Description

Technical Field

[0001] This utility model belongs to the field of energy storage prefabricated cabin isolation and fire prevention technology, and particularly relates to an isolation and fire prevention energy storage prefabricated cabin. Background Technology

[0002] In recent years, with the development of new energy technologies, new energy has gradually penetrated into various industries, and energy storage prefabricated cabins, as a device for energy conversion and storage, are being used more and more widely.

[0003] Currently, prefabricated energy storage modules on the market only provide fireproof isolation for the electrical and battery compartments, i.e., by installing fireproof rock wool steel structures. The battery compartment is a single, identical space, but there is no fireproof isolation between adjacent battery clusters. The corresponding fire protection layout is also based on the entire battery compartment space, which leads to the following problems: First, the lack of fireproof isolation between adjacent battery clusters poses a risk that a fire in one cluster can ignite an adjacent cluster. Second, due to the interconnectedness of the battery compartment space, perfluorohexanone (PFH) will be sprayed throughout the entire compartment after a fire, resulting in a certain degree of waste of PFH. Third, if a battery cluster in the battery compartment experiences complete thermal runaway, current prefabricated energy storage modules rely on connecting to municipal water fire suppression systems for fire extinguishing. This results in the scrapping of the entire prefabricated energy storage module even if the fire is successfully extinguished, leading to significant economic waste. Therefore, to address the risks currently present in prefabricated energy storage modules, we are providing an isolated fireproof prefabricated energy storage module that can provide fireproof isolation within the module.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-6As shown, a fireproof prefabricated energy storage compartment includes a compartment body 1. A fireproof door 2 is provided along the length of the compartment 1, corresponding to a single battery cluster, to seal the compartment 1 and ensure its functionality. A liquid cooling unit 3 is installed at one corner of the compartment 1. This unit uses liquid cooling technology to exchange heat generated by the battery clusters during operation, achieving cooling and preventing excessively high temperatures within the compartment 1 from affecting the battery clusters. For performance reasons, an electrical compartment 4 is located within the compartment 1 below the liquid-cooled unit 3. This compartment contains electrical components designed to facilitate the use of the battery pack, ensuring stability during operation. Furthermore, to enhance the fire resistance and safety of the compartment 1, a first fire-resistant isolation component 5, arranged in an L-shape, is located at the geometric center of the compartment 1. A second fire-resistant isolation component 6 is located within the compartment 1 between the liquid-cooled unit 3 and the electrical compartment 4, corresponding to the installation position of the fire door 2. The enclosure 1 is equipped with a third fireproof isolation component 7. Multiple third fireproof isolation components 7 are arranged at equal intervals and cooperate with the first fireproof isolation component 5 to form an installation space that facilitates the placement of battery clusters. Specifically, the technical solution provided in this embodiment optimizes the space area within the enclosure 1, especially achieving isolation between two adjacent battery clusters, further ensuring the safety of the energy storage battery station. On the other hand, it also reduces the risk of adjacent battery clusters being ignited, further improving safety and meeting usage requirements. In addition, to further improve the rationality of the device setup, in the space for placing battery clusters separated by the third fireproof isolation component 7 and located above the enclosure 1, fire-fighting components such as perfluorohexanone sprinklers and three-in-one detectors (i.e., temperature detectors, smoke detectors, and hydrogen detectors) water fire sprinklers are separately installed. These can serve to fire-spray the area of ​​a single battery cluster, maximizing the protection of the battery packs of other battery clusters from water flooding, and to a certain extent protecting electronic equipment and reducing risk costs.

[0023] In the aforementioned process: the various fire-resistant components ensure higher safety. Firstly, they reduce the risk of adjacent battery clusters being ignited; secondly, the fire area is isolated, further guaranteeing the safety of the energy storage power station; thirdly, due to the isolation of the fire area, fire suppression can achieve more precise fire extinguishing effects; fourthly, once fire-fighting water spraying is implemented, it can protect the remaining battery packs from water flooding to the greatest extent, thus protecting electronic equipment and reducing risk costs. This device is reasonably designed, has a simple structure, is easy to process, and has convenient installation performance, achieving isolation between adjacent individual battery clusters, improving safety performance, and effectively meeting usage requirements.

