In recent years, electric vehicles have rapidly spread, and electric vehicle charging stations are gradually increasing. However, a fire often occurs while an electric vehicle is being charged at a charging station, which has emerged as a social problem. In particular, when a fire breaks out in an underground garage, a fatal threat to residents may occur due to rapidly increasing toxic gas and fire spread in an enclosed space.

In the case of an electric vehicle fire, there was a problem in that it was impossible to extinguish the fire with the existing automatic fire extinguishing system (sprinkler) or fire extinguisher because the flash over occurred in a very short time and the fire extinguishing agent did not reach the battery mounted on the lower part of the vehicle body. .

In order to solve this problem, Republic of Korea Patent Registration No. 10-2431474 proposed a method of forming a water tank and immersing the battery in water filled in the water tank to extinguish the fire. However, the conventional water tank forming apparatus has a problem in that the installation structure is complicated and the production cost is high, and since the tube has to cover the parking line, an extra place and area for installing the tube are required, which is actually due to space constraints. has problems with installation.

In addition, since the entire cross-sectional area of the tube must be filled with water, a large amount of water must be secured, resulting in a unit cost problem, and it takes a lot of time to submerge the battery in water by filling the water tank, resulting in a problem in effectiveness.

In addition, it is preferable to build in such a way that the electric vehicle 2 is placed on the mat 400 and parked in a state where the mat 400 is placed on the ground 1. For this reason, as will be described later, since the mat portion 400 forming the water tank only needs to be positioned below the electric vehicle 2 (the area where the mat portion 400 is placed is structurally an area for the electric vehicle to park, the electric vehicle is an essential area that must inevitably be secured for parking), and unlike the prior art, a new place or area for installing the tube along the parking line is not additionally required. Therefore, unlike the prior art, it is an effective form that can actually be installed in an underground parking lot.

The waterproof fabric 402 is coupled to the side of the mat portion 400 or the combined tarpaulin 402 is placed under the mat portion. For convenience of description, if the part of the mat part 400 supporting the electric vehicle 2 is referred to as the mat part body 401, the waterproof cloth 402 is coupled or coupled to the side of the mat part body 401. The tarpaulin 402 is located under the mat body 401.

More specifically, it is preferable that the tarpaulin 402 is folded at the edge of the mat unit body 401 before operation, and it is preferable that the tarpaulin 402 is positioned within the parking line. As will be described later, when the wire portion 500 connected to the plurality of points of the tarpaulin 402 is wound, the tarpaulin 402 separates from the lower part of the mat body 401 and moves up and down to form a partition wall.

One end of the wire part 500 is coupled to the first roller part 300 and the other end is connected to the side of the mat part 400 or coupled to a point of the tarpaulin 402 laid under the mat part. Referring to FIG. 1 , the wire part 500 is preferably connected to the side of the mat part 400 or coupled to the longitudinal end of the tarpaulin 402 laid under the mat part.

The pin unit 700 is coupled to the frame unit 200 . The pin part 700 serves to support the wire part 500 and may be formed in plural. The pin part 700 extends in the width direction and is preferably installed adjacent to the second roller part 600 in the length direction.

The third roller unit 900 is coupled to an upper portion of the pillar unit 100 and serves to support the wire unit 500 . In addition, it is formed near the junction of the pillar part 100 bent in the shape of 'L' and the frame part 200, and is used as a role for maintaining the wire part 500 in the same shape as shown in FIG. The third roller unit 900 is rotatable, and the wire unit 500 is seated on the third roller unit 900, but is not wound.

Referring to FIGS. 1 and 5 , the structure of the second roller unit 600 and the pin unit 700 and the installation structure of the wire unit 500 will be described. 5 is an enlarged view of a part of the inside of the frame unit 200 .

First, with reference to FIG. 5 , the structure of the second roller unit 600 and the pin unit 700 and the support structure of the wire unit 500 will be described.

The second roller unit 600 has a roller shape extending in the width direction, is located in the hollow part 201 in the frame unit 200, and both ends are rotatable on a pair of side surfaces of the frame unit 200, respectively. combined to do The fin unit 700 also has a structure extending in the width direction, and is preferably located adjacent to the second roller unit 600 in the longitudinal direction, and may be formed in plural. At this time, it is preferable that the pin unit 700 is installed to be detached from the frame unit 200 by external pressure.

The wire part 500 supported by the third roller part 900 extends in the longitudinal direction, is supported so as to be wound around the second roller part 600, and the direction is changed. In addition, the wire part 500 whose direction is changed is formed to extend in the longitudinal direction, and is formed in a structure supported by the pin part 700 by coming into contact with the upper part of the pin part 700 .

