[0003] When the high-rise jet fire-fighting equipment in the related technology supplies water to high-rise buildings for firefighting, when the firefighting operation is completed or suspended, there is a certain amount of water in the water hose, and the pump is prone to stop when the secondary water supply is started. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a fire-fighting fluid supply system.

[0006] A second aspect of an embodiment of the utility model provides a fire truck.

[0007] In view of this, according to the first aspect of an embodiment of the utility model, a fire-fighting fluid supply system is provided for high-rise water supply, the fire-fighting fluid supply system comprising: a liquid storage tank and an injection assembly; a pump body assembly connected to the liquid storage tank and the injection assembly; a pressure relief assembly connected to the injection assembly, the pressure relief assembly being used to discharge the liquid in the injection assembly when the pump body assembly stops working.

[0008] The fire-fighting liquid supply system provided by the embodiment of the utility model comprises a liquid storage tank, a spray assembly, a pump body assembly and a pressure relief assembly.

[0009] It is understood that a high-rise building is a high-rise building with a building height of more than 24 meters. The fire-fighting liquid supply system is used for high-rise water supply, that is, the fire-fighting liquid supply system is used for fire-fighting operations in high-rise buildings.

[0010] The pump body assembly is connected with the liquid storage tank and the injection assembly, that is, the pump body assembly can pump the liquid in the liquid storage tank to the injection assembly, and the liquid is sprayed out through the injection assembly to achieve high-rise fire fighting operations.

[0011] The pressure relief component is communicated with the injection component, and when the pump body component stops working, the pressure relief component is used to discharge the liquid in the injection component.

[0012] That is to say, when the fire-fighting fluid supply system stops or suspends fluid supply, the liquid in the injection assembly will be discharged, thereby effectively preventing the pump from shutting down when the secondary fluid supply is started, ensuring the smooth start-up of the fire-fighting fluid supply system, and extending the service life of the fire-fighting fluid supply system. Fire trucks equipped with the fire-fighting fluid supply system can extinguish fires quickly and in time, further improving fire-fighting efficiency.

[0013] In addition, the fire-fighting liquid supply system provided by the above technical solution of the utility model also has the following additional technical features:

[0014] In some technical solutions, optionally, the pressure relief assembly includes a pressure relief port and a pressure relief valve, wherein the pressure relief port is provided on the injection assembly and is connected to the injection assembly, and the pressure relief valve is provided at the pressure relief port for opening or closing the pressure relief port.

[0015] In this technical solution, it is defined that the pressure relief assembly includes a pressure relief port and a pressure relief valve. Specifically, the pressure relief port is arranged on the injection assembly, and the pressure relief port is connected to the injection assembly, so that when the fire-fighting fluid supply system stops or suspends fluid supply, the liquid in the injection assembly is discharged through the pressure relief port.

[0016] The pressure relief valve is arranged at the pressure relief port and is used to open or close the pressure relief port. Specifically, when the pump assembly is in working state, the pressure relief valve closes the pressure relief port, thereby ensuring the liquid outlet pressure of the injection assembly, increasing the injection height, meeting the liquid supply demand of high-rise buildings, and ensuring the fire extinguishing effect of the fire truck.

[0017] When the pump assembly is paused or stops working, the pressure relief valve opens the pressure relief port to discharge the liquid in the injection assembly, thereby effectively preventing the pump from shutting down when the secondary liquid supply is started, ensuring the smooth start-up of the fire protection liquid supply system.

[0018] Optionally, the spray assembly includes a nozzle and a water hose connected to each other, and the water hose is connected to the pump assembly and the nozzle. Specifically, when the pump assembly is paused or stops working, the pressure relief valve opens the pressure relief port to discharge the water in the water hose, thereby ensuring that the fire-fighting liquid supply system can be started smoothly next time, and at the same time, it is convenient for firefighters to quickly collect the water hose, reduce the difficulty of collection, and improve the working efficiency of firefighters.

Specifically, one end of the pressure relief pipeline is connected to the pressure relief tank, and the other end of the pressure relief pipeline is connected to the pressure relief port, that is, the liquid generated by the discharge of the injection assembly is recovered through the pressure relief tank, thereby reducing water stain losses compared to directly discharging the liquid generated by the discharge to the ground, and realizing centralized discharge or recycling of the recovered liquid.

