[0002] The existing fire truck sprinkler self-protection system includes multiple nozzles, which are respectively installed in front of the cab and above each wheel. These nozzles are connected to the fire pump through suction pipes, and the nozzles are connected or disconnected from the fire pump through manual ball valves or butterfly valves, so as to achieve the purpose of spraying water from these nozzles to protect the cab and wheels.
[0003] Currently, when commercial vehicle chassis are used in fire truck applications, the vehicles cannot simultaneously operate the water pump while in motion; most chassis can only operate the water pump while parked. Therefore, in situations where fire trucks are traveling in high-temperature environments, on flowing fires, or need to immediately escape a fire, the vehicles cannot operate the water pump while in motion. Consequently, they cannot use the water from their own tanks to spray water mist onto the vehicle body and wheels to protect and cool the vehicle. Utility Model Content

[0035] The following describes in detail the overall structure, working principle, and technical effects of the fire truck spraying system 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0036] Please refer to Figure 1 The fire truck spraying system 010 provided by this utility model is applied to fire truck 100.
[0037] Among them, fire truck 100 can be water tanker fire truck 100, foam fire truck 100 or aerial ladder fire truck 100.
[0038] Please refer to Figures 1-2 The present invention provides a fire truck spraying system 010, including: a chassis 110, a drive pump 200 on the chassis 110, and a plurality of nozzles 150 at the bottom of the chassis 110;
[0039] Water tank 121 is located above chassis 110, and the output end of water tank 121 is connected to multiple nozzles 150 via drive pump 200;
[0040] The cab 130 is located above the chassis 110 and in front of the water tank 121. The cab 130 is equipped with a control module 300, which is connected to the drive pump 200. The control module 300 is used to control the drive pump 200 to pump fire-fighting water into the water tank 121.
[0041] Understandably, when 100 fire trucks are traveling in environments with high temperatures, or when 100 fire trucks are traveling on areas with flowing fires, or when it is necessary to immediately drive the vehicles out of the fire scene, the operator in the cab 130 can control the drive pump 200 through the control module 300, so that the drive pump 200 pumps the fire water in the water tank 121 to each nozzle 150, and each nozzle 150 sprays water to cool down the bottom of the chassis 110 or sprays water to extinguish the fire on the ground. This application, by installing a control module 300 inside the cab 130, allows the operator to control the drive pump 200 while the fire truck 100 is in motion. The operator does not need to get out of the vehicle to operate the drive pump 200, and it does not affect the fire truck 100's travel progress or speed, allowing the fire truck 100 to travel at full speed. By installing an independent drive pump 200 on the chassis 110, the drive pump 200 can pump fire water from the water tank 121 to each nozzle 150, enabling each nozzle 150 to spray sand and water mist onto the fire truck 100, protecting and cooling the vehicle. At the same time, this fire truck spraying system 010 has low installation cost, and the drive pump 200 and multiple nozzles 150 are all installed on the chassis 110, so various chassis 110 can be adapted to the drive pump 200 and multiple nozzles 150, making it highly versatile.
[0042] In this embodiment, please refer to Figure 1 The fire truck 100 includes a chassis 110, a cargo box 120 located above the chassis 110, a driver's cab 130, and wheels 140 located below the chassis 110. The driver's cab 130 is located at the front of the chassis 110, and the cargo box 120 is located at the rear of the chassis 110. The cargo box 120 is divided into a fire water tank area and an equipment area. The equipment area houses the supporting fire-fighting equipment, while the fire water tank area houses the equipped water tank 121. The drive pump 200 is mounted on the chassis 110.
[0043] The chassis 110 corresponds to the fire truck 100, which includes the left and right sides of the vehicle body.
[0044] The chassis 110 has at least four wheels 140 at its bottom, and the at least four wheels 140 are arranged symmetrically.
[0045] The chassis 110 has multiple nozzles 150 at its bottom.
[0046] In this embodiment, a drive pump 200 and a power supply unit 210 are mounted on the chassis 110. The power supply unit 210 is electrically connected to the drive pump 200 and is used to supply power to the drive pump 200. It is understood that using the power supply unit 210 built into the chassis 110 to drive the electric water pump ensures that the drive pump 200 does not consume engine power during operation, does not affect vehicle speed, and allows the vehicle to travel at full speed. Furthermore, since the drive pump 200 and multiple nozzles 150 are all mounted on the chassis 110, various chassis 110 can be adapted to the drive pump 200 and multiple nozzles 150, demonstrating strong versatility.
[0047] Optionally, the power supply unit 210 can be a battery.
[0048] In this embodiment, the driver's cab 130 may also be equipped with an operating unit adapted to the control module 300 to facilitate operation by the operator.
[0049] In this embodiment, please refer to Figure 3 The fire truck spraying system 010 includes an inlet valve 400.
[0050] The inlet valve 400 is connected to the output of the water tank 121, and the output of the inlet valve 400 is connected to the input of the drive pump 200. The inlet valve 400 is communicatively connected to the control module 300, which is also used to control the opening and closing of the inlet valve 400.
