DETAILED DESCRIPTION

[0046] First, those skilled in the art should understand that the embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust them as needed to adapt to specific application occasions.

[0047] Secondly, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0048] Then, it also needs to be explained that in the description of the present application, the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and is not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0049] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.

[0050] As shown in the background, the roll-on / roll-off ship, also known as roll-on / roll-off cargo ship or roll-on / roll-off transport ship, is a ship specially used for transporting vehicles and other wheeled cargo. The cargo hold of the roll-on / roll-off ship is usually without transverse bulkhead, forming a long rectangular space, so as to have a large open cargo hold, facilitating the free entry and flexible parking of vehicles.

[0051] In the prior art, a plurality of nozzles are uniformly arranged on the top of the cargo hold, and a steel cylinder group is arranged on the roll-on / roll-off ship. The steel cylinder group is used for storing high-pressure liquid carbon dioxide, and is connected with the nozzles through pipelines. When a fire occurs, the steel cylinder valve is opened, and the liquid carbon dioxide is transported to the nozzles on the top of the cargo hold through the pipelines. The nozzles atomize and uniformly spray the carbon dioxide, which diffuses to the entire cargo hold space, reducing the oxygen concentration, so as to suffocate the flame.

[0052] However, the cargo hold space is large, and it takes a long time for the carbon dioxide to diffuse to the entire cargo hold space, resulting in low fire extinguishing efficiency, and a large amount of carbon dioxide is consumed, causing waste.

[0053] Based on this, the present application provides a fire extinguishing system, a roll-on / roll-off ship, and a fire extinguishing method. The fire extinguishing system is applied to a cargo ship. The fire extinguishing system is provided by providing multiple isolation components and multiple fire extinguishing components. Each isolation component is sequentially arranged on the cargo ship to separate the cargo ship into multiple fire zones. Each fire extinguishing component is correspondingly arranged in each fire zone. When a fire occurs in a fire zone, the fire extinguishing component in that fire zone can provide a fire extinguishing medium. Because the isolation components divide the larger cargo hold space of the cargo ship into smaller fire zones, the time required for the fire extinguishing medium to diffuse throughout the fire zone is shortened, thereby improving fire extinguishing efficiency.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] Reference Figure 1 As shown, the fire extinguishing system provided in the present application is applied to a cargo ship, and includes: a plurality of isolation components 100 and a plurality of fire extinguishing components 200, each isolation component 100 is used to be arranged in sequence on the cargo ship to separate the cargo ship into a plurality of fire zones 11.

[0056] Each fire extinguishing assembly 200 is correspondingly arranged in each fire protection zone 11 , and the fire extinguishing assembly 200 is used to provide a fire extinguishing medium when a fire occurs in the corresponding fire protection zone 11 .

[0057] It should be noted that the fire extinguishing system provided in this embodiment is applied to cargo ships, including but not limited to roll-on / roll-off ships and container ships. This application uses roll-on / roll-off ships as an example to illustrate the fire extinguishing system.

[0058] Specifically, it can be along the length direction of the cargo hold of the ro-ro ship ( Figure 1 In the X direction as indicated by the middle arrow), a plurality of isolation assemblies 100 are sequentially arranged at intervals to separate the through cargo hold into a plurality of fire zones 11. When a fire occurs in a certain fire zone 11, the isolation assembly 100 can prevent the fire from spreading to other fire zones 11, thereby improving safety.

[0059] Then, by setting the fire extinguishing assembly 200 in each fireproof area 11, when a fire occurs in a certain fireproof area 11, the fire extinguishing assembly 200 in the fireproof area 11 can provide fire extinguishing medium. Because the isolation assembly 100 divides the larger cargo hold space into smaller fireproof areas 11, the time required for the fire extinguishing medium to diffuse to the entire fireproof area 11 is shorter, and the fire extinguishing efficiency is improved. At the same time, the fireproof area 11 is small in space, and less fire extinguishing medium is consumed, reducing waste.

