Description

{quick installation water tank for electric vehicle fire suppression}

The present invention relates to a quick installation water tank for extinguishing fires in electric vehicles. More specifically, when a fire occurs in an electric vehicle, the vehicle is not directly lifted and immersed in the water tank, but is folded during storage and transportation, and the fire vehicle remains in place when used. It is a structure that quickly expands towards the fire vehicle, descends from above the fire vehicle, is installed to surround the fire vehicle, and is filled with water inside, so that in the event of an electric vehicle fire, the fire can be extinguished from the battery part at the bottom of the vehicle as quickly as possible without time delay. This is about a quick-installation water tank for electric vehicle fire suppression that can be easily and safely performed.

In general, with the number of registered electric vehicles in the country exceeding about 140,000, fires are frequent and even fatal accidents are occurring, so it is pointed out that safety measures are urgently needed.

While the automobile industry has already declared 2021 as the first year of popularization of electric vehicles, anxiety about the safety of electric vehicles is currently growing. This is because there is no clear way to solve the problems facing us, such as a series of fire accidents of unknown cause and difficulties in suppression and rescue.

Electrical factors were the most common cause of vehicle fires, accounting for 58.0%. This is presumed to be caused by the battery and related parts or electric shock. Meanwhile, the cause was unknown in 14.5% of cases. In addition, there were mechanical factors (14.5%), traffic accidents (7.0%), and carelessness (3.0%).

Electric vehicles have a drive storage battery (battery) that stores a very high capacity of energy placed on the bottom of the vehicle, and when ignition starts due to an accident or other reasons, the temperature at the hot point is very high and even if the fire is superficially extinguished, the high density Suppression of fires becomes very difficult due to the type of battery integrated into the battery and the resulting re-ignition phenomenon due to continuous heat transfer.

An example of a water tank for extinguishing electric vehicle fires according to the prior art is disclosed in Republic of Korea Patent Registration No. 10-2431474 (registered on August 8, 2022, hereinafter referred to as 'Patent Document 1').

However, the water tank for extinguishing electric vehicle fires according to the prior art is provided with an air-injection type tube, so when a fire occurs in an electric vehicle, air is injected into each tube to inflate it, and the inside of the water tank is filled with water before the already burning vehicle is lifted. Because it has to be lifted by the back and submerged into a water tank, it takes too much time to prepare in advance for fire suppression, which can delay fire suppression. Also, because a burning vehicle has to be lifted and placed into a water tank, it can cause fire damage during the fire suppression process. There is a problem that safety accidents such as transfer and sticking may occur.

On the other hand, even if a water tank was prepared to surround a burning vehicle by assembling a certain frame in the past, too much time was consumed in the process of preparing the water tank, and a certain amount of separation distance had to be secured to fit the frame of the water tank around the burning electric vehicle. As the area of the water tank becomes excessive, there is a problem that the amount of water consumed to fill the inside of the water tank may become too enormous.

Republic of Korea Patent Registration No. 10-2431474 (registered on August 8, 2022)

The purpose of the present invention is to have a structure in which, in the event of a fire in an electric vehicle, the vehicle is not directly lifted and submerged in a water tank, but is folded during storage and transportation and quickly unfolded toward the fire vehicle while the fire vehicle remains in place when used.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

As shown in Figures 1 to 4, the quick installation water tank for extinguishing electric vehicle fires according to the present invention is folded in a flat state during storage or transportation, and can surround the vehicle 10 in the event of a vehicle fire. A blocking wall assembly 100 is provided to be expanded in a fire blocking state (see FIG. 2) to form a rectangular side exterior shape in plan, and is connected to the upper part of the blocking wall assembly 100 by a rotating link 210, blocking in plan. It is provided to be located in the center of the wall assembly 100 so that when the blocking wall assembly 100 is installed on the ground to extinguish a vehicle fire, the blocking wall assembly 100 is quickly unfolded from a folded state to a fire blocking state by its own weight. After the blocking wall assembly 100 is unfolded in a fire-blocking state and is provided at the lower part of the blocking wall assembly 100, the water filled into the inside of the blocking wall assembly 100 flows into the blocking wall assembly 100. ) and includes a flame-retardant watertight assembly 300 provided to prevent leakage to the outside and to prevent damage by flame.

