[0050] The following combination Figures 1-6 The specific structure and working principle of the multi-gun coordinated fire extinguishing system of the present invention are described.

[0051] like Figure 1 As shown, the multi-gun coordinated fire extinguishing system includes a fire pump 10, a main gun pipeline device 20, a secondary gun pipeline device 30, and a vehicle-mounted gun pipeline device 40. The main gun pipeline device 20 is connected to the fire pump 10, and the secondary gun pipeline device 30 is connected to the main gun pipeline device 20. The vehicle-mounted gun pipeline device 40 is connected to the main gun pipeline device 20 and is used to extinguish open fires on the ground.

[0052] The control device is electrically connected to the fire pump 10, the main gun pipeline device 20, the secondary gun pipeline device 30 and the front gun pipeline device 40. The control device is used to control the opening or closing of the main gun pipeline device 20, the secondary gun pipeline device 30 and the front gun pipeline device 40, and to adjust the power of the fire pump 10.

[0053] The multi-gun coordinated fire extinguishing system provided by the present invention has a control device that adjusts the power of the fire pump 10 according to whether the main gun pipeline device 20, the secondary gun pipeline device 30 and the front gun pipeline device 40 are working. This can meet the simultaneous operation of multiple pipeline devices, realize simultaneous fire extinguishing and cooling, and achieve three-dimensional fire extinguishing in different directions and angles, thereby improving the efficiency of fire extinguishing and rescue.

[0054] It should be noted here that the maximum power of the fire pump 10 needs to be greater than or equal to the water demand when the main gun pipeline device 20, the secondary gun pipeline device 30, the front gun pipeline device 40 and the sprinkler pipeline device 60 are opened at the same time.

[0055] In one embodiment of the present invention, Figure 2 As shown, the main gun pipeline device 20 includes a fire main gun 21 and a main gun pipeline 22. The fire main gun 21 is mainly used to extinguish open flames and has a high flow rate and pressure. The fire main gun 21 is installed on the top of the fire truck body 70. Preferably, the fire main gun 21 is installed at a position near the top front of the fire truck body 70.

[0056] The input end of the main gun pipeline 22 is connected to the output end of the fire pump 10, and the output end of the main gun pipeline 22 is connected to the main fire gun 21. The auxiliary gun pipeline device 30 and the front gun pipeline device 40 are both connected to the main gun pipeline 22. The water pumped by the fire pump 10 can be used to extinguish fires not only in the main fire gun 21, but also in the auxiliary gun pipeline device 30 and the front gun pipeline device 40.

[0057] In one embodiment of the present invention, Figure 2As shown, the main gun pipeline device 20 also includes a main gun pressure regulating valve 23 and a main gun pressure sensor 24. The main gun pressure regulating valve 23 is arranged on the main gun pipeline 22. The main gun pressure regulating valve 23 is electrically connected to the control device. The main gun pressure regulating valve 23 is used to adjust the water pressure output by the main gun pipeline 22. The main gun pressure regulating valve 23 can control the inlet water pressure of the fire main gun 21 by adjusting the water pressure output by the main gun pipeline 22.

[0058] The main gun pressure sensor 24 is installed in the main gun pipeline 22 between the main gun pressure regulating valve 23 and the main fire gun 21. The main gun pressure sensor 24 is electrically connected to the control device and is used to detect the pressure at the inlet of the main fire gun 21. The control device controls the opening of the main gun pressure regulating valve 23 based on received parameters to control the water pressure output from the main gun pipeline 22. The main gun pressure sensor 24 detects the pressure at the inlet of the main fire gun 21 and transmits the pressure value to the control device. Based on the pressure value, the control device determines whether the opening of the main gun pressure regulating valve 23 needs to be readjusted.

[0059] A pressure detection port is provided on the main gun pipeline 22, and an internal thread is provided on the inner wall of the pressure detection port. The main gun pressure sensor 24 is provided in the pressure detection port and cooperates with the inner wall thread of the pressure detection port.

