1 is a perspective view showing a water tank for extinguishing a fire in an electric vehicle according to the present invention.

The electric vehicle fire suppression tank 10 may include a main body 100 , a support part 200 , and a cover part 300 .

The body 100 may include sidewalls 110 , 120 , 130 , 140 and a bottom plate 150 . In addition, the main body 100 forms the exterior of the electric vehicle fire suppression water tank 10 , and can accommodate the electric vehicle and fire extinguishing water in the accommodating space 700 therein.

In addition, the body 100 may be made of a flexible waterproof material that can be folded. That is, as the side walls 110 , 120 , 130 , 140 and the bottom plate 150 are all made of a flexible material, they can be folded, so that they are organized into a small volume and can be easily carried. In addition, since the side walls 110 , 120 , 130 , 140 and the bottom plate 150 are all made of a waterproof material, it is possible to prevent the fire extinguishing water accommodated in the inner accommodation space 700 from leaking to the outside.

In addition, due to the characteristics used for fire suppression of electric vehicles, the body 100 may be made of a material having heat resistance. For example, the body 100 may have a non-combustible glass fiber or high-silica material having heat resistance of 700° C. or higher.

Meanwhile, the support unit 200 may include an edge rod 210 , a support unit 220 , and a fixing unit 230 .

The edge rod 210 is coupled to the sidewalls 110, 120, 130, 140 at the upper portion of the sidewalls 110, 120, 130, 140, and the sidewalls 110, 120, 130, 140 made of a flexible material are fixed It can be kept in shape (eg, rectangular when viewed from above).

Meanwhile, a plurality of supports 220 may be installed on the sidewalls 110 , 120 , 130 , and 140 at predetermined intervals. And the support 220 may support the sidewalls 110 , 120 , 130 , and 140 of the main body 100 .

Specifically, the support 220 may be connected to the edge rod 210 to support the edge rod 210 . That is, the support 220 prevents the edge rod 210 from sinking by gravity, and allows the side walls 110 , 120 , 130 , 140 to maintain a three-dimensional shape.

Meanwhile, the support 220 may include a support rod 223 and a coupling rod 226 .

The support rod 223 is connected to the edge rod 210 and extends downward from the edge rod 210 in an outward direction of the electric vehicle fire suppression tank 10 to form an inclination with respect to the ground.

In addition, the support rod 223 may be fitted to the edge rod 210 , and may be separated from the edge rod 210 when the use of the electric vehicle fire suppression water tank 10 is completed.

In addition, both ends of the coupling rod 226 are connected to the support rod, and may extend parallel to the ground from the lower end of the support rod 223 toward the adjacent support rod.

The plurality of fixing parts 230 may be provided at a predetermined interval on the lower surface of the sidewalls 110 , 120 , 130 , 140 or on the lower surface of the bottom plate 150 . And by fitting the coupling rod 226 to the fixing part 230, the support rod 223 is prevented from escaping in the outward direction of the electric vehicle fire suppression tank 10, and the sidewalls 110, 120, 130, 140) can be maintained in the shape of the lower part.

That is, the support 200 can prevent the edge rod 210 from sinking by gravity, and the side walls 110, 120, 130, 140) can be maintained.

Meanwhile, in a state in which the coupling rod 226 is not fitted to the fixing part 230 , the edge rod 210 and the side walls 110 , 120 , 130 and 140 may be seated on the floor by gravity.

And when a fire occurs in the electric vehicle, the firefighter may first suppress the flame and high-temperature heat, and then the forklift may lift the electric vehicle and then put the electric vehicle down on the bottom plate 150 .

In addition, in a state in which the electric vehicle is seated on the bottom plate 150 , the coupling rod 226 is fitted to the fixing part 230 , so that the side walls 110 , 120 , 130 , 140 may be supported by the support part 200 . Accordingly, the body 100 may have a three-dimensional shape, and an accommodation space 700 may be formed inside the body 100 . And in a state in which the electric vehicle is accommodated in the accommodation space 700 , fire water is supplied to the accommodation space 700 .

Meanwhile, the edge rod 210 may be fixedly coupled to the sidewalls 110 , 120 , 130 , 140 , but is not limited thereto. Specifically, the edge rod 210 may be fitted to the side walls 110 , 120 , 130 and 140 , and when the use of the electric vehicle fire suppression water tank 10 is completed, the edge rod 210 is connected to the side wall 110 , 120, 130, 140). In this case, the rim rod 210 and the body 100 may be transported separately.