[0060] It should be noted that the roll-on / roll-off ship has multiple layers of cargo holds, and multiple isolation assemblies 100 can be arranged in each layer of the cargo hold of the roll-on / roll-off ship to divide each layer of the cargo hold into multiple fireproof areas 11.

[0061] In specific implementation, one fire extinguishing assembly 200 can be arranged in each fireproof area 11; two fire extinguishing assemblies 200 can also be arranged in each fireproof area 11, and the two fire extinguishing assemblies 200 are symmetrically arranged on opposite sides of the fireproof area 11; or more than two fire extinguishing assemblies 200 can be arranged in each fireproof area 11, and the fire extinguishing assemblies 200 are arranged at intervals in the fireproof area 11.

[0062] Exemplarily, the fire extinguishing medium can be carbon dioxide, can be fire extinguishing foam, can be perfluorohexone, or can be fire-fighting water. In specific implementation, a suitable fire extinguishing medium can be selected according to the type of fire, and the embodiments of the present application do not make too many limitations in this regard.

[0063] In some embodiments, referring to Figures 1 to 4 It is shown that the isolation assembly 100 includes a guide 110 and an isolation piece 120, and the isolation piece 120 is slidingly connected to the guide 110 to isolate or connect two adjacent fireproof areas 11.

[0064] It should be noted that when it is necessary to load the vehicle 15 into the cargo hold of the roll-on / roll-off ship, the isolation piece 120 is driven to slide relative to the guide 110 in a first direction to connect two adjacent fireproof areas 11, thereby facilitating the vehicle 15 to travel and flexibly park on the deck 12, and quickly complete the loading.

[0065] After the vehicle 15 is fully loaded, the isolation piece 120 is driven to slide relative to the guide 110 in a second direction (the second direction is opposite to the first direction) to isolate two adjacent fireproof areas 11, thereby forming a protection area. The fire extinguishing medium provided by the fire extinguishing assembly 200 only diffuses in the corresponding fireproof area 11 and does not diffuse across the isolation piece 120, so that the fire extinguishing medium can quickly cover the entire fireproof area 11, thereby improving the fire extinguishing efficiency.

[0066] In specific implementation, the guide 110 and the isolation piece 120 are made of high-temperature-resistant and fire-resistant materials.

[0067] In some embodiments, referring to Figure 2 andFigure 3 As shown, the guide 110 is arranged on the ceiling 14 or deck 12 of the cargo ship, and the guide 110 extends from one side of the ceiling 14 or deck 12 to the other side.

[0068] In a specific implementation, the guide 110 can be a guide rail.

[0069] For example, referring to Figure 2 As shown, the guide rail can be welded or bolted on the ceiling 14 of the roll-on / roll-off ship, and the isolation member 120 can be a high-temperature-resistant and fire-resistant soft material, such as a fire-retardant PVC fire curtain. The isolation member 120 can be slidably connected to the guide rail by a hook or a lifting ring, and the guide rail provides support, guidance, and limiting functions for the isolation member 120. The isolation member 120 can be operated like a curtain, and can be pulled from the center of the cargo hold to the two sides of the cargo hold to achieve the connection between the two adjacent fireproof areas 11, or can be pulled from the two sides of the cargo hold to the center to achieve the isolation between the two adjacent fireproof areas 11.

[0070] For example, referring to Figure 3 As shown, the guide rail can be welded or bolted on the deck 12 of the roll-on / roll-off ship, and the isolation member 120 can be a high-temperature-resistant and fire-resistant hard material. The structure of the isolation member 120 is similar to an organ type structure, such as a corrugated structure woven by aluminum oxide / aluminum silicate fibers, and the surface is coated with a high-temperature-resistant coating (such as silicone or ceramic slurry). The isolation member 120 can be slidably connected to the guide rail by a sliding groove, and the isolation member 120 can also be pulled from the center of the cargo hold to the two sides of the cargo hold to achieve the connection between the two adjacent fireproof areas 11, or can be pulled from the two sides of the cargo hold to the center to achieve the isolation between the two adjacent fireproof areas 11.

