Description

Technical Field

[0001] The present invention relates to the technical field of energy storage ventilation control, and in particular to a ventilation system and sealing method for a prefabricated energy storage cabin. Background Art

[0002] In energy storage scenarios involving flammable and explosive hazards, such as battery storage cabins, containerized mobile energy storage stations, energy storage systems for new energy vehicles, and energy storage systems for hazardous materials warehouses, the design of ventilation control systems for energy storage firefighting is particularly important to prevent the rapid and explosive accumulation of flammable gases in a space, which could seriously endanger property and personal safety. Existing ventilation systems for energy storage are limited in functionality, lacking fans or push rods. They also lack voltage and current detection capabilities and manual / automatic switching during operation. When an anomaly occurs, there's no timely feedback signal to the fire control unit for troubleshooting. This can prevent flammable gases from being discharged, leading to excessive concentrations and explosion risks.

[0003] For example, patent document CN222141583U introduces a PLC-based explosion-proof fan control system that can quickly alarm and collect leaked gas when a combustible gas leak is detected to prevent it from spreading. However, this solution has several problems: First, it relies solely on combustible gas detection and does not monitor the operating status of the fan and push rod in real time, which may lead to ventilation failure; second, it lacks voltage and current detection, and cannot warn of abnormal energy consumption and potential faults; third, the control mode is single and lacks manual-automatic switching function, making the equipment difficult to operate during debugging, maintenance, or when the automatic control module fails; finally, the interaction with the fire host is limited, and the equipment operating parameters and fault codes cannot be uploaded, which affects emergency decision-making and troubleshooting.

[0004] For example, patent document CN110630311B describes a multi-branch dual-horizontal well compressed air energy storage ventilation system for coal mines. This system aims to address issues such as the large size and fragility of heat pump heat exchanger units in underground coal mine ventilation systems, improve construction efficiency and safety, and save costs and reduce environmental impact. However, this solution has limitations: first, it is only applicable to underground coal mines and not to ground or mobile energy storage scenarios; second, it lacks combustible gas monitoring and ventilation equipment status monitoring, which may lead to ventilation failure; third, it cannot interact with the fire protection system, making it difficult to implement fire emergency response; and fourth, the single control mode lacks manual and automatic switching, which affects emergency response and troubleshooting.

[0005] Therefore, a ventilation control system and method for energy storage prefabricated cabins are needed, which integrates the real-time monitoring function of the operating status of fans and push rods to ensure that the ventilation system can operate effectively at any time; warn of abnormal energy consumption and potential failures to avoid equipment damage and fire risks; enhance the flexibility and operability of the equipment, facilitate debugging, maintenance and emergency response, and achieve full interaction with the fire host. Summary of the Invention

[0006] In response to the above-mentioned problems, the purpose of the present invention is to provide a ventilation system and sealing method for a prefabricated energy storage cabin, which integrates fan and push rod status monitoring and voltage and current detection, provides manual / automatic switching, interacts with the fire host, and ensures the ventilation safety of the energy storage cabin.

[0007] Embodiments of the present invention provide a ventilation system and a sealing method for a prefabricated energy storage cabin.

[0008] A first aspect: A ventilation system for a prefabricated energy storage cabin, comprising:

[0009] The detection module collects combustible gas data from the energy storage compartment based on the fire detector and sends the detection signal to the control module through the fire host;

[0010] The control module sends a control signal to the push rod module and the fan module according to the detection signal of the detection module;

[0011] The push rod module controls the push rod movement and opens and closes the air inlet cover according to the control signal of the control module;

[0012] The fan module controls the fan action according to the control signal of the control module;

[0013] The feedback module collects push rod action and fan action signals and feeds them back to the control module.

[0014] Optionally, a sealed rubber ring is provided between the air outlet cover and the fan, and the sealed rubber ring is close to one side of the air outlet cover and has an inclined surface.

[0015] Optionally, it also includes:

[0016] An input module is used to detect a manual control signal, an automatic control signal or a manual / automatic switching signal and send it to a control module;

[0017] Output module, used to output abnormal feedback signals and manual indicator light signals.

[0018] Optionally, it also includes:

[0019] The power module is used to convert the input 220V AC power into 24V DC power, 5V DC power, and 3.3V DC power to meet the power supply requirements of various parts of the system.

[0020] Optionally, it also includes:

[0021] Download module, used to save system operation processing data.

