Description

Background Art

[0002] In the current new energy vehicle field, the safety of new energy vehicle batteries has always received special attention. Due to the inherent characteristics of lithium-ion batteries currently used in new energy vehicles, fires are often accompanied by high-temperature jet fires, toxic and harmful smoke eruptions, etc., which are extremely harmful. At present, once a battery pack has a thermal runaway fire, the existing firefighting measures are difficult to extinguish the open flames generated by the battery pack, and it is very easy to reignite after extinguishing, causing secondary disasters. In scenarios such as new energy vehicle charging stations, new energy vehicle storage yards, and new energy vehicle roll-on / roll-off ships, once a fire occurs, it is very easy for the fire to spread between vehicles, causing greater harm and economic losses.

[0003] Existing fire-fighting measures for new energy vehicles mainly rely on fire-fighting pipe spraying and firefighters' water guns to extinguish fires. They are often unable to extinguish the open flames in the battery pack and can only wait for the entire vehicle and other surrounding vehicles to burn out. This method of fire-fighting not only has little effect on new energy vehicle fires, but the harmful substances sprayed from the battery cause great harm to the health of firefighters. The harmful substances such as electrolytes mixed in the wastewater of spraying fire extinguishing will also cause serious harm to the environment.

[0004] The above problems make it impossible for existing fire-fighting equipment to effectively extinguish fires of new energy vehicles, which is an urgent problem to be solved in the safety assurance link of new energy vehicles. Summary of the invention

[0005] The purpose of the present invention is to provide a new energy vehicle immersion fire extinguishing and heat insulation fire protection system and method suitable for multiple scenarios, which can effectively extinguish new energy vehicle fires through immersion fire extinguishing, reducing harm to the human body and the environment. The adopted technical solutions are as follows:

[0006] A new energy vehicle immersion fire extinguishing and heat insulation fire protection system suitable for multiple scenarios, including:

[0007] The bottom plate 2 is laid on the parking space, and the upper surface thereof is provided with mounting grooves connected end to end. The area surrounded by the mounting grooves is used to carry the parked vehicles, and a liquid injection port 17 is provided on the bottom plate;

[0008] The bottom surface of the bottom plate 2 is provided with a groove for laying a liquid inlet pipe, and the groove extends to the edge of the bottom plate 2; one end of the liquid inlet pipe is connected to the liquid injection port 17, and the other end extends to the outside of the bottom plate 2;

[0009] And the fire extinguishing water pool 3 is made of flexible material, which is a closed structure connected end to end, fixedly connected to the inner bottom surface of the installation groove, and laid in the installation groove before inflation; the air inlet of the fire extinguishing water pool is connected to the inflation component.

[0010] Preferably, it further includes a cover plate assembly, which covers the mounting groove before inflation, and includes: a front cover plate 4, a right cover plate 6, a rear cover plate 5 and a left cover plate 7 arranged in sequence along the mounting groove, all of which are hinged to the bottom plate 2 by hinges, and all cover the sub-groove sections corresponding to the mounting groove before inflation.

[0011] Preferably, the inflatable component comprises:

[0012] The compressed gas cylinder 9 is placed in a protective groove provided on the bottom plate 2;

[0013] A pipeline connects the compressed gas cylinder 9 and the air inlet of the fire extinguishing pool 3; a connecting valve 8 is arranged on the pipeline.

[0014] Preferably, the fire extinguishing pool 3 is made of fire-resistant and waterproof material.

[0015] Preferably, a fire-fighting device is also included, which specifically includes: a fire-proof rolling shutter box 14 and a fire-proof rolling shutter 15;

[0016] The fireproof shutter box 14 comprises:

[0017] The box body is fixed to the parking space ceiling 11, and its lower end surface is open;

[0018] At least one movable baffle, one end of which is hinged to the inner wall of the box body and the other end is connected to the output end of the cylinder, and the movable baffle is distributed along the inner wall of the box body;

[0019] The fireproof rolling curtain 15 is located in the box body and is a structure connected end to end with its lower end face open. The fireproof rolling curtain is placed on the movable baffle and its upper end is fixed to the top of the box body. Before the fireproof rolling curtain box 14 is started, the lower end of the fireproof rolling curtain is placed on the movable baffle.

