Description

Technical Field

[0001] The present invention relates to the technical field of vehicle fire extinguishing, and particularly to a vehicle fire extinguishing device. Background Art

[0002] In related technologies, in scenarios such as parking and storage of vehicles and objects, spontaneous combustion fires account for a relatively high proportion. Especially for new energy electric vehicle fires, the fires occur suddenly and last for a long time. Currently, there are no effective fire extinguishing facilities and means, and the harm is great. Especially in underground, enclosed, and semi-enclosed spaces, there is a greater risk. In view of the thermal runaway mechanism of automobile batteries, traditional fire extinguishing media such as water-based, dry powder, and foam cannot quickly and effectively block thermal runaway. Currently, there is no dedicated high-efficiency fire extinguishing agent. When a spontaneous combustion accident occurs in a new energy vehicle, measures such as covering with a fire blanket and damming the fire are usually taken. Due to the limitations of the fire fighting conditions and operation difficulties at the fire scene, not only a large amount of fire water is required, but also the actual fire extinguishing effect is poor.

[0033] Next, reference is made to Figures 1 - 5 to describe a vehicle fire extinguishing device 100 according to an embodiment of the present invention.

[0034] As shown in Figure 1 and Figure 2As shown, a vehicle fire extinguishing device 100 according to an embodiment of the present invention includes an isolation chamber 10 and a seal 20. The isolation chamber 10 includes a chamber body 11 and a chamber door 12. The bottom of the chamber body 11 is open to form an opening 11a. An inlet / outlet 11b is provided on the side of the chamber body 11. The chamber body 11 is provided with a fire extinguishing medium inlet portion 111 for introducing a fire extinguishing medium into the chamber body 11 so that the fire extinguishing medium can be distributed in a set-height space within the chamber body 11. The chamber door 12 is movably provided on the chamber body 11 to open or close the inlet / outlet 11b. The seal 20 is provided on the isolation chamber 10 and is arranged around the opening 11a. The seal 20 has a first state and a second state. When the seal 20 is in the first state, it does not contact the ground. When the seal 20 is in the second state, it seals between the opening 11a of the chamber body 11 and the ground.

[0035] The fire extinguishing medium inlet portion 111 may refer to a structure capable of introducing a fire extinguishing medium. Exemplarily, the fire extinguishing medium inlet portion 111 may be a hole, a connector, a connection valve, etc. provided on the chamber body 11. For example, when the fire extinguishing medium inlet portion 111 is a fire hydrant connector, by connecting to a fire hydrant or a fire truck, direct injection fire extinguishing can be carried out on the vehicle 200. Among them, the fire extinguishing medium inlet portion 111 may be provided on any one of the multiple chamber walls of the isolation chamber 10, and there is no limitation here.

[0036] The seal 20 can be switched between the first state and the second state, thereby enabling flexible control of the state of the seal 20. When the seal 20 does not contact the ground in the first state, the friction between the chamber body 11 and the ground can be reduced when moving the chamber body 11, making it easier to move the chamber body 11, and it can also prevent damage to the seal 20 caused by frictional dragging with the ground. When the seal 20 contacts the ground in the second state, the seal 20 can play a sealing role at this time, sealing between the bottom of the isolation chamber 10 and the ground.

[0037] When a spontaneous combustion accident occurs to the vehicle 200 and the vehicle 200 is being extinguished, the inlet / outlet 11b of the chamber body 11 can be kept in an open state, so that the inlet / outlet 11b of the chamber body 11 can be pushed towards the vehicle 200. After the vehicle 200 completely enters the chamber body 11 (see Figure 6) The storage door 12 can be closed to seal the inlet / outlet 11b. Then, the seal 20 switches from the first state to the second state to seal between the opening 11a of the storage body 11 and the ground. Thus, a closed state is achieved between the periphery of the storage body 11 and the ground, and the isolation chamber 10 can form an approximately airtight or airtight fireproof box. The fire extinguishing medium inlet 111 is connected to a fire extinguishing medium delivery device to introduce the fire extinguishing medium into the isolation chamber 10. As the fire extinguishing medium is continuously fed in, finally the fire extinguishing medium is in a set height space inside the storage body 11, so that the battery pack encapsulated at the bottom of the vehicle 200 is completely immersed in the fire extinguishing medium. This can enable the fire extinguishing medium to fully contact the battery pack at the bottom of the vehicle 200, and the contact time is longer, which can enhance the fire extinguishing effect and improve the fire extinguishing efficiency.