[0060] In one embodiment of the present invention, Figure 2 As shown, the main gun pipeline device 20 also includes a multi-way connector 25, which is used to connect the outgoing water pipeline 50 with the main gun pipeline 22. The multi-way connector 25 is connected in series to the main gun pipeline 22 between the main gun pressure regulating valve 23 and the fire pump 10. The interface of the multi-way connector 25 can be welded or flanged to the main gun pipeline 22. By providing the multi-way connector 25 on the main gun pipeline 22, the outgoing water pipeline 50 and the main gun pipeline 22 can be connected conveniently, improving assembly efficiency.

[0061] In one embodiment of the present invention, Figure 3 As shown, the fire extinguishing system further includes an outgoing water pipe 50 , which is used to output water to the outside. The outgoing water pipe 50 is connected to the corresponding interface of the multi-way connector 25 .

[0062] The secondary gun pipeline assembly 30 and the front gun pipeline assembly 40 are both connected to an outgoing water pipeline 50. At least one control valve 51 is provided at the end of the outgoing water pipeline 50 away from the multi-way connector 25. This control valve 51 is normally closed. When water needs to be discharged to the outside, the control valve 51 can be opened manually or via a control device. In this embodiment, each outgoing water pipeline 50 is provided with two control valves 51 at the end away from the multi-way connector 25, spaced apart. Of course, the number of control valves 51 is not limited to this; a larger number of control valves 51 may also be provided.

[0063] In one embodiment of the present invention, Figure 3 As shown, the fire extinguishing system includes two external water pipes 50, which are symmetrically arranged on either side of the fire pump 10. The multi-way connector 25 is a four-way connector, and the interfaces on both sides of the four-way connector are respectively connected to the two external water pipes 50. Preferably, the interfaces on both sides of the four-way connector are provided with flanges, and the input ends of the two external water pipes 50 are both provided with flanges, and the interfaces on both sides of the four-way connector are respectively connected to the two external water pipes 50 through the flanges.

[0064] One of the two outgoing water pipes 50 is connected to the auxiliary gun pipe device 30, and the other of the two outgoing water pipes 50 is connected to the front gun pipe device 40. Specifically, Figure 1 and Figure 4 As shown, the outgoing water pipeline 50 on the left is connected to the auxiliary gun pipeline device 30, and the outgoing water pipeline 50 on the right is connected to the front gun pipeline device 40.

[0065] In one embodiment of the present invention, Figure 2 As shown, the main gun pipeline 22 between the multi-way connector 25 and the fire pump 10 is provided with a pump outlet pressure sensor 11, which is electrically connected to the control device. The pump outlet pressure sensor 11 is used to detect the pressure value at the outlet of the fire pump 10 and in the external water pipeline 50.

[0066] In one embodiment of the present invention, Figure 4 As shown, the secondary gun pipeline assembly 30 includes a secondary gun 31, a secondary gun pipeline 32, a secondary gun pressure regulating valve 33, and a secondary gun pressure sensor 34. The secondary gun 31 is primarily used to rapidly cool combustible materials to prevent secondary re-ignition or deflagration. The input end of the secondary gun pipeline 32 is connected to the left-side external water supply pipeline 50. The output end of the secondary gun pipeline 32 is connected to two secondary guns 31, that is, two secondary guns 31 are disposed at the ends of the secondary gun pipeline 32. Preferably, the secondary guns 31 are connected to the ends of the secondary gun pipeline 32 via flanges. The two secondary guns 31 are located on either side of the rear of the main gun 21. Of course, the number of secondary guns 31 is not limited to this number and is determined based on actual needs. The two secondary guns 31 can be of the same or different models.