[0022] Optionally, the push rod module includes a push rod relay module and a limit detection module, wherein:

[0023] The push rod relay module drives the push rod to move, detects the push rod limit signal through the limit detection module, and feeds back the limit signal to the push rod relay module to stop the push rod movement.

[0024] Optionally, one fan module corresponds to two push rod modules, one push rod module is used to control the movement of the air inlet push rod, and the other is used to control the movement of the air outlet push rod.

[0025] A second aspect: A ventilation and sealing method for a prefabricated energy storage cabin, the method comprising the steps of:

[0026] S1. Monitor combustible gas in the energy storage compartment;

[0027] S2. When the combustible gas concentration reaches the threshold, the push rod moves to open the air vent cover and start the fan for ventilation;

[0028] S3. When the combustible gas concentration is lower than the threshold, the fan is turned off to stop ventilation, and the push rod moves to close the air vent cover, forming a closed space in the energy storage cabin;

[0029] Among them, the system detects abnormal conditions during the start-up and shutdown of the push rod and fan and the operation process, and performs fault processing.

[0030] Optionally, the abnormal state includes an abnormal current or abnormal voltage state, wherein

[0031] When the fan is working, the feedback module monitors the fan current every 5 seconds. If the current is abnormal, it will monitor again after 1 second. If it is abnormal for three consecutive times, the abnormal signal will be fed back to the system.

[0032] When the push rod works abnormally, it will be monitored again after an interval of 1s. When it is abnormal three times in a row, the feedback module will feed back the abnormal signal to the system.

[0033] Optionally, the system feeds back the abnormal status to the fire host for alarm display.

[0034] Beneficial effects of the present invention:

[0035] 1. This invention uses fire detection probes to monitor combustible gas concentrations in real time. When the concentration exceeds a specified threshold, the system automatically triggers a push rod to open the air vents and start the fan for ventilation, effectively reducing the combustible gas concentration in the cabin to below the safe threshold, thereby reducing the risk of explosion. The voltage and current of the fan and push rod are monitored in real time. If an anomaly is detected, the system immediately cuts power and sends a feedback signal to the fire control unit, preventing fires or ventilation failures caused by equipment failure.

[0036] 2. The present invention supports switching between manual and automatic control modes through an input module, so that the fan and push rod can be manually controlled during the debugging and maintenance process. When a fault occurs in the automatic mode, the system can still perform emergency operations, thereby improving the adaptability of the system. The push rod upper and lower limit detection modules ensure that the air outlet is fully opened before starting the fan to avoid ineffective ventilation; when the concentration of the energy storage cabin is lower than the set threshold, the system will shut down the equipment in sequence to reduce energy waste.

[0037] 3. The present invention utilizes an inclined sealing rubber ring, which provides excellent sealing performance. When the hatch is closed, the inclined sealing rubber ring fits tightly against the hatch frame, effectively preventing gas leakage and ensuring stable control of the gas concentration within the cabin. Furthermore, the sealing rubber ring is made of wear-resistant and high-temperature-resistant materials, making it less susceptible to aging and deformation over time, thus ensuring the reliability and durability of the system. Furthermore, the sealing rubber ring design facilitates removal and replacement, reducing system maintenance costs.

[0038] 4. This system uploads combustible gas concentration data, equipment status, and fault codes in real time, supporting active query and abnormality reporting by the fire host, thereby improving emergency response efficiency. The dry contact input / output module and relay control module work together to form a dual interactive link of bus communication and hard-wired connection, ensuring the stability and reliability of the control signal.

[0039] 5. The present invention uses voltage and current detection modules to monitor the operating parameters of the fan and push rod in real time. Once an abnormality occurs, the system will automatically cut off the power supply and feedback to the fire host to avoid safety hazards caused by ventilation failure and equipment failure. At the same time, a manual-automatic switching mode is set to facilitate equipment debugging and maintenance, and manual control can be performed when the automatic control module fails, improving the system's operational flexibility and emergency response capabilities. It can achieve two-way interaction with the fire host, not only receiving signals from the fire host to trigger ventilation actions, but also uploading equipment operating parameters and fault codes to assist in emergency decision-making and troubleshooting.

[0047] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] The current energy storage ventilation system only has basic functions, lacking voltage and current monitoring of the fan 100 and actuator 200 during operation, as well as manual and automatic mode switching. In the event of an abnormality, the system cannot promptly report it to the fire control unit, resulting in a delay in resolving the fault. This can lead to the accumulation of combustible gases and excessive concentrations, posing an explosion hazard.

