Abstract

The invention relates to a self-elevating overhead wind power generating set, and belongs to the technical field of generating equipment. The self-elevating overhead wind power generating set is composed of a self-elevating sphere wing, a self-adjusting wing, a medium frequency wind driven generator and a lead mechanism, wherein the self-elevating sphere wing provides static and dynamic elevating forces for the set, so that the unit can still remain in the air without breeze, and the height of the set in the air remains almost unchanged during the generation process; the self-adjusting wing ensures that the unit can absorb the wind energy in the air with the maximum windward side; the medium frequency generator has the advantages of small size and light weight, so that the total weight of the overhead part of the set is greatly reduced; and the electric energy is transmitted to the ground through a downlead. The wind energy in the air is far stronger than the wind energy on the ground and keeps steady in most areas, therefore, the low-power wind power generating set is free from limitation of the terrain, avoids constructing a tower, can be elevated by itself up to the air over a hundred meters, and has a better application prospect.

Description

technical field [0001] The invention relates to a self-elevating aerial wind power generation device, which belongs to the technical field of power generation equipment. Background technique [0002] Traditional wind turbines are installed on towers on the ground, and generate electricity by absorbing and converting near-surface wind energy. A large number of resource surveys have shown that in most areas of the earth's surface, the near-surface wind resources are not abundant, so it is not economically cost-effective to use wind power in these areas, thus affecting wind power generation. applications in these areas. [0003] However, in many areas where the surface wind resources are not abundant, the air wind resources are quite abundant. The actual measurement shows that in the sky of 200-1000 meters in these areas, there are generally 4-5 winds with an annual average of 6000-7000 hours and a wind energy density of 400W / m 2 Stable wind energy exists around 2000-3000 me...
