[0041] The present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0042] In order to prevent fire from occurring on the ship 1, a fire extinguishing system 2 is provided on the existing ship 1. The fire extinguishing system 2 generally includes: a fire extinguishing main pipe 221, a fire main control valve 242, a fire extinguishing pump 241 and a seawater tank 21. The seawater tank 21 is located at the bottom of the ship 1. The seawater tank 21 is connected to seawater through a pipeline. The fire extinguishing pump 241 and the fire main control valve 242 are located on the pipeline connecting the seawater tank 21 and the fire extinguishing main pipe 221. When a fire occurs on the ship 1, the fire main control valve 242 and the fire extinguishing pump 241 can be opened to extinguish the fire in the seawater tank 21. The fire extinguishing medium is pumped to the fire extinguishing main pipe 221. At the same time, the fire extinguishing water gun and the fire hose are connected to the fire extinguishing system 2 to extinguish the fire in the area where the fire occurs on the ship 1. However, the fire extinguishing system 2 currently installed is generally installed in the bow area 11 and the stern area 12 of the ship 1, which can achieve relatively dispersed fire extinguishing locations. In addition, when a fire occurs, it is necessary to wait for the fire extinguishing water gun and the fire hose to be connected to the fire extinguishing system 2 before the fire can be extinguished. The connection process is time-consuming and laborious, and due to the length of the fire hose, some locations are difficult to reach, and the efficiency of handling the fire is greatly reduced.

[0043] To solve the above problems, the present disclosure provides a fire extinguishing system 2, such as Figures 1 to 4 As shown, the fire extinguishing system 2 is arranged on the ship 1. The ship 1 has a bow area 11, a stern area 12 and multiple cargo hold areas 13. The cargo hold area 13 is located between the bow area 11 and the stern area 12. The fire extinguishing system 2 may include: a fire extinguishing module 22, a sprinkler module 23 and a seawater tank 21.

[0044] Specifically, the seawater tank 21 is located at the bottom of the ship 1, and the seawater tank 21 is connected to seawater. The fire extinguishing system 2 includes a sea valve 213. The sea valve 213 is arranged in the pipeline connecting the seawater tank 21 to the seawater to control the fire extinguishing medium to enter the seawater tank 21. By setting the seawater tank 21, seawater can be pumped into the seawater tank 21. Seawater is used as a fire extinguishing medium. When a fire occurs in the ship 1, seawater can be pumped at any time, thereby ensuring that the fire extinguishing system 2 has sufficient fire extinguishing medium to extinguish the fire of the ship 1, so as to improve the safety of the ship 1. At the same time, using seawater as a fire extinguishing medium can save the use cost of the fire extinguishing system 2. In addition, in order to avoid overweight of the ship 1, the fire extinguishing medium stored in the seawater tank 21 can be reduced to reduce the load of the ship 1, so as to avoid the problem of capsizing of the ship 1 due to overweight, thereby improving the safety of the operation of the ship 1 and the navigation ability of the ship 1.

[0045] In addition, the seawater tank 21 may include a coarse filter 214, which is disposed in the connecting pipeline between the seawater tank 21 and the fire extinguishing module 22, to filter impurities in the seawater, to prevent impurities from entering the fire extinguishing system 2 and causing the pipeline in the fire extinguishing system 2 to be blocked, and to reduce the pollution of the ship 1 by impurities, thereby extending the service life of the fire extinguishing system 2, reducing the maintenance cost of the fire extinguishing system 2 and the cleaning cost of the ship 1, and at the same time, ensuring the normal operation of the fire extinguishing system 2, which can improve the safety performance of the ship 1 and improve the reliability of container cargo transportation. However, it is not limited to this, the coarse filter 214 can also be disposed in the pipeline connecting the seawater tank 21 to the seawater, and the seawater can filter out impurities in the seawater entering the seawater tank 21 through the coarse filter 214, to prevent the impurities in the seawater from accumulating in the seawater tank 21.