[0038] Among them, the above-mentioned "fire extinguishing medium delivery device" can be, but is not limited to, devices such as fire hydrants, fire trucks, etc. that can deliver fire extinguishing medium.

[0039] "The fire extinguishing medium is in a set height space inside the storage body 11" can mean that the fire extinguishing medium can maintain a certain height inside the isolation chamber 10. For example, it can be the height that completely immerses the battery pack at the bottom of the vehicle 200, or the height at half of the vehicle 200, or the height that completely immerses the vehicle 200. There is no limit here.

[0040] Since the isolation chamber 10 can isolate the self-igniting vehicle 200 from the outside world and extinguish the fire inside the isolation chamber 10, this can avoid damage to the surrounding rescue personnel caused by the high temperature, hot air flow or flame when the vehicle 200 self-ignites, and can reduce the safety hazards of rescue. Moreover, the bottom of the isolation chamber 10 can be sealed with the ground through the seal 20, which can also prevent the high temperature, hot air flow or flame caused by self-ignition from leaking out from the bottom of the isolation chamber 10, and further prevent damage to the rescue personnel caused by the hot air flow or flame. It can be seen that using the vehicle fire extinguishing device 100 can improve the rescue safety while achieving efficient fire extinguishing.

[0041] In the above technical solution, the isolation chamber 10 can also quickly isolate the self-igniting vehicle 200, which is beneficial to achieving rapid rescue and fire extinguishing. This can ensure the timeliness of fire extinguishing, reduce the fire extinguishing time, and further avoid the situation where the vehicle 200 is completely burned out, and can protect the vehicle 200 as much as possible and reduce property losses. Since the battery pack contains chemical substances and will produce toxic and harmful gases when burning, and other components of the vehicle 200 will also produce toxic and harmful gases when burning, using the isolation chamber 10 to surround the vehicle 200 for fire extinguishing and sealing the bottom of the isolation chamber 10 through the seal 20 can also prevent the toxic and harmful gases from spreading to the surrounding area, and can also ensure the safety of rescue personnel and the surrounding people.

[0042] On the other hand, when using the above-mentioned vehicle fire extinguishing device 100 to extinguish the fire of the vehicle 200, since the vehicle 200 and the fire extinguishing medium are isolated in the isolation chamber 10, the fire extinguishing medium will form contaminated waste after contacting the battery pack. Taking the fire extinguishing medium as water as an example, the fire-fighting water after extinguishing the fire will be harmful. By isolating the fire extinguishing medium in the isolation chamber 10, it can also prevent the fire extinguishing medium from spreading into the surrounding environment and polluting the objects, people or underground water resources in the surrounding environment.

[0043] According to the vehicle fire extinguishing device 100 of the embodiment of the present invention, the isolation chamber 10 can quickly isolate the vehicle 200 from the outside for enclosed fire extinguishing, which is convenient for quickly carrying out fire extinguishing. And through the seal 20, the bottom of the isolation chamber 10 and the ground can be sealed, so that the fire extinguishing medium can be maintained in the set height space in the isolation chamber 10, thereby realizing the immersion fire extinguishing of the bottom or the whole of the vehicle 200, which is beneficial to improving the fire extinguishing effect, as well as improving the fire extinguishing efficiency, and can also reduce the consumption of the fire extinguishing medium and save costs. Adopting the above solution can also control the fire source in a relatively enclosed space, effectively prevent the high temperature, hot air flow or flame generated by the spontaneous combustion of the vehicle 200 from damaging the rescue personnel, and improve the rescue safety.