[0071] In some embodiments, referring to Figure 4 As shown, the isolation assembly 100 further includes a rotating member 130, and the two ends of the rotating member 130 are respectively connected to the two cargo hold uprights 13 or two side walls of the cargo ship, and the rotating member 130 is located at the top of the cargo hold uprights 13 or side walls, and at least part of the isolation member 120 is arranged around the rotating member 130.

[0072] The guide 110 is arranged on one of the two cargo hold uprights 13 or two side walls, and the extension direction of the guide 110 is consistent with the height direction of the cargo hold uprights 13 or side walls. The rotating member 130 rotates along its own axis to drive part of the isolation member 120 to slide relative to the guide 110.

[0073] For example, the rotating member 130 can be a rotating shaft. Specifically, the rotating member 130 is located at the top of the cargo hold uprights 13 or side walls, and at least part of the isolation member 120 is arranged around the rotating member 130. The rotating member 130 rotates along its own axis, and can retract or release part of the isolation member 120.

[0074] Since the extending direction of the guide 110 is consistent with the height direction of the cabin column 13 or the side wall, the isolation member 120 is slidingly connected to the guide 110, and the guide 110 can support, guide and limit the isolation member 120. When the rotating member 130 retracts part of the isolation member 120, the guide 110 can guide the isolation member 120 to rise (i.e., slide along the positive direction of Z indicated by the arrow in the middle of the figure); when the rotating member 130 releases part of the isolation member 120, the guide 110 can guide the isolation member 120 to descend (i.e., slide along the negative direction of Z indicated by the arrow in the middle of the figure). Figure 4 Figure 4

[0075] In some embodiments, as shown in Figure 4 , the isolation assembly 100 further comprises a driving member 140, which is arranged on the guide 110, and the driving member 140 is connected to the isolation member 120, and the driving member 140 drives the isolation member 120 to slide relative to the guide 110.

[0076] In a specific implementation, the driving member 140 can be a motor, and the guide 110 can be a guide rail, and a trolley is arranged in the guide rail, and the guide rail is connected to the isolation member 120 through the trolley. The motor can be installed at one end of the guide rail, and the motor drives the trolley in the guide rail to move through a belt (synchronous belt), thereby pulling the isolation member 120 to slide. The motor is used to electrically control the displacement of the isolation member 120, which is convenient to operate and saves manpower.

[0077] In some embodiments, the trigger condition for starting the driving member 140 can be set as whether the vehicle 15 is fully loaded, that is, when the vehicle 15 needs to be loaded, the driving member 140 is started to control the isolation member 120 to connect the two adjacent fireproof areas 11, so as to facilitate the vehicle 15 to travel and flexibly park on the deck 12; after the vehicle 15 is fully loaded, the driving member 140 is started to control the isolation member 120 to isolate the two adjacent fireproof areas 11.

[0078] In some embodiments, the trigger condition for starting the driving member 140 can also be set as whether a fire occurs, that is, when no fire occurs, the two adjacent fireproof areas 11 are connected, and when a fire occurs, the driving member 140 is started to control the isolation member 120 to isolate the two adjacent fireproof areas 11.

[0079] In some embodiments, as shown in Figure 5 , the fire extinguishing assembly 200 comprises a storage member 210 and a generating member 220 connected to the storage member 210, the storage member 210 is used to store medium raw materials, and the generating member 220 is used to change the medium raw materials into fire extinguishing medium and provide the fire extinguishing medium for the corresponding fireproof area 11.

[0080] ​​Specifically, the liquid storage member 210 is directly connected with the generating member 220, and the generating member 220 can quickly provide the fire extinguishing medium for the corresponding fireproof area 11 for fire extinguishing operation.

