Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle fire treatment, and particularly to an immersion treatment device and an immersion treatment method for electric vehicle fires. Background Art

[0002] An electric vehicle is a vehicle mainly driven by electricity, whose power source is an on-vehicle power battery. Electrical energy is converted into mechanical energy through an electric motor to drive the vehicle to run. However, the fire safety problem of electric vehicles has become increasingly prominent, posing a great threat to people's lives and property safety.

[0003] Currently, for thermal runaway fires of electric vehicle power batteries, traditional fire extinguishing methods often fail to effectively extinguish the fire, and the power batteries of electric vehicles are prone to reignite. Since the structure of electric vehicle power batteries is complex and located at the bottom of the chassis, the released fire extinguishing agent may not be able to effectively reach the root of the fire source, resulting in incomplete fire extinguishing and easy reignition. Moreover, affected by the limited spraying distance and coverage range, for large-scale fires, it is difficult to control the fire in a short time and cut off the fire propagation path in time; for example, the water sprayed by the automatic sprinkler systems installed in some places can only cover the top or side of the electric vehicle, and it is difficult to directly cover and cool the power battery box at the bottom of the chassis, the source of the fire, resulting in the continuous spread of electric vehicle fires.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information constitutes prior art known to those of ordinary skill in the art.

[0017] The present invention also claims to protect an electric vehicle fire immersion treatment method, which applies an electric vehicle fire immersion treatment device, including:

[0018] A base is embedded in the docking area;

[0019] At least three second enclosures are arranged in the base to ensure that two adjacent second enclosures are plugged and matched with each other;

[0020] A first enclosure is arranged at the docking area above the outer edge of the base;

[0021] When a fire accident occurs to the parked object, the driving mechanism is activated to drive the second enclosure to move to be plugged and matched with the first enclosure, and the first enclosure, the second enclosure and the docking area enclose a space;

[0022] The liquid injection mechanism is started to inject fluid into the space to immerse the parked object;

[0023] The monitoring mechanism performs the operation of monitoring the leakage of the fluid in the space.

[0024] The advantages of the present invention are as follows:

[0025] First of all, the present invention embeds a base in the docking area and sets a first enclosure at the docking area above the outer edge of the base. Not only can the first enclosure play a role in marking the docking area, but when the docked object does not spontaneously combust, the base is embedded in the docking area and will not cause any obstruction to the entry and exit of the docked object from the docking area. Secondly, in cooperation with the driving mechanism to drive the second enclosure, the second enclosure is raised to be flush with the first enclosure, so that the first enclosure, the second enclosure and the docking area jointly enclose a space. Moreover, since the adjacent two second enclosures are in plug-in fit with each other, and the adjacent surfaces of the second enclosure and the first enclosure are in plug-in fit with each other, it can be obtained that the formed space has high airtightness and can be used for storing fluids in a closed manner. Finally, by injecting fluid into the space through the liquid injection mechanism, the spontaneous combustion part of the docked object is immersed in the fluid. The whole process not only has a large coverage range and can immerse all parts of the docked object where spontaneous combustion occurs, eliminating the fire at the spontaneous combustion part and covering the components of the docked object in thermal runaway to prevent re-ignition. In addition, due to the enclosure effect and fluid storage effect of the space, the fire spread path is effectively blocked, avoiding the fire problem of other docked objects, achieving multiple benefits at one stroke. On this basis, a monitoring mechanism is specially used in cooperation. By monitoring the leakage of the fluid in the space, early warning is given, achieving a good safety prompt effect.

[0026] Secondly, the base is in the structure of a U-shaped frame with a hollow interior, and a first enclosure is set at the docking area above the U-shaped opening of the base. In this way, when the second enclosure sliding in the base slides, it will not interfere with the first enclosure, and at the same time, it can ensure that when the second enclosure slides to be flush with the first enclosure, they jointly enclose a sealed space.

[0027] Thirdly, the long side frame is set in the structure of an L-shaped frame, and the side enclosure is in the structure of an L-shaped plate adapted to it. On the one hand, when the side enclosure slides, due to the limitation of the special shape, the problem of deviation during sliding can be avoided; on the other hand, the protruding end of the L-shaped plate and the first sliding grooves recessed on both sides of the first enclosure form a plug-in fit when the L-shaped plate slides. Through the staggered plug-in, instead of the direct alignment method, the airtightness of the connection can be guaranteed.

[0028] Similarly, a plug-in fit is set between the side enclosure and the front enclosure to ensure the airtightness of the connection between the side enclosure and the front enclosure, and finally the airtightness of the overall space can be guaranteed, laying a solid foundation for injecting fluid later.

