Description

Technical Field

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

[0002] In related technologies, in scenarios such as vehicle and object parking and storage, 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 danger. In view of the thermal runaway mechanism of automotive 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 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 the actual fire extinguishing effect is also poor. Most new energy vehicles are basically completely burned after catching fire, and the fire extinguishing effect is poor. Summary of the Invention

[0035] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, and they can be communicated inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Next, with reference to Figures 1-5 the drawings, a vehicle fire extinguishing device 100 according to an embodiment of the present invention will be described.

[0038] As Figure 1 and Figure 2 shown, a vehicle fire extinguishing device 100 according to an embodiment of the present invention includes: an isolation chamber 10, a lifting mechanism 20, and a fire extinguishing pool 30. The bottom of the isolation chamber 10 is open, the isolation chamber 10 has a first direction, both ends of the isolation chamber 10 in the first direction are open, and the first direction is perpendicular to the height direction of the isolation chamber 10; the lifting mechanism 20 is arranged in the isolation chamber 10 and is used to lift the vehicle 200 to be extinguished; the fire extinguishing pool 30 can be moved into or out of the isolation chamber 10 along the first direction.

[0039] "The isolation chamber 10 has a first direction", referring toFigure 2 The left - right direction. The first direction can refer to the length direction of the isolation chamber 10 or the width direction of the isolation chamber 10. It can be understood that the isolation chamber 10 is a semi - open structure, with the bottom and opposite ends both open, and the other opposite ends can play a blocking role. When the vehicle 200 is located inside the isolation chamber 10, the two ends of the vehicle 200 can be isolated from the outside. For example, referring to Figure 2 and Figure 3 , the front and rear ends and the bottom of the isolation chamber 10 are open, but the left and right sides are not open. When the vehicle 200 is inside the isolation chamber 10, the isolation chamber 10 can isolate the left and right sides of the vehicle 200 from the external environment.

[0040] A fire - proof and heat - insulating layer can be provided inside the isolation chamber 10. The fire - proof and heat - insulating layer can be refractory materials such as high - alumina, silicon carbide, and magnesia. The fire - proof and heat - insulating layer can block the flames and high temperatures generated by the burning of the vehicle 200, preventing rescue personnel outside the isolation chamber 10 from being burned by the high temperature. At the same time, the fire - proof and heat - insulating layer has good high - temperature resistance performance, can maintain its own structural stability in a long - term fire and high - temperature environment, will not deform, melt or fall off due to high temperature, helps to maintain the overall structural strength of the isolation chamber 10, prevents the isolation chamber 10 from deforming due to heat and affecting the sealing performance and fire - extinguishing effect, ensures that the vehicle fire - extinguishing device 100 continuously and stably plays a role during the duration of the fire, and thus improves the reliability of the vehicle fire - extinguishing device 100.

[0041] The lifting mechanism 20 can refer to a mechanical device for lifting the burning vehicle 200. It can be, but is not limited to, a hydraulic lifting mechanism, an electric lifting mechanism, a screw lifting mechanism, a pneumatic lifting mechanism, a hoisting device, etc. The lifting mechanism 20 can lift the wheels of the vehicle 200 or other positions at the bottom of the vehicle 200. For example, the lifting mechanism 20 can quickly hold the four wheels of the vehicle 200 to realize the lifting and lowering of the vehicle 200.

[0042] The fire - extinguishing pool 30 can refer to a structural member similar to a pool. The fire - extinguishing pool 30 can be moved into or out of the isolation chamber 10 in the first direction. Among them, the fire - extinguishing medium in the fire - extinguishing pool 30 can be, but is not limited to, liquid, gas, powder, etc. For example, the fire - extinguishing medium can be water.

