Description

Technical Field

[0001] The present invention relates to the technical field of ship fire extinguishing, and more specifically, to a fire prevention control system for a ship battery room.

Background Art

[0002] In recent years, strengthening environmental protection and reducing the emission of polluting gases have become a common understanding among countries around the world, and new emission standards have been successively implemented in many countries. The type of energy is gradually being converted from fossil energy to low-carbon energy. Among them, the development of the electric vehicle industry is the fastest, and the power battery, which is one of the core components of electric vehicles, has also made great progress. The application of power batteries is also gradually penetrating from the electric vehicle industry to other industries. In the field of ships, electric ships equipped with lithium-ion batteries are environmentally friendly, pollution-free, safe, and have low usage costs, etc., and are favored in the shipping industry.

[0003] Electric ships are similar to electric vehicles in that they use a power battery as a power source. However, since ships have a greater driving force and longer navigation time, the total stored energy of the ship's power battery system is large, and the battery system is complex. Therefore, usually, multiple battery clusters are provided, and multiple battery packs are provided in each battery cluster. For example, in some electric ships, about 20 battery clusters are provided, and 10 - 40 battery packs are provided in each battery cluster, and a dedicated cabin (battery room) needs to be provided to arrange them. However, batteries are likely to generate a large amount of heat and harmful gases in a short time under conditions such as overheating, overcharging, internal short - circuit, and collision. In severe cases, there is a risk of ignition. Battery fires usually have characteristics such as sudden ignition, rapid spread of fire, and explosion. When one battery pack undergoes thermal runaway, the entire power battery system of the electric ship may undergo thermal runaway, leading to a fire. In addition, the navigation environment of ships is very different from that on land. When a fire breaks out on a ship in the open sea, it is difficult to provide rescue by external forces. Furthermore, compared with the battery management system of automobiles, ships are affected by random uncertainties such as meteorology, hydrology, waterways, and traffic, as well as frequent fluctuations and large change ranges of ship loads. Therefore, the battery management system is more complex. Therefore, the fire prevention control system for ship battery rooms is required to have higher reliability compared to electric vehicles, and it is further required that fire prevention control can be carried out even when a failure or malfunction occurs in a part of the battery management system.

[0004] Therefore, it has become an urgent issue that needs to be studied by technicians in the technical field to provide a highly reliable fire prevention control system for ship battery rooms to effectively solve the fire safety problems related to the large - scale storage and use of lithium batteries on ships, and to ensure the safe and reliable operation of electric ships.

[0022] As shown in FIGS. 1 to 3, in a fire control system for a ship battery room, a plurality of battery clusters are provided in the battery room. A plurality of battery packs are provided in each battery cluster. The battery packs are managed by a battery management system. The fire control system is independent of the battery management system. The fire control system includes a detection device, a fire suppression device, and a control device. Specifically, the detection device is used to detect fire information in the battery packs and the battery room. The detection device includes a detection device. The detection device includes a temperature sensor, a smoke sensor, a CO sensor, a hydrogen gas sensor, a VOC sensor, a flame sensor, CO 2It includes one or more of the sensors. The detection device can perform a composite judgment on the parameter signals detected by the detection device and transmit them to the control device. For example, the detection device can divide a fire into four-stage warnings: the latent period, the early warning period, the alarm period, and the open fire period according to the parameter range. Among them, in the case of level 2, 3, and 4 alarms, the detection information is transmitted to the control device. The fire suppression device is used to suppress a fire by injecting a fire extinguishing agent into a battery pack or a battery room. The control device receives the parameter signals transmitted from the detection device, judges and analyzes the parameter signals, and is used to transmit an execution command to the fire suppression device. In addition, the fire prevention control system may further include an audio-visual alarm device capable of outputting audio-visual alarm information. In this case, the control device controls the audio-visual alarm device. The detection device includes a first detection device and a second detection device. The first detection device and the second detection device are redundant with each other. The control device includes a first control device and a second control device. The first control device and the second control device are redundant with each other. The first control device is connected to the first detection device, and the second control device is connected to the second detection device. The first control device and / or the second control device is used to control whether the fire suppression device releases the fire extinguishing agent. Specifically, the first control device and the second control device may each independently control the activation of the fire suppression device, or may simultaneously control the activation of the fire suppression device. In the fire prevention control system of the present invention, the detection device and the control device are each made redundant, and a two-path monitoring-control process of the detection device - control device - fire suppression device is realized, thereby greatly improving the reliability of the fire prevention control system. In addition, the fire prevention control system of the present invention may be provided integrally with the battery management system, that is, the control device of the battery management system may be used as the first control device or the second control device of the present invention, or may be provided independently of the battery management system. By providing the fire prevention control system independently to monitor and control the fire in the ship battery room independently, it does not cause any additional interference and control to the safety of ship operation and the battery power system, and has a detection alarm and a fire extinguishing function even when the battery power of the ship fails.