[0044] In some embodiments of the present invention, as Figures 2 to 4 shown, the seal 20 is configured to be movable in the up and down direction of the isolation chamber 10. A cavity is formed inside the seal 20, and the cavity is arranged around the circumference of the opening 11a. The seal 20 is provided with a filler inlet communicating with the cavity, and the filler inlet is used to put in a filler so that the seal 20 can be switched from the first state to the second state.

[0045] When no filler is placed in the cavity of the seal 20, the overall weight of the seal 20 is relatively light and it may not contact the ground (see Figure 2 ), when the filler is put into the cavity of the seal 20 through the filler inlet, the seal 20 can contact the ground under the action of gravity to achieve the sealing effect (see Figure 3 ). The seal 20 can be, but is not limited to, a rubber material part, a woven bag or a leather bag, etc. When the seal 20 is a rubber material part or a leather bag, the filler can be, but is not limited to, water, flame retardant liquid, gravel, sand and stone, etc.; when the seal 20 is a woven bag, the filler can be, but is not limited to, gravel, yellow sand or soil, etc.

[0046] It should be noted that the seal 20 can include two seal segments. One of the two seal segments can be arranged on the three lateral walls of the chamber body 11, and the other is separately arranged on the chamber door 12, so that while realizing the function of opening or closing the chamber door 12, it can ensure that the whole seal 20 can achieve the sealing effect on the bottom of the isolation chamber 10.

[0047] In the above technical solution, the seal 20 is moved up and down by placing a filler, so that the seal 20 can be switched between the first state and the second state. This method is simpler and more reliable, facilitating repeated use and having a relatively low operation difficulty.

[0048] In some embodiments of the present invention, such as Figure 3 and Figure 4 shown, the seal 20 is a water bag with an elastic contraction function. In this technical solution, the filler of the water bag can be fire-fighting water, so that the water bag can form a water-blocking and heat-insulating cofferdam around the isolation chamber 10, having a good sealing and fire-resistant effect. Moreover, water is convenient to use as a filler, the structure of the water bag is simple, and the cost is relatively low, which can save costs.

[0049] In some embodiments of the present invention, the seal 20 can be a non-cavity structure and can be driven by a driving member to be switched between the first state and the second state. For example, the driving member can be a linear motor or a telescopic cylinder, etc., and is arranged in a plurality along the circumferential direction of the isolation chamber 10. The plurality of driving members can drive the seal 20 to move in the vertical direction, so that when it is necessary to seal the opening 11a of the cabin body 11 and the ground, the seal 20 can be driven to be pressed against the ground, and when it is not necessary to seal the opening 11a and the ground, the seal 20 can be driven to be lifted upward.

[0050] In some embodiments of the present invention, such as Figures 2 to 4 shown, the vehicle fire extinguishing device 100 includes a heat-insulating and waterproof member 30 and a retracting and releasing mechanism. The heat-insulating and waterproof member 30 is provided on the isolation chamber 10 and is arranged around the opening 11a in a ring shape; the retracting and releasing mechanism is provided on the isolation chamber 10 and is configured to retract or release the heat-insulating and waterproof member 30, wherein when the heat-insulating and waterproof member 30 is released, it can contact the ground.

[0051] The heat-insulating and waterproof member 30 can not only play a heat-insulating role, isolating the high temperature, hot air flow or flame formed by the spontaneous combustion of the vehicle 200 from being transmitted to the cabin body 11, reducing the requirement for the fire-resistant and heat-insulating performance of the cabin body 11, which is beneficial to reducing the manufacturing cost of the cabin body 11, but also can effectively block the damage caused by high temperature to rescue personnel. The heat-insulating and waterproof member 30 can also play a waterproof role, so that it can prevent the fire-fighting water from flowing outwards when the fire extinguishing medium is fire-fighting water. That is to say, the heat-insulating and waterproof member 30 and the seal 20 can play a double-sealing role, further improving the sealing performance around the isolation chamber 10 and providing a more stable fire extinguishing medium immersion condition for the battery pack at the bottom of the vehicle 200. The heat-insulating and waterproof member 30 can be, but is not limited to, a heat-insulating and waterproof cloth, a heat-insulating and waterproof film, etc.

