Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, and more specifically, to a fire water connection structure applied to an energy storage frequency regulation battery compartment. Background Technology

[0002] Energy storage frequency regulation technology can store energy when electricity demand is low and release it when demand is high, thereby balancing the power grid and ensuring the stability and reliability of power supply. Currently, the most widely used energy storage frequency regulation technology with fast adjustment response is mainly based on battery compartment charging and discharging regulation. However, battery energy storage may experience overheating, short circuits, and other issues during operation, which can easily lead to fires.

[0003] Currently, conventional fire extinguishing systems, along with supporting fire-fighting equipment such as conventional fire monitors, fire hydrants, and fire extinguishers, provide pressurized water through a water source connected to the fire hydrant when a fire occurs. Firefighters open the fire hydrant, connect the fire hose and water gun, and the fire hydrant is usually equipped with a valve to adjust the water pressure to meet different fire extinguishing needs.

[0004] However, due to the unique structural performance of the battery compartment, conventional firefighting methods such as fire monitors are ineffective in quickly and efficiently extinguishing fires. If fire hoses are continuously connected to the battery compartment, routine maintenance is crucial; leaks could damage the battery compartment and render it unusable, posing a safety hazard. Using conventional fire hydrant connections poses risks to firefighters' personal safety, and the sealing components of fire hose connections are prone to aging and deformation, affecting sealing performance. Rough threads can also lead to misalignment during installation. In extremely urgent fire rescue operations, such fire hose connections consume operator time, and leaks at the joints can result in insufficient water pressure, failing to achieve the purpose of emergency rescue. Therefore, for firefighting situations involving battery compartments, how to efficiently extinguish fires in the first instance while ensuring stable operation of the equipment during long-term standby periods is a pressing issue that needs to be addressed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an external fire water connection structure for a frequency regulation battery compartment in energy storage, which solves the problems mentioned in the background art. This structure can quickly connect to fire water pipes for fire extinguishing in the event of a fire, while maintaining dryness and eliminating the risk of leakage during daily operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An external fire water connection structure for an energy storage frequency regulation battery compartment includes a fire pipe and a fire diversion pipe. The fire pipe is equipped with a fire isolation valve. A transverse fire diversion pipe is connected to the upper end of the fire pipe, and the other end of the fire pipe is connected to an external main fire pipe. Seven sets of first connector seats are evenly installed on the fire diversion pipe. Two rows of fire extinguishing pipes are located on the right side of the fire pipe. A second connector seat of the same specification as the first connector seat is fixedly installed on the near end of each of the two rows of fire extinguishing pipes. A flexible metal hose is provided between the fire diversion pipe and the fire extinguishing pipes. Quick connectors of the same specification as the first connector seats are installed at both ends of the flexible metal hose. The two ends of the flexible metal hose are connected to the first connector seat and the second connector seat respectively via quick connectors.

[0008] Furthermore, the number of fire extinguishing pipes in each row is the same as the number of the first connectors, with seven sets provided. The far ends of the two rows of fire extinguishing pipes are respectively connected to two sets of energy storage battery compartments through underground laying.

[0009] Furthermore, the two rows of fire extinguishing pipes are supported and fixed by pipe supports, and the fire extinguishing pipes are fixed to the pipe supports by clamps.

[0010] Furthermore, the outer sides of both rows of fire extinguishing pipes, fire diversion pipes, fire pipes, and fire isolation valves are all wrapped with a thermal insulation protective layer.

[0011] Furthermore, a water outlet detection pipe is connected to the fire-fighting pipeline near the fire-fighting diversion pipe, and a manual valve is installed on the water outlet detection pipe.

[0012] Furthermore, an operating box is provided on the outside of the fire-fighting pipeline, and all structural parts are located inside the operating box. A lockable switch door is installed on the front side of the operating box.

[0013] Furthermore, both the fire-fighting pipes and the fire-extinguishing pipes are introduced into the control box through the bottom.

[0014] Furthermore, the fire isolation valve is normally closed, and the metal flexible hose is disconnected from the fire diversion pipe and the fire extinguishing pipeline when not in use, and is placed inside the control box.

[0015] Furthermore, when the metal hose is not in use, the quick connectors at both ends are sealed with plugs.

[0016] Furthermore, there are a total of fourteen sets of fire extinguishing pipes in the two rows. Each set of fire extinguishing pipes has an identification plate hanging near its end, which is engraved with a number that corresponds to the fire water inlet in the two sets of energy storage battery compartments.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model achieves the purpose of quickly connecting to fire-fighting water pipes for fire extinguishing in the event of a fire by setting up fixed fire-fighting pipelines that lead out from the required location of the energy storage battery compartment of the energy storage power station to the energy storage power station, thereby reducing personnel risks and accident losses. It also features a dedicated fire-fighting connector operation box. The pipeline does not require fire-fighting water during normal operation, keeping it dry and free from leakage risks. The fire-fighting pipeline is laid underground and equipped with an external insulation and protective layer to ensure no risk of damage.

