Description

Technical Field

[0001] This utility model belongs to the field of fire protection technology for energy storage equipment, and specifically relates to a fire linkage structure for an energy storage compartment. Background Technology

[0002] As a key facility in the new energy field, energy storage compartments integrate numerous sophisticated devices such as battery compartments and supercapacitor compartments. While these devices efficiently store energy, they also harbor significant fire hazards. If a device malfunctions and causes a fire, the relatively enclosed space within the energy storage compartment allows heat and smoke to accumulate rapidly, often leading to a catastrophic fire that can destroy the entire energy storage system.

[0003] However, existing fire protection structures have many drawbacks. Currently, most fire-fighting equipment within energy storage compartments operates independently, lacking an effective linkage mechanism. This poor linkage makes it impossible to respond quickly and effectively when a fire occurs. By the time a fire is discovered and fire-fighting equipment is manually activated, the optimal time for extinguishing the fire has often passed, and the fire may already be out of control.

[0004] This could not only cause severe damage to the equipment inside the energy storage compartment, affecting the normal operation of the entire energy storage system, but also potentially trigger secondary disasters such as explosions and toxic gas leaks, posing a significant threat to the surrounding environment and personnel safety, and causing incalculable losses. Therefore, improving the fire protection structure of the energy storage compartment and enhancing the interoperability of fire protection equipment have become crucial issues that urgently need to be addressed. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of poor linkage and low fire extinguishing efficiency of existing energy storage compartment fire-fighting equipment, and to propose a fire-fighting linkage structure for energy storage compartments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire-fighting linkage structure for an energy storage compartment includes a fire detection system, a fire extinguishing system, a ventilation system, and a control unit installed inside the energy storage compartment;

[0008] The signal output terminal of the fire detection system is electrically connected to the signal input terminal of the control unit via a wire; the fire detection system is installed on the top inner wall of the energy storage compartment, the fire extinguishing system is installed on the side inner wall of the energy storage compartment, the ventilation system is installed on the outer wall of the energy storage compartment, and the air inlet and outlet of the ventilation system are connected to the internal space through through holes penetrating the wall of the energy storage compartment; the control unit is installed on the side inner wall of the energy storage compartment.

[0009] The fire extinguishing system and the ventilation system are electrically connected to the control unit via wires.

[0010] Furthermore, the fire detection system includes composite detectors.

[0011] Furthermore, the fire extinguishing system includes a fire extinguishing device, and the fire extinguishing device is provided with piping.

[0012] Furthermore, the fire extinguishing device is equipped with perfluorohexanone extinguishing agent.

[0013] Furthermore, nozzles are installed on the pipeline of the fire extinguishing device.

[0014] Furthermore, the nozzles are positioned above the battery clusters inside the energy storage compartment.

[0015] Furthermore, the ventilation system includes an axial flow explosion-proof fan.

[0016] Furthermore, the number of axial flow explosion-proof fans is at least two.

[0017] Furthermore, there are at least two axial flow explosion-proof fans, which are installed in the upper and lower parts of the energy storage compartment, respectively.

[0018] Furthermore, the coordinated response between the fire detection system, fire extinguishing system, and ventilation system.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] This invention proposes a fire-fighting linkage structure for an energy storage compartment. The invention includes a prefabricated energy storage compartment, a fire detection system, a fire extinguishing system, a ventilation system, and a control unit. Upon detecting a fire, the fire detection system transmits a signal to the control unit, which then activates the fire extinguishing and ventilation systems. The fire extinguishing system sprays extinguishing agent, and the ventilation system expels gases from the compartment. By linking the fire detection, fire extinguishing, and ventilation systems through the control unit, a rapid response can be achieved in the event of a fire, enabling timely fire suppression and the removal of harmful gases, significantly improving fire-fighting efficiency and effectively ensuring the safe operation of the prefabricated energy storage compartment. This invention provides rapid fire response, improves fire-fighting efficiency, and ensures the safe operation of the prefabricated energy storage compartment. The fire detection system is electrically connected to the control unit, enabling real-time and accurate monitoring of fire-related parameters such as temperature and smoke within the energy storage compartment. Upon detecting an anomaly, it quickly transmits a signal to the control unit, providing early warning of the fire and buying valuable time for subsequent response. Upon receiving the fire signal, the control unit immediately activates the fire extinguishing and ventilation systems. The fire suppression system rapidly releases extinguishing agents to precisely extinguish fires and minimize equipment damage; the ventilation system promptly removes smoke and harmful gases, improving the cabin environment and ensuring safe evacuation and rescue operations. The control unit intelligently adjusts the operating parameters of the fire suppression and ventilation systems based on the fire's scale and location, achieving precise fire suppression and efficient ventilation, avoiding resource waste and overreaction. All systems are integrated within the energy storage cabin and managed centrally by the control unit, facilitating routine maintenance, inspection, and monitoring, reducing operating costs, and enhancing overall fire safety.