Accordingly, as shown in FIG. 2, when a fire occurs in an electric vehicle, the vehicle is not directly lifted and immersed in a water tank, but is folded during storage and transportation, and when used, the fire vehicle 10 is placed in the same state as the fire vehicle 10. ) is installed to surround the fire vehicle 10 and surround the fire vehicle 10 with a structure that quickly expands toward We can provide a quick-installation water tank for electric vehicle fire suppression that can be easily and safely performed as quickly as possible without delay.

As shown in FIGS. 1 and 2, the blocking wall assembly 100 is a pair of blocks that are spaced apart and symmetrical from each other, are as close to each other as possible in the folded state, and are provided to form one side of a rectangular width in plan in the fire blocking state. It includes a reciprocating wall 110 and a pair of folding walls 120 that are connected between the pair of reciprocating walls 110 with a hinge structure so that they can be folded and are provided to form the width of the other side of the rectangle in plan in a fire blocking state. do.

Accordingly, during storage or transportation, the blocking wall assembly 100 is folded in a folded state and stacked on top of each other, making it convenient for both storage and transportation. Then, when a fire occurs in an electric vehicle, it is transported to the site and used as a blocking wall by a crane, etc. When the four corners of the upper part of the assembly 100 are hung and lifted, the folded wall 120 is gradually unfolded due to the pressure caused by the weight of the heavy body 200, and the blocking wall assembly 100 is connected to the electric vehicle 10. It can be unfolded within a short period of time to form a rectangular side exterior shape with both top and bottom open in a fire-blocking state that can surround the vehicle, so it can be used in the process of directly lifting an electric vehicle that has already started a fire and putting it into a water tank filled with water. The fire extinguishing process can be made safer by leaving the fire vehicle 10 as it is without the risk of the fire spreading further, and filling it with water after the water tank comes down from above and surrounds it.

Here, both the reciprocating wall 110 and the folding wall 120 are prepared to be as thin as possible to lighten the weight and include plates made of metal such as iron or stainless steel that are resistant to fire, and are used to structurally reinforce these plates. It is made up of a frame made of each pipe and angles.

On the other hand, when the blocking wall assembly 100 is fully expanded in a fire blocking state, the length of the width corresponding to the distance between the pair of folded walls 120 on the plane (the length of the reciprocating wall 110) is approximately 4.5. Approximately 6.5 m, the length of the hem width corresponding to the distance between the pair of reciprocating walls 110 (length when the folded wall 120 is fully unfolded) is approximately 2.5 to 3.5 m. , it is preferable that the height of the blocking wall assembly 100 when installed on the ground is approximately 1 m.

Accordingly, when the blocking wall assembly 100 is expanded as much as possible in a fire blocking state to form a rectangular shape open up and down, electric vehicles 10 of any size can be easily wrapped from above, and other fire trucks or water trucks at the site can be easily wrapped. If the water supplied from the vehicle is immediately filled into the interior of the blocking wall assembly 100, the battery at the bottom of the fire vehicle 10 can be easily submerged in water first, allowing the fire in the vehicle 10 to be extinguished as quickly as possible. , a blocking wall assembly 100 and a blocking wall assembly 100 that can be folded in advance without the need to individually assemble the frame of the water tank from a distance to avoid the fire spreading around the already burning electric vehicle 10. The amount of water filled into the water tank can be reduced to less than half compared to the conventional method by the weight body 200, which automatically forms a water tank just by lifting it and lowering it toward the fire vehicle 10, thereby saving water resources, protecting the environment, and protecting the environment. Cost savings can be achieved.

As an embodiment of the present invention, as shown in FIG. 1, it is preferable that both ends of the reciprocating wall 110 are provided with anti-slip stoppers 111 bent 90° inward and extending toward the folding wall 120. .

