Abstract

The invention relates to power generation method and device based on the principle of expansion caused by heat and contraction caused by cold of a solid material. When ambient temperature is increased, the elastic potential energy of a solid material is accumulated, when the ambient temperature is reduced, the solid material is restored and keeps the elastic potential energy. When the temperature changes once, the elastic potential energy is accumulated once, when the potential energy is accumulated to an extent, the elastic potential energy is controlled to release by an internal device, so as to drive a generator to generate electric energy and store electric energy. The one-time accumulated energy quantity mainly determines the elastic coefficient of a spring, and the speed of energy accumulation depends on the expansion and contraction coefficient of the material and the fulcrum position of a lever. Therefore, the considerable energy accumulation quantity can be obtained in a shorter time by using the spring with high coefficient of elasticity and a material with high expansion and contraction coefficient, and adjusting the fulcrum appropriately.

Description

technical field [0001] The technical proposal belongs to the technical field of power generation, and specifically relates to a power generation method and device using the principle of thermal expansion and cold contraction for aerospace engineering power supply. Background technique [0002] In some aerospace projects, such as moon landing or Mars exploration, most of the solar energy is directly used at present. Direct use of solar energy requires solar panels, which have a large area and poor invulnerability (for example, the maximum wind force on Mars is equivalent to a 54-level typhoon). At the same time, the temperature range of the day and night environment involved in aerospace engineering is extremely large (hundreds of degrees Celsius, for example, the temperature difference between day and night on the moon can reach more than 300 degrees Celsius; the temperature difference between day and night on Mars can reach about 100 degrees Celsius). Contents of the inve...