[0046] The fire extinguishing module 22 is connected to the seawater tank 21 to obtain the fire extinguishing medium in the seawater tank 21. The fire extinguishing module 22 includes a fire extinguishing main pipe 221. The fire extinguishing main pipe 221 is arranged in the bow area 11, the stern area 12 and each cargo hold area 13. The fire extinguishing medium enters the fire extinguishing module 22 from the seawater tank 21 and flows on the fire extinguishing main pipe 221. Through the fire extinguishing main pipe 221, the fire extinguishing medium can be provided to each area of ​​the fire extinguishing module 22. When a fire occurs, fire extinguishing devices such as fire hoses and fire hoses can be connected to the fire extinguishing module 22, so as to realize local spray fire extinguishing of the ship 1.

[0047] It should be noted that an expansion joint 222 may be provided on the fire extinguishing main pipe 221 , and the expansion joint 222 may be used to absorb the expansion of the fire extinguishing main pipe 221 to avoid leakage, bending or rupture of the fire extinguishing main pipe 221 .

[0048] In order to solve the problem that the connection between the fire extinguishing devices such as fire hoses and fire hoses and the fire extinguishing module 22 in the existing ship 1 is time-consuming and labor-intensive, and the problem that the fire hose is limited in length and difficult to reach some locations on the ship 1, the embodiment of the present disclosure is provided with a sprinkler module 23 in the fire extinguishing system 2, such as Figure 2 As shown, the spray module 23 includes multiple nozzles 232 and multiple spray pipes 231. Each spray pipe 231 is provided with multiple nozzles 232. The spray pipe 231 is connected to the fire extinguishing main pipe 221, so that the fire extinguishing medium in the fire extinguishing main pipe 221 can enter the spray module 23.

[0049] It should be noted that the spray pipe 231 and the nozzle 232 in the embodiment of the present disclosure are arranged in each cargo hold area 13, and the nozzle 232 and the spray pipe 231 are arranged around the cargo hold area 13 (such as Figure 3 and Figure 4 shown).

[0050] Specifically, each cargo hold area 13 is provided with a sprinkler pipe 231 and a nozzle 232. The sprinkler pipe 231 is located at the top of the cargo hold area 13, and the sprinkler pipe 231 in each cargo hold area 13 is arranged around the cargo hold area 13 where it is located. Each sprinkler pipe 231 is connected to a plurality of nozzles 232. When the fire extinguishing medium enters the sprinkler pipe 231, the fire extinguishing medium is atomized through the nozzle 232, thereby increasing the contact area between the fire extinguishing medium and the fire area, and realizing water curtain fire extinguishing of the cargo hold area 13, so as to improve the fire extinguishing efficiency of the cargo hold area 13.

[0051] In the disclosed embodiment, the number of nozzles 232 provided in each cargo hold area 13 may not be equal, and the specific number of nozzles 232 provided may be determined based on the actual area of ​​the cargo hold area 13, the required amount of water, the flow rate of a single nozzle 232, etc.

[0052] A ball valve with a hose connector 233 may be provided on the spray pipeline 231. Specifically, the ball valve with a hose connector 233 may be located at one end of the control valve 234 close to the nozzle 232. An external pipeline may be connected to the ball valve with a hose connector 233 to access a cleaning medium to clean the spray pipeline 231 and the nozzle 232, thereby keeping the spray pipeline 231 and the nozzle 232 clean and preventing the spray pipeline 231 and the nozzle 232 from being blocked. This may improve the service life of the fire extinguishing system 2 and the safety and reliability of the ship 1, and reduce the cleaning cost of the ship 1.

[0053] The embodiment of the present disclosure sets a sprinkler module 23 in the fire extinguishing system 2, so that the sprinkler module 23 can be started to extinguish the fire as soon as the fire occurs. At the same time, it can buy enough time for the fire extinguishers to connect the fire hose and the fire hose to the fire extinguishing module 22. With the cooperation of the sprinkler module 23 and the fire extinguishing module 22, the ship 1 can be quickly extinguished, and the fire handling efficiency can be improved. The sprinkler module 23 can be set to increase the fire extinguishing area that the fire extinguishing system 2 can reach, thereby improving the overall safety performance of the ship 1. The sprinkler pipeline 231 is connected to the fire extinguishing main pipe 221, and then the sprinkler module 23 is connected to the fire extinguishing main pipe 221. The fire modules 22 can obtain the fire extinguishing medium through the same fire extinguishing main pipe 221, thereby avoiding the need to connect the sprinkler module 23 to the seawater tank 21 separately to obtain the fire extinguishing medium, and to set a sprinkler main pipe separately on the sprinkler module 23 to provide the obtained fire extinguishing medium to various areas of the sprinkler module 23, thereby reducing the use of pipes for manufacturing the fire extinguishing system 2, thereby reducing the manufacturing cost of the fire extinguishing system 2. At the same time, by connecting the sprinkler pipeline 231 to the fire extinguishing main pipe 221, the manpower consumption required for installing the sprinkler module 23 can also be reduced, thereby saving the manpower cost when installing the fire extinguishing system 2.