[0067] The secondary gun pressure regulating valve 33 is installed in the secondary gun pipeline 32. It is used to adjust the water pressure output by the secondary gun pipeline 32. Specifically, the secondary gun pressure regulating valve 33 is located at the end of the secondary gun pipeline 32 near the outgoing water pipe 50. The secondary gun pressure sensor 34 is installed in the secondary gun pipeline 32 between the secondary gun pressure regulating valve 33 and the fire fighting secondary gun 31. The installation of the secondary gun pressure sensor 34 in the secondary gun pipeline 32 between the secondary gun pressure regulating valve 33 and the fire fighting secondary gun 31 can more accurately detect the water pressure adjusted by the secondary gun pressure regulating valve 33.

[0068] The secondary gun pressure sensor 34 is electrically connected to the control device and is used to detect the pressure at the inlet of the secondary fire gun 31. The secondary gun pressure sensor 34 monitors the pressure at the inlet of the secondary fire gun 31 in real time and transmits the pressure value to the control device. The control device then controls the opening of the secondary gun pressure regulating valve 33 based on the detected pressure value to control the water pressure output from the secondary gun pipeline 32, ensuring that the water pressure output from the secondary fire gun 31 meets the required operating pressure.

[0069] In one embodiment of the present invention, Figure 5 As shown, the front gun pipeline device 40 includes a front fire monitor 41, a front gun pipeline 42, a front gun pressure regulating valve 43, and a front gun pressure sensor 44. The front fire monitor 41 is used to handle ground-level flowing fires, ensuring the safety of firefighters and vehicles. The input end of the front gun pipeline 42 is connected to the other of the two outgoing water pipelines 50, and the output end of the front gun pipeline 42 is connected to the front fire monitor 41. Specifically, the rear end of the front gun pipeline 42 is connected to the left outgoing water pipeline 50, and the front end of the front gun pipeline 42 is connected to the front fire monitor 41. Because the front fire monitor 41 and the fire auxiliary gun 31 both have large water outputs, connecting the front fire monitor 41 and the fire auxiliary gun 31 to different outgoing water pipelines 50 can prevent the front fire monitor 41 and the fire auxiliary gun 31 from affecting each other when they discharge water simultaneously.

[0070] A front gun pressure regulating valve 43 is installed in the front gun pipeline 42 and is electrically connected to the control device. It regulates the water pressure output from the front gun pipeline 42. A front gun pressure sensor 44 is installed in the front gun pipeline 42 between the front gun pressure regulating valve 43 and the front fire monitor 41. The pressure sensor 44 is electrically connected to the control device and is used to detect the pressure at the inlet of the front fire monitor 41. Specifically, the pressure sensor 44 is installed at the front end of the front gun pipeline 42. The fire truck body 70 is relatively long, with the outgoing water pipeline 50 located at the rear of the fire truck body 70 and the front fire monitor 41 installed at the front of the fire truck body 70. As a result, the front gun pipeline 42 is relatively long, and the pressure difference between the front and rear ends of the front gun pipeline 42 is relatively large. If the front gun pressure sensor 44 is set at the rear end of the front gun pipeline 42, the pressure value detected by the front gun pressure sensor 44 will be greatly different from the pressure value at the inlet of the front fire cannon 41. Therefore, the front gun pressure sensor 44 is set in the front gun pipeline 42 between the front gun pressure regulating valve 43 and the front fire cannon 41, that is, the front gun pressure sensor 44 is set at the front end of the front gun pipeline 42. The front gun pressure sensor 44 can accurately detect the pressure value at the inlet of the front fire cannon 41.

[0071] When the fire extinguishing system is turned on, you only need to select the fire-fighting pipeline device that needs to be turned on. The control device automatically controls the power of the fire pump 10 and controls the pressure regulating valve to adjust the pressure in the pipeline to ensure that the fire extinguishing system can respond to fire incidents in a timely manner and provide effective fire extinguishing measures.

[0072] The pressure sensor can monitor the working water pressure in the corresponding fire-fighting pipeline device in real time. When the number of fire-fighting pipeline devices in the fire-fighting system changes suddenly, the control device can quickly adjust the fire-fighting system according to the pressure value detected by the pressure sensor to ensure that all fire-fighting pipeline devices are working under rated working conditions, achieving the best three-dimensional fire-fighting effect, thereby increasing the success rate of fire-fighting.