[0020] A new energy vehicle immersion fire extinguishing and heat insulation fire fighting method suitable for multiple scenarios, based on the new energy vehicle immersion fire extinguishing and heat insulation fire fighting system for multiple scenarios, comprises the following steps:

[0021] Inflate the fire extinguishing pool 3 to raise the immersion fire extinguishing pool 3. After the fire extinguishing pool 3 is inflated, the front cover plate 4, the rear cover plate 5, the right cover plate 6 and the left cover plate 7 are pushed open. When the inflation is completed, the fire extinguishing pool 3 rises to the upper edge of the wheel;

[0022] The fire extinguishing liquid is injected into the fire extinguishing pool 3 to perform immersion fire extinguishing.

[0023] Preferably, the method further comprises the following steps:

[0024] The release switch 19 is manually activated, and the control unit controls the cylinder in the fire-proof roller shutter box 14 to retract, so as to lower the fire-proof roller shutter 15, thereby forming a partition in front, behind, left and right of the vehicle on fire.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. Parking space pads can be installed on the original parking spaces without civil engineering modifications, such as ordinary parking spaces, new energy vehicle charging spaces, new energy vehicle storage spaces, car roll-on / roll-off ship spaces, etc., and can be used to immerse and extinguish fires in faulty new energy vehicles, isolate oxygen, absorb heat, and lower the temperature, fully suppressing and extinguishing fires in new energy vehicle battery packs.

[0027] In addition, the immersion fire extinguishing liquid and water pool can absorb the impact of thermal runaway jet fire or explosion of the single battery in the vehicle battery pack to protect the safety of surrounding people and property; the wastewater accumulated in the pool after immersion fire extinguishing can be collected and treated before discharge to avoid the pollution of the environment by harmful substances in the battery to protect the environment. This solves the problem that traditional fire-fighting measures cannot fully extinguish fires in new energy vehicles and increases the safety of new energy vehicles.

[0028] 2. Fire-fighting devices, in conjunction with the parking pad in the present invention, can add a protective measure on the basis of immersion fire extinguishing. When the fire of a new energy vehicle cannot be controlled, the fire-insulating and heat-insulating fire-fighting device can form a barrier around the burning vehicle to isolate the open flame and the heat of the flame from being transmitted to adjacent vehicles or related personnel and equipment. Avoid the spread of the fire, reduce the fire hazard, and reduce the disaster loss.

[0029] 3. Wide range of application scenarios.

[0030] The parking space pad 1 can be placed in the existing parking space without any damage without any civil engineering modification to the existing new energy charging parking space, and can immerse and extinguish the fire of the new energy vehicle parked above it, fully suppressing and extinguishing the fire of the battery pack of the new energy vehicle. In combination with the fire fighting device provided by the present invention, it can effectively prevent the fire from spreading to the adjacent charging pile equipment and adjacent parked vehicles, reduce the fire hazard, reduce the disaster loss, and increase the safety of new energy vehicles.

[0031] The parking space pad 1 can be directly installed on the trailer platform of the existing road rescue vehicle, and can be used to immerse and extinguish the fire of the faulty new energy vehicle being rescued above it when necessary, so as to fully suppress and extinguish the fire of the battery pack of the new energy vehicle. It can effectively prevent the fire from spreading to the road rescue vehicle and protect the property safety of the road rescue personnel. It can reduce the fire hazards, reduce the disaster losses, and increase the safety of new energy vehicles.

[0032] The present invention can be applied to existing car ro-ro ships. The parking space pad 1 can be placed on the deck parking space without rebuilding the deck of the new energy ro-ro ship, and the faulty new energy vehicle parked above it can be immersed and extinguished to fully suppress and extinguish the fire of the battery pack of the new energy vehicle. In conjunction with the fire-fighting device installed above the parking space, it can effectively prevent the fire from spreading to adjacent parked vehicles, prevent the fire from spreading in the cabin, and cause the entire ship to catch fire. Thereby reducing the fire hazard, reducing the disaster loss, and increasing the safety of new energy vehicles.