[0023] The fire suppression device includes a cluster-level suppression device and a cabin-level suppression device. One cluster-level suppression device is provided corresponding to one or more battery clusters. The cluster-level suppression device is used to inject a fire extinguishing agent into the battery packs within the battery cluster, and the cabin-level suppression device is used to inject a fire extinguishing agent into the battery storage room. Specifically, in the present invention, one cluster-level suppression device may be provided corresponding to one battery cluster, or one cluster-level suppression device may be provided corresponding to a plurality of battery clusters. For example, one cluster-level suppression device may be provided corresponding to two to three battery clusters. The cluster-level suppression device is provided close to the corresponding battery cluster so that the fire extinguishing agent in the cluster-level suppression device can be quickly injected into the battery pack where ignition has occurred. In the present invention, with the battery cluster as the division unit, the battery storage room is divided into a plurality of areas, and one fire suppression device (cluster-level suppression device) is provided corresponding to each of the divided areas. When a battery pack in a certain battery cluster undergoes thermal runaway and catches fire, the corresponding cluster-level suppression device can extinguish the fire of the battery pack alone, and the response of the fire suppression device to the ignition site is fast. Compared with the conventional method of flooding the cabin to extinguish the fire on a ship, the fire prevention control system of the present invention can locally suppress the fire before it spreads, thereby reducing the damage to the power battery system of the electric ship. Furthermore, the present invention is provided with a cabin-level suppression device for the battery storage room. The cabin-level suppression device injects a fire extinguishing agent into the entire battery storage room. When a local fire is suppressed and the fire spreads, it can be extinguished by the cabin-level suppression device.