[0029] It should be noted that once a spontaneous combustion problem of the docked object occurs, the fire is likely to spread rapidly. Therefore, rapid immersion needs to be achieved. Therefore, nozzles are set on the inner walls of both the first enclosure and the side enclosure, so that the water injection speed is significantly increased.

[0030] 6. When the monitoring mechanism is actually used, by setting the first conductive rod which is grounded, and cooperating with the second conductive rod to connect with the fluid, when the fluid in the space leaks electricity, a voltage difference will be generated between the first conductive rod and the second conductive rod. By observing the reading on the monitoring meter, early warning can be carried out to avoid electric shock, which has a safety protection function.

[0031] 7. Moreover, after extinguishing the fire, considering the drainage problem in the space, by opening the valve and starting the second driving unit to extract the fluid in the space, the fluid is emptied. After emptying, by operating the driving mechanism in reverse, an electric vehicle fire immersion treatment device is restored to its original state.

[0032] 8. Considering the complexity of the space placement objects in the docking area, by setting a filter screen at the notch of the liquid discharge tank, the sundries that accidentally enter the space are filtered by the filter screen to avoid the problem of blockage of the third connecting pipe.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0048] Embodiment 1

[0049] Refer to Figures 1 to 5, this embodiment claims to protect an immersion treatment device for electric vehicle fires, which includes a base 1, a first enclosure 2, at least three second enclosures, a driving mechanism, a liquid injection mechanism, a liquid drainage device, and a monitoring mechanism. The base 1 is embedded in the docking area. A first enclosure 2 is provided at the docking area above the outer edge of the base 1, and the first enclosure 2 extends onto the docking area. A slideway is formed along the outer edge inside the base 1, and at least three second enclosures are arranged in the slideway. The base 1 is constructed as a U-shaped frame with a hollow interior, and the top of the hollow cavity is penetrated to form a slideway, in which at least three second enclosures are arranged; a first enclosure 2 is provided at the docking area above the U-shaped opening of the base 1, and adjacent second enclosures are configured to be plugged and matched with each other. The base 1 includes a wide frame 1a and long frames 1b. The long frames 1b are vertically arranged on both sides of the wide frame 1a to form a U-shaped frame structure. The second enclosure arranged inside the wide frame 1a is the front enclosure 7. One end of the side enclosure 6 away from the first enclosure 2 protrudes a second convex block or recesses a second groove, which is plugged and matched with the second grooves or second protrusions recessed on both sides of the side enclosure 6. Similarly, the side enclosure 6 and the front enclosure 7 are plugged and matched to ensure the sealing performance at the connection between the side enclosure 6 and the front enclosure 7. Ultimately, the overall sealing performance of the space can be guaranteed, laying a foundation for injecting fluid later. The long frame 1b is constructed as an L-shaped frame. Above the ends of the two long frames 1b away from the wide frame 1a, both sides of the first enclosure 2 are installed, and the gap between the ends of the two long frames 1b forms the U-shaped opening of the base 1; both sides of the first enclosure 2 are recessed with first chutes 20, and the first chutes 20 extend along the wide side of the first enclosure 2; the second enclosure arranged inside the long frame 1b is the side enclosure 6, and the side enclosure 6 is constructed as an L-shaped plate structure adapted to its shape. Both sides of the side enclosure 6 are plugged and matched with the first chutes 20 along the vertical direction. The long frame 1b is set as an L-shaped frame structure, and the side enclosure 6 is constructed as an L-shaped plate structure adapted to its shape. On the one hand, when the side enclosure 6 slides, through the limitation of the special shape, the problem of deviation during sliding can be avoided; on the other hand, the protruding end of the L-shaped plate and the first chutes 20 recessed on both sides of the first enclosure 2 are plugged and matched with each other when the L-shaped plate slides. Through the staggered plugging, replacing the direct alignment method, the sealing performance at the connection can be guaranteed.

[0050] Refer to Figures 1 to 6 , wherein, the driving mechanism is configured to drive the corresponding second enclosure to move vertically until the second enclosure and the adjacent surface of the first enclosure 2 are plugged and matched with each other. The first enclosure 2, the second enclosure, and the docking area jointly enclose a space. The driving mechanism includes a first driving unit 30, a gear 31, and a rack 32. Third grooves are recessed on the outer walls of the second enclosures. The groove length of the third grooves is parallel to the wide side of the second enclosures, and racks 32 are arranged along the groove length direction in the third grooves; the first driving unit 30 is provided on the outer wall of the base 1. The output shaft of the first driving unit 30 penetrates the base 1 and is coaxially connected with the gear 31, and the gear 31 meshes with the rack 32.

