[0038] The working principle of an embodiment of the present invention:

[0039] When the present invention works:

[0040] During energy storage, the RGV trolley 13 in the bottom cargo area 5 carries the gravity block and travels along the transport track 14, the generator-electric integrated machine 11 drives the drum 16 to rotate, and the car 18 descends accordingly. When the car 18 descends to the transport track 14, the telescopic plate 19 extends, and the RGV trolley 13 enters the car 18 along the telescopic plate 19. The telescopic plate 19 retracts at the same time as the RGV trolley 13 enters the car 18. After the RGV trolley 13 completely enters the car 18, the RGV trolley 13 stops moving. At this time, the generator-electric integrated machine 11 drives the drum 16 to rotate, and the car 18 rises accordingly, lifting the RGV trolley 13. When it is lifted to the transport track 14 of the top cargo area 4, the telescopic plate 19 extends, and the RGV trolley 13 travels along the telescopic plate 19 to leave the car 18, and continues to travel along the transport track 14 of the top cargo area 4 to complete energy storage;

[0041] When releasing energy, the RGV trolley 13 in the top cargo handling area 4 carries the gravity block and moves along the transport track 14. The car 18 is flush with the transport track 14, and the telescopic plate 19 is extended. The RGV trolley 13 enters the car 18 along the telescopic plate 19. The telescopic plate 19 retracts at the same time as the RGV trolley 13 enters the car 18. After the RGV trolley 13 completely enters the car 18, the RGV trolley 13 stops moving. Under the action of gravity, the car 18 starts to descend and the driving drum 16 rotates to drive the generator-electric integrated machine 11 to generate electricity. When it descends to the transport track 14 of the bottom cargo handling area 5, the telescopic plate 19 is extended, and the RGV trolley 13 moves along the telescopic plate 19 to leave the car 18 and continue to travel along the transport track 14 of the bottom cargo handling area 5. The energy release is completed, and the electric energy generated by the generator-electric integrated machine 11 is transmitted to the supercapacitor 12;

[0042] After the supercapacitor 12 is fully charged, the excess electric energy is stored by the heat storage device 22 and the cold storage device 23 , and the heat storage device 22 and the cold storage device 23 are complemented by the heat exchanger 24 .
