A track rack 6 that meshes with the gears is provided on the inner side of the trailer track 4. Therefore, when the gears rotate, the non-load-bearing energy storage block trailer 2 will move along the direction of the trailer track 4. The hook device can connect the non-load-bearing energy storage block trailer 2 with the energy storage block, thereby driving the wheeled gravity energy storage block to move.

[0025] This embodiment is further configured such that the power device includes a first motor 10 provided on the non-load-bearing energy storage block trailer 2, the driving end of the first motor 10 is connected to the input end of the first reducer 9, and the output end of the first reducer 9 is fixedly connected to the driving gear 7.

[0026] The first motor 10 can drive the gear 7 to rotate through the reducer, thereby providing power to the non-load-bearing energy storage block trailer 2.

[0027] This embodiment is further configured such that the hook device includes a second motor 13 provided on the non-load-bearing energy storage block trailer 2, the driving end of the second motor 13 is connected to the input end of the second reducer 12, and the output end of the second reducer 12 is installed with a connecting piece, and the connecting piece is integrally formed on both sides with a pair of hooks 11 inclined upward.

[0028] The hooks 11 on both sides that are tilted upward can rotate under the drive of the second motor 13. When the driving end of the second motor 13 rotates clockwise, the hook 11 on the left side is lifted up and the hook 11 on the right side swings downward. At this time, the left hook 11 is clamped with the hanging point on the left side of the bottom of the energy storage block. At this time, the trailer can drive the energy storage block to move to the right. When the driving end of the second motor 13 rotates counterclockwise, the hook 11 on the right side is lifted up and the hook 11 on the left side swings downward. At this time, the right hook 11 is clamped with the hanging point on the right side of the bottom of the energy storage block.

At this time, the right hook 11 is clamped with the hanging point on the right side of the bottom of the wheeled gravity energy storage block 1. At this time, the non-load-bearing energy storage block trailer 2 can drive the wheeled gravity energy storage block 1 to move to the left. Conversely, when the wheeled gravity energy storage block 1 needs to move to the right, the second motor 13 drives the The moving end rotates clockwise to clamp the left hook 11 with the hanging point on the left side of the bottom of the energy storage block. After clamping, start the first motor 10 and transmit power to the driving gear through the first reducer 9. The driving gear rotates along the length direction of the track rack 6 and simultaneously drives the non-load-bearing energy storage block trailer 2 to move on the trailer track 4.