[0020] Optionally, the pressure relief tank is connected to the liquid storage tank, that is, the liquid recovered from the pressure relief tank can flow into the liquid storage tank again, so that the liquid can be reused, which is beneficial to saving energy and reducing fire-fighting costs.

[0022] In this technical solution, it is defined that the pump body assembly includes at least two pump bodies. Specifically, each pump body includes a liquid inlet and a liquid outlet. The liquid inlet of each pump body is connected to the liquid storage tank respectively, and the liquid outlet of each pump body is connected to the injection assembly.

[0024] The high-lift jet fire-fighting equipment in the related technology supplies water to high-rise buildings during fire fighting. Generally, the high-lift jet fire-fighting equipment relies on the extension of the mechanical structure, and the effective fire-fighting height is limited, resulting in a relatively low spray height after adding the fire water cannon.

[0025] By setting at least two pump bodies in parallel, compared with the related technology of using the mechanical structure of the elevated fire-fighting equipment to extend the water supply to high-rise buildings, the liquid supply flow of the fire-fighting liquid supply system can be effectively increased, the liquid injection pressure can be significantly increased, and then the liquid injection height can be increased, thereby improving the fire-fighting effect of the fire truck with the fire-fighting liquid supply system.

[0026] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0027] In addition, compared with the use of drones for high-rise building rescue in related technologies, it can achieve timely and effective fire extinguishing in high-rise buildings, ensuring the safety of people’s lives and property.

The specific setting can be made according to actual needs.

[0032] Optionally, the fire-fighting liquid supply system further includes a liquid supply valve, which is disposed between the liquid storage tank and the pump assembly, and is used to control the conduction or cutoff between the liquid storage tank and the pump assembly. Specifically, the pump assembly is started, and the high-rise water supply mode is selected, that is, at least two pump bodies are turned on at the same time. The liquid supply valve is opened, and the liquid passes through at least two pump bodies and is sprayed out through the spray assembly to extinguish the fire. When the fire-fighting operation is completed, the liquid supply valve is closed, the liquid supply is stopped, the pump assembly is closed, and the pressure relief port is opened to discharge the water stored in the hose.

[0033] Optionally, the working pressure P1 of the pump assembly satisfies P1 ≥ 10 MPa. This can further increase the injection pressure of the liquid and improve the injection height of the liquid. Specifically, the injection height from one pump to the top can reach more than 300m, meeting the liquid supply demand of high-rise buildings, increasing the fire extinguishing range, and further improving the fire extinguishing effect of the fire truck with the fire liquid supply system.

[0034] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0035] In some technical solutions, optionally, the fire-fighting fluid supply system also includes a hydraulic oil pump, which is connected to at least two pump bodies and is used to drive the at least two pump bodies to work; wherein at least two pump bodies are plunger pumps.

[0036] In this technical solution, it is defined that the fire-fighting fluid supply system also includes a hydraulic oil pump. Specifically, the hydraulic oil pump is connected to at least two pump bodies, so that the hydraulic oil pump can drive at least two pump bodies to work.

[0037] At least two pump bodies are plunger pumps. Specifically, in the related art, a centrifugal pump is used to provide power for the liquid. It is understandable that the maximum working pressure of the centrifugal pump is 4 MPa.

[0038] By setting at least two pump bodies as plunger pumps, that is, driving at least two plunger pumps to work through a hydraulic oil pump, compared with the centrifugal pump in the related technology, it can output a larger liquid outlet pressure, effectively increase the injection pressure of the liquid, and thus significantly increase the injection height of the liquid, ensure the liquid supply head, meet the liquid supply needs of high-rise buildings, increase the fire extinguishing range of the fire truck with the fire liquid supply system, and improve the fire extinguishing efficiency.

[0039] Optionally, the plunger pump comprises a high pressure plunger pump.

[0040] In some technical solutions, optionally, the fire-fighting fluid supply system further includes a manifold, one end of which is connected to the fluid outlets of at least two pump bodies, and the other end of which is connected to the injection assembly.

[0041] In the technical solution, it is defined that the fire-fighting liquid supply system further includes a manifold, specifically, one end of the manifold is connected to the liquid outlets of at least two pump bodies, and the other end is connected to the injection assembly. In other words, the manifold is used to converge the liquids flowing out of at least two liquid outlets, thereby realizing the parallel arrangement of at least two pump bodies.

