Condenser for space solar energy power station

Abstract

This invention discloses a condenser for a space solar energy power station which comprises an annular inflatable air bag made of flexible materials. A light-reflecting thin film made of flexible materials is fixed on the annular surface of the annular inflatable air bag; a support rod made of rigid materials passes through the center of the light-reflecting thin film and is fixed with the light-reflecting thin film; the focus where the support rod is positioned on the light-reflecting thin film surface is provided with a photovoltaic member; the annular inflatable air bag is connected to the support rod through pulling ropes; the lengths of the pulling ropes can be adjusted to enable the light-reflecting thin film to form a cone-shaped reflection surface and the apex angle of the cone-shaped reflection surface can be adjusted; the cone-shaped reflection surface is plated with a light-reflecting layer; and when the annular air bag is in an inflating state, the light-reflecting thin film which is in a foldable state is expanded. The condenser for the space solar energy power station is characterized in that the ratio of the expanding area to the folding volume is high, which is beneficial for rocket emission, and an oversized condensation solar reflector is obtained. The condenser for the space solar energy power station is applicable to the space solar energy power station and the earth solar energy power station.

Description

technical field

[0001] The invention belongs to the field of solar power generation, and relates to a foldable super-large concentrating mirror prepared by using an air pressure memory element, and more particularly to a concentrating mirror for space solar power stations. Background technique

[0002] The idea of ​​building solar power plants in space has been proposed as early as 1968, but it is only recently that humans have started to really put it into action. Japan is one of the pioneers of this project, which is expected to cost US$21 billion and generate one gigawatt of electricity for 294,000 households.

[0003] The intensity of sunlight in space is 5-10 times greater than that on the ground. Solar power technology can provide constant and non-polluting energy, which is very different from the intermittent and cloud-covered solar energy on the ground, and it does not emit pollutants like fuel power plants, nor does it emit pollutants like nuclear power plants Gen...