[0051] Refer toFigures 1 to 8 , a liquid injection mechanism outlet is provided on the inner wall of the space. The liquid injection mechanism inlet is communicated with a fluid source. The liquid injection mechanism includes a spray head 40, a main pipe 41, a first connecting pipe 42 and a second connecting pipe 43. The main pipe 41 is embedded along the length direction on the inner walls of both the first enclosure 2 and the side enclosure 6. The main pipe 41 is provided with the spray head 40, and the spray head 40 constitutes the liquid injection mechanism outlet. Adjacent main pipes 41 are communicated with each other through the first connecting pipe 42. Any main pipe 41 is communicated with the fluid source through the second connecting pipe 43, and the second connecting pipe 43 constitutes the liquid injection mechanism inlet. It should be known that once a self-ignition problem of the parked object occurs, the fire is likely to spread rapidly. Therefore, rapid immersion needs to be achieved. Therefore, by providing the spray heads 40 on the inner walls of both the first enclosure 2 and the side enclosure 6, the water injection speed is significantly increased. A monitoring mechanism is provided on the first enclosure 2. The monitoring mechanism is configured to perform the operation of monitoring the fluid leakage in the space. The monitoring mechanism includes a monitoring meter 50, a first cable 51, a first conductive rod 52, a second cable 53 and a second conductive rod 54. The monitoring meter 50 is provided on the outer wall of the first enclosure 2. The positive terminal of the monitoring meter 50 is electrically connected to the first conductive rod 52 through the first cable 51, and the first conductive rod 52 is grounded. The negative terminal of the monitoring meter 50 is electrically connected to the second conductive rod 54 through the second cable 53, and the second conductive rod 54 is embedded at the bottom of the inner wall of the first enclosure 2. When the monitoring mechanism is actually used, by providing the first conductive rod 52, the first conductive rod 52 is grounded; in cooperation with the second conductive rod 54 being connected to the fluid, when the fluid in the space leaks electricity, a voltage difference will be generated between the first conductive rod 52 and the second conductive rod 54. By observing the reading of the monitoring meter 50, early warning can be carried out to avoid electric shock and has a safety protection effect.

[0052] The liquid discharge device includes a drain tank 80, a third connecting pipe, a filter screen and a valve. A drain groove is opened at the bottom end of the inner wall of the first enclosure 2, and a filter screen is provided at the notch of the drain groove. Considering the complexity of the space placement objects in the parking area, by providing the filter screen at the notch of the drain groove, the sundries that accidentally enter the space are filtered by the filter screen to avoid the problem of blockage of the third connecting pipe. One end of the drain groove is communicated with one end of the third connecting pipe, and the other end of the third connecting pipe is connected to a drain pipe through a second driving unit. A valve is provided on the third connecting pipe. Moreover, after extinguishing the fire, the problem of draining the fluid in the space is also considered. By opening the valve and starting the second driving unit to extract the fluid in the space, the fluid is emptied. After emptying, by operating the driving mechanism in the reverse direction, an electric vehicle fire immersion treatment device is restored to its original state.

[0053] First, the present invention embeds the base 1 in the docking area and sets the first enclosure 2 at the docking area above the outer edge of the base 1. Not only can the first enclosure 2 mark the docking area, but when the docked object does not catch fire spontaneously, the base 1 is embedded in the docking area and will not cause any obstruction to the entry and exit of the docked object from the docking area. Secondly, in cooperation with the driving mechanism for driving the second enclosure, the second enclosure is raised to be flush with the first enclosure 2, so that the first enclosure 2, the second enclosure and the docking area jointly enclose a space. Moreover, since the adjacent two second enclosures are in plug-in fit with each other, and the adjacent surfaces of the second enclosure and the first enclosure 2 are in plug-in fit with each other, it can be obtained that the formed space has high sealing performance and can be used for storing fluids in a closed manner. Finally, by injecting the fluid into the space through the liquid injection mechanism, the fluid submerges the spontaneous combustion part of the docked object. The whole process not only has a large coverage range and can submerge and cover all parts where the docked object catches fire spontaneously, eliminating the fire at the spontaneous combustion part, but also covers the components with thermal runaway of the docked object to prevent re-ignition. In addition, due to the enclosure effect and fluid storage effect of the space, the fire spread path is effectively blocked, avoiding the fire problem of other docked objects, achieving multiple benefits. On this basis, a monitoring mechanism is specially used in cooperation. By monitoring the fluid leakage in the space, early warning is given, achieving a good safety prompt effect.