[0042] By setting at least two pump bodies in parallel, compared with the related technology of using the mechanical structure of the elevated fire-fighting equipment to extend the water supply to high-rise buildings, the liquid supply flow of the fire-fighting liquid supply system can be effectively increased, the liquid injection pressure can be significantly increased, and then the liquid injection height can be increased, thereby improving the fire-fighting effect of the fire truck with the fire-fighting liquid supply system.

[0043] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0046] In this technical solution, it is defined that the spray assembly includes a nozzle and a water hose. Specifically, one end of the water hose is connected to the nozzle, and the other end is connected to the pump body assembly.

[0047] Specifically, when the pump body assembly is working, the liquid in the liquid storage tank is pumped to the water hose through the pump body assembly, and after flowing through the water hose, it is sprayed out through the nozzle to extinguish the fire.

[0048] It can be understood that the water hose is laid vertically along the center seam of the stairs.

[0049] The pressure relief assembly is connected to the water hose and is used to discharge the water in the water hose when the pump assembly stops working, so as to prevent the pump from stopping due to blocking when the secondary water supply is started.

[0050] Optionally, the weight W of the water hose satisfies W≤1.5 kg / m.

[0051] Optionally, the pressure resistance value F of the water hose satisfies F ≥ 12 MPa. It is understandable that since at least two pump bodies are arranged in parallel to increase the liquid outlet pressure of the spray assembly and thus increase the spray height, the water hose is required to have a higher pressure resistance value to ensure the service life of the water hose and thus ensure the smooth progress of the firefighting operation.

[0052] Optionally, there are multiple water hoses, each of which is provided with joints at both ends, and two adjacent water hoses are detachably connected through the joints. Specifically, a joint is provided at both ends of each water hose, and two adjacent water hoses in the multiple water hoses are detachably connected through the joints, so that the water hoses can be quickly laid out during firefighting operations, and can be quickly collected after the firefighting operations are completed.

[0053] Optionally, the joint is an inner snap-on joint, which facilitates the rapid disassembly and assembly of multiple water hoses during firefighting operations.

[0057] In this technical solution, it is defined that the injection assembly also includes a liquid separator. Specifically, the liquid separator is connected to the end of the water hose facing away from the pump body assembly, that is, the liquid separator is connected to the last water hose.

[0058] The liquid distributor includes at least two liquid distributor ports, and the at least two liquid distributor ports are used to connect at least two nozzles, so that single-gun, double-gun or multi-gun fire extinguishing operations can be switched according to actual needs, thereby performing fast and reliable fire extinguishing operations according to actual needs.

[0059] Optionally, a high-pressure ball valve is provided at each liquid separation port. It can be understood that when the liquid separation port is connected to the nozzle, the high-pressure ball valve at the liquid separation port is opened. If the liquid separation port is not connected to the nozzle, the liquid separation port can be closed by the high-pressure ball valve.

[0060] In some technical solutions, optionally, the spray assembly further includes a movable reel, and each spray head is connected to a liquid dispensing port via the movable reel.

[0061] In this technical solution, it is defined that the spray assembly also includes a movable reel. Specifically, each nozzle is connected to a liquid dispensing port through the movable reel. That is to say, after the liquid enters the water hose, it first flows out through the liquid dispensing port of the liquid dispenser, then flows through the movable reel, and finally is sprayed out through the nozzle. It can be understood that the liquid dispensing port outflowing the liquid is the liquid dispensing port configured with the nozzle.

[0062] By setting up a mobile reel, it is convenient for firefighters to select a suitable fire-fighting position according to the actual fire-fighting scene, and it is convenient for firefighters to move, that is, it is convenient for firefighters to carry out fire-fighting operations and further improve fire-fighting efficiency.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0078] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0079] Refer to the following Figures 1 to 5 The fire fighting fluid supply system 100 and the fire fighting truck 300 provided according to some embodiments of the present invention are described.

[0080] In one embodiment according to the present application, Figure 1 and Figure 2 As shown, a fire-fighting fluid supply system 100 is proposed, which includes: a liquid storage tank 150 and an injection assembly 110; a pump body assembly 120, which is connected to the liquid storage tank 150 and the injection assembly 110; and a pressure relief assembly 160, which is connected to the injection assembly 110. The pressure relief assembly 160 is used to discharge the liquid in the injection assembly 110 when the pump body assembly 120 stops working.