[0024] The first control device includes a remote control host 1 and a first control panel connected to the remote control host 1. The second control device includes a local control host 2 and a second control panel connected to the local control host 2. The remote control host 1 and the local control host 2 are redundant with each other. The remote control host 1 and the local control host 2 further have the function of monitoring and displaying the operating states of all fire suppression devices. The first control panel and the second control panel are redundant with each other. The first control panel and / or the second control panel controls whether the fire suppression device releases the fire extinguishing agent. That is, the first control panel and the second control panel may independently control the activation of the fire suppression device, or may simultaneously control the activation of the fire suppression device. The first control panel and the second control panel are provided inside the fire suppression device. The local control host 2 is provided outside the battery room. The remote control host 1 is provided inside the ship's steering room. In the present invention, redundant control of the fire suppression device is realized by the remote control host - first control panel - fire suppression device and the local control host - second control panel - fire suppression device, and the communication reliability of the activation of the fire suppression device is improved. The local control host 2 may be provided near the door of the battery room, for example, on one side of the battery room door. The remote control host 1 is provided inside the ship's steering room. By providing the local control host 2 and the remote control host 1 at different positions on the ship, the staff can quickly notice the fire and take measures. In the present invention, the fire suppression device includes a cluster-level suppression device and a cabin-level suppression device. For the sake of easy distinction, the first control panel and the second control panel in the cluster-level suppression device of the present invention are defined as a first cluster-level control panel 3 and a second cluster-level control panel 4, and the first control panel and the second control panel in the cabin-level suppression device are defined as a first cabin-level control panel 5 and a second cabin-level control panel 6. The first cluster-level control panel 3 and the second cluster-level control panel 4 are redundant with each other. The first cabin-level control panel 5 and the second cabin-level control panel 6 are redundant with each other. One corresponding first cluster-level control panel 3 and one second cluster-level control panel 4 are provided in each cluster-level suppression device.In each cabin level suppression device, one corresponding first cabin level control panel 5 and one second cabin level control panel 6 are provided. Specifically, the first cluster level control panel 3 can communicate with the remote control host 1 CAN. The second cluster level control panel 4 can communicate with the local control host 2 CAN. The first cluster level control panel 3 and the second cluster level control panel 4 may independently control the startup of the cluster level suppression device, or may control the startup of the cluster level suppression device simultaneously. The first cabin level control panel 5 can communicate with the remote control host 1 CAN. The second cabin level control panel 6 can communicate with the local control host 2 CAN. The first cabin level control panel 5 and the second cabin level control panel 6 may independently control the startup of the cabin level suppression device, or may control the startup of the cabin level suppression device simultaneously.

[0025] The first detection device includes a first pack level detector 7 and a first cabin level detector 11. The second detection device includes a second pack level detector 8 and a second cabin level detector 12. Inside each battery pack, one corresponding first pack level detector 7 and one second pack level detector 8 are provided. The first cabin level detector 11 and the second cabin level detector 12 are provided in the battery chamber. The first pack level detector 7 and the second pack level detector 8 are used to detect fire information in the battery pack. The first cabin level detector 11 and the second cabin level detector 12 are used to detect fire information in the battery storage chamber. The first pack level detector 7 and the second pack level detector 8 detect the thermal runaway of the battery pack at an early stage, and by detecting and controlling the thermal runaway at an early stage, the spread of fire is avoided. Also, the first pack level detector 7 and the second pack level detector 8 are redundant with each other. The first cabin level detector 11 and the second cabin level detector 12 are redundant with each other. When any one of the pack level detectors or the cabin level detectors fails, the other one can operate normally, so it has high detection reliability.

[0026] The first pack-level detector 7 in each battery cluster is connected to the first control panel in the cluster-level suppression device corresponding to this battery cluster. The second pack-level detector 8 in each battery cluster is connected to the second control panel in the cluster-level suppression device corresponding to this battery cluster. The first cabin-level detector 11 is connected to the remote control host 1. The second cabin-level detector 12 is connected to the local control host 2. Specifically, the first pack-level detector 7 can perform CAN communication or wireless communication with the first cluster-level control panel 3. The second pack-level detector 8 can perform CAN communication or wireless communication with the second cluster-level control panel 4. When the first pack-level detector 7 and the first cluster-level control panel 3, and the second pack-level detector 8 and the second cluster-level control panel 4 perform CAN communication, the multiple first pack-level detectors 7 in each battery cluster are connected in parallel, and one of the multiple first pack-level detectors 7 is connected to the first cluster-level control panel 3. The multiple second pack-level detectors 8 in each battery cluster are connected in parallel, and one of the multiple second pack-level detectors 8 is connected to the second cluster-level control panel 4. The first cabin-level detector 11 can perform CAN communication or wireless communication with the remote control host 1. The second cabin-level detector 12 can perform CAN communication or wireless communication with the local control host 2. Each cluster-level suppression device receives only the fire information of the corresponding battery cluster. The multiple cluster-level suppression devices do not interfere with each other. The remote control host 1 and the local control host 2 only need to receive the fire information fed back by all the cluster-level suppression devices, as well as the detection information of the first cabin-level detector 11 and the second cabin-level detector 12. The remote control host 1 and the local control host 2 do not need to directly receive the fire information in all the battery packs.