[0033] 4. The parking space pad and the fire-fighting device work together. When the parking space pad operates independently, the new energy vehicle above it that has a fault and caught fire can be immersed in fire extinguishing. It is suitable for scenarios including but not limited to new energy vehicle charging stations, new energy vehicle road rescue, new energy vehicle transportation, etc.

[0034] Compared with other fire-fighting facilities, the fire-fighting effect of the present invention is better and the implementation cost is lower, which solves the pain point that the current traditional fire-fighting measures cannot effectively extinguish the fire of new energy vehicles; when the parking pad and the fire-fighting device work together, the fire-fighting device acts as a redundant design of immersion fire-fighting. When the immersion fire-fighting effect is not good, the fire-fighting device starts and forms a barrier to prevent the open flame and heat radiation from spreading to nearby personnel and equipment, adding a protective measure on the basis of immersion fire-fighting. The fire-fighting capacity of the immersion fire-fighting and heat-insulating fire-fighting equipment for new energy vehicles suitable for multiple scenarios of the present invention is increased, further reducing fire hazards and reducing disaster losses.

[0057] The following will be combined with a schematic diagram to describe in more detail the new energy vehicle immersion fire extinguishing and heat insulation fire protection system and method applicable to multiple scenarios of the present invention, wherein the preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0058] Example 1

[0059] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 In a first aspect, the present invention provides a parking space pad 1, a fire-extinguishing parking space pad 1, which can be placed in an existing parking space without damage without performing civil engineering modifications on the existing parking space. The parking space in this embodiment is a new energy vehicle charging space.

[0060] like Figure 1 , Figure 2 As shown, the new energy vehicle submerged fire-fighting parking space pad 1 consists of a bottom plate 2 as a mounting base for other components, providing a mounting position for other components and supporting the parked vehicles above.

[0061] Among them, the parking space pad 1 is an immersion fire-fighting parking space pad for new energy vehicles.

[0062] like Figure 2 , Figure 3 As shown, an inflatable immersible fire extinguishing water pool 3 made of fire-resistant and waterproof material is provided in the upper surface groove (installation groove) of the base plate 2. The immersible fire extinguishing water pool 3 is annular in shape, and its bottom is sealedly connected to the base plate 2. After inflation, an uncovered box body is formed with the base plate 2 as the bottom and the fire extinguishing water pool 3 as the side, thereby forming a container to constitute a complete water pool.

[0063] The fire extinguishing water pool 3 is folded in the upper surface groove of the base plate 2 in the normal state (unaerated state), and is covered and protected by the front cover plate 4, the rear cover plate 5, the right cover plate 6 and the left cover plate 7. The aforementioned four cover plates are installed on the base plate 2 through rotating hinges, covering the unaerated fire extinguishing water pool 3 to protect it from being crushed and worn by parked vehicles.

[0064] When the fire extinguishing pool 3 is inflated and raised, the front cover plate 4, the rear cover plate 5, the right cover plate 6 and the left cover plate 7 are pushed up by the fire extinguishing pool 3 and rotated to open, thereby releasing the fire extinguishing pool 3.

[0065] like Figure 4 As shown, a connecting valve 8 is connected to the pipeline between the fire extinguishing pool 3 and the compressed gas cylinder 9. The connecting valve 8 is connected to the signal of the inflation switch 18 through the control unit. After the connecting valve 8 is opened by the inflation switch 18, the compressed gas in the compressed gas cylinder 9 can be injected into the fire extinguishing pool 3, so that the fire extinguishing pool 3 is inflated and raised.

[0066] The compressed gas cylinder 9 is placed in a protective groove provided on the bottom plate 2. Fig.14 shown.

[0067] The pipeline is placed in the protection groove, extends to the installation groove and then connected to the fire extinguishing water pool 3, and a protection cover 10 is arranged on the protection groove.

[0068] Specifically, the inflation switch 18 is connected to the connection valve 8 through the control unit. That is, the inflation switch 18 and the connection valve 8 (Q641F-16P) are both connected to the control unit signal.

