Description

Technical Field

[0001] The utility model relates to a fire truck, in particular to a foam and dry powder combined fire truck equipped with a mobile nitrogen supply device. Background Art

[0002] To enhance emergency rescue capabilities, combined foam and dry powder fire trucks have been introduced. However, existing combined foam and dry powder fire trucks simply combine a foam truck and a dry powder truck. Nitrogen cylinders are directly connected to the dry powder tanks, and are used together with foam and dry powder to extinguish fires. Nitrogen alone cannot be used for firefighting, making them unsuitable for special rescue situations. Further improvements are needed. Summary of the Invention

[0003] The purpose of the utility model is to provide a foam and dry powder combined fire fighting truck equipped with a mobile nitrogen supply device, which can extinguish fires by utilizing nitrogen alone and has more comprehensive rescue functions.

[0004] The technical solution of the utility model is: it includes a foam and dry powder combined fire truck body, on which a dry powder tank, a nitrogen cylinder group, a dry powder monitor and a dry powder reel are provided; the nitrogen cylinder group is connected to the dry powder tank through a pipeline and a nitrogen valve; the dry powder monitor is connected to the dry powder tank through a pipeline and a gun control valve; the dry powder reel is connected to the dry powder tank through a pipeline and a reel valve; a mobile nitrogen supply interface is connected to the pipeline between the nitrogen cylinder group and the nitrogen valve through a mobile nitrogen supply valve; and a plurality of nitrogen reel connectors are provided on the mobile nitrogen supply interface.

[0005] The technical effect of this utility model is that it has the function of mobile nitrogen supply, which increases the functionality of the fire truck and is beneficial for use in special rescue situations. By adding a mobile nitrogen supply device to the dry powder pipeline design of the fire truck, the vehicle can complete the mobile nitrogen supply task under certain special conditions, making the vehicle more versatile and applicable in a wider range of scenarios, and further facilitating the smooth progress of emergency rescue work. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 This is a schematic structural diagram of an embodiment of the present utility model. DETAILED DESCRIPTION

[0007] like Figure 1 As shown, it includes a foam and dry powder combined fire truck body 1, on which a dry powder tank 2, a nitrogen cylinder group 3, a dry powder monitor 4 and a dry powder reel 5 are provided. The nitrogen cylinder group 3 is connected to the dry powder tank 2 through a pipeline and a nitrogen valve 31. The dry powder monitor 4 is connected to the dry powder tank 2 through a pipeline and a gun control valve 41. The dry powder reel 5 is connected to the dry powder tank 2 through a pipeline and a reel valve 51. The pipeline between the nitrogen cylinder group 3 and the nitrogen valve 31 is connected to a mobile nitrogen supply interface 6 through a mobile nitrogen supply valve 61. The mobile nitrogen supply interface 6 is provided with a plurality of nitrogen reel connectors 62.

[0008] It also includes a gun purge pipeline 7, one end of which is connected to the dry powder gun 4 and the end connected to the gun control valve 41, and the other end is connected to the nitrogen valve 31 through a pipeline and the end connected to the nitrogen cylinder group 3. A gun purge valve 71 is provided on the gun purge pipeline 7.

[0009] It also includes a reel purge line 8, one end of which is connected to the end of the dry powder reel 5 connected to the reel valve 51, and the other end is connected to the end of the nitrogen valve 31 connected to the nitrogen cylinder assembly 3 through a pipeline. The reel purge line 8 is provided with a reel purge valve 81.

[0010] The gas outlet of the nitrogen cylinder group 3 is provided with a gas circuit main valve 32 and an air pressure reducing valve 33 .

[0011] The dry powder tank 2 is provided with a safety valve 21 .

[0012] The dry powder tank 2 is connected to a pressure relief pipeline 22 , and a pressure relief valve 23 is provided on the pressure relief pipeline 22 .

[0013] A pressure gauge interface 24 is provided on the pressure relief pipeline 22 between the pressure relief valve 23 and the dry powder tank 2 .

[0014] How it works:

[0015] When nitrogen is needed for mobile fire extinguishing, the nitrogen valve 31 is closed, the nitrogen reel 5 is connected to the reel valve 51, and the mobile nitrogen supply valve 61 is opened, and the nitrogen reel can be used alone for mobile fire extinguishing.

[0016] When there is no need to use nitrogen alone for mobile fire extinguishing, close the mobile nitrogen supply valve 61, open the nitrogen valve 31, and directly connect the nitrogen bottle group 3 to the dry powder tank 2 to restore the original function of extinguishing fire with dry powder nitrogen.
