Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Due to the long-term comprehensive effect of the surface atmosphere on the planet’s surface and solar radiation, a stable temperature gradient will be formed within a certain area that decreases with altitude. The temperature will decrease at a rate of 6.5°C / km, and the atmospheric pressure and density will also decrease approximately exponentially). The invention proposes to use the vertical temperature gradient and gravity of the planetary atmosphere system, and the buoyancy change caused by the gas-liquid phase change of the working fluid inside the floating detector to make the floating detector produce vertical oscillation motion, and the atmosphere is used as an inexhaustible source of energy. The energy bank absorbs heat from the lower part of the atmosphere and discharges heat from the upper part of the atmosphere to form an equivalent th...

Abstract

The invention discloses an aerostatic detector utilizing atmospheric temperature gradient for power generation. The aerostatic detector comprises an air bag (1), a thermal power generation system located below the air bag (1), a liquid collection ring (2), a liquid storage device (3), one-way valves (4), a heat exchanger (5), superheating pipes (6), a turbo-expander (7), a power generator (8) and an equipment load cabin (12), and the upper outer edge of the thermal power generation system is hermetically connected with the air bag (1). Equivalent thermal cycle can be formed under combined action of the atmospheric temperature gradient and vertical movement of the aerostatic detector, electric energy can be generated from energy stored in the atmosphere, and the aerostatic detector can achieve autonomous starting and navigation, and is good in safety and high in reliability.

Description

technical field [0001] The invention relates to a floating probe which uses atmospheric buoyancy to fly, in particular to a floating probe which utilizes atmospheric temperature gradient to generate thermal power. Background technique [0002] The floating probe generates buoyancy by filling a large amount of light gas (such as hydrogen, helium, etc.) in the body, so as to realize flight in the atmosphere. Floating probes such as balloons and airships have been used more than 100 years ago and have become an important means of detecting the earth's atmosphere. In addition to the earth, there are a large number of planets and satellites with atmospheres in the universe. In the solar system alone, currently known stars with relatively dense atmospheres include Venus, Mars, Jupiter, Saturn, Uranus, Neptune and other planets, as well as Saturn's largest moon Titan. Among the above-mentioned celestial bodies, except the giant planets such as Jupiter, Saturn, Uranus and Neptune,...