[0043] When the vehicle 200 catches fire spontaneously, during the process of extinguishing the fire on the vehicle 200, the isolation chamber 10 can move along the first direction under the action of an external force to accommodate the vehicle 200, so as to cover the burning vehicle 200. Then, the lifting mechanism 20 can lift the bottom of the vehicle 200, which can be the wheels of the vehicle 200 or other positions at the bottom of the vehicle 200. After the vehicle 200 is lifted to a certain height, the fire extinguishing pool 30 starts to enter the isolation chamber 10 along the first direction. After the fire extinguishing pool 30 completely enters the isolation chamber 10, the lifting mechanism 20 lowers the vehicle 200 into the fire extinguishing pool 30. The fire extinguishing medium can be pre-introduced into the fire extinguishing pool 30, or the fire extinguishing medium can be added after the vehicle 200 enters, so that the battery pack encapsulated at the bottom of the vehicle 200 is completely immersed in the fire extinguishing medium, enabling 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.

[0044] For example, the fire extinguishing medium can be fire-fighting water, and the battery pack at the bottom of the vehicle 200 can be completely immersed in the fire-fighting water at a certain height, which can improve the fire extinguishing effect and reduce the water consumption. Among them, the movement of the isolation chamber 10 and the fire extinguishing pool 30 can be achieved by towing or pushing with an external auxiliary vehicle, or the isolation chamber 10 and the fire extinguishing pool 30 can have their own power, which is not specifically limited here.

[0045] Since the isolation chamber 10 can isolate the burning vehicle 200 from the outside world in the first space and extinguish the fire inside the isolation chamber 10, and the vehicle 200 is placed in the fire extinguishing pool 30. During the fire extinguishing process, the fire extinguishing pool 30 can prevent the high temperature, hot air flow or flame formed by the fire at the bottom of the vehicle 200 from overflowing or shooting out. At the same time, the left and right side walls of the isolation chamber 10 (see Figure 1 ) can also play a role in blocking the high temperature, hot air flow or flame. That is to say, the cooperation of the isolation chamber 10 and the fire extinguishing pool 30 can prevent the high temperature, hot air flow or flame generated when the vehicle 200 burns from overflowing or shooting out from the bottom of the vehicle 200, thereby avoiding damage to the rescue personnel and reducing the potential safety hazards of the rescue.

[0046] In the above technical solution, the isolation chamber 10 can also quickly isolate the self - igniting vehicle 200, which is conducive to achieving rapid rescue and extinguishing fires. This can ensure the timeliness of fire extinguishing, reduce the fire - extinguishing time, and avoid the complete burning of the vehicle 200, so as to protect the vehicle 200 as much as possible and reduce property losses. Since the battery pack contains chemical substances, toxic and harmful gases will be produced during combustion, and other components of the vehicle 200 will also produce toxic and harmful gases when burning. By using the isolation chamber 10 to enclose and submerging the bottom of the vehicle 200 through the fire - extinguishing pool 30 for fire extinguishing, most of the toxic and harmful gases can be retained in the fire - extinguishing pool 30. For example, when the fire - extinguishing medium is water, the toxic and harmful gases can dissolve in the fire - fighting water, thus preventing the toxic and harmful gases from spreading to the surrounding area and ensuring the safety of rescue personnel and the surrounding people.

[0047] On the other hand, when the vehicle fire - extinguishing device 100 extinguishes the fire of the vehicle 200, since the fire - extinguishing medium will form contaminated waste after contacting the battery pack, taking water as an example of the fire - extinguishing medium, the fire - fighting water after fire extinguishing will be harmful. During the entire fire - extinguishing process, the fire - extinguishing medium remains in the fire - extinguishing pool 30, which can also prevent the fire - extinguishing medium from spreading to the surrounding environment and causing pollution to the objects, people or underground water resources in the surrounding environment. Among them, the fire - extinguishing pool 30 can be transported to the treatment plant for treatment after the fire extinguishing, which is conducive to meeting the requirements of cleanliness and environmental protection. For example, when the fire - extinguishing medium is water, the wastewater in the fire - extinguishing pool 30 can be transported to the wastewater treatment plant for recycling and treatment.