Also, the edge rod 210 may include a plurality of sub edge rods. In addition, the plurality of sub rim rods may have a hollow tube shape, and diameters may be different between adjacent sub rim rods. In addition, since the sub-rim rods having a small diameter are fitted to the sub-rim rods having a large diameter, a plurality of sub-rim rods may be connected to each other. And as the plurality of sub-edging rods are separable from each other, transportation can be further facilitated.

Meanwhile, the side wall 120 may include a water outlet 400 for supplying fire extinguishing water to the accommodation space 700 .

On the other hand, a water supply means may not exist at the place where the electric vehicle fires. Therefore, so that the fire engine can directly supply the fire water, the water outlet 400 may be configured to be connectable to the fire engine.

For example, the water outlet 400 may have a 65A standard so that it can be combined with a fire hose (or water outlet of a fire hose) extended from a fire engine, and when the coupling with the fire hose (or water outlet of the fire hose) is released A valve for preventing the fire extinguishing water from being discharged to the outside in the accommodation space 700 may be included.

Meanwhile, the sidewall 120 may include a drain port 500 for discharging fire extinguishing water from the accommodation space 700 .

On the other hand, when a lithium ion battery burns, toxic substances such as hydrogen sulfide and hydrogen fluoride diffuse into the air, and environmental pollution occurs when toxic substances are discharged into the sewer along with fire extinguishing water. Accordingly, in order to collect fire extinguishing water in the accommodation space 700 , the drain port 500 may be configured to be connectable to a waste water vehicle.

For example, the absorption port is 80A standard to prevent the fire water in the accommodation space 700 from being discharged to the outside during fire suppression and to be combined with the waste water pipe extended from the waste water truck after the fire suppression is completed. It may consist of a ball valve.

Meanwhile, in order to seat the electric vehicle on the bottom plate 150 , the upper portion of the main body 100 may be opened.

However, when a lithium-ion battery burns, toxic substances such as hydrogen sulfide and hydrogen fluoride may diffuse into the air and cause environmental pollution.

Therefore, the electric vehicle fire suppression tank 10 may further include a cover part 300 . And in a state where the electric vehicle is seated on the bottom plate 150 and the support part supports the side wall, the cover part 300 closes the opening at the upper part of the body 100, thereby preventing the toxic gas from spreading to the outside. .

Meanwhile, due to characteristics used for fire suppression in electric vehicles, the cover part 300 may be made of a material having heat resistance. For example, the cover part 300 may have a non-combustible glass fiber or high-silica material having heat resistance of 700° C. or higher.

On the other hand, since the main body 100 is made of a flexible waterproof material that can be folded, when the electric vehicle in which an accident has occurred is directly put down on the floor plate 150 of the main body 100, the floor plate is caused by the sharp part of the electric vehicle in which the accident occurred. (150) may be damaged.

Accordingly, the electric vehicle fire suppression tank 10 may further include a protection plate disposed on the bottom plate 150 . And the electric vehicle can be seated on the protective plate. In addition, the protection plate may include at least one of a floor panel unit and a safety footrest. This will be described with reference to FIG. 2 .

2 is a plan view illustrating a floor panel unit according to the present invention. It will be described with reference to FIG. 1 together.

The electric vehicle fire suppression tank 10 may further include a floor panel unit 600 .

The bottom panel unit 600 may be disposed on the bottom plate 150 described with reference to FIG. 1 , and may be separated from the bottom plate 150 .

Specifically, the floor panel unit 600 may be coupled to the floor plate 150 by an adhesive means or a fastening mechanism, and may be separated from the floor plate 150 when fire suppression is completed. Also, the floor panel unit 600 may be simply seated on the bottom plate 150 without the bottom panel part 600 being coupled to the bottom plate 150 by an adhesive means or a fastening mechanism.

As the bottom panel part 600 is detachable from the bottom plate 150 , the main body 100 and the bottom panel part 600 may be transported separately.

Meanwhile, when the floor panel unit 600 is disposed on the bottom plate 150 of the body, the electric vehicle may be seated on the floor panel unit 600 .

That is, when a fire occurs in the electric vehicle, the firefighter may first suppress the flame and high-temperature heat, and may arrange the floor panel part 600 on the bottom plate 150 of the main body. Then, the forklift may lift the electric vehicle and put the electric vehicle down on the floor panel unit 600 .