[0027] The remote control host 1 is connected to the local control host 2, and the first control panel is connected to the second control panel. Specifically, the remote control host 1 and the local control host 2 can synchronize data in real time through RS485 communication. The first control panel and the second control panel can exchange information through the internal serial port. Through the information exchange between the remote control host 1 and the local control host 2, and between the first control panel and the second control panel, the present invention realizes the battery pack detection information communication of two paths, namely the first pack level detector - the first cluster level control panel - the remote control host and the second pack level detector - the second cluster level control panel - the local control host. In addition, the present invention can realize two types of communication paths for detection information, namely the first pack level detector - the first cluster level control panel - the second cluster level control panel - the local control host and the second pack level detector - the second cluster level control panel - the first cluster level control panel - the remote control host, thereby improving the reliability of the detection information communication.

[0028] The cluster-level suppression device is connected to a plurality of battery packs via a flow diversion assembly. The flow diversion assembly is used to control the transfer of the fire extinguishing agent to a predetermined battery pack. Specifically, the flow diversion assembly may be a flow diversion valve having a flow diversion function, or a valve assembly composed of a plurality of valves. When the flow diversion assembly is a flow diversion valve, a multi-way flow diversion valve, that is, a flow diversion valve having a plurality of outlet ends and capable of independently controlling the opening and closing of the plurality of outlet ends, can be used. The outlet ends of the flow diversion valve communicate with the battery packs through fire extinguishing pipelines respectively. The fire extinguishing agent flowing out from the cluster-level suppression device enters the flow diversion valve through the inlet end of the flow diversion valve and can enter a predetermined battery pack from a certain outlet end of the flow diversion valve. The flow diversion valve may be electrically connected to a control device or may be electrically connected to a detection device. When the flow diversion valve is electrically connected to the detection device, the flow diversion valve may be electrically connected to the first pack-level detector 7 and the second pack-level detector 8 simultaneously. When the flow diversion assembly is a valve assembly, the valve assembly may be a valve capable of controlling fluid opening and closing, such as a punk valve 10, a ball valve, or a solenoid valve. When it is a punk valve 10, one corresponding punk valve 10 is provided for each battery pack. An inlet passage, an outlet passage, and a mounting passage are provided in the punk valve 10. The space between the inlet passage and the outlet passage is sealed by a film sheet. The outlet passage communicates with the battery pack. A punk mechanism is mounted in the mounting passage. The punk mechanism is used to punch the film sheet. The punk mechanism may be electrically connected to a control device or may be electrically connected to a detection device. When the punk mechanism is electrically connected to the detection device, the punk mechanism may be electrically connected to the first pack-level detector 7 and the second pack-level detector 8 simultaneously. When a fire occurs in the battery pack, the punk mechanism punches the film sheet, so that the inlet passage communicates with the outlet passage, and the fire extinguishing agent of the cluster-level suppression device can enter the interior of the battery pack through the inlet passage-outlet passage. When it is a ball valve or a solenoid valve, one corresponding ball valve or solenoid valve is provided for each battery pack.The fire extinguishing agent of the cluster-level suppression device can flow into the inlet end of the ball valve or solenoid valve and flow into the battery pack from the outlet end of the ball valve or solenoid valve. By only controlling the activation of the ball valve or solenoid valve, the inflow of the fire extinguishing agent into a predetermined battery pack can be realized. The ball valve or solenoid valve may be electrically connected to the control device or may be electrically connected to the detection device. When the ball valve or solenoid valve is electrically connected to the detection device, the ball valve or solenoid valve is simultaneously electrically connected to the first pack-level detector 7 and the second pack-level detector 8.