[0081] The fire-fighting liquid supply system 100 provided in the embodiment of the utility model includes a liquid storage tank 150 , a spray assembly 110 , a pump body assembly 120 and a pressure relief assembly 160 .

[0082] It is understandable that a high-rise building is a high-rise building with a building height of more than 24 meters. The fire-fighting liquid supply system 100 is used for high-rise water supply, that is, the fire-fighting liquid supply system 100 is used for fire-fighting operations in high-rise buildings.

[0083] The pump assembly 120 is in communication with the liquid storage tank 150 and the spray assembly 110 , that is, the pump assembly 120 can pump the liquid in the liquid storage tank 150 to the spray assembly 110 , and the liquid is sprayed out through the spray assembly 110 to achieve high-rise fire fighting operations.

[0084] The pressure relief assembly 160 is in communication with the spray assembly 110 , and when the pump assembly 120 stops working, the pressure relief assembly 160 is used to discharge the liquid in the spray assembly 110 .

[0085] That is to say, when the fire-fighting fluid supply system 100 stops or suspends fluid supply, the liquid in the injection assembly 110 is discharged, thereby effectively preventing the pump from shutting down when the secondary fluid supply is started, ensuring the smooth start-up of the fire-fighting fluid supply system 100, and extending the service life of the fire-fighting fluid supply system 100, so that the fire truck 300 equipped with the fire-fighting fluid supply system 100 can quickly and timely extinguish fires, further improving fire-fighting efficiency.

[0086] In some embodiments, optionally, the pressure relief assembly 160 includes a pressure relief port and a pressure relief valve, wherein the pressure relief port is disposed on the injection assembly 110 and is connected to the injection assembly 110, and the pressure relief valve is disposed at the pressure relief port for opening or closing the pressure relief port.

[0087] In this embodiment, the pressure relief assembly 160 is defined to include a pressure relief port and a pressure relief valve. Specifically, the pressure relief port is provided on the injection assembly 110, and the pressure relief port is connected to the injection assembly 110, so that when the fire-fighting fluid supply system 100 stops or pauses the fluid supply, the liquid in the injection assembly 110 is discharged through the pressure relief port.

[0088] The pressure relief valve is arranged at the pressure relief port and is used to open or close the pressure relief port. Specifically, when the pump body assembly 120 is in working state, the pressure relief valve closes the pressure relief port, thereby ensuring the outlet pressure of the injection assembly 110, increasing the injection height, meeting the liquid supply demand of high-rise buildings, and ensuring the fire extinguishing effect of the fire truck 300.

[0089] When the pump assembly 120 is paused or stops working, the pressure relief valve opens the pressure relief port to discharge the liquid in the injection assembly 110, thereby effectively preventing the pump from stopping due to secondary liquid supply startup and ensuring the smooth startup of the fire-fighting liquid supply system 100.

[0090] Optionally, the spray assembly 110 includes a connected nozzle 111 and a water hose 112, and the water hose 112 is connected to the pump assembly 120 and the nozzle 111. Specifically, when the pump assembly 120 is paused or stops working, the pressure relief valve opens the pressure relief port to discharge the water in the water hose 112, thereby ensuring that the fire-fighting liquid supply system 100 can be started smoothly next time, and it is also convenient for firefighters to quickly collect the water hose 112, reducing the difficulty of collection and improving the working efficiency of firefighters.

[0091] Optionally, the pressure relief assembly 160 further includes a pressure relief tank and a pressure relief pipeline, wherein the two ends of the pressure relief pipeline are connected to the pressure relief tank and the pressure relief port, respectively. Specifically, one end of the pressure relief pipeline is connected to the pressure relief tank, and the other end of the pressure relief pipeline is connected to the pressure relief port, that is, the liquid generated by the discharge of the injection assembly 110 is recovered through the pressure relief tank, thereby reducing water stain losses compared to directly discharging the liquid generated by the discharge to the ground, and realizing centralized discharge or recycling of the recovered liquid.

[0092] Optionally, the pressure relief tank is connected to the liquid storage tank 150, that is, the liquid recovered by the pressure relief tank can flow into the liquid storage tank 150 again, so that the liquid can be reused, which is beneficial to saving energy and reducing fire fighting costs.