[0069] After the fire extinguishing pool 3 is inflated, the front cover plate 4, the rear cover plate 5, the right cover plate 6 and the left cover plate 7 are pushed open, and the inflation is completed and the pool rises to at least the height of the upper edge of the wheel; at the same time, a liquid filling port 17 is provided in the center of the upper surface of the bottom plate 2 (facing the position of the battery pack), and the fire extinguishing liquid (water or fire fighting liquid) injected through the liquid filling port 17 completely immerses the battery pack of the new energy vehicle with thermal runaway to perform immersion fire extinguishing.

[0070] See also Figure 5 , Figure 6 , Figure 7 , Figures 8(a) to 8(c) In the second aspect, the present invention provides a fire-fighting device (fire-insulating fire-fighting device for parking spaces of new energy vehicles), the fire-insulating fire-fighting device comprising a fire-insulating rolling shutter box 14 and a fire-insulating rolling shutter 15, the fire-insulating rolling shutter box 14 being installed on the lower surface of the open-air parking space ceiling 11. The parking space ceiling support column 2 13 connects the parking space ceiling support column 1 12 and the parking space ceiling 11.

[0071] like Figures 5 to 9 As shown, the fireproof roller shutter box 14 includes a fireproof roller shutter 15, which is made of heat-insulating and fire-insulating cloth. Normally (in a retracted state), it is folded and placed in the fireproof roller shutter box 14, and can be triggered to release by a release switch 19.

[0072] Specifically, the structure of the fireproof shutter box 14 is as follows:

[0073] The fire shutter box 14 comprises:

[0074] The box body is fixed to the lower surface of the parking space ceiling 11, and its lower end surface is open;

[0075] At least one movable baffle, one end of which is hinged to the inner wall of the box body and the other end is connected to the output end of the cylinder, and the movable baffles are distributed along the inner wall of the box body; preferably, before the fire-proof rolling curtain is released, the movable baffles are in contact with each other, and all the movable baffles form a closed plane;

[0076] The fireproof rolling curtain 15 is located in the box body and is a structure connected end to end with its lower end face open. The fireproof rolling curtain is placed on the movable baffle and its upper end is fixed to the top of the box body. Before the fireproof rolling curtain box 14 is started, the lower end of the fireproof rolling curtain is placed on the movable baffle.

[0077] When the cylinder contracts, the movable baffle changes from a horizontal state to a vertical state, and the fire-proof roller curtain falls to isolate the flame.

[0078] like Figures 8(a) to 8(c) , Fig.13As shown, after the fireproof roller shutter 15 is released by the release switch 19, it can completely cover the parking space below from the front, back, left and right sides to form a relatively isolated space, which can play a certain role in isolating the open flame generated by the vehicle on fire in the parking space as well as the flame heat radiation and heat convection.

[0079] Fig.10 The present invention provides a new energy vehicle immersion fire extinguishing parking space pad and a new energy vehicle parking space fire insulation and heat insulation fire fighting device. In this embodiment, the parking space pad 1 is placed on the original new energy vehicle charging space; the fire fighting device is placed under the original parking space ceiling;

[0080] like Fig. 9 As shown, the new energy vehicle is parked on the parking space pad 1 for storage or charging through the charging pile 16;

[0081] like Fig.10 As shown, when the new energy vehicle battery pack shows signs of thermal runaway (failure, smoke or fire), personnel are manually determined to evacuate, and it is confirmed that the battery is completely out of control. The parking space pad 1 is activated through the inflation switch 18, and the fire extinguishing pool 3 is opened, so that the fire extinguishing pool 3 rises and liquid is injected to cover the above-mentioned new energy vehicle battery pack, so as to extinguish the open fire, reduce the temperature of the battery pack, and perform immersion fire extinguishing to absorb the battery jet fire or explosion impact.

[0082] When the immersion fire extinguishing effect is not good, the fire-fighting device is manually activated by releasing the switch 19 to lower the fire-proof roller curtain 15, forming a partition in front, behind, left and right of the vehicle on fire. This prevents the fire from spreading to the charging pile 16 and other adjacent vehicles or equipment, further reducing the fire loss. This can inhibit the spread of the fire, control the fire range, ensure the safety of surrounding equipment and reduce losses.

[0083] It should be noted that the structure and size of the fire extinguishing pool 3 are only an embodiment. The present invention does not limit the structure and size of the immersion fire extinguishing pool. Any immersion fire extinguishing pool that can be folded, raised, and immersed for fire extinguishing is within the protection scope of the present invention.