[0048] According to the vehicle fire - extinguishing device 100 of the embodiment of the present invention, by pushing the isolation chamber 10 to cover the vehicle 200, the vehicle 200 on fire can be isolated from the external environment, preventing the fire from spreading to the surrounding environment and protecting the safety of surrounding facilities and personnel. The lifting mechanism 20 can perform lifting operations on the vehicle 200 according to the fire - extinguishing requirements, so that the vehicle 200 can be submerged in the fire - extinguishing medium in the fire - extinguishing pool 30 for fire extinguishing, which can improve the fire - extinguishing effect, improve the fire - extinguishing efficiency, reduce the consumption of the fire - extinguishing medium, save costs, and since the fire - extinguishing medium is located in the fire - extinguishing pool 30, it can avoid secondary pollution of the surrounding environment by the fire - extinguishing medium, improve the environmental protection of fire extinguishing, and prevent the high temperature, hot air flow or flame of the vehicle 200 from causing injury to rescue personnel, thus improving the safety of rescue.

[0049] In some embodiments of the present invention, referring to Figure 1 and Figure 2 , the isolation chamber 10 is provided with a first traveling mechanism 101, and the first traveling mechanism 101 is used to drive the isolation chamber 10 to move in the first direction.

[0050] The first traveling mechanism 101 may refer to a device that enables the isolation chamber 10 to move. The first traveling mechanism 101 may be, but is not limited to, a wheeled traveling mechanism, a crawler traveling mechanism, a rail traveling mechanism, traveling wheels, a traveling chassis, etc. The method of using traveling wheels is relatively simple, and the isolation chamber 10 can be manually pushed. Using a traveling chassis can achieve electric traveling or remote control to drive the isolation chamber 10 to travel, with simple operation and easy to achieve automation.

[0051] In the above technical solution, the first traveling mechanism 101 can quickly move the isolation chamber 10 to a specific position near the burning vehicle 200. Compared with manual pushing or mechanical device pushing, the first traveling mechanism 101 can reduce the difficulty of moving the isolation chamber 10. Whether it is manual pushing or mechanical device pushing, it can reduce the operation difficulty. Thus, fire extinguishing can be carried out quickly, thereby preventing the spread of fire and improving the fire extinguishing efficiency.

[0052] In some embodiments of the present invention, referring to Figure 1 and Figure 5 , the fire extinguishing pool 30 is provided with a second traveling mechanism 31, and the second traveling mechanism 31 is used to drive the fire extinguishing pool 30 to move in the first direction. The second traveling mechanism 31 may refer to a device that enables the fire extinguishing pool 30 to move. The second traveling mechanism 31 may be, but is not limited to, traveling wheels, a traveling chassis, etc. The method of using traveling wheels is relatively simple, and the fire extinguishing pool 30 can be manually pushed. Using a traveling chassis can achieve electric traveling or remote control to drive the fire extinguishing pool 30 to travel, with simple operation and easy to achieve automation.

[0053] In the above technical solution, the second traveling mechanism 31 can make it easier for the fire extinguishing pool 30 to move into or out of the isolation chamber 10, and can reduce the operation difficulty of the fire extinguishing pool 30.

[0054] In some embodiments of the present invention, referring to Figure 5 , the isolation chamber 10 includes at least two split parts 11, and the at least two split parts 11 are spliced and connected along the first direction. Each split part 11 includes a connected main body part 111 and a telescopic part 112, and the telescopic part 112 can telescopically move along the first direction relative to the main body part 111.

[0055] The isolation chamber 10 includes at least two split parts 11. For example, the number of split parts 11 can be two, three, four, five, six, etc. The split parts 11 are spliced and connected along the first direction, and the connection method can be, but is not limited to, bolts, mortise and tenon, clamps, welding, etc.

[0056] In the above technical solution, since each split part 11 includes a connected main body part 111 and a telescopic part 112 that can be telescoped in the first direction, when it is necessary to accommodate vehicles 200 with different wheelbases, the length of the isolation chamber 10 in the first direction can be flexibly adjusted by the telescoping of the telescopic part 112. For a vehicle 200 with a smaller wheelbase, the telescopic part 112 can be appropriately contracted to reduce the space of the isolation chamber 10, so that the amount of extinguishing medium used can be reduced during fire extinguishing, and the fire extinguishing efficiency can be improved. For a vehicle 200 with a larger wheelbase, the telescopic part 112 can be extended to increase the space of the isolation chamber 10, ensuring that the vehicle 200 can fully enter the isolation chamber 10 for fire extinguishing operations, and improving the coverage and effect of fire extinguishing.

