Device for cooperative storage with thermoelectric coupling and for staged energy conversion with multiple media in the deep subsurface

Abstract

A device for cooperative energy storage with thermoelectric coupling and for staged energy conversion with multiple media in deep underground, comprising an energy storage reaction chamber, characterized in that a medium reservoir and metering container is permanently connected to the right side of the top of the energy storage reaction chamber; a grinding chamber is permanently attached to the upper side of the inner wall of the medium reservoir and metering container; a grinding ball is arranged inside the grinding chamber; an outlet opening is permanently formed on the underside of the grinding chamber; a main drive shaft is rotatably mounted on the upper side of the inner wall of the medium reservoir and metering container; a limiting sliding strip is permanently attached to each of the four sides of the shaft of the main drive shaft; a circular opening is provided on the top of the grinding ball;the inner wall of the circular opening is slidably connected to the shaft of the main drive shaft; a limiting sliding groove is formed on each of the four sides of the inner wall of the circular opening, which interacts positively with the limiting sliding strips.