Thereafter, while being supported by a plurality of second roller parts to be described later, it extends in the direction of the pillar part 100, extends along the vertical direction of the pillar part 100, and is bent in the vicinity of the ground 1 again to the ground ( It is formed extending in the longitudinal direction along 1), and the end is preferably connected to the side of the mat part 400 or coupled to one point 410 of the tarpaulin 402 laid under the mat part. In order to maintain the above-described structure, a separate detachable fixing device such as a pin may be coupled to the pillar portion 100 .

Therefore, the wire unit 500 is installed in the structure shown in FIG. 1, and there is an advantage in that interference of the wire unit 500 does not occur while the electric vehicle 2 is parked. It has the advantage of being able to minimize exposure, improving aesthetics, minimizing malfunctions, and increasing lifespan.

When a fire occurs while the electric vehicle 2 is parked, the first roller unit 300 is rotated through a separate detection sensor and a control system (not shown). 2 and 3 show a process of creating a water tank with the system according to the present invention when a fire occurs in an electric vehicle.

First, referring to FIG. 2 , for example, when the first roller unit 300 rotates counterclockwise, one end of the wire unit 500 is wound around the first roller unit 300 . At this time, a structure in which the entire wire portion 500 is pulled toward the first roller portion 300 during the winding process is formed. In particular, since the wire unit 500 after being changed in direction through the second roller unit 600 is not constrained by the roller and is only supported by the pin unit 700, the entire wire unit 500 is pulled. In this case, the position of the wire part 500 after the direction is changed through the second roller part 600 is changed to approach the second roller part 600, and the pin part 700 supporting it is the wire part. 500 is removed by a pulling force. In addition, as described above, the other end of the wire part 500 is coupled to one point 410 of the tarpaulin 402 connected to the side of the mat part 400 or laid under the mat part, so the mat part 400 A point 410 of the tarpaulin 402 connected to the side of the mat or laid under the mat also moves in response to the movement of the wire part 500, and upward toward the second roller part 600 as shown in FIG. The structure of a part of the mat part 400 and the connection of the mat part 400 or the tarpaulin 402 laid under the mat part is partially changed so as to move up and down.

Next, referring to FIG. 3 , when the wire unit 500 is wound around the first roller unit 300 by a certain length, the wire unit 500 is tensioned between the second roller unit 600 and the mat unit in a state in which tension is formed. It is located between a point 410 of a tarpaulin 402 connected to or laid under a mat portion of 400. In this state, a point 410 of the tarpaulin 402 connected or laid under the mat part is in a state of being lifted in a more vertical direction than the state of FIG. 2, and through this, the mat part 400 ) and the mat part 400 or connected to the tarpaulin 402 laid under the mat part to form a partition wall.

Therefore, a part of the mat part 400 and a tarpaulin 402 connected to the mat part 400 or laid under the mat part 402 are formed only by an operation in which the first roller part 300 rotates in one direction and the wire part 500 is wound. is heard to form a barrier for creating a water tank.

As described above, a plurality of wire units 500 are formed, and a plurality of second roller units 600 are formed corresponding to the number of wire units 500 . Also, a plurality of fin units 700 may be formed.

The second roller unit 600 may be provided with three, for example, and is composed of a 2-1 roller unit 610, a 2-2 roller unit 620, and a 2-3 roller unit 630. Correspondingly, as an example, three wire units 500 may also be provided, and include a first wire unit 510 , a second wire unit 520 , and a third wire unit 530 . However, the number is only an example. In addition, although the vertical positions of the second roller parts in FIG. 4 are shown to be different, this is drawn to be partially spaced apart for convenience of description due to concerns about errors in drawing representation due to overlap between wire parts.

The 2-1 roller unit 610 to the 2-3 roller unit 630 are spaced apart at predetermined intervals in the longitudinal direction and coupled to the frame unit 200 . In addition, the first wire part 510 is attached to the 2-1 roller part 610, the second wire part 520 is attached to the 2-2 roller part 620, and the third wire part 530 is connected to the second -3 Each is supported by the roller unit 630, and a plurality of pin units 710, 720, and 730 may be formed between each roller unit. At this time, since a part of the wire part must be separated from the frame part before and after the second roller part in the process of winding the wire part, so as not to interfere with the adjacent second roller part, for example, supported by the 2-1 roller part 610 It is preferable that the first wire part 510 is designed to pass under the 2-2 roller part 620 instead of the upper part in the vicinity of the 2-2 roller part 620 .