[0019] 2. The main operating position, namely the fire hose connection control box, is located at a distance outside the entire energy storage power station, far away from the fire location. This can effectively avoid situations where personnel cannot approach and operate the equipment in the event of a fire, thus ensuring the safety of the operators.

[0020] 3. Fire extinguishing pipelines and fire protection pipelines are not connected when in standby mode to avoid water leakage and spraying due to accidental situations such as aging pipeline nozzles or false alarms, which could damage normally operating equipment;

[0021] 4. The metal hose uses quick-connect couplings for connection, which can be quickly connected to the corresponding fire extinguishing pipeline in case of an accident for water spraying and fire extinguishing. This simplifies the connection process, improves fire extinguishing efficiency, and when the metal hose is not in use, the quick-connect couplings at both ends are sealed with plugs. There is no fire water inside the metal hose, avoiding the maintenance difficulties and safety hazards that may be caused by long-term connection to fire water pipes, ensuring reliable backup and no risk of leakage.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Example:

[0032] like Figures 1 to 6 As shown, a fire water connection structure for a frequency regulation battery storage compartment includes a fire pipe 6 and a fire diversion pipe 4. A fire isolation valve 5 is installed on the fire pipe 6. The upper end of the fire pipe 6 is connected to the horizontal fire diversion pipe 4. The other end of the fire pipe 6 is connected to an external fire main pipe. Seven sets of first connector seats 12 are evenly installed on the fire diversion pipe 4. Two rows of fire extinguishing pipes 7 are provided on the right side of the fire pipe 6. A second connector seat 13 of the same specification as the first connector seat 12 is fixedly installed on the near end of each of the two rows of fire extinguishing pipes 7. A metal flexible hose 3 is provided between the fire diversion pipe 4 and the fire extinguishing pipe 7. Quick connectors 11 of the same specification as the first connector seat 12 are installed at both ends of the metal flexible hose 3. The two ends of the metal flexible hose 3 are connected to the first connector seat 12 and the second connector seat 13 respectively through the quick connectors 11. Through the combination of the metal flexible hose 3 and the quick connectors 11, a quick connection between the fire water source and the fire extinguishing pipe 7 is realized. In the event of a fire, water can be quickly connected to extinguish the fire in the battery compartment, greatly improving fire extinguishing efficiency. This design solves the problems of existing battery compartment fire protection systems, such as fire monitors and fire hydrants, which are often unable to extinguish fires quickly and effectively in battery compartment fires due to the special structural performance of the battery compartment. Furthermore, long-term connection to fire water pipes leads to heavy daily maintenance work and a high risk of fire water leakage.

[0033] In this embodiment, the number of fire extinguishing pipes 7 in each row is the same as the number of first connectors 12, and there are seven sets. The far ends of the two rows of fire extinguishing pipes 7 are connected to the two sets of energy storage battery compartments respectively through underground laying.

[0034] In this embodiment, the two rows of fire extinguishing pipes 7 are supported and fixed by pipe supports 9. The fire extinguishing pipes 7 are fixed to the pipe supports 9 by clamps 14. The pipe supports 9 provide solid support for the fire extinguishing pipes 7, preventing the pipes from sagging, shaking or shifting due to their own weight or external factors. At the same time, the clamps 14, as a key component connecting the pipes and the supports, ensure the stability of the pipes on the supports through their fastening function.

[0035] In this embodiment, the outer sides of the two rows of fire extinguishing pipes 7, the fire diversion pipe 4, the fire pipe 6, and the fire isolation valve 5 are all wrapped with thermal insulation protective layers. The thermal insulation protective layers can protect each structural part and reduce the risk of damage. At the same time, in cold weather, the thermal insulation protective layers can effectively prevent the water in the pipes from freezing due to low temperature, ensuring that the fire protection system is always available.

[0036] In this embodiment, a water outlet detection pipe 8 is connected to the fire-fighting pipeline 6 near the fire-fighting diversion pipe 4. A manual valve 10 is installed on the water outlet detection pipe 8. The water outlet detection pipe 8 is mainly used to monitor the water flow in the fire-fighting pipeline 6 to ensure that fire-fighting water can flow out smoothly for fire extinguishing in an emergency. Through the water outlet detection pipe 8, the water flow status of the fire-fighting pipeline 6 can be observed intuitively to determine whether the pipeline is unobstructed.

[0037] In this embodiment, an operating box 1 is provided on the outside of the fire-fighting pipeline 6, and all structural parts are located inside the operating box 1. A lockable switch door 2 is installed on the front side of the operating box 1.