[0029] Example 2

[0030] See Figure 1 A fire-fighting linkage structure for an energy storage compartment includes a fire detection system 2, a fire extinguishing system 3, a ventilation system 4, and a control unit 5 installed inside the energy storage compartment 1.

[0031] The signal output terminal of the fire detection system 2 is electrically connected to the signal input terminal of the control unit 5 via a wire; the fire detection system 2 is installed on the top inner wall of the energy storage compartment 1, the fire extinguishing system 3 is installed on the side inner wall of the energy storage compartment 1, the ventilation system 4 is installed on the outer wall of the energy storage compartment 1, and the air inlet and outlet of the ventilation system 4 are connected to the internal space through through holes penetrating the wall of the energy storage compartment 1; the control unit 5 is installed on the side inner wall of the energy storage compartment 1.

[0032] The fire extinguishing system 3 and the ventilation system 4 are electrically connected to the control unit 5 via wires.

[0033] Fire detection system 2 is electrically connected to control unit 5. Once a fire signal is detected, it can quickly transmit the information to control unit 5. Control unit 5, as the core of the entire fire-fighting linkage structure, can quickly make judgments and issue commands, simultaneously activating fire suppression system 3 and ventilation system 4. This rapid response and coordinated operation between systems enables effective measures to be taken in the early stages of a fire, controlling its spread and buying valuable time for the safety of equipment and personnel inside the energy storage compartment. Control unit 4 can intelligently adjust the operating modes and parameters of fire suppression system 3 and ventilation system 4 based on different information fed back by fire detection system 2, such as fire scale, location, and rate of development. For small-scale localized fires, control unit 5 can activate only the local fire suppression devices, avoiding excessive use of fire suppression resources; for fires that may produce toxic or harmful gases, control unit 5 can optimize the operation of the ventilation system to promptly remove harmful gases, ensuring the safety of rescue personnel. Fire suppression system 3 is electrically connected to control unit 5 and can be activated immediately upon receiving commands from control unit 5 to extinguish the fire. Based on the characteristics of energy storage compartment 1 and the type of fire, appropriate extinguishing media and methods are selected, such as gas extinguishing and dry powder extinguishing, to quickly reduce the temperature of the fire and isolate oxygen, thereby achieving effective fire extinguishing and minimizing damage to the equipment inside energy storage compartment 1, thus reducing economic losses. Ventilation system 4 is electrically connected to control unit 5. During a fire, control unit 5 can adjust the operation of ventilation system 4 according to the actual situation. On the one hand, in the early stages of a fire, proper ventilation can prevent the accumulation of combustible gas and avoid more serious accidents such as explosions; on the other hand, during fire extinguishing, ventilation system 4 can exhaust smoke and harmful gases, improving the fire scene environment and providing better conditions for rescue personnel to enter the fire scene, thus improving rescue efficiency. Integrating fire detection system 2, fire extinguishing system 3, ventilation system 4, and control unit 5 within energy storage compartment 1 forms an organic whole, facilitating centralized management and maintenance of the fire safety of energy storage compartment 1. Through the unified control unit 5, status monitoring, parameter setting, and fault diagnosis of each subsystem can be achieved, improving the manageability and maintainability of the entire fire linkage structure and reducing operation and maintenance costs.

[0034] Fire detection system 2 includes a composite detector. This composite detector in system 2 can detect multiple fire characteristic parameters comprehensively, enabling more accurate and timely detection of fire hazards compared to single-type detectors. It simultaneously detects smoke concentration, temperature changes, and specific gas components. Different stages of fire development exhibit different combinations of characteristics, and the composite detector can comprehensively capture this information, improving the accuracy and reliability of fire detection, reducing false alarm rates, and ensuring that alarms are issued in the early stages of a fire.

[0035] Fire extinguishing system 3 includes fire extinguishing devices and piping for the fire extinguishing devices.

[0036] The fire extinguishing system uses perfluorohexanone (PFH) as the extinguishing agent. PFH has excellent insulation, environmental friendliness, and fire extinguishing efficiency. In an environment like energy storage compartment 1, where electrical safety requirements are extremely high, the use of PFH can prevent secondary damage to electrical equipment such as batteries during the fire extinguishing process. Furthermore, it leaves no residue after extinguishing the fire and will not affect the subsequent normal operation of the equipment.