[0024] To further improve the rationality of the equipment setup, especially for fireproof isolation components designed according to different specifications and sizes of the cabin 1, to ensure their functionality, specifically: the first fireproof isolation component 5, the second fireproof isolation component 6, and the third fireproof isolation component 7 have the same specific structural composition, differing only in their size and installation location. The third fireproof isolation component 7 will be described below: the third fireproof isolation component 7 includes a fireproof structural unit 8, which includes a shell 81, and the geometric center within the shell 81... A fireproof steel plate 82 with an arc-shaped, wavy design is installed at the location. This structure can relatively increase the fireproof area to a certain extent, thereby improving its fire resistance and ensuring safety. Two fireproof steel plates 82 are installed in a mirror-image arrangement. The gap between the two fireproof steel plates 82 is filled with fireproof cotton 83. A fireproof felt 84 is installed on the outer side of the fireproof steel plate 82, adhering to the inner side of the fireproof steel plate 82. A protective pad 85 integrating waterproof and corrosion-resistant functions is installed on the outer side of the fireproof felt 84. The fireproof felt 84 serves as the first fireproof layer. It has good fireproof and heat insulation properties, which can prevent the spread of fire to a certain extent. The fireproof steel plate 82 is the second fireproof layer, which can effectively reduce the burning rate and prevent the spread of fire. The fireproof cotton 83 is the third protective layer, which has good fireproof and heat insulation properties and can play a good role in isolating adjacent battery clusters. It is highly practical. Specifically, during installation, the two fireproof steel plates 82 on the left and right are pre-connected together, and then fireproof cotton 83 is filled in the middle of their adjacent arc shapes to initially form a fireproof structural unit 8. Then, the fireproof felt 84 is placed on top of that. The fireproof steel plate 82 is attached to the structure, and then a protective pad 85 is attached to the outside of the fireproof felt 84 to improve the corrosion resistance of the fireproof structural unit 8. Finally, all the above structures are placed together in the shell 81 to complete the preparation of the fireproof structural unit 8. When installing it into the cabin 1, multiple fireproof structural units 8 are set up according to the size specifications of the cabin 1, so that they fit together to form corresponding fireproof isolation components. The operation is simple and convenient, and the functionality is strong. It can be installed and set up in a way that is compatible with different cabin 1 specifications to ensure the functionality of use.

[0025] To facilitate the connection of multiple fire-resistant structural units 8 and ensure their stability, a connecting assembly 9 is provided between the multiple fire-resistant structural units 8. The connecting assembly 9 includes a connecting sub-component 10 and a connecting female component 11. The connecting sub-component 10 includes a cylindrical receiving block 101 with a placement groove 1011 inside, which can accommodate one end of the connecting screw 113 to a certain extent. A rectangular outer cover 102 is provided on one side of the receiving block 101. The connecting female component 11 includes a cylindrical positioning block 111 with an mounting block 112 on one side. A connecting screw 113 is provided on one side of the mounting block 112 and is inserted into the placement groove 1011. The connecting screw 113 can be freely adjusted in length according to the position of the fitting groove 811, providing convenient conditions for achieving a stable connection. An installation screw 114 is provided inside the housing 81, and an adapter groove 811 is provided at the corner of the housing 81. The adapter groove 811 is also divided into two parts, one part is circular and the other part is rectangular. Specifically, when connecting two adjacent fireproof structural units 8, the connecting sub-component 10 is first placed in the adapter groove 811. Then, according to the position of the connecting sub-component 10, the position of the connecting screw 113 is adjusted so that one end can be placed in the adapter groove 811. Then, the connecting female component 11 is placed in the adapter groove 811 of another fireproof structural unit 8. During this process, the connecting screw 113 extends into the placement groove 1011, and the mounting block 112 of the connecting female component 11 can be inserted into the outer cover 102 of the connecting sub-component 10, which further improves the integrity of the connecting assembly 9, ensures the connection effect, and ensures the functionality.

[0026] To ensure the connection stability between the connecting sub-component 10 and the connecting female component 11, an insertion groove 1021 is provided on the inner side of the outer cover 102, and an insertion strip 1121 is provided on the outer side of the mounting block 112. In this embodiment, both the insertion strip 1121 and the insertion groove 1021 are rectangular. Of course, they can also be adjusted to fit, such as in a dovetail shape. The establishment of this structure can improve the fit of the connecting component 9 to a certain extent, reduce the possibility of its displacement, and provide convenience for it to complete the connection to the adjacent fireproof structural unit 8, thus meeting the usage requirements.

[0027] To further improve the rationality of the device setup, a mounting frame 12 is provided between two adjacent third fireproof isolation components 7. The mounting frame 12 includes uprights 121, and multiple concave-shaped trays 122 are arranged sequentially from top to bottom on the uprights. The uprights 121 of the mounting frame 12 are located inside the fireproof isolation components, and their upper and lower sides are connected to the upper and lower ends of the cabin 1 respectively to ensure its stability. The trays 122 set on the two uprights 121 can provide convenient conditions for the placement of the battery pack, fully ensuring its stability and ensuring the integrity of the structure.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
