[0044] The working principle of an embodiment of the present invention:

[0045] When the present invention works:

[0046] When the system is storing energy: the gravity block 7 in the cave 4 moves along the bottom horizontal conveyor 8 toward the shaft, and at the same time, the movable door 22 of the car 14 is unfolded. When the gravity block 7 moves to the end of the bottom horizontal conveyor 8, the movable door 22 is unfolded and flush with the bottom horizontal conveyor 8. The gravity block 7 moves from the bottom horizontal conveyor 8 to the B conveyor 24 on the movable door 22. The gravity block 7 continues to move along the B conveyor 24. The gravity block 7 moves all the way to the A conveyor 23. At this time, the loading of the gravity block 7 is completed, and at the same time, the movable door 22 of the car 14 is retracted upward, and the electric The power generator 12 drives the winch 13 to lift the car 14 upward along the power supply track of the shaft 3. When it is lifted to the shaft opening of the shaft 3, the movable door 22 of the car 14 is unfolded. After the movable door 22 is unfolded, it is flush with the top horizontal conveyor 6. The gravity block 7 moves along the A conveyor 23 and the B conveyor 24 in sequence. When the gravity block 7 moves to the end of the A conveyor 23, the gravity block 7 moves from the A conveyor 23 to the top horizontal conveyor 6. The gravity block 7 continues to move along the top horizontal conveyor 6, completing the storage of the gravity potential energy of the gravity block 7 in the top yard 2.

[0047] When the system releases energy: the gravity block 7 on the top horizontal conveyor 6 moves toward the shaft, and at the same time, the movable door 22 of the car 14 is unfolded. When the gravity block 7 moves to the end of the top horizontal conveyor 6, the movable door 22 is unfolded and flush with the top horizontal conveyor 6. The gravity block 7 moves from the top horizontal conveyor 6 to the B conveyor 24 on the movable door 22. The gravity block 7 continues to move along the B conveyor 24. The gravity block 7 moves all the way to the A conveyor 23. At this time, the loading of the gravity block 7 is completed. At the same time, the movable door 22 of the car 14 is retracted upward. Under the action of gravity, when the car 14 descends, The steel cable 15 drives the drum of the winch 13 to rotate, and the rotating shaft of the winch 13 drives the electric generator 12 to generate electricity, and the electricity is transmitted to the energy storage device 10.
