Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a mechanism for converting kinetic energy generated by light aircraft such as kites or parachutes when flying at high altitudes into electrical energy. The present invention also relates to a high-altitude wind power generating device provided with the wind energy conversion mechanism. Background technique [0002] At present, wind energy has gradually developed into a major alternative energy source and has been promoted worldwide. [0003] Traditional wind power generation is greatly affected by factors such as site and wind direction, wind speed, etc., and has many shortcomings: first, wind farms are often large in scale, using ground-based wind turbines, which require a lot of land; The environment has certain negative effects; in addition, wind turbines require high tower support to enter a height of several hundred feet above the ground, and the wind at this ...

AI Technical Summary

Problems solved by technology

[0003] Traditional wind power generation is greatly affected by factors such as site, wind direction, and wind speed, and has many disadvantages: first, wind farms are often relatively large in scale, and ground wind turbines are used, which need to occupy a large amount of land; The environment has a certain negative impact; in addition, wind turbines need to be supported by high towers to enter a height of several hundred feet above the ground, and the wind at this height is relatively small and unstable, and it is difficult to align with the wind direction at any time. The actual conversion rate Low, and the manufacturing cost and construction cost of conventional wind turbines are high

[0009] First, the cables of the two kites are directly wound on the coaxial reels installed side by side. If the distance between the cables is too close, the kites will collide with each other during the movement, which is easy to be damaged, and the phenomenon of cable entanglement is very easy to occur. If it is entangled, the whole set of equipment will not work normally, and it needs to be recycled, unwound and re-launched, resulting in no practical application value

[0010] Second, although the high-altitude wind is relatively stable, its wind direction will still change, which requires the high-altitude kite power generation equipment to have the ability to adapt to changes in wind direction, and the kite cable of this equipment is directly wound on the wire wheel, which can only adapt to the wire wheel The high-altitude wind in the tangential direction, once the wind direction deviates, the cable cannot be wound normally. When the wind direction is perpendicular to the tangential direction of the wire wheel, this problem will become more serious, and the kite will not be able to drive the generator rotor to rotate

[0011] Third, due to the entanglement phenomenon and the weak ability to adapt to changes in wind direction, the power transmission efficiency is low, the energy conversion rate can only be maintained at a low level, and the power generation cannot meet the actual application requirements