[0084] It should be noted that the pneumatic lifting of the parking space pad is only an embodiment, and the present invention does not limit the lifting power source of the immersion fire extinguishing water pool 3. Any lifting driving method of the immersion fire extinguishing water pool that can realize the lifting from folding to lifting is within the protection scope of the present invention.

[0085] It should be noted that installing a parking space pad on a new energy vehicle charging space is only one embodiment, and the specific location and method of installing the parking space pad for a new energy vehicle immersion fire extinguishing device of the present invention are not limited. Any installation location and method of deploying a fire-isolating and heat-insulating fire-fighting device for a new energy vehicle parking space are within the protection scope of the present invention.

[0086] It should be noted that the installation of the fire-fighting device on the parking space ceiling is only one embodiment, and the specific location and specific method of installing the fire-fighting device of the present invention are not limited. Any installation location and installation method of the fire-fighting device in the parking space of a new energy vehicle is within the protection scope of the present invention.

[0087] The parking pad provided by the present invention can be installed on the original new energy charging parking space without civil engineering modification of the original parking space, and can be used to immerse the faulty new energy vehicle for fire extinguishing, fully suppressing and extinguishing the fire in the battery pack of the new energy vehicle. In addition, the immersion fire extinguishing liquid and the water pool can absorb the impact of the thermal runaway explosion of the single battery in the vehicle battery pack to protect the safety of the surrounding personnel and property; the wastewater accumulated in the water pool after the immersion fire extinguishing can be collected and treated in a centralized manner before being discharged to avoid the pollution of the environment by harmful substances in the battery to protect the environment. It solves the problem that traditional fire fighting measures cannot extinguish fires in new energy vehicles and increases the safety of new energy vehicles.

[0088] The fire-fighting device provided by the present invention, in conjunction with the parking space pad in the present invention, can add a protective measure on the basis of immersion fire extinguishing. When the fire of the new energy vehicle cannot be controlled, the fire-insulating and heat-insulating fire-fighting device can form a barrier around the burning vehicle to isolate the open flame and the heat of the flame from being transmitted to adjacent vehicles or related personnel and equipment. Avoid the spread of the fire, reduce the fire hazard, and reduce the disaster loss.

[0089] Example 2

[0090] Based on Example 1, the application scenario is changed.

[0091] like Fig.11 As shown, the malfunctioning new energy vehicle is parked above the train parking pad 1 on the road rescue vehicle 20 .

[0092] When a faulty new energy vehicle is being rescued on the road, if its battery pack suffers from thermal runaway, the parking space pad 1 can be manually started to open the fire extinguishing pool 3, so that the fire extinguishing pool 3 rises and is connected to a fire hydrant or a fire truck to inject liquid to cover the battery pack of the new energy vehicle, extinguish the open fire, lower the temperature of the battery pack, perform immersion fire extinguishing, and absorb the battery jet fire or explosion impact; at the same time, prevent the fire from spreading to the road rescue vehicle, and ensure the safety of life and property of the rescue personnel.

[0093] It should be noted that the installation of the new energy vehicle submersible fire extinguishing parking pad on the road rescue vehicle 20 is only an embodiment, and the specific location and method of installing the new energy vehicle submersible fire extinguishing parking pad of the present invention are not limited. Any installation location and method of the fire-isolating and heat-insulating fire-fighting device that can be deployed in the parking space of a new energy vehicle are within the protection scope of the present invention.

[0094] It should be noted that the installation of the parking space pad on the road rescue vehicle 20 is only an embodiment. The road rescue vehicle on which the parking space pad of the present invention is deployed is not limited. Any implementation method of the road rescue vehicle that can deploy the fire isolation and heat insulation fire-fighting device of the new energy vehicle parking space is within the protection scope of the present invention.

[0095] The parking space pad provided by the present invention can be applied to existing road rescue vehicles and installed on the existing road rescue vehicle trailer board, and can be used to immerse and extinguish the fire of the new energy vehicle battery pack that has failed, so as to fully suppress and extinguish the fire in the new energy vehicle battery pack. In addition, the immersion fire extinguishing liquid and water pool can absorb the impact of the thermal runaway explosion of the single battery in the vehicle battery pack to protect the safety of rescue personnel and surrounding facilities and property. It solves the problem that a new energy vehicle catches fire during the road rescue process and traditional fire fighting measures cannot extinguish the fire, causing the fire to spread to the road rescue vehicle, thereby increasing the safety of new energy vehicles.