[0054] Furthermore, a control valve 234 is provided on the sprinkler pipe 231, and the control valve 234 is located at one end where the sprinkler pipe 231 is connected to the fire extinguishing main pipe 221. By controlling the opening and closing of the control valve 234, it is possible to control whether the fire extinguishing medium in the fire extinguishing main pipe 221 enters the sprinkler pipe 231. For example, when a fire occurs in one of the cargo hold areas 13 of the ship 1, the control valve 234 on the corresponding cargo hold area 13 can be opened, and the control valves 234 on the other cargo hold areas 13 can be closed, so that the fire extinguishing medium in the fire extinguishing main pipe 221 can enter the cargo hold area 13 where the fire occurs through the control valve 234, and extinguish the fire in the cargo hold area 13. At the same time, it also prevents the fire extinguishing medium from entering other cargo hold areas 13 where no fire occurs, thereby avoiding the waste of the fire extinguishing medium.

[0055] like Figure 5 As shown, in one embodiment of the present disclosure, the fire extinguishing system 2 may include a fire extinguishing pump 241, which is located in the stern area 12, and the fire extinguishing pump 241 is arranged in the connecting pipeline between the seawater tank 21 and the fire extinguishing module 22, and the fire extinguishing pump 241 is used to pump the fire extinguishing medium to the fire extinguishing module 22.

[0056] At this time, the fire extinguishing system 2 may include a fire main control valve 242. The seawater tank 21 is connected to the fire extinguishing module 22. The fire main control valve 242 is arranged in the connecting pipeline between the seawater tank 21 and the fire extinguishing module 22. The fire main control valve 242 is used to control the fire extinguishing medium in the seawater tank 21 to enter the fire extinguishing module 22.

[0057] like Figure 6 As shown, in another embodiment of the present disclosure, the fire extinguishing system 2 may include an emergency fire pump 251, which is located in the bow area 11, and the emergency fire pump 251 is arranged in the connecting pipeline between the fire extinguishing module 22 and the seawater tank 21, and the emergency fire pump 251 is used to pump the fire extinguishing medium to the fire extinguishing module 22.

[0058] At this time, the fire extinguishing system 2 may include an emergency master control valve 252. The seawater tank 21 is connected to the fire extinguishing module 22. The emergency master control valve 252 is arranged in the connecting pipeline between the seawater tank 21 and the fire extinguishing module 22. The emergency master control valve 252 is used to control the fire extinguishing medium in the seawater tank 21 to enter the fire extinguishing module 22.

[0059] In addition, the fire extinguishing system 2 in the embodiment of the present disclosure may include a fire extinguishing pump 241 and an emergency fire pump 251 at the same time.

[0060] Specifically, the fire extinguishing pump 241 is located in the stern area 12, and the fire extinguishing pump 241 and the fire main control valve 242 are arranged in the connecting pipeline between the seawater tank 21 and the fire extinguishing module 22, the fire main control valve 242 is used to control the fire extinguishing medium in the seawater tank 21 to enter the fire extinguishing module 22, and the fire extinguishing pump 241 is used to pump the fire extinguishing medium to the fire extinguishing module 22; the emergency fire pump 251 is located in the bow area 11, and the emergency fire pump 251 and the emergency main control valve 252 are arranged in the connecting pipeline between the fire extinguishing module 22 and the seawater tank 21, and the emergency fire pump 251 is used to pump the fire extinguishing medium to the fire extinguishing module 22.
