[0025] A first aspect of the present application provides a vehicle-mounted foam fire extinguishing device 10, which is applied to a vehicle, and is particularly suitable for use in a new energy vehicle. Figure 1 It is a structural block diagram of an embodiment of the vehicle-mounted foam fire extinguishing device 10 provided in the present application.

[0026] Combination Figure 1 The vehicle-mounted foam fire extinguishing device 10 includes a water storage device 11 and a liquid storage device 12. The water storage device 11 is used to store water, and the liquid storage device 12 is used to store foam liquid. The water storage device 11 can be some water storage structures originally provided on the vehicle, such as a water tank of the vehicle. The water storage device 11 can also be completely independent of the original structure on the vehicle. In this case, the water storage device 11 can be installed in the vehicle by assembly, and no specific restrictions are made here. The foam liquid in the liquid storage device 12 is a foam liquid specially used for fire extinguishing, and the liquid storage device 12 is independent of the original structure of the vehicle.

[0027] The vehicle-mounted foam fire extinguishing device 10 also includes a mixing valve body 13, which has a water inlet 131, a liquid inlet 132 and a mixed liquid outlet 133. The water inlet 131 is connected to the water storage device 11, and the liquid inlet 132 is connected to the liquid storage device 12. The water introduced into the mixing valve body 13 is mixed with the foam liquid to form a mixed liquid. The mixed liquid outlet 133 is used to discharge the mixed liquid to achieve fire extinguishing.

[0028] Specifically, at this time, the mixing valve body 13 has a total of three ports, namely, a water inlet 131, a liquid inlet 132, and a mixed liquid outlet 133. The water inlet 131 can be directly connected to the water storage device 11 or indirectly connected through other structures, and no specific restrictions are made here. Similarly, the communication method between the liquid inlet 132 and the foam liquid storage device 12 can also be direct or indirect, and no specific restrictions are made here. After the water exported from the water storage device 11 and the foam liquid exported from the liquid storage device 12 enter the mixing valve body 13, they can be mixed in the mixing valve body 13 to form a mixed liquid. The mixed liquid obtained by mixing in the mixing valve body 13 will be further introduced into the fire location to achieve fire extinguishing.

[0029] In some specific application scenarios, the mixing valve body 13 may be a Laval mixing valve. Of course, it may also be other types of valve bodies, which are not specifically limited here.

[0030] The vehicle-mounted foam fire extinguishing device 10 also includes a regulating valve body 14, which is connected to the liquid storage device 12 and the liquid inlet 132 respectively. The regulating valve body 14 is used to introduce the foam liquid in the liquid storage device 12 into the mixing valve body 13. The regulating valve body 14 can adjust the flow rate of the foam liquid entering the mixing valve body 13 to adjust the proportion of the components of the mixed liquid.

[0031] Specifically, the regulating valve body 14 may have an inlet and an outlet, the inlet of the regulating valve body 14 is connected to the liquid storage device 12, and the outlet of the regulating valve body 14 is connected to the liquid inlet 132, so that the foam liquid in the liquid storage device 12 can be introduced into the mixing valve body 13 through the regulating valve body 14. Among them, the regulating valve body 14 can be a proportional valve, that is, it can adjust its own opening size, and then adjust the flow of the foam liquid entering the mixing valve body 13. Since the mixed liquid is composed of water and foam liquid, when the flow of the foam liquid changes, the ratio of water to foam liquid entering the mixing valve body 13 changes. It should be understood that by adjusting the ratio of the foam liquid, the mixed liquid can be adjusted to a mixed liquid with a better fire extinguishing effect, thereby achieving a good fire extinguishing effect.

[0032] In summary, through the setting of the mixing valve body 13, water and foam liquid can be mixed to form a mixed liquid, and then the mixed liquid can be used to extinguish the fire. Based on the setting of the regulating valve body 14, the flow of the foam liquid entering the mixing valve body 13 can be adjusted, and then the proportion of the foam liquid in the mixed liquid can be adjusted, and then the mixed liquid can be adjusted to a mixed liquid with a better fire extinguishing effect, thereby achieving a better fire extinguishing effect.

[0033] Continue to combine Figure 1 In some specific embodiments, the vehicle-mounted foam fire extinguishing device 10 further includes a first nozzle 151 and a second nozzle 152. The first nozzle 151 and the second nozzle 152 are both connected to the mixed liquid outlet 133. The outlets of the first nozzle 151 and the second nozzle 152 are respectively located in different preset areas of the vehicle to achieve fire extinguishing in the preset areas.