[0081] It should be noted that the steel cylinder group in the prior art is arranged in a special cabin of the roll-on / roll-off ship, and is connected with the nozzle in the cargo hold through a long pipeline. The transportation time of the carbon dioxide in the pipeline is relatively long. The fire extinguishing assembly 200 in the embodiment of the present application is arranged in the fireproof area 11, that is, the liquid storage member 210 and the generating member 220 are arranged in the fireproof area 11, thereby reducing the connecting pipeline between the liquid storage member 210 and the generating member 220, reducing the transportation time of the medium raw material in the pipeline, and providing the fire extinguishing medium in time and stably, thereby improving the fire extinguishing efficiency.

[0082] It should be further noted that in the prior art, the fire extinguishing medium has a certain erosion effect on the pipeline. After use or long-term idling, the pipeline needs to be cleaned and maintained, which consumes a large amount of manpower and resource cost. The liquid storage member 210 of the fire extinguishing assembly 200 is connected with the generating member 220, thereby reducing the connecting pipeline and the maintenance cost.

[0083] Exemplarily, the liquid storage member 210 can be a liquid storage tank, a liquid storage barrel or a liquid storage bottle, and the generating member 220 can be a spray head. The medium raw material in the liquid storage member 210 can be high-pressure liquid carbon dioxide, and the fire extinguishing medium sprayed out of the generating member 220 is gaseous carbon dioxide. The medium raw material in the liquid storage member 210 can also be perfluorohexanone (liquid), and the fire extinguishing medium sprayed out of the generating member 220 is perfluorohexanone (micro liquid droplets).

[0084] It should be noted that the generating member 220 sprays the micro liquid droplets of perfluorohexanone into the fireproof area 11. The perfluorohexanone will rapidly vaporize and diffuse to the entire fireproof area 11, reducing the oxygen concentration and blocking the combustion. The perfluorohexanone liquid droplets also absorb a large amount of heat in the vaporization process, reducing the temperature in the fireproof area 11 and improving the fire extinguishing efficiency.

[0085] In some embodiments, referring to FIG. 2, the fire extinguishing assembly 200 further includes a fire hydrant 230 and a proportional mixing member 240. The proportional mixing member 240 is connected between the liquid storage member 210 and the generating member 220. The fire hydrant 230 is connected with the proportional mixing member 240. The fire hydrant 230 is used to provide fire-fighting water, and the proportional mixing member 240 is used to adjust the proportion of the medium raw material and the fire-fighting water. Figure 5

[0086] ​In a specific implementation, the proportional mixing component 240 has a first input interface 241, a second input interface 242, and an output interface 243. The first input interface 241 is configured to be connected to the fire hydrant 230, and the fire hydrant 230 is configured to provide fire water. The first input interface 241 is configured to be connected to the storage component 210, and the storage component 210 is configured to provide the medium raw material. The output interface 243 is configured to be connected to the generating component 220. The medium raw material and the fire water are mixed by the proportional mixing component 240, and then input into the generating component 220. The generating component 220 outputs the fire extinguishing medium.

[0087] For example, the proportional mixing component 240 can be a proportional mixer, the generating component 220 can be a foam generator, and the medium raw material can be foam raw liquid. The valves on the first input interface 241 and the second input interface 242 are opened. The fire hydrant 230 and the storage component 210 respectively deliver fire water and foam raw liquid to the proportional mixing component 240. The proportional mixing component 240 mixes the foam raw liquid and the fire water, and then delivers the mixture to the generating component 220 through the output interface 243. The generating component 220 changes the mixture into fire extinguishing foam, which is used to cover the fire site, so as to achieve the effect of fire extinguishing.

[0088] In some embodiments, the medium raw material is perfluorohexanone, carbon dioxide, or foam raw liquid.

[0089] In a specific implementation, whether the medium raw material is mixed with the fire water by the proportional mixing component 240 can be selected according to the type of the fire extinguishing raw material used.