[0093] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the pump body assembly 120 includes at least two pump bodies 121, each pump body 121 includes a liquid inlet and a liquid outlet, the liquid inlet of each pump body 121 is connected to the liquid storage tank 150 respectively, and the liquid outlet of each pump body 121 is connected to the injection assembly 110.

[0094] In this embodiment, the pump body assembly 120 is defined to include at least two pump bodies 121. Specifically, each pump body 121 includes a liquid inlet and a liquid outlet. The liquid inlet of each pump body 121 is respectively connected to the liquid storage tank 150, and the liquid outlet of each pump body 121 is connected to the injection assembly 110.

[0095] That is to say, at least two pump bodies 121 are arranged in parallel. Specifically, when at least two pump bodies 121 of the pump body assembly 120 work simultaneously, the liquid in the liquid storage tank 150 enters the liquid inlet of each pump body 121 respectively, and flows out through the liquid outlet of each pump body 121. The liquid flowing out through the liquid outlets of at least two pump bodies 121 is converged and sprayed through the spray assembly 110 to extinguish the fire.

[0096] The high-lift jet fire-fighting equipment in the related technology supplies water to high-rise buildings during fire fighting. Generally, the high-lift jet fire-fighting equipment relies on the extension of the mechanical structure, and the effective fire-fighting height is limited, resulting in a relatively low spray height after adding the fire water cannon.

[0097] By setting at least two pump bodies 121 in parallel, compared with the related art of using the mechanical structure of the elevated fire-fighting equipment to extend the water supply to high-rise buildings, the liquid supply flow of the fire-fighting liquid supply system 100 can be effectively increased, the injection pressure of the liquid can be significantly increased, and then the injection height of the liquid can be increased, thereby improving the fire-fighting effect of the fire truck 300 with the fire-fighting liquid supply system 100.

[0098] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0099] In addition, compared with the use of drones for high-rise building rescue in related technologies, it can achieve timely and effective fire extinguishing in high-rise buildings, ensuring the safety of people’s lives and property.

[0100] Optionally, the fire-fighting fluid supply system 100 includes multiple working modes to broaden the fire-fighting scenarios of the fire-fighting fluid supply system 100 .

[0101] Specifically, the multiple working modes include a first working mode and a second working mode, wherein in the first working mode, at least two pump bodies 121 start working simultaneously and converge at at least two liquid outlets, ie, a high-level water supply mode.

[0102] In the second working mode, any one of the at least two pump bodies 121 starts working, that is, the low zone water supply mode.

[0103] Optionally, the multiple working modes may further include a third working mode, in which at least two pump bodies 121 do not converge at the liquid outlet, but are respectively connected to the nozzles 111, so that when extinguishing a fire on the ground, the fire extinguishing efficiency is increased by increasing the number of nozzles 111. The specific setting can be made according to actual needs.

[0104] Alternatively, if Figure 5 As shown, the fire fighting liquid supply system 100 also includes a liquid supply valve (water supply valve), which is arranged between the liquid storage tank 150 and the pump body assembly 120, and is used to control the conduction or cutoff between the liquid storage tank 150 and the pump body assembly 120. Specifically, the pump body assembly 120 (fire fighting pump) is started, and the high-level water supply mode is selected, that is, at least two pump bodies 121 are turned on at the same time. The liquid supply valve is opened, and the liquid passes through at least two pump bodies 121 and is sprayed out through the spray assembly 110 to extinguish the fire. When the fire fighting operation is completed, the liquid supply valve is closed, the liquid supply is stopped, the pump body assembly 120 is closed, and the pressure relief port is opened through the pressure relief valve to discharge the water stored in the water hose 112.

[0105] Optionally, the working pressure P1 of the pump assembly 120 satisfies P1 ≥ 10 MPa. This can further increase the injection pressure of the liquid and improve the injection height of the liquid. Specifically, the injection height from one pump to the top can reach more than 300 m, meeting the liquid supply demand of high-rise buildings, increasing the fire extinguishing range, and further improving the fire extinguishing effect of the fire truck 300 with the fire-fighting liquid supply system 100.

[0106] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0107] In some embodiments, optionally, the fire-fighting fluid supply system 100 further includes a hydraulic oil pump, which is connected to at least two pump bodies 121 and is used to drive at least two pump bodies 121 to work; wherein at least two pump bodies 121 are plunger pumps.