[0034] Specifically, the first nozzle 151 and the second nozzle 152 can be directly or indirectly connected to the mixed liquid outlet 133, so that the mixed liquid derived from the mixed liquid outlet 133 can enter the first nozzle 151 and the second nozzle 152, and then the first nozzle 151 and the second nozzle 152 can derive the mixed liquid into different preset areas. This embodiment only introduces the first nozzle 151 and the second nozzle 152, but the type of nozzle may be more than the first nozzle 151 and the second nozzle 152, for example, there may also be a third nozzle. Among them, the first nozzle 151 and the second nozzle 152 can be completely independent nozzles, or they can share some pipe sections.

[0035] Furthermore, in some specific embodiments, a first nozzle is provided at the liquid outlet end of the first nozzle 151, and a second nozzle is provided at the liquid outlet end of the second nozzle 152. The first nozzle can be provided on the door handle of the vehicle, and the second nozzle can be provided in the cabin of the vehicle. The first nozzle and the second nozzle are respectively used for spraying the mixed liquid.

[0036] Specifically, the first nozzle and the second nozzle can be a part of the first nozzle 151 and the second nozzle 152 respectively. The first nozzle and the second nozzle can be nozzles of the same type or nozzles of different types, and there is no specific limitation here. After the liquid in the first nozzle 151 is sprayed out through the first nozzle, the speed is increased, thereby achieving a better fire extinguishing effect. In some application scenarios, the first nozzle and the second nozzle can be Rafale nozzles, and the flow rate of the mixed liquid sprayed out from the first nozzle and the second nozzle is relatively high.

[0037] The first nozzle is arranged on the door handle of the vehicle, so that the mixed liquid sprayed by the first nozzle can directly extinguish the fire in the passenger compartment. The second nozzle is arranged in the engine compartment of the vehicle, so that the sprayed mixed liquid can directly extinguish the fire in the engine compartment. In the application scenario where more nozzles are arranged, the nozzles of more nozzles can be arranged in the trunk, thereby realizing the fire extinguishing in the trunk.

[0038] Continue to combine Figure 1 In some specific embodiments, the vehicle-mounted foam fire extinguishing device 10 also includes a first control valve 161 and a second control valve 162. The first control valve 161 is arranged on the first nozzle 151, and the second control valve 162 is arranged on the second nozzle 152. The first control valve 161 and the second control valve 162 are used to control the opening and closing of the first nozzle 151 and the second nozzle 152 respectively.

[0039] The first control valve 161 and the second control valve 162 may be the same control valve or different control valves, but both can realize the control of opening and closing the nozzle. When the control valve controls the first nozzle 151 to be closed, that is, the first nozzle 151 is controlled to be non-conductive, and the mixed liquid cannot be discharged from the first nozzle 151. Similarly, the second nozzle 152 is also the same.

[0040] Continue to combine Figure 1 In some specific embodiments, the vehicle-mounted foam fire extinguishing device 10 further includes a mixing device, which includes a first mixing zone 171 and a second mixing zone 172. The first mixing zone 171 and the second mixing zone 172 are separated by a mixing baffle 173, and the mixing baffle 173 is provided with a plurality of mixing equalizing holes. The mixing device has an inner cavity, which is divided into a first mixing zone 171 and a second mixing zone 172, and the size relationship between the first mixing zone 171 and the second mixing zone 172 can be set according to actual needs.

[0041] The mixed liquid outlet 133 is connected to the first mixing zone 171, and the mixed liquid in the first mixing zone 171 enters the second mixing zone 172 through the mixing equalizing hole, so that the mixed liquid is further mixed evenly, and the mixed liquid in the second mixing zone 172 is used to be discharged to achieve fire extinguishing. It should be understood that the degree of mixing between the water and the foam liquid in the mixed liquid introduced into the first mixing zone 171 by the mixing valve body 13 is not very high. After the mixed liquid in the first mixing zone 171 is introduced into the second mixing zone 172 through the mixing equalizing hole, the water and the foam liquid in the mixed liquid can be further mixed, thereby obtaining a more evenly mixed mixed liquid.

[0042] Continue to combine Figure 1In some specific embodiments, the mixing valve body 13 is disposed above the mixing device, and the liquid storage device 12 is disposed above the mixing valve body 13. The foam liquid in the liquid storage device 12 can be introduced into the mixing valve body 13 from the regulating valve body 14 by gravity. At this time, when the mixing valve body 13 is opened, the foam liquid in the liquid storage device 12 can be introduced into the mixing valve body 13 by gravity, which facilitates the mixing of the foam liquid and water. The mixed liquid can be introduced into the mixing device by gravity, specifically into the first mixing area 171.