[0096] Example 3

[0097] Based on Example 1, the application scenario is changed.

[0098] like Fig.12 As shown, parking pads and firefighting equipment are on board a car ro-ro ship.

[0099] The parking space pad 1 is installed on the deck 23 where the parking space of the car ro-ro ship is located, and the fire-fighting device is installed on the lower surface of the deck 22 above the parking space of the car ro-ro ship.

[0100] like Fig.12 As shown, the transported new energy vehicles are parked on parking space pads 1 respectively.

[0101] During the transportation of a faulty new energy vehicle on a roll-on / roll-off ship, if the battery pack of the faulty new energy vehicle suffers from thermal runaway, the parking pad 1 can be manually started to open the fire extinguishing pool 3, so that the immersion fire extinguishing pool 3 rises and water from the water body around the ship is pumped into the fire extinguishing pool 3 to cover the battery pack of the new energy vehicle, so as to extinguish the open fire, reduce the temperature of the battery pack, perform immersion fire extinguishing, and absorb the battery jet fire or explosion impact.

[0102] At the same time, the fire-fighting device can be manually activated to lower the fire-proof roller curtain 15 to form a partition in front, behind, left and right of the burning vehicle, thereby blocking the fire from spreading in the cabin and affecting other adjacent vehicles or equipment, further reducing the fire loss, thereby suppressing the spread of the fire, controlling the fire range, ensuring the safety of surrounding equipment and reducing losses.

[0103] It should be noted that the installation of the parking space pad on the deck 23 where the parking space of the car roll-on / roll-off ship is located is only an embodiment, and the specific location and method of installing the new energy vehicle immersion fire extinguishing parking space pad of the present invention are not limited. Any installation location and method of the fire-proof and heat-insulating fire-fighting device that can be deployed in the new energy vehicle parking space are within the protection scope of the present invention.

[0104] It should be noted that the installation of the fire-fighting device on the lower surface of the deck 22 above the parking space of the car roll-on / roll-off ship is only an embodiment, and the specific location and method of installing the fire-proof and heat-insulating fire-fighting device in the parking space of new energy vehicles of the present invention are not limited. Any installation location and method of deploying the fire-proof and heat-insulating fire-fighting device in the parking space of new energy vehicles are within the protection scope of the present invention.

[0105] It should be noted that the installation of the parking space pad on the car roll-on / roll-off ship 21 is only an embodiment. The present invention does not limit the car roll-on / roll-off ship 21 on which the parking space pad is deployed, and any implementation method of the car roll-on / roll-off ship that can deploy fire-fighting equipment is within the protection scope of the present invention.

[0106] The parking pad provided by the present invention can be installed on the original parking space without rebuilding the original parking space of the car roll-on / roll-off ship, and can immerse the faulty new energy vehicle to extinguish the fire, fully suppressing and extinguishing the fire of the new energy vehicle battery pack. In addition, the immersion fire extinguishing liquid and water pool can absorb the impact of the thermal runaway explosion of the single battery in the vehicle battery pack to protect the safety of the hull, adjacent vehicles and personnel; reduce the fire safety hazards of new energy vehicles transported by car roll-on / roll-off ships, and increase the safety guarantee of new energy vehicle transportation.

[0107] The fire-fighting device provided by the present invention, in conjunction with the submerged fire-fighting stand pad for new energy vehicles in the present invention, can add a protective measure on the basis of submerged fire-fighting. When the fire of the new energy vehicle cannot be controlled, the fire-insulating and heat-insulating fire-fighting device can form a barrier around the burning vehicle to isolate the open flame and the heat of the flame from being transferred to adjacent parked vehicles or related personnel and equipment. This prevents the fire from spreading inside the cabin and causing the entire ship to catch fire, reduces fire hazards, and reduces disaster losses.

[0108] The above are only preferred embodiments of the present invention and do not limit the present invention in any way.
