[0002] Energy storage power stations have a peak load regulation function and are also commonly used for energy storage in new energy power stations. Existing lithium battery-based energy storage power stations are mostly in the form of containers, which are placed on the ground and require a certain amount of floor space. When some batteries experience thermal runaway, a chain reaction is likely to occur, causing other batteries to experience thermal runaway accidents. And due to the characteristics of lithium batteries, it is difficult to extinguish a fire after thermal runaway, which poses certain safety hazards and may even cause casualties.

[0003] At present, the existing invention has a peak-shaving effect and is also often used for energy storage in new energy power stations. It can solve the current problem that it is difficult to extinguish a fire after thermal runaway of lithium batteries, and has broad social and economic benefits.

[0004] For example, an underground energy storage power station disclosed in the authorization announcement number CN113306444A is characterized by comprising a concrete main structure, a battery rack and a stacker; the concrete main structure is located underground, with a concrete cover plate on the upper part, and an inspection port on the concrete cover plate, which can be used to inspect and replace batteries and for personnel to enter and exit the underground energy storage power station; a battery rack and a stacker are installed inside the concrete main structure, and there are compartments on the battery rack, the compartments are multi-layered and multi-column, and the compartments can be used to place batteries, and telescopic rods are installed in the compartments, and the telescopic rods can push and pull the batteries into the compartments; the stacker is located on the side of the battery rack, including a lateral moving device and a longitudinal moving device, the lateral moving device can move horizontally along the battery rack, and the longitudinal moving device can be raised and lowered; the stacker and the telescopic rod can cooperate to complete the transfer of batteries between the inspection port and the compartment. However, for such an underground energy storage power station, it is unclear how to conveniently disassemble and install the concrete cover plate, and how to ensure the sealing between the concrete cover plate and the concrete main structure, and it is not convenient to ventilate and dissipate heat inside the concrete main structure.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is unclear how to conveniently disassemble and assemble the concrete cover plate, and how to ensure the sealing between the concrete cover plate and the concrete main structure, and it is not convenient to ventilate and dissipate heat inside the concrete main structure. Therefore, it is necessary to improve the existing technology. Utility Model Content