Accordingly, when a fire occurs in an electric vehicle, the blocking wall assembly 100 is transported to the site and the four upper corners of the blocking wall assembly 100 are hung and lifted by a crane, etc., due to the weight of the heavy body 200. The folded wall 120 is gradually unfolded by pressure, and after the blocking wall assembly 100 is fully unfolded to a fire-blocking state capable of surrounding the electric vehicle 10, the inside is filled with water and internal water pressure is applied. Even if the folded wall 120 opens outward and is deformed, it can be blocked and fixed by the anti-slip stopper 111, preventing the shape of the blocking wall assembly 100 from being deformed by internal water pressure in a fire blocking state. This prevents damage and ensures that the shape of the water tank remains solid.

Here, the length of the anti-slip stopper 111 extended by bending inward from both ends of the reciprocating wall 110 toward the folded wall 120 is approximately 0.14 to 0.23 times the length when the folded wall 120 is fully unfolded. It is desirable to ensure that arrangements are made.

Accordingly, even if the blocking wall assembly 100 is completely unfolded in a fire-blocking state, the inside is filled with water and internal water pressure is applied, the folded wall 120 is pushed outward and is prevented from being deformed by the anti-slip stopper 111. It can be blocked and prevented.

At this time, if the extended length of the anti-slip stopper 111 is less than 0.14 times the length of the folded wall 120, it may not properly prevent the outward deformation of the folded wall 120 due to internal water pressure, and if it exceeds 0.23 times. Otherwise, the unfolding and retraction of the folded wall 120 may not be performed properly.

As shown in FIGS. 1 and 5, the folding wall 120 is connected with a hinge structure so that it can be folded inward between a pair of reciprocating walls 110, and the middle portion of the folding wall 120 is folded. A folding hinge 121 is provided in a plurality of parts vertically and connects the folded wall 120 to be folded and unfolded, and extends inward through the folded part from one part and the other part that are mutually folded in a plane. It includes a folding stopper (123) provided as required.

Accordingly, the space occupied when the blocking wall assembly 100 is folded can be minimized by connecting the folding wall 120 with a hinge structure between the pair of reciprocating walls 110 so that it can be folded inward. The folding hinge 121 allows the folding wall 120 to be easily folded inward, and after the blocking wall assembly 100 is fully unfolded in a fire blocking state, the inside is filled with water and internal water pressure is applied. Even if the folded wall 120 is pushed outward and deformed, it can be prevented more firmly by the folding stopper 123 together with the anti-slip stopper 111.

Here, the length of the folding stopper 123 extending inward from the folded wall 120 past the folded portion is approximately 0.12 to 0.19 times the length from one side to the other side where the folded wall 120 is folded. It is desirable to ensure that this is properly prepared.

Accordingly, even if the blocking wall assembly 100 is completely unfolded in a fire-blocking state and the interior is filled with water and internal water pressure is applied, the folded wall 120 is pushed outward and deformed, folding together with the anti-slip stopper 111. It can also be blocked more firmly by the stopper 123 to prevent it.

At this time, if the extended length of the folding stopper 123 is less than 0.12 times the length from one side to the other side where the folding wall 120 is folded, outward deformation of the folding wall 120 due to internal water pressure is prevented. It may not be properly blocked, and if it exceeds 0.19 times, the unfolding and retraction of the folded wall 120 may not be performed properly.

Meanwhile, as shown in FIGS. 1 and 3, the blocking wall assembly 100 is provided between the reciprocating wall 110 and the folding wall 120 so that the folding wall 120 is positioned with respect to the reciprocating wall 110. A wall hinge 130 that rotates, and a lifting hook 140 provided at the four corners of the upper part of the blocking wall assembly 100 to allow the blocking wall assembly 100 to be lifted while hanging on a lifting means such as a crane. Includes more.

As shown in FIGS. 1 to 3, one side of the weight body 200 is rotatably connected to the weight body 200 and the other side is connected to the blocking wall assembly 100 in an 'X' shape. A rotating link 210 that is connected to be able to rotate in one direction, and the other end of the rotating link 210 is rotatably connected to the upper end, is raised and lowered on the blocking wall assembly 100, and a lifting height adjuster 220 is provided to adjust the height. ) includes.