[0049] In response to the above problems, the present invention provides a ventilation system for a prefabricated energy storage cabin.

[0050] Example 1:

[0051] like Figure 1 As shown, Figure 1 The structural diagram of the ventilation control system for energy storage fire fighting of the present invention, Figure 2 The schematic diagram of the system structure is as follows. The system includes: detection module, control module, push rod 200 module, fan 100 module and feedback module, among which:

[0052] The detection module collects combustible gas data from the energy storage compartment based on the fire detector and sends the detection signal to the control module through the fire host.

[0053] The detection module is implemented based on the existing fire protection system composite detection head. The composite detection head has the characteristics of high sensitivity and fast response speed, and can accurately monitor the concentration of combustible gas in the energy storage cabin in real time.

[0054] The control module sends a control signal to the push rod 200 module and the fan 100 module based on the detection signal of the detection module.

[0055] The control module can use the GD32F103CBT6 control chip, which has an ARM Cortex-M3 core, a main frequency of up to 108MHz, and excellent performance; its instruction set is compatible with the ARM standard, and it has a rich development tool chain, which facilitates rapid development; it uses the LQFP48 package, which is compact and convenient for PCB wiring and heat dissipation design; and the chip is domestically produced, with stable supply.

[0056] After receiving the detection signal, the control module determines whether ventilation measures need to be initiated based on the preset threshold. If the combustible gas concentration exceeds the threshold, the control module will immediately issue a command to activate the push rod 200 module and the fan 100 module.

[0057] The push rod 200 module controls the movement of the push rod 200 and opens and closes the air inlet cover 400 according to the control signal of the control module; the fan 100 module controls the movement of the fan 100 according to the control signal of the control module.

[0058] One of the fan 100 modules corresponds to two push rod 200 modules. One push rod 200 module is used to control the movement of the air inlet push rod 200, and the other is used to control the movement of the air outlet push rod 200, opening the air outlet cover 400 to allow the air in the battery compartment to flow quickly and reduce the concentration of combustible gas.

[0059] The actuator 200 module is responsible for controlling the opening and closing of the vents. Upon receiving instructions from the control module, the actuator 200 module swiftly activates to open the vents, providing emergency ventilation for the energy storage compartment. The fan 100 module activates when the actuator 200 module opens the vents, accelerating air circulation and effectively reducing the concentration of combustible gases within the energy storage compartment.

[0060] Further, such as Figure 5 As shown, a sealed rubber ring 300 is provided between the air inlet cover plate 400 and the fan 100 , with an inclined surface 310 .

[0061] The fan 100 is fixed on the mounting frame 500, and a sealed rubber ring 300 is provided between the air outlet cover 400 and the fan 100. The sealed rubber ring 300 is close to one side of the air outlet cover 400. The air outlet cover 400 is rotatably connected to the mounting frame 500. The air outlet cover 400 is connected to the telescopic ends of the two push rods 200. The two push rods 200 perform telescopic movements according to the control signal respectively, thereby driving the air outlet cover 400 to rotate around the rotating connection point to realize the opening and closing of the air outlet.

[0062] The sealed rubber ring 300 can keep the energy storage cabin in a relatively closed environment when the air vent cover 400 is closed, which is conducive to accurately detecting the combustible gas concentration inside the energy storage cabin. When the combustible gas concentration exceeds the safety threshold, the system starts immediately and the push rod 200 module moves quickly.

[0063] The sealing rubber ring 300, near the tuyere cover 400, features a top-down inclined surface 310. This resists wear caused by repeated pressure from the tuyere cover 400, improving the sealing effect within the energy storage compartment. Furthermore, the inclined surface 310 guides the airflow between the tuyere cover 400 and the sealing rubber ring 300 when the tuyere cover 400 is closed, reducing direct impact on the sealing rubber ring 300 and further extending its service life. This design not only improves ventilation efficiency but also effectively ensures the safe operation of the energy storage compartment.

[0064] The feedback module is used to collect the action signals of the push rod 200 and the fan 100 and feed them back to the control module.

[0065] The feedback module monitors the operating status of the actuator 200 and fan 100 modules in real time and transmits this information back to the control module. Furthermore, in the event of an abnormality, such as a failure of the actuator 200 or fan 100, the feedback module promptly sends an alarm signal to the fire control unit, ensuring that the fault is promptly displayed and addressed.

