing technology is characterized in that: automatic control kite group generator comprises automatic control facing the wind at least ten kites at angle and the cableway combination of a circular flow (being called for short automatic control kite group); Many circle rope multiple-roll transmission devices (being called for short many rope driving devices); At least two of cylinder numbers have been equipped with assistant starting in addition and have let device fly away.
The structure of automatic control kite group is seen Fig. 1 Fig. 2 Fig. 3 Fig. 4, comprises cableway (1), goes up backguy (2), pull-down line (3), kite body (4), and an end of last backguy (2) is concentrated the A point that is connected cableway (1); The other end of last backguy (2) is connected the upper end of kite body (4), and an end of pull-down line (3) is concentrated the B point that is connected cableway (1), and the other end is connected the lower end of kite body (4); The C point is the center line upper extreme point of kite body (4), and the D point is the center line lower extreme point of kite body (4), and AB line, AC line, CD line, BD line form articulated four pole mechanism; The AB line is a frame; The AC line is a rocking bar, and the CD line is a connecting rod, and the BD line is a rocking bar.For kite body is taken off smoothly, tandem promoter spring (5) between end of last backguy (2) and A point starts the two ends parallel connection tightrope (6) of spring (5), and the effect of tightrope (6) is a tensile elongation of accurately confirming to start spring (5).
During automatic control kite group flight stability; The characteristics of motion according to articulated four pole mechanism; The facing the wind angle β of angle α that facing the wind of the kite (N) of the following work done state of cableway (1) greater than the kite (P) of cableway (1) top return state; The suffered wind action power of kite (N) of the following work done state of cableway (1) is greater than the suffered wind action power of kite (P) of cableway (1) top return state; Cableway (1) moves along arrow (8), arrow (9), arrow (10), the indicated direction of arrow (11) continuously, and when kite (4) ran to the upper end of cableway (1), the characteristics of motion of abideing by articulated four pole mechanism reduced angle down with the wind automatically gradually; When kite runs to the axis of big motive power wheel (7) when following along arrow (8), kite is turned to by gravity effect to be hang, and kite (4) continues motion along arrow (8), receives wind to be transformed into level (M); Increase and start spring (5) and tightrope (6); The kite (M) that helps level is converted to the kite (N) of work done state; The startup spring (5) of hang kite and the startup spring (5) of level kite (M) are in contraction state; The startup spring (5) of work done state kite (N) and return state kite (P) is in extended state under the effect of wind-force; The effect of tightrope (6) is a tensile elongation of accurately confirming to start spring (5), starts spring or pressure spring that spring (5) also can be selected the form of reversing for use, and the pulling force that starts spring (5) approximately is three times of kite body (4) weight; A groove is opened at kite body (4) upper limb middle part, and groove holds cableway (1), makes cableway (1) and kite body (4) receive force direction more reasonable; Last backguy (2), pull-down line (3) are made the good semi-hard rod member of elasticity with composite material, and the good semi-hard rod member of elasticity of kite body (4) lower edge device prevents that they are intertwined mutually.Cableway (1) lower end is installed in the groove on the block rubber (7-2) of large drive wheel (7) outer rim; See Figure 14; Cableway (1) upper end is free-floating with the wind; Large drive wheel (7) outer ring is the annulus channel-section steel made from channel-section steel (7-1), and the cableway of circular flow (1) drives large drive wheel (7), transmission shaft (13), many rope driving devices and generator (19) generating.In order to guarantee that kite locates safety at big motive power wheel (7), catch net (12) is installed in big motive power wheel (7) both sides.
Many circle rope multiple-roll transmission devices are by transmission rope (20), at least two cylinders (15), (16), expansion tightening wheel (21) and axle thereof, bearing, bearing support, frame; Component are formed; The many circles of transmission rope (20) are wrapped in the ring shaped slot (30) of at least two cylinders (15), (16) outer rim, and the purpose that transmission rope (20) adopts many circles to be wrapped on a plurality of cylinders is in order to increase frictional force, according to test; On two cylinders, twine eight circles and can satisfy the transmission requirement; The winding method of transmission rope (20) on cylinder (15), cylinder (16): transmission rope (20) is walked around cylinder (15), walks around cylinder (16) again, walks around cylinder (15) again; Walk around cylinder (16) again ... The number of turns of twining increases frictional force and increases, and the transmission of many circle rope multiple-rolls has two kinds of closed loop and open loop forms, and forward winding method and intersection winding method are arranged respectively in these two kinds of forms.
Forward winding method is as shown in Figure 7 for two cylinders of many circle rope multiple-roll transmission closed loop; Forward winding method is as shown in Figure 8 for two above cylinders of many circle rope multiple-roll transmission closed loop.
Two cylinders intersections of many circle rope multiple-roll transmission closed loop winding method is as shown in Figure 9; Two above cylinders intersection winding methods of many circle rope multiple-roll transmission closed loop are shown in figure 10.