[0029] The fire suppression device includes a fire extinguishing agent storage tank 15. A cylinder valve 9 is connected to the outlet end of the fire extinguishing agent storage tank 15. A fire extinguishing pipeline is connected to the outlet of the cylinder valve 9. The fire extinguishing pipeline is used to transfer the fire extinguishing agent. The cylinder valve 9 controls whether to release the fire extinguishing agent from the fire extinguishing agent storage tank 15. Specifically, the fire extinguishing agent is stored in the fire extinguishing agent storage tank 15. The fire extinguishing agent storage tank 15 may be a pressure accumulator storage tank. The opening and closing of the cylinder valve 9 can be controlled by the control device. In the present invention, the fire suppression device may be a cluster-level suppression device or a cabin-level suppression device. When it is a cluster-level suppression device, the fire extinguishing pipeline is used to transfer the fire extinguishing agent into the battery pack, and the cylinder valve 9 can be simultaneously electrically connected to the first cluster-level control panel 3 and the second cluster-level control panel 4. When it is a cabin-level suppression device, the fire extinguishing pipeline is used to transfer the fire extinguishing agent into the battery chamber, and the cylinder valve 9 can be simultaneously electrically connected to the first cabin-level control panel 5 and the second cabin-level control panel 6.

[0030] There are multiple fire suppression devices. Each fire suppression device further includes a single direction switching valve 16. The direction switching valve 16 is used to change the transfer direction of the fire extinguishing agent. The direction switching valve 16 is provided in the fire extinguishing pipeline at the outlet end of the cylinder valve 9 of this fire suppression device. The multiple direction switching valves 16 are connected via a connection pipeline. Specifically, the direction switching valve 16 includes at least one liquid inlet end, one liquid outlet end, and one connection end. Here, the liquid inlet end is connected to the outlet end of the cylinder valve 9, the connection end is connected to the connection pipeline, and the liquid outlet end is connected to the fire extinguishing pipeline. The fire extinguishing agent flowing out from the outlet end of the cylinder valve 9 may enter the fire extinguishing pipeline through the liquid inlet end - liquid outlet end, or may enter the connection pipe through the liquid inlet end - connection end. The fire extinguishing agent in the connection pipe may enter the fire extinguishing pipeline through the connection end - liquid outlet end. When the fire suppression device extinguishes a fire, if the amount of the fire extinguishing agent in the fire suppression device is insufficient, the direction of the direction switching valve 16 is switched to activate the cylinder valve 9 of another fire suppression device, and the fire extinguishing agent is made to flow through the connection end - liquid outlet end through the connection pipe and into the fire extinguishing pipeline, thereby ensuring the supply of the fire extinguishing agent. The direction switching valve 16 can be controlled by a control device. In the present invention, the fire suppression device may be a cluster level suppression device or a cabin level suppression device. In the case of a cluster level suppression device, the direction switching valve 16 of the cluster level suppression device is controlled by the first cluster level control panel 3 and / or the second cluster level control panel 4. In the case of a cabin level suppression device, the direction switching valve 16 of the cabin level suppression device is controlled by the first cabin level control panel 5 and / or the second cabin level control panel 6.

[0031] The fire control system further includes an emergency start-stop switch. The emergency start-stop switch is simultaneously connected to the first control device and the second control device. The emergency start-stop switch controls the emergency start of the fire suppression device. The emergency start-stop switch is further provided with an inspection knob switch. When the inspection knob switch is turned on, the fire control system enters the inspection state. Specifically, two emergency start-stop switches may be provided, namely the first emergency start-stop switch 13 and the second emergency start-stop switch 14. The first emergency start-stop switch 13 is provided in the steering cabin of the ship. The second emergency start-stop switch 14 is provided outside the battery room. The first emergency start-stop switch 13 and the second emergency start-stop switch 14 are simultaneously connected to the first control device and the second control device. Further, the first emergency start-stop switch 13 and the second emergency start-stop switch 14 are simultaneously connected to the remote control host 1 and the local control host 2. The emergency start-stop switch includes a control panel. The control panel is provided with an emergency start-stop button and an inspection knob switch. When the emergency start-stop button is pressed, the fire control system starts or stops emergently. When the inspection knob switch is turned on, the fire control system enters the inspection state. The inspection state means that the first control device and the second control device enter the fault detection state, that is, the local control host 2, the remote control host 1, the first cluster-level control panel 3, the second cluster-level control panel 4, the first cabin-level control panel 5 and the second cabin-level control panel 6 enter the fault inspection state. The inspection state further includes the online fault detection of the detection device, that is, artificially changing the gas concentration around the first cabin-level detector 11 and the second cabin-level detector 12, detecting the alarm sensitivity of the first cabin-level detector 11 and the second cabin-level detector 12, and when in the inspection state, the fire suppression device does not start.