[0108] In this embodiment, it is defined that the fire-fighting fluid supply system 100 further includes a hydraulic oil pump. Specifically, the hydraulic oil pump is in communication with at least two pump bodies 121 , so that the hydraulic oil pump can drive at least two pump bodies 121 to work.

[0109] At least two pump bodies 121 are plunger pumps. Specifically, in the related art, a centrifugal pump is used to provide power for the liquid. It is understandable that the maximum working pressure of the centrifugal pump is 4 MPa.

[0110] By setting at least two pump bodies 121 as plunger pumps, that is, driving at least two plunger pumps to work through a hydraulic oil pump, compared with the centrifugal pump in the related technology, a larger liquid outlet pressure can be output, effectively increasing the injection pressure of the liquid, and then significantly increasing the injection height of the liquid, ensuring the liquid supply head, meeting the liquid supply needs of high-rise buildings, increasing the fire extinguishing range of the fire truck 300 with the fire-fighting liquid supply system 100, and improving the fire extinguishing efficiency.

[0111] Optionally, the plunger pump comprises a high pressure plunger pump.

[0112] In some embodiments, optionally, the fire-fighting fluid supply system 100 further includes a manifold, one end of which is connected to the fluid outlets of at least two pump bodies 121 , and the other end of which is connected to the injection assembly 110 .

[0113] In this embodiment, the fire-fighting liquid supply system 100 is defined to further include a manifold, specifically, one end of the manifold is connected to the liquid outlets of at least two pump bodies 121, and the other end is connected to the injection assembly 110. In other words, the manifold is used to converge the liquids flowing out of at least two liquid outlets, thereby realizing the parallel arrangement of at least two pump bodies 121.

[0114] By setting at least two pump bodies 121 in parallel, compared with the related art of using the mechanical structure of the elevated fire-fighting equipment to extend the water supply to high-rise buildings, the liquid supply flow of the fire-fighting liquid supply system 100 can be effectively increased, the injection pressure of the liquid can be significantly increased, and then the injection height of the liquid can be increased, thereby improving the fire-fighting effect of the fire truck 300 with the fire-fighting liquid supply system 100.

[0115] Moreover, a higher spraying height can be achieved without installing additional booster pumps on the refuge floors or middle floors of high-rise buildings, which can effectively reduce the assembly steps of fire-fighting equipment and significantly improve fire-fighting efficiency.

[0116] Optionally, the fire-fighting fluid supply system 100 further includes a fluid supply interface, which is communicated with the manifold, and the injection assembly 110 is detachably connected to the fluid supply interface, thereby realizing the installation and removal of the injection assembly 110 .

[0117] like Figure 2 and Figure 4 As shown, in some embodiments, optionally, the spray assembly 110 includes a spray head 111 and a water hose 112 , wherein the water hose 112 is respectively connected to the spray head 111 and the pump body assembly 120 , and the pressure relief assembly 160 is connected to the water hose 112 .

[0118] In this embodiment, the spray assembly 110 is defined to include a spray head 111 and a water hose 112 . Specifically, one end of the water hose 112 is connected to the spray head 111 , and the other end is connected to the pump body assembly 120 .

[0119] Specifically, when the pump body assembly 120 is working, the liquid in the liquid storage tank 150 is pumped to the water hose 112 through the pump body assembly 120, and after flowing through the water hose 112, it is sprayed out through the nozzle 111 to extinguish the fire.

[0120] It can be understood that the water hose 112 is laid vertically along the center seam of the stairs.

[0121] The pressure relief assembly 160 is connected to the water hose 112 and is used to discharge the water in the water hose 112 when the pump assembly 120 stops working, so as to prevent the pump from stopping due to blocking when the secondary water supply is started.

[0122] Optionally, the weight W of the water hose 112 satisfies W≤1.5 kg / m. That is, the weight of the water hose 112 is set to be relatively small, so that it is convenient for firefighters to lay the water hose 112, reduce the difficulty of firefighting operations, and further improve firefighting efficiency.

[0123] Optionally, the pressure resistance value F of the water hose 112 satisfies F≥12MPa. It is understandable that, since at least two pump bodies 121 are arranged in parallel to increase the liquid outlet pressure of the spray assembly 110 and thus increase the spray height, the water hose 112 is required to have a higher pressure resistance value to ensure the service life of the water hose 112 and thus ensure the smooth progress of the firefighting operation.

