[0055] Working principle of the application:

[0056] With the energy storage operation of the energy storage mechanism 2, the energy storage mechanism 2 generates a large amount of heat, the cooling liquid in the energy storage mechanism 2 is circularly pumped by the staggered pumping structure 32, so that the cooling liquid in the energy storage mechanism 2 circularly flows, and the cooling liquid is circularly pumped by the staggered pumping structure 32, so that the cooling liquid circularly flows smoothly, and before the cooling liquid flows back into the energy storage mechanism 2, it flows through the heat sink 322, the heat sink 322 cools the cooling liquid, so that the influence of the viscosity of the cooling liquid is eliminated, the circulation speed of the cooling liquid is improved, the cooling efficiency is effectively improved, the cooling effect of the energy storage battery module is enhanced, and the service life of the energy storage battery module is improved;

[0057] Wherein, when the cooling liquid is pumped staggered, the servo motor 318 is started, the servo motor 318 drives the extension arm 319 to rotate, the extension arm 319 moves left and right in the limiting ring 317 with the rotation, so as to drive the limiting ring 317 to drive the second rack 315 to move up and down on the second rail frame 314, the second rack 315 drives the gear 316 to rotate, the gear 316 drives the first rack 313 to move up and down on the first rail frame 312, so that the first rack 313 and the second rack 315 move up and down staggered, the first rack 313 drives the first piston rod 35 to move in the first straight cylinder 33, the second rack 315 drives the second piston rod 39 to move in the second straight cylinder 37, so that the first straight cylinder 33 cooperates with the first piston rod 35 to form the pumping force of the cooling liquid, the second straight cylinder 37 cooperates with the second piston rod 39 to form the pumping force of the cooling liquid, and due to the staggered reciprocating movement of the first rack 313 and the second rack 315, the first straight cylinder 33, the first piston rod 35 and the second straight cylinder 37, the second piston rod 39 form a staggered pumping;

[0058] At the same time, when the first rack 313 moves to the top end, the first trigger controller 320 is triggered, the first trigger controller 320 controls the first exhaust port stop valve 36 to open and the first suction port stop valve 34 to close, so that the cooling liquid is pumped into the first straight cylinder 33 and then into the communication pipe 311, when the first rack 313 moves to the bottom end, the second trigger controller 321 is triggered, the second trigger controller 321 controls the first exhaust port stop valve 36 to close and the first suction port stop valve 34 to open, so that the first straight cylinder 33 re-pumps the cooling liquid, so that the cooling liquid is pumped in a circulating manner;

[0059] Similarly, when the second rack 315 moves to the top end, the first trigger controller 320 is triggered, the first trigger controller 320 controls the second exhaust port stop valve 310 to open and the second suction port stop valve 38 to close, so that the cooling liquid is pumped into the second straight cylinder 37 and then into the communication pipe 311, when the second rack 315 moves to the bottom end, the second trigger controller 321 is triggered, the second trigger controller 321 controls the second exhaust port stop valve 310 to close and the second suction port stop valve 38 to open, so that the second straight cylinder 37 re-pumps the cooling liquid, so that the cooling liquid is pumped in a circulating manner, so that the cooling liquid is pumped in a relatively smooth circulating process due to the staggered pumping, and because the pumping force is completed by using air pressure, the viscosity of the cooling liquid cannot resist the pressure pumping, so that the cooling liquid cannot flow smoothly due to its own viscosity;

[0060] Then the cooling liquid is sent into the communicating pipe 311 and then passes through the radiating fin 322, the radiating fin 322 radiates heat of the cooling liquid, and the fan 323 is started to form air flow to make air enter the protective cover 31 from the air holes 324 on both sides of the protective cover 31, and the air is discharged from the air holes 324 at the bottom end of the protective cover 31 after passing through the fan 323, so that air flow is formed in the protective cover to discharge heat radiated by the radiating fin 322.

[0062] S1: With the energy storage operation of the energy storage mechanism 2, a large amount of heat is generated, and the staggered pumping structure 32 is used to pump and circulate the cooling liquid in the energy storage mechanism 2 to make the cooling liquid in the energy storage mechanism 2 flow circularly;

[0063] S2: The pumping of the cooling liquid by the staggered pumping structure 32 is circularly staggered to make the cooling liquid flow circularly smoothly;

[0064] S3: Before the cooling liquid flows back into the energy storage mechanism 2, it first flows through the radiating fin 322, and the radiating fin 322 radiates and cools the cooling liquid.