[0037] The fire extinguishing system is equipped with nozzles on its piping. The piping, specifically designed for perfluorohexanone fire extinguishing systems, ensures a stable and even delivery of the extinguishing agent to each nozzle, guaranteeing proper distribution of the extinguishing agent within the energy storage compartment and achieving comprehensive, all-around fire extinguishing coverage.

[0038] The nozzles are positioned above the battery clusters within the energy storage compartment 1. This placement allows the extinguishing agent to be directly sprayed onto high-risk fire areas. When a fire occurs, the extinguishing agent can quickly cover the surface of the battery clusters, rapidly reducing the temperature and isolating oxygen, effectively suppressing the spread of fire and improving extinguishing efficiency.

[0039] Ventilation system 4 includes axial flow explosion-proof fans. These fans are explosion-proof and can withstand the flammable and explosive gas environment that may exist within the energy storage compartment, ensuring the safe operation of ventilation system 4 in emergencies such as fires. Simultaneously, the axial flow fans have a large air volume and moderate air pressure, enabling them to quickly and effectively expel smoke and harmful gases from the compartment. At least two axial flow explosion-proof fans are installed at the upper and lower parts of the energy storage compartment 1, respectively, forming an upward and downward convection ventilation pattern. This layout can more effectively promote air circulation within the compartment and improve ventilation efficiency. In the event of a fire, it can quickly expel smoke and harmful gases outside the compartment, creating a favorable environment for personnel evacuation and firefighting rescue.

[0040] Two axial-flow explosion-proof fans are installed at the upper and lower parts of the energy storage compartment 1, respectively. The installation of at least two axial-flow explosion-proof fans at the upper and lower parts of the energy storage compartment 1 creates a vertical convection ventilation pattern. This layout can more effectively promote air circulation within the compartment and improve ventilation efficiency. In the event of a fire, it can quickly expel smoke and harmful gases from the compartment, creating a favorable environment for personnel evacuation and firefighting and rescue operations.

[0041] The fire detection system 2, fire extinguishing system 3, and ventilation system 4 work in tandem. Fire detection system 2 monitors environmental parameters within the energy storage compartment 1 in real time, including temperature and smoke concentration. Upon detecting any signs of fire, it immediately issues an alarm signal, providing timely information support for subsequent coordinated responses. When fire detection system 2 issues an alarm, control unit 5 quickly activates the coordinated response mechanism. On one hand, fire extinguishing system 3 immediately activates, releasing perfluorohexanone extinguishing agent to extinguish the fire; on the other hand, ventilation system 4 simultaneously starts, with axial flow explosion-proof fans beginning operation to expel smoke and harmful gases. This multi-system collaborative approach enables rapid action in the early stages of a fire, controlling its spread and minimizing fire damage.

[0042] The control unit 5 can intelligently adjust the operating parameters of the fire extinguishing system 3 and the ventilation system 4 based on information such as the fire scale and location fed back by the fire detection system 2. For small-scale fires, the release of extinguishing agent can be appropriately reduced, while the wind speed of the ventilation system 4 can be adjusted to prevent excessive ventilation from causing the fire to spread. For large-scale fires, the spray intensity of the extinguishing agent is increased, and the ventilation effect is enhanced to control the fire as quickly as possible. The linkage response mechanism not only considers the fire extinguishing effect but also fully considers personnel safety and equipment protection. When a fire occurs, the ventilation system 4 promptly discharges harmful gases, providing a safe passage for personnel evacuation; at the same time, the fire extinguishing system 3 selects appropriate extinguishing agents and extinguishing methods to avoid unnecessary damage to equipment and reduce economic losses.

[0043] Example 2

[0044] See Figure 2 A fire-fighting linkage structure for an energy storage compartment includes an energy storage compartment 1, a fire detection system 2, a fire extinguishing system 3, a ventilation system 4, and a control unit 5, all installed in the energy storage compartment 1. The fire detection system 2 is electrically connected to the control unit 5 and is used to detect fire within the energy storage compartment 1 and transmit signals to the control unit 5. The fire detection system 2 includes composite detectors (smoke, temperature, CO, VOC, etc.). Both the fire extinguishing system 3 and the ventilation system 4 are electrically connected to the control unit 5. After receiving signals from the fire detection system 2, the control unit 5 controls the activation of the fire extinguishing system 3 and the ventilation system 4. The fire extinguishing system 3 includes a perfluorohexanone fire extinguishing device and corresponding piping and nozzles, enabling cluster-level control and multiple sprays. The ventilation system 4 includes an axial flow explosion-proof fan installed on the energy storage compartment for exhausting gases from inside the compartment.