[0052] The retracting and deploying mechanism can serve to retract or deploy the heat insulation and waterproof member 30. In this way, when fire extinguishing is not required, the heat insulation and waterproof member 30 is retracted, and when fire extinguishing is required, the heat insulation and waterproof member 30 is deployed, which can reduce the influence of the heat insulation and waterproof member 30 on the movement of the isolation chamber 10. The retracting and deploying mechanism can be, but is not limited to, a clamping device, a winding device, a pulling device, and the like.

[0053] For example, if the heat insulation and waterproof member 30 is a heat insulation and waterproof cloth, the retracting and deploying mechanism can be a reel with independent power. In the normal state, the reel rolls up the heat insulation and waterproof cloth, and when the heat insulation and waterproof cloth is needed, the reel rotates in reverse to release the heat insulation and waterproof cloth.

[0054] In some embodiments of the present invention, the heat insulation and waterproof member 30 can include a plurality of heat insulation and waterproof segments. The number of heat insulation and waterproof segments can be, but is not limited to, two, three, four, and the like. For example, there are two heat insulation and waterproof segments. One is arranged along the left side wall, the front chamber wall, and the right side wall of the chamber body 11, and the other is arranged on the chamber door 12. One or more retracting and deploying mechanisms are respectively provided for the two heat insulation and waterproof segments. The heat insulation and waterproof segments can also be four, which are respectively arranged on the left chamber wall, the front chamber wall, the right chamber wall, and the chamber door 12 of the chamber body 11, and one or more retracting and deploying mechanisms are provided for each heat insulation and waterproof segment. Among them, the bottoms of any two adjacent heat insulation and waterproof segments can be arranged in a cross-overlapping manner, thereby ensuring the sealing between two adjacent heat insulation and waterproof segments and reducing the risk of leakage of the fire extinguishing medium.

[0055] In some embodiments of the present invention, as Figures 2 to 4 shown, the circumferential chamber wall of the isolation chamber 10 is provided with an accommodation space 10a, and the heat insulation and waterproof member 30 and the retracting and deploying mechanism are arranged in the accommodation space 10a. The accommodation space 10a can serve to accommodate the heat insulation and waterproof member 30 and the retracting and deploying mechanism, which can reduce the influence of the retracting and deploying mechanism by high temperature, hot air flow, flame, etc., reduce the high temperature resistance requirement for the retracting and deploying mechanism, be conducive to ensuring that the retracting and deploying mechanism can maintain normal operation, and also make the overall structure of the vehicle fire extinguishing device 100 more compact, and ensure that there is a larger space inside to place the vehicle 200 when the overall size of the isolation chamber 10 is relatively small. Secondly, the accommodation space 10a makes the heat insulation and waterproof member 30 and the retracting and deploying mechanism not exposed outside, which can reduce the damage caused by mechanical impact and is conducive to extending the service life of the heat insulation and waterproof member 30 and the retracting and deploying mechanism.

[0056] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the heat insulation and waterproof member 30 is arranged on the inner side of the chamber body 11, and the sealing member 20 is arranged on the outer side of the chamber body 11; the vehicle fire extinguishing device 100 includes a support mechanism 40, and the support mechanism 40 is arranged between the heat insulation and waterproof member 30 and the chamber wall of the chamber body 11 and can be deployed or retracted.

