Description

A kind of wind energy switching mechanism and overhead wind power generator

Technical field

The utility model relates to the wind energy power technology field, is converted to the mechanism of electric energy especially for the kinetic energy that the lightweight aircraft such as kite or levitating parachute are produced when the high-altitude flight.The utility model also relates to the overhead wind power generator that is provided with described wind energy switching mechanism.

Background technique

At present, wind energy has developed into a kind of main alternative energy gradually, and is promoted in the world.

It is larger that traditional wind-power electricity generation is affected by the factors such as place and wind direction and wind velocity, and have shortcomings: at first, wind power plant often scale is larger, employing be the surface wind generator, need to take a large amount of soils; Secondly, wind-driven generator has certain negative effect to ecotope; In addition, wind-driven generator needs the high tower support just can enter apart from the height of ground hundreds of foot, and wind-force of this height is less, simultaneously also unstable, be difficult to aim at any time wind direction, actual conversion is lower, and the manufacture cost of conventional wind-driven generator, construction cost are all very high.

Compare with surface wind, upper wind wind-force is stronger, and is also more stable, is easier to prediction than surface wind simultaneously, therefore more and more comes into one's own.In prior art, utilize the mode of upper wind to mainly contain two kinds: the first is to build the power station aloft, in the high-altitude generating, then arrives ground by cable transfer; The second is to utilize aircraft first mechanical energy to be transported to ground, then is converted into electric energy by generator.

Wherein, first kind of way need to be stabilized in the high-altitude with equipment such as generator, cables, because weight is larger, therefore lift-off is highly limited, energy transformation ratio is low, and cost is high, reclaim difficulty, has the risk of falling, and there is not above shortcoming in the second way, becomes gradually the main R﹠D direction of utilizing high altitude wind energy.

publication number is the application for a patent for invention Publication Specification of CN101240778A, a kind of kite power generation method is disclosed, its working principle is that kite passes through Effector on the ground, change Windward angle, when the kite Surface Vertical during in air-flow, kite produces maximum pull because of wind resistance, kite passes through rope, the drawing generator generating, between the flyback return period, the kite Effector changes the kite Windward angle, its kite surface is approached be parallel to air-flow and resistance is minimum, generator switches to motor, provide energy by the outside, pull kite to return by rope, realize being interrupted and utilize high altitude stream to generate electricity, its deficiency just is, this method can only produce electric energy at the kite ascent stage, and need to consume extra energy drawing in kite back and forth, therefore the wind energy transformation rate is low.

Notice of authorization number discloses a kind of high-efficiency high-altitude kite electric generator for the utility model patent of CN201714574U, formed by a pair of high-altitude kite, generator set, high-altitude kite is pulled by cable, be in upper-middle troposphere during work, the flight attitude controlling device is installed on high-altitude kite, the control signal that can receive ground is regulated the angle windward of high-altitude kite, the cable interlock of two high-altitude kites, another kite descends when a high-altitude kite rises, cable and generator amature interlock, when high-altitude kite moved up and down, cable drove generator amature and rotates.

This power generating equipment back and forth moves up and down two kites and drives generator generation electric energy by controlling the flight of kites attitude, need not to consume extra energy drawing in kite back and forth, but still has the following disadvantages:

One, the cable of two kites directly is wrapped on the coaxial line wheel of installing side by side, the cable distance is too approaching, kite can collide with each other in moving process, easily damages, and the cable wrapping phenomena very easily occurs, in case be wound around, complete equipment just can't work, and needs again to go up to the air after recovery, releasing winding, causes it not have actual application value.

They are two years old, although upper wind is more stable, but its wind direction still can change, and this just requires the high-altitude kite power generating equipment will have the ability that adapts to wind vector, and the kite cable of this equipment directly is wound around on online wheel, can only adapt to the upper wind on line wheel tangent direction, in case wind direction departs from, cable just can't normally be wound around, when wind direction during perpendicular to the tangent direction of line wheel, it is particularly serious that this problem can become, and kite can't drive generator amature and rotate.

Its three, owing to wrapping phenomena very easily occurring, and the ability that adapts to wind vector a little less than, cause its power transmission efficiency low, energy transformation ratio only can maintain reduced levels, generated energy can't satisfy application request.