[0090] For example, when the medium raw material is perfluorohexanone or carbon dioxide, the valve on the first input interface 241 can be closed, and the valve on the second input interface 242 can be opened. The storage component 210 delivers perfluorohexanone or carbon dioxide to the proportional mixing component 240. The proportional mixing component 240 delivers perfluorohexanone or carbon dioxide to the generating component 220 through the output interface 243. The generating component 220 provides perfluorohexanone or carbon dioxide for fire extinguishing in the fireproof area 11.

[0091] For example, when the medium raw material is foam raw liquid, the valves on the first input interface 241 and the second input interface 242 can be opened simultaneously. The fire hydrant 230 and the storage component 210 respectively deliver fire water and foam raw liquid to the proportional mixing component 240. The proportional mixing component 240 mixes the foam raw liquid and the fire water, and then delivers the mixture to the generating component 220 through the output interface 243. The generating component 220 changes the mixture into fire extinguishing foam for fire extinguishing. In a specific implementation, the proportion of the fire water and the foam raw liquid can be controlled by adjusting the opening range of the valves on the first input interface 241 and the second input interface 242.

[0092] It should be noted that two fire extinguishing assemblies 200 can be provided in the same fireproof area 11 at the same time, the first fire extinguishing assembly 200 stores the foam raw liquid in the liquid storage member 210, and the second fire extinguishing assembly 200 stores carbon dioxide in the liquid storage member 210. When the fire starts, the first fire extinguishing assembly 200 provides fire extinguishing foam for the fireproof area 11 where the fire occurs to quickly extinguish the fire. After the open fire is extinguished, the second fire extinguishing assembly 200 provides carbon dioxide, which covers the entire fireproof area 11, so as to maintain a low-oxygen environment in the fireproof area 11 and prevent rekindling, thereby improving the reliability of fire extinguishing.

[0093] In some embodiments, referring to Figure 6 The fire extinguishing assembly 200 further comprises a connecting member 250, the connecting member 250 is arranged on the ceiling 14 of the cargo ship, and the generating member 220 is connected to the connecting member 250.

[0094] Exemplarily, one end of the connecting member 250 can be welded or bolted to the ceiling 14, and the other end of the connecting member 250 can be provided with a socket, and the generating member 220 is inserted into the socket. Thus, the connecting member 250 fixes the generating member 220, prevents the generating member 220 from being separated from the proportional mixing member 240, and improves the reliability of the fire extinguishing assembly 200.

[0095] It should be noted that the outlet of the generating member 220 can be vertically downward (i.e., in the direction opposite to Z shown by the arrow in Figure 6 It should be noted that the outlet of the generating member 220 can be vertically downward (i.e., in the direction opposite to Z shown by the arrow in Figure 5 The two setting modes can cover the fireproof area 11 with fire extinguishing medium, and the embodiments of the present application do not make too many limitations.

[0096] In some embodiments, referring to Figure 6 The fire extinguishing system further comprises a plurality of first detection members 300 and a plurality of control members, each first detection member 300 and each control member are correspondingly arranged in each fireproof area 11.

[0097] The first detection member 300 is used for detecting whether the corresponding fireproof area 11 has a fire.

[0098] The first detection member 300, the isolation assembly 100 and the fire extinguishing assembly 200 are in communication connection with the corresponding control member. When the first detection member 300 detects that the fireproof area 11 has a fire, the control member controls the corresponding isolation assembly 100 to isolate the adjacent two fireproof areas 11, and controls the corresponding fire extinguishing assembly 200 to provide fire extinguishing medium for the fireproof area 11.

[0099] Specifically, when the first detection member 300 detects a fire in the fireproof area 11, the first detection member 300 transmits a signal of the fire to the controller, and the controller controls the corresponding isolation assembly 100 to isolate the adjacent two fireproof areas 11, preventing the fire from spreading to other fireproof areas 11, thereby improving the safety. Moreover, the controller controls the corresponding fire extinguishing assembly 200 to provide fire extinguishing medium, and the fire extinguishing medium can quickly cover the entire fireproof area 11, thereby improving the fire extinguishing efficiency.