[0057] In some embodiments of the present invention, referring to Figure 1 , the lifting mechanism 20 includes at least two lifting components 21. The number of lifting components 21 is equal to and corresponds one-to-one with the number of split parts 11, and the lifting components 21 are provided on the main body part 111 of the corresponding split part 11. For example, referring to Figure 1 , the lifting mechanism 20 has two lifting components 21 and the split part 11 has two.

[0058] In the above technical solution, each split part 11 corresponds to one lifting component 21, so that the vehicle 200 can be evenly and stably supported during the lifting process. At the same time, when extinguishing a fire on a vehicle 200 with an overly long wheelbase, the weight of the vehicle 200 is too large, and the number of split parts 11 used increases, and then the number of lifting components 21 increases, so that the vehicle 200 with an overly large weight can be lifted to ensure that the fire extinguishing operation can be stably carried out, and the reliability of the vehicle fire extinguishing device 100 is improved. Among them, at least part of the two lifting components 21 can enter the interior of the fire pool 30 together with the vehicle 200.

[0059] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the lifting component 21 includes two lifting parts 211. The two lifting parts 211 are provided at both ends of the split part 11 in the second direction. The second direction is perpendicular to the first direction and parallel to the ground.

[0060] The second direction can refer to the left-right direction in Figures 1 to 3 . In the above technical solution, each lifting part 211 can respectively support and lift one side of the vehicle 200 in the second direction, so that the two lifting parts 211 can lift simultaneously on the left and right sides of the vehicle 200. By adopting the scheme in which the lifting component 21 is composed of two lifting parts 211, the structure of the lifting component 21 can be simplified, and the layout difficulty of the lifting component 21 can be reduced.

[0061] Optionally, the movable end of the lifting component 211 can be constructed as an L-shaped and forked lifting plate, thereby making it easier to pull out the wheels of the vehicle 200, thereby improving the stability and reliability of the vehicle 200 during the lifting process.

[0062] In some embodiments of the present invention, the main body portion 111 and the telescopic portion 112 are both in the shape of a door arch; or, referring to Figure 5 The main body part 111 is in the shape of a door arch, the telescopic part 112 is in the shape of a plate, and is arranged at both ends of the second direction of the main body part 111, and the second direction is perpendicular to the first direction and the height direction of the isolation chamber 10.

[0063] The “first direction” can refer to Figure 5 The front and rear direction of the “second direction” can refer to Figure 1 left and right direction.

[0064] When the main body 111 and the telescopic part 112 are both in the shape of a gate arch, the gate arch structure has good mechanical properties and can evenly distribute the pressure from above to both sides. Compared with other shapes, it is less likely to deform when subjected to greater pressure. Whether it is the vertical pressure generated during the lifting process of the vehicle 200 or the impact force that may be received during fire extinguishing, the main body 111 and the telescopic part 112 in the shape of a gate arch can better withstand it, ensuring the overall structural stability of the isolation chamber 10.

[0065] The main part 111 is in the shape of a gate arch, and the telescopic part 112 is in the shape of a plate. When the main part 111 is arranged at both ends of the second direction of the main part 111, the main part 111 adopts a gate arch, which retains the advantages of the gate arch structure in terms of structural stability, space utilization and airflow organization. The telescopic part 112 adopts a plate-like structure, which can reduce the amount of material used compared to the main part 111 and the telescopic part 112 are both in the shape of a gate arch, thereby reducing the manufacturing cost. Under the premise of ensuring the function of the isolation chamber 10, the material cost is reasonably reduced and the economy of the product is improved. At the same time, the lighter telescopic part 112 also helps to reduce the weight of the entire isolation chamber 10, and the requirements for its supporting structure and foundation are also reduced accordingly.