[0066] Furthermore, the system also includes an input module, which can use three-way passive dry contact input to detect manual control signals, automatic control signals or manual / automatic switching signals and send them to the control module;

[0067] Output module: The output module can adopt two-way passive dry contact output to output abnormal feedback signal and manual indicator light signal.

[0068] When the system detects the manual / automatic switching signal, it outputs a manual indicator light signal. At this time, the operation of the fan 100 and the push rod 200 can be controlled by the manual control signal button on the manual control box.

[0069] The input and output modules work together to enhance the system's flexibility and responsiveness. The input module accurately captures all control signals, whether manual, automatic, or switching between manual and automatic, and transmits them to the control module in real time, ensuring the system can quickly adjust its operating mode based on actual needs. The output module, on the other hand, is responsible for clearly displaying system status information, such as abnormal feedback and manual indicator signals, to the user, helping them to promptly understand the system status and take appropriate countermeasures. This design not only improves system reliability and security, but also significantly enhances the user experience.

[0070] In addition, the system is equipped with a power module, which is responsible for providing a stable and reliable power supply to the entire system, ensuring that all components can work normally in an emergency.

[0071] The power module converts 220V AC input into DC 24V, DC 5V, or DC 3.3V to power the entire system.

[0072] For example, the fan 100 is powered by AC 220V, the push rod 200 is powered by DC 24V, and each module is powered by DC 5V or DC 3.3V.

[0073] The power module also features overvoltage, undervoltage, and short-circuit protection, automatically cutting off power in the event of power fluctuations or abnormalities to prevent system damage. Furthermore, the power module utilizes high-efficiency conversion circuitry to minimize power loss and improve energy efficiency. This design not only ensures stable system operation but also complies with modern energy conservation and environmental protection concepts.

[0074] Furthermore, to further enhance system stability and durability, the power module utilizes high-quality electronic components and an advanced heat dissipation design, ensuring stable power output even under prolonged, high-load operation. This design not only enhances overall system performance but also provides a strong guarantee for long-term, stable operation.

[0075] Furthermore, the system also includes a download module, which is used to save system operation processing data.

[0076] The download module features a large-capacity memory that records and stores key system data in real time, such as voltage and current parameters, operating status, and alarm logs. This data is crucial for subsequent system maintenance, troubleshooting, and performance optimization. Furthermore, the download module supports multiple data export methods, such as USB and network interfaces, allowing users to easily view and analyze system data at any time. This design not only improves system data management efficiency but also provides strong support for secure and reliable system operation.

[0077] Furthermore, the push rod 200 module includes a push rod 200 relay module and a limit detection module, wherein: the push rod 200 relay module drives the push rod 200 to move, detects the push rod 200 limit signal through the limit detection module, and feeds back the limit signal to the push rod 200 relay module to stop the push rod 200 from moving. When the fire probe detects that the combustible gas concentration in the cabin reaches the threshold, the fire host sends a signal to the control module. The control module first controls the two relay control modules to extend the air inlet push rod 200 and the air outlet push rod 200 to open the vent. When the upper and lower limit detection modules of the push rod 200 detect the upper limit feedback signal, the control module controls the relay control module to cut off the voltage of the air inlet and air outlet push rods 200, and controls the fan 100 relay control module to start the fan 100 for ventilation, thereby reducing the combustible gas concentration in the cabin. When the combustible gas concentration in the energy storage cabin falls below the alarm threshold, the fire host sends a signal to shut down the fan 100 and push rod 200.

[0078] Example 2:

[0079] like Figure 3 and Figure 4 As shown, based on the system of embodiment 1, the present invention further discloses a ventilation and sealing method for a prefabricated energy storage cabin, the method comprising the steps of:

[0080] S1. Monitor combustible gas in the energy storage compartment.

[0081] Combustible gases in the energy storage compartment include flammable and explosive gases such as hydrogen, methane, and carbon monoxide. These gases are monitored in real time by firefighting probes. The high sensitivity of the firefighting probes ensures the timely detection of gas leaks, providing valuable time for subsequent rapid response. During normal operation of the energy storage compartment, both the fan 100 and the push rod 200 are in the off state.

[0082] S2. When the combustible gas concentration reaches a threshold, the push rod 200 moves to push open the air vent cover 400 and start the fan 100 for ventilation.

[0083] When the fire probe detects that the combustible gas concentration in the cabin reaches the threshold, the fire host sends a signal to the control module.