[0100] It should be noted that by setting the first detection member 300 to monitor in real time, the fire information can be sent to the controller at the initial stage of the fire, and the controller controls the isolation assembly 100 and the fire extinguishing assembly 200 in time, reduces the delay caused by human factors, and avoids the expansion of the fire.

[0101] In some embodiments, referring to Figure 6 , the first detection member 300 is at least one of an infrared thermal imager and a smoke sensor.

[0102] It should be noted that the infrared thermal imager detects fire by detecting infrared radiation (heat) on the surface of an object. It converts invisible heat energy into a visual temperature distribution image using an infrared detector, and can detect high-temperature hazards at the initial stage of a fire (before visible flames or smoke are generated). It is especially suitable for identifying hidden fire sources such as overheating of vehicle 15 batteries and electrical short circuits, and can accurately locate the fire point, providing key information for early fire extinguishing.

[0103] It should also be noted that the smoke sensor identifies fire by detecting specific gases (such as carbon monoxide, carbon dioxide, or volatile organic compounds) released during combustion. When combustible materials burn, they will produce characteristic gases, and the chemical or physical detection elements (such as semiconductors, electrochemical, or infrared modules) inside the sensor can sense the abnormal increase in gas concentration. Compared with traditional smoke sensors, it can detect hidden fires or fires without visible smoke (such as gases released during the initial stage of lithium battery thermal runaway) earlier, and is suitable for early fire warning in complex environments.

[0104] In some embodiments, referring to Figure 6 , the fire extinguishing system further comprises a plurality of second detection members 400, each second detection member 400 being correspondingly arranged in each fireproof area 11.

[0105] The second detection member 400 is in communication connection with the vehicle-mounted alarm system of the vehicle 15 in the corresponding fireproof area 11, and the second detection member 400 is used to detect whether the corresponding vehicle-mounted alarm system sends an alarm signal.

[0106] The second detection member 400 is in communication connection with the corresponding control member. When the second detection member 400 detects that the vehicle alarm system sends an alarm signal, the control member controls the corresponding isolation assembly 100 to isolate the adjacent two fireproof areas 11, and controls the fire extinguishing assembly 200 to provide fire extinguishing medium for the corresponding fireproof area 11.

[0107] Specifically, the second detection member 400 can accept the alarm signal sent by the vehicle alarm system. It should be noted that the vehicle alarm system can monitor the temperature, working state and other information of the battery of the vehicle 15. When the battery of the vehicle 15 is abnormal, the vehicle alarm system can detect the battery abnormal information in time and send an alarm signal to the second detection member 400.

[0108] Referring to Figure 7 As shown in the figure, a plurality of virtual parking spaces 16 can be divided in each fireproof area 11 of the roll-on / roll-off ship. All real parking spaces for parking vehicles 15 on the roll-on / roll-off ship correspond to the virtual parking spaces 16 one by one. When a vehicle 15 is parked in the corresponding virtual parking space 16, the unique identification code of the vehicle 15 is scanned and acquired. The unique identification code can be the vehicle identification number (VIN code) of the vehicle 15 or other identification information that can distinguish the vehicle 15 from other vehicles 15. Through this means, the vehicle 15 information parked in the virtual parking space 16 can be bound to the virtual parking space 16. At this time, the unique identification code of each vehicle 15 parked on the roll-on / roll-off ship can be bound to the corresponding position area of the actual parking location of the vehicle 15 on the roll-on / roll-off ship. When the vehicle alarm system of the vehicle 15 sends an alarm signal, the unique identification code information of the vehicle 15 will be attached. According to the binding of the unique identification code information of the vehicle 15 attached to the alarm signal received by the second detection member 400 and the virtual parking space 16, the accurate position of the vehicle 15 with fault can be known, and the positioning function of the vehicle 15 with fault can be realized.

