Abstract

The invention relates to a method for utilizing the wind energy at high altitude, which obtains wind energy by flying a rotating wind wheel at high altitude; when the wind power at high altitude leads the wind wheel to rotate, an upper driving wheel integrated with the wind wheel is rotated at the same time, and the rotating energy is transmitted to a lower driving wheel arranged on a ground worktable by pulling a driving belt (chain). A generator or other load devices can be connected on the lower driving wheel.

Description

The method that high altitude wind energy utilizes
The present invention relates to a kind of Wind Power Utilization method, particularly a kind of method of using kite to obtain high altitude wind energy.
Present known wind energy facility can only be erected at ground or with high tower wind wheel be risen in the air, because the setting height(from bottom) of wind wheel is very limited, can't obtain the high altitude wind energy than the big manyfold in ground, and the device fabrication cost is higher.
The purpose of this invention is to provide and a kind ofly can obtain high altitude wind energy easily, the method that the high altitude wind energy that its equipment manufacturing cost is cheap utilizes.
The present invention is achieved in that wind energy catches that to have adopted rotation wind wheel, its cross-sectional configuration be the S type, is made up of the column type blade of two axis misalignment semicircular, and this wind wheel is vertically to be installed on ground when conventional use the at present, belongs to vertical axis windmill.Because this wind energy conversion system can produce the asymmetric rotational air-flow around wind wheel when rotating, cause rotating shaft position a lateral thrust to occur, this lateral force strengthens along with increasing of rotating speed, operation for large scale wind power machine has bigger harm, thereby has influenced its generally use to a certain extent.If this wind wheel horizontal positioned, when wind-force rotated wind wheel up, this lateral thrust had just become the power that makes progress, and promptly became lift, and a kind of rotary-type kite utilizes this principle to make exactly.The present invention is similar to this runner kite, it is to have installed drive wheel on wind wheel additional, and the pulling cable of kite changed into annular transmission belt or Transmitted chains, when wind-force makes the runner kite rise to the high-altitude, S type wind wheel drives goes up the drive wheel rotation, wind wheel also provides the lift that is highly profitable for system in capturing wind energy.This lift is when assurance itself can not fall, also will draw driving belt or Transmitted chains tension by last drive wheel and surface-based lower driving wheel, and rotating force is sent to ground by the high-altitude, corresponding load equipment such as generator etc. can be connected on the drive wheel of ground.
Owing to such scheme, greatly reduce the manufacturing and the operating cost of wind energy facility, effectively utilized high altitude wind energy.
Below in conjunction with Figure of description the present invention is done detailed explanation.
Fig. 1 is a work schematic representation of the present invention.
Fig. 2 is the partial schematic sectional view of rotating wind wheel.
Fig. 3 is that the A-A that rotates wind wheel analyses and observe diagrammatic sketch.
Among the figure 1, traction kite 2, wind wheel end axle 3, pulling cable 4, hitch frame 5, support plate 6,8, driving belt 7,20,21, wind wheel 9, Equilibrator 10, vertical tail, 11, horizontal tail 12, go up drive wheel 13, rotatingshaft 14, support 15, worktable 16, axle sleeve 17, central shaft 18, lower driving wheel 19, traction driving belt (chain) 22, belt wheel
In Fig. 1, belt wheel (22) is arranged on the wind wheel (20) (7) (21), by with the corresponding driving belt of belt wheel (22) (6) (8) each wind wheel being interconnected, the support plate (5) in the middle of the wind wheel (7) (20) designs for the intensity that increases wind wheel.In order to guarantee that each wind wheel also can stable operation when the high wind, can install additional on each wind wheel with axle (2) is the Equilibrator (9) of center of circle activity, under the effect of wind-force, horizontal tail (11) makes Equilibrator (9) be in the state of level of approximation, vertical tail, (10) can allow each wind wheel keep over against the wind comes from, to reduce the situation that wind wheel (20) (7) (21) swings and tilts.
The drive wheel of bottom (18) is by rotatingshaft (13), and support (14) is installed on the worktable (15), and central shaft (17) is fixed on ground, and (16) are to be fixed on the axle sleeve that cooperates with central shaft (17) on the platform.When wind direction changed, worktable (15) can be that rotate with the wind in the center of circle with central shaft (17) under the traction of traction driving belt (chain) (19), makes lower driving wheel (12) (18) remain linear state.
The present invention is when using single wind wheel, directly drive when wind energy drives wind wheel (21) rotation and go up drive wheel (12) rotation, as use the string data wind wheel, the moment of rotation that wind wheel (7) (20) obtains needs through the belt wheel (22) at two ends and connects belt (6) (8) and wind wheel (21) is delivered on the drive wheel (12).By matching with last drive wheel (12), have the traction driving belt (chain) (19) of traction and two functions of transmission power, drive lower driving wheel (18) and rotate, catch energy thereby finished from the high-altitude, be resent to the process on ground.The load equipment that is installed on the worktable (15) can be connected by the speed change gear that is connected with lower driving wheel (18), also can directly be connected in the rotating shaft (13) with drive wheel (18) one.
When the wind-force on ground is more weak, let the relatively large wind wheel kite of weight separately fly away and have certain difficulty, at this moment can finish by the traction kite (1) of Fig. 1 middle and upper part.The pulling cable (3) of top traction kite (1) is fixed on the hitch frame (4), and there is the corresponding axis hole of rotating shaft (2) with wind wheel (20) two ends the end of hitch frame (4), and wind wheel (20) can freely rotate in hitch frame.When initially letting fly away, earlier traction kite (1) small-sized relatively and that let fly away is easily let fly away the high-altitude, by the bigger wind-force in high-altitude, again wind wheel (7) (20) (21) is drawn high the height that can run well, the length of tow rope (3) will be determined according to wind conditions.Can save traction kite (1) at the bigger wind field of wind-force.Make for convenience and let fly away, two class kites all should be selected string data for use, and the number of combinations of each kite string can determine according to the power of wind energy conversion system, and are single or all can by tens even more combination.When selecting traction driving belt (chain) (19), should not select metal chain as far as possible, because of metal chain is heavier relatively, the high-altitude of wind wheel being let fly away last km with metal chain is unpractical, and metal chain has the easy triggered lightning accident of electric conductivity, so the metal Transmitted chains can only use in the low latitude.
In the practical application, folding and unfolding for the ease of wind wheel (7) (20) (21), can connect an auxiliary stay again near on the pulling cable (3) of hitch frame (4) position, when the pulling cable of traction kite (1) is strained hitch frame (4), this backguy is progressively emitted, whole string wind wheel is slowly risen, when regaining kite, then backguy is progressively regained, avoid letting fly away and the withdrawal process in damage wind wheel (7) (20) (21).After each wind wheel normal rotation entered working state, auxiliary stay at this moment should loosen, but still will be fixed in position, deviate from or rupture to cause whole kite to be taken place by the accident that wind blows away with the driving belt that prevents each wind wheel.
Because the wind-force in high-altitude is very big sometimes, in order to increase the mechanical strength of wind energy plant, kite all should avoid using soft fabric, should select glass fibre reinforced plastics and carbon fiber for use.In order to adapt to different wind-force, lower driving wheel (18) can be combined by the wheel of a plurality of different-diameters, with the convenient output speed of adjusting wind energy plant.