[0084] The control module controls the relay control module to make the push rod 200 open the vent. When the upper and lower limit detection modules of the push rod 200 detect the upper limit feedback signal, the control module controls the relay control module to cut off the voltage of the push rod 200, and controls the fan 100 relay control module to open the fan 100 for ventilation, thereby reducing the concentration of combustible gas in the cabin.

[0085] S3. When the combustible gas concentration is lower than the threshold, the fan 100 is turned off to stop ventilation, and the push rod 200 moves to close the air vent cover 400.

[0086] When the fire probe detects that the combustible gas concentration in the cabin is lower than the threshold, the fire host sends a signal to the control module.

[0087] When the combustible gas concentration in the energy storage compartment is lower than the alarm threshold, the fire host sends a signal to the control module, and the control module turns off the fan 100 by controlling the fan relay control module; then the control module controls the relay control module to make the push rod 200 close the vent. When the upper and lower limit detection modules of the push rod 200 detect the lower limit feedback signal, the control module controls the relay control module to turn off the voltage of the push rod 200.

[0088] Furthermore, the system detects abnormal conditions during the start-up, shutdown and operation of the push rod 200 and the fan 100 and performs fault processing.

[0089] The feedback module includes a push rod 200 voltage and current detection module and a fan 100 voltage and current detection module. The push rod 200 voltage and current detection module is used to detect the voltage and current values ​​of the push rod 200 during the extension and retraction operation. When abnormal voltage and current are detected, the push rod 200 operation is shut down in time through the relay control module, and the abnormal signal is fed back to the fire host to promptly identify the cause of the fault and eliminate the fault.

[0090] Abnormal conditions include abnormal current or abnormal voltage conditions, where:

[0091] When the fan 100 is working, the feedback module monitors the current of the fan 100 every 5 seconds. If the current is abnormal, it will be monitored again after an interval of 1 second. If the abnormality occurs three times in a row, the abnormal signal will be fed back to the system.

[0092] When the push rod 200 works abnormally, it is monitored again at an interval of 1 second. When the abnormality occurs three times in succession, the feedback module feeds back the abnormal signal to the system.

[0093] Upon receiving the abnormality signal, the system immediately triggers an alarm and, through the control module, cuts off the power to the fan 100 and push rod 200 to prevent the fault from escalating or causing a more serious safety incident. Simultaneously, the system records detailed abnormality information to a built-in storage module, including the time and type of abnormality, as well as key parameters such as current and voltage at the time of the abnormality, providing data support for subsequent fault analysis and resolution. Furthermore, the system supports remote monitoring, allowing managers to view the system's operating status and abnormality records in real time through a remote terminal, enabling them to promptly identify and address potential safety hazards.

[0094] Furthermore, the positive and negative poles of the power supply are reversed when the push rod 200 is extended and retracted. When the concentration of combustible gas in the energy storage compartment is lower than the starting threshold of the fan 100, the fire host transmits a stop signal to the control module, which first stops the power supply of the fan 100 and then reverses the positive and negative poles of the power supply of the push rod 200. The power is cut off after the push rod 200 is retracted.

[0095] Furthermore, the system feeds abnormal conditions back to the fire control unit for alarm display, enabling real-time fault alarms and status display. Upon receiving the system's abnormal condition feedback, the fire control unit not only immediately triggers an audible and visual alarm, but also clearly displays key information such as the type of abnormality and its location on the display interface, enabling operators to quickly locate and take countermeasures. This instant feedback mechanism significantly improves the system's safety and reliability, ensuring more intelligent and efficient ventilation control in energy storage fire protection environments.

[0096] The fire control unit interacts with the ventilation control system, accurately receiving abnormal status information from the ventilation control system and updating the status data on the display interface in real time. Simultaneously, the fire control unit can send control commands to the ventilation control system, such as starting or stopping fan 100 and adjusting the status of push rod 200, enabling comprehensive monitoring and management of the ventilation control system. This efficient interaction mechanism further enhances the system's intelligence and provides a strong guarantee for the safe operation of energy storage fire protection environments.

[0097] The present invention also provides an electronic device, Figure 6 A schematic diagram of the structure of an electronic device provided by an embodiment of the present invention, such as Figure 6 As shown, the electronic device may include: a processor, a communications interface, a memory, and a communication bus, wherein the processor, the communications interface, and the memory communicate with each other via the communication bus.

[0100] S3. When the combustible gas concentration is lower than the threshold, the fan is turned off to stop ventilation, and the push rod moves to close the air vent cover, forming a closed space in the energy storage cabin;