[0057] The heat insulation and waterproof member 30 and the seal member 20 can play a sealing role on both the inner and outer sides of the bin body 11. On the one hand, it reduces the position interference and mutual influence during the arrangement of the heat insulation and waterproof member 30 and the seal member 20, which is beneficial to the arrangement of the heat insulation and waterproof member 30 and the seal member 20. On the other hand, it also facilitates the operation of the seal member 20, such as placing fillers inside the seal member 20 and realizing the switching between the first state and the second state of the seal member 20.

[0058] When the fire extinguishing medium is liquid, the inner side of the heat insulation and waterproof member 30 close to the vehicle 200 is a liquid environment. The support mechanism 40 can support the heat insulation and waterproof member 30 to prevent the liquid from squeezing the heat insulation and waterproof member 30 to expand outward. This is beneficial to making the space enclosed by the heat insulation and waterproof member 30 have a shape that is narrower at the bottom and wider at the top, which is beneficial to reducing the consumption of the fire extinguishing medium and lowering the cost. For example, when the fire extinguishing medium is fire-fighting water, this method can reduce the water consumption and save water resources.

[0059] In some embodiments of the present invention, as Figure 4 shown, the support mechanism 40 can be a support plate that can be pivotally lifted or lowered. The support mechanism 40 can rotate upward to lift and support the heat insulation and waterproof member 30, and when the heat insulation and waterproof member 30 does not need to be supported, the support mechanism 40 can rotate downward and retract. Among them, the support plate can refer to being manually opened or retracted mechanically, or being electrically assisted to open or retract, which is not limited here.

[0060] In some embodiments of the present invention, as Figures 1 to 3 、 Figure 5 and Figure 6 shown, the bin body 11 has a plurality of side bin walls 112 arranged around the opening 11a. The side bin walls 112 and the bin door 12 are both provided with heavy object dropping openings. There are a plurality of heavy object dropping openings on the side bin walls 112 and the bin door 12, and each heavy object dropping opening is provided with an openable or closable switch door 13.

[0061] The plurality of side bin walls 112 can refer to the side plates enclosing the bin body 11. Taking the bin body 11 as a rectangular box as an example, the plurality of side bin walls 112 can refer to the left bin wall, the front bin wall and the right bin wall. The "heavy objects" referred to in the heavy object dropping openings can be, but are not limited to, sand, bricks or mud bags, etc. Among them, the number of the switch doors 13 is equal to and corresponds one by one to the number of the heavy object dropping openings.

[0062] In the above technical solution, when the heat insulation and waterproof member 30 is released and surrounds the opening 11a for one week, the heavy object dropping openings on the side bin walls 112 and the bin door 12 can be opened by opening the switch doors 13, and heavy objects can be dropped into the isolation bin 10. When the heat insulation and waterproof member 30 is a heat insulation and waterproof cloth or a heat insulation and waterproof film, the heavy objects can press the bottom of the heat insulation and waterproof member 30, thereby pressing the heat insulation and waterproof member 30 tightly on the ground and enhancing the sealing and heat insulation effects of the heat insulation and waterproof member 30 on the bottom of the isolation bin 10.

[0063] In some embodiments of the present invention, as Figures 1 to 5 shown, the storage body 11 is provided with a traveling mechanism 14. The traveling mechanism 14 can be, but is not limited to, traveling wheels, a traveling chassis, etc. The traveling wheels can be universal wheels, caster wheels, etc., and the traveling chassis can refer to a chassis device with electric driving force for traveling.

[0064] It can be understood that by providing the traveling mechanism 14 on the storage body 11, the difficulty of moving the storage body 11 to cover the vehicle 200 can be reduced. Using a traveling chassis can save manpower and is also beneficial for realizing remote control or remote operation.

[0065] In some embodiments of the present invention, the fire extinguishing medium introduced by the fire extinguishing medium inlet 111 is one of gaseous, liquid, and powdery. It can be understood that when fire-fighting and extinguishing the vehicle 200, the fire extinguishing medium submerging the battery pack at the bottom of the vehicle 200 can be water, gas, or powder with a certain height. Among them, the gas can be, but is not limited to, carbon dioxide, heptafluoropropane, inert gas (such as nitrogen or argon), etc., and the powder can be, but is not limited to, dry powder, aerosol, etc.