[0054] Embodiment 2

[0055] Refer to Figure 9 , this embodiment claims to protect an electric vehicle fire immersion treatment method, which applies an electric vehicle fire immersion treatment device. Specifically, the docking area is preferably a ground standard parking space, and the fire of the docked object that catches fire spontaneously in the docking area is treated and extinguished. Among them, the docked object is preferably an electric vehicle. Among them, the fluid source is preferably a fire hydrant, and for water safety, a first solenoid valve is preferably provided in the second connecting pipe 43. The fluid is preferably water, the first driving unit 30 is preferably a motor, the monitoring meter 50 is preferably a voltmeter, and the second driving unit is preferably a water pump. The fluid is preferably water, the filter screen is preferably a metal filter screen. Considering the working conditions, the motor is preferably provided with a protective box to protect the motor, and the valve is preferably a second solenoid valve.

[0056] Including:

[0057] S1. Embed the base 1 in the docking area; specifically, the base 1 is buried in the ground of the standard parking space.

[0058] S2. At least three second enclosures are arranged inside the base 1 to ensure that two adjacent second enclosures are inserted and matched with each other; specifically, the second enclosure arranged inside the wide border 1a is the front enclosure 7, and the second enclosure arranged inside the long border 1b is the side enclosure 6. One end of the side enclosure 6 away from the first enclosure 2 protrudes a second protrusion or recesses a second groove, which forms an insertion and matching with the second grooves or second protrusions recessed on both sides of the side enclosure 6; preferably, the side enclosure 6 protrudes a second protrusion, the second protrusion is perpendicular to the side enclosure 6, and the second protrusion forms an insertion and matching with the second grooves recessed on both sides of the front enclosure 7.

[0059] S3. The first enclosure 2 is arranged at the docking area above the outer edge of the base 1; specifically, the first enclosure 2 extends above the ground of the standard parking space.

[0060] S4. When a fire accident occurs to the parked object, the driving mechanism is activated to drive the second enclosure to move to be inserted and matched with the first enclosure 2, and the first enclosure 2, the second enclosure and the docking area enclose a space; specifically, in an ideal working environment, only one integrated second enclosure is set, and the second enclosure is set as a U-shaped plate structure, which can also meet the requirements of this application. However, considering the actual working situation, due to the limiting effect of the slideway of the base 1 on the second enclosure, designing it as an integrated one will affect the sliding smoothness of the second enclosure. Therefore, preferably, the three second enclosures are independent of each other, and each second enclosure is provided with a corresponding driving mechanism. The structures of the driving mechanisms are the same. During operation, the first driving unit 30 drives the gear 31 to rotate, and the gear 31 can drive the rack 32 to lift through the meshing with the rack 32. Since the rack 32 is embedded in the second enclosure, the second enclosure can be driven to lift. It is worth mentioning that although the lifting of the three second enclosures is independent of each other, since the effect to be achieved in this embodiment is to quickly form a sealed space, the operation progress of the three driving mechanisms is preferably the same.

[0061] S5. The liquid injection mechanism is started to inject fluid into the space to immerse the parked object; specifically, the first solenoid valve is opened to start the fire hydrant, and the water in the fire hydrant flows into the first connecting pipe 42 through the second connecting pipe 43 and then into the main pipe 41. In this way, the tail and both sides of the electric vehicle can be sprayed with water for fire extinguishing through the nozzle 40. The spraying coverage is large, and at the same time, the water accumulates in the space. Generally, it is sufficient to accumulate until the self-ignition area is covered. However, considering that the electric vehicle chassis is also provided with a power supply that is prone to thermal runaway, in combination with the actual situation, it is preferably to stop injecting water when the water accumulates to about half the height of the electric vehicle.

[0062] S6. The monitoring mechanism performs fluid leakage monitoring operations in the space. Specifically, when there is accumulated water in the space, the first conductive rod 52 is grounded, and the second conductive rod 54 is immersed in the water. Therefore, when there is a leakage in the space, there will be a voltage difference between the second conductive rod 54 and the ground, and thus the monitoring meter 50 will show a reading. When the voltage is higher than 24V, the operation is dangerous. Therefore, by observing the reading of the monitoring meter 50, early warning is carried out to avoid electric shock and play a safety protection role.

[0063] S7. After the fire accident is extinguished, the liquid drainage device is activated to drain water. Specifically, the valve is opened, and the water pump pumps water. The water in the space is filtered through the filter screen and then enters the emptying tank 80 and the drain pipe, and finally flows into the sewer network to achieve rapid drainage.

[0064] S8. The driving mechanism reversely drives the second enclosure to reset. Refer to S4 and will not be elaborated here.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
