[0025] Please refer to Figs. 1-2 It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached to the specification are only used to understand and read the content disclosed in the specification for those skilled in the art, and are not used to limit the conditions that can be implemented by the utility model, so they do not have technical significance.

[0026] Please refer to Fig. 1 and Fig. 2The embodiment provides a fire-fighting module, which comprises a storage unit 1, a release pipeline 3 and a pneumatic pipeline 4. The storage unit 1 stores compressed gas and fire extinguishing agent, and is provided with a pneumatic on-off valve 2; the fire extinguishing agent is used for fire extinguishing, and the compressed gas is used for driving the fire extinguishing agent to be discharged. In the embodiment, the fire extinguishing agent is dry powder fire extinguishing agent, and in other alternative specific embodiments, the fire extinguishing agent can also be foam fire extinguishing agent or other fire extinguishing agent. It can be understood that the compressed gas should be selected from gases that are non-combustible, difficult to burn, chemically stable and helpful to fire extinguishing, such as nitrogen and carbon dioxide.
[0027] The release pipeline 3 is used for releasing the fire extinguishing agent, the pneumatic on-off valve 2 on the storage unit 1 is provided with a fire extinguishing agent discharge port in communication with the release pipeline 3, and the fire extinguishing agent discharge port discharges the compressed gas and the fire extinguishing agent in the storage unit 1 to the release pipeline 3.
[0028] In the embodiment, the storage unit 1 is at least two, and at least one storage unit 1 is an emergency unit; the fire extinguishing agent discharge port of the pneumatic on-off valve 2 on the emergency unit is also in communication with the pneumatic pipeline 4; the pneumatic pipeline 4 is used for driving the pneumatic on-off valve 2 to be opened; the pneumatic on-off valve 2 is provided with a gas source interface in communication with the pneumatic pipeline 4, so as to receive the driving gas of the pneumatic pipeline 4; and the pneumatic pipeline 4 is in communication with at least the gas source interface of the pneumatic on-off valve 2 on another storage unit 1.
[0029] Since the storage unit 1 stores the compressed gas, when the gas source 5 cannot normally work, the pneumatic on-off valve 2 on the emergency unit is manually opened, the compressed gas in the emergency unit can enter the pneumatic pipeline 4, and then enter the gas source interface of the pneumatic on-off valve 2 on another storage unit 1 through the pneumatic pipeline 4, so as to drive the other storage unit 1 to be opened. It is not necessary to manually open each storage unit 1 one by one, which is helpful to meet the fire extinguishing time limit and ensure the fire extinguishing effect. In the embodiment, the storage unit 1 is a fire extinguishing agent cylinder, but it can be understood that the storage unit 1 can also be a fire extinguishing agent tank, a fire extinguishing agent barrel or other pressure-resistant containers capable of storing compressed gas and fire extinguishing agent.
[0030] In the embodiment, the storage unit 1 in the fire-fighting module is multiple, and the pneumatic pipeline 4 is connected with the gas source interface of the pneumatic on-off valve 2 on each storage unit 1. When the gas source cannot normally work, the pneumatic on-off valve 2 on the emergency unit is manually opened, so as to open each storage unit 1 in the fire-fighting module, accelerate the response speed of the fire-fighting module and reduce the workload of the operator.
[0031] In the embodiment, the gas source interface is communicated with the inlet of the variable-diameter tee joint 16, the release pipeline 3 is communicated with the first outlet of the variable-diameter tee joint 16, the second outlet of the variable-diameter tee joint 16 is communicated with the pneumatic pipeline 4, and the inner diameter of the first outlet is smaller than that of the second outlet, so that most of the compressed gas in the emergency unit can enter the pneumatic pipeline 4, and the pneumatic pipeline 4 can obtain sufficient compressed gas to open other storage units 1.
[0032] In the embodiment, the second outlet is communicated with the pneumatic pipeline 4 through the first communication pipeline 6, and the one-way valve 8 is arranged on the first communication pipeline 6 and passes through the second outlet to the pneumatic pipeline 4. The one-way valve 8 on the first communication pipeline 6 can avoid the leakage of the starting gas source 5 into the release pipeline 3 along the first communication pipeline 6 in the normal working condition, so that the compressed gas in the starting gas source 5 can reach the pneumatic on-off valve 2 of each storage unit 1 through the pneumatic pipeline 4 in the normal working condition, and each storage unit 1 can be normally opened.
[0033] In the embodiment, the low-leakage high-sealing valve 9 is arranged on the pneumatic pipeline 4, and the safety pressure relief valve 10 is arranged on the release pipeline 3. Due to the machining process and other reasons, sometimes part of the gas in the starting gas source 5 leaks into the pneumatic pipeline 4. The low-leakage high-sealing valve 9 can discharge the gas with low pressure when the gas pressure in the pneumatic pipeline 4 is low, so as to avoid the gas accumulation in the pneumatic pipeline 4 and trigger the pneumatic on-off valve 2 on the storage unit 1 by mistake. When the number of opened storage units 1 is too large or the release pipeline 3 is blocked, the gas pressure in the release pipeline 3 is too high and exceeds the opening threshold of the safety pressure relief valve 10, the safety pressure relief valve 10 is opened to release the pressure of the release pipeline 3, so as to avoid the damage or explosion of the release pipeline 3 due to the too high pressure.