[0043] Continue to combine Figure 1 In some specific embodiments, the outlet pipeline of the water storage device 11 is provided with a vertical pipe 111 (whose length is h), the bottom opening of the vertical pipe 111 is connected to the water inlet 131, and the top of the vertical pipe 111 is higher than the top of the liquid storage device 12. The outlet pipeline of the water storage device 11 is used to introduce water into the mixing valve body 13, and the vertical pipe 111 can be a part of the outlet pipeline or the whole of the outlet pipeline, which is not specifically limited here. When the vertical pipe 111 is a part of the outlet pipeline, the vertical pipe 111 is the end portion of the outlet pipeline.

[0044] Figure 2 yes Figure 1 A schematic structural diagram of an embodiment of the water storage device 11 in FIG.

[0045] The water storage device 11 includes a water tank 112, a water pump 113 and a water outlet pipe 114. The water pump 113 can output the water in the water tank 112 to the water outlet pipe 114. In combination with the above content, the water outlet pipe 114 can be directly connected to the vertical pipe 111, and then the water is introduced into the vertical pipe 111 through the water outlet pipe 114. At this time, a water outlet control valve 115 can be provided in the water outlet pipe 114, and the water outlet control valve 115 can control whether the water outlet pipe 114 is conductive or not.

[0046] It should be understood that, based on the arrangement of the vertical tube 111, the pressure of the foam liquid derived from the liquid storage device 12 increases when it enters the mixing valve body 13, so as to facilitate the mixing of the foam liquid and water. Since the top of the vertical tube 111 is higher than the top of the liquid storage device 12, the mixing effect between the foam liquid and water can be better.

[0047] In some specific embodiments, the vehicle-mounted foam fire extinguishing device 10 also includes a first temperature sensor (not shown) and a second temperature sensor (not shown). The first temperature sensor is disposed in the passenger compartment of the vehicle, and the first temperature sensor is used to detect the temperature in the passenger compartment. The second temperature sensor is disposed in the engine compartment of the vehicle, and the second temperature sensor is used to detect the temperature in the engine compartment.

[0048] In combination with the above, when the first temperature sensor detects a temperature higher than the preset temperature, it indicates that the passenger compartment is likely to catch fire, and at this time, the mixed liquid can be introduced into the passenger compartment through the first nozzle 151 to extinguish the fire in the passenger compartment. When the second temperature sensor detects a temperature higher than the preset temperature, it indicates that the cabin is likely to catch fire, and at this time, the mixed liquid can be introduced into the cabin through the second nozzle 152 to extinguish the fire in the cabin.

[0049] In some specific embodiments, the vehicle-mounted foam fire extinguishing device 10 includes a control device (not shown), which is connected to the regulating valve body 14, and is used to control the opening of the regulating valve body 14 to achieve flow regulation of the foam liquid entering the mixing valve body 13. In combination with the above content, the control device can also obtain the sensing information of the first temperature sensor and the second temperature sensor, and then obtain the temperature of the passenger compartment and the cabin, and then when it is determined that the passenger compartment or the cabin is on fire, the water storage device 11 is controlled to guide water and the liquid storage device 12 is controlled to guide foam liquid, and the opening of the regulating valve body 14 is controlled to control the composition ratio of the foam liquid. In addition, the control device also controls the first control valve 161 and the second control valve 162 to guide the mixed liquid into the corresponding fire area.

[0050] A second aspect of the present application provides a vehicle, which includes a vehicle-mounted foam fire extinguishing device 10 as described in any of the above embodiments.

[0051] In summary, the vehicle-mounted foam fire extinguishing device 10 and the vehicle provided by the present application include: a water storage device 11, which stores water; a liquid storage device 12, which stores foam liquid; a mixing valve body 13, which has a water inlet 131, a liquid inlet 132 and a mixed liquid outlet 133, the water inlet 131 is connected to the water storage device 11, and the liquid inlet 132 is connected to the liquid storage device 12, the water introduced into the mixing valve body 13 is mixed with the foam liquid to form a mixed liquid, and the mixed liquid outlet 133 is used to guide the mixed liquid to achieve fire extinguishing; a regulating valve body 14, which is respectively connected to the liquid storage device 12 and the liquid inlet 132, the regulating valve body 14 is used to introduce the foam liquid in the liquid storage device 12 into the mixing valve body 13, and the regulating valve body 14 can adjust the flow rate of the foam liquid entering the mixing valve body 13 to adjust the proportion of the components of the mixed liquid. Therefore, the water in the water storage device 11 and the foam liquid in the liquid storage device 12 can be mixed through the mixing valve body 13 to form a mixed liquid, and the component ratio of the mixed liquid can be adjusted by the regulating valve body 14, so that a mixed liquid with better fire extinguishing effect can be obtained to achieve fire extinguishing.