Meanwhile, the bottom panel unit 600 may be formed integrally, but is not limited thereto, and may include a plurality of panels 610 , 620 , 630 , 640 , 650 , 660 , 670 , 680 as shown in FIG. 2 . have.

In this case, the plurality of panels 610 , 620 , 630 , 640 , 650 , 660 , 670 , and 680 are separable from each other, and may be disposed on the bottom plate 150 in combination with an adjacent panel.

For example, a protrusion and a groove are respectively formed on a side surface of a specific panel, and the protrusion of a specific panel may be fitted with a groove of an adjacent panel, and the groove of a specific panel may be fitted with a protrusion of an adjacent panel, respectively. For another example, each of the plurality of panels 610 , 620 , 630 , 640 , 650 , 660 , 670 and 680 may be coupled to an adjacent panel by a separate fastening mechanism.

Although it has been described that eight panels are disposed in FIG. 2 , the present invention is not limited thereto. For example, the plurality of panels may be composed of 6 sheets of light non-combustible fiber-reinforced plastic (FRP) with a size of 167.75 × 183 cm.

As such, when the bottom panel unit 600 includes a plurality of panels 610, 620, 630, 640, 650, 660, 670, 680, a plurality of panels 610, 620, 630, 640, 650, 660, 670, 680) can be separated and transported, so transport to the fire site is facilitated.

Meanwhile, in addition to the floor panel unit 600 , an additional reinforcing mechanism may be disposed on the floor panel unit 600 .

Specifically, the electric vehicle fire suppression tank 10 may include safety footrests (810, 820, 830, 840). In this case, four safety footrests can be arranged.

The safety footrests 810 , 820 , 830 , and 840 may be disposed where the wheels of the electric vehicle come into contact with, and may be made of 60×60×10 cm aluminum or plate (PE) material.

When the safety scaffolds 810 , 820 , 830 , and 840 are installed, the electric vehicle is seated in a higher place due to the thickness of the safety scaffolds 810 , 820 , 830 , 840 . Accordingly, it becomes easier to lift the electric vehicle with a forklift in a state where fire suppression is completed, and damage to the floor plate 150 or the floor panel unit 600 can be reduced.

As the protection plate, the floor panel unit 600 may be used, or both the floor panel unit 600 and the safety footrests 810 , 820 , 830 , and 840 may be used. In addition, only the safety footrests 810 , 820 , 830 , and 840 may be used without the floor panel 600 being used as the protection plate.

Meanwhile, the safety footrests 810 , 820 , 830 , and 840 may also be separated from the floor panel unit 600 or the floor plate 150 .

On the other hand, when fire-fighting water is supplied through the water outlet 400 , the fire water falls to the bottom plate 150 . Accordingly, a sprinkler may be additionally installed in order to supply fire-fighting water and directly spray fire-extinguishing water to the vehicle body of the electric vehicle.

This will be described with reference to FIG. 3 .

3 is a perspective view showing a water tank for fire suppression of an electric vehicle installed with a sprinkler according to the present invention.

The sprinkler 900 may be detachably installed in the main body 100 , and may spray fire water toward the accommodation space 700 . To this end, the sprinkler 900 may include a pipe 910 , a head 920 , and a sprinkler inlet 930 .

The body 100 may include a plurality of pipe fixing parts 160 installed on some or all of the plurality of side walls 110 , 120 , 130 , and 140 . For example, a total of eight pipe fixing units 160 may be installed on the inner surfaces of the side walls 110 , 120 , 130 , and 140 .

Here, the pipe fixing part 160 may be fixed to the inner surface of the side walls 110 , 120 , 130 , 140 by an adhesive or other fastening means.

Meanwhile, the pipe 910 of the sprinkler 900 is a pipe through which the fire water supplied from the outside moves to the sidewall type head, and may be detachably mounted to the pipe fixing unit 160 .

This will be described with reference to FIG. 4 .

Figure 4 is a view for explaining a pipe coupled to be detachably coupled to the pipe fixing portion according to the present invention.

The pipe fixing part 160 may include a fixing body 161 , a first arm 162 , and a second arm 163 .

The fixed body 161 may be coupled to the sidewalls 110 , 120 , 130 , and 140 , and the first arm 162 and the second arm 163 are integrally formed with the fixed body 161 , and the fixed body ( 161) can protrude.

