Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a prefabricated firewall system for energy storage substations. Background Technology

[0002] Driven by technological innovation and continuous cost reduction, China's electrochemical energy storage market has maintained rapid development, with its application scale continuously expanding. Fire prevention has become the most important aspect of safety for electrochemical energy storage stations. Strict requirements govern the fire safety distance between outdoor battery compartments of electrochemical energy storage stations. In areas with limited land, installing firewalls can not only reduce the fire safety distance between battery compartments but also effectively ensure fire safety.

[0003] Currently, there are generally two layout schemes for battery compartments. One is a layout that does not require firewalls, with the spacing between battery compartments arranged to meet relevant specifications. However, the disadvantage is that the spacing between battery compartments is relatively large, resulting in a larger land area required for the electrochemical energy storage station.

[0004] Another approach is to install firewalls equidistant from the battery compartments on either side. Because of these firewalls, the distance between the battery compartments can be reduced while still meeting relevant regulations, saving land area for the electrochemical energy storage station. However, this reduced spacing, coupled with the need for firewalls, means that the foundation construction of the firewalls can interfere with the construction and installation of the battery compartments and external pipelines. Furthermore, improperly placed firewalls can result in insufficient space for battery compartment inspection and maintenance, preventing access for inspection and maintenance equipment.

[0005] Therefore, there is an urgent need to propose an energy storage substation that has a small footprint, high space utilization, and ample internal activity space. Utility Model Content

[0006] In view of the above problems, this utility model provides a prefabricated firewall system for energy storage substations.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0008] A prefabricated firewall system for energy storage substations is provided, comprising multiple rows of parallel battery compartments, each row of battery compartments including an integrated inverter compartment and at least two battery compartments, with maintenance and inspection passages provided between adjacent rows of battery compartments.

[0009] It also includes a first firewall and a second firewall. The first firewall is set between two adjacent battery compartments in each row of battery compartments, and the second firewall is set between two adjacent rows of battery compartments. The second firewall is located on one side of the maintenance passage and is attached to the battery compartment on either side.

[0010] Furthermore, it also includes a battery compartment foundation installed underground and corresponding to each battery compartment. The second firewall is integrally formed with the battery compartment foundation below the adjacent battery compartment and is located on one side edge of the top wall of the battery compartment foundation.

[0011] Furthermore, the door of the battery compartment, which is attached to the second firewall, faces away from the firewall on the basis of the battery compartment.

[0012] Furthermore, the battery compartment foundation and the second firewall are made of precast concrete blocks, and the battery compartment foundation is provided with mounting slots and mounting holes for the installation and passage of pipelines on the battery compartment.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By rationally arranging and installing the battery compartment and firewall in the energy storage substation, the land area of ​​the energy storage substation can be reduced. Under the premise of meeting the reasonable fire protection distance of the battery compartment, maintenance and repair passages are reserved, which can allow maintenance and repair equipment to enter and exit the energy storage substation and carry out maintenance and repair of the battery compartment, thus saving land and making the layout reasonable.

[0015] 2. By pre-casting the battery compartment foundation and the second firewall as a single unit, and pre-processing the installation grooves and holes on the battery compartment foundation for the installation of battery compartment pipelines, the battery compartment foundation is buried underground during the construction of the energy storage substation. After assembling the battery compartment foundation, the battery compartment is then hoisted and installed on the battery compartment foundation. This unifies the installation and routing of pipelines, improves the installation efficiency of the battery compartment, and makes the wiring inside the energy storage substation neat and reduces interference.

[0017] Figure 2 This is a schematic diagram of the battery compartment installation structure according to an embodiment of this application.

[0018] The components include: 1. Battery compartment; 11. Inverter integrated compartment; 12. Battery compartment; 121. Main gate; 2. Inspection and maintenance passage; 3. First firewall; 4. Second firewall; 5. Battery compartment foundation. Detailed Implementation

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a prefabricated firewall system for energy storage substations, referring to... Figure 1 and Figure 2The system includes multiple rows of battery compartments arranged side-by-side. Each row of battery compartments 1 includes one integrated inverter compartment 11 and at least two battery compartments 12. The integrated inverter compartment 11 and battery compartments 12 are arranged sequentially, with the integrated inverter compartment 11 located on one side of the battery compartment 12. A maintenance passage 2 is provided between adjacent rows of battery compartments 1. The prefabricated firewall system also includes a first firewall 3 and a second firewall 4. The first firewall 3 is located between two adjacent battery compartments 12 in each row of battery compartments 1, and does not extend into the maintenance passage 2 to obstruct passage. The second firewall 4 is located on one side of the maintenance passage 2 and is flush with any one of the battery compartments 12. The second firewall 4 is parallel to the maintenance passage 2.

[0021] Through the above design, the firewalls used to separate adjacent battery compartments 12 in the energy storage substation can reduce the footprint of the energy storage substation while maintaining the fire protection distance of the full energy storage substation. At the same time, it provides maintenance access 2, providing sufficient space for the maintenance and repair of battery compartment 12.

[0022] Furthermore, it also includes battery compartment foundations 5 buried underground, each corresponding to one of the battery compartments 12. The second firewall 4 is integrally formed with the battery compartment foundation 5 below the adjacent battery compartment 12, and the second firewall 4 is located on one edge of the top wall of the battery compartment foundation 5. By integrating the second firewall 4 with the battery compartment foundation 5, the structural stability of the second firewall 4 can be improved.

[0023] In this embodiment, both the battery compartment foundation 5 and the second firewall 4 are precast concrete blocks. The resulting precast blocks can be directly hoisted onto the site for installation, improving the construction efficiency of the energy storage substation. Installation slots and holes for the installation and passage of pipelines on the battery compartment 12 are prefabricated on the battery compartment foundation 5. After the battery compartment foundation 5 is constructed, the battery compartment 12 can be directly hoisted and placed on it, achieving rapid installation of the battery compartment 12 while meeting fire safety distance requirements, thus improving installation efficiency. The standardized factory-processed installation slots and holes on each block standardize the pipeline installation locations and procedures for the battery compartment 12, reducing construction and installation interference.

[0024] The battery compartment 12, which is attached to the second firewall 4, has its door 121 for operation and maintenance located on the side of the battery compartment 12 away from the second firewall 4. This allows maintenance personnel to transport maintenance equipment and perform maintenance on the battery compartment 12 while passing through the maintenance passage 2. This arrangement of the firewall and the battery compartment 12 solves the problem of insufficient space for maintenance and repair in the battery compartment 12.