[0124] Optionally, there are multiple water hoses 112, and joints are provided at both ends of each water hose 112, and two adjacent water hoses 112 are detachably connected through the joints. Specifically, a joint is provided at both ends of each water hose 112, and two adjacent water hoses 112 in the multiple water hoses 112 are detachably connected through the joints, so that the water hoses 112 can be quickly laid out during firefighting operations, and can be quickly collected after the firefighting operations are completed.

[0125] Optionally, the joint is an inner snap-on joint, which facilitates the quick disassembly and assembly of multiple water hoses 112 during firefighting operations.

[0126] Optionally, each joint includes a locking structure, so that after two adjacent water hoses 112 are connected via the joint, the locking structure can prevent disengagement, thereby ensuring that the laying process of the water hose 112 can be safe, reliable and quick.

[0127] Optionally, multiple water hoses 112 are connected in sequence, wherein the joint of the water hose 112 close to the pump body assembly 120 is connected to the liquid supply interface, that is, the first water hose 112 is connected to the liquid supply interface, and the last water hose 112 is connected to the nozzle 111.

[0128] like Figure 2 and Figure 4 As shown, in some embodiments, optionally, the injection assembly 110 also includes a liquid separator 130, which is connected to the end of the water hose 112 away from the pump body assembly 120, and the liquid separator 130 includes at least two liquid separation ports 131, and the at least two liquid separation ports 131 are used to connect at least two nozzles 111.

[0129] In this embodiment, it is defined that the spray assembly 110 further includes a liquid separator 130 . Specifically, the liquid separator 130 is connected to the end of the water hose 112 away from the pump body assembly 120 , that is, the liquid separator 130 is connected to the last water hose 112 .

[0130] The liquid distributor 130 includes at least two liquid distributor ports 131, and the at least two liquid distributor ports 131 are used to connect at least two nozzles 111, so that single-gun, double-gun or multi-gun fire extinguishing operations can be switched according to actual needs, thereby performing fast and reliable fire extinguishing operations according to actual needs.

[0131] Optionally, a high-pressure ball valve is provided at each liquid separation port 131. It can be understood that when the liquid separation port 131 is connected to the nozzle 111, the high-pressure ball valve at the liquid separation port 131 is opened. If the liquid separation port 131 is not connected to the nozzle 111, the liquid separation port 131 can be closed by the high-pressure ball valve.

[0132] like Figure 2 and Figure 4 As shown, in some embodiments, optionally, the spray assembly 110 further includes a movable reel 140 , and each spray head 111 is connected to a liquid dispensing port 131 via the movable reel 140 .

[0133] In this embodiment, it is defined that the spray assembly 110 further includes a movable reel 140. Specifically, each spray head 111 is connected to a liquid separation port 131 through the movable reel 140. That is, after the liquid enters the water hose 112, it first flows out through the liquid separation port 131 of the liquid separator 130, then flows through the movable reel 140, and finally is sprayed out through the spray head 111. It can be understood that the liquid separation port 131 from which the liquid flows out is the liquid separation port 131 of the spray head 111.

[0134] By providing the mobile reel 140 , it is convenient for firefighters to select a suitable fire-fighting position according to the actual fire-fighting scene, and it is convenient for firefighters to move, that is, it is convenient for firefighters to carry out fire-fighting operations, and the fire-fighting efficiency is further improved.

[0135] In some embodiments, optionally, the fire-fighting fluid supply system 100 further includes a fixing component, which is disposed on the water hose 112 and is used to fix the water hose 112 .

[0136] In this embodiment, it is defined that the fire-fighting fluid supply system 100 also includes a fixing part. Specifically, the fixing part is arranged on the water hose 112, and the fixing part is used to fix the water hose 112, thereby improving the stability and reliability of the water hose 112 during the fire-fighting process, and further improving the fire-fighting efficiency of the fire truck 300 having the fire-fighting fluid supply system 100.

[0137] It can be understood that the water hose 112 is laid vertically along the center seam of the stairs, and the water hose 112 can be directly fixed to the stair railing through a fixing piece to improve the installation stability of the water hose 112 during the fire extinguishing process.

[0138] Optionally, the fixing member includes but is not limited to a strap.