[0066] In some embodiments of the present invention, reference Figure 1 and Figure 3, the vehicle fire extinguishing device 100 includes a partition member 40. The partition member 40 is provided at both ends of the isolation chamber 10 in the second direction and extends along the first direction. The second direction is perpendicular to the first direction and the height direction of the isolation chamber 10. In the above technical solution, the partition member 40 can hermetically isolate the bottom of both ends of the isolation chamber 10 in the second direction and extending along the first direction from the ground, so as to prevent the high temperature, hot air flow or flame caused by the combustion of the vehicle 200 from leaking out from the bottom of both ends of the isolation chamber 10 in the second direction and extending along the first direction, and further prevent the hot air flow or flame from causing damage to the rescue personnel. It can be seen that the use of the vehicle fire extinguishing device 100 can improve the rescue safety while achieving efficient fire extinguishing. Refer to Figure 1 and Figure 3 , the partition member 40 can prevent the high temperature, hot air flow or flame caused by the combustion of the vehicle 200 from leaking out from the bottom of the left and right side walls of the isolation chamber 10, which is beneficial to ensuring the safety of the rescue personnel.

[0067] In some embodiments of the present invention, the partition member 40 has a first state and a second state. When the partition member 40 is in the first state, it does not contact the ground. When the partition member 40 is in the second state, it contacts the ground.

[0068] In the above technical solution, the partition member 40 can switch between the first state and the second state, so that the state of the partition member 40 can be flexibly controlled. When the partition member 40 does not contact the ground in the first state, the friction between the isolation chamber 10 and the ground can be reduced when the isolation chamber 10 moves, and the isolation chamber 10 can be moved more easily. Moreover, it can prevent the partition member 40 from being damaged due to frictional dragging with the ground. When the partition member 40 contacts the ground in the second state, the partition member 40 can play a sealing and isolating role, and can seal and isolate the bottom of the isolation chamber 10 from the ground.

[0069] In some embodiments of the present invention, the partition member 40 is movable along the height direction of the isolation chamber 10. A cavity is formed inside the partition member 40, and the partition member 40 is provided with a filler inlet communicating with the cavity. The filler inlet is used for injecting a filler to enable the partition member 40 to switch from the first state to the second state.

[0070] When no filler is placed in the cavity of the partition member 40, the overall weight of the partition member 40 is relatively light and it does not contact the ground. When the filler is placed in the cavity of the partition member 40 through the filler inlet, the partition member 40 can contact the ground under the action of gravity to achieve a sealing effect (see Figure 1 ). The partition member 40 can be, but is not limited to, a rubber material member, a woven bag or a leather bag, etc. When the partition member 40 is a rubber material member or a leather bag, the filler can be, but is not limited to, water, flame retardant liquid, gravel, sand and stone, etc.; when the partition member 40 is a woven bag, the filler can be, but is not limited to, gravel, yellow sand or soil, etc.

[0071] In the above technical solution, the insulating member 40 is moved up and down by placing fillers, so that the insulating member 40 can be switched between the first state and the second state. This method is simpler, more reliable, easy to reuse, and less difficult to operate.

[0072] In some embodiments of the present invention, reference Figure 1 The insulating member 40 is a water bag with elastic contraction function. In this technical solution, the water bag can be filled with fire water, so that the water bag can form a water-retaining and heat-insulating cofferdam around the isolation chamber 10, which has good sealing and fire-resistant effects. In addition, water is easy to use as a filling material, the water bag has a simple structure, and the cost is relatively low, which can save costs.

[0073] In some embodiments of the present invention, reference Figure 1 and Figure 2 The vehicle fire extinguishing device 100 includes a spray mechanism 50 and a direct spray mechanism 60. The spray mechanism 50 and the direct spray mechanism 60 are arranged on the isolation compartment 10. The spray mechanism 50 and the direct spray mechanism 60 are configured to provide their own fire extinguishing medium or introduce fire extinguishing medium from the outside.