In addition, the first arm 162 and the second arm 163 may have a shape curved toward each other in a streamlined manner, and may be formed in a structure symmetrical to each other.

In addition, when the pipe 910 is pushed in, the first arm 162 and the second arm 163 may wrap the outer circumferential surface of the pipe 910 while resiliently opening, and the first arm 162 and the second arm The pipe 910 may be closely fixed to the pipe fixing part 160 by the elastic force of 163 .

Meanwhile, since the pipe 910 can be separated from the pipe fixing unit 160 , the pipe 910 and the body 100 can be transported separately.

Also, the pipe 910 may include a plurality of sub pipes, and the plurality of sub pipes may be separable from each other. When a plurality of sub-pipes are separable from each other, transportation may be easier.

Meanwhile, the pipe 910 may be installed on some or all of the plurality of side walls 110 , 120 , 130 , and 140 by being coupled to the pipe fixing unit 160 .

In addition, the pipe 910 may be composed of a light and strong heat-resistant connection-type synthetic resin pipe (CPVC).

Returning to 3 again, the plurality of heads 920 may be connected to the pipe 910 to receive fire extinguishing water from the pipe 910 . And the sidewall head 920 may spray the fire extinguishing water toward the receiving space 700 inside.

In this case, the head 920 may be a sidewall type head. That is, when a general head is used, the fire extinguishing water sprayed from the head 920 is ejected to the upper portion of the accommodation space 700 , which reduces the effectiveness of fire suppression. Therefore, by using the side wall type head, fire extinguishing water can be sprayed in the direction 921 of the accommodation space 700 .

Meanwhile, the sprinkler water inlet 930 may supply fire extinguishing water supplied from the outside to the pipe 910 .

On the other hand, a water supply means may not exist at the place where a fire occurs in the electric vehicle, and even if there is a water supply means, it may have a low water pressure. Therefore, the sprinkler water inlet 930 may be configured to be connectable to the fire engine so that the fire engine can directly supply the fire water. In this case, the pipe 910 may receive fire extinguishing water from the fire engine through the sprinkler water inlet 930 .

For example, the sprinkler water outlet 930 may be formed of an open/close fire hose coupling metal fitting capable of being coupled to a 40A fire hose (or a fire hose outlet) extending from a fire engine. In addition, the sprinkler water outlet 930 may include a valve for adjusting the pressure of the fire extinguishing water sprayed from the head 920 .

Additionally, the electric vehicle fire suppression tank 10 may further include a pressure gauge, a water level gauge, and a digital temperature gauge.

Here, the pressure gauge may be installed to adjust the water pressure of the sprinkler 900 , and the water level gauge may be installed to calculate the amount of water stored in the accommodation space 700 .

In addition, the digital temperature measuring device may be installed in order to check the stabilization state of the electric vehicle by measuring the temperature change of the fire extinguishing water in the accommodation space 700 .

According to the emergency response manual of the electric vehicle manufacturer, if a fire occurs in the lithium-ion battery in the electric vehicle, it takes up to 24 hours to extinguish the fire. cases occur. And according to the present invention, when a fire occurs in an electric vehicle, there is an advantage in that it is possible to extinguish the fire early by submerging the electric vehicle in a water tank for fire suppression of the electric vehicle at the scene of the accident, and it takes a long time to extinguish the fire. It has the advantage of significantly reducing the input of

In addition, according to the present invention, since the main body is made of a flexible waterproof material that can be folded and can be mounted and detached between the support part, floor panel part, sprinkler, etc., it is possible to easily transport the electric vehicle fire suppression tank to the fire site It also has the advantage of reducing the storage space.

In addition, according to the present invention, since water supply in the water tank and water supply to the sprinkler can be performed using a fire engine, there is an advantage that fire suppression using the water tank is possible even in a place where no water supply means is provided.

In addition, according to the present invention, when fire suppression is completed, contaminated fire fighting water can be collected using a waste water truck, and the waste water truck can recover the entire amount of contaminated fire water and discard it at the wastewater terminal treatment plant, thereby reducing environmental pollution. There are advantages to avoiding it.

In addition, according to the present invention, by closing the opening of the upper body with the cover portion, there is an advantage of preventing the toxic gas from spreading to the outside.

The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded.
