Description

Technical Field

[0001] This utility model relates to fire protection equipment in the energy storage area of ​​a substation, and particularly to a fire valve wall device for an energy storage substation. Background Technology

[0002] The energy storage area of ​​a substation is a dedicated area integrating battery packs (such as lithium-ion batteries), battery management systems (BMS), energy storage converters (PCS), and fire protection facilities. It often adopts a containerized modular design to support rapid deployment. Its core functions include grid peak shaving (mitigating load fluctuations and improving stability), energy optimization (reducing wind and solar curtailment and lowering grid investment costs), and emergency power supply (providing backup power support during faults). Because it is an integrated battery pack, thermal runaway could lead to an explosion (such as hydrogen release), therefore national standards mandate the installation of multi-level fire protection facilities.

[0003] Traditional fire valve well 01 (such as Figure 1 and Figure 2 As shown, the fire-fighting pipeline 3 and control valve 4 are installed underground within valve well 01 and connected by four-way connectors between them. In actual fire emergency operations, the process is cumbersome, requiring the valve well 01 cover to be opened sequentially, the target valve located, and the control valve 4 manually opened and closed. This process is time-consuming and relies heavily on personnel experience, delaying the crucial fire-fighting window. Furthermore, operators must operate the control valve 4 near the fire source in a high-temperature environment, posing a high risk of exposure to deflagration and toxic fumes. Large energy storage power stations also require the simultaneous control of multiple valves, making coordination difficult and prone to misoperation or omissions. However, the existing valve well 01 is prone to dust and corrosion due to its long-term sealed design, requiring frequent opening for maintenance, resulting in high labor and equipment costs. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides a fire valve wall device for energy storage power stations, enabling modular control of multiple valves, shortening the operation path, creating a safe operation zone, achieving "zero exposure" fire suppression, avoiding the risk of personnel casualties, reducing construction costs, and providing a new fire protection paradigm of "centralized control + physical isolation".

[0005] The purpose of this utility model is achieved as follows: A fire valve wall device for an energy storage power station, comprising a plain concrete foundation buried underground, and a single-layer wall on top of the plain concrete foundation; the inner and outer surfaces of the single-layer wall are provided with fireproof rock wool layers, and high-temperature resistant windows are provided on the inner and outer sides in the middle position; control valves are installed around the outer side of the high-temperature resistant windows, the inlets of the control valves are connected to fire hydrants through fire hoses, and the control valves are all connected to the fire water inlets of the energy storage battery compartment through the fire pipe outlets on the inner side of the single-layer wall.

[0006] Furthermore, each of the control valves is equipped with a color-coded number, which corresponds to the code of the energy storage battery compartment in the energy storage area.

[0007] Furthermore, the control valve is equipped with a rotary wrench and a spring-assisted device.

[0008] Furthermore, all the control valves are connected to the main control valve on the outer side of the valve wall via pipes, and the inlet of the main control valve is connected to a fire hydrant.

[0009] This utility model integrates multiple fire-fighting water valves into a wall panel, achieving "one wall controlling multiple channels" and shortening the operation path. It enables "zero-exposure" operation for personnel; through the wall's isolation, operators completely avoid the risk of battery compartment explosion, and can complete all operations from a safe area on the front of the wall. The control valves on the valve wall can be directly connected to outdoor fire hydrants via fire hoses, requiring only "one-to-one connection and opening" in case of fire, eliminating the need for step-by-step operations. The elimination of decentralized valve wells, replaced by exposed integrated wall panels, reduces civil engineering work and shortens the construction period. Furthermore, routine inspections no longer require opening manhole covers, improving troubleshooting efficiency. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. See also Figures 3 to 5A fire valve wall device for an energy storage power station is disclosed. The valve wall 1 includes a plain concrete foundation 11 buried underground. A single-layer wall 12 is provided on the plain concrete foundation 11. The inner and outer surfaces of the single-layer wall 12 are covered with fireproof rock wool layers 13, and high-temperature resistant viewing windows 2 are provided on the inner and outer sides in the middle position. Control valves 4 are installed around the outer side of the high-temperature resistant viewing windows 2. The control valves 4 are equipped with a rotating wrench and a spring-assisted device. The inlet of the control valves 4 is connected to a fire hydrant through a fire hose. The control valves 4 are each equipped with a different colored digital code, which corresponds to the code of the energy storage battery compartment in the corresponding energy storage area. The control valves 4 are connected to a fire pipe 3 on the inner side of the single-layer wall 12, and the end of the fire pipe 3 is connected to the fire water inlet of the energy storage battery compartment.

[0019] Another embodiment of this utility model is that all control valves 4 are connected to the main control valve 5 on the outer side of the valve wall 1 through pipes, and the inlet of the main control valve 5 is connected to the fire hydrant.

[0020] Example 1: A photovoltaic project integrating agriculture and solar power utilizes the technology of this utility model to meet the requirements of "centralized control + physical isolation," while simultaneously shortening the construction period and replacing the traditional fire valve well scheme 01. Valve wall 1 is a single-layer wall 12, with a 240mm thick autoclaved lime-sand brick inner wall and an outer fireproof rock wool layer 13 (fire resistance rating ≥ 2 hours). The plain concrete foundation 11 is a 300mm thick strip foundation. The dimensions of a single valve wall 1 are: 2.4m (length) × 2.5m (height) × 0.25m (thickness), covering four battery compartments; each compartment corresponds to a control valve 4, which adopts a manual quick-opening design (opening and closing time ≤ 15 seconds), with its operation interface concentrated in the safe area on the front of the wall. Rubber sealing rings are added to the flange interface of control valve 4 to prevent rainwater infiltration or insect entry; the valve handle has an anti-rust coating to adapt to the humid outdoor environment.

[0021] After the fire is confirmed, the operator opens the control valve 4 of the corresponding compartment on the back of the wall; then, the outdoor fire hydrant outlet is connected to the quick-connect flange of the fire pipeline 3 using a fire hose, and the outdoor fire hydrant valve is opened to supply water; thus achieving the purpose of extinguishing the fire in the energy storage battery compartment; the operator can confirm the progress of the fire extinguishing through the observation port 2 on the front of the valve wall 1.

[0022] Example 2: All control valves 4 are connected to the main control valve 5 on the outer side of valve wall 1 via pipes. The inlet of the main control valve 5 is connected to a fire hydrant. When a fire occurs in a compartment, the fire hydrant is connected to the inlet of the main control valve 5 via a fire hose, the main control valve 5 is opened, and the control valve 4 corresponding to the compartment number is opened to supply water to the fire inlet of the energy storage battery compartment. The operator can check the progress of fire extinguishing through the high-temperature resistant viewing window 2 on the front of valve wall 1. Everything else is the same as in Example 1.

[0023] This utility model embodies the advantages of centralized control. A single valve wall 1 can control four energy storage power station compartments, while also supporting lateral expansion (extending the wall by 0.6m for every two additional compartments). The operating radius is reduced from the traditional 100 meters (distributed wells) to 5-10 meters. Personnel are located in the safety zone opposite to the fire source throughout the process, achieving compliance with "physical isolation".

[0024] This modular valve wall 1 is ready to use immediately, and centralized control significantly reduces training difficulty; new employees can master the operation process in just 10 minutes. It significantly saves costs and has also been recognized by fire safety inspection units.

[0025] In summary, this utility model, through modular assembly and centralized control design, meets the core requirements of national standards with the lowest cost and shortest construction period, providing a "time-saving, land-saving, and compliant" fire protection upgrade example for energy storage scenarios in booster stations, and has both practicality and promotional value.