[0074] The spray mechanism 50 may refer to a mechanism capable of spraying a fire extinguishing medium, such as a spray pipe, a spray nozzle, etc. The spray mechanism 50 may be disposed on the top, side, or both of the isolation chamber 10, so that the fire extinguishing medium can be evenly sprayed on the surface of the burning vehicle 200 and the surrounding space in a spraying manner, forming a large area of ​​water mist or foam covering layer, which can reduce the surface temperature of the vehicle 200 and prevent the fire from spreading to other parts on the one hand, and on the other hand, the sprayed water mist or foam can isolate the air and inhibit the combustion reaction, thereby achieving the purpose of extinguishing and controlling the fire.

[0075] The spray mechanism 50 may be a fire extinguishing mechanism that cooperates with an external device, and the external device may be, but is not limited to, a fire hydrant or a fire truck, etc. The spray mechanism 50 may also refer to a fire extinguishing mechanism that has its own fire extinguishing medium.

[0076] The direct injection mechanism 60 may refer to a mechanism that precisely sprays the fire extinguishing medium onto a specific fire location of the vehicle 200, for example, onto the engine compartment, near the fuel tank, electrical equipment and other key areas of the vehicle 200. The direct injection mechanism 60 may be directly connected to an external fire truck, fire hydrant or other water hose interface, spray water to extinguish the fire through a valve switch, and then through high-pressure injection, the fire extinguishing medium may penetrate the flame, directly act on the root of the fire source, and quickly extinguish the flame. The direct injection mechanism 60 may be a large-diameter pipe that delivers the fire extinguishing medium.

[0077] The direct injection mechanism 60 can be a fire extinguishing mechanism that cooperates with an external device, and the external device can be, but is not limited to, a fire hydrant or a fire truck, etc. The direct injection mechanism 60 can also refer to a fire extinguishing mechanism with its own fire extinguishing medium.

[0078] In the above technical solution, the combination of the sprinkler mechanism 50 and the direct injection mechanism 60 cooperate with each other, and an appropriate fire extinguishing method can be selected according to the specific situation of the burning of the vehicle 200. Or, by using the sprinkler mechanism 50 and the direct injection mechanism 60 simultaneously, the burning vehicle 200 can be extinguished more quickly and effectively, improving the fire extinguishing efficiency.

[0079] In some embodiments of the present invention, referring to Figure 2 and Figure 3 , the sprinkler mechanism 50 includes a plurality of sprinkler parts 51. The plurality of sprinkler parts 51 are arranged at intervals in the first direction and extend in the second direction. The plurality of sprinkler parts 51 are sequentially connected. Each sprinkler part 51 is provided with a plurality of sprinkler heads 511. The plurality of sprinkler heads 511 are arranged at intervals in the second direction. Among them, the sprinkler part 51 can be, but is not limited to, a sprinkler pipe, etc.

[0080] In the above technical solution, by including a plurality of sprinkler parts 51 in the sprinkler mechanism 50, and each sprinkler part 51 is provided with a plurality of sprinkler heads 511, this solution can increase the sprinkling coverage area of the sprinkler mechanism 50, thereby improving the fire extinguishing effect on the vehicle 200 and increasing the fire extinguishing efficiency.

[0081] In some embodiments of the present invention, referring to Figure 4 , the fire pool 30 includes a pool body 32 and a door panel 33. One end of the pool body 32 in the first direction is provided with an opening 32a. The door panel 33 is movably arranged on the pool body 32 to open or close the opening 32a.

[0082] In the above technical solution, referring to Figure 4 , Figure 4 is a schematic diagram of the door panel 33 in the open state. When the door panel 33 is opened, the opening 32a of the pool body 32 can first enter the isolation chamber 10. Therefore, the lifting mechanism 20 only needs to lift the vehicle 200 by a small height, which can reduce the lifting stroke requirement for the lifting mechanism 20 and reduce the cost of the lifting mechanism 20. Moreover, since the vehicle 200 does not need to be lifted to a high height, the above solution can also reduce the height requirement for the isolation chamber 10, which is beneficial to reducing the size of the isolation chamber 10, saving the materials used for the isolation chamber 10, and is beneficial to operating in a space with a lower floor height. For example, for extinguishing fires in indoor spaces such as basements. Using the above solution can also reduce the weight of the isolation chamber 10 and facilitate the movement of the isolation chamber 10. When the door panel 33 is closed, fire extinguishing operations are carried out on the vehicle 200. Fire extinguishing medium is injected into the fire pool 30 through an external fire extinguishing medium conveying device. The fire extinguishing medium can have a certain height in the fire pool 30 for immersion fire extinguishing, improving the reliability of fire extinguishing.

