Embodiment Construction

[0036] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0037] like figure 1 As shown, the invention discloses a rotary hammer type lunar surface energy collection device, which includes a fixed wheel, a rotating wheel, a Stirling engine, a solar heat collection module and an energy storage module.

[0038] 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.

[0039] like figure 2 As shown, several piezoelectric generating units are arranged on the fixed wheels.

[0040] like Figure 4 As shown, the piezoelectric generating unit includes a straight rod and an additional mass block; the two ends of the straight rod are respectively fixed end and impact end, and piezoelectric ce...

Abstract

The invention discloses a rotary hammering-type moon-surface piezoelectric power generation device and a work mode thereof. The piezoelectric power generation device comprises a Stirling engine, a rotating wheel, a fixing wheel, a solar heat collection module and an energy storage module. The fixing wheel is provided with a piezoelectric power generation unit. The rotating wheel is provided with a driving hammer. A cold end of the Stirling engine is arranged in moon-surface soil and a hot end is arranged on a moon surface. During working, a temperature difference of an upper portion and a lower portion of the moon surface is used to compress and expand an inert gas arranged in the cold and hot ends so as to drive the Stirling engine to drive the rotating wheel to rotate. The driving hammer on the rotating wheel knocks the piezoelectric ceramic power generation unit on the fixing wheel so that a piezoelectric ceramic sheet generates deformation and charges are generated and stored through the energy storage module. In the invention, a temperature difference on a moon is used to realize piezoelectric power generation, the structure is simple, work efficiency is high and the device can collect energy in an all-weather mode.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a rotary hammer type lunar surface energy collection device and its working method. 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 less impact...
