Description

[Technical field]

[0001] The present invention relates to the technical field of marine firefighting, and in particular to a fire protection control system for a marine battery room. [Background technology]

[0002] In recent years, strengthening environmental protection and reducing polluting gas emissions have become a common understanding in countries around the world, and new emission standards are being implemented in many countries one after another. Energy types are gradually being converted from fossil energy to low-carbon energy. Among them, the electric vehicle industry has developed the fastest, and power batteries, one of the core components of electric vehicles, have also made great progress. The application of power batteries has also gradually spread from the electric vehicle industry to other industries. In the field of ships, electric ships equipped with lithium-ion batteries have the advantages of being environmentally friendly, non-polluting, safe, and low-cost to use, and are favored in the shipping industry.

[0003] Electric ships are similar to electric cars in that they use power batteries as a power source, but because ships have a larger driving force and a longer sailing time, the total stored energy of the ship's power battery system is large and the battery system is complex. Therefore, multiple battery clusters are usually provided, and multiple battery packs are provided in each battery cluster. For example, in some electric ships, about 20 battery clusters are provided, and each battery cluster is provided with 10-40 battery packs, and a dedicated cabin (battery room) needs to be provided to arrange them. However, batteries are prone 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, and in severe cases, may even ignite. Battery fires usually have characteristics such as sudden ignition, rapid fire spread, and explosion. If one battery pack goes into thermal runaway, the entire power battery system of the electric ship may go into thermal runaway and cause a fire. In addition, the navigation environment of a ship is significantly different from that on land, and if a fire occurs on a ship in the open sea, rescue by external forces is difficult. Furthermore, compared with battery management systems for automobiles, ship battery management systems are more complex because they are subject to random uncertainties due to factors such as weather, hydrology, waterways, and traffic, as well as frequent fluctuations and large ranges of change in ship load. Therefore, the fire protection control system for ship battery rooms is required to be more reliable than that of electric vehicles, and is further required to be able to perform fire protection control even if a part of the battery management system fails or malfunctions.

[0004] Therefore, how to effectively solve the fire safety problems associated with the large-scale storage and use of lithium batteries on ships, provide a reliable ship battery room fire protection control system, and ensure the safe and reliable operation of electric ships has become an urgent issue that engineers in the relevant technical field need to research.

[Diagram 3] FIG. 2 is a structural schematic diagram of the connection of multiple fire suppression devices of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] As shown in Figs. 1 to 3, in a fire protection 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 protection control system is independent of the battery management system. The fire protection 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 one or more of a temperature sensor, a smoke sensor, a CO sensor, a hydrogen gas sensor, a VOC sensor, a flame sensor, and a CO2 sensor. The detection device can perform a composite judgment of a parameter signal detected by the detection device and transmit it to the control device. For example, the detection device can divide a fire into four levels of alarm, including an incubation period, an early warning period, an alarm period, and an open flame period, according to a parameter range. Among them, in the case of a level 2, 3, or 4 alarm, 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 the battery pack or the battery room. The control device is used to receive a parameter signal transmitted from the detection device, judge and analyze the parameter signal, and transmit an execution command to the fire suppression device. The fire protection control system may further include a voice and light alarm device capable of outputting voice and light alarm information, in which case the control device controls the voice and light 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 to 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 to 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 are used to control whether or not the fire suppression device releases an extinguishing agent. Specifically, the first control device and the second control device may independently control the activation of the fire suppression device, or may simultaneously control the activation of the fire suppression device.In the fire protection control system of the present invention, the detection device and the control device are made redundant, and a two-way monitoring and control process of the detection device-control device-fire suppression device is realized, thereby significantly improving the reliability of the fire protection control system. The fire protection 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 an independent fire protection control system to independently monitor and control fires in the ship battery room, the system provides detection and alarm and fire extinguishing functions even if the ship's battery power fails, without any additional interference or control on the ship's operation safety and the battery power system.

[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 pack of the battery cluster, and the cabin level suppression device is used to inject a fire extinguishing agent into the battery 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 multiple battery clusters. For example, one cluster level suppression device may be provided corresponding to two or three battery clusters. The cluster level suppression device is provided near the corresponding battery cluster so that the fire extinguishing agent in the cluster level suppression device is quickly injected into the ignited battery pack. In the present invention, the battery room is divided into a plurality of areas by dividing the battery cluster into a division unit, and one fire suppression device (cluster level suppression device) is provided corresponding to each divided area. When a battery pack in a battery cluster thermally runs away and ignites, the corresponding cluster-level suppression device can extinguish the battery pack by itself, and the fire suppression device responds quickly to the ignition site. Compared with the conventional method of extinguishing a fire by submerging the room in water in a ship, the fire control system of the present invention can suppress the fire locally before it spreads, thereby reducing damage to the power battery system of the electric ship. Furthermore, the present invention provides a cabin-level suppression device for the battery room. The cabin-level suppression device injects fire extinguishing agent into the entire battery room. If the local fire is suppressed and the fire spreads, the cabin-level suppression device can extinguish the fire.