[0032] The first control panel and the second control panel are each provided with two control circuits, namely a main control circuit and a backup circuit. When the main control circuit fails, the backup circuit operates. Specifically, the main control circuit and the backup circuit are the same circuit with the same logic and are switched by circuit control. When the main control circuit is operating, the backup circuit does not operate. When the main control circuit fails, it is automatically switched to the backup circuit and operates normally.

[0033] The remote control host 1 and the local control host 2 are each connected to the marine 220V power supply via a charging converter. The remote control host 1 supplies power to the first control panel, and the local control host 2 supplies power to the second control panel. Specifically, the charging converter converts marine AC220V to DC24V. The remote control host 1 supplies power to the first cluster level control panel 3 and the first cabin level control panel 5, and the local control host 2 supplies power to the second cluster level control panel 4 and the second cabin level control panel 6. In addition, the remote control host 1 and the local control host 2 also supply power to the first emergency start-stop switch 13 and the second emergency start-stop switch 14, as well as the first cabin level detector 1 and the second cabin level detector 12. The first cluster level control panel 3 supplies power to the first pack level detector 7, and the second cluster level control panel 4 supplies power to the second pack level detector 8.

[0034] The remote control host 1, the local control host 2, the cluster level suppression device, and the cabin level suppression device are each provided with a backup battery. Specifically, the backup power supply is a DC24V power supply. When the marine 220V power supply fails, the backup power supply supplies power to the remote control host 1, the local control host 2, the first cluster level control panel 3, the second cluster level control panel 4, the first cabin level control panel 5, and the second cabin level control panel 6.

[0035] As shown in FIGS. 1 and 2, when the fire control system is in a normal operating state or when the battery pack undergoes thermal runaway, the present invention performs fire control through a two - path monitoring - control process of the first pack - level detector - the first cluster - level control panel - the remote control host and the second pack - level detector - the second cluster - level control panel - the local control host. Similarly, when a fire occurs in the battery storage room, fire control can also be performed through two paths. Hereinafter, one of the paths will be specifically described as an example. When the battery pack undergoes thermal runaway, the first pack - level detector 7 detects the thermal runaway information and transmits it to the first cluster - level control panel 3. The first cluster - level control panel 3 transmits the thermal runaway information to the remote control host 1, and the remote control host 1 transmits an activation signal according to the thermal runaway information. The first cluster - level control panel 3 receives the activation signal and transmits the activation signal to the first pack - level detector 7. The first pack - level detector 7 receives the activation signal and activates the puncture valve 10, and feeds back the activation state of the puncture valve 10 to the first cluster - level control panel 3. The first cluster - level control panel 3 receives the activation state of the puncture valve 10 and activates the cylinder valve 9, and the fire extinguishing agent is injected into the battery pack. Also, the first cluster - level control panel 3 feeds back the activation state of the fire extinguishing agent to the remote control host 1. When a fire occurs in the battery storage room, the first cabin - level detector 11 detects the fire information and transmits it to the remote control host 1. The remote control host 1 receives the fire information and transmits an activation signal. The first cabin - level control panel 5 receives the activation signal and activates the cylinder valve 9, and the fire extinguishing agent enters the battery storage room to suppress the fire.