[0073] In one embodiment of the present invention, Figure 6 As shown, the fire extinguishing system also includes a sprinkler pipe system 60, which is used to cool the fire truck. The sprinkler pipe system 60 includes a main sprinkler line 61, multiple sprinkler nozzles 62, a spray pressure sensor 63, and a sprinkler line pressure regulating valve 64. The main sprinkler line 61 is installed on the periphery of the fire truck body 70. The input end of the main sprinkler line 61 is connected to the outgoing water pipe 50 on the left side.

[0074] Multiple spray nozzles 62 are spaced apart in the main spray line 61. The distance between two adjacent spray nozzles 62 can be the same or different. A spray line pressure regulating valve 64 is provided at the input end of the main spray line 61. A spray pressure sensor 63 is provided in the main spray line 61 between the spray line pressure regulating valve 64 and the spray nozzles 62. The spray pressure sensor 63 and the spray line pressure regulating valve 64 are both electrically connected to the control device. The spray line pressure regulating valve 64 is used to adjust the pressure value in the main spray line 61, and the spray pressure sensor 63 is used to detect the pressure value in the main spray line 61.

[0075] Since each pipeline device is equipped with a pressure sensor, the internal pressure of each pipeline is monitored in real time through the pressure sensor. The pressure sensor sends the data to the control device, and the control device determines whether the pressure of each pipeline is the rated pressure; if the pressure is the rated pressure, the opening of the pressure regulating valve of each pipeline device remains unchanged; if the pressure inside the pipeline device is not the rated pressure, the pressure regulating valve in the pipeline device is adjusted until the pressure inside the pipeline device is equal to the rated pressure.

[0076] The fire truck body 70 is equipped with an infrared sensor, which is electrically connected to a control unit. During firefighting operations, the control unit automatically activates various piping systems based on temperature changes at the scene. When the infrared sensor detects a rapid rise in the temperature of combustibles at the fire scene, the control unit automatically activates the auxiliary gun piping system 30. When the infrared sensor detects a flowing fire on the ground, the control unit automatically activates the front fire monitor 41. When the infrared sensor detects an excessively high temperature within the fire truck itself, the control unit automatically activates the sprinkler piping system 60.

[0077] When facing large petrochemical fires, the main firefighting cannon 21 is primarily used to extinguish open flames, using high-pressure water jets or dry powder fire extinguishing agents to extinguish flames. The secondary firefighting cannon 31 is used to rapidly cool combustible materials, spraying large amounts of water mist to rapidly lower the temperature around the fire source and reduce the risk of fire spread. The front firefighting cannon 41 is used to handle surface fires, using high-pressure water jets or water mist to quickly extinguish surface fires and prevent them from spreading. The sprinkler system 60 also reduces the temperature around the fire truck.

[0078] The working process of the fire extinguishing system: When all the pressure regulating valves in the multi-gun coordinated fire extinguishing system are opened, water enters the fire pump 10 from the pump suction pipe or the external suction pipe. The water pressurized by the fire pump 10 passes through the pump outlet pressure sensor 11 and enters the main gun pipeline 22 and the outgoing water pipelines 50 on both sides; the water entering the main gun pipeline 22 passes through the main gun pressure regulating valve 23 and the main gun pressure sensor 24 and enters the fire main gun 21; the water entering the left outgoing water pipeline 50 enters the sprinkler main pipeline 61 and the auxiliary gun pipeline 32 respectively through the sprinkler pipeline pressure regulating valve 64 and the auxiliary gun pressure regulating valve 33; the water entering the right outgoing water pipeline 50 enters the front gun pipeline 42 after pressure regulation by the front gun pressure regulating valve 43.

[0079] like Figure 7 As shown, the present invention further provides a fire truck, which includes a fire truck body and the fire extinguishing system described in any one of the above embodiments, and the fire extinguishing system is arranged on the fire truck body.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