[0045] Operating Procedure: When the fire detection system 2 detects a fire in the energy storage compartment 1, such as excessive smoke concentration or rising temperature, it sends a signal to the control unit 5. Upon receiving the signal, the control unit 5 immediately activates the fire extinguishing system 3, and the perfluorohexanone extinguishing device sprays perfluorohexanone extinguishing agent through pipelines and nozzles; simultaneously, the axial flow explosion-proof fan of the ventilation system 4 is activated to exhaust harmful gases and smoke from the compartment, improving the fire extinguishing effect.

[0046] This invention enables the linkage of the fire detection system 2, the fire extinguishing system 3, and the ventilation system 4 through the control unit 5. It can respond quickly when a fire occurs, extinguish the fire in time, and discharge harmful gases, which greatly improves fire protection efficiency and effectively ensures the safe operation of the energy storage compartment.

[0047] Example 3

[0048] This embodiment uses a 20MW energy storage capacity as an example, and the fire protection design considers the occurrence of one fire at a time. A fire water supply system is installed in the energy storage area, with fire water drawn from the plant's overall fire water system. The existing plant's fire pipeline network is approximately 200m away from the energy storage area. Calculations show that the existing plant's fire hydrant pumps can meet the fire flow and pressure requirements of the energy storage area. In this embodiment, the fire water volume is 20L / s, the fire duration is 3 hours, and the total fire water volume is 216m³. 3 .

[0049] The energy storage compartment integrates a fire detection and alarm system and a gas extinguishing system. The fire detection and alarm system can detect abnormalities within the prefabricated compartment and automatically or manually activate the gas extinguishing system. The gas extinguishing system is planned to be a perfluorohexanone cabinet-type automatic extinguishing system. The energy storage compartment fire alarm system can operate independently of the plant-wide fire alarm system. Its main functions are as follows:

[0050] The entire gas fire suppression system has three activation modes: automatic control, manual control, and mechanical emergency operation. The system also includes an automatic / manual operation switch to allow switching between automatic and manual operation.

[0051] The system can automatically detect fires, automatically alarm, automatically activate the fire extinguishing system, operate related equipment that is interlocked with the system, release extinguishing agents, and correspondingly shut down fire dampers, fans, doors and windows and other facilities in the protected area.

[0052] The system is equipped with an independent emergency manual operation mechanism, which can be used to release gaseous fire extinguishing agent in case other operation methods fail. The emergency manual operation mechanism is mechanical and can complete all operations of releasing the fire extinguishing agent at one location.

[0053] The entire system is equipped with alarm bells, audible and visual alarms, and gas release indicator lights for fire and extinguishing agent release. In addition, visual alarms are also installed at the entrances and exits of the protected area.

[0054] The system has a self-testing system that performs regular automatic inspections, monitors for faults, and generates fault alarms.

[0055] When a fire occurs outside the storage compartment and threatens the safety of the energy storage system, the plant's automatic fire alarm system and fire-fighting water system will be activated and the fire will be extinguished in a timely manner.

[0056] Batteries require a certain ambient temperature to operate safely and normally. Increased temperature significantly impacts battery life. Air conditioning and temperature control systems use cold air ducts to blow cool air into all batteries, dissipating the heat generated during battery operation and thus achieving thermal management.

[0057] The energy storage system is equipped with a battery management system (BMS), which features high-precision detection and reporting, fault alarms, data upload and storage, battery protection, parameter setting, active balancing, and battery pack SOC calibration. Battery protection functions include short-circuit protection, overcurrent protection, cell overcharge protection, cell over-discharge protection, cell over-temperature protection, and communication anomaly protection, providing comprehensive safety assurance.

[0058] The battery compartment is equipped with a perfluorohexanone automatic fire suppression system, capable of quickly detecting fire hazards, issuing alarm signals, and extinguishing fires. An independently powered fire-sensing fiber optic cable can be laid inside the battery compartment as a reliable means of follow-up monitoring to assess the effectiveness of fire suppression and battery status. Even after a battery fire is extinguished, there is a possibility of reignition within 24 hours, potentially leading to secondary fires in electrical equipment. Therefore, depending on the project's specific circumstances, additional fire extinguishers, fire-resistant masks, fire hydrants, emergency water sources, and fire sand will be provided for emergency use in case of fire.
