Description

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

Technical field

The present invention relates to wind energy power technology field, be converted to the mechanism of electric energy especially for the kinetic energy that the lightweight aircraft such as kite or levitating parachute is produced when the high-altitude flight.The invention still further 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 factor such as place and wind direction and wind velocity, has shortcomings: first, wind power plant often scale is larger, employing be 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 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.

Compared with surface wind, upper wind wind-force is stronger, 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 power station aloft, in 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 high-altitude by the equipment such as generator, cable, 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 the second way does not exist above shortcoming, become 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 CN 101240778A, 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 kite surface is during perpendicular to air-flow, kite produces maximum pull because of wind resistance, kite passes through rope, drawing generator generating, between flyback return period, kite Effector changes kite Windward angle, its kite surface is approached and be parallel to air-flow and resistance minimum, generator switches to motor, provide energy by outside, pull kite to return by rope, realize being interrupted and utilize high altitude stream generating, its deficiency is just, this method can only produce electric energy at kite ascent stage, and need to consume extra energy drawing in kite back and forth, therefore wind energy transformation rate is low.

Notice of authorization number is that the utility model patent of CN 201714574U discloses a kind of high-efficiency high-altitude kite electric generator, formed by a pair of high-altitude kite, generator set, high-altitude kite is pulled by cable, when work in upper-middle troposphere, flight attitude controlling device is installed on high-altitude kite, the control signal that can receive ground regulates the angle windward of high-altitude kite, the cable interlock of two high-altitude kites, in the time that a high-altitude kite rises, another kite declines, cable and generator amature interlock, when high-altitude kite moves up and down, cable drives generator amature to rotate.

This power generating equipment, by controlling flight of kites attitude, back and forth moves up and down two kites and drives generator to produce electric energy, without consuming extra energy drawing in kite back and forth, but still has the following disadvantages:

One, the cable of two kites is directly wrapped on the coaxial line wheel of installing side by side, cable distance is too approaching, kite can collide with each other in moving process, easily damages, and very easily occurs cable wrapping phenomena, once be wound around, complete equipment just cannot normally be worked, and needs recovery, releasing lift-off again after being wound around, and 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, this just requires high-altitude kite power generating equipment will have the ability that adapts to wind vector, and the kite cable of this equipment is directly wound around on online wheel, can only adapt to the upper wind in line wheel tangent direction, once wind direction departs from, cable just cannot normally be wound around, when wind direction is during perpendicular to the tangent direction of line wheel, it is particularly serious that this problem can become, and kite cannot drive generator amature to rotate.
