Embodiment Construction

[0041] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0042] Such as figure 1 As shown, the present invention discloses a rotating and colliding lunar surface piezoelectric energy harvesting device, which includes a fixed wheel, a rotating wheel, a Stirling engine, a solar heat collection module and an energy storage module.

[0043] The fixed wheel is in the shape of a circle and is fixed on the moon. The center of the rotating wheel is fixed on the center of the fixed wheel by a bearing, so that the rotating wheel and the fixed wheel are concentric and in the same plane, and the rotating wheel can rotate.

[0044] Such as figure 2 and image 3 As shown, several piezoelectric generating units are arranged on the fixed wheel and the rotating wheel.

[0045] Such as Figure 4 As shown, the piezoelectric generating unit includes a straight rod and an additional mass block; the two ends of the strai...

Abstract

The invention discloses a rotating collision-type lunar piezoelectric energy collection device and a working method thereof. The piezoelectric energy collection device comprises a stirling engine, a rotating wheel, a fixed wheel and an energy storage module, wherein the fixed wheel and the rotating wheel are provided with piezoelectric power generation units respectively; a cold end of the stirling engine is arranged in lunar soil; and a hot end is arranged on the lunar surface. When the rotating collision-type lunar piezoelectric energy collection device works, an inert gas arranged in the cold end and the hot end is compressed and expanded by a temperature difference between upper part and the lower part of the lunar surface, so that the stirling engine is driven and the rotating wheel is driven to continuously rotate along the counter-clockwise direction (clockwise direction); the piezoelectric power generation units collide with one another along with rotation of the rotating wheel, so that piezoelectric ceramic is bent and deformed to generate charges on the surface; and the charges are collected into the energy storage module for achieving power generation. The piezoelectric power generation is achieved by the temperature difference on the moon; the structure is simple; the work efficiency is high; and the energy can be collected in an all-weather manner.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a rotating and colliding lunar surface energy collection device and a working method thereof. Background technique [0002] As an important part of the development of space science, interstellar exploration has always been highly valued and invested heavily by countries all over the world. Any machine activity or human activity on an alien planet is inseparable from energy sources. As far as the moon is concerned, the most convenient and most directly available energy source is solar energy. Due to the poor thermal conductivity of the lunar soil, the temperature difference between the lunar surface and the lunar soil is caused. In particular, there is a large temperature gradient in the lunar soil in the depth direction. The deeper the lunar soil, the smaller the temperature difference between day and night, and the temperature difference is affected by latitude. has l...
