摘要

The device has a closed, gas-impermeable, inductile, light outer cover (1), solar canvas (4), pump (6) and windmill (7). A space in the outer cover is divided into three parts by two flexible partition walls (2, 3) and is filled with airy gas between the partition walls. Atmosphere gas is pumped and exhausted alternatively between the partition wall (2) and the cover and between the partition wall (3) and the cover.