Accordingly, when a fire occurs in an electric vehicle, the blocking wall assembly 100 is transported to the site and the lifting hook 140 of the blocking wall assembly 100 is hung and lifted by a crane, etc., and the weight of the heavy body 200 is lifted. The rotating link 210 is rotated by the pressure, and the pair of reciprocating walls 110 push the reciprocating walls 110 apart from each other, and the blocking wall assembly 100 gradually unfolds smoothly, and the blocking wall assembly ( 100) can be fully unfolded in a fire-blocking state that can surround the electric vehicle 10, and can be placed at the height of the fire vehicle 10 so as not to touch the fire vehicle 10 when the heavy body 200 is lowered by its own weight. The maximum descending height of the weight body 200 is easily adjusted by the lifting height control unit 220 so that the unfolding of the blocking wall assembly 100 due to the descent by the weight of the weight body 200 is blocked in the middle. We can make sure it happens smoothly without any problems.

As an embodiment of the present invention, as shown in FIGS. 3 and 5, the other ends of the rotating links 210 are symmetrically connected to the middle portion of the reciprocating wall 110, and the lifting height adjustment unit 220 It is preferable that each reciprocating wall 110 is provided with a piston lifting structure.

Accordingly, even in the event of an electric vehicle fire of an acceptable size, the blocking wall assembly 100 can easily surround the electric vehicle 10 to block the fire and form a water tank that can be easily extinguished.

However, in this case, it is desirable to make the weight of the weight 200 somewhat heavier so that the downward pressure due to its own weight is stronger.

Meanwhile, as an embodiment of the present invention, as shown in FIG. 3, the other ends of the rotating links 210 are described as being symmetrically connected to the middle portion of the reciprocating wall 110, but in another embodiment of the present invention As an embodiment, as shown in FIG. 6, the other ends of the rotating links 210 are symmetrically connected to the upper parts of the lifting height adjusters 220 provided vertically at both ends of the reciprocating wall 110, respectively, to provide a small It can also be used for fire suppression in the event of a fire in a small or medium-sized electric vehicle (10).

Here, the weight of the weight body 200 is preferably approximately 1.2 to 1.6 times the weight of the barrier wall assembly 100.

Accordingly, when a fire occurs in an electric vehicle, the blocking wall assembly 100 is transported to the site and the lifting hooks 140 on the upper portions of the four corners of the blocking wall assembly 100 are hung and lifted by a crane or the like. The folded wall 120 is gradually unfolded due to the pressure exerted by its own weight (200), and the blocking wall assembly 100 can be completely and smoothly unfolded in a fire-blocking state that can surround the electric vehicle 10.

At this time, if the weight of the weight body 200 is less than 1.2 times the weight of the blocking wall assembly 100, the pressurization due to its own weight may be somewhat weakened, preventing the blocking wall assembly 100 from unfolding properly, and if the weight of the weight body 200 is less than 1.6 times the weight of the blocking wall assembly 100, the pressure due to its own weight may be somewhat weakened. The pressure due to the weight of the surface weight body 200 becomes so strong that the weight body 200 falls at too fast a speed, so that when the blocking wall assembly 100 is unfolded, the amount of impact applied to the blocking wall assembly 100 becomes too large. At least one of the rotating link 210 and the blocking wall assembly 100 may easily be broken or damaged.

As an embodiment of the present invention, it is preferable that when the weight of the blocking wall assembly 100 is approximately 657 kg, the weight of the mass 200 is provided to be approximately 1,000 kg.

As shown in FIGS. 3 and 4, the flame-retardant watertight assembly 300 has cross-sections that are mutually symmetrical in the shape of an 'L' inward and outward from the lower part of the blocking wall assembly 100, respectively, and is formed in the blocking wall assembly 100. ) and a base square pipe 310 that extends long along the longitudinal direction of each side and is provided in the lower part of each side of the blocking wall assembly 100, and is rolled and fixed to each base square pipe 310 to form a blocking wall in a fire blocking state. When the assembly 100 is unfolded, the flame retardant cloth 320 is provided to extend to a width corresponding to the length of each base square pipe 310 toward the inside of the space formed by the blocking wall assembly 100, and the fire retardant cloth 320 A pair of fixing bars 330 are rolled and inserted between each side of the blocking wall assembly 100 and the base square pipe 310 so that the flame retardant cloth 320 is detachably coupled to the lower part of the blocking wall assembly 100. , It is provided to be surrounded by a flame retardant cloth 320 at the lower part of the base square pipe 310, and when the blocking wall assembly 100 is unfolded in a fire blocking state, the fire retardant cloth 320 is placed on the ground from the lower part of the blocking wall assembly 100. It includes a watertight pressing member 340 made of an elastic material so as to be in close contact with the watertight state.

