[0037] The working principle of an embodiment of the present invention:

[0038] When the present invention works:

[0039] When storing energy, the surplus electric energy drives the generator-electric integrated machine 10 to rotate and consume electric energy. During the rotation of the generator-electric integrated machine 10, the bucket chain 11 is driven to continuously dig bulk materials from a low place and lift them to a high place, and the bulk materials are transported to the parallel scraper conveyor 12 through the discharge port 14 at the high place. The parallel scraper conveyor 12 and the energy storage scraper conveyor 15 are arranged perpendicular to each other. The parallel scraper conveyor 12 transfers the bulk materials to the energy storage scraper conveyor 15, and the energy storage scraper conveyor 15 transports the bulk materials to the storage bin 6 at the rear to complete the energy storage; the storage bin 6 is a structure that is wide at the top and narrow at the bottom. The bulk materials can enter the energy storage bin from the top and can flow out of the energy storage bin from the discharge hole at the bottom. The opening or closing of the discharge hole can be achieved by remotely controlling the electric gate 18 through the control system;

[0040] Energy is released, the energy storage scraper conveyor 15 stops working, the discharge hole of the storage bin 6 opens, and the bulk material flows out and falls into the energy release scraper conveyor 13, which transports the bulk material to the hopper chain 11 at the front end. The hopper chain 11 is driven by the gravity of the bulk material to rotate in the opposite direction, and at the same time drives the power generation and electric integrated machine 10 to rotate and generate electricity, thereby realizing the conversion of the potential energy of the bulk material into electrical energy.