[0109] The fire extinguishing assembly 200 in the fireproof area 11 and the second detection member 400 are in communication connection with the controller. When the battery pack of the vehicle 15 is abnormal, an alarm signal will be sent. When the second detection member 400 of the fireproof area 11 detects that the vehicle alarm system of the vehicle 15 sends an alarm signal, the fire extinguishing assembly 200 in the fireproof area 11 will immediately start working and generate a large amount of fire extinguishing medium in a short time to quickly cover the entire fireproof area 11. The generated fire extinguishing medium can quickly fill the gap between the vehicles 15 and cover the battery pack at the bottom of the vehicle 15 to achieve the effect of fire extinguishing and cooling. When the vehicle 15 with fault is on fire, the surrounding vehicles 15 can be prevented from being on fire due to heat diffusion and fire spread, the fire spread can be effectively suppressed, and the fire spread chain can be blocked.

[0110] It should be noted that, referring to Figure 8As shown, the virtual parking space 16 may not be limited to a single vehicle 15 parking space. A large virtual parking space 16 may be set within the entire fire protection zone 11. When the second detection component 400 receives the unique identification code information carried by the alarm signal emitted by the faulty vehicle 15 in the large virtual parking space 16, the fire extinguishing component 200 in the protection area where the large virtual parking space 16 is located can be activated, thereby realizing the linkage between the virtual parking space 16 positioning system and the fire extinguishing component 200.

[0111] The present application also provides a roll-on / roll-off ship, comprising a roll-on / roll-off ship body 10 and a fire extinguishing system arranged on the roll-on / roll-off ship body 10 .

[0112] The specific structure and working mode of the fire extinguishing system are described in detail in the above embodiments and will not be repeated here.

[0113] It should be noted that the ro-ro ship body 10 is the main body, including the hull, deck 12 and ship wall.

[0114] Reference Figure 9 As shown, the present application also provides a fire extinguishing method, using a fire extinguishing system, the fire extinguishing method includes:

[0115] S101 , using the isolation components 100 of the fire extinguishing system to separate the cargo ship into multiple fire zones 11 .

[0116] Specifically, a plurality of isolation assemblies 100 can be arranged in sequence and spaced apart along the length direction of the cargo hold of the roll-on / roll-off ship to divide the through cargo hold into a plurality of fire zones 11. When a fire occurs in a certain fire zone 11, the isolation assembly 100 can prevent the fire from spreading to other fire zones 11, thereby improving safety.

[0117] S102: When a fire occurs in the fire protection zone 11, the corresponding fire extinguishing component 200 of the fire extinguishing system provides a fire extinguishing medium.

[0118] Specifically, by installing a fire extinguishing assembly 200 in each fire zone 11, when a fire occurs in a particular fire zone 11, the fire extinguishing assembly 200 in that fire zone 11 can provide fire extinguishing medium. Because the partition assembly 100 divides the larger cargo hold space into smaller fire zones 11, the time required for the fire extinguishing medium to spread throughout the fire zones 11 is shortened, improving fire extinguishing efficiency. Furthermore, the smaller fire zones 11 consume less fire extinguishing medium, reducing waste.

[0119] Those skilled in the art can understand that the fire extinguishing system, the roll-on / roll-off ship and the fire extinguishing method provided by the present application, the fire extinguishing system is applied to a cargo ship, the fire extinguishing system is provided with a plurality of isolation assemblies 100 and a plurality of fire extinguishing assemblies 200, each isolation assembly 100 is arranged on the cargo ship in sequence to divide the cargo ship into a plurality of fireproof areas 11. Each fire extinguishing assembly 200 is arranged in each fireproof area 11, and when a fire occurs in a certain fireproof area 11, the fire extinguishing assembly 200 in the fireproof area 11 can provide fire extinguishing medium. Because the isolation assembly 100 divides the large cargo hold space of the cargo ship into smaller fireproof areas 11, the time required for the fire extinguishing medium to diffuse to the entire fireproof area 11 is shorter, and the fire extinguishing efficiency is improved.