[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 further have the function of monitoring and displaying the operating status of all the 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 or not the fire suppression device releases a 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 in the fire suppression device. The local control host 2 is provided outside the battery room.

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 in the wheelhouse of the ship. By providing the local control host 2 and the remote control host 1 at different positions on the ship, 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 ease of distinction, the first and second control panels in the cluster level suppression device of the present invention are defined as the first cluster level control panel 3 and the second cluster level control panel 4, and the first and second control panels in the cabin level suppression device are defined as the first cabin level control panel 5 and the second cabin level control panel 6. The first cluster level control panel 3 and the second cluster level control panel 4 are redundant to each other. The first cabin level control panel 5 and the second cabin level control panel 6 are mutually redundant. In each cluster level restraint device, one first cluster level control panel 3 and one second cluster level control panel 4 are provided correspondingly.In each cabin level restraint device, one first cabin level control panel 5 and one second cabin level control panel 6 are provided correspondingly. 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 activation of the cluster level restraint device, or may simultaneously control the activation of the cluster level restraint device. 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 activation of the cabin level restraint device, or may simultaneously control the activation of the cabin level restraint device.

[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. One first pack level detector 7 and one second pack level detector 8 are provided in each battery pack. The first cabin level detector 11 and the second cabin level detector 12 are provided in the battery compartment. 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 compartment. The first pack level detector 7 and the second pack level detector 8 detect thermal runaway of the battery pack early, and by detecting and controlling the thermal runaway early, the spread of the fire is avoided. In addition, the first pack level detector 7 and the second pack level detector 8 are redundant to each other. The first cabin level detector 11 and the second cabin level detector 12 are redundant to each other. If either the pack level detector or the cabin level detector fails, the other can still operate normally, providing 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 the 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 the 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 communicate with the first cluster level control panel 3 via CAN or wireless communication. The second pack level detector 8 can communicate with the second cluster level control panel 4 via CAN or wireless communication. 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 communicate with each other via CAN, the multiple first pack level detectors 7 in each battery cluster are connected in parallel, one of the multiple first pack level detectors 7 is connected to the first cluster level control panel 3, and 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 communicate with the remote control host 1 via CAN or wireless communication. The second cabin level detector 12 can communicate with the local control host 2 via CAN or wireless communication. Each cluster level suppression device receives only the fire information of its corresponding battery cluster. 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 fire information fed back by all cluster level suppression devices and 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 fire information in all battery packs.

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

[0028] The cluster level suppression device is connected to the battery packs via a diversion assembly. The diversion assembly is used to control the transfer of the extinguishing agent to a specific battery pack. Specifically, the diversion assembly may be a diversion valve having a diversion function, or a valve assembly consisting of a plurality of valves. When the diversion assembly is a diversion valve, a multi-way diversion valve, i.e., a diversion valve having a plurality of outlet ends and capable of independently controlling the opening and closing of the plurality of outlet ends, may be used. The outlet ends of the diversion valves are respectively connected to the battery packs by fire extinguishing pipelines. The extinguishing agent flowing out of the cluster level suppression device can enter the diversion valve through the inlet end of the diversion valve and enter a specific battery pack from the outlet end of the diversion valve. The diversion valve may be electrically connected to a control device or may be electrically connected to a detection device. When the diversion valve is electrically connected to the detection device, the diversion valve may be electrically connected to the first pack level detector 7 and the second pack level detector 8 at the same time. When the flow dividing assembly is a valve assembly, the valve assembly may be a valve capable of controlling fluid opening and closing, such as a puncture valve 10, a ball valve, or a solenoid valve. When the puncture valve 10 is used, one puncture valve 10 is provided corresponding to each battery pack. The puncture valve 10 is provided with an inlet passage, an outlet passage, and an attachment passage. The inlet passage and the outlet passage are sealed by a film sheet. The outlet passage communicates with the battery pack. A puncture mechanism is installed in the attachment passage. The puncture mechanism is used to puncture the film sheet. The puncture mechanism may be electrically connected to a control device or may be electrically connected to a detection device. When the puncture mechanism is electrically connected to the detection device, the puncture mechanism may be electrically connected to the first pack level detector 7 and the second pack level detector 8 at the same time. When a fire occurs in the battery pack, the puncture mechanism punctures the film sheet, so that the inlet passage communicates with the outlet passage, and the extinguishing agent of the cluster level suppression device can enter the inside of the battery pack through the inlet passage and the outlet passage. In the case of a ball valve or a solenoid valve, each battery pack is provided with one ball valve or solenoid valve corresponding thereto.The 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 simply controlling the activation of the ball valve or solenoid valve, the extinguishing agent can be realized to flow into a specific battery pack. The ball valve or solenoid valve may be electrically connected to a control device or to a detection device. When the ball valve or solenoid valve is electrically connected to the detection device, the ball valve or solenoid valve is electrically connected to the first pack level detector 7 and the second pack level detector 8 at the same time.