[0066] In some embodiments of the present invention, as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the vehicle fire extinguishing device 100 includes a spraying mechanism 50. The spraying mechanism 50 is provided on the storage body 11 and is used to spray the fire extinguishing medium into the storage body 11.

[0067] The spraying mechanism 50 can refer to a mechanism that can spray the fire extinguishing medium, such as a spray pipe, a spray head, etc. The spraying mechanism 50 can be provided at the top of the storage body 11, on the side, or at both the top and the side of the storage body 11.

[0068] It can be understood that the vehicle fire extinguishing device 100 can not only submerge the bottom battery pack of the vehicle 200 with the fire extinguishing medium in the isolation chamber 10 to maintain a set height space for fire extinguishing, but also spray the fire-fighting medium to the top of the vehicle 200 through the spraying mechanism 50, so as to play a more comprehensive fire extinguishing role, improve the fire extinguishing effect, and improve the fire extinguishing efficiency.

[0069] In some embodiments of the present invention, the top of the storage body 11 is an open structure, or the top of the storage body 11 is a closed structure.

[0070] It can be understood that the top of the storage body 11 can be completely open or designed with a hollow structure. Using this structure can quickly release the high temperature, hot air flow, flame, etc. generated during the spontaneous combustion of the vehicle 200 upward into the external environment, which is beneficial for reducing the load on the isolation chamber 10, lowering the high temperature resistance and fire prevention requirements for the isolation chamber 10, and thus reducing costs.

[0071] The top of the storage body 11 may also have a top storage wall, which can completely isolate the high temperature, hot air flow or flame generated by the self-ignition of the vehicle 200 from the outside world, reducing the impact on the surrounding environment. Especially when the vehicle 200 self-ignites in an indoor environment such as an underground garage, the top of the storage body 11 is a closed structure, so that the overall isolation chamber 10 and the ground form a fully enclosed structure, which can prevent the high temperature, hot air flow or flame from damaging the objects in the surrounding environment and is conducive to avoiding the occurrence of secondary fire risks.

[0072] In some embodiments of the present invention, as Figures 1 to 3 shown, the isolation chamber 10 is provided with a discharge mechanism 15, and the discharge mechanism 15 is used to discharge the fire extinguishing medium in the storage body 11 to the waste recycling mechanism.

[0073] It can be understood that the discharge mechanism 15 can be but is not limited to a waste discharge valve, a suction device, etc. For example, when the discharge mechanism 15 is a waste discharge valve, after the fire extinguishing is completed, the fire extinguishing medium can be directly discharged into the waste recycling mechanism by opening the waste discharge valve. When the discharge mechanism 15 is a suction device, the fire extinguishing medium can be sucked into the waste recycling mechanism. Among them, the waste recycling mechanism can be a recycling tank, a waste recycling vehicle, etc. The discharge mechanism 15 can be provided on the storage body 11 or on the storage door 12. When the discharge mechanism 15 is provided on the storage body 11, it can be provided on the top or side of the storage body 11.

[0074] For example, when the fire extinguishing medium is water, the discharge mechanism 15 can be a water pump, and the waste recycling mechanism can be a waste water collection vehicle. The waste water inside the isolation chamber 10 can be pumped into the waste water collection vehicle by the water pump, and then the waste water collection vehicle transports the waste water to the sewage treatment plant for treatment.

[0075] In the above technical solution, the waste after the fire extinguishing can be discharged from the isolation chamber 10 by the discharge mechanism 15 and discharged to the waste recycling mechanism, so as to realize the recycling of the fire extinguishing medium and prevent the fire extinguishing medium from causing secondary pollution to the surrounding environment.

[0076] In some embodiments of the present invention, the storage door 12 can be but is not limited to a flip door, a vertical sliding door or a rolling shutter door provided on the storage body 11, etc.