[0034] In the embodiment, the fire-fighting module further comprises a starting gas source 5, the starting gas source 5 is provided with a starting valve, and the pneumatic pipeline 4 is connected with the starting gas source 5 through the starting valve. In the embodiment, the starting gas source 5 is a starting gas cylinder, and the inside of the starting gas cylinder stores compressed gas. It can be understood that the storage unit 1 can also be a starting gas tank, a starting gas barrel or other pressure-resistant containers capable of storing compressed gas
[0035] In the embodiment, a plurality of nozzles 7 are arranged on the release pipeline 3 in sequence, and each nozzle 7 is arranged along the extension direction of the release pipeline 3. The nozzles 7 are used for releasing compressed gas and fire extinguishing agent to the fire area, so as to achieve fire extinguishing.
[0036] Please refer to Fig. 2 The embodiment also provides a fire-fighting system, which comprises at least two fire-fighting modules as any one of the above, and the release pipelines 3 of the two fire-fighting modules are communicated with each other, and the two fire-fighting modules can share the storage unit 1.
[0037] In the embodiment, the two fire-fighting modules of the fire-fighting system are a main fire-fighting module 15 and a secondary fire-fighting module 14, the number of the storage units 1 in the main fire-fighting module 15 is greater than the number of the storage units 1 in the secondary fire-fighting module 14, the pneumatic pipeline 4 of the main fire-fighting module 15 is communicated with the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the second communication pipeline 12, the one-way valve 8 is arranged on the second communication pipeline 12, and the gas in the pneumatic pipeline 4 of the main fire-fighting module 15 enters the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the one-way valve 8.
[0038] Since the number of the storage units 1 in the secondary fire-fighting module 14 is small, when the fire situation is only in the fire-fighting area corresponding to the secondary fire-fighting module 14, the secondary fire-fighting module 14 can be started to extinguish the fire, when the starting gas source 5 of the secondary fire-fighting module 14 is started, the gas in the starting gas source 5 of the secondary fire-fighting module 14 cannot enter the pneumatic pipeline 4 of the main fire-fighting module 15 through the second communication pipeline 12, and the storage units 1 in the main fire-fighting module 15 are prevented from being started. Since the number of the storage units 1 in the main fire-fighting module 15 is large, when the fire situation is serious or the fire area is not limited to the fire-fighting area corresponding to the secondary fire-fighting module 14, the main fire-fighting module 15 can be started to extinguish the fire, and the gas in the starting gas source 5 of the main fire-fighting module 15 can enter the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the second communication pipeline 12, so that the storage units 1 of the secondary fire-fighting module 14 are started to extinguish the fire, and the timeliness and the extinguishing effect of the fire extinguishing are ensured.
[0039] In the embodiment, the two fire-fighting modules of the fire-fighting system are a main fire-fighting module 15 and a secondary fire-fighting module 14, the number of the storage units 1 in the main fire-fighting module 15 is greater than the number of the storage units 1 in the secondary fire-fighting module 14, the pneumatic pipeline 4 of the main fire-fighting module 15 is communicated with the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the second communication pipeline 12, the one-way valve 8 is arranged on the second communication pipeline 12, and the gas in the pneumatic pipeline 4 of the main fire-fighting module 15 enters the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the one-way valve 8.
[0040] Since the number of the storage units 1 in the secondary fire-fighting module 14 is small, when the fire situation is only in the fire-fighting area corresponding to the secondary fire-fighting module 14, the secondary fire-fighting module 14 can be started to extinguish the fire, when the starting gas source 5 of the secondary fire-fighting module 14 is started, the gas in the starting gas source 5 of the secondary fire-fighting module 14 cannot enter the pneumatic pipeline 4 of the main fire-fighting module 15 through the second communication pipeline 12, and the storage units 1 in the main fire-fighting module 15 are prevented from being started. Since the number of the storage units 1 in the main fire-fighting module 15 is large, when the fire situation is serious or the fire area is not limited to the fire-fighting area corresponding to the secondary fire-fighting module 14, the main fire-fighting module 15 can be started to extinguish the fire, and the gas in the starting gas source 5 of the main fire-fighting module 15 can enter the pneumatic pipeline 4 of the secondary fire-fighting module 14 through the second communication pipeline 12, so that the storage units 1 of the secondary fire-fighting module 14 are started to extinguish the fire, and the timeliness and the extinguishing effect of the fire extinguishing are ensured.
[0041] In the present example, a selector valve 11 is arranged on the release line 3 of each fire-fighting module between the storage unit 1 and the nozzle 7, and the selector valve 11 can close the release line 3 of the corresponding fire-fighting module, thereby selecting the discharge area of the fire extinguishing agent in the fire-fighting system.
[0042] In summary, the fire-fighting module and the fire-fighting system of the present embodiment have at least one emergency unit, the discharge port of the pneumatic selector valve 2 of the emergency unit is also connected to the pneumatic line 4, the pneumatic line 4 is connected to the gas source interface of the pneumatic selector valve 2 of another storage unit 1, and compressed gas is stored in the storage unit 1. When the gas source fails to work normally, the pneumatic selector valve 2 of the emergency unit is manually opened, and the compressed gas in the emergency unit enters the pneumatic line 4, and then enters the gas source interface of the pneumatic selector valve 2 of another storage unit 1 through the pneumatic line 4, thereby driving another storage unit 1 to open. It is not necessary to manually open each storage unit 1 one by one, which is conducive to meeting the fire-fighting time limit and ensuring the fire-fighting effect.
