Description
Technical Field
[0001] The utility model relates to an energy storage prefabricated cabin, in particular to an energy storage prefabricated cabin made of concrete, belonging to the technical field of energy storage systems. Background Art
[0002] In the prior art, traditional containers are generally used as battery cabins and PCS electrical cabins in energy storage systems. The outer shell is generally designed as a structural member mainly composed of metal sheet metal, thermal insulation rock wool, etc., which has defects such as low fire resistance rating, short fire resistance time, and low strength. After the battery thermal runaway combustion, it is extremely easy to burn through and collapse.
[0003] Under normal circumstances, after a certain fire protection design for concrete structure buildings, even if a fire occurs, due to the structural characteristics of the solidified substances inside, the molten concrete still has strong pressure-bearing capacity for the fire resistance performance of the concrete structure. Therefore, the concrete structure has better fire resistance performance than the metal structure and thus higher safety.
[0004] On the other hand, the metal container prefabricated cabin is a horizontal structure, and the energy storage battery packs are horizontally arrayed in the container. Due to the low fire protection and fire prevention level, it cannot meet the specified fire protection level, and a certain fire prevention distance needs to be left between the battery cabins during on-site layout, resulting in a large floor area. Summary of the Utility Model
[0005] The concrete energy storage prefabricated cabin proposed by the utility model aims to overcome the above deficiencies existing in the prior art, replace the metal container prefabricated cabin, improve the fire protection and fire prevention performance, and reduce the floor area.
[0006] The technical solution of the utility model: A concrete energy storage prefabricated cabin, the structure of which includes a concrete energy storage prefabricated cabin unit. The concrete energy storage prefabricated cabin unit includes a concrete energy storage prefabricated cabin body, a concrete fire door, and energy storage battery packs. The concrete energy storage prefabricated cabin body is a rectangular box structure integrally cast with reinforced concrete and having an opening at the front. A concrete fire door is provided at the opening of the front of the concrete energy storage prefabricated cabin body, and several layers of energy storage battery packs are evenly spaced and placed in the concrete energy storage prefabricated cabin body from top to bottom. By utilizing the characteristics of strong bearing capacity, integral molding, and high fire resistance rating of reinforced concrete, the metal container prefabricated cabin with a horizontal structure in the prior art is changed into a reinforced concrete prefabricated cabin structure that can be vertically arranged, which can fundamentally solve the problems of large floor area occupied by lithium battery energy storage, poor fire protection, and fire prevention partition.
[0007] Preferably, the concrete energy storage prefabricated cabin unit further includes a concrete fire partition wall, and concrete fire partition walls extending in opposite directions are respectively provided on the front, back, and top surfaces of the concrete energy storage prefabricated cabin body. It can meet the requirements of fire protection and fire prevention partition.
[0008] Preferably, concrete pouring points are reserved at the four corners of the concrete energy storage prefabricated cabin body, and the concrete energy storage prefabricated cabin body is connected to the concrete fire partition wall through the concrete pouring points by casting.
[0009] Preferably, the sides of multiple adjacent concrete energy storage prefabricated cabin units are arranged in close contact. Realize left - right splicing, which can further reduce the floor area.
[0010] Preferably, multiple concrete energy storage prefabricated cabin units are stacked, and the bottom of the upper concrete energy storage prefabricated cabin unit is placed on the concrete fire partition wall at the top of the lower concrete energy storage prefabricated cabin unit. Realize up - down splicing, which can further reduce the floor area.
[0011] Advantages of the present utility model: The structure is reasonably designed, transforming the existing lithium - battery energy storage steel structure into a concrete structure, which can effectively improve the fire resistance rating, effectively solve the problem that the lithium - battery energy storage steel structure cannot meet the specified fire protection rating due to its low fire - fighting and fire - prevention level. Adjacent cabins can be closely arranged without leaving a certain fire - prevention distance like the steel structure, and they can also be stacked, effectively reducing the floor area of lithium - battery energy storage.