[0038] In this embodiment, both the fire-fighting pipe 6 and the fire-extinguishing pipe 7 are introduced into the control box 1 through the bottom. The control box 1 protects the important structural parts of the fire-fighting pipe 6 system, effectively preventing them from being damaged by the outside world, thereby extending their service life and reducing the failure rate.

[0039] In this embodiment, the fire isolation valve 5 is normally closed. When not in use, the metal hose 3 is disconnected from the fire diversion pipe 4 and the fire extinguishing pipe 7 and placed inside the control box 1. The fire extinguishing pipe 7 and the fire pipe 6 are not connected when in use to avoid water leakage and spraying due to accidental situations such as pipe nozzle aging or false alarms, which could damage the normally operating equipment.

[0040] In this embodiment, when the metal hose 3 is not in use, the quick connectors 11 at both ends are sealed with plugs, and there is no fire water inside the metal hose 3. This avoids the maintenance difficulties and safety hazards that may be caused by long-term connection to the fire water pipe, ensuring reliable backup while eliminating the risk of leakage.

[0041] In this embodiment, there are fourteen sets of fire extinguishing pipes 7 arranged in two rows. Each set of fire extinguishing pipes 7 has a sign attached near its end, with a number engraved on it corresponding to a fire water inlet in each of the two energy storage battery compartments. The number on the sign corresponds one-to-one with the fire water inlet in the energy storage battery compartment, enabling operators to quickly locate the corresponding fire extinguishing pipe 7 and fire water inlet in an emergency, allowing for rapid and effective fire extinguishing operations and facilitating targeted operation during use.

[0042] like Figure 7 As shown, the energy storage power station has a total of 6 energy storage battery compartments. Each battery compartment contains 4 battery stacks and 1 central control cabinet, with 7 fire water interfaces leading out. All 42 fire water interfaces of the 6 battery compartments are led out to the outside of the energy storage power station area through underground fire extinguishing pipelines 7. The above-ground structure is covered with a protective cover, and the underground pipelines are protected against corrosion. The outdoor part of the energy storage power station is equipped with interface racks and stainless steel cabinets.

[0043] Among them, three pipes are led out from the main fire protection pipe to the fire protection pipe 6 outside the energy storage power station area, away from the energy storage power station, and are divided into three groups and equipped with fire protection connection operation boxes 1. Each operation box 1 is equipped with two rows of fire water interface fire extinguishing pipes 7 connected to the energy storage battery compartment. Each control box 1 contains 7 flexible metal hoses 3 extending from the fire diversion pipe 4, matching two rows of a total of 14 fire extinguishing pipes 7 to the fire water inlets of the battery compartment. The three control boxes 1 correspond to 21 flexible metal hoses 3 and 42 fire water inlets / pipes 7. The fire water inlets / pipes 7 inside the control box 1 are assigned unique numbers that correspond one-to-one with the fire water inlets in the battery compartment for targeted operation during use. A total of 21 inlets are extended from the control box 1 to ensure that all 7 inlets are connected for fire extinguishing in the event of a fire in a single battery compartment. During normal standby, the fire isolation valve 5 in each set of fire connector control boxes 1 is closed, and each flexible metal hose 3 has a quick connector 11 at its end for quick connection. The quick connector 11 has a removable and well-sealed plug inside to ensure reliable standby without any leakage risk.

[0044] It should be noted that the energy storage power station is equipped with a suitable high-sensitivity fire alarm system, equipped with heat and smoke detectors. The system has the functions of automatically detecting fires, automatically alarming, automatically starting fire extinguishing, and automatically uploading fire status. After detecting a fire hazard, it will issue a fire alarm through an alarm bell and an audible and visual alarm, which can be specified to which battery compartment and the corresponding access point.

[0045] The working principle of an external fire water connection structure applied to an energy storage frequency regulation battery compartment:

[0046] When a fire occurs in the battery compartment, the fire alarm system automatically detects the battery compartment number and the specific inlet number that need to be extinguished. After receiving the alarm, the on-duty personnel contact the fire pump to increase the fire water pressure. After the on-site rescue personnel arrive, they quickly identify the corresponding fire hose control box 1 based on the alarm information, open the plug on the metal hose 3, and connect the metal hose 3 to the fire extinguishing pipe 7 that needs to be extinguished through the quick connector 11. At this time, other spare metal hoses 3 remain reliably closed. After the connection is completed, the fire isolation valve 5 of this fire hose control box 1 is opened, so that the pressurized fire water can smoothly reach the target location through the pipeline, achieving precise fire extinguishing. At the same time, the operators are in a safe area and can gradually adjust or perform other operations according to the fire situation.

[0047] After completing the fire extinguishing operation, first operate the fire isolation valve 5 inside box 1, then remove the metal hose 3 used in this operation, drain the water in the hose, and seal the quick connector 11 on it with a plug. After confirming that there are no fire water leaks in the box, contact the shutdown of the additional fire pump, and the operation is complete.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