[0083] Exemplarily, the external fire extinguishing medium delivery device may be a fire hose or a fire truck.

[0084] In the above technical solution, after the fire extinguishing is completed, the wastewater in the fire extinguishing pool 30 can be carried to a sewage treatment plant for treatment, and the pollutants therein can be effectively removed, and then discharged after reaching the discharge standard, thereby reducing environmental pollution.

[0085] In some embodiments of the present invention, the fire extinguishing pool 30 is provided with an inlet and an outlet. The inlet can be used to introduce the fire extinguishing medium, and the outlet can be used to discharge the fire extinguishing medium. Especially after the fire extinguishing of the vehicle 200 is completed, the fire extinguishing pool 30 can be removed from the isolation chamber 10 by means of a dragging mechanism, a tractor or manually, and then the fire extinguishing medium in the fire extinguishing pool 30 can be discharged through the outlet, and the fire extinguishing medium can be centrally processed, such as recycling or purifying and discharging the fire extinguishing medium.

[0086] In some embodiments of the present invention, referring to Figure 4 and Figure 5 , the fire extinguishing pool 30 is provided with a liquid level detection and alarm mechanism 34 and a leakage detection and alarm mechanism 35. The liquid level detection and alarm mechanism 34 is configured to alarm when the height of the fire extinguishing medium in the fire extinguishing pool 30 is less than a preset value, and the leakage detection and alarm mechanism 35 is configured to alarm when a leakage situation is detected in the fire extinguishing pool 30.

[0087] In the above technical solution, the liquid level detection and alarm mechanism 34 can continuously monitor the height of the fire extinguishing medium in the fire extinguishing pool 30, and alarm when the medium height is less than the preset value, reminding the operator to replenish the fire extinguishing medium in time. This ensures that the fire extinguishing pool 30 always has sufficient fire extinguishing medium reserve during a fire, maintaining the fire extinguishing ability of the fire extinguishing device, avoiding the inability to effectively carry out the fire extinguishing work due to insufficient fire extinguishing medium, thereby improving the fire extinguishing success rate and ensuring the safety of personnel and equipment. The leakage detection and alarm mechanism 35 can promptly detect the leakage situation in the fire extinguishing pool 30 and alarm. During the fire extinguishing process, especially when using water or other conductive fire extinguishing media, leakage may cause dangers such as electrocuting the operator and affecting the normal operation of the fire extinguishing equipment. By promptly alarming, the operator can quickly take measures to cut off the power supply or eliminate the leakage fault, avoiding secondary disasters caused by leakage, reducing the risk at the fire scene, and ensuring the safe progress of the fire extinguishing work. The combined action of these two detection and alarm mechanisms can continuously monitor the working state of the fire extinguishing pool 30, promptly detect potential problems and alarm, and improve the reliability of the fire extinguishing pool 30.

[0088] In some embodiments of the present invention, a temperature monitoring device and a toxic gas monitoring device are provided in the isolation chamber 10. The temperature monitoring device can monitor the temperature change in the isolation chamber 10 in real time, can detect abnormal fluctuations in temperature in a timely manner, and adopt corresponding fire extinguishing operations to improve the fire extinguishing efficiency. The toxic gas monitoring device can detect the presence and concentration change of toxic gases in a timely manner. Once the concentration exceeds the safety standard, an alarm will be issued to remind personnel to evacuate as soon as possible or take protective measures to avoid the occurrence of personnel poisoning accidents and ensure the safety of personnel's lives.