[0051] In this embodiment, please refer to Figure 3 The fire truck spraying system 010 also includes a water suction valve 500, the output end of which is connected to the input end of the drive pump 200, and the output end of the water suction valve 500 is connected to the water suction port 510.
[0052] Optionally, the suction valve 500 is communicatively connected to the control module 300 so that the control module 300 controls the opening and closing of the suction valve 500.
[0053] Understandably, the water intake 510 is connected to a water source via a pipeline, and can be used to replenish water tank 121 or to draw water for firefighting on site.
[0054] In this embodiment, the output end of the drive pump 200 is connected to multiple nozzles 150 through a pipeline structure, so that the control module 300 can perform zoned control of the nozzles 150, which can better cope with various emergency situations.
[0055] In this embodiment, please refer to Figure 3The bottom of the chassis 110 is provided with a first pipeline structure, the nozzle 150 includes a first nozzle 151, and multiple first nozzles 151 are provided on the first pipeline structure. The input end of the first pipeline structure is connected to the output end of the drive pump 200 through the body self-protection valve 600.
[0056] The vehicle body self-protection valve 600 is communicatively connected to the control module 300. The vehicle body self-protection valve 600 is used to independently open and close the first pipeline structure.
[0057] In this embodiment, the first pipeline structure is arranged along the bottom of the chassis 110 and relative to the left and right sides of the chassis 110 and the cab 130.
[0058] It is understandable that the first nozzles 151, located on the left and right sides of the chassis 110 and the cab 130 respectively, can cool the left and right sides of the chassis 110 and the cab 130 in separate zones, thereby ensuring the safety of the fire truck 100.
[0059] The first nozzle 151, located at the bottom of the cab 130, is angled to the direction of travel of the cab 130, with the first nozzle 151 facing the ground and the direction of travel of the cab 130. It is understood that the first nozzle 151 sprays water mist towards the front of the vehicle, creating a water mist protection for the cab 130, thereby protecting the components located in the cab 130 and the operator inside the cab 130.
[0060] In this embodiment, please refer to Figure 3 The bottom of the chassis 110 is provided with a second pipeline structure, the nozzle 150 includes a second nozzle 152, and multiple second nozzles 152 are provided on the second pipeline structure. The input end of the second pipeline structure is connected to the output end of the drive pump 200 through the wheel self-protection valve 700.
[0061] The wheel self-protection valve 700 is communicatively connected to the control module 300. The wheel self-protection valve 700 is used to independently open and close the second pipeline structure.
[0062] The chassis 110 has at least four wheels 140 at its bottom, and a second nozzle 152 is positioned close to the wheels 140. The second nozzle 152 forms an angle with the chassis 110 and is positioned towards the wheels 140.
[0063] Understandably, the second nozzle 152 sprays water onto each wheel 140 to cool the surface of the wheel 140 and extinguish any flowing fires on the ground where the wheel 140 is in contact with the ground, thereby preventing damage to the wheel 140 or tire blowouts and improving driving safety.
[0064] In this embodiment, multiple nozzles 150 are connected to the drive pump 200 through multiple switching valves 800, and the switching valves 800 are used to open or close the nozzles 150.
[0065] Among them, several switching valves 800 are normally open.
[0066] In this embodiment, the output end of the drive pump 200 is provided with a one-way valve 900, and the output end of the one-way valve 900 is connected to multiple switching valves 800.
[0067] Among them, the one-way valve 900 is normally open.
[0068] It is worth mentioning that the water suction valve 500, water inlet valve 400, body self-protection valve 600 and wheel self-protection valve 700 in the above embodiments can be pneumatic switch valves 800 or electric switch valves 800. The above valves using pneumatic switch valves 800 or electric switch valves 800 can communicate with the control module 300, and can then automatically open and close under the control of the control module 300.
[0069] The control module 300 can control the vehicle body self-protection valve 600 or the wheel self-protection valve 700 to open or close independently, thereby enabling targeted treatment of different fire situations and maximizing the utilization of water resources.
[0070] In summary, the fire truck spraying system 010 provided in this embodiment of the present invention, by installing a control module 300 in the cab 130, allows the operator to control the drive pump 200 to operate while the fire truck 100 is in motion. The operator does not need to get out of the vehicle to operate the drive pump 200, and it does not affect the driving progress and speed of the fire truck 100, allowing the fire truck 100 to travel at full speed. Furthermore, the drive pump 200 is independently installed on the chassis 110, and it can pump the fire water in the water tank 121 to each nozzle 150, so that each nozzle 150 sprays sand and water mist onto the fire truck 100 to protect and cool the vehicle. At the same time, the fire truck spraying system 010 has low installation cost, and the drive pump 200 and multiple nozzles 150 are all installed on the chassis 110, so various chassis 110 can be adapted to the drive pump 200 and multiple nozzles 150, making it highly versatile.
[0071] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
