Description

A kind of wind energy conversion 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 lightweight aircraft such as kite or levitating parachute produced when high-altitude flight.The invention still further relates to the overhead wind power generator being provided with described wind energy conversion mechanism.

Background technique

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

Traditional wind-power electricity generation affects comparatively large by the factor such as place and wind direction and wind velocity, there is 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 to support the height that just can enter apart from ground hundreds of foot, and the wind-force of this height is less, simultaneously also unstable, be difficult to aim at wind direction at any time, actual conversion is lower, and the manufacture cost of general wind power generation machine, construction cost are all very high.

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

Wherein, first kind of way needs the equipment such as generator, cable to be stabilized in high-altitude, because weight is larger, therefore go up to the air limited height, energy transformation ratio is low, and cost is high, reclaim difficulty, there is the risk of falling, and the second way does not exist above shortcoming, become the main R&D direction utilizing high altitude wind energy gradually.

Publication number is the application for a patent for invention Publication Specification of CN101240778A, disclose a kind of kite power generation method, its working principle is the Effector that kite passes through on the ground, change Windward angle, when kite surface is perpendicular to air-flow, kite produces maximum pull because of wind resistance, kite passes through rope, drawing generator generates electricity, between flyback return period, kite Effector changes kite Windward angle, resistance is minimum close to being parallel to air-flow to make its kite surface, generator switches to motor, energy is provided by outside, kite is pulled to return by rope, realizing interruption utilizes high altitude stream to generate electricity, 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.

This power generating equipment, by controlling flight of kites attitude, making two kites drive electrical generators that back and forth moves up and down produce electric energy, without the need to consuming extra energy drawing in kite back and forth, but still having the following disadvantages:

One, the cable of two kites is directly wrapped in the line coaxially installed side by side and takes turns, cable distance is too close, kite can collide with each other in moving process, easily damages, and very easily occurs cable winds phenomenon, once be wound around, complete equipment just cannot normally work, and again goes up to the air, cause it not have actual application value after needing recovery, releasing winding.

They are two years old, although upper wind is more stable, but its wind direction still can change, this just requires that high-altitude kite power generating equipment will have the ability adapting to wind vector, and the kite cable of this equipment is directly wound around on online wheel, the upper wind in line wheel tangent direction can only be adapted to, once wind direction departs from, cable just cannot normally be wound around, when the tangent direction that wind direction is taken turns perpendicular to line, this problem can become particularly serious, and kite cannot drive electrical generators rotor turns.

Its three, owing to very easily there is wrapping phenomena, and it is more weak to adapt to the ability of wind vector, and cause its power transmission efficiency low, energy transformation ratio only can maintain reduced levels, and generated energy cannot meet application request.
