High altitude wind power and solar energy combining electric generator

Abstract

The invention relates to a highaltitude wind energy and solar energy combined generator, which is a device for generating power through utilizing rich wind and solar resources at high altitude. The combined generator comprises an air bag, a vertical shaft windmill generator, a wind shielding body, a guy rope and a photovoltaic cell, wherein the windmill generator and the photovoltaic cell are carried by the air bag into the high altitude; one side of a wind wheel of the windmill generator is provided with the wind shielding body for keeping out the wind; the wind shielding body shields vanes rotating against the wind to make the vanes not influenced by airflows, but does not shield vanes rotating before the wind to make the vanes influenced by the airflows, so that the wind wheel is rotated under the action of the airflows to generate power; and the windward side of the wind shielding body is inclined downward, can gather the airflows to the vanes of the wind wheel which are not shielded, and can obtain upward lift force at the same time. The combined generator has the advantages that the combined generator has large electrical energy, and has cheap equipment compared with the prior tower power unit and low cost distributed to each kilowatt-hour; besides, the highaltitude windmill generator can not occupy great amount of field, and has no specific requirement on surface features of the ground.

Description

Technical field: [0001] The invention discloses a wind-solar combined power generation device, in particular to a high-altitude wind power and solar power generation device, which belongs to the new energy technology. Background technique: [0002] As people pay more and more attention to clean energy, wind power technology has gradually become a hot spot. Due to technical limitations, all kinds of wind turbines currently in practical use are fixed on the ground. Generally, the power generation equipment stands tens of meters above the ground, where the wind speed is generally only 5 meters per second, and the wind direction changeable. As the altitude increases, the wind speed will increase exponentially. At a height of several thousand meters, the wind speed can not only reach about ten times that on the ground, but also the wind direction and speed are very stable. It is an ideal area for wind power generation. Solar power generation is also a hot spot of new energy tec...

Problems solved by technology

Solar power generation is also a hot spot of new energy technology. At present, photovoltaic power stations are built on the ground. Due to the influence and limitation of clouds, weather and terrain, the efficiency is relatively low, while high altitudes are not affected by these adverse factors. Sunlight Intense, ideal area for photovoltaics