Accordingly, when a fire occurs in the electric vehicle 10, the blocking wall assembly 100 is transported to the scene and lowered by its own weight so that it can surround the fire vehicle 10. ) is fully unfolded and installed on the ground in a fire blocking state, and then the interior of the blocking wall assembly 100 is filled with water supplied from other fire trucks or water trucks on site, between the lower part of the blocking wall assembly 100 and the ground. By blocking the gap as much as possible with the flame-retardant watertight assembly 300, water escaping through the lower part of the blocking wall assembly 100 can be minimized by the flame-retardant watertight assembly 300, thereby reducing water consumption as much as possible.

That is, the amount of water filled inside the blocking wall assembly 100 that is fully expanded in a fire blocking state and confined by the fire-proof watertight assembly 300 according to the present invention is supplied from a fire truck or water tank to the inside of the blocking wall assembly 100. Approximately 90% or more of the amount to be poured can be maintained as is.

As shown in FIG. 4, the base square pipe 310 is mutually symmetrical in the shape of an 'ㄴ' shape inward and outward, respectively, at the lower part of the reciprocating wall 110 and the folding wall 120 of the blocking wall assembly 100. It is made of U-shaped steel to have a cross section, and is welded and joined to the lower part of the reciprocating wall 110 and the folding wall 120.

Here, the fixing bar 330 is provided to be fixed by inserting and closely contacting the inside of the base square pipe 310 with the flame retardant cloth 320 in a rolled state, and the upwardly bent portion of the cross section of the base square pipe 310 is slightly inclined inward. The fixing bar 330 may be more firmly engaged by forming a portion or having an additional portion that is bent and extended back inward from the top.

As shown in FIG. 4, the flame retardant cloth 320 is made of a material containing non-combustible fibers and is provided so that it can be replaced after one use, and after the blocking wall assembly 100 is fully unfolded in a fire blocking state. is preferably provided to extend approximately 50 to 100 cm inward from each side.

The fixing bar 330 is preferably made of a metal material such as iron or stainless steel.

As shown in FIG. 4, the watertight pressing member 340 is made of an elastic urethane foam rubber material, and its lower portion is formed to be convex toward the ground.

Accordingly, even if the ground on which the blocking wall assembly 100, which is fully expanded in a fire blocking state, is installed is uneven and uneven, the fire retardant fabric 320 is tightly adhered to the ground by the watertight pressurizing member 340, making it firmly watertight. By doing so, the water blocking function by the flame retardant watertight assembly 300 can be effectively achieved.

Meanwhile, as another embodiment of the present invention, as shown in FIG. 7, a plurality of installation rollers 350 in rolling motion are installed at the lower part of the flame retardant fabric 320 that surrounds the watertight pressing member 340 and is in contact with the ground. You can also have it provided.

Accordingly, even when the blocking wall assembly 100 first contacts the ground in an erected state and is in the process of unfolding in a fire blocking state, the unfolding process of the blocking wall assembly 100 is caused by the rolling motion of the installation rollers 350. This can be done smoothly, and direct contact of the flame retardant fabric 320 with the ground is avoided, preventing wear and damage to the fire retardant fabric 320, thereby preventing flame retardation when water fills the inside of the blocking wall assembly 100. It is also possible to prevent water from leaking through worn and damaged parts of the cloth 320.

Although the technical aspect has been described above and in the accompanying drawings, the technical idea of the present invention is for explanation purposes only and is not intended to be limiting, and those skilled in the art will understand the present invention. It will be understood that various modifications and changes can be made to the technical idea of the present invention without departing from the technical scope described in the claims, which will be described later.