[0029] The fire suppression device includes an extinguishing agent storage tank 15. A cylinder valve 9 is connected to the outlet end of the 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 extinguishing agent. The cylinder valve 9 controls whether to release the extinguishing agent from the extinguishing agent storage tank 15. Specifically, the extinguishing agent is stored in the extinguishing agent storage tank 15. The extinguishing agent storage tank 15 may be a pressure storage tank. The opening and closing of the cylinder valve 9 can be controlled by a control device. It should be noted that 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 extinguishing pipeline is used to transfer the extinguishing agent into the battery pack, and the cylinder valve 9 can be electrically connected to the first cluster level control panel 3 and the second cluster level control panel 4 at the same time. When it is a cabin level suppression device, the fire extinguishing pipeline is used to transport fire extinguishing agent into the battery room, and the cylinder valve 9 can be electrically connected to the first cabin level control panel 5 and the second cabin level control panel 6 at the same time.

[0030] There are a plurality of the fire suppression devices. Each fire suppression device further includes one directional control valve 16. The directional control valve 16 is used to change the transport direction of the extinguishing agent. The directional control valve 16 is provided in the fire extinguishing pipeline at the outlet end of the cylinder valve 9 of the fire suppression device. The plurality of directional control valves 16 are connected through a connecting pipeline. Specifically, the directional control valve 16 includes at least one inlet end, one outlet end and one connecting end. Here, the inlet end is connected to the outlet end of the cylinder valve 9, the connecting end is connected to the connecting pipeline, and the outlet end is connected to the extinguishing pipeline. The extinguishing agent flowing out from the outlet end of the cylinder valve 9 may enter the extinguishing pipeline through the inlet end-outlet end, or may enter the connecting pipe through the inlet end-connecting end. The extinguishing agent in the connecting pipe may enter the extinguishing pipeline through the connecting end-outlet end. When a fire suppression system is extinguishing a fire, if the amount of extinguishing agent in the fire suppression system is insufficient, the direction of the directional control valve 16 is changed to activate the cylinder valve 9 of the other fire suppression system, and the extinguishing agent flows through the connecting pipe from the connection end to the discharge end and into the fire extinguishing pipeline, thereby ensuring the supply of extinguishing agent. The directional control valve 16 can be controlled by a control device. In the present invention, the fire suppression system may be a cluster level suppression system or a cabin level suppression system. If it is a cluster level suppression system, the directional control valve 16 of the cluster level suppression system is controlled by the first cluster level control panel 3 and / or the second cluster level control panel 4. If it is a cabin level suppression system, the directional control valve 16 of the cabin level suppression system is controlled by the first cabin level control panel 5 and / or the second cabin level control panel 6.

[0031] The fire protection 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 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 protection control system is in an inspection state. Specifically, two emergency start / stop switches may be provided, which are a first emergency start / stop switch 13 and a second emergency start / stop switch 14. The first emergency start / stop switch 13 is provided in the wheelhouse 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. Furthermore, 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 protection control system is started or stopped urgently. When the inspection knob switch is turned on, the fire protection control system is in the inspection state. The inspection state includes that the first control device and the second control device are in 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 are in the fault inspection state. The inspection state further includes the online fault detection of the detection device, that is, the gas concentration around the first cabin level detector 11 and the second cabin level detector 12 is artificially changed to detect the alarm sensitivity of the first cabin level detector 11 and the second cabin level detector 12, and the fire suppression device is not activated when in the inspection state.

[0032] The first and second control panels are each provided with two control circuits, a main control circuit and a backup circuit. If 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, and if the main control circuit fails, it automatically switches to the backup circuit and operates normally.

[0033] The remote control host 1 and the local control host 2 are each connected to a ship 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 ship AC 220V to DC 24V. 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. 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, and 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 source is a DC 24V power source. In the event of a failure of the ship's 220V power source, the backup power source 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 FIG. 1 and FIG. 2, when the fire control system is in a normal operating state, if the battery pack goes into thermal runaway, the present invention performs fire control by a monitoring-control process of two routes: 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, if a fire occurs in the battery room, fire control can be performed by two routes. Hereinafter, one of the routes will be specifically described as an example. When the battery pack goes into thermal runaway, the first pack level detector 7 detects 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 in response 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 status of the puncture valve 10 and activates the cylinder valve 9, and the extinguishing agent is injected into the battery pack. The first cluster level control panel 3 also feeds back the activation status of the extinguishing agent to the remote control host 1. When a fire breaks out in the battery room, the first cabin level detector 11 detects the fire information and transmits it to the remote control host 1.