In addition, as described above, the other end of the first wire portion 510 is preferably connected to the side of the mat portion 400 or coupled to one point 410 of the tarpaulin 402 laid under the mat portion near the end, , The other end of the second wire part 510 is connected to the mat part 400 in the vicinity spaced apart by a predetermined interval in the longitudinal direction from the aforementioned one point 410 or a point of the tarpaulin 402 laid under the mat part 420, and in the same principle, the other end of the third wire part 510 and the other end of the first wire part 510 are preferably coupled to the opposite end of the vicinity 410. Due to this structure, one point of the tarpaulin 402 connected to the mat part 400 or laid under the mat part is spaced apart at a predetermined interval along the length direction, so that the other ends of the plurality of wire parts 500 are coupled to each other. The structure is formed, and when one end of the plurality of wire parts 500 is wound around the first roller part 300, as shown in FIG. 4, a tarpaulin 402 connected to the side of the mat part 400 or laid under the mat part By raising and lowering the whole, it is possible to form a partition wall for creating a water tank.

6 shows a structure in which a plurality of wire parts are coupled to the first roller part 300 . Preferably, the first roller unit 300 is preferably provided with a plurality of 1-1 roller units 310, 1-2 roller units 320, and 1-3 roller units 330, All share a single axis of rotation. The 1-1 roller unit 310, the 1-2 roller unit 320, and the 1-3 roller unit 330, respectively

At this time, the 1-1 roller unit 310, the 1-2 roller unit 320, and the 1-3 roller unit 330 each have different cross-sectional diameters, and the first wire unit 510, the second The wire unit 520 and the third wire unit 530 are coupled to each other. At this time, since the lengths of the first wire part 510, the second wire part 520, and the third wire part 530 are different, the 1-1 roller part 310 and the 1-2 roller part 320 ), the diameter of the cross section of the 1-3 roller unit 330 is also different, preferably the 1-1 roller unit 310, the 1-2 roller unit 320, and the 1-3 roller unit 330 ), it is preferable that the diameter of the cross section decreases as the value increases. This is because the length of the first wire part 510 becomes relatively short as it goes from the third wire part 530 .

A handle part 800 for rotating the first roller part 300 may be coupled to a point on the side of the first roller part 300, and the handle part 800 and the first roller part 300 may be coupled to a shaft ( 810) are connected and combined.

As described above, the pillar part 100, the frame part 200, the first roller part 300, the plurality of wire parts 500, the plurality of second roller parts 600, and the plurality of pin parts 700 It is one module, and it is preferable that the modules are provided in pairs and spaced apart at predetermined intervals in the width direction as shown in FIG. 7 .

Therefore, the other ends of the plurality of wire parts 510a, 520a, and 530a on the opposite side are connected to the side of the above-described mat part or points 410a, 420a, and 430a opposite to each other in the width direction of the plurality of points of the tarpaulin laid under the mat part. ), and when each of the first roller units 300 of the pair of modules rotates, as shown in FIG. 7, a pair of partition walls spaced apart at a predetermined interval in the width direction centered on the electric vehicle 2 this is formed At this time, the section between the bulkheads is naturally elevated as shown in FIG. 7 without a separate external force due to the elevation of the tarpaulin connected to the mat unit 400 or laid under the mat unit. Therefore, as a result, a water tank is formed in which both sides, front, and rear surfaces of the electric vehicle 2 are connected to the mat part 400 or covered by the tarpaulin 402 laid under the mat part.

As described above, in the case of the prior art, the entire tube along the parking line of the electric vehicle had to form a bulkhead to build a water tank, which requires water to be filled in the entire cross-sectional area formed along the parking line of the electric vehicle to prevent fire in the event of a fire. Since water can be brought into contact with the battery of an electric vehicle, there is a problem in that a large amount of water must be secured.

However, in the present invention, since only the waterproof fabric 402 connected to the side of the mat part 400 or laid under the mat part is lifted by the wire part 500 to form a barrier while surrounding the electric vehicle 2 (mat Due to the connection with the unit 400, a part of the mat unit body 401 can be lifted), when viewed from the side, the length of the lower part of the tarpaulin 402 connected to the mat unit 400 or laid under the mat unit An inverted trapezoidal shape, the length of which is shorter than the longitudinal length of the upper portion, is constructed. Therefore, unlike the prior art, it is possible to form a water tank with only a cross-sectional area smaller than that of the parking line where the electric vehicle 2 is parked, and as a result, the entire volume of the water tank becomes smaller than that of the prior art, preventing the battery in the event of a fire. It can extinguish a fire by contacting it with water. Therefore, fewer quantities are required than in the prior art, and there is an advantage in reducing operating costs.

Although the detailed description of the present invention described has been described with reference to preferred embodiments of the present invention, those skilled in the art or those having ordinary knowledge in the art will find the spirit and spirit of the present invention described in the claims to be described later and It will be understood that the present invention can be variously modified and changed without departing from the technical scope.
